Description
BACKGROUND
[0001] Crimping or pressing tools are well known in the art and are
used for many purposes. One of the best known uses is as a device
for mechanically securing a fastener to an electrical wire or
cable. Typically, one end of the fastener is in the form of a
cylindrical, hollow sleeve, and the other end is an eyelet, pin or
socket or similar fastener element. The sleeve is adapted for
receiving an end of the wire or cable and is clamped thereon by
deforming the sleeve through use of a crimping tool.
[0002] Another use for crimping tools involves clamping metal rings
onto tubing or other fittings. An example of tools for this
application is a tool for crimping metal fittings on cross-linked
polyethylene (PEX) tubing. These tools are adapted for making PEX
tubing connections such as used in porrtable water and radiant
heating applications. Such tools have also been used in association
with the commercially available ProPress.TM. copper systems with
transitions to PEX systems.
[0003] Crimping tools may generally be characterized as being
either of two types: circumferential or tangential.
[0004] A circumferential crimp tool typically has a set of jaws
configured to provide a pair of crimping surfaces or crimp nest
which is at least generally symmetric, for example circular,
square, hexagonal, etc. ASTM F 1807, herein incorporated by
reference, provides standards for systems of metal insert fittings
utilizing a circumferential type crimp ring element for PEX tubing.
Examples of circumferential crimping tools are described in U.S.
Pat. Nos. 5,722,284 to Linsmeyer and 6,164,106 to Nghiem.
[0005] Tangential-type crimping tools are characterized as having a
pair of projections or pincers that generally face one another.
When using such tools, the pincers are positioned about an
outwardly projecting portion or shoulders of a crimp element. ASTM
F 2098, herein incorporated by reference, provides standards for
systems of tangential type clamps for securing PEX tubing to metal
insert fittings. An example of a tangential-type crimping tool is
shown in U.S. Pat. No. 4,724,729 to Oetiker.
[0006] When using crimping tools, it is often necessary to select
the tool that is of an appropriate (i) type, i.e. circumferential
or tangential, and (ii) size for the particular application. The
selection of either a circumferential or tangential configuration
is determined by the particular application and in some instances,
by the preference of the user. The selection of an appropriate size
tool is governed by the particular application which in turn
dictates the size of the crimping elements. Since applications can
dictate a wide range of different sizes of crimping elements, and
since it is difficult if not impossible to use a single crimp tool
for all crimping elements, manufacturers typically provide
different sized tools.
[0007] Using multiple crimping tools in the field and transporting
the tools to and from the work site can be cumbersome and is
generally undesirable. In order to at least reduce the number of
crimping tools that may be required, manufacturers have provided
crimping tools that can accommodate a range of different sized
crimping elements. However, as far as is known, such tools have
only accommodated a limited range of sizes of crimping elements of
a particular type, i.e. circumferential or tangential. Thus, if
applications exist for both types of crimping elements, i.e.
circumferential and tangential, it is necessary to provide and use
two separate tools or sets of tools. Accordingly, it would be
desirable to provide a single tool that could be used with crimping
elements of not only a variety of sizes, but also with different
types such as circumferential or tangential crimping elements.
Furthermore, it would also be desirable to provide a tool that
could be used with a wide range, or multiple ranges, of sizes of
crimping elements. Providing such a tool would reduce the overall
quantity of crimping tools that an operator might otherwise
require, which would be particularly desirable when performing
crimping applications in the field.
[0008] Certain powered tools such as pressing tools, use a powered
hand unit and multiple, selectively engageable jaws or jaw sets.
Jaw sets are known that include circumferential crimping
configurations. Other jaw sets are also known for tangential
crimping applications. A problem with these tool systems, is that
the manufacturing process to produce the jaw can be costly. Also,
since each different size fitting generally requires its own jaw or
jaw set, the cost of tools to cover a range of crimping sizes and
applications increases as well as the inconvenience of having to
bring all tools and jaws to the job site. Accordingly, it would be
desirable to provide a powered tool and jaw set combination that
could be used for both circumferential and tangential type
applications.
[0009] Crimping or pressing tools that employ various jaw inserts
to accommodate a range of crimping application sizes are known. For
example, U.S. Pat. No. 6,772,618 to Frenken shows a pressing tool
having removable jaw inserts. The insert allows the operator to use
a single jaw set as a carrier for a single insert that can be
selected from a set of such inserts. The inserts may vary with
respect to size, profile or application. Additionally the inserts
are significantly lighter, smaller and less expensive to produce
than corresponding jaws. Examples of various known tool designs
using inserts include U.S. Pat. Nos. 3,706,219 to Hoffman et al;
4,576,067 to Buck; 5,113,727 to Foster; and 7,188,508 to Hamm et
al. Although generally satisfactory, this configuration still does
not provide a single assembly that can be used for both
circumferential and tangential type applications. That is, in order
to use such a jaw set and insert assembly, for crimping tangential
elements and then for circumferential elements for example, an
operator must provide and transport one or more tools for the
tangential crimping application and one or more tools for the
circumferential crimping application. After crimping the tangential
elements, the insert and possibly the jaw set, must be replaced
with those adapted for crimping circumferential elements.
Accordingly, a need remains for a single tool and jaw insert system
that can accommodate both types of applications.
SUMMARY
[0010] The present invention achieves all of the foregoing noted
objectives. In one aspect, the present invention provides a jaw set
adapted for crimping a deformable crimp element about a member. The
jaw set comprises a first jaw defining a front portion and an
oppositely directed rear portion with the inner and outer edges
extending between the front and rear portions. The jaw set also
comprises a second jaw defining a front portion and an oppositely
directed rear portion, and inner and outer edges extending between
the front and rear portions of the second jaw. Each of the first
and second jaws include an outwardly extending pincer portion near
the front portion and along the inner edge of the respective jaw.
Each of the first and second jaws also defines a recessed arcuate
surface that is accessible along the inner edge of the respective
jaw. The first and second jaws are positioned and operatively
coupled to one another such that the pincer portions of the first
and second jaws are opposite one another and define a tangential
crimping configuration, and the recessed arcuate surfaces of the
first and second jaws are also opposite one another and provide a
circumferential crimping configuration.
[0011] In another aspect, the present invention provides a jaw set
adapted for crimping a deformable crimp element about a member. The
jaw set comprises a first jaw defining a front portion and an
oppositely directed rear portion. The first jaw also defines inner
and outer edges extending between the front and rear portions. The
jaw set also comprises a second jaw defining a front portion and an
oppositely directed rear portion, and inner and outer edges
extending between the front and rear portions of the second jaw.
Each of the first jaw and the second jaw defines a recessed arcuate
surface accessible along the inner edge of the respective jaw. Each
recessed surface extends between the front portion and an interior
portion disposed between the front and rear portion of each jaw.
Each of the first jaw and the second jaw also include an outwardly
extending pincer portion proximate the interior portion of the
respective jaw. The first and second jaws are positioned and
operatively coupled to one another such that the pincer portions of
the first and second jaws are opposite one another and define and
interiorly disposed tangential crimping configuration and the
recessed arcuate surfaces of the first and second jaws are also
opposite one another and provide a circumferential crimping
configuration.
[0012] In yet another aspect, the present invention provides a
gauge adapted for determining a collection of sizes for
circumferential crimping applications and tangential crimping
applications. The gauge comprises a relatively flat planar member
defining a first face, a second oppositely directed face, and a
peripheral edge separating the first and second faces. The member
further defines (i) a first set of slotted openings each having a
span corresponding to a desired minimum diameter of a
circumferential crimping element after crimping, (ii) a second set
of slotted openings each having a span corresponding to a maximum
desired diameter of a circumferential crimping element after
crimping, and (iii) a third set of slotted openings, each having a
span corresponding to the width of a tangential crimping element
after crimping.
[0013] In addition to the specific aspects provided by the present
invention, the invention also relates to and provides a
multi-system tool or jaw set embodied in a single device or
assembly. As explained in detail herein, a single tool or jaw set
is provided that can be used with multiple systems such as one or
more circumferential systems and one or more tangential systems;
one circumferential system and another circumferential system; and
two or more circumferential systems and a tangential system for
example.

the present invention tools, jaw sets, and systems thereof.
[0016] The present invention also relates to and provides specific
types of jaw sets, pressing rings, pressing assemblies, and like
tools for performing radial pressing operations.
[0017] The present invention also relates to and provides tools and
jaw sets employing one or more specific crimping profiles or
contours as known in the art. Multiple crimping profiles such as
certain commercially known circumferential crimping contours may be
provided for the tools, jaw sets, inserts, and systems described
herein.
[0018] The present invention also relates to and provides inserts
and tools and jaw sets using such inserts, having tangential
crimping provisions incorporated into one or more inserts.
[0019] The present invention also relates to and provides systems
of multiple inserts in which one insert is used or engaged with,

DETAILED DESCRIPTION
[0055] The present invention relates to a multiple application
crimping or pressing tool that can be provided in either a manual
or powered tool configuration. A preferred embodiment of the
present invention tool is a dual application tool as described
herein.
[0056] The multiple application tool can be used for crimping or
pressing systems that are of the circumferential type, and those
that are of the tangential type. The tool features a unique head
configuration that accommodates both circumferential crimping
elements and tangential crimping elements.
[0057] The multiple application tool, in yet another embodiment,
can be utilized with one or more jaw inserts that enable a wide
range of crimping applications, i.e. circumferential and
tangential, and sizes. In particular, the multiple application tool
can also accommodate multiple types of circumferential systems and
in still further embodiments, in combination with tangential
systems.
[0058] In still additional embodiments, the multiple application
tool can be utilized with and/or incorporate ring assemblies
similar for example, to those commercially available under the
designation ProPress.RTM. Press Rings.
[0059] The term "jaw set" as used herein refers to jaw assemblies
typically comprising two jaw members that are pivotally coupled or
otherwise move relative to one another. The term jaw set refers to
such jaw assemblies used in manual tools having handles or
rearwardly directed members extending from the jaw members. The
term jaw set also refers to ring sets or ring assemblies that can
be used in crimping applications. The term also refers to such jaw
assemblies used in powered tools. The term "jaw set" also includes
similar tools or portions thereof such as those employing screw
operated assemblies that apply a compressive force. For instance,
pressing ring assemblies using screw operated manual or powered
assemblies are noted. The term also includes like tools such as
flare bars. Various representative examples of these jaw sets are
described herein. Accordingly, the present invention encompasses
not only the various jaw sets, but also manual tools and powered
tools utilizing or including such jaw sets.
[0060] FIG. 1 illustrates a preferred embodiment tool 100 according
to the present invention. The tool 100 features a circumferential
crimping surface and a pair of tangential pincer portions. The tool
100 comprises a first jaw 110 and a second jaw 120 coupled to one
another by an alignment member 150 and a hinge connector 190
described in greater detail herein.
[0061] FIG. 2 is a detailed view of the jaw set of the preferred
embodiment tool 100 depicted in FIG. 1. FIG. 2 illustrates in
greater detail the first and second jaws 110 and 120, a pair of
tangential pincer portions 136, 138, and a circumferential crimping
surface 140 defined by the jaws 110 and 120.
[0062] FIG. 3 illustrates the preferred embodiment jaw set used in
the tool 100 depicted in FIGS. 1 and 2. FIG. 3 illustrates the jaw
set with the alignment member 150 removed thereby exposing
apertures 116 and 126 defined in the first and second jaws 110 and
120, respectively.
[0063] Referring further to FIGS. 1-3, each jaw defines a forward
portion and an oppositely extending rearward portion. Each jaw also
defines inner and outer edges extending between the forward and
rearward portions. For example, the jaw 110 defines a forward
portion 111 and a rearward portion 113. And, the jaw 120 defines a
forward portion 121 and a rearward portion 123. Concerning the
noted edges, the jaw 110 defines an inner edge 143 and an
oppositely disposed outer edge 133. And, the jaw 120 defines an
inner edge 145 and an oppositely disposed outer edge 147.
Specifically and referring to FIG. 2, the inner edge 143 includes
several segments such as a front segment 143a extending between a
tangential crimping configuration and a circumferential crimping
configuration, each of which is described in greater detail herein.
The inner edge 143 also includes a medial segment 143b extending
between the circumferential crimping configuration and the region
generally overlaid by the alignment member 150. The inner edge 143
also includes a rear segment 143c generally extending from the
location of the member 150 to the distal rearward end of the jaw
110. In certain instances, each of the inner edges 143 and 145 can
include provisions as depicted in FIG. 3. There, the inner edge 143
includes an arcuate surface 143d adapted to receive and engage a
pin (not shown) as is frequently used in jaw sets. The inner edge
143 can also include a recessed surface 143e that serves to reduce
the overall length of the medial surface 143b. The inner edge 145
includes a correspondingly similar set of segments, a front segment
145a, a medial segment 145b, and a rear segment 145c. The first jaw
110 defines a front portion or nose 112 and an oppositely extending
rear portion or arm 114. Defined in the first jaw 110 is a forward
aperture 116 and a rearward aperture 118. Both apertures 116 and
118 extend through the thickness of the first jaw member 110.
Similarly, the second jaw 120 defines a nose 122 and an oppositely
extending arm 124. Defined in the second jaw 120 is a forward
aperture 126 and a rearward aperture 128. Both apertures 126 and
128 extend through the thickness of the second jaw 120. Together,
the first jaw 110 and the second jaw 120 define the tangential
pincers 136, 138. Specifically, the first jaw 110 defines a first
recessed surface 132 and the second jaw 120 defines a second
recessed surface 134. The first recessed surface 132 together with
a front leading surface of the nose 112 define a first pincer
portion 136. Similarly, the second recessed surface 134 together
with a front leading surface of the nose 122 define a second pincer
portion 138. The first and second pincer portions 136 and 138 are
preferably directly opposite from one another, and so aligned with
one another. The jaws 110 and 120 also collectively define the
circumferential crimping surface 140. Specifically, the first jaw
110 defines a first arcuate circumferential crimping surface 142
accessible along an inner edge 143 of the jaw 110. And, the second
jaw 120 defines a second arcuate circumferential crimping surface
144 accessible along an inner edge 145 of the second jaw 120. The
first and second circumferential crimping surfaces 142 and 144 are
preferably directly opposite from one another, and so aligned with
one another. The alignment member 150 serves to promote alignment
and stability between the jaws 110 and 120 during use of the tool
100. The alignment member 150 defines corresponding apertures
through which a first pin 152 and a second pin 154 extend. The pin
152 extends through the aperture 116 or otherwise rotatably engages
the jaw 110. And, the pin 154 extends through the aperture 126 or
otherwise rotatably engages the jaw 120. It will be appreciated
that the pins can be in the form of hinge members, bolts, or other
cylindrically shaped components that engage the jaws and alignment
member together. Engaged to the arm 114 of the first jaw 110 is a
first handle 160. The first handle 160 defines a forward connector
region 162 and an oppositely disposed grip 164. Preferably, defined
along the interior region of the first handle 160 is a stop member
166. Similarly, the second jaw 120 is engaged to a second handle
170. The second handle 170 defines a forward connector region 172
and an oppositely extending grip 174. Preferably defined within the
interior region of the second handle 170 is a stop member 176. The
first and second handles 160 and 170 preferably extend rearward of
the corresponding jaws to which they are engaged. The first jaw 110
is coupled to the first handle 160 by a first connector 180
extending through an aperture defined in the connector region 162
of the first handle 160 and the rearward aperture 118 defined in
the arm 114 of the first jaw 110. Similarly, the second jaw 120 is
coupled to the second handle 170 by a second connector 182 which
extends through an aperture defined in the connector region 172 of
the second handle 170 and the rearward aperture 128 defined in the
arm 124 of the second jaw 120. The first and second connectors 180
and 182 serve to engage the jaws to the respective handles. The
jaws 110 and 120 are also coupled to one another by a hinge
connector 190. The hinge connector 190 extends through
corresponding apertures defined in both of the connector regions
162 and 172 of the first and second handles 160 and 170,
respectively. The hinge connector 190 serves to provide a point
about which the forward connector regions 162 and 172 of the
handles pivot during use of the tool 100. It will be appreciated
that the first and second connectors 180 and 182, and the hinge
connector 190 can be in the form of hinge members, bolts, or other
cylindrically shaped components that engage their respective
members together.
[0064] The jaws 110 and 120 are operatively coupled to one another
such that the respective pincer portions are aligned with one
another and provide a tangential crimping configuration. That is,
the resulting pincer arrangement enables crimping of tangential
type crimping elements. Similarly, the recessed arcuate surfaces or
edges, that are accessible along the inner edges of the jaws, and
aligned with one another provide a circumferential crimping
configuration. The resulting aperture or opening 140 defined in the
jaws 110 and 120 when the jaws are closed such that the inner edge
segments 143a and 145a, and 143b and 145b are in contact or
approaching such contact, enables crimping of circumferential type
crimping elements.
[0065] Specifically, as explained in greater detail herein, the
surfaces 142 and 144 that constitute the opening 140 are configured
such that the surfaces serve as an insert receiving surface and/or
as a crimping surface. Although these surfaces are generally
referred to herein as crimping surfaces, it will be understood that
these surfaces can also be configured or serve as insert receiving
surfaces. As used herein, the term "crimping surface" refers to a
surface that contacts a workpiece or crimp element for subsequent
crimping or other compression type application. The term "insert
receiving surface" refers to a surface that receives and contacts
an insert such as an insert element also described in greater
detail herein. The insert, when received in the insert receiving
surface, then contacts the workpiece or crimp element. The insert
provides a crimping surface.
[0066] FIGS. 4-6 illustrate another preferred embodiment tool 200
according to the present invention. The tool 200 features two
circumferential crimping surfaces and a pair of tangential pincer
portions. The tool 200 comprises a first jaw 210 and a second jaw
220 coupled to one another by an alignment member 250 and a hinge
connector 290 described in greater detail. The tool 200 and its jaw
set features the previously described aspects of the tool 100 and
its jaw set.
[0067] FIG. 5 is a detailed view of the jaw set of the preferred
embodiment tool 200 depicted in FIG. 4. FIG. 5 illustrates in
greater detail the first and second jaws 210 and 220, a pair of
tangential pincer portions 236 and 238, a first circumferential
crimping surface 240a, and a second circumferential crimping
surface 240b defined by the jaws 210 and 220.
[0068] FIG. 6 illustrates the preferred embodiment jaw set used in
the tool 200 depicted in FIGS. 4 and 5. FIG. 6 illustrates the jaw
set with the alignment member 250 removed thereby exposing
apertures 216 and 226 defined in the first jaw and the second jaw,
respectively.
[0069] Referring further to FIGS. 4-6, the first jaw 210 defines a
nose 212 and an oppositely extending arm 214. Defined in the first
jaw 210 is a forward aperture 216 and a rearward aperture 218. Both
apertures 216 and 218 extend through the thickness of the first jaw
member 210. Similarly, the second jaw 220 defines a nose 222 and an
oppositely extending arm 224. Defined in the second jaw 220 is a
forward aperture 226 and a rearward aperture 228. Both apertures
226 and 228 extend through the thickness of the second jaw 220.
Together, the first jaw 210 and the second jaw 220 define the
tangential pincer portions 236, 238. Specifically, the first jaw
210 defines a first recessed surface 232 and the second jaw 220
defines a second recessed surface 234. The first recessed surface
232 together with a front leading surface of the nose 212 define a
first pincer portion 236. Likewise, the second recessed surface 234
together with a front leading surface of the nose 222 define a
second pincer portion 238. The jaws 210 and 220 also collectively
define a first circumferential crimping surface 240a. Specifically,
the first jaw 210 defines a first circumferential crimping surface
242a. And, the second jaw 220 defines a second circumferential
crimping surface 244a. The jaws 210 and 220 also collectively
define a second circumferential crimping surface 240b.
Specifically, the first jaw 210 defines a third circumferential
crimping surface 242b. The second jaw 220 defines a fourth
circumferential crimping surface 244b. The alignment member 250
serves to promote alignment and stability between the jaws 210 and
220 during use of the tool 200. The alignment member 250 defines
corresponding apertures through which a first pin 252 and a second
pin 254 extend. The pin 252 extends through the aperture 216 or
otherwise rotatably engages the jaw 210. And, the pin 254 extends
through the aperture 226 or otherwise rotatably engages the jaw
220. Engaged to the arm 214 of the first jaw 210 is a first handle
260. The first handle 260 defines a forward connector region 262
and an oppositely disposed grip 264. Preferably, defined along the
interior region of the first handle 260 is a stop member 266.
Similarly, the second jaw 220 is engaged to a second handle 270.
The second handle 270 defines a forward connector region 272 and an
oppositely extending grip 274. Preferably defined within the
interior region of the second handle 270 is a stop member 276. The
first and second jaws 210 and 220 are coupled to one another by a
first connector 280 extending through an aperture defined in the
connector region 262 of the first handle 260 and the rearward
aperture 218 defined in the arm 214 of the first jaw 210.
Similarly, the jaws 210 and 220 are also coupled to one another by
a second connector 282 which extends through an aperture defined in
the connector region 272 of the second handle 270 and the rearward
aperture 228 defined in the arm 224 of the second jaw 220. The
hinge connector 290 extends through corresponding apertures defined
in both of the connector regions 262 and 272 of the first and
second handles 260 and 270, respectively.
[0070] The operation of tools 100 and 200 can be described by
reference to FIG. 1 and depiction of tool 100. A user, wishing to
fasten or otherwise engage a crimp element (not shown) which for
example, has been appropriately positioned such as along an
interface of tubing to be joined, determines whether the crimp
element is of the tangential or circumferential type. The user then
opens the jaws 110 and 120, i.e. the jaw set, by separating the
handles 160 and 170 from one another. The jaw set is then
positioned about the crimp element of interest. If the crimp
element is a tangential type, then the pincer portions 136 and 138
of the tangential crimping surface defined by the jaws 110 and 120
are placed across and in contact with the outwardly projecting
shoulders of the crimp element. The user then urges the handles 160
and 170 of the tool 100, together, thereby also moving the pincer
portions 136 and 138 toward one another. In the event the crimp
element is of the circumferential type, the opened jaw set is
positioned about the element such that the element is between the
circumferential crimping surfaces 142 and 144. Upon closure of the
jaw set by urging the handles together, the circumferential
crimping surfaces contact and engage the crimp element and fasten
that element in place.
[0071] Tools 100 and 200 are examples of preferred embodiments of
manual tools in accordance with the present invention. The present
invention also includes manual tools like tools 100 and 200, but
instead of providing one or two circumferential crimping surfaces
in combination with a pair of tangential pincers, provide three or
more circumferential crimping surfaces in combination with a pair
of tangential pincers.
[0072] In addition to manual crimping tools, the present invention
also provides powered crimping tools, and particularly, jaw sets
adapted for use with powered tools.
[0073] FIG. 7 illustrates a preferred embodiment jaw set 300,
adapted for use with powered tools according to the present
invention. The jaw set 300 comprises a first jaw 310 and a second
jaw 320 coupled to one another by an alignment member 350 and
associated members described in greater detail.
[0074] Referring to FIG. 7, the first jaw 310 defines a nose 312
and an oppositely extending arm 314. Defined in the first jaw 310
is an aperture (not shown) through which a pin 352 extends.
Similarly, the second jaw 320 defines a nose 322 and an oppositely
extending arm 324. Defined in the second jaw 320 is an aperture
(not shown) through which a pin 354 extends. Together, the first
jaw 310 and the second jaw 320 define a pair of tangential crimping
pincers 336, 338. Specifically, the first jaw 310 defines a first
recessed surface 332 and the second jaw 320 defines a second
recessed surface 334. The first recessed surface 332 together with
a front leading surface of the nose 312 define a first pincer
portion 336. Similarly, the second recessed surface 334 together
with a front leading surface of the nose 322 define a second pincer
portion 338. The jaws 310 and 320 also collectively define a
circumferential crimping surface 340. Specifically, the first jaw
310 defines a first circumferential crimping surface 342. And, the
second jaw 320 defines a second circumferential crimping surface
344. The alignment member 350 serves to promote alignment and
stability between the jaws 310 and 320 during use of the tool 300.
The alignment member 350 defines corresponding apertures through
which the first pin 352 and the second pin 354 extend. The
alignment member 350 also defines an aperture 356 which serves to
receive a retention member (not shown) when the jaw set 300 is
engaged with a powered tool, as described in greater detail
herein.
[0075] FIG. 8 illustrates another preferred embodiment jaw set 400
adapted for use with a powered tool according to the present
invention. The jaw set 400 comprises a first jaw 410 and a second
jaw 420 coupled to one another by an alignment member 450 and
associated members described in greater detail. The first jaw 410
defines a nose 412 and an oppositely extending arm 414. Defined in
the first jaw 410 is an aperture (not shown) through which a pin
452 extends. Similarly, the second jaw 420 defines a nose 422 and
an oppositely extending arm 424. Defined in the second jaw 420 is
an aperture (not shown) through which a pin 454 extends. Together,
the first jaw 410 and the second jaw 420 define a pair of
tangential pincer portions 436, 438. Specifically, the first jaw
410 defines a first recessed surface 432 and the second jaw 420
defines a second recessed surface 434. The first recessed surface
432 together with a front leading surface of the nose 412 define a
first pincer portion 436. Similarly, the second recessed surface
434 together with a front leading surface of the nose 422 define a
second pincer portion 438. The jaws 410 and 420 also collectively
define a first circumferential crimping surface 440a. Specifically,
the first jaw 410 defines a first circumferential crimping surface
442a. And, the second jaw 420 defines a second circumferential
crimping surface 444a. And, the jaws 410 and 420 additionally
collectively define a second circumferential crimping surface 440b.
Specifically, the first jaw 410 defines a third circumferential
crimping surface 442b. And, the second jaw defines a fourth
circumferential crimping surface 444b. The alignment member 450
serves to promote alignment and stability between the jaws 410 and
420 during use of the tool 400. The alignment member 450 defines
corresponding apertures through which the first pin 452 and the
second pin 454 extend. The alignment member 450 also defines an
aperture 456 that serves to receive a retention member (not shown)
when the jaw set 400 is engaged with a powered tool, as described
in greater detail herein.
[0076] Jaw sets 300 and 400 are examples of preferred embodiment
jaw sets adapted for use with powered tools in accordance with the
present invention. The invention also includes jaw sets adapted for
use with powered tools that include combinations of a pair of
pincers for tangential crimping applications and three or more
circumferential crimping surfaces.
[0077] FIG. 9 is a perspective view of the jaw set 400 depicted in
FIG. 8, engaged with a powered pressing tool 500. The tool 500
comprises a housing 510, a handle 520, a battery pack 530, a
forward end 540, and an oppositely directed rear end 550. The
battery pack 530 preferably is selectively engageable along the
distal lowermost end of the handle 520. The tool 500 includes a
trigger 525 that upon actuation, initiates activation of the tool
500. Projecting from the front face of the forward end 540 is a
receiving assembly 545 that is adapted to selectively engage a jaw
set such as jaw sets 300 or 400, depicted in FIGS. 7 and 8
respectively.
[0078] Disposed within the interior of the housing 510 is an
electric motor and drive assembly for imparting a drive force to
the jaw set, such jaw set 400, engaged and received at the forward
end 540 of the tool 500. A receiving assembly 545 forwardly
projecting from the end 540 of the tool 500, includes provisions
for receiving and engaging the jaw set 400. A retention member 548
or other similar component or assembly serves to retain and couple
the jaw set 400 to the tool 500. The retention member 548 is
releasably engageable with a jaw set by extending into or through
the aperture 456 defined in the alignment member 450 of the jaw set
400, for example. Typically, upon pulling the member 548 to a
release position, the member 548 is retracted from the aperture 456
and the jaw set 400 can be withdrawn from the tool 500. Details of
the components, operation and assembly of the tool 500 are
disclosed in various patents, such as for example, U.S. Pat. Nos.
5,111,681 to Yasui et al.; 5,611,228 to Dummermuth; 6,000,680 to
Kimura et al.; 6,202,290 to Kewitz et al.; 6,244,085 to Dummermuth;
6,276,186 to Frenken; 6,401,515 to Frenken; 6,510,719 to Goop;
6,510,723 to Amherd; 6,662,621 to Amherd; and 6,718,870 to
Frenken.
[0079] FIG. 10 illustrates a preferred embodiment gauge 600 in
accordance with the present invention. The gauge 600 provides
dimensional indicators for estimating or determining a range of
sizes for circumferential crimping applications and tangential
crimping applications. Preferably, and as depicted, the gauge 600
can be in the form of a "Go-No-Go" gauge as that term is understood
by those skilled in the art. The gauge 600 serves as an inspection
tool to check the extent of crimping or compression applied to a
workpiece. The gauge 600 is a measuring tool that does not
necessarily return a size in the literal sense, but instead returns
a state. Specifically, the gauge 600 provides a series of
circumferential, i.e. according to ASTM F1807, indicators such as
610, 620, 630, 640, 650, and 660. The gauge 600 also provides a
series of tangential indicators such as 670, 680, and 690. As will
be appreciated, each dimensional indicator is provided along the
periphery of the gauge 600. The "Go-No-Go" aspect of the gauge 600
can be used to determine whether a circumferential crimped element
has been sufficiently compressed about an underlying member. If,
after crimping, the crimped element has an outer diameter small
enough to fit within the Go indicator and has an outer diameter
that is too large to fit within the corresponding No-Go indicator,
then the element has been sufficiently compressed. If however, the
crimped element fits in both of the Go and No-Go indicators, then
the element has been excessively or overly crimped. If instead, the
crimped element does not fit within the Go indicator, then the
element has not been sufficiently crimped. The gauge is preferably
formed from a relatively flat and thin sheet of a durable material
such as metal or certain plastics.
[0080] The circumferential indicators of the gauge 600 are
preferably slotted openings having a span or access width that
corresponds to the desired range of diameters of the
circumferential crimping element after crimping. That is, the
preferred embodiment gauge defines a collection of openings, each
of which corresponds to a minimum and maximum desired diameter of a
circumferential crimping element after crimping. It is also
preferred that the interior portion of each opening define an
arcuate edge, and preferably, a semi-circular edge, having a
diameter equal or substantially so, to the access width of the
respective opening. Thus, for example, the circumferential
indicator 610 defines an arcuate edge 612 that preferably extends
through an arc of 1800 between a pair of side edges 614 and 616.
The side edges are parallel to one another and spaced apart a
distance corresponding to the desired diameter indicative of the
indicator 610.
[0081] The tangential indicators of the gauge 600 are also
preferably slotted openings. The span or width of each opening
corresponds to the preferred maximum width of a tangential crimping
element after crimping. This width, as will be appreciated by those
skilled in the art, is the distance between the shoulders of the
crimping element in its post-crimp state. It is frequently
desirable, and often necessary, to utilize a tangential indicator
to determine whether sufficient crimping has occurred. Depending
upon the material of the crimp element and/or its physical
characteristics, and also the characteristics of any underlying
workpiece, after crimping, the gap between the shoulders of a
crimped tangential type element may increase or "spring back" due
to resiliency or elastic memory of the crimp element. Thus, it is
beneficial to use a tangential crimp indicator to confirm that
sufficient crimping has occurred. Inherently, it is likely that
spring back occurs. The degree of spring back typically varies
depending upon fitting size. This is the reason that the preferred
embodiment gauge 600 provides indications for multiple sizes.
[0082] The present invention also provides a jaw configuration, a
jaw set using such configuration, one or more jaw inserts, and a
system of these features adapted for use with a manual or powered
tool or tool assembly. Specifically, in this aspect, the invention
provides a jaw configuration for a tool, manual or powered, which
can be used for crimping or pressing applications, and which can be
used in conjunction with one or more inserts.
[0083] More specifically, the present invention provides a wide
variety of different style and different size inserts for use in
conjunction with a jaw set as described herein. For example, in
this aspect of the invention, a jaw set is provided that defines an
insert receiving surface which in turn, receives an insert member
that can be used to crimp a crimp element. The jaw set can be used
to crimp a range of different sized crimp elements by appropriate
selection of an insert of a size corresponding to the element to be
crimped. In addition to the inserts varying from one another in
size, the inserts may also vary from one another in one or more
other characteristics such as, but not limited to crimp shape.
Furthermore, in accordance with the present invention, jaw sets
and/or inserts can be provided to accommodate multiple types or
combinations of circumferential crimping systems.
[0084] FIGS. 11 to 15 illustrate a preferred embodiment jaw and an
insert member in accordance with the present invention. Although
the jaw depicted in these figures is of the type adapted for use in
a powered tool, it will be appreciated that the following
description is equally applicable to a manually powered tool.
Specifically, FIGS. 11 and 12 illustrate a preferred embodiment jaw
700 comprising a jaw body 710, a nose 720, an oppositely extending
arm 730, and a recessed insert receiving region 740. The jaw 700
defines first and second oppositely directed lateral faces 702 and
704, an outer edge 706, and an inner edge 708, both edges extending
about opposite peripheral regions of the jaw 700. The jaw 700
preferably defines an aperture 750 for receiving an engagement
member, such as for coupling an alignment member (not shown)
thereto. The jaw 700 can also define a rearwardly disposed and
preferably recessed region 760 that can carry logo(s) or other
markings as desired.
[0085] The insert receiving region 740 is preferably defined by a
concave, recessed, arcuate surface 742 that extends along the inner
edge 708 of the jaw 700. Defined along one or both of lateral faces
702 and 704 of the jaw 700 are a plurality of retention members 744
and 746. The retention members 744 and 746 serve to align and
preferably retain an insert member within and in contact with the
surface 742 of the insert receiving region 740. Although the
invention includes a wide array of designs and configurations for
the retention members, a preferred configuration is that each
member be in the form of an outwardly extending member. In certain
instances, the retention members can be in the form of spring
loaded or otherwise outwardly biased displaceable members that are
received by or otherwise engaged with corresponding apertures or
recesses in the insert. The insert can be retained to its
corresponding jaw in nearly any fashion. For example, the present
invention includes the use of magnetic retention strategies and the
use of straps formed from elastomeric materials or metals that
extend about the insert and outer surface of the jaw. A wide array
of other retention strategies are contemplated and included in the
present invention such as the use of selectively releasable pins or
threaded connectors that temporarily affix an insert to the jaw.
The surface 742, if used in conjunction with an insert as
previously described, would then correspond to an insert receiving
surface as that term is used herein. However, the surface 742 could
also serve as a crimping surface.
[0086] FIGS. 13 and 14 illustrate a preferred embodiment insert
member 800 in accordance with the present invention. The insert
member 800 is preferably in the shape of a semicircle and includes
a pair of lateral side walls 810 and 820 and an arcuate member 830
extending between the walls 810 and 820. The member 830 defines two
oppositely directed surfaces, a convex mating surface 840 and an
oppositely directed concave crimping or working surface 850. Each
of the sidewalls 810 and 820 preferably include provisions for
engaging one or more retention members provided in a corresponding
jaw. For example, the insert 800 includes a plurality of receiving
apertures or slots that engage the retention members 744 and 746 of
the jaw 700 shown in FIG. 11 once the insert 800 is appropriately
positioned in the insert receiving region 740 of the jaw 700.
Specifically in this regard, the sidewall 810 defines apertures 812
and 814, and the sidewall 820 defines apertures 822 and 824.
[0087] The various inserts described herein feature outer surfaces
for engagement and contact with jaws described herein. That is, the
inserts feature an outer or backside surface configured to contact
and preferably seat against a corresponding insert receiving
surface defined in the jaw member. The inserts also feature an
oppositely directed surface referred to herein as a crimping
surface as such surface contacts a workpiece or crimp element for
subsequent crimping. Referring to FIGS. 11-15 again, upon placement
of insert member 800 in the jaw 700, the convex mating surface 840
of the insert 800 contacts and is engaged alongside the insert
receiving region 740, and specifically the insert receiving surface
defined therein of the jaw 700. Upon use of the jaw 700 and the
insert 800, the crimping surface 850 of the insert contacts the
workpiece or crimp element.
[0088] FIG. 15 is a perspective view of an assembly of the
preferred embodiment jaw 700 and the preferred embodiment insert
member 800 engaged therewith.
[0089] It will be appreciated that in using the jaw and insert
assembly, two of the assemblies are used to provide a jaw set. And
two or more inserts or insert members are utilized in a typical
crimping application.
[0090] A jaw or jaw set and an insert member may be provided or
implemented in combination with the dual crimping system described
herein. That is, the present invention also provides a jaw set,
adapted for use with a manual or powered tool or tool assembly,
that includes jaw provisions for receiving insert members in
combination with one or more tangential and/or circumferential
crimping provisions. For example, the present invention includes a
jaw set comprising provisions for receiving insert members in
combination with a pair of tangential pincing portions. The
invention also includes a jaw set comprising provisions for
receiving insert members in combination with one or more
circumferential crimping surfaces. The present invention also
includes a jaw set having a combination of provisions for receiving
insert members, a pair of tangential pincing portions, and
circumferential crimping surfaces. In addition, the present
invention includes a jaw set having multiple provisions for
receiving insert members, such as a first set of insert members and
a second set of insert members. The two or more different sets of
insert members can vary by size, shape or configuration. It is also
contemplated, to provide a jaw set that includes multiple
provisions for receiving two or more sets of insert members in
combination with a pair of tangential pincing portions, and/or one
or more circumferential crimping surfaces. And, as previously
noted, the jaw sets can be configured to accommodate multiple types
or combinations of different types of circumferential crimping
systems.
[0091] FIG. 16 illustrates a preferred embodiment jaw comprising
provisions for receiving insert members in combination with a pair
of tangential pincing portions. Specifically, FIG. 16 illustrates a
jaw assembly 900 comprising a jaw 910 and an insert member 980. The
jaw 910 defines a nose 912, an outwardly projecting pincer portion
936, and an arcuate insert receiving surface 950 adapted to receive
the insert member 980. The jaw assembly 900 can be used in a jaw
set to crimp tangential type crimping elements by use of the
resulting pincer portions, one of which is shown as 936, and in
addition, to also crimp a range of circumferential type crimping
elements upon appropriate selection of the desired insert, such as
insert 980. It will also be appreciated that the receiving surface
950, and a corresponding receiving surface in another complimentary
jaw (not shown), can itself be utilized as a circumferential
crimping provision.
[0092] FIGS. 17 and 18 illustrate jaw assemblies having provisions
for receiving insert members in combination with one or more
circumferential crimping surfaces. Specifically, FIG. 17
illustrates a jaw assembly 1000 comprising a jaw 1010 and an insert
member 1080. The jaw 1010 defines a nose 1012 and an arcuate
receiving surface 1050 sized and adapted to receive the insert
member 1080. The jaw 1010 also defines a circumferential crimping
surface 1040. FIG. 18 illustrates a jaw assembly 1100 comprising a
jaw 1110 and an insert member 1180. The jaw 1110 defines a nose
1112 and an arcuate receiving surface 1150 sized and adapted to
receive the insert member 1180. The jaw 1110 also defines a first
circumferential crimping surface 1140a and a second circumferential
crimping surface 1140b. The jaw assembly 1000 and the jaw assembly
1100 can each be used in a jaw set to crimp a relatively wide range
of different sizes of circumferential type crimping elements. The
jaw assembly 1000 enables circumferential crimping of a wide range
of sizes, shapes, and configurations, since inserts of different
sizes can be selected and positioned in the receiving surface 1050.
The crimping surface 1040 can for example, be of a size that is
popular or common. The jaw assembly 1100 is similar to jaw assembly
1000, however provides two sets of circumferential crimping
provisions, i.e. 1140a and 1140b. This pair of crimping provisions
may be of appropriate sizes to accommodate two common or popular
sizes of crimping elements. Again, it will be appreciated that the
receiving surface 1050 of the jaw 1010 and the receiving surface
1150 of the jaw 1110 (and corresponding surfaces in complimentary
jaws forming useable jaw sets) can be used as circumferential
crimping provisions.
[0093] FIG. 19 illustrates a jaw assembly having a combination of
provisions for receiving insert members, a pair of tangential
pincing portions, and circumferential crimping surfaces.
Specifically, FIG. 19 illustrates a jaw assembly 1200 comprising a
jaw 1210 and an insert member 1280. The jaw 1210 defines a nose
1212, a pincing portion 1236, a recessed arcuate surface 1250 sized
and adapted to receive the insert member 1280, and a
circumferential crimping surface 1240. As will be appreciated, this
jaw assembly 1200 can be used in a jaw set for crimping (i)
tangential crimping elements by use of tangential pincing portion
1236 and a complimentary portion (not shown) and (ii) a variety of
different sizes of circumferential crimping elements, by use of the
insert receiving surface 1250 and corresponding insert 1280, and
circumferential crimping provisions provided by surface 1240 and
complimentary portions (not shown).
[0094] FIG. 20 illustrates a jaw assembly having multiple
provisions for receiving insert members, such as a first set of
insert members and a second set of insert members. Specifically,
FIG. 20 illustrates a jaw assembly 1300 comprising a jaw 1310 and a
first insert member 1380a and a second insert member 1380b. The jaw
1310 defines a nose 1312 and a first receiving surface 1350a sized
and adapted to receive the insert member 1380a. The jaw 1310 also
defines a second recessed receiving surface 1350b that is sized and
adapted to receive the insert member 1380b. The jaw assembly 1300
can be used in a corresponding jaw set to crimp a wide range of
sizes of circumferential crimping elements by appropriate selection
of sizes of inserts 1380a and 1380b. It is contemplated that the
jaw assembly 1300 would be beneficial when crimping numerous
circumferential style elements having a significantly wide range of
different sizes. Also, as previously noted, in accordance with the
invention, one or both of the receiving surfaces 1350a and 1350b
can themselves constitute circumferential crimping work
surfaces.
[0095] FIG. 21 illustrates a jaw assembly having multiple
provisions for receiving two or more sets of insert members in
combination with tangential pincing portions. Specifically, FIG. 21
illustrates a jaw assembly 1400 comprising a jaw 1410 and a first
insert member 1480a and a second insert member 1480b. The jaw 1410
defines a nose 1412 and a pincing portion 1436. The jaw 1410 also
defines a first recessed receiving surface 1450a and a second
recessed receiving surface 1450b. The receiving surface 1450a is
sized and adapted to receive the first insert member 1480a. The
second receiving surface 1450b is sized and adapted to receive the
second insert member 1480b. As previously described, the provision
of a plurality of insert receiving surfaces enables the jaw
assembly 1400 and corresponding jaw set to accommodate a wide range
of sizes of circumferential style crimping elements. And, the
provision of tangential crimping surfaces, such as the pincer
portion 1436, enables the jaw assembly 1400 to also be used for
tangential crimping applications.
[0096] FIG. 22 illustrates a jaw assembly 1500 comprising a jaw
1510, a first insert member 1580a, and a second insert member
1580b. The jaw 1510 defines a nose 1512 and first and second
arcuate receiving surfaces 1550a and 1550b, respectively. The first
receiving surface 1550a is sized and adapted to receive the first
insert member 1580a. Similarly, the second insert surface 1550b is
sized and adapted to receive the second insert member 1580b. The
jaw 1510 also defines a circumferential crimping surface 1540. As
will be understood from the previous descriptions of preferred
embodiment jaws, the jaw assembly 1500, when used in a jaw set,
accommodates an extremely wide range of different sizes of
circumferential style crimping elements.
[0097] FIG. 23 illustrates a preferred embodiment jaw assembly 1600
comprising a jaw 1610 and first and second insert members 1680a and
1680b. The jaw 1610 defines a nose 1612 and a tangential pincing
portion 1636. The jaw 1610 also defines a first arcuate receiving
surface 1650a that is sized and adapted to receive the insert
member 1680a. The jaw 1610 also defines a second arcuate receiving
surface 1650b that is sized and adapted to receive the second
insert member 1680b. The jaw 1610 also defines a circumferential
crimping surface 1640. In addition to the jaw assembly 1600
accommodating a great range of different sizes of circumferential
style crimping elements, the jaw 1600 can also be used for crimping
tangential style crimp elements.
[0098] The present invention also provides a jaw set, or tool
utilizing such jaw set, that includes a tangential crimping
configuration located within the interior of the tool. That is,
instead or in addition to, the provision of pincer portions
disposed along the nose or front portion of the jaws, such pincer
portions can be disposed within the interior of the jaw set, and
accessible from one or more circumferential crimping provisions
upon opening the jaws apart from one another. It is contemplated
that the provision of interiorly disposed pincers that provide a
tangential crimping configuration can also be provided in
conjunction with a plurality of circumferential crimping
provisions.
[0099] FIG. 24 illustrates another preferred embodiment jaw
assembly 1700 comprising a first jaw 1710 and a corresponding
second jaw 1720. This embodiment is an example of the present
invention providing inserts that define a tangential crimping
configuration, and particularly, one that is defined within the
interior of the tool or jaw set. The jaw assembly 1700 features a
tangential pincing configuration defined within the interior of the
jaw assembly, by pincer members 1752 and 1762. The first jaw 1710
defines a nose 1712, an oppositely located end 1714 and an inner
surface 1708. Similarly, the second jaw 1720 defines a nose 1722,
an oppositely located end 1724 and an inner surface 1718. The jaw
assembly 1700 is adapted for use in a powered pressing tool, and
so, surfaces 1708 and 1718 are adapted for contact with rollers or
other pressing components of the pressing tool. It will be
appreciated that the present invention includes manual, unpowered
versions of the jaw assembly 1700. The jaw assembly 1700 defines an
interior receiving region for accepting crimping inserts 1780 and
1790. The first jaw 1710 defines a receiving surface 1750 which
contacts an outer surface of the insert 1780. Similarly, the second
jaw 1720 defines a receiving surface 1760 that contacts an outer
surface of the insert 1790. An interiorly disposed tangential
crimping provision can be accessed by removing the inserts 1780 and
1790. Upon such removal, pincer portions 1752 and 1762 can then be
utilized for tangential crimping applications as described
herein.
[0100] FIG. 25 is a detailed view of the insert 1790 depicted in
FIG. 24. The insert 1790 defines an outer surface 1792 which is
received by and engages the receiving surface 1760 of the second
jaw 1720. The insert 1790 also defines one or more circumferential
crimping surfaces such as 1794 and 1796. It will be appreciated
that the present invention includes systems utilizing multiple
inserts. For example, an insert such as insert 1790 can be used
with additionary inserts that are received in surfaces 1794 and
1796. In this embodiment of the invention, a primary insert such as
insert 1790 is positioned within a corresponding tool, and
specifically in contact with an insert receiving surface defined
within the tool. Next, one or more secondary inserts are then
engaged with the primary insert, and specifically, in contact with
the surfaces 1794 and/or 1796. Thus, the present invention includes
inserts that provide multiple circumferential crimping provisions
and/or define multiple insert receiving surfaces for accepting one
or more secondary inserts. This strategy significantly increases
the flexibility and application of the present invention tool, jaw
sets, and inserts, to a wide array of uses.
[0101] As noted, the multiple application tool can also be in the
form of ring sets or pressing ring assemblies, as known in the art.
FIGS. 26-32 illustrate two representative examples of preferred
embodiment pressing ring assemblies in accordance with the present
invention. Specifically, FIGS. 26-28 illustrate a first preferred
embodiment pressing ring assembly 1800. The assembly 1800 is
depicted as a Propress.RTM. XLC/Propress.RTM. pressing assembly.
The assembly 1800 includes a spring that biases the two portions or
jaws of the ring assembly toward one another. The assembly is used
by placing it over a fitting or element to be compressed or
crimped, and then applying a compressive force at the nose end of
the hinged jaws. Specifically, assembly 1800 comprises an upper jaw
1810, a lower jaw 1820 pivotally attached to the upper jaw 1810
such as by use of a pivot pin 1850. The upper jaw 1810 defines an
upper crimping surface 1842 generally extending between a rear
region 1813 at the vicinity of the pivot pin 1850, and a distal
nose region 1836. The lower jaw 1820 defines a lower crimping
surface 1844 generally extending between a rear region 1823 at the
vicinity of the pivot pin 1850, and a distal nose region 1838.
Together, the crimping surfaces 1842 and 1844 define a
circumferential crimping surface 1840. Also preferably defined
adjacent the nose regions 1836 and 1838 of the jaws 1810 and 1820,
respectively, is a circumferential crimping configuration defined
by a pair of recessed surfaces 1832 and 1834. The pressing assembly
1800 also comprises an optional compression segment 1870 disposed
generally between the upper and lower jaws 1810 and 1820 and
adjacent the rear regions of those jaws. The assembly 1800
additionally comprises a pair of opposing support members 1852 and
1854, fasteners 1860 and 1862, and retaining rings 1856 and 1858. A
torsion spring 1864 is preferably utilized for biasing, as
previously noted. Roll pins such as pins 1870, 1872, 1874, and 1876
can also be utilized in the ring pressing assembly 1800. In use,
the assembly 1800 is positioned as desired, such as over a fitting
or element to be compressed, and then a tool providing a
compressive force, is then engaged in receiving regions 1802 and
1806 defined in the upper and lower jaws, respectively, and
preferably in contact with surfaces 1804 and 1808 defined in the
receiving regions 1802 and 1806. The surfaces 1804 and 1808
preferably define a concave or bowl-shaped depression. This
configuration promotes receipt and engagement of members of a
compressive force applying tool.
[0102] FIG. 29 is a side view of the pressing ring assembly similar
to that depicted in FIGS. 26-28, utilizing a pair of removable
inserts similar to those shown in FIGS. 24 and 25. Specifically,
FIG. 29 illustrates the pressing ring assembly 1800 using a first
insert 1880 and a second insert 1890. The first insert 1880 defines
a first crimping surface 1884 and a second crimping surface 1886.
The second insert 1890 defines a first crimping surface 1894 and a
second crimping surface 1896. As will be understood, the inserts
1880 and 1890 can also serve as primary inserts and be used in
conjunction with secondary inserts that are received and engaged in
the corresponding pairs of surfaces 1884 and 1894, and surfaces
1886 and 1896.
[0103] FIGS. 30-32 illustrate another preferred embodiment pressing
ring assembly 1900. The assembly 1900 includes a spring that biases
the two portions or jaws of the ring assembly toward one another.
The assembly is used by placing it over a fitting or element to be
compressed or crimped, and then applying a compressive force at the
nose end of the hinged jaws. Specifically, assembly 1900 comprises
an upper jaw 1910, and a lower jaw 1920 pivotally attached to the
upper jaw 1910 such as by use of a pivot pin 1950. The upper jaw
1910 defines an upper crimping surface 1942 generally extending
between a rear region 1913 at the vicinity of the pivot pin 1950,
and a distal nose region 1936. The lower jaw 1920 defines a lower
crimping surface 1944 generally extending between a rear region
1923 at the vicinity of the pivot pin 1950, and a distal nose
region 1938. Together, the crimping surfaces 1942 and 1944 define a
circumferential crimping surface 1940. Also preferably defined
adjacent the nose regions 1936 and 1938 of the jaws 1910 and 1920,
respectively, is a tangential crimping configuration defined by a
pair of recessed surfaces 1932 and 1934. The assembly 1900 also
comprises a retaining ring 1956. A torsion spring 1964 is
preferably utilized for biasing, as previously noted. Roll pins
such as pins 1970 and 1972 can also be utilized in the ring
pressing assembly 1900. In use, the assembly 1900 is positioned as
desired, such as over a fitting or element to be compressed, and
then a tool providing a compressive force, is then engaged in
receiving regions 1902 and 1906 defined in the upper and lower
jaws, respectively, and preferably in contact with surfaces 1904
and 1908 defined in the receiving regions 1902 and 1906. The
surfaces 1904 and 1908 preferably define a concave or bowl-shaped
depression. This configuration promotes receipt and engagement of
members of a compressive force applying tool. The assembly 1900 can
also be used in conjunction with one or more inserts such as shown
in FIG. 29 and other inserts as described and shown herein.
[0104] FIG. 33 illustrates yet another preferred configuration for
inserts according to the present invention. As previously described
with regard to FIGS. 24 and 25, inserts can be provided with
tangential crimping provisions defined proximate the rear of the
insert. The invention includes insert embodiments having the
tangential crimping provisions defined at or near the middle region
of the insert as shown in FIG. 33; and the front or nose of the
insert as shown in FIG. 34.
[0105] Specifically, insert pair 2000 as shown in FIG. 33 comprises
a first insert 2010 defining an outer surface 2002 that is adapted
to be received and engaged within an insert receiving region of a
tool or jaw set as described herein. The insert 2010 defines a
first circumferential crimping surface 2012 and a second
circumferential crimping surface 2014. The surfaces 2012 and 2014
are generally separated by a pincer portion member 2020. The insert
2010 also defines a nose region 2004. The insert pair 2000 also
comprises a second insert 2030 defining an outer surface 2032 that
is adapted to be received and engaged within an insert receiving
region of a tool or jaw set as described herein and a nose region
2034. The insert 2030 defines a first circumferential crimping
surface 2042 and a second such surface 2044. The surfaces 2042 and
2044 are generally separated by a pincer portion member 2050. The
members 2020 and 2050 constitute a tangential crimping
configuration as described herein.
[0106] FIG. 34 illustrates another preferred pair of inserts as
described. Specifically, insert pair 2100 comprises a first insert
2110 defining an outer surface 2102 that is adapted to be received
and engaged within an insert receiving region of a tool or jaw set
as described herein. The insert 2110 defines a first
circumferential crimping surface 2112 and a second circumferential
