Description
The present invention relates generally to knot-typing devices and
pertains, more specifically, to a device for use in tying a true
barrel knot, or blood knot, between lines.
The art of angling requires numerous diverse skills and many
anglers strive to become proficient in all of the skills required.
One such skill is the tying of knots for a variety of purposes.
Among those knots found in angling perhaps the most difficult knot
to tie is the barrel knot, also known as the blood knot, which is
usually employed in tying consecutive line segments together. For
example, where a tapered leader is constructed of several
consecutive line segments, each line segments being a filament of a
diameter different from the diameter of the next consecutive line
segment, the line segments are usually tied together with barrel
knots.
In a barrel knot, the lines which are joined together are each
wrapped or coiled around the other over several turns and the knot
has the appearance of two confronting helixes with the end portions
of the lines locked between the confronting helixes. While it is
possible to tie a barrel knot so that the end portions of both
lines emerge from between the helixes in the same direction
transverse to the lines, in a true barrel knot these end portions
are made to emerge in opposite directions. Thus, the tying of a
true barrel knot requires skill, dexterity and patience not only in
holding and wrapping the lines over one another, but in threading
the end portions between the confronting helixes in the proper
directions.
The problems presented in tying such a knot are compounded when the
knot is tied in the field where the angler is already burdened with
his equipment and is often hampered by cold fingers, wet lines and
other adverse conditions, all of which have a deleterious effect
upon his dexterity and patience.
A variety of knot-tying devices have been made available for
assisting the angler in tying barrel knots. Some of these devices
are portable enough to be carried into the field. However, such
devices have either been relatively complex in their design and
construction, and therefore relatively expensive, or have required
relatively elaborate procedures for their use, thus reducing their
effectiveness as an aid to the angler in the field. In addition,
many of these devices do not aid in the tying of true barrel knots.
It would be advantageous to have available a simple, inexpensive
knot-tying device which would enable an angler to tie a true barrel
knot with ease and thus encourage him to become proficient in one
of the more neglected skills of angling.
It is therefore an important object of the invention to provide a
knot-tying device for use in tying true barrel knots between lines
and can accommodate a wide variety of line weights.
Another object of the invention is to provide a compact, portable
knot-tying device which is exceptionally easy to use in the field
and which enables the tying of a true barrel knot without elaborate
procedures.
Still another object of the invention is to provide a knot-tying
device which is rugged and exceptionally simple in construction and
therefore economical to manufacture.
A further object of the invention is to provide a knot-tying device
in which the structure of the device itself indicates the manner in
which it is to be used so that elaborate procedures need not be
committed to memory and mistakes are avoided.
The above objects, as well as still further objects and advantages,
are attained by the invention which may be described briefly as a
knot-tying device for use in tying a true barrel knot between first
and second lines, the knot-tying device comprising a block, and at
least four releasable retaining means on the block located at each
of four corners of a polygon having at least four sides, each of
the four retaining means being oriented such that a length of one
or the other of the first and second lines will be releasably
retained therein with the line extending transverse to the plane of
the polygon, at least two of the retaining means being resiliently
releasable and facing one another such that the length of line
retained therein will be released therefrom in response to lateral
movement of the retained lengths toward one another.
The invention will be more fully understood, while still further
objects and advantages will become apparent, in the following
detailed description of preferred embodiments of the invention
illustrated in the accompanying drawing, in which:

FIG. 9 is a side elevational view taken in the direction of the
arrow in FIG. 6;
FIG. 10 is a plan view of the knot-tying device of FIG. 6
illustrating its use in the construction of a barrel knot;
FIG. 11 is a front elevational view of another embodiment of the
invention illustrating another alternate knot-tying device
constructed in accordance with the invention;
FIG. 12 is a side elevational view taken in the direction of the
arrow in FIG. 11;
FIG. 13 is a side elevational view taken in the direction of the
arrow in FIG. 11; and
FIG. 14 is a side elevational view similar to FIG. 13 but
illustrating the use of the knot-tying device in constructing a
barrel knot.
Referring now to the drawing, and especially to FIG. 1 thereof, a
typical barrel knot is illustrated at 10. Barrel knot 10 joins
together two consecutive lines 12 and 14. Line 12 is coiled around
line 14 and makes three turns to establish a first helix 16.
Likewise, line 14 is coiled around line 12 and makes three turns
around that line to establish a second helix 18. The end portions
20 and 22 of the lines 12 and 14, respectively, are threaded
between the helixes 16 and 18 in opposite transverse directions
such that when the knot is drawn tight the end portions 20 and 22
are firmly gripped between the confronting helixes 16 and 18 and
emerge from the knot in opposite transverse directions. Thus,
barrel knot 10 is a true barrel knot in that the end portions 20
and 22 of the lines 12 and 14 emerge from the knot in opposite
directions. These opposite end portions 20 and 22 may be cut off
very close to the helixes 16 and 18 so that the barrel knot 10
presents a relatively smooth contour along the length of the knot.
A true barrel knot is preferred since the knot presents a
symmetrical configuration which enhances the desired smooth
contour.
Turning now to FIGS. 2, 3 and 4, a knot-tying device constructed in
accordance with the invention is illustrated generally at 30 and is
seen to include a block in the form of a bar 32, which in this
instance is a parallelepiped, having front and rear portions in the
form of front and rear surface 34 and 36, respectively, extending
between opposite ends 38 and 40, and opposite side portions in the
form of side surfaces 42 and 44, also extending between the
opposite ends 38 and 40. Four resiliently releasable retaining
means are provided in the form of spring clips 46, 48, 50 and 52,
each located at one of four corners of the bar 32, the four corners
representing four corners of a polygon of four sides as viewed in
either FIG. 3 or FIG. 4. The spring clips each include a leaf
spring 54 affixed to the bar 32 by fastener means, illustrated in
the form of rivets 56, such that each leaf spring 54 is held firmly
against a corresponding front and rear surface 34 or 36. Thus, each
leaf spring 54 cooperates with its corresponding surface 34 or 36
to form a spring clip 46, 48, 50 or 52 with the leaf spring 54
serving as one jaw of the clip. Each leaf spring 54 is raised from
its corresponding surface 34 or 36 at the tip 58 of the leaf spring
54 to provide an opening 60 into the jaws of the spring clip. Each
side surface 42 and 44 of the bar 32 is provided with a direction
indicating means, here shown in the form of notches 62 and 64, one
in each side surface, the notches 62 and 64 both having an
arrowhead configuration such that one notch 62 is a pointer which
points toward the front surface 34 of the bar while the other notch
64 is a pointer which points toward the rear surface 36 of the
bar.
Referring now to FIGS. 2 and 5, the knot-tying device is used for
the construction of a barrel knot as follows: The first line 12 is
placed in the opening 60 beneath the leaf spring 54 of the first
spring clip 46 and is moved laterally until the line 12 is held in
place by the leaf spring 54 against the bar 32 at a location spaced
from the terminal end 66 of the line. Likewise, the second line 14
is placed in the opening 60 beneath the leaf spring 54 of the
second spring clip 48 and is moved laterally until the second line
14 is held between the leaf spring of the second spring clip 48 and
the front surface 34 of the bar 32 at a location spaced from the
terminal end 68 of the second line, both lines 12 and 14 then being
held parallel as seen in FIG. 2. Then, the end portion 20 of the
first line 12 is wrapped around the opposite portion 70 of the
second line 14 through a plurality of turns 72 which will establish
the coils of the first helix 16 of the barrel knot 10. The number
of turns 72 is a matter of choice, but three turns are usually
adequate and three turns 72 are illustrated. Upon completion of the
wrapping to establish the desired number of turns 72, the terminal
end 66 of the first line 12 is then threaded through the loop 74
formed between the first and second lines adjacent the side surface
42 of the bar 32. The direction of such threading is indicated by
the direction-indicating notch 62; hence, the terminal end 66 of
the first line 12 is threaded from below the loop 74, as seen in
FIG. 5 upwardly through the loop. After the terminal end 66 is
threaded through the loop 74, the first line 12 is anchored near
its terminal end by placing the first line between the leaf spring
54 of third spring clip 50 and the corresponding portion of the
rear surface 36.
Now, the end portion 22 of the second line 14 may be wrapped around
the opposite portion 80 of the first line 14 in a manner similar to
that in which the first line was wrapped around the second line.
Upon completion of the desired number of turns 82, the terminal end
68 of the second line is threaded through the loop 84 formed by the
first and second lines adjacent the other side surface 44 of the
bar 32, the direction of threading being indicated by the
direction-indicating notch 64. Hence, the terminal end 68 of the
second line is threaded in a direction extending from the front
surface 34 toward the rear surface 36 and is then placed between
the leaf spring 54 of the fourth spring clip 52 and the
corresponding portion of the rear surface 36 where the second line
14 is anchored adjacent the terminal end 68 thereof.
Now, the first and second lines 12 and 14 may be pulled in opposite
directions as indicated by the arrows in FIG. 5. Since the first
and second spring clips 46 and 48 are arranged so that the openings
60 thereto face one another, the pulling of the two lines will draw
the knot tight and simultaneously draw the two lines laterally
toward one another to close the loops 74 and 84 and pull the lines
from beneath their respective spring clips 46 and 48. Continued
pulling of the lines will tighten the knot to establish the two
confronting helixes 16 and 18 and to clamp the end portions 20 and
22 of the two lines between the confronting helixes. Since the end
portion 20 and 22 have been threaded in prescribed directions, the
end portions will project from the knot 10 in opposite directions.
These end portions 20 and 22 may then be released from the spring
clips 50 and 52 and cut off close to the helixes 16 and 18 to
complete a smooth contoured symmetrical barrel knot.
Turning now to FIGS. 6 through 9, another embodiment of the
invention is illustrated in the form of a knot-tying device 100
constructed in accordance with the invention. Knot-tying device 100
also includes a block shown in the form of a bar 102, also a
parallelepiped, having opposite parallel front and rear surfaces
104 and 106 extending between opposite ends 108 and 109 of the bar
and opposite side surfaces 110 and 112, also extending between the
opposite ends 108 and 109.
A first coil spring 114 is located in a groove 116 in one end 108
of the bar and includes first and second arms 118 and 120,
respectively. The first arm 118 includes a first portion 122 which
extends along the rear surface 106 of the bar 102, a second portion
124 which passes transversely through the bar 102 and a third
portion 126 which terminates in a finger 128 resting against the
front surface 104 of the bar 102. The second arm 120 also extends
from one end toward the other end of the bar 102 and includes a
first portion 130 spaced from the front surface 104 of the bar, a
second portion 132 passing through the bar and a third portion 134
terminating in a finger 136 held against the rear surface 106 of
the bar 102.
A second coil spring 140 is located in a groove 142 in the opposite
end 109 of the bar 102 and also includes first and second arms 144
and 146 extending from that end of the bar toward the opposite end
108 of the bar. The first arm 144 includes a first portion 148
which extends along the rear surface 106 of the bar 102, a second
portion 150 passing through the bar and a third portion 152
terminating in a finger 154 resting against the front surface 104
of the bar. The second arm 146 includes a first portion 156 spaced
from the front surface 104 of the bar 102, a second portion 158
extending through the bar and a third portion 160 terminating in a
finger 162 resting against the rear surface 106 of the bar. Each of
the fingers 128, 136, 154 and 162 serves as a jaw of a spring clip
so that here too the knot-tying device 100 is provided with four
resiliently releasable retaining means located at four corners of a
polygon of four sides. As best seen in FIG. 7, each finger 128 and
154 may be lifted from the front surface 104 by pushing the coil
spring 114 or 140 toward the rear, as illustrated in 164 in FIG. 7.
Each finger 136 and 162 may be lifted from the rear surface 106 of
the bar 102 by pushing upon the second arm 120 or 146 of each coil
spring 114 or 140 as illustrated at 166 in FIG. 7.
As in the earlier described embodiment, direction indicating means
are provided in the form of notches 168 and 170 in each of the side
surfaces 110 and 112, the notches having the configuration of a
pointer with notch 168 pointing toward the front surface 104 and
notch 170 pointing toward the rear surface 106 of the bar 102.
Turning now to FIG. 10, the knot-tying device 100 is used to
construct a barrel knot in much the same manner as the earlier
described embodiment of FIGS. 2 through 5. The first and second
lines 12 and 14 are first placed beneath the corresponding fingers
128 and 154 of the coil springs 114 and 140, respectively, and held
in place against the front surface 104. The end portion 20 of the
first line 12 is then wrapped around the corresponding parallel
portion 70 of the second line 14 to establish three turns 72 and is
then threaded through the loop 74 in the direction indicated by the
notch 168. Subsequently, the end portion 20 is placed beneath the
finger 162 of the coil spring 140 to anchor the end portion against
the rear surface 106 of the bar 102. Likewise, the end portion 22
of the second line 14 is wrapped around the corresponding parallel
portion 80 of the first line 12 to establish three turns 82 and is
then threaded through the loop 84 in the direction indicated by the
notch 170. The end portion 22 is then anchored beneath the finger
134 of the coil spring 114 against the rear surface 106 of the bar
102. It is noted that the relationship between the fingers of a
single coil spring is such that movement of either one finger away
from its corresponding surface will tend to urge the other finger
toward its corresponding surface so that when each coil spring is
actuated to move the finger away from the rear surface as the end
portion of a line is anchored to the rear surface, the portion of
the line which is clamped between the other finger and the front
surface is held with a greater clamping force, thus tending to
retain that line in place.
Upon pulling the lines 12 and 14 in opposite directions, as
indicated by the arrows in FIG. 10, the portions of the lines
forming the loops 74 and 84 will be moved laterally toward one
another and will be released from beneath their respective fingers
128 and 154 to enable the knot to tighten and to establish the
confronting helixes 16 and 18. The end portions 20 and 22 of the
lines, having been threaded through the loops 74 and 84 in a
prescribed direction will be clamped between the confronting
helixes 16 and 18 and will project from the knot 10 in opposite
directions, as before.
Referring now to FIGS. 11, 12 and 13, still another embodiment of
the invention is illustrated in the form of knot-tying device 200
which includes a block with a composite construction including a
body of resilient elastomeric material, such as rubber, shown in
the form of a core 202 sandwiched between a pair of side plates 204
and 206 which are held together by fastening means shown in the
form of rivets 208. The block is generally parallelepipedal and
includes front and rear portions in the form of front and rear
edges 210 and 212 extending between opposite ends 214 and 216 and
opposite side portions in the form of side surfaces 218 and 220
also extending between the opposite ends. The core 202 of the block
is provided with a notch 222 adjacent the front edge 210 of the
block intermediate the opposite ends 214 and 216 and terminating at
a forward-facing surface 224 on the core 202. A first resiliently
releasable retaining means is provided by a slit 226 in the core
extending from the notch 222 toward one end 214 of the block while
a second resiliently releasable retaining means is provided by a
second slit 228 extending from the notch 222 in an opposite
direction toward the opposite end 216 of the block. Third and
fourth resiliently releasable retaining means are provided adjacent
the rear edge 212 of the block by third and fourth slits 230 and
232 in the core 202 adjacent the rear edge of the block. The
configuration of the side plates 204 and 206 is such that the slits
226, 228, 230 and 232 are exposed for the reception of the first
and second lines 12 and 14 as will be described hereinafter.
Direction indicating means are provided in each of the side surface
in the form of directional arrows or pointers 234 and 236,
respectively, etched, scored or otherwise permanently displayed in
the side plates 204 and 206 as shown in FIGS. 12 and 13.
Referring now to FIG. 14, knot-tying device 200 is employed in
constructing a true barrel knot in a manner similar to that
described in connection with the earlier embodiments. The first
line 12 is inserted into the first slit 226 and is held at a
location spaced from the terminal end 66 of the first line 12 by
the resilient grip of the elastomeric material of the core 202.
Likewise, the second line 14 is placed within the second slit 228.
The end portion 20 of the first line 12 is then wrapped around the
corresponding parallel portion 70 of the second line 14 to
establish three turns 72 and is then threaded through the loop 74
in the direction indicated by the pointers 234. The first line 12
is then anchored adjacent its terminal end 66 within the third slit
230. The end portion 22 of the second line 14 is then wrapped
around the corresponding parallel portion 80 of the first line 12
to establish three turns 82 and is then threaded through the loop
84 in the direction indicated by the pointers 236 in the side plate
206. The second line 14 is then anchored adjacent its terminal end
68 in the fourth slit 232.
Upon pulling the lines 12 and 14 in opposite directions, as
indicated by the arrows in FIG. 14, the portions of the first and
second lines which form the loops 74 and 84 will move laterally and
will be released from the first and second slits 226 and 228 while
the respective turns 72 and 82 will be tightened to establish the
confronting helixes 16 and 18. Continued pulling on the lines will
clamp the end portions 20 and 22 of the lines between the
confronting helixes 16 and 18 to complete the barrel knot 10 with
the end portions projecting from the knot in opposite directions.
The end portions 20 and 22 may then be removed from their
respective slits 230 and 232 and cut off to complete a
smooth-contoured, symmetrical barrel knot.
It will be seen that each of the above described embodiments is
exceptionally simple in construction and may be fabricated of
corrosion resistant materials for long and dependable service.
Elaborate procedures are not required in order to construct a true
barrel knot and those procedures which must be performed need not
be committed to memory since the manner in which the devices will
be used is indicated on the device by the direction indicating
means. Each device is capable of handling a wide range of line
weights.
It is to be understood that the above detailed description of
preferred embodiments of the invention is provided by way of
example only. Various details of design and construction may be
modified without departing from the true spirit and scope of the
invention as set forth in the appended claims.
