loom and for transporting a plurality of said removed said filled
cloth rolls away from the loom area. A doffing cart is provided
which is adapted to be placed adjacent the horizontally extending
filled cloth roll on the loom and includes means for lifting the
roll, when detached, horizontally onto the cart. The doffing cart
with the filled cloth roll secured thereto may then be lifted to an
upright position, where the filled cloth roll extends vertically,
and the doffing cart may then be rolled away from the loom in the
narrow aisles generally provided between looms. A receiving cart is
provided which is adapted to receive the filled cloth roll from the
doffing cart, store a plurality of said rolls and transport said
plurality of rolls away from the loom area. Further, the receiving
cart may store a number of empty rolls for installation in the
looms when the filled rolls are removed therefrom. The doffing cart
includes a tongue means adapted to be engaged with a coupling bar
on the receiving cart placing the platform which supports the
vertical filled cloth roll on the doffing cart substantially flush
with the floor of the receiving cart so that the filled cloth roll
need only be slid from one cart to the other.

Description
This invention relates to an assembly for removing a filled cloth
roll from a loom, lifting said cloth roll to a vertical position,
transporting said cloth roll away from said loom to a receiving
means and wherein said receiving means is adapted to receive and
store a plurality of said filled cloth rolls and transport same
away from the loom area. In particular, this invention relates to
cart means for transporting a filled cloth roll, said cart means
including means for lifting a detached filled cloth roll onto said
cart and transporting same away from the loom, and in addition, a
cart means for receiving a plurality of the filled cloth rolls from
a doffing cart or carts for transporting the plurality of filled
cloth rolls from the loom area.
It is well known that the filled cloth rolls on looms are very
heavy and bulky making them difficult to manipulate. Further, it is
generally the case that in a loom area a number of looms are placed
very close together so that the aisles provided therebetween for
removing filled rolls and installing empty rolls are quite narrow
making it difficult to manipulate the heavy, bulky filled cloth
rolls therein. At the present time, the filled cloth rolls are
generally removed from the looms manually, and the worker must then
manipulate the roll through the narrow aisle between looms and
carry it to a storage area. In performing this task he is required
to bend or stoop to grasp the filled cloth roll, detach it from the
loom, lift himself and the filled cloth roll to an upright position
and manipulate the heavy, bulky filled cloth roll outwardly from
between the looms in the very narrow aisle provided therefor.
Further, he is often required to carry this very heavy roll a
substantial distance to a storage area. In addition, in removing
the filled cloth roll from the loom it is necessary to install
therein an empty roll so that either the worker removing the filled
roll must also manipulate an empty roll or an additional worker
must be provided to install empty rolls to replace the filled
rolls. It can be seen that the manual labor required in carrying
out this operation is costly and time consuming in addition to
being difficult.
It is therefore an object of this invention to provide a means for
removing filled cloth rolls from looms and transporting same away
from the loom area which will reduce the manual labor involved to a
minimum.
Another object of this invention is to provide a means for
manipulating a filled cloth roll from a loom in a very narrow
area.
A further object of this invention is to provide a means for
lifting the horizontally extending filled cloth roll which has been
detached from a loom onto a cart means, said cart means being
adapted to be raised to a vertical position and moved away from the
loom in the very narrow aisles provided between looms.
Still another object of this invention is to provide means for
transporting a plurality of filled cloth rolls away from the loom
area, said means being adapted to be engaged with the cart means
defined in the object immediately above so that the filled cloth
roll may be removed from the above-described cart means to the
means described herein without requiring manual lifting.
The aforementioned and other objects are provided in any assembly
which comprises a first cart means for receiving and having secured
thereto a horizontally removable cloth roll from a loom and a
second cart means for receiving and storing a plurality of the
filled cloth rolls. The first cart means is adapted to move the
detached horizontally extending filled cloth roll onto said first
cart, raise the cart to a vertical position and transport same
through the narrow aisles between looms. The first cart means
includes movable arms for lifting the filled cloth roll onto the
cart. The second cart means is adapted to receive a plurality of
the filled cloth rolls in the vertical or upright position, and it
also includes a storage area for empty rolls to be used for
replacing the filled rolls on the looms. The first cart includes a
platform upon which an end of the filled cloth roll rests when in
the vertical or upright position and this platform is designed to
be a height corresponding to the height from the loom room floor of
a similar supporting surface on the second cart. A means for
coupling the first cart to the second cart is provided so that the
filled cloth roll may be slid from one to the other without
requiring manual lifting.
The principles of this invention may be best understood by
reference to a description hereinbelow of a preferred embodiment of
an assembly which is constructed and designed to operate according
to said principles in conjunction with the drawings in which:

FIGS. 10a-j are diagrammatic top elevations of the doffing cart
illustrating the manipulations required of the doffing cart to
place the filled cloth roll thereon.
While the assembly constructed according to the principles of this
invention comprises two elements, namely a doffing cart and a
receiving cart, the structural details of these elements will be
described separately hereinbelow.
In FIGS. 1-4 a preferred embodiment of the doffing cart for
directly receiving the filled cloth roll from the loom and having
same secured thereon for transporting the filled cloth roll in the
narrow aisle between looms is described. In these figures as well
as all of the other figures of the drawings like elements are
indicated by like numerals.
The doffing cart, generally indicated by the numeral 10, has a
frame structure comprised of two horizontally spaced elongated
frame members 12a and 12b which are shown in a horizontal position
in FIG. 1 and in the vertical position in FIG. 4. The frame members
12a-b are separated by a cover plate 33 at the top or end of the
cart, and a U-shaped handle 32 is attached between frame members
12a and 12b at this point. An angle bracket 34 attached to the
frame members 12a-b is provided at the end of the cart remote from
cover plate 33. The space between the frame members 12a and 12b is
of a width which will allow the width of a filled cloth roll to be
accommodated therebetween, but which will allow the width of the
doffing cart defined by the distance between said frame members 12a
and b to be accommodated in the narrow aisles usually found between
looms. Depending on the position of the cart, angle bracket 34
extends horizontally or vertically and supports a channel-shaped
platform member 36. As shown in FIG. 1, the cart, particularly
frame members 12a and 12b, is extended horizontally. The platform
36 is equipped with a floor surface 40 which is of a
friction-reducing material; in the preferred embodiment nylon is
used for this purpose, but any similar material achieving the
desired result may be used. The bight portion of channel-shaped
platform 36 which supports floor surface 40 extends forwardly and
outwardly thereof and is bent substantially perpendicularly with
the floor surface 40 to form a tongue 37, the purpose for which
will be discussed more fully hereinbelow. A caster 60 of the
conventional variety is attached to platform 36 by means of wheel
block 62 to support the platform when the cart 10 is in the upright
or vertical position shown in FIG. 4.
A pair of wheels 43 are placed on both sides of angle bracket 34
and rotatably mounted on an axle 42 which is supported from angle
bracket 34 by means not shown. An antiskid lever 45 having a
perpendicularly-related tongue member 47, rotatably mounted on axle
42 axially adjacent one of the wheels 43, is provided for braking
the wheel 43 associated therewith when the cart 10 is in the
horizontal position shown in FIG. 1. That is, when the lever 45 is
placed in a position so that its tongue member 47 is wedged between
the wheel surface with which the lever is associated and the floor,
the wheel will be effectively braked, and the cart 10 may then be
readily lifted or levered into the vertical position shown in FIG.
4 without fear of wheels 43 rolling.
An L-shaped member 38 is attached to angle bracket 34 with an arm
of the L extending parallel to and slightly beneath the frame
members 12, when viewing the cart 10 as in FIG. 1. This member 38
is provided for supporting an empty roll 80 in the manner shown in
FIG. 4 so that such an empty roll is readily available for
installation in a loom after the filled cloth roll is removed. The
empty roll 80 is further secured to the cart 10 by means of handles
46 and 48 attached to frame members 12 substantially at the centers
thereof. The handles 46 and 48 are used also as a means for
manually pushing the cart in the upright position shown in FIG. 4.
The handle 46 is designed to be stationary and is fixedly secured
to frame member 12a. The handle 48, however, is spring loaded so
that the inward portion of the handle may be moved away from frame
member 12b allowing the roll 80 to be removed from the cart. As
best shown in FIG. 3, handle 48 is attached to frame member 12b by
means of a bolt 81 having a compression spring 83 interposed
between the bolt 81 and the nut 82. Thus, the spring 83 tends to
hold handle 48 in against frame member 12b but it may be manually
pushed rearwardly to allow removal of the roll 80.
At a point on frame members 12a and 12b slightly above handles 46
and 48 are attached wheel blocks 26 and 22, respectively, having
rotatably secured thereto wheels 27 and 24, respectively. The
wheels 24 and 27 allow the cart 10 to be readily manipulated by
handle 32 when the cart is in the horizontal position shown in FIG.
1.
A pair of stationary arcuate-shaped arms are spaced along the
length of frame member 12b. These arm members 18 and 20,
respectively, are fixedly attached to frame member 12b by any
well-known means, such as welding, at points 19 and 23. The arm
members 18 and 20 have portions 17 and 21, respectively, along
their arcuate length which extend across the space between frame
members 12a and 12b, as best shown in FIG. 4. The portions 17 and
21 provide support for the filled cloth roll placed on the cart
between frame members 12a and 12b when the cart is in the
horizontal position shown in FIG. 1.
A pair of rotatable, arcuate shaped arms 14 and 16 are spaced along
the length of frame member 12a and are adjacent the arms 18 and 20,
respectively. The arms 14 and 16 are rotatably mounted, in a manner
to be described below, on a pickup rod 30 which is rotatably
mounted on frame member 12a by means of frame bearing blocks 28.
The rod 30 is adapted to be rotated in either a clockwise or
counterclockwise direction. At the end thereof adjacent handle 32,
the rod 30 is bent in substantially a 90.degree. angle to form
pickup rod handle 31, and the end of angle 31 is broken to form a
rotatable portion 29 for manipulating the pickup rod 30. The arm 16
is mounted by any convenient means firmly to the pickup rod 30 so
that this arm will rotate 90.degree. in both directions when the
pickup rod 30 is so rotated. The arm 14 is, however, rotatably
mounted on pickup rod 30 in such a way that the arm 14 will not
follow pickup rod 30 when it is rotated in a clockwise direction,
but it may be freely manually rotated in that direction about the
rod, said direction being taken as it would appear to one facing
handle 32 and the length of the cart. The arm 14 is attached to the
pickup rod 30 by a positive drive mechanism 72 so that when the
handle 30 is rotated in the counterclockwise direction the arm 14
will follow the motion of the pickup rod. It is to be noted that
when the arms 14 and 16 are at rest in the fully counterclockwise
position, they extend upwardly from a horizontally placed cart 10
in a manner similar to arms 18 and 20. When the arms 14 and 16 are
rotated fully in the clockwise direction they extend outwardly,
laterally of frame member 12a.
An angle bracket 62 is mounted on wheel block 22 and has attached
to the upwardly extending portion thereof strap 64, which is made
of rubber in the preferred embodiment, and which is adapted to
secure the filled cloth roll on the cart. The strap 64 extends
across the width of the cart between frame members 12a and 12b and
has at its end an eyelet 66 adapted to be placed around a peg 68
attached to an angle bracket 67 extending upwardly from wheel block
26.
The frame members, arms, angle brackets, handles and the like
described hereinabove are all preferably fabricated in the
well-known manner from lightweight metallic materials to enhance
the ease of manipulation of the cart.
In order to more clearly understand the functions of the various
movable parts, particularly the arms 14 and 16, on the doffing cart
10 and in order to more clearly understand how doffing cart 10 is
used to remove a filled cloth roll from a loom reference will now
be made to FIGS. 10a-j which are diagrammatic illustrations of the
various positions of the cart and the arms illustrating the use of
the cart for filled cloth roll removal. In each of these Figures
like elements are indicated by like numerals and correspond to
numerals used in FIGS. 1-4. In FIG. 10a the doffing cart 10 is
shown as having been placed in the narrow aisle between looms 92a
and 92b. The doffing cart is in the horizontal position as shown in
FIG. 1, and it will be used to remove a filled cloth roll 90 from
loom 92a. In this position doffing cart 10 is manipulated by
operator 88 at the handle of the doffing cart 32 to be placed under
the loom 92a as close to the roll of cloth 90 as possible. It is to
be noted that an empty roll 84 is in place on the doffing cart 10,
as shown in FIG. 4.
In FIG. 10b the doffing cart 10 has been manipulated by the
operator so that the end thereof adjacent platform 36 is under loom
92a and under and end of filled cloth roll 90.
FIG. 10c illustrates the doffing cart 10 as being in the same
position as in FIG. 10b, but at this point the operator has turned
handle 31 and pickup rod 30 through an angle of 90.degree. in a
clockwise direction, the direction being as seen by the operator 88
facing handle 32. In so rotating the pickup rod 30 movable arm 16
is rotated so that it is in an outstretched position extending
laterally from cart 10 beneath roll 90. The movable arm 14, because
of the mode of connection described above, will remain in an
upright position.
FIG. 10d illustrates arm 16 of doffing cart 10 being in the same
position as in FIG. 10c. In this figure, however, the operator has
moved the doffing cart inwardly under loom 92a so that the arm 16
is more fully under the filled cloth roll 90. It is to be noted, as
mentioned above, that the doffing cart 10 is made of very light
weight materials so that it can readily be moved under the loom by
means of manipulation of handle 32.
FIG. 10e illustrates the doffing cart 10 being in the same position
as in FIG. 10d, but in this figure the operator has manually
rotated movable arm 14 through an angle of substantially 90.degree.
in a clockwise direction so that arm 14 is directly underneath the
end of cloth roll 90 remote from the end beneath which arm 16 has
been placed.
FIG. 10f illustrates the arms 14 and 16 of doffing cart 10 as being
in the same position as in FIG. 10e. In this figure, however, the
end of doffing cart 10 adjacent arm 14 is moved by the operator so
that it is beneath roll 90 to a greater degree.
When the doffing cart 10 is under the roll 90 in the manner shown
in FIG. 10g so that both the arms 14 and 16 and a substantial
portion of the width of the cart are beneath the roll 90, the
operator may then disengage the end of roll 90 adjacent arm 14 from
the loom. The end of roll 90 adjacent arm 14 is then allowed to
merely drop down onto cart 10 so that it rests on arm 14. The end
of roll 90 adjacent arm 16 remains engaged to the loom.
In FIG. 10h the end of roll 90 adjacent arm 14 is shown as resting
on the arm, and the cart 10 has been moved so the end of the cart
adjacent handle 32 is pulled outwardly away from the loom. That is,
the cart is manipulated to be at an angle with the loom so that
only that end of the roll resting an arm 14 is brought out from
under the loom.
As shown in FIG. 10i, with an end of the filled cloth roll 90
resting on arm 14, the operator will pull the cart and cloth roll
toward him, and the end of the cloth roll adjacent arm 16 will be
disengaged from the loom by this pulling action and will fall onto
arm 16. While the cloth roll 90 is resting on arms 14 and 16, the
doffing cart 10 should be manipulated so that it is entirely out
from under the loom 92a.
In FIG. 10j the arms 14 and 16 have been rotated in a
counterclockwise direction by rotating handle 31 of pickup rod 30.
The movement of arms 14 and 16 in the above-described manner moves
the roll onto the doffing cart 10 so that it rests thereon on
portions 17 and 21 of fixed arms 18 and 20, respectively (see FIG.
4). The fixed arms 18 and 20, while roll 90 is being moved by arms
14 and 16, act as barriers preventing the filled cloth roll 90 from
rolling off doffing cart 10 on the side thereof away from the loom
from which the filled roll was removed. When the filled cloth roll
90 is resting on doffing cart 10, the holding strap 64 may be
placed across the roll and attached to the pin 68 thereby firmly
securing the roll to the cart.
With antiskid lever 45 in place so that tongue 47 thereof is wedged
between wheel 43 and the floor upon which the cart is resting the
doffing cart may be lifted or levered into an upright position,
this position being shown in FIG. 4. With the cart in this position
an end of filled cloth roll 90 will rest on the floor surface 40 of
channel-shaped platform 36. Any tendency of the roll to fall
forwardly is resisted by the attached strap 64. Having lifted the
doffing cart 10 to its upright position with the filled cloth roll
secured thereon the operator may then remove the empty roll 84 from
its place on the cart on roll support 38 by pulling handle 48
rearwardly and install the empty roll 84 in the loom.
FIGS. 5 and 6 illustrate, in end and top elevations, respectively,
the structural details of a first preferred embodiment of a
receiving cart constricted according to the principles of this
invention. In these two figures like elements are indicated by like
numerals.
The receiving cart, generally indicated as 100, is adapted to
receive a plurality of filled cloth rolls from the doffing cart 10
in a manner to be described hereinbelow and to store said filled
cloth rolls in a vertical or upright position. Further, along the
rear side thereof, the receiving cart 100 is adapted to store a
number of empty rolls for installation on the looms from which
filled cloth rolls have been removed.
The receiving cart 100 includes floor braces 101 upon which a
surface 102 has been placed. Beneath floor surface 102 and
centrally disposed on the front and rear sides of the cart 100
wheel blocks 108 have been mounted from which depend the wheels
107. Centrally of the ends of the cart, casters 109 have been
mounted allowing the cart to be readily maneuverable. A truck lock
132 is mounted at one end of the receiving cart 100 and is operable
by a handle 133 to lock the cart in place, as needed. Rubber
bumpers 104 are mounted on the four corners of the cart as formed
by the floor brace members 101. A coupling bar 106 is mounted along
the front side edge of the floor 102 of the cart. This bar is
fixedly attached to that edge and is extended outwardly therefrom
by spacers 107. The function of coupling bar 106 will be discussed
more fully hereinbelow.
In order to store the filled cloth rolls, as well as the empty
rolls, in an upright position an upright frame structure is
provided which extends around the periphery of the cart 100, but is
open at the front side thereof adjacent coupling bar 106 to allow
filled rolls to be placed in the cart. This frame structure is
formed by a pair of upright members 112 placed at the front corners
of the cart adjacent coupling bar 106. An additional front upright
member 112 is centrally placed along the front side of the cart 100
to divide same into two sections. Rear upright members 114 are
placed along the rear edge of the cart in positions corresponding
to the positioning of the front upright members 112. The front
upright members 112 are interconnected with the corresponding rear
upright members 114 by means of top cross members 110 which extend
between the top ends of the aforementioned upright members. In
addition the rear upright members 114 support a rear barrier frame
structure generally indicated as 122. A second barrier structure
120 is placed inwardly from rear barrier structure 122 by means of
brace 144. As best shown in FIG. 5, the ends of the receiving cart
are open to allow the empty rolls 140 to be readily removed from or
placed in the space defined between barrier structures 120 and 122.
Additional cross members 116, 118 and 130 are provided for
additional lateral structure support between upright members 112
and 114. Again, it must be remembered that there is no frame
structure extending between the upright members 112 allowing the
front portion of the receiving cart to remain open for placing
filled cloth rolls therein.
In order to understand how a doffing cart 10 will cooperate with
receiving cart 100 in order to transfer the filled cloth roll from
the doffing cart to the receiving cart a portion of a doffing cart
is shown in dotted line in FIG. 6 and indicated with the numeral
10. It will be remembered from the description of the structural
details of the doffing cart 10 in FIGS. 1-4 that the bight portion
of the channel-shaped platform 36 extended forwardly from the
remainder of the platform then was bent downwardly to form a tongue
37. When a filled cloth roll has been placed on doffing cart 10 and
the cart levered into the upright position shown in FIG. 4, the
doffing cart 10 may be pushed by means of handles 46 and 48 to the
position of the receiving cart 100. The turned-down tongue 37 of
doffing cart 10 will fit in the space between coupling bar 106 and
the front side floor brace member 101 on cart 100. The floor
portion 40 of platform 46 on doffing cart 10 is sloped slightly
forwardly toward tongue 37, and the floor surface 102 in cart 100
also slopes slightly downwardly rearwardly away from coupling bar
106. Further, these floor surfaces are made of friction resistant
material so that the filled cloth roll may be readily slid in the
vertical position from cart 10 to cart 100. The wheel structure of
cart 10 is designed so that the floor surface of platform member 36
will be of a height from the floor substantially equal to the
height of the floor surface in the cart 100 from the loom room
floor. Further, in coupling the doffing cart to the receiving cart
the floor surface 40 will be placed substantially flush with the
floor surface 102 by means of a coupling action of tongue 37 and
coupling bar 106.
As the receiving cart 100 is filled with cloth rolls, it may be
manually moved from position to position ad desired by means of
handles 126 placed on each of the opposing ends thereof. The truck
lock 132 will allow the cart 100 to be locked in a given position
by means of a foot operation of handle 133 in the well-known
manner.
FIGS. 7 and 8 illustrate the structural details of a second
preferred embodiment of a receiving cart adapted to receive filled
cloth rolls from a doffing cart 10. The receiving cart 200 is
adapted to have the filled cloth roll 90 loaded therein from either
side thereof. Means are provided for having a plurality of empty
rolls 140 stored centrally in the cart in horizontally extending
positions and in a vertically stacked relationship.
The cart 100 includes a floor formed by support members 202 and a
surface member 204. Wheels 208 are attached in any well-known
manner to the four corners of the cart 200 allowing it to move
along the area where it is to receive filled cloth rolls. The cart
200 is designed to be drawn by motive power, e.g., a power truck,
so that eyelets 210 are provided on both ends of the cart and are
attached to the floor support member 202.
The end frame structures of the cart 200 are formed by continuous,
U-shaped members 214 placed at both ends of the cart. The ends of
the U in each member 214 are attached to opposite front and rear
corners at a given end of the floor structure 202. Three front
upright members 216 are spaced along the length of the cart 200
substantially centrally of its width, two of the members 216 being
adjacent, attached to and providing vertical support for end
members 214 and the other of the members 216 being located
centrally along the length of the cart. Three rear upright members
218 are placed in corresponding positions along the length of the
cart, but they are spaced from members 216 a distance slightly
greater than the width of an empty roll 140. The upright members
216 are interconnected laterally by at least one cross member 220
which also provides lateral support for the end members 214. The
upright members 218 are interconnected by a cross member 221.
Within and across the space between uprights 216 and 218 shelf
members 222 are attached. These members 222 may have an arcuate
shape to accommodate the empty rolls 140, and they are placed above
one another a height to allow the empty rolls to be accommodated.
Thus, as best shown in FIG. 8, the empty rolls 140 may be readily
slid in and out horizontally from the ends of cart 200.
As discussed hereinabove, the filled cloth rolls 90 are stored on
either side of the cart 200 and may be placed therein from either
side, as shown in FIG. 7. A number of pairs of straps 224, attached
to cross members 220 and 221 are provided for the filled cloth
rolls, one pair fitting around each roll. The straps 224 are
attached to each of the cross braces 220 and 221 by plates 226
which are bolted thereon. An end of one of the straps of each pair
224 is equipped with an eyelet 225, and an end of the other strap
of each pair is equipped with a hook 227 so that a pair of the
straps 224 may be secured around the filled cloth roll 90.
Referring to FIG. 9, in order to move a filled cloth roll 90 from a
doffing cart 10 to the receiving cart 200 the tongue 37 of the
doffing cart 10 is placed in the space between the coupling bar
212, which is bolted to and spaced the appropriate distance, as
determined by the thickness of tongue 37, from floor member 202.
This places the surface 40 in the doffing cart 10 substantially
adjacent the floor surface 204 in the receiving cart 200 so that
the filled cloth roll 90 may readily be slid therein. When the
filled cloth roll 90 has been placed in the receiving cart 200 it
is secured therein by means of straps 224.
It may be seen from the description of the preferred embodiments
given hereinabove that the objects set forth above may readily be
achieved by utilizing the invention defined herein by the claims.
In addition it is to be remembered that the description of the
preferred embodiments given hereinabove is only exemplary and that
modifications may be made to the described structural elements or
their structural arrangement within the scope of the appended
claims.
