Improvements in Machines for Winding or Beaming Yarns.
I, DAVID MCTAGGART, of 91, Exchange Street, Worcester, in the County of
Worcester and State of Massachusetts, United States of America, Manufacturer,
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:-
C
My improvements relate to an apparatus designed to apply pressure upon a
warp as it being wound upon a warp beam, whereby the yarn is wound more
tightly and solidly upon the beam, thereby increasing the amount of the warp
upon the beam and rendering its tension more uniform during the process of
weaving.
In the following description of my invention and the manner in which the
same is to be performed, reference is made, by reference letters and figures, to
the accompanying drawings which represent an apparatus for embodying my
invention compressing the yarn as it is wound upon the warp beam, showing
the manner of putting my invention into practice and forming a part of this
specification.
Figure 1 represents a warp beam and a warp compressing apparatus embody-
ing my invention by which pressure is applied to the yarn as it is wound upon
the warp beam, the mechanism by which the warp beam is rotated having been
omitted. The pressure-roll of the compressing apparatus is shown in Figure 1
as resting upon the barrel of the warp beam in proper position to apply, pressure
to the yarn as it is being wound upon the beam.
Figure 2 represents the warp beam and compressing apparatus shown in
Figure 1 with the warp compressing apparatus shown in an elevated position
in order to raise the pressure-roll away from the warp beam and allow free
access thereto.
Figure 3 is a transverse sectional view of the pressure-roll and. central
hooked arm of the framework by which the pressure-roll is supported, said
section being taken on a vertical plane passing through the center of said central
hooked arm.
Figures 4 and 5 represent portions of the apparatus for supporting the pres-
sure-roll, showing the mechanism by which the gravity of a suspended weight
is applied to rock the framework supporting the pressure-roll and apply pressure
to the yarn as it is wound upon the warp beam.
Figure 6 is a top view of one of the floor plates and the stands by which one
end of the warp beam and warp compressing apparatus is supported, said stands
being shown in sectional view on line 6, 6, Figure 1.
Figure 7 is a top view of one of the floor plates.
Figure 8 is a central longitudinal sectional view of the pressure-roll.
Figures 9 to 16, inclusive, represent different views of a pressure-roll showing
a modified construction.

Like letters and figures of reference indicate like parts in the accompanying
drawings.
Referring to the drawings, 1 denotes the barrel of a warp beam having
heads 2, 2 journalled at opposite ends in duplicate supporting stands, one of
which is shown at 3, Figures 1 and 2, in which the warp beam, in the operation
of winding the warp, is slowly rotated by any of the well known driving
mechanisms now used for that purpose by which the warp threads are drawn
from either a reel or a series of spools and wound upon the barrel 1 and between
the heads 2, 2 in the usual and well known manner.
At one side of the warp beam is a rocking bar 4 journalled at each end in
sleeves 5,5 pivotally connected by bolts G to the forked ends of spindles 7 which
are journalled in supporting stands 8 and are provided with a screw 9 engaging a
screw thread in the stand, thereby allowing the bearings of the rocking bar 4 to
be vertically varied to bring the axis into the proper relative position to the axis
of the warp beam.
The stands 3 and 8 at each end of the apparatus are supported upon a common
floor plate 10 attached to the floor by bolts 11 and having upon its upper surface
lugs 12 provided with dove-tailed openings between them to receive the dove-
tailed feet 13 of the stand 3. The floor plate 10 is also provided with lugs 14
having dove-tailed openings between them to receive the dove-tailed feet 15
of the stand 8; but having the openings between the lugs. 12 tapered oppositely
to that of the lugs 14, so that as the stands 3 and 8 are drawn together their
feet 13 and 15 will be tightly wedged between the lugs and firmly attached to
the floor plate 10. The stand 3 is provided with a projecting arm 16 which is
arranged to strike against the stand 8 when the dove-tailed feet of the stands
have been drawn tightly between the lugs. Pivoted to the stand 3 is a bar 17
which passes through a mortise 18 in the stand 8 and is provided with a hole
to receive a wedge 19 by which the stands are drawn together until the arm 16
is brought into contact with the stand 8. The floor plates at opposite ends of
the apparatus are duplicates and maintain the stands of the warp beam and
rocking bar 4 in their proper relation to each other while the method of attach-
ing the stands to the floor plates allows them to be detached and those of
different heights substituted when required.
Attached to the rocking bar 4 are parallel arms 20, 20 and a central arm 21
extending over the barrel of the warp beam. Each of the arms 20, 21 are pro-
vided with hooked ends 22 inclosing about two-thirds of the periphery of a
pressure-roll 23 which is inserted endwise within the hooked ends of the arms
and is of suitable length to enter between the heads of the warp beam and rest
upon the yarn as it is wound upon the barrel 1 of the beam.
The hooked ends 22 of each of the arms 20, 21 are recessed at 24 to receive the
friction pulleys 25 which turn upon pins held in the arms and bear against the
periphery of the pressure-roll 23, in order to reduce the friction upon the
pressure-roll and permit it to turn within the hooked ends of the arms by its
frictional contact with the varn as the beam is rotated.
Above the central arm 21 is a bar 26, journalled at one end in an arm 27, pro-
jecting upwardly from the hooked end of the central arm 21 and at the opposite
end in a bracket 28 attached to the rocking bar 4. The edges of the bar 26
form ways for a sliding block 29 which is traversed along the bar 26 by means

page_text: of a rotating screw 30 journalled concentrically within the ends of the bar 26 and
connected with the sliding block 29 by means of a screw or pin 31 held in
the sliding block 29 and engaging the threads of the screw 30. The sliding
block 29 is provided with friction pulleys 32 bearing against the lower edge of
the bar 26 and the upper end of the sliding block 29 carries a scored pulley 33.
Suspended from the ceiling above the apparatus is a pulley block 34 containing
a scored pulley 35 and a pulley block 36 containing the scored pulleys 37 and 38.
A weight 39 is attached to one end of a chain, or cable 40 which passes over
the pulleys 35, 37, 33 and 38, in the order named, and also around a pulley 41
in a pulley block 42 to an eye-bolt 43 to which the opposite end of the cable 40
is attached. The pulley block 42 is connected by a chain, or cable, 44 to one
end of a lever 45 pivoted at its opposite end upon the bracket 28.
The weight 39 exerts an upward pulling strain upon the sliding block 29 and
when the sliding block 29 is moved along the transverse bar 26 by the actuating
screw 30, so that the pull exerted by the weight 39 is applied in a plane between
the axis of the rocking bar 4 and the pressure roll 23, it will tend to raise the
pressure-roll off the warp; but if the sliding block 29 is moved along the trans-
verse bar 26 to the rear of the rocking shaft, the upward pull exerted by the
weight 39 will tend to rock the bar 4 in the opposite direction and carry the
pressure roll 23 down upon the yarn as it is being wound upon the barrel 1.
The continuous chain, or cable, 40, as it passes around the scored pulleys, is
divided by the pulleys 33, 37, 38 and 41 into sections a, b, c and d, and the
sections b and c are connected by a short chain or cable 46.
When the sliding
block 29 is moved forward over the rocking bar 4, as represented in Fig. 4, the
weight 39 will raise the pulley block 42 and lever 45 until the connecting chain
46 is drawn taut, as shown in Figure 4, thereby connecting the sections b and c,
cutting out the section d and that portion of the section below the connecting
chain 46 and causing the entire lifting strain to be applied to the sliding
block 29. Whenever the sliding block 29 is moved back, as represented in
Figure 5, its lower end strikes the cam surface 47 of the lever 45, causing the
lever 45 to be depressed and draw down the pulley block 42, thereby slackening
the connecting chain 46, so that the force of the weight 39 will be exerted upon
the sliding block 29 through the sections a, b, c and of the chain 40, thereby
multiplying the force applied to rock the bar 4 and carry the pressure roll 23
against the warp.
1
By the above described method of applying the weight 39 the force exerted
upon the sliding block 29 is reduced whenever the sliding block 29 is moved off
the lever 45 and when it is not desired to apply pressure to the warp; but the
force of the weight 39 is increased by moving the sliding block 29 backward
over the lever 45 when it is desired to apply pressure to the warp.
The rocking bar 4 is capable of being moved endwise in the sleeves 5, 5, in
order to bring the hooked arms 20, 21 in proper position between the heads of
the warp beam, and it is adjustably held by means of pins 48 and a series of
holes 49.
When it is desired to raise the pressure-roll, in order to allow access to the
warp beam, the sliding block 29 is moved along the transverse bar 26, over the
rocking bar 4, so that the weight 39 will balance the weight of the pressure-roll
and its supporting framework. The bolt 6 is then withdrawn from one of the
sleeves 5 and the sliding block 29 moved to the forward end of the bar 26 causing
the released end of the rocking har 4 to be raised from its supporting stand
while the opposite end is supported in its sleeve 5 which rocks upon the 'pin 6
in the forked end of the supporting spindle 7, thereby bringing the pressure-roll
into an oblique position, as represented in Figure 2.
When the pressure roll is raised in the oblique position, as represented in
Figure 2, it is prevented from sliding endwise in the hooked arms 20, 21 by
means of latches which consist of bars 50 pivoted at one end to the outer sides
of the arms 20 and carrying at their opposite ends rods 51 to which are

page_text: adjustably attached blocks 52 adapted to overlap the ends of the pressure-roll
when the latches are in operative position. During the operation of winding
the warp, the latch bars 50 are thrown back against the rocking bar 4, as shown
in Figure 1; but whenever the pressure-roll is raised in an oblique position,
the latch bar 50 at the lower end of the roll is thrown forward in order to bring
its block 52 over the end of the roll and hold it from sliding endwise in the
arms 20, 21, as represented in Figure 2.
The pressure-roll 23 is variable in length in order to allow for any irregularity
in the spaces between the heads 2, 2 of the warp beam and it is also made in
sections to provide for an approximate adjustment of the pressure-roll to the
length of different warp beams. Figure 8 shows the construction of the pres-
sure-roll which consists of a central section 53, having at one end an extension
piece 54, detachably attached to the central section 53 by a bolt 55 which allows
the extension piece 54 to be exchanged for others of different lengths. At the
opposite end of the pressure-roll is a spring actuated sliding section 56 which is
provided with a concentric recess 57 fitting upon and capable of sliding over
the reduced end 58 of the central section 53 of the roll. The sliding section 56
is acted upon by a spring, or springs, inserted between the ends of the sliding
section and a shoulder 59 of the central section 53.
I prefer to employ two springs 60, 61 separated by an annular collar 62 and
to the outer surface of the collar I attach a thin sheet metal sleeve 63 with its
ends overlapping the central section 53 and also the sliding section 56, so as to
cover the chamber containing the springs 60, 61 and form a continuous surface
on the periphery of the pressure-roll. The sliding section 56 is held upon the
central section 53, and against the action of the springs 60, 61, by means of an
adjusting bolt 64 screwed into the reduced end 58 and provided with a projecting
flange 65 which bears against the recessed end of the sliding section 56.
The sliding movement of the section 56 is limited in one direction by the
flange 65 of the bolt 64 and in the opposite direction by means of an annular
plate 66 which is attached to the recessed end of the sliding section 56 with a
small space between the annular plate 66 and the flange 65 of the adjusting
bolt, a fraction of an inch being usually sufficient, in order to allow for the
variation between the heads 2,2 of the warp beam, due to the heads not being
in parallel planes at right angles to the axis of the warp beam. The adjusting
bolt 64 is provided with a squared end 67 projecting through the annular
plate 66 to receive a wrench and allow the length of the pressure roll to be
varied by screwing or unscrewing the adjusting bolt 64.
The operation of my improved beaming machine is as follows:-The warp
beam is placed in position in its supporting stands 3, 3 and a few turns of yarn
wound thereon. The rocking bar 4 and pressure-roll 23 are then rocked from
their elevated position, as shown in Figure 2, to the position shown in Figure 1,
with the pressure-roll 23 bearing upon the yarn wound upon the barrel 1 of
the warp beam; the axis of the rocking bar 4 having been previously adjusted
by means of the screw threaded spindles 7, 7 and the hooked arms 20, 21 brought
between the heads of the warp beam by means of the pins 48 and holes 49. The
sliding block 29 is then moved along the transverse bar 26 to the rear of the
rocking bar 4 so that the pulling strain exerted by the weight 39 will be exerted
to rock the bar 4 and carry the pressure-roll 23 down upon the warp as it is
being wound upon the warp beam. As the sliding block 29 moves to the rear
of the rocking bar 4 its lower end is brought into contact with the cam surface 47
of the lever 45 causing the pulley block 42 to be drawn down, thereby slackening
the short connecting chain 46 and increasing the pulling strain upon the sliding
block by causing the force of the weight 39 to be exerted through all the
sections a, b, c and d of the chain 40. When the operation of winding is com-
pleted, the sliding block 29 is moved forward of the rocking bar 4 or upon the
same side as the pressure-roll 23; one of the sleeves 5 is detached from the
supporting stand by withdrawing its bolt 6 and the rocking bar and pressure-

page_text: roll are again raised in the oblique position, as represented in Figure 2; or, if
desired, the bar 4 may be rocked in the sleeves 5 without detaching them from
the supporting stands, thereby raising the pressure-roll 23 from the heads 2,2
of the warp beam.
one end
In Figures 9 to 16, I have shown a modified form of constructing the expan-
sible pressure-roll by which the cost is lessened and the weight of
the roll very much reduced. The body of the roll is made from
a piece of piping 68 cut to the proper length and fitted at
with a head 69 recessed concentrically to receive the reduced end 70 of an exten-
sion piece, consisting of a short piece of piping 71 having at one end the cast
iron head 72 and at the other end the flanged pipe 70 of smaller diameter, the
whole being attached to the body of the roll by a bolt 74 screwed into the
head 69. The opposite end of the roll is fitted with a head 75 which extends
some distance into the piping 68 and is provided with a screw thread 76 and a
concentric recess 77 to receive the elongated hub 78 of a sliding head 79.
Held on the elongated hub 78 and between the head 79 and the head 75 are a
series of rings, or annular collars, 80, 81, 82, 83, of different widths, and on the
reduced end 70 of the extension piece are a pair of collars 84 and 85 having
toothed flanges 86, 86, arranged to interlock and inclosed within the toothed
flanges is a spiral spring 87. The elongated hub 78 of the sliding head 79 is
hollow to receive a bolt 88 which is screwed into the screw thread 76, with the
head of the bolt contained in a recess 89 of the sliding head 79.
The bolt 74 is screwed up far enough to cause the toothed flanges 86 of the
collars 84 and 85 to just engage and slightly compress the spiral spring 87 and
the teeth of the flanges 86 are adapted to permit a slight contraction in the
length of the roll. The extension end of the roll can be readily detached by
removing the bolt 74 and others substituted of different lengths and the annular
collars 81 and 83 can also be wholly or in part omitted. The sliding movement
permitted by the interlocking flanges 86 is sufficient to allow for any inequality
in the space between the heads of the warp beam.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
First. The combination of a stand having bearings for supporting the warp
beam, stands having bearings for supporting a rocking frame, a pressure-roll
carried by said rocking frame, and means for vertically adjusting the bearings
of said rocking frame relatively to the bearings of the warp beam, as and for
the purpose set forth.
Second. The combination of a pair of stands for supporting a warp beam, and a
pair of stands for supporting the framework of a pressure-roll, floor plates pro-
vided with oppositely tapered lugs and tapered feet on said stands fitting said
lugs, as and for the purpose set forth.
Third. The combination with the supporting stands of a beaming machine
arranged in pairs, of floor plates on which the stands are supported, having
oppositely tapered lugs, tapered feet on said stands and means for drawing the
stands in each pair together, as and for the purpose set forth.

at one end to a fixed support and passing over said pulleys, a weight suspended
from the opposite end of said cord, a flexible connection between the sections
of the cord on opposite sides of the pulley 38, and means for taking up the cord
and slackening said flexible connection, in order to multiply the force exerted
by said weights, as and for the purpose set forth.
Fifth. The combination of a rocking frame and a pressure-roll carried thereby,
a weight applied to rock the frame, and a flexible connection between the

page_text: weight and the rocking frame by which the weight is suspended, and mechanism
whereby the force exerted by said weight is increased or diminished, as and for
the purpose set forth.

means for raising said roll into an oblique position, and latches for holding the
roll from sliding endwise in the frame, as and for the purpose set forth.
