I, DAVID MCTAGGART, of 91, Exchange Street, Worcester, in the County of
Worcester and Commonwealth of Massachusetts, United States of America,
Manufacturer, do hereby declare the nature of my invention for improvements
in warp beaming machines to be as follows:-
My improvements relate to machines for simultaneously winding a number
of individual strands side by side upon a single spool, or beam, adapted to be
used in a
weaving loom and constituting the warp beam and particularly to
that class of warp beaming machines in which pressure is applied to the warp
as it is being wound upon the warp beam by means of a compressing roll bearing
against the warp after it has been wound upon the beam and having means for
applying pressure to the compressing roll, whereby the warp is compressed between
the compressing roll and the barrel of the warp beam.
A warp beaming machine having compressing mechanism of the class referred
to, comprises a rocking shaft having radially projecting arms provided with
claws at their free ends, which enclose a little more than half of the periphery
of a metallic compressing roll with its axis parallel with the axis of the warp
beam and of suitable length to go between the heads of the warp beam and
rest upon the warp after it is wound. It also comprises a suspended weight
operatively connected with the rocking shaft so as to carry the compressing roll
against the warp upon the warp beam and apply the desired pressure thereto.
I. The first part of my invention relates to the arrangement, in the organized
machine, of the warp beam and the rocking shaft which carries the compressing
roll and its actuating mechanism, whereby the upper and front sides of the
warp beam are left entirely free for the attendant; the rocking shaft and its
actuating mechanism being located below and to the rear of the axis of the
warp beam, and it consists in placing the rocking shaft at the rear side of and
below the plane of the axis of the warp beam and carrying the compressing roll
in claw arms which extend vertically upward from the rocking shaft at the
rear side of the warp beam and in operatively connecting the rocking shaft, by
means of segmental gears, with a second rocking shaft which extends beyond
the end of the warp beam; said second rocking shaft having at one end a radial
arm connected with a suspended weight which exerts a pulling strain to rock
the connected shafts and carry the compressing roll against the warp upon the
warp beam.
II. The second part of my invention relates to the actuating mechanism by
which the warp beam is rotated, whereby the speed of the warp beam can be
reduced as the warp beam increases in size, in order to render the circum-
ferential speed of the warp as it moves against the compressing roll approxi-
mately the same, and it consists in driving the warp beam by means of a belt
connection between cone pulleys and in interposing so-called "back-gears" be-
tween the cone pulley and the warp beam with a double clutching mechanism by
which the cone pulley can be connected with the warp beam either with, or
without, the intervention of the "back-gears."

page_text: III. The third part of my invention relates to mechanism by which the pulling
strain exerted by the suspended weight can be counteracted by the operator for
the purpose of removing the compressing roll from the surface of the warp,
and it consists in providing the rocking shaft, to which the suspended weight
is directly connected, with a segmental ratchet and pivoting a lever handle
to said ratchet by a pin passing through a slot in the handle; said handle having
a pin projecting from its side adapted to be carried into and out of engagement
with one of the teeth of the ratchet by the radially sliding movement of the
lever on its pivotal pin. By raising the lever handle and carrying it into engage-
ment with one of the teeth of the segmental ratchet and then depressing the
lever, the rocking shafts are reversed, thereby raising the suspended weight and
carrying the compressing roll out of contact with the warp upon the beam. A
hook is provided upon the end of the framework arranged to engage the lever
handle and hold it in its depressed position, thereby maintaining the compressing
roll out of contact with the warp.
1V. The tourth part of my invention relates to the device for adjusting the
axis of the rocking shaft which carries the compressing. roll, in order to bring
the axis of the compressing roll parallel with the axis of the warp beam, and
it consists in journalling the ends of the rocking shaft which carry the com-
pressing roll in bearings, which are attached to and horizontally adjustable on
the upper ends of the screw threaded spindles, or stems, capable of being raised
or lowered in the framework, in order to elevate or depress the ends of the rocking
shaft. I thereby make the journal bearings of the rocking shaft, which carries
the compressing roll, adjustable in both horizontal and vertical planes, thereby
enabling the axis of the compressing roll to be brought parallel with the axis
of the warp beam.
V. My fifth improvement relates to friction rolls journalled in claw arms with
their peripheries in contact with the compressing roll, and it consists in making
each of the friction rolls of three concentric disks of the same diameter and each
capable of independent rotation; the purpose of this improvement being to
obviate the jumping or irregular rotation of the compressing roll due to the wearing
When each roll consists
away or flattening of the peripheries of the friction rolls.
of three disks of the same diameter running side by side and capable of inde-
pendent rotation, the flattening of the surface of one disk does not affect the
rotation of the compressing roll, as it is supported by the surfaces of the other
two disks and a flattened spot in the peripheries of each of the three disks
would not affect the rotation of the compressing roll, unless the three flattened
spaces happened to coincide as the disks rotated.

I, DAVID MCTAGGART, of 91, Exchange Street, Worcester, in the County of
Worcester and Commonwealth 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:-
My improvements relate to machines for simultaneously winding a number
of individual strands side by side upon a single spool, or beam, adapted to be
used in a weaving loom and constituting the warp beam and particularly to

page_text: that class of warp beaming machines in which pressure is applied to the warp
as it is being wound upon the warp beam by means of a compressing roll bearing
against the warp after it has been wound upon the beam and having means for
applying pressure to the compressing roll, whereby the warp is compressed between
the compressing roll and the barrel of the warp beam.
A warp beaming machine having compressing mechanism of the class referred
to, comprises a rocking shaft having radially projecting arms provided with
claws at their free ends, which inclose a little more than half of the periphery
of a metallic compressing roll with its axis parallel with the axis of the warp
beam and of suitable length to go between the heads of the warp beam and
rest upon the warp after it is wound. It also comprises a suspended weight
operatively connected with the rocking shaft so as to carry the compressing roll
against the warp upon the warp beam and apply the desired pressure thereto.
In the following description of my invention and the manner in which the
same is to be performed, reference is made to the reference letters and figures
in the accompanying drawings which represent a portion of a twisting machine,
having a winding mechanism embodying my invention, showing the manner
of putting my invention into practice and forming a part of this specification.

Figure 9 is a central, sectional view of the friction rolls in contact with the

Like parts are indicated in the accompanying drawings by like letters and
figures of reference.
Referring to the accompanying drawings, 1 denotes the bed, or that portion
of the framework upon which the warp beam is mounted, and upon which are
the supporting brackets 2 and 3 provided with journal bearings for a hollow
shaft 4 and a bracket 5 which is adjustable along the bed 1 to accommodate
warp beams of different lengths.
The warp beam comprises the heads 6 and 7 connected by a barrel 8 upon
which the warp 9 is wound and having a gudgeon 11 journalled in the bracket 5
and a gudgeon 10 inserted in the hollow shaft 4. The head 6 of the warp beam
is connected by a dog 12 with one of the arms of a gear wheel 13 which is attached
to the hollow shaft 4 and engaged by a pinion 14 on one end of the shaft 15
journalled in bearings within the bed 1 and carrying at its opposite end a gear 16
which is engaged by a pinion 17 on a countershaft 18 journalled in brackets 19, 19,
which project from the side of the bed 1.
Turning loosely upon the countershaft 18 is a cone pulley 20 provided with
steps 21, 22. The cone pulley 20 is provided with a hub carrying a pinion 23
and having clutch teeth 24 engaging similar clutch teeth on the hub 25 of a
gear 26 which has a spline connection with the counter shaft 18 and is capable,
of a sliding movement on the shaft by means of a hand lever 27 engagaing a
neck on the hub 25 and pivoted at its lower end upon a bracket 28 projecting
from the side of the bed 1.
One of the brackets 19, at the end of the countershaft 18, serves to limit the
'

page_text: sliding movement of the gear 26 on the shaft 18 as the clutch teeth are dis-
engaged. Journalled within the bracket 28 is a shaft 30 carrying upon one end
a gear 31 and on the opposite end a pinion 32. The gear 31 engages the pinion 23
and the pinion 32 engages the gear 26 when it is brought against the fixed
brackets 19.
The cone pulley 20 is driven by a belt connection from a similar cone pulley
on an overhead shaft; the step 21 and 22 allowing two different speeds to be
given to the cone pulley 20.
By bringing the clutch teeth on the hub 25 into engagement with the clutch
teeth 24, the rotation of the cone pulley 20 is communicated directly to the shaft 18
and through the intermediate shaft 15 to the gear 11 and connected warp beam;
but when the gear 26 is moved against the bearing 19, the clutch is separated
and the gear 26 is brought into engagement with the pinion 23, causing the
rotation of the cone pulley to be imparted to the countershaft 18 through the
intermediate shaft 15 and with a reduced speed.
I am therefore able to rotate the warp beam at four different speeds; two speeds
being obtained by means of the steps 21 and 22 with a direct connection between
the cone pulley 20 and the shaft 18, and two speeds by means of the steps 21
and 22 with the cone pulley connected with the shaft 18 through the intermediate
shaft 30, and the speed of the warp beam can be decreased at different periods
in the process of winding, in order to maintain approximately the same circum-
ferential speed of une winding surface as the beam increases in size.
Arms 33, 33, attached to one side of the bed 1, extend upwardly and carry
in their upper ends a roll 34 over which the warp threads are conducted to the
rotating bcam between the barrel & and the compressing roll 35 which rotates
in contact with the warp 9 as it is wound upon the beam and is held in the
arms 36, which inclose a little more than half of the periphery of the compressor
roll and are attached to a rocking shaft 37 carrying a segmental gear 38, which
is engaged by a similar segmental gear 39 on a rocking shaft 40. The rock-
ing shaft 40 is provided with an arm 41 extending horizontally to-
ward the bed with its end 42 turned vertically upward, and
also with an arm 43, which extends vertically upward and is con-
nected at its upper end with the upturned end 42 of the arm 41 by a bar 44
forming a way, or track, for the sliding block 45 to which a nut 46 is attached
engaging the threads of a screw 47 journalled in the arm 43 and the upturned
end of the arm 41 and provided with a crank arm 48, by which the screw may be
rotated for the purpose of sliding the block 45 along the track 44. The block 45
carries the scored pulleys 49 and 50, connected by a cord, or chain, 51 with the
scored pulleys 52 and 53 carried in blocks 58 and 59 suspended from a cross
bar 60, which is supported upon upright posts 61, 61, held at their lower ends
ends by the framework of the machine.
One end of the cord, or chain, 51 is attached to a pulley block 58 and, after
passing around the pulleys 49, 50, and 52, 53, it is connected at its opposite end
with a weight 62, causing a pulling strain to be exerted on the arm 41, thereby
tending to rock the shaft 40 and also by means of the segmental gears 39 and 38,
to rock the shaft 37 and carry the roll 35 against the warp 9, as it is being wound
upon the warp beam. The pressure exerted by the roll 35 upon the warp can
be varied by either increasing or diminishing the weights 62 and also by moving
the block 45 along the track 44, thereby varying the radial distance at which
the pulling strain of the weight. 62 is applied to the arm 41. The rocking shafts 37
and 40 are supported upon brackets 63, bolted at one end to the under side of
the bed 1 and provided with feet 64 which rest upon the floor.
The rocking shaft 37 is journalled in sleeves 65, 65, which are held in plates 66
having an opening 67 on their upper side equal to the diameter of the rocking
shaft 37, so that by sliding the sleeves 65 lengthwise on the shaft 37 and with-
drawing them from the plates 66 the shaft 37 may be removed through the
openings 67. When the sleeves 65 are in position in the plates 66, they are held

page_text: from longitudinal movement by their flanges 68, which are interposed between
the plates 66 and cotter pins 69 inserted in the shaft 37.
The plates 66 are attached to the flanged steps 70 and are horizontally adjust-
able thereon, by means of screws 71 which pass through slots 72 in the flanges 73
of the step 70 and enter the plates 66. The steps 70 are provided with screw
threaded stems 74, which enter screw threaded holes in the bracket 63, which
allows each end of the rocking shaft 37 to be raised, or lowered, in order to bring
the axis of the compressing roll 35 into the same plane as the axis of the warp
beam, while the horizontal adjustment of the plates 66 on the steps 70 allows
the axis of the compressing roll 35 to be brought parallel with the axis of the
warp beam.
The rocking shafts 37 and 40 are supported upon the brackets 63, which are
bolted to the bed 1 and the upright posts 61, which support the upper pulley
blocks 58 and 59, are attached at their lower ends to the framework of the machine,
and the entire operating mechanism is therefore contained in a single framework,
so that when the operating parts are once adjusted relatively to each other,
the entire mechanism may be moved into any desired position.
Connected to one end of the rocking shaft 40 and preferably attached to one
side the arm 41, is a hollow segmental ratchet 75 having ratchet teeth 76 on
its circular side. The hollow ratchet 75 is open on its toothed side for the inser-
tion of a lever handle 77, which is provided with a short slot 78 in the end
inserted in the ratchet, and passing through the slot 78 is a pin 79 held in the
ratchet 76, thereby allowing a slight endwise movement of the lever handle 77
on its pivotal pin 79. The lever 77 carries a pin 80 projecting upon the opposite
sides of the handle and adapted to engage the ratchet teeth 76 when the lever
handle 77 is pushed into the ratchet and to be disengaged from the ratchet teeth
by the opposite movement of the lever handle on the pin 79.
By raising the lever 77 and sliding it on the pin 79, the pin 80 can be carried
into engagement with the teeth 76 to give the proper elevation to the free end
of the lever handle. The depression of the lever 77 will then rock the shaft 40,
thereby raising the weight 62 and rocking the shaft 37 to carry the roll 35
out of contact with the warp on the warp beam, in order to allow access to the
warp threads between the warp beam and the roll 35 for the purpose of mending
broken ends, or allowing the removal of the warp beam when filled, and the
roll can be permanently held away from the warp by carrying the lever 77 under
a hook 80 attached to the end of the bed 1.
The roll 35 rotates in contact with small friction balls carried in the arms 36
and indicated by the broken lines 81 and is of the proper length to extend between
the heads 6 and 7 of the warp beam. The friction rolls 81 at each bearing point
of the roll 35 comprises two or more rolls of the same diameter rotating about
a common axis, as shown in central sectional view in Figure 9, where the set of
rolls forming one of the bearings of the roll 35, consists of the three rolls a, b
and c, of the same diameter. The central roll a is provided with hubs on each
side, on which the side rolls b and c turn. When a single roll is employed, it
is liable to become worn in spots on its periphery, causing an irregular motion
of the compressing rolls as it comes in contact with the worn spots, and this
difficulty is overcome by using a multiplicity of rolls, with each capable of
independent rotation. In case one of the rolls becomes worn out of round, the
compressing roll will be supported on the peripheries of the remaining rolls as
it passes over the worn spot, and should portions of each roll become worn out
of round, the worn spots of each must coincide to affect the movement of the
compressing roll. The entire mechanism for rotating the warp beam and applying
pressure to the warp compressing roll, is located upon the back side of the warp
beam, leaving the front and upper side of the warp beam entirely free for the
attendant and providing a free space for the removal of the warp beam.
The shaft 18 carries a ratchet 82, which is engaged by a pawl 83 pivoted upon
the fixed framework of the machine, in order to check the reverse motion of the

page_text: warp beam. A spring 84 incloses the shaft 18 with one of its ends 85 engaging
the pawl 83, so that when the shaft 18 turns in one direction, the end 85 of the
spring will be thrown down by the frictional contact between the spring 84
and the shaft 18, thereby rocking the pawl 83 and carrying it into engagement
with the teeth of the ratchet, while the movement of the shaft 18 in the opposite
direction will raise the pawl 83 out of engagement with the ratchet, so the end
of the pawl will not ride on the ratchet teeth while the warp is being wound.
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. warp compressing mechanism comprising a pair of rocking shafts
