Improvements in Swivel Looms.
I, EDWARD HOLLINGWORTH, of Dobcross Loom Works, Dobcross, in the County of
York, Power Loom Maker, do hereby declare the nature of this invention (which
has been communicated to me by George Frank Hutchins, of The Knowles. Loom
Works, Worcester, in the State of Massachusetts, in the United States of America,
Power Loom Maker) and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention relates to swivel looms, or looms provided with swivel shuttle
attachments, the swivel shuttles being used in addition to the ordinary fly shuttle,
to make spots or figures on the fabric.
The object of my invention is to improve upon the construction of swivel looms
as now ordinarily made, and more particularly to make a swivel loom entirely
automatic in its operation in which the whole of the warp threads, or any portion
of them, may be covered by the movement of the swivel shuttles, so that a figure
may be woven covering the entire width of the fabric, or only a few threads thereof,
as desired. The movement of the swivel shuttles is entirely automatic, and the time
of movement is indicated by the jacquard, so that they may be automatically called
at will, both as regards their downward movement into the shed, and their side
movement across the warp. The fabric may be woven with the embroidery figure
on both sides, or on one side only, or partly on one side, and partly on both sides,
as described.
My invention consists in certain novel features of construction of a power swivel
loom of the description above referred to, as will be hereinafter fully described.
I have shewn in the drawings only sufficient portions of a power loom, having my
improvements applied thereto, to enable those skilled in the art to understand the
construction and operation thereof.
Referring to the drawings

In the accompanying drawings, 1 are the loom sides or frames, 2 the arch stands,
3 the front arch, 31 the back arch, 4 the breast beam, 5 the lay, 6 the lay swords
pivotally mounted at their lower ends on the shaft 7, and having the upwardly
extending lay sword horns 61, to which is bolted the hand rail, 8, 8' is the reed,
9 are the crank connectors, which connect the lay 5 with the crank shaft 10, 11 is
the bottom or driver shaft, which is geared to the crank shaft 10 through gears 12
and 13, as shewn by broken lines Figs. 2, 3 and 4. 14 is the picking shaft, which
extends at right angles to the bottom shaft 11, and carries the picking shoe 15,
which is operated upon by the rolls 16 carried by the arms or castings 17 on the
bottom shaft 11. All of the above parts may be of the ordinary construction.
The sliding pick mechanism for controlling the action of the fly shuttle operating
mechanism may be of any well known construction.
Said sliding pick mechanism consists of two sliding rods 18 and 19 supported
and sliding at their inner ends in a stand 20 secured to the lower cross girt 21, and
at their outer ends in the loom sides. The inner ends of the rods 18 and 19 are
connected by curved arms 22 to a lever 23 centrally pivotted on the stand 20, so
that said rods are caused to move simultaneously in opposite directions. Each
rod 18 and 19 has a forked arm or yoke 24 secured thereto, which engages with the
grooved hub 17¹ of the arm or casting 17 carrying the rolls 16. The castings or
arms 17 are mounted on the bottom shaft 11 to slide thereon, and to revolve
therewith, and to be moved into or out of engagement with the picking shoes 15,
according to the movement of the sliding rods 18 and 19, see Fig. 1.
The movement of the sliding rods 18 and 19 is controlled from the jacquard, not
shewn, through intervening mechanism, which is shewn more particularly in
Figs. 2, 2, 14 and 15.

page_text: Referring to said figures; 25 is a longitudinal sliding arm or lever supported and
sliding at its outer end in a box or stand 26 bolted to the loom side, and supported at
its inner end on the bottom shaft 11, which extends through a slot 251 in said lever 25,
which is on the outside of the loom side. A spring 26¹ acts on the end of the
lever 25, to hold it in position.
The bottom shaft 11 has a cam 27 fast thereon, which as the shaft revolves, is
brought into engagement with a finger 28 pivotted on the inner end of the arm 25
in the path of said cam 27, or with the finger 29 pivotted upon the arm 25 on the
opposite side of the shaft, and in the path of the cam 27, to move the arm 25 in one
direction or the other, according as the indicator lever 30, pivotted at one end on
the arm 25 is raised or lowered by the cord 31, as shewn in Fig. 2 and Fig. 2ª.
A pin or stud 32 on the outer end of the sliding rod 19 extends into a diagonal
slot 25 in the arm 25, see Figs. 14 and 15, so that the longitudinal motion of the
arm 25, according as the finger 28 or finger 29 is moved into the path of the cam 27,
communicates a sliding motion to the sliding rod 19, and also to the sliding rod 18,
to move the picking rolls 16 out of engagement with the picking shoe 15, to stop
the action of the fly shuttle mechanism, or into engagement with the picking shoe
to operate the fly shuttle mechanism, according to the indications of the jacquard.
The cord 31 is connected through a spring 33 with the angle lever 34 pivotted on
a stand 35 secured to the back arch 31, see Figs. 1 and 2. A cord 36 connects the
upper arm of the lever 34 with the lever 37, pivotally supported at its lower end on
a stud 38 in an arm or bracket 39 secured to the rear arch 31, see Fig. 4. The
arm 39 has a stnd 40 extending out therefrom, on which is loosely mounted a
cam 41 having the two outwardly and downwardly extending arms 41'. The stud 40
extends through a horizontal slot 371 in the arm 37, and at each end of said slot, on
the arm 37 are studs or pius 42, which extend out therefrom and are adapted to be
engaged by the cam 41, to move the lever 37 in one direction or the other, and
through cord 36, lever 34, and cord 31, raise or lower the indicator lever 30.
The cam 41 is so shaped and pivotally supported with reference to the studs 40
on the lever 39, that when it is moved to one extreme position or the other on its
"pivotal support, as shewn in Figs. 12 and 13, it is locked in this position until the
connection to the jacquard moves it in the opposite direction, thus preventing the
accidental movement of said cam.
In addition to this locking construction of the cam 41, I may employ the
additional locking device shewn in Figs. 12 and 13, which consists of a lever 43
centrally pivotted on the upper central part of the cam 41, and having curved arms
connected at their outer ends by springs 44 to the lever 37, so that the cam 41
moving in either direction beyond its centre, as shown in Figs. 12 and 13, is held
or locked in this position by means of the springs 41 in connection with the
arins 43.
The cam 41 is rocked on its pivotal support in one direction or the other,
to move the lever 37 by cords 45 leading to the jacquard, not shewn.
I will now proceed to describe the swivel shuttle mechanism, and the operating
mechanism therefor shewn in the drawings.
At each end of the lay is secured an upright slotted stand 46, see Fig. 3, in which
is mounted or held to have an up or down motion in front of the reed and over the
race plate 47 on the lay, a transverse bar 48, carrying the downwardly extending
fingers 49 secured at their upper ends, in this instance by screws 50 upon the front
of said bar, as shewn in Figs. 7 and 8, and having their lower ends 491 preferably
curved inwardly as shewn in Figs. 6 and 10.
The fingers 49 have transverse grooves 51 with undercut edges in their front
surfaces at the lower part thereof, into which extend and are supported the inner
ends of the swivel shuttles 52, which extend out from the fingers 49 in a horizontal
plane, and are preferably made of the shape shewn in Figs. 6 and 10, being open
on their upper side to receive the spool 53 on which the thread is wound, and
through which a central spring spindle 531 extends, to form a support for said spool
to turn on; a tension device 53 comprising the central spindle 53¹ and two spiral
springs & surrounding the said spindle, as shewn in Fig. 10, being used to keep the

page_text: proper tension on the thread, so that as the thread is pulled off in the process of
weaving, the spool does not over run and leave the thread slack as would be the
case without the two springs 8.
I may use a swivel shuttle of the description shewn in Fig. 11, in which the
spool 53 is supported independently of the shuttle 52 in a removeable holder 52¹,
preferably made of metal, and of the shape shewn. The holder 52¹ extends in two
vertical grooves or recesses in the shuttle body, and is held therein. The advantage
of the holder 52 for the spool 53 is that the spring spindle 531 can be properly
adjusted when the spool is placed in the holder 52¹, and does not require any
further adjustment when the holder is placed in the shuttle 52.
The bolder 52¹ has an opening 52" through its upper surface, through which the
thread is passed from the spool 53, see Fig. 11.
The swivel shuttles 52 are adapted to be moved back and forth from one
finger 49 to the adjoining finger, to carry the shuttle under and over the warp
threads which extend in the space between two of the fingers 49 and are called
by the jacquard. The pointed ends 49¹ of the fingers 49 are arranged to extend
in the front of a dent in the reed, and in descending into the shed divides the
warp threads and pushes the different sets of warp threads into the spaces between
the fingers, so that the whole width of the fabric, or any desired width thereof,
may have a figure or figures woven thereon by the swivel shuttles, at any point
desired. Where the figures are not to be woven, the jacquard does not call
the warp threads for the swivel shuttles, and they therefore act as dead
shuttles.
The swivel shuttles 52 are moved transversely from one finger to the adjoining
finger and back, in this instance by means of levers 54, which are operated
automatically in the manner to be hereinafter described, and which are pivotted on
the fingers 59 by pins or studs 54, and are adapted to engage with their lower pointed
ends the necks of the swivel shuttles, to move them in one direction or the other,
according to the movement of the levers 54.
There is a lever 54 for each swivel shuttle 52, the upper end of each lever 54
extending loosely through a hole or opening in the head of the pins or studs 55
mounted to oscillate or turn in the sliding bar 56; said heads extend out from the
front side of said bar, and a transverse pin 55¹, serves to retain the studs in
the bar.
The sliding bar 56 is mounted to slide longitudinally on the upper grooved edge
of the bar 48, see Fig. 6, and motion is communicated to slide said bar 56 in one
direction or the other, to move the levers 54, and through said levers move the swivel
shuttles 52 from one finger to the adjoining finger, by mechanism to be hereinafter
described.
Each swivel shuttle 52 is held in the transverse groove 51 in the finger 49, to
prevent its accidentally sliding out of position, in this instance by a ball 57 held in
an opening in the finger 49, and pressed into a depression in the inuer end of the
neck of the shuttle, by a spring 58 secured by a screw 59 to the finger 49, as shewn
in Fig. 10.
Instead of using the swivel shuttle 52 of the shape and construction shewn in
Figs. 6 and 10, I may use a swivel shuttle 60 of the shape and construction shewn
in Fig. 9, and instead of using a ball 57 to hold the shuttle in position, I may use a
spring actuated plunger 61 shewn in said Fig. 9, or any other suitable device.
I will now describe the mechanism for automatically lowering and raising the
swivel shuttle mechanism, that is the bar 48 and the sliding bar 56, and the parts
supported thereon, so that the swivel shuttles will be lowered into the shed, as
shewn in Fig. 6, and raised out of the shed, in the operation of weaving the figures
on the underside of, or on both sides of the fabric, woven in the loom by the
ordinary fly shuttle mechanism, not shewn.
To each end of the bar 48 carrying the fingers 49 supporting the swivel shuttles 52,
is secured the upper end of an upright rod 62. Each rod 62 has a vertical motion,
and one of said rods 62 is pivotally attached to the front end of a lever 63, see

page_text: 5
Fig. 4, secured at its inner end on a rock shaft 64 mounted in hangers 65 secured
to the loom sides.
The lower end of the other rod 62 is pivotally secured to the front end of the
lever 66 centrally secured ou the rock shaft 64, see Fig. 3. The other end of
the lever 66 carries a roll mounted on a stud 67 in said lever, and a cam 68 fast on
the bottom shaft 11 engages said roll to communicate motion to the lever 66, and
through rock shaft 64 to the lever 63, to raise the rods 62 at the proper time, and
with them the swivel shuttle bar.
As the cam 68 revolves, the weight of the swivel shuttle bar causes it to be
lowered, to carry the swivel shuttles, into the shed and keeps the roll on the lever 66 in
engagement with the cam 68. A spring or other means may be used to keep the
roll in engagement with the cam if preferred.
The rear end 66¹ of the lever 66 extends beyond the roll on said lever engaged
by the cam 68 toward the back of the loom, see Fig. 3, and is adapted to be engaged
when the swivel shuttle mechanism is raised out of the shed and the fly shuttle
mechanism is in operation, to avoid any possibility of the swivel shuttles and fly
shuttle coming in contact with each other, by one arm 691 of an angle lever 69,
which is pivoted on a stud 70 fast in the upper end of a stand 71 secured to the
loom side, see Figs. 1 and 3. The opposite arm of the angle lever 69 is provided
with a stud or pin 72, which extends into a slot 73¹ in the arm 73 fast on the sliding
rod 19, see Fig. 1. It will thus be seen that when the sliding rod 19 is moved to
the left, to bring the picking rolls 16 into position to engage the picking shoes, as
shown by dotted lines in said figure, then through the arin 73 the angle lever 69 will
be rocked to move down the arm 691 thereof, and cause it to extend over the end 66¹
of the lever 66, preventing said lever from moving, as long as the fly shuttle
mechanism is in operation.
When the picking rolls 16 are moved in the opposite direction to throw out of
action the fly shuttle mechanism, the angle lever 69 through arm 73 will be
moved, and the arm 69¹ thereof raised, as shewn in Fig. 1, to allow the lever 69 to
move, and the swivel shuttles to be lowered into the shed.
I will now describe the mechanism for communicating a longitudinal motion to
the sliding bar 56, and through levers 54, to move the swivel shuttles 52 from one
finger to an adjoining finger, after they are lowered into the shed, or raised out of
the shed.
To each end of the sliding bar 56 is connected the upper end of an angle lever 74,
which is pivotted in this instance in the lower end of an arm 75 secured to the
bar 48 carrying the fingers 49. The other arm of the angle lever 74 is connected
by a cord 76, which passes over a pulley 77 mounted in an arm 78 secured on the
upright rod 62, see Fig. 5. The inner ends of the cords 76 are secured to the front
ends of a lever 79, which is pivotally supported at its central portion to swing in a
horizontal plane on a stud 80 secured in the lower end of a hanger 81 secured to a
cross girt 82 on the loom frame, see Figs. 3 and 4.
The inner end 791 of the lever 79 is provided with a stud 83, on which is
mounted a roll 84, see Figs. 1 and 4, which extends into and travels in a cam
groove 851 cut in the periphery of a drum 85. Said pulley 85 is fast on a stud or
shaft 86 mounted in an arm extending up from a girt 88 which extends between
the rear cross rod 87 and the front rod 89, see Figs. 3 and 4.
Fast on the hub of the drum 85 is a star wheel 90, which is operated by a pin
wheel 91 keyed on a sleeve 92 secured to the bottom shaft 11 by a bolt 93
extending in a collar or head 94 on one end of the sleeve 92, see Fig. 1.
The pin wheel 91 is caused to slide on the bottom shaft 11, to move into and out of
engagement with the star wheel 90 by a two armed lever or yoke 95 provided
with pins or studs 95' extending into an aunular groove 96 in a pulley 90
forming a part of the pin wheel 91.
The lever 95 is pivotally supported on a stud 97 secured in a side extension 881
on the girt 88, see Figs. 1 and 4, and has an arm 95 extending out therefrom, to

page_text: the outer end of which is attached one end of a spiral spring 98, the other end of
the spring 98 is in this instance secured to the floor.
To the arm 95" is also attached the lower end of a cord 99, which leads over a
pulley 100 supported in this instance on the back arch 31. The other end of the
cord 99 is attached to the rocking lever 37, see Fig. 1, said lever, the cam 41, and
the other parts connected therewith being of substantially the same construction
and operation as the lever 37 and the parts connected therewith shewn at the left
in Fig. 1, which have been already described, and similar letters are used to repre-
sent similar parts. The additional locking mechanism shewn at the left in Fig. 1
is not shewn in connection with the oscillating lever mechanism shown at the right
in Fig. 1, and also shown in Fig. 16, and only one locking stul or pin 42 is shewn,
the spring 98 acting on cord 99 to hold the cam 41 in its opposite position.
Cords 45 lead to the jacquard mechanism, not shown.
It will thus be seen that the engagement of the pin wheel 91 with the star
wheel 90 to operate the drum 85 through lever 79, and communicate a longitudinal
motion to the sliding bar 56, to move the swivel shuttles, is controlled by the
jacquard. The movement of the left hand jacquard cord 45¹, see Fig. 1, acts to
move the rocking lever 37 to the right, and through cord 99 and lever 95 moves the
pin wheel 91 into engagement with the star wheel 90 as shewn in Fig. 1, and thus
communicates to the drum 85 an intermittent motion, and in this instance one-sixth
of a revolution.
While the movement of the right hand jacquard cord 45¹ will move the rocking
lever 37 in the opposite direction to the left, and allow the spring 98 to act to move
the pin wheel 91 out of engagement with the star wheel 90, and leave the star
wheel 90 and the drum 85 at rest.
The cam groove 85¹ in the drum 85 is of such shape that a one-sixth revolution
of said drum, which is communicated to it at each engagement of the pin wheel 91
with the star wheel 90, will move the levers 54 which operate the swivel shuttles 52,
from the position shewn in full lines Fig. 7 to the position shewn in full lines
Fig. 8, and then to the position shown by dotted lines Fig. 8, so as to move the
lower ends of the levers 54 out of the spaces between the swivel shuttles and fingers,
to allow the shuttles and fingers to go down into the shed, and the warp threads to
pass up between
the same, without engaging with the lower ends of the
levers 54.
Referring to Fig. 18, which shews in plan the cam groove 85' in the drum 85
shewn in Fig. 17. Supposing the drum 85 to be revolving in the direction of
arrow f, the long portion of the cam groove marked X will carry the roll 84, shewn
in said Fig. 18 from the position V to the position W. This will shift the levers 54
through the lever 79, cords 76, angle lever 74, and sliding bar 56, from the position
shewn in Fig. 7 to the position shewn in Fig. 8. The cam portion Y in the
continued revolution of the drum 85 will carry the roll 84 to the position O, and
will move back the levers 54 from the position shewn by full lines Fig. 8, to the
position shewn by dotted lines Fig. 8, and during the intermission of the movement
of the drum, the swivel shuttles may be lowered into the shed for example, and
after they are lowered into the shed, the drum 85 being again put into operation,
the long cam portion Z will carry the roll 84 to the position N, and will move the
levers 54 from the position shewn by dotted lines, Fig. 8 to the position shewn by
full lines Fig. 7. The continued revolution of the drum 85 will cause the short
cam portion M to move the roll 84 to the position V, and the levers 54 from the
position shewn by full lines Fig. 7 to the position shewn by dotted lines same
figure, and then the movement above described, will be repeated.
It is necessary to have the drum 85 provided with a cain groove of such shape
that the levers 54 will be moved to throw the swivel shuttles in one direction, and
then the levers partially moved back, to leave a clear space for the warp
threads to pass up between the swivel shuttles and their supporting fingers, as
above described.

page_text: The connection of the pin wheel or other mechanism for operating the drum 85
with the jacquard, controls the movement of the swivel shuttles from the jacquard,
to weave the spot or figure ou the under side of the fabric.
From the above description in connection with the drawings, the operation of
my improvements in swivel looms will be readily understood by those skilled
in the art.
Supposing the fly shuttle operating mechanism is out of operation, as shown in
Fig. 1, and the swivel shuttles have been lowered into the shed, as shewn in Fig. 6,
and the pin wheel 91 has been moved ready to engage the star wheel 90. Upon
engagement of the pin wheel with the star wheel, a one-sixth revolution is
communicated to the drum 85, and the swivel shuttles 52 are shifted, as above
described, for instance from the position shewn in Fig. 7 to the position shewn in
Fig. 8, to carry the embroidering thread under whatever threads are raised between
the different spaces, between the swivel shuttles, and their supporting fingers. The
disengagement of the pin wheel 91 from the star wheel 90 leaves the star wheel and
drum 85 at rest, and the revolution of the cam 68, fast on the bottom shaft 11, see
Fig. 3, through lever 66 and lever 63, raises the rods 62, and with them the bar 48
carrying the swivel shuttles and their supporting fingers out of the shed.
While the swivel shuttles are being raised out of the shed, the jacquard, through
connections therewith, operates the fly shuttle sliding pick mechanism, so that the fly
shuttle will operate to put in the filling. In case the swivel shuttle mechanism is to
continue to operate, the picking rolls are moved, through the jacquard, to stop the
operation of the fly shuttle mechanism, and the continued revolution of the cam 68
brings the lower part of said cam over the roll on the lever 66, and allows the front
end of said lever 66 and of the lever 63 to be lowered, to carry down the rods 62
and the bar 48, to again bring the swivel shuttles into the shed. Through the
jacquard, the pin wheel 91 is again moved into engagement with the star wheel 90,
and gives to the drum 85 another partial revolution, which shifts the swivel
shuttles from the position shewn in Fig. 8 to the position shewn in Fig. 7, and
they are then raised out of the shed, and the filling put in as above described.
In case there is to be plain weaving between the spots or figures, then, through
connections to the jacquard, the pin wheel 91 will be held out of engagement
with the star wheel 90 for the number of picks of plain weaving which are to be
put it, and at the same time, the jacquard will act to hold the picking rolls in contact
with the picking shoes of the fly shuttle mechanism.
It will be understood that the details of construction of the several parts of my
loom may be varied if desired.
Having now particularly described and ascertained the nature of my said inven-
tion aud in what manner the same is to be performed, I declare that what I
claim is
1. In a swivel shuttle loom, the combination with a series of fingers, and swivel
shuttles supported thereon, and a locking device for retaining the swivel shuttles in
place upon the fingers, and levers pivotted on said fingers, to move said swivel
shuttles, of mechanism for automatically moving said levers in one direction, and
then partially moving them in the opposite direction, to move them out of the space
between the fingers, said mechanism consisting of a cam surface or drum, and
intervening connections to said levers, substantially as shown and described.
2. In a swivel shuttle loom, the combination with a series of fingers, and swivel
shuttles supported thereon, and levers pivotted on said fingers to move said swivel
shuttles, of mechanism for automatically moving said levers to move the shuttles from
one finger to an adjoining finger, and a locking device for retaining the swivel
shuttles in place upon the fingers, comprising a spring actuated ball supported in an
opening in said finger, and extending into a recess in the inner end of the swivel
shuttle, substantially as shewn and described.
3. The combination with a series of fingers, and swivel shuttles supported thereon,
and levers pivotted on said fingers to move said swivel shuttles, of mechanism for

page_text: automatically moving said levers in one direction, and then partially moving them
in the opposite direction to move them out of the space between the fingers, said
mechanism consisting of a cam surface or drum and intervening connections to said
levers, substantially as shewn and described.
4. In the mechanism connected with the jacquard cords, the combination with an
arm having a stud thereon, a cam supported on said stud to have an oscillating
motion, and having two oppositely extending arms to which the cords leading to the
jacquard are attached, a lever centrally pivotted on said can, and having oppositely
extending arms connected by springs to a lever pivotally supported on said arm, and
having a slot therein through which the stud on said arm extends, and said pivotally
supported lever, and a stud or pin on said lever to be engaged by said cam to move
said lever according to the indications of the jacquard, said cam being locked at the
extreme position of its movements, substantially as shown and described.
