I. EDWARD HOLLINGWORTH, of Dobcross, in the County of York, Power Loom
Maker, do hereby declare the nature of this invention (which invention has been
communicated to me by George Frank Hutchins, of Worcester, in the County of
Worcester, and State of Massachusetts, United States of America, Power Loom Maker)
to be as follows :-
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 power swivel loom in which
the whole of the warp threads, or any portion of them, may be covered by the move-
ment 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 time of movement of
the swivel shuttles is indicated by the jacquard, so that they may be 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 desired.
For the purpose of carrying out my invention I employ a set of swivel shuttles
supported upon sliding fingers which act to separate certain portions of the warp
threads to allow the swivel shuttles to pass under such warp threads from one finger
to another finger. The swivel shuttles are adapted to be lowered into the shed and
arranged to separate and to contract portions of said warp. The fingers above
referred to are provided with pointed lower ends and will act to separate the said
warp, causing the said warp to extend between the fingers when they are lowered
into the shed.
I also employ a locking device for retaining the swivel shuttle in position upon the
fingers. The device consists of a spring and a ball supported on the said finger and
extended into a recess at the inner end of the swivel shuttle. I also employ in com-
bination with the swivel shuttle a removeable holder for supporting the spool or
bobbin independently of the shuttle.
Dated this 15th day of September 1897.

I, EDWARD HOLLINGWORTH, of Dobcross, in the County of York, Power Loom
Maker, do hereby declare the nature of this invention, (which invention has been
communicated to me by George Frank Hutchins, of Worcester, in the County of
Worcester, and State of Massachusetts, 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 attach-
ments, 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 power swivel loom in which
the whole of the warp threads, or any portion of them, may be covered by the move-
ment 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 time of movement of the
swivel shuttles is indicated by the jacquard, so that they may be 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 desired.
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 shown 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.

In the accompanying drawings, 1 are the loom sides or frames, 2 the arch stands, 3
the front arch, 3' 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 83 8¹ 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 shown
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 con-
nected by curved arms 22 to a lever 23 centrally pivoted 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 move-
ment 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
shown, through intervening inechanism, which is shown more particularly in
Figs. 2, 24, 14 and 15.
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 pivoted on the inner end of the arm 25
in the path of said cam 27, or with the finger 29 pivoted 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, pivoted at one end on the
arm 25, is raised or lowered by the cord 31, as shown in Fig. 2, and Fig. 2^.

page_text: A pin or stud 32 on the outer end of the sliding rod 19 extends into a diagonal
slot 2511 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
The cord 31 is connected through a spring 33 with the angle lever 34 pivoted 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.
arm 39 has a stud 40 extending out therefrom, on which is loosely mounted a
cam 41 having the two outwardly and downwardly extending arms 411. 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 pins 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 37, that when it is moved to one extreme position or the other on its
pivotal support, as shown 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 shown 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 44 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 shown.
I will now proceed to describe the swivel shuttle mechanism, and the operating
mechanism therefor shown 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 shown in Figs. 7 and 8, and having their lower ends 49¹ preferably
curved inwardly, as shown 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 of the shape shown 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 5311 comprising the central spindle 531 and two spiral springs 8 sur-
rounding the said spindle, as shown in Fig. 10, being used to keep the 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 shown 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 shown. The holder 52¹ extends in two
vertical grooves or recesses in the shuttle body, and is held therein. The advantages
of the holder 521 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.

page_text: The holder 521 has an opening 5211 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.
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 pivoted on
the fingers 49 by pins or studs 541, 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 are two levers 54 for each swivel shuttle 52.
The upper ends of said levers 54
extend loosely through slotted pins or studs 55 mounted to turn in the sliding bar 56,
and extending out from the front side thereof, see Figs. 6, 7, and 8.
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 a
groove or recess in the rear surface or back of the finger 49, and pressed into a
depression in the inner end of the neck of the shuttle by a spring 58 secured by
a screw 59 to the finger 49, as shown in Fig. 10.
Instead of using the swivel shuttles 52 of the shape and construction shown in
Figs. 6 and 10, I may use a swivel shuttle 60 of the shape and construction shown
in Fig. 9, and instead of using a ball 57 to hold the shuttle in position, I may use a.
spring actuated plunger 61 shown 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 har 56, and the parts
supported thereon, so that the swivel shuttles will be lowered into the shed, as shown
in Fig. 6, and raised out of the shed, in the operation of weaving the figures on the
under side of, or on both sides of the fabric, woven in the loom by the ordinary fly
shuttle mechanism, not shown.
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 bas a vertical motion,
and one of said rods 62 is pivotally attached to the front end of a lever 63, see
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 two
arined lever 66 centrally secured on 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 har.
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

page_text: 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 arm 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 mechanisin is
in operation.
When the picking rolls 16 are moved in the opposite direction to throw out of
action the fly shuttle mechanisın, the angle lever 69 through arm 73 will be moved,
and the arın 69¹ thereof raised, as shown 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 backward and forward
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 pivoted 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 both secured to the front ends
of the same 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 pulley or wheel 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 bub of cam pulley 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 ex-
tending 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 95¹ extending into an annular groove 96¹ in a pulley 96 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 9511 extending out therefrom, to 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 9511 is also attached the lower end of a cord 99, which leads over a
The other end of the
pulley 100 supported in this instance on the back arch 31.
cord 99 is attached to the rocking lever 37, see Figs. 1, and 16, 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 shown at the left in
Fig. 1, which have been already described, and similar letters are used to represent
similar parts. The additional locking mechanism shown at the left in Fig. 1 is not
shown in connection with the oscillating lever mechanism shown at the right in Fig. 1,
and also shown in Fig. 16, and only one locking stud or pin 42 is shown, the
spring 98 acting on cord 99 to hold the cam 41 in its opposite position. Cords 45¹
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 cam pulley 85 through lever 79, and communicate a longi-
tudinal motion to the sliding bar 56, to move the swivel shuttles controlled by the

page_text: 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 shown in Fig. 1, and thus
communicates to the cam pulley 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 can pulley 85 at rest.
The cam groove 85¹ in the pulley 85 is of such shape that a one-sixth revolution
of said can pulley, 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 shown in full lines Fig. 7 to the position shown 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 shows in plan the cam groove 85¹ in the pulley 85
shown in Fig. 17; supposing the pulley 85 to be revolving in the direction of arrow g,
the long portion of the cam groove marked X will carry the roll 84, shown 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 shown in
Fig. 7 to the position shown in Fig. 8. The cam portion Y in the continued revo-
lution of the cam pulley 85 will carry the roll 84 to the position O, and will move
back the levers 54 from the position shown by full lines Fig. 8 to the position shown
by dotted lines Fig. 8, and during the intermission of the movement of the cam
pulley, the swivel shuttles may be lowered into the shed for example, and after they
are lowered into the shed, the cam pulley 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 shown by dotted lines Figs. 8 to the position shown by full lines
Fig. 7. The continued revolution of the pulley 85 will cause the short cam portion M
to move the roll 84 to the position V, and the levers 54 from the position shown by
full lines Fig. 7 to the position shown by dotted lines same figure, and then the
movement above described will be repeated.
It is necessary to have the cam pulley 85 provided with a cam groove of such
shape that the levers 54 will be moved to throw the swivel shuttles in one direction,
and 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.
The connection of the pin wheel or other mechanism for operating the cam
pulley 85 with the jacquard, controls the movement of the swivel shuttles from
the jacquard, and tells when the swivel shuttles shall be moved to the right, or
the left, to carry the embroidering thread across the under side of the warp
threads, and across the upper side of the warp threads, to weave the spot or figure
on the under side of the fabric, or on the under and upper side of the fabric, as
desired.
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 shown 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 com-
municated to the cam pulley 85, and the swivel shuttles 52 are shifted, as above
described, for instance from the position shown in Fig. 7 to the position shown 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

page_text: "
disengagement of the pin wheel 91 from the star wheel 90 leaves the star wheel and
cam pulley 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 cam pulley 85 another partial revolution, which shifts the swivel shuttles from
the position shown in Fig. 8 to the position shown in Fig. 7, and they are then raised
out of the shed, and the filling put in as above described.
By this operation, the figures are woven only on the lower side of the fabric. To
weave the figures on both sides of the fabric alike, the cam 85 is operated from the
jacquard, which is properly punched, so as to lower the swivel shuttles into the shed,
shift them across the under surface of the warps extending up between the fingers 49,
raise them out of the shed, and shift them across the upperside of the warps, pre-
paratory to repeating the operation; while the swivel shuttles are being shifted across
the upper side of the warps, the fly shuttle is operated to put in the filling thread,
and while the fly shuttle mechanism is in operation, the arin 691 of the angle lever 69
will extend over the end 66¹ of the lever 66, to prevent said lever from moving, as long
as the fly shuttle mechanism is in operation, as above described.
In case there is to be plain weaving between the spots or figures then, through con-
nections 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 in, 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 and in what manner the same is to be performed, I declare that what I
claim is
1. In a power loom, a set of swivel shuttles supported by and sliding upon fingers,
which act to separate portions of the warp threads, to allow the swivel shuttles to pass
under said portions of warp threads, from one finger to another, substantially as shown
and described.
2. In a power loom, a set of swivel shuttles supported by and sliding upon fingers,
which are adapted to be lowered into the shed, and act to separate and contract por-
tions of the warp threads, to allow the swivel shuttles to pass under said portions of
warp threads from one finger to an adjoining finger, substantially as shown and
described.
3. In a power loom, the combination with a series of fingers which have a rising
and falling motion, and are provided with pointed lower ends which act to separate
portions of the warp threads and cause them to extend between the fingers when the
same are lowered into the shed, of a series of swivel shuttles supported on said
fingers, and adapted to be moved from one finger to an adjoining finger, and means
for moving said shuttles, substantially as shown and described.
4. In a power loom having a swivel shuttle attachment, the combination with a
series of fingers, and a set of swivel shuttles supported thereon, of a set of levers
pivoted on said fingers to engage said shuttles, and move them from one finger to an
adjoining finger, substantially as shown and described.

and adapted to be moved from one finger to an adjoining finger, of a locking device
for retaining the swivel shuttles in place upon the fingers, substantially as shown and
described.
7. The combination with a series of fingers and swivel shuttles supported thereon,
and adapted to be moved from one finger to an adjoining finger, of a locking device
for retaining the swivel shuttles in place upon the fingers, comprising a spring
actuated ball supported on said finger, and extending into a recess at the inner end
of the swivel shuttle, substantially as shown and described.
8. The combination with a series of fingers, and a set of swivel shuttles supported
thereon, and levers pivoted on said fingers to move said swivel shuttles, of mechanism
for moving said levers in one direction, then partially moving them in the opposite
direction, to move them out of the space between the fingers, substantially as shown
and described.

thereon, and levers pivoted on said fingers to move said swivel shuttles, of mechanism
for 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, consisting of
a cam and intervening connections to said levers, substantially as shown and
described.
10. In a power loom, the combination with a sliding pick mechanismın, of a locking
lever or device adapted to be moved into locking position to prevent the lowering of
the swivel shuttle into the shed, as long as the fly shuttle mechanism is in operation,
substantially as shown and described.
11. In a swivel shuttle loom, the combination with a supporting finger adapted to
be raised and lowered, of a swivel shuttle having its upper side open to receive the
spool or bobbin, substantially as shown and described.
12. In a swivel shuttle loom, the combination with a supporting finger adapted to
be raised and lowered, of a swivel shuttle supported on said finger, and extending
out therefrom in a substantially horizontal plane, substantially as shown and described.
13. The combination with a swivel shuttle, of a removeable holder for supporting
the spool or bobbin independently of the shuttle, said holder adapted to be combined
with the shuttle, substantially as shown aud described.
