Improvements in Swivel Looms for Weaving Spots or Figures of
One or More Colors.
I, EDWARD HOLLINGWORTH, of Dobcross, in the County of York, Machine
Maker, (which invention has been communicated to me from abroad by George
Frank Hutchins, of Worcester, Massachusetts, United States of America Machine
Maker) 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 :-
This invention relates to looms, and more particularly to swivel-looms-that is,
to those looms where, in addition to the ordinary fly-shuttle, swivel-shuttles are
used for the purpose of making spots or figures in the fabric.
The object of this invention is to provide a swivel-shuttle mechanism adapted to
be applied to the ordinary form of fly-shuttle loom, and which will automatically
weave spots or figures in the fabric produced in the loom, each spot or figure having
one or more colors of weft therein, as desired.
My invention consists in certain novel features of construction and certain novel
and improved combinations of parts, all as will be hereinafter fully described with
reference to the accompanying drawings, and there distinctly defined and parti-
cularly pointed out in the claims.
My improvements may be applied to any of the ordinary forms of fly-shuttle
looms and may co-operate therein with the usual operating mechanism of such
looms.
<
I have shown in the drawings my improvements applied to the well-known
Hollingworth" loom, the construction and operation of the characteristic features
of this loom being well known.
I have shown in the drawings only such parts of a Hollingworth loom having my
improvements applied thereto as is sufficient to clearly illustrate the application
and relations of my improvements.
Referring to the drawings,
Figure 1 is a front elevation of portions of a loom of the class referred to, provided
with my improved swivel-shuttle mechanism, parts of the said mechanism and of
the loom-frame being broken away.
Fig. 2 is a sectional elevation taken on line aa, Fig. 1, looking in the direction
of arrow a, same figure.
Fig. 3 is a detail view of a part of the swivel-shuttle weaving attachment, the
said figure shewing one of the cams hereinafter referred to, the pawl for actuating
the same, the pawl-operating crank, and the support on which the pawl slides.
Fig. 4 is a view similar to Fig. 3, but shews the pawl in the position which is
the opposite of that shewn in Fig. 3, said figure also shewing a lock-lever for
the cam.
Figs. 5, 6, and 7 are side and plan views of cams for changing the position of the
swivel-shuttle rail laterally in the loom, so that the spots produced shall be
arranged in the positions shewn in Figs. 8, 9, and 10, respectively.
Fig. 11 is a plan view of the upper part of the loom shewn in Fig. 1 looking in
the direction of arrow b, same figure, some of the parts being left off.
Fig. 12 represents, on an enlarged scale, a section on line y y, Fig. 1, looking
in the direction of the arrow c in the same figure, shewing the manner in which
the movable swivel-shuttle rail may be mounted on the hand-rail of the loom
and locked in position thereon, the swivel-shuttle rail being down in working
position.
Fig. 13 is a view corresponding to Fig. 12, but shewing the movable swivel-
shuttle rail locked in its upper position.

page_text: Fig. 14 is a front view in detail of the hand-rail and guiding and locking
devices for the swivel-shuttle rail, (not shown,) looking in the direction of arrow d,
Fig. 12.
Fig. 15 is a rear view of the devices shewn in Fig. 14.
Fig. 16 shews side view and also front view of the arm, which may be made fast
on the top of the movable swivel-shuttle rail and arranged to come into contact
with and rest on the hand-rail, as shewn in Fig. 2, to act as a stop in limiting the
downward movement of the said swivel-shuttle rail.
Fig. 17 is a view shewing a modification of the mechanisms shewn in Figs. 3
and 4 for shifting the swivel-shuttle rail laterally in the loom.
Fig. 18 is a view shewing a modification having one set of swivel-shuttles, which
are placed in a horizontal position in the ordinary way, instead of in a vertical
position; and
Fig. 19 is a view shewing a modification of the indicating mechanism shewn in
Fig. 1.
Figs. 3 to 18, inclusive, except Fig. 11, are on a larger scale than the other figures.
In the accompanying drawings, 1 are the loom sides; 2, the vertical pawls;
3, the front top rails; 4, the slay board; 5, the slay swords; to the top of which
is bolted the hand-rail 6; one set of fly-shuttle boxes is shewn at 7, the other
set not being shewn; 8, is the lifting-rod for operating the shuttle-boxes; 9, the
bottom shaft of the loom, and 10 the crank-shaft. 11 and 12 are spur wheels
whereby said shafts are geared together, and 13 are the picking-shafts, which
extend at right angles to the bottom shaft 9 and carry the picking-shoes 14, the
latter being operated upon by the bowls 15, carried by the arms 21 on the bottom
shaft 9 in the ordinary way.
In the drawings I have shewn devices for moving the picking-bowls 15 into and
out of engagement with the picking-shoes 14, as shewn by full and dotted lines, in
Fig. 1, the said devices consisting of sliding rods 16 and 17, supported and sliding
in stands 18 and 18', with their inner ends connected by curved arms 19¹ to a lever 19,
pivoted on the central stand 18¹. In consequence of being connected by the said
arms 19 to the opposite arms of the lever 19, the said sliding rods, when they are
actuated in a manner to move them endwise, are caused to slide simultaneously
in opposite directions. Thus, the parts being in the position in which they are
represented in Fig. 1, if rod 16 is drawn to the left-that is, away from the middle
of the loom-the rod 17 will be moved toward the right--that is, also, away from the
middle of the loom. In like manner, whenever either of the said rods is moved toward
the middle of the loom the other thereof, also, will be moved simultaneously therewith
in the opposite direction-that is, also, toward the middle of the loom. The said
rods 16 and 17 carry forked arms 20, each of the said forked arms being adapted
to engage with the grooved hub 21' of one of the castings 21, carrying the bowls 15,
said castings 21 being supported on the bottom shaft, so as to slide thereon and
revolve therewith, and being provided with projecting pins 211, which slide freely
in corresponding channels in the hubs 9', fast on the bottom shaft 9. The sliding
rods 16 and 17 are operated to move them outwardly from the middle of the loom,
and thereby carry the picking-bowls 15 into position for coming in contact with
the picking-shoes 14 by means of a cord or chain 631, to be hereinafter described,
secured to a collar 23, jast on the sliding rod 16. (See Fig. 1.) The operation of
said cord is controlled by a cam forming a part of my improvements, to be herein-
after described. In the present instance the picking-bowls 15 are moved out of
engagement with the picking-shoes 14 by means of a spring 24, fast at one end to
the central stand 18' and at the other end to a collar 25, fast on the sliding rod 17.
When the cam which moves the lever to which the cord 63' is connected permits
the spring 24 to act, the said spring operates to move the rods 16 and 17 inwardly
toward the middle of the loom, thereby carrying the bowls 15 into the position
in which they are represented in Fig. 1. If desired, the picking-bowls 15 may be
given a positive motion in the direction to carry them out of engagement with the
picking-shoes by means of a second cord or chain 22', (see Fig. 1) corresponding

page_text: to cord 631, secured to the collar 23 on the sliding rod 16 and operated from the':
same lever which operates the cord or chain 63¹, to be hereinafter described.
The head of the loom is of the ordinary construction and operation, and consists
of the upper cylinder-gear 26, the lower cylinder-gear 27, vibrator-gears 28,
vibrator-levers 29, a system of gears at the upper end of the upright shaft 30
(shewn in dotted lines in Fig. 1) for operating the cylinder gears, and a system of
gears at the lower end of said shaft 30 (shewn by dotted lines in Fig. 2) for
operating said upright shaft 30, the last-mentioned system of gears being driven
by the crank-shaft 10 in the ordinary way. Crank-connectors 31, one of which is
shewn in Fig. 2, connect the crank-shaft with the slay, as usual.
The foregoing parts and the usual working parts of a loom, which are not shewn,
are or may be constructed and operated in any desired or known manner.
I will now proceed to describe my improvements, in this instance adapted to be
combined with the parts of the loom above described, so as to automatically weave
spots or figures having one or more different colors. In my improvements three
sets of swivel-shuttles are used to weave the spots or figures in the fabric; but only
one set of swivel-shuttles may be used, or more than three sets may be used with
practically the same mechanism. The operating-cams and pawl connections of my
swivel-shuttle mechanism are preferably located at the upper part of the loom
back of the harnesses and head motion, so as not to interfere with the ordinary
construction and arrangement of the same. Upon the top of the back arch 3 is
bolted a stand 32, extending at the rear of the loom, upon which are supported the
cams and other parts of my mechanism. A stud or shaft 33 is fast in stand 32, and
on said stud are supported, to revolve loose thereon in this instance, five cams,
which are used to operate the several parts of my mechanism, three of which
cams 34, 35, and 36 operate through intervening connections, to be hereinafter
described, the three swivel-shuttle racks 76, supported in the swivel-shuttle rail 75,
to be hereinafter described, and which operate the three sets of swivel-shuttles 77,
which weave the spots or figures in the fabric. The fourth cam 37 of said five
cams, through intervening connections, changes the position of the swivel-shuttle
rail 75, carrying the longitudinally swivel-shuttle racks 76, so as to place the spots
or figures woven in the position shewn in Figs. 8, 9, and 10 or otherwise, as
described, according to the shape of said cam. The fifth cam 38, through inter-
vening connections, operates the sliding picking devices to cause the loom to pick
or to stop picking, as desired, and also at the same time raises or lowers the swivel-
shuttle rail 75 to prevent the swivel-shuttles 77 from operating or to allow them to
operate to weave the spots or figures. In this instance on one end of the shaft 39
of the upper cylinder-gear 26 is fast a wheel 40, which meshes with and drives a
wheel 41, fast on a shaft 42, supported in stands 42', bolted on the top of the loom-
arches. On said shaft 42 is secured a double crank 43, (see Figs. 3, 4, and 11,) one
arm 43 of which is connected to one end of the horizontal pawl 45. The free end
of said pawl 45 is provided with a pin 45', adapted to engage the notches 38¹ in the
periphery of the cam 38 above described. The other arm 43" of the double
crank 43 is connected by means of a pin 44 with the rear ends of the four pawls 46,
the free ends of said pawls being provided with pins 461, adapted to engage the
notches in the peripheries of the cams 34, 35, 36, and 37, respectively. The
notches in the periphery of the cams 34, 35, 36, 37, and 38, with which the pins,
projecting from the free ends of the pawls 45 and 46 engage, are preferably made
of the shape shewn in the drawings, (see Figs. 3 and 4,) each having the contracted
opening at the outer end thereof. The object of making the notches in said cams,
as above described, is that in case for any purpose the loom is turned backwards
the pawls will not be disconnected from their cams, but will push the cams back
to their former positions, and thus keep all the parts in unison with each other. In
connection with the pawls 45 and 46, which operate the cams, a stationary rod or
pin 47 is used, which extends at right angles to the pawls, and in this instance is
supported in the upturned arms 321 of the frame 32. The rod 47 may have friction
rings or washers thereon, if desired. The object of the rod 47, in connection witho

page_text: the cam-section of the pawls, is to operate as a fulcrum for the pawls. I have
shewn in the drawings the pawls 45 and 46 provided with curved or cam portions
about the middle of their length, the object of which is to reduce the upward
motion of the free end of said pawls and to prevent said ends from being thrown
up as much as they would be if said pawls were made straight throughout their
length. I do not limit myself to the use of pawls provided with cam-surfaces.
As the cranks which operate the pawls continue to revolve after each crank-arm
has reached nearly the end of its throw, as shewn in Fig. 4, (carrying down the
attached end of the pawl with it,) the rod 47 will act as a fulcrum and cause the
pin on the free end of each of the pawls to be raised out of the notch in the corre-
sponding cam and be disengaged therefrom. The continued revolution of the
crank will push the pawl forward and the pin in the end thereof will engage
another notch in the cam when the crank is in the position shewn in Fig. 3. By
means of the shape of the notches in the cams (which are equivalent to teeth in a
ratchet-wheel) and the use of the rod 47, in connection with the cam-sections of the
pawl, it will be seen that the loom can be turned backward to the extent of a
partial revolution of the crank-shaft thereof and then moved forward without dis-
connecting the pawls from the cams which they operate. This is an important
feature in looms. The pawls 45 and 46 are preferably guided through slots in a
guiding-plate 48 on the upper part of stand 32. The pawls 46 and pawl 45 are
preferably adjustably connected with links 44', extending from the crank-arms 43,
(see Figs. 3 and 4) so that said pawls may be slightly lengthened or shortened, if
desired. Said links 44' are provided with slotted ends, and clamps 44 thereon
provided with set-screws 441 Into said clamps 44" extend the rear ends of the
pawls 45 and 46, which are held and adjusted therein by means of the set-
screws 44. I have not shewn in Fig. 11 the links 44', referred to above, as said
links may be used or not, as preferred, in connection with the levers 45 and 46.
Springs 49, attached at their upper ends to the pawls and at their lower ends to
the loom-arch, are preferably employed to draw down the free ends of the pawls,
so that they will engage the notches in the peripheries of the cams at the proper time.
The operation of the pawls 46 and 45, is controlled by indicating-levers 50, one
for each pawl and cam. The levers 50 are pivoted at one end on a pin 51' in an
upright arm 51 of the stand 32. (See Figs. 1 and 19.) The free ends of the
levers 50 extend between the cams and under the free ends of the pawls 45 and 46.
(See Fig. 11.) When the free ends of the levers 50 are raised, as shewn by full
lines, Fig. 19, the free ends of the pawls will ride on said levers and the pins on
the pawls will not engage with the notches in the cams to operate said cams.
When the free ends of the levers 50 are dropped down, as shewn by dotted lines,
Figs. 1 and 19, the pins on the free ends of the pawls will engage with the notches
in the cams and operate said cams.
I have shewn in Fig. 1 one way of operating the indicating-levers 50. I use a
cam-wheel 52, operated by a jacquard cord 53, through intervening mechanism,
consisting of a lever 54, carrying a pawl 55, adapted to engage with and operate a
ratchet-wheel 56, fast on the shaft of the cam-wheel 52. The jacquard cord 53
operates the lever 54 loose on the shaft of the cam-wheel 52 and carrying the
pawl 55. This pawl 55 engages with the teeth of the ratchet-wheel 56, and causes
said cam-wheel to revolve and operate the indicating-lever 50.
In lieu of a cam-wheel any kind of a cam or a wheel or other mechanism which
will effect the indications from jacquard cords or harness-cords may be substituted.
I have shewn in Fig. 19 a simple modified mechanism for operating the indicating-
levers 50, consisting of a weighted lever 110 raised by jacquard cord 110 having a
cam projection 110 thereon adapted to engage the projection 111 on the lever 50
and hold said lever in its raised position. A pawl 112, pivoted on a pin 113,
engages a notch in the weighted lever 110 and holds up said weighted lever in
the position shewn. A second weighted lever 114 (shewn in its downward position)
has a cam-surface 114' thereon, which when said lever 114 is raised by the jacquard
cord will engage a pin 115 on the pawl 112 and trip said pawl and allow the

page_text: weighted lever 110 to fall, disengaging the projection 110¹ thereon from the
projection 111 on the lever 50 and allowing said lever to fall, as shewn by dotted
lines, Fig. 19. The second weighted lever 114 and the pawi 112 may be dispensed
with and only the weighted lever 110 used to operate the indicating-lever 50.
The raising of the lever 110 will raise the lever 50 and the dropping of the
lever 110 will allow the lever 50 to drop. I preferably employ a holding or locking
lever 57, one for each cam, (see Figs. 1 and 4,) the upper end of which is adapted
to enter the notches in the periphery of the cams to hold the same steady when not
in motion. The lower end of said lever is provided with a spring 58, adapted to
draw over the upper end of said lever and cause the same to engage with the cam.
I also employ a holding-lever 591, with its upper end adapted to engage with and
hold the cam-wheel points of the cam-wheel 52 and the lower end connected with the
spring 58 for holding said lever in engagement with said cam-wheel. (See Fig. 1.)
Having described the mechanism for operating the cams 34, 35, 36, 37, and 38,
I will now proceed to describe the mechanisms operated by said cams for, first,
shifting the swivel-shuttle racks; second, changing the position longitudinally of
the swivel-shuttle rail carrying the racks, and, third, lowering and raising said
swivel-shuttle rail and at the same time operating the sliding pick device to cause
the loom to weave the spots or figures in the fabric, or not to weave them, as
desired. On a rod 60", supported in the upright part of the stand 32, (see Figs. 1
and 2,) are hung the vertical levers 59, 60, 61, 62, and 63, one for each of the
cams 34, 35, 36, 37, and 38, respectively. Each of said levers is provided with an
arm extending out therefrom, carrying a pin or bowl adapted to extend into the
groove in the inner face of the respective cam. The shape of said cam-groove
conforms to the desired movement to be given to each of said levers. The three
rear levers 59, 60, and 61 are connected at their lower ends with two sets of
cords 591, 60', and 61', which pass around two sets of sheave pulleys 67, 68, and 69,
(see Fig. 1,) supported on extensions 94 on the rear or inner ends of the horizontal
hinged arms 73. (See Fig. 11.) From said sheaves 67, 68, and 69 the cords pass
over two sets of sheaves 70, 71, and 72, (see Figs. 1 and 11,) supported on the
forward or outer ends of the two arms 73. The said arms 73 are hinged at their
rear or inner ends on stand 94', secured to the rear loom-arch and extend out under
the loom-arches at each end of the swivel-shuttle rail. (See Fig. 11.) To the
forward or outer ends of the two swinging arms 73 are hinged the two vertical
swinging arms 74. The two pairs of arms 73 and 74 form a freely-swinging frame,
supported over the slay, said frame being capable of being raised and lowered and
of being moved from side to side or longitudinally relatively to the slay.
lower part of said swinging frame is supported the movable swivel-shuttle rail,
carrying the swivel-shuttles to be hereinafter described. On the lower ends of the
vertical arms 74 is pivoted by pins 66 the swivel-shuttle rail 75, carrying in this instance
the three swivel-shuttle racks 76 operating the three sets of swivel-shuttles 77 only
one of the swivel-shuttles being shewn in Fig. 1; also, at the lower ends of the
vertical arms 74 are supported the two sets of sheaves 78, 79, and 80, (see Figs. 1
and 2,) over which pass the cords 591, 60¹, and 61', one pair of cords for each swivel-
shuttle rack, and the ends of each pair of cords are detachably connected with pins
or eyes 81 in their respective swivel-shuttle rack 76. (See Fig. 1.) It will thus
be seen that the swivel-shuttle racks 76, for operating the swivel-shuttles, have a
positive motion in either direction through the cords 59, 60', and 61' and the
levers 59, 60, and 61, operated by the cams 34, 35, and 36, respectively. To the
end of the lever 62 are attached cords 62', which pass over the sheaves 82, 83,
and 84, (see Figs. 1, 2, and 11,) supported alongside of the sheaves above described,
to the swivel-shuttle-rail-supporting stands 85, hinged on the upper side of the
hand-rail 6. (See Figs. 1, 12, and 13.) The motion of the lever 62, will cause
the swinging arms 74 to move in one direction or the other and carry with them
the swivel-shuttle rail 75 and move it to change its position longitudinally or
relatively to the width of the fabric, according to the shape of the cam operating
said lever 62, so as to place the spots woven by the swivel-shuttles in the different
In the

page_text: positions desired. It is to be observed that the stands 85 are, so to speak, fixtures
upon the hand-rail, and that therefore when the lever 62 is moved in one direction
or the other one of the cords 621 will be so tightened up around the sheaves 82 83
84 as to cause the swinging arms 74 to move laterally in the direction of the strain.
While the swivel-shuttle rail is depressed into the position which it occupies while
the swivel-shuttles 77 are running, the pick mechanism must be disconnected, and
this is accomplished by means of the lever 63, operated by cam 38, and the cord 63¹,
which is connected with the said lever 63 and passes over the sheave 86, supported
on a stand 95 on the loom-arch, (see Figs. 1 and 11,) and over the sheave 86', at
the bottom of the loom and is connected to the collar 23 on the sliding shaft 16.
The sliding pick device will thus be operated by the lever 63, according to the
formation of the cam 38, which controls the operation of said lever. In arms 87,
upon the top of the front loom-arch, (see Figs. 1, 2, and 11,) is supported a rocking
shaft 88. On one end of said rocking shaft 88 is fast an arm 89. To the outer
end of said arm 89 is attached the end of a cord 90, which passes- around the
sheave 91 on the stand 95, and is attached to or forms a part of the cord 63¹ at a
point 90', (see Fig. 1,) leading from the lower end of the lever 63, as before stated;
also fast on the rocking shaft 88 are the two arms 92, to the outer ends of which
are attached cords 93, with their lower ends attached to the outer ends of the
horizontal arms 73. Said cords 93 serve to hold the horizontal arms 73 in proper
position, so that the swivel shuttle rail 75, carrying the swivel-sbuttle racks 76 and
swivel-shuttles 77, will be supported in its proper position above the slay 4, and
when the swivel-shuttles for weaving the spots are not in use they will be raised up
from the slay by means of said cords 93, arms 92, rocking shaft 88, arm 89, and
cord 90, attached to the cord 63¹, connected with the lever 63. It will thus be
seen that the lever 63 when moved in one direction operates, both the shipping
devices for the fly-shuttle picking mechanism and the swivel-shuttle rail, causing
the said swivel-shuttle rail to be lowered into position for the swivel-shuttles to run
and the picking motion for the fly-shuttle to be disconnected, and when the said
lever 63 is moved in the opposite direction the swivel-shuttle rail is raised from the
slay and the picking motion is connected, so as to operate the fly-shuttle. By this
construction the fly-shuttle-picking motion of the loom must be disconnected when
the swivel-shuttles are in position for running, so that there can be no danger of
breakage or damage from the accidental operation of the fly-shuttle.
I will now describe more particularly my improvements relating to the movable
swivel-shuttle rail carrying the swivel-shuttles and the manner of attaching the
same to the hand-rail. The swivel-shuttle rail 75 is supported over the slay
independently of the hand-rail 6 by means of the vertical arms 74, as above
described, so that said swivel-shuttle rail 75 may be raised and lowered for moving
the swivel-shuttles out of action or moving them into action, and said swivel-shuttle
rail may also be moved longitudinally relatively to the hand-rail to change the
position of the spots or figures by means of the cams and connections thereto above
described. The swivel-shuttle rail 75 consists of the rail proper, having supported
therein the three racks 76, which extend parallel to each other and which have a
reciprocating longitudinal movement in slots in the swivel-shuttle rail by means of
cords attached to the eyes 81, secured in said racks, as above described. The
racks 76 operate three sets of pinions 97, mounted loosely on pins 98, fast in the
lower part of the swivel-shuttle rail 75 in the ordinary way. (See Fig. 12.) The
pinions 97 operate the three sets of swivel-shuttles 77, extending in a vertical
position in three rows, as fully shewn in Fig. 12. By using two or more sets of
swivel-shuttles arranged as above described for weaving each spot or figure in the
fabric, I am enabled to put into each spot or figure two or more different colors,
according to the number of sets of swivel-shuttles used. Each set of swivel-
shuttles is provided with a different color of weft, if desired. I prefer to connect
the swivel-shuttle rail 75 with the hand-rail 6, so that said swivel-shuttle rail may
be held against the hand-rail 6 during the operation of the swivel-shuttles by means
of the two U-shaped stands 85. (See Figs. 12 and 13.) The swivel-shuttle rail 75

page_text: is adapted to move up and down and also longitudinally within the U-shaped
stands 85, the sides of which act as bearings for the sides of the swivel-shuttle rail
as said shuttle-rail is raised from the slay or lowered toward the slay for the
swivel-shuttles to operate. The U-shaped supporting-stands 85 of the swivel-
shuttle rail are preferably each hinged at their rear upper part by means of a
pin 99, supported in the upper part of an arm 100, rigidly secured at its base on
top of the hand-rail 6. The arm 100 is provided with projections or ears 100¹ 100",
and supported on the rear side of the U-shaped stand 85 is a lock-lever 101, pivoted
on pin 102 in said stand. Said lever 101 is adapted to be raised to a vertical
position, as shewn by dotted lines, Figs. 14 and 15, to disconnect the same from
the projections on the arm 100 and allow the stands 85, within which the swivel-
shuttle rail 75 extends, to be freely raised or lowered on their hinged point. When
the U-shaped stands 85 are lowered, as shewn in Fig. 12, the lock-lever 101 is moved
down in front of the upper projection 100", as shewn in Figs. 12 and 15, thus
locking the stands 85 and preventing any movement of the same on their hinged
point. When the stands 85 are raised up, the locking-lever 101 is moved down
under the projection 100¹ of the arm 100, as shewn in Fig. 13, thus locking the
stands having the swivel-shuttle rail 75 supported therein in their raised position.
The object of having the stands 85, within which the swivel-shuttle rail 75
extends, hinged to the hand-rail 6 is to allow of the swivel-shuttle rail 75 being
tilted or raised up so as to readily get at the bobbins in the swivel-shuttles, and the
object of the locking mechanism is to rigidly support and lock the swivel-shuttle
rail and swivel-shuttles in their normal position extending alongside of the hand-
rail or to hold and lock them in their raised position, for the purpose above stated.
When the swivel-shuttle rail 75 is raised up, as shewn in Fig. 13, if it is desired to
get at any one of the two inner or lower sets of swivel-shuttles to remove an
empty bobbin and substitute a fresh bobbin the ends of the connections or cords 59¹,
60, and 61 are disconnected from the pins or eyes 81 in the swivel-shuttle racks,
and then the swivel-shuttle racks are moved by hand, so that the swivel-shuttles to
be got at will be moved into the warp or open space in said rail, as shewn in
Fig. 1, allowing free access to the bobbin in the swivel-shuttle and the ready
removal of the same and the substitution of a fresh bobbin. Upon the top side
of the swivel-shuttle rail 75 are secured in this instance two bent arms 107, with
their projecting ends 107' adapted to rest on the hand-rail 6, as shewn in Fig. 2,
to support the swivel-shuttle rail 75 and limit the downward motion thereof.
Referring to Fig. 18, the stand 85, within which the swivel-shuttle rail 751
extends, is rigidly connected with the hand-rail 6' for the reason that the swivel-
shuttle extends in a horizontal plane, and therefore it is not necessary to tilt the
shuttle-rail to get at the bobbin in the swivel-shuttle.

In Fig. 17 I have shewn a modification of the cam-lever shewn in Fig. 1. I
provide a second lever 103, pivoted on the stand 32 and provided with a longi-
tudinal slot 104 therein. A connector 105 extends from the lower end of the
cam-lever 63 to the slot 104 in the lever 103. Said lever is adjusted up and down
in said slot and retained in place by means of a screw (not shewn) to vary the
travel or amount of motion of said lever 103, to the lower end of which are
attached the cords leading over the sheaves to operate the racks or to move the
swivel-shuttle rail longitudinally. It will thus be seen that without changing the
shape of the cam I can vary the amount of travel of the lever 103 and the con-
nections thereto.
From the above description, in connection with the drawings, the operation of
my improved swivel-shuttle mechanism will be readily understood, and the
advantages of my improved swivel-shuttle mechanism will be readily appreciated
by those skilled in the art. I provide one or more sets of swivel-shuttles, arranged
in lines parallel to each other, extending over the race, all of which are operated
automatically and each set independently. I am thus enabled to put into each
spot or figure in the fabric one or more different colors, according to the number of
sets of swivel-shuttles used. It will be understood that the details of construction
