Specification of Letters Patent.

Patented Feb.17,1914.

Application filed September 28, 1907. Serial No. 394,996.

To all whom it may concern.

Be it known that I, FREDERICK F. Rooms, of Lincoln, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Swivel-Looms; and I do hereby declare the following specification, taken in connection with the accompanying drawings, forming a part of the same, to be a full, clear, and exact description thereof.

The invention relates to swivel looms adapted to'weave figures in the fabric by means of swivel shuttles.

In another application of even date herewith I have shown and described a swivel loom adapted to produce such swivel figures which will appear on one side of the fabric only, or on both sides of the fabric, as may be desired. \Vith the construction shown in said application the oscillating movement of the swivel shuttles in each direction takes place during the backward swing of the lay. One result of such construction is that when it is desired that theswivel figures shall appear on both sides of'the fabric it is necessary that there shall be a lost pick, that is, a pick at which no weaving is done, between the oscillating movement of the swivel shuttles in one direction, and the oscillating movement of the swivel shuttles in the opposite direction. Moreover with said construction two jacquard cords are required for controlling the oscillating movements of the swivel shuttles, one jacquard cord being required to control the oscillating movements of the swivel shuttles in one direction, and another jacquard cord being required to control the oscillating movements of said shut-- ties in the opposite direction. 1

One objectof the present invention is to provide means whereby one of the oscillating movements of the swivel shuttles may take place during the forward beat of the lay, and whereby swivel figures which appear on both sides of the fabric may be pro duced without any lost pick, thereby saving the time incidentto such lost picks.

Another object of the invention is to provide means whereby the oscillating movements of the swivel shuttles in both directioias may be controlled by a single jacquard cor Another object of the invention is to provide means whereby the mechanism for effooting the oscillating movements of the swivel shuttles will operate easily and without shock or jar to the cooperating parts.

The invention consists primarily in providing means for causing one of the oscillatmg movements of the swivel shuttles to take place during the forward beat of the The invention further consists in providing means whereby the oscillating movements of said shuttles in both directions will'be caused to take place at one and the same pick of the loom, the oscillating movement of said shuttles in one direction taking place during the backward beat of the lay and the oscillating movement of the shuttles in the opposite direction taking place during the forward beat of the lay at the same pick.

The invention further consists in providing means whereby the oscillating movements of the swivel shuttles in both directions are controlled with the employment of only one jacquard cord.

The invention further consists in certain combinations and arrangements of parts hereinafter described and claimed.

Referring to the drawings, Figure 1 is a front elevation of a loom provided with my improved swivel shuttle mechanism, parts of the mechanism and of the loom-frame being broken away. Fig. 2 is an end elevation of the left hand end of the loom, at which the major part of the swivel shuttle mecha-.

nism is located. Figs. 3 to 8 inclusive are details of different parts of the mechanism.

In the accompanying drawings, 1 represents the loom-frame, 2 the lay, 3 the layswords, l the hand-rail, 5 the main or fly shuttle-boxes, 6 the main or crank-shaft, and 7 the cam-shaft of the loom, all of the above parts'being of the usual or any desired constructions.

I'Vhen the swivel figures are to be woven in the fabric it is necessary to prevent the operation of the main shuttle, and also to move the swivel shuttles into operative position. In the present construction both of these operations are controlled by one and the same jacquard cord. The mechanism for performing these two operations and the manner of controlling such mechanism by the jacquard cord will be first described.

In the construction shown the means employed for controlling the operation of the main shuttle involves means for shifting the position of the pickingrolls on the camshaft, and so as to move said picking-rolls into and out of engagement with the picking-shoes on the picking-shafts.

Referring to Fig. 1, 8 represents the picking-rolls mounted on the cam-shaft 7 so as to be capable of sliding thereon. The two sets of picking rolls 8, one at each side of the loom, are arranged to be moved simultaneously toward and from each other, and so that they will be simultaneously moved into and out of engagement with their respective picking shoes 9. The mechanism for thus shifting the picking rolls 8 is similar to that shown in Letters Patent No. 474,170, up to a certain point, and it. will therefore only be necessary to describe in detail the means employed for shifting the shipper rod 10, it being understood that the companion shipper rod 11 will be operated by the shipper rod 10, but in the reverse direction.

In the construction shown the shipper rods 10 and 11 are arranged to be moved in a direction to bring the picking rolls 8 in line with the picking shoes 9 by means of a jacquard or other pattern mechanism, and to be moved in a direction to move the pickingro'lls out of line with the picking shoes by means of the spring 12, one end of which springis connected to one of said shipper rods, the other end of said spring being connected to the other shipper rod. Pivoted on a stud l3 projecting from a bracket 14 secured to the frame is a ,bell crank lever 15 provided with. an elongated hub. To one arm 16 of said lever is attached the jacquard cord 17, which, itwill be understood, leads to a jacquard mechanism, not shown. The otherarm 18 of said lever is connected by means of a linkor connecting rod 19 to one arm 20 of a bell-crank lever suitably pivoted on a stud 21 projecting from a bracket 22 secured to the frame. The other arm 23 of said last mentioned lever is provided with an elongated slot 24, into which slot extends a pin 25 projecting from the shipper rod 10.

As will be seen, whenever the jacquard cord 17 is raised it will serve to turn the bellcrank lever 15 and, through the connecting rod 19, to turn the bell crank

lever

20, 23, and soas to thereby move the shipper rod 10 lengthwise against the action of the spring 12.

The swivel shuttle bar 26, in which the swivel shuttles 27 and the rack and pinioiis for operating said swivel shuttles are carried, is mounted on the lay so as to have both an up and down movement, and also a longitudinal movement, that is, amovement crosswise of the loom. Secured to the upwardly projecting lay-sword horns 28 are two upwardly extending U-shaped brackets 29, one at each side of the loom. Each of said brackets 29 is provided with a slot 30,

in each of which'slots is mounted a guideblock 31. Each guide-block is provided with a projecting bearing 32 to receive the short rod or bar 33 secured to the end of the swivel shuttle-bar 26. Also connected with the swivel shuttle bar is a giiide-rod 34 which extends across the loom, the ends of said guide-rod extending through and being supported in bearings 35 formed in brackets 36 projecting rearward from the sliding blocks 31. With this construction the swivel shuttle bar 26 may have an up and down movement imparted to itby moving the vertically sliding blocks '31 in the slots 30, and

may have a longitudinal movement imparted to it in one direction or the other by the sliding of the rods 33 and the guide-rod 84 in their respective bearings.

The up and down movements of the swivel shuttle bar to move the swivel shuttles into and out of operative position are imparted thereto by means of 'the vertically moving rods 3?. The niechai'iisni for giving the necessary up and down movements to said ocls3'i', and for determining the times when such niovements sh all take place, is as follows: Secured to the frame at each side of the loom isa cam 38,"and to each of the rods 37 is secured a friction-roll 39 adapted to engage said cam 38. The construction and location of the camsj38 are'siich that, as long as the rods 37are free to move iipand down, said rods and the swivel shuttle bar supported thereby will bemoved up "and down'at each forward and back motion of the lay by the riding of the rolls 89 up and down the cams 38. As will be seen, the swivel shuttle bar will be raised to its upper or lHO PQI'HtlVG position at each forward beat of the lay, and will be allowed to fall to its lower or operative position at each backward swing of the lay.

Vilhen the plain fabric is to be woven the swivel shuttle bar is to be held in its upper or inoperative position, and in the construction shown the holding of said swivel shuttle bar in its 'iipper position isnot only controlled, but is effected, by the jacquard cord 17, whichcord also effects the throwing-out of the main shuttle picking mechanism. Connected to the end of the shipper rod 10 by a suitable joint is a link 40, the other end of which link is connected to the arm 41 of a bell-crank lever pivoted 'to the frame. Connected to the aim 44 of said bell-crank lever is a link or connecting rod 45, which said link is in turnconnected to the end of an. arm 46 projecting from a rock-shaft- 47.

Said rock shaft 47 extends across the loom and is provided at each end'witli a. projectarm 48. The lower ends of the vertically movingrods 37 are connected one to the end of each of said arms 48. The lowerend of the link or connecting rod 45 is provided with an elongated slot 49, in which slot the iio connecting pin 50 which connects the arm 46 to said link 45 may play. Vith this construction it will be seen that when the shipper rod 10 is in the position to hold the picking rolls 8 in line with the picking shoes 9, and so that the main shuttle will be operated thereby, the link or connecting rod 45 will, by reason of its connections with said shipper rod 10, be held in its lowermost position, and that when said link or connecting rod 45 is thus held in its lowermost position, the vertically moving rods 37, and the swivel shuttle bar 26, will, by the intermediate connections, be held in their uppermost position, and so as to thereby hold the rolls 39 on said rods 37 entirely above and'out of engagement with the cams 88, theswivel shuttle bar being thereby held in its upper or inoperative position by the jacquard cord 17.

The operation of the mechanism above described for throwing the main shuttle out of operation and moving the swivel shuttles into operative position when the figures are to be woven in the fabric is as follows: During the plain weaving the picking rolls 8 are in line with, and in position to operate, the picking shoes 9, and thereby operate the main shuttle. So also during plain weaving the swivel shuttle bar 26 will be held in its upper or inoperative position, said picking rolls and said swivel shuttle bar being held in such positions, bythe jacquard cord 17 and the intermediate,connections above described, against the actionof the spring 12 which is under tension at this time. hen now the figures are to be woven in the fabric the jacquard cord 17 is released by the jacquard mechanism, and so that the spring 12 will be thereby permitted to operate, the operation of which spring serves to move the shipper rods 10 and 11 in opposite directions, and so as to move the picking rolls 8 at opposite directions of the loom inward or toward each other, and so as to move said picking rolls out of line with their respective picking shoes 9, and thereby prevent the operation of the main shuttle. The movement of the shipper rod 10 in the direction referred to will serve to operate the bell crank

lever

41, 44, and thereby move the link or connecting rod 45 upward.

As the swivel shuttle bar 26 was held in its upper position by the engagement of the pin 50 with the upper end wall of the slot 49 in said rod 45, it will be seen that as said rod 45 is moved upward the swivel shuttle bar will be permitted to fall under its own weight and the weight of the parts connected thereto, and it will be understood that the falling movement of the swivel shuttle bar thus permitted is to be sutficient to bring the rolls 39 into position to engage and be operated by the came 38 as the lay swings forward and back. The up and down'movements of the swivel shuttle bar during the weaving of the figures, under the action of the rolls 39 and the cams 38, is permitted by the slot 49 in the connecting rod 45, which slot permits the up and down movements of said swivel shuttle bar without any corresponding movement. of said rod 45.

When now the weaving of the swivel figures has been completed and plain weaving is to be resumed, the jacquard cord 17 is operated to return the shipper bar 10 to its original position, and so as to bring the picking rolls 8 in line with the picking shoes 9, and so that the main or fly shuttle will againbe thrown into operation. Such movement of the shipper rod 10 will, through the action of the bell crank lever 41, serve to depress the rod 45, and thereby depress the arm 46 and correspondingly raise the arm 48 and the rods 37 connected thereto. This will serve to raise the rolls 39 on said rods above the cams 38, and so that said rods 37 will no longer be operated by said cams. The swivel shuttle bar will thus be held in its upper or inoperative position by the jacquard cord 17, and will remain thus held until said jacquard cord is again released. It will thus be seen that the throwing of the main shuttle into and out of operation, and the movements of the swivel shuttle bar into and out of operative position, are both controlled and effected by one and the same jacquard cord, and it will-be further seen that the construction of the parts and the timing of their movements are such that the main shuttle will be sure to be thrown out of operation before the swivel shuttles can be operated, and that, on the other hand, the swivel shuttles will. be thrown out of operation before the main shuttle can be operated.

The mechanism for operating the swivel shuttles to lay the swivel threads will next be described. In the construction shown in the drawings the swivel shuttles have an oscillating movement imparted thereto in the arc of a circle by means of a rack-bar 51 arranged to slide in the swivel shuttle bar, which said rack-bar engages pinions 51 which said pinions in turn engage horseshoe-gears 52 connected with the swivel shuttles.

In the construction shown in the drawings the means for operating the rack-bar to oscillate the swivel shuttles is especially adapted for weaving the figures on both sides of the fabric, and a characteristic and important feature of the mechanism shown is that the swivel shuttles are oscillated first in one direction and then in the opposite direction at one and the same pick of the loom, said swivel shuttles being oscillated in one direction to lay the swivel threads below the raised warp-threads as the lay swings back, and being operated to lay the swivel threads above said warp-threads, which warp-threads have in the meantime been lowered, during the return or forward beat of the lay.

In the construction in my co-pending application hereinbefore referred to, and in which it is necessary to employ a lost pick, in order to produce figures which will appear on both sides of the fabric, the swivel shuttles are oscillated in one direction at one pick of the loom and then, after a binding pick has been put in, there comes the lost pick referred to at which no warp-.

threads are raised and at which therefore no weaving is done, and during which lost pick the swivel shuttles are oscillated in the opposite direction to lay the swivel threads above the warp threads.

The mechanism for moving the rack-bar 51 in opposite directions to oscillate the swivel shuttles is as follows: Secured to the main shaft 6 is a crank-wheel 5:2 provided with a crank-pin A link or connecting rod 54 connects said crank-pin 53 with a lever 55 loosely pivoted on a stud 56 secured to the frame. Loosely pivoted on said stud 56 is another lever 57 which is connected to the lever 55 by a spring 58. The'lever 57 is provided with an offset 57, as shown in Fig. 7, and so that when said lever 55 is moved upward said ofiset 57 will be in the path of said lever 55, and so that the lever 57 will, by engagement of the lever 55 with said offset, be moved forward, that is, toward the front of the loom. Loosely mounted on the stud 56 are two

other levers

59 and 60 which are connected together by a spring 61. The lever 60 is likewise provided with an offset 60 overlying the lever 59, as shown in Fig. 6, the arrangement being such that as the lever 59 is moved downward the lever 60 will, by the engagement of the lever 59 with said offset 60, be moved forward, that is, toward the front of the loom. A link or connecting-rod 54 is connected at one end to the lever 59 and at the other end is pivotally connected to the connecting rod 54.

Pivotally mounted on a stud 62 is a T- shaped or three-arm lever 68. To the arm 64 of said lever 68 is pivoted a block 65, which block is perforated to receive a rod 66 preferably screw-threaded and provided with adjusting nuts 66 for adjusting the position of said rod with relation to the block 65. The rod 66 is provided with a hook 68 adapted to engage a pin 69 which projects from the lever 57 at or near the end thereof. To the rod 66 is connected a jacquard cord 67 which controls the engagement of the hook 68 with the pin 69, and thus controls the operation of the rack-bar 51, in one direction, as will be hereafter described. To the arm 70 of the lever 63 is pivoted a corresponding block 71, which is perforated to receive a rod 72, which said rod is likewise preferably screwthreaded and provided with adjusting nuts 73. The rod 72, instead of being provided with a hook, is provided with an elongated slot or loop, into which extends the pin 74 projecting from the lever 60 at or near the end thereof. The arm 64 of the lever 63 is extended upward above the block 65, and is 7 provided with a projecting pin 75, to which is connected one end of a spring 76, the other end of said spring being secured to the floor or to some fixed support.

To the end of the arm 77 of the T-shaped lever 63 is connected one end of a connecting rod 78, the other end of which rod is connected to the arm 79 of a bell-crank lever pivoted on a bracket 80 secured to the frame, and connected to the other arm 81 of said bell-crank lever is a connecting rod 82 which is connected at 83 with the rack-bar 51. Secured to the frame is a bracket 84, in the upper end of which is adjustably mounted a rod 85, the end of which rod is bent as at 86, so that such bent portion will lie in the path of the lever 57 and form a stop to limit the rearward movement of said lever. Adjustably mounted in the lower end of said bracket 84 is a corresponding rod 87, the end of which is bent as at 88,-so that such bent portion will lie in the path of the lever 60 and limit the rearward movement of said lever. Adjustably mounted in the upper end of said bracket 84 is another rod 85, the end of which rod is bent as at 86 so that such bent portion will lie in the path of the arm 64 of the T-lever 63 and form a stop to limit the movement of said lever in one direction under the action of the spring 76. Adjustably mounted in the lower end of said bracket 84 is another rod 87, the end of which is bent, as at 88, so that such bent portion will lie in the path of the arm 70 of the lever 63 and limit the movement of said lever in the opposite direction under the action of said spring.

The operation of the parts above described for oscillating the swivel shuttles to lay the swivel threads to weave figures which shall appear upon both sides of the fabric is as follows: By the revolution of the crankwheel 52 continued up and down movements are imparted to the

levers

55 and 59, and as the lever 55 moves downward, it will, by means of the connecting spring 58, pull the lever 57 rearward, and as said lever 55 moves upward it will, by its engagement with the offset 57 push said lever 57 forward. So also as the lever 59 moves upward, it will, by means of the connecting spring 61, pull the lever 60 rearward, and as said lever 59 moves downward it will, by its engagement with the ofiset 60 push said lever 60 forward. Thus by the revolution of the crank-wheel 52, continued forward and backward movements are imparted to the

levers

57 and 60, which movements will continue as long as the crank-wheel 52 is rotated, that is, during the operation of the loom. When now it is desired to operate the swivel shuttles the jacquard cord 67 is operated by the jacquard mechanism to raise the hook 68 into the path of the pin 69 on the lever 57. When the hook 68 has been engaged with said pin 69 the rearward movement of the lever 57 will operate to swing or turn the T-lever 63 by reason of the connection of the rod 66 with the arm 64: of said lever. The turning of said lever 63 will cause the arm 77 of said lever to be raised, which in turn will raise the connecting rod 7 8, and thereby swing the

bellcrank lever

79, 81, in a direction to pull the rack-bar 51 from right to left in Fig. 1. Such movement of the rack-bar will, by reason of the intermediate pinions 51 serve to oscillate the swivel shuttles 27 in the direction of the hands of a clock. It may be noted that after the T-shaped lever 63 has passed the center, the spring 76 will operate to quickly throw said lever 63 to its extreme position, and thus a rapid movement will be given to the swivel shuttles.

The stop 86 will serve to limit the rearward movement of the lever 57 under the pull of the spring 58, and if under the throw of the lever 63, there should be a further rearward movement of the hook 68 sufficient to clear said hook from the pin 69, said hook may then be dropped by the jacquard mechanism out of the path of said pin 69. It is preferred, however, to so time the jacquard mechanism that the dropping of the rod 66 and the hook 68 shall take place immediately after the nextforward movement of the lever 57 has commenced, and as soon as said lever has moved forward far enough to enable the hook 68 to disengage the pin 69. The stop 88 will likewise serve to limit the rearward movement of the arm 70 of the T-lever 63 under the action of the spring 76, and will thus serve to limit the movement imparted to the swivel shuttles, and so that said swivel shuttles will be brought to rest in the proper position.

As in the present construction the levers 57 and '60 are by the operation of the crankwheel 52 caused to move simultaneously in opposite directions, it will be seen that when the lever 57 is moved rearward to swing the T-lever 63 in one direction the lever 60 will be moved forward and will thus follow or remain substantially parallel with the lower end 7 0 of said Tlever, which lower end 70 will be moved forward as the upper end 64: is moved rearward by the lever 57. Thus when the T-lever 63 has been turned by the rearward movement of the lever 57, through the engagement of the hook 68 with the pin 69, to move the swivel-shuttles in one direction, the pin 7 at will still occupy the same position with relation to the rear end wall of the loop in the loop-member 72, as is shown in Fig. 2, and so as thus to be in engagement therewith, and so that when the lever 60 begins to move rearward, it will, by the engagement of the pin 74 with the end wall of the loop in said rod 72, pull on said rod, and thus operate to return the T-shaped lever '63 to its original position, which movement of said lever will cause a downward pull in the connecting rod 78, which will serve, through the intermediate connections, to move the rack-bar 51 in the opposite direction, that is, from left to right in Fig. 1, thereby oscillating the swivel shuttles in the return direction, that is, in a direction opposite to the hands of a clock. It will be noted that when the T-shaped lever passes the center on this return movement, the spring 76 will again act to complete the movementof said lever and thus impart a quick return movement to the swivel shuttles. The stop 86' serves to limit the movement of the arm 64 of the lever 63, upon this reverse move-. ment of said lever under the action of the spring 76, and thus serves to limit the extent of movement of the swivel shuttles in their return oscillation.

As above stated, the first oscillating movement of the swivel shuttles above described, that is,the movement in the direction of the hands of a clock, takes place during the backward movement of the lay and while the warps for the swivel figures are raised, and so that the warp-threads will be laid by the swivel shuttles beneath said raised warpthreads. The return oscillating movement of the swivel shuttles, however, takes place during the forward beat of the lay, and'the parts are preferably so arranged and timed that such return movement of the swivel shuttles will take place at about the time the lay has reached its forward position, and thus at a time when the swivel shuttles are substantially above the woven fabric, and also at a time when the swivel shuttle bar is in its raised position. It will be understood, therefore, that in this return oscillating movement of the swivel shuttles the swivel-threads will be laid above the warpthreads. I

If desired the

springs

58 and 61, which connect the

levers

55 and 57 and the

levers

59 and 60 respectively, may be omitted, and said levers may be rigidly connected together, so that the

levers

55 and 59 will operate the

levers

57 and 60 positively in both directions. It is preferred, however, to connect these levers by springs as shown and described and for the following'reasons:

It is desirable that the oscillating movement of the swivel shuttles shall be quickly performed, and for this purpose the spring 76 is employed to complete the throw of the T-shapecl lever 63 after said lever has passed the center. If the levers and 57, for eX- ample, were rigidly connected together, and said spring 7 6 be employed to operate in the manner described, the result would be that the hook 68 would be caused to travel rearward under the action ofv said spring 76 more rapidly than the pin 69 could follow under the positive action of the crankwlieel' 52. By employing the spring 58, however, to connect said levers and 57, said spring 58 will, by the initial downward movement of the lever 55, be put under tension and will be maintained under such tension during the initial movement of the T- shaped lever 63, and so that, when said lever 63 passes the center and the spring 76 comes into operation, the tension thus set up in the spring 58 will cause said spring to pull the lever 57 rearward faster than movement would be imparted thereto directly by the lever and so that thereby the pin 69 on said lever 57 will be kept in engagement with the hook 68 during the rearward movement of said hook. Thus with the construction described the operation of swinging the "I -shaped lever 63 to oscillate the swivel shuttles will be as follows: When the lever begins to descend, it will first set up a tension in the spring 58 and will then, tlirougl'i said spring, serve to pull the lever 57 rearward, which by the engagement of the pin 69 with the hook 68 will in turn serve to pull rearward the arm 64 of the T-shaped lever 63 until said lever has passed the center, whereupon the remaining rearward movement of said lever 63 will be effected by the spring 76, and in this latter movement the spring 58 will operate to keep the pin 69 in engagement with the hook 68. Thus means for giving a quick oscillating movement to the swivel shuttles is provided without the liability of the hook 68 being prematurely disengaged from the pin 69. Moreover with the employment of said spring 58' an easy action of the parts is secured and jar and shock to the mechanism is prevented. What has been said with re spect to the function and operation of the spring 58 likewise applies to the corresponding' spring 61.

Another important feature of the present invention is that the oscillating movements of' the swivel shuttles in opposite directions are both caused to take place at one and the same pick of the loom, the oscillating movement of the shuttles in one direction taking place during the backward movement of the lay, and the oscillating movement of said shuttles in the opposite direction taking place during the forward beat of the lay and at the same pick. By thus causing the oscillating movements of the swivel shuttles in both directions to take place at one and the same pick, only one jacquard cord re quires to be employed for controlling the oscillating movements of said shuttles in both directions. In other words, the connection bet-ween the power mechanism, viz., the crank-wheel 52 and the

levers

57 and 60, and the mechanism for moving the rack-bar 51, requires to be disengaged at only one point, and consequently there requires to be employed only one engaging and disengaging hook, via, the hook 68, and consequently only one jacquard cord is required to make and break such single connection between the power mechanism and the mechanism for operating the rack-bar. By thus having the return oscillating movement of the swivel shuttles take place upon the forward beat of the lay at the same pick, the connection between the lever 60 and the T-shaped lever 63 does not require to be disconnected at any time, but instead said lever 60 is always connected to the lever 63 by the looped bar 72. By this construction, when the hook 68 is engaged with the pin 69, the T-shaped lever 63 will be moved in one direction during one half of the rotation of the crank-wheel 52, and then during the remaining half revolution of said crank-wheel, said lever 63 will be iml'nediately swung in the opposite direction by the engagement of the pin 74 with the end of the looped bar 72, and so that the return oscillating movement of the swivel shuttles will thereby be caused to take place during the second half of the same revolution of the crank-wheel 52, and thus during the forward beat of the lay at the same pick, and this result will be acco1nplished without any control of the looped bar 72 by the jacquard mechanism, no such control of said looped bar being necessary.

As will be undestood, the

levers

57 and 60 are oscillated continuously by the crank wheel 52 and so that said levers oscillate, not only during the operation of the swivel shuttles, but also while the swivel shuttles are out of operation and plain weaving is being done. It will be further understood that while plain weaving is being done, the hook 68 is out of engagement with the pin 69 on the lever 57 while the pin 7 4 on the lever 60 plays back and forth in the elongated loop of the bar 72, and thus without imparting any movement to the T-lever 63.

There remains to be described the construction and operation of the mechanism for moving the swivel shuttle-bar longitudinally, that is, crosswise of the loom, for the purpose of locating the swivel figures upon the fabric.

Rigidly secured to the rod 33 at the left hand side of the loom, as shown in Fig. 1, is an arm 89, which stands substantially vertical, and which is provided with a groove 90 extending lengthwise thereof. Pivoted to the bracket 29 is a bell-crank lever 91, the arm 92 of which lever is provided with a friction-roll 98 which rides in the slot 90 of the arm 89. The arm 9 of said lever is connected by means of a connecting rod 95 with one end of a lever 96 pivoted to the frame. To the other end of said lever 96 is connected the jacquard cord 97. Preferably the arm 94 of the bell-crank lever 91 is provided with an elongated slot 98, whereby the connection of the rod 95 with said arm 94 may be adjusted to vary the throw imparted to the swivel shuttle bar. A spring 99 is connected at one end to the frame and at its other end to the opposite end of the lever 96 from that to which the jacquard .cord 97 is connected, the arrangement being such that the jacquard cord will move said lever 96 in one direction, and the spring 99 will move said lever in the opposite direction. Preferably there is adjustably secured to the rod 38 at the opposite side of the loom a stop 100 for limiting the movement of the swivel shuttle bar under the action of said spring 99.

The operation of the parts above described will be readily understood. \Vhen the swivel shuttle bar is to be shifted laterally in one direction to locate the swivel figures, the cord 97 is operated by the acquard mecha nism to actuate the lever 96, so as to pull downward the connecting rod 95, which will have the effect, through the bell-crank lever 91 engaging the arm 89, to move the swivel shuttle bar from left to right in Fig. 1. When it is desired to move the swivel shuttle bar in the opposite direction the operation of the jacquard mechanism will permit the spring 99 to operate the lever 96 to pull the connecting rod 95 upward, which will serve to move the swivel shuttle bar .in the opposite direction, that is, from right to left in Fig. 1, the movement of said bar in this direction being limited by the stop 100. It is preferred that the operation of the jacquard mechanism shall be such that the movement of the swivel shuttle bar under the action of the spring 99 will be a gradual rather than a sudden movement.
