sra'rns PATENT OFFIC FREDERICK I. ROCHE, OF LINCOLN, RHODE ISLAND, ASSIGNOR TO MANVILLE COMPANY, OF PROVIDENCE, RHODE ISLAND, A CORPORATION NEW JERSEY.

SWIVEL-LO OM.

To all whom it may concern Be it known that I, FREDERICK F. ROCHE, of Lincoln, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Swivel-Looms, (Case A;) 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 the weaving of swivel figures the following main operations are required, viz., the main or fiy shuttle must be thrown out of operation; the swivel shuttles must be put into and out of operative position; the swivel shuttles must be oscillated to lay the swivel threads; and the swivel shuttles must be moved transversely of the loom to locate the swivel figures.

One object of the present invention is to provide simple and efficient mechanism whereby these several operations may be automatically controlled by a suitable pat-ternmechanism, preferably a jacquard mechanism.

Another object of the invention is to provide means whereby the swivel figures may be caused to appear either on one side only of the fabric, or on both sides of the fabric, as may be desired.

Another object of the invention is to provide means whereby the oscillating movements of the swivel shuttles may be quickly effected in either direction, and said shuttles be brought after each oscillation to the proper position for their next operation.

The invention consists in certain combinations and arrangements of parts whereby these several objects, among others, are accomplished as hereinafter described and claimed.

Referring to the drawings, Figure 1 is a front elevation of a loom provided with my improved swivel shuttle mechanism, the parts of the mechanism and of the loomframe 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 mechanism is located. Figs. 3 to 6 inclusive are details of different parts of the mechanism.

In the accompanying drawings, 1 repre- Specification of Letters Patent. Patented Fgb 17 9 1914 Application filed. September 28, 1907. Serial No. 394,995.

sents the loom-frame, 2 the lay, 3 the layswords, 4 the hand-rail, 5 the main or flyshuttle box, 6 the main or crankshaft, and 7 the cam-shaft of the loom, all of the above parts being of the usual-or any desired construction.

When the swivel figures are to be woven in the fabric, it is necessary to prevent the operation ofthe 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 picking-rolls on the camshaft, and so as to move said picking-rolls 1nto and out of engagement with the picking-shoes on the picker-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 the 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 shipperrods 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 picking-rolls out of line with the picking-shoes by means of the spring 12, one end of which spring is connected to one of said shipperrods, the other end of said spring being connected to the other shipper-rod. Pivoted on the stud 18 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, it will be understood, leads to a jacquard mechanism, not shown. The other arm 18 of said lever is connected by means of a link 19 to one arm 20 of a bellcrank 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 bell-crank lever 15 and, through the connecting rod 19, to turn the bell-

crank lever

20, 23, and so as to thereby move the shipper-rod 1O lengthwise against the action of the spring 12.

The swivel shuttle-bar 2G, in which the swivel shuttles 27 and the rack and. pinions 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, a movement 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 guide-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 it by moving the vertically sliding blocks 31 in 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 theguide-rod 34 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 37. The mechanism for giving the necessary up and down movements to said rods 3'? and for determining the times when such movements are to take place are as follows:

Secured to the frame at each side of the loom is a cam 38, and to each of the rods 37 is secured a friction-roll 39 adapt-ed to engage said cam 38. The construction and location of the cams 38 are such that, as long as the rods 37 are free to move up and down, said rods 37 and the swivel shuttle-bars supported thereby will be moved up and down at each forward and back motion of the lay by the riding of the rolls 39 up and down the cams 38. As will be seen, the swivel shuttle-bar will be raised to its upper or inoperative 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.

lVhen 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 shuttie-bar in its upper position is not only controlled, but is effected, by the jacquard cord 17, which cord also controls 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 at 42 to a bracket 43 secured to the frame. Pivotally connected to the arm 44 of said bell-crank lever is a link or connecting rod 45, which said link is in turn pivotally connected to the end of an arm 46 projecting from a rockshaft 47. Said rockshaft 47 extends across the loom and is provided at each end with a projecting arm 48. The lower ends of the vertically moving rods 37 are pivotally connected one to the end of each of said arms 48. The lower end of the link or connecting-rod 45 is provided with an elongated slot 49, in which slot the connecting pin 50 which connects the arm 46 to said link 45 may play. With this construction, it will be seen, 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 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 posit-ion, and so as to thereby hold the rolls 39 on said rods 37 entirely above and out of engagement with the cams 38, the swivel 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, thereby operating the main shuttle. So also during plain weaving the swivel shuttle-bar 26 will be held in its upper or inoperative position, said pickingrolls and said swivel shuttle-bar being held in such positions by the jacquard cord 17 and the intermediate connections above described against the action of the spring 12 which is under tension at this time. When 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 released to operate, the operation of which spring serves to move the shipper-rods l0 and 11 in opposite directions, and so as to move the picking-rolls 8 at opposite sides 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 bellcrank 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 permit-ted 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 I bar thus permitted is to be sufiicient to bring ments 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 slots permit the up and down movement 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 S in line with the picking-shoes 9, and so that the main or fiy-shuttle will again be 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 bar 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 opera-ted, 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 and which said pinions in turn engage horseshoegears 52 connected with the swivel shuttles.

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 52 provided with two crank-

pins

53 and 54 arranged 180 apart. In the construction shown in the drawings the crank-pin 54 is mounted on the crank-wheel 52 in the following manner: Rigidly secured to the crank-pin 53 is an arm 55 provided with a slot 56, in which slot the crank-pin 54 is adjustably secured. A connecting-rod 57 connects the crank-pin 53 with one arm of a bell-crank lever 58 which is loosely pivoted on a stud 59 secured to the frame. A connecting rod 60 connects the crank-pin 54 with one arm of a second bellcrank lever 61 likewise loosely pivoted on the stud 59. It will be understood that the arm 55 which carries the crank-pin 54 is offset on the crank-pin 53 with relation to the connecting-rod 57, and so that as the crankwheel 52 is rotated said connecting-rod 57 will pass between said arm 55 and the wheel 52.

Pivotally mounted on a stud 62 is a T- shaped or three-armed lever 63. To the arm 64 of said lever 63 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 arm 70 of the bell-crank lever 58. 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. 64 of the lever 63 is pivoted a corresponding block 65 which is perforated to receive a rod 71, which said rod is likewise preferably screw threaded and provided with adjusting nuts 72. The rod 71 is provided with a hook 73 adapted to engage a pin 74 projecting from the arm 75 of the bell-crank lever 61. To the rod 71 is connected a jacquard cord 67% which controls the engagement of the hook 73 with the pin 7-1, and thus controls the operation of the rack-bar 51 in the opposite direction, as will be hereafter described.

The arm (i l of the lever 63 is extended upward above the block 65 and is provided with a projecting pin 64c" to which is con nected one end of a. spring 7 6, the other end of said spring being secured to the floor or to some other fixed support. To the end of the arm 7 7 of the T-shaped lever 63 is con nected one end of a connecting rod 78, the other end of which rod is connected to the arm 79 of a bellcrank lever pivoted ona bracket 80 secured to the frame, and connected to the other arm Ell of said bell-crank lever is a connecting rod 82 which is connected at 83 with the rack 51.

Secured to the frame is a bracket Set in the upper end of which is adjustably mounted a rod S5,the end of which rod is bent as at 86, so that such bent portion will lie in the path of the arm 6stof the 'l -lever (33, 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 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 arm 6s 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 on one side of the fabric only is as follows: By the revolution of the crankwheel 52 the bell-crank levers and 61 are continuously oscillated so that the arms and 7 5 of said levers respectively move simultaneously in the same direction, that is, both of said arms move rearward at the same time and both of said arms move forward at the same time. When new it is desired to operate the swivel shuttles the jacquard cord 67 is operated by the jacquard mechanism raise the hook 68 into the path of the pin 69 on the arm 70 of the bellcrank lever vi hen the hook 68 has been engaged with said pin 69 the rearward movement of the arm 70 will operate to swing or turn the T-lever 63 by reason of the connection of the rod (36 with the arm 6st 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 78 and thereby swing the bell-crank lever 79, 81., in a direction to pull the rackbar 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 menace 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 shuttle. The stop 88 will serve to limit the rearward movement of the arm 6-1 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 proper position. it is preferred to so adjust the stop 88 as to permit the hook 68 to move rearward somewhat farther than the pin 69 is carried by the rearward movement of the arm 70, and so that said hook (38 may thus be readily disengaged from the pin 69 by the operation of the jacquard mechanism.

The parts are so timed that the oscillation of the swivel shuttles by the mechanism above described takes place during the backward swing of the lay, and thus at a time when the swivel shuttle bar is lowered into operative position by the rolls 39 riding down the cams 38, and so that said oscillating movement of the swivel shuttles will serve to lay the swivel threads beneath the warp-threads which have been raised for the formation of the swivel figure. As will be understood, the oscillating movement of the swivel shuttles to thus lay the swivel threads beneath the raised warp-threads is effected during a half revolution of the crank-wheel 52. During the remaining half revolution of the crank-wheel 52, and thus during the forward beat of the lay, the swivel shuttles remain in their new position, and during such remaining half revolution both arms 70 and 7 5 of the bell-crank

levers

58 and 61 respectively move forward, that is, toward the front of the loom, whereby the pin 74: on the arm 75 will be brought to a position where it can be engaged by the hook 73.

lt is preferred to put in a binding pick after each operation of the swivel shuttles, and in such case the engagement of the hook 73 with the pin 7st will not be made immediately, but instead there will be one complete revolution of the crank-wheel 52 for the purpose of putting in such binding pick, at the end of which revolution, however, the pin 7% will again be brought to its forward position and where it can be engaged by the hook 7 3. The jacquard cord 67 is now operated by the jacquard mechanism to cause the engagement of the hook 7 3 with the pin 74, whereby at the next half revolution of the crank-wheel 52 the T-lever 63 will be turned in the opposite direction, thereby moving the arm 7 7 downward and through the intermediate connections oscillating the swivel shuttles in the opposite direction, and so as to return said shuttles to their original position. This return movement of the swivel shuttles will likewise take place during the backward swing of the lay, and so that the swivel threads will as before be laid beneath the raised warp-threads. Thus the swivel threads will during the movement of the swivel shuttles in both directions be laid beneath the raised warpthreads, and so that all the swivel threads will appear on the under side of the fabric as it lies in the loom, and so that the swivel figures will appear only on that side of the fabric. During the remaining half revolution of the crankwheel and thus during the forward beat of the lay the swivel shuttles will again remain inactive. The stop 86 serves to limit the movement of the arm 64 of the lever 63 upon this reverse movement 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. hen the swivel shuttles have thus been operated the hook 73 is disengaged from the pin 74: by the jacquard cord 67. A binding pick is then put in and the above operations are then repeated under the control of the jacquard mechanism as many times as are required to produce the desired swivel figure, when the operation of the swivel shuttles is discontinued'and plain weaving resumed.

It is possible with the mechanism above described to also produce swivel figures which shall appear on both sides of the fabric. In order, however, to thus produce swivel figures which shall appear on both sides of the fabric with the construction shown it is necessary that there shall be what may be termed a lost pick of the loom, that is, a pick at which no weaving is done, and for the reason that with said construction the arms 70 and 7 5 of the bellcrank levers 58 and 61 respectively move simultaneously in the same direction, and so that the rearward movement of both of the pins 69 and 74 takes place at the same time and during that half revolution of the crank-wheel 52 at which the lay swings backward. In other words, with the construction shown the swivel shuttles can be oscillated only during the backward swing of the lay. As during the backward swing of the lay the swivel shuttle-bar is by the cams 38 allowed to move to its lower position, it would be impractical to oscillate the swivel shuttles in such lower position, if at the time any of the warp-threads were raised, and at the same time lay the swivel threads above such raised warp-threads. It is desirable, therefore, that when the swivel threads are to be laid above the warp-threads none of said warpthreads shall be raised, and therefore the loom is caused to make a pick at which no weaving is done, and which may, therefore, be called a lost pick, for the purpose of enabling the swivel shuttles to be oscillated in the return direction to lay the'swivel threads above the warp-threads while said warpthreads are in their lower position.

When swivel figures are to be produced which shall appear on both sides of the fabric, therefore, the cycle of operations is as follows: WVhen the swivel figure is to be commenced the jacquard cord 67 is operated to engage the hook 68 with the pin 69 on the bell-crank lever 58, and so that at the first half revolution of the crank-wheel 52, and during the backward swing of the lay, the swivel shuttles will be oscillated in one direction by the action of the bell-crank lever 58 to lay the swivel threads beneath the warp-threads which have been raised for the purpose. During the remaining half revolution of said crank-wheel, and during the forward beat of the lay, the swivel shuttles will remain inactive. Then the binding pick is put in. Then comes the lost pick referred to, at which no warp-threads are raised and at which, therefore, no weaving can be done, and for this pick the jacquard cord 67 is operated to engage the hook 7 3 with the pin 74 on the bell-crank lever 61, and then during the first half revolution of the crankwheel 52 the swivel shuttles will be oscillated in the opposite direction under the action of said bell-crank lever 61 and returned to their original position, and thus return movement of the swivel'shuttles will, by reason of the fact that none of the warp-threads are raised, serve to lay the swivel threads above the warp-threads which enter into the swivel figures. Then another binding pick is put in, and the operations above described are repeated the required number of times to complete the swivel figures. As will be seen, by thus employing a lost pick, at which the return movement is imparted to the swivel shuttles, the swivel threads may be laid alternately below and above the warpthreads, andso that the swivel figures will thus appear on both sides of the fabric.

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 bellcrank lever 91, the arm 92 of which lever is provided with a friction-roll 93 which rides on the slot-90 of the arm 89. The arm 94 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 at 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 adapted 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 acquard cord w1ll 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 rec 33 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. When the swivel shuttle bar is to be shifted laterally in one direction to locate the swivel figures, the cord 97 is operated by the jacquard mechanism 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 99, 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. l, 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.

The construction and organization of parts above described constitutes a simple and eflicient mechanism for the production of swivel figures, the operations of which mechanism may be automatically controlled by a suitable pattern device. Moreover the construction is such that swivel figures which appear on both sides of the fabric, or figures which appear on one side of the fabric only, may be produced.
