SWIVEL-LOOM.

SPECIFICATION forming part of Letters Patent No. 471,665, dated March 29, 1892.

Application led November 19, 1890. Serial No. 371,926. (No model.)

To a/ZZ whom it may concern:

Beit known that I, JOHN C. BROOKS, a citizen of the United States, residing at Paterson, Passaic county, and State of New Jersey, have invented certain new and useful Improvements in S'vviveLLooms; and I do hereby declare the following to be a full, clear, and eX- act description of -the invention, such as will f enable others skilled in the art to which it ro appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specication.

The object of this invention is to furnisha double-swivel-shuttle mechanism in a loom adapted to simultaneously weave two colors in the figures of the fabric; also, reliable and simple means for raising and lowering the same, and also to provide means for alternately operating the swivel-shuttles in conjunction with the iy-shuttle.

The invention consists in the novel and peculiar arrangements of mechanism for operating two or more swivel-shuttles alternately in connection with the ily-shuttle mechanism, lneans for raising and lowering the swivelshuttle rack and controlling the operation of the fly-shuttle mechanism, and the combination and arrangement of the various parts, as will be hereinafter more fully described, and finally embodied in the claims.

Referring to the accompanying drawings, in in which like letters and numerals of reference indicate corresponding parts in each of the several views, Figure l is an end view of a loom embodying my improvement. Fig. 2 is a front view thereof, showing the various operating mechanism, the reed and reed-cap being omitted and the breast-beam partly broken 4o away. Figs. l and lb are detail views of a mechanism for controlling the swivel-shuttles. Figs. 3 and 4 are detail views of one of the cam-wheels controlling the movements of the picker-sticks and the swivel-shuttle-raising mechanism. Fig. 5 is a sectional view on line am of Fig. l. Fig. 6 is a detail perspective view showing a portion of the swivel-shuttle bar-elevating mechanism. Fig'. 7 is a detail front elevation of a portion of the swivelshuttle frame in which the swivel-shuttles work. Fig. 8 is a vertical section on the line 8 8 of Fig. 7, and Fig. 9 is a detail plan View of one of the swivel-shuttles.v

In said drawings, A represents the loomframe.

B B are thelay-swords; C, the lay on which is the shuttle-race, over which the iiy-shuttles arethrown by picker-sticks w.

' O' is the swivel-shuttle-supporting bar carrying the swivel-shuttle boxes ob',having par- 6o allel grooves ab, in which the swivel-shuttles 30 are operated by pinions 60 6l 62. These pinions are operated by sliding racks c c', connected by rods d d' with crank-arms e e', the arm e being rigidly secured to a hollow shuttle-driving rod D and the arm e' to the shuttle-driving rod D', which is arranged insideof the tubular driving-rod D.

F is the main driving-shaft, with crank-arm f rigidly secured thereto. This crank-arm f 7o is pivotally connected by a rod g with a vertical lever h, fulcrumed at h' to the frame A. Upon one end of the driving-shaft'are arranged fixed and loose pulleys 50 and 51 and also a fixed gear-Wheel 52, meshing into agear-wheel 53, secured on thecam-shaft 5. This shaft 5 extends across the machine and carries cams 4, as shown in Fig. 2.

To the lower end of lever h is secured, by means of a bolt 10, an arm e', provided with a 8o slot 11 for the purpose of changing the throw of the swivel-sh uttles. This arm is also provided at its free end with a pin z", which latter operates the hooked arms k lo', secured to crossarms k2 k3, attached to swivel-shuttle- 85 driving rods D and D', respectively, as shown in Figs. l and 5, and adapted to oscillate said driving-rods in their bearings E E', the upper one being secured to lay C and the lower one being supported on the lay rock-shaft t. To 9o the lever h is also pivoted a rod m, connecting said lever with an arm n, pivoted on shaft H and carrying a pawl n', whereby cam-shaft H is rotated intermittingly by means of the ratchet-Wheel n2, as shown in Fig. l. On this cam-shaft H is secured a side cam-wheel R, having four cam depressions R', as shown in Figs. 3 and fi. In contact with said cam is a pin o, secured to the rear end of aflever 19 ivoted at to a bracket A on the frameA los p 29 and adapted to oscillate said lever p on its pivot, the other end of this lever p being proscribed is arranged at the other side of the loom, as shown in Fig. 2.

rPhe picker-stick wis operated through a leather-strap connection w by a crank-arm 1, rigidly secured to a rock-shaft 2. On this shaft 2 is secured a pin, on which revolves a small Wheel 3, resting on the outer periphery of cam .ton shaft 5, as shown in Figs. 1 and 2. The lower end of the picker-stick w is connected by a leather strap 12,having an int-ermediate spiral spring,with the corresponding picker-stick on the other end of the machine. The return motion of the picker-sticks is caused by the said spring. The elevations of the cams R hold the picker-sticks out in their normal position, and when the cams are rotated, so that the pins 0 rest in the depressions in the said cams, the springs to2 slide the levers s (on which the picker-sticks are mounted) inward, from which it will be apparent that this shifting of the fulcrum of the picker-stick slackens the connection w', so

- that the tiy-shuttle is not picked at the time the swivel-shuttles are thrown. The lay (l receives its oscillating movement from the main driving-shaft F, through crank- connections 22 and 23, one of which is shown in Fig. 1.

Upon the lay rock shaft t are arranged two rocker-arms 6, one of which is shown in detail in Fig. 6. These rocker-arms have an opening 7, through whichv passes a vertical rod 8, attached to the swivel-shuttle bar C', which is held in its normal raised position by springs 9. The lower ends of these rods 8 8 are connected by a cross-bar 10, having in its center a cam 11, Fig. 2, upon which slides or moves a small wheel 13, rotating upon a pin secured to lever 14 andadapted to be adj usted in aslot 15 in said lever. pivoted at its upper end to the cross-brace B2 of the lay-swords B B, and its lower end is connected by a connecting-rod 16 to pin r of the lever s at the left-hand side of the loom and operated by the reciprocating motion of said lever produced through oscillating motion ofleverp, operated by cam-wheel R. By this connection the lever 14 receives an oscillating motion and presses (when rod 16 is moved to the right) the cross-bar 10 downward by the roller 13 riding on the cam, and by this movement causes the swivel-shuttle bar C to be lowered, and by the action of the springs 9 9 (when rod 16 is moved to the left) -to be raised.

Upon the rear portion of the machine is arranged a shaft or stud P, on which is a cam- This lever 14 is cylinder Q, having on its outer periphery four grooves Q', in which rest alternatelyone end of lever-arms 17, the other end of said arms being loosely pivoted to a shaft or stud 18 on frame A. The periphery of the said cam-cylinder is divided into six equal spaces, in the first, second, fourth, and fifth of which are the grooves Q', while the third and sixth of such spaces are not grooved. The free ends of said levers are connected by cords or wires 19 with the hooked end levers k 7c. one of the levers 17 dropsin one of the grooves Q of cam Y- cylinder Q', the corresponding hooked endlever lc or 7c" engages with pin t When f ing-rod D or D'.

The pattern-drum Q receives its motion from the main driving-shaft F through a pawl 2O and ratchet 21, as shown in Figs. 1 and 1a. This pawl 20 is connected by a wire 40 with the Jacquard mechanism. (Not shown in the drawings.) On the front of the drum Q is rigidly secured thereto a cam-wheel 25, provided on its outer periphery with four depressions 28, arranged to correspond with the four grooves Q of cam-cylinder Q, and also provided with two .cam projections 28, arranged opposite each other and adapted to raise a lever 26 by means of a small wheel 27, pivoted to the said lever, which latter is pivotally secured to shaft 18, and is connected at its free end by cord 35 with the pawl fn. on lever n. The said cam-wheel 25 being also divided into six equal spaces, its four depressions 28 register with the four grooves of the cylinder Q and its two cam projections correspond with the two ungrooved portions Vof the said cylinder. When the lever 26 rests IOO IIO

tern-drum Q is prevented from being turned more than one-sixth of a revolution; but whenever the said pattern-drum has made onehalf revolution (and none of the levers 17 rest in their respective grooves) thelever 26, with its Wheel 27, is raised by the projection 28n of wheel 25, and thereby and by its cord connection 35 raises the pawl fn. and prevents the cam-wheel R from being further rotated.

As will be seen from Fig. 7 of the drawings, the swivel-shuttles are arranged in the shuttie-boxes one above the other, and are respectively operated by the rods D and D, these two rods being operated from the main driv-` ing-shaft by means of the hooked levers controlled by the pattern-drum Q.

With my improvcd-doubleswivel shuttleloom two different -movements may be effected-the plain or iiy shuttle movement and the swivel and plain-weaving movement com-V bined.

ing, the pawl 20, pivoted to rod h, is raised f on its pivot (through its wire connection) by the Jacquard mechanism, so that the patterndrum Q is not revolved by the said pawl. As the main driving-shaft F revolves the crank connections f g cause the rod h to reciprocate, and thereby transmit its motion through connections mn and pawl n to cam-carrying shaft H. The cam-Wheel R, which is firmly secured to the said shaft H, causes the lever pto oscillate on the pivots p', and to reciprocate the levers s, to each of which a picker-stick w -is pivotally secured. When the levers s are moved outward on rocker-shaft t by levers p and cams R, the upper end of the pickersticks w, which latter are pivoted at 'u to the said levers, is thrown inward by the action of cams 4 4 on shaft 5 and the connections w. Thereby the fly-shuttle is thrown across the loom, as in ordinary weaving. The camwheels 4 4 on shaft 5 are so arranged that they will operate first the picker-stick on one side and then the picker-stick on the other side, and so on. By these movements the body of the fabrics is produced. I will now proceed to describe the operation whereby by the action of the swivel-shuttles the figures or patterns are woven in the fabric. For this purpose the pawl 2O is lowered by the Jacquard and brought in contact with ratchet-wheel 21, causing the pattern-drum Q to revolve.

The horizontal movement of the swivelshuttles is produced` through connection Z CZ and ce', whereby the arms e e are alternately oscillated with their respective rods D and D', the latter receiving their motion fromthe main driving-shaft F through connections f, g, h, and z', pin t", and hooked end levers k la', pivotally secured to cross-arms 102763, firmly secured to their respective rods D and D. As already specified, the said levers k 7a are connected by wires 19 to one end of levers 17, pivoted at 1S, and operated by the movement of drum Q, only one of said levers 17 resting at one time in one of the four grooves Q in said drum. The other three are resting on the outer periphery of said drum, thereby raising the hooked end levers and bringing the latter out of contact with oscillating pin 'i'.

The up-and-down movement of the swivelrack C is produced by the oscillating motion of lever 14 depressing the connecting-bar 10,

(by passing over the cam 11 arranged thereon,) and by the spiral springs 9 9, (which are compressed by this down motion.) This lowering and raising device is so arranged that almost simultaneously with the downward movement of the swivel-bar C the swivelshuttles are driven alternately longitudinally across the loom, the lower one from right to left and the upper one from left to right, or vice versa, thereby weaving the figure or pattern in the fabric. V During one revolution of -cam-wheel R the swivel-shuttles are lowered four times, and each of said swivel-shuttles is thrown twice across the loom. By one revolution of the cam-shaft 5 the iiy-shuttle lis thrown twice across the loom.

The co-operations of the fly and swivel shuttles are as follows, reference being had to Fig. 2: The right -hand picker stick w throws the iiyshuttle from right to 'left through the shuttle-race, making plain weaving. The swivel-shuttles are now lowered and are moved alternately in opposite directions and weave part of the figure and are then raised. Then the left-hand picker-stick throws the iy-shuttle through the race from left to right, making plain weaving. The two swivel-shuttles are now again lowered and moved alternately in opposite directlons and weave part of the figure and are then again raised. This'operation is repeated until the loom is changed or adjusted for plain weaving by raising the pawl 20, as heretofore described.

The cooperative movements of ly and swivel shuttles are controlled by patterndrum Q, wheel 25, and their respective levers, as follows: When the pattern-drum` Q has been turned one-sixth of its revolution and all the levers 17 are resting on the outer periphery of drum Q, (none in their respective grooves,) the cam projection 28n of wheel 25 raises the lever 26, with its wheel 27,`and thereby (by cord connection the pawl fn', thus preventing the further rotation of camwheel R. This is the movementin which the iy-shuttle is thrown through the race. With the next move of drum Q (one-sixth of its revolution) one of the levers 17 engages its corresponding groove, thereby allowing its respective hooked end lever to be 'engaged and operated by the oscillating pin The lever 26, with its wheel 27, rests in one of the depressions 2S of wheel 25. This is the moment the swivel-shuttle makes one pick.V

The next move of drum Q (one-sixth of its revolution) produces a similar result. (Second pick.) Vith the next move of the pattern-drum the lever 26 is again raised by the second cam projection 28a of wheel 25, the pawl n is disengaged from its ratchet, and the cam-wheel R is stopped in its rotation. During thattime the fly-shuttle is thrown back through the race. The next two moves necessary to complete one revolution of the pattern-drum produce the third and fourth picks in amanner similar as heretofore d'escribed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
