SPECIFXCATION forming part of Letters Patent No. 650,165, dated May 22, 1900. Application iiled June 30, 1898. Serial Nu. 684,778. (No model.)

To if/ZZ whom it may concern:

Be it known that I, WILLIAM BRIMFIELD, a citizen of t-he United States, and a resident of Blue Anchor, Camden county, New Jersey, have invented certain new and useful Improvements in Looms, of which the following is a specication.

My invention relates to an improvement in figuring-machines for the production of textile fabrics; and the object of my invention is to furnish a machine for'the production of pile fabrics which will, in connection with a loom, produce such a fabric with the use of less yarn than is possible with the machines heretofore in use, which will produce the fabric direct from the yarn without first Weaving the yarn in a chenille-loom, which will automatically and exactly reproduce any desired pattern to which the machine may be set, and which will produce a fabric at the same time of better appearance, cheaper, and 0f better quality than is possible with the mechanism heretofore in use for such purposes. i

. In the accompanying drawings, forming part of this specification, and in Which similar letters and figures of reference indicate similar parts throughout the several views, Figure l is a side elevation of the upper part of a loom-frame furnished With my figuring device; Fig. 2, a side elevation of the lower part of the loom-frame, showing the carnshaft, the cams which operate parts of the working mechanism, the levers intermediate between the cams and the iiguring mechanism, dac.; Fig. 3, a perspective view of part of one side of the front of the loom-frame and of the figuring mechanism; Fig. 4., a front ele vation of part of the figuring mechanism; Fig. 5, a side elevation, partly in section, of the figuring mechanism, the stops or pushers being out of contact therewith; Fig. 6, a similar View, the pushers being in gear with the yarn-tube carriers; Fig. 7, a perspective view of mechanism for opening and closing the nippers; Fig. 8, a perspective view of one end of the stop or pusher carrying slats, showing one of the adjustable pushers in position; Figs. 9 and10,perspective views of `different forms of adjustable stops or pushers. Fig. 1l is a perspective view of one of the yarn-tube carriers.

' a is the main frame of a loom of any ordinary construction; b, Fig. 2, a cam-shaft, which may be driven in any convenient manner.

c d are the Warp-threads of the fabiic,\vhich are operated by the mechanism of the loom (not shown) in the usual manner.

e represents yarn-tube carriers, which are carried in a guide f. (Best shown in Figs. 3 and 4.) The guide f is furnished with parallel grooves, as shown, to receive andguide the carriers in their forward and backward movements, and the carriers, each of which can move independently of the others, are placed side by side and extend across the whole front of the machine. ber of yarn-tubes g, in the present instance seven, which number may be increased or diminished, as desired. The yarn-tube carriers are preferably constructed of metal. The set carried by each carrier are placed one directly back of the other and longitudinally of 'the loom, and the corresponding tube of each set of tubes forms a straight line transverse of the loom when in normal position. The tubes of each transverse row of tubes carry, ordina'` rily,the same color ofyarn, and for purposes of this description they will be so described, and the tubes of each longitudinal row carry yarn of different colors.

j is a pulley or cylinder carried on a shaft la, carried in suitable bearings in a movable frame o, around each end of which passes a belt, preferably an endless belt l, Fig. 1.

fm, Figs. l, 4, 5, and ll, represents slats carried by belts Z; n, stops carried by slats m, the size and position of which determine the movement of the several yarn-tube carriers and the pattern to be formed in the fabric.

The frame o, which carries the shaft k of the pulleys or cylinder j, is carried by the frame a of the loom and preferably upon rolln` ers p, Figs. 2 and 3, in orderto overcome friction as much as possible. The frame o, the cylinder j, and the chains Z and connected parts are moved back and forth as follows:

r is a bell-crank leverpivoted to the frame a at s. The lower arm of this lever is attached to one end .of a rod t, the other end of which is attached to one end of a lever uhFig. 2, which is pivoted at 'v and which is furnished with a friction-roller fw, which is en- Each carrier carries a num- ICO vIO

gagedy by a cam m, carried by cam-shaft bf The u-pper arm of bell-crank r, Fig. 1, is connected in any suitable manner with the frame o. As shaft b is revolved the outer end of lever u is raised and lowered by cam The raising of lever u causes frame o and connected partsfto'be moved outward. The lowering of this lever causes the frame and con-V nected parts to be moved inward.

Upon the shaft k is a ratchet-Wheel 1, and carried by the frame a is a pawl 2. When the frame o ismoved ou-tward,the pawl 2 en-f; gages one of the teeth of ratchetl, andwhen` this frame is moved inward this pawl draws lthe ratchet around one space, turning cylinder j, bringing one of the slats m int-o operative positioniin frontof this cylinder. Supf:

-pose' oneof lthe slats to be in operative position in front of the cylinder and frame o to be move'd forward.. As this takes place the' several stops fn, carried by Slat fm, will en gage each an end of a yarn-tube carrierie, and the several carriers thus engaged will be pushed forward, as best shown in Fig. 6. The remaining carriers that have not been engaged will remain in their normal position-'that shown in Fig. 5. The distance that the carriers are moved depends upon the position of stops fn.

onslat fm. If they be at the forward edge of. this slat, they will be moved to their greatestiforward position, if at the rear to their least forward position, and an intermediate position will cause them to be correspondingly'moved. As the yarn-tube carriers are -moved forward the yarn-tubes are moved with them, and Vthe distance that the carriers are moved determines which of the several tubes carried by themw will bebrought tothe workguide 6 is Yfurnished with `a notch 8 and the arm .7 with 4a downwardly-projectingfinger or lug 9. (Best shown in Figs. and 6.) The frame'io having been moved forward and the stops n having engaged and pushed forward the' severalV yarn-tube carriers until'the desired tubes are in line with notch 8 and lug 9, a cam'10`, carried .on cam-shaft b, Fig..2, causes'a lever 11, Fig. 2, to fall. The outer end `of 4lever 11 is connected to one end of a rod 12,Figs'. 1, 2,3, and 4, the outer end of which is *connected to a movable frame 13, which Vis carried by and vertically movable upon rods `or'guides 14, carried by the main frameof the loom. `As the lever 11 falls the r frame' 13 andthe parts carried by this frame fallwith it, and a lever 15, Figs. 3V and 4, which-is'pivote'd on the frame 13, is lowered. V16.is a rsp ring,`on e end of which isat'tached.

frame .13. Y Y

64 is an adjustable stop carried by loomframe a, which is adapted to bear against the upper outer end of lever 15, depressing the .outerendof this lever when the frame is in its raised position and raisingits inner end, as shown best in Fig. 4. When the frame 13 falls, the lever 15 falls with it, and immediately the spring 16 commences to draw down `the inner end of the lever which carries a pin 17, which engages an arm or link 2l, attached to a rod 22, which extends completely across thefront of the machine, and the lower end of which is sharpened, as best shown in Figs. 5 and 6. The sharpened end oredge of this blade engages one of the teeth orfnotches 23, formedon the'top of each of the tube-.carriers e and brings the rowof yarn-tubes into perfect alinement. The teeth or notches 23 correspond in number with the number of yarntubes-carried by each carrier e, andthe distance of one tooth from the next corresponds exactly to the distance from the center of one yarn-tube to the center of the next adjacent one. In other words, the pitch of the teeth 23 is equal to the pitch of the yarn-tubes. Both sides of the loom are furnished with the parts above described. A further downward movement of frame 13 causes pin 17 to engagethe to the inner side'ot lever 15 and the other to bottom of slot 18 in a connecting-rod 19, the

down rod 19, which pushes down'rod 20, which.

vcarries arm 7, VVand the lug 9 on this arm en- :gages projection 4 on the yarnftube'which is `in line with it, and the lng or projection 5 on the top of this particular tube entering notch 8 the yarn-tube is lowered, as shown in Fig. .6. A`The frame 13 having reached the endofits gdownward stroke the nippers 29, Figs. 1 and 2, of which there is one for each yarn-tube, are raised, passing between the Warp-threads, opened, and engaged with the threads passing downward out of the tubes. Theframe 13 is nowraised a distance equal to the length of pile required and stops,.Which movements are given by the shape of the cam 10. When the frame 13 stops, a cam 30 on the cam-shaft b, through a' lever 3l, draws arm 25` inward, and the upper end of this arm engages and Ymoves in a slide 32, which carries aroller 33, which engages aA bell-crank lever 34, which through a link 35 is connected to a slide `36, which carries one blade 37 of a shearsthe other blade 3S of which is carried bythe slide 32. The operation of -slides 32 36 causes .the

shears to cut oi the threads passing down-A 'ward through the tubes vand held by the vnippers. As soon as these threads are cut the cam 10 and connected parts raise the frame 13 and :connected parts to their highest position and the several parts take position, as at first described. While the frame 13 is rising ythe nippers 29 are being lowered and draw IOO IIO

down through the warp-threads the cut yarn that they are "holding, and when this yarn has been drawn down such a distance that its ends will project equally on each side of the warpthreads it is released by the nippers, a shot of lling is thrown in behind it by the loom, and the reed 39, which is actuated in any convenient manner, beats it up as usual.

The mechanism for operating the nippers is as follows: 40, Figs. 2 and 7, is an arm upon.

which one jaw of the nippers is carried. This arm is pivoted to one end of a link 41, which is pivoted a-t 42 to a bracket 43. Each side of the machine is similarly equipped. 44 is a pivot carried by arm 40. 45 is a lever depending from pivot 44, to the lower end of which is pivoted a link 46, the other end of which is pivoted to the upper end ot' an arm 65, the lower end of which is pivoted to frame a at 47. The arm 46 is operated bya cam 48 on cam-shaft b, which operates to throw arm 46 in and out, the outward movement operating to push rod 46 forward and to raise lever 45, arm 40, and the nippers` and the inward movement to lower these parts.

The nippers are opened and closed as fol* lows: 49 is a crank fast to pivot 44. 50 is a link pivotcd to the end of crank 40 and to a rod 5l, which is connected to the movable jaw 52 of the nippers. 53 is an arm attached to pivot 44. 54 is a rod, one end of which is at tached to the lower end of arm 53 and the other bar 58, which slides upon guides 59. After the yarn has been drawn out of Vthe tubes g and cut off, as described, and after the frame 13 has been again raised to its original position the frame o is moved backward, and projections 60, Fig. 1, on this frame engage the ends of bar 58 and draw it back and with it carriers e, that have been moved forward. The carriers c are thus returned to their first position. Upon the backward movement of frame o pawl 2 engages one of the teeth of ratchet'l, turning shaft and cylinder j and bringing a new slat m and its stops n into operative position in front of the cylinder.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a figuring mechanism for looms, in combination, a connected series of slats, a series of stops mounted on each slat, each stop being adjustable laterally on its slat and having an operative portion projecting from the face thereof, and means for bringing the stops of successive slats into position to adjust the yarn-carrying devices.

2. In a figuring mechanism for looms, the combination with a series of sets of yarn-carrying tubes, and a movable holder for each set, of a movable series of slats arranged transversely of the loom, a series of stops connected to each slat and adjustable laterally thereof, said stops having projecting portions end to the upper end of a lever 55,which is pivoted at 47 to frame d. 56 isa cam which is cal'- ried on shaft b and which operates to throw lever 55 in and out. When earn 56 throws lever 55 out, the jaws of the nippers are closed. When the lever 55 is moved in, rod 54 pushes arm 53 forward,rocks pivot 44, and causes crank 49 and link 50 to assume a position in line with one another. This pushes out rod 51 and opens the jaws of the nippers.

The several shafts on cam b are so shaped and placed that the several movements dictated by them will take place at the proper time.

The pattern to be formed in the fabric is iirst designed in the usual manner. The stops n on the slats m are then set so as to correspond with the pattern-that is, the stops regulating the use of one color of yarn are all preferably on one line on the slat and the stops of each other color are all preferably on their own particular line. Thedesign is changed, as desired, by changing the positions of the stops, which can be moved in or out on theslats in order to bring anyone of the yarn-tubes to the operative position, as heretofore described. The slats and stops form what may be called an adjust-able card. As has been described before, the forward movement of the frame o causes the stops n to engage and move forward the carriers c, so as to bring the vdesired yarn-tube to the operative position. As the carriers are moved forward their inner ends, which form a hook 57, engage and move inward a adapted to operate upon the tube-carriers, and means for bringing the stops of consecutive slats successively into 'engagementwith said tube-carriers.

3. In a figuring mechanism for looms, the combination of a connected series of slats, a series of transverse slots in each slat, a series of stops mounted in said slots in each slat, said stops being adjustable laterally of the slat and having projecting portions adapted to select the different yarns for the pattern, means for locking the stops in any desired relation on the slats, and means for moving the series of slats to bring them successively to operative position. i

4. In a figuring mechanism for looms, the combination of a connected series of slats, a series of transverse slots in each slat, a series of stops mounted in said slots in each slat, said stops being adjustable laterally of the slat and having projecting portions adapted to select the dier'ent yarns for the pattern, means for locking the stops in any desired relation on the slats, and means for moving the series of slats to bring them successively to operative position, a series of yarn-tube carriers and means for bringing said slats successively into engagement with said carriers.

5. In a figuring mechanism for looms, aseries of slats, a series of stops adjustably connected to one face of each slat, and having portions projecting from said face, a rotating support for said slots about which said slats ICO IIO

pass in radial arrangement, and means for l moving said support to give each slat an edge! wise forward reciprocation asit comes-into' operative position. 6. In al figuring mechanism for looms, the combination vWith a connected series of slats, a series of `adjustable stops mounted on each slat, and means for bringing the vsuccessive slats Vinto operative position, of a series of sets of yarn-carrying tubes, a movable carrier for each set, means'forbringing the slats into 'engagement With the tube-carriers to selectithede'sired yarn-tubes, and means for advancing each yarn-tube selected from its normal position to render the yarn carried more accessible. Y

lIn a figuring mechanismfor looms, the combination with a set of yarn-tubes, arranged side by side, and provided with projecting lugs, of an alining bar upon which lugs normally rest, said bar having in its edge anotch adapted to receive one of said lugs,l `means for moving the tubes' to bring a desired tube into position'opposite said notch, and means for depressing the selected tube to bring its lug into the notch.

8. In a figuring mechanism for looms, the combination With a fixed bar havinga notch in its upper edge and a movable bar havingl a projection corresponding to 'said notch, of the yarn-tubes, each having three projections or shoulders, means for adjusting said tubes to bring the selected tube opposite the notch movable bar to advance the selected. tube,

and means for raising'the selected tube into `alinernent with the remaining tubes of the set.

9. In a figuring mechanism for looms, the combination with a series of slats, each having a series of transverse -slots in one of its faces, of a sliding piece mounted in each slot, each sliding piece having an operative pro-Y jecting portion and a series of perforations by means of which it may be interlocked with the slat in dierent positions.

l0. In a gnring mechanism for looms, the combination with a series of slats, a rotating support for said slats, adjustable stops upon the slats, means for causing said slats to stand radially to the rotating support in passing around the same, means for imparting bodily movement to said support, whereby the operative slat is given an edgewise forward movement; of a series of movable yarn-tube carriers having portions extending into the path of the operative slat, said carriers being adjusted by the edgewise movement of said slat, the alining bar for the carriers, and a set of yarn-tubes mounted on each carrier.
