LOOM FOR WEAVING TUFTED FABRICS.V

SPECIFICATION forming part of Letters Patent No. 343,111, dated June 1, 1886.

Application filed September 8, 1884. Serial No. 142,487. (No model.)

.To all whom it may con/cern,.-

Be it known that we, GEORGE GRoMrToN and HORACE VYMAN, of the city and county of Worcester, Massachusetts, have invented an Improvement in Looms for Weaving Tufted Fabrics, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to looms of the class adapted for the production of tufted fabricssuch, for instance, as moquette carpete-the object of the invention being to improve and simplify the means for controlling the tuftyarns, in order that the same may be taken directly from independent spools or bobbins, one for each yarn, thus obviating the beaming of yarns of different colors on separate warp-beams, one for each transverse row of tufts, and also dispensing` with the beamsupporting chains and moving devices therefor, as heretofore usually employed.

This invention consists, essentially, in a series of carriages arranged side by side, means to move them varying distances in the direction of the length of the warp-threads, and a series of tuftyarn carriers or needles arranged in the said carriages, one behind the other, in the direction of the length of the warp, combined with cutting mechanism to cut the tuft-yarns, and with nipper-like plates to seize the ends of the tuft-yarns and carry and place the tufts between the warps after they are cut into tuft-forming lengths, as will be hereinafter described. Other features of our invention will be hereinafter described, and pointed out in claims.

Fig-ure 1 is a vertical section of a sufficient portion of a loom to enable our invention to be understood. Fig. 2 is a partial front elevation of the loom shown in Fig. l'. Fig. 3 is a detail showing a carriage, tuft or yarn carriers or needles therein, a pattern-barrel, pattern-cards, and jaws to draw off the tuft-yarns, the same being in different position from that represented in Fig. l. Fig. et is a detail showing the devices to rotate the barrel. Fig. 5 is asectional detail in the line xx, Fig. l, showing several carriages side `by side on their' rests and holding tuft-yarn carriers or nee- 5o dles. Fig. 6 is an enlarged detail to be referred to. Fig. 7 is a detail plan view of a sufcient portion of a loom to show the manner of operating the springnippers instrumental in introducing the tufts; Fig. 8, a detail of part of the devices represented in Fig.

7 and Fig. 9 an enlarged section showing the nippers.

This invention is intended as an improve ment upon the loom Vdescribed in United 6o States Patent No. 251,304, to which reference may be had.

Referring to the drawings, the frame-work A, cam-shaft S, lever G5, rod g", arm G2, rockshaft G3, levers G G plates g2 g2, to engage the ends of the tuft-yarns, links c* 0*, arms g9 gi, with which they are connected, shaft GS, arm 97, link g, connected with lever G7, the cam Gr, the tuft-cutting mechanism composed of the blades H HF, the slides H Hit, rods h4 h", lever hl, pivoted at hs, shaft H5, having arms h h, rod hifi, extended downward and connected with lever HL, the cam H3, and the nippers having the plates n n', springs as a8, jaws N N, extensions a5, rod n', pinion ji, sliding rack ji, roller j, arms N', rock shaft N2, rod i4, lever I', cam I, lever J, cam J, rod j', elbow-lever J2, and pin j, the lay L, link L3, cam K, projection H3, lever K, pivoted at 7c, link k', elbowlever K2, rod kx, sliding connecting-rod k2, guide k3, pin kt, horizontally-moving lever K3, having its fulcrum on one arm, N', and connected with rod nl, and its cams or wedges a, to enter between the extensions a5 of the jaws N N, are all substantially the same as the parts designated and described by like letters in the Patent No. 251,304, except that the link c shown in the said patent is herein marked 0X, and in a working-loom embodying the invention hereinafter claimed the said parts will be operated by mechanism such as f ully described and shown in the said patent, and hence not herein illustrated in detail, the said parts, when embodied in our improved loom, operating as in the said patented loom to manipulate the tuft-yarns.

Desiring to dispense with the long chains and the series of spools, of which there is one for each transverse row of tufts to be made in the productionof the pattern in the fabric as contemplated in the said patent, each of the said spools having tu'ft-yarns wound thereon in the order of the colors to appear in some one transverse row of tufts, we have provided the loom with a series of carriages, E,arranged side by side in grooves of rests or bars 109, the said carriages being free to be slid or lnoved backward away from the breast-beam and .in the direction of the length of the warp by the action of a pattern surface, to be described, it acting upon one or the other of a series of projections, 2 3 4 5 6 6X, extended horizontally from the end of each carriage, as shown best in Figs. 1 and 3. Each carriage has a stop, 7, which is normally kept pressed against one of the bars or rests 109 by a spring, 8, connected at one end with a pin, 9, attached to the carriage E, and at its other end .with a rod, 10, held at each end by a bracket, as at 55, secured to the frame 12, which supports the shaft 14` of the hollow hexagonal barrel 13, preferably composed of metal plates joined to head-pieces. the latter receiving the shaft 14. Each of the plates composing the barrel 13 is provided, as herein shown, with six longitudinal rows of holes to correspond with the six projections 2 to 6X, inclusive, of each carriage, there being as many holes in each longitudinal row of holesas there are carriages E in the series of carriages from side to side of the loom, there being as many carriages as there are tufts in each transverse row of tufts. lnpractice we find that but ve rows of holes and five projections are necessary, as the projection 2 may be omitted and the carriage rest against the pattern-surface when the needles c5 are to be operative. But one end of the shaft 14 is shown in the drawings, and in practice the other end thereof will be supported in like manner as shown.

The shaft 14 shown in the drawings is pro- `vided with a bevel-gear, 16, and with a wheel,

17, having pins 18, which are engaged by a pawl, 19, pivoted at 21 on a standard, 20, attached to the loom -frarne near the breast-beam 22. The bevelgear 16 engages a bevel-gear, 23, on the upright shaft 24, held in bearings attached to frame 12. The upper end of the shaft 24 has a bevel-gear, 25, which engages a bevel-gear, 26, on a shaft, 27, having upon it a barrel, 2S. The shaft 27 has a toothed wheel, 29", which engages a toothed wheel, 30, on a shaft, 3l, provided with a third barrel, 32, and below this barrel is a suitable cradle, 33, to support the chain of pattern-cards 29 in usual manner, the said barrels being operated to move the chain of pattern-cards intermittingly. The pattern-cards 29, connected together in the proper order and constituting the pattern-surface, are each provided With holes, some of which coincide with those of the barrel 13; but each pattern-card serves to close one or more of the holes of each vertical-row of holes in the barrel, the parregular intervals by link 35, attached in practice to the shaft 14 of the barrel 13, and to the elbow-lever 36, mounted loosely on a shaft, G, the said elbow-lever being connected by link 38 with a lever, 39, pivoted at 40, and acted upon by a cam, 44, these parts being duplicated at opposite sides of the loom. As the barrel is swung outward by the devices described, the hooked pawl 19, in engagement with a pin, 18, effects the rotation of the said barrel, bringing a new card in position with relation to the projections 2 3 4 5 6 6X.

The carriages are provided at one side with pins es, leaving spaces between them, which constitute pockets or grooves for the reception of a series of tuft carriers or needles, c to c5, inclusive. These pockets receive and guide the tuft carriers or needles c to c5, respectively arranged in a row, one back of the other, as shown best in Fig. 1.

The points of the tuft carriers or needles are made as flattened tubes, having eyes for the delivery of the tuft-yarn, and above their ends the carriers or needles are composed of wire having at their upper ends eyes 40, by which they are suspended upon rods or wires 41, each carrier or needle having an intermediate guide-eye, 15, through which is led the tuft-yarn t, the tuft-yarn entering the eye of each needle coming in practice from an independent spool or cop containing 'but one yarn, the spool or cop being supported upon a frame, a's described and shown in our application No. 136,604, filed July 2, 1884. Herein the tuft-yarn carriers or needles which receive the tuft-yarn through them are placed under the control of carriages', and the said tuft-yarn carriers or needles are of such length as to hold the said yarns frictionally, so that when the yarns are cut off outside the carriers or needles they will not slip back. After the formation of each row of tufts the barrel 13 and pattern-cards are moved to the left, viewing Fig. 1, by the spring 42, connected with the lever 39, before described, and the barrel is turned one step, bringing a new card in working position. The projections 2 to 6X are of different lengths, their difference being substantially equal to the distance from center to center of the different tuft-yarn carriers.

KOC

IIO

In Fig. 1 the barrel 13 is shown as moved f 1, the rearmost needle, c5, of the series of needles being nearest the plates g2 gl of the levers G GX. The barrel 13 has a hole for each projection 2 to 6X, inclusive, and the pattern card, by covering one hole in the barrel opposite the Aseries of projections of each carriage, acts to arrest or prevent one or the other of the said projections from entering the hole prepared for its reception in the barrel. The distance which the barrel and card will move the carriages backward'vfrom the breast-beam depends upon which of the projections 2 to 6X is acted upon by the card. The projections 2 to 6 respectively control the placing of the needles c5 to c respectively in working position, or so that the tuft-yarns carried by them may be taken by the nippers which rise between the levers G GX,Kas in the patent referred to, No. 251,304.

In Fig. 3, wherein the barrel is shown as moved backward or away from the front of the loom, the projection 5 is shown as acted upon by the card, thus placing the tuft-yarn carrier or needle ci of the series in operative position. lf the projection 6 were arrested, the carrier or needle c would be in operative position, and if projection 2 the carrier or needle c5 would be in operative position.

Fig. 6, on a larger scale, shows the lower ends of the series of tuft-yarn carriers or needles with the tuft-yarns protruding from them,and with the yarn of the carrier or needle cZ caught by the plates gl g2, which, as herein shown, are employed to draw the tuft-yarns for a short distance from the needles, holding them in a row,while the nippers, with the plates u n separated and pointed upward, are made to grasp the row of the tuft-yarns in the set of carriers or needles which have been placed as described in working position, a carrier or needle of each carriage, the movement of the latter for a greater or less distance placing in working position that one ofthe series of needles containing the tuft-yarn of the color which it is desired that each carriage, from one of its needles, shall furnish in the production of the transverse row of tufts to be made. The nippers having been raised at each side of the row of tuft-yarns, and having been operated to grasp or seize the tuft-yarns, the latter are cut off by the blades H Hifi, and the nippers are lowered and turned downward,

bringing them into position above and so as to pass the tufts carried by them between the warp-threads, to be woven into and form part of a fabric, as fully described in the said patent.

In another application, Serial No. 179,213, filed October 7, 1335, we have shown a series of carriages provided with openings or passages i'or the reception of the tuft-yarns, the tuft-yarns cominginto the said carriages from guides independent of the carriages, and in the said application the carriages are moved said application we have claimed the said devices broadly, this present application being intended to be subordinate to it. So, also, in another application, Serial No, 136,604, we have shown and claimed a series of carriages containing independently movable tuft-yarn carriers or needles adapted to be selected by a Jacquard mechanism.

1. A series of carriages arranged side by side across the loom, a series of tuft-yarn car riers or needles arranged in the said carriages, one behind the other, and holding the tuftyarns, combined with means, substantially as described, to automatically move the said carriages horizontally or in the direction of the length of the warp for different distances, whereby any desired one of the carriages may be made to present any desired one of the tuft-yarn carriers or needles in position to be seized by nippers, and with nippers to engage the tuftyarns below the under sides of the carriages, substantially as described.

2. A series of carriages arranged side by side, means, substantially as described, to move them automatically for varying distance/s, and a series of tuft-yarn carriers or needles arranged therein, one behind the other, in the direction of the length of the warpthreads, combined with cutters or blades to cut the tuft-yarns, and with nippers to seize the tnft-yarns and carry and place the separate tufts between the warps, and with means to actuate the said cutters and nippers, substantially as described, whereby the` nippers, when turned upward, are opened to embrace the tuft-yarns, and are subsequently turned downward to introduce the short tufts held by them between the warps, as and for the purpose set forth.

3. The series of independent tuft-yarn carriers or needles, means to support them, the sliding carriages E, provided with projections of different lengths and moving the said tuftyarn carriers or needles, rests upon which the said carriages are mounted side by side, combined with means, substantially as described, to move the said carriages and tuft-yarn carriers or needles in the direction of the length ICO IIO

of the warp and for different distances, and

with the nippers, and means, substantially as described, to open and close and partially rotate them, whereby they are caused to place the tuft-yarns cut into tuft-lengths'between the warp for the formation of tufts, substantially as described.

4. The rests and the carriages thereon, comi said carriages, combined with means to act upon and move the carriages different distances in the direction of the length of the warp, to thus place any one of the series of needles of each carriage in position to furnish a. tuftyarn of the proper color for the production of the transverse row of tufts next to be inserted, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of ro two subscribing witnesses.
