LOON! FOR'WEAVING T UFTED FABRICS.

SPECIFICATION forming part of Letters Patent No. 288,266, dated November 13, 1883. I Application filed December 1Q,1S81. (1Y0 model.) I 7 To aZZ whom it may concern.-v Be it known that 1, CHARLES EDWARD SKIN- NER, of Yonkers, in the county of WVestchester and State of New York, have madean invention of certain new and useful Improvements in Looms for Weaving Tufted Fabrics, and in the art of weaving therewith; and I' do hereby declare that the following, in connection with the accompanying drawings, is a full, clear, and exact description and specification of the same. I i

This invention has reference to looms for weaving Moquette carpets and similar fabrics, in the weaving of which rows of tufts of colored yarns areinserted in and secured to the body of the fabric; and the object of the invention is to enable the ends of the rows of tufting material inserted from one side of the positionof the warp-threads in the loom to be turned toward the sidefrom which they have been inserted, so that both ends of the tufting.

material may be at the same side of the fabric. The invention consists of certain combinations of mechanical devices, and of a methodof raising the tufting material, which are recited in the claims at the'close of this specifi- In order that these combinations may be fully understood, I have represented in the accompanying drawings, and will proceed to describe, certain parts of a loom embodying the invention in the best form at present known to me. A

Figure 1 represents a longitudinal section of parts of the loom. Figsi 2, 3, and 4 represent detached portions of the loom, Figs. 3 and 4 being drawnupon alarger scale than the other figures.

- v As the invention has reference to particular portions of the loom, the other parts thereof may be constructed substantially as described and represented in the Letters Patent of the United States No. 186,374, with such variations only as may be necessary by reason of the present invention, as hereinafter set forth.

The warp and the weft threads or filling of the fabric may be held and operated substantially as they are in other Moquette carpet looms.

The tufting is by preference applied to a series of spools, which are carried by means of chains or other mechanism, and are presented in succession to the devices by which they are brought to and removed from the vicinity of the fabric for the purpose of having the tufts placed therein; Each spool is fitted in a spool frame or carriage, which is provided with a row of tubes or of needles, h, to hold the ends of the tufting material, and the frame should also be provided with a spring-brake to preventthe turning of the spool, except when the tufting material is pulled off it by the operation of the mechanism. In order that the spool-frame may be moved toward and from the place in the 100m at which the tufting is to be applied to the warp-threads, the loom is preferably provided with a pair of movable arms, K, (one at each side of the 100111,) which are connected with arockrshaft, K which is caused to rock so as to move the ends of the vibrating arms toward and from the position of the warp in theloom. Tlhe movable arms K are preferably provided with clutches to grasp the ends of the spool-frames,

and the said arms are preferably connected by pivots with the rock shaft arms K (one for each movable arm,) so that the first may be moved laterally in opposite directions to grasp and release each spool-frame in succession. The said movable arms are caused to move toward and from the position of the fabric by means of a cam, K operating upon said arms through the intervention of a friction-wheel, K, cam-lever K rodK, rock-shalt arm K, and the rock-shaft K and the lateral movements of the movable arms to enable them to grasp and release the spool-frames may beeffected by the same means as is described for that purpose in Patent No. 233, 290.

In order that the present invention may be embodied in the loom, it is provided with a bar, A, to act upon the ends of the tufting material which have been inserted between the warp-threads by the action of tubes h, or other appliances provided for that purpose; and the said bar is moved backward and upward in the loom, so as to bend the ends of the tufting material toward the side of the drawings the said bar A, which I call the 100 with the cam-shaft G of the loom.

. I wages bending-bar, is connected by connections a with the lay F ofthe loom, so as to be moved simultaneously with the lay. The lay is constructed to vibrate forward and backward, and it is operated at the proper times rela tively to the other mechanism of the loom by means of the lay-cam F, the friction-wheel f, the lever F*, the rod F, the lever-arm F, the rock-shaft F and the arms F, connecting the lay with the rock-shaft F, there being one of said lay-arms F at or near each end of the lay. The lay-cam F is secured to and revolves The backward movement of the lay is effected by means of one or more springs, F acting antagonistically to the lay-cam F?. j y

In the operation of the loom it is preferred to insert one row of tufting material for every four shoots of filling interwoven in the fabric, each shoot of filling being preferably formed of doubled yarn; and it is also preferred to use finer filling for holding the tufting material than the residue; hence the lay-cam F is constructed with four projections or points, f f

25 ff three of which, fff, operate the lay with a double beat for the coarser filling, while the fourth projection, f imparts to the lay a single beat for beating up the tufting material.

The cam K, which operates the transferringarms K, is so formed as to lower'the tubes h between the warp-threads .and to raise their ends slightly above the warp-threads, leaving the ends of the tufting material projecting through the warp-threads immediately before the shoot of tufting-filling is inserted in the shed,which has been opened by the heddles of the loom. Then the projection f of the laycam operates to cause the lay to beat up the shoot of tufting-filling. As the lay is moved backward in the loom after that beat, the bending-bar A (which is connected with the lay) is moved backward with the lay and also upward, so that the bar passes from the position in which it is represented in Fig. 1 to the position in which it is represented at Fig. 3, the upward movement of the bar being caused by its rocking upon the axis of the lay rock-shaft F as a center of motion. In this movement of the bending-bar itbears the ends of the tufting material backward and upward, as represented in Fig. 3, so that said ends are pressed upward between the warp-threads and are within their range of motion, the requisite movement of the bar for this purpose being attained by constructing the part 9 of the rim of the lay-cam succeeding the projection f sufficiently. depressed within the apex of the preceding projection f. As soon as the bar attains the position represented at Fig. 3, or thereabout, the warps are shifted (by the operation of the appropriate heddles) toform a new shed for the introduction of the next shoot of filling, and the rise of the warp-threads at each side of the tufting material for the formation of the new shed causes them to carry the ends of the tufting material with them to the positions represented at Fig. 4, so that when the said next shoot of filling, b, has been introduced into the shed the beating of it up by the lay causes this shoot to move forward beneath the upwardly-bent ends of the tufting material and forces them to an erect position in the fabric. As the lay beats up for this purpose, the bending-bar A is moved downward and forward in the loom, so as to be out of the way.

From the above description it appears that the return of the ends of the tufting materials to theside of the warp-threads, whence they .Were inserted between said threads by means of the tubes h, is effected by the co-operation of the bending-bar A and the lay F, in connection with the movement of the warpthreads, the bending-bar sweeping the ends backward and partly upward, and the lay com pleting the work through the intervention of the shoot of filling which the lay beats forward beneath and against said ends.

-It is not expedient that the bending-bar A, when operated through the intervention of the lay, should be moved as far backward andupward in the loom after each of the threeshoots of coarser filling has been inserted as it is moved after the insertion of the shoot of tufting-filling; hence the portions of therims of the cam F which succeed the projections f, for operating the lay for the coarser filling,

are not depressed as much as the portion 9 succeeding the projection f for operating the lay for the tufting-filling.

Although it is preferred to connect the bending-bar A directly with thelay, so that both are combined with and moved by the same cam, this direct connection is not essential to the first, second, third, and fifth parts of the invention, as said bar may be .operated by a special cam and spring appropriated to it and caused to operate upon it at the proper times by means of devices corresponding substantially with those through which the lay is caused to operate.

If preferred, the operation of the bendingbar may be repeated several times before the warps are changed.

I claim as my invention 1. The combination, substantially as b'efor set forth, of the series of tubes for inserting the ends of the tufting material in the warp with the bending-bar for bending said ends toward the side of the warp' from which they were inserted.

2. The combination, substantially as before set forth, of the movable arms for movingthe tufting material within the range of the bending-bar, and the bending-bar for bending the ends of said material.

3. The combination, substantially as before set forth, of the bending-bar for bending the set forth, of the bending-bar which bends the tufting material backward in the 100m, and threads are carried upward by said threads; the lay, with the lay-cam, whereby the first vand, fourth, movingforward said ends from two devices are both operated by the last. the positions attained by operation third to 15 5.
