7 To all whom it may concern.-

Be it known that LJAM-ES (3.;Ennrso1y, of Philadelphia, Pennsylvania have invented anew and useful Improvement in .Looms for Weaving Pile-Fabrics, of which the; following isa specification.

My invention relates to certain improvements in looms forweavingpile-fabrics,'the principal object of my invention being to so construct the thread-catching-devices as to insure theproper formation of the loopsat all times, and thus preventbreaks in the piled surface. This object I attain in the following manner, reference being hadto the accompanying-drawings,in which Figure 1, Sheet 1, is a side view of a loom with my improvements; Fig. 2, the same with the parts in a -different position; Fig. 3', Sheet 2, an end View Fig.4, a sectional plan on the line 1-2, Fig.3; Figsr5 -andt6, Sheet 1, detached views of parts of the loom; Figs. 7, 8, 9, and 10, Sheet 2, diagrams illustrating the formation of theloops andiFigsnll, 12, and 13, Sheet 3, detached views, drawn to an enlarged scale, of the loop-forming: devices.

A represents the breast-beam-of a, loom, and B the lay, carrying the reed D. To the beam at each endof vthe'same ,and-outside of the ne of Warp, is secured a box, E, and in each of these boxes slides a bar, a, the outer end of which carries asprin g-pin,a, which, under the circumstances described hereinafter, en-

ages with a hook,.c, onthelay B, so that as latter swings the bar is caused to recipate longitudinally in thebox E.

i From the under side .of the bar to projects a pin, b,.,Fig. 5, this pin being adapted to a slot in a plate, 01, which forms the bottom of' the box, the slot being inclined at the front end, as shown, so that as the bar approaches or reoedes from the limit of its forward movement a lateral vibration is imparted to the bar and to the parts carried thereby.

Each bar a carries a supplementary bar, arranged on the innerside of the box E, and

' to these bars a are hung the opposite ends of a rod, 6, to which are pivoted arms 6, carrying at their outer ends a bar, 0 the latter being provided with a row of projecting fingers, '5, each of which has, near the end, an openg, onaplate, G, but during the rearward movement bears uponthe upper side of said rib.

The bar. 6 is connected to the lower ends of rods f, pendentfroin the front ends of rods J, which .are guided in. suitable lugs on the boxes E, so as to movepn .an angle, movement being imparted: to. the rods J from the rear ends of the bars a, to which said rods J are loosely connected.

Some of the warp-threads as are raised higher than the other threads, y, as is usual in weaving piled fabrics.

In the operation of the loom it is desirable to move the lay at intervals Without operating the bars a, as described hereinafter; and in order to do this the hooks 0 on the lay are .lnovedllaterally until they are out of line with the spring-pins a on the bars a. This operation-of the hooks is effected by the adjustment of a forked plate, 8, hung to the breast-beam, and acting on a pin, 10, on the slide q, carrying the hooks. (See Fig. 4..)

The operation of the fork at the proper in tervals is efl'ected by a cam, t, on the shaft it, through the medium of the arrangement of rods and=levers, clearly shown in Figs. 1, 2, 3, and 4;. a

The cam t acts on a pivoted arm, 2, the outer end of which is depressed by a spring, 3, so as to keep the arm always in contact with the cam.

The arm 2 is connected to a vertical bar, 4, the upper end of which is attached to an arm, 5, on a rock-shaft, 6, another arm, 7, on which is connected to one end of a rod, 8, the opposite end of which is jointed to the forked plate 8. The lower end of the bar 4. is connected to one arm of a lever. 9, pivoted to the frame of the loom, as shown in Fig. 3.

The result of the operation of the loom will be understood on reference to Figs. 7,8,9, and 10.

As the bar 0 and its fingers z" are moved forward the fingers are thrust into the raised threads as of the warp, as shown in Fig. 7, and at the forward end of the movement a lateral throw is imparted to the bars a, and consequently to the bar 6- and the fingers i, the latter being thereby thrust laterally under the threads as, which then lie over the fingers. as shown in Fig. 8. While these operation were being performed the front end of the lever 02 and the frame F, carrying the pins m, were elevated; but when the fingersi are moved to the position Fig. 8, the pin at the rear end of the lever 02 will have reached the front end of the rib g on the plate G, and will rise, thus allowing the pins m to descend and enter the openings in the fingers i, so as to firmly retain on said fingers the threads which they have caught. The fingers now commence the return movement, first moving laterally, as shown in Fig. 9, and then longitudinally until they reach the position shown in Figs. 1 and 10, the front ends of the fingers being then somewhat in the rear of and above the front edge of the woven fabric 2, so that the warps x, which the fingers carry, form loops.

While these operations are being performed the plate 8 has been shifted, so that when the parts reach the position shown in Fig. l the slide g has been moved to such an extent as to free the spring-pins a of the bars a from the control of the hooks c on the lay, and several picks are woven plain before the loops are released and the parts again thrown into gear prior to the formation of another set of loops in the same manner.

The object of weaving several picks plain between the rows of loops is to firmly bind the latter and prevent them from being pulled out.

A pivoted tappet, to, Figs. 6, 11, 12, and 13, operated by a rod, 10, from the lever 9, Fig. 3, is employed in order to effect the movement of the pin at the rear end of the lever n from the upper to the lower portion of the rib g on v the plate G, at the rear end of the same, the

pin rising automatically from the lower to the upper portion of the said rib at the front end of the plate, owing to the preponderance of weight at the front end of the lever if.

The fingers i and pins m may be duplicated on the under side of the shed, if desired, in

order to form loops on both sides of the fabno.

I claim as my invention- 1. The combination of the bar 0 having fingers i, the frame F, having pins m, and de vices for supporting and operating the said bar and frame, so as to cause'the fingers and pins to catch and release the threads, all substantially as set forth.

2. The combination of the bars a, the lay B, devices whereby the lay is caused to operate the bars, the bar 0 having fingers t, devices for connecting said bars a and 0 the connecting-rods f, the rods J, and means for supporting and guiding said bars a and rods J, as set forth.

3. The combination of the breast-beam A, the boxes E, the bars a, the supplementary bars M, the rod e, the fingers e, and the bar 6 carrying fingers i, as set forth.

4. The combination of the bars a, provided with pins b, the bar 0 having fingers i, devices for connecting said bar 0 to the bars a, the boxes E, provided with plates 01, having slots inclined at the front ends, the breast-beam A, and mechanism for longitudinally reciprocating said bars a, as set forth.

5. The combination of the bar 0 having pins n and fingers i, the frame F having pins m and sleeves n, the forked arms M, and devices for operating the same, as specified.

6. The combination of the lay B, having a slide, q, carrying hooks a, the bars 0, having pins a, the forked plate 8, for shifting the hooks, and devices for operating said plate and the lay, all substantially as described.

7. The combination of the breast-beam A, the boxes E, the bars a, the bar 0", carried thereby, and having fingers t, the frame F, having pins m, the lever 11, the plate G, having a rib, g, and devices for reciprocating the bars a, all substantially as set forth.

8. The combination of the plate G, having a rib, g, the frame F, means for supporting said plate and frame, the lever n, the tappet w, and devices for operating the tappet and reciprocating the frame, as described.

In witness whereof I have signed my name to this specification in the presence of two subscribing witnesses.
