To all wwm/ t r11/cry concern.-

Beit known that 1, LON LETALLE, a citizen of the Republic of France, residing at Beauvais, in the Department ofV the Oise, Republic of France, have invented certain new and useful Improvements in Loom Shuttles, of which the following is a description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This specification relates to improvements in the shuttles used in looms for weaving longpile fabrics, and is a division of my application, Serial No. 385,934, filed March 20, 1891, and patented April 19, 1892,No. 173,261, and which shuttle has been patented in France January 13,1890, No. 203,116; in Great Britain January 20, 1891, No. 1,005; in Germany February 25, 1891, No. 59,821, and in Austria- Hungary February 7, 1891, No. 7,591 and No. 22,371.

The principal features of my invention are the circular spool for receiving the weftthread, the slotted plate and sliding deliverer therein, the convex-faced shoe for raising the warp-threads in depositing the chenille weft between them, the pivoted V-shaped delivery and leading tube, and also generally the improved construction.

In the drawings, Figure 1 is a top plan view of a shuttle embodying my invention, and also showing the catcher and part of the slide-bar for operating it, as in ordinary positive shuttle-motion looms. Fig. 2 is a front or side view showing the position of the spool and the general construction of the shuttle. Fig. 3 is an end view. Fig. 4. is a top plan view of a part of the shuttle, showing the pivoted delivery-tube and the convex deliveryshoe in section.V Fig. 5 is a detail showing the V-shaped groove in the pivoted deliverytube. Fig. 5 shows the chenille passing through the tube. Fig. 6 is a detail of the shoe and tube, and also shows the manner of its operation in depositing the chenille weft between the warp-threads. Fig. 7 shows the application of my device to the warp-threads of a loom. Y

In the drawings, h is the base-plate, from which the framing h rises, and which has the cross-piece b2 below the arch of the framing b', in order to furnish a bearing for the spindle or pivot of the spool or bobbn B', upon which is Wound the chenille weft. cut through the plate h, the sides of which widen toward the underneath face thereof. A shoe or guide c, havi-nga convex and rearwardly-inclined face, is provided with a guide g, which is dovetailed to lit into the slot sand guides the shoe from one to the other end thereof. Upon the shoe c is pivoted a tube t. This tube is so pivoted that its outer or delivery end describes a curve conforming to the convex interior of the delivery-shoe. The interior of the tube is V-shaped,with the apex of the V at the bottom. The convex face of the shoe c is slotted horizontally and the tube presents the chenille immediately at the rear of this slot, through which it passes out between the warp-threads. The shoe c raises the warp-threads in passing and they descend into the nap of the chenille,securingit in position until acted uponin the usual and well-known manner by the batten.

The chenille 'in passing through the V- shaped groove of the tnbet is folded upon itself, as it is under tension, and the warpthreads naturally have a tendency to be drawn down into the narrow part of the V of the groove. It therefore issues from the mouth of the tube and guide c, folded upon itself with its tufts upward, as they have been folded into and passed through the wider part of the V-shaped groove. As will be readily understood from the drawings, the shoe c will change its position from one end to the other of the plate b at every reciprocation of the shuttle, being free to slide in the slot s. With every change of position of the guide c the tube t will swing upon its pivot, and thus will deliver the chenille in a rearward direction from the travel of the shuttle.

In order that no more of the chenille weft be unwound than is necessary when the shuttle leaves the warp at either side of the fabric, the shuttle passes only far enough beyond the selvage to permit the hatten to pass.

my construction, in which the delivery is always from the rear end from the direction of travel of the shuttle, four or five centimeters is suflicient for this purpose.

A slots is I do not confine myself to the exact construction herein set forth, as many minor and detail changes might be made Without departing from the spirit of the invention.

Having described my invention, what I olaim, and desire to secure by Letters Patent, 1s-

1. A shuttle for delivering chenille weft, having 'a movable guide for the chenille delivered therefrom and a tube moving with saidguide through which the chenille passes, the tube being constructed With a V- shaped groove which folds the chenille upon itself in its passage vtherethrough.

2. In a loom, a shuttle having a movableV guide for the material Carried thereby and a tube pivotally attached to the said guide for delivering the material thereto, said tube swinging on its pivot at each change `of position lot' the guide.

3. In a loom, a shuttle having a movable gui-de for the material carried thereby, said for raising the Warp-threads in advance of its delivery-orice.

In testimony whereof I hereto afix my signature in presence of two Witnesses.

LoN LETALLE.
