LOOM.

SPECIFICATION forming part of Letters Patent N 0. 691,370, dated January 21, 1902. Application filed September 12. 1901. Serial No. 75,148. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM FISCHER, Jr. a citizen of the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Looms; and I do hereby declare the following, to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towh-ich it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates to looms; and it has reference particularly to and consists in certain hereinafter-described improvements in looms in which in order to avoid the frequent replenishing of the weft which is occa sioned where the same is taken from bobbins in the shuttle or shuttles said weft is supplied from bobbins arranged separately from the shuttle or shuttles in some other stationary part of the loom.

The invent-ion will be found fully illustrated in the accompanying drawings, wherein Figure l is a vertical sectional view of my improved loom. Figs. 2 and 3 are respectively a view in front elevation, slightly broken away, of one end of the batten or lay structure and a vertical sectional viewof. said batten or lay structure, taken, opposite one of the lay-swords. Fig. at is a plan view of said batten structure and of the web. Fig. 5 is a diagrammatic View illustrating the weave, and Figs. 6 and 7 present details of the invention.

In said drawings, a designates the loomframe; I), the main drive-shaft; c, the camshaft; cl, the batten; e, the lay-swords for the batten fulcrumed at f and operated from cranks g on shaft 1) through pitmen h; 7:, the breast-beam; j, the take-up roll; it, the warp-beam; Z, the harness, and m the pickersticks. These various parts are arranged and operate substantially as usual. It may be remarked, however, that the shafts b and c are connected by intermeshing gears 91 and o, of which the latter, being carried by the shaft 0, is twice the diameter of the former, so that one revolution of the shaft 0 means two of the shaft b.

p designates the warp.

The shuttle which I employ in my improved loom has the same outward appearance as the ordinary shuttle except that it carries no quill or bobbin, there being provided instead in a vertical cavity q in the middle portion of the shuttle A a catch r,which is normally held in vertical position on its pivot s by a weight 25. When the pickerstick sends the shuttle across the batten, the weighted end i of the catch trails on the top of the batten, making the catch assume the position illustrated in dotted lines in Fig. 6; but when the shuttle is over the opening'u. in the batten which accommodates the picker-stick said catch assu mes its normal or verticalposition, as shown in full lines in'Fig. 6. In order to facilitate the action of the catch, the ends of the portion of the top surface of the batten against which it wipes are beveled downwardly, as at c, Fig. 2.

The weft or filler is taken from bobbins 20, arranged on suitable stands as at the back of the loom and, under control of suitable tension devices y, is passed up and over a rod 2 for the warp and then forward to the batten, where it extends through an openingl in the back wall thereof to the web.

In the portion of the batten preferably opposite each lay-sword and in a separate block 2, secured at this point above and to the batten proper, are formed opposed recesses 3, forming a race for a vertically-movable shuttle B. The race for the shuttle A crosses the race for the shuttle B, which, being provided with rack-teeth 4, is adapted to be actuated from a rack-bar 5, through pinions 6, journaled in the batten and each block 2. The rack-bar works longitudinally in guides 7 on the corresponding lay-sword 6, being reciprocated from a lever'8 through a connectinglink 9. The lovers 8 for the rack-bars have their free ends provided with roller-bearings 10, which engage the periphery of reversed cams 11 on the shaft 0. Owing to the nature of the gearing between the shafts b and cand the disposition of the cams '11, the action of each shuttle B is one which consists in a movement which is an np-and-down one to every movement in one direction of the shuttle A. It is to he understood that the shuttle B is designed to provide a locking-thread to the weave and that it carries its own supply.

It should be remarked that the weft-thread preferably passes around thread-guides 12, which hold it at the proper time in the proper position relatively to the shuttle A. When the shuttle A is shot across the batten, therefore, though it passes under the weft-thread clear of it, its catch 1' engages the thread, and as the catch is depressed during the advance of the shuttle into the position shown in-dotted lines in Fig. 6, as already described, said thread is held securely and carried through the warp-shed to the other end of the batten. When the shuttle reaches the other end of the batten, the weight tis free to drop into the adjoining recess a, and the action of the thread tends to reverse the position of the catch, so that said thread will slip off; but just before the thread is detached from the catch the adjacent shuttle B is driven downwardly (see Fig. 5) through the loop thus formed in the weft-thread, thus serving to bind it with its thread. Immediately upon the release of the weft-thread from the catch the shuttle B is returned to its original position. Thus in so far as the weft is concerned the weave is produced by the shuttle A carrying the weft-thread through in a succession of loops, each of which is held in place at the end by a separate thread supplied by the shuttle B,the loops alternating with the crossings of the warp. Though one weft-thread may be employed, it is preferred that in producing even plain goods at least two weftthreads be employed, as shown in the drawings, Fig. 5, one being supplied from each side of the web.

It may be desired to introduce two or more weft-threads from either or both sides of the web of different qualities or colors, and with thisobject I have provided the following mechanism: 13 designates a bracket, which is preferably mounted at each side of the loom substantially in the plane of the warp and in which is fulcru med a series of thread-guides 14:. 'Each of these thread-guides is provided at its free end with a thread-eyelet 15, through which extends one of the weft-threads C0111- ing from the bobbins to. In the bracket 13 is journaled a ratchet wheel 16, which is adapted to be advanced step by step by a hook 17, which may be carried by the batten, a reverse turning of the ratchet-wheel being prevented by a pawl 18. Arranged to turn with the ratchel-wheel is a notched disk or star-wheel 19, which carries a pattern-chain chain, and their position is adapted to be eontrolled thereby.

The efiect produced by the thread-guides under actuation of the pattern-chain is to elevate or lower their respective threads, according as they are to be carried or not to be carried through the warp-sheds in loops. If they are to be carried through the shed, their respective thread-guides are in the lowered position'i. e., within the path of movement of the catch 1' on the shuttle. If they are not to be carried through the warp-shed, they are raised by the thread-guid es to a position out of reach of said catch.

I do not wish to be limited to the exact construction shown and described; but

WhatI claim as new, and desire to secure by Letters Patent, is-

1. In a loom, the combination of warp-controlling means, a weft-supply, a batten,a shuttle arranged on said batten, the weft-thread being adapted to extend across the path of the shuttle on the batten, a movable weft-catch pivoted in said shuttle, and means for moving said catch to engage and disengage the Weft as the shuttle moves across the batten, substantially as described.

2. In a loom, the combination of warp-controlling means, a weft-supply, a batten,ashuttle arranged on said batten, the weft-thread being adapted to extend across the path of the shuttle on the batten, a weft-catch pivoted in said shuttle and projecting from the same, and means for oscillating said catch as the shuttle moves across the batten, substantially as described.

3. In a loom, the combination of warp-controlling means, a batten, a shuttle arranged on said batten, said batten having a recess in, and the weft-thread being adapted to extend across, the path of movement of said shuttle on the batten, and a weft-catch pivoted in said shuttle and normally held vertical projecting above and below the shuttle, the upper end of said catch being adapted to engage the thread and the lower end being adapted to engage the batten to depress said upper end, substantially as described.

at. A loom-shuttle consisting of a body portion in combination with a catch pivoted in said shuttle and adapted to project out of the same at both ends, one end of said catch being adapted to engage the weft-thread and the other a part of the loom so as to depress said'catch, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 30th day of August, 1901.
