SPECIFICATION forming part of Letters Patent No. 364,860, dated June 14, 1857.

(No model.)

two shuttles are actuated positively .one at each v side of the loom, the said shuttles being alternately inserted into and then withdrawn from acentral shuttle-box located at or near the center of the length of the lay, provided the two pieces of rcloth to be woven are to be of the same width, my invention being especially applicable for weaving wire-cloth. The application of a shuttle-box to the lay between the usual shuttle-boxes at its ends also enables me to utilize broad looms for weaving two narrow fabrics, each fabric having two well-finished selvages. A woven-wire fabric having a regular selvage at each edge is much more serviceable than a fabric yvith but-one selvage, such as is commonly produced by weaving a fabric on a broad loom and then splitting it longi- In accordance withiny invention, as herein embodied, each shuttle as it is inserted into the central or intermediate shuttle-box acts to push the other shuttle then in it partially out, so as to be readily taken by its carrier, each carrier when inserting a shuttle into the intermediate box travelinga little farther than when about to take a shuttle from the intermediate box, the difference in the length of the stroke of the carrier for such purpose being made by shifting the fulcra ot' the levers or picker-sticks which actuate the said carriers, as will be described. rEhe novel features above described, and forming the subject of my invention, will be hereinafter described more fully, and be speeilically pointed out in the claims at the lend of this specification.

Figure l in front elevation represents aloom embodying my invention, the breast beam and front part of tlleloom-fralne being broken out; Fig. 2, a detail and partial elevation taken from the front of the loom chiefly to show part of the reed, the intermediate shuttlc-box, a shuttle therein, the shuttle-holder, and the shuttle-boxes at the ends of the lay, and the carrier to move the shuttle,the carrier at the right hand of Fig. l having a shuttle. Fig. 3 is asection of Fig. l in the dotted line x :v Fig. 4 is an enlarged detail of the shuttie-holder, the dotted line therein indicating part of a true circle; Fig. 5, a top or plan view of. one of the shuttles, partly broken out,

together with a part of one ot' the carriers- Fig. 6 is a front elevation of the devices shown in Fig. 5. Fig. 7 is a sectional detail in the line at? of Fig. 6, looking toward the left. Fig. 8 is a top or plan view of a portion of the intermediate shuttle-box,whicl1 is open at both ends; Fig. 9, a front elevation of the intermediate shuttle-box; and Fig. 10 is a detail of one of the cam-disks, its shaft, and attached gear for actuating one of the pickersticks or levers.

The frame-work A, of suitable construction to support the working parts, has a lay or crank-shaft, A', upon which is mounted usual fast and loose pulleys, (see Fig. 1,) to receive a belt upon which to rotate the crank-shaft, and through the links B vibrate in usual inanner the lay B', pivoted at BZ. The crank-shaft has fast upon it a toothed gear, C, which e11- gages a toothed gear, C', on the cam-shaft C, provided with cams a a, which act upon rolls a', mounted upon levers a, pivoted at et, there being two such cams and levers, one lever being attached by usual cording, 2, to a harnessframe, b, while the other lever is attached by usual cording, 3, to a harness-frame, b', the said harness-frames being joined by cording- 3X, passing over suitable rolls, b2, on brackets b3, supported upon an arch, A, at the top of the frame -work, the said harness-frames having usual heddles `provided with eyes for the reception of the warp-threads w, the said harness-frames forming the shed in the warpthreads for the passage of the shuttle or shuttles, to be described, the two harness-frames herein shown being capable of manipulating the warps for what is known as plain weav ing.7 The warp-threads come from one or more beams or spools, supported in usual manner at the rear side of the looni-frame.

The shed-forming mechanism, hereinbefore described, and the mechanism for moving the lay are not ofmy invention, and, instead of being made as shown, may be of any other' usual or suitable construction, according to the class of material to be woven.

Herein I have shown my invention as applied to the weaving of w'irecloth, a class of cloth for which myinvention is especially applicable; but I desire it to be understood that my invention might be employed in weav- :5 ing fabrics of other material than wire. rlhe lay B has a reed, c, held therein in usual manner. Near the center of the lay I have erected an arm, r, which is extended over the top of the reed and rests upon or is secured to its z 3 cap c. The arm r has secured to it by a screw, r', aspring-arm, 4, upon the front end of which is loosely pivoted the shuttle-hclder'or check d, consisting of a cam shaped plate, (see Figs. 1, 2, 3, and 4,) the periphery of which is normally kept pressed toward the race ol' the lay by means ot' the said spring 4, lateral movement of the spring being prevented by the projections 5 rising from the reed-cap c. This holder is so mounted upon the spring-arm 4 3o that when permitted to do so it will gravitate into the position shown in Fig. 4-that is, it will hang with its points in the Same horizontal plane. Viewing Fig. 4, it will be noticed that the holder is of shorter radius vin the line y y than in the line y y, so that as the said holder is turned by contact against it of a shuttle, the periphery of the holder of greater radius will come gradually into contact with the shuttle and act as a brake to stop the 4o shuttle at a certain spot in the said box.

'I`o the lay,and,as herein shown, nearits center, I have attached by screws 6 an intermediate shuttle-box, e, it being made as a plate to embrace the front edge of thc race of the lay,

'45 and when desired the said plate may be shaped to extend partially over the race of the lay. A portion of the said plate is extended upward, as at c', to constitute a wall or flange, against which the front ofthe shuttle may bear, 5o to prevent the same flying off the front side of the race of the lay, the rear side of the shuttle acting against the front side of the reed. The intermediate shuttle-box,e, referred to, is open at both its ends, and is located directly below the holder d. The wall or flange c of the intermediate shuttle-box is beveled, as at 7, to act upon the curved part S of the springlatchf, as the shuttle s enters one end of the said intermediate box, thus pushing in or 6o backward the said latch, (shown as ont or forward in Fig. 5,) until the hooked part 9 of the latch is pushed in far enough to be disengaged from the shoulder 10 of the socket-head q of the carrier, the said shoulder being formed by cutting a recess, l2, in the said soeketed head. The carrier is composed of a socketed head, g, and a rod, g', the soeketcd head bei ng preferably cylindrical externally, whereas the rod is of dovetailed shape in cross-section, as best shown in Fig, 7, the rod entering acci-respondinglyshapcd guide in a guide-plate, g, provided at its end next the lay with a recess or chamber, as gi, which constitutes ashuttle-box or receiver for the shuttle when the carrier is thrown outwardly, as represented by dotted lines in Fig. 1, the shuttle at such time being drawn into the said recess outside of and beyond the ends ofthe lay. The sh uttle s, herein shown, has usual delivery-rolls, 13,at its front side, between which passes the wire or other material contained upon asuitable cop or ball of usual construction, supported in usual manner within the frame of the shuttle, the said cop or ball being omitted because not of my invention. The shuttles has at but one of its ends a projecting arm, s', preferably of conical shape, as shown in Figs. 5 and 6, the said arm entering a conical hole in the socketed head g ofthe carrier, one side of the said arm being grooved in thedirection of its length to permit -the latch j' to be pushed back into it when it is desired to release the latch from thesock eted head g of the carrier.

Prior to my invention carriers such as described and shuttles, substantially such as described, but provided at both ends with an arm or projection, s', andalatch to be engaged by the carrier, have been used, one carrier, however, taking the shuttle directly from another carrier at or near the centerolthelay in the shed. IIereinit willbe noticed that the inner end of each shuttle s is left to present a flat end or wall, 1 4, which may be abntted against the corresponding inner end of another sluittle, 1 held in the intermediate shuttle-box, c, by the holder d.

Referring to Fig. l, it will be understood that the shuttle s is held by the holder (l in the intermediate shuttle-box, and that the shuttle il has just struck against the shuttle s, the carrier g', attached to thelever or stick 1f, not yet having reached the full extent of its stroke. rIhe farther movement of the stick t to the right, with its attached carrier, will canse the shuttle t to push against and move the shuttle s to the right and force its projection or arm s into the socketed head g of the carrier to receive it at the right of the loom, the movement of the shuttle s, by the blow against it of the shuttle being sufficient t0 carry the bnlged part 8 of the spring-latch fbeyond the straight' inner edge, 18, of the intermediate shuttlebox far enough to permit the hooked part 9 of the spring-latch to move outward and engage the shoulder l() of the socketcd head placed there to receive the said arm s', and thereafter the lever or pickerstick s'A is moved to the right, viewing Fig. l, taking with it the carrier g', the socketedhead thereof holding the arm s and taking the sluittle s from the intermediate shuttle-box outward. The shuttle t will be moved to the right far enough to carry the spring-latch f past the round eorner7 and against the straight -lOC shuttlabox, the carrier will be withdrawn as the picker-stick is next moved outward or away from the loom-frame, but the shuttle will be left in the intermediate shuttle-b0x until pushed partially out ofthe said shuttle` box by a second shuttle. A new shed will be formed after the outward movement of each picker stick or lever, after which the carrier will be again moved,so that thelatter will pass through the new shed toward the intermediate shuttle-box to take a shuttle therefrom and bring it backk through the shed last formed. The picker-sticks t and s2 have their fulcra upon a slide-bar, ainthc bearings h' at the bottom ofthe loom-frame, the said pieken sticks being pivoted upon the said slide-rod, as at 17. roller or stud, 38, which enters a cam-groove, 19, in a plate or disk, 20, thecam-groove being of such shape (see Fig.`1) as to cause the said picker-sticks to be moved at their upper ends for a distance suftcient to actuate the carriers and pass the shuttle through the shed in the warp and into theintermediate shuttle box, as described, and back again.

From the foregoing description it will be noticed that the carrier having a shuttle attached to itand passing from the outer end of the lay toward Athe intermediate shuttle-box has to have a movement sufficient not only to knock' the shuttle from the intermediate box, but also to carry the shuttle far enough into the intermediate box to enable the wall 18 of the latter topnsh inward the spring-latch and disengage the shuttle so being entered into the intermediate box from the carrier which placed it there, so that the carrier could return without it. The carrier approaching the intermediate box to take a shuttle therefrom 'is not moved as far as when it approaches the intermediate box t0 leave ashuttle. This difference in the alternate throws of the carrier is provided for by sliding the bar 7L laterally in one and then in the other direction after each movement'of the carrier, thus placing the fulcra of the carriers in different positions at different strokes, as indicated by the dotted lines in Fig. 1. The slidebar h derives its movement from a cam-groove, m, in adisk, m', the said camgroove receiving a roller or other stud, mi, attached to the slide-bar. The cam-disk 'm' is attached to a shaft, m3, mounted in suitable bearing of the frame-work. The shaft mi has fast to it a gear, 24, which is engaged and rotated by agear, 25, secured to a bevelgear, mit, loose on a stud, (not shown,)the said bevelgcar being engaged and rotated by a bevel-gear, ma, fast on the shaft CZ. Each of the cam-disks 20 is secured tothe front end of Each picker-stick has at one side al a shaft, 2G, one of which is shown in Eig. 3, each of the said shafts having at its inner end a bevel-gear, as 28, (see Fig. 10,) which is engaged by'a bevel-gear, 29, on the shaft C?. Each carrier g at its rear end has a rollerstud, 30, which is embraced by the slotted up per end of the lever or picker-stick t or s2.

In Eig. 1 the holder d is shown as acting upon the shuttle s; but in Fig. 2 the holder is acting to hold the shuttle t. v

In accordance with my invention the broad reed has the spaces between its dents iilled with warp from the outer ends of the reed to a point near the intermediate shuttle-box, e, and the two carriers are moved in the same direction and in substantially the same time, the length of the back ward and forward stroke of each carrier being the saine; but by shifting the fulcra 17 of the picker-sticks or levers t s2, as described, theirstartiug and stopping points are shifted without altering their length of stroke. As the two carriers approach the intermediate shuttle box, one carrier is without a shuttle; but the carrier having the shuttle to ,be left in the said intermediate box abu'ts against and knocks out ofthe said box the shuttle then in it far enough to permit its spring -latch to fiy out and engage the socket of the carrier that approached the intermediate shuttle-box empty to receive a shuttle. As the carriers move outwardly from the intermediate shuttle box, one carrier takes with it a shuttle, ,the other carrier comes away empty, the carrier to come away empty being the one that last delivered its shuttle to the intermediate box. A shed is made in the warp at each side of the shuttle! box between each complete inward and ontward stroke of each carrier.

In factories for weaving wire-cloth it fre quently happens that orders are given for wire-eloth narrower than can be made on the regular looms, the looms being usually made for wide widths of wire fabric. In such cases the wide widths are cut longitudinally, leaving one selvage and one raw edge. This latter edge is objectionable to many, for the wire left at the raw edge has to be brought over to keep the woven Wire in place. tion these wide looms may be altered at but little expense to weave narrow goods. To make this alteration, Ihave but to supply the proper shuttles, place the intermediate shuttle-box at or near the center ofthe lay, and change what would be called the picking lnechanism for moving the carriers, in order that they may be reciproeated different disltances at alternate throws, to manipulate the shuttles,substantially as herein described, the holder being added to retain the shuttles in the intermediate boxes.

I have herein shown the holder as consisting of a block somewhat segmental in shape, I having found a holder ofthe shape shown suitable for the purposes intended; but I do not desire tolimit this my invention to a holder of the precise shape shown, for instead I may By my inven-I IOO IIO

employ any other equivalent device capable otholdiug the shuttle in like manner, it being understood that the chief object and purpose ofthe holder is to produce friction upon the shuttle aud retain it in the intermediate shuttleAboX at a point where it may be left by its carrier until the said shuttle is to be removed from the said intermediate shuttle-box.

I have herein shown and described mechanism for actuating carriers; but I desire it to be understood that instead of the mechanism so shown I may employ any other usual mechanism common to socalled positive loomsV17 to actuate the carrier or device for positively moving the shuttle into and from the shed.

I am aware that a patent describes a loom provided with acentral shuttle-box containing a double-ended picker which is actuated by a centrallylocated pickenstick; but the loom referred to docs not contain carriers to move the shuttles positively, nor does it contain a holder to retain the shuttle in the box until it is again to bc taken from the central shuttlebox.

1. The lay and its intermediate shuttle-box open at both ends, aholder, and two shuttles, combined with two carriers, and means to actuate them, substantially as described, whereby cach carrier at onemovemcnt ismade to place a shuttle in the intermediate shuttle-box and to take it from the said shuttlebox at its next movement, substantially as described.

2. The lay and an attached intermediate shuttle-box and a holder to actupon. the shuttle in the said box, the said shuttle-box having a curved surface, as at 7, and a shuttle having aspring-latch and a projection at one end, combined with a carrier having a sock- Veted head to embrace the said projection and to be engaged by the said springdatch.

3. The lay, two shuttles, an in termediate shuttle-box attached to the lay and open at both ends, and a shuttle-holder to retain the shuttles therein in the position where they may be left by the carriers, combined with tivo carriers, and with means to move thcm,\vhere by the shuttles Aattached to the carriers may bel made to abut, the one against and drive the other partially from the intermediate box, substantially as described.

4. The lay, its attached intermediate shuttle-box, two shuttles, and carriers to move the shuttles, as described, combined with the levers or pieker-sticl s, the sliding rod upon which they have their fulcra, and with means to move the said rod and to actuate the said levers or picker-sticks upon their fulcra, substantially as described, whereby the stroke of each carrier is alternately variedasto its start ing and stopping point, for the purposes set forth.
