SPECIFICATION forming part of Letters Patent No. 561,841, dated June 9, 1896.

Application filed October 2l, 1895. Serial No. 566,390. (No model.)

To @ZZ wiz/0m, it may concern.-

Be it known that I, WILLIAM WEAVER, Aa citizen of the United States, residing at Norwalk, in the county of Fairfield and State of Connecticut, have invented certain'new and useful Improvements in Looms, of which the following is a specification.

My invention relates tor looms in which two or more ,shuttles maybe used for simultaneously weaving two or.more fabrics or conipoundjpor double-faced fabrics; and my invention consists in means whereby to secure races' for 4theshuttles while permitting any of the threads of the warp to be shifted to any' desired position and across the` shuttle race or races, as fullylsetforth hereinafter, ,and as illustrated in the accompanying drawings, in which- Figure 'l is a diagram illustrating my improvenient` and its operation in connection with the lathe and showing the dierent positions of the warp-thread. Figs. 2 to i illustrate the means adopted for insuring a close selvage. Fig. 5 is a perspective view illustrating the face of the lower shuttle-race. Fig. G is an enlarged elevation of the lathe. Fig. 7 is an elevation in part section showing the means of securing a movable shuttle-race. Fig. S is a side view'of the loom with my iin,- provements. Fig. 9 is a sectional elevation, in longitudinal section, of said loom.

Before describin gin detail the construction of my improved loom l refer to the diagram, Fig. l, which illustrates the principal feature in connection with a double race. In this diagram, -Avis the lathe, provided with the usual reed l and usual race 5c, across which the shuttleA is thrown by the picker inthe ordinary manner. There is, however, an additional race fJ for another shuttle 2, and this additional race consists of a series of 'fingers e in the shape of rods or blades parallel to each other. These are preferably so supported that they may be thrown out of the way to beat up the weft and then into position parallel to the lower race fr, and sufficiently close together to constitute a way for the shuttle 2 as it is thrown across the lathe, and so also as not to interfere with the movements of the warp-thread to the different positions shown in Fig. l. To permit such warpthread movements, a preferable support consists in forming each blade or rod et at right angles to an arm 5, extending from a rockshaft 6, turning in bearings on the lathe, so that the warp-threads may pass up between the arms 5 and pass the blades 4. As a result any or all of the warp-threads may pass from the position a to either the position h or c, or from the position c to either the position h or a, or from the position h to either of the positions a or c. Therefore there is combined with a single reed two shuttle-races and two shuttles, one of the races consisting of parallel separate blades capable of being moved into position when the shuttle is to be thrown and to be moved out of position when the reed beats up against the fabric, and it is possible, therefore, to weave two Afabrics parallel to each other with the different warps passing through a single reed, or to weave a single fabric having opposite faces of entirely different characters or patterns.

Inas much as the lathe cannot beat4 up against the fabric until the shuttle has passed across the warp, the shuttle-thread would be apt to take the position illustrated in Fig. 2,

so ,that when beaten up it would form a loop at the selvage, as shown at 1;. To prevent this, I prefer to arrange what l shall hereinafter term the movable race-blades in sections, so that those at one edge or side may be thrown out after the passage of the shuttle while the latter is moving over the raceblades at the opposite edge. Thus, as shown in Fig. 3, the race-blades are in two sections '1J ZJ', capable of swinging independently, (although there might be an intermediate section,) so thatwhen the shuttle has passed one section-fas, for instance, the section PT1-thc latter may be swung outward to permit the shuttle-thread to be drawn close to the selvage while the shuttle still travels upon the other section, h', after which the latter section is swung out to permit the shuttle-thread to 9 be beaten up. Of course the lower shuttle upon the usual race will draw its thread close to the selvage in the ordinary manner.

In order to permit fabrics of different widths to be woven in the same loom, l provide means IOO whereby the length of the movable race may be varied. Thus, as shown in Figs. 7 and 8, the different race-blades nearest the sides of the loom may be upon sleeves 10 upon the rockshaft, the innermost sleeve provided with a set-screw 12 for binding it to the shaft and all the sleeves having coinciding ears 13 with coinciding openings and a stationary sleeve 14: on the frame having an ear 15. By loosenin g the screw V12 and passing ybolts through the openings of all the coinciding sleeves 10 and of the ear 15 of the stationary sleeve 14 and the ear of the adjacent sleeve 10 all of said sleeves and their movable race-blades will be bound together stationary and will constitute simply a part of the stationary race beyond the edge v of the fabric. Vhen a wider fabric is required the screw 12 is turned to bind its sleeve 10 to the rock-shaft and the boltis removed connecting any two adjacent sleeves when those at one side of the sleeves thus disconnected will rock with the shaft, while those at the opposite side will remain stationary.

It will be seen that the blades 4 prevent any wear of the warps occupying the position ZJ, Fig. 1, as said warps lie between the said blades, and I may secure the same result upon the lower race x by providing it with parallel ribs 1G, Fig. 5, between which the war-ps in the position c, Fig. 1, will lie. The ribs 16, instead of being fixed upon the lower race, may consist of fingers 1Ga upon arms 5% cX- tending' from the rock-shaft and .longer than the arms 5, as illustrated in Figs. G, 7, and 9 of the drawings.

The lathe, with its boxes, pickers, reed, and movable raceor races, may be constructed in different ways and combined with different operating devices, and I will now describe a construction which I have found effective as embodiedl inwerking mechanism.

Referring especially to Figs. 6 to 9, B is the frame of the loom, to which is pivoted the lathe A, carrying the reed 1', having two shuttleboXes w 'w' at each end of the shuttles 2 8 and provided with a rock-shaft inltwo sections 6 G, carrying the movable race-blades, as before described. There are two picker-sticks C D and pickeroperatin g levers E connected therewith and actuated by bowls 1S on the cam-shaft 1.9,the partsbeing so adj usted, however, that the picker-sticks will be brought toward each other simultaneously,` and each stick is provided with two pickers, one cx tending into each of the shuttle-boxes, so that the shuttles are thrown simultaneously from the opposite ends of theraces.

Any suitable Jacquard mechanism Z is arranged to operate the harness E', as desired, to properly open and close the warp to shift the threads to make a single double-faced fabric, or, as arranged as shown in Figs. 8 and 9, to simultaneously weave two fabrics, the warp being delivered from and the fabrics taken upby suitable beams, as usual.

In order to lift the movable race after the 18, connected by a connecting-rod 19"FL with a lever 20, having a bowl 21, which enters the slot of a cam 22 on the shaft 1,9, the said cam being of such construction as to vibrate the lever in time to lift and depress the movable race-blades in the following manner: It sometimes becomes necessary to lift the blades in order to get access to the warp when the ma* chine is not running, and Itherefore provide means for locking the rock-shaft or its sections to and for disconnecting or unlocking them from the arm or arms 18. Thus the lever 23, fixedly secured to the rock-shaft, carries aspring-bolt24, the end of which is adapt ed to notches in the hub of the arm 18, and by drawing out said bolt the rock-shaft may beturned independently of the said arm.

It will be evident when, as before described, there is more than one movable race -as, for instance, two, as would result from using the two sets` of arms and blades: 16M-the action of the jacquard will be modified accordingly, and each staff will have, of course, a pick for each shuttle.

It is sometimes desirable to operate the loom ICQ so quickly that the throwing down of the mov ff able shuttle-race blades would cause them to make contact with the fabric, or the upper fabric when there are two fabrics occupying its normal position. In order to avoid this, I provide for depressing the fabric as the lathe moves back after-beating up the thread, so as to permit the movable shuttle-race blades to swing inward without Contact with the fabric. Thus, as shown in Fig. 9, I make use of a cross-roll 30, which is depressed as the lathe begins to move back and theblades begin to descend. This depressingmay be effected in any suitable way. As shown, the roll 30 is carried by two arms 31, and is connected by a rod 32 with a lever 33, which is depressed at each backward movement by a projection 35 on the cam 34 on the shaft 19.

Vithout limiting myself to the precise construction and arrangement of parts shown and described, I claim as my invention- 1. The combination in a loom, of the lathe, a movable race consisting of a series of parallel blades supportedv movably upon the lathe, and means for shifting the same, and a roll` 30 bearing upon the fabric, and means for depressing the roll to carry the fabric out of the way of the-blades, substantially as set forth.

2. In a loom the combination with the lathe provided at each end with two shuttle-boxes, of suitable shuttle-actuating means, a shuttlerace consisting of blades or bars supported in sections, means for automatically, posi- IIO tively and successively moving the sections into and out of position between opposite slinttle-boxes substantially in the manner hereinbefore set forth and means for fully opening the warp to either or both shuttleraces, substantially as described.

3. In aloom, the combination with the lathe provided at each end with two shn ttle-boxes, of suitable shu ttle-actuating means, a sh uttlerace between the shntt1eboxes, consisting of stationary sections and intermediate movable sections each of which is formed of blad es or bars, and means for automatically and positively moving the movable sections, substantially as described.

et. In a loom, the combination with the lathe provided at each end with two shuttle-boxes, suitable shuttle-actuating means, a shuttlerace between the shuttle-boxes consisting of stationary sections and intermediate movable sections each of which is formed of blades or bars, means for connecting one or more of the stationary sections to the movable sections and means for automatically and positively nioving the movable sections, substantially as described.

5. In aloom the combination with the lathe provided at each end with two shuttle-boxes, suitable shuttle-actuating means, a double shuttle-race between the shuttle-boxes, consisting of parallel blades or bars provided with two series of iingers in different planes, the fingers of the upper series constitutinga support for the upper shuttle, and those of the lower series forming a support for the lower shuttle, substantially as described.

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