SHUTTLE-GUARD FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 453,499, dated June 2, 1891.

Application filed January '7, 1888. Serial No. 260,069. (No model.)

To all 1071,0712 it may concern.-

Be it known that I, J AMES M. PECKHAM, of Fall River, county of Bristol, State of Massachusetts, have invented an Improvement in Shuttle-Guards for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention relates to a shuttle-guard to be used on a loom for preventing the shuttle from being accidentally thrown off from the shuttle-race.

The shuttle-guards now 00.11] monl y used consist of a wire or rod connected with the handrail or top bar of the lay, and the fastening of the sh Little-guard to said hand-rail is likely to injure the latter, especially if the fastening bolts or screws work loose in the bar of wood of which said hand-rail is composed.

The object of the present invention is to produce a shuttle-guard that is securely fastened in proper position with relation to the shuttle-race, and is so located as to be more eflicient in guiding the shuttle and preventing the accidental deflection thereof than the shuttle-guards now commonly used.

The invention consists,essentially, in a shuttle-guard composed of a rod or wire provided with eyes at each end that receive bolts or screws by which the said rod is securely connected with the shuttle-box or mouth of the guide, into and from which the shuttle is thrown, the said rod being provided with an offset near one end in order not to interfere with the operation of the stopping device controlled by the filling-thread.

Figure 1 is a front elevation of a portion of the lay of a loom provided with a shuttleguard embodying this invention; Figs. 2 and 3, a front elevation and plan view respect ively, of portions of the shuttle-guard detaehed; Fig. 4:, an end elevation showing the positions of the lay and breast-beam of the loom, and Fig. 5 a plan view of a portion of the parts shown in Fig. 4.

The shuttle-guard a forming the subject of this invention consists of a rod or wire of proper length to extend from one to the other of the mouth-pieces Z at the ends of the shuttle race 0, into and out from which the shuttle is thrown in the usual manner, the said mouth-pieces I) being usually composed of cast-iron.

The rod or bar a isprovided at each end with eyes a (see Fig. 2) to receive bolts or screws by which the said rod is fastened to the said mouth-pieces I), as shown at b in Fig. l, the said fastening being permanent and durable, owing to the durable nature of the material of said mouth-pieces.

In order to provide for the properoperation of the weft-fork (l, forming a portion of the usual weft-thread stop-motion device, the rod a is offset near one end, as shown at (0 and thus accommodates the rising and falling movement of the end of the latch-lever d that takes place at the end of the beating-up movement of the lay.

The weft-fork (Z forms a portion of a well known stop-motion device, its hook end (1' cooperating with a part that controls the belt or clutch shipper by which the loom is stopped and started, and causing the said loom to be stopped if said lever remains in the position shown in full lines, Fig. l, when the pick of thread is beaten up by the lay. The other end of the fork is provided with a number of projections (Z which are so arranged as to receive between them a number of projections e on the lay when the latter arrives at its extreme forward movement in beating up the filling-thread. The said projections c are commonly called the grid, and when the fillingthread is intact, as indicated at f, Fig. 4:, it is interposed between the projections e and projections (1 so that the former, instead of entering between the projections (l press the filling-thread against the said projections, and thus tip up the fork, as indicated in dotted lines, .Fig. 4, so that it does not act to stop the loom. If, however, the filling-thread breaks, so that it is not interposed between the projections e and the projections (Z the former pass between the latter and the lever is not raised, and the loom is consequently stopped. The offset a of the shuttle-guard passes wholly over the end of the fork d at the moment that it is raised by the action of the projections e and thread f, as indicated in dotted lines, Fig. 5. The shuttle-guard a by this construction may be placed very close to the shuttle-race,

and will assist in guiding the shuttle across ing an offset near one end, substantially as the race and effectually prevents the shuttle and for the purpose described.

from being thrown off from the shuttle-race. In testimony whereof I have signed my It will not cause wear or injury to any part name to this specification in the presence of 5 of the loom, as is sometimes the case when the two subscribing Witnesses.
