At the outer end of the rock-shaft e, is a second crank-arm f, to which is adjustably connected the upper end of a rod 9, which, at its lower end, passes through an erture in an arm h, rigidly fastened to t e front portion of the link lever 18. The rod 9, is yieldingly connected with the arm It, by means ofa springz', which bears at its lower end upon the arm k, and at its outer end against a collar 7', fast on the rod g." Nuts Z, adjustably. screwed "to the lower end of the rod 9, beneath the arm h, maintain the rod g,'in proper relation to the arm h. It is evident that when the forward end of the lifting lever 18, is raised for the purpose of lifting the shuttle-- box (and hence gettinga fresh weft-carrier) the rods 9, and 0, are likewise lifted, thereby 80 causing the -jaw' 12, to swing downwardly past the jaw a, thereby severing any thread which may then be between the jaws. The timing of the change-shaft D, is such that it rocks when the shuttle containing the de- 85 pleted weft-carrier is in the shuttle-box C, ' at the replenishing side of the loom, in accordance with the usual timing in weft-replenishing looms. Therefore the thread extending from the selvage at the replenishing 40 side of the loom to the nearly depleted weftcarrier within the shuttle K, extends behind the aws. This strand of weft is guided and directed to and between the jaws before. the pivoted to jaw closes by means of the thread director F. This thread director F. as best shown in Fig. 3, is an arm depending from a horizontal rock-shaft l1, carried by the lay near the entrance to the shuttle-box C. The thread-director F, ordinarily is located behind the reed M, as shown in Fig. 4, "with; its lower free end immediately above the plane oi the race-plate N. of the lay. The upper surface of the lay is recessed at m, to permit the -Forward swing of the lower hooked end n. of the tlil'(:l(l-(ll1'00lj0i, F. Ac- 1 cordinpjly, when the dircclorlflis swung forwardly, its lower hooked end travels for? wardly in the lay recess m, first below the 60 plane of the weft-lhrczul, thereby taking hold of the weft-thread and then carrying it forward and above said recess and between the jaws of the cutter, as shown in Fig. 5. This thread-(llrooting movement of M th thread-director F, occurs before the the race-way oi the lay; a thread-director meagre pivoted jaw 15 closes, so that the threadg is certainly 'cut. 1 begins to close substantially as soon as the st; thread-director F, begins its forward swing, but the thread-director F, is given suiiicient surplus swing, as indicated in Fig. 5, so that it can carry the thread between the jaws while. they are still apart and before the 35 pivoted jaw b, closes down. The thread-cutter is located above" the plane of the lay so that the lay passesbeneath the cutter, and the thread director on the lay directs the thread in o the path. of, the cutter while the shuttle with the depleted weft which is to be cut is in the neighboring shuttle box. The surplus swing of the thread direcim' -F carries it forward of the cutting jaws, as shown in Fig. 5. As the thread at this time extends from the salvage of the cloth to the shuttle, this extent of swing' of the thread director tightens the thread so that it is held taut when the cutter acts, thus'insuring the 10p cutting of the thread. As the shuttle-box descends a torsional. spring Q, restores the thread-direotor to its normal rearward position of rest, and the pivoted jaw of the cutter opens. H95 A spring .T, permits the entire cutter to slide forward in case of any obstruction as, for example, in case the shuttle fails to properly box in the shuttle-box C. I claim 1. A weft-replenishing" loom wherein the replenishment occurs prior to the complete exhaustion'of the running! weft having, in combination, a rising and falling shuttle 1 7 box at the replenishing side of the loom; 211 change-shaft which is rocked when the run-f nmg weft approaches exhaustion; a train 'of mechanism operatively located between the change-shaft and the shuttle-box, where-- by the shuttle-box is lifted for the purpose of obtaining a fresh supply of weft and for, ejection of the depleted weft-carrier; a thread-cutter having: a stationary jaw and a pivoted jaw; instrumentalities between said pivoted jaw and the train of mechanism which lifts the shuttle-box, whereby the pivoted jaw is closed upon the stationary jaw concurrently .with the lifting of the shuttle-box; the lay having recess below normally located back of the reed and having a hook at its loWer end which swings forwardly first-through and then above and in front of said recess when the thread-director is actuated; a rock-shaft carried by the lay which carries said thread-director, said rock-shaft having a crank-arm; and a tappet on the rising and falling shuttle-box which encounters said crank arm when the shuttle-box rises, whereby the thread-director is swung forward to catch the weft and deliver it between the jaws of the cutter. 2.
