- the take-up and let-off mechanisms if allowed to operate until the lay comes to rest will therefore advance the warps a short distance without any filling, and it becomes difficult on starting the loom again to lay the next weft-thread close up to the one which was last beat in.

SPECIFICATION forming part of Letters Patent No. 615,635, dated December 6, 1898.
Application iled February 14, 1898. Serial No. 670,176. (No model.)
a perspective view showing sufficient of a loom to illustrate the construction and application of my invention. Fig. 2 represents a partial end view with the parts in another position. Fig. 3 represents a View of the other end of the loom. Fig. 4. represents a partial front elevation and section. Fig. 5 represents a detail vertical section taken through a portion of the shipper-lever.
The same reference characters indicate the same parts in all the figures. I
In the embodiment of my invention hereinafter described I employ in connection with the usual stop-motion knock-off a series of devices whereby the take-up and let-off mech-` anisms are automatically stopped when the shipper-lever is knocked off and are held from action until said shipper-lever is again placedin the keeper-notch. NVhen the shipper is knocked off by reason of the filling running out or breaking, the loom usually runs for a short time before coming to a full stop because of the momentum acquired by its parts. The take-up and let-off mechanisms if allowed to operate until the lay comes to rest will therefore advance the warps a short distance without any filling, and it becomes difficult on starting the loom again to lay the next weft-thread close up to the one which was last beat in. It is therefore desirable to stop' both the take-up and letoff mechanisms the instant the shipper is knocked off in order to prevent the advance of the warps and also to maintain them at their proper tension.v The object of my invention is to furnish an improved mechanism for accomplishing this result.
Referring to the drawings, a is the frame of the loom, b the lay, b b' the lay-swords, c the breast-beam, CZ the warp-beam, @the whiproll, f the crank-shaf t, carrying the eccentric f', which operates the take-up pawl g, h the take-up ratchet, and t the slack-pawl, all of which parts are of familiar construction and need no extended description. Parts of the usual let-off mechanism are also here shown, including the pinion j, worm j', ratchet 7c on the worm-shaft, rocker-arm m, carrying pawl m', and rod n,connected to rocker-arm and operated by the beat-lever o. y I also show parts of the usual weft stop-motion, including the feeler or hammer p, operated by cam p', slide q, carrying weft or lling fork q', stop-motion rod or rock-shaft r, connected with slide by means of lever q2 and carrying at its end an arm r', which engages the take-up pawl g, and shipper-lever s.
r2 is a knock-off lever carried at the end of the rod r and formed with a lug r3, which engages the shipper-lever s. I/Vhen the filling breaks and the hook on the filling-fork q is engaged by the feeler p, so as to move the slide q' and rock the rod r, the knock-off lever r2 engages the shipper-lever and dislodges it from its keeper-notch s', thus causing the belt to be shifted and the loom stopped in the wellknown manner.
tis a catch-lever consisting of a hub portion 2 and an end portion 3, adjustably secured together, the said lever being pivoted to a stud t' on the frame of the loom and connected with a spring i2, which tends to elevate its forward end. The knock-off lever r2 is formed with a lug r4, which normally rests on the upper edge of the catch-lever, but which enters a notch t5 in said lever when the shipper-lever is knocked off, as shown in Fig. l.
The positions occupied by the parts before the shipper is knocked off are shown in Fig. 2. If-the lay on its forward stroke fails to lift the heel or hook of the filling-fork, the shipper will be knocked off on the next forward stroke of the fecler p, and the notch t3 in the catch-lever will engage the lug r4 on the knock-off lever and will hold the latter in its abnormal position, as shown in Fig. l. The take-up pawl g is at the same time lifted by IOO eaess the arm r4 out of engagement with the ratchet 7L and is held in this position so long as the lug r4 is engaged by the notch 3.
h2 is a sword-hook secured to the righthand lay-sword ZJ'. This sword-hook does not itself engage the beat-lever o, as is usually the case, but carries a detent Z13, which is arranged to be thrown into and out of position to engage said lever. The detent b3 is formed as a bell-crank lever and is pivoted to a downward extension 4 of the sword-hook bi. Its lower inwardly-extending arm is preferably weighted and is connected by a wire u with the end of an arm 1'5, attached to the stopmotion rod r. Normally the detent b3 lies up against the sword-hook b2, as shown in Fig. 4, so that a tongue 5, formed on its upperend, stands in a position to engage the lower end of the beatlever o. Then when the lay is rocked the beat-lever is engaged in each stroke and the let-off mechanism actuated in the usual manner. lVhen the shipper is knocked ott, however, the arm 75 is raised and the detent b3 moved outwardly ont of position to engage the beat-lever. The let-off mechanism is thereby rendered inoperative, and is so maintained as long as the catch-lever z5 holds the knock-olf lever in its abnormal position. (Shown in Fig. l.)
In addition to the foregoing I provide means for returning the part-s automatically to their normal operative positions when the shipperlever is placed in its keeper-notch to start the loom. Said means may comprise the following constructions: s2 is a pivoted cam member or detent mounted in a bracket or collar S3, secured to the shipper-lever s and arranged to bear against a complementary cam member or lng t4, attached to the catch-lever t. The detent s2 is arranged to engage a portion of the bracket s3 and to be rigidly held in a vertical position, as shown in Fig. 5, when pressure is applied to its lower end in the direction of the shipper-lever. WVhen pressure is applied in the opposite direction, the detent turns on its pivot and tends to assume the horizontal position shown in dotted lines. Assuming the parts to be in the position shown in Fig. l, it will readily be seen that when the shipper lever is moved to place it in the keeper-notch s the detent s2 moves against the cam-lug t4 and depresses the catch-lever to which said lug is attached, thereby disengaging the notch 3 from the lug r4 and allowing the knock-off lever and the parts connected with and under the control of the stop-motion rod r to assume their normal positions. lVhen the shipper-lever reaches the keepernotch, the detent s2 passes over the inner edge of the catch-lever i and locates between said lever and the frame-casting of the loom, thus giving the lever room for free upward movement. When the shipper-leveris knocked ott, the detent s2 yields in passing over the edge of the catch-lever.
To those familiar with the art the advantages of my improvement will be apparent. Since the let-oft and take-np mechanisms are positively held out of action, the lay may be moved back and forth by hand as many times as desired without moving the warp or the cloth. In the particular construction which I have shown as illustrating my invention the parts may be so related that the shipper-lever can be moved a considerable distance inward toward the keeper-notch from the position shown in Fig. l without releasing the knockotf lever r2 from its engagement by the catchlever t, thus enabling the operator to shift the belt onto the driving-pulley (or to actuate a clutch mechanism) to an extent sufficient to drive the lay without moving the take-up or let-off mechanisms. This will be appreciated as a time and labor saving improvement. The belt-shifting or clutch-operating mechanism connected with the shipperlever s may be of any approved construction, and being well known in its operation is not illustrated in the drawings and needs no dcscription.
