The details of theabove device may be moditied in various ways without departing from the main feature of the invention. For instance, the rod h may be connected directly to the lever G, and the spindle of the. wheel F may be acted upon by a strap and weight instead of by a spring, or a coiled spring may act directly upon the spindle without the intervention of a strap; and in. some cases the pin w may act directly upon a lug or'projection on the rod it, instead of through the medium of the-arm K, and where I may allude to the arm K the latter term is to be understood as including any equivalent device whereby the movement of the pin to can be transmitted to the unclutching-gear. Other means than those described may also be employed for gearing the wheel F to the shaft A, bevel-gearing being used instead of the worm and worm-wheel, for instance, and in some machines such a relation.of the wheel F to the shaft A may be permissible that said wheel may be geared directly to the shaft.

As shown in the drawings,theshaftA forms one of a number of feed-rolls, and the device is intended for use in connection with a spinhing-mule or other piece of machinery in which such feed-rolls are employed; but it may be used in connection with any shaft as a stopmotion device therefor.

4. The combination of the shaftA, the wheel F and its pin it, the arm K, means for moving the wheel F into and out of gear with the shaft A, a spring for retracting the wheel, and a stop-pin, ac, as set forth.

5. The combination of the shaft A, the shaft E and its worm a, the worm-wheel F and its pin to, the arm K, the lever G, to which the wheel F is hung, and means, substantially as described, whereby the said lever is actuated so as to carry the wheel into and out of gear with the worm, and whereby the wheel is retracted when out of gear, as set forth. o
