REVERSING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 491,776, dated February 14, 1893.

Application filed October 20.1892. Serial No. 449.478. (No model.)

To all whom it may conccrn: shaft 2, and provided with a friction face Be it known that I, GEORGE E. HUTOHINS, and driven by a belt 6, in this instance belted a citizen of the United States, residing at from above.

5 is a friction driving pulley loose on the or to any other fixed part of the loom frame,

and serves to keep the end 18 of the lever 16 in its lowest position, as shownin Fig. 1.

The operation of my supplemental mechanism will be readily understood by those skilled in the art. When the loom is stopped pulley 5, or with the pulley itself, in case it is belted from below, and also bring the pulley 26 in contact with the friction pulley 7 fast on the shaft2. The revolution of the pulley 5, which runs loose on the shaft 2, will cause the pulley 22 to revolve, and through the gears 23 and 24, the pulley 26 will transfer the power to friction pulley 7, and-will cause said pulley to revolve, and also the shaft 2 on which said pulley is fast, thus reversing the loom and moving back the lay, into the position shown by dotted lines, Fig. 1. The releasing of the lever 16 allows the spring 27 to act to disengage the pulleys 22 and 26 from the pulleys 5 and 7, and leave the lay in its backward position, so that the attendant may remove the shuttles from the shed, or repair the warp, preparatory to re-starting the loom in the ordinary way. By using a small pinion 23 and a larger gear 24, I-reduce the motion of the pulley 26, and prevent the too sudden reversing of the loom, and the too quick return of the lay.

The advantages of my improvement will be readily appreciated by those skilled in the art.

My supplemental attachment is of very simple construction and operation, and is adapted to be combined with looms of ordinary construction without any change, and requires but slight power to operate.

The details of construction of my supplemental mechanism maybe changed if desired; the lever 16 may be adapted to be operated by hand if desired, and the pulley 22 may extend under and engage the edge of the flange on the loose pulley 5, instead of the belt, and thus prevent any damage or injury to the belt by the friction of the pulley.

Having thus described my invention, what Iclaim as new and desire to secure by Letters Patent is:

1. In a loom, the combination with the belt pulley loose on the driving shaft, and the friction pulley fast on said shaft, and the gearing for operating the loom, of a supplemental mechanism for reversing the 100111 by power to move back the lay, consisting of a pivoted lever supporting a pivoted yoke carrying a pulley adapted to engage the belt pulley, and a second pulley adapted to engage the friction pulley,and intermediate gearing between the pulleys supported in said yoke, substantially as set forth.

2. In a loom, the combination with the belt pulley loose on the driving shaft, and the friction pulley fast on said shaft, of means for conveying power from the belt pulley to the friction pulley, to reverse the 100m byv power and move back the lay, consisting of a lever pivoted at one end of the loom, with its front end adapted to be engaged and operated from the front of the loom, and its rear end adapted to extend under the belt pulley and friction pulley, and provided with a pivoted yoke carrying two shafts, and a pulley mounted on each of said shafts, and intervening gearing between the shafts, for the purpose stated, substantially as set forth.

GEORGE F. HUTCHINS.
