Description:

Claim:

This invention relates to an improvement in variable-speed devices, for which Letters Patent No. 204,585, dated June 4, 1878, were granted to me; and it consists, essentially, of a series of change-gears, substantially as set forth in my said patent, and a corresponding series of clutches arranged in connection with a hand-lever or other suitable device mounted upon stationary supports, so that the attendant can, without stopping the machinery, shift said clutches, and thereby vary the speed of the driven member at will.
