Abstract

278,852. Stuchbery, A. L., and Turner, J. E. Sept. 2, 1926. Variable-speed gearing comprises an epicyclic train T controlled by a slipping clutch or brake having balls D between conical surfaces E, C. The balls D are free to move in an endless helical groove in the male cone C and are pressed by a spring J against spiral undulations within the female cone E, the undulations not conforming to the helical groove. By clutching and holding fast the drum E alternately, driving in two directions may be obtained.
