Abstract

495,423. Change-speed gearing. SCHAERER, O. May 20, 1937, No. 14082. Convention date, May 23, 1936. [Class 80 (ii)] [Also in Group XXII] A speed changing and reversing gearing comprises a longitudinally movable and rockable support 50, Fig. 2, carrying two coupling gear-wheels 53a, 53b, the former of which is in direct engagement with a driving wheel 55 carried by the support and the latter of which is in gearing connection with the driving wheel 55 through the intermediary of an idle wheel 54. The rocking support is adapted to be moved by means of handle members 47, 51 to bring the coupling wheels selectively into engagement with any wheel of a stepped cone 52 on the driven shaft 58.
