Abstract

522,970. Controlling change-speed gearing. PESCARA, R. P. Dec. 21, 1938, No. 37208. Convention date, Nov. 26. [Class 80 (ii)] Change-speed gear with preselector means is provided with means for modifying the constitution of the group or groups subjected to preselection in addition to the group preselection means. The means for modifying the constitution of the group is operated in accordance with the speed of a vehicle. The subject-matter is wholly described in Specification 522,969 in connection with Figs. 5, 6 (Cancelled).
