Abstract

637,217. Variable-speed gearing. LIVERMORE, W. T. July 6, 1945, No. 8522/48. Divided out of 637,158. Drawings to Specification. [Class 80 (ii)] The subject-matter is the same as Specification 637,158 but the claims are directed towards the automatic control of the friction clutches to provide a different rate of application during downshifts than during upshifts to allow for, and prevent respectively, speeding-up of the engine so as to obtain a smooth change. Specification 515,001 also is referred to.
