Abstract

1,017,780. Positive clutches. A. V. L. C DEBRIE. Sept. 12, 1962 [Oct. 31, 1961] No. 34839/62. Heading F2C. [Also in Divisions G2-G3] A positive clutch for engaging a pinion 39 with a drive-shaft 11 comprises a spring-loaded lever 41 pivoted within shaft 11 which it drives by engaging grooves 40 inside pinion 39 freely slidable on shaft 11 and permanently coupled to a driving shaft.
