Abstract

622,248. Change-speed gear. JUY, L. C. H. Oct. 23, 1946, No. 31512. Convention date, April 4, 1944. [Class 80 (ii)] In a change speed gear where change of ratio is effected by lateral displacement of a chain on nested sprockets, the guiding rollers 2, 3 are mounted'between a single plate 1, which may be the tensioning arm, and plates 4, 5 independently mounted on the plate 1 and spaced apart. Specification 459,483 is referred to.
