Abstract

961,520. Eccentrics. DURKOPPWERKE A.G. March 7, 1963 [March 26, 1962], No. 9053/63. Heading F2K. [Also in Division D1] An eccentric sheave 38 is anchored to a rotary shaft 13 by a pin 381 slidable transversely in the latter. Sheave 38 is engaged internally by an offset portion of a sleeve 36 slidably mounted on shaft 13. An annular groove in sleeve 36 is engaged by opposed bosses on one arm of a twoarmed lever 43, the other arm of which is connected by a linkage to a treadle. Actuation of the latter thereby serves to shift sleeve 36 axially against the bias of a spring 53 for varying the eccentricity of sheave 38.
