Abstract
659,609. Variable-speed gearing. CAMILLIS, L. Sept. 30, 1949, No. 25099. [Class 80(ii)] In chain-shifting mechanism for cycles comprising jockey and tension pulleys g, h carried by a plate f supported on an axle c carried by an arm d secured at its upper end by a stud e to a gapped bracket b secured to the frame, the stud is adjustably held in the bracket b by a nut m and is threaded in the arm d, so that the latter can be swung from the full-line operative position shown in Fig. 1 to the dotted line position in which removal of the cycle wheel is facilitated, the arm being firmly held by friction in either position.
