Abstract

588,000. Mechanism for ensuring unidirectional rotation. CHAMBERLAIN - & HOOKHAM, Ltd., JAMES, S., and DEACON, L. O. Jan. 8, 1945; No. 661. [Class 80 (iv)] A device for permitting rotation of a synchronous electric motor only in the desired direction comprises a pivoted double-armed pawl c biassed by a spring d against either of two stops e, and a wheel b driven from the motor and carrying a peg a. On starting the motor, with the pawl positioned as shown, the wheel b may rotate in the clockwise direction, the pawl c being moved idly against spring d when the peg a engages the inclined surface of the pawl. If the motor starts in the wrong direction however the peg a engages a shoulder f on the pawl, rebounds, and rotates in the correct direction. By biassing pawl c against the other stop e, anticlockwise rotation is permitted but not clockwise. Various modifications are described.
