Abstract
565,459. Clockwork winding mechanism. LANDIS & GYR SOC. ANON. May 11, 1944, No. 8976. Convention date, May 17, 1943. Addition to 565,316. [Class 139] In a winding arrangement in which a switch in the circuit of the electric motor is controlled by a nut travelling on the driven shaft of the spring motor, a safety device is provided by disposing one of the gears of the driving train between the motors so as to be clamped by the nut and so stop the electric motor on the failure of the switch. The spring drum 4 is driven from the electric motor 25 through a train 19, 20, the gear 22 on the shaft 19 being so disposed as to be clamped between the travelling nut 8 and the driven gear 5 of the spring motor 4.
