    Abstract: 1,189,950. Control of motors. VAPOR CORP. 27 Sept., 1968 [6 Nov., 1967], No. 46004/68. Heading H2J. [Also in Division E2] In an electric door operator having an output shaft 14 rotatable between open and closed positions of the door, control of the door movement is effected via a cam 43 secured to and rotatable with the shaft and which co-operates with three fixed switches 40, 41 and 42, there additionally being a locking device 24 operable independently of the shaft and which includes a lock releasing solenoid 34. As disclosed, the door motor and solenoid are energized manually to initiate opening, and switch 40 operates at the end of the opening cycle to de-energize the motor, switch 41 operating before this to actuate a door opening cushioning circuit and to deenergize the solenoid. Switch 42 operates near the end of the closing cycle which is initiated manually to de-energize the motor and to actuate a door closing cushioning circuit. Cushioning is effected by adding a resistance to the motor circuit.
