Abstract
199,465. Karasek, W. C. March 22, 1922. Lift cages and doors, locking and unlocking and operating.-In locks fot well doors a fixed beak G on the door is engaged by a catch D releasable by a solenoid B. The circuit containing the solenoid is completed (1) by moving the lift controller to stop the lift thus de-energizing the coil N and allowing the contact plate fixed to its core to fall to the position shown, (2) by a cam switch in the motor room driven by the winding drum, there being a switch for each floor and (3) by turning the handle I to raise the movable beak F until it has brought an insulated contact plate T on a pivoted arm H into contact with the terminals K, J If the cam switches are dispensed with, the locking device may be fitted to the cage door which can then be opened whenever the lift is stationary.
