Abstract
169,772. Barker & Sons, Ltd., J., and Saxton, J. June 24, 1920. Lift cages and doors, locking and unlocking.- 'The well gate of a lift is locked, when the cage is not opposite the gate, by a sliding spring-pressed pin 5 which engages a hole 7 in a tongue 2 on the gate and is released when the cage strikes a button 14 carried by an extension 3 of the pin. When the gate is closed, as shown, the tongue presses against a plate 15 on a spring-pressed rod 8 and causes an insulated metal ring 11 to close the control circuit 17. On the opening of the gate, the spring 13 forces the plate 15 and rod 8 to the right and breaks the circuit, so that the cage cannot be operated until the gate is closed. The mechanism is enclosed in a casing 1 built into the well of the lift.
