Abstract
223,882. Elevator Supplies Co., Inc., (Assignees of Weeks, W. W.). Oct. 22, 1923, [Convention date]. Operating and controlling doors, gates and barriers by springs; checks.-In lift and like doors actuated by toggle-lever mechanism to which checking means is connected, the check is combined with a switch which opens the circuit of the hoisting motor when the door is opened. The toggle-lever mechanism is connected to the rod 14 of a plunger 16 working in a cylinder 4 containing oil which is attached to a larger cylinder 2 containing a compression spring 24. A spring-retaining member 12 secured to the rod 14 is attached to a ring 48, Fig. 2, of insulating material in which is mounted a pair of pins 50 attached to a conducting ring 46. Springs 54 maintain the ring 46 in contact with the enlarged heads 42 of terminals 26 until the door has been sufficiently opened for the shoulders 51 to engage the heads 55 of the pins 50.
