Abstract
223,881. Elevator Supplies Co., Inc., (Assignees of Weeks, W. W.). Oct. 25, 1923, [Convention date]. Pneumatic actuation; sparking, preventing.-In lift doors actuated pneumatically, the actuating mechanism contains a switch which opens the circuit of the hoisting motor when the door is opened, and currents of compressed air aredirected across the switch terminals to reducearcing. The door is attached to the rod 6 of a. plunger 8 working in a cylinder 10 containing oil which is attached to a larger cylinder 2 containing a compression spring. A passage 22 controlled by a screw 26 connects the bottom of the cylinder 10 with a part 28 of greater diameter which is connected by a passage 30 to an oil reservoir 20. A spring-retaining member and piston 4 attached to the rod 6 is attached to a. ring 52 of insulating material in which a.re mounted pins 54, 56 attached to a conducting ring 50. Springs 62, 64 maintain the ring 50 in contact with the enlarged heads of terminals 36, 38 until the door has been opened sufficiently for the shoulders on the passages in the ring 52 to engage the heads of the pins 54, 56. The door is opened by admitting compressed air through the pipe 66 to the space below the piston 4. The air issuing from the apertures 70, 72, Fig. 3, in the end of the pipe 66 passes over the terminals 36, 38 and decreases arcing. The terminals are preferably enclosed in a box 48, Fig. 2. In a modification the terminals are on opposite sides of theapparatus.
