Abstract

649,437. Door operating apparatus. MARRYAT & SCOTT, Ltd., and HONEY, L. W. Nov. 25, 1948, No. 30640. Addition to 584,343. [Class 65(i)] Apparatus according to the parent Specification for closing a lift car gate is provided with means for simultaneously closing the landing gate instead of requiring a separate set of apparatus for that purpose. The doorclosing pin 13 on the driving chain 12 engages a lever 103 pivoted on the car gate at 102 and engaging at its lower end a spring-loaded lever 108 also pivoted on the car gate at 107 and carrying a roller 100 for contact with an abutment 101 on any landing gate. The spring 111 acting on the lever 108 provides for lost-motion before the drive of the chain is taken by any gate and retracts the roller 100 from contact with the abutment 101 when the gates are closed and the driving power is cut off. The power drive may be set into operation automatically after a predetermined lapse of time from the opening of the car gate.
