Abstract

378,709. Operating lift cages and doors. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.-(Assignees of McCormick, H. V. ; 573, Lafayette Boulevard, Long Beach, New York, U.S.A.) Oct. 23, 1931, No. 29457. Convention date, Nov. 26, 1930. [Class 78 (iii).] The operating motor 5 of a lift gate is controlled by an opening relav O and a closing relay C, these relays being controlled by a limit switch LS and a relay R. The relay R is connected to the lift control board so that when the lift is stopped this relay is de-energized and relay O is energized to open the doors, and when the circuit for starting the lift is completed relay R is energized and completes the circuitfor the closing relay C.
