Abstract
A locking pin actuating mechanism provides rapid and secure operation of lock control devices such as used with aircraft for bombay doors. A downlock-pin actuator includes a motor and flywheel coacting with a clutch to drive a gear and linkage system. The motor drives a single revolution clutch to insert and retain a lock pin in a locked position. A second revolution extracts the pin to unlock the mechanism. Adjustable position sensing microswitches generate signals to control the insertion and extraction of the lock pin.
