Abstract

A door actuator device to automatically, by means of a remotely actuated electrical switch, complete the opening as well as closing and locking cycle of a door. The actuator device is driven by a D. C., externally powered motor. In the opening cycle of a closed and locked door, the motor drives a latch mechanism which releases the door wherein the door lock and latch are interconnected and release of the latch also releases the lock. In the closing cycle of an open door, an automatic locking mechanism latches and locks the door member. The operator has the option of overriding the actuator device to open and close the door manually.
