ABSTRACT:
A motor driven can opener includes a pivotal hand lever assembly which may be removed from the can opener frame. A latch on the frame engages an edge portion of the hand lever to retain the lever on the frame throughout its normal operating range. A plate on which a can cutting element is carried is mounted to slide on the forward surface of the lever. A tab projects from the plate and catches on a hardened steel pin of the frame to hold the hand lever against the actuator of a rotary switch which maintains the motor in its energized condition during shearing of a can lid. When the can shearing is completed, the tab releases from the pin to automatically deenergize the motor.
A manual crank may be employed as an alternative to electrical power. The motor is removed from the drive train when the crank is employed and brought back into the drive train when the crank is removed.
