Abstract
A battery powered can opener includes a cutter assembly that is pivotally mounted at the front of a housing for a motor, batteries for powering same, a speed reducing gear train and a switch for controlling energization of the motor. The clutch assembly is movable to a position for retaining the opener on the bead of a can whose top is to be severed. After mounting of the opener on a can, a manually operated switch control remote from the cutter is operated to start the motor which acts through the gear train to drive the opener around the bead. As the motor starts, a wedging action between the can cover and the blade of the cutter assembly causes the latter to pierce the can top, and continued energization of the motor results in the blade cutting the top along the bead. Cutting results in the production of a reaction force that acts through the cutter assembly and a latch to hold the motor energizing switch closed after the switch control is released. When the can top is completely severed from the can body, the reaction force terminates and the latch releases the switch control to deenergize the motor automatically.
