Abstract
A compact, electrically powered can opener with power pierce has a compound piercing lever comprised of a pivotally mounted hand lever and an interconnected, removable cutter mounting plate. The cutter mounting plate is removably and pivotally connected to the frame by a pin member latching combination. A first pin member extends rearwardly from the cutter mounting plate and is received in a suitable aperture in the can opener frame to pivotally attach the cutter mounting plate thereto. A cooperating latching combination, comprised of a latch arrangement located between the cutter mounting plate and the can opener frame and a slotted frame aperture which cooperates with a second, rearwardly extending cutter mounting plate pin, firmly maintains the cutter mounting plate in correct alignment with respect to the frame as the cutter mounting plate pivots, precluding axial separation therebetween throughout a major portion of the pivot arc. However, when the cutter mounting plate is rotated to a predetermined angular position, the latching combination disengages for easy removal of the cutter mounting plate from the can opener frame. A third pin member, also extending rearwardly from the mounting plate, engages a suitably constructed slot in the hand lever so that manipulation of the hand lever correspondingly effects proper movement of the cutter mounting plate. The slot in the hand lever is uniquely shaped to insure recapture of the mounting plate third pin member when the removable mounting plate is reattached to the frame. Motor activation means, interconnected with the piercing lever, activates the motor in response to upwardly directed forces on the hand lever occurring when the cutter wheel engages a can, thereby effectuating power pierce. Additionally, when a can is not in the opener, the heel portion on the piercing lever enables it to fulcrum on a frame boss in response to minimal piercing lever movement, thereby actuating the motor and operating accessory cutlery grinding means (when same is provided) without additional switches.
