ABSTRACT:
An electrically powered can opener with power-pierce and automatic shutoff has a permanently assembled (together) combination cutter mounting plate and operating lever that is selectively removable from its operating position upon the can opener frame. The cutter mounting plate and operating lever combination is secured in position on the frame by three strategically located bosses that assures a holding force is exerted at points advantageous for maintaining good alignment of the cutter mounting plate at all times. The removal and reinstallation of the cutter mounting plate and operating lever is easily accomplished by the manipulation of a spring biased push button latch. An integral lever pivots upon the back of the frame and contacts the switch to cause energization of the motor for cutting the can lid and automatic deenergization when the lid has been completely severed from the can. The minimization of friction between the cooperating affected parts allows a small spring to cause the integral lever to pivot and automatically deenergize the motor when the can cutting is completed. A resilient can guide extends from the frame at a point exterior to the cutter mounting plate to assist in properly engaging the can. This movable can guide cooperates with the cutter wheel and a fixed can guide extending from the cutter mounting plate, while not interfering with the automatic shutoff.
