ABSTRACT:
A can opener has two pivotable handle members and a traction wheel and a rotary cutter movable by the handle members respectively between an inoperative position in which the wheel and cutter are spaced apart for mounting onto a can and an operative position in which they are close together for turning and cutting the can. An operating lever is pivotable back and forth. A first ratchet assembly is driven by the lever upon pivotal movement in one direction for rotating the wheel in one direction. There is also a second ratchet assembly driven by the lever upon pivotal movement in the opposite direction for rotating the wheel in the same direction. Upon pivotal reciprocation, the lever rotates the wheel in the direction operating the wheel and cutter continuously, turning and cutting the can.
