ABSTRACT:
An improved crank apparatus for an internal combustion engine having a crankshaft, an arm extending outwardly of the crankshaft, a crank pin affixed to the arm, a sleeve member having an elongated slot formed therein so as to receive the crank pin therein, and a piston rod with a circular bearing area receiving the sleeve member therein. The crank pin has a generally rectangular configuration with first and second tabs extending outwardly from opposite sides of the crank pin. The first tab has an outer surface with a length greater than a thickness of the crank pin. The crank pin is slidable in the elongated slot during the rotation of the crankshaft. The circular bearing area has an insert key positioned therein. the insert key bears on a surface of the sleeve member during the rotation of the crankshaft. The insert key contacts the outer surface of the first tab during at least a portion of the rotation of the crankshaft so as to cause the crank pin to slide longitudinally through the elongated slot.
