Abstract
Two reciprocating cylindrical drive cams, each with a continuous spiral groove, mounted on a splined shaft, a driven cylindrical cam with two continuous spiral grooves mounted on a parallel shaft, and two reciprocating pins mounted in an intermediate housing between the drive cams and driven cam. The upper ends of the pins engage the grooves of the drive cams, and the lower ends of the pins engage the grooves of the driven cam. When the drive cams are locked together on the splined shaft, the drive cams revolve and the grooves impart reciprocating motion to the pins which impart revolving motion to the driven cam. When the drive cams are allowed to reciprocate on the splined shaft, the drive cams do not revolve and no motion is transmitted to the pins or to the driven cams.
