摘要
A mechanism vehicle converts rotary motion to reciprocal linear or arcuate motion of variable amplitude consisting of a tubular housing having a rotary member therein with longitudinal slots for accomodating a slide piece. A block carrying an offset pivot bearing is mounted in said housing in spaced relation to said rotary member and a crank arm is positioned between said pivot and a lug which is in offset hinged relation to a slide positioned in said slots so that rotation of said crank arm generates a cone. A carrier bearing and assembly translates the rotation of said crank arm into reciprocal linear movement of a pair of slide blocks positioned in slots in said housing. A threaded adjustment member determines the spacing between said rotary member and said block carrying the pivot bearing so as to vary the stroke of the slide blocks in relation to the position of the carrier bearing on the cone generated by rotation of said crank arm.
