1. A motion converter mechanism to be interposed between a driving device and a driven device to provide a rotary motion in one device and a reciprocatory motion in the other device, comprising:

  • a housing;

    a reciprocatory member mounted for reciprocatory movement along a longitudinal axis and having a first end coupleable to one of the devices;

    a rotary member mounted for rotary movement about a rotary axis and coupleable to the other of the devices;

    a crank arm having a first end pivotally coupled to said rotary member and a second end pivotally coupled to said reciprocatory member;

    and an alignment member extending transversely of said longitudinal axis and having a first end pivotally coupled to said reciprocatory member and a second end pivotally coupled to said housing such as to maintain said reciprocatory member in general coaxial alignment with said longitudinal axis, and thereby substantially to prevent side loading of said reciprocatory member during its reciprocatory movements.
