Abstract:
1. A cam mechanism for converting rotary motion into a constant velocity reciprocating motion, the cam mechanism comprising: a driven shaft rotatable about an axis of rotation; first and second cam members mounted to said driven shaft for conjoined rotation therewith, each of said first and second cam members having a surface profile; a first pair of followers in contact with said first cam member on the surface profile thereof and on opposite sides thereof; a second pair of followers in contact with said second cam member on the surface profile thereof and on opposite sides thereof; a follower frame, said first pair of followers and said second pair of followers mounted to said follower frame for conjoint motion therewith; and wherein said first cam member and said second cam member each have a non-cardioid shape cam profile that results in a constant velocity linear reciprocation motion of said follower frame upon rotation of said driven shaft about said axis of rotation.
