1. An apparatus for translating reciprocating linear motion provided by an input shaft into rotational motion comprising:
a gear assembly comprising:
a pair of opposed left and right gear rails spaced a variable distance apart, each of said gear rails having a plurality of inward facing gear teeth and top and bottom ends respectively;
a pair of opposed left and right rail frames for engaging said left and right gear rails, each of said left and right rail frames having top and bottom ends and each of said left and right rail frames having a spring disposed between said rail frame and said gear rail;
an upper block secured to said opposed left and right rail frame top ends and to said input shaft;
a lower block secured to said left and right rail frame bottom ends; and
an annular drive gear having a plurality of teeth around the circumference thereof, said drive gear disposed between said left and right gear rails and selectively engaging the teeth thereof, whereby linear motion of said input shaft imparts linear motion to said gear rails thereby rotating said drive gear.
