Abstract
A scotch yoke mechanism for converting rotational movement into reciprocating linear movement and having an adjustable stroke length. The scotch yoke mechanism includes a stroke length toggle eccentrically connected to a cam such that the stroke length toggle may assume one of first and second positions. The first position defines a first stroke length which is shorter than a second stroke length defined by said second position. Rotational movement of the cam causes the stroke length toggle to assume the first position when the cam is rotated in a first direction to assume the second position when the cam is rotated in a second direction opposite the first direction.
