Abstract
A device for translating rotary to linear motion and vice versa includes a reciprocating linearly moving shuttle with a central aperture. The aperture has a pair of opposing conjugate bearings protruding towards the center and which capture therebetween a pair of conjugate drivers rotatably mounted to the crankpin of a rotatable crankshaft with the axis of crankshaft rotation perpendicular to the linear path of the shuttle. The conjugate drivers are free to rotate about the crankpin and articulate independently of each other through a selected angular range. When the crankpin, including the conjugate drivers, is inserted into the aperture of the shuttle with the conjugate drivers engaging the racks, motion is transferable between the crankpin and the shuttle through the conjugate drivers.
