ABSTRACT:
A motion translation machine for converting reciprocating movement to rotational movement includes a frame that has drive pulleys, a drive belt connected to the drive pulleys, at least two perimeter pulleys and a perimeter belt which is supported by the drive pulleys and the perimeter pulleys. At least one drive pulley and both perimeter pulleys are restricted to a single direction of rotation. A reciprocating spindle is attached to the frame and includes a contact pulley which engages with a portion of the perimeter belt. Movement of the spindle causes a displacement of the belt, which, in turn, moves about the frame and drive and perimeter pulleys. Rotational restriction of the pulleys causes the perimeter belt to rotate in a single direction. Each cycle of reciprocation causes both drive pulleys to rotate in the same direction. The reciprocating spindle may be driven by human power or pressurized fluid, including internal combustion engines, and pneumatic and hydraulic cylinders.
