Abstract:
1. A mechanism for converting a reciprocating action to unidirectional rotary motion comprising: a frame; a lever attached to the frame to pivot about a pivot point; an output shaft attached to the frame to rotate about a shaft axis; a first belt communicating with the lever to move in a first and second direction along a length of the first belt with reciprocating of the lever; a first rotatable capstan coupled to the output shaft, wherein the rotatable capstan provides an outer wall contacting a surface of the first belt with movement of the first belt; and a first drag element providing an outer wall contacting a surface of the first belt with movement of the first belt, the first drag element adapted to apply a drag tension against the first belt so that the first belt engages the outer wall of the rotatable capstan to rotate the same with a first direction of reciprocation of the lever and so that the first belt disengages the outer wall of the rotatable capstan with a second direction reciprocation of the lever to not rotate the same, wherein the first drag element provides an operator switching the drag element between a drag mode applying the drag tension against the first belt and a non-drag mode not applying the drag tension against the first belt.
