Abstract
This invention is a device and method for avoiding dead centers in an in-line slider-crank mechanism when it is used to convert linear to rotary motion. The usual straight connecting rod is replaced by an L-shaped connecting rod operating in conjunction with two deflecting pillars. The side-arm of the L-shaped connecting rod travels between the two pillars which are strategically sized and placed, and intended to deflect the side-arm. As a consequence, the crankpin end of the connecting rod is automatically deflected away from the dead center positions, thus avoiding them, and enabling the rotation to become continuous and un-interrupted.
