Abstract
A reciprocating input rod lifts a heavy ball up an inclined circular track that provides a path for the ball to roll down by gravity. The ball's speed of rotation causes the track itself to rotate and this rotation provides useful output energy of rotation.
Claims5
A mechanism for converting linear reciprocating motion to continuous rotary motion and comprising in combination,
- (a) a frame defining at least one longitudinally extending guideway,
- (b) an elongated input member slidably received in said guideway,
- (c) said frame defining a circular path in said frame, said path having a horizontal central axis,
- (d) annular raceway means for rotation mounted in said circular path for movement in a vertical plane around said central axis, said raceway means defining an internal track also circular in contour,
- (e) a spherically contoured ball of smaller diameter then that of said circular track and provided in said raceway means, said ball adapted to be rotated in one direction by rotation of said raceway means in said one direction, and
- (f) ball engaging means mounted on said elongated input member and adapted to engage said ball between the ball's center of rotation and the said circular track whereby to move the ball up the track by causing the ball to slide on the track rather than to rotate in a direction opposite said one direction.
