Abstract: The dynamic power booster is an apparatus which utilizes rotational input power for driving a crank lever in circular rotation. The crank lever drives a pivotally mounted lever assembly, having a first and a second lever slidably connected with one another, in a reciprocating and oscillating movement.An oscillating arm is movably mounted by its first end portion on the second lever adjacent to the assembly pivot mounting arrangement, and the second end portion of the oscillating arm is attached to one way clutches which are attached to an output shaft.Upon rotation of the crank lever, the combination lever assembly moves into an oscillating and reciprocating motion and simultaneously oscillates the oscillating arm, which in turn via the one way clutches rotates the output shaft.
