Abstract

An apparatus is disclosed herein for translating an input power force into an increased power output via a power multiplier unit. The apparatus comprises a plurality of lever arms pivotal carried on supporting structure so that a portion of the lever arm extending beyond the pivot connection constitutes a cam surface upon which roller cams operate to convert up-and-down lever arm movement to rotary movement of a sprocket gear carried on a rotatable shaft. The roller cams associated with each lever arm are arranged with respect to each other so that the cams operate from the lever arms as the lever arms are driven differentially. An output drive shaft is operably coupled to the sprocket gear for receiving an imparted driving force thereto. Timing linkage interconnects the lever arms with the sprocket and its shaft for augmenting the translation of power by smoothing the transition of movement between the roller cams and the lever arm cam surfaces.

Dependent claims

In a power multiplier apparatus for translating an input power force into an increased power output, the combination comprising:

a power multiplier unit having lever means characterized as having a mechanical advantage greater than one;
drive means including a main axle for imparting a driving force constituting said increased power output to a load;
cam means operably interconnecting said lever means to said drive means for transmission of power therebetween;
a timing means operably interconnecting said cam means with said lever means for maintaining synchronization between said cam means and said lever means;
said timing means includes a timing axle rotatably carried in parallel spaced apart relationship with respect to said main axle;
a driven timing gear fixed on said timing axle and a drive timing gear of greater diameter carried on said main axle;
a timing chain operably coupled about said drive and driven timing gears;
and
a crank shaft and connecting arm means movably mounting said timing axle to said lever arms.
