Abstract
A crank and connecting rod mechanism having an angularly disposed connecting rod and mirror image gear sets, each comprising: a crank gear rotatably mounted on a crank gear shaft, having a crankpin pivotally connected to and driven by the connecting rod, the crankpin following the path of a roulette of a centered trochoid about a first stationary gear as the crank gear is driven about the first stationary gear and a crankshaft driven gear is driven about a second stationary gear, a counterbalanced radial arm affixed to a drive shaft at a pivot point of the counterbalanced radial arm, the counterbalanced radial arm driving the drive shaft at the pivot point and the crank gear shaft at an outer radial arm bearing, the drive shaft driving a drive shaft gear, which drives an output gear that drives an output shaft.
