Abstract
To boost RPM and to minimize the back and forth transfer of kinetic energy between a crank and a connector/reciprocating member in mechanisms having a stroke that is four times the crankpin offset, a connector which attaches the reciprocating member to the crank is weighted with counterweights to produce an effective connector center of mass at a location on the connector that, while rotating around the crankpin defines a motion perpendicular to the oscillation of the reciprocating member such that the resulting translational inertia of the connector is equal to but perpendicular and ninety degrees out of phase with the translational inertia of the reciprocating member so that their combined kinetic energy is constant, thus resulting in a zero transfer in energy between the crank and the connector/reciprocating member through each revolution unless external force is applied to the crank or to the reciprocating member.
