Abstract
A crankshaft and connecting rod assembly comprises a driver having a crank lobe with a shank received in a radial slot through a shaft so as to be driven thereby. The crank lobe has an inner side that operably contacts the shaft and an outer side that operably contacts a bore in a connecting rod and the shank has an end that also operably contacts the bore. The outer side of the crank lobe and the end of the shank each have a semi-circular cylindrical surface and these surfaces are located diametrically opposite each other and have a common axis eccentric and parallel to that of the shaft and a radius substantially equal to that of the bore whereby upon shaft rotation the crank lobe through sliding contact with the bore drives the connecting rod while the end of the shank slidingly follows the bore and cooperates with the crank lobe to prevent radial movement of the driver on the shaft to thereby maintain such drive.
