Abstract: A V-shaped crankarm so arranged, constructed, and mounted that when the piston and piston pin are at top dead center and the greatest resistance to the downstroke is made by the crankarm, the V-crankarm will transfer the force of combustion via a crankpin arm portion, which is fixed at an angle to a crankshaft arm portion lying in a plane substantially perpendicular to the axis of the cylinder, in order to affect rotary motion.

Abstract: A V-shaped crankarm so arranged, constructed, and mounted that when the piston and piston pin are at top dead center and the greatest resistance to the downstroke is made by the crankarm, the V-crankarm will affect the resistance to the downstroke and transfer the power of the downstroke to rotation of the crankarm and the crankarm.

Abstract: A fluid drive transmission system removably mounted to the axle of a motor vehicle. A power output drum connected to the wheel forms in part a fluid chamber. A power input rotor keyed to the axle extends through the center portion of the drum. Rotor blades and drum blades are positioned in the fluid chamber opposite one another. Bearings and fluid seals are positioned between the drum and the rotor so that the rotor and drum rotate freely relative to one another and the system can be removed as a unit from the axle without breaking the fluid seals.
