Abstract: A mechanical mechanism, for use in an internal combustion engine for changing rectilinear movement of a piston to rotational movement of a crankshaft, is of simple construction and has a minimum number of parts. A small gear with teeth formed on its external peripheral portion is stationarily mounted to a wall of an engine, and receives a first portion of a crankshaft, the crankshaft being rotatable with respect to the gear and the wall about an axis. A second portion of the crankshaft opposite the first is also mounted for rotation with respect to a stationary member. A third portion of the crankshaft is offset from the axis. A balancing structure comprising first and second balance bodies interconnected by a collar, and is mounted so that the crankshaft third portion is received within the collar and rotatable with resepct to the collar.

Abstract: A fuel vaporizing device for use with a carburetor to more efficiently vaporize and distribute the fuel portion of the air/fuel mixture. The device is mounted between the carburetor and intake manifold and positions a hot plate element in the flow path of each carburetor barrel discharge. Each hot plate is comprised of a solid metal disk in which a plurality of through bores are formed. Heat is supplied by a conduit extending through the disk, but does not intersect any of the through bores. The conduit is connected to both the intake and exhaust manifolds so that hot exhaust gas passes therethrough at relatively high velocity. To assure uniform flows of exhaust gas, an exhaust reservoir is provided in the connecting line between the exhaust manifold and the vaporizing device.
