Abstract
Abstract An internal combustion engine adapted for use in automobiles and other devices capable of operation under high compression while effecting more complete combustion of its fuel. The engine is of the piston type with the piston mechanically arranged for both oscillatory and related vertical reciprocitory motion. The cylinder is double-headed the heads being oriented in such a manner with respect to the piston faces that maximum compression is effected on the firing stroke of the engine. The double head cylinder permits more complete combustion of the gasoline mixture.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
130 words
An internal combustion engine comprising a cylinder, a reciprocatory piston disposed in said cylinder, said cylinder having a head at one end with an operative face which is both planar and not normal to the reciprocating axis of said piston, said piston having an opposing operative face also planar and not normal to said axis, a rotary device having a universally mounted bearing disposed off the center of rotation of said device, an output shaft in driven connection with and at the center of rotation of said device, said cylinder having an opening in its side wall structure, and a piston rod rigidly connected to said piston, extending through said opening and in sliding connection with said bearing whereby rotary and reciprocating motion is imparted to said piston during operation.
Claim 2
Dependent Claim
130 words
An internal combustion engine comprising a cylinder, a reciprocatory piston disposed in said cylinder, said cylinder having a head at one end with an operative face which is both planar and not normal to the reciprocating axis of said piston, said piston having an opposing operative face also planar and not normal to said axis, a rotary device having a universally mounted bearing disposed off the center of rotation of said device, an output shaft in driven connection with and at the center of rotation of said device, said cylinder having an opening in its side wall structure, and a piston rod rigidly connected to said piston, extending through said opening and in sliding connection with said bearing whereby rotary and reciprocating motion is imparted to said piston during operation.
Claim 3
Dependent Claim
34 words
An internal combustion engine defined in claim 1, wherein the piston and cylinder at the other end thereof have opposing operative faces both planar and not normal to the reciprocating axis of the cylinder.
Claim 4
Dependent Claim
19 words
An internal combustion engine as defined in claim 2 wherein a spark device is provided in each cylinder head.
Claim 5
Dependent Claim
28 words
An internal combustion engine as defined in claim 3 where at least two exhaust ports and at least two carburetor inlet ports are provided in the cylinder housing.
