Patent number: 7255071Abstract: An apparatus useful in a two-stroke cycle engine or in a pump as a piston disposed within a piston cylinder. The piston cylinder has an intermediate piston cylinder head disposed transversely across the interior of the piston cylinder. The piston has at least one upright extension member extending upwardly from the lower portion. A piston top wall is disposed transversely to the piston cylinder side wall and is attached to the upper portion of the upright extension member of the piston. An upper chamber is defined above the piston top wall. An intermediate chamber is defined immediately below the piston top wall and a lower chamber is defined below the intermediate piston cylinder head. A tube connects the upper chamber with the lower chamber.Type: GrantFiled: August 18, 2005Date of Patent: August 14, 2007Inventor: Craig S. Beshore

Patent number: 4625685Abstract: The machine is an engine or pump with a box shaped piston positioned between two stationary sidewalls. Opposite inward ends and inwardly facing moving sidewalls of the piston act with the two stationary case sidewalls and a block-shaped central head to define a pair of working chambers. The piston moves as restrained by a crankshaft to extract or add energy to the working chambers. Force is transferred between the piston and the crankshaft by means of a slide block on the crankshaft and the inner surface of a pair of parallel walls connected to the box shaped piston. Through the use of suitable cams and valves, four-cycle, two-cylinder equivalent engines and two-cycle, one-cylinder equivalent engines can be produced per piston. The planar walls of the machine maximize displacement while reducing mechanical stress and allowing use of heat resistant coating material, such as ceramics for thermal protection so that radiantly cooling rather than separate fluid or gaseous cooling systems can be used.Type: GrantFiled: November 1, 1984Date of Patent: December 2, 1986Inventor: Craig S.

Patent number: 4586881Abstract: A compact lightweight engine or pump is constructed having a H-shaped piston, usually double acting. Each end of the piston has extending surfaces which form two moving sidewalls which act with two case sidewalls and a block-shaped head protrusion to define a working chamber with the appropriate top surface of the piston which moves to extract or add energy to the working chamber. Energy is transferred between the piston and a crankshaft by means of a slide block on the crankshaft and the inner surfaces of a pair of parallel walls forming the center of the "H" of the piston, whose opposite surfaces form the piston top surfaces. Through the use of suitable cams and valves, 4-cycle, 2-cylinder equivalent engines can be produced. With suitable porting, baffles, and/or auxillary compression means, 2-cycle engines can also be produced as well as air pumps.Type: GrantFiled: February 28, 1983Date of Patent: May 6, 1986Inventor: Craig S.
