Abstract: A rotary internal combustion engine of the type having pistons mounted for reciprocatory movement in respective cylinders which are arranged in equally-spaced relationship around a longitudinal axis of rotation, said axis being the axis of rotation of an output shaft passing rotatably and sealably through apertures of respective first and second end plates of a housing within which the pistons and cylinders move as part of a rotatable rotor assembly secured to said output shaft, while the pistons are simultaneously movable reciprocably in the cylinders, cam follower means being associated with each piston and adapted to coact with undulating cam track means around the housing. Cyclical combustion of fuel in the cylinders imparts reciprocation to the pistons with resultant thrust against the cam track means so as to cause rotation of the rotor assembly and output shaft.

Abstract: A machine is disclosed that may be configured as a pump, a compressor or an engine. The machine displaces volume by means of pistons that are connected to a driveshaft without oscillating connecting rods. Cylinders are disposed in a rotating cylinder block that rotates on an axis inclined to the axis of rotation of the pistons. A spherical member centers the driveshaft with respect to the cylinder block, and a biasing means urges the cylinder block against a bearing surface. Displacement may be varied by varying the angle of inclination of the two axes of rotation.

Abstract: A rotary internal combustion engine having a plurality of pairs of angled pistons, each pair having a power piston and a corresponding supply piston. As the power piston of a pair fires to provide rotation for the engine, the corresponding supply piston draws a fresh fuel air charge from the center section of the engine. As the supply piston compresses the fuel air mixture, the mixture is delivered at the top of the power cylinder for the next firing. The exhaust port is located at the bottom of the power piston stroke and the fuel intake is at the top of the cylinder, to increase the efficiency of the engine. Roller bearings are mounted between each cylinder block and an engine outer casing to support the engine.

The housing (52) carries a lead wire (88) for firing a spark plug (84) associated with each cylinder bore (14) as the cylinder bore (14) rotates past the lead wire (88). An oil duct (92) is provided for circulating oil from the lower housing (68) to the upper portion of the upper housing (52). A fuel and air mixture is introduced into the individual cylinder bores (14) through an inlet port (16) and is evacuated, when spent, through an exhaust port (18).

As the cylinders (34) rotate in an engine cavity (49) about a drive shaft (24), head ends (104) of the cylinders (34) cyclically pass stationary fuel injection means (28) and a stationary exhaust aperture (30) located rotationally downstream from the fuel injection means (28).

The air intake port (130) is provided at a location at which rotation of the cylinder (34) in the cavity (49) tends to force or scoop air into the cylinder (34). In particular, the air intake port (130) is provided on a rotationally leading portion of a peripheral portion of the cylinder wall.

Abstract: A bank of piston and cylinder assemblies is formed in a cylinder block and is mounted for rotation within bearings. The piston rods are operatively connected to the pistons and bearing supports on an angled plate journalled for rotation at one end of the block and shafts extend axially from the block and the plate and are connected together by a universal joint for rotation as a unit. A centrally located fuel/air chamber is formed axially through the block and fuel/air compression and vaporizing fans rotate with the chamber as the block rotates and feeds fuel/air mixtures through inlet ports to the cylinders successively as the pistons uncover the inlet ports. An exhaust ring surrounds the block and is adjustable radially and exhaust ports from the cylinders coincide with an exhaust outlet in the ring also successively. The engine operates on the two stroke principle, each cylinder firing every 360.degree. of rotation but splash lubrication is provided thus eliminating fuel/oil mixture.

Abstract: An internal combustion engine having two rotating cylinder blocks in each of which is formed a plurality of cylinders to receive portions of pistons that extend partially into each cylinder block. The cylinder blocks are angled relative to one another and the pistons are similarly angled to cause variation in the free volumes of the cylinders as the cylinder blocks rotate. A support shaft passes through the centers of the cylinder blocks to provide support for the cylinder blocks via bearings on the support shaft. Air is introduced into the cylinders via central cavities in the cylinder blocks and fins and slots are formed on, and in, respectively, the interior walls of the cavities to impart rotation to air in the cavities. A series of rings, through which the cylinders pass, are formed on the end of each cylinder block that faces away from the other cylinder block to circulate cooling air drawn into a housing in which the blocks are mounted about the cylinders.

Abstract: A piston and cylinder machine, e.g. an engine or pump, in which the cylinder rotates about a first axis from which the cylinder is spaced, and the piston rotates about a second axis inclined to the first with the result that during the rotation, the piston reciprocates relative to the cylinder. Gas flow is controlled by a rotary valve which communicates with the cylinder and which rotates about an axis parallel to or coincident with the first axis. The piston is maintained in position relative to the cylinder by restraining means in the form, for example, of flat abutment surfaces provided between the piston and a spherically-surfaced piston ring thereon so as to limit lateral movement of the piston ring relative to the piston.

Improved torque transmitting or reacting means for maintaining the correct relative orientation of the piston and cylinder are provided.

Abstract: An improved engine, particularly of the rotary type, or so-called angle piston type, having conventional components and characterized by a compressor serving as a supercharger interposed between the carburetor and the engine intake ports for compressing the combustible mixture; a bypass manifold for passing compressed combustible mixture to the suction side of the compressor; and a fine throttle means for controlling the proportion of combustible mixture bypassed for fine control and efficient combustion in the engine. The master throttle on the carburetor is employed only for major adjustments in power requirements. Also disclosed are details of critically located and designed intake ports and passageways and discharge ports and passageways to take advantage of centrifugal force of the angle piston type engine to obtain very nearly perfect scavenging, as well as details of employing a center section compressor for compressing the combustible mixture.

Abstract: An external combustion engine system adapted to utilize any of a number of expansible gases including steam, freon, thiophene, etc. The engine comprises a piston-driven unit which utilizes uniflow principles but is substantially more efficient than the conventional uniflow design because it provides means for conducting the exhaust from a primary side of the piston to a secondary side and thereby extracts additional energy from each gas charge through a second expansion before finally exhausting the gas to vacuum. In addition, the engine has a highly efficient and compact rotary design featuring a multi-cylinder barrel acting on a rotary torque conversion plate for minimizing friction and other energy losses. The design includes special valving for power and direction control and a simplified porting system for providing the aforementioned double gas expansion and permitting cold start-up without the need for bleed valves to drain condensate from the cylinders.
