Abstract: An internal combustion rotary engine with multiple cylinders and rotary crankcase supported on a pair of engine stub shafts. The connecting rods are each connected to a different center arranged evenly around the drive center of a stepdrive element. The stepdrive element which is polygonal or circular is offset from the rotational axis of the crankcase within which it revolves. The stepdrive element drives the crankcase through a series of links. As each piston fires the connecting rod is inclined to the piston travel axis and the angle between the connecting rod and the stepdrive element center is close to 90 degrees. As the piston moves through its power stroke the cylinder rotates with the crankcase maintaining the mechanically advantageous 90 degree angle for about 100 degrees of crankcase rotation. Symmetric and asymmetric cylinder layouts, Diesel and 2-stroke layouts are disclosed.

Abstract: This invention makes use of the combined advantages of the internal combustion engine and the turbine. A rotary internal combustion engine has a base and a housing rotatably mounted to the base and forming a radial cylinder. An output shaft is rotatably mounted concentric with the housing and has an arm rigidly extending therefrom. A piston slides in the cylinder for forming a combustion chamber, the piston being operatively connected to the arm. Relative rotational movement between the housing and the output shaft causes the piston to reciprocate in the cylinder.

Stop means are arranged on the shaft for limiting the relative movement between the shaft and the housing. Brake means are arranged on the base and the housing for facilitating a starting and a stopping sequences of the engine.

Abstract: An internal combustion engine combines the efficiency of a radial engine with the practicality of a piston and crankshaft arrangement. A stationary frame supports a stationary sun gear, and a rotor is pivoted about the axis of the sun gear. The rotor carries three crankshafts at 120.degree. intervals, each having an eccentric portion. Each crankshaft is fixed to rotate with a respective planetary gear, and all the planetary gears mesh with the sun gear and have the same pitch diameter as the sun gear. The crankshaft eccentricity is substantially 1/3 times the pitch radius of a planetary gear. The eccentric portion of each crankshaft has roller means rotatable about the same axis as the connection between the connecting rod and the eccentric portion, and a ring member with an internal surface surrounds and contacts all of the roller means simultaneously, the ring member being free to rotate about its own axis. Three valves admit the combustible mixture to each cylinder.

Abstract: Internal combustion engine having a rotating closed cylinder housing mounted to a fixed frame and means to harness the rotation of the cylinder housing to rotate an output shaft. The cylinder housing contains a double ended piston to define two combustion chambers between the corresponding ends of the piston and the cylinder housing. Alternating combustion of fuel in the combustion chambers reciprocates the piston within the cylinder housing. A Scotch yoke mechanism linking the cylinder, piston, and frame harnesses the reciprocating motion of the piston within the cylinder housing to rotate the cylinder housing. In a preferred embodiment of the invention a second cylinder housing counterrotates about a common axis to cancel the spin angular momentum of the first housing and to double the power provided by the engine. The engine employs a two stroke combustion cycle in a preferred embodiment of the invention.

Abstract: An engine including a piston yoke assembly reciprocating within a rotor assembly disposed for rotation within a fixed casing. The rotor assembly is of elliptical configuration to form a pair of exhaust chambers located between the assembly and the casing interior. The rotor assembly defines closed end combustion chambers and fuel-air chamber within which the yoke portion of the piston yoke assembly reciprocates to pressurize fuel-air charges for transfer to the combustion chambers. The piston yoke assembly comprises a part of the rotor assembly but moves about a fixed component carried by the engine casing resulting in reciprocal movement of the piston yoke assembly within the rotor assembly. Power is delivered to the rotor assembly by ignition of a fuel-air charge acting on a piston and yoke assembly off center from the fixed casing component. Exhaust ports within the rotor assembly provide for the ejection of exhaust gases asymmetrical to the rotor axis to impart torque to the rotor.

Abstract: A pump supplies pressurized lubricant to an internal combustion engine from an external reservoir through a closed loop system. Delivery channels extending through the crankshaft, connecting rod and other components, supply the pressurized lubricant to the several areas of relative movement. Return channels, extending through the components, conduct lubricant from the several areas to the reservoir. Fuel-air mixture from a carburetor enters the crankcase through the open end of the crankshaft and moves through ports within the several cylinders to the respective combustion chambers. Selected ports are sequentially closed by a valve plate carried by the crankshaft. Incomplete products of combustion are exhausted into an auxiliary exhaust outlet for recycling with the fuel-air mixture. Retainer members engaging the spark plugs assist in dissipating heat therefrom.

Abstract: A rotary internal combustion engine is provided with a central housing having a plurality of cylinders radially disposed around the housing. The cylinders are disposed about the housing such that reciprocal movement of pistons inside of the cylinders results from rotational movement of the central housing about a stationary center axis, so that the pistons are not brought to an instantaneous stop at a point in their cycle at which a 180.degree. change in direction occurs. By not having to overcome such inertial forces, a substantial increase in energy output is achieved. The rotating housing is mounted on supports to stabilize the engine and transmit rotational movement to a driven device. The exhaust output of the individual cylinders is directed outwardly to provide additional torque in the form of a jet action.
