Abstract: A rotary valve device for internal-combustion engines, said device comprising an elongated, tubular drum having an exhaust-manifold system disposed therein and a plurality of fuel passages, forming a fuel-intake system having fuel-intake ports and fuel-outlet ports positioned in the peripheral wall of the drum, whereby lean and rich fuel mixtures can be separately but simultaneously deposited in each combustion chamber of an internal-combustion engine, as the tubular drum rotates within the cylinder head, so that a complete burning of the fuel takes place. A cooling means, such as a water jacket, is interposed between the inner, tubular, manifold-exhaust conduit and the fuel passages -- the jacket being provided with openings at the terminating ends thereof for connecting the water flow to the cooling system of a conventional-type engine.

Abstract: This disclosure is directed to a rotary-cam, internal-combustion, radial, 4-cycle, 6-cylinder engine comprising a stationary motor block adapted to operably receive a dual set of pistons, each set thereof being juxtaposed to the other, having their respective rods extending outwardly from the piston chamber and operably attached to a rotatable casing by means of a cam follower secured to the free end of the rod and disposed within a cam channel forming part of the casing, thereby allowing each adjacent piston to simultaneously reciprocate together as the casing rotates with the main drive shaft; and wherein the main shaft incorporates both the fuel-intake system and the motor-exhaust system, said main drive shaft being fixedly connected for rotation with the casing.
