Claim 4

A rotary engine according to claim 1, wherein said retention cam comprises a plurality of segments providing a continuous surface for said retention cam followers and wherein said means for biasing comprises a spring.

Claim 5

A rotary engine according to claim 1, further comprising an intake valve journaled within said first section of said central power shaft to allow the flow of fuel therethrough into said cylinder for ignition.

Claim 6

A rotary engine according to claim 4, further comprising means for controlling movement of said intake valve according to the rotation of said central power shaft.

Claim 7

A rotary engine according to claim 1, further comprising an exhaust valve journaled within said second section of said central power shaft to allow the escape of expended gases from said cylinder through said second section.

Claim 8

A rotary engine according to claim 6, further comprising means for controlling movement of said exhaust valve according to the rotation of said central power shaft.

Claim 9

A rotary engine according to claim 1, wherein said fuel intake system comprises: an air cleaner; a carburetor system to provide a proper fuel mixture to the engine; and, a manifold connecting said carburetor to said first section of said power shaft.

Claim 10

A rotary engine according to claim 1, wherein said second section of said power shaft has a first longitudinally extending bore and a second cross sectional bore connecting said first bore with the exterior of said power shaft and wherein said exhaust system comprises: a nozzle connected to each end of said second bore, angularly disposed therefrom, and rotatable with said power shaft; a cylindrical exhaust chamber non-rotatably mounted, concentrically, with respect to said power shaft and encasing said nozzles; a plurality of cupped fins immovably affixed to the inner surface of said exhaust chamber at approximately right angles to said nozzles whereby exhaust gases emitted from said nozzles, striking said fins, assists the rotation of said power shaft; and, means for exhausting said chamber to the atmosphere.

Claim 11

A rotary engine according to claim 1, wherein said ignition system comprises: means for generating a spark; an ignition plug; a housing carried by said rotating block for said plug having a removable cap in electrical contact with said plug; a radially extending disc non-rotatably mounted on said power shaft and in electrical contact with said means for generating a spark; and, an insulated ignition conductor means carried by said power shaft and in electrical contact with said radially extending disc and said cap for transmitting a spark from said means for generating to said ignition plug.

Claim 12

A rotary engine according to claim 10, wherein said insulated ignition conductor means comprises: a first insulated conductor bar provided within said power shaft; a second insulated conductor bar partially embedded in said power shaft and in electrical contact with said first bar and said cap; and, a third insulated conductor bar partially embedded in said power shaft and in electrical contact with said first bar and said radially extending disc.

Claim 13

A rotary engine according to claim 1 further comprising means for circulating a fluid within said fixed block to lubricate and cool the moving parts thereof.

Claim 14

A rotary engine comprising: a housing; a central power shaft establishing an axis through said housing and having first and second sections, each of said sections rotatably mounted in said housing; a rotating block connected between said first and second sections of said central power shaft; at least one cylinder within said rotating block; at least two pistons mounted within said rotating block communicating with said cylinder such that upon ignition said pistons are urged radially outward from the axis of said central power shaft; piston rods connected to said pistons; means for transmitting the radially outward movement of said pistons to said rotating block thereby imparting a rotational movement thereto; a fuel intake system; an exhaust system; and, an ignition system including: means for generating a spark; an ignition plug; a housing carried by said rotating block for said plug having a removable cap in electrical contact with said plug; a radially extending disc nonrotatably mounted on said power shaft and in electrical contact with said plug; a radially extending disc nonrotatably mounted on said power shaft and in electrical contact with said means for generating a spark; and, an insulated ignition conductor means carried by said power shaft in electrical contact with said radially extending disc and said cap for transmitting a spark from said means for generating to said ignition plug.

Claim 15

A rotary engine comprising: a housing; a central power shaft establishing an axis through said housing and having first and second sections, each of said sections rotatably mounted in said housing; a rotating block connected between said first and second sections of said central power shaft; at least one cylinder within said rotating block; at least two pistons mounted within said rotating block communicating with said cylinder such that upon ignition said pistons are urged radially outward from the axis of said central power shaft; piston rods connected to said pistons; means for transmitting the radially outward movement of said pistons to said rotating block thereby imparting a rotational movement thereto; a fuel intake system; an exhaust system; and, an ignition system including: means for generating a spark; an ignition plug; a housing carried by said rotating block for said plug having a removable cap in electrical contact with said plug; a radially extending disc nonrotatably mounted on said power shaft and in electrical contact with said plug; a radially extending disc nonrotatably mounted on said power shaft and in electrical contact with said means for generating a spark; and, an insulated ignition conductor means carried by said power shaft in electrical contact with said radially extending disc and said cap for transmitting a spark from said means for generating to said ignition plug.
