Air cooling system for rotary combustion engine

Claim 1

IN A ROTARY COMBUSTION ENGINE, AN OUTER BODY HAVING A PERIPHERAL WALL INTERCONNECTED WITH A PAIR OF END WALLS THE RADIALLY INNER SURFACE OF SAID PERIPHERAL WALL AND THE AXIALLY CONFRONTING FACES OF SAID END WALLS FORMING A CAVITY DISPOSED ABOUT AN AXIS, INTAKE MEANS IN ONE REGION OF SAID OUTER BODY COMMUNICATING WITH THE INNER SURFACE OF SAID PERIPHERAL WALL, A COMBUSTION ZONE IN ANOTHER REGION OF SAID OUTER BODY AND EXHAUST MEANS FOR DISCHARGING THE GASES PRODUCED IN SAID COMBUSTION ZONE THROUGH SAID OUTER BODY WHEREBY TO DEFINE A SECTOR IN SAID OUTER BODY FROM SAID COMBUSTION ZONE TO SAID EXHAUST MEANS WHICH IS RELATIVELY HOTTER THAN THE REMAINING PORTIONS OF SAID OUTER BODY, A PLURALITY OF SAID PERIPHERAL PROJECTING FROM THE OUTER PERIPHERY OF SAID PERIPHERAL WALL, SAID FINS BEING NORMAL TO AND CLOSELY SPACED ALONG AN AXIS PARALLEL TO SAID OUTER BODY AXIS, SAID COOLING FINS HAVING A CIRCUMFERENTIAL EXTEND EQUAL TO SAID RELATIVELY HOTTER SECTOR, BAFFLE MEANS COVERING AND SEALING THE RADIALLY OUTER ENDS OF SAID COOLING FINS TO FORM A PLURALITY OF CLOSED INDIVIDUAL COOLING PASSES HAVING OPEN ENDS AT EACH END OF SAID RELATIVELY HOTTER SECTOR, EACH OF SAID END WALLS BEING FORMED BY A PAIR OF SPACED END WALLS, A PLURALITY OF COOLING FINS EXTENDING FROM ONE TO THE OTHER OF SAID SPACED END WALLS AND PARALLEL TO SAID OUTER BODY AXIS THEREBY FORMING PASSAGES FOR SAID COOLING AIR, SAID PASSAGES EXTENDING ARCUATELY ABOUT SAID OUTER BODY AXIS IN SAID RELATIVELY HOTTER SECTOR, ONE END OF EACH OF SAID PASSAGES COMMUNICATING WITH THE RADIALLY OUTER SURFACE OF SAID END WALLS AT THE END OF SAID COMBUSTION ZONE REMOTE FROM SAID EXHAUST MEANS, AND THE OTHER END OF EACH OF SAID PASSAGES BEINIG ADJACENT THE EXHAUST MEANS, SAID BAFFLE MEANS EXTENDING AXIALLY TO COVER BOTH SPACED WALLS OF BOTH END WALLS, DUCT MEANS FORMING A PASSAGEWAY FOR COOLING AIR EXTENDING SUBSTANTIALLY IN THE DIRECTIONN OF SAID OUTER BODY AXIS AND OVERLYING SAID BAFFLE MEANS, OPENING MEANS THROUGH SAID BAFFLE MEANS COMMUNICATING SAID DUCT MEANS TO SAID INDIVIDUAL COOLING PASSAGES SURROUNDING SAID PERIPHERAL WALL INTERMEDIATE THE ENDS OF SAID INDIVIDUAL COOLING PASSES, SAID COOLING AIR UPON PASSING FROM SAID DUCT MEANS THROUGH SAID BAFFLE OPENING BEING DIRECTED IN TWO OPPOSITE CIRCUMFERENTIAL COOLING PATHS AROUND SAID PORTION OF SAID PERIPHERAL WALL AND SAID BAFFLE OPENING BEING DISPOSED RELATIVE TO THE ENDS OF SAID CIRCUMFERENTIALLY EXTENDING FINS SO AS TO PROVIDE AN EQUAL PRESSURE DRIP IN EACH OF SAID COOLING PATHS AND FURTHER OPENING MEANS THROUGH SAID BAFFLE MEANS COMMUNICATING SAID DUCT MEANS TO SAID ONE END OF EACH END WALL COOLING PASSAGES.
