Combustion pushed the cylinder head away from the piston, Con rods rotated around the crankpin, unlike any others that only oscillated on the journal. Very similar to the modern rotary vane pumps use in air tools except reversed. Originally built to provide good cooling when air speeds were 45 MPH in 1908 they jumped to 120 MPH in 1912 at the Rheims air races.
