This model Kitty Hawk engine was designed by Edgar T. Westbury, of England, in the 1940s. The actual builder is unknown. The model was built by a toolmaker who worked for the Pulseometer Pump Company in Berkshire, England. It was machined on a treadle lathe we believe he fabricated before working the engine. It is a 4-cycle air-cooled engine designed to burn gasoline on spark ignition. Lubrication is accomplished by the use of two check valves strategically placed in the crankcase that circulate the oil as the piston moves up and down. As the piston moves up it creates a vacuum in the crankcase that closes the bottom check valve sucks oil in from an external reservoir through the top check valve; when the piston returns down it produces pressure closing the top check valve and forcing oil out through the bottom check valve back into the reservoir.
