CATALOG OF THE AUTOMOBILE COLLECTION 27 



was an average speed of 55.38 miles an hour, a very creditable showing 

 for that time. Again, on March 26, 1903, at Daytona Beach, Fla., 

 Winton covered a mile in 52.2 seconds, an average speed of 68.96 miles 

 an hour. 



The car, as now exhibited, is a little the worse for wear and neglect 

 during its former years, and some parts are missing. However, the 

 engine and the rear-axle gearing are free to turn over, the clutch can 

 be depressed, and the transmission gear shifted. 



The massive, water-cooled, 4-cylinder engine has a bore of 6 inches 

 and a stroke of 7 inches, with a total piston displacement of 792 cubic 

 inches. It is mounted at the front of the chassis, with the crankshaft 

 parallel to the sides of the frame. Two support arms on each side of 

 the engine, cast integrally with the crankcase, support the engine in the 

 frame. The crankcase and the base are of aluminum, while the 1-piece 

 water jacket of the four cast-iron cylinders is formed of brass sheeting 

 screwed in place, all of which aided materially in reducing the weight 

 of the machine. Other aluminum parts of the engine are the timing- 

 gear cover at the front, the intake manifold and the covers for the 

 cages of the overhead intake valves, the water pump, the carburetor, 

 and the base of the air pump. 



The engine is of the 4-cycle type, with camshaft-actuated exhaust 

 valves on the left side and automatic, overhead intake valves located 

 directly over the exhaust valves. The carburetor is on the right side 

 of the engine and is connected to the intake manifold on the left by a 

 vertical riser leading up the right side and over the top of the engine. 

 The exhaust ports lead to a heavy sheet-metal exhaust manifold, which 

 in turn is connected to a large muffler under the left side of the car. 

 A cut-out is fitted to the rear of the muffler and is controlled by a lever 

 at the front of the driver's seat. The muffler was not always on the 

 car ; it was often removed for racing, as shown in the illustration. 



A crank throw on the forward projection of the crankshaft drives a 

 reciprocating-piston air pump, which supplied compressed air for the 

 unique system of controlling the engine speed. When the engine was 

 running, compressed air was supplied to the lower ends of small cylin- 

 ders enclosing pistons on the stems of the four intake valves. The air 

 pressure opposed the motion of the valves being drawn down and 

 opened by the engine suction. Two relief valves, one a foot plunger, 

 the other a hand valve, were used to vary the pressure on the valve 

 pistons and so control the speed of the engine. As the air pressure 

 was reduced, the valve opening and the engine speed were increased. 

 The aluminum, float-equipped carburetor contains no throttle valve. 



An oil reservoir of sheet brass, secured to the right side of the engine, 

 dielivered oil by gravity to a 16-unit, sight-drip oiler located at the
