CLEVELAND MOTORCYCLE, 1918 

 Gift of Richard and Russell Fiedler in 1951 (USNM 313692) 



This motorcycle (fig. 98) was built by the Cleveland 

 Motorcycle Co., of Cleveland, Ohio, bears engine No. 5283, 

 and cost SI 75, f.o.b. Cleveland. Advertisements of the 

 period claimed 75 miles from a gallon of fuel, and 35 to 40 

 miles an hour for this machine. This make of motorcycle 

 was introduced in August 1915, at which time the f.o.b. price 

 was $150. It was one of the most popular lightweight 

 motorcycles of the period. 



The machine is equipped with a 2 ^-horsepower, 1 -cylin- 

 der, 2-cycle, air-cooled, gasoline engine of 2 1 /2-inch bore and 

 2%-inch stroke. The total piston displacement is 13V2 cubic 

 inches. The cylinder casting and its integral head are of 

 cast iron. The carburetor, bolted to the inlet port at the 

 front of the cylinder, is a Brown and Barlow, float-feed, 

 single-jet type with auxiliary air control. The two hand- 

 operated controls of the carburetor are located on the right 

 handle bar. The motor is lubricated by mixing oil with 

 gasoline in the fuel tank. Ignition is supplied by a Bosch 

 high-tension magneto with spark plug. 



The frame is of heavy-gauge seamless steel tubing, brazed 

 at the joints, and the wheelbase is 54 inches. The engine 

 and gear box are secured in the frame by two large suspen- 

 sion bolts. The gear box is integral with the aluminum 

 crankcase and contains a set of 2-speed sliding gears of 

 chrome-nickel steel and a heat-treated, alloy-steel worm 

 with a titanium-bronze worm gear, as well as a multiple- 

 disk clutch composed of 13 hardened and ground steel disks. 

 The low ratio of the gear box is 10 to 1, and the high ratio 

 6.1 to 1. The transmission gears are lubricated by run- 

 ning in an oil bath. Forward motion of a hand lever on 

 the left side of the machine engages the clutch. A brake 

 pedal, also on the left side, operates a contracting brake band 

 on a drum on the left side of the rear wheel. Gear changes 

 are made by a pedal operated by the right foot. A kick 

 starter is attached to the left side of the gear box. The rear 

 wheel is driven by a roller chain from a sprocket on the out- 

 put shaft of the transmission, on the right side of the 

 machine. There is no guard over the chain.
