 lever engages the clutch. Metal guards cover the two chains. A 

 pedal-and-chain drive, incorporating a New Departure coaster brake,

 ground and the clutch engaged, the pedals can be used to crank the 

 motor for starting. The pedals are not driven by the forward motion 

 of the machine, and can be used to propel it in an emergency, in which 

 case the clutch would be disengaged. The brake is engaged by 

 slight backward pressure on the pedals.

This motorcycle was built by the Cleveland Motorcycle Co., of 

 Cleveland, Ohio, bears engine No. 5283, and cost $1Y5, f .o.b. Cleveland. 

 Advertisements of the period claimed Y5 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, 

 and was one of the most popular lightweight motorcycles of the 

 period. 



The machine is equipped with a 2i^-horsepower, 1-cylinder, 2-cycle, 

 air-cooled, gasoline engine of 21,4-inch bore and 234-inch stroke. 

 The total piston displacement is 131'^ 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-

 bar. The motor is lubricated by mixing oil with gasoline in the fuel 

 tank. Ignition is supplied by a Bosch high-tension magneto with

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

 joints, and the wheel base is 54 inches. The engine and gear box are

 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-disc 

 clutch composed of 13 hardened and ground steel discs. 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 running 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
