INDIAN MOTORCYCLE, 1902 



U. S. N. M. No. 309934; original; gift of Indian Motocycle Co. in 1930; photo-

The design of this machine was conceived in 1901 by the noted 

 bicycle racer Oscar Hedstrom for the Hendee Manufacturing Co., 

 of Springfield, Mass., later to be known as the Indian Motocycle Co. 

 This machine was made in 1902, the year that the model was first 

 offered for sale. The engine number is 150. 



The motorcycle is equipped with a 1%-horsepower, 1-cylinder, 4- 

 cycle, air-cooled, gasoline engine with an automatic intake valve and 

 a cam-actuated exhaust valve. Dry cells, a coil, a timer, and a spark 

 plug compose the ignition system, the timer being advanced and 

 retarded by a small lever at the front of the frame on the steering 

 head. This lever was used also for the compression release, lifting 

 the exhaust valve from its seat when moved to the retarded position, 

 and as an ignition switch. 



A float-equipped Hedstrom carburetor was supplied with gasoline 

 from the tank on the rear fender. Another lever, on the frame cross 

 bar, is designed for the fuel adjustment. A section of the tank con- 

 tained oil, which flowed by gravity through a sight glass into the 

 crankcase. A small exhaust pipe leads to a muffler beneath the 

 crankcase. 



Power was transmitted from the engine to the rear wheel by a 

 double-reduction spocket-and-chain drive on the left side of the 

 frame. As the machine has no clutch or change gear, the engine is 

 connected to the wheel at all times. A pedal-and-chain drive, in- 

 corporating a New Departure coaster brake, is provided on the right 

 side to supplement the engine. The brake is engaged by slight back- 

 ward pressure on the pedals. The pedals remained at rest when the 

 engine was propelling the machine. 



The diamond frame is of tubular construction, the wooden-rimmed 

 wheels mount 28-by-li/^-inch, single-tube, pneumatic tires, and the 

 complete machine weighs just under 100 pounds.

This 4-cylinder racer, built by Alexander Winton and known as the 

 "Bullet No. 1," was Winton's second racing car. He had previously 

 built a 1-cylinder racer for the first Gordon Bennett road race, held in 

 France in 1900. 



On September 16, 1902, at Cleveland, Ohio, Winton drove this car 

 on a horse track a distance of 10 miles in 10 minutes 50 seconds. This
