but that they knew nothing of the actual bicycle. It is apparently 

 the only bicycle of its kind, and was probably built for Mr. Anderson 

 by a local machinist. Its weight is approximately 45 pounds. 



INDIAN MOTORCYCLE, 1902 



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

 graph No. 39052 ; plate 22, a. 



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 motorcjTle is equipped with a 134-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 tlie ignition system, the timer being advanced 

 and retarded by a small lever at tlie 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 witli 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 crank- 

 case. 



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

 double-reduction sprocket-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 remain at rest when the 

 engine is propelling the machine. 



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

 wheels mount 28-by-li4-ii"ich, single-tube, pneumatic tires, and the 

 complete machine weighs just under 100 pounds.
