One of the claims made by Long was for the front-wheel 

 forks to use improved steering heads utilizing small balls 

 such as now have been used for many years on the steering 

 heads of bicycles and motorcycles. Long unfortunately 

 was unable to build such small balls at the time he con- 

 structed his machine, and the tricycle's two steering heads 

 are therefore supplied with plain bushings. 



The rear wheel, 5 feet in diameter, is the driving wheel. 

 The two 3-foot front wheels are mounted in steering forks, 

 the heads of which are connected by a curved tie rod. 

 Spoon brakes operate against each solid front tire. It is 

 obviously intended for two people to operate the vehicle. 

 Steering by means of only one of the handle bars is very 

 difficult, as is operation of both brake levers by one person. 

 Each of the individual seats is mounted on a full-elliptic 

 spring, and is adjustable in height. 



The engine is attached to a steel plate (one of the re- 

 placement parts) mounted in the framework on small 

 rollers so as to be movable backwards and forwards by 

 means of a lever pivoted in front of the seat. On the 

 crankshaft of the engine are two pulleys (fig. 33), the larger 

 of which is splined and movable lengthwise on the shaft. 

 Bringing the engine plate backwards forces one or the 

 other of the driving pulleys into contact with the tire of the 

 rear wheel. As the pulleys are of different diameter, two 

 driving ratios are provided. The boiler and one of the 

 two water tanks are also mounted on the engine plate, 

 necessitating a flexible tube between the fuel tank and the 

 burner beneath the boiler, as well as between the two 

 water tanks. 



In addition to the boiler, the burner, and the engine 

 mounting plate, other replacement parts include the fuel 

 tank, the two water tanks, the gauges, all piping, the hand- 

 operated air pump, and the hand-operated water pump. 

 The latter is, however, from an early steam automobile. 



The machine weighs about 350 pounds, according to its 

 owner, and operates at a steam pressure of approximately 

 100 pounds per square inch.
