engine is placed almost horizontally beneath the carriage 

 body, with its cylinder head extending backward and 

 above the rear axle. The engine, transmission, and differ- 

 ential are mounted in a frame supported by the dead rear 

 axle and also at the center of the front axle. 



Power was transmitted through bevel gears from the ver- 

 tical crankshaft to a main horizontal shaft and thence by- 

 spur gears to a parallel jackshaft, at each end of which 

 was a small combination sprocket. The differential is 

 built into this jackshaft. Chains formerly connected the 

 jackshaft sprockets with large sprockets attached to the 

 inside of the wooden spokes of the carriage-type rear 

 wheels. These wheels are 44 Vi inches in diameter and 

 have iron tires. 



On the main shaft are three friction clutches, two for the 

 two forward speeds and one for the reverse. These 

 clutches were operated through cable connections by an up 

 or down movement of the steering tiller. The steering 

 knuckles on the front wheels are of the C type, the pivot 

 axis of each intercepting the plane of its wheel at the 

 ground. The front wheels are also of the wooden-spoked 

 carriage type, with iron tires 38 V^ inches in diameter. 



The hand starting crank, projecting at the rear of the 

 car (fig. 36), turned the crankshaft by means of a pair of 

 bevel gears which automatically unmeshed when the en- 

 gine started. A floatless, constant-level jet carburetor 

 received gasoline from a supply tank located above the 

 carburetor and to the left of the engine. The supply was 

 regulated by a needle valve to flow at the rate required to 

 produce the desired power and speed. At slower engine 

 speeds excess fuel overflowed into a tank below the car- 

 buretor, from which it was returned to the main supply 

 tank by means of a hand pump. Ignition was obtained 

 by a make-and-break electric igniter actuated by a 

 projection on the piston head. The water tank is located 

 to the right of the engine.
