Ignition of the engine was by spark plug and high-ten- 

 sion coil. Spark advance and retard were performed by 

 means of a short lever in a slot to the right of the driver. 

 The coil is contained in a compartment in the left front of 

 the body. The dry cells are located in a box suspended 

 beneath the left end of the front floorboard. Engine speed 

 was controlled by a lever, working on a segment beneath 

 the steering wheel, which controlled the amount of open- 

 ing of the mechanically operated inlet valve. The exhaust 

 valve leads into a short pipe, which, in turn, leads into a 

 sheet-metal muffler beneath the right rear of the body. 



A centrifugal pump circulated the water through the 

 jackets of the cylinder and through the water tank and the 

 radiator. The latter is composed of a long, seamless, cop- 

 per tube five-eighths of an inch in outside diameter over 

 which are slipped hundreds of copper radiating disks 

 spaced three-eighths of an inch apart. The tube is bent 

 and shaped so that it forms a unit six tubes in height by 

 two tubes in depth, the tubes all lying horizontally. The 

 water tank is contained in a compartment in the right 

 front of the body, and the system is filled through a pipe 

 beneath the left front seat. 



The planetary transmission, with steel pinions and 

 bronze gears, provides two speeds forward and one reverse. 

 Low speed is engaged by depressing a pedal, high speed 

 by moving forward a long lever at the right of the driver, 

 and reverse by moving the lever rearward. Neutral is the 

 central position of the lever. 



Power was transmitted by a single chain to a differential 

 in the center of the divided rear axle. Brake drums are 

 attached to the two halves of the axle, adjacent to the dif- 

 ferential. The two contracting brake bands are simul- 

 taneously actuated by a spring-returned pedal now 

 equipped with a nonoriginal ratchet-and-pawl device. 

 This holds the pedal locked in the depressed position so 

 that it can be used as a parking brake. 



Steering is accomplished through a rack and gear 

 mounted at the base of the steering column and connected 

 by a drag link to the left front-wheel steering knuckle. 

 The rack and gear are adjustable for wear. The two 

 steering knuckles are connected by a tie rod.
