An aluminum centrifugal water pump is secured beneath 

 each engine. Each is now in a damaged condition. The 

 pumps are connected by a shaft, and the front pump is 

 driven by a shaft extending back from the aluminum cover 

 provided for the timing gears at the front of the engine. The 

 water jackets of the two blocks are formed of sheet alumi- 

 num, while the water manifolds are aluminum castings. A 

 water tank, of sheet brass, is integral with the top water 

 jacket of the front cylinders. It contains the filler cap and 

 an overflow pipe for the entire water system. 



The radiator, placed low at the extreme front of the car, 

 consists of 42 horizontal tubes arranged across the front, six 

 rows deep and seven rows high, each tube carrying dozens 

 of cooling disks. The adjacent ends of the tubes are con- 

 nected by cast aluminum header plates on each side of the 

 radiator. The cooling water passed from the top water 

 jackets of the cylinders into the water tank, then to the upper 

 right portion of the radiator, and from the lower left of the 

 radiator back to the two pumps. The pumps discharged 

 into the bottom water jackets of the cylinders. 



The low-tension ignition timer was advanced and retarded 

 by a small lever at the driver's seat, but a connecting link 

 is now missing. It is not known now where the battery was 

 located, but the eight coils were secured to the inside of the 

 body above the rear crankcase. Only four incomplete 

 coils now remain in place. A threaded spark-plug hole is 

 provided in the center of each cylinder head. 



The frame of the car consists of two wooden rails 2 inches 

 thick and 3 ! /2 inches high, rigidly secured by the two en- 

 gines; and of two wooden cross members, one at the front 

 and one at the rear. 



The rear-axle gearing is completely enclosed within a 

 bronze housing, and the axle shafts are within tubular steel 

 housings. The bevel gears and the differential ran in lubri- 

 cant. The gear ratio is approximately 1V4 to 1. A divided 

 truss rod beneath the differential housing helps support it. 

 Semielliptic springs, with full shackles at each end, attach 

 the axle housing to the frame. Radius rods at each side 

 connect the housing to the sides of the frame, while two par- 

 allel torque arms connect the housing to the rear chassis 

 cross member. Three grease cups are fitted to the differen-
