WINTON GASOLINE AUTOMOBILE, 1903 

 Gift of H. Nelson Jackson in 1944 (USNM 312831) 



The first trip from coast to coast across the continent in 

 an automobile was made in 1903 by H. Nelson Jackson 

 driving this Winton, assisted by Sewall K. Crocker (fig. 

 22). The trip, from San Francisco, Calif, to New York 

 City, occupied 63 days, only 44 of which were used in 

 traveling. The car, purchased secondhand in San Fran- 

 cisco by Jackson, left that city on May 23 and reached 

 New York on July 26 after having traveled over roads and 

 trails that would be impassable for the modern, low-slung 

 passenger automobile. 



The water-cooled engine is of the 2-cylinder, 4-cycle, 

 horizontal-opposed type located near the center of the 

 frame, beneath the left seat. The bore is 5V4 inches, and 

 the stroke 6 inches. The flywheel is located in about the 

 center of the vehicle; it rotated in a vertical plane parallel 

 with the sides of the frame. It is 24 inches in diameter, 

 with a rim 2V2 inches thick and 3V2 inches wide. The en- 

 gine is suspended in place from two chassis cross members. 



Each cylinder is fitted with a carburetor, one of the 

 earliest instances of multiple carburetion on a standard- 

 production machine. An exhaust pipe leads from each 

 cylinder to a common muffler, the latter equipped with a 

 cut-out operated by a small lever in front of the driver's 

 seat. On the left side of the engine is an enclosed train of 

 gears which drives the two exhaust camshafts, the water 

 pump, and the ignition timer. The timing-gear cover is of 

 aluminum. 



The water system includes the water jackets on the two 

 cylinders, the centrifugal pump of aluminum, a radiator, 

 and a water-storage tank, together with the necessary pip- 

 ing. The radiator, composed of horizontal tubing fitted 

 with radiating disks, is placed in the front of the car and 

 behind an opening in the wooden hood fitted to the body 

 at the front. 



Behind the radiator is a cylindrical tank made of two 

 separate sections, the left one for water. A filler cap is 

 provided at the top of the tank, while an overflow pipe is 

 located within the tank. A pipe from the water jackets at
