sprocket of the engine with the driving sprocket of the differential. 

 A contracting brake band on the differential is controlled by a pedal 

 at the driver's right foot. A small hand lever by the driver's right 

 leg is used to alter the position of the reversing links of the valve 

 mechanism. 



The body, a two-seater, is supported on the running gear by four 

 full-elliptic prings, one at each corner of the body. Behind the seat 

 is a horizontal tube, which leads down from its center to the fire box 

 of the burner and serves as a chimney. The engine and boiler are 

 beneath the seat, while the water tank is under the rear deck of the 

 body. On the rear deck is a large wicker basket for carrying small 

 items. Built in the rear of the body is a tool compartment with a 

 hinged access cover at the back. A buggy -type top, two kerosene head 

 lamps, and a kerosene tail lamp complete the equipment. 



FRANKLIN GASOLINE AUTOMOBILE, 1902 



U. S. N, M. No. 311195; original; from the H. H. Franklin Manufacturing Co. 

 in 1937 ; photograph No. 37687 ; plate 17, a. 



According to a statement from H. H. Franklin, this is the third 

 Franklin automobile built and the first one sold, two earlier cars hav- 

 ing been retained by the factory for experimental purposes. Mr. 

 Franklin states that it was sold originally for $1,250 to S. G. Averell, 

 of Ogdensburg, N. Y., and was bought back by Mr. Franklin in June 

 1916. 



The angle-iron frame of the car has a 71-inch wheel base and carries 

 a 2-seated body of wood with leather upholstery. The air-cooled en- 

 gine is mounted transversely at the front of the frame. Front axle and 

 rear-axle housing are tubular, with the rear-axle housing connected by 

 stay rods to a center cross member of the frame. Four full-elliptic 

 springs are used for the two axles. The wheels are wire-spoked, but 

 the rims are not original, now mounting 30-by-3-inch clincher tires 

 instead of 28-by-3-inch tires. 



The exposed differential at the left of the center of the rear-axle 

 housing is connected by a long chain to the planetary transmission at 

 the left end of the engine. The brake pedal at the right actuates an 

 external contracting band on the brake drum of the differential unit. 

 Two large grease cups supply lubrication to the two rear- wheel bear- 

 ings in the ends of the rear-axle housing. 



The car is right-hand drive and is equipped with a steering wheel. 

 A drag link crosses from the steering-gear box to the left steering 

 knuckle. Two levers are supported on the column below the steering 

 wheel. The right one is for spark control, and the left is for the car- 

 buretor throttle located in the vertical part of the intake manifold a
