batteries, but it is not known now where or if the instrument was 

 permanently connected to the car. 



The enclosed body seats four persons, two in the rear and two on 

 individual seats in front. The head room is a few inches less than 

 5 feet. There is one door on each side, and each door is fitted with a 

 window which can be raised and lowered. Cylinder locks enable the 

 doors to be locked from the outside, while thumb screws on the inside 

 lock the door handles. Two other windows on each side are fixed in 

 place, but the front windshield and the rear window can be raised and 

 lowered. All eight windows are fitted with roller shades, and a 

 glass visor is located in front of the windshield. 



Within the front battery compartment are 30 storage batteries of 

 one cell each, while 15 are located in the rear compartment. Hinged 

 covers are provided for the two compartments. Fenders and running 

 boards are fitted to the body. 



Electric headlights, side lamps, and taillight are supplied. A Stew- 

 art-Warner speedometer is placed inside the body within view of the 

 driver. Interior illumination and a flower vase complete the 

 equipment. 



AUTOCAR GASOLINE TRUCKS, 1921 



U. S. N. M. Nos. 307255 and 307256 ; one-quarter-size models ; gift of the Autocar 

 Co. in 1922 ; photograph Nos. 38425 and 38425-A ; plate 14, a and ft. 



These models represent the type XXVI-B and XXVI-Y Autocar 

 trucks of 1921. Except for the wheel base and the type of body, the 

 two types are identical. The former has a 156-inch wheel base and a 

 unit construction rack body, while the latter has a 120-inch wheel 

 base and a rotary dump body with power hoist. 



The wheels of the larger model and the dumping action of the dump 

 body truck were originally operated by concealed electric motors. 

 Otherwise the models are inoperative. 



The frame of the full-sized vehicle is made of pressed steel of chan- 

 nel section and is fitted with cross members and braces. All four 

 springs are of the semielliptic type. The tread is 63 inches. The 

 front axle is drop-forged steel of I-beam section. The front wheels 

 are mounted on adjustable, tapered, roller bearings. The front tires, 

 of solid rubber, are 34 by 5 inches. 



The rear axle is of the full-floating, double-reduction, gear-driven 

 type, the gear reduction being compounded through bevel and spur 

 gears. This construction allows low reduction without the sacrifice 

 of road clearance. It also reduces the angularity of the propeller 

 shaft, giving straight lines for the transmission of power. All the 

 gears in the rear axle are of heat-treated steel carried on adjustable.
