AUTOCAR GASOLINE TRUCKS, 1921 

 Gift of the Autocar Co. in 1 922 (USNM 307255 and 307256) 



These one-quarter-size models represent the type 

 XXVI-B (fig. 99) and XXVI-Y (fig. 100) Autocar trucks 

 of 1921. Except for the wheelbase and the type of body, 

 the two types are identical. The former has a 156-inch 

 wheelbase and a unit construction rack body, while the lat- 

 ter has a 120-inch wheelbase 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 con- 

 cealed electric motors. Otherwise the models are inopera- 

 tive. 



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

 of channel 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 adjust- 

 able, tapered, roller bearings. The front tires, of solid 

 rubber, are 34 by 5 inches.
