The overflow gasoline tank with the hand pump can be seen in ihe rear. assembly. The clutch assemblies are of Frank Duryea's design, having internal arms, expanding outward to press leather-faced shoes against the inner surface of the drum, thus securing the drum and its gear to the shaft. Behind this machinery is the with its small differential on the right, two laminated rawhide gears meshing with the iron gears of the countershaft, and the internal-gear sprockets hanging on the small pinions at either vnd. 33 Frank Duryea, in a recorded interview in tl • I s National Museum on Novembei 6, 1957, said that he believed these I I'll purchased hem Rochester Rawhide ( 1 mpam A sliding earn bar. mounted nearly in the position of the former shipper-fork carriage, is operated by the vertical movemenl of the tiller handle to engage any one of the three clutches. With the tiller depressed, the vehicle is in reverse. Elevating it slightly puis it into low gear, and raising it still higher runs the machine .it its highest speed.
