while sitting in the car. A sprocket on the shaft upon 

 which the crank is mounted is connected by a chain to a 

 sprocket on the engine crankshaft. An overrunning clutch 

 is incorporated within the hub of the latter sprocket so that 

 the engine will not drive the crank handle once the engine 

 has been started. 



The 2-speed forward and 1 -speed reverse transmission is 

 of the planetary type. The reverse and the low speed for- 

 ward are operated by band and drum clutches, and the 

 high speed by a friction compression clutch. A single shaft 

 carrying three eccentrics, with the three throws in different 

 directions, serves to actuate each of the three clutches in- 

 dividually by tightening bands around the drums for the 

 two lower speeds, and through a bell crank moving in a 

 direction longitudinal to the main shaft for the high speed. 

 A vertical extension of the eccentric shaft is located to the 

 right of the driver, to be operated by his right hand, full 

 forward position of the lever engaging the high-speed 

 clutch. 



A brake pedal is connected to an external contracting 

 band on a brake drum located on the transmission shaft 

 between the low-speed and reverse drums. 



A sprocket on the transmission, between the reverse 

 drum and the brake drum, is connected by chain to the 

 differential unit on the rear axle. Located on the differ- 

 ential unit is a brake drum. The band of this brake is 

 actuated by a hand lever adjacent to the gear shift and 

 spark levers. 



The rear-axle housing is tubular and is strengthened by 

 a truss rod running beneath it. The tubular front axle, 

 likewise strengthened with a truss rod, is equipped with 

 pivoted steering spindles at each end, and the two are con- 

 nected by a tie rod. Between the steering-tiller post and 

 the arm to the center of the tie rod is a full-elliptic spring, 

 which turns as the tiller is turned and prevents road shock 

 from reaching the tiller. 



Wooden-spoked artillery wheels, mounting 28-by-3-inch 

 clincher tires, are used. The front wheels are supported 

 on tapered roller bearings, and the rear wheels are on 

 straight roller bearings. Grease cups provided lubrication 

 for the rear wheel bearings.
