The machine now is not as originally constructed, for cer- 

 tain changes were made about two years after the initial trial 

 run. These included the replacement of the 1 -horsepower, 

 2-cycle, Sintz gasoline engine by a 2-horsepower engine; the 

 replacement of the 28-inch cushion-tire wheels with wire- 

 spoked wheels mounting single-tube pneumatic tires 36 

 inches in outside diameter; and the substitution of a tiller- 

 operated, fixed-axle steering mechanism for the original 

 worm-and-gear-driven, swinging front axle of carriage de- 

 sign. The original axle, fixed so as not to swing, was 

 retained for this purpose. 



The vertical, 1 -cylinder, water-cooled engine, with 

 make-and-break ignition, delivered its power by chains to 

 a jackshaft forward of the motor and parallel to the rear 

 axle. A small sprocket at each end of this jackshaft is con- 

 nected by a chain to a larger sprocket on each rear wheel. 

 A spring-loaded, friction-type differential is provided at the 

 left end of the jackshaft. Friction clutches on the jackshaft 

 are operated by a vertical T-rod within reach of the driver 

 and furnish a choice of two forward speeds. Operation of 

 the clutches is by means of a chain, which is actuated by a 

 sprocket on the lower end of the T-rod. A third forward 

 speed of very low ratio is provided by a clutch-and-sprocket 

 device on the right end of the rear axle. This appears to 

 have been abandoned, as no means of operating it remains. 

 No reverse is provided on the car. The engine was cranked 

 through the spokes of the right rear wheel. A hand lever 

 operates a friction band on the end of the jackshaft, for 

 braking. 



The foot-operated accelerator is mounted on the floor- 

 board. A water tank beneath the seat is connected to the 

 engine by two rubber hoses. The gasoline tank is beneath 

 the floor, below the level of the carburetor. Fuel was 

 pumped to the carburetor by a mechanical pump operated 

 by the ignition linkage. 



The chassis consists of a rectangular tubular frame upon 

 which the body rests on long semielliptic springs. The 

 total weight of the vehicle is about 1,000 pounds.
