ARRANGEMENT OF GEARING a six-cylinder gasoline engine is analogous in many ways tothe valve motion of a steam locomotive. The idea in thevalve motion of the motor-car gasoline engine is to operatethe valves to produce as nearly as possible uniform horse-power by these cylinders at various speeds. The throwing on or off of the friction-clutch is the onlymove necessary to vary the speed of the car. Even thoughthe car reduces to a speed of 2 or 3 miles an hour simplyby throwing in the clutch, the load will be assumed andcared for by the engine without the bucking often expe-rienced with automobiles and other constant-speed throwing on or off of the clutch is actuated by air,controlled by an operating valve, the lever of which issmall and in the hands of the operator. Plence it is easyfor him to keep his head out of the window, watch thebrakeman, the movements of the car and handle the gaso-line-engine mechanism. The expense for fuel, repairs, cl
