Steering Gear.—Fig. 21 shows an approved form of construction for the gear, which converts the rotating motion to a direct line movement. In this the hollow supporting column A, is firmly fixed to a base B.
The shaft C which passes through the column, has a worm D at its lower end, and is journaled in a base E, which carries a cross shaft F, in which is mounted the worm wheel G. One end of the shaft F has an arm H for moving the arms of the wheel knuckles.
Within the tubular shaft C, is a tubular shaft I, for the throttle lever to operate, the lower end of which has an arm J, and within the shaft I, is a shaft K for the sparking lever, the lower end having an arm L.
In the best cars all these parts are made adjustable, so as to provide for wear. In examining or selecting a car, this is one of the points to note.
Fig. 22. Type of Front Axle.
Front Axle.—Fig. 22 shows a common form of front axle, with knuckles and cross connecting rod A, the latter providing means, by the nuts B C, for alineing the wheels.
The Brakes.—These are made in two types, one which is usually in the form of a contracting band, and the other which expands.
All cars are now equipped with two braking systems, one being the service, or running brake, and the other the emergency brake. These brakes are all of the drum type, and are either expanding, or contracting bands tightening against the drums.
