ROAD SHOCKS

SPRINGS AND ABSORBERS.

Shock absorbers are of three-types, broadly speaking, hydraulic, ‘those which impose a frictional resistance to the action of the spring from the moment the first shock is imparted to the wheels, and those which permit the first shock to be taken by a flexible spring, but set up a resistance to the rebound and damp out the bourelr.g or quivering action of the wheel and spring. The first-named type, I.ydrhulic shock absorbers. have some strong supporters, many'motor-* its considering them absolutely l the most effective and generally .the best type; the opposite opinion is expressed by ethers, however, who consider they are not swift enough, in their action to be really effective. The double action friction type is very popular, and consists usually of two arms joined at one end, the joint being flat and considerably larger than the arms. They can be moved, stiffly at the joint, and the opposite ends are fastened one to the chassis frame, the other to the axle. As they become more free in their actions owing to wear, they may be readjusted by a nut and star-shaped spring washer. The third type consists of a stiff circular coiled spring in a case, with a strong strap riveted to the spring and attached to the .axle# of the car by a clip. The case - with , the coiled spring is attached to .the chassis.
