DEFINITION

Classification: 267/196

Friction (e.g., "snubber"):

(under subclass 195) Spring device wherein the retarder comprises two friction surfaces which are caused to rub against each other to slow the distortion or recovery of the spring element.

188, Brakes,

129+, for a vehicle friction shock absorber, per se, having a spring biased friction surface, but in which there is no distortion of the spring as the parts move relative to each other.

213, Railway Draft Appliances,

22+, for a cushioned railway draft appliance employing a spring and friction surfaces, and subclasses 220+ for a car end bumper or buffer, per se.
