DEFINITION

Classification: 414/533

Roller connected to support pivotally mounted on vehicle base:

(under subclass 532) Apparatus wherein a roller or plurality

of rollers are attached to a support which pivots relative to the main frame or other base member of a vehicle.

(1) Note. This subclass does not include a roller or plurality of rollers carried by a trailer support frame which turns about the wheel axle of the trailer, unless the roller or rollers are connected to a separate support that pivots relative to said trailer support frame.

(2) Note. Included here is a roller mounted on a shaft having eccentric trunnions at its ends, the shaft thus being swingable relative to bearings in which the trunnions are supported.
