DEFINITION

Classification: 172/793

(under subclass 792) Apparatus in which one or more of the actuators is operatively connected between the vehicle's frame and the ring or ring portion and effective when operated to bodily move said ring or ring portion from one position of adjustment to another in a substantially lateral direction relative to said vehicle frame.

(1) Note. A scraper is usually provided with lift means at each end whereby it may be angled in a vertical plane. Such lift means may be operated to cause some lateral shifting of

the ring but they are not ring-shifting means of this definition. The actuator of this definition is an added actuator whose principal function is to bodily shift the ring or ring portion laterally.
