DEFINITION

Classification: 171/86

(under subclass 84) Apparatus in which the separating digger is provided with a mounted member having a bearing surface to hold the digger from movement with respect to said mounting member to provide (1) a motion which directly causes the separation of an object from the earth and/or (2) a movement which causes a discharge or unloading of objects already collected on or by the separating digger.

(1) Note. Mere adjustably supported separating diggers have been excluded and classified on the basis of other pertinent details of the digger.

(2) Note. The separating digger may be manually actuated, power operated by a motor or traction drive or mounted so that it is freely movable.

(3) Note. Pivotally-supported separating diggers are included where the digger is adapted to swing up and discharge recovered objects collected on the digger to thus complete the digging operation.

SEE OR SEARCH THIS CLASS, SUBCLASS:

44, for power means to optionally shift a separating digger to dig, discharge or adjust the digger.

71+, for vibrating separating surfaces which are disposed rearwardly of and adjoining or contiguous to a leading plow or earth cutting blade. 141, for lifting or tilting means for adjusting unearthing apparatus.
