Abstract
An assembly connectable to a boom of a machine operable to perform material working functions generally consisting of a handle connectable to the boom; a fluid actuated cylinder assembly operatively interconnecting the boom and handle for pivotally displacing the handle relative to the boom; a bucket member connected to the handle for pivotal movement along an arcuate line of travel between uncurled and curled positions; a fluid actuated cylinder assembly operatively interconnecting the handle and the implement for displacing the implement between uncurled and curled positions; a sifting member connected to the handle for pivotal movement along an arcuate path between retracted and extended positions, at least partially overlapping the arcuate path of the implement whereby when the sifting member is in the retracted position, the implement is in the curled position and the sifting member is displaced from the retracted position to the extended position, the sifting member will be caused to engage and displace the implement from the curled to the uncurled position, and a fluid actuated cylinder assembly for pivotally displacing the sifting member between the retracted and extended positions. Control means further is provided to operate the displacing means in causing the sifting member to be disposed in its retracted position, the implement to be displaced to its uncurled position, the implement to be displaced from its uncurled position to its curled position into engagement with the sifting member, the sifting member to be displaced from its retracted position to its extended position thereby displacing the implement to its uncurled position and the sifter to be displaced to its retracted position.
