Abstract:
An assembly connectable to a boom of a machine operable in performing a material working function comprising:a handle connectable to said boom;first means connectable to said boom and connected to said handle for angularly displacing said handle relative to said boom;an implement connected to said handle for angular displacement along an arcuate line of travel between uncurled and curled positions;second means operatively interconnecting said handle and said implement for angularly displacing said implement between said uncurled and curled positions;a sifting member connected to said handle for angular displacement along an arcuate line of travel between retracted and extended positions, at least partially overlapping the arcuate line of travel of said implement whereby when said sifting member is in said retracted position, said implement is in said curled position and when said sifting member is angularly displaced from said retracted position to said extended position, said sifting member will be caused to engage and angularly displace said implement from said curled position to said uncurled position;third means operatively interconnecting said handle and said sifting member for pivotally displacing said sifting member between said retracted and extended positions; andcontrol means operatively connected to said second and third displacing means operable to displace said sifting member to said retracted position, displace said implement to said uncurled position, displace said implement from said uncurled position to said curled position into engagement with said sifting member, displacing said sifting member from said retracted position to said extended position thereby displacing said implement from said curled to said uncurled position and displacing said sifting member to said retracted position.
