ABSTRACT:
An attachment for power operated buckets, in the form of a forked type implement, is shown as supported on the leading edge of the bucket. The implement is suspended, through the provision of intermediate slot forming components, on the leading edge of the bucket by cantilever principles involving a rear portion which bears against the bottom wall of the bucket and a work load supported forwardly of the slot forming components. Hinge components are utilized for attaching the rear portion to the back wall structure of the bucket.
The hinges serve to maintain the leading edge in the groove and have hinge plates that are manipulatable between the horizontal and upright positions so that attachment to the back wall can be realized in the upright position and insertion and withdrawal of the leading edge from the groove accomplished in the horizontal position. Adjustable features for the hinges are shown so that attachment of the implement to different types of buckets may be accomplished.
