Abstract
Abstract An attachment for quick mounting on the bucket of earth working equipment such as back hoes and loaders comprising a pair of spaced, parallel C-shaped plates each having two arms connected by a bight, a bearing bar between said plates and in the space between the arms loosely carried by a turn screw for movement toward one pair of arms to removably clamp the attachment to a bucket, the attachment having transverse holes and rods to removably support alternately useable tools. Tools disclosed are a scraper blade and pneumatic hammer. In an alternate embodiment, the bearing bar is carried by a support bar extending through and captured in an elongate opening in the C-shaped plates, and is engageable by a turn screw carried by a nut between the plates; a locking device is provided including a star-wheel secured to the screw and socket tubes for receiving a locking pin passed between the teeth of the star wheel.
