Abstract
A coupler is provided for implementation on the boom of an excavator and adapted for receiving and coupling an arm or implement. The coupler is pinned to the boom through apertures and a pair of parallel plates. An actuating hydraulic piston is connected to the coupler through holes passing through another pair of plates. Attachment to the arm or implement is achieved by first engagement of a pair of slots with pins on the arm, and subsequent engagement of other slots with another pair of pins. The last mentioned slots have associated therewith a cam locking plate which closes the slot upon the pins to prevent removal.
