  • Coupler assembly between a prime mover and a work implement
    Patent number: 4963071
    Abstract: A coupling assembly (10) for demountably attaching a work implement (15) to a prime mover (13). The prime mover (13) has a lifting mechanism (18, 118) and a tilting mechanism (23, 123). The coupling assembly (10) includes a master coupling element (11, 111) adapted to be mounted on the lifting and tilting mechanisms (19 and 20) of the prime mover (13) and an implement coupling element (12, 112) adapted to be atached to the work implement (15). The master coupling element (11, 111) has a frame (25, 125) with upper and lower transverse beam members (26 and 31 or 126 and 131). An aligning horn (28, 128) extends upwardly from the frame (25, 125) of the master coupling element (11, 111). A first, forwardly directed bearing surface (60, 160) extends along the upper transverse beam member (26, 126), and a second, forwardly directed bearing surface (61, 161) extends along said lower transverse beam member (31, 131).
