<p>Apparatus for connecting an implement (5) to an arm assembly of machinery, the implement (5) having first and second pin support plates (4, 6) each having first opposed apertures (9. 10) and second opposed apertures (11, 13). The apparatus includes a first pin and bush assembly (2) having a pin (28) and two pairs of bushes (32, 34) and (36, 38) for engagement with the pin (28), The pin (28) extends through the first opposed apertures (9, 10) and through eccentric apertures in each pair of bushes (32, 34), (36, 38) with the pair of bushes (32, 34) abutting respective sides of the first pin support plate (4) and the other pair of bushes (36, 38) abutting respective sides of the second pin support plate (6) The first pin and bush assembly (2) is moveable to adjust the spatial separation between the pin (28) and a second pin (40) located between the second opposed apertures (11, 13) and the length of pin (28) between inner bushes (34, 36) is varied to accommodate the dimensions of a pin engagement portion of the arm assembly.</p> |
