Implement coupling assembly

An assembly mountable on a machine comprising:

• an implement provided with at least one pair of opposed pin receiving recesses;
• a dipper stick operatively connectable to said machine for selected movements, having a first connecting pin rotatably mounted in an end thereof and receivable in one of said implement recesses;
• at least one support link pivotally connected to said dipper stick;
• at least one actuating link pivotally connected to said support link, having a second connecting pin rotatably mounted therein and receivable in the other of said implement recesses;
• at least one spacer link connected to one of said connecting pins and disposable selectively in an inoperative position detached from said second connecting pin and in an operative position between said first and second connecting pins when said first and second connecting pins are disposed in said recesses, functioning to retain said first and second connecting pins in said recesses;
• and
• a fluid actuated assembly including a cylinder member having a base end pivotally connectable to said dipper stick and a rod member pivotally connected to at least one of said support and actuating links whereby when said spacer link is in said inoperative position, and upon operation of said fluid actuated assembly, said connecting pins will be caused to displace relative to each other along a linear line of travel intersecting the axes thereof to permit said pins to be inserted into and withdrawn from said recesses for correspondingly coupling and uncoupling said implement relative to said dipper stick upon manipulation of said dipper stick.
