Implement coupling assembly for excavating machines and the like

An assembly mountable on a machine comprising:

• an implement provided with at least one pair of 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 including a pair of segments pivotally connected together and angularly displaceable relative to each other between retracted, inoperative positions and extended, operative positions, one of said segments being secured to one of said connecting pins and the other of said segments being secured to the other of said connecting pins and having means mountable thereon and cooperable with said one segment when said segments are disposed in said extended, operative positions for releasably securing said segments in said extended, operative positions;
• and
• a fluid actuated assembly operatively interconnecting said dipper stick and one of said support link and said actuating link wherein upon operation of said actuating assembly, said link segments will be caused to be displaced between said retracted, inoperative and extended, operative positions, and said connecting pins correspondingly will be caused to be displace relative to each other to be inserted into and withdrawn from said implement recesses for correspondingly coupling and uncoupling said implement relative to said dipper stick upon manipulation of said dipper stick.
