  • Patent number: 5621987
    Abstract: An assembly for coupling an implement to an operating arm of a machine generally consisting of a first component fixedly mountable on the implement, having an annular gripping surface, and a second component connectable to the operating arm having a pair of gripping members displaceable along a first line of travel into and out of gripping engagement with the gripping surface of the first component, and am actuator for selectively displacing the gripping members into and out of such gripping engagement, the first component having at least one pair of spaced abutment surfaces disposed in opposed relation to the gripping members for restricting displacement of the gripping members relative to the first component along a second line of travel intersecting the first line of travel and at least one abutment surface engageable by the gripping members for restricting displacement of the gripping members along the first line of travel for retaining at least a portion of the gripping members in opposed relation to the

  • Patent number: 5618157
    Abstract: An assembly for coupling an implement to an operating arm of a machine generally consisting of a first component including a base section fixedly mounted on a wall portion of the implement and an annular flange section disposed on an upper end of the base section, and a second component connectable to the operating arm, including a base section disposable in coupling relation with the first component, a pair of gripping members disposed on the base section and displacable into and out of gripping engagement with the annular flange section of the first component when the components are disposed in coupling relation and an actuator for selectively displacing the gripping members into and out gripping engagement with the annular flange section of the first component, each of the gripping members having a recess for receiving a segment of the annular flange section therein, having an end wall surface engagable with an annular end wall surface segment of the annular flange section, in gripping engagement, and uppe

  • Patent number: 5611158
    Abstract: An assembly for coupling an implement to an operating arm of a machine generally consisting of a first coupling component fixedly mountable on the implement, having a plurality of sets of opposed abutment surfaces spaced circumferentially relative to a given axis thereof and disposed substantially radially relative to such axis, and an axially spaced abutment surface, and a second coupling component disposable in mating relation with the first coupling component, having apparatus for detachably connecting to the operating arm, at least one locking member displaceable between an extended position and an retracted position received between a selected set of the radially disposed, opposed abutment surfaces and the axially spaced abutment surface, when the components are disposed in mating relation, and apparatus for selectively displacing the locking member into the extended and retracted positions.

  • Patent number: 5575093
    Abstract: An assembly for coupling an implement to an operating arm of a machine comprising a first component fixedly mountable on the implement, a second component connectable to the operating arm, one of the components having a slot in a side and bottom thereof, disposed substantially radially relative to a given axis, and the other of the components having a section receivable into the slot to position the components in coupling relation, the components having engageable surfaces permitting angular displacement and precluding axial displacement relative to the given axis when the components are disposed in coupling relation and retaining means disposable in abutting relation relative to the components when disposed in coupled relation for precluding angular displacement between the components relative to the axis.
