Patent number: 6619319Abstract: A non-spill, multi-line fluid connector includes a first part and a second part removably connected to the first part. Each of the first and second parts includes a plurality of fluid channels, each of which connects to a corresponding fluid channel of the other part without fluid spillage. The fluid channels in each part can be arranged concentrically, which enables the parts to be rotated relative to each other while maintaining the fluid connections. One part can be incorporated into a latch pin of a tool coupler, and the other part can be incorporated into a latch bracket attached to a hydraulically operated tool, wherein the latch bracket receives the latch pin to lock the tool to the tool coupler and to establish one or more hydraulic connections to the hydraulic tool. A locking assembly secures together the first part and the second part when fluid pressure is applied.Type: GrantFiled: November 6, 2000Date of Patent: September 16, 2003Assignee: Woods Equipment CompanyInventors: Lee A.

Patent number: 5966850Abstract: The invention provides a coupling assembly and method for coupling a tool to a dipperstick, or arm, on an apparatus which has a hydraulic system for moving the tool. The coupling assembly includes a coupler body having link structure for pivotally coupling to the dipperstick. A latch member is movable between an engaged position for engaging the tool and a disengaged position for disengaging from the tool. A spring is arranged to provide a spring force to urge the latch member to the engaged position. A hydraulic motor has a part that is stationary relative to the coupler body and a movable part that can be extended relative to the stationary part when hydraulic pressure is applied to one end of the hydraulic motor. The movable part is coupled to the latch member such that extension of the movable part urges the latch member to the retracted position in opposition to the spring force.Type: GrantFiled: September 24, 1997Date of Patent: October 19, 1999Assignee: Wain-Roy Holding, Inc.Inventor: Lee A.

Patent number: 5865492Abstract: A hydraulic grapple assembly couples to a link pivot and to a dipper pivot of an arm of an equipment. The assembly includes a grapple having a fixed jaw and a movable jaw. The fixed jaw extends in a direction substantially parallel to an imaginary line drawn between the link pivot and the dipper pivot when the grapple assembly is coupled to the arm. A distal end of the fixed jaw is positioned closer to the link pivot than to the dipper pivot when the grapple is coupled to the arm. The movable jaw has a proximal end coupled to a proximal end of the fixed jaw by an articulation. A hydraulic grapple actuator moves a distal end of the movable jaw between open and closed positions relative to a distal end of the fixed jaw. The grapple assembly can include a hydraulic swinger mechanism that rotates the grapple about an axis that is approximately aligned with the imaginary line through the dipper pivot and the link pivot.Type: GrantFiled: January 7, 1997Date of Patent: February 2, 1999Assignee: WEC CompanyInventor: Lee A.

Patent number: 5727342Abstract: The invention provides a coupling assembly for coupling a tool to a dipperstick, or arm, on an apparatus which has a hydraulic system for moving the tool. The coupling assembly includes a coupler body having a frame that defines a central cavity, and also having link structure for pivotally coupling to the dipperstick. An actuator assembly positioned within the central cavity includes a latch pin that can slide between an engaged position and a retracted position. In the engaged position, an end of the latch pin projects out from a rear end of the frame for engaging a receptacle defined by the tool. In the retracted position, the end of the latch pin does not project out from the frame. A bias structure normally urges the latch pin toward the engaged position with a bias force. A hydraulic latch cylinder has a fixed part and a movable part rigidly coupled to the latch pin such that, when the movable part is extended from the fixed part, the latch pin is urged to the retracted position.Type: GrantFiled: April 18, 1996Date of Patent: March 17, 1998Assignee: Wain-Roy, Inc.Inventor: Lee A.

Patent number: 5634735Abstract: A coupling apparatus for releasably securing a tool to the linkage of a tractor such as a backhoe. The coupling apparatus includes a second coupling element which is fixed to the lower end of the linkage and a first coupling element which is fixed to the upper end of the tool. One of the coupling elements has a generally upwardly facing first engaging surface for engaging a downwardly facing first engaging surface of the other coupling element which provides the main coupling connection between the first and second coupling elements. Each of the first and second coupling elements has a second engaging surface which is spaced from the first engaging surface. When the first and second coupling elements are brought together in a coupling mode, the second engaging surfaces engage and provide a fulcrum about which the linkage pivots relative to the tool.Type: GrantFiled: October 2, 1995Date of Patent: June 3, 1997Assignee: Wain-Roy, Inc.Inventors: Lee A. Horton, Arthur A. Erickson
