Publication number: 20120107080Abstract: A loader mast-to-mounting frame pin arrangement is provided. The pin arrangement has stops added to a shaft that allow the pin to be held in two positions: the locked position and the parked position. In the locked position, a unique slot cut in the mast plate retains the pin by not allowing an eccentric protrusion on the shaft from passing through the slot when the pin is rotated to place the shaft in the top of the slot. When the pin is rotated so the shaft is towards the bottom of the slot, the eccentric protrusion is allowed to pass through the mast plate and the pin can be pulled out until it hits another protrusion on the shaft. At this point, the pin will stay in the mast but the loader can be removed from the tractor. To prevent the pin from rotating by itself, when in the locked position, and the loader coming unlatched, a spring loaded knob engages in the slot which prevents the shaft from being able to rotate to the unlocked position.Type: ApplicationFiled: October 29, 2010Publication date: May 3, 2012Inventors: Tyler Eugene Hilsden, Scott Robert Jamieson, Henry Friesen

Patent number: 7882898Abstract: A quick coupler includes mounting structure for mounting the coupler to a machine, and for mounting the coupler to an implement. The mounting structure on the coupler includes wedge coupling surfaces and a tube. The mounting structure on the implement includes hooks for engaging the tube, and complementary wedge coupling surfaces. The wedge coupling surfaces wedge together during coupling to produce and tight fit and solid hold between the coupler and implement. The mounting structure is robust, and can accommodate future possible wear. The kinematic impact on the performance of the implement due to the use of the quick coupler is minimized.Type: GrantFiled: August 26, 2010Date of Patent: February 8, 2011Assignee: Caterpillar Inc.Inventors: Andrew L. Vering, Karl E. Lindenmuth, Richard K. Oswald

Patent number: 7866935Abstract: A coupler for use with an excavator provides a hook with a mouth which receives a cross bar of an implement such as a bucket at an upper end. Towards a bottom end the coupler receives an extension through an opening. The extension is then retained by a pin through a bore in the extension and a bore in a body of the coupler. The mouth of the hook is provided with at least one wear pad which preferably extends along a substantial width of the mouth and is provided with adjustment members which can extend the wear pad into the mouth incrementally and/or to be tensioned against a cross bar with a selected amount of tension.Type: GrantFiled: December 11, 2008Date of Patent: January 11, 2011Assignee: TAG Manufacturing, Inc.Inventors: Albert T. Wilt, Trace Errera, Alan Graham, Al Kimble

Patent number: 7861642Abstract: A valve block disposed adjacent a tool attachment of a working machine, where the tool attachment is adapted for connection to different types of hydraulically maneuvered tools or implements with the aid of a hydraulically actuated locking device. The valve block includes first port means, second port means, and third port means for connecting hydraulic lines of the working machine to hydraulic coupling elements and to the locking device respectively. The valve block includes a line system and valve means which communicate with the port means so as to fulfill at least three of the following five functions: ensuring the presence of pressure in the locking device in the event of a fracture in the hydraulic lines of the working machine; ensuring connection of the first port means with either the second port means or the third port means to obtain post-tensioning of the locking device to relieve the pressure load; and to provide pressure limitation.Type: GrantFiled: November 3, 2008Date of Patent: January 4, 2011Assignee: Oilquick ABInventor: Ake Sonerud

Patent number: 7836616Abstract: A loader coupler includes left and right inner rib mounts that mate with left and right ribs of a first type of attachment coupling structure. The coupler also includes left and right outer rib mounts that mate with left and right ribs of a second type of attachment coupling structure. Left and right plunger assemblies each move between a locked and unlocked position and each includes both a first lock plunger and a second lock plunger. The left and right first lock plungers extend into left and right inner locking regions when the left and right plunger assemblies are located in the locked position. The left and right second lock plungers extend into left and right outer locking regions when the left and right plunger assemblies are located in the locked position.Type: GrantFiled: November 7, 2007Date of Patent: November 23, 2010Assignee: Attachment Technologies, Inc.Inventors: Timothy C. Esser, Ray S. Fatemi

Patent number: 7832130Abstract: A mounting bracket is designed to interchangeably connect a processor attachment to the stick of a larger excavator or the boom of a smaller excavator in place of the stick. The mounting bracket includes mounting assemblies that are designed to operatively attach the bracket to the stick and related bucket cylinder linkage assembly of a larger excavator. The mounting bracket also includes mounting assemblies that are designed to operatively attach the bracket to the boom and related stick cylinder of a smaller excavator. The mounting bracket may avoid the need to obtain and maintain plural mounting brackets for different mounting applications (e.g., stick or boom).Type: GrantFiled: October 6, 2006Date of Patent: November 16, 2010Assignee: The Stanley WorksInventors: Clayton Sederberg, Matthew G.

Patent number: RE44771Abstract: A rear-mounted implement mounting system includes semicylindrical seats open upwardly and mounted on a lower back portion of a utility vehicle chassis that receive bar members located on a facing lower part of the rear-mounted implement. The utility vehicle chassis further includes semicylindrical receivers open in a rearward direction and adjacent cylinder portions open laterally. The receivers guide cylindrical bosses, located on an upper portion of the rear-mounted implement, into alignment with the cylinder portions, when the rear-mounted implement is pivoted upwardly by extending the boom cylinder of the rear-mounted implement. Connecting pins can be slipped through the cylindrical bosses and cylinder portions to lock the rear-mounted implement to the utility vehicle chassis. An operator remaining in the vehicle cab or operator station can easily operate the mounting system.Type: GrantFiled: April 10, 2006Date of Patent: February 25, 2014Assignee: Deere & CompanyInventors: David Laverne Sprinkle, Judith Fuzzen
