Patent number: 6938700Abstract: Sweep retaining structure includes a spring wire retainer with a base supported in a groove on the underside of the wedge support which mates with a stem portion of the sweep. The wedge support is apertured, and a central curved portion of the retainer passes through the aperture and supports a sweep-contacting end above the surface of the wedge support. The end is biased toward a contact area on the sweep to engage the area and eliminate sweep loss problems by preventing the sweep from slipping downwardly from the mounted position. To remove the sweep, a tool is inserted through the slot to depress the retainer end, and the sweep is forced off the wedge support. A raised area on the sweep directs soil away from the retainer and contact area to reduce wear and eliminate depression of the end during operation. The underside of the raised area positions the wire end and provides bend-resisting support for the wire.Type: GrantFiled: February 28, 2003Date of Patent: September 6, 2005Assignee: Deere & CompanyInventors: Richard David Zaun, Benoit Poutré , Donald Ray Peck, Mark Beeck, Richard Wayne Hook, James Michael VanAuwelaer, Jarrod Ray Ruckle

Patent number: 4854813Abstract: In the operation of construction vehicles, it is often desirable to quickly change from one work implement to another for various types of work. In order to accomplish this, adapting brackets or extensive support structure is added to the support arm and operating linkage of the vehicle to mount a specifically design work implement. Such designs have been known to alter the function of the operating linkages to a point where the performance of the work implement is sacrificed both in operational force capabilities and capacity. The coupling apparatus of the subject allows a plurality of work implements to be quickly coupled to and uncoupled from a vehicle. The coupling apparatus does so in a manner that maintains the operating geometry of conventional linkages and thereby maintains the appropriate operational forces needed for manipulation of the work implement with very little reduction in capacity from that of a convention work implement.Type: GrantFiled: May 6, 1988Date of Patent: August 8, 1989Assignee: Caterpillar Inc.Inventors: Robert L.
