Publication number: 20090056174Abstract: Soil is captured into a bowl attached to a frame of a scraper machine by maneuvering the machine while a cutting bit attached to the bowl slices through the underlying soil. The bowl is supported on the frame, and the soil cutting is accomplished via a spade bit attached to the bowl at a cut opening. The spade bit has a cutting edge with a forward protrusion flanked by swept back segments. A top surface of the spade bit may be contoured with a central ridge flanked by a twist contour surface to urge soil towards opposite sides of the bowl.Type: ApplicationFiled: August 29, 2007Publication date: March 5, 2009Inventor: Thomas Congdon

Publication number: 20080301980Abstract: Apparatus for moving associated material which includes a mounting and a blade carried on the mounting, the blade having an edge for engaging a quantity of material to be moved, the edge having a bead extending along the edge, the bead having a cross-section that has a curvilinear contour whereby the blade will be deflected away from interfering obstacles within the associated material. In some embodiments the apparatus may be a shovel. In some of these embodiments, the bead has a circular cross-section. Some embodiments have the circular cross-section and others have a curvilinear cross-section. The invention also includes the method for moving material which includes providing a mounting and providing a blade carried on the mounting that has an edge for engaging a quantity of material to be moved, providing an bead extending along the edge that has a cross-section that has a curvilinear contour whereby the blade will be deflected away from interfering obstacles within the associated material.Type: ApplicationFiled: June 5, 2007Publication date: December 11, 2008Inventor: JESSE E.

Patent number: 7266914Abstract: A bucket assembly is provided with a kit that includes a base plate for permanent connection to a lower part of the bucket, and sacrificial, impermanent replaceable wear edge segments for the forward lip and corner leading edges of an excavator or loader bucket. These segments form a set of “bolt on” cast wear members and wing wear segments. The base plate and wear plates are drilled and machined to accommodate the precision fitting bolting on of the replaceable lips and cast wing segments. The cast lip segments are of both left and right hand configurations and come in a variety of widths that, in combination, may tend to fit a large number of different commercially available bucket sizes. The lip top and bottom faces are shaped in a profile that may tend to result in relatively uniform wear and a reduction in friction when digging into various materials.Type: GrantFiled: December 28, 2004Date of Patent: September 11, 2007Assignee: Peninsula Alloy Inc.Inventor: James Grant
