Patent number: 4624038Abstract: A heat treatable aluminum base alloy is cast in a permanent mold to form an annular preform having an annular disc portion projecting inwardly from first and second annular wing portions extending axially in opposite directions from the disc portion. The preform is mounted on rotatable mandrels having peripheral surfaces spaced inwardly from the corresponding wing portions, and a forming roller presses each wing portion inwardly against the corresponding mandrel surface while the mandrels and preform are rotating to shear-form each wing portion into a substantially thinner and wider rim portion conforming to the contour of the corresponding mandrel surface. In one embodiment, the disc portion of the preform is engaged by a forming roller and a pressure roller both of which move radially inwardly while the disc portion and adjacent mandrel are rotating to shear-form the disc portion inwardly into a thinner and radially wider disc portion.Type: GrantFiled: September 16, 1983Date of Patent: November 25, 1986Inventor: William D. Walther

Patent number: 4327922Abstract: Reusable seal assemblies for heavy duty truck or semi-trailer wheels and axle assemblies. The reusable seal assemblies have an outer metal hub engaging shell formed with an outer generally axial surface which forms a clearance fit with the corresponding seal-receiving surface of the hub. The seals further have an axle engaging inner sheet metal shell formed with an inner surface which forms a clearance fit with the axle spindle. Each of the inner and outer shells are formed with annular recesses. These recesses are proportioned to receive square-cut static sealing rings. In one embodiment the annular recess formed in the outer shell may be provided with a radial inner portion which is tapered with respect to the adjacent surface of the hub, so that when an elastomer seal is received within the annular recess, the compression of the static seal between the recess and the hub causes the seal assembly to be biased inwardly into a seated position within the hub.Type: GrantFiled: June 25, 1980Date of Patent: May 4, 1982Assignee: Dayton-Walther CorporationInventor: William D. Walther

The inner legs are formed with vertical inwardly indented corrugations formed in the end and side walls thereof for added strength. In another embodiment, the outer leg is also formed with corrugations which interfit within the corrugations formed in the inner leg.Type: GrantFiled: December 10, 1979Date of Patent: December 29, 1981Assignee: Dayton-Walther CorporationInventors: William D.

Patent number: 4124225Abstract: A sandshoe for a semi-trailer landing gear is formed with an inverted V-shaped support member, the depending legs of which are attached to a bottom platform. The apex of the support member is received within a generally conforming, transversely oriented yoke carried on the bottom of the landing gear, and is attached thereto by bolts as well as by auxiliary retainer clips. The improved sandshoe is relatively light in weight yet provides high strength as compared to conventional sandshoes, in that the arrangement of the support member places the bottom platform in tension in the region between the legs of the support member.Type: GrantFiled: October 14, 1977Date of Patent: November 7, 1978Assignee: Dayton-Walther CorporationInventors: Vicente M. Lozada, William D. Walther, Lawrence J. Welp
