Patent number: 5891266Abstract: A method and system for cutting hub bores in metal railroad wheels is disclosed. The system includes a lead and second torch for cutting the hub bores. In the method, the lead torch is moved to an initial position above the wheel. The lead torch is energized and moved to cut through a part of the wheel. The second torch is moved to an initial position above the wheel. The second torch is then energized and moved to cut through a part of the wheel. The entire hub bore is cut in the wheel. Additional torches may also be provided. A gantry system for supporting the lead and second torches is disclosed. The gantry system includes lead and second linear movement means arranged parallel to each other and a third linear movement means perpendicular to the lead and second linear movement means. The gantry system also includes a lead torch carriage means for supporting the lead torch and a second torch carriage means for supporting the second torch.Type: GrantFiled: December 29, 1997Date of Patent: April 6, 1999Assignee: Amsted Industries IncorporatedInventors: Neil E. Konrardy, C. Dale Christie, Daniel H. Gray, Brian L. VanLaar

Patent number: 5333926Abstract: A steel railway wheel with reduced axial flange deflection and reduced, thermally-induced, residual-tensile stress in the wheel rim, has a clearly defined relationship among the plate angle, the maximum depth of curvature of the wheel plate segment, the location of the maximum depth of curvature, the wheel hub and the rim, which relationship is provided for plate segments both concave and convex with respect to the wheel outboard surface.Type: GrantFiled: March 23, 1993Date of Patent: August 2, 1994Assignee: AMSTED Industries IncorporatedInventors: C. Dale Christie, Michael T. Gallagher, Michael J. Hendricksen, John D. Oliver, Mark A. Polzin

Patent number: 5319892Abstract: A method for grinding cast steel railroad wheels is provided. The apparatus comprises a railroad wheel support assembly that includes a roller assembly to receive and grasp the railroad wheel and rotate the railroad wheel about its center axis. A grinding assembly is also provided that includes a motor operatively connected to a grinding wheel. The motor and grinding wheel are mounted to a support assembly. The railroad wheel support assembly oscillates about an axle assembly during grinding. The grinding assembly is designed to advance the grinding wheel laterally into the railroad wheel during grinding. The lateral advancing of the grinding wheel and oscillating of the railroad wheel are controlled to achieve a finish grinding of the selected surface of the railroad wheel to a preselected contour.Type: GrantFiled: December 31, 1992Date of Patent: June 14, 1994Assignee: AMSTED Industries IncorporatedInventors: C. Dale Christie, Charles W. Taff, Jaime F. Pozo
