The scan results are combined with the stored data to produce a corrected optimal drill pattern, which is used to drill the tie. The drilled tie moves to a plate and screw loading station, where the proper plates and fasteners are attached. A fourth station inspects the assembled tie. If it is properly assembled, the screw spikes are tightened and the plated tie moves to an outfeed deck, where it is marked for identification and removed for storage and shipping.Type: GrantFiled: September 28, 2006Date of Patent: July 22, 2014Assignee: voestalpine Nortrack Inc.Inventor: Allen J.

Patent number: 6595140Abstract: A railway tie plate insertion vehicle includes operator's chairs mounted on both sides of the vehicle; with the occupants of each chair being provided with a tie plate insertion wand including controls for movement of the vehicle. A tie magazine deposits a tie plate on the tie upon actuation by the operator when a tie plate has not been previously deposited. A first rail clamp includes a pair of rollers for engaging the rail, attached to the ends of a pair of scissor arms, so that raising the rail draws the scissor arms closer together, increasing the gripping pressure on the rail. A similar rail clamp is located at the rear of the vehicle, which also includes an electrical connection for the operator's wand, thereby permitting tie plate insertion from the rear of the vehicle when obstacles are present along the sides of the vehicle.Type: GrantFiled: June 5, 2002Date of Patent: July 22, 2003Assignee: Harsco Technologies CorporationInventors: Harry Madison, Christian Glen Brand

Patent number: 6546612Abstract: Apparatus and methods are disclosed by which wooden railroad ties are pre-plated prior to use in constructing and/or repairing railroad lines. Methodology disclosed comprises placing two plates on top of each of a succession of wooden ties, temporarily positioning disclosed one of the two plates on each tie with a distance or spacer template temporarily clamping the two plates accurately to the tie using a jig, starting a field spike and a gauge spike (usually with one or more sledge hammers) into each wooden tie through the selected apertures in each plate, and further driving the started spikes into the associated tie (usually using a jackhammer). Typically, the field spike is located outside the field flange of the plate and is driven until the head of the spike is contiguous with the plate. Typically, the gauge spike is displaced through an aperture in the gauge flange of the plate until the head is about 1½ inches above the plate.Type: GrantFiled: June 25, 2001Date of Patent: April 15, 2003Inventors: Robert Ollendick, David Ollendick
