Patent number: 6178895Abstract: A floor plate assembly for a railway freight car structure. The assembly includes a floor plate and set of floor plate support assemblies, each having a base and at least one side wall. The side wall has an outer margin that in some embodiments is welded to the floor plate. A reinforcing bar is welded to the base and has a margin which is located closely adjacent to the floor plate and which is welded to the floor plate in some embodiments. In some embodiments the floor plate support assemblies each have two side walls and the reinforcing bar is welded to the base between the side walls. The floor plate support assemblies may be formed away from the railway freight car that is under construction by using a jig to facilitate welding the reinforcing bar to the base. The floor plate assembly may also be assembled separately and then may be efficiently welded to the members of the freight car underframe.Type: GrantFiled: April 19, 1999Date of Patent: January 30, 2001Assignee: Gunderson, Inc.Inventors: Gregory J. Saxton, Bruce D. Becker

Patent number: 6059075Abstract: A fully protective multi-unit railroad freight car for carrying motor vehicles on two or three levels with the lowest level being in a cargo well between a pair of deep side sills. A pair of vehicle-carrying decks are adjustable in height and are counterbalanced against each other during adjustment of their locations. A roof structure is light in weight and constructed of corrugated sheet metal with a self-supporting central portion. The ends of the car are equipped with three-panel folding doors, and a flexible diaphragm closes the space between articulated adjacent car units supported by a shared truck. A modular brake operating system is mounted on the car body. An easily removable brake system module incorporates a compressed air reservoir, a dummy reservoir, a brake control valve, train line and brake cylinder connector lines, and a support structure. The module is easily removable and replaceable, allowing for repair and system testing at a shop.Type: GrantFiled: March 13, 1998Date of Patent: May 9, 2000Assignee: Gunderson, Inc.Inventors: Gregory J.

Patent number: 5758584Abstract: A railroad freight car of the center beam type, in which the upright center beam has a top chord interconnected with a bulkhead at each end of the body of the car, and spaced-apart upright columns and diagonal structural members interconnect the top chord with the center sill of the car body. At each end of the center beam an upper end of a diagonal bulkhead brace included in the center beam is attached to the bulkhead at an intermediate height, and a lower end is attached to the center sill adjacent one of the columns. In one version of the car a second diagonal bulkhead brace extends upward to the top chord from a location at an intermediate height on the bulkhead. The car may include inwardly sloping decks oriented normal to load bearing faces of the center beam, with the decks incorporating a unified structure of which a floor sheet is a load-carrying part and is supported by longitudinal stringer channels.Type: GrantFiled: February 19, 1997Date of Patent: June 2, 1998Assignee: Gunderson, Inc.Inventor: Gregory J.

At each end of the center beam an upper end of a diagonal bulkhead brace included in the center beam is attached to the bulkhead at an intermediate height, and a lower end is attached to the center sill adjacent one of the columns. There is no solid plate extending from the top chord to the center sill and from the bulkhead toward the other end of the car. In one version of the car a second diagonal bulkhead brace extends upward from a location at an intermediate height on the bulkhead to the top chord.Type: GrantFiled: May 31, 1996Date of Patent: May 6, 1997Assignee: Gunderson, Inc.Inventor: Gregory J.

Patent number: 5611285Abstract: A railroad freight car including a cargo well for carrying optionally either intermodal cargo containers or highway semitrailers has a side sill structure including a deep rectangular top chord and a depending web, supporting a well floor structure. The well floor structure includes reinforcing longitudinal and transverse channel members and horizontal top and bottom plates attached to the channels. Large circular openings, aligned with one another, are defined in both the top and bottom plates, and a peripheral ring of vertical material interconnects the margins of the top and bottom plates around the openings. A reinforcing walkway structure is located atop each side sill at each end of the cargo well. In a multi-unit car adjacent car units are supported on a single shared wheeled truck.Type: GrantFiled: February 14, 1996Date of Patent: March 18, 1997Assignee: Gunderson, Inc.Inventor: Gregory J.

Large circular openings, aligned with one another, are defined in both the top and bottom plates, and a peripheral ring of vertical material interconnects the margins of the top and bottom plates around the openings, providing a light but stiff floor structure with a small vertical height. A side sill reinforcing walkway structure is located atop each side sill at each end of the cargo well, but is low enough to avoid interference with handling trailers.Type: GrantFiled: November 23, 1993Date of Patent: June 13, 1995Assignee: Gunderson, Inc.Inventors: Gregory J. Saxton, James A. Hilsenteger

Patent number: 5379702Abstract: A railroad freight car including a cargo well for carrying optionally either intermodal cargo containers or highway semitrailers has a side sill structure including a deep rectangular top chord and a depending web, supporting a well floor structure. Each side sill has a height above the well floor, and a spacer is connected to the car body by an attachment which permits the spacer to be pivoted between a raised position clear of the well floor and a lowered position upwardly adjacent the well floor. The spacer has a predetermined height sufficient to support a trailer located in the cargo well, with its wheels resting on top of the spacer, high enough to locate lifting points on the trailer above the height of the side sill.Type: GrantFiled: November 18, 1993Date of Patent: January 10, 1995Assignee: Gunderson, Inc.Inventors: Gregory J. Saxton, Gareth R. Thomas, Charles C. Hill, Kenneth L. Weselake

Patent number: 5170718Abstract: A multi-unit articulated railway freight car defining a container well in each of the several units, with container support members attached to the side sills of each unit to support standard intermodal cargo containers at a location low enough to permit a second tier of containers to be stacked atop a bottom tier without exceeding the maximum height restrictions of most main railroad lines, although ample clearance is preserved beneath the bottom of the car when fully loaded. Each container support member is constructed of thick plate steel of high strength, formed cold to include residual internal stresses in order to resist failure when subjected to the loads imposed by supporting loaded containers carried in the container well. The side sill structures are of box tube and formed sheet construction of small enough width to permit carriage of newer, larger, sizes of intermodal cargo containers without the car or containers protruding outside the clearance available along most railroad lines.Type: GrantFiled: April 17, 1991Date of Patent: December 15, 1992Assignee: Gunderson, Inc.Inventors: Charles C. Hill, Gareth R. Thomas, Gary S. Kaleta, Gregory J. Saxton

Patent number: 4930426Abstract: An adjustably positioned container guide and spacer device to be mounted on a side wall defining a container well of a railroad car for receiving intermodal cargo containers of different widths, the device acting as a guide during loading of a container into the container well, and acting to restrain a container, particularly one narrower than the width of the container well, to prevent such a container from moving laterally too far once it has been placed within the container well. A sloping guide surface and a blunt, convexly curved spacer nose surface of the guide body are presented so as to guide a container to the proper location within a container well, and the nose surface thereafter prevents the container from moving an excessive distance laterally within the container well when the guide body is latched in the correct one of the available inner and outer positions, as determined by the width of the container.Type: GrantFiled: November 30, 1988Date of Patent: June 5, 1990Assignee: Gunderson, Inc.Inventors: Gregory J.
