Patent number: 9328464Abstract: A railroad rail includes a body defining a first section and a tapered second section with the body defining a head section, a web section depending from the head section, and a base section depending from the web section. The head section, the web section, and the base section define an end surface configured to mate with a corresponding end surface of a complementary railroad rail when joined together. The railroad rail is formed from a single bent railroad rail having only a single bend defined by the head section, web section, and base section of the body of the railroad rail.Type: GrantFiled: September 12, 2013Date of Patent: May 3, 2016Assignee: Koppers Delaware, Inc.Inventors: William Thomas Urmson, Jr., John W. Mospan

Publication number: 20120031988Abstract: A leveling joint between connected ends of two rails of different profiles is provided with a connector/juncture bar members which is configured to fit with and engage corresponding surfaces formed on the rails when the rails are connected together. The leveling joint so formed is one with increased strength, with ease and accuracy of alignment during assembly. The leveling joint is formed of several structural members, yet functions as and affords the strength and stability of a solid, unitary assembly.Type: ApplicationFiled: August 6, 2010Publication date: February 9, 2012Inventor: Arturo A.

Publication number: 20080000999Abstract: A rail brace assembly is adapted to buttress the head of a stock rail selected from one of two different stock rail groups mounted on the top surface of a brace plate. The assembly includes a stop block assembly also is affixed to the brace plate top surface. A rail brace moveable between a first brace position in which it buttresses the head of a rail from a first stock rail group and a second brace position in which it buttresses the head of a rail from a second stock rail group, has a pair of spaced side walls, a upwardly facing top surface, first rail group head and base fishing surface contact areas, second rail group head and base fishing surface contact areas, a first rail group brace plate contact surface and a second rail group brace plate contact surface. An elastic fastener cooperates with a clip housing to clamp the rail brace against the stock rail.Type: ApplicationFiled: June 29, 2006Publication date: January 3, 2008Inventors: James A. Remington, Karl E. Axthelm, Phillip R. Merrifield

Patent number: 7210636Abstract: In a transition rail (1) for the connection of rails having different rail cross sections (2, 3), the transition rail (1) comprises two transition zones (a,c), wherein in a first transition zone (c) the larger-height cross-sectional profile is reshaped to transition into a smaller profile height and in the following, second transition zone (a) the rail foot is worked to match the new profile of the consecutive rail foot. The method for producing the transition rail is characterized in that the transition rail is at first heated and introduced into a press mold, whereupon the rail is reshaped in the web region and pressed in the direction of the profile height, and that the rail foot is mechanically worked following complete reshaping.Type: GrantFiled: April 4, 2003Date of Patent: May 1, 2007Assignees: VAE Eisenbahnsysteme GmbH, VAE GmbHInventors: Helmut Jäger, Wolfgang Hölzl

Patent number: 6398122Abstract: A railroad track has a heavier rail section and a lighter rail section. Compromise rails join the heavier and lighter rails. Each compromise rail has a head with a heavier end to match the profile of the heavier rails and a lighter end to match the profile of the lighter rails. Each compromise rail is symmetrical about a straight center line extending from one end to the other. The width of the compromise rail tapers uniformly from the lighter end to the heavier end. This results in a slightly different gauge along the compromise rail section from the standard gauge. The different gauges are accommodated by adjusting the gauge at an end portion of the lighter rail section and at an end portion of the heavier rail section.Type: GrantFiled: February 16, 2001Date of Patent: June 4, 2002Assignee: Progress Rail Transcanada CorporationInventors: Peter M. Kowalyk, Douglas J. Finigan

Patent number: 6325299Abstract: A compromise rail is formed of a single length of stock rail. One end of the rail is forged over a distance of 19-48 inches to reduce the height of the forged portion, which is then machined to match the running rail to which that end is to be attached. The invention avoids the expense and inconvenience of flash butt welding a forged section to a uniform profile rail as is done in prior art compromise rails.Type: GrantFiled: May 11, 2000Date of Patent: December 4, 2001Assignee: Vae Nortrak North America Inc.Inventors: Tom Stanley, Paul Valastin

Patent number: 4922743Abstract: The disclosed connection bar is elongated, adatped to overlap respective adjacent ends of two rails, and the top and bottom portions at each end of the bar have elongated contact faces shaped to cooperate flush against respective surfaces on these rails. A pair of holes is provided in a web portion of the bar, and securing devices may be extended through the holes for clamping the bar against the rails. An elongated reinforcing rib may be formed on the web portion, extended across the bar transverse to and between the enlarged top and bottom portions, and located to line up adjacent the ends of the rails when the bar is secured to the rails. Other reinforcing ribs may also be extended across the web portion, transverse to and between the top and bottom portions; and these other ribs are located outwardly beyond the holes.Type: GrantFiled: May 9, 1989Date of Patent: May 8, 1990Assignee: Track-Work Products, Inc.Inventors: Norman W. Hillegass, Walter J. Drone

Patent number: 4105160Abstract: A joint bar for joining a first rail having a head and a depending terminal web, and a second rail having a head, a depending web and a transverse flange; the joint bar has a first U-shaped portion with a lower bight and upstanding legs, and a second portion comprising a pair of spaced longitudinally extending elements, each extending from a leg of the first portion. Each element has an upper bulbous head, a lower flange, and a connecting web.Type: GrantFiled: May 10, 1977Date of Patent: August 8, 1978Inventor: James L. Ramer
