Patent number: 7309050Abstract: A grooved rail core piece including a core piece intersection area formed by intersecting grooves as an overflow area. The core piece has two construction profiles with interconnected outer fishing surfaces (22,24) extending in a longitudinal direction. In order to enable the intersection area of the core piece to be renewed in a simple manner, the intersection-point area of the core piece includes an interchangeable insert (36) which is arranged in a recess in an at least positive fit, the recess being defined by the sections of the construction profiles and by the sections of the lining parts (30,32) disposed in the outer fishing surfaces (22, 24), and the insert is fixed by means of at least two wedge elements (38, 40) which can be clamped in the lining parts. The lining parts and the construction profiles are connected by means of at least one clamping element protruding there through in a non-positive fit.Type: GrantFiled: March 10, 2004Date of Patent: December 18, 2007Assignees: BWG GmbH & Co., KG, VAE GmbHInventors: Fridbert Heinze, Thomas Christ, Torsten Reck

Patent number: 6276643Abstract: The strength and reliability of railroad, track structures, such as frogs, crossings, and guardrails, is enhanced. Filler members and filler blocks are fitted in to support and strengthen the structures. The filler members and filler blocks provide better matching and alignment of load transfer surfaces. The track structures with the improved components are more easy to align and assemble. The strength of the assembled track and structures is also increased, and the structures are more easily maintained.Type: GrantFiled: June 26, 2000Date of Patent: August 21, 2001Inventor: Arturo A. Ortiz Rivas

Patent number: 6266866Abstract: An improved cast insert for a railway frog has two extensions extending in substantially the same direction away from the body portion of the casting and the end of each of the extensions has a cross sectional profile corresponding to the profile of the head and web of a rail but including only one side of what would normally be the base of a rail. A frog assembly is made by providing such an insert, machining each of two rails to also remove one side of the base near the end of the rail and attaching the machined end of each of the two rails to the end of one of said extensions such that the sides of the rails from which the base has been machined away face one another.Type: GrantFiled: July 21, 1999Date of Patent: July 31, 2001Assignee: VAE Nortak North America Inc.Inventors: Jacqueline Ramirez, Al Forshaw, Gary Click

Patent number: 5704570Abstract: A nose type rail member for a crossing member applied to a turnout or wayside switch system on the ground for a train and the like, is made of high carbon steel material containing 0.70 to 0.82 wt. % of carbon. The rail member is constructed by a pair of rail parts, which have a concave at a side of the middle support part. A backing plate is made of the same material as the rail member, or a steel material having a less carbon content than that of the rail member, and is held by a pair of the opposite concaves. A pair of the head portions and the base portions at a side thereof are joined by means of electron beam welding, and the joined rail member is subjected to S.Q. heat processing; whereby at least a wheel tread of the rail member becomes a homogeneous and fine pearlite structure.Type: GrantFiled: December 16, 1993Date of Patent: January 6, 1998Assignee: Yamato Kogyo Co., Ltd.Inventors: Takaaki Irie, Hisashi Takahata

Patent number: 5456430Abstract: An improved frog is provided with an interchangeable insert for a railroad turnout, such as a frog or crossing. The frog has a new modular interchangeable insert, which permits easy changing of worn pieces in situ.The insert is a solid, unitary piece of high strength steel of two different geometrical shapes. An upper part of the insert is triangular in shape having a flat or planar base surface. A lower part of the insert is of a rectangular, planar sided member of box shape and serves as the web, running from the front to rear of and through the center and beneath the triangular upper part.Type: GrantFiled: May 3, 1994Date of Patent: October 10, 1995Inventor: Arturo A.
