Patent number: 7874527Abstract: A rail fastening apparatus fastens an inner stock rail in a railway slide chair assembly. The apparatus includes a base plate. The base plate has on one face a rail seat region on which the inner stock rail sits when the slide chair assembly is in use. A resilient rail fastening clip restrains the inner stock rail. A locating means locates the rail fastening clip in a first position. A loading means vertically deflects the clip so as to produce a load in a toe portion of the clip.Type: GrantFiled: June 10, 2005Date of Patent: January 25, 2011Assignees: Pandrol Limited, VAE Eisenbahnsysteme GmbH, VAE GmbH, BWG GmbH & Co.

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: 7137601Abstract: A check rail arrangement for a switch or an intersection, the arrangement including a grooved rail (16) provided with a grooved rail head (14), a groove (18) and a lip (52), and a check rail (12) which is supported at least on the lip and is arranged by a fixing mechanism in such a way that it can be displaced in relation to the grooved rail. The aim of the invention is to be able to easily displace the check rail. To this end, a fish-plate block (40) extends from the grooved rail (16), the fish-plate block including a longitudinal groove (42) which extends perpendicularly to the longitudinal direction of the grooved rail and in which a slot pin (44) engages in an adjustable manner. The slot pin can be tightened by a screw (46) extending from the check rail (12).Type: GrantFiled: June 25, 2003Date of Patent: November 21, 2006Assignees: BWG GmbH & Co.

Patent number: 6860433Abstract: A bearing for a section of a track includes, along the track sections, profile sections which deviate from each other, especially in the form of points. A plurality of supporting points is provided with a ribbed plate, in addition to an intermediate layer made of an elasticized material disposed between the ribbed plate and an associated railway sleeper. In order to obtain identical subsidences along the sections of track, substantially each support point has an identical maximum subsidence with respect to each excavated track section.Type: GrantFiled: September 25, 2001Date of Patent: March 1, 2005Assignees: BWG GmbH & Co.

Patent number: 6543728Abstract: The invention relates to a cross frog (10) for points and crossings, comprising a cross frog tip (14) and wing rails (16, 18) and running rails (20, 22) situated either side of this point, each with a basic course (38) aligned with a main or secondary track (26, 28). The aim of the invention is to reduce the wear around the cross frog tip without reconstructing the cross frog tip itself or the guard rails allocated thereto or realigning them in relation to each other. To this end, at least one of the running rails deviates from its basic course in the area of the cross frog tip, in such a way that the movement of a rail vehicle running through the main or secondary track is influenced through its wheel frame or bogie axle, away from the cross frog tip.Type: GrantFiled: January 7, 2002Date of Patent: April 8, 2003Assignee: BWG GmbH & Co. KGInventors: Sebastian Benenowski, Alfred Kais, Stefan Schmedders
