Patent number: 8033480Abstract: Fastening for a rail and arrangement for fastening of rails The invention relates to a fastening for a rail for securing a rail (10) whose foot is resting on a concrete sleeper (16), comprising at least one elastic clip (20) having several legs of which at least one leg extends inside a shoulder (42, 44) or channel of a holder (24) that is connected to the concrete sleeper, and at least one further leg rests on the rail foot. For securing a rail to the necessary extent with simple design means and in space-saving form, it is suggested that the holder (24, 26) is arranged detachably in the concrete sleeper (16) or in a plate element resting thereon and is connected to the concrete sleeper by a bolt element.Type: GrantFiled: April 28, 2005Date of Patent: October 11, 2011Assignees: BWG GmbH & Co. KG, VAE GmbH, Pandrol Limited, VAE Eisenbahnsysteme GmbHInventors: Hubertus Höhne, Hans-Ulrich Dietze, Heinz Ossberger, Josef Leitner, John Porrill, David R. Seeley

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: 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. KG, VAE GmbHInventors: Hans-Ulrich Dietze, Stefan Schmedders

Patent number: 6601518Abstract: The invention relates to a system for securing and/or controlling the final position of a tongue rail (14) that can be adjusted in relation to a rigid rail (12). A catch element extends from said tongue rail and interacts with a lever element in such a manner that in the respective final position of the tongue rail the latter is supported and the position of the tongue rail is measured.Type: GrantFiled: March 15, 2002Date of Patent: August 5, 2003Assignee: Werth Messtechnik GmbHInventors: Albrecht Demmig, Hans-Ulrich Dietze, Hubertus Höhne

Patent number: 6527231Abstract: The invention relates to a superstructure points device, in particular intended for a grooved rail, comprising a box-like substructure (32) with stock rail (14), if necessary an additional/supporting rail (16) and slide plate (18) on which a tongue rail (20) is slidably mounted. In order to mount the rails of the points device elastically, while also allowing the option of simple removal from the rail/road bed, it is proposed that the box-like substructure (32) is mounted elastically in a stationarily arranged frame (38) of the points device.Type: GrantFiled: March 23, 2001Date of Patent: March 4, 2003Assignee: BWG Butzbacher Weichenbau GmbH & Co.

Patent number: 6409092Abstract: A superstructure arrangement for a track comprising a rail fastened to a securing device such as a ribbed plate which is disposed above a concrete sleeper, with an intermediate layer extending between the sleeper and the securing device. The rigidity of the intermediate layer is variable and rated so that at the maximum permissible stress in the rail, caused by bending under wheel lead, the elastic property changes to substantially non-elastic.Type: GrantFiled: January 10, 2000Date of Patent: June 25, 2002Assignee: BWG Butzbacher Weichenbau GmbH & Co.

Patent number: 6062144Abstract: A method and device for the elastic bending of a support (16) with at least one bendable end (24), intended in particular for a flexible switch (10). To achieve an elastic line of a finite radius of curvature also at the free end of the support, a bending moment diverging from zero is generated in the elastically bendable end (24) of the support (14) by applying a force coupling to an auxiliary lever (28).Type: GrantFiled: May 16, 1995Date of Patent: May 16, 2000Assignee: BWG Butzbacher Weichenbau GmbHInventors: Sebastian Benenowski, Hans-Ulrich Dietze, Erich Nuding, Stefan Schmedders, Rudiger Ziethen

Patent number: 5645216Abstract: A bearing system for a part of a railroad track, such as a rail-fastening or ribbed slab (10), supported by elastic elements on, for example, a railroad sleeper. The elastic elements form a spring system with a kinked characteristic curve such that when the spring system is subjected to force that is smaller than the forces active in the operative range (16) of the spring system, the characteristic curve rises steeply and, in the operative range (16), runs flat.Type: GrantFiled: March 31, 1995Date of Patent: July 8, 1997Assignee: BWG Butzbacher Weichenbau GmbHInventors: Sebastian Benenowski, Albrecht Demmig, Hans-Ulrich Dietze, Alfred Kais, Erich Nuding

Patent number: 5390881Abstract: A roller assembly for a rail switch tongue used with a stock rail exhibiting reduced friction and resistance to vibration includes roller elements for supporting the switch tongue. Each roller element is supported by elastomer springs, one having a damping and the other having a supporting characteristic. The spring elements are mechanically coupled so that loading of the roller elements by the switch tongue causes a change in the spring length.Type: GrantFiled: July 12, 1993Date of Patent: February 21, 1995Assignee: BWG Butzbacher Weichenbau GmbHInventors: Sebastian Benenowski, Erich Nuding, Hans-Ulrich Dietze
