Patent number: 10669391Abstract: The compressible sealing element (1) comprises at least one piece made of a resilient foam (17). This foam has an open-cell content of at least 50% and has such a hardness that it requires a force of less than 2000 N to compress the sealing element (1) per meter length thereof to such an extent that the volume of a rectangular cuboid circumscribing the sealing element is reduced by 40%. The sealing element comprises a water-impermeable cover layer (18) which extends at least over its top surface. The sealing element is intended for filling at least partially the gaps between the stock rails (13) and the switch rails (12) in a railway switch to prevent the switch from being blocked in particular by snow. Advantages of the new sealing element is that it can easier be inserted in these gaps and that it has a smaller effect on the force required to close the switch so that it can also be applied closer to the free extremity of the switch rail (12).Type: GrantFiled: October 30, 2015Date of Patent: June 2, 2020Assignee: RECTICELInventors: Dieter Van Damme, Philippe Vander Schelden, Peter De Wilde, Mario Genetello, Rudi Mortelmans

Patent number: 7766283Abstract: The invention relates to a device (1) which is used to lift and displace the tongue blade (2) of a rail (6), comprising at least two rollers (12, 14) whereby the axes thereof are arranged in an essentially parallel manner in relation to a running rail (4), in order to displace the tongue blade (2) in a transversal manner in relation to the running rail (4), at least two support carrier pins (22, 24) which respectively support a roller (12, 14), and a base body (8) which supports the carrier pins (22, 24). The rollers (12, 14) have a projection which projects in at least one first direction in relation to the base body (8). The inventive device is characterised in that a covering (10) is arranged between at least two adjacent rollers and is oriented towards the first direction and at least partially covers a passage between the at least two adjacent rollers (12, 14).Type: GrantFiled: January 28, 2005Date of Patent: August 3, 2010Assignee: CDP Bharat Forge GmbHInventors: Bernd Lesemann, Frank Bornscheuer

Patent number: 7387280Abstract: In a switch including a main track and a branch track, wherein one rail of each track is each configured as a tongue rail and movable into abutment on the respective stock rail, at least one stock rail (1), in its region of abutment on the tongue rail (2), is designed to have a reduced rail head width as compared to the region located outside said region of abutment, wherein the rail head width, starting from the tip (3) of the tongue, decreases as far as to a point (4) at which the carrying wheel comes into lateral contact with the tongue rail (2) and increases in the region following thereupon, and that the tongue rail (2) is designed to be reinforced in cross section towards the stock rail (1) according to the reduction in the width of the stock rail head.Type: GrantFiled: June 16, 2003Date of Patent: June 17, 2008Assignees: VAE Eisenbahnsysteme GmbH, VAE GmbHInventors: Dieter Fritz, Hermann Orasche

Patent number: 7185860Abstract: A modular tongue switch assembly comprises a tongue pivotally connected to a slide surface, held down by a pivot retainer. The slide surface consists of slide plate sections removably attached to corresponding bed plate sections, which are in turn welded onto a base plate. Floating brace blocks hold a non-integral stock rail in place on the base plate. When the tongue moves, a horizontal lever arm actuates an inner box assembly housed within an outer box and containing the conductor rail, allowing the passing train to maintain contact with the conductor rail, if necessary. A novel rodding and lever arrangement is used.Type: GrantFiled: December 2, 2004Date of Patent: March 6, 2007Assignee: VAE Nortrak North America, Inc.Inventors: Cory O'Brien, Gary Click

Patent number: 5618013Abstract: A movable point for a crossing frog for railway apparatus of great length, incorporated in long welded rails. The point (7) is comprised of a single steel element, which comprises integral seating cross members (8). The rigidity of the point varies along all its length from a minimum adjacent a thin forward portion (9) to a maximum adjacent a wide rear portion (10). The point is constituted by a piece of austenitic manganese steel. The point can be of cast steel or can be formed by laminating and/or forging, followed by machining.Type: GrantFiled: March 13, 1996Date of Patent: April 8, 1997Assignee: Cogifer- Compagnie Generale d'Installations Ferroviaires (Societe Anonyme a Directoire)Inventor: Philippe Mugg

Patent number: 5577691Abstract: In a switch blade (point-rail) device in a grooved-rail turnout on a tram- or streetcar-type line, switch blades (2) are detachably mounted, using a clamping wedge (5) which is fastened to a support part (6) by means of a screw (12) in an essentially perpendicular direction to the running surface. Once the clamping wedge (5) has been removed, the switch blade (2) can be demounted and lifted out. Mounting is performed by pressing an inclined lateral surface (7) of the switch blade (2) against a correspondingly inclined lateral surface (8) of the support part (6). The angles of inclination of the wedge, and of the contact surface of the support part, are matched to each other so that self-locking is achieved.Type: GrantFiled: January 19, 1995Date of Patent: November 26, 1996Assignee: VAE AktiengesellschaftInventors: Egger Erich, Ossberger Heinz

Patent number: 5366184Abstract: The present invention relates to a seat for the movable point in a cradle of a crossing frog incorporated in long welded rails and the process for production of such a seat. The seat is characterized in that the connection between the movable point (1) and the element (2") of the cradle constituted by two rails (3 and 4) is effected by an essentially mechanical assembly. The invention is more particularly applicable to the field of the construction of railway equipment, particularly, crossing frogs.Type: GrantFiled: September 2, 1993Date of Patent: November 22, 1994Assignee: Cogifer-Compagnie Generale d'Installations FerroviairesInventors: Gerard Testart, Frederic Hege

Patent number: 5207401Abstract: A switch includes a frame constituted, inter alia, by a single point end plate, preferably mechanically welded, for supporting stock rails at ends thereof adjacent a principle route, and by a double heel end plate, preferably mechanically welded, for supporting heel ends of each of two stock rail/switchblade pairs adjacent a direct route and a deviated route. Spacers maintain distance between the stock rails adjacent the principal route and the stock rail/switchblade heel pairs adjacent the direct and deviated route. Sole plates support the stock rails and/or switchblades. Inner stops are placed between the switchblades in the vicinity of their heel ends and are carried by the sole plates. Outer stops are placed between the stock rails and the switchblades in the vicinity of their point ends and are carried by the stock rails.Type: GrantFiled: May 23, 1991Date of Patent: May 4, 1993Assignee: Cogifer-Compagnie Generale d'Installations FerroviairesInventor: Gerard F.
