Patent number: 11821148Abstract: In a stock rail for use in a railroad switch, there are a rail head, a rail web and a rail foot, wherein the stock rail has a first longitudinal section forming an abutment region for a tongue rail and a second longitudinal section lying outside the abutment region, wherein the stock rail in the second longitudinal section has a cross-sectional base profile with a central axis extending through the center of the rail head cross section, wherein the rail head in the first longitudinal section is machined starting from the cross-sectional base profile so that the running edge, compared to the base profile, lies closer to the central axis of the stock rail, the rail head having substantially no width reduction at least at a first point within the first longitudinal section and having a maximum width reduction at least at a second point within the first longitudinal section, it is provided that the running edge at the first point and the running edge at the second point lie substantially in a common running edgeType: GrantFiled: June 11, 2019Date of Patent: November 21, 2023Assignees: VOESTALPINE TURNOUT TECHNOLOGY ZELTWEG GMBH, VOESTALPINE RAILWAY SYSTEMS GMBHInventor: Erich Wipfler

Patent number: 9453307Abstract: In a railway switch with a main track and a branch track, in which one rail of each track is each configured as a tongue rail and movable into abutment on the respective stock rail, the stock rail comprises in the region of the abutment on the tongue rail a deviating course of the running edge and the running edge of the tongue rail comprises a curve progression, whose imaginary extension comprises an overcutting or an undercutting with the running edge of the stock rail.Type: GrantFiled: February 12, 2013Date of Patent: September 27, 2016Assignees: VOESTALPINE WEICHENSYSTEME GMBH, VOESTALPINE VAE GMBHInventors: Johann Gsodam, Heinz Ossberger

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: 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: 5451018Abstract: A railway tongue and junction rail assembly including a mounting fixed to the junction rail. The tongue abuts the junction rail at an inclined junction and is releasably secured within the mounting with the mounting being the sole means of joining the tongue to the junction rail.Type: GrantFiled: December 23, 1993Date of Patent: September 19, 1995Assignee: BWG, Butzbacher Weichenbau GmbHInventors: Fridbert Heinze, Erich Nuding, Friedhelm Wojtek

Patent number: 4925135Abstract: An arrangement is proposed for controlled guidance of a wheel axle (22) or of a bogie of a rail vehicle passing over points, whereby the wheel contact point (48, 50) is subjected to a controlled influence such that the wheel axle runs substantially vertical to the track longitudinal axis. The controlled influence of the wheel contact point can be exerted by, for example, the stock rail (32) veering away outwards in the area that the blade begins.Type: GrantFiled: January 26, 1988Date of Patent: May 15, 1990Assignee: BWG Butzbacher Weichenbau GmbHInventors: Rudiger Ziethen, Sebastian Benenowski, Alfred Kais, Erich Nuding

Patent number: 4224875Abstract: A static switching apparatus for a track vehicle includes a main line track and a switch track which at a switching junction both include a conventional track rail and a specially constructed rail. A switching cam including cam faces is positioned at the junction and includes straight and curved cam surfaces which are selectively engaged by cam followers supported on the vehicle to provide for steering of the vehicle. The cam followers are lowered and raised vertically by fluid extensible devices which also move them in an orbital path into cam surface engagement.Type: GrantFiled: June 15, 1978Date of Patent: September 30, 1980Assignee: Pullman IncorporatedInventors: Willis H. Knippel, Thomas R. Schmitz
