Patent number: 5650576Abstract: The device that is used to measure the switching force in railway points incorporates a measuring bolt (5) that can be inserted into a joint in the point drive. At the unattached end of the measuring bolt there is a head (7) in which an electro-mechanical sensor (8) is arranged. The precise adjustment of the measuring bolt (5) within the joint is effected by using a spacer (10), which simplifies the removal of the measuring bolt once the measurements have been made.Type: GrantFiled: February 27, 1995Date of Patent: July 22, 1997Assignee: VAE AktiengesellschaftInventor: Gerald Durchschlag

Patent number: 5566912Abstract: In a device for locking end positions of movable switch parts, in particular, a switch lock, two relatively movable parts are displaceable into a position non-positive in respect of at least one direction of movement. The relatively movable parts are formed by a tube and a pin axially guided within the tube. In addition, separate locking elements formed by heads of flexible tongues are provided.Type: GrantFiled: May 16, 1995Date of Patent: October 22, 1996Assignee: VAE AktiengesellschaftInventor: Gerald Durchschlag

Patent number: 5499786Abstract: In a device for facilitating the re-positioning of moveable rails or rail components, in particular of tongue rails (7), in which the rails (7, 7'), during the re-positioning operation are supported on rollers (10, 10') forced against the underside of the rail base by spring action, the rollers (10, 10') in at least one end position (7, 7') of the re-positioning operation are pressed by the force of the spring against one edge (14, 15) of the rail base. In this way it is possible to combine the advantages of reduction of the sliding friction during the re-positioning operation with a flexible securing of the end position of the currently involved adjusted position of the moveable rail or rail component (7, 7').Type: GrantFiled: October 14, 1993Date of Patent: March 19, 1996Assignee: Voest-Alpine Eisenbahnsysteme AktiengesellschaftInventors: Gerald Durchschlag, Herbert Klein

Patent number: 5374016Abstract: This invention relates to a device for determining lateral and/or vertical deviations in the path taken by a wheel at railway points or crossings. One of the aims of this invention is to provide data on the condition of such points or crossings, particularly as to the degree of their wear. Further, it is another aim of the invention to create a device which is easier to relate the signals from the sensors to the direction of the loads giving rise to these signals, and which at the same time is simpler and more economical to assembly while at the same time ensuring reproduceable results.Type: GrantFiled: June 17, 1993Date of Patent: December 20, 1994Assignee: Voest-Alpine Eisenbahnsystems AktiengesellschaftInventor: Gerald Durchschlag

Patent number: 5356224Abstract: In the case of a device for fastening of at least one exchangeable elongate slide insert (5), in particular synthetic plastics material slide inserts, in recesses of a slide base or ribbed plate (4), in which the side surfaces of the slide insert (5) are at least partly gripped by inwardly-sloping or undercut walls of the recesses, the slide inserts (5), on their underside and transversely to their longitudinal axis, have a straight-line groove, in which case the slide base or ribbed plate (4) on its upper side has a groove open towards the top in alignment with the groove in the insert, and the groove in the slide base or ribbed plate (4) and the groove in the slide insert (5), in the locking-in position, define a clear opening for the insertion of a rod-shaped locking-in member (7), the free ends of which project, in a plastically deformable mariner, beyond the edges of the slide base or ribbed plate.Type: GrantFiled: May 12, 1993Date of Patent: October 18, 1994Assignee: Voest-Alpine Eisenbahnsysteme AktiesengesselschaftInventor: Gerald Durchschlag

Patent number: 5253830Abstract: In a method for monitoring the condition of rail switch points and for detection of premature abrasive wear-and-tear in the region of the tongue switching rail (3) of the points, the signals from at least one proximity sensor (2) in the region of the tongue switching rail (3) of the points are evaluated when the tongue switching rail is travelled upon, and the smallest measured value of the separation distance (l) during the travel is stored in memory. The smallest measured value stored in memory and at least a first limiting value for the smallest separation distance are compared with one another and, when the smallest measured value in memory exceeds this first limiting value, a warning signal is generated.Type: GrantFiled: May 8, 1992Date of Patent: October 19, 1993Assignee: Voest-Alpine Eisenbahnsysteme Gesellschaft m.b.H.Inventors: Wolfgang Nayer, Gerald Durchschlag

Patent number: 4982919Abstract: In a reversing device for the movable parts of a railway switch, in which movable wing rails are, in their end positions, alternately engaging the frog and are supported in their engaging positions by supporting rods extending in the longitudinal direction of the wing rails and which are slideably guided on the sleepers or, respectively, base plates, the supporting rods include at least one thrust support cooperating, for the purpose of shifting the wing rails relative to the frog, with thrust supports of the wing rails. In this case, at least one of the mutually cooperating surfaces of the thrust supports of a wing rail and/or supporting rod is formed of a wedge surface passing over into a supporting surface extending in essentially parallel relation to the longitudinal direction of the supporting rod. The supporting surface cooperates, in the position in which the wing rail contacts the frog, with the thrust support of the wing rail.Type: GrantFiled: November 7, 1988Date of Patent: January 8, 1991Assignee: Voest-Alpine Maschinenbau Gesellschaft mbHInventors: Gerald Durchschlag, Alfred Lang

Patent number: 4927102Abstract: In a reversing device for movable parts of a railway switch within the deflection area of a railway switch, in particular tongue rails, monorail deflection device or movable stock rails, in which device the movable rails can be caused to contact rigid switch parts, the movable rails are supported in their contacting position by supporting rods extending in the longitudinal direction of the rail the supporting rods are slideably guided on the sleepers or, respectively, base plates in the longitudinal direction of the rails. In this case, the supporting rods are designed as adjusting members for the reversing operation and comprise thrust supports cooperating with thrust supports of the movable rails for shifting the rails. At least one of the mutually cooperating surfaces of the thrust supports of rail and/or of supporting rod is formed of a wedge surface passing over into a supporting surface extending in an essentially parallel relation to the longitudinal direction of the supporting rod.Type: GrantFiled: November 7, 1988Date of Patent: May 22, 1990Assignee: Voest-Alpine Maschinenbau Gesellschaft m.b.H.Inventors: Gerald Durchschlag, Alfred Lang, Franz Rotter, Dieter Fritz, Heinz Kopilovitsch

Patent number: 4860978Abstract: A rail switch control mechanism including a locking clamp which is shiftable using a path rod. The locking clamp has, on an end facing the switch tonque, a swivel head. The swivel head is swivelably connected with a switch tongue. In use, the locking clamp cooperates with a locking piece. In the locked position of the clamp, a shoulder of the locking clamp contacts a shoulder of the locking piece. The switch tongue rail is linked to the swivel head with the interposition of a pin arranged with an elongated slot extending longitudinally of the tongue rail. The elongated slot is arranged within a connecting member which is rigidly connected to the switch tongue rail, e.g. by being threadedly connected, to the web of the switch tongue rail.Type: GrantFiled: June 9, 1988Date of Patent: August 29, 1989Assignee: Voest-Alpine AktiengesellschaftInventors: Gerald Durchschlag, Alfred Lang
