Definitions

  • Patents 3,165,838 and 3,314,373, both issued to the present inventors are representative of known devices and methods of aligning railway tracks in which two chords of diiferent length are used.
  • the end points of two chordal elements are held at a given distance from one rail of the track.
  • the distances between the chords of the rail and the chordal elements are then measured, for instance at the center of the shorter chord.
  • On the basis of these arc-height spacings it can be determined in what direction and to what extent the track must be displaced transverse to its longitudinal direction in order to obtain the greatest possible vibration-free travel of trains on the track.
  • chordal elements form part of an electric circuit and are associated with fork members which are displaceable, for instance on a spindle by means of an electric motor, transverse to the direction of the track.
  • the electric motor is connected for rotation in one direction or the other when the chordal element comes into contact with one or the other of the tines of the fork.
  • the railway vehicle shown has a telescopically extractable bar 7 at both its front and at its rear ends.
  • Measurement carriages 6 and 8 are respectively fastened to front and rear bars.
  • the measurement carriages 6 and 8 are conventional and therefore have not been shown in detail. Each carriage can be pressed against one or the other of the rails so that errors in measurement as a result of tolerances are avoided.
  • FIG- URE 4 One possible switching arrangement is shown in FIG- URE 4 in which the wipers 17 and 17' of the potentiometers 14 and are connected to a measuring instrument 18.
  • the wipers 17 and 17' assume a position in which they tap off the same voltages from their associated potentiometers 14 and 15.
  • the measuring instrument 18 accordingly does not receive any voltage difference and indicates a value of 0.
  • the resistance of the potentiometers 14 and 15 should be in a ratio of 1:3 (referring to the angle of rotation and assuming the same diameter for the pulleys 12 and 12'). The same effect is of course obtained when the ratio of the diameter of the pulleys is correspondingly varied.
  • This potentiometer 14 is the actual measuredvalue transmitter.
  • a member consisting of a feeler 38 and corresponding contacts 39 and 40 serve, if necessary, to balance the voltages.
  • Resistors 23 and 23 (the latter being variable) serve for adapting and balancing of the switching and measuring currents fed to the potentiometers and the indicating member 18, respectively.
  • At least one linearly extending chordal reference element mounted on said rail vehicle with the ends of said element being fixed a given distance from one rail of the track;
  • a transmission means connected between the chordal element at a place between the ends thereof and said transducer to determine the variation of arc-height distance upon travel over the track;
  • a track aligning machine in which the adjusting device comprises a housing displace ably mounted on the undercarriage transverse to the direction of the track, said electro mechanical transducer being mounted in said housing.
  • a track aligning machine in which the switch circuit contains an indicating instrument which indicates the direction in which the track is displaced and the amount of correction required.
  • a track aligning machine in which the transmission device consists of a flexible element fastened to the chordal element.
  • two transmission means are fastened to the undercarriage of the rail vehicle and each of which engages in one of the chordal elements in order to sense their displacements transverse to the direction of the track;
  • a track aligning machine in which the switch circuit contains two variable resistors each of which has a wiper, another resistor connected between the two wipers, said two wipers being adjusted as a function of the advance of the rail vehicle on the track.
  • a track aligning machine further comprising a cam, a measurement wheel traveling on the rail and which rotates accordingly upon the advance of the vehicle, said cam being operatively connected to said wheel to rotate in such a manner that the transition path from a linearly extending section of the track into a curved section corresponds to less than one full revolution of the cam and a cam follower hav ing one end against the cam and the other end operatively connected to displace the linear resistor.
