Definitions

  • the present invention relates to track grading apparatus, and more particularly to a bogie movable on the track rails and supporting two reference lines in relation to which the rails are leveled.
  • Apparatus of this type is generally known and usually is positioned ahead of track grading machinery, the two reference lines extending from a previously graded track section to the bogie where the front ends of the reference lines are anchored and the bogie being positioned on a track section to be graded.
  • This object is accomplished in accordance with this invention by providing a mechanical drive means for vertically adjusting the contacting or supporting means for the other wire or reference line.
  • An indicating means preferably a pendulum, is provided on the bogie for indicating the relative vertical position of the reference lines and the mechanical drive means is actuated by control means operating in response to this relative verti- Patented Aug. 3, 1965 vertical direction depending on which of the contacts is contacted by the pendulum.
  • both reference lines define at all times a desired reference plane vertically spaced from the track plane and in relation to which the track is graded until its plane is parallel to the reference plane, the ends of the reference lines remote from the front bogie being anchored in a previously graded track section so that they obviously define the proper reference.
  • the apparatus is embodied in a front bogie used in track grading operations wherein the rails are leveled in relation to two reference lines, such as tensioned elongated flexible elements, for instance wires, which define vertical planes with respective ones of the track rails 3 which are mounted on ties 4.
  • the frame 1 of the bogie is mounted on wheels 2 which constitute means arranged for engagement with, and movable on, the track rails 3.
  • the support means for the one tensioned wire 7 and for the other tensioned wire '7 is constituted by peripherally grooved rollers 6 and '6', respectively, which maintain each wire in tensioned condition at a predetermined vertical position.
  • the first roller 6 is freely rotatably journaled in bearing 21 and the second roller 6' is similarly journaled in bearing 21'.
  • Means is provided for interconnecting the first and second wire support means 6, 6, this interconnecting means being constituted by a crossbeam 5 extending transversely of the track and linked at its respective ends to the bearing 21 by pin 22 and to bearing 21 by pin 29.
  • pin 29 is movable in a slot 24 in the connecting lug fixed to bearing 21' whereby the bearing and the interconnecting crossbeam have some transverse play in relation to one another.
  • the crossbeam 5 is afiixed to a pendulum support frame 8 which is mounted on bogie frame 1.
  • Frame 8 carries suspended thereon a pendulum 9 moving between two electrical contacts 10 and 10' mounted on the pendulum frame adjacent respective sides of the pendulum in a plane transverse to the track to indicate the relative vertical po* sition of the tensioned wires and thereby establishing the horizontal inclination of the plane extending through the wires transversely of the track.
  • the end of the pendulum which moves between the Contacts 10, 10' when the relative vertical position of the tensioned wires changes, receives a weak, low-volt age electrical current from an electrical power source 16.
  • the contacts are connected to an electrical control circuit fed by a strong, high-voltage current from electrical power source 15.
  • a grounded relay 11 is connected in the control circuit, branch conductor 10a leading from contact 10 to the relay while contact 10' is connected to the relay by branch conductor 1%.
  • the electrical driving motor 17 is actuated by the electrical control circuit, receiving power from current source 15 which has one terminal connected to the motor by conductor 14 while its other terminal is connected to the mot-or by conductor 13 and branch conductors 12, 12 leading from the relay 11 to the motor.
  • the motor shaft 17 is rotatable in either direction and is rotated in a selected direction depending on whether the relay shunts the current through conductor 12 or 12'. 4 V
  • the means for vertically adjustably mount ing the first roller 6 is manually operable and includes a threaded sleeve 22 threadedly receiving a threaded rod 20 on which bearing 21 is mounted.
  • the rodZtl is moved vertically in relation to the fixed sleeve 22 which isaf- -fixed to thebogie frame 1 by means of bracket 25.
  • the pendulum necessarily assumes a median position be tween the contacts 10 and 10', being out of contact with both. This causes the current supply to the driving motor 17 to be interrupted by relay 11 and the further vertical movement of spindle 2t) and bearing' 21' is thus halted.
  • the direction of the motor shaft rotation depends on whether the motor receives its power through conductor 12' or 12 and the switch to a respective one of these conductors is, closed by the relay, depending on Whether the relay is operated by contact 10 or 10'.
  • the exemplified structural embodiment-of the present invention may be suitsupport means 6 is vertically so adjusted that the reference wire 7 assumes a vertical spacing from its associated rail,- which 'is considered most advantageous for the track grading operation over a plurality of adjacent track sections so that the grading operation may be continued without interruption for some time without resetting the vertical position of wire 7.
  • the additional means for vertically adjustably mount ing the second roller 6' is mechanically drivenunder the control of the above-described electrical control circuit.
  • This additional means includes, in the illustrated embodi-.
  • a guide sleeve 22" affixed to the bogie'frame 1 by means ofbracket 25'.
  • the spindle 20 is freely rotatably journaled in the guide sleeve and held against axial movement therein by flanges 26, 26 engaging the end walls of the guide sleeve.
  • the outer end of the spindle has a threaded portion 27 which'threadedly receives ably varied and modified withoutzinany way departing from the spirit and scope of this invention, as defined in the appended'claims.
  • the apparatus is useful in a variety of track grading systems, regardless as to whether the bogie stands still at the end of a track section being graded or whether the same moves simultaneously with the track grading machine along such a section.
  • tensioned' wire has been specificallyillustrated as the reference line, this'may be constituted, if desired, by light rays, electromagnetic waves and like means constituting straight li j bearing 21'.. Since bearing .21 is held against rotation by crossbeam 5, rotation of the spindle 20', with its threaded spindle portion 27, will cause the bearing 21, with its roller 6','to move up or down, depending on the direction of rotation of the spindle. r
  • Rotation of the spindle is provided by a mechanical drive means illustrated to include the motor shaft 17' and the connecting link rod 19.
  • Universal joints, such as the illustrated ball and cup joints 28, 28, connect the respective ends of the link rod 19 to spindle 20 and to a gear means 18 which transmits the rotation of the motor shaft to the link rod and, thus, to the spindle 20.
  • the relay actuates a switch closing the circuit from high-voltage source 15 to branch conductor 12' and thus causing the motor shaft 17 to rotate in such a direction that the corresponding rotation of spindle 20' raises the wire 7 by distance x, which is the desired vertical position of wire 7' in relation to wire 7.
  • This position may be such that the two wires define a horizontal plane, which is the-case in What is claimed is:
  • control means operating in response to said relative vertical position indicating means of the reference elements and actuating said mechanical drive means.
  • control means includes a pendulum.
  • control means includes electrical contacts mounted adjacent respective sides of said pendulum in a plane transverse to the track, and an electrical control circuit connected to said contacts and actuating said mechanical drive means in a selected vertical direction depending on which of said electrical contacts is contacted by said pendulum.
  • control means operating in response to said relative vertical position indicating means of the tensioned elements and actuating said mechanical drive means, said control means including a pendulum mounted on said interconnecting means and electrical contacts mounted adjacent respective sides of said pendulum in a plane transverse to the track, an electrical drive motor having a shaft rotatable in either direction, an electrical control circuit connecting each of said contacts with said electrical drive motor, closing of said circuit by contact of the pendulum with a respective one of said contacts rotating the motor shaft in a selected one of said directions, and mechanical means for transmitting the shaft rotation to said mechanical drive means.
