Definitions

  • ABSTRACT An improvement for a railway switch for vignoles rails of the type comprising a frog tip and wing rails arranged for swinging movement, one of the wing rails engaging the frop tip in the respective end positions and being maintained in engagement with the frog tip by movable supporting members supporting the wing rail in direction to the rail axis and being connected with the railway sleepers and preferably acting on the rail web, the improvement being that the supporting members are supported independently on the actuating means for the wing rails and rested on sliding plates connected to the sleepers.
  • check rails For forcing the wheel pairs in the desired direction of travel and for preventing the frog tip from becoming damaged so-called check rails are arranged adjacent the outer rails, said check rails pulling away the wheels from the frog tip and thereby exerting a so-called shock which in turn impairs the comfort of passengers.
  • the invention now refers to a railway switch for Vignoles's rails comprising a frog tip and wing rails arranged for swinging movement. noting that in the end positions one of saidwing rails is engaging the .frog tip and supported in itsposition in direction to the rail axis by movable supporting members being connected with the railway sleepers and, preferably, acting on the rail web.
  • the invention essentially consists in that the supporting membersare supported independently on the actuating means for the wing rails and rested on sliding plates connected to the sleepers and, preferably, moved with a phase-shift relative to the ad justment movement of the rails.
  • the supporting members In view of the supporting members being rested on the sliding plates connected to the sleepers, the respective forces are transmitted directly into the sliding plate so that the wing rails are firmly supported in a reliable manner.
  • the present invention is of particular advantage for a railway switch for Vignoless rails in which the wing rails are actuated, e.g., by means of a brace tip lock, with a phase shift such that the wing rail being spaced from the frog tip is moved prior to the wing rail just contacting the frog tip.
  • the arrangement is, according to the invention, such that the supporting members provided for supporting one of both wing rails are coupled to the supporting members provided for supporting the other of both wing rails. In this manner, during swinging movement of the wing rails the respective supporting members are automatically brought into their supporting position without necessitating an additional actuating means.
  • the supporting members are formed by levers pivotably connected to the sleepers or, respectively, to sliding plates connected to the sleepers. When being in supporting position, these levers assume a self-locking position, being, for example, in self-locking position directed perpendicular to the longitudinal direction of the rail.
  • the actuating links are completely relieved of load in operating position.
  • all supporting members cooperating with'one of both wing rails are coupled with one another by means of actuating links for being moved in the same sense.
  • the frog tip is formed as a two-arm lever, one arm of which is supporting the wing rail and the other arm of which is coupled to the other wing rail via a coupling member.
  • FIG. 1 represents a top-plan view of the frog area of a railway switch
  • FIG. 2 illustrates a section along line Il-II of FIG. 1;
  • FIG. 3 represents a section along line lIIIII of FIG. 1;
  • FIG. 4 illustrates the arrangement of rails within a railway switch according to the invention.
  • the stationarily arranged frog tip has the reference numeral 1 and the movable wing rails have the reference numerals 2 and 3.
  • the wing rail 2 In the position shown in FIG. I, the wing rail 2 is engaging the frog tip 1 and is, therefore, in the position to support rolling wheels.
  • a push rod 4 or a so-called brace tip lock is correspondinglymoved.
  • This brace tip lock consists of said push rod 4, the locking members 5 and, respectively, 6 and the locking braces 7 and, respectively, 8 which are pivotally connected to the wing rails 2 and, respectively, 3 by means of bolts 9 and, respectively, 10.
  • locking brace 8 In the position shown in FIG. 1, locking brace 8 is engaging a recess 12 provided in push rod 4. The locking brace 8 is maintained within the recess 12 of push rod 4 by the locking member 6.
  • wing rail 3 When moving push rod 4 in direction of arrow 11, wing rail 3 is moved in direction of arrow 11 by means of locking brace 8 and bolt until locking brace 8 emerges from locking member 6 and is forced out of recess 12, as is shown for locking brace 7.
  • wing rail 3 is brought into contact with frog tip 1.
  • the dove-tailed head of locking brace 7 is entering the recess l3 of push rod 4 and finally assumes a position in which the head of locking brace 7 can be drawn into the locking member 5.
  • wing rail 2 is lifted from frog tip I by means of bolt 9.
  • both wing rails are moved simultaneously in direction of arrow ll.
  • the wing rails are moved with a phase-shift such that the wing'rail being distant from the frog tip (the wing rail 3 in the drawing) is moved leadingly relative to the wing rail being in engagement with frog tip 1 (wing rail 2 in the drawing).
  • sliding plates l5 and 15' are fixed and arranged for slidingly supporting the wing rails 2 and 3 during adjusting movement thereof.
  • Cylindrical sockets and, respectively, pivot pins 16 and 17 are welded to sliding plate 15, two-arm levers l8, l9 and, respectively, 20, 21 being arranged for pivotal movement on said pivot pins.
  • a coupling member 23 is pivotally connected to lever arm 19 at 22 and furthemiore pivotally connected to the rail base 25 of wing rail 3 by means of a connecting pin 24.
  • a coupling member 27 is pivotally connected to lever arm 21 at 26 and pivot ally connected to the rail base 29 of wing rail 2 by means of a connecting pin 28.
  • the other lever arms 18 and are representing the supporting members.
  • Pivot pins and, respectively, cylindrical sockets 29 and, respectively, 30 are welded to sliding plates 15' and single-arm levers 31 and, respectively, 32 are pivotally supported by said pivot pins. Said levers 31 and, re-
  • 32 equally represent supporting members.
  • Levers 31 are mutually connected by a coupling rod 33, while levers 32 are connected by a coupling rod 34.
  • Connecting rods 37 and, respectively, 38 are pivotally connected to these coupling rods at 35 and, respectively, 36 and furthermore connected at 39 and, respectively, 40 to levers l8 and, respectively, 20.
  • wing rail 2 In the position shown in FIG. 1, wing rail 2 is contacting frog tip 1 and is in the position to carry passing wheels.
  • lever 18 and all levers 31 assume an approximately perpendicular position relative to the longitudinal direction of the wing rail and are supporting this wing rail in direction to frog tip 1.
  • the lever 18 and the levers 31 are assuming a selflocking position so that the supporting forces are transmitted to the pivot pins 16 and 29 whereas the actuating links are substantially completely relieved of any load.
  • wing rail 2 In the position shown, wing rail 2 is reliably supported against laterally acting forces.
  • wing rail 3 When moving push rod 4 in direction of arrow 11, wing rail 3 is moved in direction to frog tip 1 while wing rail 2 is still unmoved. During this movement, two-arm lever l8, 19 is rotated in clock-wise direction by means of coupling member 23 and releasing wing rail 2. Likewise, levers 31 are rotated in clock-wise direction by means of connecting rod 37 and coupling rod 33 and, therewith, equally releasing wing rail 2. On further movement of push rod 4, wing rail 2, now being released by levers 18 and 31, is lifted off the frog tip 1.
  • Two-arm lever 20, 21 being coupled via coupling member 27 to wing rail 2 is rotated during movement of wing rail 2 in counter-clockwise direction until lever arm 20 assumes a position in which this lever arm has a direction approximately perpendicular to the longitudinal direction of the wing rail and in which this lever arm is supporting wing rail 3 in direction to frog tip 1.
  • levers 32 are rotated in counterclockwise direction under the influence of connecting rod 38 and coupling rod 34 into their supporting position in which these levers 32 assume a position perpendicular relative to the longitudinal direction of the wing rail. In this position, wing rail 3 is supported against laterally acting forces and secured in its engagement position on frog tip 1.
  • levers 18, 31 and 20, 32 are acting on the rail web, and the connecting rods 37 and, respectively, 38 as well as the coupling rods 33 and, respectively, 34 are pivotally supported at a level above these levers.
  • This provides the advantage that the connecting rods, the coupling rods and also the levers are arranged as high as possible so that they can not be blocked by snow and ice.
  • Coupling rods 33 and 34 are pivotally connected to levers 31 and, respectively, 32 near the free ends thereof, so that the cou pling rods 33 and 34 are located close to the rails and do not representan obstacle when effecting maintainance work by using track packing machines.
  • the pivot pins 39 and 40 are rigidly connected to connecting rods 37 and 38 and pivotally guided in eyes provided in levers l8 and 20.
  • the coupling rods 33 and, respectively, 34 are connected with levers'3l and, respectively, 32 by pivot pins 41 and, respectively, 42.
  • the heads 43 and, respectively, 44 of these pivot pins are formed by plate members which are clamped between threaded nuts 45 and, respectively, 46 (FIG. 3).
  • threaded members 47 and, respectively, 48 are welded into coupling rod 33 and, respectively, 34. In this manner, an exact adjustment of the position of levers 31 and, respectively, 32 is made possible.
  • Pivot pins 16 and 29 and, respectively 17 and 30, as well as pivot pins 39 and 48 and, respectively 40 and 42 may be pivotally supported in prestressed bushings of synthetic resin material so that no maintainance work is necessary.
  • the wing rails are supported in lateral direction. Additionally, there may be provided abutting ridges 49 which overlap opposing sides of the rail bases 25 and 29 of the wing rails and are welded to sliding plate 16.
