Definitions

  • the chief object of the present invention is to provide a fixation device of this kind which absorbs vibrations and gives a high coefficient of safety.
  • the base flange of the rail rests upon a sole of rubber or another resilient material, preferably fitting tightly in a housing of the sleeper, and the web of the rail is held between two clips with the interposition of packings of rubber or another resilient material, of L-shaped cross section in such a manner that the pressure received from the clips is applied both to the web and to the upper face of the base flange of the rail, the edges of said base flange preferably remaining free.
  • the resilient packings are provided with flanges forming abutments to hold the clips and to avoid any slipping thereof.
  • the clips are cup-shaped and provided with ribs transverse to the rail.
  • FIG. 1 is a cross section of a rail and its fixation device on a sleeper, the left hand half portion of said FIG. 1 being a cross section on the line AA of FIG. 2 and the right hand half portion a cross section on the line BB of FIG. 2;
  • FIG. 2 is a longitudinal vertical section corresponding to FIG. 1, the left hand half portion of FIG. 2 being a section on the line D-D of FIG. 1 and the right hand half portion a section on the line CC of FIG. 1;
  • FIG. 3 is a part sectional view of rubber packing of the device of FIGS. 1 and 2;
  • FIG. 4 is a side elevation of said rubber packing
  • FIG. 5 separately shows, in plan view, one of the fixation clips of the fixation device.
  • the base flange 2 of the rail is supported by a thick rubber sole 3 which preferably, as shown, is engaged in a housing 4 provided in sleeper 1, so as to prevent any slipping of said sole.
  • This housing 4 the edges of which are shown in FIGS. 1 and 2 at 5 and 6 extends into sleeper 1 to a depth sufficient with respect to the housings intended for the fixation of the clips which will be hereinafter referred to.
  • sole 3 is advantageously provided with channels or grooves 7 to improve the flexibility thereof.
  • clips 8 intended to exert a pressure laterally both upon the web 9 and upon the upper surface 10 of the base flange of the rail.
  • rubber packings 11, of L-shaped cross section which bear both upon the web and upon the base flanges of the rail.
  • the side edges 12 of the rail base flange are free.
  • the clips are made of any suitable shape to permit of exerting the desired presurc upon the above mentioned L-sha-ped surfaces.
  • Packings 11 are advantageously provided with grooves 25 increasing their flexibility.
  • the clips are cup-shaped, with transverse partitions or stiffening ribs such as 14, 15, 16, 17 extending as far as the bottom 18 of the clip.
  • the clip is divided into three chambers the central one of which is provided with an oblong hole 19 for the passage of a bolt 20.
  • the bottom 18 of the clip is stepped at 26 so as to fit against the edges 27 of packings 11.
  • vRain in the above mentioned chambers can be evacuated through hole 19 or through holes 21.
  • the device according to the present invention when the bolts such as 20 are tightened and provided that the re spective thicknesses of sole 3 and packings 11 are suitably calculated, permits of ensuring and maintaining contact of the resilient elements with the clips and the base flanges of the rails when a train, even very heavy, passes along the rails, fixation of said rail being thus obtained without possible tipping of the latter.
  • the device according to the present invention reduces the noise, keeps exactly the distance between the rails of the track and permits of establishing track circuits.
  • a device which comprises, in combination:
  • said clips each having an upwardly and outwardly inclined side wall respectively corresponding to and adapted to cooperate with an upwardly and outwardly inclined side wall of said support housing, whereby tightening of said fastening means urges said clips downwardly and inwardly so that said clips apply pressure downwardly and inwardly against said resilient packings.
  • a device according to claim 1 wherein the clips are cup-shaped, and said stiffening means comprise ribs transverse to the rail.
  • a device wherein the cupshaped clip is divided into three chambers, and said fastening means comprises a bolt engaged in the central chamber for fixation to said support.
  • a device according to claim 2 wherein said cupshaped clip is provided with holes for the evacuation of rain water.
  • a device according to claim 1 further including a clips are fitted.
