Definitions

  • the present invention relates to a new shoe (or stop) usable for producing an elastic fixing of a rail on a cross member and, more particularly, on a reinforced concrete cross member.
  • connection of the rails to the sleepers or other supports includes guides or lateral stops, the main drawback of which is the reciprocal wear of the rail and the stop.
  • This wear is obviously not favorable to the preservation of a good geometry of the track and, in certain cases, it leads to a partial deterioration of the rail which makes the latter non-reusable.
  • the guides can have other drawbacks such as too great rigidity which makes them difficult to use with concrete sleepers and for elastic metal stops insufficient resistance to large forces which are developed during the passage of convoys in curves small radius.
  • the present invention relates to a rail fastener using the known elastic blade described in the patent.
  • French No 2,481,334 and a shoe said shoe comprising a core 11 which is inserted in the loop 4 of said blade, a body integral with said core provided with an opening for the passage of a clamping member and a heel 6 arranged to constitute a stop against the edge of the rail pad, and an extension 7 disposed above the rail pad, said shoe being characterized in that its upper face comprises a boss 8 located substantially at the edge of the rail pad, said boss separating two recessed parts.
  • the core 11 of the shoe is used to attach and place said shoe under the elastic blade.
  • the extension 7 of the shoe above the shoe of the rail is used to achieve complete isolation of the blade from the rail.
  • the boss 8 is used to control the clamping of the blade on the shoe and cause a blocking of the shoe stop against the rail pad.
  • the fastener according to the invention includes a blade L and a shoe S. It is used to fix the rail R on the cross T, an elastic and insulating sole I being disposed between the rail R and the cross T .
  • the blade L made of spring steel has an orifice 1 for the passage of the clamping member 2 shown in FIG. 2, one end 3 resting on the shoe S and one end wound in the form of a loop 4 which serves as articulation with the cross on the one hand and with the shoe S on the other.
  • the shoe S made of polyamide, polyacetal resin, or other material of the same elasticity comprises: an orifice 5 coaxial with the orifice 1 of the blade for the passage of the clamping member 2, a heel 6 forming a lateral stop for the rail, a extension 7 which isolates the blade L of the rail R and has a boss 8 leaving a clearance J of a well-defined value between the blade L and its shoe S, a support 10 arranged for the blade, a recess 9 which separates the support 10 from the boss 8 and a core 11, the shape of which adapts to the partially cylindrical interior shape of the loop 4. Between the core 11 and the boss 8, the upper face 12 of the shoe S is slightly curved. The underside 13 of the shoe S does not come into contact with the crosspiece T and has a small shoulder 14 which serves to position the insulating sole I.
  • the clamping of the blade L by the clamping member 2 brings it into contact with the boss 8.
  • the stroke J which brings it into contact with the boss corresponds to a precise clamping force on the support 10 of the shoe S and therefore on the shoe of the rail.
  • the purpose of the recess 9 and the curving of the upper face 12 of the shoe S is to avoid distorting the force applied to the rail by imprecise contacts of the blade with the shoe during tightening.
  • the shoe S can be assembled to the blade L by a fold 15 of the shoe beyond the support 10 and the flanges 16 and 17 which appear in FIG. 3.
  • the present invention applies to the fixing of the rails on the sleepers or any other support and more particularly on the concrete supports of the railway tracks, in curve of small radius.
