Definitions

  • the anchoring device may consist either of a sheath-bolt assembly or of a stud-nut assembly.
  • the clip can assume two distinct positions, a standby position away from its mounting position on the rail and a mounting position where the elastic clip is mounted bearing against said rail heel.
  • the transition from the rear position to the front position of the elastic clip is done by unscrewing the anchoring device a little to release the elastic clip from its initial factory tightening then by moving attaches it perpendicular to the direction of the rail, i.e. forward.
  • the lag screw or nut of the anchor device is then screwed back on.
  • a rail fastening system intended to be mounted laterally with respect to said rail and fixed to a track support, comprising a lateral abutment, forming a base, comprising a bearing edge intended to come into contact with the edge of a rail base, an elastic clip made of metal wire and an anchoring device cooperating with said elastic clip and capable of being secured to said track support by passing through a hole in said lateral abutment, in order to under stress said elastic attachment when part of the latter rests on a rail heel, characterized in that said elastic attachment comprising a central loop substantially in the shape of a U with which said anchoring device cooperates, said lateral abutment extends in its central part from said bearing edge by a base which comprises in its middle a raised block for guiding said central loop, perpendicular to said bearing edge of the stop l lateral, in that this guide block has a width corresponding to the spacing of said central loop so that said elastic fastener is subject to move only in a direction perpendicular to said
  • the upper face of the lateral stop also has two ramps, on the rear side, on either side of the guide block so that said elastic fastener can progress more easily towards the heel in a slightly upward path, until entering in contact with him.
  • the head of the anchoring device mentioned above is the head of the lag screw in the case where this anchoring device consists of a lag screw and a sheath.
  • this anchoring device consists of a stud and a nut
  • said anchoring head consists of the nut itself.
  • the anchoring device 21 is capable of being secured to the track support 15 by passing through a hole 27 of circular section of said lateral abutment.
  • the tightening of the anchoring device puts the elastic clip 17 under stress when a part of the latter rests on a rail heel 31. ci which rests on the crosspiece; so this skate is essentially consisting of two heels 31 extending on either side of the central part of the rail. Each fastening system described cooperates with such a heel 31.
  • the lateral stop 19, forming a base is made of rigid plastic material and comprises a bearing edge 35 intended to come into contact with the edge of a heel 31 of the rail. From this front bearing edge, the lateral abutment is extended in its central part by a base which comprises in its middle a raised block called hereinafter guide block 39.
  • the guide block of constant width, is perpendicular to said bearing edge. Consequently, when the bearing edge 35 is in contact with the edge of the heel 31, the guide block 39 is perpendicular to the rail 13.
  • the clip 17 of steel wire has two lateral branches 41 intended to come into contact with a heel 31 of the rail and a central loop 42, directed rearward, substantially U-shaped with parallel branches 45. As will be seen later, the anchoring device 21 cooperates with this central loop 42 for the stressing of the elastic fastener 17.
  • the guide block 39 has a width corresponding to the spacing of the two parallel branches 45 of the central loop 42 so that said elastic fastener is subject to move only in a direction perpendicular to said bearing edge 35, that is to say perpendicular to the rail, being guided by the side walls 49 of said guide block during its passage from the standby position (rear) remote from the rail to a mounting position where the two side branches 41 rest on a heel of the aforementioned rail.
  • the hole 27 is formed vertically in the guide block 39.
  • the flat upper surface 51 of said guide block constitutes a stop for limiting the tightening of the anchoring device. In the case where the head of the lag screw is completed by a washer 23 like that of the figure 4 , it is the washer which bears both against the upper face 51 of the guide block and which comes into contact with the two parallel branches 45 of the central loop.
  • the upper face of the lateral stop has two ramps 55a, 55b on either side of the guide block, on the rear side. These two ramps with a rounded bottom receive the two branches 45 of the central loop. In this way, the elastic fastener can progress more easily towards the heel, at the time of assembly, in a slightly upward path until it comes into contact with said heel.
  • lugs 57 On the side of the support edge 35, towards the rear and at the ends of the latter, are defined lugs 57 for positioning the elastic fastener in the standby position. These lugs, located towards the rear with respect to the edge 35 are connected to the lateral stop by curved portions matching the branches of the elastic fastener.
  • the track support 15 is of the type comprising a flat-bottomed groove 60 capable of accommodating a rail 13.
  • this groove is a little wider than the rail shoe 33 and each side stop plastic material, comprises at least one projecting marginal rib 62, oriented downwards, in the extension of the support edge and capable of being inserted between an edge of the rail heel and the corresponding edge of said flat-bottomed groove 60. This facilitates the positioning of the lateral stop 19 along the rail.
  • the track support also advantageously comprises a trough 65 or similar hollow extending parallel to the location of the rail and the lateral abutment comprises a rear rib 67 projecting from its lower surface and capable of engaging in said trough to also contribute to the correct positioning of the lateral stop and consequently of the guide block 39 so that the latter is perpendicular to the direction of the rail.
  • the concrete sleeper comprises two such chutes 65, on either side of said flat-bottomed groove 60.
  • the rail 13 is placed at the bottom of the groove 60 and bears on said crosspiece by means of a sole 69 made of elastomer with a plastic material.
  • the height h of the guide block is advantageous for the height h of the guide block to be greater than or equal to the diameter of the metal wire which constitutes the elastic clip.
  • the height h be somewhat greater than the wire diameter of the fastener so that a clearance J ( figure 6 ) remains, after tightening "block" of the lag screw, between the fastener and the lateral stop, so that the branches 45 of the fastener can work in bending and torsion.
  • the branches 41 can elastically accompany the vertical movements of the rail during the passage of a train.
  • the washer 23 is placed under the head 25 of the lag bolt and comes into contact, after assembly, both with the upper surface 51 of the guide block and the branches 45 of the central loop of the elastic fastener.
  • the sole is traditionally made of plastic material, therefore insulating.
  • the washer 23 can also be made of plastic material, which facilitates the electrical insulation of the rail.
