Definitions

  • the subject of the present invention is a device for rapid elastic fixing of a railway rail on concrete, or wooden, or plastic sleepers, of the type comprising a rod whose head emerges in the form of an open ring. rests on the rail pad, also centered on its support by a wedge or a saddle, while its other end includes a hooking means associated with the crosspiece making it possible to tension the spring head on the rail pad after the rod has been turned half a turn.
  • the device, object of the invention offers two associated means for tensioning the spring head of the rail fixing rod.
  • a first means which consists in that the upper face of the wedge or saddle is sloping in the extension of the shoe of the rail, so that by maneuvering the rod a half-turn, the head is brought up a low position on the hold or saddle to a higher position on the rail pad to exert strong pressure.
  • a second means which consists in that the hook is formed by a heel of the rod capable of catching on a reserved shoulder in the cross-member or in the saddle, in a downward slope towards the shoe of the rail to play the role of a cam and exerting traction on the spring head when the latter is under pressure on the rail pad.
  • the second means of tensioning the spring rod consists of a steel bowl included in a counterbore made in the concrete or wooden cross member, in line with a bore digging said cross member, to which corresponds an opening made in the centering saddle of the rail on the shoe from which the head of the spring loaded rod rests under tension, after having been turned a half-turn, by the attachment of its heel projecting from an internal rim which the bottom of said bowl with an orifice corresponding to the section of the spring rod reserves.
  • the second means of tensioning the spring rod consists of a shoulder resulting from the difference in the diameters of two bores dug in the centering saddle of the rail fixed by lag bolts if it rests on a crosspiece in wood, or by insulating anchoring sheaths of the kind known under the brand "Plastirail” if it rests on a concrete cross-member, said shoulder allowing the eccentric heel of the rod to be hooked up after being turned ' a half-turn, a block immobilizing said rod spring in the clamping position on the rail pad.
  • the rail centering block has an opening adapted to the sections of the spring rod and its heel and offset with respect to the bore of the anchoring sheath in order to partially close it when the spring rod is introduced therein, while one of its faces, bearing against the side wall of the reserved housing on the cross member, is flared to ensure a slight jamming resulting from the lateral forces exerted by the spring rod, when it is tensioned, against a flange surmounting said wedge.
  • the reference numeral 1 designates the shoe of a railway rail resting on a concrete or wooden cross member 2 by means of an elastic sole 3, or resting on a saddle 4 made of metal or of material reinforced plastic, in known manner.
  • Figures 1 to 3 show a first embodiment of the rail fixing device in question.
  • An insulating anchoring sheath 5 of plastic material of the type known under the brand "Plastirail” is inserted into the concrete cross member 2 at the time of its molding.
  • the rail fixing device consists of a spring rod 9 made of steel wire, or of reinforced plastic. At its lower end, this rod has an eccentric heel 10 with a rounded end forming a hook 112 capable of cooperating with the shoulder 8 of the insulating sheath 5.
  • the section of the hooked part 11 of the heel is slightly smaller than that of the rod itself to allow its passage through the bore 6 of the anchoring sheath 5.
  • the rod 9 forms, at its other end, an open ring 12 extending laterally at an acute angle as illustrated in FIGS. 1 and 3. This ring 12 constitutes the spring head of the rod 9 and may include a flat 13 bearing on the shoe 1 of the rail.
  • a steel bowl 27 with a flared wall is retained, the bottom of which is pierced with an orifice 28 of section corresponding to a bore 29 of the cross member 2 vertically extending the orifice 25 of the saddle 4, reserves a rim 30 hollowed out by a depression 31 which cooperates with the face 11 of the heel 10 of the spring rod 9.
  • the rail 1 also rests on a saddle 4, also fixed to the wooden cross member, or concrete 2 by means of lag bolts, or insulating anchor sheaths known under the brand " Plastirail ".
  • This saddle 4 made of metal or plastic, comprises, at its projecting ends 32, the tensioning means of the spring rod 9. To this end, the part 32 is pierced with a first orifice 33 of oblong section allowing the introduction of the rod 9 and preceding a second orifice 34 of circular section. The difference in the diameters of the orifices 33 and 34 results in a shoulder which can affect a downward slope 35 directed towards the shoe 1 of the rail. This shoulder has a depression, the flanges 36 of which act as non-return stops for the heel 10 of the spring rod. In the clamping position shown in FIG. 7, a shim 37 can be introduced into the orifice 33 of the saddle 4 to immobilize the spring rod 9. However, the shim is not necessary if part of the bore 33 is constricted as shown in FIG. 8, to form two stops ruling over the entire height of the bore and preventing bending of the spring rod 9.
  • the line XX ' represents the pivot axis of the fixing rod 9
  • the line YY' represents the axis of displacement of the spring head 12 of the rod 9.
