Definitions

  • the present invention relates to a clamping means and sleeper assembly according to the preamble of claim 1.
  • a pivotable clamping means enables extremely simple attachment of a rail to a sleeper and requires only one tool which can turn the clamping means about its axis. Thus, apart from the actual turning tool, there are no loose parts whatsoever. If a rail is to be replaced the clamping means need only be turned from its contact position, thus making replacement extremely easy.
  • a unit can be utilized on rails already laid, said unit being displaced along the rail, thereby turning the clamping means to abutment with the rail foot or turning it out of contact with the rail foot.
  • the spring may consist of a helical spring or some other spring device like a rolled laminated spring standing on edge, cup springs, ring springs or Archimedes springs arranged about the axis of oscillation of the clamping means.
  • the spring itself is so dimensioned that when the clamping means is in contact with the foot of the rail, a pressure is obtained which is sufficient to retain the rail in position when it is used for traffic and at fluctuations in temperature.
  • the temperature in winter may be -50°C and in summer it may be over 40°C.
  • the lower end of the spring may be extended so that it is in contact with the flange or tongue of the clamping means.
  • the clamping means may cooperate with a snap device so that when the clamping means is in operating position, i.e. in contact with the foot of the rail the snap device will come into operation. In all other positions the snap device will be out of operation.
  • the clamping means may be arranged on a plate secured on the upper side of a sleeper.
  • the axis of oscillation of the clamping means may also be secured inside the sleeper itself, either by means of a tapping arrangement or by grouting. According to the latter alternative, the sleeper itself is made of concrete.
  • Fig 1 shows a rail 1 with head 2, web 3 and foot 4.
  • the foot rests on a sleeper 5.
  • the sleeper is made of concrete and has a shaft 6 grouted into it, the shaft being provided with cavities 7.
  • the function of the cavities is to fix the position of the shaft 6 in the sleeper when the concrete has solidified.
  • the lower end of the shaft may be optionally desired provided the shaft 6 is permanently secured when the concrete has set.
  • a unit 9 is applied about the shaft 6, suitably resting on a plate shown in Fig 4 and designated 15. Said plate 15 is suitably permanently joined to the shaft 6.
  • the unit 9 is provided with an aperture enabling it to be pivoted about the shaft 6.
  • the unit 9 is provided with a radially outwardly directed tongue or flange 10.
  • a helical spring 11 is provided in the clamping means. One end of said spring 11 is abutting against the unit 9. The other end of the helical spring acts on a plate 12 riveted to the shaft 6 which limits its upward movement.
  • Reference sign 13 designates the head of a screw or rivet.
  • the lower end 14 of the spring is pulled out and is in contact with the tongue, as shown in Figures 2 and 3.
  • the spring 11 is dimensioned so as to achieve a pressure on the tongue 10 that is sufficient to retain the rail when it is subjected to the stresses caused by traffic and also by temperature fluctuations.
  • Figures 2 and 3 show the clamping means in operation with its tongue in contact with the rail foot and with the tongue out of its retaining position.
  • the actual unit 9 and sleeper 5 may be so designed that when the unit assumes the position shown in Fig 2, the snap device will come into operation thereby positioning the unit correctly to carry out its retaining function. It is clear from the drawings that the unit 9 can be turned to an unlimited extent about its axis 6.
  • the unit 9 with parts 6-8 and 10-13 is normally in the form of a prefabricated unit and is therefore easy to apply on a sleeper. If a clamping means is damaged only the head of the screw or rivet need be ground off. Damaged parts can then easily be replaced and a new head welded on.
  • Fig 4 shows a unit which functions in exactly the same manner as that illustrated in the previous figures but which differs in that the axis 6 is a tubular shaft secured to a plate 15 attached to the sleeper 5 by means of a screw joint 16.
  • the shaft 6 may comprise a pipe with a screw running through it and penetrating into the sleeper 5 below, thereby securing the clamping means to the sleeper.
  • a threaded sleeve can be grouted into the sleeper 5 if it is made of concrete.
  • the unit may then be designed so that when it passes a unit 9 it either turns this to achieve contact with the rail foot or to disengage it from the rail foot.
