Definitions

  • the present invention relates to an adjustable railway rail fastening assembly and methods for use therewith.
  • the need to do this comes principally from three sources; firstly, to allow for less accurate and therefore cheaper construction of the base slab, the final adjustments of the rail head level being made through the fastening; secondly, to allow for subsidence of the slab or the ground beneath it; and thirdly, to allow sections of new rail to be inserted into lengths of worn rail in the case of a break or defect without the need to grind the head of the new rail down to match the head of the worn rail.
  • a baseplate to which the rail is fixed is provided almost entirely to allow for the possibility of rail height adjustment, shims being placed under the baseplate to adjust the height of the rail. This is an expensive option, and it is desirable to find ways in which the need for a baseplate on slab track might be avoided.
  • the rails must be clamped down to keep them from moving or buckling. All spring clips used for anchoring the rail down require some kind of fixture against which they can react. In some cases this is provided by a nut and bolt, in other cases by a component of nominally fixed geometry which is usually referred to as a shoulder. Whichever of the two fastening methods is employed, if the rail is to be raised up from its lowest nominal position, this will be done by placing shims of the required thickness under the rail foot (to save cost the lowest position is usually the nominal position so that the shims are not required unless adjustment is required) .
  • the fastening height relative to the fixed base can be adjusted to some degree while maintaining a given clamping force by tightening the nut or screw used to a lesser or greater extent.
  • the range of adjustment possible in this case may be severely limited by the allowable moment which can be applied to the bolt or screw without fatigue failure. This moment results from the component of the lateral forces which are generated on the track and applied to the fastener through the rail foot, and increases as the rail is raised higher above the base and the moment arm is increased.
  • fastening systems with screw threads have a number of disadvantages which mean that they are not favoured by many railways.
  • the toe At least one part of the clip (the toe) will always bear on the rail, and at least two parts will bear on the shoulder or sleeper. Since the clamping load which the clip applies to the rail depends on the extent to which it is deflected, which in turn depends on the relative heights of these two parts of the assembly, the clamping force will vary as the height of the rail is adjusted. While some small variation in the clamping force is usually acceptable, if the clip deflection becomes too small then the rail clamping force will become unacceptably small, while if it becomes too large then the clip may be over-stressed. Also, as the relative heights of the two parts change, the orientation of the clip will change.
  • clips are usually designed to work best in a fixed orientation. For instance, where a flat bearing surface on the clip toe designed to lie in the same plane as the top of the rail foot no longer does so, its edge may cut into the rail foot or insulator.
  • US 4470543 has means for providing height adjustment which comprise a rotatable core, having an eccentric hole for receiving a centre leg of a spring rail clip, which plugs into a round hole in the centre of an enlarged shoulder. Rotation of the core within the shoulder causes the height of the centre leg relative to the rail foundation to be adjusted.
  • this is not a particularly efficient means of providing adjustment, since the shoulder and core must be quite large even for modest adjustment ranges.
  • the Gray system maintains a constant clip orientation at the expense of requiring a number of different thickness shims which must be put under the clip heel seat.
  • an anchoring device for retaining a spring rail clip in a railway rail fastening assembly, the device comprising an anchoring stem part, fixed to a rail foundation when the device is in use, and a clip-retaining head part, engageable with the said anchoring stem part, for retaining the spring rail clip, the height of the rail clip relative to the rail foundation being determined by the position of the clip-retaining head part of the device relative to the anchoring stem part thereof, wherein adjustment of the position of the said clip-retaining head part relative to the said anchoring stem part is effected by translational movement of the clip-retaining head part.
  • Such an anchoring device allows easier height adjustment whilst avoiding the drawbacks of the Gray arrangement.
  • the device desirably comprises means for inhibiting relative vertical movement between the anchoring stem part and clip-retaining head part thereof when engaged.
  • Such means may be provided on mutually-contacting surfaces of the anchoring stem and clip-retaining head parts and preferably comprise interlocking elements such as serrations.
  • the size of the serrations is preferably chosen so as to ensure that, when'the device is in use, the variation in clamping force of the spring rail clip on the rail is as small as possible with each step change in position of the said clip-retaining head part relative to the anchoring stem part.
  • the height of the rail relative to the foundation can be adjusted in infinitely small steps, this height being determined by the thickness of the shims placed beneath it. The reason for making the size of the serrations small is to restrict the variation in toe load which will result from the step changes in height of the clip-retaining head part.
  • the installed deflection of the clip, and hence the toe load applied to the rail will not vary more than ⁇ 1.5mm or ⁇ 10%.
  • parts having increased frictional resistance may be provided to inhibit vertical movement.
  • the device preferably comprises wedge means, located between respective mutually-opposed portions of the said anchoring stem part and the said clip-retaining head part when the device is in use, for urging the said anchoring stem and clip-retaining head parts together.
  • wedge means located between respective mutually-opposed portions of the said anchoring stem part and the said clip-retaining head part when the device is in use, for urging the said anchoring stem and clip-retaining head parts together.
  • at least one of the said mutually-opposed portions of the anchoring stem part and the said clip-retaining part is provided with means for cooperating with means provided on the said wedge means.
  • Such means may comprise respective regions having interlocking elements, preferably vertical serrations.
  • the length of the serrated region provided on the one mutually-opposed portion of the clip-retaining head part may be shorter than that provided on the wedge means.
  • the clip-retaining head part may be configured to retain any one of a number of different clip types, for example the PANDROL FASTCLIPTM rail fastening clip (which is approximately M-shaped in plan - see EP-B-0619852) or the PANDROL SAFELOKTM rail fastening clip (see US 4313563).
  • the clip-retaining head part desirably comprises a pair of spaced-apart clip-retaining walls for receiving and retaining the legs of such an M-shaped rail clip when the clip is in use, the said anchoring stem part being located between the said clip-retaining walls when the device is in use.
  • a clip-retaining head part suitable for one type of spring rail clip may be replaced by another clip-retaining head part which is configured so as to be suitable for retaining spring rail clips of a different kind.
  • a method of altering a rail fastening assembly using an anchoring device embodying the first aspect of the present invention wherein the clip-retaining head part of at least one of the anchoring devices in the rail fastening assembly is replaced by another clip-retaining head part which is configured so as to be suitable for retaining a spring rail clip of a different kind to that of the first-mentioned clip-retaining head part.
  • the device may be provided with means for locking the anchoring stem part and the clip-retaining head part together during transportation and/or installation, thereby facilitating handling the device. Furthermore, if the clip-retaining head part is designed so as to be able to retain clips in a pre-assembly position (in which the clip does not bear on the rail), installation of the assembly is made even easier.
  • the clip-retaining head part of the anchoring device preferably carries a side post insulator for electrically isolating the clip-retaining head part from a railway rail when the anchoring device is in use.
  • a method of using an anchoring device embodying the present invention which carries such a side post insulator, wherein the said side post insulator is replaced by another side post insulator having an overall thickness, at a part which is to lie between a railway rail and the said clip-retaining head part of the anchoring device, which differs from that of the first-mentioned side post insulator, whereby lateral rail position adjustment may be achieved.
  • the side post insulator may be replaced by another side post insulator having an overall thickness, at a part which is to lie between a railway rail and the said clip-retaining head part of the anchoring device, which differs from that of the first-mentioned side post insulator.
  • small lateral adjustments may be provided for by side post insulators of varying thickness, allowing the position of clip toe contact on the rail foot to vary.
  • a method of adjusting lateral rail position in a rail fastening assembly using an anchoring device embodying the present invention wherein the clip-retaining head part of at least one of the anchoring devices in the rail fastening assembly is replaced by another clip-retaining head part having an overall thickness, at a portion lying between the rail foot and the anchoring stem part of the device, which differs from that of the first-mentioned clip-retaining head part.
  • the said clip-retaining head part may be replaced by another clip-retaining head part having an overall thickness, at a portion which is to lie between the rail foot and the said anchoring stem part of the device, which differs from that of the first-mentioned clip-retaining head part.
  • larger lateral adjustments may be provided for by additionally supplying alternative shoulder heads of differing geometry, such that the dimension between their serrated back face which bears on the serrated face of the stem and their front face against which the side post insulator bears varies.
  • Three sizes of shoulder used in the correct combinations would allow for lateral rail position adjustment in three steps without variation in clip toe contact point relative to the rail foot.
  • the said clip-retaining head part may be fastened to the said anchoring stem part, for example by means of a bolt.
  • a rail fastening assembly embodying the present invention the rail, which sits on a resilient pad, is secured by a pair of fastenings, each of which consists of an M-shaped spring rail clip, a rigid anchoring stem part which is fixed into the base and a rigid adjustable shoulder or clip-retaining head part which retains the M-shaped spring rail clip.
  • Each fastening of the assembly is provided with two electrical insulator parts (side post and toe) which separate the rail from the clip and anchoring device.
  • the anchoring device has a locking part which retains the shoulder to the stem. After the locking part has been loosened or removed, the adjustable shoulder (clip-retaining head) can be moved vertically up and down in relation to the fixed (anchoring) stem part.
  • the locking part is reapplied once the adjustable shoulder is in its correct vertical position.
  • the adjustable shoulder part interlocks with the stem, and is held in place by the moment caused by the unbalanced forces applied to it by the spring clip when it is engaged.
  • the locking part prevents rotation of the adjustable shoulder relative to the stem under the action of this moment.
  • Serrated faces are provided on the two interlocking faces to promote high friction. The serrations are as small as possible to allow as small a variation in clamping force as possible with each step change in shoulder position.
  • the size of vertical adjustment step is infinitely small, being governed by the thickness of shims placed under the pad.
  • Figure 1 shows a railway rail fastening assembly comprising a flange-footed railway rail 1, supported by a concrete rail foundation 2, and a pair of rail fasteners comprising respective spring rail clips 3 and anchoring devices (or shoulders) 4.
  • Each anchoring device 4 carries a side post insulator 5 for electrically isolating the anchoring device from the adjacent rail.
  • the rail 1 is cushioned by a rail pad 6 located between the foot of the rail and the underlying rail foundation 2.
  • Each spring rail clip 3 carries a toe insulator 7 for electrically isolating the clip 3 from the rail.
  • the anchoring device 4 will now be explained in more detail with reference to Figures 2a and 2b, which show perspective views of the anchoring device 4 from the side ("front") which will be closest to the rail when the anchoring device is in use, respectively with and without the spring rail clip 3 installed therein, and Figures 2c and 2d, which show corresponding perspective views of the anchoring device 4 from the side ("rear") which will be furthest from the rail when the anchoring device 4 is in use.

  • the top portion 400 comprises a pair of spaced-apart upstands 405 connected at their bottom edges by a base member 406, which adjoins the bottom portion 401, and at their top edges by a reinforcing (cross-bar) portion 407, which is provided to add strength to the top portion 400.
