Definitions

  • the present invention relates to a railway rail pad.
  • the clip can be driven off the rail back into the pre-assembly position, or further into an “insulator-change position” in which the clip does not overlie the sidepost insulator, so complete withdrawal of the clip from the shoulder is not necessary.
  • Such clips are sometimes known as “switch-on/switch-off” clips.
  • Rail fastening assemblies as described in the applicant's patent applications WO93/12294, WO93/12295 and WO93/12296 have a rail pad which underlies the foot of the rail, providing cushioning and electrical insulation, and electrical “sidepost” insulators which are located between the rail foot and the front face of an adjacent shoulder. Although once installed on a sleeper in the factory or in track the sidepost insulators are held in place by the rail clip, the installation process is comparatively difficult and costly.
  • a rail pad for use beneath a railway rail in a rail fastening assembly as cushioning and/or electrical insulation, the pad having a major face providing a rail seat portion on which the foot of the railway rail sits when the rail pad is in use, wherein the rail pad further comprises two upstanding portions, integrally formed with the rail seat portion along opposite edges thereof, so as to extend along only a central part of the edge.
  • the upstanding portions are preferably made of electrically-insulating material and are shaped and arranged so as to form insulation members for electrically insulating the rail foot from rail clip anchoring devices located one on either side of the rail when the pad is in use.
  • the pad and side post insulators as one part, rather than two separate insulators and a pad, the unit can be produced more cheaply that the three separate parts. Because it is one part, it is also easier to fit than three separate parts—both in the sleeper factory and in the field.
  • the sidepost insulator members and rail seat portion are formed as one part, the rail pad will contribute to good overall electrical resistance of the assembly. In particular, by making a good seal between the insulator members and the rail seat portion, electrical insulation can be improved, as compared to having separate pad and insulator parts, because there is no path for moisture to be drawn through.
  • the insulation members are formed of a material having greater resilience to damage than the rail seat portion of the pad, since these portions are subject to much higher pressure than the rail seat portion, due to the lateral loads which are transmitted through them to the shoulder.
  • the insulation members may be made of nylon and the rail seat portion of EVA.
  • the upstanding portions are preferably attached to the rail seat portion in such a manner as to be readily detachable therefrom.
  • the upstanding portions desirably mechanically interlock with the said rail seat portion.
  • the pad is such that the side post elements can be torn away from the rail seat portion after the pad is installed in track, thereby eliminating the need to jack the rail and the cost of replacing the rail seat portion of the pad.
  • the new replacement parts would be separate individual side post insulators, that would not need to connect to the rail seat portion of the pad. It would not be a problem if one or both of the insulator members became detached from the rail seat portion in service, through wear or mechanical action rather than through deliberate action, as once in place the rail seat portion and insulating members of the pad can function separately, as in the prior art.
  • the width of the said rail seat portion can conform to a range of rail seat widths.
  • this is achieved by providing the rail seat region of the pad with a concertinaed section which can be stretched or squeezed between a minimum width and a maximum width, so as to adjust the overall width of the rail seat portion.
  • the pad is sized to fit a maximum railseat, and would be a ‘squash fit’ into a narrower railseat.
  • a railway rail fastening assembly comprising two railway rail fastening clips, two anchoring devices for retaining respective ones of the rail fastening clips when installed therein and a rail pad embodying the first aspect of the present invention, located between the two anchoring devices, wherein each insulation member of the pad is formed with a shelf which extends over a portion of that anchoring device which is adjacent thereto, the shelf being overlain by the rail clip installed in the anchoring device when the clip is in a pre-assembly position in which the clip does not overlie the rail seat portion of the pad.
  • the pad is held in place by the clip.
  • FIG. 1 shows a rail pad embodying the first aspect of the present invention, in which FIG. 1A is a perspective view from above, FIG. 1B is a plan view from above and FIG. 1C is a cross-sectional view taken along the line C-C in FIG. 1B .

  • FIG. 4 shows a railway rail fastening assembly embodying the second aspect of the present invention, in which FIGS. 4A and 4B show the assembly in a side view in which the clip is in a pre-assembly position with respect to the rail, FIG. 4B being a part cross-sectional view, FIGS. 4C and 4D show another side view of the assembly in which the clip is bearing on the rail, FIG. 4D being a part cross-sectional view, FIG. 4E shows a rear view of the assembly and FIG. 4F shows a perspective view of the assembly.
  • Rail pad 4 is made of electrically-insulating material and is substantially rectangular in outline, having a first major face 41 and a second major face 42 opposite to the first major face, the first major face 41 providing a rail seat portion 43 on which rows of studs 43 a are provided, the rail seat portion 43 providing cushioning between the underside of the rail foot and the underlying concrete sleeper.
  • the rail seat portion 43 is also provided with a concertinaed section 43 b which extends across the rail seat portion 43 in a direction parallel to the axis of a rail when seated thereon, the concertinaed section serving to allow the pad to conform to rail seats of varying widths, within a certain range.
  • the four corners of the rail pad constitute ears 44 between which there are defined two recesses 45 which receive respective shoulders 1 , providing longitudinal location and creep resistance.
  • each insulating portion 46 Integrally formed with the rail seat portion 43 and the ears 44 are sidepost insulator portions 46 for insulating the rail from the shoulder 1 , each insulating portion 46 projecting upwardly from the first major face 41 and having a substantially horizontal shelf 47 which extends away from the rail seat portion 43 such that, when the rail pad 4 is in position between two shoulders 1 , the shelf 47 will extend over a portion of the shoulder 1 and will be overlain by the toe portion 34 of a clip 3 installed in the shoulder 1 .
  • the sidepost insulator portions 46 which may be formed of nylon, may be cored out, the cored-out parts of the insulator portions 46 being filled with the material forming the rail seat portion 43 , for example EVA.
  • the anchoring device 1 shown in FIGS. 2A to 2G comprises a head 1 A from the underside of which downwardly project a stem part 1 B and two spaced-part tangs 1 C.
  • the stem part 1 B comprises a substantially Y-shaped stem 100 , connected to the underside of the head 1 A at the ends of upper arms 101 of the Y, and a bent part 102 at the other end of the Y for resisting withdrawal of the stem from the concrete in which it is embedded when it is in use.
  • FIG. 1 comprises a head 1 A from the underside of which downwardly project a stem part 1 B and two spaced-part tangs 1 C.
  • the stem part 1 B comprises a substantially Y-shaped stem 100 , connected to the underside of the head 1 A at the ends of upper arms 101 of the Y, and a bent part 102 at the other end of the Y for resisting withdrawal of the stem from the concrete in which it is embedded when it is in use.
  • the underside of the shoulder 1 may be provided with one or more webs 1 D connecting the stem 100 of the shoulder 1 to its head 1 A, instead or in addition to the tangs 1 C (not shown in FIG. 2H ), for assisting in preventing the shoulder 1 tipping forward when a clip is driven into it.
  • the head 1 A of the anchoring device 1 comprises two spaced-part walls 10 , connected together at one end of the head 1 A, at the bottom of the walls 10 , by a connection portion 14 .
  • the top surface of the connection portion 14 is downwardly inclined and forms a ramp 140 , while the front surface of the connection portion 14 forms the front face 12 of the shoulder 1 .
  • the end of the walls 10 at the front end of the head 1 A are connected to the front face 12 of the shoulder by curved portions 13 .
  • the walls 10 extend outwardly at their tops to provide respective clip-engaging surfaces 11 provided with two clip-engaging projections 110 A, 110 B, which project downwardly and are connected by means of a ramped surface 111 which inclines downwardly from the rear of the shoulder 1 to the front of the shoulder 1 , for deflecting the leg of a railway rail fastening clip.
  • the front face 12 of the shoulder 1 is provided with projections 120 for engaging with the sleeper mould so as to set the shoulder at the correct height in the mould before the concrete is introduced.
  • the shoulder 1 has a rear face 15 opposite to the front face 12 .
  • the rail clip 3 is formed from a steel rod bent so as to have, proceeding from one end A of the rod to the other end B of the rod, firstly a straight first portion 31 forming one leg of the clip, then a bent second portion 32 which bends through more than 180°, then a third portion 33 , then a fourth portion 34 which forms the toe portion of the clip and is bent through 180°, then a fifth portion 35 which mirrors the shape of the third portion 33 , then a sixth portion 36 which mirrors the shape of the second portion 32 and finally a seventh portion 37 which forms the other leg of the clip.
  • the clip when viewed as seen in FIG. 3A , the clip may be considered to be substantially M-shaped.
  • the free ends A, B, of the rod have a chamfer 37 a on the surface of the leg which is to be uppermost when the clip 3 is bearing on a rail for assisting in inserting the clip into the shoulder.
  • Adjacent to the ends A, B, on the uppermost surface of the clip 3 the clip 3 is formed with detents 38 for cooperating with the projections 110 A, 110 B formed on the walls 10 of the shoulder 1 to retain the clip 3 .
  • the detents 38 are formed so as to have two oppositely-inclined spaced-apart faces defining respective pre-assembly and insulator-change positions relative to the shoulder 1 .
  • the toe portion 34 of the clip 3 when in use normally carries a toe insulator 34 a for insulating the clip 3 from the rail.
  • the toe insulator 34 a also extends over parts of the third and fifth portions, 33 , 35 of the clip 3 .
  • those portions of the toe portion 34 and third and fifth portions 33 , 35 which come into contact with the toe insulator 34 a when it is located on the clip 3 may be left free of the coating which is generally applied to the remainder of the clip.
  • the longitudinal axes of all parts of the clip lie substantially in the same plane P, that is the clip is flat.
  • the above-described clip may be made from 14 mm diameter bar instead of 15 mm.
  • the clip is smaller in plan view, both shorter by about 10 mm and narrower by about 10 mm.
  • the clip may be rolled around smaller radius formers to make the arches of the clip, in particular at the toe of the clip, as a consequence of which, and the smaller diameter, the clip may be significantly lighter. It also operates at a slightly higher stress level.
  • the clip may be initially produced with some profile and then cold-set so that it returns to a flat shape (i.e. over-pressed when cold such that it yields and takes on some permanent deformation).
  • the railway rail fastening assembly of FIGS. 4A to 4F for fastening a railway rail 5 , comprises a shoulder 1 , a rail fastening clip 3 , a sealing plate 2 and a rail pad 4 embodying the first aspect of the present invention. It will be appreciated that, although not shown in FIGS. 4A to 4F , when in use the rail is fastened on both sides of the rail head by such an assembly and that the stem 1 B and tangs 1 C are embedded in the concrete sleeper 6 .
  • the sealing plate 2 is also embedded in the concrete sleeper 6 , such that the top face of sealing plate 2 is flush with the upper surface of the sleeper 6 .
  • the clip 3 may be driven into the shoulder 1 by introducing the chamfered free ends A, B of the clip legs 31 , 37 into the gaps between the top surfaces 25 a of the clip seat projections 25 on the sealing plate 2 and the first projection 110 A on the outer surface of the walls 10 of the shoulder 1 , and inserting the toe portion 34 of the clip 3 , bearing a toe insulator 34 a, into the space between the inner surfaces of the walls 10 of the shoulder 1 , such that the toe 34 of the clip 3 , through the toe insulator 34 a, bears on the ramp 140 of the shoulder 1 and the projections 110 A are located within the detents 38 in the clip legs 31 , 37 , with the projection 110 A contacting the rear face of the detent 38 .
  • This position is known as the “pre-assembly” or “parked” position, in which the clip does not bear on the rail 5 , but overlies the shelf 47 of the side post insulator portion 46 of pad 4 . Downwardly-facing parts of the legs 31 , 37 rest on the top surfaces 25 a of the clip seat projections 25 .
  • the clip 3 can be driven from the pre-assembly position (first operative position) into a second operative position in which the toe portion 34 of the clip 3 bears on the foot of the rail 5 , the second projections 110 B on the walls 10 engage the detents 38 of legs 31 , 37 of the clip 3 and the second and sixth portions 32 , 36 (heel portions) of the clip 3 bear on the top surfaces 25 a of the clip seat projections 25 .
  • the clip overlies the shelf 47 of the side post insulator portion 46 of the rail pad 4 .
  • the clip can be withdrawn from this position back into the pre-assembly position, if required in order to remove or work on the rail, or further back into the “insulator-change” position in which the front face of the detent 38 contacts the projection 110 A and the clip 3 does not overlie the shelf 47 of the sidepost insulator portion 46 of pad 4 .
  • the toe 34 of the clip 3 is driven upwards by the ramp 140 in the centre of the shoulder 1 , and the legs 31 , 37 are driven down, thereby splitting the clip open. This makes it possible to make the assembly a little lower than would otherwise be possible.
