Abstract

A wooden railway sleeper 8 has four holes 9 in it, extending downwardly from its upper surface, each hole having in it a stem portion 1 of an anchorage member and material 12 which has set in the hole and holds the stem portion 1 in the hole. Each of the four anchorage members is of sheet metal and has an arch 3 beneath which a passageway is formed into which a leg 13 of a clip, for holding a rail 11 down on the sleeper, can be driven. One rail is between two anchorage members and located by them and another rail is between the other two anchorage members and located by them. Portions 14 of the clips bear on the rail flange and portions 15 of the clips bear on portions 5 of the anchorage members. The sleeper may be for a narrow-gauge railway and may have been made by cutting down a sleeper originally intended for a wider gauge railway. <IMAGE>

Description

SPECIFICATION A wooden railway sleeper and a railway railand-fastening assembly employing it According to a first aspect of the invention, there is provided a wooden railway sleeper having four holes in it extending downwardly from its upper surface, each hole having in it a stem portion of a respective anchorage member and a quantity of material which has set in the hole and holds the stem portion in it, each of the four anchorage members having a further portion which forms a passageway into which can be driven a leg of a clip for holding down a rail.

According to another aspect of the invention, there is provided a railway rail-and-fastening assembly including a wooden railway sleeper, anchorage members and materials according to the first aspect of the invention, a first rail having at its foot a flange between and located by two anchorage members, a second rail having at its foot a flange between and located by the other two anchorage members and four clips each having a first part in the form of a substantially straight leg which has been driven into a respective one of the passageways, a second part bearing downwardly on the flange of the rail and a third part bearing downwardly on a surface which, as seen from the rail, is beyond the pertaining passageway.

The clip may be substantially as shown in any of the following British Patent Specifications: 861,473,884,237,1,213,762 or 1,510,224.

The wooden sleeper may have been made by cutting parts off a larger wooden sleeper. For example, a sleeper for a narrow gauge railway may be made by cutting down an old sleeper made from a wider gauge railway.

Each anchorage member may itself incorporate the above-mentioned surface.

An example according to the invention is described below with reference to the accompanying drawings, in which: Figure 1 shows a side view of an anchorage member, Figures 2 and 3 show views of the anchorage member, taken as indicated by the arrows II and Ill, respectively in Figure 1, Figure 4 shows an end view of part of a railway rail-and-fastening assembly.

Figure 5 shows a side view of the same part, and Figure 6 shows a plan view of the same part.

Figures 1 to 3 show an anchorage member which has been made by pressing an elongate flat piece of sheet steel about 8 mm thick so that it comprises; proceeding from one end A to the other end B, (a) a stem portion 1 which is corrugated, (b) a vertical portion 2 (c) an arch 3 (d) a curved portion 4 (e) a horizontal portion 5 (f) a curved portion 6 (g) a vertical portion 7 the portions 2 to 7 all being about 75 mm wide (measured left to right in Figure 2) and the. portion 1 being about 20 mm. wide.

Figures 4 to 6 shows part of a wooden railway sleeper 8 about 1.22 metres long, 127 mm. wide and 127 mm. thick which has been made by cutting into four equal parts a sleeper, for a widergauge track, about 2.44 metres long, 254 mm.

wide and 127 mm. thick. Near one end of the sleeper there are two holes of circular crosssection drilled downwardly from the top of the sleeper, only one of these being shown in Figure 4, referenced 9. Into each of these holes is inserted a portion 1 of one of two anchoring members, the portions 2 of the two anchoring members being between the portions 7 and serving to locate the flange 10 at the foot of a rail 11 which is laid on the sleeper. Each hole is filled with epoxy resin 12 which sets and holds the portions 1 in the holes.

The ends B of the anchoring members rest on the top of the sleeper.

Two clips substantially as shown in British Patent Specification No. 1,213,762 have their substantially straight legs 1 3 driven, in opposite directions, substantially parallel to the length of the rail into passageways afforded by the arches 3, the legs 1 3 pressing upwardly. Flat portions 14 of the clips bear downwardly on the flange of the rail and further portions 1 5 bear downwardly on the portions 5 of the anchoring members.

The construction at the other end of the sleeper is exactly the same as that shown in Figures 4 to 6.

An important feature of the anchoring members is that there is only one leg (portion 1) extending into the sleeper.

1. A wooden railway sleeper having four holes in it extending downwardly from its upper surface, each hole having in it a stem portion of a respective anchorage member and a quantity of material which has set in the hole and holds the stem portion in it, each of the four anchorage members having a further portion which forms a passageway into which can be driven a leg of a clip for holding down a rail.

2. A railway sleeper and anchorage members secured to it according to claim 1 in which each of the four anchorage members has only one part of it, i.e. said stem portion, extending into the sleeper.

3. A railway sleeper and anchorage members secured to it according to claim 1 or 2, the sleeper having been made by cutting parts off a larger wooden railway sleeper.

4. A railway sleeper and anchorage members secured to it according to claim 3, suitable for a narrow gauge railway, the sleeper having been made by cutting down on old sleeper which was suitable for a wide gauge railway.

5. A railway sleeper and anchorage members secured to it according to claim 4, the sleeper having been made by cutting the old sleeper into
