Abstract
An inverted channel shaped sleeper has a top surface (12) for supporting a laterally extending flanged rail. The top surface has an aperture (15a) adjacent the rail and an elongate slot (16a) spaced from the opposite side of the rail and extending longitudinally of the sleeper. A spring clip has an elongate portion (22) extending through the sleeper beneath the rail, a cranked end portion (23) which extends through the aperture to abut one side of the rail and a hook-like portion (21) which extends through the slot and resiliently clamps down a flange of the rail. <IMAGE>
Description
SPECIFICATION
Fastener for securing a rail to
The present invention provides a fastener for securing a rail to a sleeper.
The invention is concerned with an inverted channel-shaped type sleeper. Sleepers of this type are metal pressings and have a flat top surface for supporting a rail, or a pair of rails.
It is known to form the top surface with projections to locate a rail relative to the sleeper, with the rail lying transversely across the top surface. It is also usual for adaptation of the top surface to be required for the securance of fasteners by means of which the located rail is held in position. A sleeper and fastener combination of this type is disclosed in GB-A-2063972.
The present invention avoids the necessity for forming locating projections on the sleeper and permits a sleeper to be made of simple channel form.
In accordance with this invention, there is provided a fastener for securing a rail to a sleeper of inverted channel form having a flat top for supporting a rail and having apertures in the top at opposite sides of a rail-supporting portion of the sleeper, the fastener having an elongate intermediate portion for extending beneath said portion between the apertures, a relatively cranked first end portion for extending through a first said aperture to serve as a location stop for the rail, and a second end portion for extending through the second said aperture and engaging the rail to clamp it to the rail-supporting portion of the sleeper.
The invention also resides in a sleeper of inverted channel form having a flat top for supporting a rail and having first and second apertures, the apertures being located at opposite sides of a rail-supporting portion of the top of the sleeper, and a fastener which has an elongate and intermediate portion and cranked end portions, whereby the fastener can be positioned extending beneath the rail supporting portion with its first end portion extending through the first aperture, to serve as a locating projection for the rail and the opposite second end portion extending through the second aperture to clamp the rail to the rail-supporting portion.
Preferably two pairs of said first and second apertures are provided spaced laterally of the sleeper, each pair receiving a respective said fastener, the first aperture of each pair being aligned with the second aperture of the other pair, whereby the fasteners can be relatively reversed, so that the first end portion of one fastener is located at one side of the railsupporting portion and the first end portion of the other fastener is located at the opposite side of the rail-supporting portion, for locating a rail between the two first end portions.
Preferably, each first aperture is located immediately adjacent the rail-supporting portion, whereas each second aperture is spaced from the rail-supporting portion and extends longitudinally of the sleeper.
Instead of two spaced fasteners, one fastener may be used with two studs secured to the sleeper to replace the other fastener, one at each side of the rail. One stud may be headed for engaging with a flange of the rail.
Reference is now made to the accompanying drawings, wherein:
Figure 1 is a sectional view of part of a sleeper, fastener and rail combination;
Figure 2 is a plan view of the combination shown in Fig. 1; and
Figure 3 is a perspective view of part of the sleeper, with portions broken away.
The sleeper 11 shown is of inverted channel form and is made from pressed steel. The ends of the sleeper are not shown, but these will advantageously be tapered to form closed ends to the channel. Longitudinal flanges may be provided to spread the load on the sleeper, in use. The sleeper has a flat top 1 2 having a rail-supporting portion 1 3. A rail 14 extends transversely across the sleeper and lies on the rail-supporting portion 1 3. A further such portion will be formed for supporting a second rail of a pair of rails to form a track.
The sleeper has two pairs of apertures, formed in the top 12, the pairs being spaced laterally of the sleeper. Each pair comprises first and second apertures 15a, 15b and 1 6a, 1 6b at opposite sides of the rail (and hence of the rail-supporting portion 13). The first apertures 15a, 15b are located immediately adjacent the rail 1 4 at opposite sides of the rail.
The second apertures 16a, 1 6b are spaced from the rail, at opposite sides thereof, and extend longitudinally of the sleeper.
A pair of fasteners 20, 21 are provided in the form of spring clips. Each clip is made from a length of spring material to provide an intermediate elongate portion 22, a first end portion 23 and a second end portion 24. The intermediate portion has a part 22a adjacent to the first end portion 23 which is cranked substantially perpendicularly to the part 22a.
The intermediate portion 22 has a further part 22b which is a continuation of the part 22a, but extends at a slight acute angle to the part 22a. The second end portion 24 is of hooklike formation and curves back through over 1 80' from the part 22b of the intermediate portion 22.
Each first end portion 23 is received in a corresponding first aperture 15a, 15b and each second end portion 24 is received in a corresponding second aperture 1 6a, 1 6b, with the intermediate portions 22 extending between the apertures of each pair. Each clip is inserted through the corresponding second aperture and slid into position until the first end portion 23 snaps into its aperture. The second end portion of each clip engages with a flange 1 4a, 1 4b of the rail. The part 22b of the intermediate portion adjacent the second end portion 24 extends downwardly away from the top 12 of the sleeper and facilitates engagement of the clip.
The first end portions 23, being located at opposite sides of the rail, serve to locate the rail relative to the sleeper.
The second end portions clamp the rail to the rail-supporting portion of the sleeper and, since they act in opposing directions due to the sloping top surfaces of the flanges 1 4a, 1 4b, this stabilises the rail relative to the sleeper.
