ABSTRACT OF THE DISCLOSURE
An anchor for securing a rail clip to a concrete sleeper has two nibs which extend from a clip receiving shoulder on either side of a leg which is embedded in the sleeper. A lug may extend from the shoulder i the opposite direction between two further legs.

One sucb mean~ oompri~e~ an anchor whio~ i~ embedded ln ~he sleeper ~uring the concrete ca~t~ng opera-tion and which incorporates an arohea ~houlder or mould formed in a ~olld ~houlder to recelve a cllp whloh engage~
and holds the rail. Both pre~ed steel and ca~t i leabl~ iron con~truotion3 have been employed heretofore. However, the pressed steel fo~m~ have not been entirely ~atisfaotory ~ince they do not provida a~ positive a location and do not ~it mould~ intended for use with ca~t anohor~

the said other two l~gs 5 a lug 2 also extends away from the shoulder in the opposite direction to the nibs.
When a sleeper is cast the legs 5 fix the shoulder firmly in the cast concrete of the sleeper, and the single leg 3 is bent down away from the nibs thereby enabling the `
shoulder to conform with the shape of the pocket in the mould for casting the sleeper which is required to locate the cast metal shoulder that is more frequently used. The recess formed by this separation of the single leg of the shoulder 10 from the nibs 1 formed to provide a flat resting platform for ~`
the rail clip also provide a very useful restraint to prevent '~the clip vibrating out of position when it has been driven to the correct tension as once the clip is driven into this recess it has to be deformed before ;t can be retracted.

Claims

The embodiments of the invention in which an exclu-sive property or privilege is claimed are defined as follows:

1. A rail clip anchor comprising an arcuate shoulder to receive on its under side a clip which engages a rail, a single leg extending downwardly from one side of the shoulder for embedment in a concrete sleeper, a pair of further legs parallel with each other and spaced apart extending downwardly from the opposite side of the shoulder to the first leg and for embedment in a concrete sleeper, two spaced apart parallel nibs providing abutment surfaces for a clip received by the shoulder and extending outwardly from the shoulder and lying one on either side of the first leg, and a lug extending outwardly from the shoulder in a direction opposite to the nibs and between the pair of further legs and providing means for locating the anchor in a mould for casting a concrete sleeper thereabound.
