ABSTRACT:
An anchoring device for use in anchoring a railway rail-fastening clip to a foundation for a railway rail has a head part, which anchors the clip and is to lie above the foundation, and a tail part which is to lie in the foundation and is in the form of a single vertical rod. At least one vane, to resist turning of the device about its vertical axis, has its upper extremity joined to the bottom of the head part and has one of its sides joined to the upper portion of the tail part, the vane having a vertical length and a horizontal width greater than its horizontal thickness. At least one projection, below the vane or vanes, projects laterally from the tail part and has a horizontal or nearly horizontal top, the projection or projections serving to resist vertical forces tending to pull the anchoring device vertically upwardly out of the foundation.
A concrete rail tie may have the tail parts of four of such anchoring devices embedded in it and a railway rail-and-fastening assembly may comprise a concrete foundation, a rail lying on it between the head parts of two such anchoring devices and two clips anchored by the anchoring devices and pressing downwardly on opposite sides of a flange at the bottom of the rail.
