Rail fastening apparatus
An elongated rail fastener apparatus for use near an obstacle such as a guard rail, or other location where space is restricted. The fastener preferably extends past the obstacle and is provided with a shoulder having at least one elevated notch, positioned to allow installation of the clip with a vertical and lateral movement, and without the application of a large force perpendicular to the rail. A U-shaped embodiment of the fastener is also described.
1. A rail fastening apparatus to restrain a rail flange on a tie plate, comprising:
a first retainer mounted on the tie plate near the rail flange;
a first shoulder mounted on the tie plate at a distance from the first retainer, the first shoulder comprising a first notch in a side surface of the first shoulder, above an upper surface of the tie plate; and
an elongated resilient fastener having a heel end and a toe end, and a body length between the heel end and the toe end that is greater than the distance;
wherein the elongated resilient fastener fits through the retainer and the heel end fits in the first notch on the first shoulder such that the toe end of the elongated resilient fastener restrains the rail flange; and
wherein the heel end is inserted into the first notch by lifting the heel end and moving the heal end laterally to the first notch.
2. The rail fastening apparatus of claim 1 wherein the shoulder further comprises:
a second notch between the first notch and the tie plate;
wherein the heel end is lifted and moved laterally to the second notch before being further lifted and moved laterally to the first notch.
3. The rail fastening apparatus of claim 1 , further comprising:
a second retainer mounted on the tie plate, spaced from the first retainer;
a second shoulder mounted on the tie plate spaced from the second retainer;
wherein the elongated resilient fastener has a U-shape, comprising first and second elongated leg members separated by a base member; and
the first elongated leg member fits through the first retainer and in the notch in the first shoulder and the second elongated leg member fits through the second retainer and in a notch on the second shoulder.
