Abstract

A fastener has a base plate on which a stock-rail foot sits, a slide chair fixed to the base plate and having an overhang overreaching an edge of the flange, an abutment bump projecting downward from the overhang, a passage opening adjacent and above the flange underneath the overhang, and a flat upper surface. A retaining element engaged in the passage and bearing downward on the flange edge is engageable with the bump.

Claims (7)

1. In combination with a stock rail having a flanged foot, a fastener comprising:
a base plate on which the stock-rail foot sits;
a slide chair fixed to the base plate and having an overhang overreaching an edge of the flange, an abutment bump projecting downward from the overhang, a passage opening adjacent and above the flange underneath the overhang, and a flat upper surface; and a retaining element engaged in the passage, bearing downward on the flange edge, and engageable with the bump.
2. The stock-rail fastener defined in claim 1 wherein the bump is above the retaining element.
3. The stock-rail fastener defined in claim 1 wherein the chair is formed with two abutment bumps.
4. The stock-rail fastener defined in claim 3 wherein the bumps horizontally flank the retaining element offset from the passage.
5. The stock-rail fastener defined in claim 3 wherein the bumps are directly above the retaining element.
6. The stock-rail fastener defined in claim 5 wherein the retaining element is a clip having a pair of legs each vertically below a respective one of the bumps.
7. The stock-rail fastener defined in claim 1 wherein the slide chair forms beneath the overhang a recess having a surface of a large radius of curvature turned toward the stock rail.
