Abstract

A mount for a railroad rail having an inner side turned toward another such rail and an outer side turned away from the other rail has a one-piece base supported on the ground under the one rail and formed with an upwardly open recess having inner and outer base flanks respectively generally under and parallel to the inner and outer sides, the outer base flank being formed as an inwardly overhanging ridge. An insert attached to the rail and received in the recess has respective inner and outer insert edges, the former of which is overhung by the ridge. An elastomeric body lies between the inner flank and inner edge and supports the insert in the base. Due to the overhang of the base edge, it is possible to make the base in one piece at least outward from a location underneath the rail. Thus there is no need to make the base from two parts split along a horizontal plane and requiring tedious assembly in the field.

Claims9

Dependent claims

A railroad rail assembly comprising:

a metal base plate having along one side thereof a flank inclined to the vertical and a horizontal portion integral with said flank;
a metal insert plate spaced above said horizontal portion and having along an edge thereof a flank inclined to the vertical and juxtaposed spacedly with said flank of said base plate, said flank of said base plate overhanging said insert plate and having an upper edge lying inwardly of the outline of said insert plate at said edge thereof;
a rail resting on said insert plate and supported thereby in spaced relation from said flanks;
a least one body of elastomeric material received between said insert and said bottom portion and between said flanks with at least part of said body of elastomeric material overhanging said insert plate outwardly of said rail for supporting said insert plate on said base plate;
and
said flank of said base plate partically enclosing said body of elastomeric material and said edge of said insert plate.
