Abstract

Claims (26)

1. A railroad tie rail seat assembly for supporting a rail which includes:

a) a concrete rail tie rail seat and a rail lying across said rail seat;

b) a pair of rail clip support shoulders cast in place in said rail seat each said shoulder having a rail face between its external sides, and a rear side remote from said rail face, and a clip gateway through said rail face;

c) a rail pad on said rail seat between said support shoulders and beneath said rail;

d) said rail having a rail base with a leading edge adjacent the rail face of each support shoulder and a surface of said rail base being inclined upwardly in a direction away from said support shoulder;

e) a pair of shoulder insulators each shaped to lie against the rail face of the rail shoulder;

f) a pair of rail clips each having a base section adapted to seat within the rail clip support shoulder and a toe section adapted to seat on the rail base, the toe section comprising a pair of bifurcated arms extending from said base section and being bent in a curve so that the toes lie adjacent but beyond the clip base;

g) a pair of toe insulators each adapted to fit about the toe section of the rail clip to insulate the clip from the rail base and each consists of a body portion having a forward wall, a base section and a rear wall and a rear end;

h) each said toe insulator incorporating a recess for each arm of the toe section of the rail clip with sufficient width to enable the bifurcated arms of the rail clip to compress together as they pass through the gateway of the shoulder;

i) each said toe recess being defined by said forward wall and said rear wall which are abutted by the toe section of the rail clip so that the toe insulator moves with the rail clip;

j) a rail side of said forward wall of each said toe insulator is radiussed to enable the insulator to ride over said leading edge of said rail base and up an inclined surface of the rail base; and

k) the arrangement of a rail tie, support shoulders, shoulder insulators, rail clip and toe insulators being such that the rail clip has a first stable position in the shoulder where the toe insulators do not project beyond the rail face of said shoulder insulator so that a rail can be laid between rail shoulders and respective shoulder insulators and a loaded position where the toe insulator and the toe section of the rail clip lie on the rail base.

2. A railroad tie rail seat assembly for supporting a rail which includes:

a) a concrete rail tie rail seat and a rail lying across said rail seat;

b) a pair of rail clip support shoulders cast in place in said rail seat each said shoulder having a rail face between its external sides, and a rear side remote from said rail face, and a clip gateway through said rail face;

c) a rail pad on said rail seat between said support shoulders and beneath said rail;

d) said rail having a rail base with a leading edge adjacent the rail face of each support shoulder and a surface of said rail base being inclined upwardly in a direction away from said support shoulder;

e) a pair of shoulder insulators each shaped to lie against the rail face of the rail shoulder;

f) a pair of rail clips each having a base section adapted to seat within the rail clip support shoulder and a toe section adapted to seat on the rail base, the toe section comprising a pair of bifurcated arms extending from said base section and being bent in a curve so that the toes lie adjacent but beyond the clip base;

g) a pair of toe insulators each adapted to fit about the toe section of the rail clip to insulate the clip from the rail base and each includes of a body portion having a forward wall, a base section and a rear wall and a rear end;

h) each said toe insulator incorporating a recess for each arm of the toe section of the rail clip with sufficient width to enable the bifurcated arms of the rail clip to compress together as they pass through the gateway of the shoulder;

i) each said toe recess being defined by said forward wall and said rear wall which are abutted by the toe section of the rail clip so that the toe insulator moves with the rail clip;

j) a rail side of said forward wall of each said toe insulator is radiussed to enable the insulator to ride over said leading edge of said rail base and up an inclined surface of the rail base; and

k) the arrangement of a rail tie, support shoulders, shoulder insulators, rail clip and toe insulators being such that the rail clip has a first stable position in the shoulder where the toe insulators do not project beyond the rail face of said shoulder insulator so that a rail can be laid between rail shoulders and respective shoulder insulators and a loaded position where the toe insulator and the toe section of the rail clip lie on the rail base.

3. A railroad tie rail seat assembly as claimed in claim 2 in which the rear end of the toe insulator is adjacent or touching the base of the rail clip so that the rail clip base is able to assist in pushing the toe insulator onto the rail base.

4. A railroad tie rail set assembly as claimed in claim 2 in which the rear end of the toe insulator remains in the gateway of either or both the support shoulder and the shoulder insulator when the clip is in the loaded position with the toes of the clip over the rail base.
