Rail joint bars and rail joint assemblies
View Patent ↗A rail joint assembly is provided for joining abutting railroad rails with an electrically-insulated joint. The rail joint assembly comprises abutting railroad rails compressing an insulating gasket therebetween and rail joint bars secured through a plurality of holes by fasteners to the adjacent railroad rails. The rail joint bars comprise a body and an insulating spacer comprising a porous mesh screen and washer. A layer of epoxy is sandwiched between a rail joint bar and railroad rail and comprises a rigid epoxy on lateral portions of a first side of a rail joint bar and a flexible epoxy placed on a central portion of the first side of a rail joint bar. Rail joint bars are rectangular shaped and may have a cutout.
1. An electrically-insulating spacer arrangement for positioning between two adjacent rail ends, comprising a body and a first gasket, the body having a T-shaped profile corresponding to an end face profile of the rail ends and the first gasket having a profile which is different from the T-shaped profile of the body,
wherein the body comprises an electrically-insulating material that is substantially incompressible and has at least a first face and defines a single first gasket-receiving groove on the first face, and
wherein the first gasket is received by the single first gasket-receiving groove on the first face, extends beyond the first face of the body and is a compressible electrically-insulating gasket coacting with the body, and wherein the first gasket covers only a portion of the first face of the body before compression of the first gasket occurs.
2. An electrically-insulating spacer arrangement as claimed in claim 1 , further comprising a second gasket having a profile which is different from the T-shaped profile of the body, and wherein the body has a second face opposing the first face and defines a single second gasket-receiving groove on the second face, and
wherein the second gasket is received by the single second gasket-receiving groove on the second face, extends beyond the second face of the body and is a compressible electrically-insulating gasket coacting with the body, and wherein the second gasket covers only a portion of the second face of the body before compression of the second gasket occurs.
3. An electrically-insulating spacer arrangement as claimed in claim 2 , wherein the single first gasket-receiving groove has the same configuration as the first gasket and wherein the single second gasket-receiving groove has the same configuration as the second gasket.
4. An electrically-insulating spacer arrangement as claimed in claim 2 , wherein the body includes a web and a head positioned above the web, wherein the single first and second gasket-receiving grooves and the first and second gaskets are provided in the head and are arcuate shaped.
5. An electrically-insulating spacer arrangement for positioning between two adjacent rail ends comprising a body, wherein the body comprises an electrically-insulating material that is substantially incompressible, and a compressible electrically-insulating gasket coacting with the body, wherein the compressible gasket covers only a portion of the electrically-insulating material before compression of the compressible gasket occurs, and
wherein the body has a T-shaped profile corresponding to an end face profile of the rail ends and the gasket has a profile which is different from the T-shaped profile of the body.
6. An electrically-insulating spacer arrangement as claimed in claim 5 , wherein the body has opposed faces and a second gasket is provided, a respective one of the gaskets is received by each face.
7. An electrically-insulating spacer arrangement as claimed in claim 6 , wherein the body defines a gasket-receiving groove on each face, the gaskets received by a respective groove and the gaskets extending beyond the respective faces.
8. An electrically-insulating spacer arrangement as claimed in claim 6 , wherein the body includes a head positioned above a web, wherein the gaskets are provided in the head and are arcuate shaped.
9. An electrically-insulating spacer arrangement as claimed in claim 7 , wherein each respective groove has a configuration corresponding to its respective gasket.
