20090108086 | Notched Tie Plate Insulator - A notched tie plate insulator adapted to be received within a recessed area of a tie plate of a railroad rail system. The insulator includes a bottom plate having a first side and a second side and a pair of side plates attached to the bottom plate. Each side of the bottom plate defines a notch therein. The side plate includes a longitudinal extending body having an upper surface and a lower surface and defining a recess on the upper surface and a protrusion on the lower surface, wherein the protrusion of each of the side plates is received within the notches of the bottom plate. | 04-30-2009 |
20090121037 | Rail Joint Bars And Rail Joint Assemblies - 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. | 05-14-2009 |
20090302125 | Center Supported Bond Joint - A center support sleeve for a bonded rail joint bar that includes a body having a head portion, a web portion, and a base portion. The head portion depends from the web portion, which depends from the base portion. The head portion and the base portion are bent in the same direction thereby defining a recess area therebetween. The web portion of the body also defines a plurality of holes. | 12-10-2009 |
20100270386 | Bolt on Continuous Rail Joint - A rail joint includes a top section and a bottom section. The top section has an upper end and a lower end. The bottom section has an upper portion, an intermediate portion, and a lower portion. The intermediate portion is positioned between the upper portion and the lower portion. The lower end of the top section is secured to the bottom section via at least one of a fastener, a welded joint, and a tongue and groove joint. | 10-28-2010 |
20110147474 | Method and Arrangement to Insulate Rail Ends - A rail joint arrangement comprises two rails. The rails have adjacent rail ends separated and thereby forming a gap. The rails have a top end containing a rail head and a bottom end. The gap is defined between the top end and the bottom end of the rails, and the width of the gap is non-uniform throughout its entire length. In addition, the rail joint arrangement comprises at least one electric insulator positioned within the gap. The rail joint arrangement is fastened together by a rail joint bar attaching the two rails together. | 06-23-2011 |
20120111958 | Lap Joint - A rail joint bar for use in an insulated lap joint assembly includes a longitudinal extending body defining a plurality of holes therein for receiving fasteners. The body has a first end and a second end positioned at opposite ends of the body relative to a longitudinal direction of the body. The body is bent forming a first portion adjacent to the first end, a second portion adjacent to the second end and spaced from the first portion in the longitudinal direction, and an intermediate portion defined therebetween and positioned between the first and second ends. The first portion and the second portion are substantially parallel to each other and, and the intermediate portion of the body is configured to accommodate an increase in thickness of a web section at a point where two railroad rails are joined. | 05-10-2012 |
20120223151 | Center Supported Bond Joint - A center support sleeve for a bonded rail joint bar that includes a body having a head portion, a web portion, and a base portion. The head portion depends from the web portion, which depends from the base portion. The head portion and the base portion are bent in the same direction thereby defining a recess area therebetween. The web portion of the body also defines a plurality of holes. | 09-06-2012 |
20140076980 | Single Bend Rail - A railroad rail includes a body defining a first section and a tapered second section with the body defining a head section, a web section depending from the head section, and a base section depending from the web section. The head section, the web section, and the base section define an end surface configured to mate with a corresponding end surface of a complementary railroad rail when joined together. The railroad rail is formed from a single bent railroad rail having only a single bend defined by the head section, web section, and base section of the body of the railroad rail. | 03-20-2014 |
