A rail joint made from a metallic profiled bar that is rolled or forged and is used for connecting adjacent railroad rails to each other. The rail joint is configured to provide increased wheel flange clearance while maintaining the integrity of joining two rails together.
Claims36
A rail joint comprising:
- a body having a length defined between a first end and a second end and defining a base section having a base front side and base back side, a web section having a web front side and a web back side, and a head section having a head front side and a head back side, said base section depends from said web section, and said web section depends from said head section,
- wherein a distance between said head front side and said head back side of said head section is greater than or equal to a distance between said base front side and said base back side of said base section, and wherein the Moment of Inertia (I) of the rail joint is in a range of 14 to 15 in4 and the weight of the rail joint is in a range of 1.5 to 1.65 pounds per inch of length of said rail joint.
A rail joint assembly comprising:
- a pair of abutting railroad rails having a first side and a second side, each of said railroad rails having a body and defining a head, a web and a base, the head having a top surface connected to the base via the web, the web defines a plurality of slots for receiving fasteners;
- and
- a pair of rail joints, wherein a first rail joint is attached to said first side of said pair of rail sections and a second rail joint is attached to said second side of said pair of rail sections, each rail joint comprising a body having a length defined between a first end and a second end and defining a base section having a base front side and base back side, a web section having a web front side and a web back side, and a head section having a head front side and a head back side, said base section depends from said web section, and said web section depends from said head section, said web section of said body defining a plurality of holes, said head section having an upper surface defines an abutting portion, an intermediate portion and a lug portion,
- wherein a distance between said head front side and said head back side of said head section is greater than or equal to a distance between said base front side and said base back side of said base section, and wherein the Moment of Inertia (I) of the rail joint is in a range of 14 to 15 in4 and the weight of the rail joint is in a range of 1.5 to 1.65 pounds per inch of length of said rail joint.
