Abstract
A leveling joint between connected ends of two rails of different height is provided with a connector/juncture bar member which is configured to fit with and engage corresponding surfaces formed on the rails when the rails are connected together. The leveling joint so formed is one with increased strength, with ease and accuracy of alignment during assembly. The leveling joint is formed of several structural members, yet functions as and affords the strength and stability of a solid, unitary assembly.

A leveling joint connector bar for longitudinally connecting adjoining end portions of rails end-to-end lengthwise to each other in a track structure, the end portions of the rails to be longitudinally connected being of different height, and further having connector holes in their web portions at different heights, respectively, from each other, the end portions of the rails of different heights having flat vertical surfaces of different heights on their respective end portions, and different vertical spacing between respective head and base portions thereof, the leveling joint connector comprising:
- an elongate joint body to longitudinally span the adjoining end portions of the rails to be joined and having a number of connector holes formed therein at different heights for alignment with the connector holes in the web portions of the adjoining end portions of the rails of different height to be joined;
- the elongate joint body having a height along its longitudinal extent conforming to the different vertical spacing between the respective head and rail portions of the adjoining end portions of the rails to be joined;
- an engaging shoulder member formed with and extending along the length of the joint body, the engaging shoulder member having a number of connector holes formed at different heights therein aligned with the connector holes at different heights in the joint body and the connector holes in the web portions of the adjoining end portions of the rails of different height to be joined;
- the engaging shoulder member having an inwardly extending portion having a flat vertical contact surface at different heights thereon for engaging the flat vertical surfaces of different heights on the web portions of the adjoining end portions of the rails of different height to be joined;
- the joint body being located outwardly of the engaging shoulder member and adapted to be fitted between head and base portions of the adjoining end portions of the rails of different height to be joined;
- the joint body having a downwardly extending contact rib member formed along its length;
- the downwardly extending contact rib member having horizontal contact surfaces formed thereon for engaging with corresponding horizontal flat surfaces formed on a sloped surface of the respective base portions of the adjoining end portions of the rails to be joined;
- the joint body having an upper contact rib member formed on an upper surface thereof extending along its length;
- the upper contact rib having a horizontal upper contact surface thereon for engaging corresponding horizontal flat surfaces below the respective head portions of the adjoining end portions of the rails to be joined;
- the joint body having a different height between the downwardly extending contact rib member and the upper contact rib along its length to correspond to the vertical spacing between respective head and rail portions of the rails of different height;
- and
- the spacing of the vertical surface of the engaging shoulder member from the contact surfaces on the upper and lower contact rib members corresponding to the spacing of the flat vertical surfaces on the web portions from the horizontal flat surfaces on the rail base portion and the horizontal flat surfaces below the head portion of the rails to be joined.

A rail track structure formed at adjoining longitudinal end portions of rails joined end-to-end lengthwise to each other, the rail end portions having differing height characteristics, comprising:
- a first track segment and a second track segment, each having a web portion, a base portion and a head portion, the end portions of the first and second track segments being of different heights and having flat vertical surfaces of different heights on their respective end portions, and different vertical spacing between respective head and base portions thereof;
- the web portions of the first and second track segments having a number of connector holes formed therein at different heights, respectively, from each other for the passage of connectors at their end portions;
- the head portions of the first and second track segments having horizontal flat surfaces formed on lower portions thereof;
- the base portion of the first track segment having horizontal flat surfaces formed on upper portions thereof;
- an elongate connector bar to longitudinally span the adjoining end portions of the first and second track segments to be joined end-to-end lengthwise and having a number of connector holes formed therein at different heights for alignment with the connector holes in the web portions of the adjoining end portions of the first and second track segments of different height to be joined;
- the elongate connector bar having a height along its longitudinal extent conforming to the different vertical spacing between the respective head and rail portions of the adjoining end portions of the first and second track segments to be joined;
- an engaging shoulder member extending along the length of the connector bar, the engaging shoulder member having a number of connector holes formed at different heights therein aligned with the connector holes at different heights in the connector bar and the connector holes in the web portions of the adjoining end portions of the first and second track segments of different height to be joined;
- the engaging shoulder member having an inwardly extending portion having a flat vertical contact surface at different heights thereon for engaging the flat vertical surfaces of different heights on the web portions of the adjoining end portions of the first and second track segments of different height to be joined;
- the connector bar being located outwardly at the engaging shoulder and adapted to be fitted between head and base portions of the adjoining end portions of the first and second track segments of different height to be joined;
- the connector bar having a downwardly extending contact rib member formed along its length;
- and
- the downwardly extending contact rib member having horizontal contact surfaces formed thereon for engaging with corresponding horizontal flat surfaces formed on sloped surfaces of base portions of the respective adjoining end portions of the first and second track segments to be joined;
- the connector bar having an upper contact rib member formed on an upper surface thereof extending along its length;
- the upper contact rib member having a horizontal upper contact surface thereon for engaging corresponding horizontal flat surfaces below the respective head portions of the adjoining end portions of the first and second track segments to be joined;
- the connector bar having a height between the downwardly extending contact rib member and the upper contact rib along its length to correspond to the vertical spacing between respective head and rail portions of the first and second track segments of different height;
- and
- the spacing of the vertical surface of the engaging shoulder member from the contact surfaces on the upper and lower contact rib members corresponding to the spacing of the flat vertical surfaces on the web portions from the horizontal flat surfaces on the rail base portion and the horizontal flat surfaces below the head portion of the first and second track segments to be joined.
