Patent ID: 8915452

Claim:
A joint connector bar for connecting adjoining end portions of rails of different height in a track structure, the adjoining end portions of the rails each having oblique surfaces, the oblique surfaces of the adjoining end portions of the rails including: an upper arcuate oblique surface formed below a head portion of the rails extending arcuately inwardly towards a web portion of the rails, and a lower planar oblique surface formed sloping upwardly on a foot portion and extending inwardly towards the web portion of the rails, the leveling joint connector bar comprising: a joint body member to span the adjoining end portions of the rails to be joined and having a number of connector holes formed therein aligned with connector holes in the web portions of the adjoining end portions of the rails to be joined; the joint body member having an arcuate oblique upper surface formed with and extending along the length of the joint body, the arcuate oblique upper surface of the joint body member being machined to conform to and engage along its extent with the arcuate inwardly extending upper oblique surfaces beginning at a lower end of a side wall below the head portions along their inward extent towards the web portions of the adjoining end portions of the rails to be joined; the joint body member having an upwardly sloping planar oblique lower surface formed with and extending along the length of a first segment of the joint body member and being machined to conform to and engage with the upwardly sloping planar oblique surface formed on the base portion of a first of the two rails to be joined; the joint body member having an upwardly sloping planar oblique lower surface formed with and extending along the length of a second segment of the joint body member and being machined to conform to and engage with the upwardly sloping planar oblique surface formed on the base portion of a second of the two rails to be joined; the arcuate oblique upper surface of the joint body member and the upwardly sloping planar oblique lower surface of the first segment of the joint body member being spaced from each other along the first segment of the joint body member a distance corresponding to the height of the web portion of the first of the two rails to be joined; and the arcuate oblique upper surface of the joint body member and the upwardly sloping planar oblique lower surface of the second segment of the joint body member being spaced from each other along the second segment of the joint body member a distance corresponding to the height of the web portion of the second of the two rails to be joined.
