Abstract
The adjustable crossover includes first and second cross-members, each having a central disc with two opposed arms extending radially therefrom. Each disc has a series of radial teeth on one side thereof, with the radial teeth of the two discs engaging one another to lock the arms of the two discs at an angle to one another when the two discs are locked together. The distal ends of the arms include electric line connectors to facilitate attachment of electrical power lines or cables.
Claims18
An adjustable crossover for electric trolley lines, comprising:
- a first cross-member having a central disc and first and second mutually opposed elongate arms extending from the central disc, each of the arms of the first cross-member has an elongate shoe guide disposed therealong, each shoe guide having a substantially V-shaped cross-section, the central disc having a fastener passage defined centrally therethrough and opposing first and second surfaces, the first surface of the disc having a plurality of radially disposed teeth thereon;
- a second cross-member having a central disc and first and second mutually opposed elongate arms extending from the central disc, each of the arms of the second cross-member has an elongate shoe guide disposed therealong, each shoe guide having a substantially V-shaped cross-section, the central disc having a fastener passage defined centrally therethrough and opposing first and second surfaces, the second surface of the disc having a plurality of radially disposed teeth thereon, the teeth of the second surface of the disc of the second cross-member engaging the teeth of the first surface of the disc of the first cross-member when the first and second cross-members are secured together;
- an externally threaded fastener disposed through the fastener passages of the first and second cross-members, the externally threaded fastener has a head, the head having a substantially conical cross-section substantially congruent with the cross-section of each shoe guide of each of the arms, the head being substantially axially aligned with the shoe guide of each of the arms when the two cross-members are locked together;
- and
- an internally threaded fastener secured to the externally threaded fastener, the internally and externally threaded fasteners locking the first and second cross-members.
