ABSTRACT:
A duplex electrical collector for a rail electrification system comprises a pair of slim elongate back-to-back metal conductor shoes which are supported respectively intermediate their ends by short sturdy offset metal plates that project laterally of the shoes. The metal plates can be cast integral with the shoes, or else attached to the shoes by ribs that are crimped into grooves of the shoes. The metal plates have bores to accommodate a pivot pin that carries a torsion spring, thereby to impart a bias that tends to spread apart the shoes. The ends of a copper lead wire are secured to the plates, and a terminal strip is carried at the center of the lead wire. This assemblage is encased in an insulating two-part housing that mounts it, and is held captive by interlocking shoulders on the plates and housing parts. The center portion of the lead wire and the terminal attached thereto are brought out through a collar of the housing.
