Abstract: In a system comprising at least two conductor rails, in particular composite sections each featuring a rail-shaped load-bearing section and at least one strip-shaped section of another metal of greater wear resistance joined to the matrix of the load-bearing section, the ends of pairs of neighbouring rails are connected electrically by at least one conductor of variable length. The ends of the conductor rails are bent out of the central axis (M) of the conductor rail and led parallel to and a distance (n) displaced from that axis, such that the strip-shaped section of one conductor rail end is approximately aligned with the strip-shaped section of the other conductor rail away from the rail end; the conductor rail ends are joined in such a manner that they can move with respect to each other along the axial direction.

Abstract: A conductor rail and method for its production. The rail is constituted as a bimetallic, non-integral, unitary laminate assemblage of two formed, nesting dissimilar metal strips, for sliding engagement by an electrical collector shoe. The assemblage has a grooved track portion for receiving the shoe, and a suspension portion adapted to be clamped by suspender fittings. One of the metal strips is fully exterior to the other strip and is preferably constituted of steel, whereas the other metal strip is preferably copper, characterized by relatively higher electrical conductivity. The arrangement is such that the nested strips are in intimate, large-surface contact with each other. The rail thus enjoys the advantage of high strength and abrasion resistance, and improved electrical performance. The rail can be utilized in new equipment, or as a replacement for worn or damaged rail sections, essentially without modification of existing hanger or insulating hardware, or existing jacketing insulations.

Abstract: In accordance with the present invention, a power conductor rail structure is provided using a multi-metallic construction. The composite rail of the invention includes an asymmetrical steel portion having a top flange thickness greater than that of the bottom flange in a generally I-shaped configuration with spaced apertures along the length of the web. Aluminum cladding is cast onto both sides of the web with a cold rolled high conductivity layer, such as copper disposed between the aluminum and steel on either side of the web and having holes corresponding in size and shape to the apertures of the web. The aluminum cladding extends through the web apertures producing a multi-metallic sandwich construction. The high conductivity layers provide a mechanical bond between the steel and aluminum and reduces transfer resistance and increasing overall conductivity.

Abstract: A composite continuous surface rail is constructed by combining a load-bearing support rail divided into segments to allow for thermal expansion with a continuous surface rail that slideably engages the support rail and spans any number of support rail segments. The continuous top or surface rail includes a running rail and an expansion rail. The expansion rail is provided to absorb thermal expansion of the running rail while continuing to provide a continuous composite rail surface. The surface rail and/or support rail may be electrified. An electrified running rail and expansion rail will provide an electrified composite rail with electrical continuity.

On the second joining surface is integrally formed a protrusion having an outer configuration substantially corresponding to the inner shape of the recess. The first and second materials are firmly mechanically joined to each other by, for example, a casting method, a rolling method, a pressing method, or a method utilizing plastic flow of the second material.

The cap is pressed against the top of the conductor bar during assembly and is permanently clamped to the bar by integral ears deformed over and down onto doubled over edges the side legs of the contact cap, holding the outer legs of the contact cap in tension, holding the cap against the top of the conductor bar.

Abstract: A process for producing an electrical supply rail comprising the following steps: (a) producing a mounting body and a wearing plate between rebates of the mounting body and edges of the wearing plate, interposing a sheet of electrically conductive material between the mounting body and the wearing plate; (b) mutually superposing faces of the mounting body and the wearing plate transversely with interposition of the sheet of electrically conductive material having a fusion temperature below those of the mounting body and of the wearing plate; (c) causing the fusion of the sheet by heating and exerting a stress on the mounting body and on the wearing plate; and (d) cooling the solidification of the continuous longitudinal film.

Abstract: A composite minimum-joint electrified rail is constructed by combining a non-conductive support rail divided into easily installed segments with a continuous conductive rail that mounts on the support rail and spans any number of support rail segments.

In addition spring clips are shown for attaching the support rail to railroad ties or roadbed, and fish plates are shown for attaching abutted support rails.

A long single sheet of stainless steel is bent to cover the protruding middle parts of the aligned rail bodies to form the continuous unified structural body and the ends of the two bent sides thereof are fixed in a gripping manner by bending the pair of protruding clamping strips inwardly to clamp the bent sides against the base part.

Abstract: A rail construction for rail-type electrification systems, comprising a metal, conducting carrier rail member of relatively high expansion coefficient, having a cross-sectional configuration somewhat like a pair of channel shapes disposed back-to-back. One channel shape is used for suspension or mounting, as well as rigidity. The other channel shape contains a metal insert in the form of a flat contact member of relatively low expansion coefficient which is secured in place by being pinched between opposed wall areas of flanges of the rail member, in consequence of the flanges being swaged or displaced beyond their elastic limit to effect a gripping of the contact member. The inner walls of the flanges, which adjoin the elongate contact member, constitute metal guideways that assure a positive tracking of the collector shoe.
