Patent number: 5865282Abstract: 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.Type: GrantFiled: February 5, 1997Date of Patent: February 2, 1999Assignee: Alusuisse Technology & Management Ltd.Inventor: Joachim Gluck

Patent number: 5605209Abstract: 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.Type: GrantFiled: December 19, 1995Date of Patent: February 25, 1997Assignee: Howell CorporationInventors: Robin A. Clarke, William R. Heil, Robert S. Beale

Patent number: 5310032Abstract: 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.Type: GrantFiled: June 7, 1993Date of Patent: May 10, 1994Inventor: Dietmar G.
