Abstract: A conductor rail assembly for use in transit rail transportation systems to transmit electrical power to rail cars comprising a first and second support sections preferably of aluminum to give the rail assembly its rail-shape and conductivity and a cap section preferably of stainless steel to provide a wear resistant surface to prevent damaging of the conductor rail by collector shoes that extend from rail cars and run on the conductor rail. The first support section has a rib and the second support section has a concavity. In the assembly, the rib of the first support member preferably is disposed within the concavity of the second support member, portions of both support members preferably are friction fit or compression fit within the cap and a friction stir weld preferably is disposed on the bottom of the assembly along a joint between the first and second support sections.
Abstract: A compound railroad track wherein the head rail is easily replaceable without replacement of the supports, which comprise two extruded mirror-image L-shaped members, periodically spaced U-shaped separators, and a base plate, all suitably bolted and welded together.
Abstract: A train track bed includes an elongated slot therein and a track rail includes a bottom flange that is supported by the track bed. A bendable locking tab is formed on the bottom flange of the rail. The locking tab is bent into the slot in the bed to restrain longitudinal movement of the rail on the bed while the bottom flange of the rail is received between opposing rail-holding flanges on the bed that restrain other movement of the track. Preferably, the track includes oppositely extending bottom flanges formed of sheet metal folded back upon itself with each flange having a depending side wall at the outermost lateral extremity of the flange to form a recess between the side walls. A pair of raised support ribs extends from the track bed into the recess to engage the underside of the flanges to support the rail on the track bed. The side walls hide the raised support ribs from view.
Abstract: The present invention relates to a rail intended to constitute a tread for heavy duty rolling stock, such as gantry cranes, mounted on wheels or rollers and concerns more specifically a guide rail on which both center-flange wheels or rollers, and lateral-flange wheels, as used on railway lines roll, comprising, in section, two integrally formed spaced heads running parallel to each other, the two heads having vertical inner side walls and being separated by a horizontal intermediate channel whose bottom constitutes a horizontal connecting strip.
Abstract: Rail bonds providing electrical connections between adjoining and parallel rail lengths, between rail and external circuits, between rail and frogs, switches and the like include a rail bond terminal comprising a stranded conductor, an inner sleeve having a flared portion and secured to an end of the conductor, and a tapered outer sleeve having open ends into which the inner sleeve and conductor can be inserted. One end of the outer sleeve forms a head portion having an opening sufficient to receive the conductor to permit the conductor to be removed from the area of the end of the terminal to which a hammer is applied for driving the terminal into a rail or the like.
