Abstract: A railway vehicle wear member is provided between a pair of relatively movable components of the railway vehicle, wherein such wear member has a rigid planar supporting portion used to support a polymeric antifriction wear material and an extension which comprises the planar supporting portion and is formed in position against one of the relatively movable components to hold the wear member against a particular movement relative to the one component.

Abstract: A wear member for use between a pair of relatively movable components of a railway vehicle is provided where the wear member comprises a metal support adapted to be supported on one of the pair of components and a liner attached to the metal support wherein the liner is made of a polymeric matrix material which is reinforced by a metal structure having openings therein and such metal structure is disposed substantially centrally between opposed surfaces of the polymeric material and the opposed surfaces include a smooth antifriction wear surface engageable by the other of the pair of relatively moveable components; and, the liner is attached in position by metal members extending between the metal structure and the metal support through polymeric material disposed therebetween with a plurality of welds welding the metal members in position between the metal structure and the metal support.

Abstract: A pedestal liner for a pedestal truck of a railway vehicle is provided wherein such pedestal liner is of roughly U-shaped configuration having a bight and a pair of parallel legs. A continuous uninterrupted backing material defining the bight and parallel legs, and a first antifriction material for the bight fixed against the backing material to engage a vertically disposed planar guide surface of an associated journal box. A second antifriction material for the parallel legs fixed against the backing material to engage vertically disposed parallel side surfaces of the journal box which are disposed on opposite sides of the guide surface with the backing material providing optimum structural support for the antifriction materials and the first and second antifriction materials having different wear characteristics determined by the different wear rates to which they are subjected.

Abstract: A polymeric flexible hose construction and method of making same are provided wherein such hose construction comprises a tubular wall defining a main longitudinally extending passage for conveying a fluid therethrough and a second wall adjoining the tubular wall and defining a second longitudinally extending passage for an electrical conductor with the second wall having a wall portion common with the tubular wall.

Abstract: A fluid conduit assembly is provided and comprises a first and second conduit adapted to be easily connected and disconnected, a first electrical connector device carried by the first conduit and a second electrical connector device carried by the second conduit, and means locking the devices together with the first and second conduits connected with the locking means assuring electrical continuity through the electrical devices even upon exerting forces tending to pull the conduits apart.

Abstract: Apparatus for producing a continuous flexible reinforced tubular conduit is provided and utilizes a plurality of elongated rigid mandrels each having a non-yielding outside surface and such mandrels are moved continuously through a fabrication area while operatively associated in aligned end-to-end relation where at least one wire is formed around the mandrels in a continuous non-rotating helical coil. An extruder head is provided and extrudes a plastic tube around the coil which is urged and bonded thereagainst to define a conduit whereupon the conduit is subsequently separated from its associated mandrel.

Abstract: Method of severing a flexible reinforced elastomeric conduit supported on a plurality of elongated rigid mandrels is provided so that each mandrel has a length of conduit therearound which is approximately equal to the length of the mandrel.
