Spacers Patents (Class 238/105)
  • Patent number: 9644323
    Abstract: An assembled section of a train rail track structure comprises an electrically isolating cross tie comprising a ‘c-face down’ open channel defining at least one of a plurality of holes, tabs and notches in a flange at a top thereof and in a plurality of sides thereof proximal to each end of the open channel cross tie. The assembled section also includes an angle plate configured with a horizontal portion and a vertical component to cover an end portion of the ‘c-face down’ open channel and directly fasten thereto via at least one of a plurality of holes, tabs and notches complementary thereto. The assembled track further includes a first section of electrically isolating cross ties comprising a first warning color closest a rail crossing and a second section of cross ties immediately beyond the first section comprising a second warning color and coordinated flashing and strobing lights attached thereto.

  • Patent number: 9556565
    Abstract: A train rail track structure system includes a c-face down steel channel cross tie defining a plurality of holes in a top wider web surface thereof and a protrusion with perpendicular faces extending from an underside of the top surface, the holes configured to pass a fixative and solidifying mixture into a ballast bed there beneath. The protrusion anchors the steel channel cross tie in the fixative and solidifying mixture and the ballast bed. The disclosed system also includes a c-face down steel channel connecting link defining a receptacle for at least one intermediate rail support member in a top wider web surface thereof. The link also defines tabs and notches proximal to both longitudinal ends of the steel channel connecting link configured to interleave with at least one steel channel cross tie and interlock the steel channel connecting link to the steel channel cross tie.

  • Patent number: 5507434
    Abstract: Apparatus for mounting an impedance bond or other device between a pair of spaced, concrete railroad ties employs a clamping plate which overlies and spans the ties, and a pair of clamping feet that are installed between the ties. Components interconnecting the plate and the feet draw the plate and feet toward one another to securely clamp the ties therebetween. The device to be mounted between the ties is secured to the undersurface of the plate and is thus held in a fixed position in the space between the ties. The spacing between the feet may be varied to accommodate different tie spacings, and the entire installation is accomplished without embedding fasteners in the concrete tie material.

  • Patent number: 4989782
    Abstract: A rail for a track for a wheeled vehicle is generally elongated and has a substantially "I" transverse cross section providing an upper rail head and a lower rail foot joined by a web. The rail head is provided with at least one and preferably two laterally spaced apart longitudinally extending apertures, which are adapted to receive alignment pins so that when the rails are coupled to each other substantially end on end, the pins extend between abutting ends of the rails to maintain the rails in an abutting and substantially aligned relationship. A track is also provided including spaced apart rails with a plurality of spacers extending between the spaced apart rails to maintain the rails in a predetermined spaced apart relationship. The spacers can be pivotally mounted on the rails, so that the rails are able to move and pivot relative to each other such as for the adjustment of gauge, packaging, and transport.
