Locomotive Shed Fixtures Patents (Class 104/51)
  • Patent number: 5245930
    Abstract: An emergency life saving vehicle (ELSV) for providing emergency services on a bridge independently of traffic conditions thereon. In particular, the ELSV conforms to the particular configuration of a bridge so as to ride along an otherwise unused portion of the bridge, and thereby circumvent any traffic which may have accumulated on the bridge. There are at least three different embodiments of the ELSV, each embodiment corresponding to a particular bridge structure. A first embodiment has a raised center portion so that the ELSV is able to straddle a lane dividing wall on a single span bridge; a second embodiment is adapted to straddle a space between two adjacent and parallel spans of a two span bridge by simultaneously riding on the interior walkways of each span; and a third embodiment rides along the interior walkways and retaining walls of a two span bridge.

  • Patent number: 4494462
    Abstract: Heating apparatus is described that is particularly adapted for thawing frozen particulate material in railroad hopper cars. The apparatus is a low profile, fuel-fired heater adapted for installation between rails traversed by the hopper cars within a thawing shed. The construction employs heat-radiating metal plates forming an elongated gas-conducting chamber through which high velocity combustion gases are conducted. The arrangement of plates is such as to enhance the emission of radiant heat to the hopper car bottoms with appropriately positioned heat insulated regions to protect hopper car brake hoses, or the like, from damage caused by overheating.
