  • ROBERT HrRAMSEY OF PHILADELPHIA, PENNSYLVANIA.
  • My invention relates to an improved cartruck shifting apparatus, whereby car-loads of freight or passengers may be transferred from a broad to a narrow gage road, or vice versa, without breaking bulk, the general plan employed being that of removing the car-
  • the invention consists in combining inde pendent side rails and independent shiftingtrucks with the rails of the difi'erent gages of road, arranged centrally the one within the other and in the same plane, the said side rails being arranged, with respect to the central main rails, in a different plane or grade, withan incline at each end running into the same plane, so that as the cars traverse the tracks the side trucks receive and sustain the body of the car, while the main trucks, by reason of the difference in grade, drop from their places, and allow trucks of a difl'erent gage to be substituted instead, or trucks removed for repairing purposes.
  • B represents the main track
  • a Athe independent side tracks which side tracks, as shown, are upon a level with the main portion of the main track, while the main track at the point where the shifting is eifected is depressed below the leyel. of its line-grade and that of the side tracks, and has an incline at each end leading again into the plane of the said side tracks and main body portion.
  • the two sets of rails of different gage the narrow gage being arranged centrally between-the broad gage; and upon the side tracks, upon each side of the main rails, are arranged two rails for the shiftingtrucks.
  • 0 is the car-body, connected with the trucks D by the king-bolt G; E E, the two independent shifting-trucks, arranged upon the side rails; and F F, cross-beams extending from sidetruck to side truck beneath the carbody, and adapted to sustain the weight of the latter when the differential grade has effected the separation of its own trucks.
  • the cross-beams F are adjusted then at each end of the car transversely to the tracks, so as to rest upon the side trucks and pass beneath the car-body in position to sustain the same.
  • the car and. trucks are then pushed together across the difierentially-graded portion, and as thetrucks D of the car pass down the incline into the depressed portionof the main track they separate from the king-bolts of the car-body, which is sustained upon the crossbeams F resting upon the side trucks.
  • the main track is depressed to secure the incline, while the side tracks are level.
  • any arrangement of differential grade, as between the side and main tracks, would secure the same result-as, for instance, the main tracks might be level and the side tracks elevated. I prefer, however, the arrangement shown, as it is easier to move the car along the level road and the trucks up the inclines than to move the loaded car up the incline.
  • every car-body must be provided with at lea-st four unsightly wheels, which have to be carried everywhere the'car travels, and these are not only expensive and unsightly, but do not form a sufficient support for a loaded car; secondly, these wheels, to be made strong enough, have to be close up or flat against the body of the car, and in cars of different widths these wheels would not register with the inclined elevated rails; and, thirdly, the whole bulk of car-body and contents has to be hit ed, which involves not only a greater traction but an unnecessary strain upon the framing carrying the single elevated side rails.
  • the transverse permanent connection of the side trucks, in Tisdales device also permits the shifting of 1 only. one car at a time, which car has to be backed up, shifted, and then placed upon a siding.
  • My independent and disconnected side trucks combined with the tracks, graded as described, with two inclines, one at each end, permit several or all the cars of a train to be shifted without even uncoupling the cars, each car leaving successively one set of trucks in the depression and taking up another, and thus shifting the train in a nearly automatic manner by simply passing over the apparatus.
