Definitions

  • a railbound car with a bottom hingedly connected to the car body along a longitudinal edge of one side thereof and supportable on a rail or rails describing curves constituting partial helices about, and at constant radial distance from, the longitudinal axis about which the bottom is hinged.
  • the car body is guided and supported by beams with rolls and an opening motion is guided by the rail or rails.
  • This invention relates to an arrangement adapted for discharging goods from a railbound car through its bottom which by hinges is connected with the remaining car body, said body during the emptying operation being supported by beams with rolls, in such a manner, that the bottom by means of one or several supporting wheels rests against one or several rails which describe curves for rendering the bottom possible to be lowered by its own weight and the weight of the goods when the car is being moved along its line, and thereby to effect an emptying operation.
  • the hinges are mounted at the front edge of the car body, and the rail or rails describe steep downward curves in the vertical plane.
  • goods fall down over the rails and to the side thereof, which involves the risk that the rails are subjected to impacts and damage, particularly in the case of greater pieces of goods, as for example in ore-mining.
  • the car subsequent to an emptying operation cannot be moved back on the same line, but for this purpose a special dead-end siding must be laid to the side of the discharge place, which involves high expenditures.
  • the hinges are mounted between one longitudinal side of the bottom and of the car body, and the curves for the rail or rails constitute helical lines running about and at a constant perpendicular distance to the line which is generated by the shaft of the hinges.
  • FIGS. 1 and 2 show one of the embodiments seen from the side and from above respectively
  • FIG. 3 shows a section along the line A-A in FIG.
  • FIGS. 4 and 5 show the other embodiment seen from the side and from above respectively.
  • FIG. 6 shows a section along the line B-B in FIG. 5.
  • a car for piece goods comprises a car body 1 which by hinges 2 provided below on one longitudinal side is secured to a bottom 3. On the lower surface of said bottom two pairs of bearing blocks 4 are mounted, in which blocks wheel axles 5 with wheels 6 are supported. Said wheels usually carry the car during transports on a track 7 which terminates at a pit 8 serving as the discharge place.
  • a central supporting wheel 9 s provided, the axle of which is supported in a bearmg block 10.
  • the wheel 9 is applied only during the emptying operation proper and co-operates thereby with a. special supporting rail 11.
  • guide bars 12 which are provided at the upper edge of the longitudinal sides of the car body and during the emptying operation rest against rolls 13 on supporting beams 14 mounted on both sides above the pit 8.
  • the arrangement according to the invention operates as follows.
  • a number of abovedescribed cars which are coupled together by couplings (not shown) secured on the car body, are driven, for example by a locomotive, on the track 7 to the pit 8.
  • its car body is supported and guided by the beams 14 disposed on the same level as the lower surface of the guide bars 12.
  • the bottom 3 is supported by the supporting wheel 9 resting against the supporting rail 11.
  • the said supporting rail extends past the pit in a curve having its starting point directly before the end point of the track 7 and terminating on the opposite side of the pit where the track 7 continues.
  • the supporting rail 11 is laid in a mirror symmetric manner on both sides of the central line of the pit, and according to the invention it is formed after a curve which constitutes a helical line at a constant perpendicular distance from the line generated by the shaft of the hinges.
  • the pitch of the helical line varies between positive and negative infinity values (when no closing or opening movement takes place) and between a positive and a negative final value (in the case of a maximum closing and opening movement respectively). Furthermore, the helical line moves only part of a revolution about its central line, in this case about 45 which is a practical value.
  • the car bottom is divided into two halves, a front half 15 and a rear half 16. Both of these halves are hinged about hinges 2 below on one longitudinal side of the car body, and each of said halves is provided on the lower surface with wheel axles 5 and wheels 6 mounted in bearing blocks 4.
  • the wheels rest permanently against the two rails 17 and 18 of the track 7, which rails at the discharge place from some kind of parallel helical lines about and at a constant perpendicular distance to the path described by the shaft of the hinges when a car is passing.
  • the car body 1 is guided and supported by the beams 14, and the opening motion of the bottom halves 15 and 16, thus, need be guided only by one rail, preferably the rail 17 which is located at the greatest distance from the hinges 2 and, therefore, is subjected to the smallest load.
  • the track on which the emptying is to be made has no rail 18.
  • said railway vehicle having at least one bottom member hingedly connected to a longitudinally extending side of the vehicle which is adapted to be opened for side unloading said vehicle,
  • said hinged bottom member having at least one wheel which rides upon a supporting rail that normally supports said hinged bottom member in a closed position
  • said supporting rail at said unloading station defining a path which permits downward rotation of said bottom member about its hinge to open the bottom of said vehicle at said unloading station while said vehicle is otherwise supported at least in part by said vehicle means.
  • said supporting means includes a pair of parallel rails extending along the respective sides of each vehicle at least at said unloading station, and means on said vehicle engaging with said rail to support said vehicle.
  • said vehicle is provided with at least four wheels which normally support and convey said vehicle over a pair of track rails, the wheels on at least one side of said vehicle being operatively connected to said hinged bottom member, said track rail for said wheels on said one side being curved helically downwardly and laterally at said unloading station to lower said wheels on said one side and thus also open said hinged bottom member.
  • a railway car adapted for automatic dumping of its load as it passes an unloading station at which the upper body portion of the car is supported at a predetermined level by a support means and at least one bottom actuating car wheel is supported on one rail whose distance from said predetermined level increases at said unloading station to thereby lower the level of support of said car wheel relative to said upper body portion,
  • said car comprising an upper body portion having fixedly joined side and end walls and at least one bottom member hingedly connected to one side wall of said upper body portion,
  • said bottom actuating wheel being operatively connected to said car bottom member whereby said lowering of said car wheel at said unloading station relative to said predetermined level opens the car bottom to discharge its load to one side of the track rails.
  • the railway car of claim 8 which includes four wheels each operatively connected to said hinged bottom member and arranged to support said car on a pair of track rails and one of said four wheels constitutes said bottom actuating car wheel.
  • the railway car of claim 8 which includes four wheels each operatively connected to said hinged bottom member and arranged to support said car on a pair of track rails and said bottom actuating wheel comprises a fifth auxiliary wheel adapted to run along a helically curved guide rail at said unloading station.
  • the railway car of claim 8 which includes two hinged bottom members each having a bottom actuating wheel operatively connected thereto.
