Definitions

  • This invention relates to improvements in mine car sealing devices, particularly for sealing the drop bottom doors of mine cars used for transporting coal or other materials from a loading point to a point of discharge, where such materials are discharged throughthe' bottom of the car upon release of the drop bottom doors therein.
  • a further object of the invention is to improve the sealing of the drop bottom door from end to end thereof, not only between the wheel. hoods, but also along the inside faces or vertical walls of the hoods. All large capacity four-wheel drop bottom door cars have vertical wallsv on wheel hoods with respect to which the doors must be sealed, as well as between the hoods, for effective sealing of the doors.
  • a side bar eave strip may be attached to the side sill structures at the inner edges of the flare plates to provide extensions thereon which will project inwardly in overlapping relation with the lateral edges of the doors to seal said edges against the leakage of coal or other loose lading therebetween.
  • These eave strips should extend between the wheel hood coverings, and preferably also along the inner faces of the coverings to the transverse tie plates that join together oppositely disposed wheelhoodcqverings if the latter terminate. at their. opposite edges inwardly of the opposite edges of the wheel hood coverings.
  • Fig. 1 is a side elevation of a fl-wheel car to which the invention maybe applied;
  • Fig. 2 is a longitudinal sectional view therethrough
  • Fig. 3 is a cross section thereof, on the line 3--3 in Fig. 2;
  • Fig. 4 is a similar view on the line 4--4 in Fig. 2;
  • Fig. 5 is a cross section showing the invention applied to a modified form of car.
  • the wheels are designated generally by the numeral I, mounted on axles 2, which axles support the body by being connected with side sills 3, extending longitudinally of the car and laterally spaced on opposite sides of a bottom opening therein.
  • side walls 4 Connected with the side sills 3 and extending upwardly and outwardly therefrom are side walls 4, which extend lengthwise of the car and have closed opposite ends formed by end walls in the customary manner.
  • the side walls 4 are formed by flare plates which may be attached to the upper edges of the side sills 3 to discharge the lading in the body into the center opening formed between the side sills 3 that are spaced at opposite sides of the body.
  • the slope of the flare plates or side walls 4, is in a plane which intersects the wheels I, appreciably below the upper edges thereof.
  • Each of the wheels is enclosed within a wheel hood covering 5, that has an inner wall 5, attached to the adjacent side sill 3.
  • Oppositely disposedwheel hood coverings 5 are connected together by transverse tie plates 5, that extend from side to side thereof over the axles 2.
  • the bottom opening of the car normally is closed by a series of interconnected doors designated generally at 8, 9 and Ni, each of which is hinged about a transverse axis, and the rear door is latched for dropping to release the series of doors for opening movements.
  • the rearward door holds the other doors of the series in closed relation to confine the lading therein.
  • Each of the doors 8IU comprises a plate which extends transversely between the side sills 3 and has upturned opposite edges, which may be formed by separate side bars ll, attached: thereto, and which form the opposite edge portions of the door. These edge portions are dis.- posed in relatively close relation to the inner. faces of the side sills, as shown in Figs. 3 and 4;
  • I have provided an eave strip [2, over each of the cracks, and secured to the inner face of the web of the adjacent side sill 3, in any suitable manner as by welding.
  • the upper face of this eave strip should slope downwardly to shed the lading into the central opening.
  • This eave strip I2 extends lengthwise of each side wall 4, substantially at the inner edge of the flare plate, and may be extended, if desired, as indicated at l3 and 13' over the inner face of the wall 6 on the wheel hood 5, to the adjacent lateral edges of the transverse tie plate I, as shown in Fig. 2.
  • the eave strips I2l3 project inward sufficiently to overlap appreciably the cracks between the edges of the doors and the inner faces of the side sills to prevent the sifting of fine lading therebetween.
  • These eave strips should be mounted substantially at the inner edges of the flare plates to form continuations thereof, for directing the material into the central opening of the car and yet are sufficiently high above the supported positions of the doors to permit the latter to move upward in their closing movements.
  • the invention is shown in Fig. 5, as applied to a modified form of car structure in which the side sill is designated at M, and has a side wall flare plate l5 with a downward extension [6 attached to the inner face of the side sill M.
  • the eave strip is designated at I7, and is secured to the extension H3, adjacent the inner edge of the side wall flare plate [5.
  • the drop bottom door is designated at l8, and has a plate l9 secured to each lateral edge and extending upwardly toward the eave strip ll adjacent the inner face of the side sill It. may be provided in a car or vehicle having relatively high side wall flare plates that substantially clear the wheels.
  • each eave strip extending lengthwise of each side sill structure and attached thereto and projecting laterally therefrom in overlapping relation with the adjacent crack, each eave strip including a solid bar having a downwardly inclined upper face for shedding lading and having an upright outer face bearing laterally against the side sill structure with said upright outer face projecting at least partially below the inclined upper face.
  • each eave strip attached to each of the side sill structures at the inner face thereof and extending lengthwise thereof in overlapping relation
  • each eave strip comprising a bar separate from the side sill structure, said bar having a substantially fiat face abutting against the side sill structure with said face extending substantially throughout the height of the bar.
  • a drop bottom door for clOsing said opening and having opposite edges thereof in sealing relation with the opposite side sill structures with cracks therebetween
  • the combination of an eave strip attached to each of the side sill structures at the inner face thereof and extending lengthwise thereof in overlapping relation with said cracks, each of the eave strips comprising a bar attached to the side sill structure, said bar having a substantially flat face abutting against the side sill structure with said face extending substantially throughout the height of the bar and having a downwardly sloping upper face and arranged adjacent the inner edge of the side walls of the body.
  • each eave strip including a solid bar having a downwardly inclined upper. face for shedding lading and having an upright outer face bearing laterally against the side sill structure with said upright outer face projecting at least partially below the inclined upper face, said bar being welded at the top and bottom edges thereof directly to the inner face of the adjacent side sill structure.
  • a vehicle having a lading body with side sill structures separated and having a bottom opening therebetween for the discharge of lading therethrough, wheels for supporting the lading body, longitudinally spaced wheel hood coverings in the lading body on opposite sides thereof over the wheels, said body having side wall flare plates between the wheel hood coverings, doors for closing the bottom opening and extending between the oppositely disposed wheel hood coverings and the side sill structures, said doors having upturned end portions thereon, the combination of eave strips separate from the side sill structures and sidewall flare plates extending longitudinally thereof substantially throughout the major portion of the length of the doors, each of said eave strips comprising a solid bar welded at the top and bottom edges thereof directly to the inner face of the adjacent side sill structure, said bar having portions thereof upwardly inclined over the inclined end portions of the door, said eave strip projecting laterally in overlapping relation with the adjacent edge of the door.
