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 pointto a point of discharge, where such materialsfare discharged through the bottom of the Acar uponl 'releasev of the drop bottom doors therein. f .T
  • The'object of this invention is to improve the construction of mine cars, especially'of large capacity, andparticularly the means for sealing the lateral edges of the drop bottom doors, whereby a wide door opening will be sealed effectively at its lateral edges when the'do'or is closed against the leakage of coal therethrough.
  • This object maybe accomplished.' according to certain embodiments of ythis invention, by the provision of means provided in cooperating relation withthe edge of the door and the adjacent. portion of the car 'structure in wiping relation with the opposed surfacesv therebetween for sealing effectively the crack therebetween at earch opposite edge of the door and without interfering with the normal opening and closing actions of the latter.
  • a wiping action can be accomplished in various ways, as, for instance, by a flexibleA or yieldable :element Asupported by one of the cooperating members in position to overlap or bear upon the other to prevent theleakage of coal or loose lading through the crack.
  • Fig. 1' is a side elevation of amine'car showing the inventiony applied thereto; Y Y
  • Fig. 2 is a detail transversey section through a portion of the car on the line 2-2 of Fig. 1, showing one form of sealing means for the edge of the door; and.
  • Figs. 3 to 11 are similar views showing other forms of sealing means that may be used. n
  • the invention is shown as applied to a mine car of the four-wheel type adapted to travel n a track formed by rails R.
  • the car is shown as comprising a body having side and end walls l and 2 supported on side sills 3, at each opposite side of the body.
  • the frame structure of the car comprising the side sills 3 and the combined end sills and bumpers Il, is supported on wheels 5, adapted to travel on the track R.
  • yThe car illustrated is of the bottom dumping type, the space between the side sills 3 being open, except as it is closed bydrop bottom doors generally designated E, three of which are shown. These doors 6 are latched in closed positions and are adapted to be released to discharge the lading from the car. f'
  • Each door 6 extends from side-to-side ofthe lading body between the opposed side sills 3. with a crack between each edge of the door 6, andthe adjacent side sill, as will be evident inthe drawings.
  • each edge of thedoor ⁇ 6 is provided with a iiange onthe edge thereof, eitherformed integral with the door plate or separate, as shown, and indicated at 'l in Fig. 2.
  • the flange bar 'l extends lengthwise of the ldoor plate and is welded thereto.
  • a substantially straight bar may be vused for-the purpose, the door 6 also being substantially straight and plane throughout the major'portionV of its length.
  • This ange bar 'l at each edge of the door 6 is adapted to extend up into the space between the opposed side sills when the door is in closed position.
  • the doors are closed by closing devices mounted in the track R, and are latched at their free edges. This requires thev upward movement of the doors to points above the closed positions thereof in the latchlng or unlatching of the doors.
  • this sealing ymeans is provided by a leaf spring, generally designated at 8, which may be formed of a strip of spring steel extending lengthwise throughout the length of the side sill 3, or the door 6, and attached at 9, as by welding, riveting orl any other suitable 3 manner, to the adjacent under edge of the side sill 3.
  • the strip 8 at its upper inner edge bears in overlapping relation with the upper edge of the flange bar 'l on the door 6, at each opposite edge of the latter, and overlapping the space between these parts, prevents the lading from sifting through the crack therebetween.
  • this stripI 8 will yield to permit relative upward and downward movementof the door with respect to the side sill, while maintaining the sealing relation whenever the ⁇ door is in closed position.
  • This sealing spring maybe shortenedas indicated at I0, in Fig. 4, if desired, so as to have wiping relation with the face of ⁇ the strip l, instead of with the upper edge thereof, as in Fig. 2.
  • FIG. 5 Another form thereof is shown in Fig. 5, as indicated at l I, also bearing against the face of the door vflange 1, but folded over in U-shape -with thewiping edge intermediatev the width ofthe spring strip.
  • the lower edge ofthe strip ll is secured rigidly-to the'side sill 3, while the upper edge thereof is free but bears against the inner face of the sill,'so as-to yield inwiping relation with the adjacent faceof the flange 1.
  • FIGs. 3 and 6 are shown the use of brushes inwipingv actionbetween the adjacent portions of thedoor and the 'side'silL
  • Fig. 3 shows a brush I2 securedvto the under face of the side sill 3, and preferably formed as a wire brush with the wire bristles relatively close together in position for wiping action with the lateral face of the ange l.
  • the wire brush i3 is supported directly vupon the'innerl faceof the side sill 3, in wiping relationwith the lateral face of the flange bar 1.
  • the sealing. member is carried by thedoor.
  • the'sealing member 25 is 'in the form of a leafspring secured at one edge to the 4ilange bar 'l fof' the door,A while its opposite edge is in -wipingrelation with the under edgefof the side sill 3.
  • the sealing member 26 is secured over the upper edge of the ange Ibar 'l and also extends into' wiping relation with the lower edge of the side sill.
