Definitions

  • the present invention relates to hoppers having bottom doors and means to actuate the bottom doors, particularly to such hoppers which comprise the holds of ships.
  • Another object of the present invention is the provisionof hoppers in which the bottom doors may be swung vertically by the action of pumps that are useful in other operations.
  • Still another object of the present invention is the provision of hoppers having vertically swinging bottom doors which will be stable in position under adverse conditions such as the rolling of a ship.
  • Means are provided for supplying fluid, preferably water, under positive or negative pressure to chambers 14 and 15,
  • connections shown at 29 and 30 are prodescription, taken in connection with the accompanying dravving, which is a somewhat schematic transverse cross-sectional view of the hold of a barge or other ship embodyinga hopper according to the present invention.
  • a hopper 1 having sidewalls 2 and 3 and end walls 4.
  • a divider 5 having oppositely downwardly inclined upper walls 6 and 7 which are separated by an upright partition 8.
  • Upper walls 6 and 7 terminate downwardly respectively in upright sidewalls 9 and 10.
  • Arched sheets 11 and 12 are also provided in divider 5.
  • Each sheet 11 and l2 is approximately quarter-cylindrical,
  • the divider 5 is closed at each end by end walls 13 that may simply be portions of end walls 4 and that seal with the upper walls 6 and 7, the partition 8, the sidewalls 9 and i0 and the arched sheets-ll and 12.
  • the end walls 13, the partition 8, the upper wall 6 and the arched sheet ll thus define define a chamber 14 within divider 5.
  • the end walls 13 and the upper wall 7 and partition 8 and arched sheet 12 also define a chamber 15 within divider 5. Chambers 14 and 15 do not communicate with each other.
  • Oppositely vertically swinging hopper bottom doors [6 and 17 are mounted respectively for vertical swinging movement about horizontal axes l8 and 19 which are disposed intermediate the length of the doors and at the lower ends .of sidewalls 9 and 10 and which are concentric with arched sheets ll and 12 respectively.
  • the free end of door 16 thus cooperates with the lower edge of hopper-wall 2 to close the left side of hopper l as shown in the drawing, or in a downwardly swung position to open this side of the hopper.
  • the free end of door 17 cooperates in the position shown in the drawing with the lower edge of hopper wall 3 to close the right side of the hopper asshown in the drawing, or in a downwardly swung position to open this side of the hopper.
  • the door portions 22 and 23 have sealing strips 24 which slide against the concave surfaces vided through a portion of end wall 13 that bounds the respective chambers 14. and I5.
  • connection may be made to a pump such as the delivery water pump of a sand pump used in connection with a sand barge.
  • the capacity and pressure of the pump may be so high that it is not important whether there is any leakage between portions 22 and 23" and the sidewalls of their respective chambers 25 and 26.
  • the doors l6 and 17 may be swung vertically to open'or close them. Also, it will be noted that the pressure in the chambers 25 and 26 tends to hold the respective doors either in the open ,or closed position, so that the Iustrated in connection with a preferred; embodiment, it is to I swing of the doors relative to the ship will be damped when the ship rolls. Also, when the doors are closed, the latches 20 and evident that all of the initially recited objects of the present invention have been achieved.
  • a hopper having a bottom door mounted for vertical swinging movement about a horizontal axis, said axis being disposed intermediate the length of the door, a first portion of 1 the door on one side of said axis comprising a hopper bottom and a second portion of the door on the other side of said axis being in slidable contact with the walls of a chamber of which one wall is arcuate and .concentric with said axis, and means for supplying fluid under pressure to said chamber to swing said door vertically.
  • a hopper as claimed in claim 1 and latch means for releasably securing the door in closed position.
