Definitions

  • the present invention relates to loading equipment for hopper craft of the type provided with a loading conduit which is centrally disposed above the hopper.
  • Loading craft of the type having a central loading conduit may become unstable when the craft lists.
  • the material falls from the central conduit to the lower side of the craft, which worsens the list.
  • the objects of the present invention are achieved by providing a distributor for the central conduit of a loading craft, with means so to move the distributor as to direct material toward the side of the craft opposite that which is lower when the craft lists.
  • a servomechanism for moving the distributor is provided, which automatically alters the position of the distributor upon rolling motion of the craft about its longitudinal axis.
  • This servomechanism may comprise a weight and a linkage system.
  • the distributor has a wide mouth elongated in a horizontal direction, the distributor being mounted on the craft for vertical swinging movement about a horizontal axis that extends lengthwise of the craft, the servomechanism being adapted to tilt the wide mouth of the distributor in directions opposite to the direction of roll of the craft.
  • H6. 11 is a somewhat schematic cross-sectional view through a hopper craft of the type to which the present invention may be applied, which hopper craft is loaded through a central overhead conduit;
  • FIG. 2 is a schematic top plan view of a distributor according to the present invention.
  • FiG. l is a view similar to HG. l but showing the distributor of FIGS. 2 and it applied thereto and hence illustrating the combination of the present invention.
  • FIG. is a schematic view of a weight-and-linlrage servomechanism for swinging the distributor in the direction opposite the direction of roll of the craft.
  • a hopper craft l listing in the water and having two air chambers 2 and It with a hold or hopper 4i therebetween.
  • Hopper d is loaded through a horizontal conduit 5 which is centrally disposed above the hopper and extends fore and aft of the craft.
  • the longitudinal vertical midplane of the craft is indicated at X-)t.
  • a distributor 7 is provided for the material from conduit s.
  • Distributor 7 has an outlet ti in the form of a horizontally elongated slot and is mounted for vertical swinging movement about a horizontal axis lying in the plane it-0i, by means of a pivotal connection it.
  • the path of flow of material through conduit 55 and out through distributor 7 is indicated sequentially by the arrows tm, 45b and dc.
  • H6 n example of servomechanlsm to swing distributor 7 oppositely from the list of the craft is shown in H6. 5.
  • a weight illil depends from a rod ill which is connected to distributor 7 through further rods l2 and H3 that together comprise a linkage system.
  • ltod Jill is pivotally mounted on the craft at fixed pivot lid for vertical swinging movement about a horizontal axis which is parallel to plane X-)( and disposed intermediate the ends of the rod ll ll.
  • Rod llll is pivotally connected to rod 12 at l5, and rod 112 is pivotally connected to rod 13 at 116.
  • Rod H3 is rigidly connected to distributor 7.
  • the distances between the connections lid, l5, lid and 9 are so chosen that the angular rate of tilt of distributor 7 is substantially greater than that of the craft upon listing. Specifically, the vertical distance from lid to id is greater than the vertical distance from 9 to lid.
  • Loading equipment for a craft having a hopper comprising a material-loading conduit which is centrally disposed above the hopper, a distributor for directing material from the conduit toward one side or the other of the hopper, and means responsive to list of the craft to move the distributor to direct material toward the higher side of the hopper.
  • said responsive means comprising weight means mounted for vertical swinging movement on and relative to the craft about a horizontal axis parallel to the length of the craft, and link means interconnecting the weight means and the distributor.
  • said link means comprising means to tilt the distributor at an angle opposite to and greater than the angle at which the craft lists.
  • said responsive means tilting the distributor at an angle opposite to and greater than the angle at which the craft lists.
