  "abstract": "An apparatus such as a shuttle bin includes an upper frame, a lower frame hingeably connected to the upper frame, a storage body operatively connected to the upper frame for storing material and a roller assembly operatively connected to the upper frame. The roller assembly is adapted to draw the storage body taut to unload the material stored in the storage body as the upper frame hinges away from the lower frame. The storage body may be formed of a pliable material such as a mesh or canvas.",
  "claims": [
    "1. An apparatus, comprising: an open upper frame having a first end and an opposite second end and a first side and an opposite second side; a lower frame having a first end and an opposite second end: the second end of the lower frame hingeably connected to the second end of the upper frame; a pliable storage body operatively connected between the upper frame and the lower frame; the pliable storage body for storing material, the pliable storage body formed of a pliable material; a roller assembly operatively connected to the upper frame at the first end; wherein the roller assembly is adapted to draw the storage body taut to unload the material stored in the storage body as the upper frame hinges away from the lower frame; a loading assembly operatively connected to the lower frame at the first end and configured to deposit materials through a top of the open upper frame into the pliable storage body; wherein in a store position the first end of the upper frame is adjacent the first end of the lower frame and the top of the open upper frame is open: wherein in a dump position the upper frame is pivoted up and away from the first end of the lower frame such that the pliable storage body is pulled taut.",
    "2. The apparatus of claim 1 wherein the pliable material is a mesh material.",
    "3. The apparatus of claim 1 wherein the pliable material is a canvas material.",
    "4. The apparatus of claim 1 further comprising a cylinder operatively connected between the upper frame and the lower frame for raising and lowering the upper frame.",
    "5. The apparatus of claim 1 further comprising a second roller assembly operatively connected to the lower frame to assist in drawing the storage body taut.",
    "6. The apparatus of claim 1 wherein the loading assembly comprises a backboard and a support surface extending from the backboard.",
    "7. The apparatus of claim 6 wherein the support surface is adapted to be vertically raised relative to the lower frame.",
    "8. The apparatus of claim 7 wherein the loading assembly further comprises a pivot member adapted to operatively pivot the support surface relative to the lower frame to allow for loading of the material into the storage body.",
    "9. The apparatus of claim 8 wherein the loading assembly further comprises a cylinder for raising the support surface relative to the lower frame.",
    "10. An apparatus, comprising; an open upper frame; a lower frame hingeably connected to the upper frame; a first expandable metal mesh side on a first end of the upper frame; a second expandable metal mesh side on an opposite second end of the upper frame; a cylinder operatively connected between the upper frame and the lower frame to pivot the upper frame relative to the lower frame; a storage body operatively connected to the upper frame for storing material, the storage body formed of a breathable pliable material; a roller assembly operatively connected to the upper frame; wherein the roller assembly is adapted to draw the storage body taut to unload the material stored in the storage body as the upper frame hinges away from the lower frame; a loading assembly operatively connected to the lower frame for loading the material into the storage body; wherein the loading assembly is adapted to be raised above the upper frame to load the material into the storage body; wherein in a storage position the upper frame is closed relative to the lower frame: wherein in a dump position the upper frame is pivoted open relative to the lower frame and the storage body is pulled taut: wherein in transitioning from the storage position to the dump position the upper frame is pivoted open and away from the lower frame using the cylinder.",
    "11. The apparatus of claim 10 wherein the storage body comprises mesh.",
    "12. The apparatus of claim 10 wherein the storage body comprises canvas.",
    "13. The apparatus of claim 10 wherein the loading assembly comprises a backboard and a support surface extending from the backboard.",
    "14. A method for operating a shuttle bin, comprising: providing a shuttle bin comprising (a) an open upper frame having a first end and an opposite second end and a first side and an opposite second side, (b) a lower frame having a first end and an opposite second end, (c) the second end of the lower frame hingeably connected to the second end of the upper frame, (d) a pliable storage body operatively connected between the upper frame and the lower frame, the pliable storage body for storing material, the pliable storage body formed of a pliable material, (e) a roller assembly operatively connected to the upper frame at the first end, (f) wherein the roller assembly is adapted to draw the storage body taut to unload the material stored in the storage body as the upper frame hinges away from the lower frame, (g) a loading assembly operatively connected to the lower frame at the first end and configured to deposit materials through a top of the open upper frame into the pliable storage body, (h) wherein in a store position the first end of the upper frame is adjacent the first end of the lower frame and the top of the open upper frame is open, (i) wherein in a dump position the upper frame is pivoted up and away from the first end of the lower frame such that the pliable storage body is pulled taut: loading the materials into the loading assembly of the shuttle bin; raising the loading assembly above the top of the upper frame of the -shuttle bin; pivoting the loading assembly during the raising of the loading assembly to dump the materials over the upper frame of the shuttle bin and into the pliable storage body; lowering the loading assembly; pivoting the upper frame away from the lower frame; rolling the pliable storage body using the roller assembly as the upper frame pivots to assist in dumping the material from the pliable storage body.",
    "15. The method of claim 14 further comprising conveying the shuttle bin from a first location to a second location before dumping the material from the pliable storage body.",
    "16. The method of claim 14 wherein the pliable storage body comprises mesh."

  "description_excerpt": "This application claims priority under 35 U.S.C. §119 to U.S. Provisional Patent Application No. 61/027,657, filed Feb. 11, 2008, and herein incorporated by reference in its entirety.\n\nThe present invention relates to unloading of materials.\n\nThe present invention provides for a method and apparatus for the unloading of materials. To assist in understanding the present invention, problems which may be addressed by the present invention are discussed in the context of grass clippings. The present invention is not, however, limited to grass clippings as it may be used for unloading of other types of materials, including, but not limited to, particulate matter or other types of materials which do not flow well.\n\nIn lawn care services, grass clippings are collected, transported, and unloaded. The disposal of grass clippings is a part of the lawn care service. Unloading a trailer full of grass clippings can take 5 to 10 or more minutes to manually unload. This aspect of handling grass clippings adds cost and time to lawn care services.\n\nAnother problem with transporting and unloading grass clippings is that the grass quickly begins to decompose. Decomposing clippings clump and cling together. This also results in an odor and grass clippings which stick to containers in which the clippings are transported as well as individuals who manually unload the clippings. It is further observed that grass clippings, or other types of chopped forage material do not flow well, thus even if dumped from a container, manual labor is needed to more completely remove the material from the container.",
