Abstract
An improved particulate handler that includes one or more elastic sheets that are particularly effective in facilitating the easy and complete removal of particulate from transporters or containers such as railroad cars, dump trucks, chutes and the like. The combination of the elastic sheets and supporting walls overcomes the problem with sticking of particulates to the interior surfaces and facilitates smooth and easy movement and/or removal under the influence of gravity and changes in tensile stresses and stretch that develop in the sheets during loading, unloading and conveying.
Claims20
An improved particulate vessel having a bottom portion and a pair of opposed side walls extending from said bottom portion defining sides of said vessel, each of said side walls having upper extremities, and a plurality of sheets of intentionally stretchable non-stick material, each of said sheets having two opposite ends, one of said opposite ends of each of said sheets being attached to the upper extremity of a first one of said pair of opposed side walls and the other of said opposite ends of each of said sheets being affixed to the upper extremity of the other of said pair of opposed side walls, said sheets being disposed in partly overlapping positions thereby to normally cover only predetermined surfaces less than the entire interior of said vessel.
An improved particulate vessel having an essentially planar bottom portion residing in a first plane and a pair of essentially planar opposed side walls, each of the pair of side walls respectively defining a second plane and a third plane essentially parallel to each other and extending from said bottom portion and defining sides of said vessel, each of said side walls having an upper extremity defining a line lying in a plane essentially parallel to said first plane, and a plurality of sheets of stretchable urethane material, each of said sheets having two opposite ends, one of said opposite ends of each of said sheets being rigidly affixed at a first position of attachment to the upper extremity of a first one of said pair of opposed side walls and the other of said opposite ends of each of said sheets being rigidly affixed at a second position of attachment to the upper extremity of the other of said pair of opposed side walls, said sheets being disposed in partly overlapping positions thereby to completely cover predetermined surfaces of the interior of said vessel.
The method of loading and unloading a particulate transporter comprising the steps of:
- a. providing an improved particulate transporter having an essentially planar bottom portion residing in a first plane and a pair of essentially planar opposed side walls defining a second plane and a third plane and extending from said bottom portion and defining sides of said transporter, each of said side walls having an upper extremity defining a line lying in a plane essentially parallel to said first plane;
- b. positioning a plurality of elongated sheets of stretchable urethane material within said particulate transporter, each of said elongated sheets having a first end and a second end at opposite extremities of each of said sheets;
- c. disposing said elongated sheets of material within said particulate transporter to overlie the interior surfaces of said side walls while avoiding contact with at least a substantial portion of said interior surfaces when said particulate transporter is empty;
- and
- d. affixing said first end of each of said sheets to said upper extremity of one of said side walls and the second of said ends to said upper extremity of the other of said pair of opposed side walls.
