Abstract
A material transfer apparatus and method, the apparatus having a material separating container, a filter unit, a vacuum unit and an exhaust unit, all mounted on a mobile conveyance. Air, carrying the materials to be transferred, is drawn through pneumatic tubing into the separating container where large and small materials are separated, and then into the filter where it is filtered for re-entry into the atmosphere.
Claims22
An apparatus for collecting and transferring materials, comprising:
- a foundation;
- vacuum means mounted upon said foundation for collecting materials in an air stream;
- container means, pivotally bracketed to said foundation, for receiving collected materials, said container means comprising a vacuum inlet, means for separating a first portion of the collected materials from the air stream, and an exhaust outlet;
- means for raising and lowering said container means with respect to said foundation;
- means, mounted upon said foundation apart from said container means, for filtering said air stream, said means for filtering comprising a filter inlet connectable to said exhaust outlet of said container means, and further comprising a means for transmittiing a filtered air stream from said filtering means;
- automatic means for disconnecting and reconnecting said filter inlet from said exhaust outlet of said container means when said container means is raised and lowered, respectively;
- and
- exhaust means operably connected to said vacuum means for reducing noise during the collecting of materials,
- wherein said vacuum means is operably connected to said means for filtering, and said container means, said filtering means, said vacuum means, and said exhaust means are all mounted on a mobile conveyance.

A mobile apparatus for collecting and transferring materials, comprising:
- a foundation;
- a substantially closed container, pivotally bracketed to said foundation, for receiving materials, said container comprising an exhaust outlet;
- means for raising and lowering said container with respect to said foundation;
- means for filtering mounted upon said foundation apart from and in fluid communication with said container, said means for filtering comprising a filter inlet;
- a cradle upon said filter inlet;
- a connector upon said exhaust outlet, engaged with said cradle when said container is lowered and disengaged from said cradle when said container is raised;
- a tube in fluid communication with said container;
- vacuum means, mounted upon said foundation, for moving an air stream through said tube, through said container, and through said filtering means;
- means for slowing the movement of the air stream through said container;
- and
- exhaust means, operably connected to said vacuum means, for muffling exhaust noise of the air stream;
- whereby materials are collected in the air stream for movement through said tube to said container and from said container to said filtering means, and wherein gravity separates at least some of the material from the air stream when the movement of the air stream is slowed.

A method of collecting and transferring materials, comprising:
- generating an air stream;
- collecting materials in the air stream;
- receiving collected materials in a container, the container comprising a vacuum inlet and an exhaust outlet;
- separating a first portion of the collected materials from the air stream in the container;
- filtering the air stream with a filter unit comprising a filter inlet connected the exhaust outlet of the container means;
- transmitting a filtered air stream to an air exhaust;
- raising the container to dump collected materials therefrom and to automatically disconnect the filter inlet from the container exhaust outlet;
- lowering the container to reconnect the filter inlet with the container exhaust outlet;
- and
- reducing noise in the exhaust.
