Abstract
A water table used for cutting metal is comprised of an array of slat bars, a floor part below the array of slat bars, a movable platform further below the floor part. The movable platform, by the use of height changing means, will move in order to change the volume available inside the water table which results in the actual lowering or raising of the level of water inside of the water table.
Claims21
A water table for cutting metal pieces, comprising:
- a container having a top open end and a liquid pool therein for collecting residue from cutting metal pieces;
- a support grid secured adjacent to said top open end of said container and adapted for receiving thereon metal pieces to be cut;
- an expanding member in said container, said expanding member being expandable so as to raise and lower a level of said liquid pool in said container to cover at least partially said support grid;
- filter means for filtering unwanted residue collected on a collecting surface;
- and
- said collecting surface having at least one inclined portion below said support grid, said inclined portion creating a liquid current thereon when the level of said liquid pool is lowered, so as to carry unwanted residue gathered from cutting metal pieces to said filter means.

- a container having a top open end and a liquid pool therein for collecting residue from cutting metal pieces;
- a support grid secured adjacent to said top open end of said container and adapted for receiving thereon metal pieces to be cut;
- and
- an ambient pressure compartment in said container, said ambient pressure compartment defined by a displaceable wall connected to a surface of said container by a flexible watertight skirt, said displaceable wall being displaceable for expanding said ambient pressure compartment so as to raise and lower a level of said liquid pool in said container to cover at least partially said support grid.
