Skimmer and oil water separator
First Claim
1. A skimmer for an oil water separator, comprising:
- a stationary receiver box including means for slidably securing a weir plate to an outer surface of said stationary receiver box;
bracket means for supporting said stationary receiver box onto a interior surface of a tank containing water having oil floating of a surface thereof;
a slidable panel comprising a weir plate including a central vertical slot therein in slidable engagement with said stationary receiver box means for movably securing said weir plate having including a trough forming a horizontal weir extending across a selected width and depth of a top edge of said slidable panel;
said weir plate including a pair of spaced apart opposing side tabs extending from said weir plate in slidable cooperative engagement with a pair of floats removably secured to said tabs by a vertical side flanges including vertical slots therein for adjustably engaging means for securing each one of said vertical side flanges to a respective side tab of said weir plate;
said vertical flanges or said tabs including indicia for vertical adjustment of said floats with respect to said weir plate.

Abstract
A skimmer for removing a layer of oil floating on a surface oil contaminated water which subsequently concentrated and separated in an oil water separator which removes tramp oils or other fluids, such as hydraulic oils, with specific gravity less than that of the operating fluid are required to be removed from operating fluid such as water, lubri-coolants or other liquids. The skimmer supplies concentrated oil water composite fluid to a separator apparatus designed for use in industrial applications in which unwanted tramp oils or other fluids, such as hydraulic oils, with specific gravity less than that of the operating fluid are required to be removed from operating fluid such as water, lubri-coolants or other liquids.

3. A method of skimming oil from an oil/water solution, comprising the steps of:
-
attaching a stationary skimmer receiver box to an interior wall of a tank containing an oil/water composition; positioning said stationary skimmer receiver box so that a weir plate formed therein is suspended at a selected level in said oil/water solution by a pair of floats; attaching a float bracket including a vertical slot to a weir plate flange extending from each side of a weir plate held in cooperative sliding relationship with said stationary skimmer receiver box; said pair of floats moving vertically with respect to a selected water level pouring over said weir plate of said stationary receiver box; showing an indicator on a the weir plate flange pointing to indicia shown as a scale on said float bracket; and setting said weir plate flange at a selected level with an attachment bolt and nut disposed in a vertical slot formed in said stationary skimmer receiver box and said weir plate for slidably holding said weir plate at a selected level.
