Abstract

Abstract A skimmer for removal of a layer of oil or other floating pollutant from the surface of a body of water constructed in the form of a module employed with a desired number of similar modules for connection with a floating barge or other vessel for collecting and skimming off the oil when the barge or other vessel moves forwardly and discharging the collected oil or pollutant into storage tanks or the like incorporated into the barge or other vessel. Each oil skimmer module includes an open front receptacle having a horizontally disposed inclined front edge defining a weir that is capable of being raised or lowered for varying the depth of the weir in relation to the surface of the body of water. Each module also includes a pump for removing water and pollutants collected in the receptacle and discharging them into a suitable storage area such as settling tanks or the like on the barge or other vessel.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 164 words
A skimmer module adapted to be disposed adjacent the surface of a body of water having floating pollutants therein and comprising a substantially rectangular container having an open top and open front defined by a bottom wall, two side walls and a rear wall, an upwardly inclined plate having one edge connected by means of hinges to the front edge of the bottom wall of the container, said plate having two oppositely disposed triangular side walls extending upwardly therefrom and covering, partly and with a tight fit, the two side walls of the container, said plate having a sharp and slanting front edge to define a cutting weir, said triangular walls having inclined top edges joining with the ends of the front edge of the plate, means to pivot the plate about the hinges for raising and lowering the cutting weir in relation to the surface of the water, and pump means mounted in the bottom of the container, and discharge conduits connected thereto.
Claim 2
Dependent Claim 164 words
A skimmer module adapted to be disposed adjacent the surface of a body of water having floating pollutants therein and comprising a substantially rectangular container having an open top and open front defined by a bottom wall, two side walls and a rear wall, an upwardly inclined plate having one edge connected by means of hinges to the front edge of the bottom wall of the container, said plate having two oppositely disposed triangular side walls extending upwardly therefrom and covering, partly and with a tight fit, the two side walls of the container, said plate having a sharp and slanting front edge to define a cutting weir, said triangular walls having inclined top edges joining with the ends of the front edge of the plate, means to pivot the plate about the hinges for raising and lowering the cutting weir in relation to the surface of the water, and pump means mounted in the bottom of the container, and discharge conduits connected thereto.
Claim 3
Dependent Claim 37 words
The module of claim 1 wherein the means to raise and lower the cutting weir are two oppositely disposed hydraulic rams each operatively connecting the upper portions of the partly overlapping container side walls and triangular walls.
Claim 4
Dependent Claim 36 words
The module of claim 1 wherein the upper edges of the side walls of the container and the upper edges of the triangular walls are provided with means for laterally connecting two modules which are mirror-identical.
Claim 5
Dependent Claim 30 words
The module of claim 1 wherein the rear wall of the container is provided with means to connect the module to a front portion of a barge or other vessel.
