Abstract

Abstract ABSTRACT OF THE DISCLOSURE The invention relates to a device for picking up oil from water and from the surface of water, the device being installed to a water craft and comprising at least one collecting means passing around rolls and being installed obliquely, there being at the upper end of the collecting means devices for removing the oil collected by the collecting means and for directing it into a tank in the water craft. The object is especially to eliminate the disadvantages of previously known devices of the mat type that, when the craft moves, the mat tends to direct water and, along with it, also oil to the sides, past the mat. In accordance with the invention the device comprises a number of parallel loop-like collecting means, each of which is made up of pieces provided with upwards and side-wards extending bristles and fixed to the chain, the side-wards-directed bristles extending sufficiently far to come into contact with each other, but allowing water to flow without hindrance through the device.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 161 words
A device for picking up oil from water and from the surface of water, the device being adapted to be installed on a water craft and comprising: a plurality of continuous loop collecting means, the loops being arranged parallel to each other and adapted to be disposed in a water craft about upper and lower roller means disposed on parallel, spaced axes to extend obliquely downwards with the lower roller being in the water and the upper roller above the water level; each of said collecting means comprising a chain and successive body means fixed on said chain forming a successive line thereon and provided with bristles that extend in the longitudinal direction of the chain, outwardly and to both sides thereof in such manner that the bristles of adjacent collecting means contact each other while allowing the flow of water between said respective collecting means; and means provided adjacent the upper ends of said collecting means for removing oil therefrom.
Claim 2
Independent Claim 161 words
A device for picking up oil from water and from the surface of water, the device being adapted to be installed on a water craft and comprising: a plurality of continuous loop collecting means, the loops being arranged parallel to each other and adapted to be disposed in a water craft about upper and lower roller means disposed on parallel, spaced axes to extend obliquely downwards with the lower roller being in the water and the upper roller above the water level; each of said collecting means comprising a chain and successive body means fixed on said chain forming a successive line thereon and provided with bristles that extend in the longitudinal direction of the chain, outwardly and to both sides thereof in such manner that the bristles of adjacent collecting means contact each other while allowing the flow of water between said respective collecting means; and means provided adjacent the upper ends of said collecting means for removing oil therefrom.
Claim 3
Dependent Claim 37 words
A device according to claim 1, wherein the space between said successive bristled body means in the lateral direction, not including the bristles themselves, is at least equal to the width of a body carrying said bristles.
Claim 4
Dependent Claim 55 words
A device according to claim 1 or claim 2, wherein the body of said bristled means has a cross section having substantially the shape of an inverted U, said chain being disposed to pass between the branches of the U and being secured thereto by means of bolts or the like, passing through said chain.
