Claim 7

An oil separator according to claim 1 including means mounting said brush for adjustment toward and away from the body of water containing the oil spill.

Claim 8

An oil separator according to claim 1 including means for delivering the water discharged from said outlet of said housing of said water driven turbine back into the body of water containing the oil spill.

Claim 9

An oil separator for use in cleaning up oil spills from a body of water containing the same comprising: means providing a housing having an opening overlying the body of water containing the oil spill, a brush rotatably mounted in said housing to extend through said opening therein and for movement through a circular path including a first portion wherein said brush dips into and moves through the oil/water mixture near the surface of said body of water to pick up oil adhering to the brush surfaces and a second portion located above the surface of said body of water, means for driving said brush, means for wiping oil from said brush surfaces thereof as said brush moves through said second portion of said circular path to thereby separate the oil, means for collecting the wiped off oil in a container, means for pumping the collected oil from said container thereof to a surface location, said oil pumping means including a pump and means for driving said pump, said brush driving means and said pump driving means including a water driven turbine constructed and arranged to cause rotation of said brush and operation of said pump, float means constructed and arranged to support the oil separator near the surface of the body of the water containing the oil spill so that said brush is positioned to move through said circular path, and a fan mounted in said housing for creating a vacuum in the interior of said housing.

Claim 10

An oil separator for use in cleaning up oil spills from a body of water containing the same comprising: means providing a housing having an opening overlying the body of water containing the oil spill, a brush rotatably mounted in said housing to extend through said opening therein and for movement through a circular path including a first portion wherein said brush dips into and moves through the oil/water mixture near the surface of said body of water to pick up oil adhering to the brush surfaces and a second portion located above the surface of said body of water, means for driving said brush, means for wiping oil from said brush surfaces thereof as said brush moves through said second portion of said circular path to thereby separate the oil, means for collecting the wiped off oil in a container, means for pumping the collected oil from said container thereof to a surface location, said oil pumping means including a pump and means for driving said pump, said brush driving means and said pump driving means including a water driven turbine constructed and arranged to cause rotation of said brush and operation of said pump, float means constructed and arranged to support the oil separator near the surface of the body of the water containing the oil spill so that said brush is positioned to move through said circular path, and a fan mounted in said housing for creating a vacuum in the interior of said housing.

Claim 11

An oil separator according to claim 8 wherein said housing is constructed and arranged to define inlet openings spaced from the surface of said body of water to define a passage whereby high velocity air rushes therepast into the interior of said housing.

Claim 12

An oil separator according to claim 9 including a plurality of skimmer screens, one of said screens being mounted on the downstream end of said fan for trapping oil contained in the fluid driven by said fan, the other of said screens being mounted on the inlet side of said fan.

Claim 13

An oil separator according to claim 8 including means for driving said fan from said water driven turbine.

Claim 14

An oil separator for use in cleaning up oil spills from a body of water containing the same comprising: means providing a housing having an opening overlying the body of water containing the oil spill, a brush rotatably mounted in said housing to extend through said opening therein and for movement through a circular path including a first position wherein said brush dips into and moves through the oil/water mixture near the surface of said body of water to pick up oil adhering to the brush surfaces and a second portion located above the surface of said body of water, means for driving said brush, means for wiping oil from said brush surfaces thereof as said brush moves through said second portion of said circular path to thereby separate the oil, means for collecting the wiped off oil in a container, means for pumping the collected oil from said container thereof to a surface location, said oil pumping means including a pump and means for driving said pump, said brush driving means and said pump driving means including a water driven turbine constructed and arranged to cause rotation of said brush and operation of said pump, said water driven turbine including a housing and a bladed impeller mounted for rotation within said housing, said housing having an inlet and an outlet for directing water into and out of said housing for driving said impeller, float means constructed and arranged to support the oil separator near the surface of the body of water containing the oil spill so that said brush is positioned to move through said circular path, a main pump having a suction and a discharge and lines for connecting the discharge of said main pump to the inlet of said water driven turbine for driving the same, means for supplying water to the suction of said main pump from a water supply, and means for delivering water from the outlet of said housing of said water driven turbine into said body of water containing the oil spill.
