Abstract
Abstract A device to direct floating oil into a recovery mechanism comprising a flexible rubber hose having attached floats positioned at spaced intervals. Water jets are operatively connected to the hose between the floats, and counterweights are added to uniformly balance the unit. A water pump provides water to the hose which is sprayed by the jets against the oil slick, forcing it to the recovery mechanism.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
87 words
A device to direct floating oil into a recovery mechanism comprising: a flexible hose; floats attached to said hose at spaced intervals; water jets of the fan jet variety operatively connected to said flexible hose between said floats; counterweights mounted aft of said water jets and adapted to uniformly balance the entire device; and a water pump to provide low pressure, high volume water to the flexiBle hose, said water being sprayed through said jets and against the floating oil, forcing the same to a recovery mechanism.
Claim 2
Independent Claim
87 words
A device to direct floating oil into a recovery mechanism comprising: a flexible hose; floats attached to said hose at spaced intervals; water jets of the fan jet variety operatively connected to said flexible hose between said floats; counterweights mounted aft of said water jets and adapted to uniformly balance the entire device; and a water pump to provide low pressure, high volume water to the flexiBle hose, said water being sprayed through said jets and against the floating oil, forcing the same to a recovery mechanism.
Claim 3
Dependent Claim
35 words
The device of claim 1 wherein: a torque stabilizer is mounted on the bottom of said water jets to prevent excessive torque motion of said jets during operation, thereby keeping the jet in proper position.
Claim 4
Dependent Claim
21 words
The device of claim 1 wherein said flexible hose is fabricated of flexible rubber having a 1 1/2 inches inside diameter.
Claim 5
Dependent Claim
13 words
The device of claim 1 wherein the floats are fabricated of closed-cell polyurethane.
Claim 6
Dependent Claim
15 words
The device of claim 1 wherein said water pump is attached to said recovery mechanism.
Claim 7
Dependent Claim
65 words
The device of claim 1 wherein a pair of tension lines are attached at one end to said flexible hose at widely spaced intervals through swivel joints and at the opposite end to a winch; thus upon operation of the winch, said tension lines draw the hose, jets and other structure toward the oil recovery mechanism which forces the floating oil into the recovery mechanism.
