Abstract
Abstract An attachment for a boat effective when the latter travels in forward direction on a body of water. The attachment absorbs water on the advance of the boat, leads it upwardly through a tank, and discharges it downwardly toward the body of water in the form of a spray. The tank contains a water-purifying substance, and is tall to lend the rise of the water long travel. The tall tank also locates the source of the spray at a high elevation for directing it through a large area of air for the further purification of the emitted water by oxygenation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
131 words
An attachment for a boat movable forwardly on a body of water, comprising a tube under the boat opening with one end forwardly to absorb water from said body during the advance of the boat, an upright tank carried by the boat and receiving the rear end of the tube at the bottom for said water to be received into and rise in the tank, a filling of filtering material in the tank and adapted to divest the water of impurities during its rise in the tank, and an outlet from the top region of the tank trained downwardly with a nozzle to direct a spray of the purified water toward said body, such spray designed to absorb oxygen from the air and further purify the water emitted by the spray.
Claim 2
Dependent Claim
131 words
An attachment for a boat movable forwardly on a body of water, comprising a tube under the boat opening with one end forwardly to absorb water from said body during the advance of the boat, an upright tank carried by the boat and receiving the rear end of the tube at the bottom for said water to be received into and rise in the tank, a filling of filtering material in the tank and adapted to divest the water of impurities during its rise in the tank, and an outlet from the top region of the tank trained downwardly with a nozzle to direct a spray of the purified water toward said body, such spray designed to absorb oxygen from the air and further purify the water emitted by the spray.
Claim 3
Dependent Claim
14 words
The structure of claim 1, said tank attached to the stern of the boat.
Claim 4
Dependent Claim
52 words
The structure of claim 1, the tank being upwardly elongated to lend said rise long travel and position said nozzle high above said body of water, in order that the spray may travel and spread through an extended area for maximum absorption of oxygen from the air above said body of water.
Claim 5
Dependent Claim
33 words
The structure of claim 1, where the boat has an outboard motor at rear center, a pair of the attachments applied to the stern of the boat on opposite sides of said motor.
