Abstract
Abstract An elongated flexible strip incorporating a longitudinally extending central tube provided with egress openings is arranged to be wrapped about the hull portion of a boat adjacent its bow. A chemical is fed into the central tube and passes out in controlled quantities from the egress openings to thereby form with water passing by the hull a diluted solution which then passes down the length of the hull and thereby reduces the friction of the boat hull when passing through water.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
227 words
An apparatus for dispensing a diluted solution of water and chemical adjacent to the bow of a boat to thereby reduce the friction of the boat hull when passing through water, comprising, in combination: a. an elongated strip of flexible material having a thickened longitudinal central portion tapering to thinner dimensions towards the longitudinal edges thereof, the back surface of said strip being substantially flat; b. a bore passing longitudinally through said strip, a longitudinal wall portion of said bore including lateral egress openings exposed along the front surface of said strip; c. a plurality of curved passage means, each of said means terminating in entrance and exit openings along the front surface of said strip said lateral egress openings being adjacent to the entrance openings of said plurality of curved passage means respectively, whereby a desired length of said strip may be cut and wrapped about the underside of the bow portion of a boat hull with the back surface of said strip engaging said hull and said entrance openings facing forwardly so that a chemical fed into said bore at each end will flow from said egress openings and mix with water passing into said entrance openings of said passage means to form said diluted solution, said solution exiting from said exit openings to flow along the major portions of the hull of said boat.
Claim 2
Independent Claim
227 words
An apparatus for dispensing a diluted solution of water and chemical adjacent to the bow of a boat to thereby reduce the friction of the boat hull when passing through water, comprising, in combination: a. an elongated strip of flexible material having a thickened longitudinal central portion tapering to thinner dimensions towards the longitudinal edges thereof, the back surface of said strip being substantially flat; b. a bore passing longitudinally through said strip, a longitudinal wall portion of said bore including lateral egress openings exposed along the front surface of said strip; c. a plurality of curved passage means, each of said means terminating in entrance and exit openings along the front surface of said strip said lateral egress openings being adjacent to the entrance openings of said plurality of curved passage means respectively, whereby a desired length of said strip may be cut and wrapped about the underside of the bow portion of a boat hull with the back surface of said strip engaging said hull and said entrance openings facing forwardly so that a chemical fed into said bore at each end will flow from said egress openings and mix with water passing into said entrance openings of said passage means to form said diluted solution, said solution exiting from said exit openings to flow along the major portions of the hull of said boat.
Claim 3
Dependent Claim
68 words
An apparatus according to claim 1, including chemical storage tanks for securement on either side of said boat above the ends of said strip; conduit means for connecting said tanks to the ends of said bore; and control valves in said conduit means for controlling the rate of chemical flow into said bore whereby the rate of flow of said chemical from said egress holes may be controlled.
Claim 4
Dependent Claim
69 words
An apparatus according to claim 1, in which said bore is defined by a tube imbedded within said strip, each of said curved passage means being in the form of a spiral circumferentially extending substantially 360* about said tube, said entrance and exit openings lying in a plane normal to the back surface of said strip and spaced longitudinally by an amount defined by the pitch of said spiral.
Claim 5
Dependent Claim
42 words
An apparatus according to claim 1, in which each of said curved passage means extends over an arc greater than 180* , the sidewalls initially diverging towards the central portions of the passage and then converging to define a narrower exit opening.
