Abstract
Abstract A vacuum apparatus for the cleansing of submerged surfaces is provided whereby brush devices are centrally located on opposite sides of a suction element and work with a rib to create a vortex thereby facilitating the cleansing action. The suction element consists of multiple chambers, which are separated by a diaphragm integrally connected to oppositely opening access wings. Variable mounting of wing control arms provide for selective cleaning of large or small debris.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
102 words
A liquid submerged surface vacuum cleaning system, comprising, a housing, a brush element attached to said housing and adapted to separate said housing into first and second compartments, a means integral with said housing for evacuating said first and second compartments of said housing, a wing movably secured to said housing and adapted to move upon passage of said housing through said liquid, a means within said evacuating means for selectively controlling the evacuation of either said first or second compartment, said controlling means attached to said wing and operable upon movement of said wing from a first to a second position.
Claim 2
Dependent Claim
102 words
A liquid submerged surface vacuum cleaning system, comprising, a housing, a brush element attached to said housing and adapted to separate said housing into first and second compartments, a means integral with said housing for evacuating said first and second compartments of said housing, a wing movably secured to said housing and adapted to move upon passage of said housing through said liquid, a means within said evacuating means for selectively controlling the evacuation of either said first or second compartment, said controlling means attached to said wing and operable upon movement of said wing from a first to a second position.
Claim 3
Dependent Claim
18 words
The apparatus of claim 1, wherein movement of said wing to a first position evacuates said first compartment.
Claim 4
Dependent Claim
18 words
The apparatus of claim 1 wherein movement of said wing to a first position evacuates said second compartment.
Claim 5
Dependent Claim
65 words
The apparatus of claim 2 or 3 which includes a second wing moveably secured to said housing and operable with said controlling means upon passage of said housing through said liquid wherein said second wing is in a second position when said wing is in a first position and said second wing is in a first position when said wing is in a second position.
Claim 6
Dependent Claim
40 words
The apparatus of claim 1 which includes a pair of ridges integral with said housing and spaced apart with said brush element therebetween, said ridges adapted to direct liquid flow within said first and second compartments toward said brush element.
Claim 7
Independent Claim
124 words
An apparatus for the cleansing of surfaces submerged under a liquid, the apparatus comprising, a housing having multiple compartments formed therein, a means for evacuating said compartments, said evacuating means integral with said housing, a means for selecting which compartment is to be evacuated, said selecting means disposed within said evacuating means, a brush element integral with said housing, said brush element adapted to compartmentalize said housing, and said brush element further adapted to travel with said housing in contact with said submerged surface to be cleaned, a wing movably secured to said housing and operable with said selecting means, whereby movement of said wing by passage of said housing through said liquid occasions selected evacuation of said housing compartments by said evacuating means.
Claim 8
Independent Claim
124 words
An apparatus for the cleansing of surfaces submerged under a liquid, the apparatus comprising, a housing having multiple compartments formed therein, a means for evacuating said compartments, said evacuating means integral with said housing, a means for selecting which compartment is to be evacuated, said selecting means disposed within said evacuating means, a brush element integral with said housing, said brush element adapted to compartmentalize said housing, and said brush element further adapted to travel with said housing in contact with said submerged surface to be cleaned, a wing movably secured to said housing and operable with said selecting means, whereby movement of said wing by passage of said housing through said liquid occasions selected evacuation of said housing compartments by said evacuating means.
Claim 9
Dependent Claim
21 words
The apparatus of claim 6, which includes a second wing moveably secured to said housing and operable with said selecting means.
Claim 10
Dependent Claim
37 words
The apparatus of claim 6 which includes multiple ridges at least one of which is integral with each compartment within said housing, said ridges adapted to direct flow of fluid within said compartments toward said brush element.
Claim 11
Independent Claim
164 words
An apparatus for the cleansing of surfaces submerged within a liquid, the apparatus comprising, a housing adapted to traverse the surface to be cleansed, a scraping element integral with said housing and adapted to separate said housing into first and second compartments, said scraping element in contact with said surface to be cleansed, a means for evacuating said compartments, said evacuating means integral with said housing, a pair of wings pivotably secured to said housing, each one of said wings pivotably secured on an opposite side of said housing, a diaphragm means operable within said evacuating means for selectively evacuating the compartments of said housing, said diaphragm means operable upon pivotal movement of said pair of wings, a rib means integral with each of said compartments for directing the flow of liquid toward said scraping element, whereby movement of said housing occasions rotation of said wings and movement of said diaphragm means to evacuate only one of said compartments during movement of said housing.
Claim 12
Independent Claim
164 words
An apparatus for the cleansing of surfaces submerged within a liquid, the apparatus comprising, a housing adapted to traverse the surface to be cleansed, a scraping element integral with said housing and adapted to separate said housing into first and second compartments, said scraping element in contact with said surface to be cleansed, a means for evacuating said compartments, said evacuating means integral with said housing, a pair of wings pivotably secured to said housing, each one of said wings pivotably secured on an opposite side of said housing, a diaphragm means operable within said evacuating means for selectively evacuating the compartments of said housing, said diaphragm means operable upon pivotal movement of said pair of wings, a rib means integral with each of said compartments for directing the flow of liquid toward said scraping element, whereby movement of said housing occasions rotation of said wings and movement of said diaphragm means to evacuate only one of said compartments during movement of said housing.
Claim 13
Dependent Claim
20 words
The apparatus of claim 9 which includes a means for alternating the compartment being evacuated upon pivoting of said wings.
