Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 131 words
A portable tacking unit comprising: a tacking head including a cylindrical brush, a housing adapted to rotatably support the brush such that a major portion of the circumference of the brush is exposed and a minor portion thereof is surrounded by the housing, said housing further including an exhaust port disposed proximate the minor portion of the brush and adapted to withdraw ambient air therefrom, said tacking head being relatively lightweight and of a size configured for hand-held operation by a single worker; a central suction unit adapted to provide a flow of air at pressures less than atmospheric; and a flexible conduit operatively connecting said exhaust port to the suction unit such that a low pressure flow of air is established from said exhaust port to said central suction unit.
Claim 2
Dependent Claim 131 words
A portable tacking unit comprising: a tacking head including a cylindrical brush, a housing adapted to rotatably support the brush such that a major portion of the circumference of the brush is exposed and a minor portion thereof is surrounded by the housing, said housing further including an exhaust port disposed proximate the minor portion of the brush and adapted to withdraw ambient air therefrom, said tacking head being relatively lightweight and of a size configured for hand-held operation by a single worker; a central suction unit adapted to provide a flow of air at pressures less than atmospheric; and a flexible conduit operatively connecting said exhaust port to the suction unit such that a low pressure flow of air is established from said exhaust port to said central suction unit.
Claim 3
Dependent Claim 25 words
An apparatus as in claim 1, wherein said brush is a cylindrical brush comprising a rigid inner core having a plurality of feathers affixed thereto.
Claim 4
Dependent Claim 12 words
An apparatus as in claim 2, wherein said feathers are ratite feathers.
Claim 5
Dependent Claim 21 words
An apparatus as in claim 1, wherein said brush is approximately 5-72 inches in length and approximately 5-24 inches in width.
Claim 6
Dependent Claim 16 words
An apparatus as in claim 1, wherein said housing includes drive means for rotating the brush.
Claim 7
Dependent Claim 14 words
An apparatus as in claim 5, wherein said drive means includes an electric motor.
Claim 8
Dependent Claim 14 words
An apparatus as in claim 5, wherein said drive means includes a flexible shaft.
Claim 9
Dependent Claim 23 words
An apparatus as in claim 7, wherein said flexible shaft is an elongated flexible shaft in operative communication with the central suction unit.
Claim 10
Dependent Claim 60 words
An apparatus as in claim 1, wherein said brush is adapted to generate a static electrical charge in use so as to attract and retain dust particles thereupon and said housing further includes an ion generator associated therewith and adapted to discharge the static electrical charge from the brush so as to facilitate the release of dust particles attracted thereto.
Claim 11
Dependent Claim 22 words
An apparatus as in claim 1, wherein the major portion of the circumference of the brush corresponds to at least 270° thereof.
Claim 12
Dependent Claim 34 words
An apparatus as in claim 1, wherein said central suction unit is adapted to operate in cooperation with the exhaust port and the flexible conduit so as to withdraw dust particles from the brush.
Claim 13
Dependent Claim 19 words
An apparatus as in claim 11 wherein said central suction unit is further adapted to collect the dust particles.
Claim 14
Dependent Claim 13 words
An apparatus as in claim 1, wherein said brush is a bristle brush.
Claim 15
Dependent Claim 139 words
A portable tacking unit comprising: a tacking head including a cylindrical feather brush approximately 5-72 inches in length and 5-24 inches in width; a housing adapted to rotatably support the brush such that a major portion of the brush is exposed and a minor portion thereof is surrounded by the housing, said housing further including an exhaust port disposed proximate the minor portion of the brush and adapted to withdraw ambient air therefrom, said tacking heat being relatively lightweight and of a size configured for hand-held operation by a single worker; a central suction unit adapted to provide a flow of air at pressures less than atmospheric; and a flexible conduit operatively connecting said exhaust port to the suction unit such that a low pressure flow of air is established from said exhaust port to said central suction unit.
Claim 16
Dependent Claim 139 words
A portable tacking unit comprising: a tacking head including a cylindrical feather brush approximately 5-72 inches in length and 5-24 inches in width; a housing adapted to rotatably support the brush such that a major portion of the brush is exposed and a minor portion thereof is surrounded by the housing, said housing further including an exhaust port disposed proximate the minor portion of the brush and adapted to withdraw ambient air therefrom, said tacking heat being relatively lightweight and of a size configured for hand-held operation by a single worker; a central suction unit adapted to provide a flow of air at pressures less than atmospheric; and a flexible conduit operatively connecting said exhaust port to the suction unit such that a low pressure flow of air is established from said exhaust port to said central suction unit.
Claim 17
Dependent Claim 129 words
A portable tacking unit comprising: a plurality of tacking heads, each head including a cylindrical brush, a housing adapted to rotatably support the brush such that a first portion of the brush is exposed and a second portion thereof is surrounded by the housing, said housing further including an exhaust port disposed proximate the second portion of the brush and adapted to withdraw ambient air therefrom; a central suction unit adapted to provide a flow of air at pressures less than atmospheric; and a plurality of flexible conduits, each conduit associated with one of said plurality of tacking heads and operatively connecting said exhaust port thereof to the suction unit so that a low pressure flow of air is established from the exhaust port to the central suction unit.
Claim 18
Dependent Claim 129 words
A portable tacking unit comprising: a plurality of tacking heads, each head including a cylindrical brush, a housing adapted to rotatably support the brush such that a first portion of the brush is exposed and a second portion thereof is surrounded by the housing, said housing further including an exhaust port disposed proximate the second portion of the brush and adapted to withdraw ambient air therefrom; a central suction unit adapted to provide a flow of air at pressures less than atmospheric; and a plurality of flexible conduits, each conduit associated with one of said plurality of tacking heads and operatively connecting said exhaust port thereof to the suction unit so that a low pressure flow of air is established from the exhaust port to the central suction unit.
