Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
182 words
In combination, an upstanding tubular flue line section, means in said section operative to spray cleaning liquid on the internal surfaces of said section about substantially the entire inner periphery of at least one upper zone of said upstanding section, means in a lower zone of said section operative to collect and drain away liquid flowing downwardly along the inner surfaces of said lower zone throughout substantially the entire inner periphery of said lower zone, the last-mentioned means comprising gas barrier means mounted in said lower zone shiftable between an inoperative position allowing the passage of flue gases there past and an operative position defining a transverse barrier in said lower zone to the upward passage of flue gases and the downward passage of liquids therepast, a drain opening formed through one wall portion of the lower zone of said flue section, said transverse barrier, when in the operative position, also including means operative to collect any liquids flowing downwardly along the adjacent inner surface portions of said section and to divert the collected liquids to said drain opening for discharge therethrough.
Claim 2

Claim 3
Dependent Claim
81 words
In combination, an upstanding tubular flue line section, means in said section operative to spray cleaning liquid on the internal surfaces of said section, means in a lower portion of said section operative to collect and drain away liquid flowing downwardly along said inner surfaces toward the second mentioned means, said means in said lower portion comprising flap valve means shiftable between open and closed position closing the lower end of said upstanding section and gravity urged toward said closed position.
Claim 4
Dependent Claim
81 words
In combination, an upstanding tubular flue line section, means in said section operative to spray cleaning liquid on the internal surfaces of said section, means in a lower portion of said section operative to collect and drain away liquid flowing downwardly along said inner surfaces toward the second mentioned means, said means in said lower portion comprising flap valve means shiftable between open and closed position closing the lower end of said upstanding section and gravity urged toward said closed position.
Claim 5
Dependent Claim
108 words
The combination of claim 2 wherein said flap valve means includes an annular flange disposed in said lower portion inclined at least slightly relative to a horizontal plane so as to have one peripheral portion lower than all other peripheral portions of said flange, a pair of semicircular wing members pivotally supported along their base marginal edge portions for oscillation about an axes extending generally diametrically of said annular flange and including generally semicircular edge portions which overlie said flange when said wing members are generally horizontally disposed, said wing members being swingable from substantially horizontally disposed positions toward upstanding but at least slightly upwardly divergent open position.
Claim 6
Dependent Claim
28 words
The combination of claim 3 wherein said flap valve means includes seal means disposed between the semicircular marginal edge portions of said wing members and said annular flange.
Claim 7
Dependent Claim
136 words
The combination of claim 2 wherein said flap valve means includes an annular flange disposed in said lower portion inclined at least slightly relative to a horizontal plane so as to have one peripheral portion lower than all other peripheral portions of said flange, a pair of semicircular wing members pivotally supported along their base marginal edge portions for oscillation about an axes extending generally diametrically of said annular flange and including generally semicircular edge portions which overlie said flange when said wing members are generally horizontally disposed, said wing members being swingable from substantially horizontally disposed positions toward upstanding but at least slightly upwardly divergent open position, and a tubular drain fitting opening through said lower portion of said flue line in general horizontal registry with and adjacent the lower portion of said annular flange.
Claim 8
Dependent Claim
55 words
The combination of claim 5 wherein said upstanding tubular flue line section includes a blower assembly for pumping air through said flow line section, said blower assembly being of sufficient power to cause said wing members to automatically swing from the closed positions thereof to the open positions thereof upon operation of said blower means.
Claim 9
Dependent Claim
145 words
In combination, an upstanding tubular flue line section, means in said section operative to spray cleaning liquid on the internal surfaces of said section, means in a lower portion of said section operative to collect and drain away liquid flowing downwardly along said inner surfaces toward the second mentioned means, said means operative to spray cleaning liquid on the internal surfaces of said section comprising an upstanding tubular manifold line journaled for rotation in said flue line section whereby the entire inner surfaces of said tubular member may be cleaned, means supplying the interior of said manifold line with cleaning liquid under pressure, said manifold line including outlet nozzles communicating with the interior of said manifold and opening outwardly therefrom, said nozzles being spaced longitudinally of said manifold line and positioned therealong for spraying at least the adjacent inner surface portion of said flue line.
