Abstract
Abstract A drainage system preferably to eliminate wet and damp basements which is formed from an inexpensive, easily assembled pair of sheet metal members. A strip of waterproof sealing material is placed on the basement floor extending along the basement wall with one of the sheet metal members having an L-shaped configuration being mounted on top of the strip of sealing material and secured to the floor by fasteners. An upstanding leg flange of the L-shaped member is spaced from the wall and forms a drainage channel with the wall and floor. The second sheet metal member is removably mounted on the top edge of the upstanding leg member and extends generally horizontally across the top of the drainage channel and engages the wall to form a removable top closure for the channel. A plurality of holes are drilled through the basement wall adjacent the basement floor to permit outside water to readily flow through the wall and into the drainage channel. A plurality of air passage ducts may be mounted on the basement wall and communicate with the drainage channel. A blower circulates air from within the basement through the air ducts and drainage channel to the outside air to remove moisture from the basement and drainage channel.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
132 words
A drainage system for use in an area having at least a wall and adjoining floor including; a. a generally L-shaped sheet metal member having a base flange and an upstanding leg flange having orifice means therein; said member being adapted to be mounted on the floor adjacent the wall of the area; b. sealing means adapted to seal the base flange with respect to the floor; c. fastening means adapted to secure the base flange to the floor, with the upstanding leg flange being spaced from the wall to form a drainage channel with said wall and floor; and d. top closure means removably mounted on the upstanding leg flange and extending across the drainage channel and engageable with the wall to form a removable top closure for the drainage channel.
Claim 2
Dependent Claim
132 words
A drainage system for use in an area having at least a wall and adjoining floor including; a. a generally L-shaped sheet metal member having a base flange and an upstanding leg flange having orifice means therein; said member being adapted to be mounted on the floor adjacent the wall of the area; b. sealing means adapted to seal the base flange with respect to the floor; c. fastening means adapted to secure the base flange to the floor, with the upstanding leg flange being spaced from the wall to form a drainage channel with said wall and floor; and d. top closure means removably mounted on the upstanding leg flange and extending across the drainage channel and engageable with the wall to form a removable top closure for the drainage channel.
Claim 3
Dependent Claim
52 words
The system defined in claim 1 in which spaced input and exhaust air passage means communicate with the drainage channel; in which blower means communicates with the input air passage means and circulates air through the drainage channel and exhaust air passage means to assist in evaporating moisture within the drainage channel.
Claim 4
Dependent Claim
56 words
The system defined in claim 2 in which the air passage means each includes a sheet metal duct adapted to extend vertically along the wall upwardly from the drainage channel; and in which each of said ducts comprises a pair of L-shaped sheet metal members joined in overlapping relationship to provide the ducts with U-shaped configurations.
Claim 5
Dependent Claim
32 words
The system defined in claim 3 in which the L-shaped sheet metal members of the air passage means ducts are identical to the L-shaped sheet metal member which form the drainage channel.
Claim 6
Dependent Claim
38 words
The system defined in claim 3 in which the top closure means of the drainage channel is formed with opening means; and in which the air passage means ducts communicate with the drainage channel through said opening means.
Claim 7
Dependent Claim
85 words
The system defined in claim 1 in which the upstanding leg flange terminates in a reversely bent top edge; in which the closure means includes a generally planar sheet metal strip terminating in first and second side edges, with said second edge being formed with inverted U-shaped flange means extending upwardly from the planar strip; and in which the upstanding leg flange top edge is slip-fitted within the closure means U-shaped flange means to removably mount the closure means on the L-shaped sheet metal member.
Claim 8
Dependent Claim
39 words
The system defined in claim 6 in which the planar strip slopes upwardly from the inverted U-shaped flange means toward the wall and forms an exterior secondary drain area at the junction of said planar strip and flange means.
Claim 9
Dependent Claim
48 words
The system defined in claim 1 in which the upstanding leg flange forms an acute angle with the base flange in unassembled condition; and in which said leg flange is generally perpendicular with the base flange in assembled condition and biases the top closure means towards the wall.
Claim 10
Dependent Claim
36 words
The system defined in claim 1 in which the top closure means has a wall engaging edge; and in which sealing means is mounted on said edge to provide a seal when engaged with a wall.
Claim 11
Dependent Claim
167 words
A basement drainage system in combination with a basement wall and floor including: a. an elongated generally L-shaped sheet metal member having a base flange and an upstanding leg flange; b. a strip of sealing material extending along the wall and overlying the basement floor adjacent said wall; c. fastening means securing the base flange of the L-shaped member to the floor with the strip of sealing material being interposed between the floor and said base flange providing a generally watertight seal therebetween; d. the upstanding leg flange being spaced a predetermined distance from the wall and forming a drainage channel with said wall and base flange; e. a sheet metal top closure member removably mounted on the leg flange and extending across the drainage channel and engaging the wall to form a removable top closure for the drainage channel; and f. opening means formed in the wall communicating with the drainage channel whereby seepage water may flow through said opening means and into the drainage channel.
Claim 12
Dependent Claim
167 words
A basement drainage system in combination with a basement wall and floor including: a. an elongated generally L-shaped sheet metal member having a base flange and an upstanding leg flange; b. a strip of sealing material extending along the wall and overlying the basement floor adjacent said wall; c. fastening means securing the base flange of the L-shaped member to the floor with the strip of sealing material being interposed between the floor and said base flange providing a generally watertight seal therebetween; d. the upstanding leg flange being spaced a predetermined distance from the wall and forming a drainage channel with said wall and base flange; e. a sheet metal top closure member removably mounted on the leg flange and extending across the drainage channel and engaging the wall to form a removable top closure for the drainage channel; and f. opening means formed in the wall communicating with the drainage channel whereby seepage water may flow through said opening means and into the drainage channel.
Claim 13
Dependent Claim
92 words
The system defined in claim 10 in which a plurality of duct means are mounted on the wall and communicate with the drainage channel; in which blower means is operatively connected to one of the duct means and draws air from within the basement through said one duct means, through the channel means and through a second duct means; and in which an exhaust opening is formed in the wall and communicates with said second duct means for exhausting the air from the second duct means through the wall to the outside.
