Abstract
Abstract A plurality of elongated drainage members connected in end to end fashion. The drainage members are located about the periphery of a basement floor, upon the floor and adjacent the basement walls. Each drainage member has a base and a wall connected to the base and spaced apart from the basement wall. A sealant member connects the bases to the basement floor. A drain channel is attached to one drainage member, whereby water collected by the drainage members is directed to an area drain in the basement. A flush assembly is attached to a drainage member half-way about the periphery of the basement floor from the drain channel.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
225 words
A drainage structure for use in the basement of a building, comprising: a plurality of elongated drainage members connected in end to end fashion and located about the periphery of the basement floor adjacent the basement walls, each of said drainage members having a base member and a wall member, said base member being above and connected to the basement floor and having inner and outer edges, said outer edge being adjacent the basement wall, said wall member being attached at said inner edge of said base and upstanding therefrom in spaced relation to the basement wall; and sealant means interconnecting said outer edge of said base with the basement wall, and interconnecting said base with the basement floor, whereby water condensing on the basement walls or leaking therethrough is caught and carried away from the basement walls at a level above the basement floor, said sealant means having a variable thickness between said base members and the basement floor, sad sealant means having a place of maximum thickness and a place of minimum thickness and having a decreasing thickness from said place of maximum thickness to said place of minimum thickness, said sealant means supporting said drainage members at an angle to the floor, whereby water is made to flow through said drainage members to a point directly over said place of minimum thickness.
Claim 2
Dependent Claim
225 words
A drainage structure for use in the basement of a building, comprising: a plurality of elongated drainage members connected in end to end fashion and located about the periphery of the basement floor adjacent the basement walls, each of said drainage members having a base member and a wall member, said base member being above and connected to the basement floor and having inner and outer edges, said outer edge being adjacent the basement wall, said wall member being attached at said inner edge of said base and upstanding therefrom in spaced relation to the basement wall; and sealant means interconnecting said outer edge of said base with the basement wall, and interconnecting said base with the basement floor, whereby water condensing on the basement walls or leaking therethrough is caught and carried away from the basement walls at a level above the basement floor, said sealant means having a variable thickness between said base members and the basement floor, sad sealant means having a place of maximum thickness and a place of minimum thickness and having a decreasing thickness from said place of maximum thickness to said place of minimum thickness, said sealant means supporting said drainage members at an angle to the floor, whereby water is made to flow through said drainage members to a point directly over said place of minimum thickness.
Claim 3
Dependent Claim
122 words
A drainage structure as defined in claim 1 and further wherein said drainage members include a drain channel means, said drainage member which is over said place of minimum thickness having an aperture formed in said wall member directly over said place of minimum thickness, said aperture being rectangular in configuration and extending from said base member to the top of said wall member, said channel means having parallel upstanding walls and a flat member, said flat member being connected to the basement floor by said sealant means and passing through said aperture to attachment with said base member, said upstanding walls being attached to opposite sides of said flat member and to said wall member on opposite sides of said aperture.
Claim 4
Dependent Claim
134 words
A drainage structure as defined in claim 2 and further wherein said drainage members include a flushing means for directing fluids in two, opposite directions, said drainage member which is over said place of maximum thickness having an opening formed in said wall member directly over said place of maximum thickness, said place of maximum thickness being located half-way around the periphery of the basement wall from said place of minimum thickness, said flushing means including a pipe member projecting through said opening and a pipe tee affixed to said pipe member and disposed between said wall member and the basement wall, whereby water may be introduced and directed in opposite directions from said place of maximum, thickness along said drainage members toward said place of minimum thickness to positively clean said drainage members.
