Claim 1
Independent Claim
112 words
A plumbing sealing device, comprising: oppositely positioned first and second separate sections, each of said sections having a notch defined substantially in the center thereof, each of said sections having a face portion, a downwardly extending wall integral with each of said face portions, said walls disposed at an angle to said face portions, a sleeve integral with each of said face portions of said sections, a flange extending outwardly from the face portion of each of said sections, a securing means integral with each of said flanges, whereby said flanges are adapted to fit within said sleeves defined in said face portions to occasion connection of said first and second sections.
Claim 2
Dependent Claim
112 words
A plumbing sealing device, comprising: oppositely positioned first and second separate sections, each of said sections having a notch defined substantially in the center thereof, each of said sections having a face portion, a downwardly extending wall integral with each of said face portions, said walls disposed at an angle to said face portions, a sleeve integral with each of said face portions of said sections, a flange extending outwardly from the face portion of each of said sections, a securing means integral with each of said flanges, whereby said flanges are adapted to fit within said sleeves defined in said face portions to occasion connection of said first and second sections.
Claim 3
Dependent Claim
166 words
A plumbing sealing device for use in sealing the walls of a room through which plumbing fixtures are disposed, said device comprising, a first semicircular section having a face portion, a sleeve defined within said face portion, a wall integral with said face portion and extending downwardly from said face portion at an angle thereto, a notch defined within said face portion, a second wall integral with said face portion and extending downwardly from said face portion along the periphery of said notch, a flange extending outwardly from said face portion and a securing means integral with said flange, a second substantially identical semicircular section, whereby rotation of said second semicircular section 180 degrees from said first semicircular section permits adjuxtaposition of said first and second semicircular sections to form a substantially disc-shaped object upon passage of said flange of said first section through said sleeve of said second section and passage of said flange of said second section through said sleeve of said first section.
