Abstract
Abstract A flanged fitting comprises a flanged tubular member for positioning in an opening in a floor or roof to form a tubular conduit therethrough. The flange on the fitting may comprise a closet flange, a floor drain flange, or a flat roof flange. Additionally, the flange may be provided with an upstanding tubular member to which a secondary tubular conductor may be attached in the nature of a vent. A sleeve is engaged about the tubular member such as by a clamping member thereon with the upper portion of the sleeve being of a considerably larger diameter and provided with a plurality of circumferentially spaced finger-like sections which are frangible. The flanged fitting may thus be clampingly secured in an opening in a floor or a roof in a desirable location in an opening therein to serve an intended purpose.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
A flanged fitting for installation in openings in floors and roofs comprises a vertically disposed tubular member having an outwardly extending flange inwardly of the upper end thereof, a sleeve slidably disposed on said tubular member below said flange and means on said tubular member below said sleeve for urging said sleeve toward said flange in a clamping-like action, a second tubular member disposed in said first mentioned tubular member above said flange, said secondary tubular member forming a vertical extension, said sleeve having an uppermost area of enlarged diameter incorporating a plurality of circumferentially spaced slots arranged in parallel relation to said tubular member, the portions of said uppermost area of the sleeve between said slots being adapted to be broken away so as to change the configuration of said sleeve.
Claim 2
Dependent Claim
132 words
A flanged fitting for installation in openings in floors and roofs comprises a vertically disposed tubular member having an outwardly extending flange inwardly of the upper end thereof, a sleeve slidably disposed on said tubular member below said flange and means on said tubular member below said sleeve for urging said sleeve toward said flange in a clamping-like action, a second tubular member disposed in said first mentioned tubular member above said flange, said secondary tubular member forming a vertical extension, said sleeve having an uppermost area of enlarged diameter incorporating a plurality of circumferentially spaced slots arranged in parallel relation to said tubular member, the portions of said uppermost area of the sleeve between said slots being adapted to be broken away so as to change the configuration of said sleeve.
Claim 3
Dependent Claim
63 words
The flanged fitting set forth in claim 1 and wherein a continuous thread pattern is formed on said first mentioned tubular member above said flange and a closet flange is engaged on said tubular member, said closet flange having a depending portion, a continuous thread pattern on said depending portion arranged for registry with said thread pattern on said first mentioned tubular member.
Claim 4
Dependent Claim
57 words
The flanged fitting set forth in claim 1 and wherein the means on the fitting below the sleeve for urging the sleeve toward the flange in a clamping-like action comprises a clamping ring having a plurality of circumferentially spaced threaded bores disposed horizontally therein, threaded fasteners engaged in said bores for frictional engagement with said tubular member.
Claim 5
Dependent Claim
94 words
The flanged fitting set forth in claim 1 and wherein the means on the fitting below the sleeve for urging the sleeve toward the flange in a clamping-like action comprises a clamping ring having a plurality of circumferentially spaced threaded bores disposed horizontally therein, threaded fasteners engaged in said bores for frictional engagement with said tubular member, and a plurality of circumferentially spaced vertical bores in said clamping ring and a plurality of secondary fasteners disposed in said vertical bores and movable relative to said clamping ring to exert upward pressure on said sleeve.
Claim 6
Dependent Claim
86 words
The flanged fitting set forth in claim 1 and wherein said means on said fitting below the sleeve for urging the sleeve toward the flange in a clamping-like action comprises the formation of a continuous thread pattern on the exterior of said tubular member and a clamping ring having a continuous thread pattern on its inner surface registrable with the thread pattern on the tubular member, said clamping ring adapted to be rotated to move longitudinally of the tubular member and exert tension on said sleeve.
