Abstract
Abstract A sleeve adapter (S) for locating a throughpipe (24) in a structural member (18). The sleeve adapter (S) comprises an annular apertured hub (2) having a central axis α, a first annular surface (4) adjacent a first face of the hub (2) sloping inwardly toward the axis, a second annular surface (8) adjacent a second face of the hub (2), and a third annular surface (12) intermediate the first (4) and second (8) surfaces of a smaller diameter than the second annular surface (8). The adapter (S) also comprises a mechanical joint gasket (6) engaging the first annular surface (4) which locates a throughpipe (24) concentric with the central axis, a push-on gasket (10) engaging the second annular surface (8) which locates a sleeve pipe (14) concentric with the central axis, and a pressure means for urging the mechanical joint gasket (6) against the first annular surface (4) and the throughpipe (24). The sleeve adapter (S) optionally comprises a circumferential flange (16) adjacent the second face of the hub (2) which prevents liquid from seeping through the structural member (18).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
132 words
A sleeve adapter for locating a throughpipe in a structural member, comprising: an annular apertured hub having a central axis and a first annular surface adjacent a first face of the hub sloping inwardly toward the axis; a second annular surface adjacent a second face of the hub; a third annular surface intermediate the first and second surfaces and having a diameter smaller than the second annular surface; a mechanical joint gasket engaging the first annular surface for locating a throughpipe concentric with the central axis; a sleeve pipe abutting the third annular surface; a push-on gasket engaging the second annular surface and the sleeve pipe thereby locating, the sleeve pipe concentric with the central axis; and pressure means urging the mechanical joint gasket against said first annular surface and the throughpipe.
Claim 2
Dependent Claim
132 words
A sleeve adapter for locating a throughpipe in a structural member, comprising: an annular apertured hub having a central axis and a first annular surface adjacent a first face of the hub sloping inwardly toward the axis; a second annular surface adjacent a second face of the hub; a third annular surface intermediate the first and second surfaces and having a diameter smaller than the second annular surface; a mechanical joint gasket engaging the first annular surface for locating a throughpipe concentric with the central axis; a sleeve pipe abutting the third annular surface; a push-on gasket engaging the second annular surface and the sleeve pipe thereby locating, the sleeve pipe concentric with the central axis; and pressure means urging the mechanical joint gasket against said first annular surface and the throughpipe.
Claim 3
Dependent Claim
46 words
A sleeve adapter according to claim 1, including studs extending from the first face and engageable selectively with forms used during the pouring of a structural member and with the pressure means for urging the mechanical joint gasket against the first annular surface and the throughpipe.
Claim 4
Dependent Claim
25 words
A sleeve adapter according to claim 1, wherein the pressure means is a gland moveable towards the hub and engageable with the mechanical joint gasket.
Claim 5
Dependent Claim
30 words
A sleeve adapter according to claim 1, wherein the mechanical joint gasket is made of an elastomer thereby allowing the throughpipe to be pivoted for alignment with the central axis.
Claim 6
Dependent Claim
31 words
A sleeve adapter according to claim 1, wherein the hub includes a circumferential flange adjacent the second face of the hub which flange prevents liquid from seeping through the structured member.
Claim 7
Dependent Claim
38 words
A sleeve adapter according to claim 1, wherein the hub includes a circumferential flange adjacent the second face of the hub wherein said flange is integrally cast with the hub and has annuli concentric with the central axis.
Claim 8
Dependent Claim
29 words
A sleeve adapter according to claim 1, wherein the second annular surface of the hub slopes outwardly away from the central axis toward the second face of the hub.
Claim 9
Dependent Claim
20 words
A sleeve adapter according to claim 1, wherein the first face of the hub includes a plurality of tapped bores.
Claim 10
Dependent Claim
14 words
A sleeve adapter according to claim 1, wherein studs extend from the tapped bores.
Claim 11
Dependent Claim
164 words
A sleeve adapter for locating a carrying pipe in a structural, member comprising: an annular apertured hub having a central axis and a first annular surface adjacent a first face of the hub sloping inwardly toward the axis; a second annular surface adjacent a second face of the hub; a third annular surface intermediate the first and second surfaces and having a diameter smaller than the second annular surface, a circumferential flange adjacent the second face of the hub wherein said flange has annuli concentric with the central axis; a mechanical joint gasket engaging the first annular surface for locating a throughpipe concentric with the central axis; a sleeve pipe abutting the third annular surface; a push-on gasket engaging the second annular surface and the sleeve pipe thereby locating, the sleeve pipe concentric with the central axis; and pressure means urging the mechanical joint gasket against said first annular surface and the throughpipe thereby allowing alignment of the throughpipe relative to the central axis.
Claim 12
Dependent Claim
