Abstract
Abstract The present invention involves a flexible annular member passing through a wall opening. The flexible annular member is positioned about a conduit passing through the wall opening to enable the conduit to pass through the wall at an angle up to and even greater than 30°. Another embodiment of the present invention comprises a flange type riser and base connection involving the location of the entire sealing assembly within a chamber base/riser section.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
122 words
A sump assembly comprising: a hollow base having a bottom wall, an upstanding side wall and a circumferentially extending radially inwardly directed flange extending from the upper edge of the base; an elongated generally tubular riser section having a circumferentially extending radially inwardly directed flange at its lower terminal edge confronting and overlying the base flange; a cover mounted over the open upper end of the riser; seal means disposed between the confronting faces of the riser and base flanges; and a plurality of circumferentially spaced fasteners for securing the riser flange and base flange together with the seal means interposed therebetween, said fasteners engaging through holes located on a circle generally greater in diameter than that of the tubular riser section.
Claim 2
Dependent Claim
122 words
A sump assembly comprising: a hollow base having a bottom wall, an upstanding side wall and a circumferentially extending radially inwardly directed flange extending from the upper edge of the base; an elongated generally tubular riser section having a circumferentially extending radially inwardly directed flange at its lower terminal edge confronting and overlying the base flange; a cover mounted over the open upper end of the riser; seal means disposed between the confronting faces of the riser and base flanges; and a plurality of circumferentially spaced fasteners for securing the riser flange and base flange together with the seal means interposed therebetween, said fasteners engaging through holes located on a circle generally greater in diameter than that of the tubular riser section.
Claim 3
Dependent Claim
29 words
A sump assembly as claimed in claim 1 wherein said seal means comprises an O-ring having a circumferentially extending sealing surface located radially outboard of the circumferentially spaced fasteners.
Claim 4
Dependent Claim
110 words
A sump assembly comprising: a hollow base having an upstanding side wall and a circumferentially extending radially inwardly directed flange extending from the upper edge of the base; an elongated generally tubular riser section having an outwardly directed step portion at its lower terminal end including at least one generally radial riser flange; seal means disposed between the confronting faces of the riser and base flanges; and a plurality of circumferentially spaced fasteners for securing the riser flange and base flange together with the seal means interposed therebetween whereby said fasteners are disposed interiorly of the riser and base and at least partially within the step portion of the riser.
Claim 5
Dependent Claim
110 words
A sump assembly comprising: a hollow base having an upstanding side wall and a circumferentially extending radially inwardly directed flange extending from the upper edge of the base; an elongated generally tubular riser section having an outwardly directed step portion at its lower terminal end including at least one generally radial riser flange; seal means disposed between the confronting faces of the riser and base flanges; and a plurality of circumferentially spaced fasteners for securing the riser flange and base flange together with the seal means interposed therebetween whereby said fasteners are disposed interiorly of the riser and base and at least partially within the step portion of the riser.
Claim 6
Dependent Claim
123 words
A sump assembly comprising: a hollow base having an upstanding side wall and a circumferentially extending radially inwardly directed flange extending from the upper edge of the base; an elongated generally tubular riser section having an outwardly directed step portion at its lower end including a pair of axially spaced first and second generally radially extending riser flanges connected by an axial wall; seal means disposed between the confronting faces of one of the riser and base flanges; and a plurality of circumferentially spaced fasteners for securing said one riser flange and base flange together with the seal means interposed therebetween whereby said fasteners are disposed interiorly of the riser and base and at least partially within the step portion of the riser.
Claim 7
Dependent Claim
123 words
A sump assembly comprising: a hollow base having an upstanding side wall and a circumferentially extending radially inwardly directed flange extending from the upper edge of the base; an elongated generally tubular riser section having an outwardly directed step portion at its lower end including a pair of axially spaced first and second generally radially extending riser flanges connected by an axial wall; seal means disposed between the confronting faces of one of the riser and base flanges; and a plurality of circumferentially spaced fasteners for securing said one riser flange and base flange together with the seal means interposed therebetween whereby said fasteners are disposed interiorly of the riser and base and at least partially within the step portion of the riser.
Claim 8
Dependent Claim
116 words
