Abstract
Abstract A flush-through port device including a fitting having a flared head to be flushly received in a counter-sunk hole in the hull of a boat, a housing having a hollow body screwed onto the fitting to clamp the hull and a tubular coupling member extending from the body at an angle from its central axis, a valve including an interior valve seat formed in the fitting and a valve member carried by a valve stem slidable extending through the body of the housing, a locking cap to be screwed to the housing to lock the valve member in a closed position in sealing engagement with the valve seat, and a sealing member frictionally engaging the valve stem to lock the valve member in an open position out of the path of fluid through the housing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
250 words
A flush-through port device for installation through the hull of a boat comprising: a fitting including first and second ends, a cylindrical wall terminating at said first and second ends having an externally threaded portion at said first end, an inner surface defining an inwardly extending annular valve seat at said second end and an outer tapered head at said second end, said fitting adapted to extend through a hole in the hull of a boat having a countersunk outer portion with a configuration mating with said tapered head being received in said countersunk portion; a housing including a hollow body having an internally threaded inner end adapted to threadably engage said externally threaded first end of said fitting, said body having an outer end opposite said inner end with a central bore therethrough, said bore, said inner end of said body and said second end of said fitting being coaxially aligned; said housing further including a tubular coupling member extending at an angle from the central axis of said housing and communicating with the housing; valve means including a valve stem slidably extending through said bore in said outer end of said body, a valve member mounted on said stem and movable from an open position adjacent said outer end of said body to a closed position adjacent said second end of said fitting; and locking means engaging said valve stem and said outer end of said body for holding said valve member in said closed and open positions.
Claim 2
Dependent Claim
250 words
A flush-through port device for installation through the hull of a boat comprising: a fitting including first and second ends, a cylindrical wall terminating at said first and second ends having an externally threaded portion at said first end, an inner surface defining an inwardly extending annular valve seat at said second end and an outer tapered head at said second end, said fitting adapted to extend through a hole in the hull of a boat having a countersunk outer portion with a configuration mating with said tapered head being received in said countersunk portion; a housing including a hollow body having an internally threaded inner end adapted to threadably engage said externally threaded first end of said fitting, said body having an outer end opposite said inner end with a central bore therethrough, said bore, said inner end of said body and said second end of said fitting being coaxially aligned; said housing further including a tubular coupling member extending at an angle from the central axis of said housing and communicating with the housing; valve means including a valve stem slidably extending through said bore in said outer end of said body, a valve member mounted on said stem and movable from an open position adjacent said outer end of said body to a closed position adjacent said second end of said fitting; and locking means engaging said valve stem and said outer end of said body for holding said valve member in said closed and open positions.
Claim 3
Dependent Claim
37 words
The flush-through port device as recited in claim 1 wherein said locking means includes a cap for engaging said outer end of said body and said valve stem to lock said valvE member in said closed position.
Claim 4
Dependent Claim
36 words
The flush-through port device as recited in claim 1 wherein said locking means includes a sealing member supported by said body and frictionally engaging said valve stem to lock said valve member in said open position.
Claim 5
Dependent Claim
36 words
The flush-through port device as recited in claim 2 wherein said locking means includes a sealing member supported by said body and frictionally engaging said valve stem to lock said valve member in said open position.
Claim 6
Dependent Claim
80 words
The flush-through port device as recited in claim 4 wherein said tubular coupling member has an oval configuration in cross section at the area where said tubular member joins said body, said oval configuration area forming a lip to define a recess adjacent said outer end of said body and forming an area of increased thickness adjacent said inner end of said body, said recess receiving said valve member in said open position and said thickened area strengthening said housing.
Claim 7
Dependent Claim
51 words
The flush-through port device as recited in claim 5 wherein said outer end of said body includes an externally threaded nipple having a counterbore therein, said cap has an inverted cup-shaped configuration with an internally threaded wall for threadably engaging said nipple, and said sealing member is disposed in said counterbore.
Claim 8
Dependent Claim
55 words
The flush-through port device as recited in claim 6 wherein said sealing member is made of a resilient material and has an outer wall engaging a side surface of said counterbore and an inner wall having an inner diameter of said valve stem, said valve stem extending through said inner wall of said sealing member.
Claim 9
Dependent Claim
110 words
The flush-through port device as recited in claim 7 wherein said valve seat includes a sloping ledge extending from a first cylindrical surface to a second cylindrical surface, the diameter of said first cylindrical surface being greater than the diameter of said second cylindrical surface, and said valve member has a sloping shoulder extending from a piston-like cylindrical portion to an end cylindrical portion, said piston-like cylindrical portion having a diameter slightly less than the diameter of said first cylindrical surface, said end cylindrical portion having a diameter slightly less than the diameter of said second cylindrical surface and said sloping shoulder having a configuration mating with said sloping ledge.
Claim 10
Dependent Claim
38 words
The flush-through port device as recited in claim 8 wherein said body has a radially extending flange at said inner end and further comprising a fiberglass pad disposed between said flange and the inner surface of the hull.
Claim 11
Dependent Claim
81 words
The flush-through port device as recited in claim 1 wherein said tubular coupling member has an oval configuration in cross section at the area where said tubular coupling member joins said body, said oval configuration area forming a lip to define a recess adjacent said outer end of said body and forming an area of increased thickness adjacent said inner end of said body, said recess receiving said valve member in said open position and said thickened area strengthening said housing.
Claim 12
Dependent Claim
37 words
The flush-through port device as recited in claim 1 wherein said body has a radially extending flange at said inner end and further comprising a pad disposed between said flange and the inner surface of the hull.
