Abstract
Abstract A pipe coupling device for connecting the open ends of two axially aligned fluid conduits and including a removable disc that blocks the flow of liquid through the coupling. A cylindrical sleeve surrounds and seals against the ends of the open conduits to be connected. A slot is provided in the sleeve and is positioned to permit a disc to be inserted in the coupling in a plane transverse to the fluid conduits. The disc may be removed and the slot subsequently sealed to provide uninterrupted fluid flow through the coupling.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
168 words
A test coupling for joining the ends of two cylindrical fluid conduits to facilitate testing of the fluid system of which the conduits are a part, comprising: a resilient cylindrical sleeve member for sealingly engaging said ends of said conduits to provide a continuous fluid channel through said conduits and sleeve member; means defining an arcuate slot extending through a portion of said resilient cylindrical sleeve member; said slot positioned in a plane transverse of said conduits and intermediate the ends of said resilient cylindrical sleeve member; a disc member removably mounted in said resilient cylindrical sleeve member and extending into said slot, said disc blocking the flow of liquid through said resilient cylindrical sleeve member; said disc including an arcuate flange on the periphery of said disc, said arcuate flange abutting the exterior of said resilient cylindrical sleeve member and maintained in sealing engagement therewith when said disc member extends into said slot; and clamp means for clamping said disc in place in said resilient cylindrical sleeve.
Claim 2
Dependent Claim
168 words
A test coupling for joining the ends of two cylindrical fluid conduits to facilitate testing of the fluid system of which the conduits are a part, comprising: a resilient cylindrical sleeve member for sealingly engaging said ends of said conduits to provide a continuous fluid channel through said conduits and sleeve member; means defining an arcuate slot extending through a portion of said resilient cylindrical sleeve member; said slot positioned in a plane transverse of said conduits and intermediate the ends of said resilient cylindrical sleeve member; a disc member removably mounted in said resilient cylindrical sleeve member and extending into said slot, said disc blocking the flow of liquid through said resilient cylindrical sleeve member; said disc including an arcuate flange on the periphery of said disc, said arcuate flange abutting the exterior of said resilient cylindrical sleeve member and maintained in sealing engagement therewith when said disc member extends into said slot; and clamp means for clamping said disc in place in said resilient cylindrical sleeve.
Claim 3
Dependent Claim
49 words
The combination set forth in claim 1, wherein said resilient cylindrical sleeve member is co-axial with said conduits and surrounds the ends of said conduits, and wherein said clamp means includes clamps surrounding the cylindrical sleeve to force, and maintain the sleeve into sealing engagement with said conduit ends.
Claim 4
Dependent Claim
40 words
The combination set forth in claim 1, wherein the cylindrical sleeve member is a substantially non-resilient material, such as copper, and wherein said clamp means includes a strap extending about the periphery of said cylindrical sleeve and overlying said flange.
Claim 5
Dependent Claim
30 words
The combination set forth in claim 1, wherein said flange is a breakaway flange and is removable from said disc for replacement over said slot when said disc is removed.
Claim 6
Dependent Claim
25 words
The combination set forth in claim 1, including sealing means coacting with the clamp means for sealing said slot when said disc is removed therefrom.
Claim 7
Dependent Claim
38 words
The combination set forth in claim 1, wherein said cylindrical sleeve member is formed of a substantially non-resilient material, such as copper, and said clamp means includes said flange which is a breakaway element cooperating with said disc.
