Abstract
Abstract A fuel hose assembly having a swivel coupling for interconnecting the gasoline dispensing nozzle with the coaxial hose of the pump, with the swivel coupling retaining the inner and outer hose in their spaced apart positions thereby defining separate passageways while permitting the hoses to rotate relative to each other and permitting the dispensing nozzle to rotate and swivel relative to coaxial hose connection to a fuel dispensing pump.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
159 words
A swivel coupling for interconnecting a gasoline dispensing nozzle member with a coaxial hose comprising a pair of concentric rigid conduits, one of said conduits being an outer conduit and the other one of said conduits being an inner conduit, a spider interconnecting the one end of said conduits, said outer conduit cooperative with said inner conduits to define an annular passageway for conveying vapors from said nozzle to said coaxial hose, said spider having a plurality of circumferentially spaced passageways for communicating with said annular passageway, the other ends of said rigid conduits being formed into a pair of elbows, said elbows having the central axes of said ends of said conduits subtending an obtuse angle relative to each other, the inner periphery of said other end of said outer conduit being threaded, and means interconnecting said one end of said conduit to said gasoline dispensing nozzle member to permit relative rotation therebetween but prevent axial movement therebetween.
Claim 2
Dependent Claim
159 words
A swivel coupling for interconnecting a gasoline dispensing nozzle member with a coaxial hose comprising a pair of concentric rigid conduits, one of said conduits being an outer conduit and the other one of said conduits being an inner conduit, a spider interconnecting the one end of said conduits, said outer conduit cooperative with said inner conduits to define an annular passageway for conveying vapors from said nozzle to said coaxial hose, said spider having a plurality of circumferentially spaced passageways for communicating with said annular passageway, the other ends of said rigid conduits being formed into a pair of elbows, said elbows having the central axes of said ends of said conduits subtending an obtuse angle relative to each other, the inner periphery of said other end of said outer conduit being threaded, and means interconnecting said one end of said conduit to said gasoline dispensing nozzle member to permit relative rotation therebetween but prevent axial movement therebetween.
Claim 3
Dependent Claim
35 words
A swivel coupling as set forth in claim 1 wherein the outermost end portion of said threaded inner periphery of said other end of said outer conduit is flared smoothly outwardly for receiving an o-ring.
Claim 4
Dependent Claim
96 words
A swivel coupling as set forth in claim 2 wherein said interconnecting means includes a circumferential groove in the outer periphery of said one end of said outer conduit and a complimentary groove in the inner periphery of said nozzle member, bearing means disposed in said grooves operative to facilitate rotation between said coupling and said nozzle member but operative to prevent linear movement therebetween, a threaded bore in said nozzle member communicating with said groove in said nozzle member, and a threaded member disposed in said threaded bore to retain said bearings in said grooves.
Claim 5
Dependent Claim
19 words
A swivel coupling as set forth in claim 3 wherein said bearing means are a plurality of spherical bearings.
Claim 6
Dependent Claim
32 words
A swivel coupling as set forth in claim 4 wherein said one end of said inner conduit has a reduced outer periphery for complimentary engaging an inner conduit on said dispensing nozzle.
Claim 7
Dependent Claim
98 words
A swivel coupling as set forth in claim 1 wherein said one end of said inner conduit has a reduced outer periphery, said interconnecting means includes an adapter, said adapter having a pair of outwardly extending tubular members, one of said tubular members having its inner periphery recessed to receive said reduced one end of said inner conduit, the other one of said tubular members communicating with said annular passageway through said passageways of said spider, and said other one of said tubular members having its central axis parallel to the central axis of said one tubular member.
Claim 8
Dependent Claim
33 words
A swivel coupling as set forth in claim 6 wherein each of said pair of tubular members has a threaded nut rotatably journaled thereon for connecting said swivel coupling to said dispensing nozzle.
Claim 9
Dependent Claim
78 words
A swivel coupling for interconnecting a gasoline dispensing nozzle member with a coaxial hose as set forth in claim 1 wherein said one end of said outer conduit has a rotatably nut journaled thereon, said nut having a circumferentially extending groove on the inner periphery thereof, an o-ring mounted in said groove frictionally engaging the outer peripheral surface of said outer conduit, and an externally threaded reduced end portion on said nut for threadedly engaging said nozzle member.
