Abstract
Abstract A hose coupling for detachably connecting a hose to a threaded fitting such as the outlet of a faucet, a male hose coupling, or a pipe and having a nut type of a housing formed of a metallic shell containing a plastic liner which has threads for attachment to the male fitting and also provides integral seal for preventing leakage from between the threaded fitting and the hose.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
141 words
A hose coupling comprising; a tubular element having one end adapted for fastening to a hose in nonrotatable relation thereto, a housing assembly including a shell and a lining element disposed in said shell, said lining element having internal threads adapted for threaded attachment to a fitting, said shell having a radially inwardly extending portion, said lining element having a radially inwardly extending flange spaced from the portion of said shell to form an annular groove therebetween, and a collar formed by said tubular element and extending radially outwardly from the other end thereof, said collar being rotatably disposed in said annular groove for rotational movement of said housing relative to said tubular element, said flange of said lining element forming a seal engageable in sealing relationship with said collar upon engagement of said flange by an end of said fitting.
Claim 2
Dependent Claim
141 words
A hose coupling comprising; a tubular element having one end adapted for fastening to a hose in nonrotatable relation thereto, a housing assembly including a shell and a lining element disposed in said shell, said lining element having internal threads adapted for threaded attachment to a fitting, said shell having a radially inwardly extending portion, said lining element having a radially inwardly extending flange spaced from the portion of said shell to form an annular groove therebetween, and a collar formed by said tubular element and extending radially outwardly from the other end thereof, said collar being rotatably disposed in said annular groove for rotational movement of said housing relative to said tubular element, said flange of said lining element forming a seal engageable in sealing relationship with said collar upon engagement of said flange by an end of said fitting.
Claim 3
Dependent Claim
43 words
The combination of claim 1 in which the radial flange of said lining is thinner in cross section than the remainder of said fitting for deflection relative thereto and into engagement with said collar upon attachment of said hose coupling to a fitting.
Claim 4
Dependent Claim
35 words
The combination of claim 1 in which said inwardly extending flange of said lining element has a first surface in engagement with said collar and an oppositely facing second surface adapted to engage a fitting.
Claim 5
Dependent Claim
27 words
The combination of claim 3 in which one of said surfaces has a ridge portion concentric with the axis of said coupling to form a sealing surface.
Claim 6
Dependent Claim
28 words
The combination of claim 3 in which one of said surfaces forms an annular groove and in which annular portions adjacent to said groove form said sealing surface.
Claim 7
Dependent Claim
25 words
The combination of claim 5 in which the other of said surfaces has a ridge portion concentric with said coupling to form a sealing surface.
Claim 8
Dependent Claim
18 words
The combination of claim 6 in which said ridge portion is formed axially opposite to said annular groove.
Claim 9
Dependent Claim
28 words
The combination of claim 1 in which said shell is a relatively rigid metallic member and in which said fitting element is formed of a relatively resilient plastic.
Claim 10
Dependent Claim
34 words
The combination of claim 8 in which said shell has a lip portion extending radially inwardly and spaced from the flange of said shell to prevent axial displacement of said shell and lining element.
Claim 11
Dependent Claim
29 words
The combination of claim 8 in which said shell had diametrically opposed parallel flat surfaces adapted to receive a tool for rotating said housing relative to said tubular element.
Claim 12
Dependent Claim
32 words
The combination of claim 10 in which said lining element has flat surfaces complementary to said flat surfaces of said shell to prevent rotation of the latter relative to said lining element.
