Abstract
Abstract A hose assembly of limited conductivity designed to bleed static electric charges such as encountered in paint spraying. The assembly includes, as is conventional, a stem fitting 1, a reinforced hose 3 fitted over the stem 7 of the fitting 1, and a crimped shell 5. The novel element is a conductive coupling ring 13 that is adapted to establish an electrically conductive path between the hose coupling 1 and the conductive element 26 of the hose 3. The conductive coupling ring 13 includes a number of tines 19 and, when assembled between the coupling 1 and the hose 3 will, on its one side, seat against a shoulder 11 of the coupling 1, and the tines 19, on its other side, will penetrate the reinforcement 23 and 24 of the hose 3 and establish electrical contact with the conductive element 26.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
88 words
An anti-static hose assembly comprising a hose, an anti-static element enbedded between a cover and a tube of the hose, and a stem fitting mounted on the hose, the improvement comprising a conductive coupling ring seated between and in contacting relationship with the stem fitting and the hose: the conductive coupling ring having a plurality of tines extending away from the stem fitting and into the end of the hose in a region between the cover and the tube and into electrical contacting relationship with the anti-static element.
Claim 2
Dependent Claim
88 words
An anti-static hose assembly comprising a hose, an anti-static element enbedded between a cover and a tube of the hose, and a stem fitting mounted on the hose, the improvement comprising a conductive coupling ring seated between and in contacting relationship with the stem fitting and the hose: the conductive coupling ring having a plurality of tines extending away from the stem fitting and into the end of the hose in a region between the cover and the tube and into electrical contacting relationship with the anti-static element.
Claim 3
Dependent Claim
26 words
An anti-static hose assembly according to claim 1 wherein the anti-static element is a tape comprised of a heat sinterable thermoplastic material filled with carbon black.
Claim 4
Dependent Claim
82 words
A hose assembly including a stem fitting and a hose incorporating an anti-static element in which a conductive coupling ring is utilized to make electrical contact between the stem fitting and a conductive element in which the coupling ring is seated on its one side against a shoulder on the stem fitting and on its other side has outstanding axially aligned tines penetrating the hose in the region between a tube and a cover of the hose to engage the anti-static member.
Claim 5
Dependent Claim
82 words
A hose assembly including a stem fitting and a hose incorporating an anti-static element in which a conductive coupling ring is utilized to make electrical contact between the stem fitting and a conductive element in which the coupling ring is seated on its one side against a shoulder on the stem fitting and on its other side has outstanding axially aligned tines penetrating the hose in the region between a tube and a cover of the hose to engage the anti-static member.
Claim 6
Dependent Claim
74 words
A hose assembly according to claim 2 in which the conductive coupling ring is an annulus having a plurality of tines that: are an integral part of the annulus; are equally spaced around the annulus; are perpendicular to the plane of the annulus; and are formed by cutting partway along a cord passing through the body portion of the annulus and bending the cut portions at right angles to the plane of the annulus.
