Abstract
Abstract A unified structure defining a liquid dispensing apparatus mounted on a stand pipe that protrudes outwardly through an outlet passage in a tubular fitting and is adapted to be sealably mounted in one end of a liquid container. The structure also includes a dispensing valve fixed on the outer end of the stand pipe and projecting laterally therefrom, and a pair of spaced clamp members that extend in a laterally direction opposite to the dispensing valve and having a configuration which provides clamping supports for a high pressure gas canister and a manually operable hand pump in a linear arrangement relative to the direction of projection of the dispensing valve. The tubular fitting in the container includes an inlet passage which is connected to a pressure regulator valve mounted on the gas canister by a pressure supply line. The hand pump is operatively connected to the pressure supply line and, with shut-off valves being associated with both the hand pump and gas canister, either one or the other may be selectively operated to maintain the liquid within the container under pressure.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
A liquid dispensing apparatus for use in combination with a pressurized liquid container comprising, as a unified structure: a tubular fitting having inlet and outlet passages adapted to be sealably mounted in one end of said container; an elongated stand pipe extending outwardly through the outlet passage of said tubular fitting, having a dispensing valve fixed on the outer end thereof; rigid support means mounted on the stand pipe to project laterally therefrom and defining a dual cantilever arrangement projecting from the stand pipe having elongated strap elements forming clamp members; a high pressure gas canister mounted in said support means and having a regulator valve with pressure gauge to control the flow of gas therefrom and a pressure supply line operatively connecting the regulator valve to the inlet passage of said tubular fitting; and a hand-operable air pump mounted in said support means immediately adjacent to said stand pipe and operatively connected to the pressure supply line from said high pressure gas canister.
Claim 2
Dependent Claim
164 words
A liquid dispensing apparatus for use in combination with a pressurized liquid container comprising, as a unified structure: a tubular fitting having inlet and outlet passages adapted to be sealably mounted in one end of said container; an elongated stand pipe extending outwardly through the outlet passage of said tubular fitting, having a dispensing valve fixed on the outer end thereof; rigid support means mounted on the stand pipe to project laterally therefrom and defining a dual cantilever arrangement projecting from the stand pipe having elongated strap elements forming clamp members; a high pressure gas canister mounted in said support means and having a regulator valve with pressure gauge to control the flow of gas therefrom and a pressure supply line operatively connecting the regulator valve to the inlet passage of said tubular fitting; and a hand-operable air pump mounted in said support means immediately adjacent to said stand pipe and operatively connected to the pressure supply line from said high pressure gas canister.
Claim 3
Dependent Claim
35 words
The apparatus according to claim 1 wherein the pressure supply line from said high pressure gas canister includes a manually operable shut-off valve permitting the build-up of pressure within said container by said hand-operable pump.
Claim 4
Dependent Claim
39 words
The apparatus according to claim 1 wherein the connection of said hand-operable pump to the pressure supply line includes a manually operable shut-off valve for effecting uninterrupted flow of gas pressure from said high pressure canister into said container.
Claim 5
Dependent Claim
32 words
The apparatus according to claim 1 wherein said elongated strap elements forming clamps have a shape conforming to the combined configuration of said high pressure canister, hand operable pump, and stand pipe.
Claim 6
Dependent Claim
98 words
The apparatus according to claim 1 wherein the dispensing valve projects on a line transverse to the axis of the stand pipe, the pump has an elongated cylindrical body and is disposed immediately adjacent the stand pipe and generally opposite to the direction of projection of the dispensing valve, the axis of the cylindrical body is parallel to the stand pipe axis, the canister is cylindrical and its axis is parallel to the axes of the pump body and the stand pipe, and the axes of the stand pipe, pump body, and canister are in a common plane.
Claim 7
Dependent Claim
15 words
The apparatus according to claim 5 wherein the dispenser valve projects in the common plane.
