Abstract
Abstract A volumetric filling device which utilizes a pair of connected chambers is selectively filled through a threeway valve with a product. The volume of the lower chamber is adjusted by vertically manipulating a displacement plug in a standpipe extending into the upper chamber. The standpipe extends into the second or upper chamber so that an overflow from the standpipe falls into the bottom portion of the upper chamber. The chamber is pressurized upon the introduction of a product with pressure in the chamber being regulated. If excessive product is introduced, it flows from the bottom chamber through the standpipe into the upper chamber and is returned through a pressure release valve to be recycled. Once a particular pressure in the upper chamber is obtained, air is forced into the upper chamber to evacuate the standpipe and lower chamber through the three-way valve and an outlet to thereby meter a precise quantity of liquid.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
Liquid metering aPparatus comprising: a closed vessel divided into upper and lower chambers by a transverse diaphram with said lower chamber having a generally upright stand pipe extending into said upper chamber above said diaphram; a spigot connected to the lower chamber thereof and adapted to be positioned with respect to a container for filling such a container; a valve in said spigot; means for introducing a liquid product into said lower chamber in a predetermined measure; means for adjusting the volume of said lower chamber and said stand pipe so that a metered quantity of product is accumulated in said lower chamber and said stand pipe jointly and compressing air therefrom in said upper chamber; means for opening said valve to exhaust said lower chamber; and, means for introducing compressed air from said upper chamber into said stand pipe and said lower chamber for evacuating the liquid product therefrom.
Claim 2
Dependent Claim
150 words
Liquid metering aPparatus comprising: a closed vessel divided into upper and lower chambers by a transverse diaphram with said lower chamber having a generally upright stand pipe extending into said upper chamber above said diaphram; a spigot connected to the lower chamber thereof and adapted to be positioned with respect to a container for filling such a container; a valve in said spigot; means for introducing a liquid product into said lower chamber in a predetermined measure; means for adjusting the volume of said lower chamber and said stand pipe so that a metered quantity of product is accumulated in said lower chamber and said stand pipe jointly and compressing air therefrom in said upper chamber; means for opening said valve to exhaust said lower chamber; and, means for introducing compressed air from said upper chamber into said stand pipe and said lower chamber for evacuating the liquid product therefrom.
Claim 3
Dependent Claim
23 words
The apparatus of claim 1 including an exhaust line connected to a pressure responsive valve from the lower portions of said upper chamber.
Claim 4
Dependent Claim
31 words
The invention of claim 1 including an external flange on said diaphragm and seal rings positioned on the opposite faces of said flange to seal said flange with said pressure vessel.
Claim 5
Dependent Claim
32 words
The structure of claim 1 wherein said valve is a three-way valve and a supply line is connected thereto, and said spigot is selectively communicated by said valve to said lower chamber.
Claim 6
Dependent Claim
19 words
The invention of claim 1 including an adjustable displacement plug telescoped into said stand pipe and adjustable in position.
Claim 7
Dependent Claim
33 words
The structure of claim 5 including an opening in said vessel above said stand pipe, and means slidably and sealingly positioning said displacement plug in said stand pipe and extending from said opening.
Claim 8
Dependent Claim
28 words
The structure of claim 6 further including a threaded shaft mounting said plug, said shaft being relatively rotated to advance and remove said plug in said stand pipe.
Claim 9
Dependent Claim
15 words
The structure of claim 7 including an externally fixed member connected to said threaded shaft.
Claim 10
Dependent Claim
18 words
The structure of claim 8 including a supportive frame structure surrounding said vessel and incorporating said fixed member.
