Abstract
Abstract A weighing apparatus for weighing liquids which includes a balance beam pivotally supported from a pivot pin and having first and second members of equal weight supported on opposite sides of the pivot point, one of the members being adapted to be positioned in the liquid to be measured for displacing a predetermined volume of liquid. A fluid piston and cylinder assembly fixedly supported and in contact with the beam whereby the buoyant force exerted on the one member is transmitted to the fluid assembly and a pressure gauge connected to the assembly for measuring the pressure therein which is an indication of the weight of the liquid in which the one member is inserted. The one member including first and second horizontal sections of different cross-sectional areas with the upper cross-sectional area being smaller whereby the volume of fluid being displaced when the member is inserted in the fluid is accurately measured. The beam including a vertical extending shoulder adjacent the pivot point which is in contact with the fluid assembly thereby multiplying the buoyant force applied by the liquid to the fluid assembly.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
A weighing apparatus for liquids comprising, a pivot pin, a balance beam pivotally supported from the pin, first and second members of equal weight supported from the balance beam on opposite sides of the pin, one of which is adapted to be positioned in the liquid to be measured for displacing a predetermined volume of liquid, a fluid piston and cylinder assembly, said assembly fixedly supported and one of the piston and cylinder positioned in contact with the beam whereby the pressure in the assembly is increased when said one member is submerged into the liquid, and a pressure gauge connected to the assembly for measuring the pressure therein thereby indicating the the weight of the liquid into which the one buoyant member is inserted.
Claim 2
Dependent Claim
125 words
A weighing apparatus for liquids comprising, a pivot pin, a balance beam pivotally supported from the pin, first and second members of equal weight supported from the balance beam on opposite sides of the pin, one of which is adapted to be positioned in the liquid to be measured for displacing a predetermined volume of liquid, a fluid piston and cylinder assembly, said assembly fixedly supported and one of the piston and cylinder positioned in contact with the beam whereby the pressure in the assembly is increased when said one member is submerged into the liquid, and a pressure gauge connected to the assembly for measuring the pressure therein thereby indicating the the weight of the liquid into which the one buoyant member is inserted.
Claim 3
Dependent Claim
43 words
The apparatus of claim 1 wherein said one member includes first and second horizontal sections of different cross-sectional areas, the upper cross-sectional area being smaller whereby the volume of fluid being displaced when the member is inserted into the fluid is accurately measured.
Claim 4
Dependent Claim
36 words
The apparatus of claim 1 wherein the beam includes a vertically extending shoulder adjacent the pivot pin which is in contact with the assembly thereby multiplying the buoyant force applied to the beam by the liquid.
Claim 5
Dependent Claim
21 words
The apparatus of claim 1 including a vertically adjustable and rotatable support connected to the pivot pin for supporting the beam.
Claim 6
Dependent Claim
17 words
The apparatus of claim 1 including means for adjusting the piston and cylinder relative to the beam.
Claim 7
Dependent Claim
204 words
A weighing apparatus for liquids comprising, a pivot pin, a balance beam pivotally supported from the pin, first and second buoyant members of equal weight supported from the balance beam on opposite sides of the pin, one of which is adapted to be positioned in the liquid for displacing a predetermined volume of liquid, said beam including a shoulder adjacent the pivot pin for multiplying the buoyant force applied to the beam by the liquid when said one member is inserted into the liquid, a fluid piston and cylinder assembly, said assembly fixedly supported and one of the piston and cylinder positioned in contact with the beam shoulder whereby the pressure in the assembly is increased when said one member is submerged into the liquid, a pressure gauge connected to the assembly for measuring the pressure therein thereby indicating the weight of the liquid which is displaced by the one buoyant member, a vertically adjustable support connected to the pivot pin for supporting the beam, and said one buoyant member including first and second horizontal sections of different cross-sectional areas, the upper cross-sectional area being smalLer whereby the volume of fluid being displaced when the member is inserted into the fluid is accurately measured.
Claim 8
Dependent Claim
204 words
A weighing apparatus for liquids comprising, a pivot pin, a balance beam pivotally supported from the pin, first and second buoyant members of equal weight supported from the balance beam on opposite sides of the pin, one of which is adapted to be positioned in the liquid for displacing a predetermined volume of liquid, said beam including a shoulder adjacent the pivot pin for multiplying the buoyant force applied to the beam by the liquid when said one member is inserted into the liquid, a fluid piston and cylinder assembly, said assembly fixedly supported and one of the piston and cylinder positioned in contact with the beam shoulder whereby the pressure in the assembly is increased when said one member is submerged into the liquid, a pressure gauge connected to the assembly for measuring the pressure therein thereby indicating the weight of the liquid which is displaced by the one buoyant member, a vertically adjustable support connected to the pivot pin for supporting the beam, and said one buoyant member including first and second horizontal sections of different cross-sectional areas, the upper cross-sectional area being smalLer whereby the volume of fluid being displaced when the member is inserted into the fluid is accurately measured.
Claim 9
Dependent Claim
22 words
The apparatus of claim 6 including, means for adjusting the position of the piston and cylinder assembly relative to the beam shoulder.
