Abstract Device for rapidly determining the weight of light weight objects comprising a tubular member having a vertical duct therethrough for the passage of air. The duct is open at the top of the member and connected to means for supplying air for passage through the duct and out through the top of said member. Connected to the top of the member is a platform restricted in its lateral movement and adapted to be moved vertically to a predetermined point above said member to allow air from the duct in said member to exit beneath the platform, which platform is thereby suspended by the pressure of the exiting air. A calibrated pressure gauge is associated with the air supply means which registers the difference in pressure in the air supply means when an object to be weighed is placed on the platform and depresses the platform. The weighing device is particularly suited for rapid quality control procedures in the manufacture of light weight objects, such as cigarettes.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
87 words
A weighing device comprising a tubular member having a vertical duct therein adapted for the passage of air, said duct being opened at the top of said member, air supply means connected to said duct, a platform connected to the top of said member and adapted to be suspended above the top of said member by air passing through said duct, and means connected to said air supply means for determining the difference in pressure therein when an object to be weighed is placed on said platform.
Claim 2
Dependent Claim
87 words
A weighing device comprising a tubular member having a vertical duct therein adapted for the passage of air, said duct being opened at the top of said member, air supply means connected to said duct, a platform connected to the top of said member and adapted to be suspended above the top of said member by air passing through said duct, and means connected to said air supply means for determining the difference in pressure therein when an object to be weighed is placed on said platform.
Claim 3
Dependent Claim
20 words
The weighing device as described in claim 1, wherein the means for determining the pressure difference is a pressure gauge.
Claim 4
Dependent Claim
25 words
A weighing device as described in claim 2, wherein the pressure gauge is calibrated to determine the weight of an object placed on said platform.
Claim 5
Dependent Claim
22 words
A weighing device as described in claim 1, wherein said platform is connected to the top of said member by restraining pins.
Claim 6
Dependent Claim
33 words
A weighing device as described in claim 4, wherein said platform is adapted to allow air exiting from said vertical duct to escape into the atmosphere around the entire perimeter of said platform.
