Abstract
Abstract A portable gauge for measuring the fluid contents of a container having an opening circumscribed by a substantially horizontal wall portion, said gauge having a base adapted to rest on said wall portion, a transparent tubular float extended through the base for free elevational movement with respect thereto, and a scale extended longitudinally of the float adjacent to the base for visual comparison therewith, the scale being calibrated in terms of the volumetric contents of the container at various fluid levels therein.

Claim 1
Independent Claim
150 words
A gauge for measuring the fluid contents of a container having a filler opening circumscribed by a substantially horizontal portion of the container comprising a base member having an annular flange adapted to rest on said portion of the container, the flange having a plurality of concentric circles intended therein to provide weakened breakable lines whereby the flange can be selectively sized to conform to said portion of the container, an elongated float slidably extended through the base adapted to float on the contents of the container, and a scale borne by the float readable in reference to the base member to reveal the fluid level in the container, the base member providing a tubular portion with which the float is telescopically associated, and the float being a transparent tube having an open upper end and a closed lower end useable for visually inspecting samples of the fluid deposited therein.
