Abstract
Abstract A measuring, metering, and mixing can, particularly for gasoline and oil, including a gasoline container with filler cap and spout; and oil container with filler cap; visual type gauges for each container; and a plunger-cylinder metering unit for withdrawing a selected amount of oil from the oil container and injecting the same into the gasoline can for producing an oil-gasoline mixture. The visual gauge on the gasoline container and the visual gauge on the oil container permit the metering of an exact amount of oil, dependent upon the amount of gasoline within the gasoline container for a precise ratio of oil-gasoline in the mixture. A hinged cover on the can protects the metering equipment during periods of non-use.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
134 words
A portable measuring, metering, and mixing can comprising: a first compartment provided with a filler spout and a pour spout; a first compartment gauge for visually determining an amount of liquid within said compartment; and a second compartment provided with a filler spout; a second compartment gauge for visually determining an amount of liquid within said second compartment; and metering means in fluid communication with said first and second compartments for withdrawing a selected amount of liquid from said second compartment as visually determined by said second compartment gauge, based upon an amount of liquid in said first compartment as visually determined by its gauge, and injecting said liquid into said first compartment for mixing in to a predetermined ratio based upon the volume of said first compartment and the ratio of liquids desired.
Claim 2
Dependent Claim
134 words
A portable measuring, metering, and mixing can comprising: a first compartment provided with a filler spout and a pour spout; a first compartment gauge for visually determining an amount of liquid within said compartment; and a second compartment provided with a filler spout; a second compartment gauge for visually determining an amount of liquid within said second compartment; and metering means in fluid communication with said first and second compartments for withdrawing a selected amount of liquid from said second compartment as visually determined by said second compartment gauge, based upon an amount of liquid in said first compartment as visually determined by its gauge, and injecting said liquid into said first compartment for mixing in to a predetermined ratio based upon the volume of said first compartment and the ratio of liquids desired.
Claim 3
Dependent Claim
53 words
