Jiffy-Way Egg Scale  Minneapolis, green

This is the first known version to have a label showing the city of manufacture as well as having a registered trademark.

The label reads: “Jiffy-Way" / PRODUCTS, INC. / T.M. REG. PAT. OFF. / Minneapolis, Minn. / WORLD'S LARGEST MFG'S OF EGG SCALES

Therefore, this example was made between 1945 and 1948.

• It was early 1945 when the trademark was registered, and the label says “T.M. REG.”
• In 1948, Jiffy-Way was sold to its second owner, C. C. Jolly Co. of Owatonna, Minnesota; however, this example was made in Minneapolis.

The scale is designed to weigh and grade chicken eggs from small to extra large. A decal shows normal graduation of 18–30 oz (ounces) per dozen and 1½–2½ oz each egg with a rainbow of size labels.

This is a half-roberval and pendulum scale with a screw to adjust the pendulum speed. The counterweight is constructed from two sheet metal pieces adjustable by filling the center cavity (see photo of back). This counterweight was used until about 1953.

It was made under a patent by Benjamin Zimmer of Minneapolis, Minn.
