Farm Master Egg Scale  By Jiffy-Way, green

This "Farm Master" scale was a private label made by Jiffy-Way. It 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.

The decal reads: FARM MASTER / OUR PLEDGE OF SUPERIOR QUALITY. Jiffy Way produced scales for several private labels. (For other private labels, search for “Jiffy Way” within this website.)

This example was made after 1953, the year the counterweight was changed to a steel cylinder with an adjustment screw to ensure accuracy (see photo of back). Also, since 1948, Jiffy-Way was under its second owner, C. C. Jolly Co. of Owatonna, Minnesota, where this scale would have been made.

This is a half-roberval and pendulum scale with a screw to adjust the pendulum speed.

The patent was by Benjamin Zimmer of Minneapolis. The patent number was printed on Jiffy-Way scales for many years after it expired; so, it is not much help in dating an item.
