Standard Computing Scale, Detroit Barrel-top platform
Subject
Description
This barrel-top, porcelain-coated price computing scale was sold in a highly competitive environment where other companies made a similar product. This example has a 30-pound (13.6 kg) capacity, with price graduations from 3 to 60 cents per pound. A metal plate shows Type 9158 (model number) and serial number 418929. This example was probably manufactured in the late 1930s.
A circa 1940 Standard Computing Scale Co. catalog shows this Model No. 9158 (along with an electric-lighted model, no. 9658). Standard advertised it as the "Lowest cylinder scale on the market."
Of special interest is Standard’s prolific inventor, Louis Jaenichen. Of the ten patents listed in the middle of the dial, nine are by Jaehichen. The design patent was issued in 1917, the first mechanical patent in 1911, and the last patent in 1931. See the reference, below, to learn more about this interesting man.1
