Ohaus Tabletop Grain Scale

This Ohaus table-model grain scale is used to determine the weight of a bushel of grain.

This scale has a second beam on top that weighs 0 to 25 grams, and it is used with the top line on the main beam, which shows the weight of the sample in grams. The middle line on the main beam is the percent deducted after cleaning and drying, and it also shows the sample’s weight in ounces. The bottom line is pounds per bushel. Under the beam is an adjustable weight to zero-balance the beam.

The Seed Trade Reporting Bureau called this the “Four-in-One Dockage Scale” because it could be used to weigh items other than grain.

The scale can weigh measured samples in the pan, which has an end cover for pouring.

The Seed Trade Reporting Bureau used the “Seedboru” brand name, but it does not show on this scale. And its founder, LeRoy M. Smith, held the patent on this scale, contracting to the Newark Scale Works for manufacturing.

Newark Scale Works was created by the Ohaus brothers in 1914 and incorporated as OHAUS Scale Company in 1947, but we are uncertain of when NSW used the Ohaus brand. Also, the “NSW” logo can be seen on the brass hinge covers.
