Computing Scale Co., Dayton  Beehive balance

This price computing scale has three distinguishing features, one of which gives it our common name of a “beehive” balance. It was made by The Computing Scale Company of Dayton, Ohio―commonly referred to as “Dayton” scale.

“Beehive” refers to the shape of the enclosed weights, each with a lever that adds weight to the balance—promoting “honesty” and eliminating lost weights. In this example, the weights are 1, 2, and 4 pounds, respectively. The best-known beehive mechanism was patented by Francis C. Osborn in 1905 (US793606); however, Dayton may have arranged to use it while it was still pending (filed in 1899). Osborn used it on counter scales that were not price-computing.

Other distinguishing features include the cylindrical chart-beam and the in-balance indicator (close-up photo; 1901 patent). The 1902 patent is for a rotating base.

The brass beam has a 2-pound capacity; so, when added to the beehive weights, the total capacity is 9 pounds (4 kg). The information plate also shows: No. 74 Scale (likely the model number) and Serial Number 120455.
