Collectibles-General (Antiques)/Dayton Scale


We have a Dayton Scale   style # 146... Ser # 395304.....
 Our original hope was to get the lighting to work...but it is possible that Thomas Edison made the lightbulbs (aprox 8" incandescent) just kidding
   Is it possible to get a schematic or explosion drawing and or parts....Also a picture or drawing of the original pan?  The picture I saw had a flat glass,which would work but would like to see what the original looked like....Will cover any costs
         Thank You Very Much   Jim

Hi James,

The Computing Scale Co. started manufacturing scales in 1891, in Dayton, Ohio, changed their name to Dayton Scale Co. in 1923 and was manufacturing scales under that name at least until 1929.

Dayton's model no. 146 "Direct Advertising Scale" had a small light fixture, that would have been used to illuminate the dial for the customer or shopkeeper.  Let may be able to get some help from the diagrams in the patents, the dates of which are usually shown on the scale dial or id plate.  Patent number 946447 and was issued to Charles B. Longstreth of Dayton, OH on  Jan.11, 1910, and covers an interior light for the scale chart. Patents can be read and printed by entering their numbers one at a time in the search box here: .  If you send other patent dates off the scale we can supply additional patent numbers from our scale patent data base.

Most of these scales originally had a milk glass platform. Since they were manufactured primarily for use in meat markets or general stores the milk glass platforms were easy to clean and could be sterilized.  Retail value might be $100-$350 depending on condition.

Hope this helps.
