James Kelly obtained a patent for a table-top platform scale in 1856. This is the model he submitted with his patent application. The inscription on the dial reads “J. KELLY / SAG HARBOR.” That same year, Kelly showed “very accurate fractional scales” at the American Institute fair and took home a silver medal.
