- Description
- This wooden patent model for an adder has a frame that holds seven strips of wood. Each strip has 19 holes on it. The ten right holes are numbered from 0 to 9. The nine remaining holes are unnumbered, but the wood is colored green. To the sides of each strip, the numbers 1 to 9 are written on the frame. The left part of the strip is covered by an upper piece on the frame.
- Samuel S. Young of Eaton, Ohio, took out three patents for computing devices. This is the patent model for the first. The later ones were a rule for calculating interest, patented September 2, 1851 (U.S. patent 8323), and an arithmetical proof rule, patented October 26, 1858 (U.S. patent 21921).
- The U.S. Census for 1850 indicates that S. S.Young of Eaton, Ohio, was 40 years old that year, and living with his wife and two children. His occupation is given as “gardener.” Apparently by 1860 he had moved to the nearby town of Washington and is listed as a “horticulturalist” by profession.
