On 17 August 1858, one Leonard N. Nutz, a machinist from Alton, Illinois, received a patent (US patent №21236) for a single column adding device, which was the fourth in the USA keyboard adder (after the machines of Dubois D. Parmelee, Orlando Lane Castle, and Thomas Hill), and eighth in the world (after the machines of James White, Luigi Torchi, Jean-Baptiste Schwilgué, and Ernest-Narcisse Lobbé). The patent of Nutz was assigned to Judge Irwin Blackman Randle (1811-1893, an Alton lawyer) and Elias Hibbard (1795-1873, a wealthy Alton businessman), who obviously financed and ordered the device to Nutz. Moreover, Judge Randle’s son—Irwin Blackman Randle Jr. (1834-1898), the Township Assessor, Deputy Sherif, and Town Councilman, signed as a witness of the patent.
Interestingly enough, Orlando Lane Castle, who received his first patent only several months before Nutz (24 November 1857), also lived in Alton (Mark Twain once referred to Alton as a “dismal little river town”). It’s hard to believe, that living in this little town (in the 1850s Alton’s population was between 4000 and 5000 people) Castle and Nutz didn’t know each other and didn’t share their ideas. Most probably, Nutz was involved in the manufacturing of Castle’s machines (Castle was a Professor at Shurtleff College, Upper Alton, so he definitely needed a good mechanic).
Besides the patent, nothing is known about the machine of Nutz, so probably it remained only on paper and the assignors (Randle and Hibbard) didn’t manage to set up its production. Even the original U.S. Patent Model (up to 1880, the Patent Office required inventors to submit a model with their patent application) seems to be lost or destroyed. So we have no choice, but to examine the calculator of Nutz, using the patent drawing (see the drawing below).
The calculator of Nutz is a single-column adding device with a simple, but obviously well-designed and reliable construction.
The innovative technical solution in the construction is the adjustable shaft fixed by a catch (marked with a D in the patent drawing), which actually was the claim of the patent. The shaft has one or more feather-keys thereon for the purpose of clutching and giving motion to the block of the indicator corresponding with the column one wishes to add.
If for example an addition of several multi-digital numbers must be performed, firstly all units must be entered, using the keyboard. Then the catch is lifted from the shaft D and the shaft is pushed in, so as to clutch the block of the indicator of tens. The indicator of tens is then in gear with the keys of the keyboard, and the addition of this column is proceeded with in like manner to that of the column of units. By thus continuing to change the connection between the shaft and the indicators from one corresponding to the column where the addition is completed to the next following, any number of columns may be added up and registered by the use of the same keyboard.
The indicators are endless chains passing over two square blocks and numbered from 0 to 9. At intervals of every ten links is a pin for the purpose of operating on a lever, which in turn acts upon another pin on the rear side of the next indicator and moves it forward one link for every ten links, that indicator the next preceding has been moved.
Biography of Leonard Nutz
Leonard Nice Nutz (named after his grandfather, Leonard Nutz Sr.) was born on 14 October 1810, probably in the house of his grandfather (pictured below) in Germantown (nowadays part of the city of Philadelphia, Pennsylvania). His parents were William Nutz (born 23 Nov. 1777) from Germantown, and Susannah Nice (b. 1781–d. 2 Sep. 1848) from Nicetown (today also part of the city of Philadelphia), who married on 7 Sep. 1803 in Germantown, and had two children: Leonard Nice and William Nice (b. 1811).
William Nutz and his younger brother John worked as tanners with their father— Leonard Nutz Sr., who was one of the wealthiest people in Germantown, and a nice portrait of his wife Margaretha (Keyser) Nutz (1748-1812) is kept in Philadelphia Museum of Art (see below). They had 7 children: Elizabeth (b. 1769), Sarah (b. 1771), Christianna (b. 1774), Leonard (b. 1775), William (b. 1777), and John (b. 1779).
Leonard Nice Nutz was married twice. In 1836 he married in Clermont, Ohio, to Rebecca Clutch (1812-1845). Their children were Susanna Nice (1837-1920), William (b. 1838), Francis Johnston (1840-1887), Leonard McDonald (b. 1842), and Rebecca (1843-1846).
On 27 November 1846, a year after the death of his first wife Rebecca, Leonard married a second time, Susan Catherine Cochran (4 Sep 1827-27 Aug 1901) from Maysville, Mason Co., KY. Their children were Theodore Marston (3 Apr 1850-12 Apr 1927), Charles (1853-1918), the twins Carrie Belle (1858-1928) and Harry (1858-1885), Mary (b. 1859), George Washington (1861-1910), and Rebecca (died in infancy).
Leonard Nutz lived in St. Louis for some 10 years (c. 1847 until 1857) and is listed several times in the St. Louis City Directory; in 1848 he is listed as a machinist, residing at 158 Olive Street. He is next listed in 1851, giving machinist as his trade. In the 1852 Directory Nutz is again listed as a machinist, located at 10 Second Street. In the 1857 Directory, Leonard Nutz is listed as a mathematical and philosophical instrument maker.
A nice compass (19 inches in length and 8.25 inches in diameter), made by Leonard Nutz for the surveyor Benaiah Robinson in 1853, survived to our time (see the nearby image), and is kept now in the collection of Madison County Historical Society.
In late 1857 Leonard Nutz moved with his family to Alton, Illinois, where he died on 16 November 1870. His sons Theodore, Charles, and George also became splendid mechanics, made a success in business, and became prominent citizens of Alton in their line.
