“*Klieg, Klieg, Klieg—Du bist a Nar. You are smart, smart, smart—but you are not so smart!*

A Yiddish saying

In the late 19^{th} and early 20^{th} century Charles Schachan Labofish (1861-1925), a machinist and Jewish immigrant from Odessa, Russian Empire, who came to America in 1888, devised various machines (calculating machines, typewriters, log-sawing machine, cyclometers, indicating device for bicycles, brush-machine, gage, etc.) and received some fifteen US, Canada and Great Britain patents for his devices, six of them for calculating machines (US533361, US544360, US661058, US673877, CA51938, and GB190101736).

For his first patent for calculating machine Labofish applied in December 1893, and the patent was granted in January 1895 (see the lower patent drawing). The first two patents for calculating devices of Labofish are describing a watch-like adding machine. Let’s examine the first calculating machine, using the patent drawing of US patent No. 533361.

The object of Labofish’s invention is to produce a very simple and efficient calculating machine, which may be made in the form of a watch and conveniently carried in the pocket, which operates without keys and is not likely to get out of order or make mistakes, and which may be easily operated to perform the various operations in addition, subtraction, multiplication, and division.

The device has several number wheels (marked with *16* in the drawing), each number wheel having on its face concentric rows of figures from 0 to 9, the rows being arranged in reverse order, with their 0’s on the same radial line as shown clearly in *Fig. 2*, and the rows of figures on each wheel are dissimilar, preferably both in style and color, so that one row may be readily distinguished from the other. The object of this reverse arrangement is to enable one row of numbers to be used in addition and multiplication, and the other row to be used in subtraction and division. The number wheels are arranged to represent units, tens, hundreds, etc., as in *Fig. 1* are shown seven of them, but any necessary number of wheels may be used.

In order to provide for carrying “one” in working the machine, it is necessary to have means for turning one wheel a distance of one number at each rotation of the adjacent wheel representing a lower denomination, and to this end each barrel *17* has on one side a projecting stud or tooth *26*, which is adapted to engage the notched or forked end *27* of a lever *28*, which is pivoted on the base *19* just below the pinion *23*, and the lever projects over the next adjacent base and is provided with a pivoted pawl *29*, which is adapted to engage the pinion of the next number wheel, the lever and its pawl being held in engagement with the stud and the pinion by springs *30* and *31*.

The machine is operated by turning the crown head *34* to the right, according to the numbers to be added, multiplied, subtracted, or divided. In operating the machine, the number wheels to be moved are pressed inward by pushing one of the push buttons *22*, thus throwing its pinion *23* into gear with the driving gear *24*, and then, by turning the crown head *34*, while the pinion is held in gear with the gear wheel the appropriate number wheel is rotated.

Let’s suppose, for instance, that the number 341 is to be added to the number already indicated on the face of the machine. The push button *22* opposite the units slot is pushed inward, thus throwing the units pinion *23* into engagement with the gear wheel *24*, and the crown head *34* is pushed inward slightly and turned to the right a distance of one number, thereby turning the units wheel a corresponding distance by means of the gear connection described, and if the number 5, for instance, has been previously shown in the said slot over the units number wheel, the number 6 will now appear and, after this, the pressure on the push button is removed and the crown head pulled out slightly so as to release it from the spring detent *38* and permit it to return to its normal position. The push button of the tens wheels is then pushed in, thus throwing the tens number wheel into gear and the crown head is then turned a distance of four numbers, thus moving the tens number wheel a corresponding distance and adding 4 to the amount already shown in the tens sight slot. The operation is then repeated on the hundreds number wheel, this being turned at a distance of three numbers and the sum is then registered and exhibited in the sight slots. If the sum of any two numbers exceeds ten, tooth *26* of the number wheel, being operated, is brought into engagement with the lever *27* which is tilted and turns the next number wheel of a higher denomination one notch or number. The sums in addition are exhibited by the inner row of figures in the sight slots, and if subtraction or division is performed, the result is shown by the outer row of figures.

In subtracting, the operation is exactly as in adding, except that reference is made to the outer row of figures in the sight slot, and if the crown head is turned to the right the outer row of numbers diminishes at the same rate that the inner row increase. If then the number 341 is to be subtracted from the number already shown on the dial of the machine, the same steps are taken as above described, but in the units, tens, and hundreds sight slots numbers will appear which are 1, 4, and 3 respectively, less than the numbers previously shown.

As multiplication is successive additions and division successive subtraction, it will be readily seen that these operations may be performed by simply turning the crown head in a manner to repeat the additions or subtractions.

The next two patents of Labofish are describing calculating devices for typewriters (see the nearby drawing from US patent No. 673877).

The object of this invention is to simplify the means used for calculating purposes and to provide sure means of extending the usefulness of such devices by constructing the same so compact and of such a nature and so entirely automatic as to make its application to a typewriting machine perfectly practical, so that the mere writing of a column of figures on the typewriter will simultaneously register and add the said column of figures within the device automatically without encumbering the typewriter in the least.

#### Biography of Charles Labofish

Charles Schachan Labofish (Labofitz) was from a possibly German or Ashkenazi Jewish family, but he was born in Odessa, Russian Empire, in April 1861 (most probably as Карл Лейбовиц). He was the son of Eiel Labofitz and Dora Brier. In the 19^{th} century Odessa was an important Russian town with a large Jewish population.

In 1884 Charles married Rose Ethel Rabinovitch-Lamlec, from a well-to-do Jewish family from Odessa. Rose was born on 12 May 1864 (although on her tombstone is specified 1868, and she died on 3 March 1948 in Washington, D.C.), and their first child (William Harry, 1885–1966) was born on 20 December 1885 in Odessa.

In the middle 1880s the family of Charles Labofish led an easy life in Odessa, and Charles worked as a main representative of Singer Corporation, the famous American manufacturer of sewing machines. It was not long, however, before they had troubles.

The Jews in Russia were subject to anti-Semitism, and a series of pogroms (massacres) against Jews in Odessa occurred in 1821, 1859, 1871, 1881, 1886 and 1905. In 1886 pogrom was killed the father of Rose Ethel, a rich local merchant, thus the family decided to leave Russia and seek a more secured place for life.

They spent some time in Dunayevtsy (Dinovitz), another Russian town with a large Jewish population, where on 20 November 1887 was born their second child—Louis Willard (1887–1988). In 1888 they moved to Germany, and soon after immigrated to America, settling initially in New York, then in Pennsylvania and Washington, D.C.

In the USA the family had two other children—John Paul (1896-1956) and Lillian Ethel (1898-1988). John Paul Labofish became a lawyer in Washington, and he was the grandfather of the famous American actor, filmmaker, and screenwriter Sylvester Stallone.

In the 1890s Charles worked in a bicycle show in Washington as machinist, and invented some devices for bicycles, like cyclometer and indicating device, as well as several calculating devices. Later he turned his inventive mind to typewriting machines and worked for Remington Typewriter Company.

In the early 1900s Charles Labofish worked as a district judge and attorney and counselor in patent causes. In 1911 he published a book, *How to win fortune by inventing*. He was a keen weightlifter who had shared a room with the bodybuilding pioneer Charles Atlas.

Early in 1916, we found Charles Labofish in Chicago, where he got a divorce from his first wife and later he married Mary Watson Zimmerman (b. 1891:-) on 30 March 1916 in Lake County, Indiana.

Charles Schachan Labofish died on 10 September 1925 (aged 64) in Los Angeles, California.
