Friedrich Kaiser (mechanical engineer)

from Wikipedia, the free encyclopedia

Friedrich Kaiser (born July 25, 1831 in Iserlohn ; † February 28, 1897 there ) was a German locksmith, mechanical engineering entrepreneur and inventor .

Live and act

Friedrich Kaiser was a son of the tailor and Bible messenger Johannes Kaiser (1805-1859) and his wife Catharina Kaiser geb. Schnadt (1804-1868). The paternal grandfather was the shoemaker Heinrich from Amecke . A brother or cousin named John worked as a needle champion at the Iserlohn-based company Stephan Witte & Co .

Kaiser completed an apprenticeship as a locksmith and opened his own "art locksmith's shop, blacksmith's shop and iron turning shop" in Iserlohn in 1860. He was interested in further technical developments, especially for the mechanization of the needle industry in Iserlohn. With the help of his experienced brother or cousin Johannes Kaiser, after several years and at great expense, he was able to manufacture automatic tamping machines. The machines that stamped needle holes independently took over work in nail production that had previously been done with English hand stamping and represented a significant step forward. Kaiser produced the systems in his workshop in Iserlohn.

In 1867 Johannes Kaiser installed a "Kaisersche ramming machine" for the first time at Stephan Witte & Co. in Iserlohn. Friedrich Kaiser, who invented this and had financial problems, trained specialists who could operate the machines and thus enabled him to successfully sell far outside of Iserlohn. In 1872 he enlarged his workshop and took up the idea of ​​a homeworker for an improved punching machine. This produced a six times higher quantity of needles in better quality and was able to quickly process the increased preproduction due to the tamping machine.

In 1837 Kaiser had more than 15 employees who made 20 ramming or hammering machines and 80 punching machines. His son-in-law Paul Schnadt and his brother and engineer Robert Schnadt invented a combined, automated ram punching machine that made Kaiser's two systems superfluous. Kaiser received patents for his systems , which he offered needle manufacturers worldwide. With his two inventions he laid the most important cornerstone for the successful development of the needle industry in his hometown.

family

Kaiser was married to Juliane geb. Schnadt (1837–1910), with whom he had two sons and three daughters. The son Ernst (1865–1902) continued his father's company. The son Friedrich was a co-owner of the large bookbindery Huncke & Schröder .
