Carl Immanuel Loescher

from Wikipedia, the free encyclopedia

Carl Immanuel Löscher (born July 27, 1750 in Wiederau ; † March 21, 1813 in Freiberg ) was a German designer and the inventor of the extinguisher pump ( mammoth pump ).

Life

Löscher was born as the sixth son of the pastor from Wiederau. In 1775 he enrolled at the Bergakademie Freiberg . In 1780, the mining academician was granted permission to try out the buttocks with beech shavings in order to save the expensive leather on artifacts . These turned out to be quite successful in the test, but the chips turned out to be unsuitable for use in mining in continuous operation and especially when there was a lack of impact water. In 1782 Löscher applied for a job as a mountain model master. After completing his studies, he became an assistant to the academy inspector. This was to relieve Abraham Gottlob Werner , who performed this function, from the increasing administrative burden in favor of his scientific work.

In 1785 Löscher went to Bohemia and until 1793 took over the position of miner at Count Thunschen Bergamt Klösterle an der Eger . After his marriage to the pharmacist's daughter Friederike Müller, Löscher lived in Freiberg again. After the death of his father-in-law, Löscher ran the “Zum Schwarzen Elephanten” pharmacy on the Freiberg Obermarkt himself. He also worked as a model maker. In 1813 Löscher died of typhus .

From his mining knowledge and model tests, Löscher developed various constructions and devices, about which he also published. A characteristic of Löscher's technical descriptions was his use of seemingly endless, difficult-to-understand box sentences as book titles.

The water lifting device described by him in 1797 as aerostatic artifact was not only used in various ways after his death in oil production, but also outside of mining, and over time it was called the mammoth pump . His process was also used to stir ore slurry and formed the basis for the process of cyanide leaching of gold and silver ores in Pachucatanks .
