Friedrich Ludloff

from Wikipedia, the free encyclopedia

Friedrich Ludloff (born April 29, 1838 in Sondershausen ; † after 1914) was a German farmer , landlord and industrialist .

Life

Friedrich Ludloff was a son of Friedrich Carl Ludloff and brother of Max Ludloff and Carl Ludloff .

education

From 1854 to 1856 he received practical agricultural training from his uncle Wilhelm Ludloff at Gut Rothof near Kissingen and then until 1858 in Schernberg near Sondershausen. In Jena he studied agriculture for two years .

Tenant and land manager

From 1859 to 1863 he managed the Seega estate near Sondershausen, then he was tenant of the Gundersleben estate near Sondershausen for seven years and tenant of the princely domain of Neustadt near Ilfeld am Harz for another ten years until 1880 . During this time Ludloff began to develop patents for his ideas.

Together with his brother Max, he and his family moved to Berlin in 1880 .

Berlin porcelain factory M. Ludloff & Co. (1880–1889)

In 1880 he and his brother Max founded the Berlin porcelain manufacturer M. Ludloff & Co. , which was dissolved again in 1899. The power of attorney for his second oldest son Robert was also deleted.

Drosse and Ludloff; F. Ludloff & Sons (1891 - unknown)

Ludloff founded his own company in Berlin in 1891. He had a patent from Dr. Otto Braun bought a noiseless hand centrifuge, a cylindrical drum with a corrugated insert (3,500 to 4,500 revolutions, 90 to 250 l per hour throughput) and bought the Dr. Braun centrifuge built in his company Drsel and Ludloff in Berlin- Martinikenfelde . In the first series, the centrifuge was driven by a cord and a gear transmission. The design provided for silent operation and easy cleaning of the drum. Due to the technical realization and continuous further development, the centrifuge offered by Ludloff was market leader for decades. These manual centrifuges were used for cleaning and skimming milk.

In 1894 the company was located at Kaiserin-Augusta-Allee 24. Ludloff continuously improved the centrifuge. As early as 1895, the modified centrifuge was offered in three sizes of 100 l, 200 l and 250 l. The company F. Ludloff & Sons, a special factory for milk extractors , Koloniestraße 115, is established, with Friedrich Ludloff's two youngest sons joining the company, one as a commercial manager, the other as a technical manager. In 1895 the hand-held centrifuge No. 7, exhibited at the exhibition of the German Agricultural Society in 1894, was also tested . In 1898 a milk centrifuge was presented in detail. This was equipped with a safety device which was supposed to prevent the drum from rotating too high. For this purpose, a friction wheel construction was used, which should ensure the correct speed despite the changed drive speed. A further development followed with the star centrifuge No. 4 . In 1904 this star milk centrifuge for manual operation was technically tested in the machine laboratory of the agricultural academy in Bonn-Poppelsdorf . Milk extractors with electric motor drive will later be offered.

In 1907, the company is named as just one of three companies in Germany that manufacture cleaning centrifuges for milk and filter dirt out of the milk without separating cream.

Further product developments (selection):

  • 1908: Stella 115 milk extractor
  • 1911: Stella H 5 milk extractor
  • 1912: Stella L milk extractor with upright blades as a monolithic drum insert for improved cleaning of the extractor
  • 1915: Beata hand centrifuge
  • 1920: Star milk extractor
  • 1930: Stella milk extractor with electric motor

The products were presented several times at the exhibition of the German Agricultural Society.

Friedrich Ludloff was married, had 4 children and was the father of Karl Ludloff .

Otto Fritz Ludloff

Otto Fritz Ludloff (born May 2, 1868 in Gundersleben , † after 1949) was a German engineer and industrialist .

Life

Fritz Ludloff was the third oldest son of Friedrich Ludloff and brother of Karl Ludloff.

education

He studied mechanical engineering for 10 semesters at the Technical University of Berlin . After completing his studies, he became the technical director of his father's company and continued to manage the company after his father's death.

Technical manager and other activities

In 1893 Fritz Ludloff became a member of the Berlin district association of the VDI . From then on he became active in the district association and used the VDI to regularly present the products manufactured in the F. Ludloff & Sons factory .

From around 1911 Ludloff began to work continuously on HÜTTE - the engineer paperback .
