A dozen coffee-roaster patents were issued in Germany in 1880–82. Among them was one to the Emmerich Machine Factory and Iron Foundry, Van Gulpen, Lensing & von Gimborn, Emmerich, in 1882.

Numerous coffee-cooling, coffee-grinding, and coffee-making devices were patented in Germany from 1877 to 1885; among them Newstadt's coffee-extract machine in 1882, safety attachments, rapid filters, Vienna coffee makers, etc. The first Vienna coffee maker seems to have been patented in Germany in 1879.
The Emmerich Machine Factory and Iron Foundry acquired certain Danish and Austrian coffee-roaster patents in 1881, and in 1892 it was granted a German patent on a ball roaster. In the eighties this concern began the manufacture of a closed ball, or globular, roaster with gas-heater attachment. It acquired, in 1889, the rights for Germany to manufacture gas roasters under the Dutch Henneman patents of 1888. In 1892, Theodore von Gimborn was granted French and English patents on a coffee roaster employing a naked gas flame in a rotary cylinder. In 1897, the Emmericher concern was granted a German patent on an automatic circular tipping cooler with power drive. Today, this factory features the Probat and Perfekt roasters, but manufactures a general line of cylinder and ball machines for coal, coke, and gas.
Among others engaged in the manufacture of coffee machines in Germany are G. W. Barth, Ludwigsburg, and Ferd. Gothot, Mulheim on Rhur. The latter manufactures a coke or gas heated quick-roaster known as the Ideal-Rapid, and a smaller hand-power machine, of the same type, called Favour.
