Éva Fazekas-József Kimmel: POTS, FLASKS AND PERCOLATORS
In the meantime coffee-houses spread all over Europe in an unheard-of way. Their popularity was, of course, due not only to coffee but to the many opportunities of education and fun and, last but not least, to their role as information centres. The next logical step of the improvement of coffee machines was to switch from small amounts to "industrial quantities" without this going to the expenses of the drink's quality. .. Edouard Loysei de la Lantais was born in the small French town Vannes in 1816, in a family of engineers and inventors. From 1830 to 1840 he was professor of physics and mechanics at Marseille University. He was author of a number of books, and himself an inventor. He sold his inventions to French and English machine factories. In 1844 he moved to England but kept staying a lot of time in his homeland, too. In 1854 he summarized his inventions under the name of "hydrostatic coffee machine". For the World Exhibition in Paris 1855 he developed a device for catering kitchens that allowed preparing 2000 portions of coffee an hour. Loysel prepared a so-called "dining-room percolator" and a model for the kitchen as well. The smaller apparatuses contained a long tube each, into which Philips retro kávéfőző, 1970-es évek, F&K gyűjtemény Philips "Retro" coffee machine, 1970s, F&K collection water had to be poured. The larger models were equipped with even longer tubes, in order to be able to use water pressure for making use of the hydraulic principle. A heating device served for reaching the suitable hydraulic pressure. The aim of this was, however - as Loysel had stressed - solely to raise the water as this was pumped through the ground coffee exclusively by hydrostatic pressure. Apparatuses operating on Loysel's principle were manufactured of silver, copper and English tin by the English firm Shaw and Fisher in Sheffield. From this device the lid could be removed and, when turned upside down, it could serve as funnel for filling in the water. Later devices were equipped with own funnels.
