To fillavhoin it may 50mm.-
'Be it known that I, GUSTAV Mar, a subject-of the King of Prussia. residing at 'Prinzenthal, near Bromberg, in the Kingthe 'main for'kitchen or other purposes, so-
I frigerator, through which tl dom of Prussia and German Empire, have invented new and useful Im rovement-s in Refrigerators, of which the llow'ing is a specification.
My invention relates to a refrigerator, which is so Connected with a water main that the eatables contained therein are periodically cooled and ventilated.
The cooling operation is carried out by the Water being carried by a pipe through the apparatus, while the ventilation is effegt; ed by'the'iwater passing through an ejector.
into the refrigerator, both the cooling and ventilating operations being carriedv out automatacally'each time water is taken from that the cooling and ventilation are done unconsciously and without expensqor risk of theirbeing forgotten, as in the casewheie special apparatus are provided for such operatlons.
In the accompanying drawing illustrating my invention in section, (I; designates the reie water is carpipe I), being then carried which forms an extension of the pipe b to the ejector e. Said refrigerator a is connected withthe ejector by the air pipe c as well, so that theai'r, drawn in by the ejector 6 through the pipef, is caused ried by the main off by the pipe 65,
to enter the refrigcratorthrough the pipe 0, said air escaping through the openings i at the bottom of the refrigerator. The water issues through the nozzle 9, which, like the usual taps, is arranged over a gully k, sink.
or the like.
The apparatus described operates in the following manner: The water drawn off at g for any desirod'purpoee for example for cooking, washing, drinking, etc., in passing through the pipe I) cools the apparatus a and arrives through the pipe (1 into the ejector 0, where it sucks in the air through the pipe f and then drivessaid air towards the refrigerator a through the pipe 0. It is evident therefore that both the cooling and ventilation of the refrigerator o are carried out without cost.
What I claim and desire to secure by Letters Patent of theUnited'States is The combination with a Water main, of a refrigerator through which said water main is carried, an'ejector interposed-in said 'ater main, an air inlet pipe leading, to said ejec tor, and an air outlet pipe-,oonnecting said ejector with said refrigerator, substantially as, and for the purpose, set forth.
