Today in 1892, US Patent 349178 A was issued, an invention of Stanislas Rouart, for his “Cooling Air and Apparatus Therefor.” There’s no Abstract, although in the description it includes these claims:
The main object of my invention is to effectively cool the air of rooms or spaces in which it is necessary or desirable to maintain a free circulation of air as, for instance, in cellars for storing or treating beer, etc.
