Today in 1956, US Patent 2739455 A was issued, an invention of E. D. Idzi, for his “Apparatus For Chilling and Dispensing Beer Glasses.” There’s no Abstract, although in the description it includes this summary:

The invention described and claimed in this divisional application consists in a new and useful improvement in apparatus for chilling and dispensing beer glasses. The particularly novel and useful features of my improved device are a freeze box and a beer glass trackway associated with the freeze box and having a blower for chilling the glasses passed there along.
