Today in 1959, US Patent 2909044 A was issued, an invention of John F. Wilcox, assigned to Superior Products Mfg Company, for his “Spout Cooling Apparatus.” There’s no Abstract, although in the description it includes this summary:
This invention relates to liquid coolers and dispensers and more specifically relates to apparatus for cooling liquid dispensing spouts or faucets.
This one’s interesting and worth the long read. It’s essentially adjunct brewing, but incorporating soybeans in the process, too. The fact that Archer Daniels Midland owns the rights to the patent is also a bit curious.
