Today in 1917, US Patent 1218724 A was issued, an invention of William F. Vosseler, for his “Beer Cooler.” There’s no Abstract, although in the description it includes this summary:
My invention relates to beer coolers of the type in which a coil is provided through which the beer must pass in the presence of a cooling medium.
The simplest Way of cooling beer as it is pumped from a barrel to a faucet is to send it through a coil which is packed in ice. In coils for this purpose, there must be as little obstruction to the flow of beer as possible. There must be also as much of an exposure to the ice as possible.
Accordingly in the Patent No. 1,099,329, of June 9th, 1914, to William Vosseler, is described a device in which an open coil is mounted in an ice box so that ice can be packed down inside the coil as well vas around it. This is the best way of quickly and adequately cooling the beer as it passes through a cooler, but it opens the way to a number of difficulties. The first of these is that to make a strong coil which will Withstand the jamming down in it of ice, it is hard to provide against agitating the beer during its passage through the coil. In the next place, it is difficult to hold the coil in place in the box against these strains, and finally it is requisite to make the whole structure as inexpensive as possible.
It is the object of my invention herein to provide against these difficulties so as to have an open coil of great durability and cheapness, in which there is little or no obstruction to the flow of the beer to cause it to foam out of the faucet, which is very undesirable.
