Today in 1912, US Patent 1034557 A was issued, an invention of Max Adamowski, for his “Beer Spraying Device.” There’s no Abstract, although in the description it includes these claims:

My invention relates to improvement-s in spraying devices for faucets and more specifically to devices of this character especially designed for use in beer faucets. a

Ordinarily spraying of beer at the faucet as it is drawn is not desired since such spraying results in the formation of foam. However, Where a large bucket or can trade is carried on this spraying to facilitate the formation of foam is desired since the buckets or cans brought by the purchasers are of greater capacity than the amount which is purchased. The bartender in catering to this class of trade is desirous of filling the can or bucket irrespective of the size thereof for-.the amount tendered. This being so the object in forming a large amount of foam in the top of the can or bucket is obvious.

The object of my invention then is the production of the spraying device of the character mentioned, which will be effective in the formation of foam in the receptacle into which the liquid or beer is disposed, and further, a spraying device which will be of simple and economical construction, hence of low cost to manufacture.
