Today in 1894, US Patent 530827 A was issued, an invention of William R. Dales, for his “Beer Drawing and Saving Apparatus.” There’s no Abstract, although in the description it includes these claims:

The object of my invention is to produce an apparatus which enables beer to be readily drawn to fill a glass or other receptacle, and which has also an arrangement by which the froth may be sucked from the glass and delivered into a receptacle from which, after it settles, it may be withdrawn in the shape of merchantable beer. The apparatus thus provides for selling beer on draft in the usual way, while cans and such articles may be filled from the receptacle into which the froth has been delivered. To these ends my invention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed.
