Today in 1911, US Patent 981768 A was issued, an invention of Alvin N. Ketterer, for his “Jetting Attachment For Bottle-Fillers.” There’s no Abstract, although in the description it includes this summary:

My invention relates to improvements in jetting attachments which are designed to control and direct jets of beer into bottles, one at a time in succession; the objects of which are to provide an attachment of this class, which can readily be attached to the discharge chute of beer bottle fillers now. Further objects are to so construct a jetting device that the same shall be extremely. simple, substantial and durable, and not liable to get out of order, be extremely cheap in cost of manufacture, and require but little attention or care.
