patent-logo
Today in 1886, US Patent 354787 A was issued, an invention of Frederick Heyman, for his “Siphon For Beer.” There’s no Abstract, although in the description it includes these claims:

My invention has relation to siphons for containing beer and similar beverages; and it consists in the improved construction and combination of parts of a siphon having a reservoir at its top for containing compressed air or gas for the purpose of forcing the fluid out of the siphon, as hereinafter more fully described and claimed.

When beer and similar beverages are to be contained in siphons, and to be drawn oh the siphons in small quantities, it is desirable to have air or gas compressed above the fluid for the purpose of forcing it out through the drawing-tube, and it is at the same time desirable to have the said compressed air or gas contained in such a manner that it will not mix with the fluid and thus affect the properties of the beverage; and for the purpose of having the compressed air or gas contained in such a manner that it may readily be brought to bear upon the fluid in the bottle of the siphon, and at the same time not be in constant contact with the fluid, I construct an air chamber or reservoir above the bottle in which the air or gas may be contained and from which it may be let into the bottle when the pressure is required, as I shall now proceed to describe.
