Today in 1871, US Patent D4641 S was issued, an invention of John P. Pears, for his “Design For Molds For Lager-Beer Glasses.” There’s no Abstract, although in the description it includes this summary:
I have invented a new and useful Design for Mold for Lager-beer Glass; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being/had to the accompanying drawing making a part of this specification, which represents a sectional view of a dropmold, and illustrates my improved design.
