Today in 2010, US Patent 6308869 B1 was issued, an invention of Kenneth Leonard Simpson, for his “Keg and Keg Fitting For Dispensing Liquids Under Pressure.” Here’s the Abstract:
A keg for dispensing beer or other liquids under pressure is provided with a neckless spear arrangement. The spear comprises a body intended to be welded permanently to the keg with all parts of the spear assembled through that body. When so assembled escape is prevented so that in the event of interference by any unqualified person there is no risk of the spear being ejected as a missile.
