Today in 1934, US Patent 1966384 A was issued, an invention of David A. Fenichell and Samuel Gabel, for their “Beer Barrel Bung.” There’s no Abstract, although in the description it includes this summary:
This invention relates to a bung especially intended for use on beer barrels, and has for an object to provide a bung which will have all the strength of the normal bung and yet at the same time wherein the spigot may be driven into the barrel through the bung with much less difficulty.
A further object of this invention is to provide a beer barrel bung which will allow the stopper portion to be easily driven therefrom by the spigot without exerting more than the minimum strain on the annulus of the bung, thus eliminating the possibility of splitting the annulus.
