Today in 1915, US Patent 1155009 A was issued, an invention of Simon Schlangen and Nicholas Schlangen, for their “Beer-Racking Apparatus.” There’s no Abstract, although in the description it includes this summary:
This invention relates to improvements in Beer-Racking Apparatus, of which the following is a specification.
Among the objects’aimed at by the invention are; to provide a construction whereby it shall be possible to secure an even and uniform filling of the packages regardless of the variations in the amounts of expansion and contraction which different packages exhibit under the application and release of the counter-pressure to which they are subjected in the filling operation, to provide a construction not requiring any adjustment of parts to adapt it to the filling of packages of different sizes; to provide a construction wherein the contents of the filled package shall be vented to the atmosphere through the counter-pressure return pipe during the withdrawal of the filling tube from the package, thereby insuring the complete filling of the package by back-flow oi liquid from the counter-pressure return pipe to fill the space created by the withdrawal oi the filling tube regardless of the amount of expansion and contraction of the package; to provide a construction which will more effectively prevent waste and loss of beer at the bung of the package when the 3 seal is broken; and generally, to provide a simplified and improved racking mechanism of the type referred to.
