Today in 1977, US Patent 4055202 A was issued, an invention of James Albert Greene, for his “In-Case Bottle Filling Apparatus.” Here’s the Abstract:
A bottle filling device which raises in-case bottles to be filled to engagement with a fill valve assembly which controls fluid communication between a fill tube inserted into each bottle and a pressurized fill tank. Cup members, which engage the bottle openings in fill position, communicate with a vacuum line, such that the combination of pressurized fill source and air-evacuated bottles realizes extremely fast filling. The fill tubes are the shafts of respective double acting fluid pressure operated cylinders of simple construction which position a port in the fill tube upper wall extremes within the fill tank confines or within pressure sealing cylinder end bushings to define respective open and closed fill-valve conditions.
