Bottle filling device

A bottle filling device comprising a rotatable liquid reservoir, a plurality of filling heads connected to the base of the reservoir and rotatable therewith to each move between first and second filling stations, each filling head being engageable with a bottle at the first filling station, and disengagable therewith at the second filling station, each filling head having a first tube terminating below the level of the liquid in the reservoir and a second tube extending above the level of the liquid in the reservoir, valve means at the lower ends of the first and second tubes adapted to open the first and second tubes at or after the first filling station and to close them at or before the second filling station, and gas introduction means adapted to force a blast of gas down the second tube at the first filling station or intermediate the first and second filling stations to remove any liquid therefrom and to allow gas displaced by the filling of the bottle to be vented upwardly through the second tube until the liquid in the bottle rises to the level of the lower end of the second tube, each of said second tubes having an upper end that opens into a planar annular ring which is adapted to rotate with the filling heads, and said gas introduction means having a stationary gas distribution head resting on said ring and adapted to introduce a gas charge into each of said second tubes as it passes beneath the gas distribution head.
