Abstract: 191,217. Billows, A. J. Nov. 1. 1921. Bottling; ' c r o w n corks and the like, applying. - In a machine or. rack for filling bottles with liquids under pressure, a rubber chuck is compressed round the neck of the bottle which is held in position, gas and water tight, whilst being filled, snifted, and sealed, by means of a metal disc cap, and then automatically released, by one and the same machine, removal of the bottle not being possible until sealing has taken place. The neck 7, Fig. 2, of the bottle 8 to be filled and sealed is inserted in a rubber ring 6 at the upper end of the head 3 of the rack and the bottom of the bottle is engaged by a plate 9 carried by a screw 10 in the upper bridge-piece 11 of the rack. A vertically slidable chuck 14 in the head 3 is connected bv a bush 20 and headed pin 21 to a screwed rod 19 working in the lower bridge piece 25 which, as well as the head 3, is carried by vertical guide rods 26 slidably mounted in the bridge piece 11. The chuck 14. Fig. 6, has external vertical grooves 15 in which fingers 16 with inturned upper ends 17 are resiliently held by means of one or more rubber bands 18. The lower part 27 of the rod 19 works in the bottom bridge piece 28 which is connected to the piece 11 by vertical rods 29. Stop-pins 30 carried by the piece 25 and passing through the piece 28 have rollers 31 at their lower ends to engage a spring- controlled striking plate 32 rotatably mounted on the bottom bridge piece 28. The snift passage 34,. Fig. 8, leading to atmosphere from the filling chamber 35 in the head 3 is closed by a valve 36 carried by a spring controlled lever 37 pivotally mounted on the head 3 and having a roller 38 to engage a cam 39 on the carbonating machine. In use, a metal disc cap 40 is pressed into the chuck and retained under the fingers 17 by means of a spring controlled plunger 41 slidably mounted in the chuck. After a bottle has been inserted, the screw 19 is turned bv means of its hand-wheel 23 to push the head 3 and bridge piece 25 upwards against the action of the springs 41* till the arms 42 of the head contact with adjustable stops 43 on the rods 29 thereby raising the rollers 31 clear of the hook portions 44, Fig. 4, of the plate 32 whereupon the plate 32 under the action of its spring 45 flies back against a stop 46, the rollers 31 then coming to rest upon.the upper faces of the hooks 44 and the bottle neck making a tight joint, with the rubber ring 6.. Liquid is admitted from the carbonating-machine by an opening 4 into the filling chamber 35, and the rack is rotated by means of a handle 49 carried by the upper bridge piece 11, snifting taking place each time the roller 38 engages the cam 39. The bottle being filled and the rack brought to the vertical position, the wheel 23 is further rotated to raise the chuck 14 and close the cap 40 on the mouth of the bottle: projections on a striker 24 carried by the wheel "3 then engage projections 48 on the plate 32 and push it back till the hooks 44 are moved away from below the rollers 31, whereupon the head 3, piece 25, chuck 14, screw 19, wheel 23, and striker 24 are all moved downwards bv the springs 41*.
