Abstract: 16,978. Schroedter, A., Schroedter, P., and Radlauer, S. Aug. 23. Bottling.-Relates to apparatus for filling bottles or jugs with beer. Three pump cylinders 2, 3, 4 are fixed to the table 1, which also carries the guide-rods 5 for the vertically-movable crosspieces or plates 10, 11. These plates are weighted so that they descend automatically to their lowest positions, the plate 10 being connected by the rods 12 to the heavy plate 13, while the plate 11 is connected by rods 14 to the weighted pistons 15 of the cylinders 2, 3, which are connected by pipes 6, 7 with the cylinder 4. The bottom of the cylinder 4 is connected by the adjustable pipes 33, 32, and the branch pipe 31, with the small receiver 28, which is furnished with a float valve 29 and communicates through the passage 27 with the filling-nozzle on the plate 10. The upper end of the pipe 32 is formed with lateral perforations 34, adapted to be closed by the heavy piston 35. The pumps 2, 3, 4 are employed to produce an air pressure, against which the beer enters the vessel being filled, and is so prevented from frothing. The air pressure should be slightly less than the pressure of the liquid, and can be regulated by means of the interchangeable weighting-rings 18, which are supported on the flanges 17 of sleeves 16 connected to the pump pistons. The filling-pipe 20 is connected by nuts 19 to the plate 11, and passes through the gland 43, which has an annular channel 42 connected with the supply pipe 41. The upper end of the tube 20 is formed with inlet apertures 44, which are normally closed by the weighted piston 45. The plate 11 may be operated by power, or through rods 24 from a treadle 21, and operates the plate 10 and piston 35 by engaging the head stops 40, 38 on their rods 12,36. When the treadle is depressed, the movable parts are raised into the position shown in Fig. 4, permitting the insertion of the bottle &c. 25. On the release of the treadle, the plate 11 descends until the filling-tube 20 enters the bottle &c. and its ports 44 register with the channel 42, the ports being uncovered when the weight 47 on the piston 45 is stopped by the top of the gland 43. During the first portion of the downward movement of the plate 11, the plate 10 descends until the packing-ring 39 forms a tight joint with the mouth of the bottle &c., and the piston 35 descends and closes the ports 34. On the further downward movement of the plate 11, and before the tube 20 reaches the filling position, air is forced by the pistons of the cylinders 2, 3 through the pipes 6, 7, cylinder 4, and pipes &c. 33, 32, 31, 28, 27 into the bottle &c. During the filling of the bottle &c., the air is forced out through the reservoir 28 into the cylinder 4, the piston of which rises and maintains the pressure. The filling is continued until the liquid rises into the reservoir 28 and closes the valve 29, on which the flow is automatically stopped. The treadle is again depressed to permit the removal of the filled vessel, the space left in the latter by the withdrawal of the tube 20 being filled by the liquid in the receiver 28. The piston 35 also opens the ports 34, to release the pressure in the cylinders before the next operation. The apparatus may be arranged so that the plate 11 has the short lift of the plate 10, the latter with the table 1 and vessel 25 having the longer lift of the plate 11. The cylinders 2, 3 may be united as a single cylinder, and may be combined with the pump 4.
