Abstract: 19,876. Laubach, H. Sept. 15. Bottling. - R e - lates to bottling- apparatus for beer and other beverages containing carbonic acid, and m o r e particularly to that type of apparatus in which the liquid is delivered under pressure to the bottle, from an intermediate receptacle between the bottle and the supply cask or reservoir, against an equivalent back pressure of compressed air or gas previously admitted to the bottle from the intermediate receptacle, with the object of avoiding frothing. In the present invention, the movable part 8, Fig. 2, of the bottling guard is carried by the slotted arm 12, which is pivoted to an arm 10 on the casing 1 of the bottling-cock 3, the slot 14 in the arm 12 being engaged by the pin 15 mounted on an arm 16 of the operating-lever 9 of the cock. When the cock is closed, the guard 8 is fully open, to permit the removal and insertion of the bottles. The bottles, which are of the screw-stoppered type, are held, during filling, by screwing their necks on to a correspondingly threaded part of the filling-nozzle 4, which is provided with an elastic packing-piece 5. The screw threads may be formed on the filling-tube 18. When the cock and bottle are turned into the position, as shown in Fig. 2, to admit the gas pressure to the bottle through the pipe 20, passage 21, and pipe 22, the pin 15 working in the curved part of the slot 14 causes the guard to move more rapidly than the bottle, so that the guard is, as shown, in position to protect the operator by the time that the gas-way is opened. During the further movement of the cock and bottle, to open the liquid-way 17, 19, the pin 15 working in the straight part of the slot 14 moves the guard with the bottle into its closed position. Figs. 6 and 8 show a modified apparatus adapted for plainnecked bottles. The bottle is held up to the nozzle 4 by two spring-controlled shoes 27, which are mounted on levers 28 pivoted to arms 30 fixed on the extended ends of the cock-spindle 31. When the cock, together with the bottle, is returned to the closed position, the jaws are opened by the projections 36 of the levers 28 bearing against the projections 37 on the casing, to release the bottle. The pin 15 for operating the guard is carried directly by the lever 9. The intermediate receptacle 24 may be shaped in cross-section as shown in Fig. 6, or may be of any other shape, the form shown being especially adapted for the arrangement of a number of bottling-cocks side by side. This apparatus is also adapted to obviate frothing which may occur when a single passage is employed both for admitting the gas pressure to and discharging it from the bottle. With a single passage only, the escaping gas may carry particles of the liquid into the passage, whence they are carried back by the gas admitted to the next bottle, causing the liberation of gas and consequent frothing. In the present invention, two independent passages are provided for the admission and discharge of the gas. The two tubes 20, Fig. 6, open into passages 39 in the socket 2 of the casing, and through the passages 40 in the cock 3 are put in communication at 41. with the upper ends of the tubes 42 in the filling-tube 18. The tube 42 through which the gas pressure is delivered to the bottle opens at the bottom 47, Fig. 8, of the filling-tube, while the tube which serves to convey the gas from the bottle opens laterally at 48 further up the filling. tube. To facilitate cleaning the filling nozzle, passages, &c., the nozzle is formed with a partly-conical and partly-cylindrical extension 45, and is secured in the cock 3 by a conical nut 49 at the upper end of this extension. An aperture, normally closed by a screw stopper 52, Fig. 6, is formed in the casing, to give admission to the nut 49. The liquid-supply passage in the cock communicates with the filling-tube 18 through the chamber 43 in the extension 45, white the tubes 42 pass obliquely through the walls of the extension into communication with the passages 40.
