Abstract: 8478. Schneider, A. April 11. Bottling.-Relates to apparatus for bottling liquids under pressure, the filling of the bottles being effected against an equal back pressure of compressed air or gas, so preventing foaming and deterioration of the liquid. Fig. 5 shows one form of filling-valve employed. The casing A, closed at the ends by screw-caps B, B<1>, is shaped to receive the conical plug valve D, which is held up to its seating in the casing by the spring C. The nipple I is connected to the liquid-supply tank, the fluidpressure tube K being also in communication with the tank above the level of the liquid in it. The filling-tube E, having one or more outlet ports at its lower end, is screwed into the liquid passage d of the valve, and contains a pressure-tube F, which, through the ports f, f<1> and the passage c, k in the valve, puts the tube K in communication with the interior of the bottle. The cap G, which closes the mouth of the bottle during filling, is also screwed into the valve plug, and is fitted with a lining H of india-rubber &c., having a conical central portion h adapted to stopper the mouth of the bottle. A slot g<1> is formed in the casing, to permit the oscillation of the filling-tube to open and close the valve. In the open position, as shown, the passages d, k register with the passages i, K respectively, and the liquid enters the bottle against the back pressure through the tube K, the compressed air or gas being forced back to the supply tank as the bottle is filled. The valve is closed by turning the filling-tube into an inclined position. The adjacent ends of the passages K, k are flared, so that the fluid pressure is admitted to the bottle, to equalize the pressure, before the liquid-supply passage is opened. In a modification, the nipple I is replaced by a neck I, Fig. 10, screwed exteriorly for attachment by a coupling to the filling-tank, and the casing has a projection or extension for the attachment of the support 0 of the bottle-holding fork n. In another modification, the valve plug is fixed, and the casing is moved to open and close the valve passages. The bottleholder N, Fig. 10, may be applied to any suitable filling-tube, and consists of a fork n, pivoted to t be support 0, and adapted to engage under the flange or collar of the bottle neck, the bottle being held np to the cap G by a spiral or other spring P. Modifications of the fork and of the arrangement of the controlling spring or springs are described. In the fork shown in Fig. 17, a pair of clipping or clamping arms N', pivoted together, are mounted within the arms of the fork N, which has inclined surfaces n' engaging corresponding inclined surfaces on the arms N<1>, to close the latter round the neck of the bottle. Fig. 19 shows a bottling-machine provided with filling- valves A and bottle supports N. The tank or reservoir is made in two parts R, R<1> pivoted together at one side and secured at the other side by swinging clamping-bolts r, a suitable packing being interposed between their meeting-edges. The reservoir is supported by journals S on the standards T, and is locked in adjusted position by pins inserted in recesses in the journals and journal boxes. The liquid is supplied to the reservoir through the tube U, and the air or other fluid pressure is supplied through the pipe V<5> and a shut-off valve. Excess of fluid-pressure is relieved, through an adjustable spring-controlled vent valve, during the filling of the reservoir through the supply-tube U, the passage to the vent valve being closed, by a valve controlled by the float W, when the reservoir is filled to the maximum extent.
