Abstract

1829. Ramsey, J., and Carter, J. H. Jan. 24. Bottling; stuppering; stoppers, internal.-Relates to an apparatus for filling bottles with aerated liquids or beverages under pressure, and consists essentially in an arrangement whereby the bottle is filled with the air or gas substantially as soon as it is placed on the filling-tube and before any liquid is admitted, the pressure being the same as that in the liquid supply tube so that the subsequent filling is effected without foaming, and without loss of time. The apparatus is especially applicable for filling bottles fitted with stoppers having valves which are antomatically closed after the filling operation. The liquid under pressure is admitted to a cylinder 10 to fill the supply pipe a, the displaced air rising through a pipe t to an air or gas receptacle s. The liquid rises in the cylinder until the pressure of the air &c. above it equals the pressure of the source of supply, when the latter is cut off. A float 16 rises with the liquid and closes a vent tube 60. The bottle is then slipped over the filling-tubej, which is carried by the part h of a split collar g, h mounted to turn on the pipe a. The valve 55 of the bottle stopper is carried away.from its seat by the end of the tube j; as shown in Fig. 6, and the bottle neck engages the end 33 of a pivoted lever 26 having attached to it the spindle 18 of a small lift valve n. This opens the valve and allows air or'gas to flow from the receptacle s through a pipe r, Fig. 1, and passages p, o, Fig. 5, to a chamber 23 beneath a diaphragm 21 attached to the spindle 18, then by way of a port 45, Fig. 4, recess 43, and passage 44 to an annular space 41 round the tube j, then through a port 40 into a chamber formed by a partition 38 in the tube j, and finally through a port 50 into the bottle. The filling-tube carrier g, h is then turned until the inner end of the tube j registers with a port k in the supply pipe, when the liquid flows through the chamber 37 of the tube j and port 51 into the bottle. The air &c. displaced from the bottle during filling returns to the receptacle s, and escapes through the vent tube 60, which has been opened by the falling of the float 16 as the liquid' fills the bottle. The carrier is then moved back and the bottle withdrawn, carrying with it the valve 55. The recess 43 is fitted with a small float valve 46 which normally rests on a ledge 70, but should any liquid find its way into the recess the valve rises and seats against the port 45. The apparatus is provided with a bottle rest 66, and with stops 75 for limiting the movement of the filling-tube carrier.
