FILLING-VALVE.

SIEGIFICATION forming part of Letters Patent No. 717,628, dated January 6, 1903.

Application filed March 2'7, 1902. Serial No. 100,321. (No model.)

To all whom it may concern:

Be it known that I, ADOLPH SCHNEIDER, a citizen of the United States, residing at Ohicage, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Filling-Valves, of which the following is a specification.

The object of this invention is to construct a valve for use in the bottling of liquids un-' der pressure and by means of which a charge of carbonic-acid gas or other medium can be injected into the bottle before the admission thereinto of the liquid and which will also enable the liquid to be bottled under the conditions of equal pressure in the receptacle from which the liquid is drawn and in the bottle for the equal pressure to act to prevent the foaming of the liquid in the bottling operation, as well as insuring against deterioration of the liquid or loss in bottling. The valve in order to fulfil the requirements of supplying carbonic-acid gas or other medium and to enable thebottle to be filled under an equal pressure must have a construction which will allow the'carbonic acid gas or other medium under excessive pressure to be first admitted to the bottle for the excessive pressure of the carbonic acid gas or other medium to resist the flow of the liquid into the bottle until the excess of pressure in the bottle of the carbonic-acid gas or other medium is equalized with the pressure in the filling-tank, and with the equalizing of the pressure between the filling-tank and the bottle the liquid is free to flow by gravity into the bottle and as the bottle fills with the liqquid force out the carbonic-acid gas or other medium. I

The primary object of the present inven tion is to construct a simple, effective, and reliable valve,practically adapted for use with filling-machines,-for first introducing into the bottle a supply or charge of carbonic-acid gas or other medium under an excess of pressure and then opening communication between the bottle and the liquid containing tank for equalizing the pressure to allow the liquid to flow into the bottle; to improve the construction of the valve as to the arrangement of the supply-passages for the carbonic-acid gas or other medium, the pressure and vent passages and the liquid-supply passages in the casing or shell, and the controlling-plug of the valve; to give the carbonic-acid gas or other medium, the pressure relief, and the liquid separate lines of travel, so arranged as to first admit the carbonic-acid gas or other medium under pressure and then open the vent for equalizing the pressure and the passage for admitting the liquid, and to simplify and improve the construction and operation of the constituent elements which enter into the construction of the valveas a whole.

The invention consists in the features of construction and combinations of parts hereinafter described and claimed.

In the drawings, Figure 1 is an end elevation of the valve with the filling-tube broken out; Fig. 2, a side elevation of the valve with the filling-tube broken out; Fig. 3, a. longitudinal sectional elevation of the valve with the filling-tube broken off; Fig. 4, a transverse sectional elevation showing the several passages for the admission of carbonic-acid gas or other medium, venting the pressure and admitting the liquid,with the controlling-plug turned to close all of the passages; Fig. 5, a

similar view to Fig. 4, showing the same passages, with the controllingplug turned to open the passage for the admission of carbonic-acid gas or other medium; Fig. 6, asimilar view to Fig. 4, showing the same passages, with the controlling-plug turned to shut on? the passage for admitting carbonic-acid gas or other medium and to open the vent-passage and the liquid-filling passage; Fig. 7, a transverse sectional elevation of the valve, showing the controlling-plug turned to shut off communication through the passage for admitting carbonic-acid gas and to open the vent-passage and liquid-supply passage and showing a modification of the means for establishing communication with the bottle for admitting carbonic-acid gas or other medium and venting the excess of pressure; Fig. 8, a

side elevation of the construction shown in Fig. 7; Fig. 9, across-section through the filling-tube and the neck of the closing-cap, showing the supply and vent passage of Fig. 7 for communication with the bottle; and Fig. 10, a longitudinal section in plan of the controlling-plug of Fig. 7, showing the passage for establishing communication with the bottle for admitting carbonic-acid gas or other medium and venting and equalizing the pressure.

The valve is constructed with a casing or shell A, having, as shown, a tapered. interior chamber or opening for the reception of a controlling-plug. The chamber or opening of the casing or shell at one end is closed by a cap or head B and at the other end is closed by a cap or head B. The casing or shell at one end has a projecting rim 0!, with an exterior screw-thread onto which is screw-threaded the rim 1) of the cap or head B, so as to make a close tight joint between the cap or head and the end face of the casing or shell. The opposite end of the casing or shell has a rim Ct with an exterior screwthread, onto which is screw-threaded the rim b of the cap or head B, so as to make a close tight joint between the cap or head and the end of the casing or shell, and, as shown, each cap or head has in its outer face a slot or recess 19 for the reception of a screw-driver or other suit-able instrument by means of which the caps or heads can be fully entered into place.

The casing or shell A has located in its chamber or opening a controlling-plug D for the admission of carbonic-acid gas or other medium, venting the excess of pressure and equalizing the pressure and admitting the liquid, which controlling-plug, as shown, is in the form of a tapered plug fitting the correspondingly-tapered chamber or opening of the casing or shell. The length of the controlling plug or valve is less than the full length of the chamber in which it is located, leaving a space in the arrangement shown between the end face of the controlling plug or valve and the closing cap or head B, in which is located a pressure-spring C, which spring seats in a recess therefor in the end of the controlling-plug and is of sufficient power to exert the necessary force for holding the valve pressed inwardly with the requisite frictional contact between the walls of the plug and the chamber of the casing or shell for holding the plug and the filling-tube against a return or falling back of the fillingtube when the controlling plug or valve is turned to shut off communication between the passages in the casing or shell and the passages in the controlling plug or valve, and the spring also serves the purpose of holding the plug-valve in its chamber so as to maintain a close fit and a tight joint against leakage around the controlling plug or valve.

The controlling plug or valve has transversely therethrough a hole or passage circular in cross-section and of difierent diametors. The smallest end of the hole or passage forms a port or opening d, and the adjoining section d of the hole or passage is screwthreaded at its end adjacent to the port or opening 61 to receive the end of a filling-tube, and the third section d adjoining the section d of the hole or passage, is of the largest diameter and has a screw-thread for the attachment of the closing-cap of the filling-tube. The filling-tube E at its inner end is screwthreaded and entered into the hole or passage of the controlling plug or valve to the end of the section d of the transverse hole or passage through the plug or valve, the screwthreads on the end of the filling-tube engaging the screw-threads of the section (1 of the hole or passage, and when in place the hole of the filling-tube will be in alinement with the port or passage (1 in the controlling-plug or plug-valve, as shown in Figs. 3, 4, 5, 6, and 7. The filling-tube is of a length to extend into the bottle a sufficient distance for the filling operation, and, as shown, the exterior end of the filling-tube has on one or more sides a discharge port or opening e, which when the filling-tube is inserted in the bottle allows of the discharge of the liquid into the bottle. The filling-tube, as shown, has in its interior a venting-pipe F, which at one end is in communication with a port or openingf through the wall of the filling-tube and at its other end is in communication with a port or opening f in the wall of the filling-tube, and this pipe F serves the purpose in the construction shown in Figs. 1 to 6, both inclusive, of admitting carbonic-acid gas or other medium into the bottle and of venting excess of pressure to equalize the pressure in the bottle and the liquid containing or filling tank or receptacle for admitting the liquid to the bottle in the condition of equal pressure in the bottle and in the tank or receptacle.

The body of the filling-tube above the port or opening f is encircled by a closing-cap G, which has a neck G with an exterior screwthread to enter the screw-threaded section 01 of the transverse hole or passage through the controlling plug or valve, and the neck G passes through an elongated slot or opening g in the casing or shell of the valve, which slot or opening is of sufficient length to allow the necessary turning of the controlling plug or valve to shut off and admit the carbonicacid gas or other medium and to close and open the passages for venting the excess of pressure and admitting the liquid to the bottle. The closing-cap, as shown, is of a semicircular shape and at its outer open end has an inwardly-extending rim or flange g, against which abuts the lower edge face of a packing or cushion H, of rubber or other suitable material, and, as shown in Fig. 3, the packing or cushion has a central conical depending closure or stopper h, through which the filling-tube passes and which when the fillingtube is in the neck of the bottle-enters the mouth of the bottle and, in connection with the packing or cushion H, tightly closes the mouth of the bottle against escape of the gas or other medium, the pressure, and the liquid when the end of the bottle neck is held tightly against the packing or cushion H of the closing-cap.

The controlling plug or valve has an annular or circular passage or chamber 0 encircling the body of the filling tube and into which leads the port or opening f of the supply and vent tube F. The casing or shell A on its front side in the construction shown has entered a T-coupling, having its crossarms I screw-threaded on the exterior for the attachment of a hose or other tube or pipe and having its stem I screw-threaded into a boss 1? on the casing or shell. The stem I has a passage 1 which is in communication with a port 2 in the casing or shell and extends through the arms of the T-coupling and receives a plug-valve Ifl'by means of which communication is established between the passage of either arm of the coupling and the passage i of the stem of the coupling. The coup' lingis to be connected by asuitable hose, tube, or pipe with a source of carbonic-acid gas or other medium that is to be injected into the bottle prior to the filling of the bottle with the liquid. The body of the controlling plug or valve D has leading from the passage or chamber c a passage i which can be brought into communication with the port 2', allowing the carbonic-acid gas or other medium to How from the source of supply into the chamber or passage cand enter the supply and vent tube F to discharge therefrom through the port f into the bottle; and, as shown, in order to give an increased period of time for communication between the port i and the passage 1' the port on one side is elongated, so that the carbonicacid gas or other medium will flow into the bottle until the end of the elongation oi? the port is passed by the end of the passage 2' with the turning of the controlling plug or valve to bring the bottle into its filling position. The casing or shell A on its upper side in the construction shown has a neck A with a screw-thread on its exterior, and adjacent to the neck is a flange or rim a and on the rear side of the casing is an extension A for the attachment of a bottleholder. (Not shown.) The casing or shell A and the neck A have therein a passagej for the admission of the liquid, which passage when the controlling plug or valve is turned to bring the bottle and the filling-tube into a filling position for the bottle alines with the port cl, allowing the liquid to enter the filling-tube and discharge into the bottle. The plug-valve has therein a passage is, which is in communication at its inner end with the annular passage or chamber 0 around the body of the filling-tube, and this passage when the controlling plug-valve is turned to establish liquid communication alines with a passage 75 in the casing or shell A and the neck A, into which passage is entered the end of a vent-tube which is in communication with the tank or receptacle containing the liquid. The passages (l, 71 and k in the controlling plug or valve in their relation to each other and to the passage j, port 1', and

passage is in the casing or shell is such that when the plug-valve is turned into the posi valve will be out of alineme'nt with their coacting port and passages in the casing or shell, and with the controlling plug-valve in the position shown in Fig. 4: the bottle is to be entered on the filling-tube. The initial turning of the plug-valve to bring the bottle into the filling position opens communication between the port vi and the passage 6 for the carbonicacid gas or other medium to enter the tube F and discharge into the bottle, filling the bottle with carbonic-acid gas or other medium under an excess of pressure, and the admission of carbonic-acid gas or other medium into the bottle continues until the end of the passage 2' passes the end of the port 2', shutting off communication. The continued turning of the plug-valve to bring the bottle into its vertical filling position when the fill-.

ing position is reached establishes communication hetween the passage j and the port 61 and at the same time establishes communication between the passage 7.4 and the passage 7c, with the result that the excess of pressure for the carbonic-acid gas or other medium in the bottle over the pressure in the filling tank or receptacle is vented through the tube F into the chamber orpassagecand out through the passages 75 7c and tube 7: into thefilling tank or receptacle, and when an equilibrium of pressure is established between the interior ot the bottle and the filling tank or re ceptacle the liquid, which has been held back by the excess of pressure in the bottle, is free to how by gravity into the filling-tube E and discharge into the bottle under the condition of pressure, with the result that the liquid thus entered into the bottle will force out the pressure in the bottle, so that the liquid will be discharged intothe bottle under a uniform pressure in the bottle and tank or receptacle,

by which foaming is prevented and the bots tling operation is performed without waste of the liquid and without deterioration in the quality of the liquid.

The medium employed for first charging the bottle is, preferably, carbonic-acid gas, which acts to kill all of the air-germs inthe bottle and by its coolness effects a cooling of the bottle, so that the liquid will be discharged into the bottle with the air-germs, if any, in the bottle killed and the bottle in a cool condition, which is desirable in bottling liquids. The carbonic-acid gas will also serve to charge the liquid to the extent that such gas is absorbed by the liquid, thus giving an aerated condition or quality for the liquid. The carbonic-acid gas is discharged into the bottle under an excess of pressure as compared with the pressure in the tank or receptacle containing the liquid, and this excess of pressureuntil it is equalized acts as a shut-cit or closure against'the admission of the liquid, giving the carbonic,acid gas the necessary time for killing the air-germs and effecting a cooling of thebottle, and with the reduction of the'pressure in the bottle of the carbonicacid gas an equalization of the pressure in the bottle and the liquid tank or receptacle is attained, whereby the filling of the bottle with the liquid is positively assured under the condition of an equal and uniform pressure, thus insuring the bottling of the liquid under the requisite conditions for the best results. The medium initially discharged into the bottie could be compressed air,for instance,which would effect a cooling of the bottle, but would not kill the air-germs, and it is to be understood that the medium employed can be any suitable medium which will give an excess of pressure in the bottle that will be equalized with the pressure in the liquid tank or receptacle when the vent-passage is open, so as to insure the filling of the bottles under a uniform and steady pressure between the interior of the bottle and the tank or receptacle. The admission of the excess of pressure medium into the bottle and the venting thereof from the bottle can be otherwise than by means of the supply and vent tube F, and, as shown in Figs. 7 to 10, both inclusive, the neck of the closing-cap has therethrough a passage Z around the filling-tube E, which passage communicates with a passage 1 in the controlling plug-valve leading into the annular chamber or passage 0, so that communication is established between the chamber or passage 0 and the interior of the bott-le through the passages Z and l, by which the carbonic-acid gas or other medium can enter the bottle when the port I: and the passage are in communication, and the excess of pressure can be vented from the bottle when the passages 76 and 7c are in communication.

The valve of the present invention enables carbonic-acid gas or other medium for killing the air-germs and cooling the bottle to be supplied to the bottle under an excess of pressure, and the excess of pressure acts as a cut off against the admission of liquid until the pressure is equalized between the interior of the bottle and the filling-tank, thus insuring the admission of the liquid to the bottle under an equalized pressure and also when carbonic-acid gas is used, insuring the charging of the liquid with the gas, which is desirable for aerated liquids, and whether carbonicacid gas or other medium is employed under an excess of pressure the result will be the cooling of the bottle, which is desirable in the bottling of liquids.
