FILLING-MACHINE.

Application filed October 29, 1914. Serial No. 869,344.,

To all whom it may concern: 1

Be it knownthat I, PHILIPVJ. SAULsoN, a citizen of the United States, residing in the borough of Manhattan ofthe city of New York, in the county of New York, j

the State. of New York,have invented certain new and useful Improvements inFill ing-Machines, of which the following is a specification,'referencebeing had to the accompanying drawings, which form a part hereof.

This invention relates to machines for fill with any liquid, whether charged with'gas contact WlthtltlllOSPllGllC air.

"lhe improved machine is designed espe cially for the filling, with a gas charged liquid, such as beer or any other foaming beverage, siphons or similar receptacles in whichliquid is kept under pressure of carbonic acid gas. It is designed especiallyfor,

the filling of receptacles of this character valves which permit the escape of gas when the pressure exceeds a predetermined degree but otherwise act to retain the liquid under a pressure lower than that at, which the vents open. i r '1 One object of the invention is to enable the filling of such receptacles to be carried on rapidly and automatically, that is, without further attention on the part of the attendant than that involved in the re-v placing of filled receptacles by ceptacles.

Another object is to permit the filling to be carried on at all times under gas pressure and without danger of contamination of the liquid by contact with atmospheric air. I 1 I Still another object is to permit a measured quantity of liquid to be introduced into each receptacle regardless of its greater capacity. p r

it is also an object to provide for theintroduction into each receptacle of a measempty reured quantity of syrup or extract to be.

mixed in the receptacle with the main body of the liquid with which it is filled.

Other objects and accomplishments of the invention will appear as this description proceeds.

comprising a liquid container a provided in the accomdesigned to be filled through the discharge nozzle the valve a being then held open, while the displaced air or gas is discharged through the safety valve or vent a. Y Such a vessel to be filled is placed upon a support 6 carried by a bracket arm 7) which-is secured to the frame B of the machine and the discharge nozzle a is adapted to enter and fit snugly in the terminal 0* of a filling pipe hereinafter referred to, such terminal being provided with suitable packing devices for the purpose of making a tight joint. In the machine shown inFi'gs. 1-5 the horizontal portion of the discharge pipe a a serves to hold a portion of the mechanism in position for filling as hereinafter explained, themovement of such part to filling position being eifected directly by the handof the operator or by the placing of the siphon in position to be filled.

The beer or other liquid to be bottled may be supplied from any suitable source, such as the barrel or keg indicated (though not in true relative size) at C in Fig. 5. The gas under pressure of which the operation is carried on, may also be supplied from any suitable source such as the ordinary cominercial carbonic acid gas cylinder C, the flow of gas being controlled by suitable ducing valves 0 and 0. The gas, at reduced pressure, is admitted through a pipe c to the closed supply vessel C and under its pressure the liquid is discharged through. a pipe 0 0 provided withsuitable stop cocks, to the filling machine- Preferably the liquid enters first a foamseparating and equalizing chamber 0 which is common to all of the filling heads of a machine which may comprise many separate filling heads but is shown in the drawings as having only one. From the equalizing chamber 6 the liquid is conducted through a pipe 6 a valve D, the construction of which will be explained, one member of a- T-connection 0 to a pipe a to the measuring vessel E, the details of which will be described, The measured quantity of liquid received in the measuring vessel E is discharged therefrom under gas pressure, as hereinafter described, through the pipe 0 and the other member of the T- connection 0 and through a valve D", the construction of which will be explained, to the discharge pipe 0*, and its terminal 6*, It Will be understood that when the valve D is ling valve G to the measuring vessel E. The

gas displaced from the measuring vessel by the incoming liquid, is conducted through a pipe 0 a gas valve F, the construction of which is similar to that of the valve F, and a pipe 0 to the filling terminal. 0* from which it enters the receptacle A, preceding the liquid. The valves l F are controlled,

as hereinafter explained, so that they open in alternation and in proper relation to the opening of the valves 1) and l). The regulating valve G is suitably constructed, as

shown in detail in Fig. 4i, so as to permit the gas to enter the measuring vessel E slowly, in order to prevent the liquid from being driven out of the measuring vessel too violently. As shown in Fig. 4: this regulating valve comprises an ordinary needle valve 9 provided with a hand wheel. 9 by means of which the valve can be regulated closely.

The two valves D and D may be identical in construction and a description of one will therefore suifice for both. As shown in Fig. 7 the valve D may comprise a block (Z having also a passage a with which the pipe communicates and a valve seat (5 and having also a passage d with which the pipe communicates, such passage terminating in an annular groove (I around the valve seat (Z A diaphragm valve (Z held in place by a cap d, is pressed normally by a springpressed plunger (Z against the valve seat (P, so that normally the passage through the valve is closed. The valve is opened at the proper time by means to be described.

The valves F and F are also identical in construction and a description of one will sufiice for both. The construction is substantially like that of the valves l) and DT. The valve block f is provided with a central bore f which communicates with the pipe 0 and has at its upper end a valve seat F. It is also provided with a passage f which communicates at its lower end with a pipe 0 and at its upper end with an annular groove f which surrounds the valve seat F. A diaphragm valve held in place by a cap 7, is pressed normally by a spring-pressed plunger 7" against the valve seat f to close the passage through the valve. The valve is opened at the proper time by means to be described.

The measuring vessel E, which is preferably employed, comprises a tank 6 of suitable capacity which is mounted on the frame B of the machine and is connected through the pipe 0 and the valve 1) with the supply llll vessel C and through the pipe 0 and the valve D with the filling terminal 0*," as shown in Fig. 1 it is provided at its lower end, at the point of' connection with the pipe 0 with a valve seat 6 which is closed, when the vessel 6 is empty,'by a valve 6 whiclris 'carriedby a float 6 So long as there is any appreciable quantity of liquid in the vessel e the float 6 holds the valve from its seat so that the inflow and outflow of liquid may take place, but when the vessel e is empty of liquid the valve e rests on its seat so as to prevent the outflow of gas.

In the vessel. 6 is a float e which, through suitable intermediate. mechanism, such as that about to be described, controls the liquid and gas valves D D and FF, as explained hereinafter. The stem 6 of the float is connected, by a pin and slot connection 0, with a lever e pivotally mounted on a plate 6 wh1ch is secured to a standard 6 on the top of the vessel 6. The lever e is connected by a link 6 with a lever e machine, and held, down thereby, as indi-.

rated in Figs. 1 and 5. The lever or frame a is secured to the short shaft k which is mounted in suitable bearings k and has secured thereto a weighted arm h by which he lever is held normally but yieldingly with its forward end elevated. I The shaft [-1. has secured thereto a hook k which en gages, when the parts are in the filling position, a pin 71 carried by an arm-71 of a shaft 5 Another arm 2' at one end of the shaft is pivotally connected with alink i forming therewith a toggle lever. The link. i is pivotally connected with a forked lever which is pivotally mounted on a standard 2 and underlies the cross-head d of the plunger (Z of the valve D. The arm 6 is also oivotallv connected by a link i (forming therewith a toggle) with a forkedlever-e' which is pivoted on a standard 2' and unilerlies the cross-head (Z of the plunger'cl if the valve D. A similar arm 2", near the ther end of the shaft 2' tseeFig. 3), is-

;imilarlv connected by a link 7: with a forked lever 2' which underlies a crossghead on the plunger f of the valve F, and, is.

also connected by a link 1 with a forked lever 77*, which underlies the. cross-head f of the valve F 7 A third arm 11 on the shaft i is connected to the plunger is (see igs. and -16.). f a. dash-pot. Kwlliclg;

is suitably supported on the frame "A spring /c, within the cylinder of the dashpot, acts upon the plunger is to move the I connected parts, when they'are released by the hook 72, from thepositions shown by full lines in Fig-16' to-the positions shown by-dotted lines. When the parts are in the positions shown by full lines the-valves D and F are'held. open'against the tendency of the 'spring pressed plungers d to close them and the valves D and F are per mitted to be closed by their spring-pressed phingers; When the hook k is disengaged from the arm '11 and the spring 70 is per mitted to act the valves Dand- F are permitted to be'closed by their spring-pressed plungers and the "valves D I and F are opened. The disengagement ofthe hook :h is effected, when the measured quantity of liquid has, beenintroduced into the mease uring vessel E, by the lift of the float e to,

its highest position, such lost movement in the connections being providedfor as causes the float toactas itreaches' the limit of its.

upward movement.- It' is ofcourse possible toevary the quantity of llqlllCl which'causes the float to act through ad ustment of the connecting links inan obvious manner. As] soon as'thesiphon is removed from the fill,

ingposition the weighted arm it causes the it. the shaft H, so that the-ho0kh rises into positiontjo engage and does at 'once engage again thepln i of the arm 71-. so that when the forwardend of the lever it is pressed The operation of theaparticular embodiment of the invention thus fardescribed will frame 7t to be swung upward, carrying with now be understood readily by reference to Fig. 5 VVhenthe siphon is placed in position to be filled the lever k is swungdownward, carrying the connected parts into the positions shown in Fig. 16, in which the valves D and F are opened and the valves D and F are closed.v Under the pressure of the gas in the supply vessel C, the liquid thereintherefore flows through the pipes 0 the foam separating and equalizing vessel 0 the pipe cf',-the valve'D and the pipec v into themeasuring'vessel E. The gas (or, in the first 'OperatiQmthe-air) which is displaced by the. liquid which enters the measuring vessel E, is forced out through the pipe 0 V the valve F and the pipe 0 into the siphon A, displacing therein the air (or gas) with which the siphon was previously filled, such air (or gas) escaping through the safety valve a. As soon as the predetermined quantity ofliquid has entered the measuring vess l E and. the float-ethas reachedits highest point, the latch if is disengaged from the arm 2" and the spring is is permitted to shift the connected links from the positions shown by the full lines in Fig. 16 to the positions shown by dotted lines therein, thus closing the valve D so as to stop the further flow of liquid into the measuring vessel, and also closing the valve 15 so as to prevent the further escape of gas from the top of the measuring vessel E. At the same time the valve F is opened, wlnch permits gas to fiow from the gas supplied through the pipe 0 and the pipe 0 into the top of the measuring vessel E and the valve D is openedso as to permit the measured quantity of liquid in successive operations, if the machine is not opened to atmospheric air, the liquid at no timecomes in contact with atmospheric air, either in the measuring vessel or in the siphon itself, since at each operation the gas in the upper part" of the measuring vessel E precedes the liquid into the siphon'and, entering the same at the bottom it being heavier than air, drives the air therein out through the safety valve or vent a.

As soon as the measured quantity of liquid has been driven out of the measuring vessel into the siphon, the outlet of the measuring vessel is closed by the valve 6 thereby stopping the further movement, either of gas or of air, and the machine then remains in its then condition until the filled siphon is removed and the hook if is permitted to rise into engagement with the arm 71 so that the parts are in position for the institution of another operation of filling as soon as the lever A is pressed down either'by the hand of the operator or the application of the empty siphon to be filled.

Ttwill be obvious that various changes in details of construction and arrangement can be made to suit different conditions of use. Thus, in place of valves D' D F F of the type shown in detail in Figs. 7 and 8, there may be substituted rotary valves such as are shown in detail in Figs. 9, 10 and 11 and are shown in relation to the other parts of the machine in Fig. 12. In this construction the two valves D and D are replaced by a single rotary valve D and the valves F and F are replaced by a single rotary valve F Both of the valves 1) and F may be mounted upon the shaft 6 mounted in suitable bearings on the main frame and provided with an arm i for engagement with the" latch 71. and provided also with an arm i for engagement with the piston 76 of the dash-pot K, all substantially as already described. The shaft 71 may also be provided with a handle 2' for manipulation by the operator. The latch 71/ in this construction, is pivoted in fixed bearings 72 and the arm 6 is connected directly thereto, The arm 6 has a finger 0 which overlies the arm 0 connected to the float through the link 6 The parts referred to and their connections are shown clearly in Figs. 9, l2 and 18 and operate substantially as already described.

The valves themselves, 13* and F will now be described. The two valves are identical in construction and a description of the de tailsof construction of one will answer for both. Mounted loosely on the shaft 2' and supported in a fixed position by brackets (13* is a valve body which comprises a central body 6 chambered at its ends as at d and (l and having threaded on each end a corresponding cap cl and vc The central body is provided with a passage cl which afiords communication, always open, between the pipe a and the chamber d; with a passage (Z which affords communication between the pipe and the chamber d; with a passage (Z which affords communication between the chamber (l and the pipe 0 when .the end of the passage 5Z is uncovered; and

with a passage cl which affords communication between the two chambers cZ and d when its ends are uncovered. Against the opposite faces of the central body d bear two valve disks 6Z which are keyed to the shaft 2' so as to move therewith and may be pressed against the corresponding faces of the central body by springs al Each of the valve disks (Z 'is provided also with a port cl? adapted to register with the passage d through the central body d Since the passage (Z is always open, the liquid from the supply vessel C may always flow to the chamber d. When the parts are inthe filling positions, as indicated in Fig. 18, with the arm 2' engaged by the hook it and held against the tendency of the spring in the dash-pot K to give the shaft a partial rotation clock-wise, the ports (P2X of the disks al register with the passage d so that the liquid may then flow from the chamber (Z through the passage (Z into the chamber 6 3X and thence into the pipe 0 and the measuring vessel E. hen the hook k is disengaged from the arm i the spring in the dash-pot gives the shaft a partial rotation clock-wise which moves the port (Z of one disk J 9 into registration with the passage 6Z thereby. placing the measuring vessel E in communication through the" pipe 0 the chamber cl and the passage 6 in communication with the pipe 0 and its di's'charge'terminal 0*, whereby the liquid in the measuring vessel-may then be the measuring vessel when the liquid is being discharged from the measuring vessel mto the siphon. It is unnecessary to enter into a detailed description of the valve audits connections so far as the operation oi the gas valve without the addition ofa syrup or extract adding device is concerned.

The machine shown in Fig. 12 is provided with a device for adding syrup or extract and while in such machine the rotary liquid valve D is constructed and connected as just described, the rotary gas valve F has a special construction to suit the requirements of the case, suchspecial construction being shown in Figs. 13 and 1d while the connections are shown clearly in'Fig. 12. The

1 syrup or extract is supplied from any suitable source through a pipe m to a measuring vessel M, suitably supported on the frame of the machine, asindicated in Fig. 12. As shown Fig. 15 the 'measuring vessel M comprises preferably a central portion m of glass and-end caps m and m of metal. Adjustably suspended within the measuring vessel, by means of a lever m pivoted in the upper cap of, and a threaded rodmfi, is a float m, Also supported by the upper cap m is a vent valve m. The syrup or extract is admitted to and discharged from the vessel M through the connection m atthe bottom and a valve N which is controlled by the partial rotation of the shafte'. The

construction or the valve N may beidentical' with that ofthe valve l), as shown in detail in Figs. 9, 10 and 11, and therefore "need not be further described herein. l/Vhenthe valve is in one position the liquid is permitted to flow from the pipe mintothe vessel M through the connection m and when the valve is 1n another =POS1t1OI1 the liquid is permitted to flow from'the vessel M through the pipe n to and through the filling terminal 0*- into the siphon in advance of the flow of the main body of the liquid from the measuring vessel E into 'the'siphon, such precedence offiow of the syrup or extract not only permitting a thorough mixture of the main body of-the liquid therewith tobe effected as the-main body of the liquid enters the siphon in the bottom. of

which the syrup or extract already stands, but causing the syrup :or extract,- which is usually more or less sticky, to be washed out thoroughly from the filling" terminal c"..

The flow of the syrupor extract from 'the measuring vessel M is efiected under gas a is chambered at'its ends, as at f and pressure, the .gas bein'guadmitted to the top" of the measuring vessel M by a pipe m from p the gas valve F Because of the conducting ofthe gas from the gas valveF- to the vessel M the'constru ction of; the valve F when the device for adding syrup or. extract is added to the machine, isslightlydiilerent from that which answers the purpose when such device isfnot employed. The construction of such modified form of the gas valve F is clearly shown in Figs. l3and 14, the connections being shown inFig. 12. The central body 7', supported in fixed position by brackets f and-receivingloosely the shaft f and receives at itsends threaded caps f fand A passage 7 in the central body f? afiords communication between the gas (supply) pipe 0 and chamber 7 (see Figs. 5 and 12). A passage 7? aiiords communication. between thechainber f and the gas supply pipecu passage fi affords com.-

munication between the chamber f and the pipe m by which the gas is conducted at the proper time to the top; of the syrup vessel M. A passage f affords communication between the pipe 0 and the chamber. fP so thatthe' gas displaced in the-measuring vessel E may be delivered to the measuring vessel M to drive out the syrup or extract therein. f I

Valvedisks F95, held by springs f against'the corresp ondingfaces of the central body f and each provided with a port 7 f for cooperation alternately with'the passages. f? and f, respectively, are keyed on the shaft '5 and the passages and ports are so positioned relatively'to each other and to the ports and passages of the valves D?" and N that operations take placeas follows:

,. The liquid is first admitted'to the measuringvessellE and the displaced air. or gas therein is driven through the pipe 0 the k ing vessel ,M. ,Theavalve N'at this time is in such'position as to open communication between the measuring-vessel. M and the filling terminal 0*, so that the-"gas displaced from the measuring'vessel E-"and entering the measuring vessel M drives out the syrup or extract "from the measuring vessel M.

through the valve and pipen into the siphon. When the predetermined quantity of liquid has entered the vessel E the'float e 'through the" connections 6 e and 6 shown in Fig. 1, and'the connections 6. 8

and 5 shown in Fig. 18, disengages the hook b from-the arm al and 'premits the shaft 2' to receive a partial rotation clockwise under the influence of the spring 7 of parts the valve D opens: communication between the measuring vessel E and. the fill-' ingterminal 0 thevalv'e F opens communication between the gas conductor 0 and valve f and the pipem" .into the measurthe dash-pot K. In the new. position of the i the measuring vessel E andcloses communication between the return pipe 0 and the pipe m leading into the measuring vessel M, thereby cutting otl the gas pressure from the vessel M and permitting the vent valve m to open, and the valve N cuts off communication between the measuring vessel M and the filling terminal 0* and opens com munication between the syrup pipe on and the measuring vessel IVI, thereby permitting the syrup or extract/to enter the vessel M until the flow is cut off by the action of the float m inclosing the vent valve m In these positions of the parts the liquid from the measuring vessel E flows into the siphon, washing out all of the syrup or extract from the filling terminal 0* and making a thorough mixture with the syrup or extract in the siphon. The flow of the liquid ceases, as before, as soon as the vessel E is emptied and the parts remain in the positions then occupied until the attendant removes the filled siphon and replaces it with an empty siphon, at which time, grasping the handle i, he restores the shaft 91 against the action of the spring is of the dash pot K, to its initial position in which it is held by .re'engagem'ent of the latch 72. with the arm 2'. The successive operations are then repeated in the same way as before.

It will be seen that in each of the several constructions shown the flow of liquid to the receptacle to be filled will be cut off automatically through the action lot the spring in the dashpot when the predetermined quantity of liquid has beenv introduced into the receptacle and that in the form oi the machine shown in Figs. 1-5 the flow of liquid through-the filling pipe will also "be cut oil automatically, through the action of the spring in the dash-pot, whenever the siphon is :removed from the machine so that there will then be :no waste,

either of gas or liquid.

It .will. be understoodthat various other modifications and changes in details of construction and arrangement, as required by different conditions of use,-may be made without departing from the spirit of the invention, which -is not limited to any particular construction and arrangement of parts.
