Referring to the drawings, 1 designates a liquid tank which is mounted to revolve on a hollow pedestal or stand Qvof any suitable construction. The pedestal is provided wit-h a ball bearing 3 on whichthe tank rests and the tank has a hollow boss 4 projecting downward from its bottoni to fit in the upper end of the pedestal. The liquid inlet pipe 5 is arranged in the pedestal and is provided Iat, its lower end with one or more branches 5 to which a hose leading from the liquid 'supply is connected. This liquid pipe 5 extends up through the boss 4 into the tank 1 and a nut G is screwed on its upper end. A collar 7 ancha washer 8 are arranged on the liquid pipe beneath the nut (S and in a recess 9 in the bottom of the tank upon an annular shoulder 10 at the top of the boss 4: (Fig. 2). A. spring 11 is arranged on the liquid pipe between a fixed part .2 of the pedestal and a shoulder 11 on the pipe, and this spring by expansion pulls down on the upper end of the liquid pipe and holds the nut 6, collar 7 and washer 8 tightly together with the washer bearing on the shoulder 10 to prevent the escape of liquid from the tank, but at the same time permitting the tank to revolve on th liquid pipe.

The lid 12 of the tank is secured thereon in an air tight manner by suitable fastening devices. The air tube 13 enters the tank through the lid and is provided with a pressure gage 14, a pressure regulator 15 and a stop cock 1G. f

A fioat valve 17 is arranged in the tank and it has an outlet opening 17 in the loottom of the tank to permit the escape of gas from the tank when the liquid in the tank falls below a predetermined level. I may use any form of valve suitable for this purpose but l have shown in the drawings the valve covered by my Patent No. 883,254 dated March 231, 1908. As this valve forms no part of the present invention it will not be necessary to enter into a detail description thereof. The purpose of this valve is simply to maintain the liquid at a predetermined level by allowing the escape of gas from the tank, when the liquid in the tank falls below the predetermined level, to permit the liquid to fiow into `the tank from the supply.

The tank is preferably circular in form and is provided with a plurality of filling mechanisms supported in its side and spaced vapart in convenient position. Each filling mechanism comprises a casing 18 which is arrangedin an opening 19 in the side of the tank and has an annular flange 20 at its inner end to engage the inner face of the side of the tank, there being, preferably, a washer 20 located between said flange and the tank, as shown in Fig. 3, to form a tight joint.

A clamping ring 21 screw-threaded on a threaded portion`"of the casing secures the casing to the side of the tank. A rotatably movable plug 22 is arranged to rock in the easing 18 and is bored transversely to receive the tubular plug section 23 of the filling tube which is bent in angular form. (Fig. 3). This plug section of the filling tube carries a nozzle section 24 at its outer front end tof/enter the bottle, and a valve section 25 atI its rear end within the tank, and the bores of the three sections form a continuous and uninterrupted passage for the liquid. I prefer to make the filling tube in sections as described for convenience in the manufacture and assembling of parts, for strength at the rock plug, and to facilitate cleansing and repairs. The filling tube projects downwardly and outwardly from the tank and is preferably closed at its lower end and provided with a discharge opening 24 on its upper side at or adjacent to its lower outer end. A sealing head 26 is car' ried on the outer end of the plug section -o and is provided with a rubber seat 2G to receive the mouth of the bottle. A supporting arm 27 is connected to the sealing head and it carries a bottle rest 2S adjustable longitudinally of the arm and secured in position by a set screw 23. The plug sec tion 23 of the filling tube has a shoulder 23 which abiits against the plug 22 and this section has one or more longitudinal bores 29 forming an air passage from the sealing head to the plug and there connecting with grooves 30 cut in the inner face of the plug section and forming a continuation of the air passage. Grooves 30 are disposed longi tudinally of the plug section 23 so as to register with the bores 29. Communicationis established between the various bores 29 through an annular groove 30 connecting the ends of the grooves 29.

A tubular aii valve member 31 is secured on the plug section 23 within the tank by a nut 32 screw-threaded on the rear end of the plug section. By adjusting nut 32 the shoulder 23 and the front -end 31 of the air valve member are clamped tightly against the plug to form air tight joints, and washers may be used in said joints if found desirable.` The air valve membenhas an upwardly inclined branch 33 provided with a bore 34- which communicates. with the groove 30 and forms a continuation of the air passage. Communication is established between the liquid tube in the plug l' section 23 and the air valve through an it otherwise would be if the bores were de-y pended upon solely for the passage of the gas.

All air valve adapted to be automatically operated as the filling tube is moved to filling position is piovided in the air passage and this valve is preferably made as illustrated in Fig. 3. The branch 33, in this construction, comprises, for convenience, a tube 33 which is screw-threaded in a tubular boss 33 and is provided with a head 35 andone or more lateral ports 34 beneath the head. A sleeve or collar 36 is arranged on the tube 33 `and it has a seat 3G at its upper end for the head 37. Links 3S are pivotally connected to the sleeve 36 and to a fixed point, preferably an arm 39, on the casing within the tank. Then the nozzle end of the filling tube is swniig downward sleeve and a collar 43 at the inner end of4 the filling tube. The spring normally yholds the valve seated against thel inner end of the filling tube but when the parts are swung at the rock plug the upper end of the sleeve l() will engage the bifurcated end 39 of the arm 30 and the valve will be unseated to permit the liquid in the tank to flow through the filling tube into the bottle.

The bottle is clamped against the sealing head by engagement with a pair of curved clamping arms 44,45, (Figs. 8-10) which are pivotally supported on the tank below the easing 18. In the construction shown iii the drawings one of' the arms 4l s'bored and also provided with a laterally extending sleeve 4-6 to receive a shaft 47 and the other arm. 45, is mounted on the sleeve 46. An ear 4S on the tank is bored to receive the sleeve 4G and the arms are located on opposite sides of thisl ear and are connected by a spring 49 attached to lugs 49 on the arms (Fig. 10). Thus the arms are capable of a pivotal movement and also a movement towardv and from cach othei'. Spring plates 5() (Fig. 8) are fastened to the tank and are engaged by the upper lugs 51 and the lower lugs 52 on the arms. The lug 51 engages the spring plate adjacentl to its fast end and limits t-he upward movement of the clamping arm. The lug 52' engages the spring plate nea-r its lower free end and yieldmgly retards vthe tendency ofthe clamping arm to swing downward under the pressure of the bottle, as hereafter described. A stop 53 on one arm, as 44, limits the downward or inward swinging movement of the bottle and the filling tube to filling position.

The construction and arrangement of parts hereinbefore described is one which I have found well adapted for embodying my invention in` a machine for filling beer and the operation thereof is as follows: The lid having been secured on the tank and the liquid pipe and the air pipe being .connected to the source of supply the required pressure is first established in the tank and then the beer is forced into the tank against the pressure therein. A bottle 54, shown in broken lines in Fig. 3, is pushed up on the filling tube -against the sealing head and rested against the rest 2S. The outer ends 44', 45', of the clamping arms (Fig. 9) are ared or turned outwardly to permitthe bottle to be engaged with the sealing hea-d as just described. Then downward pressure is applied on the bottle to swing the filling tube and the parts connected therewith at the rock plug. This movement will rock the plug and swing the bottle downward and toward the pedestal and the shoulder 54 on the bottle will engage the upper faces 44, 45 of the clamping arms which are curved eccentrically from the rock plug as a center to form cams on which the shoulder travels to force the mouth of the bottle tightly against the seat 2G in the sealing head. As the bottle begins its downward movement and is fairly seated the air valve is opened to permit an equalization of pressure in the bottle andthe tank before the filling valve is opened; and by the time the bottle has reached filling position againstthe stop 53 the filling valve. is opened to permit the beer to flow into the bottle. The tank is then swung on the pedestal and a bottle applied to the next filling tube'and so on until the first bottle comes around to the operator. lly this time the first bottle is filled and the operator removes it from the machine and replaces it with an empty bottle in the manner heretofore described. The pressure applied on the bottle to move it downward is directed against the rest QS and in swinging the bottle upward the operator grasps the bottle and the rest or the supporting arm 2T so that there is no liability of breaking the bottle at the neck. The spring 49 permits the clamping arms to yield laterally during the swinging movement of the bottle and enables these arms to automatically adjust themselves to inequalities in the bottles. The spring plate 50, as previously described,

yieldingly limits the downward swinging movement of the clamping arms and also en. ables said arms to automatically adjustthemselves to inequalities in the bottles. When the bottle has been filled and is swung upward to removal position the beer Valve and the air valve are automatically closed;

In the construction shown in Figs. 1-10 the air passage is formed partly by bores and grooves in the filling tube and I have found this to be a very satisfactory-method of construction, particularly for the reason that it makes the tube stronger just in front of the rock plug where the greatest strain occurs. This construction also has o ther advantages from a manufacturing standpoint which it is not necessary to refer to in more detail. In Figs. 11 and 12 I have shown another construction in which an air tube 55 projects through the rock plug 56 and carries on its outer end a sealing head 57 and onits inner end a valve member 58. The air tube has a collar 59 rigid therewith to engage the front of the plugand the end 58 ofthe member 58 is clamped against the rear of the plug when said member is screwed on to the air tubev55. The filling tube 60 is supported in the rear end 61 of the member 58, the latter forming a continuation of the air tube 55. In this construction the air passage is located between the tubes 55 and 60, these tubes being independent of each other and bent in a similar manner to fit one within the other with suflicient space therebetween to permit the passage of air in the desired manner. In this construction the air passage extends from the sealing head alongside of the liquid passage, lbut separate therefrom, to the air Valve within the tank just the same as shown in the construction of Fig. 3 but with the difference, as heretofore mentioned, that it is formed by the space between two tubes one arranged within the other instead of by boring and grooving a single tube, as shown in Fig.` 3. These two constructions are, it is believed, the substantial equivalent one for the other but from a practical standpoint the construction shown in Fig. 3 is to be preferred. Inother respects than those specifically described the construction of Figs. 11 and 1'2 is 'substantially the same as that of Fig. 3.

In Figs. 13 and 14 I have shown an air lvalve of a somewhat different construction from that shown in the other figures of the drawings. Referring to these figures, the branch air tube 62 is provided with a valve casing (33 having an enlarged port 63. A valve plug 64. is arranged in the casing ($3 and it has a transverse port. G5 which is enla rged at one end G5. in arm 66 is fastened to the valve plug and is connected by a link 6T to a fixed part GS on the valve casing 1S. It will be readily understood that when the filling tube is swung downward, as heretofore` described,l the link 67, pulling on arm 66, will turn the valve plug until the port 65 registers with the air passage 62 toestablish communication between the link and the 5 bottle, and that when the filling tube is moved upward to normal posit-ion, the valve plug will be turned backward to close the port 65 as shown in Fig.`14. The enlargement 65 of the port 65 is provided so that the air valve will open communication between the tank and bot-tle before the liquid valve is opened. This valve can be used with the construction shown in Fig. 3 or with tha shown in Fig. 11. l

The invention` is simple in construction and rovides a hand machine :for filling liqui s which can be easily operated and at considerable speed. The machine is particularly adapted for filling liquids charged with gas, such as beer, and it maintains a pressure on the beer in the tank to prevent t-he escape ofv gas from the beer and provides for equalizing the pressure in the bottle and the tank before the'beer begins to flow. The filling tube and the parts connected therewith are all supported in therock plug in the casing 18 and they can be easily removed for cleansing or repair and replaced.
