1 '0 all whom it may concern:

Be it known that I, Tnoms J. KIERNAN,

a citizen of the United States, residing at Arlington, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Carbonators, of which the following is a specification.

The invention relates to carbon'ators. The object of the invention is to improve upon the construction and arrangement of the parts of a carbonating apparatus in order that theprocess of charging water or other liquids with carbon dioxide or other gases may be performed more efliciently than is possible with carbonators as at present con structed. With this object in view, the in' vention consists in the improved carbonator hereinafter described and articularly pointedout in the appended c aims.

The preferred form of the invention is illustrated in theaccompanying drawing in which the figure is a vertical sectional view of the improved carbonator. As illustrated in the drawin the carbonator comprises an upright cylin rical tank 1 closed at the top a cover 2 and at the bottom by a base b plate 3 from which depend legs 4 which supvalve 16 is opena check valve 17 is provided,

port the carbonator in position. The water or other liquid is supplied to the tank throu h a liquid inlet 6 and pipes-7 and 8. A va ve 10 arranged to close against the valve seat 11 located in the inlet casing 12 is adapted to shut ofl the supply of liquid when the liquid in the tank 1 reaches substantially the point 13. While the valve 10 is open, ermitting liquid to flow into the tank. lea age around .the valve stem 14 is prevented at the stufling box 15 b means of a second valve 16 mounted on the valve stem 14 and arranged to function opposite to the valve 10. That is to say, when the valve 10 is open, the valve 16 is closed preventing the escape of liquid through the stuffing box 15; and when the valve 10 is closed, the valve 16 is open. To prevent the escape of gas through the stufling box 15 when the located in the elbow 18 at the joint between the pipes '7 and 8.

When the liquid has risen in the-tank to substantially the point 13, a float 20 operates to close the'valve 10. The float 20 is supported on the end of a lever arm 21 ficiently charged with carbon dioxide or which passes through a slot 22 formed in the side of the tank and is pivotally mounted at an inlet casing 23 on a bracket 24 secured to the exterior of the tank. Internally and externally arranged plates 25 seal the joint where the lever arm 21 pierces the tank. The stem 14 of the valve 10 is articulated by means of a pin and slot connection with an arm 26 secured to the pivot upon which the float 20 fulcrums. When the rise of liquid to the point 13 lifts the float, the latter causes the arm 26 to swing in a counter-clockwise direction and pull the valve stem 14- to the. ri ht to seat the valve 10, thereby shutting -o the supply of liquid.

The carbon dioxide or other. gas is supplied to the tank through a gas inlet 28 and pipes 29 and 30. The pi e 30 discharges into a manifold 31 located in the bottom of the tank. Two dischar nozzles 32 connected with the manifol 31 direct the gas against two curved blades 33 secured to a vert1cally-arranged shaft 34 journaled in the top of the manifold 31. On the upper -end of the shaft 34 are fixed wire mesh blades 35. The general arran ment and construction of these parts may as usual.

The construction is suth that the impingement of the gas against the curved blades 33 causes the shaft 34 and the blades 35 to rotate, thereby stirring oritating the liquid and causingthe gas an the liquid to be thoroughly mixed.

. he supply of carbon dioxide or other gas to the tank is controlled by a valve 37 arranged to close against a seat 38 located in 39. The valve 37 is fixed on the outer end of a valve stem 40 articulated by a pin and slot connection with an arm 41 secured to the pivot pin 23. The arms 41 and 26 and the pivot pin 23 constitute a rocker arm construction. When the float 20 rises to shut off the supply of liquid to the the va V0 10, the arm 41 is swung to move the valve stem 40 to the left to unseat the valve 37 to permit the gas to enter the tank. While the valve 37 is unseated a valve 42, also supported on the valve stem 40, is closed its'seat to prevent gas from escaping throughthe stufiing box 43. The escape of gas h the tank by closing throng valve 42 and stufling box 43 when the valve 37 is seated is prevented by means of a check.

valve 45 located in an elbow 46 at the joint between the pipes 29 and 30. r

When the liquid 'n the tank has been sufother gas, the charged liquid is'drawn ofi no liquid can enter the tank because of the I pressure therein. The charged liquid is withdrawn from the tank until a semicircular float 50 settles down on the ofl'set end 51 of a vertically arranged rod 52 and thereby unseats a valve 53 which controls a vent 55. The .float 50 is provided with ears 54 which loosely engage the rod 52, so that the rod 52 acts as a guide for the float 50. The rod 52 also serves as a valve stem for the valve 53. When the weight of the float 50 unseats the valve 53 the tank is reduced to atmospheric pressure through the vent 55 so as to rm1t the pressure of the liquid to unseat t e check valve 17. The floats 20 and 50 are provided with the pressure equalizers 56 and 57 respectively.

The operation of the improved carbonator is as follows: The liquid control valve 10 bein unseated the water.or other liquid flows throu h the pipe 7, unseats the check valve 17 and passes intothe tank through the pipe 8. When the liquid has risen in the tank to the predetermined level 13, the float 20 is lifted and through the connections between closed, whereas the latter cause a thorough mixin ofl throu h t 0 outlet 48.

it and the valves 10 and 37 the former is is opened to perother gas to enter as enters the tank through mit the carbon dioxide or the tank. The the pipe 29 and of the gas being suflicient to unseat the check valve 45. As the gas enters the tank through the discharge nozzles 32, it impinges upon the curved-blades 33, thereby rotating the shaft 34 ,u n which the mesh blades 35 are fixed. 'llie rotation of the blades 35 agitates the liquid sufliciently to of the liquid and the gas. When the liquid has become sufficientlychar with the s, it is drawn The fall in the level of t e water "causes the float 20 to drop and thereby close the gas control valve 37 and open the liquid control valve 10. The pressure of the gas in the tank, however, prevents the liquid from unseating the check valve 17, so that no liquid enters the tank until the latter is thereby unseat the valve 53, the interior of substantially empty. When the charged liquid-has been drawn ofl? sufliciently to permit the float to settle -unto the ofl'set end 51 of the rod 52 and the tank is reduced to atmospheric pressure. This permits the flow of liquid to unseat the check valve 17 and flow into the tank. When the liquid has risen to its predetermined level 13, the float'50 is lifted against a pin 59 secured'to the rod 52. The engagement of the float 50 with the pin 59 lifts the pipe 30, the pressure the rod 52 and thereby closes the valve 53. During. the closing of the valve 53, the float 20 has operated to close the valve 10 and open the gas valve 37 to permit a fresh supply of gas to enter the tank.
