The housing` (1) for my carbonatorrests onabase (2)Y and'comprises an elevated bot.

toniplate (.3), arcylindricalvvvall (4) made.

preferably.of two concentric sheets (6)' of met-al' 'having heat insulating material such. as' asbestos between the-same asfshownat (7) i and Va ring (8) vchannel-shaped inA cross section lying on* top oit' the4 Wallv and engaging' theupper ends of the'tvvo concentricr sheets so as; tor` prevent displacement. ofrthe saine. Theieylindrical housing .is covered bymeanfs` of a suitable lid also preferably'illed with insulatingmateriial asv shownat (11) a knob (12) :facilitating the handling ofy the` same.vr f

In this: housing issupported concentric with the' same a cylinder` (13) engaging. a groove. (14:){inmthe'bottom'ol1 the.y housing and' a groove..(1(5f)A in a top plate (17 so as to form aV gasftight chamber (18). The upper: plate (17) is pressed'upon the vrWall (13) -aird'the latter upon theA bottom plate byfmeans of nuts; V(15) threadedly '-engag-ingrrodsi. (2O)V rising from the bottom on'v tthe ,outsidev oit'. the cylindrical Wall (13)A and extending through kpert'orations in the upper plate. k)Vater may be vadmitted Aintov thisjchamber through a'pipe' (19) connecting with any suitablefsource of Water, as for,

instance tlie city Water: ipes and provided` ber (18') serves/as a drainpipe.

Gasis admitted rome anysuitabl-'e lsupply through-the pipe by the iiollo'vvingfarrangement.;- .KA .sleeve (24)- threadedly en gages th'eibottom plate of'v the housing at itsr center 'and extends slightly above the bottomv member`` (3)1 and through a: considerable distance' below the latter member.4 ltsV lower end which is enlarged in crosstsection isf threaded internally as shown at (26) and is adapted to receive the upper reduced end of yav nipple I having a nozzle'(28) of very small cross sectionaliarea Whichrlatter threadefdly engages the end of the pipe ('23). 'lhesleeve (24') which is. showirwinfdetail' in Figures 5, G and 7 is adapted to serve as a guide member for the lower end of the stem (29) extending through the length of the chamber and is provided with a plurality of internal grooves (31) allowing the gas to pass the stem provided the latter is raised suliiciently high to clear the nozzle (28). The stem is provided in its lower end with a small body of rubber (32) which closes the nozzle (28) if the stem is pressed downwardly.

The upper end of the stem (29) is guided byl means of a sleeve (33) disposed in the center of the top plate and is provided near its top with a collar (34) adapted to be engaged and to be pressed down upon by the short arms (36) of a plurality of levers (37) pivotally supported between lips (38) extending downwardly from a ring (39) formed integrally with the sleeve The long arms (41) of the levers bear on the top surface of a float (42) so that when the float rises the stem (29) is forced downwardly and when the float falls the stem (29) is allowed to rise under the influence of the gas pressure.

The float (42) consists of a large plurality of inverted bells (43), one of which is shown in detail in Figure 8. Each bell consists of a disc (44) having a flange (46) depending from its outer circumference and having a depressed central portion (47) formed by an internal flange (48) and a bottom member (49). The latter has a central perforation (51) and the internal flange (48) is provided with a plurality of perforations (52) disposed in such a manner that they are below the disc (44) but above the lower eX- tremity of the outer flange (46). T he perforation (51) allows the bell to slidably engage a tube (53) which latter is made slidable on the stem (29). Between each two bells is interposed a spacing member (54) slidable on the tube and provided at its upper end with an enlarged cup (56) adapted to engage the depressed central portion of the bell above it whereby all the bells are held in parallel relation. The depressed central portion of the lowermost bell rests on a disc (57) provided with a flange (58) encircling said inner portion. This disc threadedly engages the tube (53) and all the bells and the spacing members are forced into one. firm unit by means of a nut (GO) threadedly engaging the upper end of the tube The disc is supported on the sleeve (24) which as previously stated extends sightly above the bottom plate of the carbonator. To allow gas to pass between the latter disc and the sleeve while the float is in its lowermost position l provide transverse grooves (58) in the latter sleeve as shown in Figures 5 and 6.

Carbonated water may leave the chamber through small passages (59) in the sleeve (33) so as to enter a tube (61) communicating with said passages through a port (62) in an embossment (63) to which the tube is secured by means of a union (64). The tube ((31) leads into the exterior by communicating with a pipe (G6) supported in a bracket (67) extending from the top plate (17 `Any suitable faucet may be connected to the latter pipe for withdrawing the carbonated water.

The operation of the device may be describet as follows: )Vater is admitted under pressure through the pipe (19) and the pipe is connected to a suitable source of carbon dioxide under pressure. Normally the pressure of the gas exceeds that of the water. lVhen there is neither water nor gas in the chamber (18) the float will descend to its lowermost position as shown in Figure 1. The gas being` under pressure will lift the rod suiliciently high to allow the gas to pass the same through the grooves (31) in the sleeve (24) at the same time the water rushes into the chamber. Both water and gas will first iill the lowermost bell, the gas rising and occupying the upper space while the water will occupy the lower space. A thin layer of gas will be entrapped in the valve while a surplus amount will follow the course of the water and rise with the same through the holes (52) to lill the space of the next bell. In a similar manner one bell will be filled after the other and a thin layer of gas will be trapped in each bell so as to engage a large area of water which will cause the gas to be readily absorbed by the water. The buoyant effect of the water on the gas entrapped under the bells causes the float to rise and lifts the long arms (41) of the levers (37) thereby depressing the collar (34) on the stem (29) and forcing the latter downwardly whereby the nozzle (28) is closed. Thereby the supply of gas is shut off and the valve for the gas supply is not opened until the gas entrapped under the bells is absorbed by the water. 1t will be seen that in this manner a thorough absorption of the gas by the water is obtained and that at the same time the gas supply regulates itself automatically in accordance. with predetermined rules.

I claim i 1. In means for charging a liquid with a gas, a chamber, means for admitting the liquid into the same, means for admitting the gas into the chamber and a float control for the gas including a plurality of inverted bells mounted above one another in spaced relation, each being adapted to trap a layer of gas, and having a downwardly extending central flange with an outlet therein disposed intermediately of the top of the bell and the lower extremity of the bell, said outlet being adapted to allow a surplus of gas to escape into the neXt higher bell.

2. In means for charging'a liquid -with a gas, a chamber, means for admitting the liquid into the. same, a central gas intake in the bottom, a vertical stem adapted to yclose the gas intake and a ioat slidable on the stem having means associated therewith for depressing the stem so as to close the gas intake when the float rises, the float com prising a plurality of bells arranged above one another in' spaced relation adapted to trap layers of gas within 'the liquid.

8. In means for charging a liquid with a gas, a chamber, means for admitting the liquid into the same, a central gas intake in the bottom, a vertical stem adapted to close the gas intake and a float slidable on the stemhaving means associated therewith for depressing the stem so as to close the gas intake when the float rises, the float comprising a plurality of bells arranged above one another in spaced relation adapted to trap layers of gas within the liquid, and having a downwardly extending central iiange with an outlet therein disposed intermediate of the top member and the lower extremity of lthe bell, said outlet being adapted to allow a surplus of gas to escape into the next higher bell.

t. In means for charging a liquid with a gas,ra chamber, means allowing the liquid and the gas to enter the chamber through the bottom thereof with the pressure of the gas rate the water and the gas in' successive layers in the chamber for securing a better absorption of the gas.
