To all whom it may concern:

llc it known that I, JOHN H. Fox, a citizen of the United States, residing at 228 East One Hundred and 'lwcuty-third street, New York, county of New York, and State of New York, have invented certain new and useful Improvements in Carbonating Apparatus, fully described and represented in thefollowing speci titration and the accompanying drawings, forming a par; of the same. or

The present invention relates to an apparatus employing a receptacle in which water and carbonic acid absorption of the gas.

The invention consists in various improvements upon the drawingtubc for drawing off the carbonated water, also in the perforated disks which are used for subdividing or diffusing the gas, and-in means for spacing them apart, and in the arrangement of the above mentioned parts in relation to one another and to the casing of the carbonator.

Heretofore, it has been common to draw the carbonated water from within the carbonator by apipc having a comparatively large inlet in which the free gas could find access and pass to the draft-arm or faucet deal of sputtering. 'lhe drawing-tube in the presentlinvention is extended into the Water in thev carbonator and'provided with small perforations which prevent the admission of large bodies of gas, or cause the gas if entering the drawing-tube to be finelydivided and mingled with the water, and thuswholly prevent? sputtering at the drait-arm. Where the tube is thus surrounded by water mingled with gas, and provided with numerous small perforations, the reduction of pressure within the tube which occuis immediately when the draft-arm is opened to draw off the liquid, causes a rapid flow of the water thropgh the perforations, which flow ontrains the particles of gas which are floating in the Water, and carries them with the water to the draftarm. The water drawn from sucha perforated drafttube is therefore very sparkling and contains a large proportion of the as.

Where disks-have been heretofore immersed in water within the carbonator, they have sometimes been flanged at the edges to support them; but when block tin in sheet form is used for the disks they require support at points intermediate to the edges; and such support l avoid in the present invention by means of spiders which may be formed with central hub, ra-.

diating arms, and a peripheral ring, so as to supportthe disks at the center, the margin, and at various intermediate points.

lleretofore, to prevent the displacement of the perforated disks within the carbonator durin trans ort-ation, a stop in contact with the casing has been applied .just below the water level.

rings 0 and the remaining and spokes or arms p to the edges or center of the disks; but in theprcsent invention I utilize the drawing-tube to hold the disks in place by extending the tube upwardly from the disks and clamping a collar upon the tube to hold the disks in place.

The invention will be understood by reference to the annexed drawing, in which Figure l is a sectional elevation of a carbonator containing both the disks of the drawing-tube; Fig. 2 is a sectional elevation of a carbonator containing the drawing-tub without the disks and having a gasspaco above the water-level; Fig. 3 is a sectional elevation of a carb'onator having 3 casing entirely filled with water; Fig. 4 is a plan of one of the perforated disks; Fig. 5 an edge view of the same without flanged edge;

and Fig. 6 is a transverse section of the same with one of the supporting spiders, and the disk formed with a marginal flange. Fig. 7 is a plan of one of the spiders; Fig. 8 is an edge view of the same, and Fig. 9 an edge view of a modification of the same.

The shell a of the carbonator is form with dome shaped top and its bottom closed by a base b. An angle-shaped ring 0 and bolts dare shown in Fig. 1 for securing the base to the shell.

A water inlet e is shown provided in Figs. 1 and 2 with a valve f regulated by a float-lever g, to maintain the water at the desired level. v A gas-inlet h is shown,

to which the ordinary gas-distributert' is attached and extended in the bottom of the carbonator with perforations upon its under side to diffuse the gas downwardly.

An outletj is shown in the base b for the carbonated water, and the drawing-tube is extended upwardly from the same in the center of the casing, reaching to the top of the shell in Fig. 1; and in Fig. 2 terminated Perforations l are shown at various --points in the drawing-tube.

Eight'disks m are shown in Fig. l of flat form provided with numerous small perforations n, as shown in Figs. 1 and 4, the two lower disks being separated by disks by the peripheries p and hubs p of the spiders shown in Figs. 7 and 9. Plain rings 0 are employed, as the presence of the distributor and of the gas-inlet fixture and water-outlet fixture would interfere with the arms or hub of the spider. The distributor is in practiceextended from the gas inlet h past one side of the drawing-tube, as shown in Figs. 1 to 3 inclusive.

The spiders are formed with peripheral ring hub p adapted to loosely encircle the drawing-tube k, attached to the hub and ring p. The arms and the peripheral ring are of uniform depth, but the hub is shownin Figs. 1 and 9 a little shallower than the arms, leaving a space at the edge of each hub shown of cylindrical p and at various points in the'lower part of the casing and. rises through the water, mingling with it and being abthe spiders.

through which the water may gain free access to the holes in the dmwi'ngtube, where they are situated between t disks. To afford such access, the hubs may be made of the same depth as the arms and ring, as shown in Figs. 6 and 8, and provided with perforations q to admit the water to the holes in the drawing-tube.

To stiffen the pans at the edge, they may be beaded or formed what a slight flange m as shown in Fig. 6, Within which the rings p of the spiders may be inserted. The flange or bead upon the disk is in any case made of less projection than the distance between the disks, so that the weight of the disks is supported wholly upon A collar r is shown clamped by a set-screw upon the drawing-tube contiguous to the upper disks m, and serves to hold all the disks from displacement.

The drawing-tube in Fig. 1 is shown provided with the perforations l" above the water level. Such -peif'oration is in practice made very small, much smaller than can be indicated upon the scaleof the drawing, and such hole operates to'permit a small supply of gas to enter the drawing-tube to mingle with the water drawn therefrom. It is found in practice that the gas admitted bysuch a. fine hole does not cause sputtering at the draft-arm or faucet, but docs make the water more gaseous.

In Fig. 2, the water level, as with the carbonator in Fig. 1, is kept at a suitable distance below the top of the shell to form a gas chamber, and no puns are shown in this construction, but the drawing-tube is connected with a water-outlet at one side of the center and is bent to bring it up into the center of the casing so that it will draw the water from all sides. The top of the drawingtube may be terminated in such a machine below the water level, as shown in Fig. 2, and made with or without a small perforation Z in the top.

In Fig. 3, the carbonator is shown entirely filled with water Hing supplied through the water-inlet e from a source of water under suitable pressure.

The gas admitted by the distributor i is discharged sorbed by it. Where the gas chamber is provided in the upperpart of the casing, the gas which is held in contact with the surface of the water is to some extent absorbed thereby. The sub-division of the gas by the perforated pans as the gas rises-upwardly through their numerous small holes, greatly promotes the discharge of the gas with the water through the small perforations of the drawing-tube k. Perforated pans have long been used to diffuse gas in water to promote its absorption, but never in connection with a drawing-tube having numerous perforations in the water-space, through which the gas could pass mingled 'with the water. The use of the perforated'drawing-tube extended into the body of water operates to draw off with the water small globules of gas which are rising and floating with the water, and such gas and water are thoroughly mingled, so that a large part of the gas thus drawn off is absorbed in the water in its movement through the drawing-tube and the conveying pipe. I find in practice that this drawing-tube prevents the continued'accumulation of the gas in the upper part of the casing, which often in the operation of other'carbonators renders it impossible to introduce a sufficient senses amount of water, and necessitates the blowing off of gas at intervals at the top of the shell, which necessarily involves great waste of gas. Theoxtension of the drawing-tubeupward in the center of the shell through the pan enables the drawing-tube to furnish a lock, in conjunction with the collar 2', to hold the pans in place, and perforations formed in the drawingtube between the pans also enables the drawing-tube to receive a certain proportion of the gas which is sub-divided in its movement through the pans and is passing upward between the same. The drawing-tube and the pans thus both cooperate to sub-divide the gas and ruinglcit in a finely sub-divided condition with the water, whether in the carbonator shell, the drawing-tube, or the pipe which conveys the carbonated water to the draft-arm It is obviously immaterial whether the arms p of the spiders are straight, as shown-in the drawing, or crooked.

The gas-inlet h and carbonated watcr-outlot j are both formed as thimbles extended through the bottom of the carbonator and clamped therein by nuts h and These thimbles are formed with threaded sockets upon their inner ends which face upwardly on the base I) of the cafbonator, and the gasdistributer i and drawing-tube I: are formed with threaded shanks adapted to screw into their respective threaded sockets. This construction enables the distributor and drawing-tube to be removed forrepairs, and it permits the shank of the distributor to be screwed into the socket oi the thimble h after the first perforated disk is set in place upon the lower ring 0, the shank of the distributor being bent atn'ght angles, and the first pan being formed with a hole to permit the passage of the shank through the same, by which it can be screwed into the socket of the thimble h before the other pans or the shell (1 are set upon the base. Special spiders may be made to support the two lower pans instead of the plain rings 0 to rest upon the base I by cutting out a portion of the arms of the spiders where the'distributer would inter sect the some. The relation of the distributor to the spiders is indicated by the dotted lines tin Fig. which show the distributer extending from the gasinlet h at one side of the center.

It is preferable to locate the drawing-tube in the center of the shell a, as shown in Figs. 1 and 2, so as to draw the gas and water equally from all sides; and in building new machines the thimble j for the draw ing-tubo may therefore be placed in the center of the base. In applying myimpioie'd drawing-tube to ma chines in which the gas-inlet and water-outlet .art placed near opposite edges of the base,'.the drawingtube may have a bent shank, {as shown in Fig. 2, to bring the perforated portion of the tube inthe center.

In Fig. 2, the jetsof gas from the holes in the distributor are shown passing downward behind the hori zontal portion of the drawing-tribe which is entirely unporforated. -If' the drawing-tube" were perforatcc'! at this point the gas would flow directly into the perforations and would cause a great deal of sputtering when the liquid was drawn froin'the di af tfa rm.

By perforating the drawing-tube at various pointe in its height above the level of the'disti'ibutcr, thr water .is drawn from difiorentlevels within the shell and water in different degrees s'f carbonation is thin mingled together.
