SPECIFICATION forming part of Letters Patent No. 680,011 dated August 6, 1901. Applicantsfnedrbgngry a, 190i. serai No. 46.4.94. (No modem To all whom, t may concern."

Be it known that I, HENRY A. ALLWARDT, a citizen of the UnitedStates, residing at Detroit, county of l/Vayne, State of Michigan, have invented a certain new and useful Improvement in Soda-Water Apparat-us; and I declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference beinghad to the accompanying drawings,

which form a part 'of this specification.

. My invention relates to soda-Water apparatus; and the object, of my improvement-s is to provide an approved apparatus for refilling tanks with carbonated water which shall be simple in construction, Well adapted to be used with usual apparatus for this purpose, and which shall `utilize the residual gasesin the exhausted tanks. I accomplish this object in the device illustrated in the accompanying drawings, in Which- Figure 1 is an elevation of a carbonating apparatus embodying myinventiou,the chamber in Which the Water is mainly charged with gas being shown in section. Figs. 2 and 3 are sections taken at right angles to each other through the center of the tank. Fig. et is asection of the pressure-regulating valve. Fig. 5vis an enlarged sectional view of the automatic stop-valve, and Fig. 6 is a plan view in section of the valve and valve-seat shown in Fig. 5.

The same letter indicates the same part in each of the views.

A is a force-pump.

B is a carbonating-chamber.

C is a pipe which connects the chamber A with a source of supply of carbonic-acid gas under pressure.

D is a pipe by which the carbonatedwater may be allowed to flow from the chamber A. The gas is admitted through the pipe C and by suitable apparatus is kept at a certain pressure-say one hundred and eighty poundsin the chamber B. The Water is forced by the pump A into the top of the chamber B, where it is sprayed through a perforated plate to expose it to the gas, Which it absorbs, and it gathers at the bottom of the chamber, so as to cover the mouth of the outlet-pipe D.

I Fig. l.

E E are tanks in which the carbonated Water is supplied to retail dealers. These tanks are of the same construction and are only distinguishedin the reference-letters to indicate their relative positions, as shown in Through an aperture in the top of the tank E is fixed a plug F, which extends to near the bottom ofthe tank.

l plug F outside of said tank.

g is a passage extending through the nozzle.G and opening into a chamber Hin the plug F.

' the lower end of the plug F, extending to the fis a passage opening into the tank E at top of said plug and communicating at its upper end with the chamber II.

h is a valve adapted to close the entrance from the chamber H to the passage f.

I is a second passage in the plug F, extending from a point about quarter of the length of said plug from the top thereof, where it opens into the tank, to the upper end of said plug, at which point it passes througha nozzle J.

K is a chamber formed in the upper end of the plug F, forming an enlargement of the passage I.

7c is a ball in the chamber K. This ball is prevented from closing the lower passage to the chamber K by ribs 'L' z' il, Figs. 5 and 6, but is adapted to close the upper passage to said chamber when it is raised suliiciently.

The pipe D, through which the carbonated Water from the chamber B passes, is connected to the nozzle G. A pipe L is connected to the nozzle .I and leads to a reducing-valve M, which is adapted to open to permit the passage of a fluid from the pipe L Whenever the pressure in said pipe is greater than a certain amount less than the pressure in the chamber B say one hundred and sixty pounds. N is a pipe leading fromgthe outletpassage of the valve M to the inlet-nozzle G' of a second plug F of the same construction as the plug F.

n is a pressuregage on the pipe N. Other plugs, like F F', with their connected tanks, may be connected in the same Way, except that only one valve similar to M or gage similar to n will be required.

R is a pipe connecting the pipe C with the pipe L. r is a stop-cock on the pipe R.

S is a stop-cock on the pipe D.

s' is a stop-cock on the pipe N.

The operation of the above-described apparatus is as follows:y The tanks come in to be refilled with the plugs. F in them, the valves .h closed, the water withdrawn, but still filled with carbonio-acid gas at a small pressure. One tank is connected, as above described, to the pipe D, and one or more other tanks E are connected with the first, as above described. The cock r is opened, a1- lowing the gas to How into the tank E until the pressure therein is equal to that at which the valve M is set. The cock in the pipe D is then opened, allowing the carbonated Water to flow-into the tan-k E through the passage f. As the waterrises insaid tank it compresses the gas in the tank before it and absorbs a part of it. When the pressure of the vgas in the tank E exceeds one hundred and sixty pounds or the pressure to which the valve M is set, said valveopens, allowing the gas to pass byit and into the tank E. When the level of the water in the tank E rises above the lower opening of the passage I, the water rises in said passage, carrying the ball upward and closing the passage I by stopping the upper passage from the chamber K, whereupon the pressure in thetank rises to that of the chamber B and the water ceases to fiow. The valve h and cocks S are now closed, the tank E removed from the pipevD, the tank E put in its place, and a third tank put in the place of the tank E', and the operation is repeated.

lt may be noticed that in the above-described apparatus the tankis always tilled to the same extent-that is, to a level just above the lower end of the passage I-that all the residual gas of the tanks is utilized, that the water will always be carbonated to about the same extent, and that very little additional apparatus is required. Of course the cock s is closed before removing the tank E'.

What I claim is- 1. The combination With a tank E, having a passage-way opening toward its bottom, means lfor detachably connecting said tank with a source .of supply of carbonated water under pressure so that said water may enter said tank through said passage, said tank being also provided with a passage I opening into said tank near the top thereof, of a pipe L adapted to be detachably connected to said tank so as to form a continuation of the passage I, a pressurelregulatine,r valve on the pipe L adapted to open when the pressure in said pipe is a little less than the pressure forcing the water into the tank E, and a second tank E detachably connected to the outlet-passage of said red ucing-v'alve and adapted to replace the first-mentioned tank, substantially as described.

2. The combination with a tank E having a passage-Way opening toward vits bottom, means for detachably connecting said tank with a source of supply of carbonated water under pressure, so that said water may enter said tank through said passage, said tank being also provided with a passage I opening into said tank near the top thereof and provided with apparatusadapted to permit the passage of a gas, but to close the passage when the water fioWs therethrough, of a pipe L adapted to be detachably connected to said tank so as to form a continuation of the passage I, a pressure-regulating valve on the pipe L adapted to open when the pressure in said pipe isa little less than the pressure forcing the Water into the tank E, and a second tank E detachably connected to the outlet-passage of said red ucing-valve and adapted to replace the rst-mentioned tan'k, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.

. HENRY A. ALLWARDT.
