SODA-WATER APPARATUS.

SPECIFICATION forming part of Letters Patent N0. 394,834, dated December 18, 1888.

Application filed March 17, 1888. Serial No. 267,481. (No model.)

To aZZ whom it may concern:

Be it known that we, HENRY F. CLEEVE, a subject of the Queen of Great Britain, residing at Lyndhurst, in the county of Bergen and btate of New Jersey, and JOHN PARKER, a subject of the Queen of Great Britain, residing in the city and county of New York, in the State of New York, have invented a certain new and useful Improvement in Soda-Water Ap- IO paratus, of which the following is a specification.

\Ye use the term soda-water in its popular sense to designate water which has been caused to absorb carbonic-acid gas, in which it is retained under pressure.

The invention relates to the apparatus for manufacturing of the class known as continuous, in which class the carbonic acid is manufactured at ordinary pressures and is compressed by apump.

Our improvements overcome the difiiculties heretofore experienced from the heating of the pump when the wateris shut off, avoiding the necessity of the ordinary water-Jacket around the pump, and works successfully and economically under all conditions without requiring attention. \Vhenever the pressure in the pump is in excess, gas or water, or both, are delivered back into the feed box, and whenever more gas is received in the feedbox than can be absorbed by the water at the moderate pressure which obtains there the excess will be delivered into the gasomcter. The water also which escapes from the fountain through the safety-valve when the water rises too high is also delivered into the feedbox, and as its excess of carbonic-acid gas escapes it is largely retained by the. feed-water. The partial charging of the water with carbonic acid. by this means previous to its introduction into the pump contributes to the rapidity and the economy of the process of charging.

The accompanying drawings form a part of this specification and represent what we consider the best means of carrying out the invention.

Figure 1 is a vertical section, partly in elevation, slmwing the entire apparatus, and 50 Fig. 2 is a vertical section showing a portion on a larger scale.

Similar letters of reference indicate cor responding parts in both the figures where they occur.

A is the ordinary frame-work, and B the pump, operated as usual, and delivering into the fountain C. It receives gas from the ordinary gasoineter, D, through a. pipe, d, and receives water from the feed-box E through a pipe, e. The capacities of these pipes (Z and 6 may be controlled by stop-cocks, one stop-cock for each pipe, arranged and operated in the ordinary manner. \Vater is supplied to the feed-box through a pipe, f, controlled by a stop-cock, f, operated by a float.

So far as yet described the apparatus is constructed and operated in the long-approved manner. The provisions for introducing a constant or intermittent supply of carbonic-acid gas at ordinary pressures into the gasometer D and for taking the water from the fountain C and bottling or otherwise utilizing it may be of any ordinary or suitable character and need not be represented.

A safety-valve, G, is mounted on the fountain (l, and when through a temporary cessation of the bottling or other cause, the continued working of the pump l5 accumulates too much pressure in the fountain the safetyvalve opens and relieves the pressure; but instead of, as usual, connecting to the top of the fountain, this safety-valve. is provided with a pipe, 9*, reaching down in theinterior of the fountain. Its lower open end is at the level to which itis desired to limit the rise of the water. So long as the water-level is below this point gas alone will be delivered through the safety-valve; but when the water-level rises above this point water alone will be delivered. Under ordinary conditions the pressure, when in excess, will. find the water-level so close to the lower end of this tube that the saturated water and gas will be delivered together in varying proportions through the safety-valve. A flexible diaphragin, H, connects the stem of the safetyvalve with an iuclosiug-casing, G, as fully shown in Fig. 2. The upper portion of the casing allows the stem to move loosely and freely up anddown with no attempt at tight- IOO ness. It is simplyguided. Butthe diaphragm lI below forms an impermeable barrier for the gas, which is thus restrained and compelled to flow away through the pipe 9, which extends into and along the bottom of the interior of the feed-box E, where it is provided with fine perforations g.

The mingled gas and water, or either alone, rising through the safety-valve (ir, is disposed of as follmvs: The water thus rising tlows through the pipe q and the apertures g to mingle with the fresh water in the feed-box. The gas thus rising through the safety-valve G, as also the as given o'tl from the saturated water on its release from pressure, is restrained by the diaphragm ll and caused to flow through the same pipe g. It is distributed in the feed-box E through the apertures g. ()n rising in fine bubbles it is abstn-bed by the water until the latter is partially saturated. Any excess of gas not thus absorbed will pass through a second safety-valve, K, which may be lightlyhmded, and is delivered through 7r into the gasometer I).

There are frequently-reeurring intervals in the continuous process of charging water with 5 gas in which an excess of pressure exists in the fountain and is relieved by the safetyvalve G. Our apparatus insures that water shall be delivered instead of gas if the water tends to rise too high, and insures that 0 whether water or gas it shall all be retained and delivered into the feed-box without materially affecting the delicacy of the safetyvalve. It contributes to the economy of the process and to the efficiency of the apparatus of given capacity by causing the water to be delivered from the feed-box already partially saturated with the gas. An excess is promptly delivered into the gz'isometer and occasions no ditficulty. 40 It is important to keep a liberal quantity of the gas under pressure in the fountain as a means of maintaining the pressure and the saturated condition of the water when the water-level in the fountain is lowered by rapid bottling. The impin-tance of thishas been so fully recognized that expensive apparatus has been heretofore employed,operating by the weight of the fountain to eheck the water-sup ply and increase the proportion of gas whenever the water-level tended to rise too high.

0111' causing the safety-valve G to communicatewith the interior of the fountain at a low point attains prz'ietically the same end.

When the water is shut off and the pump B treats gas alone, it becomes heated to such an extent as to ruin leather packings. A jacketaround the pump, through whieh a constant stream of cold water'is caused to flow, reduces the risk from this source. Our appa- 6o ratus avoids the necessity for such eumbrous and imperfect devices. ()ur pump may be allowed to pump a constant supply of water,

ing from the principle or saeritieing the ad- 1 vantages of the invention. \Yhen the fresh water is received through the pipe f at a suflieient pressure, the second safety-valve, K, may be loaded so as to maintain a considerable pressure in the feed-box, which will allow a still greater degree of saturation of the water therein. It will be undcn'stood that in such case the load on the safety-valve (t should be proportionately lessened, so it will rise against the pressure above itand properly relieve the fountain, avoiding the possibility of an excess therein.

\Ve have described the invention with particular refcrenee to the manufacture of soda water; but it will be understood that the apparatus maybe used successfully in charging other liquids, as cider, wine, the.

\\'e claim. as our invention- 1. in an apparatus for soda-water manufacture, the fountain C, gas-pipe (7, connecting with the gasometer l), feed-box E, water-pipe e, and provisions, as the pump B, for introducing water and gas into the fountain, in combination with each other and with the safeti y-vz'ilve G and pipe g, leading gas and water from the fountain back to the feed-box, all substantially as herein specified.

In an apparatus for soda-water man u facture, the safety-valve (Jr and coimection g, leading therefrom to the feed-box E, in combination with the fountain (l, feed-box E, and gasolncter l), and with the connection 7r,leading from the feed-box to the gasometer, so that the gas and water escaping from the fountain is delivered into the feed-box and the gas not absorbed by the water in the feedbox is discharged into the gastnneter, ashorein specified.

3. in a soda-water apparatus, the safetyvalve G on the foimtain 0, having a connection, g ,communicating with the interior of the fountain at the desired water-level in the latter, so as in delivering to relieve the gases of 1.)r(.*ssure it will deliverwatcn' whenever the water rises above that level and gas when it is below that level, substantially as and for the purposes herein specified.

In testimony whereof we have hereunto set our hands, at, NewYorlc city, this 16th day of March, 1888, in the presence of two subscribing witnesses.
