IMPROVEMENT IN APPARATUS FOR DISPENSING SODA-WATER, &c.

Specification forming part of Letters Patent No. 179,584, dated July 4, 1876 application filed May 15,1876.

To all whom it may concern:

Be it known that I, JOHN MATTHEWS, of the city, county, and State of New York, have invented certain new and useful Improvements in Apparatus for Dispensing Soda-Water, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to apparatus such as is employed by druggists and others who dispense soda-water and sirups at retail, and embraces instrumentalities by which, first, a great economy of space is secured on the dispensing-couuter; second, instrumentalities by which the soda-water and other beverages are conveniently dispensed; third, to instrumentalities by which the sodawater tumbler is rapidly and conveniently pressed and held to the draft-cock, (particularly useful in cases where the aerated beverages are drawn into the tumbler under pressure;) fourth, to instrumentalities by which the refrigerating ef fect of the ice is applied so as to cool the sir-ups and beverages in large quantities, and more efficiently than in the devices now in use; fifth, to instrumentalities by which the icewa-ter from the ice-chamber of the apparatus is made available for washing and cooling the tumblers; sixth, to instrumentalities by which economy of ice is effected; seventh, to instrumentalities by which the effective temperature of the liquid serving as a cooling medium in the ice-chamber is indicated on the exterior of the apparatus; eighth, to instrumentalities by which the pressure of the beverages is registered on the exterior of the apparatus; ninth, to instrumentalities by which.the fluids entering and discharged from the apparatus are neatly and conveniently conveyed; tenth, to instrumentalities by which the tumblerwasher is combined with the apparatus; eleventh, to in'strumentalities by which the sirup can be expeditiously supplied and dispensed from the apparatus; twelfth, to instrumentalities by which economyof space in the disposition of the sirup-tanks and other parts of ratus is large, it cuts off the view of the interior of the store from the. street, and obstructs the view of customers entering the store.

Second. The draft-arms and faucets on the ordinary apparatus generally project from the sides of the apparatus, and greatly increase the space necessary to operate the apparatus.

The soda-water tubes generally pass between the sirup-tanks, and require an increased size of apparatus to admit these pipes.

Third. The ordinary apparatus is not provided with any efficient means of drainage ftp the d rippings from the faucets, an d the overflow of tumblers when operating the apparatus. The dripping extends over a large part of the counter, as the faucets project for a considerable distance from the apparatus.

Fourth. The ordinary apparatus is'not provided with a tumbler-washer, which is usually placed at some distance from the apparatus on the counter. If the apparatus has faucets on different sides the tumbler-washer is not readily accessible to the operator, unless operating on one side.

Fifth. The draft-faucets in ordinary apparatus being necessarily arranged on different sides, in apparatus having a large number of such faucets soda-water, 850., cannot be as conveniently dispensed as would be possible if all the faucets were accessible to the operator without change of position.

Sixth. In dispensing soda-water according to my system, protected by Letters Patent issued to me January 25, 1872, and numbered 128,410, it is very convenient to have the drinking-tumbler carried and held to the draft-nozzle by means of a treadle operated by the foot. Such a means of operating would be attended pipe and an accumulation of water in the icechamber. v

Eighth. In ordinary apparatus provided with coolers, either of the cylinder form or with coil and cylinder, the arrangement is not such as to contribute to the cooling of the beverage in the most eflicient manner. The accumulation of gas in the cylinder-coolers, owing to the current being from end to end, only prevents the water from acting well on the ice, and if submerged in water, the water is rapidly warmed by the conduction of the metallic lining of the ice-chamber. In pipe coiled as a helix and lying upon the bottom of the icechamber no provision is made for the deposits of sand and other debris which flow from the melting ice, and is deposited upon the coil.

Where the cylinders are of copper, superficially washed with tin, the copper contaminates the water as soon as the tin-wash is worn off. If jacketed with copper, the expense of manufacture is increasedand its conducting power diminished; and if not jacketed, the tin, being a very soft metal, is liable to swell and burst under the pressure to whichit is subjected.

Ninth. In ordinary apparatus the coolers, ice, and lee-water are in contact with the m eta-llic lining of the ice-chamber, which, by its con ducting power, contributes to the melting of the ice without useful effect, and prevents, to some extent, the cooling of the beverages.

Tenth. Apparatus of this description, as at present manufactured, are not provided with any devices by which the temperature ot'the icechamber can be readily ascertained, and frequently the ice-chamber is without ice, as its conditions can only be known by opening the ice-chamber.

Eleventh. Such apparatus as at present manufactured is not provided with any such means by which the pressure on the water is inticated. 1t frequently happens that, owing to leakage or to the neglect of the operator, who aerates the waters, or the manufacturer who furnishes it, the pressure on the soda-water is insufficient to produce beverages of the required excellence as to aeration, pungency, 850. Such short-comings can be known only by troublesome inspection and careful tests.

Twelfth. In apparatus as at present man ufactured the sirups are dispensed from the siruptanks at an orifice which is necessarily above the tumbler. The space below the tanks in such apparatus cannot be used as a reservoir for sirup, and is generally not utilized,1naking the case larger than is required if otherwise arranged so that the space can be utilized.

Thirteenth. I11 ordinary apparatus the siruptanks are arranged at the side of the ice-chamber. The cooling of the sirups is thus imperfectly accomplished, as, by the melting of the ice, the upper parts of the tanks are no longer in contact with the ice, and to keep the icechamber always full is difficult and impracticable in such apparatus.

Fourteenth. In the ordinary apparatus, as generally constructed, having covers and doors constructed of plates of marble, much breakage ensues, owing to the falling or slamming of these marble doors.

Fifteenth. In ordinary apparatus having faucets connected with the sirup-tanks, such faucets generally pass the marble walls of the apparatus. The attach ment thus prevents the withdrawal of the tanks unless the faucets are first disconnected.

In the accompanying drawings, Figures 1 and 2 are side elevations of my apparatus, partly in section, and Figs. 3and 4 cross vertical sections of Figs. 1 and 2, respectively, the same letters indicating like parts in all the figures.

First. I effect a great economy of space on the dispensing-counter by constructing the main body of the apparatus A so that it is sustained above its base by columns B. This renders the space upon the base beneath the apparatus available for a tumbler-washer, J, and tumblers, and brings the draft-faucets E beneath the body of the apparatus, thus enbling the base of the apparatus to form a drainer, by which all the drippings from the faucets may be kept within the space occupied by the apparatus. The view of the customers and ot' the. store is less obstructed by this arrangement.

Second. The beverages are more conveniently dispensed by thus arranging the body of the apparatus above the counter, as all the dispcnsingfaucets are thus brought withina convenient space, and the tumbler washer and drainer are brought near to the dispensingfaucets, which have their outlets more equally accessible than in apparatus where the fancets are arranged on several sides of the apparatus. The beverage, when drawn, can be passed to the purchaser when in positions inaccessiblein apparatus of ordinary construction.

Third. The draft-faucets being beneath the. body of the apparatus enables the operator to use a tumbler-carrier, H, operated byatreadle, I, to hold the tumbler to the dispensingnozzle, as shown at p. This is particularly use ful where the soda-water is drawn in tumbler under pressure, as in my improvement pro-- ratus a sufiicient descent for the ice-water is obtained to enable it to be ofuse as a supply for the tumblerwasher, and also as a means of keeping the washing-water cool. The icewater is conveyed by a tube, W, passing through the column upon which the body of the apparatus is sustained, and is connected with the tumbler washer below the base. Great economy of water and advantage as to cooling the tumblers are thus obtained by unit ing the tumbler and drainer J with the ice chamber M. 7

Fifth. I construct the coolers of my apparatus as follows N is the storage-cylinder, issuing from one end of which is a tube coiled around the outside of the storage-cylinder. The beverage to be cooled enters the storagecylinder at such an angle as to cause the stream to impinge against the inside of the cylinder-wall, sweeping around the cylinder as a flat helical current, and leaving the cylinder at the other end by the coiled tube, and passing around the cylinder through the tube, and from thence to another cooler, N, constructed in a similar manner, forming a series onto the dispensing-valve. The pipe coiled on -the exterior of the storage cylinder is coiled tightly against the cylinder, and secured to it by soldering, or-other support, but sufiicient space is left between each coil to allow the ice to penetrate between'the coils to the cylinder, and so that the impurities contained in the ice are readily washed away by the ice-water, and not lodged between the coils, nor upon the cylinder, as these deposits greatly impair the refrigerating effect of the ice upon the beverages.- The pipes thus coiled also assist in sustaining the pressure upon the walls of the stora-ge-cylinder, and prevent the swelling of the cylinder by pressure. These coolers lie horizontally within the ice chamber, and are immersed in the water from the melting ice to an extentequal to about one-half their diameter. The level of the water is maintained by an overflow-pipe. This water is cooled by the waterrotatin g in the cylinder and coiled pipe, and acts asa reservoir of cold in a most effectual cooling medium. In coolers ot' ordinary construction such a reservoir cannot be effectively used, because those portions of water reduced to a low temperatureby the ice are not swept through the reservoir of water by currents which alternately reach thoseportions of the coolers in direct contact with the ice and the reservoir of water. A cooler constructed according to my improvement is efficient as a cooler on all sides, because the water in which the cooler is partly or wholly immersed is kept cold by currents in the cylinder and coil, which act alternately upon the ice and the ice-water reservoir. The presence of water in the ice-chamber is generally objectionable, as by reason of its extensive contact with the metallic lining of the ice-chamber much heat is conveyed to it, and, though ice is thus rapidly melted, but little useful ctfect is obtained, and generally the beverages cannot be drawn as cold as when the ice-water is absent. a

Sixth. I avoid these difficulties by a lining of non-absorbent and non-conducting material, M, placed within the external case and water tight lining, such non absorbent and non-conducting material being directly in contact with the coolers and ice, and forming the walls of the ice-chamber. For this purpose I use, preferably, a light wood, or other porous or fibrous material, well dried and saturated with par-aftine, or other equivalent material,

.or any material-such as gutta-percha, indiarubber-which is non absorbent, and a poor conductor of heat. In my improvement the metal jacketl acts as the water-tight receptacle, the non-absorbent lining being simply placed within it. or the non-absorbent lining may itself be made water-tight, and thus dispense with the metallic jacket. As the wood, if saturated with parattine or other oily or equivalent substance, where used against the marble, might stain it, I cover the prepared wood with a metallic foil or sheet where it is in contact with the marble.

Seventh. For reasons already stated, and indeed obvious, it is desirable to know the effective temperature of the ice-chamber without the difliculty of opening the apparatus. 1 therefore construct myapparatus with a thermometer, .Y, having its bulb immersed in the ice-water reservoir, and protected by a casing to prevent fracture, and its graduated scale so exposed as to read 011 the exterior of the apparatus.

Eighth. It is very desirable to have some means by which the pressure otthe beverages, upon which their good quality largely depends, is registered upon the apparatus. By this means the escape'of gas is readily detected, and

oversights and disputes avoided. I therefore construct my apparatus with a pressure-gage, O P, connected with the coolers or conducting-pipes in the apparatus, and having its dial arranged so that it may be read on the exterior of the apparatus.

Ninth.'The columns or walls sustaining my apparatus serve as a means by which the fluids entering the apparatus, and the drainage water from the ice-chamber, and condensed water which may lodge upon the plate of the apparatus, are conveyed in a neat and convenient style to and from the apparatus.

Tenth. To bringthe tumbler-washerJwithin aconvenient space, and to make it a useful part of my apparatus, I construct the base A of my apparatus with the upper surface, having inclination toward that part of the' base where the tumbler washer is placed, so that all drip from the faucets is conveyed to the tumbler-washer. The tumbler-washer is supplied with water in the usual manner, and, besides, is connected by the pipe or pipes W, which conveys the water from the ice-chamber and other parts of the apparatus. This serves to keep the Water in the tumbler-washer, and

furnishes a considerable quantity of water for washing purposes. The tumblers are thus kept cooler and cleaner than without such ad ditional source of water. And the connections with the drain-pipes is simplified, as the same pipe as is used for the tumbler-Washer serves to discharge all the drainage-water from the apparatus.

I Eleventh. In my improved apparatus I'arrange the sirup-cans as follows: F F F F are the horizontal sir-uptanks, which lie below the ice-chamber and rest upon the plate'of the apparatus. These tanks are provided with faucets at one end, from which the sirups are dispensed, and at the top at either end are perforated with an orifice. To fill with sirups, the tanks are drawn out till the supplyorifice is accessible. To dispense the sirups, the tanks may be drawn out a shortdistance to bring the dischargevent over the tumbler. The plate a may be perforated to permit the discharge ot'sirups through the plate, in which case the dischargevalve is operated within the tank by means of a lever or connectingrod, accessible from the outside, or the sirupfaucets may project from the tanks sufficiently to permit the tumblers to be supplied with sirup from the sirup discharge vents. This arrangement of sirup-tanks permits the use of aportable tank, and which can readily be removed for cleansing, 86C.

Gr G G G represent npright'portable tanks, with two methods of operating the same in the long series. The sirups are dispensed through orifices in the plate, the valve being operated by stems X passing through projections in the apparatus provided with covers. The other upright portabletanks are shorter, and dispense the sirup in a tumbler-chamber, g, which is accessible by means of a door, Q, the turnblers being brought in each case to the required position by means of a tumbler-guide, as shown in my patent dated October 3d, 1865, and numbered 50,225. The upright portable tanks of both series operate as described'in that patent.

Twelfth. This disposition of the sirup-tanks permits of their disposition so as to occupy all space in the apparatus not needed for other portions, and makes available the space usually lost in apparatus resting on the counter in the usual manner.

Thirteenth. I avoid the breakage ofthecovers and doors of the apparatus, which, in ordinary apparatus, is of frequentoccurrence, by providing the apparatus with a dash-pot, which receives the covers, and permits them to close gradually, thus avoiding all shock to the mardia-rubber or other elastic material, to receive the cover or door. The upper part of the cylinder is perforated by a small orifice, which is also carried through the rubber butter. f is the air-space within the cylinder when it is raised upon the piston by the spring d.

The operation of the dash-pot is as follows: The door being open the cylinder is raised bythe spring d, the air passing through the oritice'i at the topof the cylinder, the door of the apparatus being closed, it first strikes the rubber buffer g, and closes the air-orifice i. The weight or pressure of the door forces down the cylinder and compresses the air within the space], and the cover or door slowly settles to its place without shock, as the air gradually escapes between the piston and the cylinder. In some cases I prefer to bore a small hole in the cylinder, to permit the air to escape more freely. The pin and socket at the lower end permit a small movement of the dash-pot, which, owing to the are described by the door working on hinges, requires this equivalent mode of compensation or adjustment ot'the dash-pot. When the door is raised, the cylinder of the dash-pot is raised by the spring. The air entering through the orifice t' permits the dash-pot to rise quickly, in order that it may be at once ready to receive the cover or door, it"itshould soon he closed. The dash-pot would rise very slowly if not vented,

and in some cases would not in time receive ers, tul'ubler-washers, dash-pots, and other indiv idual parts of the apparatus.
