APPARATUS'FOR CHARGING PORTABLE FOUNTAINS WITH CARBONATED BEVERAGES.

SPECIFICATION forming part of Letters Patent NO. 484,078, dated October 11, 1892. Bpplication filed February 10, 1891. Serial No. 381.007. (Nu model.)

To a53- whom it may concern:

13c known that 1, Jason F. i ITTEMANN, a citizen of the United vStates, and a resident of Yonkers, Vestchestcr county, State of New York, have invented certain new and useful lmg irovcincnts in Apparatus for Charging Portable Fountains with Carbonated BGVLT- ages, of which the following isa specification.

This invention relates to an improved apparatus for charging portable fountains having but one valve with carbonated beverages, said apparatus being so constructed that the fountain is first charged with carbonic-acid gas of a certain pressure and then with the arbonated beverage at a higher pressure, so thatthe gas in the fountain is compressed by the liquid and the supply of the liquid automatically discontinued when the fountain is charged with the required quantity of carbonated liquid.

The invention consists of an apparatus for charging portable fountains with carbonated beverages in which the fountain supported on a balanced platform and its valved inletpipe connected by a flexible pipe with a switclrpipe and three valves, said valves being respectively connected with a carbonic- T apply pipe for charging the fountain gas under pre sure, for charging the \in with carbonated liquid under higher .re, and for permitting the drawing off of the surplus gas from the fountain, so as to conduct the same to a suitable storage-tank.

The invention consists, further, in certain details of construction and combination of parts, as will be fully described hereinafter, and iinally pointed out in the claims.

In the accompanying drawings, Figure 1 rep resents a sectional side elevation of my imcrov ed apparatus for charging portable fountains with carbonated beverages. Fig. 2 is a side elevation, drawn on a larger scale, of the supportingstandard for the fountain-platform and the different stop-cocks by which the fountain is connected, respectively, with the reservoir containing the carbonated beverage, with the gas-supply, andwith the tank to which the surplus gas is conducted off from the for. Fig. 2 is a detail vertical transthe valve for discharging or shifting off the surplus gas in the founiiig. 3 is a front elevation of Fig. 2,

partly in vertical transverse section. at is a plan of Fig. Fig. 5 is a detail vertical transverse section of one of the valves en1- ployed for charging carbonic-acid gas or car bonated liquid to the fountain; and Figs. 6 and 7 represent; respectively, a detail vertical central section and a horizontal section on the line 7 7, Fig. 6, of the spray-head through which the carbonated liquid is discharged in a spray into the reservoir from which the liquid is to be charged into the fountains.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a closed reservoir, which. is supplied with. car bonated liquid by a supply-pipe a, and which is provided at the interior of the reservoir A with a spray-head l The spray-head l; is formed of two semicylindrical sections 1) Z), which are provided with a number of radial spray-channels b of conical shape, that taper from their larger inner ends to their smaller outer ends, as shown clearly in Figs. (5 and 7. The sections of the perforated spray-head B are connected by screw-caps b at their upper and lower ends, said caps engaging the extcriorly-threaded tubular ends 11 f thcsprayhead. From the top part of: the spray-head extends in downward direction a conical deflector Z), that rests by its enlarged head 11 011 the upper end b of the spray-head, a id is firmly held in position by the top cap 1) of the same, as shown in'Fig. G. The construction of the spray-head B of two sections facilitates the convenient cleaning of the same, as the parts can be readily taken apart by removing the screw-caps. A constant supply of carbonated liquid under pressure is forced into the reservoir A either by a pump or by an ejector, so that theliquirl is delivered ina thoronghlyanixed state into the reservoir A. The gas and liquid may, however, be separately supplied to the reservoir and mixed in the same by the action of the spray-head B. A check-valve is preferably arranged in the supply-pipe a, so as to retain the necessary pressure in the reservoir in case the fe .J. connection should get out of order.

The reservoir A is provided with a suitable gage a for indicating the level of the liquid in the same. The spray-head B is arranged above the level of the liquid in the upper pipe D, that is part of the reservoir, so as to produce the atomizing of the liquid in a fine spray into the carbonic-acid gas contained in the space above the liquid. The conical deflector in the spray-head B serves to supply the liquid under pressure to the radial holes of the spray-head and to force the same throughall the holes, so as to' produce a very effective spraying action in the liquid.

The upper part of the reservoir A, which is filled with'carbonic-acid gas under pressure, is connected by a pipe d-with a gas-supply provided with a pressure-reducing valve D of anyapproved construction and at each side of the same with a pressure-gage D that indicates the pressure of the gas respectively in the reservoir and in the supply-pipe D after the same has passed through the pressure-reducing valve D. The outlet-pipe d is also connected by a second pipe D with the storage-tank'E for the surplus carbonic-acid gas, the pipe D being provided with a blow-ofi-valve D, that ii is set to certain pressure and that blows ofl.

a certain quantity of gas whenever this pressure is reached. The gas-supply pipe D is connected by a valve G with a switch-pipe G which is again connected by a flexible pipe with the inlet-pipe of the fountain to be charged. From the bottom of the reservoir A extends a second pipe f, which communicates, like the gas-supply pipe D, by a. valve G with the switch-pipe G". A third valve G, intermediately between the valves G and G, connects the switch-pipe G? with the storage-tank E. The valves G and G, by which the carbonic-acid gas and the carbonated liquid are respectively supplied to the "fountain, are shown in Fig. 5, and are arranged with springactuated spindles g andsnitable st ufling-boxes g for the same. The outer ends of the spindles g. are provided with rounded-off heads g that are engaged by a pivoted lever H, which carries a segmental cam k, that serves to engage either the head of the spindle of the valve G or the head of the spindle of the valve G,

according as the cam his placed above one spindle or the other, so as to supply either carbonic-acid gas or carbonated liquid to the fountain, as required. A third valve G is also provided with a spring-actuated spindle g, the head of which is arranged somewhat below the level of the heads of .the spindles g and g, and engaged only when a wedgeshaped slide-piece h, that is shown in Fig. 2 and which is guided at the under side of the lever H and operated by a, spring-actuated handle H is moved outwardly by said handle, in which case the slide-piece engages the rounded-off head 9 of the valve G and" presses the same in downward direction, so as to open the latter. The intermediate valve G is connected at its lower part by a pipe D with the storage-tank E and acts as a so-called snifting-valve, by which the surplus gas'that is compressed at the upper part of the fountain while it is charged is drawn or snifted off into the storage-tank. The shifting-valve G is provided at its lower part with an auxiliary-valve g and valveseat, said valve being spring-cushioned and serving to discharge the surplus gas in the fountain only when the pressure of the same overcomes the tension of the cushioningspring g The fountain is supported on a suitable platform P, which is attached to the upper end of a spindle p, that is guided in a hollow standard P and supported on the end of a fulc'rumed balancing -lever L, having two weights w w, which are so adjusted that one balances the weight of the empty fountain, while the other serves to balance the weight of the carbonated liquid charged into the fountain, so that a uniform quantity of liquid is charged into each fountain. On a bracket-support P at the lower part of the standard P are supported the casings of the crank lever L so that the latter strikes against the lever H and moves the same off the spindle of the liquid-supply valve G, so as to close the latter and shut ofl of the supply of carbonated liquid. This automatic shutting ofi of the liquid-supply valve G can also be accomplished by diiferent mechanisms. The means for balancing the fountain and automatically closing the supply-valve when the required quantity of liquid is charged into the fountain are well known and form no part of my invention The lever H- can 'also be operated by hand, as by little practice the fountain can be charged withthe required quantity of liquid, upon which the supplyvalve is closed.

The operation of charging the fountain is as follows: The fountain is placed in position on the platform P and its inlet-pipe connected by the flexible pipe with the switch-pipe G The valve of the inlet-pipe of the fountain is placed inopen position. The gas-supply valve G is then opened by placing the lever over the same and the fountain filled with carbonic-acid gas. This gas is under lower pressure than the carbonated liquid in the reservoir A. Consequently when the lever H is placed on the supply-cock G, that is connected with the reservoir, the'carbonated liquid is forcedinto the fountain against the pressure of the carbonic-acid gas in the same,which is compressed until an equilibrium of pressure between it and the pressure of the carbonated liquid is established. This counterressure of the carbonic-acid gas in the fountain prevents in a reliable and effective manner the release of any carbonic-acid gas that was in-- storage-tank E2 As soon as the shifting off of gas in the liquid. To produce the almost complete filling of the fountain with liquid, it is necessary to discharge the surplus q-uan tity of gas in the upper part of the same, which is accomplished by opening the socalled snifting-valve G by which the surplus gas is drawn off and conducted into the of the gas is accomplished the liquid-supply cock G is opened again and the space at the upper end of the fountain filled with carbon- ,ated liquid that has lost but a small quantity of the gas with which it was impregnated during the carbonating process While it Was charged into the fountain. When the fountain is filled, the valve of the inlet-pipe is closed,'tho flexible pipe which is connected with the stationary pipe (l disconnected, and the fountain removed. placed on the platform and filled in the same manner, and so on. As the shifting-valve G is constructed in a somewhat-different manner from the charging-valves G G, the surplus gas in the upper part of the fountain is conducted off only when its spindle g is depressed and its main and auxiliary valves opened. The tension of the spring of the auxiliary valve g of the shifting-valve is so adjusted that the surplus gas in the fountain is only,discharged when it is at a higher pressure than the counter-pressure of the valvespring. the valve closes and prevents the discharge of-the gas to the storage-tank. The result is that the fountain is never entirely filled with carbonated liquid, but that a small space is left in the same, in which carbonic-acid gas under pressure is retained, as it is not advisable to draw or snift elf all the carbonic acid in the same.

The advantages of my improved apparatus are, first, that the fountains can be charged through one valve-inlet opening with alarger quantity of carbonated liquid than hereto- 'fore; secondly, that the carbonic-acid gas incorporated into the liquid is retained by the same and very little of the same liberated from the liquid during the charging process; thirdly, that a uniform quantity of carbonated liquid is supplied-to the fountains and the supply automatically interrupted when the determined quantity is supplied to the fountain, and, fourth-1y, that by the adjustment of the weights on the balance-lever any size of fountain can be readily charged with the required quantity of liquid.

Having thus described my invention, I claimas new and desire to secure by Letters Patent' 1.
