CARBONATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 639,631, dated December 19, 1899.

Application led March 27, 1899.

To all whom t may concern.'

Be it known that we, LEONARD TUFrs, of the city of Medford, and HEBER A. HOPKINS, of the city of Cambridge, in the State of Massachusetts, have invented a new and useful Improvement in Carbonating Apparatus, of which the following is a specification.

Our invention is especially designed for manufacturing soda-water in drug stores and ro similar places; but it may be used in bottling establishments and elsewhere.

The object 0f the invention is to provide for a constant and continuous supply of soda- Water automatically; and the invention consists in the features and combinations hereinafter described and claimed.

In the accompanying drawings, Figure lis a side elevation of our improved 'carbonator; Fig. 2, a plan view taken on line 2 of Fig. l

zo with parts shown in section; Fig. 3, a detail View, partlyin section, taken on line 3 of Fig. 2; Fig. 4, a sectional view taken on line 4 of Fig. 5; Fig. 5, a transverse sectional view taken on lines 5 of Figs. 3 and 4.; Figs. 6 and z 5 7, detail sectional views taken on lines 6 and 7, respectively, of Figs. 2 and 8; and Fig. 8, a plan sectional view taken on line 8 of Fig. 6.

In constructing our improved carbonatiug apparatus we use a receiver or mixing vessel 3o A and mount the same on one end of a rocking or tilting platform B, on which platform. and its supports most or all the other working parts are mounted. This platform has two pivots b, one at each side, which rest on a bearing b in the upper end of each standard C, forming the support thereof. We prefer to have these pivots of knife-edge form; but other forms may be used, if desired.

A hydraulic or other motor D, with a pump 4o E, is mounted on the end of the rocking platform opposite the end carrying the mixing vessel. A Water-supply pipe d connects with the union or coupling d of the motor, and a discharge-pipe d connects with the union or coupling d3 and has a union or couplingA d5, supported by an arm b2, for connecting a pipe discharging into a sewer or elsewhere. A tube e connects with a union or coupling cl2 of the supply-pipe d and witha union or coup- Serial No. 710,611. (No model.)

ling eon the pump-chamber, and a discharge- 5o pipe 'e3 connects with a check-valve e2, which in turn is connected with the pump and leads to the mixing vessel, a filter etbeing interposed in the pipe.

The standards C, through the frame or 5 5 bracket C', support a valve-casing F, the chamber of which is provided with an inletpipef, supplied by a pipe f2, which is connected with the street-main or other source of water-supply, and an outlet-pipe f leads 6o from the valve-chamber andis connected with the supply-pipe d of the motor. A valve G, havin ga series of radial openings g, separates the induction from the eduction portion of the valve-chamber, and this valve has a stem g', the inner end of which fits .a socket g2 in the hub of the valve and projects beyond the valve, being supported in a cross-bar g3 of the casing. The valve-stem is provided with a flanged shoulder g4, between which and the 7o cover F of the valve-casing is placed a suitable packing. The outer end of the valvestem has secured thereto au arm c, the free end of which passes between lugs c on the platform, so that the rocking of the platform causes the lugs to come in contact with the arm @and open and close the valve, thus regulating the water-supply.

The top of the mixing vessel is provided with a plug H, preferably having the con- 8o struc-tion shown in Figs. 6, '7, and 8, with four passages or holes. As shown, one of these passages or holes 7L communicates with the coupling h for the attachment of the liquidsupply pipe e3, and the opposite one receives a discharge-pipe I for the carbonated liquid. This discharge -pipe communicates with a coupling ,to which is attached a draft-pipe 7l', forming a continuation thereof, which in turn is provided with a safety-valve J, con- 9o trolled by a leverj and a weighty, as usual; and this coupling-pipe furnishes the attachment for a pipe leading to therdispensing apparatus. The plug H has a vent opening or passage m, controlled by a thumb-screw valve m', and also a passage 6, communicating with a coupling Z5 for the attachment of the gassupply pipe of the equalizing-valve.

A tube or cylinder K, containing liquefied carbonio-acid gas is removably supported on a board N and held in place by means of hinged straps K or in any other suitable manner, and on this board is placed an equalizingvalve L, held in position by a strap L' or otherwise. The gas-cylinder has a valve 7.a, and leading from this valve is a pipe t, connected with the coupling k2 of the equalizing-valve, for supplying gas to the valve, and the equalizing-valve has a regulator stem or key and a discharge-valve Z', connected with which is a pipe Z2, leading to a coupling Z3, support-ed in an arm b2, from which coupling` a pipe Z4 leads to the coupling Z5 for supplying gas through the passage l to the mixing vessel. This passage l communicates with a pipe (not shown) extending into the mixing vessel preferably down to near thebottom thereof. The equalizing-valve has connected therewith a pressure-gage M, by which the pressure at which it is set is indicated. The regulator is set by the hand-screw in its lower part.

Theliquidintroducedinto theinixing vessel to be charged is forced by the pump through the passage h into tubes h2, havin g laterally and inwardly projecting nozzles h3, and by the impact of the two nozzle-streams against each other the liquid is broken or atomized into an exceedingly tine spray. The tubes are connected with a head 71,4, having passages leading from a chamber therein, one to each tube, and the head is connected by a couplingr h5 with the passage h.

W'hen the apparatus is set up for use in a drug store, the supply-pipe f2 is connected with the hydrant or other source of supply and the `draft-pipe i with the dispensing apparatus and when it is set up for use in a bottling establishment connections are made accordingly. Either liquefied gas or gas from a generator may be used, as desired.

In operating the apparatus the regulator is set by means of a hand-screw to the p ressure desired, which will be indicated on the pressure-gage. the mixing Vessel, the water from the hydrant or other source of supply is turned on and the apparatus is ready for the operation of charging Water with gas. l At the commencement of the operation the rocking platform is in the position shown in Fig. l, with the mixing Vessel raised, in which position the water-supply passes through the induction or controlling Valve and the supply-pipes to the motor and pump-chamber. This starts the motor to operate the pump and force water into the mixing vessel, the water being divided or atomized, as above described, and desc-ending to the bottom of the mixing vessel, receiving in its descent carbonio-acid gas to the amount desired, and thus becoming fully charged or saturated. The charged water gradually fills the mixing vessel until the supply reaches a point where the weight overcomes the weight of the motor and pump, when the platform will be rocked or tilted When this pressure is reached in` down at the end supporting the mixing vessel. ThisV rocking or tilting, operating through the mechanism above described, closes the controlling-valve, and this stops the action of the motor and pump and shuts off the supply of water or liquid to the mixing vessel.

The drawing oft' from the mixing vessel of the charged liquid at the dispensing appara tus lowers the quantity in the mixing vessel and when a sufficient quantity has been withdrawn to allow the weight at the pump end of the platform to overbalance the weight at the opposite end the platform is reversely tilted, the controlling-valve opened, and the motor and pump again started to force a supply oi liquid into the mixing Vessel. This alternate stopping and starting of the pump occurs with each filling ot' the mixing vessel to its limit and each discharge therefrom to the extent necessary to make the Weight less than the weight at the pump end of the platform.

The supply of gas to the mixing vessel is automatic after the first starting and through the equalizing-valve is regulated to the pressure desired. The supply of liquid to the mixing vessel is also automatic bythe operations of the controlling valve above described, aud the result is that the supply of both gas and liquid is at all times automatically controlled and regulated, never requiring the attention ot" an opera-tor after the first starting and securing uniformity in the product.

The arrangement for s u p plying water shown in the drawings is intended for an ordinary hydrant-supply; but the apparatus may be used for charging mineral or other waters generally. All that is required to adapt it to this use is to disconnect the supply pipe of the pump from the hydrant supply-pipe, and connect it with a tank containing the mineral or other water which it is desired to charge, other slight changes being made to suit special conditions.

As mounting the parts on a rocking or tilting platform, as above described, constitutes the most essential feature of our invention, it will be understood that we do not intend to limit ourselves to minor features or details of construction. On the contrary, we contemplate formal changes and the omission of parts or the use of equivalents, as circumstances may suggest or render expedient. In this view it will be understood that While we have described our invention somewhat minutely with reference to details we do not intend to be limited thereto, except as pointed out in the claims.
