7 Claims.
This invention relates to a carbonating apparatus which is particularly adapted for the preparation of carbonated water for use at soda fountains, bars and the like. t
One of the main objects of the invention is to provide a carbonatingv device which is simple in construction, efficient in operation and which occupi-es very little space and which will efiectively mix. carbon dioxide and water in the proper proportions and which also does not require any moving parts which are likely to wear or get ou of order.
Another. object of the invention is to provide a carbonating apparatus of the character described by means of which water and carbon dioxide may be properly mixed without any specially designed agitating means.
a carbonator of the character described in which water and carbon dioxide are mixed in proper proportion and whichis provided with means for delivering the water and the gas to a carbonating chamber simultaneously and means for automatically maintaining the gas pressure and the water pressure substantially the same whereby efiicient carbonation will be obtained even though there be a wide variation in water pressure.
' A further object of the invention is to provide a method of making carbonated water in which the carbon dioxide gas ismixed with the water in the same proportions regardless of variations in the water pressure.
A still further object of the invention is to provide a carbonator of the character described which is of such a size that it may be located in the coolingtank usually found at a soda fountain or. bar.
Further and more limited objects of theinvem tion willappear as the description proceeds and by referenceto the accompanying drawings in which Fig. 1 is a front elevation of our improved carbonator; Fig. 2 is a view similar to Fig. 1 taken at right angles thereto; Fig. 3 is a vertical sec-- tional view of the carbonator shown in Fig. 1; Fig. 4. is an enlarged vertical sectional view of the should be dispensed with the highest possible gas content and at a temperautre of about 34 F. The carbonator should also be kept cool as the amount absorb the maximum amount of gas. Another object of the invention is to provide of carbon dioxide that the water will absorb is almost directly proportional to its temperature. The carbonator should also be located as near as possible to the cooling unit in the fountainand adequate storage capacity should be provided in the fountain cooling unit to insure the carbonated water remaining in the cooler long enough to become thoroughly chilled. This is especially true where there is a heavydemand for carbonated water. I
In our improved carbonator gas is admitted to the carbonating chamber through a porous stone as the water is delivered over the stone in a thin stream. The gas is blown through the water under such pressure as to break up the water into a fine mist or spray which enables the water to Our unit also embodies means for maintaining a gas pressure equal to the pressure at which the water is.
delivered to the carbonator. The water pressure ,in different localities may vary from 25 to sure of approximately pounds,v which is considerably in excess of the water pressure usually found. This does not mean that a 100-pound gas pressure is entering the carbonator but merely insures a gas supply at a pressure at all times considerably abovethe Water pressure. An additional gas regulating valve on the carbonator automatically controls the gas pressure entering the carbonator to the exact amount of prevailing water :pressure regardless of the fluctuation.
Referring now to the drawings, our carbonator consists essentially of a carbonating chamber which is designated generally by the reference character A and which consists essentially of a hollow casting l to which is threadedly secured a hollow tubular casing 2. The casting l is provided with a centrally disposed bottom opening l' above which is provided an annular depending shoulder 3 which is interiorly threaded. Tlireadedly secured in this threaded opening is a fitting 4 having a centrally disposed opening 5 therein. The lower endof the fitting 4 is provi ded with an annular shoulder 6 which receives through which the carbon dioxide is delivered and from which it is taken up and absorbed by the water passing over the surface thereof. The
member I and the casing 2 are preferably circular but may be of different shape, if desired. The porous member I is slightly smaller in diameter than the tubular casing 2 so as to leave a very small circular space 8 between it and the inner wall of the casing 2. Extending through the tubular member I is a tube 9 the upper end of which is threadedly secured to the top of the casting I and is in communication with an outlet bore or passageway Ill. The lower end of the tube 9 extends beyond the lower end of the porous member I and secured thereon is a circular block H which engages the lower end of the tubular member I and holds thesame in place, a gasket 2 being provided to prevent leakage at this point. Also secured over the threaded lower end of the tube 9 is a nut H! which engages the circular block II and serves to clamp the tube I in place. The nut I3 is preferably covered with a mass l4 of cement or plaster of Paris or other suitable material. The extreme lower end of the tube 9 terminates. a short distance above the lower end of the outer casing 2. The tube 9 serves as a means for withdrawing the carbonated water from the carbonating chamber although the carbonated water may be withdrawn through the bottom of the chamber if desired. The capacity of the delivery tube with respect to the water inlet is such that the casing 2 is always filled and the porous stone is always covered with water. A fitting I5 is secured in the outer end of the passageway l9 and is adapted to be con nected to a pipe leading to the draft arm at the fountain or bar.
At one side of the casting I there is provided a water inlet connection l6 which is threadedly secured therein. Threadedly secured in the connection 6 is a fitting |'I having a shoulder |8 at the lower end thereof over which is secured a downwardly opened opening check valve 9 which is known to the trade as a Thomas rubber check valve. Threadedly secured to the fitting II is a T 20 from which leads a connection 2| which connects with the water supply or main. The casting is also provided with a circular bore or passageway 22 which is in open communication with the space between the porous member I and the inner wall of the casing 2 so as to deliver a thin sheet of water over and about the porous member.
Disposed at the opposite side of the casting is afitting 23 which is threadedly secured therein and communicates with a bore or passageway 24 which communicates at its 'opposite end with the opening-5 in the fitting 4. Threadedly secured in the fitting 23 is a fitting 25 the lower end of which is provided with a shoulder 26 over whichis/ se- 5 cured adownwardly opening rubber checkvalve 21 like the check valve i9. Threadedly secured to the outer end of the fitting 25 is a gas regulator valve 28 which is shown in detail in Figs.
4 and 5, and to which is connected the gas supply line 29. A suitable regulator valve may be provided in the line 29 so that carbon dioxide gas will be delivered to the gas regulator valve 28 at a pressure of approximately 100 pounds.
The gas regulator valve 28 consists essentially of a casting which is shaped in section as shown most clearly in Fig. 4. The gas supply pipe 29 connects with an interiorly threaded boss 3| and the fitting 25 connects with an interiorly threaded boss 32disposed opposite the boss 3|. Extending inwardly from the boss 3| is a hollow extension 33 which is rectangular in section as shown in Fig. 5 and which is provided with a threaded opening in which is secured a fitting 34 having a bore or passageway 35 therein. The fitting 34 is provided at its outer end with a circular shoulder 36 over which is secured a cylindrical sleeve 31 having a plurality of ports 38 therein. Fitting within the cylindrical sleeve 31 and slide.- ble therein is a cylindrical plug 39 having an enlarged head 40. Surrounding the sleeve 31 is a coil spring 4| one end of which bears against the fitting 34 and the other end of which bears against the head 46 of plug 39 and urges the same outwardly or toward the left as seen in Fig. 4. The end of the plug 39 opposite the head 40 is provided with a recess in which is received a valve member 42 which engages a valve seat 43 provided on the; outer end of the fitting 34. Disposed within the casting 30 is a cup shaped member 44 to which is secured a sylphon bellows 45 to the outer end of which is attached a plate 46. The plate 46 is provided with an interiorly threaded boss 41 at one side thereof and a boss 48 at the opposite side thereof. Secured to the boss 41 is a yoke 49 having a pair of oppositely disposed legs 50 and 5| which extend around the tubular extension 33. Secured to the legs 50 and 5| is a plate 52 which is held in place by suitable bolts 53 and 54. Carried by the plate 52 is a cap 55 in which is threadedly secured a plug 56 which is disposed immediately opposite and adjacent the head 4| of the plug 39. The casting 39 is open at one side andis closed by means of a cap plate 51 which has an interiorly and exteriorly threaded boss 58 thereon. This cap plate is held in place by'suitable screws 53 and is provided with a threaded opening 88 which receives therein one end-'01 a pipe 6| the opposite end of which connects with a fitting 62 threadedly secured in the T 20. The threaded opening 60 is in open communication with the interior of the bellows 45 and the connection 8| provides a connection between the water supply pipe and the opposite side of the plate 46 of the regulator valve.
3 Threadedly secured in an opening provided in the boss 58 is a plug 62 the inner end of which is provided with a boss 63 and over which is secured a circular plate 64 which receives one end of a coil spring 65 the opposite end of which fits over and surrounds the boss 48 on the plate 46. The coil spring 65 is a compression spring and tends to urge the plate 46 toward .the left, as seen in Fig. 4. The outer end of the plug 62 is provided with a tool receiving slot 66 by means of which the plug may be turned to adjust the tension on the spring 65. Surrounding the plug 62 is a suitable packing gland 61 and a packing nut 68. Threadedly secured over the. boss 58 is a cap or cover plate 69 which is removable to permit adjustment of the plug 62.
It will be seen that by reason of the connection 6| the water pressure will be exerted upon the plate 46 which tends to move the same toward the left, as seen in Fig. 4. As this plate moves toward the left, the yoke 49 moves with it, which moves the plug 56 away from the head 40 of the plug 39. The coil spring 38 tends to move the valve plug 39 toward the left as seen in Fig. 4 and therefore to move the valve 42 from its seat to permit the carbon dioxide gas to flow into the gas regulator valve which exerts a pressure upon the opposite side of the plate 46. When the gas pressure exceeds the water pressure, the valve 42 will be moved to limit or cut off the delivery of gas seen that by adjusting the plugs 56 and 62, a
balanced condition may be obtained between the water. pressure and the gas pressure delivered' through the fitting 25 so as to always maintain a gas pressure equal to the water pressure. Should the water pressure decrease the pressure of the gas on the opposite side of the plate 46 it will tend to close the valve to decrease the flow of gas through the bore 35 thereby always maintaining a balanced condition of gas pressure and water pressure. The plug 56 and the plug 62'' are adjusted to obtain a proper balanced condition when the device is installed. The carbonated water is drawn off through the bore I and connection l which is connected with the draft arm or carbonated water dispensing outletat the fountain or bar. The entire unit is of such a size that it may be readily placed in the cooling unit immediately adjacent the fountain or bar, although thecapacity of the carbonating chamber and the connections leading therefrom are such as to maintain a suitable amount of carbonated water which will be kept cool. Even though the draft arm may be left open a sufficient amount of carbon dioxide will be admixed with the water as it enters the carbonating chamber to supply carbonated water containingfrom 2 1; to 4 volumes of carbon dioxide gas, which is in excess of the maximum required.
It will now be clear that we have provided a carbonator which will accomplish the objects of the invention as hereinbefore stated and which will function efiiciently and automatically regardless of the variation in water pressure. It is-to be understood that the embodiment of the invention herein disclosed is merely illustrative and is not to be considered in a limiting sense as various changes may be made in the details of construction without departing from the spirit of our invention as the invention is limited only in accordance with the scope of the appended claims.
