This invention relates to combined liquid dispensing and display devices, and has particularv reference to improvements in devices of this kind which include means to effect a constant circulation of the liquid through a transparent display container.
Devices 'of the foregoing type are particun larly adapted tothe 'display and dispensing of beverages, and to this end it has been the practice heretofore to provide a storage receptacle, suitably cooled, to contain the mainbody of beverage, and to effect a constant circulation of beverage from said storage receptacle through the display container and back to said receptacle.
Under the' foregoing conditions, if the display container is in any way subjected to heat, it is manifestthat the Vbeverage in its passage through said container will. ab-Y sorb heat and that an added burden will be imposed on the cooling apparatus to maintain the liquid in the storage receptacle at a desired temperature. Moreover, if the beverage is dispensed afterpassing into or through the display container and prior to its return to the storage receptacle, it may become too warm to constitute a satisfying drink despite the fact that the beverage in the rstorage receptacle may be maintained at a very low'temperature. Accordingly, it is an important object of the present inventiony to provide means whereby a part of the beverage from'the storage receptacle may be circulated through the display con tainer independently of the main body Vof beverage, thus to relieve the cooling apparatus of the burden of extracting heat absorbed by the beverage in its passage through the display container. ln connec-k tion with such an arrangement it is also a purpose to provide for conveniently directingV beverage being circulated'through the display containerv into thestorage receptacle and to enable a fresh supply of beverage to be drawn from theV storage receptacle for circulation through the display container.
Another purpose of the. invention is t0 provide vmeans to circulate beverage from the storage receptacle to aV dispensing sta#` tion and back to the storage receptacle independently of the display circulation, whereby .theungredients of the beverage will be maintained thoroughly mixed together and `whereby that portionof the beverage which is dispensed from time to time will be of substantially the same temperature. as the beverage in the storage receptacle.
For cooling the beverage in the storage receptacle suitable refrigeration apparatus is employed inclusive ofa cooling coil or coils positioned against the'outside of the storage receptacle, and it is a further purpose of the invention to provide means to assure and maintain good heat radiating contact of saidcoil with said receptacle.
Further, it is a purpose of this invention to provide a beveragedispensing and display device having the characteristics mentioned, which is simple in construction, relativelyinexpensive to produce and operate, durable, compact and thoroughly reliable and efficient in use. c
lWith the foregoing and other purposes in view, the inventiony consists in the novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, -illustrated in the accompanying drawings and delined in the appended claims.
ln the drawings, wherein lilrecharacters of reference :denote ycorresponding parts in the different views :l y y Fig. l isk a vertical .section through a beverage dispensing and display device embodyingthe novel features of the invention; and 4 lig, 2is a detail sectional view illustrating an alternative arrangement from that shown in Fig. l for controlling iiow of beverage from the cooling receptacle to the display container.
Referring now to the drawing in detail, it will be observed that the present device includes essentially a storage? receptacle A. for the beverage to be dispensed and displayed, refrigeration apparatus illustrated 'conventionally at B for cooling the beverage within receptacle A, and a display container C through which beverage from the storage receptacle is adapted to be lated.
Display container C consists of a hollow, transparent body of any suitable or pre- `erred design supported upon a base 11 and having an opening 12 formed in the bottom thereof through which a tube 13 eX- tends, suitable sealing means such as gaskets lll being provided to insure against leakage of beverage from body 10 past said tube through said opening 12.
rlube 13 is connected in any suitable manner at its lower end, outside of body 10, with a casting 15 which has al pair' of Vseparate passages 16 and 17 formedV therethrough, said tube being in communication with one of said passages and the other eing in communication with a pipe 18 which is arried by said casting and extends upwarl y through said tube into body 10, communication between said tube and said bor y being established in any suitable manner,.as, for example, by means of apertures 19 formed in the side of the tube.
Connected with passages lf3 and 17 are beveragev feed and return pipes V20, 21 respectively, connected `with one another and with the storage receptacle A atY or nearV the circubottom of the latter by a pipe 22.
Interposed at any suitable point in'feed pipe 2O or in pipe 22, between the pipes 20, 2'1, is a pui ip 23 adapte-d to be'driven in any suitable manner as, for example, .by an electric motor (not shown) to force beverage from pipe 22 through pipe 20, while interposed in pipe 22, according to the embodiment of our invention illustrated in Fig. 1, is a paircf valves 24, 25, the first of which is located between pipes 20, 21 and the second between pipe 21 and receptacle A. Thus, upon opening of both valves 24e, 25, assuming pump to be in operation, it is apparent that beverage will be drawn from storage receptacle A and forced through pipe 20,passa0e 16 and pipe 18 into the hollow display body 10, and as is also apparent, beverage which is delivered to body 10 will gravitate therefrom through tube 13, passage 17, with which said tube is connected, and thence back through pipe 21 to pipe 22. ln this manner the. beverage circulating line consisting essentially of pipes 20, 21, 22, and the display container body 10 may be charged with any desired amount of beverage from receptacle A and When said line has been so charged it is manifest that upon closing of valve 25 the beveragewithin said line will continue to circulate inthe manner stated, independently of the beverage in receptacle A, so long as pump 23 is continued in operation. It is equally'manifest that upon closing valve 24 and opening valve 25, pipe 2O will be cleared of beverage and that substantially all of the beverage which was previously circulated independently of the beverage in receptacle A will gravitate back to said receptacle, so that by again opening valve 24 and subsequently closing valve 25 trie aforesaid circulating line may be charged with a fresh supply of beverage for circulation independently of the beverage in receptacle A. Thus, over any desired period of time a constant circulation of beverage through the display container may bemaintained without subjecting the refrigeration apparatus B to the burden ofextracting heat absorbed by the beverage in its passage through the display container."
instead of employing two separate valves 24e, for the purposes aforestated we may employ a rsingle three-Way valve 26 located at the junction of pipe 21 with pipe 22, as
shown in Fig. 2 of the drawings. Also, if desired, We may employ 'a stepped member 27 positioned within body 10 to impart a novel cascade-like flowing' effecty to beverage delivered from pipe 18 into body 10,'or, in'- steadv of member 27 we Amay employ any other suitable means to directthe flow of Vthe beverage from pipe 18 through body 10 in avpleasing or attention attracting manner. Y Y
For maintaining the beverage in receptacle A in a thoroughly mixed condition and for dispensing beverage from said receptacle, a Circulating line of piping independent of thel display line is employed. Y This line consists of a feed pipe 28 leading from a bottom portion of receptacle A to anv inverted U-shaped passage 29 formed in the castingl, and a return pipe 30 leading from said passage 29 back toa top portion of said receptacle. is a pump 31 which may bedriven by the saine motor or other source of power for driving 23, or which may havea `source ofv power individual thereto, the function of this pump beingl t'o circulate beverage from receptacle A through line 28, 29, 30 back -to said receptacle either constantly or over such periods of time as may be'dee'med necessary or desirable. By thus circulating said beverage` the return flow through pipe30is delivered' into Athe main body of beverage contained m receptacleV A under pressure developed by the pump I3l so that the bever-` age is maintained agitated and in a thoroughly mixed conditionv sov longas the pumpis vmaintained in operation.
YFor dispensinor beveragel from the circulating Vline 23-30 We employ'any suitable form of valve such as a spigot 32 tapped into said line at any suitable point, preferably at the point where said line makes a return bend, as at the passage 30, ,to assure beverage flowing from said valve under substantially the same pressure at'whieh it is circulatedvthrough said line; By covering pipes 28, 30 with suitableheat insulat- Interposed inpipe 28v Jos ing material it is clear that beverage dispensed from spigot 32 will be at substantially the same temperature as the beverage in receptacleA so long as a circulation is maintained through line 28-30.
Refrigeration apparatus B which may be of any suitable or desired type, is inclusive of a coolingcoil 33 disposed against and having metal-to-metal contact with the receptacle A. In order to maintain good heat conducting contact between said coil and said receptacle we' fill such spaces as may exist between the respective turns of the coil and between thecoil and the receptacle A with suitable heat conducting, non-corrosive material such as ordinary commercial solder as indicated at 34, said material serving to prevent corrosion from forming a heat insulating film between the coilr and receptacle or around the coil as is apparent.
l/Vithout further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that changes yin the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention and scope of the appended claims.
