l Claims.
The present invention pertains to a novel cooling apparatus for beverages and the like. The primary object of the present invention is to provide a beverage cooling apparatus, suitable for use in dispensing beer and the like, wherein all parts are readily accessible for the purpose of cleaning the same. More particularly, the invention provides a tank, adapted to be submerged or partially submerged in refrigerant, the tank t associated therewith for the purposeof connecting it to a source of supply and to a dispensing faucet, and in combination therewith is provided a novel valve arrangement for operating a signal to automatically indicate that the supply source is about to be exhausted.
Another object of the present invention is to provide a cooling tank `with a valve mechanism for operating a signal, the said valve mechanism and signal being permanently associated with a 0 removable head or cover plate whereby upon removal of the head for the purpose of cleaning the tank the valve mechanism is entirely removed therefrom so that it may be thoroughly cleaned.
Stil another object of the invention is to provide a liquid cooling tank with a double acting vvalve mechanism which functions to operate a signal device, andas a whistle, when the liquid level therein becomes low as a result of an exhausted supply source and which functions to provide a relatively large opening for the escape of air from the tank when the latter is empty or nearly empty and is being filled with liquid from a new supply source. e
With the above and other ends in View the invention consists in matters hereinafter set forth and more particularly pointed out with reference to the accompanying drawings, in which Figure 1 is a vertical cross section of the device;
Fig. 2 is a fragmentary vertical cross section illustrating another stage of operation;
Fig. 3 is a vertical cross section taken on a plane Y at right angles to Fig. l;
Figs. 4, 5, and 6 are cross sections taken respec- Like characters of reference are employed throughout to designate corresponding parts.
.The numeral I designates a cylindrical tank closed at the bottom as indicated at 2. Permanently secured to the upper end is a flanged collar 3 receiving thumb screws 4 for removably securing a cover plate 5 thereon. Intheflangedcollar 3 is mounted a packing element 6. Adjacent to the upper end of the tank is provided a nipple 5 'l which is adapted to be connected, in a manner Well known in the art, to a key or barrel containing the beverage to be cooled. Connected with the nipple 1 is a tube 8 which extends downwardly so that its outlet end 9 is disposed in close proximity to the bottom of the tank l. Slightly spaced downwardly from the upper end of the tube 8 is provided an outlet port I.
An outlet port I I is provided in the tank l, preferably close to the bottom 2, and has a tub-e I2 extending upwardly therefrom outside of the tank and provided with means I3 for attaching a pipe line thereto for conveying liquid from the tank I to a dispensing faucet, the latter not being shown here.
A pair of spaced apart rods I4 have their upper ends secured as at I5'in the coverplate 5 and secured to their lower ends is a cross bar it. Slidablyreceived in an aperture in the cross bar I5 is a valve stem Il having a valve i8 on its upper end slidably received in a valve nipple I9 on the cover plate. Secured on the valve nipple IQ is a hollow fitting 20 containing a valve seat 2l with which the valve I8 cooperates. The fitting 2t has an exhaust port 22 anda whistle 23 is connected to the exhaustport. The bore in the valve nipple I9 in which the valve I8 is received is provided with lengthwise extending grooves 24 so that air (under pressure as will hereinafter appear) in the tank Imay pass through the grooves 2lto enter the hollow fitting 2U but is prevented from escaping from the fitting through its exhaust port 22 by seating of the valve I8 on the valve seat 2|. In order to maintain the valve I8 against the seat 2l a spring 25 is mounted on the cross bar I6 to engage the adjustable elements 26 to resilientllT urge the valve stem I1 upwardly to thereby seat the valve I8.
Adjacent to the upper end of the valve stem Il is provided a fixed head 21 having levers 28 piv oted at 29 therein. The upper ends of thelevers 28 are provided with cam parts 3!) adapted to engage the bottom surface of the cover plate 5 so that when the levers are in the position shown in Fig. l they permit spring 25 to seat the valve I8 and when they are in the position shown in Fig. 2 they force the head 21 and stem Il downwardly, thus compressing spring 25 and unseating valve The spring 25 is constructed sufficiently i strong so that, in the absence of pressure on the levers 28, it will cause the levers 28 to move from the position shown in Fig. 2 to that shown in Fig. l and will normally maintain them in the latter position.
The means for applying pressure on the levers 28 to cause them to unseat the valve,Y I8 comtoY prises a float 3| which is slidably mounted, as a matter of convenience, on the valve stem The iioat 3| has a tubular extension 32 carrying a pair'of cam arms 33 adapted to cooperate with pins 34 on the free ends of the levers 28. The cam arms 33 function when the float 3| lowers by engaging the pins 34 so that the weight of the oat causes the levers 28 to pivot from their position of Fig. 1 to that of Fig. 2 wherein the valve |8 is unseated.
The valve |8 has an axial bore 35 which is in constant communication with the outlet port 22 regardless of whether the valve I8 is seated or unseated. The bore 35 communicates with a valve seat 36 in a valve chamber 31 containing a sliding valve 38. A coiled spring 39 is mounted in the valve chamber 31 and normally urges unseating movement of the valve 38. A lever is pivotally mounted so that its upper end engages the valve 38 and its lower end cooperates with a cam 4| carried by the float 3|. When the cam 4| engages the lever 40 as in Fig. 3 the the lever is rocked so as to seat Valve 38 and when the float 3| is lowered so that cam 4| is out of engagement with lever 40 the spring 39 forces valve 38 away from the valve seat 36.
In describing the operation it will be assumed that nipple 'l is connected to a source of supply, such as a barrel and means for applying air pressure to the liquid in the barrel to cause it to ow into the tank i. In as much as barrel tapping apparatus for supplying liquids to coolers is well known in the art the same has not been shown here. As the liquid begins to enter the tank it is necessary to exhaust the air therefrom and in the present case the float 3| will be positioned as in Fig. 2, the valve I8 will be unseated, and the air escapes through the grooves 24 and outlet port 22. Air may also escape at this time through valve chamber 3l and bore 35. As the tank is filled the liquid lifts the float 3|, the spring 25 seats valve |8, and the cam 4| engages lever 48 to seat valve 38.
The cam 4| is made sufciently long that a certain amount of fluctuation in the liquid level may take place without allowing lever 48 to pivot and permit opening of the valve 38. However, when the liquid level drops beneath a predetermined point valve 38 will be unseated and the whistle 23 will function to signal the fact that the liquid level is getting low. If the liquid level continues to drop valve I8 will be unseated and a greater volume of air will be permitted to escape from the tank. This latter feature has utility in that the rapid escape of air while the tank is being lled s desirable.
Although a specic embodiment has been shown and described it will be understood that various changes may be made within the scope of the claims without departing from the spirit of the invention, and such changes are contemplated.
