Beverage dispenser unit
FIELD OF INVENTION 
     The present invention relates to beverage dispenser systems, and more particularly, provides a beverage dispenser unit which includes the requisite hydraulically driven pumps, conduit, adjustable regulator and other equipment for providing a useful unit to deliver, at a hand-held mixer dispenser, any one of several beverages with appropriate water mixture thereat. The water intake is provided not only to operate the several hydraulic pumps connected to external beverage units, but also provides a water supply for mixture at the hand-held mixer dispenser portion of the unit. 
     BACKGROUND AND BRIEF DESCRIPTION OF PRIOR ART 
     In the past, beverage dispenser units have been quite cumbersome, generally requiring electrical connections and having a series of operative units disposed at various locations. 
     No patent literature is currently known which bears directly upon the invention described in detail herein. 
     One purpose of the invention is to provide all the requisite structure needed in a single unit, and with an adjustable regulator being provided as well as a series of hydraulically driven pumps, the latter being driven by the intake water line pressure and also supplying the water passing therethrough to the manifold of the unit. The concept of including a series of water-driven pumps within a cabinet, the additional structure, and the method of operation of the unit, are deemed new. 
     BRIEF DESCRIPTION OF INVENTION 
     In the present invention, a cabinet is provided that is preferably made of metal and is rectangular in shape. A lid is provided for sealing off the cabinet. Contained within the cabinet and mounted to interior portions thereof are a series of hydraulic pumps, each having a pair of lines transporting, respectively, both beverage and water to a manifold mounted within the unit. A metal flex hose is coupled from the manifold to a hand-held mixer dispenser provided with suitable finger touch controls and also a dispensing nozzle. The unit likewise includes a nozzle retainer for releasably receiving the nozzle when the same is not directly in use. A manually adjustable pressure regulator is provided in the unit, is coupled to the intake water line, and delivers water under selected pressure to the several hydraulic pumps employed. The water line thus supplies both driving pressure to the pumps and also a water supply to the manifold for selective mixing with the various juices or other beverages directed thereat and coupled by other intake conduit, via the pumps, to beverage or beverage concentrate containers stored outside of the unit. 
     OBJECTS 
     Accordingly, a principal object of the present invention is to provide a beverage dispensing unit. 
     A further object is to provide a new type of beverage dispenser unit having included therein a series of pumps for accommodating the reception and transport of various liquids to dispenser apparatus, the water supply of the unit serving both to drive the pumps under selected pressure, and likewise to provide a water supply to the manifold of the unit for respective mixture with individual beverages pumped into the unit from the exterior. 
     An additional object is to provide a dispenser unit which can easily rest upon a countertop or shelf at a store or restaurant, for example, this without requirement of electrical connection, but merely a coupling to an external pressurized water supply. 
     A further object is to provide a dispensing unit including all of the apparatus needed for delivering and mixing the juices or other beverages of exteriorly positioned beverage supply, and this in the desired manner by use of a handheld mixer dispenser structure. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     The present invention, together with further objects and advantages thereof, may best be understood by reference to the following description, taken in conjunction with the drawings in which: 
     FIG. 1 is a perspective view, partially exploded, of a beverage dispenser unit constructed in accordance with the principles of the present invention 
     FIG. 2 is a diagram of the hydraulic system of the unit, illustrating the manner by juices or other beverages are drawn into the hydraulic pumps provided in the unit, and wherein water under pressure is also supplied and also pressure regulated such as to supply water not only to drive the various pumps but also to provide a water supply at the manifold preparatory to the mixing function. 
     FIG. 3 is an enlarged fragmentary detail, principally in section, and illustrating the structure whereby an external water supply can be coupled to the unit. 
    
    
     DETAILED DESCRIPTION OF PREFERRED EMBODIMENT 
     In FIG. 1, the beverage dispenser unit 10 is shown to include an enclosure or cabinet 11, generally made of metal, and having opposite sides and opposite ends together with a bottom as indicated. The rear end or rear panel 12 includes a series of apertures, four apertures 13-16, these being provided with respective grommets 17, for the receipt of intake conduit 38-41 leading from external beverage or concentrate containers, and also an aperture 17A for receiving a pressured water connection. This is seen in FIG. 3. Referring to FIG. 3, the intake water conduit 18 is pressed onto a step connector 19 that is threaded at 20 and includes a flange 21; FIG. 3 is thus a detail of the physical structure taken along the arcuate line 3--3 in FIG. 2. Nut 22 is threaded onto the threaded portion at 20 for retaining the connector in position and tightly secured to rear panel or end 12 of the rectangular metal cabinet. Portion 23 is provided and receives conduit 24 leading to pressure regulator 25. Pressure regulator 25 includes an adjustable control 26 which is manually adjustable and includes the handle 27 indicated. The output side of the pressure regulator at 28 leads to a four-way connection at 29 for providing water via conduit 30-33 to several hydraulic pumps 34-37. Conduit 38, 39, 40 and 41 lead from the respective juice or other beverage units 1-4 in FIG. 2 directly to the pumped-fluid inlets of their corresponding pumps 37, 36, 35 and 34, respectively. Thus, the pressured water serving as the driving fluid for each of the pumps 1-4 comes from outlets of the respective pumps 1-4, being conducted by respective conduit 42-45 to manifold 46, whereas the pumped liquid, i.e. juice, concentrate, or other beverage, is conducted from the &#34;juice&#34; units 1-4 via respective conduit 38-41, and passes as pumped liquid through the respective pumps 37, 36, 35 and 34 to be conducted by conduit 47-50 to manifold 46. 
     Pumps 1-4, designated by lead lines 61-64, are standard, off-the-shelf items and may comprise what are known in the industry as Shur-flo Brix pumps, each having a pair of inlets and a pair of outlets, a respective inlet and outlet being for the drive or pumping liquid, with the remaining inlet and outlet being for the pumped liquid. Manifold 46, in combination with metal flex hose 51, hand-held finger manipulated dispenser 52 with control buttons 53, and nozzle 54, comprises a standard dispenser system or structure 5 such as that known in the industry as the Wunder-Bar dispenser system, as manufactured, for example, by the Automatic Bar Controls, Inc. Cut-outs, such as that shown at 57, are provided cabinets 11 for the manifold 46 and nozzle retainer 55, the latter provided with nozzle receiving aperture 56; thus, the manifold and nozzle retainer can be flush mounted by screws, not shown, to the cabinet 11. Aperture 56 of the nozzle retainer releasably receives the nozzle 54 when not in use. 
     Screws 57 are provided for securing the individual hydraulic pumps to the inner opposite sides of the rectangular metal cabinet 11, as may be appropriate. Correspondingly, additional screws 58 provided for securing the lip 59 of lid 60 over the rectangular cabinet at representative apertures 61, 62 as provided. The juice or beverage containers #1-4 in FIG. 2, identified by numerals 61-64, are coupled, of course, to the beverage conduit 38-41 as shown. 
     In operation, the water supply is turned on and the pressure for pump drive regulated at pressure regulator 25. Actuation of the several pumps and selection of the various beverages can be effected by hand-held mixer dispenser 52, this for delivering the desired liquid or liquid mix at nozzle 54. When the unit is inoperative, then the nozzle 54 is simply replaced into the nozzle retainer at 55. 
     While particular embodiments have been shown and described, it will be obvious to those skilled in the art that various changes and modification may be made without departing from the essential aspects of the invention and, therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
