United States Patent 3,380,629 BEVERAGE DISPENSING APPARATUS Joseph Kontra, Northridge, and Gerald F. Crate, Woodland Hills, Califi, assignors, by mesne assignments, to Gerald F. Crate, Woodland Hills, Calif.
Filed Nov. 4, 1964, Ser. No. 408,818 12 Claims. (Cl. 222-26) The present invention relates to the dispensing of liquids, and more particularly to an improved apparatus for positive and remote control of such dispensing.
Certain liquids require special handling, especially when dispensed through a tap or faucet. A carbonated beverage, for example, is particularly sensitive and volatile because carbon dioxide is placed in solution under pressure. Any agitation creates turbulence and causes it to etfervesce and become float, resulting in a loss of taste. Agitation is caused by several factors, primarily by obstacles disposed in the path of flow of the beverage from a source through a faucet and to a container, the foremost obstacle is the valve which, of necessity, cannot be dispensed with. Consequently, various valve mechanisms have been devised to minimize fluid turbulence as the beverage passes through the valve.
A conventional valve is operated manually by a handle. A disadvantage to this system, with respect to turbulence, is that, if the valve is not opened rapidly, this causes an uneven flow rate. This varying rate of flow increases turbulence and, consequently, promotes elfervescence. Other systems have been designed to overcome the rate of flow problem; however, they have not been entirely successful since they may be of complicated design or of high cost, for example.
The position of the valve with respect to the faucet also affects the beverage. In many conventional applications the valve is displaced a distance from the faucet and a conduit of appreciable length is required to be disposed between the valve and the faucet. In between openings of the valve, this conduit becomes a reservoir or trap in which the beverage, which has already partially effervesced due to the agitation as it passed through the valve, becomes flatter and less tasty. Over a short period of time, a beverage such as soda or beer also partially deteriorates to effect a deleterious change in taste. This beverage in the conduit, upon a subsequent opening of the valve, either is poured into a glass with fresh beverage or must be thrown out to avoid contamination therewith.
The relative position of the valve and the faucet presents also a cleaning problem. It is necessary to clean the dispensing apparatus periodically to remove stale and decomposed beverage for sanitary as well as taste purposes. The design of conventional apparatus does not lend itself to easy cleaning.
Conventional apparatus, including the manual-handleoperated valve and the valve displaced from the faucet, lends itself to substantial waste. In the latter case, it is most often necessary to dispose of the beverage trapped in the conduit or reservoir before pouring fresh beverage. When a handle-operated valve is employed, a container may be overfilled with a foaming beverage such as beer so that too large a head is created. Such excess foam must be scraped from the top of the filled contained. In addition, the operator of the faucet, e.g., a soda jerk or a bartender may utilize the conventional apparatus to give out free samples, generally for tasting purposes or engage in outright pilferage since no means are provided for recording the amount of beverage dispensed.
Prior apparatus also is disadvantageous since it allows an operator to fill but one container at a time. While holding the container under the faucet with one hand, he must operate the handle with the other. At peak dispensing hours, the procedure can consume an inordinate amount of time and, possibly, create disgruntled customers.
These disadvantages are overcome by our invention and corresponding advantages will become apparent from the following description thereof. A faucet, having a through bore, is provided with a spout communicating therewith. One end of the bore communicates with a source of beverage to provide a conduit from the source through the one bore end and the spout. A valve seat having a gasket is formed at this end. A valve member is disposed Within the bore and is terminated by an enlarged head which is in sealing engagement with the valve seat. An extension is secured to the other end of the valve member and projects outside the other end of the bore. A pair of diametrically opposed slots are formed on the extension. A solenoid assembly for operation of the valve member is secured to the faucet. The assem bly includes an electromagnet having an axis. An armature or core is disposed coaxially adjacent the electromagnet. When the electromagnet is energized, an electromagnetic force is exerted upon the core for rapid movement thereof toward the electromagnet. A spring is also disposed along the axis in contact with the core to provide a bias on the core in a direction opposite to, and less than, that of the electromagnetic force. A yoke at one end is secured to the armature. A two-pronged fork is formed on the other yoke end to engage the extension within the slots. In operation, when the electromagnet is energized, the core suddenly moves toward the electromagnet under influence of the force, against the bias of the spring, in order to unseal the valve head from the valve seat in a positive and speedly manner. When the electromagnet is de-energized, the spring bias quickly urges the core away from the electromagnet and the sealing engagement between the valve head and the seat is re-established to terminate fiow of beverage from the source through the spout.
The electromagnet is energized and de-energized by an electronic apparatus including a timer, which regulates the length of time electrical energy is supplied to the electromagnet, and a counter, which is calibrated in terms of the amount of beer flowing from the source through the spout. A foot pedal operated switch is connected in series with a relay winding of a relay switch, a pair of normally closed cam operated switches, and a volt power source. The relay switch includes a pair of contacts one of which is disposed in parallel with the foot pedal switch. When the foot pedal switch is momentarily closed, the winding is energized to close the relay contacts one of which is substituted for the pedal switch upon the opening thereof to maintain the relay winding energized. The remainder of the electronic circuit then functions automatically until one of the cam operated switches opens to de-energize the relay winding and, consequently, to open the relay switch. The circuit further includes two conventional cam operating timer motors each controlling each of the cam switches, and two conventional counters secured in parallel with the timer motors. A selector switch is secured to both timer motor-counter parallel circuits for selective operation thereof. Primary windings of a pair of transformers are connected in parallel with the selector switch circuit. The circuit also includes the secondary windings of the transformers, a rectifier, the solenoid electromagnets of both faucet assemblies, and a second selector switch for selective operation of either of the electromagnets. For illustrative purposes, it will be assumed that one timer motor ope-rates for a period of time sufficient to fill a glass with a beverage while the other timer motors period of time corresponds to the filling of a pitcher. With both selector switches set for operation of a particular timer motorcounter circuit and for operation of a corresponding electrornagnet and with the relay winding having already been energized, current will flow through the various circuits to operate the selected electromagnet which, in turn, allows a beverage to flow through the selected faucet to fill the glass. At this time, the particular counter operates to register the fact that the glass is being filled. The glass timer motor continues to operate until its cam rotates to open its cam operated switch. At this point, the glass is filled and the relay winding is denergized to open the relay switch and to cut off the power.
It is, therefore, an object of the present invention to provide improved beverage dispensing apparatus.
Another object of the invention is to provide a dispensing apparatus having a positive and quick response.
A further object of the invention is the provision of a dispensing apparatus of simple construction.
Still another object of the invention is to provide for eificient control of beverage dispensing.

Although it is to be understood that our invention relates to any beverage dispensing device, the following description is directed to the dispensing of beer as an illustrative example.
With reference to FIG. 1 an apparatus 10, a dispenser of draft beer, includes two faucet assemblies 12 and 14 of identical design, each being constructed in accordance with the invention. Assemblies 12 and 14 are mounted on a pair of standards 16 and 18, respectively, which are secured to the surface of a bar 20. An advertising knob 22, which carries the brand name of a beer, is threadedly afiixed to each faucet assembly by means of attachments 24 (see also FIG. 2). Conduits 26 and 28 are secured between the faucet assemblies and a beverage supply 30, which, for the sake of convenience, is illustrated as standing below the bar. Standard 18 has been partially cut away to disclose conduit 28 and other elements disposed therein. Conventional refrigeration and pressure apparatus has been omitted from the drawings since they do not form a part of the invention. As illustrated, faucet asembly 12 is used to fill glasses of beer while faucet assembly 14 is used to fill pitchers; however, if desired, each faucet assembly may be utilized for filling both glasses and pitchers.
The faucet assemblies are connected to an electrical selector box 32 by means of electrical leads 34 and 36 and the selector box is connected by leads 38 and 40 to an electronic timing and counting circuit box 42. A foot 4 pedal operated switch or actuating switch 44 is electrically connected by lead 46 to circuit box 42. A wire 48 connects the various electrical equipment to a conventional outlet 50 through plug 51. Selector box 32, circuit box 42, pedal switch 44, and all associated leads may be referred to as an electronic operator or controller.
The selector box is provided with a selector switch operator 54 for directing the use of either faucet assembly and a pair of neon indicator lamps 56 and 58 for indicating which faucet assembly is to be operated. The circuit box is provided with a OFF-ON power switch 60, a glass counter indicator 62 for faucet assembly 12, a pitcher" counter indicator 64 for faucet assembly 14, a fuse 66 to protect the circuit and a power indicator lamp 68.
In operation, switch 60 is flicked to its ON position. Switch 54 is then set so that a selected faucet assembly may be operated as indicated by illumination of lamp 56 or 58. Upon closure of switch 44, the selected faucet assembly operates to allow a predetermined amount of beer to flow into a glass or a pitcher and the corresponding counter indicator records this event.
FIG. 4 depicts a cross-sectional view of faucet assembly 12, although the same following description would apply to assembly 14. The assembly comprises a faucet 70 and a solenoid 72. The faucet comprises a body 74 in the form of a bib-cock having a downwardly projecting spout 76 and a generally hollow cylindrical enlargement 78 provided with an entry 79. The body is formed with an axial bore 80 which extends therethrough and which has an inner end 82. The entry is of a greater diameter than the bore and is joined thereto by a bridging orifice 84. An annular gasket 86 is mounted in orifice 84 to form therewith a valve seat. Spout 76 is provided with a passage 88 which communicates with the bore at opening 90 to operate as the outlet for the bore. Conduit 26 communicates with the entry by a threaded connection 91 between the conduit and the enlargement. Consequently, a flow path is established by conduit 26, entry 79, orifice 84, bore 80, and passage 88.
A pair of breather tubes 92 and 94 are formed in the body to provide a gas relief among the bore, the passage and the exterior of the body.
Reciprocally mounted within the bore is a valve member 96 (see also FIG. 5) having a generally cylindrical end 98 disposed at an open end 99 of the bore, a bulbshaped enlarged head 100, and a relatively slender cylindrical neck or stem 102 which interconnects end 98 with head 100. A slot 104 is diametrically cut through the cylindrical end of the valve member. An extension 106 is affixed to cylindrical end 98 by bolt 108 and projects beyond open end 99. A pair of diametrically opposed key slots 110 are cut into the extension member. The extension is fixed in position with respect to cylindrical end 98 by bolt 108 to maintain a 90 disposition between the key slots and slot 104. As shown in a comparison between FIGS. 2 and 4, when valve member is reciprocated in the bore, breather tubes 92 and 94 are alternately joined in communication by slot 104.
Solenoid 72 is mounted on body 70. The solenoid includes a casing 112 which is fixed on body 74 and which is provided with an aperture 114 for electrical lead 34. A cover plate 116 is secured to the casing by screws (not shown). Disposed within the casing is an electromagnet 118 comprising a winding 120 enclosed within a container 122. The container is separated from the casing by an insulation material 124 which is selected for its heat and electrical insulating characteristics. Consequently, any heat generated by the winding will not be communicated to the body, thus preventing any raise of temperature of the beverage flowing therethrough. Moreover, the probability of an electrical short circuit is prevented.
The winding is disposed in annular configuration about a tube 126 which is provided with an axial cylindrical opening 128. Container 122 includes end walls 130- and 132 which fix tube 126 in place. An aperture 134 is formed in end wall 132. An armature or core 136 is reciprocally disposed within cylindrical opening 128 for movement toward and away from the winding. A spring 138 is disposed between end wall 130 and the core to provide a bias thereon in a direction away from the winding. A projection 140 is secured to the armature and extends through aperture 134 in order to communicate any reciprocation of the armature outside of the container. As shown in FIG. 4, the diameter of the aperture is less than that of the armature to prevent any movement thereof outside of the container under the biased urging of the spring.
A yoke 142 (see FIGS. 3 and 4) is attached at its upper end to projection 140 by screw 144. At its lower end the yoke is provided with a two-pronged fork 146 comprising tines 148. The tines are disposed to fit about the extension within key slots 110. Because of the parallel relationship of armature 136 and valve member 96 and the connection threbetween by yoke 142, the valve member cannot rotate, assuring the relative position of slot 104 with breather tubes 92 and 94.
:In operation, when the solenoid winding is energized,
armature 136 is drawn toward end wall 130 by the electromagnetic force thus aroused against the bias of spring 138. Because of the yoke connection to the end 98, valve head 100 is unseated from sealing engagement with gasket 86 of the valve seat. Beverage from source 30 thereby flows under pressure through conduit 26, the open valve, and passage 88. Upon de-energization of the winding, core 136 moves away from the winding under the bias of the spring to re-etfect a sealing engagement between the valve head and the orifice gasket to cut off the beverage flow. The winding of solenoid 72 of faucet assembly 12 and the corresponding solenoid of assembly 14 are operated and controlled by the electronic controller circuit shown in FIG. 6. The circuit may be said to comprise three smaller circuits 160, 162, and 164. Circuit 160 is an energizing circuit. Circuit 162 is a timing and counting or correlation circuit for controlling circuits 160 and 164. Circuit 164 is a valve solenoid operating circuit.
Circuit 160 comprises, in series with and connected by leads 48 to a 110 volt power source, power switch 60, fuse 66, a normally closed cam switch 166, a normally closed cam switch 168, a relay winding 170 and foot pedal or actuating switch 44. Indicator light 68, which comprises a neon lamp, and associated resistor 172 are secured in parallel with the switches and winding. A relay switch 178 is disposed parallely with pedal switch 44. When switch 60 is closed, power is available at foot switch 44 as indicated by the immediate illumination of lamp 68. Switch 44 includes contacts 174 and, upon momentary closure thereof, current flows from the power source through normally closed cam switches 166 and 168, through relay winding 170, and foot pedal switch 44 to energize the relay winding. Adjacent to winding 170 is a relay armature 176 secured to relay switches 178 and 180. When winding 170 is energized, the relay armature is drawn therein, thereby closing the relay switches. Since relay switch 178 is disposed in parallel with foot switch 44, switch 178 remains closed and current continues to fiow through circuit 160, the current passing now through switch 178 rather than contacts 174. Energization of circuit 160 permits power to be supplied to circuit 162.
The timing and counting circuit includes a pair of timer motor-counter circuits 182 and 184. Circuit 182 comprises a counter mechanism 186 which includes a counter solenoid winding 188 and a timing motor mechanism 190 which includes a motor 192 provided with a motor winding 194. Counter solenoid Winding 188 and motor winding 194 are connected in parallel. Timer motorcounter circuit 184 is constructed similarly to circuit 182 and comprises a counter solenoid winding 196, included within counter mechanism 198, connected in parallel with a winding 200 of a motor 202, included in timing motor mechanism 204. A cam 206 is rotatably secured to motor 192 while a cam 208 is rotatably secured to motor 202, each ca m being operatively secured to switches 166 and 168, respectively. Cam 206 is provided with a lesser pe ripheral length than that of cam 208, which lengths are related to the speed of their respective motors and correspond to the amount of beverage passing through their respective faucets.
Circuits 182 and 184 are secured in parallel to a selector switch 210. Switch 210 includes a pole 212 connected to circuit 184, a pole 214 connected to circuit 182, and a'comrnon pole 216 connected to circuit at relay switch 178. A movable connector 217 is secured to pole 216 for selective contact with poles 212 and 214. Consequently, only one of the circuits 182 and 184 may be energized at any one time. Switch 210 is also provided with'a pair of poles 218 and 220 selectively contactable to common pole 222 to which a movable connector 223, similar to conenctor 217, is secured. A series conection of indicator light 56, a resistor 224, and pole 218 is secured in parallel with a similar series conection of indicator lamp 58, a resistor 226, and pole 220, both series connections being connected at one side by lead 228 and at the other side by'leads 230, 232, 234, and 236 to the source of voltage. Two transformers 238 and 240 are provided with respective primary windings 242 and 244 which are connected in parallel with relay switch at one side and leads 232, 234, and 236 at the other side. Thus assuming that poles 214 and 216 and poles 218 and 222 are closed in switch 210, when circuit 160 is energized, circuit 182 begins to operate as indicated by illumination of light 56 and primary windings 242 and 244 are energized.
Upon operation of circuit 182, counter 186 immediately records this event on indicator 62 and motor 192 rotates earn 206. Because of the coaction between the periphery of cam 206 and switch 166, circuits 160 and 162 remain energized until cam 206 no longer contacts switch 166. At that point, switch 166 opens to open circuit 160 which de-energizes relay winding 170. Both relay switches 178 and 180 then open to open circuit 162 and to maintain circuit 160 in an opened condition. Thereafter, a return mechanism (not shown) associated with cam 206 causes it to return to its start position to reclose switch 166. Cam 208 is provided with a similar return mechanism so that, if circuit 184 is actuated, switch 168 will be brought to its normally closed position.
Valve solenoid operating circuit 164 includes secondary windings 246 and 248 of transformers 238 and 244. A rectifier bridge 250 is connected to the secondary windings to convert the alternating current emanating therefrom to direct current and is secured in series to a switch 252 for supply thereto of the direct current. A filter network 253, comprising a resistor 254 and a capacitor 256 each disposed in parallel circuit with the rectifier, smooths the direct current supplied by the rectifier bridge. Switch 252 is selectively connected to windings 120 of one or the other of faucet assemblies 12 and 14 by respective leads 34 and 36. In order to correlate the respective solenoid windings with their corresponding timer motor-counter circuits, switches 210 and 252 are secured together for simultaneous operation by selector switch operator 54. To this end, switch 252 is provided with poles 258 and 260 alternately contactable by a common pole 262 by a movable connector 263 and poles 264 and 266 alternately contactable by a common pole 268 by a movable connector 270. Poles 260- and 266 are secured to the solenoid winding of faucet assembly 12 while poles 258 and 264 are connected to the solenoid winding of faucet assembly 14. Thus switches 210 and 252 are interrelated by operator 54 in such a manner that a closing of switch 210 between poles 212 and 216 and poles 220 and 222 correspond to a closing in switch 252 of poles 258 and 262 and poles 264 and 268.
Assuming that it is desired to fiil a pitcher with a beverage, thereby employing faucet assembly 14, selector switch 54 is positioned so that the above mentioned pole contacts are made. Power switch 60 is closed and the dispensing apparatus is prepared for operation as indicated by the illumination of lamp 68. Since it is desired that a pitcher will be filled, light 58 will also be illuminated to show that faucet assembly 14 is ready for action. Actuating switch 44 is then momentarily depressed so that current flows through circuit 160. Because relay winding 170 is energized, the relay switches close thereby making it unnecessary to continue to depress the foot pedal. Current then flows through relay switch 180, the primary windings of the transformers, and leads 232, 234 and 236. At the same time current flows through relay switch 178, poles 216 and 212, through timer motorcounter circuit 184 to begin operation of motor 202 and rotation of cam 208 and to cause counter 198 to register the event, and through leads 234 and 236. Current also passes through poles 222 and 220 (via a lead 272), lamp 58 and leads 230, 232, 234 and 236. Because of the alternating current flowing through the primary transformer windings, a current is aroused in the secondary windings which is conducted to bridge 250 for rectification into direct current which is smoothed by network 253, across poles 262 and 258 and poles 268 and 264 and finally to solenoid winding 120 of faucet assembly 14 wherein valve head 100 is unseated from orifice 84 and gasket 86. The beer begins to flow and continues to flow as long as earn 208 remains in contact with switch 168. When the cam, however, sufficiently rotates so that it no longer contacts switch 168, the complete circuit opens and the valve member and head under the urging of spring 138 shuts off the fiow of the beer.
Although our invention has been described wherein switches 210 and 252 are joined for simultaneous operation by operator 54, it is obvious that the switches may be independently operated wherein switch 210 is connected to operator 54 and switch 252 is connected to an operator 274 (see FIG. 1). It follows, therefore, that assemblies 12 and 14 may be secured for both glass and pitcher use, and may be secured by conduits 26 and 28 to different beverage sources.
Regardless of the particular connection between switches 210 and 252, the invention provides, among others, for a faucet which is exceedingly easy to clean. It is only necessary to disengage the assemblies from conduits 26 and 28, remove plate 116, unscrew screw 144, slip yoke 142 from key slots 110, and slide valve member 96 out of bore 80. This permits a full access to the member, the bore, and passage 88. This and other advantages accrue from the simplicity of the circuit and of the assemblies.
