INVENTOR. NAPS/Ml! .4. M'. L'M/N United States Patent 3,144,967 DEPENSENG DEVL'CE Marshall A. Met/lain, 3161 hi. Gladys 8h,

San Gabriel, Ualif. Filed Jan. 27, 19631, Eier. No. 85,247 7 t'jlaims. (El. 22it lddfi) This invention relates to devices for selectively dispens ing any one of several liquids or combinations thereof, and more particularly to hand held dispensers which are used at bars for such purpose.

An object of this invention is to provide an improved dispenser for liquids.

Another object of this invention is to provide a semiportable hand carried dispenser for selectively supplying mix or liquids for drinking purposes.

A still further object of this invention is to provide a liquid dispenser capable of selectively dispensing any one of three liquids alone or any one of three other liquids in combination with one of the first mentioned liquids.

Still another object of this invention is to provide a unique, compact, mechanical operated hand dispenser which can accommodate and selectively dispense more different fluids than prior hand dispensers.

A still further object of this invention is to provide an inexpensive, compact hand dispenser for fluids.

Other and further objects of this invention will become apparent in the detailed description below in conjunction with the attached drawings wherein:

FIGURE 1 is a plan view of a preferred embodiment of the invention;

FIGURE 2 is a cross section of the dispenser shown in FIGURE 1 taken along line 2-2 in FIGURE 1;

FIGURE 2A is a fragmentary View taken along line 2A-2A in FIGURE 2;

FIGURE 3 is a cross sectional view taken along line 33 in FIGURE 2;

FIGURE 4 is a cross sectional View taken along line 4- in FIGURE 2;

FIGURE 5 is an enlarged plan view of the head of the dispenser with the cover removed, and;

FIGURE 6 is a partially broken away view of the right side of the dispenser shown in FIGURES 1 through 5.

Embodiments of the present invention are most widely used at commercial bars to enable the bar tender to mix and otherwise dispense more rapidly drinks to the customers. Therefore, the present invention shall be described in that environment. In addition the particular embodiment of the invention shown is presently being sold to a great extent to dispense soda water, Coca-Cola, 7-Up, Ginger Ale, plain water, and quinine water. Therefore, in the detailed description below, I will refer to the different portions of the dispenser with reference to such fluids in order to facilitate understanding the invention. Naturally the invention is not limited to the use of such fluids only.

Six flexible liquid conducting tubes lltl, enclosed in a sheath 11, extend from the rear of handle 12 of the dispenser to a remote point (normally below or adjacent the bar) at which is located the supply of syrups, soda water, quinine water, and plain Water. These liquids are supplied under pressure by conventional means which do not comprise part of the invention and therefore are not disclosed or described. In addition, as will become apparent in the description below the valves in the dispenser head are essentially two position, that is on-off valves. Therefore there is usually provided for each tube It) a metering valve which controls the flow of liquid when the associated valve in the dispenser is open. However such metering valves are located at the supply end of the tubes 1d and are also conventional, and therefore are not shown.

3,144,957 Patented Aug. 18, i964 Before describing in detail the mechanism by which the disclosed embodiment of the invention accomplishes the purpose of the invention, I will describe the function of the dispenser illustrated from a broad aspect. At the forward end of the handle 12 is located a head generally indicated by the arrow 13. This head comprises a body or housing 14 carrying the various components of the device, Which body is partially enclosed by a cover 15. Extending through the top of the cover 15 is a generally rectangular soda button lid which when depressed allows the soda water to be dispensed through the subject devlce.

Located in front of the soda button 16 are three syrup buttons 1'7, 18, and 19 which, when depressed cause to be dispensed Coca-Cola, Ginger Ale, and 7-Up respectively. As will become apparent in the description below, each of these buttons 17 to 19 is operatively associated with mechanism so that as the particular button is depressed, not only is a valve controlling the flow of syrup opened, but the valve controlling the flow of soda water is also opened. By this arrangement the particular syrup is mixed with the soda water as the two liquids are discharged from the dispenser.

Located on the left side of the head 15 and extending through a suitable hole in left side plate 21 is aleft side button 22. In the embodiment disclosed the button 22 preferably controls the bow and discharge of ordinary waterfrom the dispensing device while button 24- located on the right side of the head is used for controlling the flow and discharge of a liquid such as quinine water.

it can be seen how easily the subject dispensing device can be operated because of the compact physical size of the dispenser and the location of the various control buttons, which compactness and button location arise from and are made possible by, among other things, the unique construction of the invention illustrated herein.

Referring now to FIGURES 2 to 5 the particular construction and mode of operation will be described. Since the soda Water is discharged either by itself or with any of the three syrups control apparatus for this liquid will be described first.

Located within the dispenser is a sodavalve indicated generally by arrow 26. (See ETGURES 2 and 4 in particular.) This soda valve includes, affixed to the rear side of the body 14, a rigid tube 27 to which is attached the particular flexible tube 10 which is connected to the supply of soda water. From the tube 27 the soda water flows around the valve 26, through a longitudinal passage 28 in the body 14 and thence "through a vertical outlet passage 29.

Formed within the tube 27 is an annular seat 30 through which extends an actuator rod 31 carrying an (bring gasket 32 which selectively seals againstthe seat 3d. As can be seen the pressure of the soda water urges the valve 526 closed. However, it has been found desirable to provide a light spring which functions to keep the valve 26 closed when there is no pressure on the upstream side of the valve. To thisend there is provided a light spring 33 located around the rod 31 and acting against the seat 39 and a snap ring 34 located in a suitable recess in the rod 31.

An enlarged serrated guide 35 on the rear end of the rod 31 stabilizes the rod at that end while a spider 36, press fitted into the passage 2% guides the rod 31 at the rods forward end. in FIGURE 2A furtherdetails of the configuration of the spider 36 may be seen. To facilitate the manufacture of the subject dispenser, the rod 31 terminates a short distance within the passage 28 where it abuts the concave rearend of a rod 39.

The rod is connected to the rear edge of an oval ring so, which has a stub shaft attached to its forward side on which an actuator shaft ll is threaded. At the rear amass? m is end of the shaft 41 is an Q-ring which seals against the wall of bore 42 and also tends to support the combination of the ring 4%, rod 39 and shaft 4-1 in the forward and rearward movement of the combination.

In order to move the shaft 41 rearwardly and thus open the soda valve 26, a soda actuator lever 46 is pivoted at 47 and normally abuts the forward end of the shaft 41. As seen from the side, i.e. the aspect of FIGURE 2, the lever 46 is bent rather similarly to a L. and extends upwardly in front of body 14 and then rearwardly over the top of the body 14 to a position below the soda button 16. Accordingly by depressing the button in the lever 46 is rotated clockwise (as seen in FIGURE 2) moving the shaft 41, ring 4t and rods 39 and 31 to the right opening the soda valve 26.

Turning my attention now to the syrup valves, located within the bore forming the passage 29 is a member having a plug 50 at its upper end filling the bore, with a reduced portion 51 depending concentric to the vertical outlet passage 29 to a point which is flush with the bottom of the body 14. As will be described in more detail below, the reduced portion 51 has three passages within it through which is discharged any one of three syrups according to the desire of the operator.

The three syrup valves are substantially identical in construction and mode of operation. Therefore only the center valve actuated by the button lb is shown completely and will be described in detail. The other syrup valves will be described with reference to the center syrup valve.

Referring again to FIGURE 2 in particular, one of the syrup conducting tubes is connected to a passage 53 which opens at its forward end to a reduced passage 54 having a vertical outlet passage 55 extending therefrom down through the above mentioned reduced portion 51. Therefore the syrup may flow from tube 10 through passage 53 around a syrup valve indicated generally by the arrow 57 and through passages 54 and 55.

Forming part of syrup valve 57 is a specially shaped bolt 59 carring an 'O-ring gasket 58 which seals against the seat formed at the junction of passage 53 and 54 when the bolt is moved forward. The shank of the bolt 59 extends through the reduced passage 54 and is of smaller diameter than the last mentioned passage in order that syrup passing by the valve 57 can flow through to the outlet passage 55.

The shank of the bolt 59 extends forwardly into an enlarged bore 60 in which is disposed a coupling 61 threaded on the forward end of the bolt. Also located in the bore 60 is a spring 62 which performs the dual function of biasing the bolt 59 forward to normally close the valve 57, and holding against the rear end of the bore 6t? and O-ring seal 64. At the front end of the coupling 61 is an adjustment screw 63 which extends through the properly oriented hole 65 in the soda valve actuator lever 46.

In order to move the bolt 59 rearwardly and thus open the syrup valve 57, a syrup actuator lever as is also pivoted at 47 and extends generally contiguously with the soda actuator lever 46 to a point immediately below the center button 18. (See also FIGURE 5.) With such arrangement, as the operator pushes downwardly on the button 18 the syrup actuator lever 66 pushes on the adjustment screw 60 thus opening the syrup valve 67, and at the same time the actuator lever rotates clockwise (as seen in FIGURE 2) the soda valve actuator lever 46 thus opening the soda valve 26 as described previously. At this time syrup would be discharged from the outlet passage 55 while soda water would discharge through outlet passage 29.

It should be noted that by adjusting the screw 63 it is possible to commence the flow of soda water just before commencing the flow of syrup or just after commencing the flow of syrup, or at the same time as the flow of syrup is commenced. Similarly this same adjustment would cause the soda valve 26 to close just before, or

at the same time as, or just after the syrup valve 57 is closed. t is preferred that the soda valve 26 opened just before and closed just after the particular syrup valve is opened or closed. Thereby the soda tends to flush off the end of the portion 51 through which the syrup outlet passages open.

Turning now to the description of the other two syrup valves, as mentioned above they are substantially identical in structure and operation as the center syrup valve 5'7 just described. Each of those valves comprises a bolt 68, the shank of which can be seen in FIGURE 3 extending through a reduced bore 69 with sufiicient clearance to allow syrup supplied from an associated tube 10 to pass as in the case of the center reduced bore 54. Each of these bolts 68 also has the adjustment feature and spring biasing feature of the center syrup valve.

In order to actuate the left and right syrup valve, each such valve is provided with an actuator lever 70, which is substantially the same shape as and Works in substantially the same manner as the actuator lever 66. The actuator levers 7d are also pivoted at 47. The actuator levers 7th do differ from the lever 66 in that they extend further back across the upper portion of the soda lever 46 than does the lever 66 (see FIGURE 5); however this is only so that they extend to a position directly below the buttons 17 and 19 respectively. By that arrangement, either of the syrup valves may be opened by depressing the associated button 17 or 19.

Since the bores 69 are spaced laterally from the center of the outlet passage 2?; transverse bores 71 are provided to allow the syrup to flow to, and thence through, outlet passages 72 in the reduced portion 51. Plugs 73 close the passages 71.

The portion of the illustrated device so far is very similar both in function and in structure to my earlier dispenser which handled only three syrups and soda water. I found that it is very beneficial that the dispensing device also handle ordinary water and a liquid such as quinine water or a flavored liquid such as orange juice therefore by a unique design, I have been able to increase the capacity of my dispenser to six liquids without increasing the size of the dispenser and without prohibitive costs.

Referring now to FIGURES 4 and 6, right side valve indicated generally by the arrow 74 will be described in detail. Immediately inward of the right side button 24 is located a longitudinal bore '75 which is curved at its forward end 76 and opens to a cavity 77 in which the button 24 is located. Adjacent the rear end of the body 14, the bore 75 is counter-bored at 78 to form a seat at the junction of the bore and counter-bore. The counterbore 7'8 is threaded and receives a collar 79 to which is attached a nipple til which in turn has secured thereto the proper one of the flexible tubes 19.

Forming an important portion of the valve 74 is a mushroom shaped member d2 which is very similar to a bolt having no threads on its shank, or stem, which extends through the bore 75. This shank is smaller than the bore '75 in order to allow the flow of quinine water or flavored drink through the bore when the valve is open. Therefore, in addition to an O-ring gasket 84 carried by the member 8?. abutting the head thereof for sealing at the above mentioned seat, there is provided an O-ring 8 encircling the nember near the front end thereof for sealing and guiding purposes. Upon inspection of FIG- URE 4, it can be seen that the pressure of the liquid on the upstream side of the valve 7 i urges the valve closed. However, as in the case of the previously described valves, a light spring is used to bias close the valve 74 when tberc isnt any such upstream pressure.

Located within the curved section '76 of the passage 75 are a plurality steel balls 86 which are instrumental in opening the valve 7 i. These balls as are only slightly smaller than the diameter of the section 76. In addition, the curved section 7a, the member 32, the cavity 77, and the button 24 are sized and related so that when the memarcane? ber 32 is in its forward position (and the valve "id is therefore closed) the button is at its outer position with the unnumbered annular flange thereon engaging, or immediately adjacent, the side plate 23.

Therefore, with the above arrangement, when the operator presses the button 234%, the balls as, cooperating with the curved section 76 convert this lateral motion into longitudinal motion, moving the member d2 rearwardly opening the valve 74 against the biasing force of the sprin 8S and the pressure of liquid upstream of the valve '74. At this point the pressure on the upstream liquid forces the liquid through the nipple and collar 8% and 79 respectively, to the passage '75 and thence through a dl agonal passage d8 which opens to the outlet passage 29 near the lower end thereof. (See FIGURE 6 in particu lar.)

The associated passages down stream of the left side salve indicated generally by the arrow 9% are slightly different than the right side valve '74 just described. However, the remainder of the left side valve is substantially the same. More particularly it has provided a longitudinal bore or passage 93, which receives a mushroom shaped member 92 therein carrying an -ring gasket 9d abutting its head, which G-ring seals at the seat formed between the passage 93 and a counter-bore 95 at the rear end of the passage 93. In the same manner, as the right side valve '74, the left side valve 9% is nor sally biased closed by a light spring )7 acting against the head of the member $2.

150, as in the case of the right side valve '74, the passage 93 is curved outwardly at its forward end 99 and opens to cavity lltrtl in which the left side button 22 is located. Therefore, by means of balls till, disposed in the curved section 99, lateral motion of the button 22 by the operators thumb can move longitudinally the member 92 against the spring 9'"? and the pressure of the water thus opening the valve 99.

With the valve 94 open the water flows past the Cl-ring gasket 94 into the passage 93 and turns a right angle to flow through a transverse passage 102 into the previously described soda dispensing passages 28 and The water is directed into the soda passages 23 and 29 because the pressure is much higher than the pressure to which are subjected the quinine water and/ or the various syrups. (The latter liquids are supplied at, for example, psi.) And it has been found that by directing the water as described, it may be discharged at a very high rate without excess splashin it can be seen from the above description that the present device overcomes the disadvantages of a dispenser which can only accommodate three flavoring syrups and soda water. If the dispensing device cannot accommodate water in addition and also quinine water or another flavored liquid, a second and/ or a third dispensing nozzle must be provided for that purpose, thus complicating and making more time consuming the task or" the bar tender. It can also be seen that because of the unique construction of the device, the left and right side valve control buttons 22 and 24-, as well as, the syrup and soda valve control buttons can be quickly and easily used by the operator.

Although only one embodiment of the invention is shown and described in detail, it will be apparent to those skilled in the art that such is by way of illustration only and that numerous changes and modifications may be made thereto without departing from the spirit of the present invention. Therefore, it is my intention that this invention be limited solely by the scope of the appended claims.
