DISPENSING APPARATUS FOR A PLURALITY F LIQUIDS TO MAKE A RAINBOW CQCKTAIL OR THE LIKE I The present invention relates to an apparatus adapted to pour a rainbow or pousse-cafe" cocktail. This drink is composed of several liquors of different specific gravities, poured in succession intoa' glass, heaviest first, whereby the concoction is stratfield, adjacent liquors being different in color.
An object of this invention is to provide a novel and improved apparatus of the character mentioned, which includes a supply of individual liquors from which measured amounts are drawn off and dispensed in succession, so that a number of these cocktails can be served before the reservoirs need be replenished.
A further object thereof is to providea novel and improved apparatus of the nature described, which will work automatically, that is, upon merely pushing a button, the apparatus will operate, pour measured amounts of the respective liquors in succession, and then stop by itself in condition for the next push of the button for the repetition of the cycle of operation.
Another object thereof is to provide for changing the quantity of any liquid dispensed or to omit the dispensing of any of them during a cycle of operation.
A further object thereof is to provide for the proper spreading of the flow into the glass without s'plash and to assure no merging of liquid flowing into the .glass with the immediate previous layer.
A further object of this inventionis to provide a novel and improved dispensing apparatus having the mentioned attributes and which is simple in construction, reasonable in cost to manufacture, easy to manipulate and efficient in carrying out the purposes for which it is designed.
Other objects and advantages will become apparent disclosure proceeds.
For one practice of this invention, a rotatable turret on a vertical shaft, is positioned over a table which carries below it a motor-driven indexing means as' for instance a Geneva movement. The turret has a plurality of equi-angularly spaced spaced stations, at all but one of which is provided a releasably mounted structure serving as a cap for an inverted bottle holdng a supply of one of the liquors, and also as a measuring means and valve means; the operating member of the valve means extending below the turret to be met with a cam on the table near a discharge-receiving funnel which leads to a flow spreading means mounted on the underside of the table and adapted to sit into the mouth of a glass stood on a resilient shelf extending from a table leg. The Geneva movement shifts the turret in one direction, from station to station with sufficient dwell at each station to accomplish proper operation. In the normal rest position of the apparatus, the blank station is directly over the funnel. On the table are a normally open push button for starting, and a normally closed micro-switch controlled by turret movement for stopping the operation at the end of a cycle which requires one revolution of the turret.

This top plan view does show the switches included in the circuit, the valve-operating 'cam, the discharge-receiving funnel which leads to the flow spreader and the support for the glass.
FIG. 7 is a top plan view of the flow spreader, drawn to the scale of FIG. 4. t I
FIG. 8 is a bottom view of the bottle-receiving, valve and measuring structure. a
In the drawing, the dispensing apparatus shown designated generally by the numeral 15, comprises: a table or frame 14, above which is a turret 16 on a shaft 17 which is driven by an indexing device of the Geneva type 18, operated by an electric motor 19, which may require a speed-reduction device, not
shown; all driving mechanism being mounted below tabletop. The turret 16 is divided into eight equia-ngularly spaced sections, herein called stations, at all but one of which, the turret carries a releasably mounted structure denoted generally by the numeral 20, which serves as a cap for a bottle 21 held thereby in inverted position, as well as a measuring means and a valve means, which will be described in detail.
When the apparatus 15 is in normal rest condition, the blank station S is symmetrically over a discharge-receiving funnel 22 which leads to a flow'spreaderindicated generally by the numeral 23, whose tubular neck 24 is releasably mounted in the socket 25 in the undersurface of the table top, which may be by a bayonet lock type joint afforded by the fixed pin 26 and the segmental spiral channel 27. This socket 25 is communicative with the funnel 22 by virtue of the hole 28. The flow spreader 23 extends downwardly below the table top, and sets partly into a glass 29, which is stood on a resilient shelf 30 extending as a cantilever from a table leg 31. On the table are a normally open push button starting switch 32, a normally closed micro'switch 33, which is made to assume open condition by the arm 34 extending from the shaft 17, when the apparatus is in normal rest condition, which is the same condition it is in at the completion of a cycle of operation. Also on the table is a fixed cam denoted generally by the numeral 35, which is first reached by a station before arriving at discharge position over the funnel 22. The turret 16 revolves counterclockwise.
Each structure 20 comprises a body member which is here shown to be a rectangular block 36 having a laterally extending pin 37 which fits into a bore 38 in the turret body; the block fitting into a notch 39 in the turrets periphery, flush with the turrets upper surface, and extending below the turret. A knobbed set screw 39 engages thelocating pin 37 in an annular groove 40, therefor provided. This block may be of cast aluminum, having a downward central bore stopping short of bottom, but partitioned part way down with an annular seat 41, to define a lower chamber 42, and slightly counterbored from the top, to provide a seat 43 for the mouth rim of the bottle 21, whose neck tightly but releasably fits into the counterbore; the bottle being of plastic material having some resiliency, so the block fits the bottle neck as a cap thereon. The numeral 44 denotes a valve stem which passes spaced through the central hole 41' of the partitioning seat 41, and is of slightly reduced diameter, spacedthrough the hole 45 which is the outlet from the measuring chamber 42. The valve stem 44 extends upwardly into the bore: 38, where its end is reduced and carries secured thereto the rubber washers shown at 46 which normally hold the hole in the seat 41 closed, due to action of the stressed coil springs 47 which bias the stem downwardly. Said valve stem also extends downward out of the block body 36, where at bottom tip end, it has a head 48,
which is positioned to be intercepted by the cam 35, upon reduced lower end of said stem, in the space between said piece 50 and the block. The numeral 52 denotes a washer on the lower reduced end of the stem 44, and within the chamber 42 and normally across the discharge opening 45, to keep said chamber dust-proof. Said chamber which is for measuring the quantity of discharge, is vented by capillary hole 53 opening in the top surface of the block 36, where it has a counterbore 53. The bore 38 is vented by a capillary hole 54, which is communicative with a deep dent 55 in the wall of said bore, and opens in the top surface of said block, where it has a counterbore 54.
Heretofore, the flow of the discharge was directed directly into the glass, but was soon changed to be directed against the inside surface of the glass at one region. This has proven unsatisfactory. The former created splash, and the latter did not prevent mixing of successively poured liquids. I have remedied this by providing the flow-spreading or guide means 23, which distributes the discharge all around the inner wall of the glass, so the flow into the glass is sort of tubular. The tubular neck 24 is associated with a plug 56 which sets into the glass 29, to make an annular space 57 with the inside surface of the glass, which space may be deemed a thin ring of air space. The upper surface of the plug is either conical, or convex as shown. The apex of said plug has a conical teat 58 extending into the neck portion 24. The upper part of said plug extends into a receptaclelike member 59, having a peripheral upright wall and a bottom wall which is integral with the plug and is provided with the slots 60 therethrough, to make said receptacle communicative with the glass. The discharge from the apparatus, of course enters the tubular neck, which is provided with holes 61, to make it communicative with said container 59, which sets as a cover fitting onto the rim of the glass.
Referring to the circuit diagram of FIG. 3, the motor 19 is in circuit for connection to power mains by a usual connecting cord terminating in a connection plug 62, but said circuit has the starting switch 32 interposed therein. The stopping switch 33, is connected in parallel with said switch. At normal rest condition of the apparatus 15, the station S which is blank, is symmetrically over the funnel 22, the starting switch 32 is an open condition, and the arm 34 holds the stopping switch 33 in open condition.
To set up the apparatus 15, to be ready for operation, all the 1 structures 20 are removed from the turret 16, by first loosening the set screws 39, and then setting each of them on the supply bottles 21 as closure caps, whereupon the apparatus is reassembled so that the unit first to the left of station S,
holds the liquor supply of highest specific gravity, and theothers are mounted on the turret in counterclockwise order in succession, lower in specific gravity, so the unit immediately to the right of the blank station S, holds the liquor supply which is of the least specific gravity.
To make a rainbow cocktail, the glass 29 is set onto the resilient shelf 30, and guided to set against the fingers 64, so as to position the plug 56 into the glass, and the container member 59, atop the glasss rim. Of course, the glass is pushed down to flex the shelf, in order to accomplish this. Then the starting switch 32 is held closed a very short while to actuate the motor 19. As soon as the turret 16 moves, the arm 34 will move away from the operating member of the switch 33, whereupon such switch will assume closed condition before the starting switch 32 is allowed to open. The Geneva 18, movement will successively turn the turret, so each station carrying a laden unit will come to discharge position over the funnel 22, and dwell sufficiently for the measured contents filling the chamber 42 will be discharged. The speed of turret is of course suitable to allow the cam 35 to act on the valve stem 44 of the structure 20 approaching it, before reaching discharge position over the funnel 22.
The condition of the structure 20, before it reaches the cam, is shown in FIG. 4. The measuring chamber 42 is empty. The hole 41 which is its intake port is closed by the washer 46. The discharge port 45 is free from the washer 51 whose function is to close it. The bore 38, is of course filled with liquor from the supply bottle 21. As soon as the cam intercepts the head 48, and said head rides on the upper ca'm surface 35', the stem 44 of the valve is pushed upwards, whereupon the washer 51 closes the discharge port 45, and the washer 46 having moved upwards, the intake port 41 is opened, so liquor rushes in to fill the measuring chamber 42. Whenthe stem head 48 leaves he cam, the action of the springs 4Q will push the valve stem 44 downwards. At this time the said headis directly above the funnel 22, whereupon it is evident that the port 41 is closed, and the discharge port 45 is open, so the contents of the measuring chamber discharges into the funnel 22 and then downward into the neck 24, whence it'spreads onto the surface of the teat 58 and then further spreads out while it is flowing downward on the upper surface of the plug 56. The finely spread liquor is now guided through the air space in practically thin ring form onto the inner surface of the glass 29. This is repeated as each station comes to discharge position. When the blank station S, at the end of one revolution of the turret 16, is once again over the funnel as shown in FIG. 2, the arm 34 will open the switch 33, whereupon the motor 19 will stop, which is the completion of one cycle. The apparatus is now ready to repeat its performance for as long as the liquor supply lasts.
When the glass 29 is of a capacity of one ounce, which is a practical size, the combined capacities of the measuring chambers of all the unit structures 20, shall of course either equal or shall not exceed one ounce. Their individual capacities may differ. In the apparatus 15 shown, there is provision for seven liquors. If a lesser number is to constitute the concoction, then one or some of the units 20 are removed from the turret. Units 20 having measuring chambers of different capacity, may be interchanged in position on he turret, but their supply bottles shall replace one another, to maintain the specific gravity relationship of successive units.
To assure the correct positioning of the turret l6on the shaft 17, it is keyed thereto by a pin 65 through the shaft which fits into a groove 66 along a diameter so that when so set, the arm 34 holds the microswitch stopping switch 33, in open condition.
This invention is capable of numerous forms and various applications without departing from the essential features herein set forth. It is therefore intended and desired that the embodiment herein shall be deemed merely illustrative of the teachings of this invention.
