Heretofore, beverages such as punches," Peruvian bark wine and the like were poured in a glass or a cup by preselected dosage units but in an approximate manner by the bartender or attendant and heated by steam as usually drawn from the steam cock of a coffeebrewing machine.

Thisp'rocedure has given rise to bles.

In the first place, the dosage of the beverage is entrusted only to the personal appreciation which is rather rough, of the person pouring the beverage; in the second place, the temperature at which the beverage is heated is a function of the time of stay in it of the steam cock of the coffee machine, a time which, also in this case, is evaluated in a rough manner only by an operator; consequently the beverage can be either too cold or too hot, that which could also have a negative bearing on its taste. It may also occur that the steam as not negligible trou- FIG is a cross-sectional view taken along the line invention in a first embodiment thereof is structurally composed by a central boiler, I, an upper metering unit, 2, and a lower dispensing unit. 3.

The boiler l is embedded in an annular heating block 4, made of a material which is a good heat-conductor and is electrically heated through a heating circuit (not shown), which can be of any appropriate kind for maindrawn, instead of being fairly dry, as it should be, is

comparatively moist so that the beverage becomes undesirably diluted.

The principal object of the invention is to do away with the defects as enumerated above by obtaining a device adapted to dispense or to deliver an exactly preselected dosage unit'of heated beverage at a temperature which has also been preselected and constant for all of the dosage units.

Another object of the invention is to provide such a device which is of simple, cheap and speedy construction and whose upkeep can be made also by untrained operators. 1

With these objects in view, according to the invention, it has been envisaged to provide a beverage dispensing device which is characterized by comprising a reservoir communicating through a first port with a metering chamber which, in turn, communicates through a second port with a heating chamber, the latter being equipped with a third, dispensing port, a first, a second and a third valve means controlling said first, second and third port and being mechanical connected to be axially transferredbetween a first and a second end positions wherein, respectively, the first and the third port are open while the second port is closed, and vice versa.

The transfer of said valve means can be controlled, for example, either by an electromagnet or by a motorreducing gear unit, which are operatively connected thereto by a linkage.

In order that the features of the inventionmay be better understood, an exemplary description will be given hereinafter of two preferred embodiments thereof, with reference to the accompanying drawings, wherein:

FIG. 1 is a cross-sectional vertical view showing the device in its operative position.

' FIG. 2 is a vertical cross-sectional view showing the device in its inoperative position.

FIG. 3 is a cross-sectional view taken along the line IIIIII- of FIG. 2.

FIG. 4 is a cross-sectional view taken along the line lV-IV of FIG. 2.

taining the block 4 at a preselected temperature. Said boiler comprises two cylinders 5 and 6, having different diameters, arranged the one in the interior of the other, so as to define an annular jacket or heating chamber 7 therebetween. The outer cylinder 5 is stably secured to the block 4, whereas the inner cylinder 6 can be-axially translated, as will become apparent hereinafter.

The metering unit 2 is formed by a valve comprising a valve body 8 which is divided into two tubular pieces 16 and 17: the piece 16, having the larger diameter, is affixed to the block 4 by screws such as 9, whereas the piece l7, having the lesser diameter, is freely slipped into the piece 16 and abuts with its annular flange 18 an annular ledge 19 of the piece 16 itself.

Within the body 8 there are slidably and axially mounted a first and second valve members 10, ll borne by a single valve-stem 12. The valve member 10 v is formed as an entity in the stem 12 near the lower end thereof and has the shape of an annular projection having a tapered outline 13 adapted to cooperate with a valve seat 14 of the piece 16, equipped with a sealing ring 15. The valve member 11 has the form of a comparatively resiliently yieldable shutter affixed by a screw 20 to the other end of the stem 12. The shutter.

11 is adapted to close in a sealtight manner a port 21 of the piece 17: the port 21 serves to establish a communication between the interior ofa bottle 22, screwed means 10, keeps the stem 12, and consequently the valve members 10, 11, in the position shown in FIG. 2. As clearly shown in the drawings, the stem 12 is hollow in its interior and has its lower end freely slipped into a frustoconical tip 27 which is extended axially of the top wall 28 of thecylinder 6. The cylinder 6 is open at its bottom end and, in correspondence with this end'has an edge 29 which is flared towards the outside and is adapted to cooperate with an annular sealing gasket 30 housed in a seating of a tubular piece 31, the latter being affixed with screws 32 to the bottom end of the block 4. Thus the cylinder 6, in addition to defining with its body the chamber of annular jacket 7, fulfils, with its flared edge 29, also the function of a third valve.

The dispensing unit 3 is operatively connected to the cylinder 6 and comprises a tubular-piece 33, which is terminated by a funnel 34 and has an outer annular chamber 35 which encompasses the piece 31 and is in communication with the funnel 34 through circumferentially formed openings 36 (FIG. formed through the piece 33.

The cylinder 6 along with the dispensing unit 3 con- I nected thereto via the piece 33, as clearly shown in the drawings, is borne by a lever 37 which controls also its axial sliding motion. The lever 37 is fulcrumed at either end at 38 to a framing (not shownH'or supporting the device and, at the opposite end it is connected, through a spring 39, to the armature 40 of an electromagnet symbolically indicated at 41. The lever 37 is fulcrumed at an intermediate point 42, to the cylinder 6.

The operation of the device as described above is as follows. On starting an operative cycle the device is in the position shown in FIG. 2. With the device in such a position, the beverage, following the path indicated by the arrows, emerges from the bottle 22 until com- "pletely filling the chamber 24 and the four passageways tion circuitry of conventional make (not shown); thus the armature 40 is drawn into the position shown in FIG. 1 so as to rotate in the clockwise direction the lever 37, which, through the point 42, lifts the cylinder 6 with its edge 29 in a sealtightengagement against the annular gasket 30. As clearly shown in the drawings, the lifting of the cylinder 6 causes, through the tip 27, the sliding upwards of the valve stem 12 so as to bring the valve member-or shutter 11 to close in a sealtight manner the port 21 and to disengage the valve member 10 from its valve seat. Consequently the beverage unit dosage passes into the annular chamber or jacket 7 of the boiler 1 and the beverage is prevented from being poured from the bottle 22 by the shutter 11. The beverage unit dosage in the chamber 7 is heated by the block 4 to a preselected temperature within a preselected time. 7

At this stage the hot beverage unit dosage is ready to be delivered and its delivery takes place by causing the electromagnet 41 to be de-energized to restore the device to the position shown in FIG. 2. With the device in this position the sealing edge 29 of the cylinder 6 is disengaged from the gasket so as to establish a com munication between the chamber 7 of the boiler l and the chamber of the dispensing unit 3. The beverage unit dosage thus passes from the chamber 7 into the chamber 35 and therefrom, through the ports 36, into the funnel 34 which provides to dispense it, along an axial flux path, into a glass or a cup (not shown).

It is apparent that, simultaneously with the dispensing of a dosage of'preheated beverage, a fresh unit dosage passes from the bottle 22 into the passageways 23 and into the chamber 24.

The boiler l and the units 2 and 3 can be made, with advantage, of a plastics material, whereas the heating block 4 is made of a metallic material.

Having now reference to FIGS. 6 to 9 of the drawings, another possible practical embodiment of the invention will be describedhereinafter.

This embodiment comprises, similarly to the former, a central boiler 101, a top metering unit 102, and a bottom dispensing unit 103.

The boiler 101 is embedded in an annular heating block 104, made of a material which has a good heat conductance and electrically heated through a heating circuit (not shown), which can be of any kind adapted to keep the block 104 at a preselected temperature. The boiler comprises two cylinders 105 and 106, having different diameters and arranged the one within the other so as to define anannular jacket or chamber therebetween, 107, for heating purposes. The outer cylinder 105 is permanently secured to the block 104, whereas the inner'cylinder 106 can be translated axially, as will become apparent hereinafter. The translation of the cylinder 106 is guided by a plurality of ribs The metering unit 102 can be formed by a valve comprising a valve body 108 in two tubular pieces 116, 117 screwed onto one another. The body 108 is removably mounted on the block 104 by a bayonet coupling 109.

Within the body 108 there is axially slidab'le. a valve member 112 equipped at its ends with two annular sealing gaskets 110 and 111; these gaskets are'of theliplike type and aremade of an appropriate resiliently yielding material. The gasket 110 is adapted toclose in a sealtight way achamber 121. The chamber'12l serves to establish a communication between the interior of a reservoir, for example abottle (not shown) screwed tween the metering chamber 124 and a chamber 143,-

through which the liquid is fed into the heating chamber 107. A gasket 144 mounted on a header at the top of the cylinder 106 is adapted to close in a sealtight mannerthe top portion of the chamber 107: a plurality' of passageways 146 put in communication the chamber 143 with'the outside atmosphere. A compression spring 126 urges the valve element 112 towards the position of FIG. 8 and the translative'motionof the element 112 is guided by radial webs 147.

The cylinder l06 is openat the bottom end, in correspondence with which it has an annular gasket 130 shaped in a liplike fashion: this gasket 130 is adapted to close in a sealtight manner the chamber 107 by cooperating with the end portion of the inner wall of the cylinder l05.-Thus the cylinder 106, in addition to defining the space of the chamber 107, also fulfils'a valve function as will become apparent hereinafter.

The dispensing unit 103 comprises a. tubular piece 133 which is terminated by a funnel 134;'the piece 133 is secured to the cylinder 106 by a plurality of uprights 148 having crenellations 149 which snappingly engage circumferential ribs 150 on the inner wall of the cylinder 106; in addition, for a correct match between the crenellations 149 and the ribs 150, the uprights 148 have a shoulder 151 which abuts the edge of the cylinder 106 The cylinder 106 and the dispensing unit 103 connected thereto is borne by means of a lever 137 which.

also controls the axial displacement thereof. The lever 137 is fulcrumed at either end at 138 to the block 104, at an intermediate point 142 to the cylinder 106 and is filled with the beverage, as will be seen hereinafter,

and the gaskets 130 and 144 simultaneously engage their respective seatings and isolate the heating chamber 107.

' By so doing, the formation is avoided of possible sugary incrustations on the walls of .the chamber 107, which could occur were the chamber 107 to stay a long time in contact with the outside atmosphere.

As the motor-reducing gear 156 is set on, the cam follower 152 goes along the ascending ramp comprised in the sector 157; consequently, the lever 137 is lifted and, in turn, causes the cylinder 106 to slide upwards and the valve member 112 is urged towards the position of-FlG. 7. In this position, the dosage unit of beverage falls. from the chamber 124, passing throughthe chamber 145, into the heating chamber 107. ln the chamber 107, the beverage dosage remains for the time which is necessary to heat it, this time being preselected by the length of the constant-radius portion of the cam, as confined by thesector 158.

As the follower 152 begins to go along the first descending portion P, of the sector 159, the lever 137 and therewith the cylinder 106 and the valve 102, are depressed towards the position shown in FIG. 8. At this stage, due to the bias of the spring 126, the displacement ofthe valve 102 takes place at first to the position of FIG. 850 as to cut the communication between the chambers 124 and 107 and to open the passageway 121 for theintroduction of a fresh dosage unit into the chamber.l24. Thereafter the delivery of the heated beverage takes place through the funnel 134.'lt should be noticed that the cam portions P P and P comprised in the sector 159 originate a progressive and controlled delivery of the beverage by gradually opening the annular passageway for communication between the chamber 107 and the funnel 134.

The arrangement of sealing gaskets as suggested in this embodiment is such as to ensure that, as the valve members are in their end positions, thefirst and the third port are open only after the sealtight closure of the second port, and vice versa. In this way undesirable liquid seepings between the reservoir, the metering chamber and the heating chamber are prevented during the operation of the device.

These gaskets, during the translational motion of the valve members carry out a continuous and effective scraping of a portion of the inner walls of the chambers, thus preventing the formation of detrimental incrustations of material thereon.

The arrangement of these sealing gaskets and the operative sequence of the valve members are such, moreover, that, in theinoperative position of the device, the reservoir, the metering chamber and the heating chambers are all closed in a sealtight manner.

It is apparent from the drawings that-the subject device can easily be dismembered for upkeep, for exampie for washing, even by untrained persons, that which is a great advantage for the user. The device, in addition, easy to wash also automaticallyby feeding it during one or more cycles with an appropriate washing liquor.

Although two embodiments of the invention have been illustrated and described, those skilled in the art will realize that modifications and changes can be introduced therein without thereby departing from the scope of the invention. For example a battery or set of distributors could be provided, embedded in a single heating block and containing, each, a different kind of beverage.
