14 Claims.

This invention relates to faucets of the kind wherein a viscous syrup is intermixed with carbonated water or the like to dispense a creamy drink.

Many syrups merely contain a natural or artificial liquid flavor dispersed in a saturated solution of sugar and water but other syrups, such as chocolate, contain solid matter. When a fine stream of carbonated water is discharged into a wholly liquid syrup in a faucet it is possible to break up the syrup and so mix the water therewith that a frothy or creamy drink is discharged from the faucet but when the syrup contains solid matter it is difficult to break up the syrup and mix the water therewith in a manner conducive to the production of a creamy drink. One of the objects of my invention is to effectively break up any of the various kinds of syrups and mix carbonated water or the like therewith to produce a frothy creamy drink.

Another object is to first partially break up a syrup and mix it with a quantity of carbonated water in a faucet to reduce the viscosity thereof and to subsequently so introduce a stream of carbonated water into the mixed water and syrup that a frothy creamy drink is dispensed from the faucet. 1

A further object is to provide a novel faucet wherein two or more streams of carbonated water or the like are discharged into a passage through which a syrup is flowing so as\to thoroughly intermix the syrup and water to thereby insure a thorough intermixture of the water and syrup in a manner conducive to the production of a creamy drink prior to discharge thereof from the faucet.

Still further objects are to produce a faucet wherein a stream of water is directed into a passage, through which a quantity of syrup is flowing, in a direction substantially opposite to the flow of the syrup; to regulate the discharge of water into the syrup to control the relative proportions of syrup and water intermixed in the faucet; to regulate the fineness of the stream of water to thereby' control the admixture of syrup and Water; to direct two or more streams of water into a passage through which a quantity of syrup is flowing in predetermined relation with each other to effect dispersion of the water in the syrup and thereby effectively mix the syrup and water; to flush out the passage, wherein the syrup and water are mixed, after each operation of the faucet to maintain a-sanitary condition in the passage and to prevent dripping from the discharge end of thefauCe a d to provide a novel faucet of simple and economical construction and efllcient and positive operation.

Selected embodiments of the invention are illustrated in the accompanying drawing wherein Fig. 1 is atransverse sectional View and in which certain parts are shown in elevation;

Fig. 2 is a longitudinal sectional view taken substantially on the line 2-2 on Fig. 1;

Fig. 3 is a view similar to Fig. 1 showing a modified form of the invention;

Fig. l is another view similar to Fig. 1 showing a further modified form of the invention;

Fig.5 is a horizontal sectional view taken sub.- stantially on the line 55 on Fig. 4; and

Fig. 6 is a view similar to Fig. 5 showing a further modified form of the invention.

The preferred form of faucet illustrated in the accompanying drawing comprises a substantially cylindrical body I having a boss 8 projecting radially therefrom substantially medially in the extent thereof. Another radially extending boss 9 providing a nozzle l projects from the body I medially in the extent thereof and at right angles to the boss 8. A flange I 0 is provided at the free end of the boss 8 and is adapted to be connected to a suitable fixture. A syrup passage l I and a water passage l2 extend through the boss 8 and syrup and water supply pipes are respectively connected to the outer ends of the passages and these connections are concealed by the flange Ill.

Recesses l3 and H are provided at opposite ends of the body I. A washer I is disposed at the bottom of the recess l3 and a tumbler I 6 seats thereagainst. The tumbler includes a diametrically extending rib l1 seated in a diametrically extending bifurcation in the connector H! which includes a neck l9 extended through an opening in the nut 2| secured to the adjacent end of the body 1 and holding the connector I 8 in position. A handle 22 is secured on the connector I9 by the nut 23. A bolt 24 extends throughthe nut 23 and the connector l9 and engages the rib I! to force the tumbler l6 into tight engagement with the Washer l5.

A passage 25 is provided in the tumbler i6 and terminates in ports disposed in the face of the tumbler engaging the washer i5. A passage 26 extends from the inner end of the passage II to a port in the washer l5. Another passage 21 extends from a port in the washer l5 and through body I to the upper end of the outlet passage 28 which extends through the nozzle I 0. The tumbler l6 may be rotated to register the ports therein with the ports at the ends of the passages 26'and 21 whereupon syrup floiws from the passage ll through the passage 26, passage 25 and passage 21 to the outlet passage 28.

A washer 29 is provided at the bottom-of the recess l4 and the face of a; tumbler 39 is engaged therewith. The tumbler 30 includes the diametrically extending rib 3| seated in 2. diametrically extending bifurcation in the connector 32. The connector 32'is retained in position by a nut 33 engaging the adjacent end of the body 1. A handle 34 is secured to the connector 32 in the same manner as that in which the handle 22 is secured to the connector l8. similar to the bolt 24, forces the tumbler 38 into tight engagement with the washer 29. A passage 36 extends from the inner end of the water "passage l2 through av medially located port in the washer 29 which communicates with acentrally located port 31 in the tumbler 30., Three ports 38, 39 and 40 are provided in the face of the 'tumbler 30 engaging the washer 29 and communication is established between these ports and the port 31 through a passage 4| in the tumbler 30. The ports 38, 39 and 48 are adapted to successively register with a port -in the washer 29 at the end of a. passage 42 which extends through the body 1 to a passage 43 in the body and which extends through the nozzle l8 parallel to but spaced from the passage 28. Communication between the outlet passage 28 and the water passage 43 is established in a manner to be described so that water flowing into the passage 43 may be discharged into the passage 28 to be-intermingled with syrup flowing through said passage 28 from the passage 21. Another passage 44 extends through the tumbler 30 from the port 31 toa port 45 inthe face of the tumbler engaging the washer 29. Theport 45 is adapted to register with a port in the washer 29 at one end of a passage 45 leading to the inner end of the outlet'passage 28.

The handles 34 and 22 are interconnected by a nut 46so that they may be operated simultaneously. A pin 41 extends from the body 1 above the boss 8 and another pin 48 extends from the body 1 in spaced relation with the-pin 41. The

handles 22 and 34 are enlarged to provide a boss 49 engageable with the pins 41 and 48. A ball handle 50 is provided' above the nut 46 to facilitate operation of the handles.

' When the boss 49 is engaged with the pin 41,

the tumblers I6 and 39 are so disposed that flow of syrup through the passage 25 is closed off and flow of water through port 31, passage 4| and ports 38, 39 and 40 and passage 44 and port 45 is closed off. However,'when the handle 59 is grasped and the boss 49 is moved from engagement with the pin 41 toward and into engagement with the pin 48, syrup and water flow into the passage 28. The port at the end of passage 45 is so located that immediately following disengagement of the boss 49 from the pin 41, the port 45 moves into registration therewith and water flows from passage 36 through port 31,

passage 44, port 45'through passage 45 into the outlet passage 28. At this time no syrup is being discharged'from the port 21 and the effect of thisdischarge of water is to flush out the outlet passage 28. After the port 45 moves from registration with the port at the end-of passage 45 andupon continued movement of the handle 58, thelport 38 moves'into registration'with the port at the end of passage 42 and at this time the ports at the end of the passage 25 will be slightly A bolt 35,

in registration with the ports at the ends of passages 26 and 21 so that a small quantity of syrup flows into the outlet passage 28. It will be noted that the port 38 is of restricted size and hence only a small quantity of water flows into the passages 42 and 43 and the outlet passage 28. As the handle 58 continues to move, the ports at the end of thepassage 25 move into further registration with the ports at the ends of passages 26 and 21 and hence the quantity of syrup flowing into the outlet passage 28 is tration with the port at the end of passage 42 which afiords unrestricted flow of water into the passage 28. The graduated size of the ports 38, 39 and 40 permits flow of water to the outlet passage 28 in direct proportion to the quantity of syrup flowing thereinto through the passage 21. When the handle 58 is grasped and the boss 49 is disengaged from the pin 48 and moved toward the pin 41, the registration of the ports at the end of the passage 25 with the ports at the ends of passages 26 and 21 is successively diminished and the successively restricted ports 39 and 38 successively register with the port at the end of passage 42 so that as the flow of syrup is reduced the flow of water is likewise reduced. Immediately prior to the engagement of the boss 49 with the pin 41, the port 45 registers with the port at the end of passage 45. At this time flow of syrup into the outlet passage 28 is closed off andconsequently only Water flows thereinto and this water serves to flush out the outlet passage to maintain this passage in a sweet and sanitary condition and to prevent drippage from the dis- I charge end thereof.

A flushing faucet of the above described kind is disclosed in my Patent No. 1,930,461, patented October 17, 1933, and is the preferred type of faucet with which my invention is to be used although it is to be understood that my invention might be used in connection with any faucet providing for the simultaneous discharge of syrup and water Without departing from the spirit and scope of the invention.

The invention herein particularly relates to the 4 manner in which water flowing into the passages 42 and 43 is introduced into the outlet passage 28 and the invention particularly resides in thoroughly intermixing syrup flowing from the passage 21 into the outlet passage 28 with Water introduced into this outlet passage. The invention particularly resides in thoroughly intermixing a heavy syrup and particularly one containing solid matter (chocolate syrup being an example) with carbonated water so as to produce a soda. It will be noted by referring to Figs. 1, 3 and 4 that a plug 5| is inserted into the outer end of the passage 43 to effectively close off this passage, the

length of this plug depending upon the location of the passages interconnecting the passages 43 and 28. g

In the form of the invention illustrated in Figs. 1 and 2 provisionis made for discharging a fine stream of carbonated water into the outlet passage 28 in a direction substantially opposite to the flow oi syrup through this outlet passage. To this endan inclined port 52 is provided which extends at anfangle to the bore of the passage 28 and the port 52 is inclined upwardly. A boss 53 is provided on the side wall of the nozzle and a needle valve 54 is arranged therein to control flow of water through the port 52. The needle valve 54 is mounted in an opening 55 extending through the boss 53 across the passage 43 to the port 40. The opening 55 is tapped at 55 to receive the screw-threaded periphery of the needle valve and this mounting permits adjustment of the j needle valve relative to the port 52 to control water fiow through said port. The stem of the needle valve extends through suitable packing 5! arranged in the enlarged portion 58 of the opening 55, and the packing is held in position by a nut 59 mounted in the outer end of the opening 55 and having a recess therein to receive the end of the needle valve so as to conceal it. The opening terminates in a pocket 8 liwhich communicates with the passage 43 and the port 52 and water flowing through the passage 43 enters the pocket it from whence it flows past the needle valve 54 through the port 52 into the outlet passage 28. This water is discharged in the form of a fine stream which impinges against syrup fiowing down through the outlet passage 28. This fine stream of water tends to break up the syrup and as the water mixes with the syrup the viscosity is reduced and this intermixed syrup and water continues to fiow down through the outlet passage 28. A restricted port 62 extends between the passage 43 and the outletpassage 28. This port is disposed below the port 52 and water flows from the passage 43 through the port 52 into the outlet passage 28 in the form of a fine stream. The syrup and water intermixed in the vicinity of the port 52 flows into alignment with the fine stream of water discharged from the port 52 and this fine stream of water further intermixes the water and syrup and produces a creamy drink which is discharged from the lower end of the outlet passage 28. I have found that by spacing the water ports in the manner in which the ports 52 and 62 are spaced I am enabled to more thoroughly intermix heavy syrups with water and particularly those containing solid matter and so as to produce a creamier drink than is possible when only one stream of water is mixed with the syrup,

In Fig. 3 a modified form of the invention is shown. Herein two ports 53 and 54 open into the outlet passage 28 and these ports are arranged in spaced relation one above the other. These ports respectively communicate with pockets 63 and 64' which communicate with the water passage 43 and in this instance flow of water through each of the ports is controlled by a needle valve substantially similar to the needle valve 54, the needle valve 55 controlling water fiow throughthe port 53 and the needle valve 65 controlling water fiow through the port 54. Neither the port 53 nor the port 54 is inclined upwardly but I have found that this arrangement produces a thorough intermixture of the syrup and water and as one fine stream of water is mixed with the syrup prior to the time a another fine stream of water is mixed therewith and a satisfactory creamy drink is discharged from the passage 28.

Not all syrups contain solid matter and even those syrups which contain solid'matter may be intermixed with water so as to produce a creamy drink provided the admixture of the water and syrup is thorough prior to discharge of the syrup and water from the nozzle. I have described how a creamy drink can be produced by discharging one stream of water into the syrup prior to the time another stream of water is discharged thereinto. However, I have found that by discharging streams of water so that one stream impinges on the other a thorough dispersion of the water results and that water so dispersed thoroughly intermixes with syrup flowing through the passage into which the water is discharged so that a creamy drink results.

In Figs. 4 and 5 I have illustrated one manner of discharging two streams of water into a passage so as to impinge one on the other whereby the water will be thoroughly intermixed with the syrup. In'this instance I provide two ports 61 and 68 which are disposed in the same horizontal plane but in diametrical opposition to each other.

The port 5! opens into a pocket 58 and communication between this pocket and the water passage 43 is established through a passage 10. The flow of water through the port 51 is regulated by a needle valve 1| substantially similar to the needle valve 54. The port 58 opens into a pocket 12 and communication between this pocket and the water passage 43 is established through a passage !3. A needle valve 14 similar to the needle valve 54 controls water fiow through the port 58. Preferably a drill is passed through the boss 9 to drill the ports 61 and 68 at the same time to insure alignment thereof. aligned one with the other, the fine streams of water discharged from these ports in opposition to each other impinge one on the other so that the water is violently dispersed in all directions and hence this water thoroughly intermixes with syrup fiowing through the passage 28 which produces a creamy drink.

In Fig. 6 a modified form of the invention illustrated in Fig. 5 is shown and herein two ports 15 and 15 are provided which are disposed in the same horizontal plane but which open into the passage 28 at right angles to each other. The port 15 leads to a pocket 11 and communication between the pocket 11 and the water passage 43 is established through the passage 18. A needle valve 19 controls the flow of water through the port 15. The port 16 leads to a pocket 50 and communication between the water passage 43 and the pocket is established through the passage 81. through the port 16. The needle valves 19 and 82 are both substantially similar to the needle valve 54. Fine streams of water flowing from the ports 15 and 16 impinge one on the other and the water is violently dispersed so as to be thoroughly intermingled with syrup flowing through the passage 28 and this insures the discharge of a frothy creamy drink from the outlet passage 28. It will be noted that the syrup is introduced into the outlet passage 28 adjacent the inner end thereof and that the intermixed syrup and water flow from the end of the passage 28 opposite that whereat the syrup is introduced into said passage and therefore the streams of water are introduced intothe passage intermediate the outlet end of the passage and the place whereat the syrup is introduced thereinto so that the intermixture of syrup and water occurs during the fiow of the syrup through the outlet passage and toward the outlet end thereof.

I have provided a faucet embodying a passage through which a syrup is caused to flow and I have shown different ways for introducing \streams of water into this passage to be thoroughly intermingled with syrup flowing therethrough.

Since the ports are A needle valve 82 controls the flow of water 'I'he streams of water may beintroduced into the passage one in advance of the other so that water and syrup may be first intermingled and thenthis thoroughly intermingled water and syrup may be churned by the introduction of the second fine stream of water which I have found produces a creamy drink even where a heavy syrup containing solid matter is caused to flow through the passage into which the streams of water are discharged. The production of a creamy drink may be enhanced by discharging one or both of the streams of water into the passage in a direction substantially opposite to the flow of syrup through the passage for I have found that this increases the intermixing of the syrup and water in such a way as to-produce the desired frothy and creamy drink. However, a thorough intermixture of syrup and water may be obtained by discharging two or more streams of water into the passage in such a way that the streams of water impinge one on the other for this disperses the water throughout the passage and insures intermixture thereof with the syrup.

In the faucet selected for showing and describing the invention, the liquids are intermixed in the upper portion of the outlet passage which becomes for this purpose a mixing chamber and from this chamber the intermixed liquids are discharged through the lower end of the passage, and while the passage as shown is tubular and continuous in form, it may obviously be differently shaped to provide the mixing chamber and discharge in adapting the invention for other faucets or for other purposes. I have also shown and described means for flushing the outlet passage to 'maintain it in a'sanitary condition and to prevent drippage but, as herein indicated, the invention is not restricted to this combination and may be embodied in faucets of other kinds. Changes in the form and construction and arrangement of parts and modifications thereof may be made to enable my invention to be used in different kinds of faucets and for diiferent purposes for which it is or may be adapted, and I reserve the right to make all such changes and. modifications as fall within the scope of the following claims. 7 f
