DRAFT ARM FOR DISIENSING BEVERAGES.

Application filed May 14,.1923. Serial No. 838,690.

To all whom it may concern: Be it known that I,ALrHoNso L. KoENIo,

a citizen of theUnit'ed States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Draft Arm for Dispensing ieverages, anddeclare. the following to be a full, clear, andexact description of the same, such as will enable others skilled in t the art to which it pertains to make and use the same, reference being had to the accom- 'i'anying drawings, which form a part of this specification. i I i lVly invention relates particularly to so Y called fountains from which either a beverage from a single source or a mixture of liquids from two different sources is dispensed, and has for itsjobject to simplify and improve theconstruction of the same.

Where a mixture of two liquids is made mduring the dispensing process, one of the liquids is usually a liquid under pressure and the other a syrup intended to be supplied in comparatively small accurately measured quantities; an example being the heveragedispensed in the form of root beer and] consisting of a mixture-of soda Water and a syrup in definite proportions. Difii culty has heretofore been experienced inaccurately measuring and. delivering the syrup, because air must be expelled from the measuring chamber while the chamber is being filled and must be introduced into the chamber to replace tlre' syrup while the la ter is being discharged; and, so far as I know, no apparatus has heretofore been devised which permits accurate measurement and delivery of the syrup by mechanism controlled by the same handle which controls the discharge of liquid from a single source or a mixture thereofand syrup from a second source.

I overcome this difficulty by placing between a syrup-measuring chamber and a conduit leading from the syrup container, a valve device actuated by the dispensing handle and so constructed that air from the measuring chamber is passed to and temporarily trapped. in the syrup supply conduit as syrup enters the measuring chamber and that the measuring chamber is shut off from the said syrup supply conduit and opened to atmosphere when the syrup is flowing out of the. measuring chamber, whereby the measuring chamber will be being shown,

filled with air at atmospheric pressure exactly equal in volume to the syrup discharged; the syrup supply conduit having aSSOCItLlGd therewith a standpipe open atthe top and so placed that during each cycle,

comprising the filling and the emptying of the measuring chamber, a measuring-chamher full of air, at atmospheric pressure, is allowed to escape through the standpipe.

It is desirable, not only to be able to discharge a single liuid or a mixture of two liquidsby manipu ating a single handle, but also, in either case, to be able to control the volume and pressure of the stream that is being discharged, and to vary the discharge between alarge Stream of low velocity and a fine needle-like stream of high velocity,

or a combination of the two; and one of the objects of the present invention is to produce such a draft arm.

- The various features of novelty whereby my invention is characterized will hereinafter he pointed out with particularity in theclaims; but for. a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawings, wherein:

Figure 1 is a vertical section through one of my improved draft arms, the container for a syrup, and a barrel or other receptacle to which the draft arm is applied and in which the container for the syrup is located', only a fragment of said barrel receptacle being shown; Fig. 2 is a section taken approximately on line 2.2 of Fig. 1, only the lower half of the devicebeing shown, and one of the valve devices being in a different position from the same device in Fig. 1; Figs. 3 and 4 are views similar to Fig. 1, only those parts outside of the barrel and the valves being shown in two positions differing from those in Fig. 1; Fig. 5 is an end or front view of the draft arm, looking at the right hand end in Fig. I; Fig. 6 is a section taken approximately on the irregular line 6-6 of Fig. 4, the parts occupving somewhat different positions than in Fig. 4: Fig. 7 is a view on an enlarged scale of a fragment of the lowermost valve mechanism; the parts occupying the same positions as in Fig. 6; Fig. 8 is a side view of the stem for supporting the valve mechanism in the lower end of the nozzle; Fig. 9 is a section taken approximately on line 9-9 of Fig. l, the lower end of the nozzle being broken away; Fig. 10 is a view similar to Fig. 9, the controlling handle being in the same position as in Fig. 6; Fig. 11 is a section taken approximately on line l111 of Fig. 5; and Fig. 12 is a section taken approximately on line 1212 of Fig. 5, only a fragment of the device being shown.

Referring to the drawings, 1 represents a barrel or other receptacle within which is placed a closed syrup container 2. On the outside of the barrel is the valve mechanism and controlling handle of the draft arm assembled in and upon achambered body 3 having at the inner end a flange 4 resting against the outer side of the receptacle 1 and fastened thereto by screws 5 or otherwise. The member 1 has a large opening 6 through the same, this opening registering with the inner end of the member 3. A conduit 7 of comparatively large diameter lies horizontally within the barrel, projects through the opening 6 in the latter, and is screw-threaded at its outer end into the member 3. A tube 8, much smaller in diameter than the conduit 7, extends downwardly from the bottom of the syrup container, preferably at the middle thereof, through the upper wall of the conduit 7 and downwardly into the latter; the members 7 and 8 being secured together in any suitable way. At the extreme inner end of theconduit 7 is located an elbow 9, the internal diameter of which is greater than the internal diameter of the tube 8 and considerably less than the internal diameter of the conduit 7; the arm of the elbow adjoining the conduit being horizontal and the other arm being vertical. From the upper end of the vertical arm of the elbow a small pipe 10- extends upwardly and opens into' the side of the syrup container at a point above the highlevel of the liquid in the latter. The outer end of the conduit registers with the inner end of a valve chamber 11 in the member 3. In this chamber is located a plug valve 12 in the form of a deep cup open at the inner end so as, in effect, to form a rotatable continuation of the conduit 7. The plug valve and the chamber in which it lies are slightly tapered so as to insure a tight fit between the same. In the member 3, directly below the valve chamber 11, is a measuring chamber 13 having in the top wall thereof an elongated slot 14 extending parallel with the longitudinal axis of the plug valve. This slot preferably increases gradually in width from the inner to the outer end. In the bottom wall of the plug valve is a slot 15 similar to but wider than the slot 14. When the slots 14 and 15 register with each other, syrup may drop down from within the valve with a tubular cross piece 17 WhlCl forms a passage way extending transversely through the valve. WVhen the controlling handle is in its neutral or upright position, as shown in Figs. 1 and 9, one end of the tubular member 17 lies at one side of but not far flom the slot 14 in the top of the measuring chamber. The other end of this tube lies at some distance from a port 18 extending through the top wall of the member 3. The parts are so proportioned that when the actuating handle is swung in one direction from its neutral position far enough to bring the slot or port 15 fully out of registration with the slot or port 14, the ends of the tube 17 register respectively with the slot or ort 14 and with the port 18, as shown in ig. 10. In other words, after communication between the source of supply for the syrup and the measuring chamber has been completely cut off, the measuring chamber is placed in communication with the outside air, so that air may enter the measuring chamber as the syrup flows out of the same.

When the measuring chamber has been emptied, as will hereinafter be described, it will be full of air at atmospheric pressure. Therefore, when the controlling handle is returned to its neutral position, bringing the slots or ports 14 and 1'. into registration with each other, syrup may flow b y gravity from the interior of the plug valve into the measuring chamber, the air in this chamber finding an outlet in the upward direction into the interior of the plug valve. Thus it will be seen that whenever a charge of syrup is drawn from a supply conduit into the measuring chamber, it will be replaced by an equal volume of air at atmospheric pressure.

The parts heretofore described form a complete system for quickly transferring syrup from the'container 2 into the supply conduit 7 and thence into the l'neasuring chamber and insuring the filling of such chamber, regardless of the height of the liquid level in the container, and without the necessity of employing any pressure other I than atmospheric pressure therein. Assuming that the apparatus is empty, as shown in Fig. 1: then upon filling the container 2 with syrup to a level somewhat below the point at which the upper end of the pipe 10 is connected to the container, the syrup will flow down through the tube 8 into the conduit 7, travel toward the right, as viewed in Fig. 1, until it begins to flow down into the measuring chamber. After the measuring chamber has been filled, the syrup will rise in the conduit and in the elbow 9 until the extreme lower end of the tube 8 is submerged and a level in the plane of the highest point in the openin at the right hand end of the elbow is reacled. Up to this time the air which was displaced by the syrup has passed in the conduit and plug valve.

freely through the elbow and pipe 10 into the top of the syrup container. Now, however, the air remaining in the conduit and the interior of the plug valve is trapped above the syrup in these parts and offers resistance to a further rise of the li uid level owever, there is still a static head tending to force the syrup up through the elbow 9 into the pipe 10; the result being that a condition of equilibrium will be established in which the syrup in the pipe 10 has the same surface level as that in the container. The port leading downwardly into the measurin chamber may now be 0 ened and closet without producing any e ect on the syrup,

but, after the measuring chamber has been emptied and the controlling handle returned to the neutral position, themea suringchamber'will be quickly refilled and the air that was contained in the empty measuring cha n her will pass up through the syrup until it mingles with the air previously pocketed in the conduit and plug valve above the syrup. The outlet tube 8 from the syrup container is smaller in diameter than the elbow 9.

- The surface tension of the syrup tends to retard the starting of a downward flow through said outlet tube, and therefore a large part of the syrup needed to fill the measuring chamber flows out of the elbow.

Consequently, since the pipe 10 is much smaller in diameter than the elbow, the liquid level in the pipe 10 will drop far below that in the syrup container. The amount of air in the conduit has been increased by a volume exactly equal, at at mospheric pressure, to the volume of the syrup that has entered the measuring chamher, and therefore this additional amount of air must esc a )e from the conduit before the original eon ition of equilibrium is obtained. As soon as the level in the pipe 10 drops below the liquid level in the syrup container, the differential pressure is sufiicient to start a down flow of syrup through the tube 8. The extra air in the conduit takes the easiest way out, and therefore passes laterally into the elbow 9 and thence up through the pipe 10 into the syrup contaiuer. l have found that in actual practice the air rushes up into the pipe 10 with such force that it does not pass through the pipe 10. Therefore, at the'end of a cycle,

the measured quantity of air that is drawn from the atmosphere into the measuring chamber to replace an equal volume of discharged syrup, will be found in the syrup container, where it serves to replace an equal volume of syrup that has been discharged from the container to refill the measuring chamber. The cycle of operations, just described, is repeated with respect to each charge of syrup dispensed.

The soda water is delivered to the draft arm through a pipe 20, a valve-controlled extension of which extends horizontally through the measuring chamber. In the arrangement shown, the pipe 20 terminates in'a hollow plug or nipple 21 screwed into one end of a shell 22 secured within the inner end of the measuring chamber; the

the tube 24. The lower portion of the front or outer wall of the measuring chamber is thickened to form a block 25. The discharge nozzle 26 for the device is screwed on a short tubular part 27 integral with the body nember 3 and arranged in part underneath the block 25. The tube 2i is of compara'tively large diameter, the inner end being closed by a plug 28 having a comparatively smallopening through the same. The

outer end of this tube, where it joins the front wall of the measuring chamber, is reduced in diameter and registers with a small chamber 29 in the block 25. Lying within the tube 24 is a valve 30 controlling communication between the source of sup ply of the soda water and the chamber 29., Connected to the valve 30 is a stem 31 extending through the chamber 29 and through a hole in the block 25 to the exterior of the latter; the part 32 of the valve stem in the chamber 29 being enlarged to give it increased strength. In order to prevent leakage around the valve stem 32, the block 25 is provided with a suitable stuffing box 33 surrounding the outer end of the valve stem. A spring 34 within the tube 24: tends constantly to hold the valve 30 against its seat. A passage opens down through the bottom of the block 25 from the chamber 29 at the veirtical axis of the discharge of the soda water. Into the "open end of the member 21 being covered i bottom of the block 25, coaxial with the passage 35, is cut an annular groove 36, a portion of-which is in open communication with the measuring chamber, so that when i the measuring chamber is full of syrup,

the latteriextends into and fills the annular groove. The floor of the measuring chamber preferably inclines downwardly as the annular groove is approached, so as to permit the measuring chamber completely to empty itself when the syrup is permitted to flow out of the annular groove.

The open bottom of the annular groove is adapted to be closed by an upwardly-seating valve 37 fixed upon a tubular stem 38 fitted. slidahly into the discharge passage 35.. The valve. is normally held closed by means of a spring 39 arranged between the under side thereof and the, bottom 40 of a cag'ei4-l screwed into the nozzle-su porting member 27. 1f the valves 30 ant 37 are opened, assuming the measuring chamber to be filled with syrup, syrup will flow out of the measuring chamber through the groove 36 andgpastthe valve 37, while soda water will flow;.down through the tubular valve stem; 38, both liquids entering the discharge nozzle. The syrup is not under pressure,

simply flowing out of the measuring chain her under the action of gravity, as heretofore explained. Therefore, in order to assist the discharge of the syrup, I form perforations 42 in the wall of the tubular valve stem 38, just above the valve 37, so that, when all the valves are open, the soda waterwill be discharged in the radial direction from the tubular valve stem across the ,top of the valve 37, producing an injectorand 47 separated from each other by the,

section 45. The section 46 forms a higher ram .than the section 47 and is longer than the latter. The cam 44 is engaged by a cam roll 49ycarried by the upper end of an actuating lever 50, whose lower end 51 engages the outerend of the valve stem 32; the actuating lever being pivotally supported in a .jaw 52 forming part of an upward extension 53 of the block 25.

When the controlling handle 16 stands upright, the cam roll is engaged with the low flat section of the cam. When the handle is moved toward the left, as viewed in Figs. 5 and 6, to the posit-ion indicated by dotted circle 16, the cam section 47 rides past the cam roll,

as shown in Fig. 1, liquid flowin forcing the upper end of the actuating lever outwardly and causing the valve stem 32 to be pressed inwardly so as to open the valve-30 and permit soda water to flow down through the tubular valve stem 38.

The lower end of the tubular valve stem 38 is enlarged, as indicated at 55, to form an elongated hollow cylindrical head closed at the bottom. The enlargement or head is provided with several rows of perforations 56 through the cylindrical wall. The upper end of the head lies a considerable distance below the bottom of the valve 37, and that portion of the stem located between the bottom of the valve 37 and the upwardlyfacing surface of the head 55 is preferably made square, as best shown at 57 in Fig. 8. The head 55 fits slidably into a sleeve 58 in the form of an inverted cylindrical cup having in the middle of the bottom thereof a. square hole to fit the squared portion 57 of the tubular valve stem; the top of the cup being of a thickness less than the shortest distance between the valve 37 and the head 55, so as to permit the sleeve to slide up and down on the valve stem for a limited distance. The sleeve 58 is provided with several rows of perforations 59 adapted to register fully with the perforations 56 when far as the valve 37 will permit, as best shown in Fig. 7. The internal diameter of the lower portion of the sleeve 58 is made greater than the external diameter of the head 55 for a distance/such that when the sleeve is moved up as far as it will go on the stem, as shown in Fig. 7, the lowermost row of the holes in the head will lie opposite and in communication with a surrounding annular space 60 between the outer wall of the head and the inner wall of the sleeve. The parts are furthermore preferably so proportioned that the portion of enlarged internal diameter of the sleeve approaches the lowermost row of perforations 59 to within a distance equal to about one half the diameter of the perforations 56; thus making it possible to have the perforations 56 and 59 partially in registration with each other and at the same time have the lowermost row of perforations 56 registering partially with the surrounding annular passa e or chamber 60. Into the lower end of t e sleeve 58 is screwed a nozzle 61 having a very small discharge passage 62. Therefore, when the ports 56 and 59 are Wholly in registration with each other, down through the tubular valve stem and into the enlarged head thereon, can escape only through the perforations 56 and 59 into the surrounding chamber in the nozzle 26; when amuse the perforations 56 and 559 are wholly out Of registration wi h each other, as shown in Figs. '6 and 7, such liquid can escape only through the lowermost row of perforations 56 into the lower end of the sleeve, and

thence through the small nozzle 161'; and

when the two series of perforations are only partly 1n registration with each other and the lowcrmostrowof the perforat1ons'56 registers partly with the annularchamber There is a light spring 63 arran ed within the sleeve 58 and its nozzlefil and engagin with the under side of the head ofth'e tu' bular valve stem; thus causingthe sleeve to he yieldingly held in its lowerrnost posi-- tion relatively to the tubular valve stem, namely, theposition in which the two sets of perforatious,'56 and'59,"register. When it is desired to change the nature of the stream which is being discharged by the device, the attendant need only, press down on a small finger piece in the form of a lever 6i extending through the wall of the nozzle 26 and having at its inner end a fork which engages with the under side of the small nozzle/61 without obstructing the'discharge outlet therefrom; downward pressure on the finger piece forcin the perforated sleeve up'and permitting t is liquid to be discharged either in a fine needle-like stream of high-velocity or as a combination of such a stream with a slowly-moving gushing stream. 1

When it is desired to dispense a mixture of soda water and syrup, thecontrolling handle is shifted from the neutral, uprightpositiontoward the right, as viewed in Figs. 5 and 6, causing the valve 30 and also the valve 37 to be opened. The controlling means for the valve 37 is best shown .in Figs. 5 and 6. Resting loosely on .tp'p of the valve 37 along the outer margin portion thereof, are two vertical pinsflfl lidablv mounted in the blockw25. 'rh eluppea when the contmlling'handle is moved out of its neutral position into a 7 sition for dispensing a mixture of ii ui s. In dispensing soda water alone, t e valve 30is not opened as far as it is when a mixture is being made and dispensed, because the cam section 46 which controls the main valve in g the soda water pipe during thelatter process, is higher than the cam 47. Therefore, in dispensing soda water, the pressure may be said to be controlled within the tubular member 24., whereas, when a mixture is being dispensed, the full pressure of the source may be transferred into are tubular valve.

stem and the control ofthe pressure be effected after the tubular valve stem has been reached. When the controlling handle reachesthe position indicated in dotted lines at 16" in Fig, 6, theport 15 in the lu valve will have been carried complete y beyond the port of slot 14.- in the top of the measuring chamber and, as the movement of the handle is continued toward the full line pog sition shown in Fig.6, the measuring chamber will be connected to the surrounding atmosphere as heretofore explained. The cams are so proportioned and, so located that the valves 30 and 37 will not be opened until communication between the measuring chamher and the source of supply for the syrup has been interrupted; but, as soon as the port or slot 15 in the plug valve passes out i of registration with the port or slot 14. the valves 30 and 37 begin to 0 n, syru flowing from the measuring c amber irectly into the main nozzle chamber past the valve 37; fine streams of soda water being discharged laterally across the topof the valve 37, through the holes. 42 in the tubular valve stem, as heretofore explained. The two sets of perforations 56' and 59 in the enlarged head of the tubular vaIveQstemjand in the surrounding sleeve are in registration with each other so that soda water flows down through the tubular valve stem and out through these perforations to meet the de soendmg syrup, so that the syrup and soda water are mixed in the large nozzle and discharged in the form of a. shing stream of large volume and low ve ocitv. As the downward movement of the valve 37 continues, the sleeve 58 with its small nozzle 61 travels down with it. until the lower end of. the sleeve strikes the stationary part 40, whereupon the sleeve comes to rest and the valve 37 continues its downward movement until it closes the gap between the same and the upper end of'the sleeve: the final position of the parts being that shown in Figs. 6 and 7, namely, the position which c'auses'all of the sodawaterthat is being dis- 7 pensed, to be discharged either through the small ports 42 above the valve 37, or through the small nozzle 6.1. In other words, except for the soda water that is discharged through the small ports 42, it may be caused to be discharged laterally through the large number of registering holes 56 and 59, to be discharged in part laterally through these holes registering only partially with each other and partly through the small nozzle 61, or

i to be discharged wholiy in the form of a fine streamof high Velocity through the small nozzle :61. Consequently a large variety of conditions, not only asv to the size and character of the stream or streams, but also as to the pressure thereof, may be obtained. It will be noted that the finger piece 64 is not needed for the purpose of dispensing a mixture of liquids, but forms a slmple means for controlling the nature of the flow/of soda water in order to secure the same efi'ects with the valve 37 closed as when such valve is opened to mix syrup with the soda water.

Fig. 1 represents the parts in their neutral positions, while Fig. 3 shows the positions of the parts when plain soda water is being dispensed in the ordinary way;

and Fi 2 illustrates the positions of the parts w en the finger piece 64 is actuated to cause the soda water to be delivered in a I single line stream. Fig. 4 shows the posi- 7 in a single fine stream through the small nozzle 61.

In order yieldingly to; hold the hollow plug valve against its seat and automatically take up wear therein, I makeuse of a small post 80 having a reduced inner end 81 fitting into a hole in the outer end of the plug valve; the plug valve and the post being co-axial and the fit between the two being such that while there is no looseness, the post and the valve may rotate relatively to each other and move lengthwise relatively to each other. Between a flange or collar 82 near the inner end of the post, and a cover 83 fastened to the body member 3 so as to conceal the cams, is a spring 84 which constantly presses the post and. therefore. the plug valve inwardly. There is less triction between the inner end of the post and the valve than there is between the spring and the collar or flange or between the spring and the cover 83, and therefore the post normally remains stationary when the plug valve is rotated. The cover may conveniently take the form of a substantial rectan ular box open at the inner end and at the ttom, and of such a size that it may rest upon and form a harmonious upward continuation of the block 25. The projection or extension 53 ontop of the block 25, as best shown in Fig. 12, is made shorter than the width of the block so that it will engage at its ends with the inner surfaces of the side walls of the cover. The cover may conveniently be fastened in place by means of a tapered pin 85 driven through the side walls of the cover and through the extension or projection 53 lengthwise of the latter. By making the pin tapered it may readily be removed to detach the cover.

It is desirable that some means be provided for permitting the size of individual charges of syrup to be varied. This can conveniently be accomplished by making the effective size ofthe measuring chamber adjustable. In the arrangement shown, the stationary shell 22 in the measuring chambar has a portion of enlarged internal diameter surrounding the tube 24. Slidable on the tube and fitting into the annular recess or chamber thus formed between the shell 22 and the tube 24 is a collar 90. When the collar is pushed into this annular recess or chamber as'far as it will go, as indicated in Fig. 1, the capacity of the measuring chamber is at its maximum. If the collar be moved toward the right along the supporting tube, it will cause the effective capacity of the measuring chamber to be decreased by exactly the amount of the free space leftbehind the collar within the surrounding shell. In the arrangement shown, the member 90 is provided with superficial grooves 91 into any one of which may extend the pointed end of a set screw 92 screwed into the bottonrwall of the measuring chamber. When it is desired to change the ca pacity of the measuring chamber, the set screw is removed, any small instrument is inserted through the hole for the set screw,

and the .collar moved along the supporting sleeve in the proper direction thereby; aml the set screw is then put back to lock the sliding collar in its adjusted position.

While I have illustrated and described with particularity only a single preferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described; but intend to cover all forms and arrangements which come within the terms employed in the definitions of my invent-ion constituting the appended claims.
