DISPENSING APPARATUS.

To all whom it may concem:

Be it known that I, Crmnnns L. BASTIAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dispensin Apparatus, of which the following is a specification.

The invention relates to dispensing apparatus and is primarily adapted for dispensing carbonated beverages such as root beer where the mixture is made the glass upon a customers order.

The object of the invention is, generally, to provide an apparatus or" simple construction and eflicient operation, which will main tain the syrup in a sanitary condition and at a suitable temperature, and which will also cool the carbonated water to a temperature suitable for dispensing and drinking.

A particular object of theinvention isto maintain a substantially constant gravity pressure on the syrup at the draft arm to insure at all times an even, regular and uniform flow whereby tie operator may, by given manipulation of the draft arm, a ways draw ofi' the same charge of syrup regardless of the level of the syrup in the supply tank.

Another important object is to provide a closed syrup jar for storing the syrupin the apparatus and having a valve which can be removed for filling the jar and which will be automatically opened when the jar is arranged in its proper position so that the jar can be refilled and replaced under sanitary conditions and without spilling the syrup.

Another important object is to maintain a constant charging supply oi syrup from the syrup jar and provide for drawing off therefrom on a given operation of the draft arm not more than a predetermined quantity of syrup which should be sutiicient as a charge for one glass of the beverage, whereby uniformity in the quantity or" the charge may constantly be maintained.

And a further object of the invention is to operate the charging means and dispense the charge of syrup by a simple and ordinary manipulation of the draft arm lever, and to arrange the parts so that this lever may be operated to discharge a stream of Specification of Letters Patent.

water into the glass without causing a discharge of syrup.

I have illustrated the invention in an apinvention.

Fig. 2 is a horizontal, sectional view on the line 2-2 of Fig. 1.

Fig. 3 is a detail sectional view showing a slightly different construction.

eferring to the drawings, 4: designates a cooling tank which may be inclosed in a barrel or keg 6 or some other display form. The cooling tank is spaced from the walls of the barrel and this space is filled with some suitable packing'material 6 to exclude heat. The carbonated water enters the tank from a suitable supply through the pipe 7 and passes through the cooler 8 and the pipe 9 to the draft arm 10. The cooling tank is partly filled with ice 11 and a removable, insulated cover 12 forms a closure for the cooling tank and the bar rel. A drain cook 13 is provided at the bottom of the tank and barrel.

The syrup jar 14 is removably supported on one or more brackets 15 within the tank. This syrup jar is smaller in diameter than the tank so that the supply of ice can be replenished without removing the jar. The syrup valve is secured. in the bottom of the jar at one end thereof and the jar may be provided with a well 16, Fig. 3, if'desired, in which case the valve will be located in the bottom of the well. This valve comprises a body 17 which has threaded engagement with an opening 17 in the bottom of the jar and is provided with a cen tral passage 18 and one or more lateral connecting passages'l9. A valve stem 20 extends entirely through the valve body and carries the valve disk 21 on its upper end within the syrup jar to seat against the upper end of the central passage 18 for closing the syrup outlet. A spring 22 is arranged on the other end of the stem between the valve body and a head 23 on the outer extremity of the stem. Beneath the syrup jar there is a charging tank 24 which is open at the top and is connected at the bottom by pipe 25 with the syrup passage of the draft arm. This draft arm can-be made in any form suitable for the purpose and I have not considered it necessary to illustrate the construction of the draft arm and need only say that it is preferably of a form which will discharge syrup, a large water stream and a fine water stream.

When the syru jar is in place in the tank the head 23 on t e valve stem engages the bottom of the charging tank 24 and the parts are dimensioned and proportioned so that in this position the valve will be unseated to permit syrup to flow through the passages 18 and 19 into the charging tank. The syrup jar 14 is closed except by the valve and thecharging tank is open at'the top so that when the valve is opened syrup will flow by gravity into the charging tank until the lateral passages 19 are submerged and, since the valve remains open constantly while the 4 syrup-jar is supported within the cooling tank 4, a" substantially constant level of syrup may be maintained in the charging tank 24, the supply in this charging tank being replenished automatically as a charge of syrup is drawn off through the draft arm.

The level of syrup in 'the charging tank may be observed at all times through the gage 27connected with the draft arm outside of the barrel. When the syrup jar removed from the cooling tank for refilling or for any other purpose the valve will close automatically and immediately after the stern head islifted from engagement with the bottom of the charging tank. The syrup jar may be refilled through the opening 17 after unscrewing and removing the valve, and after the syrup jar is refilled, the valve is screwed back into place in the opening 17 to form a complete closure for the jar sothat' y it can be handled and replaced without spilling or leaking.

To insure a constant uniformity in 'the quantity of the syrup charge I provide a measuring cup 28 in the charging tank 2% which is normally located below the level of the syrup therein. This measuring cup is provided in its bottom with a discharge pipe 29 which telescopes and slides in a. pipe 30 secured in'the bottom of the charging tank and communicating with the pipe 25. The cup has upwardly projecting arms 31 in which 'a transverse pin 32 is secured. and a link 33 is connected to said'pinyand to the outer end of a lever arm 34: which is secured on a rock shaft 35 mounted in the walls of the charging tank. A pinion 36 is rigidly mounted on this rock shaft 35 outside of the charging tank and is engaged with a toothed segment 37 on a lever 38 which is pivoted at 38 on the side of the charging the handle lever into the glass.

mediate section 41 The section 41 is pivotally connected at its ends to the lever 38 and to the section 41". The section fil is pivotally connected at its ends to the handle lever ,40 and to the section 41". The section 41" is arrangedto slide in a guide sleeve 42 which is secured in the walls of the barrelor keg and cooling tank. This sectional pivot-' ed connecting rod permits the

end sections

41 and 11 to swing withthe segment lever 38 and handle lever 10 while the intermediate section 42 slidesin a straight line.

The construction is such that normally the I measuring cup is submerged in the charging tank while the handle lever is in closed position. WVhen the handle lever is pulled forward, to the left in Fig. 1, the segment lever 38 is swung on its pivot tocause the segment by engagement with the pinion to rock shaft 35 and swingvthe arm 3 1 to lift the measure ing cup until its top clears the level of the syrup. At or about the time the syrup dis charge is thrown open by manipulation of the handle lever the measuring cup is lifted above the level of the syrup in the charging tank so that the charge or" Syrupflncluding that in the pipes as well as that in the cup itself, will'fiow freely and quickly through No more than this charge will flow even though the handle lever is held to open position of the syrup discharge for a longer period than is necessary to deliver the charge because the syrup must flow throughthe measuring cup from the charging chamber and while the handle lever is in position to hold the syrup discharge open the measuring cup will be above the level of the syrup in the charging. tank, When the handle leveris returned to neutral, closed position, as shown in Fig. 1, the segment is out of operating engagement with the pinion so that the handle lever may ing further movement of the pinion, the

measuring cup or other connections.

It is highly desirable that a syrup charge of the same quantity should be delivered not only from one apparatus but from other apparatuses dispensing the same beverage so that uniformity of the product which is desired by the manufacturer will always be maintained. The manufacturer who puts a popular beverage on the market generally prepares his syrup with the intention that a predetermined charge will always be used in a glass oi a certain-size and the popularity of the beverage and the success of the manufacturer is to a considerable extent due to the manner in whiclrthe beverage is dispensed, and the public is entitled to the same uniformity in beverages which are dispensedin this way as it expects in bottled beverages. My present invention provides a sure and certain means for dispensing at all times a uniform syrup charge of constant quantity and if a glass is used for which the charge is intended and the proper quantity of water is drawn the beverage should be disposed as uniformly as if it were bottled by the manufacturer.

The syrup is maintained in a sanitary condition and is dispensed in an even, steady flow to the glass. The invention provides for filling the syrup jar under sanitary conditions and for keeping the jar. closed until it is replaced in position in the cooling tank. The syrup valve is always open while the syrup jar is in proper position in the cooling tank and therefore the charging tank may be constantly filled with syrup to a predetermined level sufficient at all times to supply an even, regular flow through the draft arm. The syrup will not spurt into the glass but will flow in a steady, even stream and the measuring cup insures a uniformity of the syrup charge.

My invention is shown embodied in a simple form in an apparatus for dispensing root beer and similar beverages but I do not intend to limit myself to this particular embodiment or use and I reserve the right to make any changes in the form, construction and arrangement of parts as fairly fall within the scope of the following claims:
