Figure 28 isa plan view, partially in section, of the parts as shown in Figure 27;
,c Figure 29 is a 'sectional view on the line 29-29 of Figure 26, and
- Figure is a sectional view on the line 30-30 of Figure 27. Referring more particularly to the'dfrawings, in which like reference numerals refer to the same parts throughout the several views, 1 designates a transparent display receiver `preferably of glass supported on a base 2, the latter being suitably mounted upon lthe top3 of a cabinet which also includes side walls 4 and a bottom 5. Mounted at thel bottom of the cabinet is areservoir 6. for containing the beverage supply whichl isk pumped from the reservoir through a pipe' and flexible conducting tube 8 to a discharge pipe 9 extending upwa'rdly'at the center -.of
t-he displayvreceiver and from which the beverage is. discharged-into the receiver'with a fountain effect. The reservoir `'is suitably iced or refrigerated, and the beverage may be permitted to'discharge into the display refceiver in other.. ways than that'spcciicallyshown. l. Y
The dischargeV pipe 9, which is preferably of glass toV aord transparency; is clamped inplace by the resilient or rubber ring'9a,
Y which is compressed tightly against the glass by means of the nut 10, see Figure 10.v Thus the glass tube is held securely in position in such a way as to prevent its readily breaking. The beverage falling to the bottom of the display receiver enters anfoutlet 10, see Fig-V ure 10, passingthence through flexible conf` ductor 11 to the top of reservior 6,1in this fashion maintaining a continuous circulationV of beverage between the reservoir 6 and the display receiver 1. As the beverage flows away from the bottom of the display receiver back to the reservoir, a certain amount of Yfrom the top 0f reservoir 6 to an outlet in the display receiver, such outlet being preferably in the form of agoose-neclr 14, the open end of whichis normally above the level of liquid in the display-receiver. This permits passage of cold air from the top of reservoir 6, orthe space above` the level of liquid in thereservoir, to the display receiver, such air beingvdrawn bacl into the reservoir 6 through `the y,outlety 10 as theV beverage is re-` turned. The` effectofthis is to maintain a relativelyv cold body ofV air in the display -receiver and' prevent sucking in warm air from outside the display receiver, thus per-- mitting a continuous circulation of beverage for purpose of display' without materially reducing its temperature, and requiring a minimum amount of refrigerant to maintain the beverage at the desired temperature.
The Abeverage is forced from the reservoir 6 to the'dis'play receiver by. a suitable pump mounted on a shaft 21 that- Vis driven byan i electric motor 22, said parts being mounted and supported on the shelf 23 within the cab? inet; yIt is desirable toafford a yieldable and separable connection between the motor shaft and the pump shaft, in order toy permit ready separation of the parts and efficient operation ofthe pump without the necessity of close alinementbetween themotor shaft and pump shaft, and this is accomplished by the constructionthat willnow bedescribed. 'Y Suitably mounted onl the t'opof the shelf 23 is a supporting plate` 2li having an interiorly threaded collar 25 y'to which is attached the pipe 26 that surrounds the downwardly extending pump shaft 21. The pump shaft 21 has at its upper en d reversely threaded portions 27'and 28, and 29 designates a collar threaded on the portion 27 and held in ad-l justed position thereon by a, set screw 30. The collar 29 and with it pump shaft 21 are supported on the plate 24: preferably through ball bearings'31. Mounted at the upper end of the-'pump shaft 21Y is a plate32 which is turned down tightly against the collar 29 and because of the lreversely threaded `relationshipV ofthe portions 27 and 28, the-plate 32 is locked against the'collar 29. f v Attached to the lower end of the motor shaftk 33 is a plate Saprovided with -oppositely arranged pins. 35 while 36 designates oppositely arranged pins formed on theplate 32, disposed between the pins 3,5. 37 designates a yieldableinterlocking member preferably in the form ot a washer of leatheror like 5 material, having a seriesy of openings 38 arranged to receive the pins and 36 and thus establish an interlocking driving connection between the motor shaft 33 and the pump shaft 21. The yieldable washer 37 allows a slight play between the connected shaftsfso that absolute alinenient between them is not required, although apositive and satisfactory driving connection is established between the motor shaft and the pump shaft. This varrangement permits quick assembly of the parts, and enables moving the motor and motor shaft without disturbing the pump shaft, it being understood that the motor is mountedin a frame 3 9 thatl rests upon the supportingplate 24 onthe shelf 23, and held thereagainst by any suitableY means.
For a `complete,understanding ot' the invention,-it` is to-be understood that the beverage is drawn through a .dispensing tube which may be of'glass or suitable material, and is supported in and extends through the side wallof the transparent display receiver.
AThis dispensing tube is movable into a position to intercept the stream of beverage'as it discharges from outlet 9, and it is highly desirable to close the dispensingtube when it is not in dispensing-position, in order to prevent travel of warm air from the outsidev atmosphere into the display'receiver during the This may be accomplished by forming the dispensing .tube in such a fashion thatwhen it is out of dispensing position, a liquid ,seal
vof air inward. v
A preferred arrangement for accomplishing this is illustrated in Figures l, 6, 8,9"and l1 to 15 inclusive, in which'the barrel 41 is held lixedly in an opening in the side walll of exterior threaded sleeves 42 and 43 and a threaded locking collar 44. Arranged within said barrel for turning movement. isV a A' split bushing consisting of two sections 45 heldV together by the screws 46 and includingY an eccentrically .disposed opening 47 within which the dispensing. tube is clamped tightly.
The dispensingtube includes a central `or l, clamped portion 48 and an outlet 49. The central clamped portion 48`terminates at its inner end in'an inwardly and upwardly extending portion 50, see `Figure' 13, which latterterminates in a horizontally extending portion 5.1 having an inlet opening 52 disposed directly above thelbeverage discharge pipe 9 when the dispensing tube is in dispensing position, as in Figures 11 and 13.
The split bushing includes a lian-gev 53, see

is automatically afforded to lprevent passageV the displayy receiver by meansrof interior and .thence upwardly, as shown,
charge tube. To move the latter out of'dispensingposition, the operatorggrasps the outlet portionk 49, turning the dispensing tube Y and with it the bushing in which it is clamped,
thus moving the dispensing tube from the position shownin Figures 11 and 13 to the position shown i-n Figures 12 and 14, in which, the horizontal portion-51 is moved` to a vertical position and the opening 52 is out of the path of thebeverage. i p Y Y vVith the dispensing tube in this position theportion extends downwardly andthe bend between portion 5.0 and portion 51, which latter extends then upwardly as shown in Figures 1 and14, affords a trap or pocket for holding lthe beverage 'remaining in 'the dispensing tube.- Since position, portionl extends upwardly, the remaining beverage cannot flow Vback into the` displayY receiver but fis held in thedispensing tube Vand closes the passage vtherein so. as lto. prevent travel of air from outside of the display. receiver through* the dispensingtube to the interior of the display receiver. j
rlhis result can be accomplished ina variety of ways, and a modilication of the structure withthe parts inthis 18 inclusive, in which the dispensing tube is slidable in and out withinits supporting barrel and at the same time may be turned. The dispensing tube of this arrangement is indicated at 61, being slidably and rotatably mounted within the barrelv 62 .and held in normal or outward position by a spring`63 housed in any extension 64 of lthe .barrel and engaging a suitable collar 65 onpthe dispensing tube. At its inner end,- kthe dispensing tube is formedwith an indentation 66 affording a reduced cross-section 67, while 68 is the inlet opening through which the beverage enters when the tube is in ,dispensing"position, as shown in Figure 17. l/Vhen the operator releases the dispensing tube, and atzthe Vsame time turns it into the position shown` in Fig-V ure 18,-thebeverage remainingin the'tube pockets'at its lower end as. shown vin :Figure 18, and thus affords a seal.
Figures 19 and 2O `disclose vanothermodiisfmade in two;pieces,rdesignated at 71 and A72, and suitably held together' by a rubber gasket 73. vThe-inner portion 72 of. the dispensingtube is curved first downwardly and terminating in downwardly directed inlet 74 that -is 'posi-- tionable over the stream otbeveragei in the display receiver. asin Figure19. The-outer portion 7.1 of the.. dispensing 'tube `carries a sleeve 75 that is movable'in apocket inthe bushing 7 and isheld -noimaly in outermost position by a spring 77, suchoutward movement Vof the dispensing tube being limited'by the inner portion 72 striking' againstwasher 78.. To dispense the-beveragewith this-'form of construction, thedispensing tube'is pressed its ilo
ed arrangement in whichth'e dispensing tube l inwardly by the operator, as shown in Figure 19, causing beverage to flow from the outlet 79 as long as the dispensing tube is held in this position. vThen released, it assumes the position shown in Figure 20, and the remaining beverage at the bottom of the inner portion 72 forms a seal, asshown in Figure 20, preventing passage ofvair from the outside to the inside of the display receiver when the dispensing tube is out of dispensing position.
Figures 21 and 22 show still another form of construction in which the dispensing tube is made in one piece, including at its inner end a downwardly extending U-shaped portion 81 and an upwardly extending Ushaped portion 82 terminating in an inlet 83, the opposite end of the tube being formed tok afford an outlet84. The tube is slidable in a sleeve S6 that is held byscrews'l'? within the surrounding collars. 88 and 89 which serve to clamp the sleeve `86'tol the wall 90of the display receiver.
Clamped on the'tub'e is a split collar 91V 1 which isrecessed interiorly, as shown in Figure 22, andfitted in sai'dV recess is a spring 92, the opposite end of which engages the sleeve 86, the spring 92 thus serving to hold the dispensing tube normallyV in its outermost position, as shown in Figure 22. For dispensing, it is pushed inwardly against the action of spring 92, as shown in Figure 21, and when -out of dispensing position, thev remaining beveragein the bottom U-shaped portion 81 seals the passage and prevents ingress of air through the tube to the display receiver.
Figures 26 to 28 inclusive disclose an additional modiiiedarrangement of dispensing tube formed in one piece and including a horizontal portion 95 connected by a. branch 96 with an upwardly inclined portion 97, see
Figure 26, the. portion 97 being in turn connected by a branch 98 with a downwardly extending inlet 99 when positioned as shown in Figure 26. `With this arrangement, the tube is operated'by turning it about Va horizontal axis, for which purpose the horizontal portion 95 of the tube is supported in the sleeve 101 and collars 102 and has a turning movement therein. When the dispensing tube is Apositioned as shown in Figure 26 witli the outlet 103 extending downwardly, beverage passes from pipe 104; to the inlet 99 o-f the dispensing tube and thence through thelat ter. lvhenthe dispensing tube is turned to the position shownin Figure 28, the inlet 99 is out of the pathof the stream of beverage and the Vremaining beverage is trapped in the portionv9'7 which is then disposed horizontally at the lowerm'ost'point, as shown in Figure 27, so that the passage through the tube is sealed against air.
