Patented J an. 2, 1917.

Application filed April 26,1915. Serial No. 23,929.

To all whom t may concern; 4

Be it known thatl I, CHARLns Donnnvs, J r., a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have inventedcertain new anduseful Improvements in Liquid-Dispensing Apparatus, of which the following is a description, referencebeing had to the accompanying drawings, lwhich form a part of my specification.

My invention relates to an apparatus adapted to be put into operative condition through the action ofi a suitable coin inserted therein, whereby liquids or beverages, in predetermined quantities, may be measured out or dispensed through proper operation of the apparatus; the purposeof the invention being to provide a simple and elflcient construction adapted to withstand improper manipulation and which will be positive in its operation when provided with a suitable coin; the apparatus being adapted for use in connection with any liquid-holding vessel or receptacle.

In the drawings, Figure lis a side elevation of my improved apparatus shown secured to a liquid-holding receptacle, only a portion of the latter 'being shown. Fig. 2 is a vertical sectional view of the apparatus, taken on the line 2 2 of Fig. 4, and looking in the direction of the arrows., Fig. 3 is a side elevation of the lower or valve-portion of the apparatus, showing the coin-receiving side `thereof with the side wall or cover removed, taken on the line 3 3 of Fig'. 4, as indicated by the arrows. Fig. 4

is a longitudinal sectional view taken on the.

line 4 4 of Fig. 3, looking in the Adirection of the arrows. Fig. 5 is a vertical sectional view taken on the line 5 5` of Fig. 4 looking in the directionV of the arrows, with one of the disks removed. Fig. 6 is a detail sectional view of the valve shown in one of its positions, namely the position for draining the liquid from the liquid receptacle. Fig. 7 is a detail view of the valve and operating mechanism, the latter being shown in side elevation. y

My apparatus is intended for use in connection with any suitable liquid-holding vessel or receptacle, such as barrels, kegs, and the like; a portion of a vessel being illustrated at 10 in Fig. 1, mounted on any suitable stand or support indicated at 11. The apparatus contemplates the liquid being fed thereto through the action of gravity, and, therefore, is secured to the vessel or receptacle 10 at a point adjacent the lower part thereof. The attachment is adapted to be made by means of a suitable supply tube or pipe 12, the free end whereof is shown threaded so as to permit the apparatus to be removably secured to the receptacle. In order to permit a proper flow of the liquid or beverage into the receiving or measuring portion of the apparatus, through the action of gravity, the supply tube or inlet member 12 is preferably bent downwardly, as indicated, so that the upper portion of the receiving ,portion of my improved apparatus will be substantially in the same horizontal plane as the lower part of the liquid or beverageholding receptacle 10. The lower end of tube or pipe 12 connects with a suitable valve-housing or casing 13, which islsomewhat in the nature of an inverted T, so as to providev the three passages or ports 14, 15 and 16, seev Figs. 2 and 6; member 12 being in communication with port 14. The port or passage 15 extends upwardly and preferably terminates in a flared orifice 15a. The orifice 15a communicates with a suitable measuring vessel or member 17, secured thereon. The receiving member or vessel 17 comprises a glass portion suitably incased, thus enabling the manipulator to see the How of the liquid. The glass vessel or tube is held in proper position by a metallic casing or open-sided housing. The lower or rim portion 19 of the metallic casing is adapted to screw onto the upwardly presented portion of the valve-housing 13, as indicated at 20; the sides of the metallic housing or casing is formed so as to provide open or cut-out portions, andthe side metallic portions of the outer casing, shown at 21 in Fig. 1, terminates at their tops in the dome-portion .In order to effect proper' fluid-tight connections between the cylindrical glass portion and the metallic portions at both ends thereof, I provide the washers or gaskets 23 and 24 at thek lower and top sides of the receiving member 17, as shown in Fig. 2; the washer 23 at the lower end of the cup being arranged on the flared wall of the orice 151 so that when the metallic casing or wall of member 17 is lirmly screwed down on the upwardly presented portion of the valve-casing, the washers 23 and 24 will be compressed between the ends of the glass cylinder or wall and the valve- `casing at the lower end and between the glass cylinder and a suitable flange 22a provided on the interior of the dome-portions 22.

In order to permit the proper flow of liquid into the receiving-member 17, it is necessary to provide means for ingress and egress of air. As an exemplification of one form of such means, I show the dome-portion 22 provided with a depending boss 25, having a port 26 extending therethrough. Suitably secured to the boss 25, for example, by being screwed thereon, is a valve-casing or ferrule 27 having radially disposed ports 28. The ferrule or casing 27 is provided with a suitable valve as at 29 normally in contact with the lower part of the ferrule or casing 27. The valve 29 is provided with Va .depending stem 30, to which is secured able nut 35.

a suitable float-member 31. In order that the float-member 31 may be adjusted into different 4planes within the receptacle or receiving-member 17, the stem 30 is shown threaded and the iioat-member adjustably held on the threaded stem in any suitable manner. The inner orifice of port 26 is preferably flared, as indicated, so as to provide a proper seat for the valve 29 when the latter has been forced upwardly into closed position.

The valve-casing or housing 13 is provided with a valve 32 preferably of the Vtapered cylindrical type, provided with the intersecting, right angularly disposed ports 33 and 34, see Figs. 2 and 6, which, 'when the valve is properly operated, will alternately register with the passages 14 and 15 and with passages 15 and 16, respectively.

r1`he valve 32 is provided with trunnions 32L and 32h; the trunnion 32L being preferably screw-threaded so as to receive a suit- Surrounding the trunnion32a is a coil-spring l36 which presses against nut 35 and against a suitable vwasher 37 which is also mounted on the trunnion 32@L and fits against theV side wall of the valvecasing 13, see Fig. 4. By screwing nut 35 onto the trunnion 32a, spring 36 is comj pressed against the washer 37, thereby yieldingly maintaining valve 32 in proper position; any slight wear of the valve and valveseat being taken care of by the action of vspring 36, which tends to move the valve 32 toward the spring end, as is clearly evident, thus maintaining a liquid-tight conwhich is pivotally mounted at 42. The pawl 41 is doubleended, being in the form of a bell-crank lever, with one end of the Y p'awl provided with an extension or lug 41'LL adapted to pass through the arcuate slot 43 in disk 40. The extension or lug 41a on the pawl 41 has a spring 44 secured thereto on the opposite side of the disk 40, as shown in Fig. 3; the other end of the spring 44 being suitably secured to the disk 40 at the point 45, see Fig. 3. The tendency of spring 44 is to hold the pawl 41 in the normal position illustrad in Figs. 3 and 5, namely with the extension or lug 41a at the lower end of arcuate slot 43.

The enlarged end of valve 32 is provided with a circular flange 46, either made integral therewith 'or rigidly secured thereto, shown in Figs. 4 and 7 and in dotted lines in Figs. 3 and 5. The periphery of the flange 46 is provided with a segmental cutaway portion or groove 46a, see Fig. 7, and shown in dotted lines in Figs. 3 and 5. The pawl 41 is so pivoted on the disk 40 that it will engage with the ends of the slot 46a, so that rotation of disk 40, induced through rotation Yof hand-wheel 39, will, under certain conditions, impart movement to disk 46, and, therefore, to valve 32. The pawl 41 is normally held in the position indicated in Figs. 3 and 5, namely with the end, to which spring 44 isvsecured, extending into the segmental groove 46a. It is evident from Vthis construction that movement of the hand-wheel 39 toward the right in Fig. 3, before a coin has been inserted, will cause the disk 40, carrying pawl 41, to rotate toward the right in Fig. 3 without imparting movement to disk 46 secured to valve 32, because the free or coin-engaging end 41b will be in such position as to move freely across the outer periphery of disk 46 without engaging the shoulder or adjacent end of the groove 46a. On the other hand, movement in the opposite direction of disk 40 would bring the spring-controlled end 41n of the pawl 41 into engagement with the shoulder or opposite end of the segmental groove 46;L in disk 46 and cause the latter, together with valve 32, to rotate in a similar direction as disk 40, if valve 32 has previously been moved fromt its normal or draining position illustrated in Fig. 3.

The mechanism just described is inclosed y by the cover-plate 47, see Fig. 4, which is so formed as to provide a chamber. The cover-plate 47 is preferably removably secured to the annular portion 13n of the valve-case 13; the latter being shown provided'with bolt-receiving lobes at 13b, which receive bolts whereby the cover-plate 47 may be secured in place. rIhe cover-plate 47'is also provided with a coin-receiving chute 43see Figs. 3, 4 and 5, which is so formed as to induce the coin to roll down into the chamber formed by the cover-plate 47 in the manner as illustrated vin Fig. 3 where a coin is indicated atA. The coin A ispermitted to enter the chamber in the manner vshown in Fig. 3 when the disk 40 has been rotated so as to bring the segmental flange 40a into the position shown in Figs. 3 and 5, that is, away from the inner orifice of the passage in chute 43. The flange 40n prevents a coin passing to the opposite side of pawl 41, namely to the left in Fig. 3. Disk 40, as well ashand-wheel 39, are held against complete rotation by the lip 40b secured to disk 40, see Figs. 3, 4 and 5; the lip 40b being adapted to engage with the Banged side of cover-plate 47, the latter being segmentally cut away as is also the rim 13a of valve-case 13, see Figs. 3 and 5. 1t is evident from the construction trat hand-wheel 39 and the correlated parts can merely be given a partial rotation commensurate with the rotation necessary to bring the passages 33l and 34 of valve 32 into register either with ports 14 and 15 or with ports 15 and 16.

1f a coin of suitable character has been inserted in coin-chute 4S, and hand-wheel 39 has been so rotated as to bring flange 40a away from the inner orifice of chute 48, namely to the left in Fig. 3, or to the right in Fig. 5, the coin will come into engagement with the free end 41b of pawl 41 .and also with the circumferential wall within the chamber, so that proper or clockwise rotation of hand-wheel 39, as illustrated in Fig. 3, will cause the coin A; to become wedged between the circumferential wall of the chamber and the pawl, thereby forcing end 41b of pawl 41 downward and into engagement with the shoulder or end wall of groove 46a in Ldisk 46. This will cause the disk 4G, .together with valve 32, to rotate with disk 40 and hand-wheel 39. rThe end 411 of pawl 41 will remain in engagement with the shoulder or end wall of groove 46:L until the hand-wheel 39 and disk 40, as well as disk 46, have been rotated far enough to permit the coin to drop through the slot 49 formed in the bottom 50 of the housing B which surrounds the valve and valve-operating mechanism just described. As the annular rim 13L and the fiange-portion` of cover-plate 47 are cut away at the lower sides, the coin is permitted to slide out of the chamber formed by cover-plate 47 and through slot 49. i

The housing B is provided with a coinreceiving receptacle C, suitably secured and locked in place by any suitable mechanism that will prevent undue access.

Fort 1G of the valve-case 13 is shown provided with a suitable discharge member or spout 51 which extends through the side wall of housing B, as shown in Figs. 1, 2 and 3.

' through The operation of my improved apparatus is as follows: The tube or pipe 12 having been properly inserted or connected with the liquid or beverage-holding receptacle 10, liquid may then be withdrawn from the receptacle by inserting a suitable coin edgewise in chute 48 so as to permit it to roll downwardly through the passage. Handwheel 39 is then rotated to the right in Fig. 3 so that the coin, as indicated at A, will force the end 41) of pawl 41 into the groove 46a and cause valve 32 to rotate with the hand-wheel, the rotation of the latter being limited by means of lip 40" on disk 40. This rotation of the valve 32 will bring port 33 of the'valve into register with port 14 which communicates with pipe or tube 12; while the intersecting or right angularly disposed port 34 of the valve 32 will be brought into register with the port 15 of the valvecasing, thereby establishing communication between the liquid-holding receptacle 10 and the liquid-receiving cup or portion 17 the describedv position of the various ports being disclosed in Fig. G. llVith the valve in" the position just described, it will be seen that communication with spout or dischargemember 51 will be closed off. rThe liquid will flow through the valve and upwardly into liquid-receiving cup or member 17 until it reaches float-member 31 and causes floatmember 31 to move upwardly. rThe upward movement of float member 31 will force ball valve 29 onto its seat 25, and thereby close the air-port 26. With valve 29 in closed position, the further egress of air from liquid-receiving cup 17 will be prevented, and the pressure in the upper part of cup 17 will prevent further flow of liquid from receptacle 10 and through valve 32. Hand-wheel 39 is then rotated in the opposite or counter-clockwise direction, made possible by the previous releasing of the coin slot 49. The moment the coin has been discharged into the coin-receiving receptacle C, the spring-controlled end 41a of pawl 41 will move into engagement with the opposite end of groove 4Ga of disk 4G and cause valve 32 to rotate with hand-wheel 39 and disk 40 a distance sutlicient to bring 7i '5 port or passage 34 of valve 32 into communication with port 16 of the valve-casing and therefore also with spout 51, while passage or port 33 will be moved into register with the port 15 of valve-casing 13, thereby establishing communication between the receiving portion or cup 17 and the spout 51 and allow the liquid to flow from the cup through the spout and be received by the manipulator. Movement of the valve into registering positions is determined by the lip 40b on dislY 40. With the valve in the position just described, communication with port 14, and, therefore, with pipe or tube 12 and receptacle 10 will be shut off. The i draining' or dispensing position of the valve is illustrated in Figs. 2 and 4. Y

It is evident from the construction shown and described that the quantity of liquid to be dispensed with each insertion of a coin may be controlled or regulated by means of float-member 31; that is, a smaller quantity of liquid will be obtainable when float-member 31 is lowered on the stem 30 of valve 29; because the moment valve 29 is moved upward to its seat 25, the pressure within the cup or receiving portion 17 at the upper end will be such as to prevent further flow of liquid into the cup. It is also apparent from the construction that it is impossible to secure a further supply of liquid without inserting an additional coin, because reverse or clockwise movement of hand-wheel 39 will not cause valve 32 ,to rotate therewith, so that ports 33 and 34 will not be brought into the position shown in Fig. 6, due to the fact that pawl 41 cannot be tilted without the wedging action of a coin inserted between it and the side walls of the chamber. I have also shown my improved apparatus provided with suitable registering mechanism D which may be of a well known type and suitably mounted on the bottom 50 of the housing B. rIhe operating shaft of the registering mechanism D is shown provided with a suitable arm 52 pivotally connected by means of a link 53 to an arm 54, which latter is rigidly secured to the trunnion 82EL ofthe valve 32, so that each forward movement of valve 82, into the position assumed when the liquid is being drained from the cup 17, will cause the registering mechanism D to operate and register an operation of the valve. Such registering mechanism may be found desirable to indicate the number of coins that should be contained within receptacle C.

I have shown and described what I believe to be the simplest and best form of my invention, but the construction may be modilied in certain respects without, however, departing from the spirit of my invention, and I do not wish to be understood, therefore, as limiting myself to the exact construction shown and described.
