BEVERAGE-VENDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 780,560, dated January 24, 19 05.

Application filed December 18, 1901- Serial No. 86,367.

the accompanying drawings, and figures of reference marked thereon, which form a part of this specification.

My invention relates to machines designed and equipped for dispensing cold water and other cold drinks; and it consists of an inclosing case, a holder therein adapted to hold a plurality of cups suitable for serving drinks therein, of a refrigerator whereby the water or other drink is cooled, of a detachable receptacle for holding in store the water oroth'e'r drink to be dispensed, of a measuring-valve adapted to be actuated to supply the'cups with the water or other drink, and of a lever-actuated mechanism, whereby the cups are brought into position to be ,fltied. thevalve operated -to fill the cups with ,-.the liquid, and a door opened whereby the cups may be taken by their purchaser, which mechanlsm is normally retained locked against actuation, but adapted to be unlocked, so as to be operated by dropping a coin into a slot in the machine-case and by actuatlng a push-slide, thus causing the coin to operate a device whereby said mech anism is unlocked; and the objects of my improvements are to provide a device whereby pure cool drinks may be procured for a nominal price in localities where it is not easily obtained free, to prc vide in the service of the device a clean fresh cup for each individual patron, and to make it possible to dispense such drinks in such manner without the service of an immediate attendant.

Referring to said drawings, Figure 1 is a sectional elevation of the machine, taken on line F F of Fig. 2; Fig. 2, a cross-sectional View on line A A of Fig. 1 looking down; Fig. 3,-a similar View on line B B of said Fig. 1, also looking down; Fig. i, a front exterior elevation of the machine; Fig. 5, a detailed side and partial sectional view of the locking and slotmechanism on line C O of Fig. 2 looking toward the top of the sheet; Fig. 6, a similar View of the mechanism for actuating the cup. lifting and adjusting device and for opening the dispensing-door, taken on the line D D for the upper portion of said view I and on line E E for the lower portion of the view; Fig. 7, a partial interior view of said dispensing-door and the spring-hinge thereof; Fig. 8, a sectional View of the measuringvalve of the machine; Fig. 9, a detailed front view of two of the cup-holding tubes of the machine, with portions broken away to show construction and also to condense the length of the view; Fig. 10, a top planof one of said tubes; Fig. 11, a bottom plan of two of said tubes; and-Fig. 12 a perspective View of one ..oft hedrinking-cups, such as are adapted for use in the machine.

In said drawings, 1 represents the side walls of the case of the machine, having a floor 2, a main side door 3, a top door 4, a dispensingdoor 5, and a coin-collecting door 6.

Placed to cover, and thus inclose, the top of case 1 in rear of door 4: is a refrigerator 7, comprising an inner and outer box arranged to form a chamber between their bottoms and side walls, which is packed with charcoal or other suitable material, as represented in Figs. 1 and 2, and is further provided with an inserted lid 8, having its inserted portion likewise packed. The interior of said inner box forms a chamber 9, wherein ice is placed, as represented in Fig. 1. V In the bottom of said chamber 9 is placed a coil-pipe 10, having its supply branch arranged through an opening in the side of said inner box and extending up through the wall-packing and from said refrigerator, where it terminates with a unioncoupler 11, While the opposite pipe branch but removably retained able receptacle 13, wherein the water or other liquid to be dispensed is placed, which is provided with a pipe 14 and cut-off valve 15, which are through the agency of union 11 coupled with pipe when in service, two parts of said union having side extending perforated ears, (represented at 16,) and valve 15 has its lever shaped to coincide with said ears and likewise perforated, and a pin is placed through said ears and lever jointly and there secured, by means of a lock, as represented, to prevent the removal of said receptacle 13 by persons not in charge thereof. Placed in the case 1 below said refrigerator is an upright rotatable cup-holder comprising an upright shaft 17, stepped in box 18 on floor 2 and held at its. top in a box 19, having arms extending and fixed to the wall of case 1. Spiders 2O 20, fixed on said shaft, as shown, respectively bearing radially-extending arms 21 21, which have fixed to their end portions flat annular plates 22 22, one directly above the other, which plates are made with a plurality of holes open at their outer side, wherein are fixed a plurality of tubes 23, correspondingly open along their outer side, as represented. Said holder thus constructed is so arranged as to be rotated and bring each of said tubes 23 directly under the spout of valve 12. Also attached to the bottom of the lower plate 22 is a plurality of earns 24, which are for the purpose of being engaged .by an uptraveling finger to cause an intermittent rotating movement of said cup -holder. Said cams are attached, respectively, at points between adjaeent tubes 23 and reach under each adjacent tube and are shaped with their depending portion curved to underreach the vertical line of the face or side, opening in one adjacent tube and beveled up to register in line with the opposite adjacent tube side opening. (See Fig. 9.) Said tubes may have removable bottoms 25, (shown in Fig. 9, also Fig. 3,) or said bottoms may be omitted and said cams serve as bottom-supports, as represented in Fig. 11. In the attaching of said cams screws 26 (see Figs. 11 and 9) are placed, through holes in plate 22, down into them,

which swivels them so they may be turned,

as represented by dotted lines in Fig. 11, so as to clear the lower end of said tubes when it becomes necessary to charge them with cups, and as a means of holding said cams in proper operative position dowelpins 27 (see Fig. 11) are placed, through holes of plate 22, down into them.

Case 1 is made with a portion at its front extending beyond the annular line of its remaining portion, as represented in Figs. 2, 3, and 4, wherein an upright frame 28 is placed, which bears at its upper portion a horizontal shaft 29, having fixed thereon a sprocket-wheel 30, and at its lower portion an idler sprocket-wheel 31, and placed on said equidistant fingers 33, which when the chain is actuated come about under wheel 31, first engage against a cam 24, and as they move up cause the engaged cam to be forced sidewise from the path of the engaging linger, which action rotates said cup-holder one tube section. Continued up movement of said finger brings it into the side opening of theadjacent tube 23, and hence against the bottom of the lower cup placed in said tube. \Vhile one said finger 33 is in such service the opposite one is freeand descending, to be brought into position for like service when its fellow has lifted the last cup from its-tube and passed over and out of service. The movement imparted to said chain 32 is intermittent, or only when the machine is operated to dispense a drink.

The case of measuring-valve 12 is made with a covered hand-hole, as shown, to render it possible to place therein its necessary parts, and the side thereof is made with a suitable stuffing-box, wherein a shaft 34 is placed, and arranged extending horizontally (see Fig. 2) on the extending end of said shaft is fixed an arm 35, and on its end within valve-case 12 is fixed a cam 36, which operates against stems 37 and 38 (see Fig. 8) to alternately open valves 39 and 40, respectively, of said stems. Springs 41 42, placed about and impinging cross-pins of said stems, respectively close valves 39 40 when cam 36 so permits. Valve 39 is normally held open and arm thrown back, thus permitting the case or shell 12 to fill from pipe 10. At any time the machine is operated shaft 34 and cam 36 is actuated to permit valve 39 to close and to open valve and permit the contents of case 12 to Ilow out through the case-spout and into a cup supported in a tube 23. Forward from and parallel with shaft 34 is a shaft 43, arranged with one end passing out of case 1 through a suitable bearing, and thereat bears the actuating-lever 44, normally held, by means of a coil-spring 45 on said shaft, in an upright position. Said shaft 43 is suitably supported at its inner portion in a bracket-bearing 46 and has fixed thereon adjacent said bearing a ratchet-wheel 47 and arm 48, (see Fig. 5,) which arm connects arm 35 by means of a link 49, which is slotted over a wrist-pin of said arm 35, so that a partial movement of arm 48 may be had before arm 35 is actuated thereby. Bearing 46 is made with a depending portion 50, to which is pivoted a locking-dog 5. and a trip-lever 52, and in the terminal portion of said part 50 is a barrel, into which is placed a spring-plunger 53, which is made V-shaped atits upper end and arranged engaging yieldingly in a small V- notch in the depending portion of dog 51, and thus holds said dog thrown so either one or the other of its opposite branches may be held to engage wheel 47, slipping plunger 53 from one wheels is a sprocket-chain 32, having two 1 V-notch of the dog to another fellow notch whenever said dog is thrown. In the normal position of the machine parts the inner branch of dog 51 isheld engaging a tooth of wheel 47, as shown in Fig. 5, which locks lever 4:4 against being pulled over forward, and thus operated. When it is desired to operate the machine, a coin is dropped into slot 54;, and by means of the fiat tube 55 it falls and comes to rest in rear of a spring push-slide 56. This slide is then pushed in, which pushes the coin along under andpast lever 52, where it is permitted to then fall farther down said tube and enter a deposit-receptacle 57, fixed to the inner side of the collecting-door 6. As said coin is thus pushed in it lifts the end of lever 52, causingv a side extending pin thereof to engage dog 51 and throw it to disengage its rear branch from wheel 47 and bring its front branch to engage said wheel, and the form of teeth at that side of wheel 47 prevents the return of lever 14: after it has been brought over forward in process of operation until it has madeits full movement forward and abranch 59 of arm 48, which has a side extending portion-,.has engaged the forward branch of said dog and forced it down, thus throwing said 'dog and again bringing its rear branch to engage wheel 47, and thereby again lock lever 44 in its normal position. Also fixed on shaft 13 adjacent arm 48 is an arm 60, (see Fig. 6,) and sleeved on shaft 413 adjacent said arm 60 is an arm 61. Pivoted to arm 60 is a latcharm 62, having a notch which is engaged by a lug 63 of arm 61. Pivoted to arm 62 is a box 6 1, through which a rod 65 is placed,

which rod extends downward and forward and pivotally connects with an arm 66 of the dispensing-door hinge-shaft 67 and is at its upper end slightly longer than the point of box 64, which permits arm 60 to move a fraction of its distance before box 64 engages the stop of said rod end.

Fixed to the end of arm 61 is a chain 68, which passes forward about a pulley 69, thence rearward, and its opposite end is fixed to the periphery of a sheave 70, which is sleeved on shaft 29 adjacent a ratchet-wheel 71, which is fixed on said shaft, and a pawl 72, pivoted to the side of sheave 70, is arranged to engage the teeth of said wheel 71.

In line with one side of sheave 70 and pivotally attached to case 1 is a latch-bar 73, which has one notch wherein the lower end of arm 66 engages, (see Fig. 6,) which looks door 5 closed. A coil-spring 74 holds said latch in action. Apin 75, set in the side of sheave 70, immediately above latch 73, wipes down when said sheave isturned, and thus unlocks said door 5 by pressing said latch down. The spring 7 1 also serves the purpose of returning sheave 70 to its normal position after each actuation. I-Iingeshaft 67 of door 5 has thereon a coil-spring 76, which automatically closes said door at the conclusion of each actuation ofthe machine.

When lever 44 is operated, arm 60, with arms 61 and 62 latched therewith, will be likewise operated, causing arm 61 to draw on chain 68, and thus partially turn sheave 70, when the pawl 72 thereof engaging wheel 71 will turn said wheel correspondingly,and thus actuate shaft 29, together with sprocket-wheel 30 and sprocket-chain 32, causing a finger 33 to move up the length of one cup in a tube 23, thus bringing the top cup in the tube into position for service and to a positionso as to come to rest upon opposite spring-keepers 77. During the first stage of such movement rod 65 does not operate; but when box 64 reaches its stop then said rod is pulled and opens door 5, as stated. Also but a partial movement of arm 60 is required to impart motion to wheel or sheave 7 0 to properly actuate sprocket-chain 32, and in order to prevent too great movement to said chain arm 62 is made so its extending end wipes against the hub of arm 35, so as to'" move it from engagement with lug 63, thus releasing arm 61, and thereby preventing further movement to sheave 7 0, but permitting arms 60 to 62 to continue the full movement, so door 5 will be pulled wide open. As sheave is returned to its normal position pawl 72 runs the teeth of wheel 71 and drops in ready for another like operation. Also chain 68 is paid back so the coil-spring 7 8 of arms 61' 62 can return arm 61 to again latch with arm 62 to be in readiness for a succeeding actuation.

In service each tube 23 is filled with cups 79, such as is shown inFig. 12, preferably made of paper coated on the interior with parafiin, and in each said tube one cup will project from the tube ready for service, so as to compensate for the movement of chain 32 when the said cup-holder is partially rotated, as before stated.

In operation a person drops a coin in slot 5 1, then pushes in slide 56, which unlocks lever 14. He then grasps said lever 14: and pulls it forward and down. The first portion of such lever movement actuates chain 32 and brings a cup into position, as stated, and the last portion of such continued movement actuates the measuring-valve, fills the cup, and pulls open the door 5, so the person may then reach in and take the cup and contents thereof, and as he releases lever 4:4: spring 15 will at once return it and spring 76 will at once close and cause the door 5 to lock closed.

It is intended that the doors of the machine, 7 and especially door 5, shall be fitted to close very close, so as to exclude all dust from the interior of the machine.

In instances where cold water may be had from other sources the receptacle 13 and refrigerator 7 may be omitted and pipe 10 connected direct with such source.

. In Fig. 2 I have represented a register at 80 adapted to be actuated by a crank-arm 81, fixed on shaft 43 through the agency of a rod 82, which register may be of any ordinary type for the purpose of recording the number of actuations of the machine.
