12 Claims. (Cl. 221-93) This invention relates to vending machines, and more particularly to a type in which a succession of different articles or materials will be rendered available to a purchaser in required sequence upon insertion of one or more coins into the apparatus. Reference is particularly made to an apparatus by which ingredients for making a beverage, such as coffee, chocolate, cocoa or the like, a cup for containing the beverage, and a fluid, such as water of the required temperature, Will be successively made available in proper sequence for the purchaser.

It is one of the objects of the invention to provide an apparatus for dispensing both cups and predetermined quantities of a fluid, such as hot Water, which apparatus can be readily applied or attached to a well known type of package vending machine, thereby materially extending the usefulness of such machine and enabling it to cooperate in the dispensation of materials for making beverages.

It is another object of the invention to provide a mechanism by means of which paper cups may be successively dispensed, with the means for causing the dispensing of each cup being operative to control a switch by which the subsequent dispensing of a predetermined amount of the fluid will be had.

It is an object of the invention to provide means by which a number of cups may be successively dispensed and the amount of liquid to be thereupon dispensed shall be regulated according to the delivered number of cups.

With these, and other objects to be hereinafter set forth in view, I have devised the arrangement of parts to be described and more particularly pointed out in the claims appended hereto.

In the accompanying drawings, wherein an illustrative embodiment of the invention is disclosed,

Fig. 1 is a front elevational view of the improved dispensing mechanism in its normal position of rest;

Fig. 2 is a similar view, but showing the parts in the position which they assume for the dispensing of a cup with the fluid-dispensing means freed for the dispensing of a predetermined quantity of fluid upon closing of a manually-operated switch;

Fig. 3 is a sectional view, taken substantially on the line 33 of Fig. 1', looking in the direction of the arrows;

Fig. 4 is a sectional view, taken substantially on the line 4-4 of Fig. 1, looking in the direction of the arrows, and

Fig. 5 shows the electrical circuit for controlling the flow of the fluid.

The apparatus illustrated in the drawing is primarily, although not necessarily, designed for attachment or connection to some known type of package or article-vending apparatus by means of which, on the insertion of one or more coins, an article or package will be dispensed. Since such type of machine is known in many forms, the mechanism thereof is not herein shown and described, except to state that the element shown at 1 indicates a delivery chute forming part of, or connected to a machine fpom which the articles are successively dispensed. At 2 is nited States atent shown one of the articles, which might be a packet or a container enclosing the dry ingredients for making a cup of coffee or other beverage. When such article has been freed for delivery out of the vending machine, it is arranged to pass and contact with a trigger or finger 3 constituting the actuating member of a micro-switch 4 which controls, by means of the wires 5 extending from a source of current, the energization of a solenoid 6 mounted on a base plate 7 attached to the vending apparatus. In the normal or inoperative position of the apparatus, the core 8 of the solenoid is held in its extended position as shown in Fig. 1, by means of a coil spring 9 having one end attached to an eye 10 secured to the core 8 and having its other end attached to the fixed pivot pin 11 on which an arm 12 is pivotally mounted. The arm 12 is formed with a lug 13 from which a stud 14 extends, and one end of a link 15 is adjustably connected in the stud while the other end of the link is formed with a loop 16 extended through eyes 17 provided at the end of the solenoid core 8.

Pivotally mounted at 18 on the arm 12 is a pawl 19, normally held in the position shown in Fig. 1 and against a stop pin 20 provided on the arm 12, by means of the coil spring 21. The pawl 19 is adapted for engagement with the notches 22 provided in the edge of a ratchet wheel 23 rotatively mounted on a stud shaft 24 secured to and extending from the base plate '7. This arrangement is such that upon each pivotal swing of arm 12 under the action of the solenoid and from the position shown in Fig. 1 to that shown in Fig. 2, the pawl 19 engaging in one of the notches 22 will rotate the ratchet wheel 23 in a clockwise direction for a predetermined distance. Carried by the ratchet wheel 23 is a cam member 25 which, in the position of rest of the apparatus as shown in Fig. 1, has its cam edge 26 engaging against a laterally-extending pin 27 projecting from the face of a pivoted locking member on latch 28. Said locking member or latch 28 is pivoted at 29 on the face of a sliding bar 30 which is slidable in

guides

31 and 32 mounted on the face of the base plate 7. A coil spring 33 has one end attached to a pin 34 on the locking member 28 and has its other end fastened to pin 35 provided on the sliding bar 30. The spring 33 normally tends to pivot the locking member on pivot pin 29 in a manner to cause its forward end or nose 36 to be brought down to the position shown in Fig. 2 whenever theratchet wheel 23 has been rotatively moved to an extent to cause the cam 25 to be swung sufliciently to permit upward swing of the rear end of the locking member as shown in Fig. 2. When the apparatus is in its position of rest as shown in Fig. 1, the cam, in its lowered position, maintains the locking member raised. It will be noted that at the rear end of the locking member 28, there is provided a tooth 37 which tends to rotate the ratchet wheel 23 backwardly or in a counter-clockwise direction when the sliding bar 30 is moved to the right.

At 38 is shown a pivoted lever, which is pivotally mounted on the shaft 39 and which shaft may extend to the outside of the casing in which the described mechanism is contained and may be provided with a knob or handle 39a (Fig. 4) by which the lever 38 may be swung from the position shown in Fig. 1 to that shown in Fig. 2. A coil spring 40 has one end attached to. a flange 41 on the lever 38 and has its other end attached to a pin 42 on the base plate 7, and said spring 40 normally holds the lever 33 in its retracted position, or that shown in Fig. 1. A stop pin shown at 38a limits the swing of lever 38 in an opposite direction.

At 43 is shown a cup-delivery device of known construction, and such device is constructed to deliver a cup upon each movement of an operating arm 44 movable in a slot 45 formed in the casing of the cup dispensers. Said arm 44 is connected to the upper end of a rod 46 having its lower end secured at 47 in a lug 48 extending laterally from the sliding bar 30. This arrangement is such that upon each movement of the arm 44 to the right by the sliding movement of the bar 30 in that direction, a cup will be dispensed-from the cup-dispenser 43. The coil spring 49 which retracts bar 30 as well as the arm 44 has one end attached to the rod 46'and has its opposite end attached-to alug 50 mounted on or formed out of the base plate 7, and the spring 49 tends to retract the slid ing bar 30-to the position of Fig. 1 while swinging the cup-dispensing arm 41 to its retracted position also shown in Fig.- 1.

Mounted on the sliding-bar 30 is a pawl 52, pivoted at 53 on said bar, and the coil spring 54 normally tends to hold thepawl SZ-against a stop pin 55 provided on the bar 30. The pawl 52 is adapted to engage with a ratchet wheel 56 secured to anotched disk 57 and rotative in company with the disk and with a shaft 58 on which the disk and ratchet wheel are mounted and to which they are frictionally coupled. The ratchet wheel 56 and disk 57 aremounted as shown in Fig. 3; wherein they are frictionally held against a rubber facing 59 provided on a drum 60- secured on the shaft 58. The ratchet wheel 56 and the notched disk 57 are held against the facing 59 by a coil-spring 61 arranged around shaft 58 betweenthe 'predetermined periods through the medium of two switches, one of which is shown at 64 and the other at 77. Said switch 64 is controlled by an arm 65 which carries a roller 66' at its free end and said roller contacts the peripheryof the disk 57. When the roller 66 is engaged in a notch 67 formed in the periphery of the disk 57, the arm 65 is in its raised position so that the switch is at this time in open condition and will so remain as long as the roller is located in-the notch, and the circuit to the electric motor 63 will be open not only because of the fact that switch'64 is open but because of the fact that the manually controlled switch 77 is also open. The switch 77 is controlled by a push button 68 which requires maintenance of finger pressure on it in order to keep this switch closed.

Both of the switches 64' and 77 not only control the operation of the electric motor 63, but also control the flow of fluid to be dispensed. This will be clear from Fig.- 5, wherein the dispensing faucet or tap for the hot water or other fluid is shown at 70, the same being operated by a solenoid valve 71. From the wiring diagram therein shown, it' will be apparent that while the roller 66 carried by the switch arm 65 is in the notch 67, the

switch 64 will be open and at this time manual closure of switch 77 will have no eifect on-either the operation of motor 63 or the solenoid valve 71; However, whenever the roller 66 is out of the notch 67 and rests against the periphery of disk 57, switch 64 will be closed and the dispensing of fluid will be had by finger pressure maintained upon push button 68 to keep switch 77 closed. Thus, while both switches 64 and77 are closed the disk 5'7 will beslowly rotated clockwisely for a given period of time to bring the notch 67 to a position to engage the roller 67 and permit rising of the switch arm 65 to secure off position of switch 64. When this occurs the flow of water or other fluid from the faucet 70 will cease, and a predetermined quantity of the liquid will have been dispensed from the faucet 70'. I

From the foregoing, the operation of the described apparatus will now become apparent. When one or more coins are deposited in the package vending machine to which the herein-described apparatus is attached and of which it forms a part, a package 2 will be dispensed.

For example, the package 2, when being delivered from the vending apparatus, will contact the trigger 3 and momentarily close the switch 4. This will cause energization of the solenoid 6, causing the core 8 thereof to be retracted toward the right as shown in Fig. 2.

When the solenoid 6 is energized, its core 8 will be drawn toward the right and through the link 15, it will swing the arm 12 in a counter-clockwise direction. As the arm 12 is so moved, the pawl 19 carried by it will engage the ratchet wheel 23 and will rotate the same clockwisely and for a predetermined distance and sutlicient to so elevate the cam 25 that said cam will permit the locking member 28 to have its rear or toothed end slightly elevated and thus have its forward nose 36 moved downwardly to an extent as to cause the operating lever 38 to impinge against the nose 36 when said operating lever is manually rotated by manipulation of the handle 39a. As the operating handle 39a is turned to swing the lever 38 to the right, the lever 38, engagingagainst the nose 36 of the locking member, and which is at this time acting as an abutment, will cause the slidable bar 30 to be slid lengthwisely through its

guides

31 and 32 toward the right. This sliding movement of the bar 30 will move the arm '44 on the cup-dispenser 43 in a manner to cause one of the cups to be delivered from the dispenser to the customer. Movement of the bar 30 as above described willalso cause ratchet wheel 23 to be moved counter-clockwise by engagement of tooth 37 with one of the teeth of the ratchet wheel as shown in Fig. 2. When manual pressure is relieved on handle 39a and the slidable bar 30 is moved to the left by the action of spring 49, the pawl 52 carried by the bar 30 engages one of the teeth on the ratchet wheel 56 and causes said wheel and the disk 57 attached to it to be rotatively moved independently of shaft 58 for a predetermined distance in a counter-clockwise direction, thus moving the notch 67 away from the roller 66 and causing the switch 64 to close. As bar 30 ismoved to the right, the tooth 37 on the locking member'28; engaging one of the teeth of the ratchet wheel 23' will rotate the ratchet wheel 23 for a predetermined'distance backwardly or in a counter-clockwise direction and for substantially the same distancethat the ratchet wheel was previously rotated in an opposite'direction by the pawl 19, to therefore restore the'cam 25 to locking position shown in Fig. 1. Thereafter the handle 39a and lever 38 connected thereto can be freely turned without causing any movement of the slidable bar 30 until another package 2 has again caused the solenoid 6to' be energized.

It will, at this point, be noted'that the purchaser has now received as many packages 2 of the beverage-making ingredients as he has paid for by the deposit of a suitable sum of money, and has conditioned the apparatus to reserve one cup for each purchase. Each successive purchase of one of the packages 2 conditions the apparatus to reserve one cup by moving the cam member 25 one notch in a clockwise direction. Then, each time that knob 39a is turned to the right to release a cup, the cam member 25 is moved one notch nearer to the position shown in Fig. 1 in which position the locking member 28 is located out of the path of swing of lever 38. The apparatus has also been conditioned to dispense a given amount of hot Water or other required fluid, for' switch 64 has now been closed and it will remain closed for the period of time required for the disk to rotatively travel to bring its notch 67 into engagement with roller 66. The disk will start such travel as soon as the circuit-to motor 63 is closed. To close the circuit to the electric motor 23, all that the said purchaser is required to do is to operate the push button 68, holding his finger against it-to keep switch 77 closed until the disk 57 in its travel brings its notch 67 into engagement with the roller 66. If the purchaser at any time while drawing the water in the manner above pointed out releases his pressure on the push button 68 the flow of water or other liquid will cease as will movement ofthe disk 57. On again pressing the button 68 and holding the finger against it, the flow of water will be resumed and will continue until the notch in the disk reaches the roller 66. Thus, the user is always assured of a definite amount of the fluid even if he removes his finger from the button one or more times before his cup is filled.

in case anumber of successive purchases of the ingreclient packages 2 and cups therefor are had without drawing the water or liquid supply for such number of cups, the amount of water to be dispensed will be accumulated by the successive movements of the disk 57 bringing the notch therein farther away from the roller 66. Thus, in a case of this kind it will be apparent that the travel of the disk to bring its notch into engagement with the roller will be extended to such an extent that the flow of the fluid will be multiplied and one after another of the purchasers can fill his cup by merely placing it under the tap and pressing the button 68 until each cup is filled, each of the successive purchasers being assured that he will secure a full cup of the fluid.

Having described a single embodiment of the invention, it is obvious that the same is not to be restricted thereto, but is broad enough to cover, all structures coming within the scope of the annexed claims.
