4 Claims. 1

This invention relates to dispensing apparatus and more particularly to apparatus for dispensing cube sugar for use in connection with beverage vending machines and the like.

In machines for vending beverages such as coffee and the like it is desirable to have a selective arrangement for adding sugar to the beverage to suit the taste of the purchaser. While it is desirable to have the sugar dispenser arranged and operated relative to the beverage vending machine where the purchaser at his own election can have his beverage without sugar, or with one or two cubes of sugar, it is also desirable that the total number or" cubes available for any one container or cup of beverage be limited to prevent the cost of the cup of beverage being excessive and also to prevent emptying of the sugar dispenser by the purchase of one cup of beverage.

The objects of the present invention are to to provide a cube sugar dispenser with a discharge port and selectively operated mechanism for controlling said port for delivery or" one cube of sugar at a time; to provide such a dispense with a movable member having a plurality of pockets which is operated to move cubes of sugar into alignment with the discharge port, said HlOV able member being actuated only at each time a cup of beverage is purchased; to provide a cube container arranged to support the weight of the principal portion of the cubes and limit the quantity afiected by the movable member; to provide a cube lifting member moved with the movable member to eliminate bridging of the cube sugar in the container; to provide a sugar dispenser with a discharge chamber separated from the main body of sugar in the dispenser and having such communication therewith as to limit the quantity of sugar cubes in the discharge chamber; and to provide a cube sugar dispenser which is economical to manufacture, efiicient in operation and easily serviced.

In accomplishing these and other objects of the present invention, we have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:

Referring more in detail to the drawings:

I designates a cube sugar dispensing apparatus adapted to be with a machine (not shown) for vending beverages by the cup or like container. The cube sugar dispensing apparatus preferably consists of a container 2 having cylindrical, vertically arranged walls 3, the lower end or which is suitably secured to a bottom member d, illustrated as being rectangular in shape having depending legs 5 with feet 6 on the lower ends thereof adapted to be mounted on a suitable support to space the bottom t above said support suiiiciently for operating mechanism located therebetween as later described.

A suitable cover I is removably mounted on the upper end of the Walls 3 to close the upper end of the container, the cover 7 being removable for servicing of the dispenser by the addition of cubes of sugar to the container.

A funnel-shaped partition 8 is suitably arranged in the container, in spaced relation to the bottom :3, to define a discharge chamber 9 between the partition and the bottom and a storage chamber it above the partition. The funnelpartition preferably has a suitable portion such as a cylindrical, vertical wall it slidabl engaging the interior of the container wall 3, the lower end of said vertical wall it terminating in a downwardly and inwardly sloping wall 52 of substantially conical formation, said wall iii having a central, axial aperture [3 therein for passage of cubes of sugar from the storage chamber it to the discharge chamber 3 as later described.

The partition 2 preferabl rests on a rib or the like is extending inwardly from container wall 3 and spaced from the bottom it to limit the height of the discharge chamber d for movement of cubes of sugar therethrough to a discharge port it; in the bottom l of the container, said discharge port preferably being adjacent the side wall 3 as illustrated in Figs. 2 and 5. A shaft it is rotatably mounted in an axial bore 5? in the bottom 4%. lhe lower end or" the chat extends below the bottom fl and secured to the lower end of the shaft is a coupling 68 operatively connecting the shaft it with a shaft 23 driven by a motor 2 i. The motor 2: is preferably of the type having a gear reduction unit enclosed in a portion 22 of 3 the motor housing whereby the shaft 2% is driven at a relatively slow speed. The actor and gear reduction are secured by suita fastening devices 23 to a bar of a U-shaped oraclzet 25 having the upper ends of vertically esitendii. legs suitably secured as at 2? to the bottom wherein the bar portion of the bracket is spaced below the bottom 6. A earn member 23 is rigidly secured to the shaft it between the upper end of the coupling it and the bottom said cam having lobes and dwells in its periphery for opening and closing a microswitch 3i supported on a bracket 32 in such a manner a roller 33 on the arm of the switch engages the periphery of the earn, the inicroswitch "i being connected into the circuit of motor ill for controlling operation of same as later descr'he". The upper end of the shaft it extends axial the container 2 th ugh the discharge chaniher and for a substantial distance into the storage chamber 58 illustrated. in Fig. 2.

A rotor 35 is arranged in the discharge chainher 9 and co red to the shaft 58 by a key The bottom of the rotor a flat surface Bl which spaced from the upper surface of the bottom t by means of uitable washers or the like 39. The upper portion of the rote" as ill in Figs. 2 and 5, has a flat portio'i shaft said fiat portion t downwardly and outwardly slopin which ternih conical surface -1- portion that extends to the pe rotor. The thickness of the rotor bottom surface and the surface is .referab v slightly greater than the thickness of one or more cubes of sugar as desired. The rotor is pr vided with a plurality of pockets equally spaced around the periphery of the rotor. Each of the pockets extends v rotor and is of sufficient it de t-n for free movement of one cube of sugar through the pocket. A lifting device in the form or a coil spring or the like is sleeved on the shaft it and extends from the flat surface it of the rotor to the upper end of the shaft, said spring being held on the shaft by means of a cap secured as a screw to the upper end of the shaft. The shaft it and spring thereon are of such size relative to the aperture it through which they extend that cubes of sugar will pass between the edge of the aperture and the spring.

Cubes of sugar contained in the storage char! her it are supported on the conical wall it of the funnel member 8, and while cubes can pass through the space between the edges of the aperture 63 and the spring there is a natural tendency for the cubes to bridge the aperture so that no cubes would fall through the aperture. Also the spacing of the of the rotor from the edge of the aperture i8 is such that the cubes of sugar tend to arrange thernsaves in one layer on the upper surface of the lfitql' and slide into the to pockets and not permit additional cup-es flow out over the first layer on stack up on discharge chainher.

Operation of the motor ill rotates the sh ft l6 and the rotor to align one of the po with the discharge opening The neX tion of the rotor again turns t e shaft to move asther pocket 1 the discharge opening 55. structure, there are four poor: ts on the rotor whereby the shaft i rotor 25 are turned e quarter of a revolution on each opera 'on of the motor it. This rotation of the shaft 55 also turns the spring l l which is coiled in such a manner that the rotation provides a 1' 'ng action on the cubes of sugar hearing thereagainst, thereby providing slight agitation. of the cubes in the storage chamber to prevent bridging action, thereby causing the cuhes to move through the aperture 53.

Discharge of cubes of sugar i charge port i5 is controlled s an opening which through on slide is moved into and out of rcgi discharge port it. The ll arranged di oetrically of ccntai the lower face of the bottom The portion of the slide adjacent the opening is slidahly supset as at El and connected to Vi of a solenoid which suitably supper on the bottom slide The intermediate portion of is provided with an elongated openin which the shaft extends. The en shaft ie to resilie': solenoid, the elongated opening being so arranged flat when the solenoid is zed the slide will he toward the solen to ect registry of the opening with the dis-ch portion when the solenoid is dee zed the sp: slide to the other end of its strol: opening id is out of registry wi port is shown in Fig. 2.

A vane is secur to the the openi g vane extends through a sl and lies on the upper Si f hereof and the discharge port it when hopeni g it is out of registry therewith and is moved to discharge port it when the ope registry with said port. The vane p1 of sugar from engaging the ed es port when the rotor 35 is rotated. This ment, together with the thickne s of prevents broken cuhes or pieces with the operation of the In the illustrated str cture, the hot '*'ering with the slide and member El on an inwardly which extends through a slot the container. The vane lower end of a fiat spring end of said spring being secuw fastening devices 32 to the e tainer side wall 3 in vertical :3. vane 58.

ieinber into The wherein the opening is is out of registry with the discharge port E5, the engagement of the slide and stop member swings the vane outwardly on the spring relative to the container whereby the next cube of sugar in the pocket 23 may drop down onto the vane 56 as illustrated in Fig. 2.

In using a sugar dispenser constructed as described in connection with a beverage vending machine, the motor M is connected to a suitable source of electrical energy with the microswitch 3| in one of the leads to the motor, said lead being in parallel circuit with the control circuit of the vending machine in such a manner that when a coin is placed in the vending machine and the electrical apparatus thereof energized a relay 63 is energized to close the circuit to the motor 2! to start same operating, the time element of the energization of the vending machine circuit being such that the motor will operate from such circuit sufficiently to rotate the cam 23 until the roller 33 moves off of a lobe of the cam, whereby the arm 34 will close the switch 35. The motor 2! will then be energized independently of the vending machine to continue operation until the next lobe 2c is engaged with the roller 3% to lift the arm 34 and disengage the contacts of the switch 3!, breaking the circuit to the motor 25. There are the same number of lobes 29 on the cam 23 as there are pockets in the rotor and the lobes of the cam are positioned relative to the pockets 43 whereby when the motor 24 deenergized, one of the pockets will be "li nment with the discharge port it. Also rotation of the shaft It by the motor 2! prevents bridging of the cubes of sugar whereby said cubes will pass into the discharge chamber and over the upper face of the rotor into the pockets 23. Due to the vane 5-5 covering the discharge port E5, the thickness of the rotor, the slope of the upper urface of the rotor, and spacing between the rotor and the partition, no more than a desired number of cubes of sugar will become aligned with the discharge port I5, and the interengagement of the cubes on the upper surface of the rotor is such that additional cubes of sugar will not slide into the pocket it when the rotor is stationary. If the purchaser desires no sugar, the cubes remain undisturbed until the vending machine is again operated to obtain a cup of beverage, at which time the motor 2! is again energized to rotate the rotor and position the next pocket 53 in alignment with the discharge port l5, the cubes of sugar moving onto the vane 56 which has thin edges to facilitate such movement without damage of cubes. If the purchaser desires sugar he presses a manual switch 54 in a circult connecting the solenoid with the source of suitable current to energize said solenoid to move the slide and vane to effect registry of the discharge opening with the discharge port it and uncover said port. Simultaneously with such movement, the vane 58 enters the discharge chamber to engage and support the next cube of sugar in the pocket 43 above the one in the discharge port, which will drop through the discharge opening dS into a chute t5 and slide therethrough to drop in a cup of beverage. Upon release of the switch a spring will return the slide to move the vane 56 into covering relation with the discharge port it and the opening ts out of registry with the discharge port it and through engagement of the end of the slide and stop member 5? the vane 53 is also moved outwardly sufficiently to allow the next cube of sugar to drop onto the vane 56, If the purchaser desires a second cube of sugar he can again close the switch 54, energize the solenoid and repeat the process. Since only a desired number of cubes can be stacked in registry with a pocket 43, the purchaser will be limited to that number of cubes, although he can continue to operate the switch to energize the solenoid and efiect reciprocation of the slide.

It is believed obvious that we have provided a dispenser for cube sugar for positive and efiicient dispensing of a limited number of cubes into cups or other containers of beverage.
