REFRIGERATED PACKAGE VENDING MACHINE Filed Nov. 18, 1950 v 4 Sheets-Sheet 3 INVEN TOR. ff/R/S 77 4 6452/1-2 $5M United States Patent REFRIGERATED PACKAGE VENDING MACHINE Christian Gabrielsen, Whippany, N.

Manufacturing Co., Inc., ration of New York 1., assignor to Rowe Whippany, N. J., a corpo- My invention relates to a refrigerated package vending machine for merchandising containers of milk, chocolate milk, carbonated beverages, or the like. The refrigerated package vending machines of the prior art have had limited capacity and are adapted to vend a limited variety of containers of potable refrigerated drinks. Furthermore, the machines of the prior art have been complicated in structure, have had a limited capacity and are expensive to construct.

One object of my invention is to provide a refrigerated package vending machine for vending containers of milk, chocolate milk, orange juice, carbonated beverages and the like, in which a plurality of different types of packaged drinks may be merchandised from a single machine.

Another object of my invention is to provide a refrigerated package vending machine of increased capacity.

Another object of my invention is to provide a merchandising machine for refrigerated drinks and packages in which the simple pressing of a button automatically makes the selection.

Another object of my invention is to provide a merchandising machine for refrigerated containers of drinks in which a common prime mover is arranged to dispense articles from a row in a predetermined order.

Another object of my invention is to provide a merchandising machine for refrigerated packages in which the dispensing row is automatically replenished when the last container from the row has been dispensed.

Other and further objects of my invention will appear from the following description.

In the accompanying drawings which form part of the instant specification and which are to be read in conjunction therewith, and in which like reference numerals are used to indicate like parts in the various views:

Figure l is a perspective view of a refrigerated package vending machine containing one embodiment of my invention with the door of the cabinet open showing the arrangement of the storage and dispensing shelves of the respective levels in which three different types of refrigerated packages are adapted to be stored and vended.

Figure 2 is a side elevation of one of the vending levels of the machine shown in Figure 1.

Figure 3 is a sectional view taken along the line 33 of Figure 2, with parts broken away.

Figure 4 is a perspective view of the mechanism for operating the dispensing members.

Figure 5 is a diagrammatic view showing the electrical circuit involved for controlling the dispensing operating motor.

Figure 6 is a diagrammatic view showing the circuit involved for controlling the motor drive for the replenishing system which moves a row of packages from the storage shelf to vending position.

In general, my invention contemplates the provision of a refrigerated cabinet provided with the usual refrigerating equipment of any desired type known to the art. A plurality of shelves are supported within the cabinet in any suitable manner. The construction is such that one Patented Oct. 4, 1955 end of each of the shelves is supported from the cabinet Wall. The other end of the upper shelf is supported from the roof of the cabinet. The other end of the second shelf is supported from the first shelf, and the other end of the third shelf is supported from the second shelf. A series of baflies is provided to deliver the merchandise dispensed to a bucket door giving access to the interior of the cabinet and maintaining it sealed to reduce loss of refrigeration through the heat of the outside atmosphere upon the opening of the door to remove a dispensed package. Each of the shelves comprises a row of trap doors each adapted to support one of the packages to be dispensed adjacent a storage shelf. The trap doors are adapted to be sprung in succession in response to the deposit of coins in a coin register and the actuation of an appropriate push button. When all of the packages from the trap doors have been dispensed, automatic means are provided for pushing a fresh row of refrigerated packages from the storage shelf to the trap doors. Each of the shelves is provided with its own prime mover for operating the trap doors and for operating the pushing arrangement for pushing packages from the storage shelf to the trap doors.

More particularly, referring now to Figure 1, a cabinet 10 may be of any suitable construction provided with heat insulated walls, top, bottom and sides. Suitable refrigeration machinery is provided in casing 12 below the floor 14 of the refrigerated area and serves to maintain the interior of the cabinet at a reduced temperature An inner door 16 which is insulated is adapted to be swung into position and secured by latches 18 and 20 to completely seal the refrigerated area except for an opening 22 formed in the door 16. The opening 22 is normally closed by the portion 24 of a pivoted door having a lower portion 26 which is normally horizontal and adapted to register with the lower delivery chute 29 on which the delivered package 31 passes onits way to a customer. As the door 24 is swung outwardly and downwardly, the portion 26 will move upwardly to close the opening 22 and at the same time make the delivered package accessible to the customer. The length of the horizontal portion 26 is longer and heavier than the portion 24 so that the bucket door 28 as a Whole will tend to pivot by gravity to the position shown in Figure 1. An outer door 30 seals the inner door 16. The outside of the inner cabinet carries a switch housing 33 carrying push buttons 34, 36 and 38 adapted to control the dispensing motor for the respective levels. The outer door 30 is formed with an opening 40 adapted to give access to the push buttons. An empty signal light 42 is carried by the housing 33 and is visible through the opening 44 in the outer door 30. A coin insert opening 46in the outer door permits coins to fall to the'coin guide 48 which passes to an electrical coin register. A container 50 is formed in the door 30 adapted to receive returned coins from the coin register either in event that spurious coins are rejected by the slug ejector forming part of the coin register, or in event one of the vending levels is empty and a purchaser does not desire from the other levels.

The left side wall of the interior of casing 10 carries three angle irons 52, 54 and 56 secured to the interior wall. The upper vending level assembly 58 has its lefthand end supported by the angle iron 52. A suspension member 60 is secured to the right-hand side of the upper vending level assembly 58 at its lower end and removably secured to a bracket 62 at its other end. The bracket 62 is supported from the roof 64 of the cabinet 10. A bafile 66 is secured to the side wall of the interior of the cabinet and is adapted to guide packages from the upper level onto a second baffle 68 carried by the interior of the cabinet from whence the packages fall to the demerchandise being vended livery guideway 29; The distance between the upper level'and'the baffle 66', the distance between the bafile 66- and the baflie 68, and the: distance between the bafiie 68 and the delivery chute 29 is such that the package is not permitted to-fall free through a distance sufiiciently great to rupture the package or cause it to leak. This is especially important for milk which is usually vended in water-proof'ed cardboard containers. The second vending l'evel assembly 70 has its left-hand end supported by the angle iron 54 and its right-hand end supported by member 72 and a bracket 74 carried. by the under side of the first vending level assembly 58'. Similarly, the third level vending assembly 76 has its left hand end supported by the angle iron 56 and its right-hand end supported by member 78, the upper end' of which isremovably held" by a bracket 80 secured to the lower side of the second vending level assembly 70. Each of the vending level assemblies is a unit in and of itself and they are identical in construction with the exception that the upper vending level assembly 58' is longer than the second. vending level assembly which must be shortened to provide space for the bafll'e 66. Similarly, the third vending level assembly 76 is somewhat shorter than the second vending level assembly 70 to provide space for the bathe 68. The faster selling item may be placed on the uppermost level, while the least popular may be placed on the lowest level. It is to be understood, of course, that While I have shown. three levels, a number of additional levels may be used if desired. Furthermore, the dimensions of the cabinet may be such that each of the vending levels may be made longer. In this manner a maximum capacity of packages can be assembled within a single refrigerated cabinet, thus making my machine very flexible.

Referring now to Figures 2 and 3', in which one of the vending level assemblies is shown, it is seen that it comprises a frame 80 formed with an upper smooth supporting surface 82 terminating adjacent a plurality of trap doors 84, each of which supports a. package 86 in dispensing position. The packages 88 are supported by the storage shelf 82 which is provided with a plurality of longitudinally extending upright guidemembers 90.- The distance between guide members is slightly greater than the width of the packages 88 which are supported by the storage shelf. The guide members extend only over the storage shelf and their function is. to keep the packages aligned with the trap doors 84 while they are being pushed from the storage shelf. 82 onto-the trap doors. The frame carries a shaft 92 rotatably mounted in suitable bearings at each side of the right-hand side of the frame 80 and a second shaft 94parallel tothe shaft 92 adjacent the left-hand side of the frame, as viewed in Figure 3. The shaft 92 carries a pair of gears 96 and 98 secured to the ends of the shaft 92 for rotation, therewith. The shaft 94 carries a similar pair of gears 100 and 102 and'a third gear 104. Carried by the frame by means of supportingmemher 106, I' provide an electric motor 108 adapted to drive a reduction gear assembly within housing 110'to rotate a shaft 112 to which is secured a gear 114 for rotation therewith. A sprocket chain 116 extends between the driving gear 114 and driven gear 104. The. arrangement is such that the motor 108' will rotate the shaft 94; and gears 100 and 102. Extending between gears 100 and 96 I provide a sprocket chain 118. Extending between gears 102 and 98 I provide a second sprocket chain 120. A pusher member 122 is secured to the chains 118 and. 120 by means of securing members124 and. 126. The pusher member is adapted to contact the rearrnost row: of packages 88 so as the motor drives in a direction to move the pusher to the right, allof the packages on the shelf 82 in front of the pusher will move to the right. A pivoted switch actuating member is mountedon suitable supports 132 carried by the frame 80. When all the packages of the row supported by trap doors 84 have, been dispensed, a spring normally urges the member 130 to the dotted line position shown in Figure 2. In this position, the pivoted switch acutating member 130' is adapted to actuate a switch 134 to close the circuit to the motor 108 adapted to actuate the pusher. When the row of packages 86 is moved to position upon the trap doors 84, the pivoted plate 130 will be rotated in a counterclockwise direction, as viewed in Figure 2, to the position it occupies in Figure 3-, that is, to=a substantiallyvertical position. When it reachesthisposition, the switch 134 will act to interrupt the circuit to. the motor 108. The lower side of sprocket chain: 120 carriesa lug which moves to the left, as viewed in Figure 2, as the pusher 122moves to the right. When the last row of packages 88,. that is the row in contact with the pusher 122, is pushed onto the trap doors 84, the lug 140 will be: close to a switch arm 142. When the last package has been vended, the pivoted plate 130 will operate switch 134 causing motor 108 to run and the sprocket chain will carry lug140 into contact with the switch arm 142 to interrupt the circuit through motor 108 so that the switch 134 operated by pivoted member 130 will no longer be effective to close this circuit. This prevents a continual running of the motor 108 and the jamming of the pusher member 122 against the upright members 132. The switch arm 142 is also adapted to break the circuit; of motor 174, as can be seen by reference to Figure 5. This precludes operation of motor 174 by push: button 34 when there is no merchandise on the trap doors for deliveryto acustomer. A pushbutton 143 is adapted to reverse the direction of operation of the motor 108, as will be explained more fully hereinafter, to move the pusher 122 to the left so that fresh, packages may be loaded onto the storage shelf. This push buttonis accessible only when the inner door 16 has been opened.

Thus far we have seen how refrigerated packages are moved from. the storage-shelf to the dispensing trap doors 84. Let us now consider the operation of the dispensing assembly. This can best be seen by reference to Figure 4. The frame 80 carries a pair of brackets on which is rotatably mounted a shaft152. Each of the trap doors 84 is pivotedby means of a pair of hinges 1-54' to a flange 156 formed integral with theend. of the storage shelf82. Mounted on flanges I56 and 158 through suitable openings formed therein I provide a plurality of trap door supporting members 160; Each of these members is urged tothe right by means of springs 1'62 so that the right-hand portion of the supporting members 160 project underneath. the trap doors 84', preventing them from pivoting downwardly to dump the' packages supported thereby; The shaft 152 carries a star wheel 164 secured thereto for rotation therewith. The star wheel is adapted tocoact with a crank 166 carried by a rotatable cam 168 secured to shaft 170- of a reducing gear train lodged within the casing 172 and adapted to be driven by a motor contained within casing 174. The motor is controlled by a switch 176 actuated by an arm 178; When the toe 180 of the arm 178' is in the re-entrant portion 182 of the cam 168; the motor circuit is normally broken. When the motor circuit is completed by pressing, one of the selector buttons, as will be pointed out more fully hereinafter, it starts to rotate in the direction of the arrow, lifting the toe 180 out of the re-entrant portion 182, maintaining, the switch 176' in closed position. by means of arm 178, permitting. the motor to run until the cam 168 completes one revolution. In completing one revolution, the crank pin 166 will rotate the star wheel through a fractional part of a complete revolution. The arrangement is such that the number of fractional parts depends on the number of trap'doors to be operated by the common. drive. The shaft 152 carries a plurality of cams 184 secured thereto for rotation therewith. Each of these cams is displaced froman adjacent cam by an angle. representing the angle of rotation. of the star, wheel during one revolutionv of; the crank pin166. In; Figure 4,

during the last operation of the motor 174, cam 184' pulled the supporting member 160 rearwardly against the action of spring 162 by means of the portion 161' and permitted trap door 84 to drop its merchandise. As soon as the rotation proceeded far enough to permit the portion 161' to slip by the toe of-cam 184', the spring 162' forced the member 160 to the right, re-erecting the trap door 84'. The toe of cam 184a is just about ready to contact the portion 161aof the member 160a in order to pull it against the action of spring 162a clear of the trap door 84a so that this trap door may pivot downwardly. The phasing is such that each trap door will drop in succession until the last package has been released. When this occurs the pivotedmember 130 will operate the switch to replenish the merchandise to the trap doors so that the motor 174 can again operate successively to dump the trap doors in succession by means of the arrangement just described.

The replenishment of the trap doors takes place by successive operations of motor 108 underthe control of switch 134. As pointed out above, when the last row of packages 88 is pushed on the trap doors the lug 140 is adjacent the switch arm 142. When the last package is dumped, the plate 130 causes the motor 108 to run carrying the lug 140 in contact with the switch arm 142 and breaking both the circuit through the pusher motor 108 and the dispensing motor 174.

The circuits involved can be seen by reference to Figures and 6. When coins are placed in the coin register 32, the pressing of selector button 34 completes a circuit from the positive terminal 200 through conductor 201, through the electrical coin register 32 in which the circuit is completed by proper coins, through the conductor 203, through push button 34, through conductor 202, through normally closed interrupter switch 142, through conductor 205, to conductor 206 and thence through the armature of motor 174 and the field winding 208 of the motor in parallel to ground 210. The push button 36 controls a circuit through another motor similar to motor 174 for another level through a separate conductor 211. The push button 38 controls an arrangement similar to that shown as controlled by push button 34 for a third level energized through conductor 214. Each level has its own dispensing motor 174 and its own cam 168 as well as its own cam-operated switch 176 and its own normally closed interrupter switch 142..

As soon as the motor 174 begins to rotate through the energization completed by the push button and the coin register, the shaft 170 will rotate, carrying its cam 168 around and closing the switch 176 by means of the arm 180 moving out of the cam recess 182. '-When the push button is released the motor will continue to run, current flowing from positive terminal 200' through conductor 204 through the cam-operated switch 176 to conductor 206. When the motor has completed one revolution and the recess 182 is adjacent the brush 180 the switch will open and stop the motor and it can bestarted only by deposit of coin and the pressing of the push button 34.

All three levels are controlled from a singlecoin register placed in series with the three push buttons which are arranged in parallel. Any suitable interlocking arrangement known to the art may be provided toprevent the operation of two push buttons simultaneously.

Each pusher motor 108 is controlled by a normally open switch 134. When the pivoted plate 130 operates to close the switch 134, current will flow from the positive terminal 300 through normally closed interrupter switch 142, through the switch 134, through conductor 302, through conductor 304, through the armature of motor 108 to ground 306. The field current will flow through conductor- 308, through field winding 310, through conductor 312, through armature 314, through conductor 316 to ground 306, causing the motor 108 to run in a direction to feed packages from the storage shelf to the trap doors. After the last package is dispensed,

the pivoted member will close the switch 134 causing the motor to run through a very short distance. The arrangement is such that the lug will open interrupter switch 142 stopping the motor 108. -To return the pusher member 122 to the left, as'viewed in Figure 3, the button 143 is pressed. When this occurs, current will flow from the positive terminal 300 through conductor 320, through armature 322, which now bridges contacts 324 and 326, thence through conductor 328, through conductor 330, through the fieldwinding 332, which is wound oppositely from the field winding 310, to contact point 334, across armature 314, to contact point 336, through conductor 338,to ground 306." At the same time, current will flow through conductor 304, through the armature of motor 108 to ground 306. Since the field current is reversed with respect to the armature current, the motor 108 will run in the opposite direction from feeding packages to the trap doors, returning the pusher member 122 to the left. package is placed on the trap door to prevent the pivoted plate 130 from closing the switch 134 to prevent pusher 122 from immediately being returned to the right after button 143 has been released.

"It will be seen that I have accomplished the objects of my invention.
