United States Patent t) 3,1%,5519 VENEBENG MACEENE .lohn H. Schreiber, Chicago, ill., assigner to Chem-Met Corporation, Qhicago, ill., a corporation of illinois Filed May 7, i953, Ser. No. 278,534 Claims. (Cl. 1221-75) This invention relates to a vending machine and more particularly to an improved construction for a vending machine which is capable of dispensing large packets containing a plurality of containers or vessels.

Vending machines have attained a substantial acceptance in dispensing individual containers of liquids, such as, soft drinks. It has become readily apparent that it is desirable to vend a carrier of containers, that is, a holder having a plurality of bottles or cans contained therein. Carriers of soft drinks normally have six bottles in a carton. The vending of a six pack or a carrier of six by means of the customary vending machine presents numerous problems. A vending machine which is large enough to handle a six pack usually takes up so much space that the machine is not considered to be desirable in many locations. It is, therefore, a principal object of the present invention to provide a vending machine which vends carriers of merchandise and which machine is compact in its construction.

Another problem which is appurtenant of many vending machines is that the vending machines require electricity to drive various electric motors in the operation of the vending machine. These vending machines having electric motors present a considerable problem in view of the fact that many locations do not have a convenient source of electrical energy. Furthermore, the expense of the machine is substantially increased in view of the cost of the motors as well as the additional electrical insulating and testing which must be performed in order to have a safe machine. lt is, therefore, another object of the present invention to provide a vending machine which is entirely mechanically operated to make the machine safe and to eliminate the need of an outside power source.

it is a further object of the herein disclosed invention to provide a vending machine which is fool-proof.

It is a still further object of the instant invention to provide a vending machine which is economical to manufacture and has a high degree of reliability.

Other objects and uses of this invention will become readily aparent to those skilled in the art upon a perusal of the following specication in light of the accompanying drawings in which;

FIGURE 9 is another view of the same compartment show-n in FlGURE 8, but with a carrier in the upper portion of the compartment removed and a carrier in the lower portion of the compartment being shown in a partially raised position; and

FlGURE 10 is a view of the same compartment as in FIGURE 9, but showing the platform in a fully raised position and the carrier which ywas in the lower portion of the compartment being removed through the upper door.

Referring now to the drawings and especially to FIG URE l, a vending mach-ine generally indicated by numeral 2? is shown therein. The vending machine 20 generally consists or" a cabinet 22 which has a money operated control device or coin device 24 positioned in one corner of the cabinet. The cabinet 22 is divided up so that there are siX separate vertical compartments Z6 in the cabinet. These compartments are separated from each other by walls 28 and one of the compartments has the device 2d mounted therein. Each of the remaining compartments 2li has mounted therein an identical mechanism for dispensing merchandise. Each compartment has an opper door 30 hingedly connected to the cabinet for closing the upper portion lof the respective compartment. A lower door 32 is hingedly mounted on the cabinet within each of the compartments and a platform 34- mounted in each of the compartments below the respective lower door -for raising merchandise upward in the compartment. A platformy latch mechanism 36 holds the platform 3d in a down position. A door release mechanism selectively opens the upper and lower doors and =a door lock Irelease 38 holds the doors in an unlocked attitude.

Looking now to FlGURES 5 and 9, it may be seen that the upper door 39 is connected to wall 28 through a hinge dil. The door Sil has upstanding edges 42 around three sides of its periphery. Attached to one of the edges is an upper door lock rod d4 and an upper door operator rod lie. Both rods 4d and 46 are pivotally attached to the edge 42 by means of pins 48 and 5d, respectively. The door operator rod 46 is connected to the lower door 32 through an upper door control spring 52 in a manner which will be described in detail hereinafter.

The upper door lock rod 44 contains an elongated slot 54 which has a pin 56 `slideably mounted therein. The pin Se is fixed to a wall of the compartment, thus limiting the movement of the rod. It may be noted that the positioning of the rod d4 relative to the door and the pin S6 in relation to the length of the slot 5d is such that the maximum opening of the door Sil does not allow the door to open past a vertical position, thus, the maximum opening is such as that shown in FIGURE 10 so that the door automatically falls closed when released.

The rod 41thas a lock button 5S xed to one end for engagement with a locking means. The upper door is held in a closed position by an upper door lock bolt ed which engages the locking button 58 of the rod 44 The bolt is slideably mounted in the lower portion of the compartment. A spring o2 engages the bolt to urge constantly the bolt into engagement with the lock button. The bolt has a bolt pin ed iixed to the bottomV of the bolt.

A bell crank 6d is pivotally mounted on the bottom of the cabinet to operate the bolt. The bell crank engages the pin ed of the bolt. The bell crank has one arm cons nected to a cable 68 which cable is connected to a cable wheel for selectively rotating the shaft.

' has a pin 93 fixed therein, which pin 93 is positioned 1n 3 operator 70. The cable operator 7d is pivotally mounted on a rod 72. As may be seen in FIGURE 2, the cable operator has a lock lever 74 pivotally mounted thereon. The lock lever has a lock slot 76 which is engageable with a fixed latching wall 78. The cable operator has a dog 82 which is engageable with a roller 84. which is a part of a door control mechanism 86.

As may be clearly seen in FIGURE 2, the door control mechanism is mounted in cabinet 22 below coin device 24. Mechanism 86 includes a shaft 83 which is rotatably mounted in the cabinet, and a ratchet wheel SS is keyed to shaft 83 for rotation with the shaft. The roller 84, as are the other rollers, is mounted on a plate 87 which is also keyed to shaft 83. A pawl plate89 is rotatably mounted on shaft 83 and has a pawl 91 pivotally mounted thereon. The pawl 91 is engageable with the ratchet Pawl plate 89 a slot 95 of slide plate 97. A pair of plate pins 99 is fixed in the cabinet and each of the pins 99Yis mounted in a slot 101 in slide plate 97 to limit the motion of the slide plate to an up and down motion. An arm 103 is formed integral withl the slide plate, andthe arm 103 is attached to a spring'105 which holds the slide plate in an up position as shown in FIGURE 2. The slide plate has its upper portion connected to a portion of coin device 24 which selectively forces the slide plate 97 down against the force f spring 105 to rotate the plate 89 and the shaft 83.

A latch release 88 is pivotally mounted below the coin device 24 and engageable with the lock lever 74. The lock release is connected to a lock release handle 9d through a lock release rod 92; A lock release spring 94 holds the lock `release handle and the latch release in an up position as shown in FIGURE 2.

The lower door 32 is connected to wall 28 through a hinge 96. The hinge 96 has a spring 93 built therein to holdthe lower door in a partially open attitude whenthe door is unlocked. The lower door has a lower door lock rod 1190 pivotally connected thereto through a pin 102. The rod 19) Vhas an elongated slot 1114 with apinv 106 slideably mounted in the slot which pin is fixed to the same wall as pin S6. Y

As may be seen in FIGURE l0, the lower door may be opened past a vertical position so that it will remain in an opened attitude once the lower door is fully opened.

The rod 100 has a lower Vdoor lock button 10S fixed to its lower end to be engaged by a lower door bolt 110.

, The lower door bolt 110 is identical in construction to bolt. 6i) in that a spring 111 urges the bolt toward a closed position and the boltis connected to bell crank 112 which isidentical to bell crank 66. The bell crank 112 is, also,

CTL

The plate S7 has its outer periphery formed into a cam surface with alternating shallow indentations 131 and deep indentations 133. It may beV seen in FIGURE 2 Ithat when the follower is in a shallow indentation, the control rod is in a substantially vertical attitude; however, when the follower is in a deep indentation, the spring 127 .causes therod to rotate clockwise until the rod engages a stop rod 135 which is part of the coin device 24. 'y

In the operation of the instant device, the doors are held in an unlocked attitude by virtue of the lock levers 74 once merchandise has been removed. In servicing the instant vending machine, merchandise must be replaced. In order to replace merchandise, the upper door 3b is raised and held in an open position. VA first carton of bottles 124 is inserted in the compartment and placed on the platform 34. An operator pushes the platform down against the force of springs 116 until the platform is in its down position. With the platform all the way down, the dog 118 engages hook 120 so that the platform is then hooked and held in the down position. The lower door 32 is pivoted downward and a second carton of bottles 125 is loaded into the compartment. The second carton 126 is placed on top of the lower door, thus forcing the lower door down. The weight of the carton pushes the lower door into its lowermost or lock position. Since the lock levers have not yet been released from the latching wall 78, the lower door is unlocked and the weight of the second carton keeps the lower door in the down orV closed position. When the lower door is forced into its down position by the weight of the second carton, rod 100 is forced down into engagement with arm 122 to disengage' the hook 12d from dog 118 so that the platform 134 rises slightly until the tops of the bottles in carton 124 are in engagement with the lower door 32. Since the lower door is held down by the second carton, carton 124 is held in the. space between the lower door and the platform.

The upper door 30 is held in its Y.open position while the carton 126 is being positioned on top of the lower door. When the upper door is held in its open position, the rodV 416, which has an arm 128 of spring S2 pivotally attached thereto, moves -an engaging arm 130 of the same spring lback against the wall 28 of the compartment. The positioning of the carton 126 on the upper door provides a door opening means by the coaction of the carton with the arm 130 of spring V52. When the door is released by the operator, it may IbeY seen that the door partially closes to the attitude shown in- FIGURE 8. The coaction of connected to a cable 114 which cable 114 is connected to f.

an operating mechanism which is identical to latch operator 70. n

The platform 34 is constantly urged upward by a pair of extensiblek springs116 which are' mounted on opposite sides of the compartment and engage opposite edges of the platform. The platform has a platform dog 118 fixed to the bottom of the platform. A spring loaded Y platform hook 126 is engageable with the dog 11S. VThe hook 120 has an arm 122 which is engageable with the Y the spring with the carton or merchandise in the upper portion of the compartment holds the doo-r open. In

order to close the upper door, a force must be applied to the upper door, thus loading spring52. Each of the compartments is loaded in a similar manner. It may be seen that the energy source for the instant machine is bottom end of the lower doo-r lock rod llltl, so that when Y the lower door is closed, the lower door lock rod engages arm 122 todisengage the hook 120 from dog 118.

Associated with the door control mechanism is a reset' control 121 to provide a means for indicating that a Vlowerpdoor is the next door to open in the sequence of springsy mounted in the cabinet, so that an outside energy source is not required to operate the present device.- After all of the compartments are loaded, the doors .l must be locked. The coin device 24 must lirst be removed from the cabinet. VThecoin Vdevice is locked in' the cabinet by a conventional lock which is not shown in this instance. After the coin device is unlocked, it is `lifted out yof its compartment to reveal the lock release handle 90; Handle 9d is pushed down to p-ivot latch Vrelease 83, thereby engaging the lock leversY 74 to disengage the `lock levers from latching wall 78. When the lock levers are released, the springs 62 and'111 force the respective bolts 60 and 110 forward. Since the lower V doors are linztheir down or closed positions, the lower URE 2. The control rod 123 is connected to the door ,Y

controlmechanism through a follower 129 which is rotatably mounted on rod 123. Y

doors are locked by the coaction of bolts 11d-with the respective lower .door lock buttons 10d; However, the upper doors are in arpartially raised position. YA force is applied to. each upper door to close it. When each upper door is closed, the rod 44 is forced Vdown and each Y lock V'button 58 displaces its respective bolt 60 against the respective springV 62 so that the button passes the bolt and the bolt returns to its original position to lock the upper door in a closed attitude. The coin device may be then replaced.

It is evident that since the door control mechanism S6 operates sequentially, it is possi-ble that a lower door may be the next door to be opened after the cabinet is reiilled with merchandise. In order to prevent such an occurrence, the reset control i211 is provided. As was mentioned above, plate 87 has a series of alternating shallow and deep indentations El and 133, respectively. The shallow indentations are positioned on plate 87 in such a manner 4that they are cooperative 4with rollers which unlock upper doors and the deep indentatio-ns are cooperative with rollers which unlock lower doors.

The attitude of the instant device shown in FIGURE 2 is such that the next door to 'be opened is an upper door. It may be seen that follower 129 is in a shallow-indentation so that control rod 123 is in a substantially vertical attitude. It may be appreciated that with the control rod 123 in a substantially vertical attitude, the coin device may be positioned in its proper location in the cabinet. Thus, if the next door to Ibe opened is an upper door, the coin device may be replaced. It is also evident that if the follower 129 is in a deep indentation, spring 127 causes the control rod 123 to rotate clockwise into a position in engagement with stop rod 135 when the coin device is in the cabinet, and into a position occupied by stop rod 3.35 when the coin device is not in the cabinet. When the cabinet is refilled with merchandise and the coin device is lifted out, the control rod moves into its furthest clockwise position when the follower 129 is in a deep indentation. Should the next door to be opened in the sequence be a lower door, it is impossible to replace the coin device because the control rod engages the stop rod and prevents complete repositioning of the coin device. It is then necessary Vto adjust the door control mechanism so that the next door to be opened is an upper door.

In .order to obtain a carton of merchandise from the vending machine 2b, a suitable amount o money must be deposited in a slot 132 in the cabinet to activate the control device 2d. The operation of the c-ontrol device forces slide plate 97 down to rotate plate 89 which causes shaft 33 to rotate through the pawl and ratchet, thus roller 84 is moved counter-clockwise to engage dog 32 of cable operator 70. When the dog 34 moves forward, cable operator 7i) is pivoted about rod 72 to pull cable 68. As the cable operator 76 is pivoted, the lock lever 74 is moved back so that the latching wall 78 engages slot 76 to hold the operator 70 in a retracted position. The movement of cable 68 rotates the bel-i crank 66 about its pivot so that the bolt 6i) is retracted from engagement with the upper door lock button S8. The release of the door lock button 58 releases the upper door 30. Spring 52 which has been expanded by the closing of the upper door then may push the upper door open partially to the attitude shown in FlGURE 8. A purchaser then may complete raising of the door and lift out carton 126. It is evident that a purchaser may no-t obtain the merchandise .below the lower door 32 in view of the fact that the lower door remains locked. Once the merchandise is removed and the upper door is released, the door does -fall down to a completely closed attitude since the engaging arm 13% of spring 152 has no merchandise which it may engage. Thus, the upper door is completely closed.

When additional monies are deposited, -the door control mechanism 85 operates again to pull cable 114 to rotate bell crank 112, thereby disengaging bolt 1l@ from the lower door lock button 198. Once the door lock is disengaged, sp-ring 9S in the lower door immediately pops the lower door up partially and the springs llo raise the platform 34 so that the merchandise, that is, carton 124, pushes the lower door to a completely open attitude, As the platform is raising the merchandise upward, the lower door is movi-ng to an open position so that it engages the engaging arm i3@ of the spring :'52, thereby raising the upper door 3l) to a partially open attitude. The rmerchandise contained on the platform then assumes substantially the same respective position as the merchandise which was positioned on the lower door. The purchaser then may raise the upper door to a completely open attitude and lift the carton 124 from the platform 130. Upon removal of the merchandise the upper door falls to its closed attitude and movement of the upper door to a closed attitude pushes the lower door to a partially closed attitude though the spring 9d keeps the lower door partially opened.

lIt is evident that when additional monies are deposited in slot 132, the door control mechanism 36 releases the upper door of the next compartment in the sequence which compartment has an identical mechanism to the mechanism described above as does each other compartment.

From the foregoing descrip-tion, the construction and operation of the instant vending machine is evident to those skilled in the art.
