1 @lairn. (Cl. 221-124) My invention relates to a cigarette merchandising machine and more particularly to a multicolumnar console cigarette merchandising machine for selectively dispensing a large number of diiferent types and brands of cigarettes.

With the large number of different types and various brands of cigarettes currently on the market, a cigarette merchandising machine must provide a large selection if it is to meet an appreciable portion of the market demand. Cigarette merchandising machines of the prior art may be arranged to provide a wide selection by increasing the number of dispensing units or sections in the machine. These multiple selection machines of the prior art are, however, excessively wide and, consequently, are not suitable for installation in many desirable locations owing to the large floor area occupied by them. Moreover, the difference in demand for the various types and brands of cigarettes is not accounted for in multiple section machines of the prior art since each section o'r unit has the same capacity. If the units containing less popular brands are loaded to capacity, the supplies of the more popular types or brands of cigarettes become exhausted before the supplies of the less popular brands. As a result, the machine has irregular service requirements. Less popular brands left in the machine may become stale. If the units containing less popular brands are not loaded to capacity much of the machine cabinet space is Wasted.

I have invented a multicolumnar console cigarette merchandising machine for dispensing a large number of different types and various brands of cigarettes. My machine is compact and of a size which permits its installation in most desirable sales locations. The design of my machine tends to ensure that the supplies of less popular brands or kinds of cigarettes are exhausted at substantially the same time as are the supplies of the more popular kinds and brands of cigarettes. My machine makes eflicient use of the available cabinet space.

One object of my invention is to provide a multicolumnar console cigarette merchandising machine for dispensing a large number of different types and various brands of cigarettes.

Another object of my invention is to provide a multicolumnar console cigarette merchandising machine which is compact, occupies a small floor space and is of a size which permits its installation inmost desirable sales locations.

A further object of my invention is to provide a multicolumnar co'nsole cigarette merchandising machine of such flexible design and construction that the supplies of less popular kinds and brands of cigarettes are exhausted at substantially the same time as the supplies of the more popular kinds and brands of cigarettes if properly loaded.

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

In general, my invention contemplates the provision of a merchandising machine including a plurality of first supply columns disposed adjacent the front of the machine cabinet. The respective first columns, together with associated auxiliary columns, contain supplies of the more popular brands of cigarettes. I arrange a plurality of second supply columns behind the respective first supply columns for housing relatively smaller supplies of the less popular brands of cigarettes. Respective dispensing means responsive to the operation of the selection means are provided for the respective first and second supply columns. Means responsive to the operation of a dispensing means prevents a dispensed package of cigarettes from being delivered to a customer until coins deposited in the machine have been accepted by the coin mechanism. I provide my machine with means for ensuring that any dispensing member, which may have become accidentally stuck during the dispensing operation, returns to its inoperative position when the machine cover is opened. This construction prevents bending of the stuck member during the loading operation in such event.

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 1 is a fragmentary sectional view of my multicolumnar console cigarette merchandising machine.

Figure 6 is a perspective view of one of the empty locks of my multicolurnnar console cigarette merchandising machine.

Figure 7 is a fragmentary perspective view of part of one of the selecting means of my multicolumnar console cigarette merchandising machine.

Figure 8 is a fragmentary side elevation of a portion of the dispensing mechanism of my m'ulticolumnar console cigarette merchandising machine.

More particularly referring now to Figures 1 to 3 of the drawings, my multicolumnar console cigarette merchandising machine is housed in a cabinet having a back 10 and a top 12. The front or cover '18 of my machine cabinet opens to permit loading of the columnar cigarette containers to be described hereinafter. The mechanism is supported in'the cabinet by a frame including side members 14 and 16.

As can be seen in Figure 3, side frame 14 carries a hinge 20 to which I secure by any means, such as welding or the like, a container support plate 22. At spaced locations along the length of plate 22, I mount a plurality of partitions 24 extending toward the back 10 of the machine. I fix a bar 26 to the rear edges of partitions 24 adjacent the bottoms thereof.

It will be seen that each pair of adjacent partitions 24 defines a section of my merchandising machine. I divide each of these sections into a pair of columnar containers by mounting a shift column, indicated generally by the reference character 28, in each of the sections. Each shift container 28 includes a back 30 and a side 32. A lip 34 formed at the top of the back 30 of each of the shift containers 28 suspends the container from the plate 22. A bracket 36 fixed to plate 22 by a screw or the like 38 retains each of the lips 34 on the plate 22. Each column 28 forms one of the columnar containers of a section formed by a pair of adjacent partitions 24. The space in each section behind the shift column 28 forms the second columnar container, indicated generally by the reference character 40, of the section. In order to retain packages of cigarettes within the container 40, I form laterally extending lips 42 on the rear edge of each of the partitions 24. Springs 44 fixed by any convenient means to the plate 22 normally urge the respective shift containers 28 to pivot in a counterclockwise direction as viewed in Figure 1 about the upper edge of plate 22 to the broken line position shown in Figure 1. It will be understood that each spring 44 is of sufficient length and has a sufiiciently long throw to move the associated wall 30 from the full line position shown in Figure 1 to the broken line position. Packages of cigarettes normally disposed in the container 40 engage lips 33 on sides 32 to hold the shift column 28 of a section in the full line position shown in Figure 1 against the action of spring 44 until the supply of packages reaches a predetermined -low level, as will be explained in detail hereinafter. Slotted platforms 46 carried by partitions 24 below the containers 40 support the columns of packages of cigarettes disposed in the containers 40. Brackets 48 supported by any convenient means between adjacent partitions 24 below the respective shift columns 28 support the packages of cigarettes disposed in columns 28 before the columns shift.

A mounting bracket 50 fixed to back by rivets 52 carries the backs 54 by any convenient means, such as welding or the like, of a plurality of rear columnar containers, each of which is indicated generally by the reference character 56. Pairs of sides 58 complete the respective containers 56. Lips 60 formed along the forward edges of the sides 58 retain packages of cigarrettes within the containers 56. Slotted platforms 62 welded to a bracket 64 fixed to plate 54 by rivets 66 support the packages of cigarettes in the rear containers 56. As can be seen by reference to Figure 3, the rear columnar containers 56 are staggered with respect to containers 40 and the shift columns 28. Containers 40 and the associated shift columns 28 contain the respective more popular brands of cigarettes while the rear containers 56 may contain less popular brands. Since the supply of packages of cigarettes in a container 40 and an associated shift column 28 is greater than the supply contained in a rear column 56 which has no reserve supply in the form of a shift column, the supplies of the more popular kinds or brands of cigarettes will tend generally to become depleted at somewhat the same time, in many cases, as the supplies of the less popular brands or kinds of cigarettes.

My merchandising machine includes a plurality of respective selecting pull rods 68 slidably mounted in a bracket 70 carried by the top 12. Each of the pull rods 68 is associated either with a front container 40 and a shift column 28 or with a rear container 56. Alternate pull rods 68 along the width of the machine are associated, respectively, with a front container 40 and with a rear container 56. Respective flexible tapes 72 connect the selecting pull rods 68 to a plurality of respective links 74. As can be seen by reference to Figures 1 and 7, each link 74 includes a lateral extension 76 which pivotally connects the link with an operating bar drive link 78 and a dispenser drive link 80. A pin 82 pivotally connects the drive link 80 associated with a link 74 corresponding to a container 40 to the arcuate ejector 84 of a dispenser 86 pivotally mounted on shaft 88 extending between the sides 14 and 16 of the machine. Respective pins 90 connect each of the drive links 80' associated with the rear containers 56 to one arm 92 of a dispenser 94 associated with a rear container 56 of the machine. A shaft 96 supported between the sides 14 and 16 pivotally mounts the dispensers 94 associated with the rear column.

Each of the operating bar drive links 78 is housed by a housing 98 extending between the sides 14 and 16 of the machine. Each of the links 78 carries a latch 100 by means of a pin 102. When one of the pull bars 68 is operated to move the associated link 78 upwardly as viewed in Figure 1, a portion 104 of housing 98 pivots latch 100 into engagement with the operating bar 106 of the machine to provide a return for the operating bar 106 as the operating mechanism of the machine returns under the influence of gravity when the pull rod 68 is released. Slots 108 in the side frames 14 and 16 mount operating bar 106 for vertical movement. Toothed segments 110 carried by the operating bar 106 engage racks 112 as the operating bar moves to provide parallel motion for the bar. Each time a pull bar 68 is actuated it pulls the associated link 78 upwardly as viewed in Figure l. A toe 79 on the link 78 is disposed under bar 106 and is guided in a slot 81 in the front wall of housing 98. Thus, if link 78 moves upwardly it pulls the operating bar upwardly. The segments 110 on the ends of the bar ride along the racks 112 to cause the bar 106 to move parallel to itself no matter which link 78 across the machine is actuated.

As can be seen by reference to Figures 2 and 5, a pin 114 pivotally mounts a rack 116 on the outboard surface of side 16. A second pin 118 carried by side 16 rides in a slot 120 formed in the bottom of rack 116. A pin 122 pivotally mounts a lever 124 on side 16. A link 126 forming part of the locking mechanism for the door 18 carries a pin 128 which engages lever 124 to position a lateral extension 130 on lever 124 to position rack 116 to permit it to be engaged by a ratchet 132 carried by the operating bar 106. The underside of the lever 124 rests on the pin 128 carried by link 126. The engagement of ratchet 132 with the teeth of rack 116 prevents a customer from changing his mind after he has initiated a dispensing operation and constrains the customer to complete the vending cycle. When the cover 18 is unlocked, link 126 moves upwardly to pivot lever 124 to move extension 130 out of engagement with rack 116. This permits rack 116 to move out of engagement with ratchet 132 to permit the operating bar and the selecting and dispensing mechanisms to return to their normal positions under the influence of gravity before the cover is removed. This feature of my invention prevents damage to a dispenser which may have become stuck in a supply container.

Referring now to Figures 1 to 3, all the tapes 72 pass over a roller 134 formed of a material such as bronze or the like. A plate 136 fixed on a shaft 138 for rotation therewith mounts roller 134 in appropriate bearings. I rotatably mount shaft 138 in the sides 14 and 16 of the machine. Respective springs 140 and 142 normally bias cranks 144 and 146 fixed on the ends of shaft 138 for rotation therewith to rotate in a clockwise direction as viewed in Figures 1 and 2. These springs bias roller 134 to the full line position shown in Figure 1. If for any reason the dispensing mechanism of any section of the machine becomes jammed, springs 140 and 142 permit yielding of roller 134 when a pull rod 68 is operated by a customer. This action prevents injury to the machine parts.

When a customer operates a pull rod 68 corresponding to a kind of merchandise carried in container 40, the associated dispenser 86 pivots about shaft 88 in a counterclockwise direction as viewed in Figure 1 and the ejector head 84 enters the column 40 through a suitable opening 148 formed in bar 26 and platform 46. Head 84 pushes the lowest package of cigarettes in the container 40 out of the container. As can best be seen by reference to Figures 2 and 8, the operating bar 106 carries a link 150 adjacent side 16. A pin 152 connects link 150 to a cam 154 pivotally carried by a pin 156 on side 16. When the operating bar moves upward during a dispensing operation, cam 154 pivots in a clockwise direction as viewed in Figure 8 to engage a link 158 suspended from a pair of cranks 160 and 162 by respective pins 164 and 166. Cranks 1'60 and 162 are mounted for rotation therewith on respective shafts 168 and 170 rotatably mounted in the side frames 14 and 16 of the machine. Shaft 170 carries for rotation with it a platform 172. When the ejector head 84 pushes the lowermost package of cigarettes out of the container 40, operating bar 106 moves upward to position platform 172 to receive the package. After the money deposited in the machine has been accepted, operating bar 106 moves downwardly and platform 172 returns under the influence of gravity to the full line position shown in Figure 1 to drop the package of cigarettes supported thereby. Guides 174 and 176 extending between the sides 14 and 16 direct the released package to the machine dispensing tray formed by members 178 and 180 carried by the cover 18. A bracket 182 supported by bracket 48 ensures that a package supported on platform 172 drops toward guide 176 when platform 172 returns to its initial position.

Referring now to Figures 1 and 4, bracket 182 is formed with a plurality of slots 184 along its length corresponding in number to the number of shift columns 28. Respective brackets 186 support a plurality of shift column restraining rod actuating arms 188 by means of pins 190. Each of the arms 188 pivotally carries a rod 192 on a pin 194. It will be appreciated that as the lowermost package of cigarettes in container 40 is forced out of the container by head 84 of ejector 86 it engages arm 188 to pivot the arm in a clockwise direction as viewed in Figures 1 and 4 to push the associated rod 192 through the opening 184. If the containers 28 and 40 contain packages of king size cigarettes, the forwardly moving rod 192 engages a first projection 196 carried by the back 30 of the corresponding shift column. Each projection 196 extends through a slot 198 in a bracket 48. The engagement of rod 192 with projection 196 counteracts the pressure of spring 44 tending to force the shift column 28 to the broken line position shown in Figure 1. This action prevents the column 28 from interfering with the downward movement of the packages of cigarettes in container 40 during a dispensing operation. After the dispensing operation is complete, rod 192 returns under the influence of gravity to the full line position shown in Figures 1 and 4 to permit the shift column 28 to operate, provided that the supply of packages in container 40 is below a predetermined level. It is to be understood that the slots 198 permit the columns 28 to shift without interference between a bracket 48 and a projection 196. If containers 28 and 40 contain a supply of regular size packages, shift column 28 normally will occupy such a position that projection 196 will be out of the path of movement of rod 192. In order to provide a means for relieving the pressure of spring 44 on the shift column in this case, I fix a second projection 200 to the back 30 of the shift column. With a supply of regular cigarettes in the column and the associated container 40, this projection 200 will be engaged by rod 192 during a dispensing operation. The arrangement is such that when a front container 40 is filled with king size cigarettes, these packages act against spring 44 to hold the associated shift container in a position at which projection 196 is in the path of movement of rod 192. When regular size cigarettes are in a container 40, the shift container 28 moves in a counterclockwise direction from the position it occupies with king size cigarettes in the container 40 to a second position at which the shift container is held against the action of spring 44 by the regular size cigarette packages. As the container 28 moves, the extremities of projections 196 and 200 follow arcuate paths. As the shift container moves from its king size position to its regular size position, projection 196 moves along its arcuate path to a position out of the path of bar 192. At

the same time a projection 196 moves along its arcuate path to a position in the path of bar 192.

When a pull bar 68 corresponding to a rear container 56 is operated, the corresponding dispenser 94 pivots in a counterclockwise direction as viewed in Figure 1. Each of the dispensers 94 carries a pin 202 which pivotally mounts a finger 204. A spring 206 extending between ejector finger 204 and the dispenser 94 normally biases the finger for movement in a clockwise direction as viewed in Figure 1. A stop 208 on finger 20'4 limits the pivotal movement of the finger under the influence of spring 286. When a dispenser 94 pivots in a counterclockwise direction on shaft 96, finger 204 enters into the corresponding rear container 56 through an opening 216 to push the lowermost package of cigarettes out of the column. As dispenser 94 pivots to push a package of cigarettes out of container 56, operating bar 106 moves upwardly as viewed in Figure 8 and cam 154 pushes link 1558 to pivot crank and shaft 168 in a counterclockwise direction. Shaft 168 carries for rotation therewith a platform 210. When cam 154 pivots crank 160 as the operating bar 106 moves up, platform 210 pivots to support the package of cigarettes pushed out of container 56 by finger 204. After the money has been accepted by the coin mechanism and the operating bar returns, platform 210 returns to the full line position shown in Figure 1 to permit the package of cigarettes to fall to the guide 176.

Referring now to Figure 6, I provide each of the containers 56 with an empty lock 212 for closing the opening 216 through which a finger 204 passes in pushing a package of cigarettes out of container 56. Identical locks 212 close the openings 148 through which dispensers 84 pass in pushing packages of cigarettes out of containers 40. I pivot each empty lock 212 associated with a container 56 on a pin 214 carried by back 54. Each pin 214 mounts its empty lock 212 adjacent the opening 216 in back 54 through which a finger 204 passes in performing a dispensing operation. Each lock 212 is formed with a laterally extending projection 218 on which the lowermost package of cigarettes in a container 56 normally rests. The weight of the supply of packages of cigarettes in the container 56 acts on extension 218 to position lock 212 so that a slot 220 formed in the lock registers with the opening 216 to permit entry of finger 204 into the container 56. When the supply of packages in a container 56 is exhausted, the associated lock 212 pivots under the influence of gravity to a position at which it blocks opening 216 to prevent the entry of finger 204 into the container. Each of the containers 40 is provided with an empty lock 212 for closing its opening 148 when the supply of packages of cigarettes in the respective column is exhausted. The locks 212 associated with containers 40 are mounted in the same manner as those locks associated with containers 56.

As can be seen by reference to Figures 2 and 8, operating bar 106 pivotally supports an antitilt locking link 222 which passes through a slotted bracket 224 fixed on side 16 by means such as rivets 226 or the like. I form link 222 with teeth 228. It normally rests under the influence of gravity in a position where its teeth 228 do not engage a side of the slot in bracket 224. Thus the link normally permits movement of the operating bar 106 after it has been freed by the deposit of coins in the machine. If an attempt is made to return the customers money before acceptance by tilting the machine while moving operating bar 106, link 222 pivots to a position at which one of its teeth 228 engages the edge of the slot in bracket 224 to prevent movement of operating bar 106 until the machine is returned to upright position. In this position. the money will be deposited in the coin box of the machine.

As can best be seen by reference to Figure 2, operating bar 106 also carries a link 230 pivotally connected by a pin 232 to a drive link 234 for the match dispensing drive mechanism, indicated generally by the reference character 236. Any appropriate match dispensing mechanism can be employed and it is accordingly not shown.

My machine includes, as can be seen by reference to Figure 3, a coin register mechanism 238 carried by side 16 for receiving coins deposited in a coin slot 240. Reg ister 238 may be of any type known to the art which frees operating bar 106 in response to the deposit in the machine of a sum in coins aggregating the purchase price of the desired article of merchandise.

In operation of my multicolumnar console cigarette merchandising machine, a customer first deposits in coin slot 240 a sum in coins aggregating the purchase price of a desired article. Coin register 238 frees operating bar 106 in a manner known to the art. The customer then actuates the pull rod 63 corresponding to the type and brand of merchandise he desires. If the customer selects a more popular brand located in a container 40, pull rod 68 moves the corresponding link 74 upwardly as viewed in Figure 1 to pivot the proper ejector 86 in a counterclockwise direction about shaft 88. As the ejector 86 pivots, its ejecting head 84 moves into the container 40 to push the lowermost package of cigarettes out of the container. As the connecting link 74 moves upwardly, it moves the operating bar 106 of the machine upwardly in its slots 108. This movement of operating bar 106 pivots cam 154- to drive link 158 to pivot crank 162 and shelf or platform 172 in a counterclockwise direction as viewed in Figure 8 and a clockwise direction as viewed in Figure 1. Shelf 172 receives the package pushed out of the columnar container 40 and retains it until the money deposited in register 238 is accepted. When the money is accepted, operating bar 106 moves downwardly and shelf 172 returns to the full line position shown in Figure 1 under the influence of gravity to dump the package of cigarettes to guide 176 and delivery tray 180.

It is to be noted that in its movement out of container 40 and onto shelf 172 the package of cigarettes pivots arm 188 to move rod 192 to engage a projection 196 or 200 on the associated shift column 23 to prevent the column from interfering with the downward movement of packages in container 40 during the dispensing operation. As has been explained hereinabove, if long, or king size, packages of cigarettes are in the containers 28 and 40, rod 192 engages extension 196. If short or regular length packages are used, rod 192 engages projection 200.

If the customer selects a less popular brand or type of merchandise contained in a columnar container 56, the actuated pull rod 68 moves a connecting link 74, corresponding to the type merchandise selected, upwardly to pivot the associated dispenser 94 in a counterclockwise direction as viewed in Figure 1. This action moves ejecting finger 204 into the container 56 to push the lowermost package out of the container. As the link 74 moves upwardly, operating bar 106 moves up to pivot cam 154 to position shelf 210 to receive the package. After the money has been accepted, the operating bar again moves downwardly and shelf 210 returns to its initial position to permit the package to fall to delivery tray 180.

It is to be understood that if the supply of merchandise in a container 40 and its associated shift column 28 is exhausted, an empty lock 212 closes the opening 148 to prevent operation of the corresponding selecting and dispensing means. Similarly, if the supply of merchandise in a container 56 is exhausted, a member 212 prevents entry of finger 204 into the column. When the empty lock is in operation, pulling one of the pull rods 68 will cause the springs 140 and 142 to yield and permit the safety roller 134 to pivot.

When the machine is being loaded, cover 18 is unlocked and opened. As the cover is unlocked, link 126, shown in Figure 5, moves up to pivot lever 124 to free rack 116 to ensure that the operating bar and dispensing mechanism return to their initial position before the covor is opened. This construction prevents accidental dam.-

age to dispensers which may for any reason have become jammed during the dispensing operation. To load the machine, cover 18 is opened and containers 40 and their shift columns 28 are pivoted about hinge 20 to permit access to containers 56. All containers may then be loaded and the machine again closed.

It will be seen that I have accomplished the objects of my invention. I have provided a multicolumnar console cigarette merchandising machine for dispensing a large number of different types and various brands of cigarettes. My machine takes into account the difference in demand for certain types or brands of cigarettes. It ensures that the supplies of all types and brands are exhausted at substantially the same time. My machine includes means for preventing injury to operating parts of the machine during loading.

it will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of my claims. It is further obvious that various changes may be made in details within the scope of my claims without departing from the spirit of my invention. It is therefore to be understood that my invention is not to be limited to the specific details shown and described.

Having thus described my invention, what I claim is:
