VENDING MACHINE Filed Dec. 28, 1956, Ser. No. 631,247 18 Claims. (Cl. 221-104) This invention relates to vending machines, and more particularly to cigarette vending machines.

Among the several objects of the invention may be noted the provision of dispensing apparatus for a vending machine, and more particularly a cigarette vending machine, which is adapted to carry a relatively large number of diflerent brands of cigarettes, and a relatively large number of packs of each different brand, and which despite its high capacity is relatively compact in size; the provision of dispensing apparatus of the class described wherein two tiers of magazines are provided, each magazine having an ejector, packs ejected from magazines in the upper tier dropping out to purchasers behind the magazines of the lower tier, and wherein the magazines, while being adapted to hold a relatively large number of packs, are relatively low in height so that the apparatus may be housed in a cabinet of relatively low height without having the packs delivered to purchasers at an unduly low level; the provision of dispensing apparatus of the class described in which each magazine is of a special construction adapted to hold a substantially vertical primary stack of packs and a substantially vertical reserve stack of packs behind the primary stack and which has means for pushing the reserve stack bodily forward to dispensing position when the primary stack is depleted in such manner that the reserve stack remains sub stantially vertical, as is desirable for display purposes; the provision of dispensing apparatus of this class in which each magazine is of such construction that it may be easily loaded with packs for both the reserve stack and the primary stack fro'm the front of the apparatus; the provision of dispensing apparatus of the class described in which there is a special interlocking means between the two tiers which acts, upon operation of any ejector of one tier, to lock out of operation the ejectors of all the magazines of the other tier; the provision of dispensing apparatus of the class described which includes means whereby both tiers of magazines may be controlled by a single coin control mechanism, provision also being made for carrying packs of different prices in different magazines; and the provision of dispensing apparatus of the class described which is relatively economical to manufacture and reliable in operation. Other objects and features will be in part apparent and in part pointed out hereinafter.

The invention accordingly comprises the constructions hereinfter described, the scope of the invention being indicated in the following claims.

Corresponding reference characters indicate corresponding parts throughout the several views of the drawmgs.

Referring to the drawings, there is indicated at 1 in Fig. 1 a cigarette vending machine cabinet standing onlegs 3. The cabinet has a bottom 5, left andright side walls 7 and 9 (left and right being as viewed from the front of the cabinet), attop wall 11, and afront door 13. Thedoor 13 is entirely removable from the cabinet, any suitable means (not shown) being provided for holding it in place and locking it against unauthorized removal. The door has an inclinedfront panel 15. Shown at the upper right of the door are theusual coin slot 17 andcoin return knob 19.

Housed in the cabinet is a dispensing apparatus of this invention designated in its entirety by thereference character 21. This dispensing apparatus comprises a frame including left andright side walls 23 and 25 which are mounted on the cabinet bottom 5. Located between theside walls 23 and 25 are upper and lower tiers T-1 and T-2, respectively, of magazines M.

Each tier may include eleven magazines, for example, making a total of twenty-two magazines for twenty-two different brands of cigarettes. Tiers T-l and T-2 are substantially identical and a description of one will extends from one side wall to the other.

Fig. 2 is a front elevation of the dispensing apparatus sufiice for both. Each tier includes a forwardhorizontal shelf 29 which extends between theside walls 23 and 25. Fixed to the front of thisshelf 29 is an upstanding vertical plate 3-1. On the shelf is adraw bar 33 which Thisdraw bar 33 is slidable on theshelf 29 transversely with respect to the length of the bar and in forward and rearward direction as regards the entire dispensing apparatus. Extending rearward from the left end of the draw bar is ahorizontal arm 35 carrying astud 37 slidable in ahorizontal slot 39 in theleft side wall 23. Extending rearward from the right end of the draw bar is ahorizontal arm 41 carrying astud 46 slidable in ahorizontal slot 45 in theside wall 25.

The shelf 2.9 of the upper tier T-l has a rearward apron 47 sloping downward toward the rear of the apparatns. Theshelf 29 of the lower tier T-2 has a downwardly extending rearwardapron 49 inclined toward the front of the apparatus. Otherwise these shelves are the same. Extending between thearms 35 and 41 of thedraw bar 33 for the lower tier T-2 is anapron 51 having a downwardly extending forwardlyinclined portion 53. The magazines M of the upper tier, as shown in Fig. 4, are higher than the magazine M of the lower tier, but

a otherwise the magazines of the two tiers are substantially identical.

" Each magazine of each tier has an ejector B. Each of these is similar to the ejectors shown in the copending coassigned Ridings et al. application Serial No. 530,333, filedAugust 24, 1955, issued. as Patent No. 2,823,782, February 18, 1958; Each comprises ahead 55 havingatop flange 57 and avertical web 59 which extends down through aslot 61 in theshelf 29. The forward ends. of thewebs 59 ofheads 55 of each tier engage the rearward edge of thedraw bar 33 for that tier. Arod 63 extends forward from eachhead 55 through an opening 60 inthevertical front plate 31. Eachrod 63 has aknob 65 fixed on its outer end. The front door of the cabinethas openings such as indicated at 67 for the knobs. These openings are of larger diameter than the knobs so that the front door of the cabinet may be taken off over the knobs. Thus, there is an upper row of ejectorsE including knobs 65, one for each magazine M of the upper tier, land a lower row of ejectors E including knobs .65, one for each magazine M of the lower tier.

Thedraw bar 33 of either tier is adapted to be moved forward from the retracted rearward position shown for the lower tier in Figs. 4, 6 and 8 and for both tiers in Fig. 7 toward the front of the apparatus (toward the vertical plate 31) by pulling out any one of theejector rods 63 for the respective tier. Each tier is provided with lock-out means to prevent pulling out more than onerod 63 of the tier at a time. This is shown to comprise a series ofinterlock tumblers 69 mounted to be slidable laterally of the apparatus under theshelf 29 betweenend stops 71 and 73. The tumblers are guided by'ears 75 struck from theshelf 29. Each of theheads 55 has anose 77 at the forward end of ahorizontal flange 79 at the bottom of theweb 59.Flange 79 is belowshelf 29. The arrangement is such that when any onerod 63 of a tier is pulled out, therespective nose 77 spreads the entire series of tumblers of the tier apart to look all theother rods 63 of the tier against being pulled out. The construction of the tumblers is similar to that shown in U.S. Patent 2,377,413, and since the details thereof 7 do not form a part of this invention, will not be further described.

As to each tier, the magazines M are formed byvertical partition plates 81 which extend in front-to-rear vertical planes above theshelf 29 and over ahorizontal shelf 83 extending between theside walls 23 and 25 immediately rearward of and above theshelf 29. Each of the partition plates 81 (except the two outermost plates at the sides of the apparatus) is common to and 1' constitutes the side wall for each of the two adjacent magazines so that there is no space between the magazines (see Fig. 3). Thepartition plates 81 are secured on therearward shelf 83. The bottom edges of the horizontal direction with the reserve stack remaining substantially vertical. As shown best in Figs. 3, 4 and 6, this means comprises a substantiallyvertical pusher plate 87 extending transversely between the twopartition plates 81 which constitute the side walls of the magazine M for engaging the rear of the reserve stack. This pusher plate is biased forward and maintained substantially vertical by a spring-biased lazy tongs generally designated 89. These lazy tongs comprise a pair of crossedlevers 91 and 93 pivotally connected where they cross at 95.Lever 91 is pivotally connected at one end (constituting its upper end) to the rear of the pusher plate as indicated at 97. At its lower end it has aslot 99 receiving atransverse rod 101 extending between thepartitions 81. Lever 93- is pivoted at one end (constituting its upper end) on :atransverse rod 103 extending between thepartitions 81. At its lower end it has aslot 105 receiving a P111107 carried by thepusher plate 87. Aspring 109 is connected between thelevers 91 and 93 which tends to lengthen the lazy tongs and thus biases the pusher plate forward. It may be desirable to design the lazy tongs so that thepusher plate 87, when in retracted position, is slightly angled rearward from its bottom to its top to avoid the possibility of wedging thepartition plates 81 are stepped as indicated at 85, the

bottom edges of the forward portions of the plates being somewhat above theshelf 29 to provide clearance for thedraw bar 33. As to each magazine, when the ejector head therefor is in its rearward retracted position, it

is adapted to support a primary stack S4 of cigarette packs P in a substantially vertical dispensing position toward the front of the magazine (see the lower tier magazine shown in Fig. 4).Shelf 83 is adapted to support a reserve stack S-Z of packs P in a retracted substantially vertical position rearward of the primary stack S-1 (see the magazines shown in Fig. 4 and the upper tier magazine shown in Fig. 6). Theshelf 83 is located above the shelf 29 a distance somewhat greater than the thickness of a pack P, and located above the ejector heads 55 on shelf 29 a distance less than the thickness of a pack P, being preferably located a distance above these heads a distance corresponding to about one-half the thickness of a pack -P.

Each magazine M includes means for moving the reserve stack S-2 into dispensing position when the primary uppermost packs in the primary stack which would prevent them from dropping. A side plate 111 (which may be formed integrally with the pusher plate 87) extends forward from the pusher plate at one side (the right side) of the magazine M. This side plate extends forward from the pusher plate a distance slightly greater than the length of a pack P, and, in particular, a distance slightly greater than the length of a king-size pack. Such king-size packs are shown in the drawings. If a magazine is to hold regular size packs, a filler piece such as indicated in dotted lines at 113 in Fig. 6 is provided on the front of the pusher plate, this filler piece being such that the distance from it to the forward edge of the side plate 111' is slightly greater than the length of a regular size pack.

Aflap 115 is pivoted by hinge means such as indicated at 117 on a vertical axis at the forward edge of theside plate 111. This flap is swingable between an inwardly extending transverse position (see Fig. 3), wherein it acts as a partition for separating the primary stack S-1 and the reverse stack S-2, and a forwardly extending position'at one side of the magazine (see Fig. 10) for front loading of the magazine, as will be made clear. It is a biased to swing outward to the stated forwardly extend ing loading position by aspring 119. It has afinger 121 engageable with theadjacent partition 81 for holding it in its transverse stack-separating position against the bias of thespring 119. The bottom edge of theflap 115 is spaced above the shelf 83 a distance somewhat greater than the thickness of a pack P. 7 Each tier of magazines is provided with adoor 123 pivoted as indicated at 125 at its lower edge on acrossbar 127 extending between the side walls. 23 and 25'. Latch means such as indicated at 129 is provided for latching this door in vertical position closing the open fronts of the magazines. As to each magazine, thefinger 121 engages theadjacent partition 81 and holds theflap 115 in its stack-separating position when thepusher plate 87 is in its retracted position shown in Fig. 3, but is released when the pusher plate has moved forward to the position shown in Fig. 10 and the door .123 is opened to'release the flap. 115 to swing outward to loading posi; tion under the bias ofspring 119. 1 'Arockshaft 131 extends between theside walls 23 and. 25 toward the rear of the apparatus generally at the elevationat the top of the lower tier T1. A-similar rockshaft 133 extends between theside walls 23 and25 directlybelow the shaft 13.1. and at an elevation some-i what above therearward shelf 83 of the lower tier T2.

I These rockshafts are journaled at their ends in openings in theside walls 23 and 25' such as indicated at;

Fixed on theupper shaft 131 on the inside of theright side wall 25 is afirst lever 137 which constitutes a first member of an interlock between the tiers for locking out of operation all the ejectors E of one tier upon operation of any ejector E of the other tier. Fixed on thelower shaft 133 is alever 139 which is identical to thelever 137 except that it is reversed in position.Levers 137 and 139 are coplanar. Each is sector-shaped. The upper lever .137 has an integral upwardly extending crankarm 141. Alink 143 connects thestud 46 of the upper tier to the crank arm .141. Thelower lever 139 has an integral downwardly extending crankarm 145. Alink 147 connects thestud 46 of the lower tier to thearm 145.

'Each of thelevers 137 and 139 is formed with anotch 149, oneside 151 of this notch constituting a shoulder for engagement with one or more of a series of coincontrolled latches L1, L2, and L-3. The arcuate end of each sector-shapedlever 137 and 139 is formed with a series of ratchet teeth v153 and anotch 155. When the draw bars 33 of both tiers are in the rearward retracted position illustrated in Fig. 7, thelevers 137 and 139 occupy the retracted position shown in Fig. 7 wherein theirshoulders 151 are spaced from the latches L-1, L2 and L-3. Theshafts 131 and :133 are spaced from one another a distance less than twice the radius of thelevers 137 and .139, the arrangement being such that when theupper lever 137 swings clockwise away from its retracted position shown in Fig. 7, it blocks the lower lever 1139 from being swung counterclockwise away from its retracted Fig. 7 position, and conversely, when thelower lever 139 swings counterclockwise away from its retracted position, it blocks theupper lever 137 from being swung clockwise 'away from its retracted position. Theupper lever 137 is swung clockwise away from its retracted position when any ejector E of the upper tier is pulled out to move theupper draw bar 33 forward. Thelower lever 139 is swung counterclockwise away from its retracted position whenever any ejector E of the lower tier is pulled out to move thelower draw bar 33 forward. The opposed side edges oflevers 137 and 139 may be cut away to arcuate shape as indicated at 157 for clearance purposes.

Means is provided for biasing theupper shaft 131 to rock counterclockwise and for biasing thelower shaft 133 to rock clockwise, as viewed in Fig. 7. As shown in Fig. 5, this means comprisesarms 159 and 161 fixed on the left ends ofshafts 131 and 133, respectively, outside theleft side wall 23, and springs 163 and 165 connected between the left side wall andarms 159 and 161, respectively.Spring 163 thus biases theupper interlock lever 137 and theupper draw bar 33 to the retracted position shown in Fig. 7, determined by the engagement of theupper knobs 65 with theupper plate 31.Spring 165 thus biases thelower interlock lever 139 and thelower draw bar 33 to the retracted position illustrated in Fig. 7, determined by the engagement of thelower knobs 65 with thelower plate 31.

A latching means 167 is provided for theupper interlock lever 137, and a latching means 169 is provided for thelower interlock lever 139. Each of these 'latching means is identical, comprising apawl 171 pivoted on the inside of theside wall 25 by means of astud 173 and engageable with the arcuate end of therespective lever 137 or 139. The pawl is biased toward the centered position such as is illustrated for the upper pawl in Fig. 8 by an overcentering spring mechanism including arod 175 slidable in aU-shaped bracket 177 pivoted on the inside of theside wall 25 by means of astud 179. Aspring 181 biases the rod to move outward away from the pawl. Whenlever 137 orlever 139 is in its retracted position (see Fig. 7), the tip of therespective pawl 171 is received in thenotch 155 and the pawl is cocked at an angle to therod 175. When thelever 137 or 139, as the case may be, swings away from its retracted position, the series ofratchet teeth 153 on the lever engages the respective pawl, and the pawl is swung to an oppositely angled position to lock into the ratchet teeth and prevent the lever from swinging back to retraoted position unless the lever is swung far enough for the series of ratchet teeth to disengage completely from the pawl (see the position of theupper lever 137 and the pawl therefor in Fig. 8). This arrangement compels full-stroke operation of any ejector E once it has been pulled out far enough for therespective pawl 171 to latch on to the respective ratchet teeth. However, any ejector B may be pulled out a short distance before the respective pawl engages the respective ratchet teeth.

The late-hes L-1, L2 and L-3 correspond to the latches L1, L2 and L-3 shown in the copending coassigned application of Alvin W. Holstein et al. Serial No. 589,918, filed June 7, 1956. When any one of these latches is in its locking position projecting through anopening 183 in theside wall 25, all of the ejectors E are locked against being pulled out any more than a small distance corresponding to the small angle through whichlever 137 orlever 139, as the case may be, may rotate before itsshoulder 151 engages a latch Ll, L-2 or L-3. This limited movement of eitherlever 137 or 139 is not sufficient for the respective ratchet teeth to latch on to therespective pawl 171. In order that any ejector E may be completely pulled outfor full-stroke operation, it is necessary that all three of the latches L-l, L2 and L-3 be retracted out of the path of thelevers 137 or 139.

Each tier of magazines is shown as having rear andfront price shafts 185 and 187 corresponding to the rear andfront price shafts 155 and 157 shown in said copending application Serial No. 589,918. As in said application Serial No. 589,918, these shafts carryprice arms 189 and 191, respectively, corresponding to thearms 169 and 171 shown in said application adapted to be located for engagement byribs 193 on theheads 55. They also carryarms 195 and 197, respectively (see Fig. 9) on the outside of the right side wall 25 (corresponding toarms 159 and 161 shown in Serial No. 589,918). Thearm 195 for the upper tier is linked to thearm 195 for the lower tier by alink 199 having lost motion connections such as indicated at 201 with eacharm 195, so that thelower arm 195 may rotate to pull down thelink 199 without moving theupper am 195, and, conversely, theupper arm 195 may rotate to move thelink 199 down without moving thelower arm 195. Similarly, the upper andlower arms 197 are connected by alink 203 having lost motion connections such as indicated at 205 with each of thearms 197.Link 199 operates alever 207 which corresponds to thelever 135 shown in said copending application Serial No. 589,918, and link 203 operates alever 209 which corresponds to thelever 149 shown in said copendin'g application. Springs such as indicated at 211 and 213 bias thelevers 207 and 209 in clockwise direction as viewed in Fig. 9, and tend to maintain thelinks 199 and 203 raised. Awire 215 corresponding to thewire 199 shown in said copending application has end pontions hooked aroundstuds 217 and 219 on thelevers 207 and 209 in such manner that whenlever 209 is swung counterclockwise, the wire pulls up thelever 207, but whenlever 207 is swung counterclockwise, the lever 20 9 is not operated. From here on the action is the same as that disclosed in the stated copending application Serial No. 589,918, and reference may be made to said application for a complete disclosure of the coin-controlled mechanism for operating the latches Ll, L2 and L3.

Each magazine M is provided with means for moving itspusher plate 87 rearward whenever its ejectorE is operated in order to relieve the bias or pressure of the reserve stack S2 on the primary stack S1 so that the primary stack may drop freely downward. This means includes aratchet 221 projecting rearward from thepusher plate 87 of the magazine. Each tier of magazines has arockshaft 223 extending transversely between theside walls 23 and 25 under therearward shelf 83. Eachshaft 223 carries a series ofpawls 225 which extend throughopenings 227 in therespective shelf 83 for en gagement with theratchets 221. Eachshaft 223 has acrank arm 229 fixed thereon on the inside of theright side Wall 25.Thevarm 229 for theupper shaft 223 is connected by alink 231 to thearm 141 and thearm 229 for thelower shaft 223 is connected by asimilar link 231 to thearm 145. The arrangement is such that when any ejector E of the upper tier is pulled out, theupper rockshaft 223 is rotated counterclockwise as viewed in Fig. 7 (clockwise as viewed in Figs. 4 and 6), and thepawls 225 thereon engage theratchets 221 of thepusher plates 87 of the upper tier to move them rearward against the bias of the respective springs 109. Similarly, when any ejector E of the lower tier is pulled out, thelower rockshaft 223 is rotated counterclockwise as viewed in Fig. 7 and thepawls 225 thereon engage theratchets 221 of thepusher plates 87 of the lower tier to move them rearward against the bias of the respective springs 109. Theratchets 221 are of such length as to allow for loading any magazine with either king size or regular size packs P.

Each of thedoors 123 for the upper and lower tiers T-l and T2 is provided with a series ofwindow openings 233, one for each magazine M. Thecabinet door 13 has upper and lower windows W-l and W-2 for viewing of the packs in the magazines throughopenings 233. Thedoor 13 is also shown as provided behind windows W- l and W-2 withcasings 235 havingwindow openings 237 which register withopenings 233. Thedoor 13 has an access opening 239 below the lower row ofknobs 65. Behind opening 239 is atrough 241 for receiving packs ejected from the magazines. Extending around the lower tier T2 is aguide plate 243 for guiding packs discharged from the upper tier around the rear of the lower tier. Below the lower tier T2 is aguide plate 245 down which packs slide to thetrough 241.

Operation is as follows:

As to any magazine M, as long as there are two or more packs P in the primary stack S-l resting on theejector head 55, and as long asdoor 123 in front of the magazine is closed, thepusher plate 87 is held back in rearward retracted position by engagement of theflap 1 15 with the rear of the primary stack, the latter being pushed forward against the door 123 (see Figs. 3 and 4 and the upper magazine in Fig. 6). When there is only one pack left in the primary stack resting on theejector head 55, thepusher Plate 87 is held back in retracted position by engagement of the lowermost pack of the reserve stack S-2 with this one pack left in the primary stack.

To obtain a pack P from a magazine M of either t-ier T-l or T2, a customer inserts the appropriate amount in coin in thecoin slot 17, then pulls out theknob 65 for this magazine and returns the knob to its rearward retracted position. Assuming that the magazine has two or more packs in the primary stack S-1 and a full reserve stack S2, on pulling out theknob 65 theejector head 55 is drawn out from under the primary stack and the entire primary stack drops down on to theforward shelf 29. Then, when theknob 65 andhead 55 return to retracted position, the head pushes the lowermost pack of the primary stack rearward off theshelf 29 under therearward shelf 83. In the case of dispensing from a magazine of the upper tier, the ejected pack slides down theplate 243 around the rear of the lower tier to theplate 245 and then slides down the latter plate to thetrough 241. In the ease of dispensing from a magazine of the lower tier, the ejected pack slides forward down theflange 53 to the trough. When. the knob is pulled out, thepusher plate 87 is moved rearward by the action of therespective pawl 225 on therespective ratchet 221, to release the pressure on the primary stack so that it may drop freely downward onto theshelf 29.

On pulling out anyknob 65 of the upper tier, all the other knobs of the upper tier are locked out of opera-' tion by the action of thetumblers 69 of the upper tier, and all the knobs of the lower tier are locked out of operation by the movement of theupper interlock lever 137 away from its retracted position of Fig, 7 to the position shown in Fig. 8. On pulling out any knob of the lower tier, all the other knobs of the lower tier are locked out of operation by the action of thetumblers 69 of the lower tier, and all the knobs of the upper tier are locked out of operation by the movement of thelower interlock lever 139 away from its retracted position of Fig. 7. It willbe understood by reference to the above-noted copending application Serial No. 589,-, 918, that pulling out of the knob of any magazine farther than the limited distance permitted by latches L4, L-2 and L-3 is precluded unless an amount in coin corresponding to the price for the brand in that magazine has been inserted, and that, assuming that the proper amount has been inserted, all three latches L-1, Ir-2 and L-3 will be retracted out of the paths ofinterlock levers 137 and 139.

When the last pack of the primary stack S-l in a magazine drops down onto theshelf 29, the pusher plate 87 (under the bias of spring 189) pushes the entire reserve stack S-2 in the magazine bodily forward into vertical dispensing position, flap remaining in its transverse position and coming into engagement with thedoor 123. Dispensing may then proceed from the reserve st-ack until it is exhausted. With theflap 115 engaging thedoor 123, there is no pressure on the stack to impede its dropping downward, and it makes no difference that theratchet 221 has moved forward beyond the range of thepawl 225.

To reload a magazine, therespective door 123 is swung down to open up the front of the magazine. Assuming that the reserve stack for this magazine has previously been pushed forward to dispensing position, opening thedoor 123 frees theflap 115 so that it swings open (see Fig. 10). Then, packs may be inserted straight in from the front of the magazine to replenish the reserve stack. Next, theflap 115 is moved to its transverse position to act as a pusher, and additional packs inserted from the front to make up a primary stack, the reserve stack being pushed back to retracted position by the act of inserting the additional packs and pushing them against the flap. Once the reserve stack has been pushed back, it drops down behind a pack which remains on theejector head 55 in view of the spacing of the bottom edge of the flap above the ejector head, and this holds the reserve stack in retracted position.

As above described, each magazine in each tier includes means for holding a reserve stack and meansfor moving the reserve stack into dispensing position when the primary stack is depleted. This provides for maximum capacity for all brands. It will be understood, however, that the reserve stack feature may be omitted as to certain of the magazines in one tier, or in both tiers, or even as to all the magazines in one tier, these magazines then being utilized for slower-selling brands. In any case, however, at least some of the magazines in at least one tier will have the reverse stack feature.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
