Tobias, Morton Grove, IlL, assignor, by mesne assignments, to Rock-Ola Manufacturing Corporation, Chicago, 111., a corporation of Delaware Filed Sept. 14, 1960, Ser. No. 55,945 7 Claims. (Cl. 221-114) The disclosed improvements relate to mechanisms for dispensing packets, like books of matches, for use particularly in conjunction with cigarette vending machines, the principal object being the provision of a simplified mechanism which can be pre-set to dispense a packet of matches only as the result of pressing a special button provided for that purpose; or in the alternative automatically as the result of each dispensing operation of the associated cigarette vending apparatus.

Viewed from another aspect, the improved dispensing mechanism provides an electro-magnetically actuated pawl and ratchet drive and associated ejecting means which advances uni-directionally to eject one packet of matches at a time from each of several magazine columns in succession, the electro-magnetic drive means being pulsed or energized concomitantly with each electrical actuation of the associated cigarette vending machine, the means for predetermining whether the dispensing of the matches shall be automatic or manual being of a simple mechanical nature and involving a latching device which is disabled if the match-dispensing operation is to be automatic, and which is rendered operative to latch up the dispensing action of the ejecting mechanism in case the operation is to be manual, the customer operating a delivery button in those instances where he desires matches, and that button being efiective to trip out the latch means.

More detailed objects and aspects of novelty and utility relate to particulars of the construction and operation of the embodiment described hereinafter in view of the annexed drawings, in which:

FIG. 1 is a perspective view of the entire match-dispensing unit;

FIG. 2 is a fragmentary sectional detail through one of the magazine columns, as viewed in the direction of line 22 of FIG. 1;

FIG. 3 is a cross-sectional detail through the octagonal gang ejector rod looking along line 33 of FIG. 1;

FIG. 4 is a sectionalized fragmentary perspective detail through the bottom sustaining ledge of one of the magazine columns;

FIG. 5 is a side elevation to enlarged scale of the pawl and ratchet mechanism;

FIG. 6 is a schematic operational and circuit diagram illustrative of the manual pre-set condition;

FIG. 7 is a schematic operational diagram illustrative of the pre-set automatic operation.

The match-dispensing unit depicted in FIG. 1 will usually be installed in the cabinet (not illustrated) of an associated cigarette-vending machine which embodies the usual coin-deposit and control mechanism with brandselection buttons or levers, and a delivery chute or shelf onto which the selected package of cigarettes will be discharged on deposit of the necessary coin or coins, all in a manner well understood in the art.

Such machines frequently include some form of match dispenser operative either automatically or selectively to eject a packet of matches with the package of cigarettes dispensed, the matches invariably being delivered into the same delivery chute or bin as the cigarettes. In many instances, the patron does not intend to take the matches, and it is considered in some types of operation as an economy as well as a safety measure to withhold delivery thereof unless the customer is sufliciently interested to actuate a special delivery means to cause ejection of the 3,095,114 Patented June 25, 1963 matches. In some locations, however, it may be desirable or mandatory to deliver matches automatically with the purchase of the cigarettes.

The match-dispensing mechanism of FIG. 1 consists of a plurality of columnar stacking magazines 10 fabricated from sheet metal and secured in side-by-side assembly as an integrated unit, the columns being open at top and bottom and on one side, the loading of the packets being effected through the open tops, and ejection being effected from the bottoms of the stacks, there being suitable flanges 12 (FIG. 4) at the bottom of each column to support the lowermost packets M in each column, as in FIG. 2.

Attached to the rearward side of the magazine assembly are hook-like upper and lower hanger brackets 14 and 15, respectively adapted to hookingly engage and rest upon a pair of upper and lower cross rods 16 (FIG. 5, also), which are supported interiorly of the associated cigarette-vending machine cabinet (not shown), the lower or discharge ends of the several magazines respectively overlying the discharge bin or receptacle for such machine for the dispensing purposes previously mentioned.

Journalled on lower journal plates 17 and 20 (FIG. 1), aflixed to the opposite lower end walls of the assembly, is a long shaft 21 of octangular cross-section (as in FIG. 3) upon which are spaced a series of angularly olfset ejector pawls or fingers 22 located at relatively equiangular distances about the shaft, one beneath each magazine column.

Each ejector pawl has a pair of integral trunnion arms 23 in which are aligned octagonal holes 24 (FIG. 2) in order that each pawl may be easily set on the shaft in proper angular rotation away from its neighbor. In one complete rotation of the shaft 21 one packet of matches M will be ejected from the bottom of each of the eight magazine columns by the series of eight paddle-like ejector pawls 22, each column at its bottom having a narrow blade spring 27 carried on a cross bar 28 (FIG. 1) so as to be disposed in yieldingly blocking position before the bottom discharge exit of the appertaining column, each spring finger serving to retain the lowermost book of matches in its column, but yielding (as in FIG. 2) to permit passage thereof on forcible ejection by the appertaining pawl 22.

Mounted on the side plate 20 (FIG. 1) is an electromagnetic pawl and ratchet means, generally indicated at 30, for stepping the ejector pawl shaft 21, said mechanism comprising the parts shown to larger scale in FIG. 5, including an especially evolved ratchet wheel 32 fast on the shaft 21 to turn the latter, and a long upstanding drive pawl 34 retained slidably on said plate by means of a pin 35 fixed on the plate and projecting through a long angularly pitched slot 36 in the pawl, so that the latter can move up and down relative to the pin, the pin in turn having a retaining washer 37 secured thereon by one end of a drive spring 38, whereby the pawl is prevented from escaping the pin.

At its upper end the drive pawl is pivotally linked by a pin 39 to one end of a formed lever 40' pivoted on another pin 41 secured in the plate 20, the opposite end of the lever being linked by pin means 42 to the plunger 43 of an electromagnetic solenoid 44 carried by said plate.

The drive spring 38 pulls the pawl down to the limit permitted by slot 36 and accordingly elevates the solenoid 3 ratchet wheel is prevented by a holding pawl 31 pivoted on the plate 20 and urged by a spring 313 into the ratchet teeth.

When the coil 44 is energized the pawl 34 is elevated to its cocked or advancing position with a further tensioning of the drive spring 38, it being noted that the long slot 36 is angled somewhat toward the ratchet wheel so that the pawl teeth tend to withdraw outwardly as well as upwardly in the solenoid-driven or setting phase of their reciprocable travel, and during the return or working stroke when solenoid 44 is deenergized the driving pawl 34X will engage first in the shallower teeth as aforesaid -to execute the shaft-advancing phase of the stroke, while the stop pawl 34Z will properly approach the next stopping tooth 32S owing to the pitch of the long slot 36.

Thus, if the selective latching control means is not operative, a proper pulsing of coil 44- in conjunction with the action of the drive spring 38 will always effect one ratchet-advancing reciprocation of the drive pawl 34 sufficient to cause ejection of one packet of matches by one of the ejector pawls 22.

The selective latching control means, shown in FIG. 5, comprises a rockable latch lever 50 in the form of a metal stamping having one arm 51 provided at its end with a latching offset or nose 52, and another arm 54 having an offset striker tab 55 at its free end, adapted to engage a smaller offset stopping lug 56 struck out from the plate 20 and situated below the striker tab and just above the pivotally supported part of the solenoid lever at 41.

The two latch-lever arms 51 and 54 are preferably formed at right angles to each other with an offset intermediate portion 58 of the metal turned over at their juncture and pierced to receive a pivot pin 59 fixed on the base plate. Also formed as part of the inter mediate offset 58 are two oppositely disposed springanchoring hooks 59A and 59M, respectively located on opposite sides of a reference radius from pin 59 extended generally toward the pivotal axis of the solenoid drive lever at pin 41.

A selector spring 60 is anchored at one end on the pin 41 and has a loop 61 at its opposite end engageable optionally with one or the other of the two hooks 59A or 59M, which are respectively the hooks for automatic and manual selection positions.

When the spring 6!) is anchored on the hook 59M, the selector lever 50 is urged counterclockwise and will thrust the latching nose or pawl 52 against the riding edge portion 34E of the driving pawl (dotted lines, FIG. 7) in readiness to enter the latching notch 34N thereof automatically when the driving pawl rises into the setting or cocking position, as illustrated schematically in FIG. 6, with the result that the return driving stroke cannot be completed until the latch is released by pivoting of the latch lever 50 clockwise.

Release of the latch lever is effected manually at the option of the patron of the machine as the result of his pushing a match-delivery button 70 (FIGS. 1 and 6) conveniently located, for instance on top panel portion 71 of the cigarette or other vending machine with which the novel packet dispensing mechanism is associated, said button in turn actuating a stiff drive wire 72 guided in a flexible cable tube 73 anchored at its lower end on the plate 20 by means of a cleat 74, there being a plunger head 75 secured to the lower end of the drive wire in a position overlying the striker tab 55 on the latch lever.

Thus, when the patron depresses the delivery button 70 the drive wire is forced down and the plunger 75 engages the offset tab 55 rocking the latch lever clockwise to withdraw the latching part or pawl 52 so that the ratchet drive lever can complete its spring-urged ratchetadvancing stroke and dispense one packet of matches.

For automatic operation the selector spring 69 is transferred to the hook 59A, which rocks the latch lever 50 clockwise and maintains it constantly in non-latching relation to the drive pawl (as in FIG. 5) with the result that a packet of matches will be dispensed with every pulsing of the solenoid coil 44, since complete reciprocation of the drive pawl results when the latch lever is thus disabled in the automatic or 59A hook position of the selector spring, as aforesaid.

In commercial adaptations of the novel dispensing unit to cigarette vending machines, it is preferred that the coil 44 shall be pulsed concurrently with each and every cigarette-dispensing operation, it being usual in such machines to employ some form of electrically-controlled or actuated package-ejecting means (not shown) for effecting the ejection of a package of cigarettes after the brand selection has been made by the patron and the proper coins have been deposited. Such package ejector actuators may be in any of the well-known forms such as an electric motor or a solenoid drive mechanism or the like, which will usually be energized through the intermediary of a relay or like dispensing control switch means.

Accordingly, the dispensing coil 44 of the present disclosure is preferably connected for energization by such cigarette-dispensing control switch means, whatever its form, so that the match-dispensing coil 44 and lever 34 will be operated every time a package of cigarettes is dispensed; and, depending on the setting of the selector spring 6'3, a packet of matches will be dispensed either automatically with the cigarettes or as a result of manual opeartion of the button 70.

One illustrative circuit arrangement embodying the aforesaid concurrent operation of the matchand cigarette-dispensing mechanisms is depicted in FIG. 6, wherein the coil 44 is connected for coaction with a cigarette dispensing control switch means which may be, for example, the switch of a dispensing or vend relay in the associated cigarette machine, and which will include normally open contacts 81 and 82 connected to enengize upon closure, via conductor 83, the match-packet ejecting coil 44-, said switch means also preferably including additional contacts 35, 86, closable simultaneously with contacts 81 and 82 to energize the cigarette-ejecting or dispensing control means schematically indicated at 86, as by energizing a suitable relay, ejector, or other electrical means 87, which may be a motor type cigarette-pack ejector, or a solenoid-driventype of ejector, such as previously mentioned, and both of which are well-known in the art, whereby concurrent energization of the electrical ciganette-dispensing means 8687, whatever its form, and the match-packet dispensing coil 44 will be achieved.

The described match-dispensing mechanism with particular attention to the electromagnetic actuating mechanism thereof has the advantage that on manual setting repeated operations or" the cigarette dispenser control switch and circuit produce substantially no mechanical action in the match-dispensing mechanism, the plunger of the solenoid remaining down until the manual neleasing operation is effected with the result that the momentary concomitant energization of the solenoid coil is substantially the only action produced by actuation of the cigarette dispensing control switch means, and this energization produces'no appreciable mechanical movement in the parts of the match-dispensing mechanism, and the impedance of the solenoid in this condition is at a maximum so that curnent and heating effects are reduced as well for unlimited repeat operations of the cigarette machine until such time as the manual release is operated.
