Application February 28, 1947, Serial No. 731,526
I The present; invention relates to dispensing or vending machines for articles of predominantly two-dimensional character; more particularly the invention relates to vending machines of the type adapted to sell flat paper goods such of operation and s mplicity of manipulation as will assure popular acceptance thereof, and particularly newspaper vending machines have, therefore, not found the widespread use of which they are potentially capable; v
Most of the known machines are liable to fail,
- or operate defectively, under a variety of different circumstances, such as humid weather conditons which may cause the stack of papers to adhere to one another, resultin in the delivery of more than one paper and congestion of the supply chute.- Also, the varying degrees of thickness of newspapers, such as the difference between Sunday and week day editions, have presented serious difiiculties in this respect. Furthermore, many newspaper vending machines require that a purchaser'use both his hands simultaneously, one for operating the release button and the other one for pulling the paper from its magazine, and lack of coordination of the required operations frequently causes the dispensed paper to be wedged in, leaving the machine disrupted and the customer unsatisfied and annoyed.
1 Furthermore, certain of the known vending est need for machines of this type exists in localities of medium or small turnovers that are unable to support a newspaper vendor.
- Broadly, it is an object of the present invention to provide a vending machine for news- "papers, magazines and the like, which is simple in construction, reliable in operation and convenient to manipulate More specifically, it is an object of the pres 'ent invention to furnish a machine of the type referred to which may be depended upon to deliver the articles contained in its magazine individually, no matter what the individual thickness of any one or all of said articles.
It is another object of the' present invention to furnish a vending machine of the'type referred machines are of such construction as to require 4 Claims. (Cl. 312-94) to which requires no adjustment to adapt it to varying degrees of thickness of the dispensed articles.
It is yet another ob ect of the present inven tion to furnish a dependably operating newspaper vendin machine which a purchaser may conveniently operate with one hand only.
Furthermore, it is an object of the present invention to furnish a machine of the type referred to which may be manufactured at such low cost as to lend itself to profitable use in places of small as well as large turnovers.
It is a further object of the present invention to provide a machine, of the type described, with exteriorly visual means adapted to indicate the amount of supply left in its magazine.
Additionally, it is an object of this invention to so construct a newspaper vending machine of the type under consideration, that upon delivery of the last copy it will automatically warn prospective purchasers of its inability to deliver any more papers.
These and other objects of my invention will be apparent from the following description of the accompanying drawing which illustrates a preferred embodiment thereof, and wherein Figure 1 is a perspective view of a newspaper vending machine embodying my invention with its magazine partly withdrawn;
Figure 2 is a sectional side elevation of the same machine taken slightly to the right of the center thereof;
Figure 3 is a sectional plan view of the machine taken along line 3-3 of Figure 2;
Figure 4 is a bottom plan view of the maga zine removed from the machine;
Figure 5 is a sectional detail view of the release mechanism of my invention, taken along line 5--5 of Figure 2 with certain parts broken away to expose structure underneath;
Figure 6 is a fragmentary perspective of a portion of the magazine, as viewed from below, with certain parts broken away'to expose all of the release mechanism for the last paper dispensed by the machine;
Figure 7 is a sectional side elevation of an arrangement for indicating the amount of supply left in the magazine: and
Figure 8 is a fragmentary front elevation show; 7 ingmechanism adapted to close automatically the coinslot of my machine upon exhaustion of its supp/1y.
Asis apparent from the figures, the illustrated embodiment of my invention comprises a pedestal 1n the form of a housing 10 and a removable magazine 29. The housing H1 is composed of two side walls H and I2 respectively, a rear wall l3 and a front wall 14, the latter being materially shorter than the side walls so as to form a large window adapted to slidably receive the magazine 20. The side walls H and I2 are therefore provided with horizontal fillets [5 for the magazine to rest upon, as shown in Figure 2.
An inclined chute or slide I6 is suitably supported in the housing [0 and descends obliquely from the rear wall l3 to the lower edge of a horizontal slot I! provided in, and extending across, the lower part of front wall [4. Chute I6 projects a short distance beyond the front wall I4,
as shown in Figure 2, and is provided with an upwardly directed stop edge l8 to form a delivery trough. The projecting end of chute I6 and the described stop edge E8 maybe recessed at the center, as shown in Figure 1, to facilitate removal of the delivered articles. Suitable apertures are preferably arranged in the described delivery trough, at low points thereof, to prevent accumulation of moisture. At the top of slot I? the front wall I4 is bent outwardly and backwardly, as shown in Figure 2, to form a protective roof over the delivery trough while avoiding sharp edges which might injure a customer's hand.
A lid [9 is hinged to the top of rear wall l3, as shown, and may be provided with a suitable look (not shown) to prevent opening by unauthorized persons.
The magazine 20 has two side walls 2| and 22 rigidly held in-spaced parallel relation in any suitable manner such as by means of a ceiling 23. Horizontally positioned within the magazine '25 are a plurality of superimposed sheets 24, preferably made of a light-weight metal, with a newspaper 25 placed between each two adjacent sheets. The front edges of every one of sheets 24 possess forwardly directed lips or lugs 26 with the lugs of each' two successive sheets 24a and 242) being displaced relative to one another in horizontal direction, as may best be seen at 26a and 26b in Figure 5.
The rear edge of the lowermost sheet 24 rests upon a bar 2! extending longitudinally across the magazine and supported by two lateral arms 28 the upper ends of which are pivoted to the side walls 2| and 22 of the magazine, as may be seen from Figure '2. The ends of carrier bar 21 project somewhat beyond lateral arms 28 and engage arcuate slots 29 receding from the rear edges of side walls 2! and 22 respectively to points vertically below the pivots of arms 28. The forwardly protruding lug or lip 26a of the lowermost sheet 24a rests upon a stud or roller 30 pivoted to, and projecting rearwardly from, the lower end of a substantially vertical lever arm 33.
Near its rear edge each plate 24 has two elongated apertures 35 located at opposite corners, as shown in Figures 3 and 4, and each aperture is slidably engaged by a vertical guide rod 36 extending from the ceiling to the bottom of the magazine, somewhat in front of carrier bar 21. The lower ends of guide rods 36 are slightly curved in rearward direction, as shown in Figure 2, and are supported by another longitudinal bar 31 the ends of which are securely mounted in the side walls 2i and 22 some distance below the previously mentioned carrier bar 21.
A vertical partition 38 is located adjacent to the front edges of all the sheets 24 and forms a forwardly directed channel or recess 39 extending all the way from the top to near the bottom of the magazine 20 and adapted to accommodate the previously mentioned lugs or lips 26 of the various sheets 24. The partition 38 and the front wall of its channel or recess 39 are arranged to maintain sheets 24 in a rearwardly shifted position in which the guide rods 36 engage the forward portions of the elongated apertures 35 and wherein the rearward edges of the sheets 24 are dependably maintained in vertical alignment above longitudinal carrier bar 21.
The forwardly projecting lips or lugs 26a and 26b of each two successive sheets 24a and 2419 are laterally dis laced from one another, as previously pointed out, and while the degree of relative displacement of said lugs need not necessarily be such that each two successive lugs will be completely clear of one another in vertical direction, as shown in Figure 5, at least part of the lugs of each two successive sheets should be dispesed over distinctly separate areas vertically thereof. In the illustrated embodiment the arrangement is such that the lugs 26a of every odd number in the sequence of superimposed sheets and also the lugs 26b of every even number thereof are vertically aligned with one another.
As has likewise been previously pointed out, the roller 39 supporting the lug of the lowermost sheet is pivoted to the lower end of a substantially vertical lever arm 33 disposed exteriorly of the recessed portion of partition 38. Arm 33 forms part of a bell crank lever 3i the center 32 of which is pivoted to the exterior wall of recess 39 near the top of the magazine, as shown in Figures 2 and 5. Bell crank 3! has another arm 34 extending substantially in a horizontal direction to the right hand side of the magazine, as viewed from the front, and protruding through a suitable slot in side wall 22. When the free end of lever arm 34 is moved upwardly to turn bell crank 3! in clockwise direction, as viewed in Figure 5, roller 30 is withdrawn from underneath the lug 23a of the lowermost sheet 24a and moved into a position vertically below lug 26b of the next sheet 241) in the succession of superimposed sheets, as indicated in phantom lines in Figure 5.
As a result thereof the lowermost sheet 24a lacks support underneath its lug 26a so that its front portion will drop and disengage itself from the rear wall of partition 38 and its recess 39 which are arranged to terminate directly above roller 30, as shown in Figure 2. In consequence thereof the lowermost sheet 2411 is now free to slide forwardly over a distance determined by the dimensions of guide slots 35 which are of sufiicient length to permit the rear edge of the sheet to slip from carrier bar 27. Thus, sheet 24a has lost rear as well as front su port and will slide down onto the arcuate portions of guide rods 36 as far as cross bar 31 will permit, and until its front portion rests against inclined chute H5, or whatever sheet or sheets may previously have been released, as likewise shown in Figure 2.
As plate 24a drops onto chute I6 in the manner described, it causes the paper 25 placed thereon to slide off in forward direction and drop onto chute l6 which will conduct it to the delivery trough at the end thereof.
Reverting to the magazine, the lowermost sheet supports all the superimposed sheets 24b and 2411 respectively in the horizontal positions illustrated in Figure 2. As the roller 30 is withdrawn from underneath the front lug 26a of the lowermost plate and this plate drops onto the chute IS in the manner above explained, all the remaining plates and papers contained in the magazine will slide downwardly to a limited extent until thelaterally displaced front lug 26110! the next-lowest sheet 24b comes to rest upon roller 30 in'its new position of adjustment indicated in phantom lines in Figure 5. At the same time, therearward edge of said next-lowest sheet 241) will seat itself securely upon longitudinal carrier bar 21 due to the restraining effect of partition 38 and its recess 39 upon the front edges of sheet 24b and its forwardly projecting lug 26b respectively. Thus, there is no possibility whatsoever of any faulty operation such as might release more than one sheet 24, and deliver several papers for the price of one.
With sheet 24b securely positioned on roller 30 and carrier bar 21, conditions are established which are in all respects equivalent to those exis'ting'prior to operation of arm 34 and the machine is ready to serve another customer. will be understood that in order to deliver another paper, arm 34 will now have to be moved downwardly so as to turn bell crank lever 3| in counterclockwise direction, as viewed in Figure 5, and withdraw roller 3|! from underneath lug .-26b of what is now the lowermost sheet, institut- :-ing another cycle of operations like the one described above. It will also be understood that in practical use the described reciprocating movement of lever arm 34 will be effected by a suitable push-button mechanism of the coin-con-- trolled type which may be appropriately arranged laterally within the magazine, as indicated at 40 in phantom lines. Since the present invention is independent of any particular mechanism of this kind, a description of such a device has beenomitted. r
.;N t all the papers dispensed by the machine of my invention are stored in a horizontal position interiorly of the magazine 20. One copy is placed in vertical position in a chamber 4| formed between the front wall 41 of the magazine and a glass window 43 disposed before wall 42 to reveal the name, the date and the headlines of the paper to prospective buyers. Chamber-4| has a supply slot 44 on top to permit insertion of the paper, and is open at the bottom to communicate directly with the delivery chute I6 (Figure 2), except for a shelf or trap door 45 disposed underneath for the exhibited paper to rest upon.
Means are provided in accordance with my invention to dispense the paper within the chamber whenever the supply within the magazine 20 has been exhausted. For this purpose,- shelf 45 is hinged to the. lower-edg'eof front wall 42 anda latch 45 pivoted at 41 to the rear of front wall-42 is arranged to engage a rearwardly project ing lug 48 of shelf 45 to maintain said shelf trol stud 3!! incident to operation of the bell crank lever 3|. The last or uppermost sheet 24c; however, has a 1ug26c of a greater lateral width than any of the rightwardly positioned lugs 26a, as viewed in Figures and 6. Hence, as the last sheet 240 drops from control stud 30, its front lug 260 will strike tail 5| imparting counterclockwise movement to latch lever 46. as viewed in ill away from coin slot 52.
. 6 Figure 6. As a result thereof, the latch is'kicked away from lug 48 of shelf which'will instantly follow the urgency of spring 49 and swing into vertical position. In consequence thereof the last paper contained in the machine will drop out of chamber 4| and onto delivery chute i6, exposing some suitable lettering such as the words Empty or Sold out painted on the front wall 42 of the magazine behind the glass window 43. Thus, any potential purchaser is warned that the supply of the machine is exhausted. As an added safeguard, the trap door 45 may be arranged to operate a mechanism adapted to bar the coin slot 52 of the machine. For this purpose a suitable plate 53 is held above, and directly behind, the coin slot 52 by means of a link 54 disposed to rest upon trap door '45, as shown in Figure 8. Plate 53 is provided'with a suitable guide groove in the form of a vertical slot 55 arranged teengage a stationary guide surface, such as a recessed part of magazine wall 22, to constrain said plate 53 to vertical movement toward or As trap door 45 swings into vertical position to dispense the last paper contained in the machine, plate 53, devoid of any support, slides downwardly an appropriate distance determined by the vertical length of guide groove 55 to effectively close the coin slot 52. Thus, absent-minded customers, who may overlook the warning in window 43, are unable to place a coin into the machine. Care should be taken to so dimension the vertical length of guide slot 55 as to prevent the lower extremity of link 53 from descending below the bottom level of magazine 20, for this might cause entanglement with the front wall M of pedestal ID as the magazine is removed from the housing for replenishment.
It should also be noted that a heavy bar 55 is mounted on top of the uppermost sheet 240 to increase its weight and thus enable it to effectively initiate the various operations described above as it is released from control stud 39 and strikes againsttail 5| of latch lever 46. As an alternative, top sheet 240 may be made of greater thickness or of an appropriately heavier material than sheets 24a and b.
To replenish the machine of my invention, lid l9 is opened and the magazine 20 is turned over sothat its open rear end-faces upwardly. As a first stepthe carrier bar 21; is swung out of arcuate slots 29fso that sheets 24 maybe conven iently passed to positions above control stud 30,
whereupon bar 21 is returned to, its} original pos'ition, care being taken thatits ends are pushed fully into arcuate slots 29. Then, newspapers are inserted between eachtwo adjacent.sheets;24.' as shown? in Figure 2.1 To facili separation of the sheets, arcuaterec'esses 51-, may be provided in the rear edges-thereof, as shown in Figures 3 and}, and the recesses of "consecutive sheets are preferably arranged in steps displaced by about half their diametrical width. The recesses 51 are of particular advantage in removing obsolete papers that have not been sold. Now, link 54 is lifted to raise locking plate 53 above coin slot 52 and t i i, ap door 45 at the bottom of chamber 4| is f ecocked by latching its lug 48 under lever 45. Finally, a last copy of the paper is inserted into chamber 4| through supply slot 44 and the magazine is placed, in its proper upright position, into the window formed in pedestal I0, whereupon lid I9 is lowered and locked down, and the machine is ready to serve the public. v
t he e sar The detachability of the magazine unit 20 is of particular convenience in servicing a large number of machines located in widely separated places. For instance, if the newspaper supply is furnished in a truck, as is frequently the case, an employee may fill magazines with papers While the truck is in motion travelling from machine to machine. Thus, whenever a machine needs replenishing, the service man merely removes the empty magazine from the machine and substitutes a filled one instead, which takes less than a minute, and by the time the truck reaches another machine he has provided the empty magazine with a fresh supply, so that it may be exchanged for the exhausted magazine of the new machine.
In many instances it will be advisable to replenish a machine, even if its supply has not been exhausted but has merely run low. Means are, therefore, provided in accordance with my invention, to exteriorly indicate the approximate number of papers left in the interior of the magazine, so that a service man may know at a glance whether a machine needs replenishing, even if the supply has not been exhausted to such an extent as to expose the warning word Empty."
For this purpose rollers or pulleys 58 and 59 are rotatably mounted at the top and at the bottom of the side wall 2| of the magazine 20, as shown in Figure 7. Trained around pulleys 58 and 59 is an endless chain or cord 60 in which are knotted a plurality of ec ui-spaced beads or markers 5! arranged in two sequential series of distinctly different colors. As shown in Figure 7, cord 66 has a front run extending vertically through chamber 4| at a place to the left of the paper exposed through window 43, and also a rearward run extending at the back of magazine wall 42 and firmly anchored in a lug 82 projecting from the front edge of the last or uppermost sheet 240, as shown in Figure 3. Thus, as the top sheet 240 slides to lower and lower levels within the magazine 20 as the machine dispenses one paper after another, it pulls the rearward run of the cord 60 in downward direction, imparting counterclockwise movement to the cord around its pulleys 58 and 59, as viewed in Figure 7. The number of beads or markers 6i knotted into cord 60 is preferably twice as large as the number of papers that may be stored in the magazine 20. One-half of these markers may be painted white, and is arranged to be visible through the window 39 when the magazine is loaded to full capacity and the top sheet 240 is at its highest level; the other half of the beads or markers El may be painted red, and is arranged to extend below and rearwardly from said first half.
Thus, as the supply of papers in the magazine diminishes, the counterclockwise movement imparted to endless cord 66 by top sheet 240 will cause white beads to disappear over pulley 59 and out of the vision of the window 43, while a corresponding number of red beads will rise into the vision of the window from below. Therefore, as a supply truck approaches a machine, the service man is able to tell at a glance to what extent the supply in the magazine is exhausted, and whether the magazine should be exchanged or not.
The described machine may be used for dispensing articles of varying thickness, such as the Sunday and week day issues of newspapers, without requiring any adjustment whatsoever and Without the slightest eifect upon its dependability of operation. The machine is of a very simple construction and its performance does not depend upon high precision finish of any of its components nor are any of said components required to perform high precision operations. The machine may, therefore, easily be manufactured in large quantities and at such low cost as to permit profitable use thereof in locations of small turnovers, and in fact in all those places all over the country which depend for proper payment almost exclusively upon the honesty of the purchasers.
Furthermore. the manipulation of the machine is of the simplest nature and will, as a rule, require no more than the pressing of a push button, whereupon it will dependably dispense one paper at a time, with no possibility for the customer to foul up the machine by inappropriate manipulation, or for the machine to disorganize its mechanism by accidental release of more than one paper. In fact the construction of the described machine is such that it is absolutely impossible for the individual papers to adhere or to be released from the magazine other than individually.
While I have explained my invention with the aid of a preferred embodiment thereof, I do not wish to be limited to the constructional details shown and described, because other embodiments based on the same principles and combining the same dependability of performance with simplicity of construction may readily be devised by those skilled in the art Without departing from the s ope of my invention.
