To all whom z'tfmay concern Be it known that I, ALBERT D. GROVER, a citizen of the United States, and a resident of New York city, New York, have invented certain new and useful Improvements in Vending-Machines, of which the following is a specification.
. My invention relates to vending machines and has for its object in general the provision of a machine particularly adapted for use in locations where space is very limitedas for instance in street cars or railway cars, where it can be readily attached to the wall or posts between the windows. In other words, the machine of my invention is designed to take up as little room as possible and will not project suiiiciently from its support to be considered an obstruction. In a machine which I have actually constructed in accordance with the invention herein disclosed, the depth of the machine casing was about three fourthsV of an inch, and the width about two and one half inches. The height of course will depend upon the number of packages (such as chewing gum, candy and the like) which the magazine shall contain. v
In order to reduce the depth of the machine to a minimum, I provide a magazine adapted to contain the vendible articles edge upon edge in a vertical column which rests upon an adjustable supporting mechanism operable to releasethe articles one by one. In the broad aspect of my invention, this supporting mechanism has upper and lower supporting portions movable with respect to each other, so vthat before one portion can pass fully into releasing position, the other portion reaches a supporting position. lThis absolutely insures the release of the articles one by one.y With this supporting mechanism, no separate ejecting device is necessary, which adds greatly to the coinpactness of the machine.
More specifically considered, my new form of supporting and releasing mechanism comprises two pairs of oppositely arranged levers at the lower end of the magazine. Normally, thecolumn of articles rests upon the two lower levers. rEhese are so connected with the upper levers that before the lower levers mcve out of support-ing position, the
upper levers engagethe column of articles above the iowermost article and support the entire column as long as the lower levers' are in releasing position. Not until the lowery lslide which is verticallyV movable and operated from the outside of the machine by any suitable means-such as a knob or wheel. rIhisslide is normally locked against Vfull movement, but is unlocked through the medium of the deposited coin. When the last package has been discharged from the magazine, the slide is automatically locked in its lowermost position to prevent the insertion of a coin into the machine. The above and other objectsV and advantages of my invention will become apparent from a detailed description of the drawings which show a machine embodying the various features of my invention in a form now best known to me. In these drawings, Figure l, is a front view of the machine, with the front wall of thecasing broken away in order to expose the interior mechanism to view.; Y f
Y Fig. 2, is a longitudinal section on line 2 2 of Fig. l. j
Fig. 3, shows a viewy similar to Fig.' 1,
with the coin slide and the supporting mechanism in operated position. Fig. 4, shows a horizontal section sub stantially on line 4-4 of Fig. l. v
Fig. 5, is avertical detailed section on lineof Fig. 3, showing the coin slide in locked position when the magazine is empty and 'Fig 6 is a'vertical detailed section 'of aV formed kof twosections-a rear section comprising a rplate land a front section comprisingthe front wall 2, sides 3 Vand 4, top 5 and bottom 6. The twosectionsare secured together in any convenient way. In the drawings I have shownthe back plate 1V provided with side iianges 7- for receiving the sides 3and24, as shown Fig.' 4, `,and
with a bottom flange 8 which provides a recess 9 for receiving the flange .10 on Vthe bottom plate 6. The front section of the casing is held locked against the back plate s Vmachine is adapted to be secured in place on any desired supportcarri es the lmagazine containing the vendible articles. This inagazine may be conveniently formed of a pair of sheet metal bars 15, having rear flanges 16 for receiving suitable fastening devices, and
front flanges 17 for retaining the packages within the magazine. As seen from Figs. 2 andA 1, the depth of the magazine is very slight, so as toretain the articles or packages P` edge upon edge in a vertical column. These packages P may contain any suitable CQIlfeotions-such as chewing gum or candy. The heightk of the machine would vary in accordance with the capacity of the magazine. I yhave provideda novel mechanism for supporting the packages in the'magazi'ne and releasing them one `by one, without danger ofmore than one package being released at each operation ofthe machine. Broadly speaking, this mechanism has two separate and distinctive engaging portions, one for supporting packages when the mechanism is in normal position, and the other for supporting the packages when the mechanism is 1n operated position. These eiigaging portions are movable relatively to each other, so that one portion passes into engagying position before the other portion reaches a releasingpositio'n. In this way the'col'- umn of packages is never without a positive support. Referring now in detail to the spe ific form vof supporting and`V releasing mechanism shown iii thej drawings, it will be seenthat I have provided a pair` of lower levers 18v and a pair of upper levers 19. lEach VLpair of levers 18 and 19 is pivotally mounted on a pin ory stud 20 carried by the .back plate 1. The twor pairs Vof levers are mounted upon oppositesides of the package magazine atY the lower end thereof,
and are so arranged that when the levers 18 are in norma-l position, the lowermost pack- Y age P rests at its ends directly upon the supyso porting lugs 21 which'V .f project inwardly' from' the levers-18. These levers areheld in 4normal, position by spring blades 22 secured kto the sides of the casing at23 and Vadapted attheirvfree ends tobear ragainst the pins A24e projecting laterally Afrom the :levers 18.
Any. Y other .suitable arrangement may of coursebe provided for-holdingthe levers 18 in normal position. Th'eup'per levers 19 are yieldably connected with their vrespeck tive ,llwer levers 18 by means `of springs 25.
The upper end of each 'of these springs is ccnnected toV the upper lever I 1-9 and the lower end to the lower lever 18, while the intermediate portion of the spring is coiled about the pivoted stud 20. The connection Vof the springs 25 is to hold the levers eX- in the slots 27 formed in the upper levers 1.9.
At their free ends, the levers 19 are' provided with pointed projections 28. The connection between the levers18 and 19 is such that when the levers 18 are in supporting position, the pointed projections 28 on the levers 19 are out of the magazine. However, when the levers 18 are moved outwardly (by means to be presently described) into releasing position, the levers 19 are rocked inwardly and the pointed projections 28 enter the magazine and pierce the sides of the package above the lowermost one suiiiciently to support that package and all the packages above it. Fig. 3 clearly shows the levers 18 and 19 in operated position. The movement ofthe levers 18 and 19 with respect to each other is so timed, that before the supporting lugs 21 of the levers 18 have moved out of contact with the lowermost package, the pointed projections 28 on the levers 19 have iirmly engaged the package above the lowermost one, and thus support the entire column while the released package falls ontA of the magazine, through the delivery-chute 29 into the pocket or deliveryopening 30. In Figs. 1 and 2, the delivered package is shown at P1. To enable the package to be readily grasped by the patron, the front wall of the casing is cut away at 3l and 32. It will be noticed that the packages are delivered end-on. The chute 29 and the delivery-pocket 30 are formed by a partition 33 suitably secured to the front section of the casing. Vhen the springs 22 return the levers 19 to normal position, the levers 18 remain in operated or retaining position until the pins 26 strike the outer ends of the slots 27.Y Vhen this occurs, however, the lugs 21 of the lower levers 18 havey already moved into supporting position, so that when the continued movement of tlielevers 18 rocks the levers 19 out of retaining position, the released column of packages drops on to the lugs 21. By this `means it is impossible for more than one my new form of supporting and releasing mechanism, the relative movement of the levers 18 and 19 always insures the'movement of the upper levers 19 into supporting position before the lower levers 18 reach a releasing position, and vice versa. Broadly speaking, the leversj18, either or both of them, may be properly considered as a support or supporting device which normally supports the column of articles within the magazine, while the levers 19, either or both, may be considered as yieldable means controlled by the levers 18 to sustain the column of articles in the magazine when the support is moved or adjusted into releasing position.
The levers 18 are moved outwardly into releasing position by means of the coin slide 34 which is mounted in the front section of the easing for vertical'reciprocation The lower corners of the coin-slide 34 are beveled, as shown at 35. The slide 34 with its beveled or cam portions 35 may as a whole be considered as a cam device which operates the supports 18 and 19. From the lugs 21 on the levers 18 project forwardly the extensions 36 which are arranged to be engaged by the beveled portions 35 of the coin-slide as the latter is moved downwardly. In this way the levers 18 are rocked outwardly from supporting into releasing position upon a complete downward movement of the coin-slide 34. This slide is guided in its movement by the plate 37 suitably secured to the front wall of vthe casing.
Complete downward movement of thecoinslide 34 is normally prevented by the pins 38 carried at the upper ends of the two levers 39 which are pivoted on pins 40 secured to the guide plate 37. The pins 38 are at their outer ends semi-cylindrical, as clearly shown in Fig. l, and project into the slots 41 formed in the' coin-slide 34 on opposite sides of the projection 42. The
. coin-slide is also provided with a downwardly extending projection 43 having a curved recess 44 which coperates with the curved end 45 of the projection 42 to form the opening 46 for receiving the deposited coin. On either side of the recess .44, are provided stop shoulders 47 which are arranged toencounter the pins 38 as the slide is pushed down. The levers 39 are held inwardly by the springs 48 secured at their upper. ends-to lugs 49 vmounted on the .front section of the casing. Stops 50 are arranged to limit the inward movement of the levers 39. .The normally free movement of the coin-slide 34 is insufficient kto bring the beveled corners 35 into engagement with the extensions 36 on theY levers 18. However, when a proper coin is deposited in the coinlreceiving opening 45, and the coin-,slide is thereupon operated downwardly (through connections to be presently described), the
coin engages the pins 38 and forces them outwardly into vertical alinement with the 'slots 51 formed at either side of the provjection 43. W'ith the pins 38 in this posicoin-slide to have full ejecting movement.
As already described, when the coin-slide is moved downwardly to its fullest extent, the
beveled corners 35 engage the extensions 36 of the goods-supporting levers 18 and force the same apart outwardly to release the lowermost package which falls into the pocket 30 through the chute 29.- The Jfront plate 2 of the machine casing is provided with a coin-entrance opening 52 which registers with the coin-receiving opening 46 on the coin-slide 34 when the latter is in normal position.
It should be noted that the coin-engaging pins 38 also serve as a coin-testing device. For instance, if the deposited coin is of insuiicient diameter, the pins 38 will not be forced outwardly a suiicient amount to clear the shoulders 47. Should the deposit-ed ycheck be of soft or yieldable material, such as lead, paper and the'li'ke,'the edges ofthe semi-cylindrical pins 38 will bite into the material or' the check and thereby act as a positive stop against the further downward movement of the coin-slide.
Preferably, the opening 52 is surrounded by an inwardly extending fiange 53 which cooperates with the fixed plate 37 to guide the coin-slide 34 in its movement.
The coin-slide 34 has rigidly attached thereto a rack 54 arranged to mesh with the pinion 55- fixed to the inner end of the stub shaft 56. This shaft projects to the outside of the machine through an opening in the front panel 2 and is at its outer end provided with Va suitable hand-operated membersuch as a wheel-or knob 5,7. It is evident that when the knob 57 is rotated in a clockwise direction, the coin-slide`34 is moved downwardly through the rackand pinion connectionfjust described. Fig. y'1 shows the coin slide in upper or normal posi'- tion,while Fig. 3 shows the same inilowermost or operated position. The coin-slide is returned to normal position lby suitable spring means-such as a contractile spring 58 which is secured to the coineslide vat 59 and to the casing at 60. A
yOn top of the column of goods in the magazine rests a weight'61 provided with a pair of beveled projections 62, as best shown in Fig. 4. Really only one projection would Y 37 is at its lower end provided with a recess 63 from lwhich extends yupwardly the slot 64. This slot and recess serve to accommodate the dog 65 which is pivoted on the pin 66 carried by the 'guide plate 37 at the recess 63. kA spring 67 coiled about the pin or stud 66, engages at its upper end the pin 66 carried' by the dog'65 and at its lower end bears against the guide plate 37 to hold the dog 65 normallyin backward position, as shown inFig. 2. At its free end, the dog 65 is provided` with a projection 69 having an upwardly extending point 70. This point is adapted to engage the beveled upper end 71 of the slot 64 to limit the rearward movement of the .dog 65 under the influence of the spring 67. When the last piece of goods drops out of the magazine, one of the projections 62 on the weight 61 comes in contact with thedog 65 and forces the same forwardly into the positionshown in Fig. 5. Itshould be understood thatl this forward movement ofthe dog 65 takes place to inform the patron ofV that fact.
when the coin-slide 34 is in lowermost position, so that the nose or projection 69 of the dog engages the shoulder 72 on the coinslide. This positively locks the coin-slide in lower-most position, and prevents the deposition of fl'lrther coins into the machine. Preferably, thecoin-slide carries a suitable sign or mark such asfthe word Empty which registerswith thecoin-,opening 52 cf the front plate when theimachine is empty,
To unlock the coin-slide, lit Vis/necessary to remove the front section of the machine and restore the dog 65 to normal position by hand, whereupon the coin-slide is drawn upwardly Ainto normal position by the spring 58.
After the magazine has been filled with the vdesired goods, the weight 6l is placed on top of the packages, and the front section of the casing locked in place again, whereupon the machine is ready for operation as before. kThe weight 61 is at its sides provided with grooves 73 toaccommodate the points 28 .of the levers 19.
In orderto preventthe machine from being operated kby washers, kI provide a pawl 74 pivotedat 75 tothe guide plate 37 and provided atits lower end with a forwardly projecting hook 76 arranged to extend through the openingv 77 in the guide plate.
- A leaf spring 78, Xed to theguide plate 37 at the points 7 9, bears at its lower end against the shoulder 8O formed at the upper end of thepawl 74, to force lthehook 76 forwardly@ The .pawl 474 is pivotedxsubstantially midway vof the guide plate 37, as best shown in Fig, 4, and is readily accommo- .dated in the space between the guide plate andk themagazine. p When' a washeris deposited in the coin-receivingopening 46 and the knob '57 .rotated tomove the coin-slide 34 downwardly, the' hook 76 of the pawl 74 enters the opening in the washer before the slide is moved downwardly any great extent, and thereby positively locks the slide against further downward movement. Fig. 6, shows how the hook 76 of the pawl 74 has entered the opening in the washer 81. Ihen the knob 57 is released, the coin-slide 34 is carried back to its normal position, together with the deposited washer. This movement is permitted by reason of the fact that the hook 76 is beveled at the bottom, so that it is cammed rearwardly by the washer during the return movement of the coin-slide. The washer is therefore carried back to the coinopening where it can be removed.
The pawl 74 serves another purpose, and
lthat is to eject the coin from the coin-slide forced out of the coin-slot 46 by'the hook 7 6A and drops into the cash box 83. This ejection of the coin by the pawl 7 4 does not take place until after the pins 38 have entered the slots 51 in the coin-slide 34.
' The operation of my new machine will be clearly understood from the foregoing detailed description, and it is not therefore believed necessary to repeat the same. Although I have described one specific form of machine embodying the various features of my invention, I would have it understood that I d0 not intend to be limited to the details of construction set forth, as it is obvious that various changes and modifications may be made without departing from the scope of the invention as defined in the appended claims.
