'2,889,074 Pintented June 2, 1959 A pair of oppositely disposed `parallel longitudinally extending elements 24 and 26 are suitably secured to opposite inner sidewall portions ofthe side walls 20 and 22, and 'support thereupon pairs of longitudinally spaced elongated support ystrip elements 28. Each of the support `strips ZShasntermediately secured `thereon a pair of spaced upwardly extending elongated strip` elements 30 supported in any suitable manner, the strip elements 30 dening a pluralityof longitudinally extending linearly related bottle` magazines `including a forward bottle magazine 32 and ysucceeding"intermediate bottle magazines 34, and a `rearbottle magazine 36; Each of the pairs of vertical 'support strips 30, with the exception of the forwardmost 'str'ips`30", (see Fig; l), include an upper transverse support shaft 38 having xedly secured thereto in any-'suitable manner adownwardly depending leaf spring member 4i) with its lower extremity extending below the axis of oscillation of artransverse pivot shaft 42 which cxtends transverselyibetween the various pairs of support elementsi) being `retained ina substantially fixedV posi` tion by meansof suitable collar elements 44 secured on said shaft 42, said sh'aft'having integrally secured and rotatable therewith an enlarged `-spring engaging portion 46 engageable with the leaf spring 40, said sprin'g en'- gaging portion 46"terminating in an elongated bottle engaging element 48 which is normally urged "by the springV element `or rod 46into the bottle magazine forward thereof as seenin forward bottle magazine 32 in Figure l, for" example, and which is retained in a rearward position by the bottles 50as`rseen in the rear bottle magazine 36, for example.

The shaft 4Z extends through the side wall 20 and ter-pv minates in right angularly related end portion 5'2 depend-A ing substantially parallel to the side wall 20, said portion or dog 52 terminating in a lower rearwardly opening notch portion 54. Pivotally supported and depending at rearwardly spaced relationship from each of the portions SZof the shaft 42 by L-shaped latch lever elements or bell cranks 56`which `include one leg S8 secured by means of a suitable pivot element 60, said leg 5S having a distal end portion 62 engageable in the rearwardly disposed notch 54 of the shaft portion 52, see Fig. 7 for example, the otherend 64'of the lever S6 being pivotally connected by means of a `suitable pivot element 66 to an elongated leve'r elementor link `68, said lever element 68' including an elongated lost motion slot 70 at the en'd opposite that and which is pivoted to the pivot element 66;

Extending transversely beneaththe strip elements 30 andthrough oppositely aligned apertured portions in the strip elements 24 and 26 are support shafts `72. which may be secured in place by means of suitable collar elements 7 4 secured thereon, see Fig. 3, said shaft 72 having xedly secured thereon a radially extending` elongated transverse bottle stop plate 76 which normally extends in engage-` It will be noted in Figure 2, that a lateral abutment ele-` ment 57 is secured in any suitable manner on the side wall in the path of rotation of the leg 58 thereof for preventing excessive counter-clockwise rotation of the forwardmostL-shaped Vlatch lever element 56 when the forward bottle magazine 32 is loaded or has bottles contained therein. i

It will be noted in Figures l and 2 that a stop plate 76" is provided beneath the forwardmost bottle magazine- 32. The purpose of this stop plate 76 is to tend to direct the bottles dispensed from the forward magazine toward the forwardmost strips 30', and to prevent a succeeding bottle from jamming between' a bottle dispensed from the magazine 32 and the conveyor passing therebeneath the stop plate 76" cooperates with a support shaft 72, lever element 56 and elongated lever 68 and arm 80, however, no pivot shaft 42 with the end portion 52 will be utilized therewith. Since the bottles from magazine 32 will be free to be immediately dispensed when the apparatus is actuated in a manner to subsequently become apparent.

When the bottles are emptied from the forwardmost bottle magazines 32 and 34, the lever elements 48 will have pivoted forwardly or to the left, this movement results in an accompanying forward movement of the rod portion 52, see Figs. 7 through 9, swinging the notch portion 54 away from the distal end 62 of the leg 58 of the L-shaped lever 56 whereupon the weight of the bottles on the next succeeding bottle magazine and the stop76 therebeneath will be moved downwardly into the position shown in Figure 8, and when the bottle magazine succeeding the one iust mentioned is permitted to dispense bottles in the manner heretofore described, the stop element 76 will assume the position shown in Figure 9 by virtue of the passing of bottles from the rear portion of the dispensing mechanism forward on the conveyor assembly 84 and onto a bottle chute assembly 86 to be subsequently described.

Thus it will be apparent that each of the bottle magazines progressing from the forward magazine 32 to the intermediate magazines 34 will be automatically emptied through the actuation of the heretofore described structure, and after the next to last intermediate bottle magazine 34 has been emptied the shaft portion S2' thereof, see Fig. 2, cooperates with the lever element 88 intermediately pivoted at 90 and having one end portion 92 lockingly engageable with the notch portion 54' of the shaft end 52', the other end of the lever element 88 being secured to one end of a tension spring element 94 which has its other end suitably and fixedly secured at 96 on the side wall 20. Pivotally secured at 98 at the same end of the lever 88 as the spring 94 is secured is a depending rod element 100 which is pivotally secured to the shaft 72 of the transverse stop member 76', see Fig. l, of the rear most bottle magazine 36, said shaft 72' being fixedly secured to a link element 80 pivotally secured at 82' on the side wall 20. The bottles in the magazine 36 will each individually be of a sufficient weight to overcome the tension spring 94, and said tension spring 94 will be of sufficient strength to pull the lever 88 back into the position shown in Figure 2 when the machine is empty, thus preparing the dispensing mechanism for reloading and subsequent movement of the shaft portion 52 into an overlying locking engagement with the end portion 92 of the lever 88.

The conveyor assembly 88 comprises forward and rear shaft members 102 and 104 extending transversely between opposite portions of the side walls 20 and 22 being secured thereon by means of suitable collar elements 106, the shafts having secured `thereon transversely spaced sprockets 108 rotatable with said shafts and having journaled thereon endless link chain members 110, of any suitable character, which have extending therebetween in suitable spaced relationship for receiving the bottles 50, see Fig. l, a plurality of shafts 112 which carry thereon roller elements 114, said roller elements being of any suitable material such as rubber, wood, etc.

The shaft 102, see Fig. 2, is connected by means of a suitable transmission case 116 to any conventional power means such as an electric motor 118 which is driven by a suitable source of electrical energy 120, said motor 118 being normally operated by a coin actuated switch 122, see Fig. 10.

A vertically extending support plate 124 is suitably secured in parallel spaced relationship to the side wall 22, and includes an upwardly extending intermediate pivot portion 126 pivotally supporting on a suitable pivot element 128 a switch actuating lever 130 which normally has its end 132 extending in the line of movement of the conveyor assembly 84, whereby the bottles 50 will engage a horizontal flange portion 134 thereof, see Fig. 3, the weight of the bottles 50 being sufficient to urge the end portion 132 downwardly raising the opposite or shorter end portion 136 upwardly whereby a suitable bracket element 138 on the end 136 will be urged out of engagement with a micro switch element 140, of any suitable character, said switch 140 normally being closed and in the position shown in Figure l, and being opened as shown in the position of Figure 4. The switch as shown in Fig. 4 is open by virtue of a U-shaped spring element 142 having a lower leg 144 secured in any suitable manner on the bottom 18 of the casing, the upper leg 146 thereof engaging the underside of the switch actuating lever 130, and being strong enough to urge the lever into a switch opening position as shown in Fig. 4 when the bottles 50 are no longer in engagement with the end portion 132 of the lever.

Thus when the switch 140, see Fig. 10, is urged to an open position, although a coin actuates the switch mechanism 122, current cannot ow in the circuit to the motor 118 and accordingly the conveyor assembly 84 will not be operated.

The chute assembly 86 includes a support bracket 148 suitably secured by means of a web portion by means of suitable fasteners 152, and includes a pair of oppositely disposed pivot support leg members 154 and 156 extending horizontally forward of the roller members 114 of the conveyor assembly 84, and supporting therebetween on a suitable pivot pin 158 a substantially balanced chute element 160 having a bottle receiving portion 162 at one end, and a substantially weighted portion 164 at the other end, the chute 160 being pivotal about the pin 15S, see Figs. 5 and 6, and operative to engage a suitable micro switch 166, of any suitable character, Which is actuated when the dispensing assembly assumes the position shown by the phantom lines of Fig. 5, and accordingly the switch 166 is also operative to open the circuit shown in Figure l0 whereby the conveyor assembly 84 will not be operated by the motor 118 until another coin is utilized for actuating the ycoin actuated switch 122.

As shown in Figure 10 the circuit containing source 120 and motor 118 is rendered operative upon closing the normally open, coin actuated switch 122. If switches 120 and 166 are in the closed position, the motor 118 will be energized. However, during the functioning of the bottle dispensing mechanism, when either or both of switches 140 and 166 become opened, by actuating levers 130 or 160, the circuit is immediately interrupted and opens so that the motor can no longer function.

Various positions or directional terms such as front, rear, top, bottom, etc. are utilized here and have only a relative connotation to aid in describing the device and are not intended to require any particular orientation with respect to any external elements.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling Within the scope of the invention as claimed.
