SELECTIVE VENDNG MACHINE.

Application led August 5, 1925.

rllhe present invention relates to selective vending machines and pertains more particularly to the fully selective type of ma chine invented by the undersigned and set forth in our co-pending application Serial Number QQAOS.

Our present invention has among its objects the provision of a machine in Which the articles are more easily selected and in Which the contents of the machine may be learned Without the necessity of operating the parts. Incidentally it is another object of the invention to incerase sales by a'tractively displaying the Wares to be vended by the ma chine.

Another object of the invention is to provide a selective vending machine adapted to handle and vend a wide variety of shapes, sizes and brands of articles, including articles varying in size and nature from sandwiches and individual pies to irregular shaped candy bars and the like. Given quantities of loose articles are even contemplated for vending, together With articles of standard shapes and sizes.

Another object of the invention is to hold all articles against movement and vibration, so that the article holders are moved in the act of selecting an article, the contents of the machine are not moved in their respective holders.

Another and important object of the invention is to provide for efficiently holding, as Well as properly ejecting, varied sizes of articles Without subjecting the article to be vended to impact from a manually controlled or automatic ejector.

Another object of the invention is to thoroughly enclose and protect the articles to be vended against insects and the infiltration of dust and the like, and against damago by objects sometimes employed in attempts to rob the machine.

Another object of the invention is to provide improved article holding and ejecting means suitable to a Wide variety of vending machines, both selective and otherwise.

Our invention contemplates the use of indivi dual compartments or-holders for containing` the article or articles to be vended in Serial No. 48,274.

exchange for a coin. It is further contemplated to insert and remove the articles thru a closure which is adapted to be moved to closed position to retain and protect the contents. It is therefore among the objects of the invention to provide a` machine embody-- ing a large number of such compartments Without the necessity of employing more than one coin controlled mechanism for effecting discharge of the contents of any selected holder.

lt Will be understood, in the consideration of the invention, that it is very expensive and impractical to employ a plurality of coin controlled mechanisms in one machine. In fact, in order to provide against operation by slugs and other trick devices, the requisite coin controlled mechanism is expensive enough. It is therefore an object of the invention to provide for controlling a large number of individual article holders With one coin controlled device, While providing separate closure for each and every article holder; all Without undue cost.

Another object of the invention is to provide a machine which is easily replenished, attractive, sanitary, and Which vvill provide more protection to both operator and the patron against mistakes and loss of money.

Another object of the invention is to provide means whereby gravity need not be depended upon to bring the purchased article into the hands of the patron, particularly Where the object is of such character as to tend to lodge in the discharge chute.

Still other objects and advantages of our invention will appear hereinafter and Will be better understood because of the order in which they appear.

We have illustrated our invention by the accompanying drawings in which We have shown one practical embodiment of our invention, also a slight modification thereof; it being understood that the embodiment and modification shown are merely typical of our invention, and are by no means representative of the Wide variety of applications to Which the various features of our invention are adapted. The drawings, together With the ensuing description, will enable those skilled in the art to maire and use the embodiments illustrated and described, and to further apply the various Yfeatures to other vending machines and to conceive and con struct numerous other embodiments employing our invention.

1n carrying out the invention in the embodiment shown we provide front and rear casing walls, 15 and 16 respectively, connected by a peripheral wall 17, to provide a substantially inaccessible interior space 13. The casing is provided forwardly with a coaxial opening 15a covered by a window 15b, so that certain hereinafter described parts are visible from points exterior to the casing.

lNithin the space 13 there is provided a plurality of article holders 19, adapted to contain any suitable article .or articles such as a boxed sandwich 20, an irregular shaped candy bar 20', or two or more small objects such as 21, loose articles in large quantities may also be held in the article holder shown.

Each article holder is provided with a hinged closure generallyindicated by the numeral 22. ln the embodiment shown said closure is divided into two parts, 22a and 22b respectively. Each is hinged to a corresponding side wall 23, of the holder, by a hinge such as 2li. Means, to be described hereinafter, are provided for holding' the closure locked in closed position, and other means are provided for effecting the .opening of a closure only as a result of introducing a coin to the machine. y

The casing is provided with a discharge opening 25, provided in the peripheral wall, and it is among the purposes of the machine, and mechanism about to be described, for causing the contents ot any selected one of the article holders, to pass into and thru the discharge opening, upon introduction of a coin and proper operation of coin controlled parts.

ln the embodiment illustrated, the discharge opening and the chute 26, which leads outwardly therefrom, is hxed, while the article holders are collectively movable; the purpose being to bring any selected one 01 the article holders into discharging registration with the chute, and to there eii'ect opening of the closure to release the contents.

The article holder shown in Figs. particularly, includes end walls 27 respectively, and a bottom wall 29. rFhru the bottoni wall extends a guide stem 30, which carries on its inner end a movable wall 31, arranged to travel in the interior of the holder. Between the bottom wall and the movable wall a spring 31"L is inserted which tends to impel the movable wall outwardly.

Gbviously each spring will act to hold the corresponding movable wall against the con tained article and said article in turn is held against the closure; thus the article is held from movement and vibration, and the closure tits closely enough to enclose the article against foreign matter and to protect it from any objects that might be employed te damage or rob the machine. lt will also be seen that when the closure is opened the spring will act to 'force the contents outwardly without striking a blow. Rapid but careful and positive delivery of the contents of a holder is thereby assured.

The closure members are connected by links 32, to a retract-ile bolt 33, which slidable along one ot the end walls et the holder. Said bolt has a right angle bend providing an extension A bridge or yolre 35 passes over the bolt to guide same in its movements. A spring is connected at one end to the yoke and at the other end to the extension 34 oi the bolt. The tendency et the spring is to draw the extension toward the yoke so that the lower part et the bolt will move outwardly to carry the linlrs and closures into open position, as shown in Fig. 3 particularly.

To hold the closure members in closed position, against the urge of springs 3G, there is provided a latch 37. Said latch is riveted to the holder as at 33 while the remaining portions are tree to be bent outwardly away from the holder. The metal employed in. making the latch should have spring characteristics. rllhe latch includes an outwardly directed oblique portion or surface 39. Said latch also includes a step d0 adapted to engage the extension 34 on the bolt, when said bolt is in fully retracted, closed position. rThe spring characteristic et the latch holds the step in locking engagement with the cX- tension 34 et the bolt, and thus the latch. will hold the closures indeiinitely against the urge of any contained article. @bviously, a member such as 41, engaging the llO surface 39 and moving parallel with the adjacent vertical wall of the holder, will act on the oblique surface of an operatively registered holder to move the latch outwardly and so release the bolt. Member 4l is here inafter known as the coin controlled member, or coin controlled latch releasing member. Other parts about to be described associated therewith are known, together with the said member, as the coin controlled means.

The article holders are each riveted as at 42, to a face plate 43. Said plate is in turn carried by a sleeve 44 which turns on the axle. The sleeve, plate, and assembly of article holders are collectively known as the magazine; the individual article holders serving to provide a revolvable magazine having a plurality of pockets, each fitted with a hinged closure. The magazine may be constructed as a single piece in which the pockets are provided as required. rlhe end walls of the holders, which are opposed to the walls which carry the latches, are each provided with an opening 45, thru which the contents of the holder may be seen. lVhen required for loose or irregular shaped articles, said openings may each be fitted with a translucent sheet (not shown) of glass, Celluloid or the like. A rear extension to the chute extends upwardly as at 48, so that the latch of the adjacent closure cannot be reached thru the chute.

The article holders, in the embodiment illustrated, are each designated respectively by numerals, in this case, l to 30 inclusive. ln front of the outer end of the axle, just behind the glass, there is provided a menu card holder 46, havin@` a depending arrow shaped end pointing downwardly to the chute. l/Vhen the nature of the articles or packages being vended is such that their contents cannot be determined by looking thru the openings in the article holders, the menu-card may be consulted. The menucard designates the article wanted by a numeral. The magazine is then turned until that numeral is just below the point of the arrow. holder, containing the designated article, is in operative registration with the chute and the latch releasing member.

To selectively position the article holders there is provided a handle 49, externally of the casing which is connected to a shaft 50, said shaft extends into the interior of the casing and carries a small pulley 5l. The sleeve of the magazine is provided with a larger pulley 52, fixed thereto. A belt 53 connects the respective pulleys so that turning of the exterior selecting handle will slowly turn the magazine.

It is to be understood that the magazine is freely revolvable regardless of whether or not a coin is placed in the machine and lhen so positioned the article it is even possible to rotate the magazine in either direction so that the selected article may be brought into registration with the chute by the shortest route. Suitable means, not shown, may be provided for imposing slight resistance to the magazine so that when the magazine and contents is unbalanced it will tend to remain wherever it is set by the selecting handle. The handle preferably is arranged to drive the magazine thru the friction belt shown so that when the latch releasing means is in operation accidental turning of the selecting handle may cause the belt to slip without turning the handle. For reasons apparent hereinafter, the magazine is held locked while the latch releasingl member is in other than normal inoperative position.

Any suitable coin controlled means may be employed for moving the latch releasing member, but in the embodiment shown we provide a particular means which we will new describe. Said means includes a horizontal, oscillatable shaft 55, extending forwardly thru the casing and terminating in an operating lever externally of the casing. Said lever extends thru the frame and is fitted at the rear end with a coin engaging oscillatable segment 57. Said segment is pro ided with a step 58, terminating in a horizontally disposed foot 59. Normally the segment 57 is free to be oscillated without interference, but produces no result unless a coin, such as 60, rests on the foot.

The coin controlled means further includes another oscillatable segment in juntaposition to the first named segment. Said segment is provided with an integral'sl'eeve 6l, which fits loosely around the shaft A bearing 62 is carried by the frame, in which bearing the sleeve 6l is freely oseillatable. Thus the bearing supports the sleeve 6l, and said sleeve in turn acts as a bearing for the shaft. There is provided an L shaped arm 62, which is shown here as being integral with the sleeve. Said arm terminates in the vertically disposed, vertically movable latch releasing member.

T he machine includes a suitable coin chute 63, here shown as being a simple enclosed chute. Said chute may have any of the usual slug eliminators and the like, incorporated therein, but inasmuch as devices of that character form the subject of a co-pending application, such device is not shown herein. The chute enters the casing as at 65, leading from a coin slot 66 downwardly over the inner end of the shaft and terminates in a coin ejecting end 6'?. Said end is aligned with a coin holding slot 6'?a provided in the segment. When a coin drops out of the Achute it enters slot 67a, in the segment, and is brought to a stop by the foot on the other segment. Thusthe coin forms a physical medium between the two segments.

As the operating lever is moved. the sha'tt is moved to rock the stepped segment. rlthe coin causes the stepped. segment to impe the other segment to move the integral sleeve and the latch releasing; member. As soon as the stepped seoinent is allowed to return the toot moves out trom under the coin slot and the coin is released and falls thru said slot to a coin box, (not shown).

rlhe magazine is provided with a star wheel 70, having a plura ity ot l!" notches, correspondinl in number to the article holders. To the arm (S2, as at 7l, there is pivoted a vertically extended linlr Below the star wheel a centering pswl Z3 is provided which is pivoted to the trame as at 7i. Said pawl has a pointed end adapted to enter any V notch which is approximately aligned with it. rEhe pawl rests on can /Z'G which is pivoted to the iframe as at 7 The upper end ot' the link as at T8 .is pivoted to au e2;- tension 79 ot the cam. Thus upward morementof the arm 32 raises the extension end of the cam and rocks the pointed end ot the pawl upwardly so that it enters the V notch with which it is approzi'inuitely a i lJed. 'lhe parts just described are so arranged vhat th0 lirst upward movement ot the arm G2 will operate the cam to in turn operate the pawl. Thus, tirst movement et the arm G2, causes the star wheel to turn slightly and to become locked in such position until the arm. 62 is returned to almost. normal position. Aitor the pawlis moved into a v notcl the cam is free to turn because ot the coaxial perimeter 79 thereof, which only holds the pawl in place without tending` to move it further.

The star wheel and its notches are so arranged that when the pawl is in place a latch will be in operative ree'istration with the latch releasing' meinber. liiovement and locking ot the star wheel is or course timed to take place before the latch release comes in contact with a r ",stered holder.

From the foregoing description et the parts, and from toe iioiegroin'33` descriptions oii the actions oi'l some ot the parts, the operation o't the machine is quite apparent but the 'following will serve to more fully ef;- plain the operation ot the machine al whole. A prospective patron, taci-og; machine, can quickly learn the entire contents et the machine by looking at the eitposed ends ot the article holders, or by reteren-ce to the menu-card. It an artf lle holder is empty the patron can see it to be a tact. it further protection for the patron is that he can sce any article holder which is in registration with the arrow and discharge chute. rllhere is no excuse iter selecting' a*- empty article holder. The machine may include means ior returning a deposited coin, in case the patron operates the machine with an empty holder in position, but such means is set forth in my cio-pending application Serial Number 56,707, and needs no description herein.

Inspection and selection may be carried on by any prospective buyer without need ot depositing` a coin. TWhen an article is selected a coin may be dropped in the chute and allowed to gravitate to the coin controlled parts. .Depression ot the operating lever will then cause the latch releasing member to move upwardly as explained. lf the article holder has not been positioned correctly, the pawl will act on the star wheel to properly position the holder just before the latch release comes into Contact with the late1 The registered latch is downwardly directed as shown and as the latch releasing member mores up against its inclined suritace, the latch moves outward to release the bolt. '.fhe spring which connects the bolt with the yoke, shortens in etiective length and draws the upper end ot the latch downwardly. ris a result the lower end et the holt mores downwardly and moves the closures into open position. Any loose paclror articles contained in the holder would ordinarily escape. by gravity and tall thru the open closures into the chute. In the ot a boxed sandwich, or the like, the bof; should tit quite closely in the article holder; it is understood that a sandwich, or the lilre, should be .tirst wrapped in suitable pa `)er betore being inserted in the beit. rlhe paper acts to protect and cushion the sandwich, and the sandwich so wrapped should be a close tit in the box. To prevent jarring oi' the sandwich, tl e boi: in turn should be a close ht in the holder. Such practice is common, but is here mentioned to show that under some conditions a boxed sandwich mi @ht not, and in fact should not, he able to escape by gravity. rlhe spring' pressed movable wall. however7 will positively eject the boxed sandwich without injury.

So long as the latch release is in operative position, or in other than ino1'ierative position, the pawl l s the star wheel. and ijf the self-ctn iandie is turned the belt will slip v A.'.iout moilng the magazine. @briously, movemento the magazine with the latch release in operative position would either act to jam, vdisturb or break some parts, or in successive packages being Until coin controlled parts are allowed to return to normal position, the cannot he moved, and before the parts are returned, the contained coin is released.

'llhe modilied form of the invention has the discharge chute located uppermost of the casing. ln such embodiment the other parts aresuitably arranged to contorni to the location ot the discharge chute. Since the article holders are capable of ejecting their contents, an article holder which is aaa opened to the chute shown will move its art-icles up until it projects from the chute sufiiciently to be reached by the purchaser.

It will be apparent now that we have provided what might well be called a mechanical coin controlled store adapted to mechanically vend almost anything from a paper or pins to a piece of pie, the number of diiierent articles veing limited only by the number of article holders; and it will also be apparent that we have provided a fully selective machine in which a very satisfactory percentage of the volume of the machine may be occupied by goods to be vended, and

lWhile we have shown and described a specific embodiment of our invention, and a specific form of article holder, and .speciiic arrangement of article holders, and while we specify speciiic constructions and arrangements of parts, we have been specific only that we might describe one practical embodiment of our invention` and we do not limit ourselves to any specific construction or arrangement of parts, and we may alter the construction and arrangement or parts and employ other suitable ty ses of article holders without enlarging the scope of our invention and without departing from the spirit thereof, within the appended claims.
