' to release or Patented Dec. 10, 1929 OTTO W. TIMM. 0F EAGLE ROCK, CALIFORNIA AUTOMATIC SELECTIVE VENDlNG MACHINE Application filed January 19, 1927. Serial No. 162,036.

The present invention relates to selective vending machines of the type in which there is provided a magazine movable to dispose any pro-selected contained article into registration wita a coin controlled mechanism for causing the release or ejection of the preselected article.

In machines of such type it is usually required that the operator first move the magazine to bring the selected article into prooer position, after which the coin is deposited. The article can then be obtained only by the additional operation of manipulating another control device to supply the energy necessary eject theselected article.

My invention has for its principal object the provision of a machine in which any article may be pro-selected and delivered to the purchaser with less effort and fewer operations on the part of the purchaser.

Another object of the invention is to provide an automatic selective vending machine in which the desired article, when in the proper position, may be selected by the simple expedient of depositing the correct coin in a coin'slot. I

Another object of the invention is to provide for storing up energy for releasing and ejectin the selected article in such'manner that it is not necessar for the atron to de-' 3 press a lever or manipulate controls to ob tain the article; it being understood that inaccurate or hesitant manipulation of such controls often results in the loss of the deposited coin without the patron receiving any article in exchange.

Another object of the invention is to provide for positive and automatic release of a pro-selected article by automatic means beyond the control, and not dependent upon the strength or dexterity, of the operator.

Another important object of the invention is to provide a fully selective vending machine with a mechanism whereby the slight blow of a falling coin, or even the weight thereof, will act to release the contents of any article holder which has been brought into proper relation'with such mechanism.

Numerous other Ob ects and advantages of my invention will appear :herelnafter and will be better understood because of the order in which they appear.

I have illustrated by the accompanying drawings one practical embodiment of my invention; it being understood that the illustrations and the ensuing desc ription will sug- In the said drawings F igure 1 1s a front or, f

In carrying out my invention I employ a revoluble magazine having a plurality of radially arranged boxes or each opening radially outwardly.

holders, Each article holder is provided with a suitable door or closure with spring pressed means tending to open the closure and release or eJect the contents of the holder. is provided for each holde A latch or the like r and upon release of the latch the closure will be allowed to open, and the said spring pressed means will be free to release or ej of the holder.

ect the contents A selecting crank or handle is disposed exteriorly of a casing which encloses the article holders so that any preselected holder may be relation with the latch latch releasing means and store energy for its 0 moved into operative releasing means. The is arranged to receive peration and is held in inoperative position by a trigger; said trigger being arranged to be operated by a very slight force, so that a coin falling thereon will release the energy in the latch releasing means, causing it to release the latch so that the closure will open automatically.

More specifically, in carrying out my invention in the present embodiment, I employ a casing 10, having a discharge opening, and a discharge chute 11 leading to the said opening. The discharge chute 11 is provided interiorly of the casing with an open article receiving end 12. Any suitable design of chute may be employed for this purpose, and in my copending application, Serial No. 169,729 I haveshown and described a chute which is particularly suited for such purpose.

WVithin the casing there is provided a vertical frame 14, from which there extends a rigid horizontal shaft 15. Upon this shaft there is provided a revoluble sleeve 16 having an integral disc 17. The sleeve is also provided with a gear 18 which meshes with a gear 19; the latter being revoluble on an other shaft 20 carried by the frame. Integral with gear 19 is a bevel gear 21 meshing with another bevel gear 22. The latter is fixed to a shaft 23 which ranges downwardly of the casing and which is revolubly carried by the frame in bearings 24. Adjacent the lower end of the shaft 23 there is provided another bevel gear 25 meshing with still another gear 26. Gear 26 is fixed to a. horizontal lower shaft 27 which extends forwardly of the casing to terminate in a selective crank 28. By turning crank 28 the disc is revolved at a slower rate, such as five turns on the part of the crank belng requlred to effect one revolution of the disc.

Thedisc carries a plurality of radially arranged outwardly opening boxes or article holders 30. Each box is provided with a closure in the form of two doors or flaps 31, each hinged to the box, as at 32. Each door is provided with ears 33, contiguous with the front of the box, and by means of pins 34., each door is connected with a slotted yoke 35. The yoke 35 is provided with a vertically rising portion or bolt 36, which passes under a guide 37 so that the yoke is guided in vertical movement. Springs 38, coiled around the hinge pins 39, serve to hold the closure in closed position so that they are capable of supporting a contained article, such as 10, against all normally encountered forces. The belt is extended upwardly above thebox to terminate in a bent end 41, which projects horizontally forwardly of the box. Depression of the bolt will force the doors open in the position in which they are shown in Fig. 4, and will allow the contents to gravitate from the box freely, particularly since the doors may be moved outwardly to a vertical position beyond the plane of the sides of the box. A small cut-away spring portion 42, of the front wall of the box, is formed with a protruding button 43, which coacts with the margin of a hole 14: in the bolt, to hold the closures open once they are moved to open position.

In a copending application I have illustrated and described a coin return mechanism, which may be employed in conjunction with the machine now being described, for the purpose of causing the depressed end d1 of a bolt to actuate the coin return means so that if a coin is introduced to the machine when an open box is aligned with the dis charge chute, the coin will be returner without operating the machine. Hence this is the reason for causing a box, once opened, to remain open-until it is properly refilled.

The boxes are each attached to the disc, as at 47, 47, etc. It will be apparent now that by turning the selecting handle, the closure end of any article holder may be brought in direct alignment with the discharge chute; the latter being spaced downwardly sufficiently to permit of free opening of the doors. The assembly of boxes with the disc and sleeve is hereinafter known as the magazine.

Pivoted to the frame, as at 50, I provide a lever 51, having a projecting pin 52 disposed immediately above the belt of the immediately underlying holder. Downward movement of the pin, by reason of the lever pivoting on its pivot, will result in the pin 52 striking the bolt of the underlying article holder to release the contents thereof. The lever 51 and the pin 52 are hereinafter known as the ejector.

' Integral with the gear 21 there is provided a star wheel 53. Said star wheel is provided with depression 54: in which works a roller 55 carried by a spring controlled arm 56. The arm is pivoted to the frame, as at 57, and is held by a spring 57 so that the roller coacts with the star wheel to center the magazine. Thus, when ever the selecting handle is released, the tension of the'spring 57 will act to move the magazine slightly so that the article holder then nearest the chute will be properly aligned therewith and with the pin 52; the latter being practically in vertical alignment with the receiving end of the discharge chute.

A trigger 59 is pivoted to the frame, as at 60, and has an extension 61 reaching dewnwardly and rearwardly to terminate below the open end 62 of a coin chute 62. The coin chute leads from a coin slot 63 exteriorly of the casing. A coin having reached the open end of the chute will strike the trigger. Intermediately of the pivot point and the end ,of the trigger there is provided a notch 64-,

in which a pointed end 65 of lever 51 rests when allowed to do so. The lever 51 is provided with a strong spring 66, which acts to 'hold the lever 51 in. engagement with the trigger. Obviously-depression of the trigger being will result in. the: notched. port-ion moved downwardly sothat-the-lower end 65 of lever 51 is free to swing away while the spring actuated lever 51 and its attached pin, is descending toward the discharge chute. The rear end of the trigger, beyond the pivot thereof, is provided with an integral weight which at all times tends, to raise the forward end-of the trigger and to cause engagement of the end of lever 51 with the notch 64.

A pawl 67 is pivoted, as at 68, to the free end of the arm 56. Lever 51 is provided with a ratchet member 69, so disposed as to be engaged by pawl 67 when the lever 51 has been released by the trigger 59. Said ratchet member ispivoted to lever51, as at 70, and is provided at each end with stops 71 and 72, re spectively, which limit movement of said ratchet member. The upper stop '51 is so positioned that. when the parts are in the position shown in Fig. 5, downward movement of lever 51 will result in pawl 67 striking the ratchet member and moving its upper end outwardly from the lever, whereupon the lower stop 72 strikes the lever 51 and rocks its end 65 over into position where it may engage notch 64.

Lever 51 is provided with a rounded surface 74 on which pawl 67 rests. lVhen the lever is disposed in the position shown in Fig. 2, this surface holds the pawl in such position that it cannot engage the ratchet member.

'" When the lever 51 has swung downwardly into the position shown in Fig. 5, the surface 74 is so disposed as to allow the pawl to engage the ratchet member when arm 56 is moved downwardly by reason of the roller thereof riding over a raised part of the star wheel.

The operation of the machine as a whole will be understood from the following z- When the selecting handle is turned, the magazine is driven through the gears so that any desired article holder may be moved into registration with the discharge chute. An arrow 80 on the front glass covering 81 serves to indicate the position into which the desired article must be moved. lVhen themachine is loaded and first placed in use, the parts are in the position shown in Fig. 2, with the lever 51 held in position by reason of the trigger engagin it. As the magazine is revolved, the roller on arm 56 rides on the perimeter of the star wheel, but the motion imparted thereby, to the pawl, has no effect upon the lever 51, or on the ratchet member, because of the fact that the pawl cannot then engage the ratchet member, as previously explained. The star wheel is soadjusted that the arm 56 is in lowermost position when the roller thereof rides on the highest part of the star wheel, and when in such position, no article holder is directly aligned with the discharge chute.

A small projection 82, on the arm 56 coacts with means (not showfi) whereby a coin inserted in the coin slot will be returned. When an article holder-is in correct discharging relation to the discharge chute, the roller on arm 56 is in a depression of the star wheel and the machine is ready to receive a coin and discharge the contents of the selected article holder. A coin is inserted in the coin chute and sliding through the chute strikes the trigger and releases it. Thus the energy of the spring controlling the lever 51 is released, and the pin 52 is thereby moved forcibly downwardly, striking the protruding end of the bolt of the article holder and opening the closures to release the contained article. shown in Fig. 5, and remain so until another article is to be selected. By other means, also shown in the said copending application, the machine is inca )able of receiving and retaining a coin until the magazine is moved to bring a loaded holder intodischarging position. Therefore the machine cannot be operated until the magazine is again moved. The first movement which takes place on the part of the magazine results in the star wheel forcing the free end of the arm 56 downwardly. The pawl thereby is forced downwardly striking the ratchet member. The ratchet member, or rather its lower stop, abuts the lever 51 and causes its lower end to be rocked outwardly against the tension of the spring. Thus, first turning movement of the magazine cocks the machine by storing up energy in the spring. As the lower end 65, of the lever, rides over the margin 64, the weighted end of the trigger raises the trigger and causes the notch and the end 65 of the lever to engage. Thus the parts are locked in the position shown in Fig. 2, awaiting the insertion of another coin. By the means referred to, such coin cannot find its way to the trigger until a loaded article holder is in position to discharge into the chute] Of course, when the machine is cooked, the magazine can be turned indefinitely without effecting the position of the lever 51 and the trigger 59. When another coin does find its way to the trigger, the operation of releasing the contents by the energy stored in the spring, is again repeated.

It will be apparent now that the machine is quite automatic, and to purchase any of the contained articles, it is only necessary to move the magazine to properly position the desired article, and then inserting the coin, the energy stored by first movement of the magazine, serving to do all the rest, and the usual operating lever common to selective vending machines is dispensed with. At any time a person steps up to a machine and sees the desired article aligned with the indicating arrow, the only operation necessary upon his part is the insertion of the correct coin in the The parts are then in the position.

coin slot; gravity and stored energy accomplishes the rest.
