Application filed lully 3, 1323. Serial No. 649,226.
To all whom it may concern:
Be it known that 15, Jens ll. hflournnsnn, a citizen of the United States, and resident of Brooklyn, in the county of Kings and State of New York, have llIVGIltGQlCQltt-tlll new and useful Improvements in Coin-Gont-ro'lled' Vending Machines,- of which the following is a specification.
The invention relates to improvements in coin-controlled vending machines adapted to stand upon a counter or shelf and be utilized for the sale of chewing gum or other goods prepared in small packages and arranged in columns within the machine.
One purpose of the invention is to produce a comparatively small good-appearing machine having a transparent casing'throu gh which the merchandise may be observed and which although small in size is of large capacity so as to not require replenishing at too frequent intervals. of the invention is to provide a machine of the character referred to, formed of durable parts and capable of ready operation on the introduction into the machine of a predotermined coin througi an exposed slot formed in the base frame of the machine. Another purpose of the invention is to provide a machine which will, with certainty, when operated, deliver the sold pieces of goods to the purchaser.
In carrying out my invention l provide a hOllOW metallic base within which the major portion of the operative mechanism is contained, and upon th'isbasel mount a vertical rotary irame having a circular series of vertical trays for the pieces of chewing gum or other merchandise sold, and this rotary frame is enclosed by a cylindrical glass casing which is secured to the base frame by a central rod extending through the glass casing, said rotary frame and said base frame. The special features of the invention and the construction and operation of the several mechanical parts comprising the same, will be understood from the detailed description hereinafter presented, refcrence being had to the accompanying drawings, in which: Y

In the drawings, 15 designates hollow cylindrica base frame or stand and 16 a hollow cylindrical transparent casing mounted upon said base frame and firmly'sccured in position thereupon by means of a central rod 17 having a polygonal head-'18 (Fig. 2) located in a polygonal aperture in Zone, n. Y., a con-ronnrron or having been operated by the r in Figs. 2
the bottom plate 19 of said base 15, said head 18 serving to prevent the rotation of the rod 17. The lower end of the rod l? has a head 20 engaging the bottom lilthe base casing and aiding in securing said bottom firmly, though detachably, in position. The base frame 15 has cylindrical vertical walls and is formed with a top 21 on which the transparent casing it; rests and with a surrounding flange 14 to position said casing on said top and said top 21 is formed with a central opening 22, w'iose purpose will be hereinafter ex lained, ant. also with a slot 23 for the pieces of chewing gum or the like 24 (Fig. l), as the respective columns of the merchandise are successfully brought over said opening 23. The base 15 is formed at one side with a coin entrance slot 25, which is vertical, and with an elongated horizontal slot out through which the operating handle or rod 2? extends in convenient position to be moved from one end of the slot (Fig. to the other end thereof (Fig. '7) and back to its first position shown in Figs. 1 and The operating handle 27 will be manually moved or swung from its position shown in 1 to that illustrated in Fig. and thereupon upon the release of said handle 2. the handle is returned to its initial position by means of the spring 28 which is placed under tension on the movement of said handle to the position shown in Fig. 7. The base frame 15 is also formed with an exit opening 29 to which the sold pieces of chewing gum automatically desceind, a chute being provided within the chamber of the base 15 to receive the sold pieces of n'ierchandise and direct them downwardly to the discharge opening 29. The chute 30 will ordinarily be formed of tin and is of borc f ormation. as shown in Figs. 2 8, 9 and 10 said box-for: ation being represented in rear perspective and 10 in bottom elevation in Fig. 8 and in section in Fig. 9. The sides of the chute 30 are flanged outwardly at their outer edges, as at 81, and secured to the base frame by means of screws 32. The chu" 30 is stationary and rigid with the base e 15 *ner pen the top lvithin the The glass casing 16 is in the L of an inverted jar and rests plate 21 of the base casting 15. transparent casing 16 is confined rotary frame for holding the pieces of chewin gum or the like 24:, and this rotary t; .n 33 is formed of tin sections whose outline is more clearly represented in Fig. 3. The tin sections are arranged in circular disposition and secured at their upper ends to a ring or collar 34 by means of screws 35, and a their lower ends to a ring or collar 36 by means of screws 37. The tin sections constituting the rotary frame 33 form compartments :38 for the stacks of chewing gum 2st, and in the present instance there are eight of the vertical compartments 38 adapted to contain eight vertical columns or stacks of the chewing gum. Each section of the rotary frame 33 comprises four integral members which, in Fig. 3, 1 number 39, 40, 4-1 and respectively. i i hen the frame is made up of the sections each comprising the parts 09. l0, 4:1 and 42, the compartments 38 may stand substantially radial of the rotary frame and each of the sections may be stamped up out of sheet metal. The outer edge of the member 39 of each of the sections closely engages the adjacent outer edge of the member 42 of the next adjacent section, and the outer edge of the member 42 of each section closely engages the outer edge of the member 3 of a preceding section as illustrated at the right hand side of Fig. 3. The several sections comprisin the rotary frame 33 may be readily and cheaply made and assembled, and in addition they may be secured at their inner ends or members ll to the uppe and lower rings or collars 36.
Upon the stacks of chewing gum Ql is loosely applied a weight 43 which is in the form of a ring and has inwardly extending arms id to enter the compartments and rest upon the upper ends of the stacks of chewing gum 24.
It is desirable that the weight may slide downwardly with the diminishing stacks of chewing gum 24:, as the chewing gum is sold, and also desirable that the weight 4.3 shall not tilt upwardly from the chewing gum in the event that the machine should be turned upon itself, and therefore in the members ll. of substantially op compartments 38 1 form a vertical series of ratchetteeth and provi lo the weight 43 with looking pins :6 which are springpressed aganst the teeth il-5 and are beveled downwardly and outv-Jardly at their inner ends to slide downwardly over the teeth 45, but become locked against upward movement by engagement with said teeth. The teeth 45 are pressed out of the tin of the tray sections and the pins 46 are met ted in horizontal openings in the weight 4 and have upwardly extending exposed outer ends or finger-holds 47 by means of which the locking pins may be pressed outwardly from the ratchet teeth and permit the weight 43 to he slid upwardly on the tray sect-ions or be removed entirely therefrom. The ratchet teeth 45 incline downwardly and outwardly and the inner ends of the locking pins 46 have a like inclinathm, as shown in Fig. 2.
The lower collar 36 is formed with a l hub section 48 which fits within the ho formed in the t pplate 21 of the based 15, as shown in Figs. 2 and 1- and this hub 48 serves as means for centering the rotary frame 33 within the machine. The hub 48 is less in diameter than the upper porlll) tions of the collar 36, and hence an annular shoul'd'er 469 is formed to seat upon the top 21 of the base frame 15 along the edges of the opening 22 therein. and means of said shoulder 4-9 the weight of the rotary frame 33 is support-ed upon the said top plate 21.
The top of the transparent casing 16 formed with an opening and within this opening is suspended a sleeve 51 which is integral with a. disk 52 supported upon the top of the casing 16, a packing 53 being placed below the disk 52 to cushion the pressure of said disk on the glass casing. The sleeve 51 is open at its upper end and said sleeve receives the upper threaded end 54 of the rod 17, as shown in Fig. 12 said upper end of the rod 17 also having a plain stem 55 extending upwardly from its threaded portion 54. The rod 17 is secured at its upper end by means of a threaded sleeve which is screwed downwardly upon the threaded portion of said rod 1'2", said sleeve 56 then entering the sleeve 51 and finally becoming concealed therein as shown in Fig. 2. The threaded sleeve 56 may be applied upon the upper threaded portion of the rod 17 by any convenient means. but I preferably use for that purpose a key 5'? having a hollow threaded lower end 53 adapted to enter the bore of the sleeve 56. The thread on the key 57 is l'eft ha-nded and the bore of the sleeve has revers'ely threaded sections, one to be engaged by the thread on the key and the other to engage the threaded end 5% on the rod 17 and hence when the thread 58 is screwed into the sleeve 56 and by the force of the key the sleeve 56 is screwed down against the bottom of the sleeve 51 which becomes an arresting point, the continued motion of the key 57 operates to unscrew the key from the sleeve 56, leavin said sleeve within and a ainst the bottom of the sleeve 51, thereby locking the upper end of the rod 17 invp-ositio'n and securing the transparent casing 16 upon the base frame 15, the lower end of said rod having been secured against rotation within the bottom 19 of the base casing 15 by means of the polygonal head 18 and having been given a firm bearing against said bottom 19 by means of the head 2-0. The bottom 19 seats against an annular shoulder 60 formed within the lower end of the base frame 15.
Upon the rod 17 at some intermediate point I- provide an adjustable stop-collar 59 which is made use of as means for preventing the complete detachment of the rotary frame 33 from the machine at such times as the sleeve 56 may be detached from the upper end of the rod 17 and the casing 16 lifted off from the base 15. When the trans parent casing 16 is removed from the machine, the rotary frame 33 may be slid upwardly on the rod 17 fo any purpose that may require such action and at such time the base of the collar 36 will strike against the stop collar 59 and arrest the frame 33 against further upward movement.
The key 5? also made use offer removing the sleeve 56 from the upper end of the rod 17, this being accomplished by screwing'th'e lower end of the key into the upper end ofthe sleeve 56 and then rotating the key for causing the sleeve 56 to ride upwardly on and from the threaded portion 54 of the rod 17.
I have described all of the features of the machine located above the top plate 21 of the base frame 15 and I will now describe the mechanical features con "ned within the chamber of said'base frame.
Below the top plate 21 of the base 15 and close against the under surface of said top plate and against the lower surface of the hub 48, is mounted to rotate on the rod 1'? with'the rotary goods-holding frame 33, a plate 61 of the outline more clearly illustrated in Figs. 5,, 6 and 7, this plate 61 being of general disk outline and fastened to the hub 48 by means of screws 62. The outline of the plate 61 also conforms substantially to the outline in cross-section of the rotary frame 33, and the plate 61 is recessed inwardly, as at to conform to the vertical compartments 38 in the frame 33 and also to conform toas they pass in succession under, the opening 23 in the top-plate 21. The recesses 63 in the plate 61 are in the outline of the pieces of chewing gum 24, and dur ing the rotation of the goods-holding frame 33 and plate 61, the recesses 63 are successively carried below the opening 23 in the top plate 21 and receive a piece of gum therefrom. The plate 61 is of the thickness of one piece of gum 2 and the top plate 2-1 at the opening 23 therein is of the thickness of one piece of gum, and hence in the nor mal position of the parts of the machine, the two lower pieces ofgum of a stack or column thereof will be below the upper surface of the top plate 21, one of said pieces being in an opening 63 of the plate 61 and the other piece being in the opening 23- of the top plate 21, as shown in Figs. 2 and 10. The pieces of gum confined in the opening 23 of the top plate 21 and the recess 63 below said opening, in the plate 61, are'supported upon a segmental plate 64 whose outline in bottom elevation is shown in Fig. 8 and whose outline in top view is more clearly illustrated in Figs. 6 and 7. The plate 64: defines something less than a half-circle and is mounted to oscillate upon the vertical rod 17 independently of the plate 61, which rotates with the frame 33. The plate 64 has a depending hub 65 (Fig. 2) and is supported thereat on a coil'ed spring 66 which is interposed upon the rod 17 between the bottom of the base l and a washer 67 engaging and aitording a bearing for the lower end of the hub 65. The plate 64- is thus spring-pressed a ainst the lower surface of the plate 61 and as a close frictional engagement therewith. The plate 64 has along its outer edge a depending flange 98 which normally closes the slot 26 in the base 15, and to the plate 64 is fastened the handle 27 which projects out through the slot 26 and by means of which said plate 64; may be moved from its initial position shown in Fig. 5 to its extreme other position shown in Fig. '7. The plate 64; is formed with an elongated opening 68 which conforms to the opening 23 in the top plate 21 and the individual recesses 63 of the plate or. The opening 68 in the plate 64 is non mally not in vertical alignment with the aforesaid openings 23, 63, and hence said plate '4 may support the stack of confections at said openings 2 63 in the manner shown in Figs. 2 and 16. The plate 64 is iiormed with a vertical receiver 69 for a coin 70 introduced through the coin entrance slot formed in the base 15, said receiver 69 being normally in line with said slot 25 so that a coin may be pushed through the slot and directly into said receiver, which is open at its outer end and at its upper and lower ends and closed at its inner ends. A coin TO pushed into the receiver 69 will rest upon a segmental tramway plate 71 which is of sheet metal and secured by screws to the side wall of the base 15, as shown in Figs. 8 and 11, and the coin will remain supported on the tramway 71 until, by means of the lever or handle 27, the plate 6 1 is moved from its initial position, shown in Fig. 1, along the slot 26 until the coin is :arried beyond the far end of the tramway plate 71.
l utilize the coin 70 as means for rotating the plate 61 and rotary frame 33, said coin when introduced into the coin receiver 69 and standing on edge on the tramway plate 71, projecting upwardly within the recess 63 of the plate 61 above the coin, as shown in Figs. 5 and 11. When the coin is in the position indicated in Fig. 11 with its upper edge within one of the recesses 63 of the plate 61, and the handle 27 is started in motion from its position shown in Fig. 5, the coin will on a limited movement of the plate 6% be carried against the side edge of the recess into which it projected, as shown in Fig. 6, and thereupon upon the continued movement of the handle 2'? said coin will act as a dog pressing against the edge of said recess to rotate the plate 61 and frame 33 until the handle 27 has reached the limit of its movement toward the left, as shown in Fig. 7, the coin thus rotating the plate 61 and frame 33 to the extent of the movement of the handle 27 from the position shown in Fig. 6 to that shown in Fig. T. ll hen the handle 27 has reached its position shown in Fig. 7, the proper movement will have been given to the plate 61 and rotary :tramc 33 and said plate and frame will thereupon come to rest, and the hand of the operator will be released from the handle 27, during the movement of the plate 6% and handle 27 from their initial position shown in F 5 to that position shown in Fig. 7, the spring 28 hereinbefore referred to is placed under increased tension, and when the hand of the operator is released from the handle 27, said spring will retract said plate from its position shown in Fig. 7 to that shown in Figs. 5 and 6, thus restoring the plate (i l to its initial position without disturl".g the then position ot the plate 61 and frznne ll hen the handle 27 is released, the pressure of the coin 76 against the edge of the recess becomes released and the coin falls downwardly into the chamber of the base 15 During the movement of the plate 64 from its position shown in 5 to that shown in Fig. 7, the frame 33 during its period of rotation moves the stack of chewing gum from above the aligned opening 23 in the top plate 21 and the recess 63 below it of the plate 61, along the upper surface of the top plate 21, leaving the two bottom pieces of the stack in the opening 23 and recess 63 where they are seen in Figs. 2 and 10, and during this same movement of the plate 64, the frame 33 carries the succeeding stack of chewing gum to position above the opening 23 in the top plate.
In the normal position of the oscillatory plate 64-, the opening 68 therein is directly over the chute 30, this being the condition represented in Fig. 5 in which the chute 30 is indicated by the dotted lines below said opening 68. It is to be noted that the opening 68 is at this time beyond the column of chewing gum whose two lower pieces are in the openings 23, 63, respectively,'as shown in Figs. 2 and 10. When the handle 27 is turned toward the left from the position shown in Fig. 5, the plate 6 1 carries the opening 68 beyond the chute 30 and around to the position in which said opening is shown in Fig. 7, and during this same movement of the arm 27, the rotation of the plate 61 carries the lower piece of confection held within its recess 63, shown in Fig. 10, toward the left and to the position shown in Fig. 7, said piece of confection then being directly over the chute 30 and supported upon the plate 64. The movement of the plate 61 which carries the lower piece of gum to the position over the chute 30, also carried the succeeding recess 63 of the plate 'to the position previously occupied by said lower piece of gum and also, by the rotation of the frame 33, carried the succeeding stack of pieces 24 to a coin is inserted the position occupied by that shown in 10. On this operation when the bottom piece of gum was carried to the left from the position shown in Fig. 10 to the position above the chute 30 shown in g the piece of gum immediately over said bottom piece, or the piece held in the opening 23, became supported upon the moving plate 61 until the succeedir recess 68 of said plate reached said pi. of gum, and at that time said piece of gum became uns nported and fell from the opening 23 into the recess 68 of the plate 61 then positioned to receive said piece, and the succeeding stack of gum ha. g at the same time reached a position oi er the opening 23-, he
bottom piece of the stack fell into said opening 23 and upon the piece of gum which just previously fell from said opening into the recess 6?) of he plate 61, thus restor ing the condition shown in Fig. 10 at the end of each movement of-thc handle 27 from its position shown in Fig. 5 to that shown in Fig. 7, the one piece of goods carried around by the plate 61 to :a position above the chute 30 still remaining upon the oscillatory plate 64. Upon the release of the hand of the operator from the handle 127, the spring 28 will restore said handle and the plate 6% to their initial position, and when the plate 6% reaches its initial condition, the opening 68therein is directly over the chute '35) and below the sold piece of gum, which then falls through the opening 68 and into the chute. 30 a-nd'passes to the. discharge opening 29,. The sold piece of gum is not delivered dnringthe active movement of the handle 27 from its position shown in Fig. .5 toythat shown in Fig. 7, but on the return movement-of said handle and of the plate 64 to their initial position under the influence of the spring 28.
Within the base 15is pivotally secured an arm carrying a dog 81 which is normally held within one of the recesses 63 of the plate 61 by means of a leaf-spring 82, as shown in Fig. 7. When the dog 81 is in position in the recess 63 it will prevent the rotation of the plate 61, and at that time the oscillatory plate 64 may be moved freely, not having positive connection with the plate 6.1. When through the coinslot 25 and the plate or is moved by the arm 27, a cam bar 83 rigid with said plate 64 will move against the dog 81 to turn the same outwardly from the recess 63 of the plate 61 and then as the rotary plate til-starts in motion under the force of thecoin acting against it, the cam bar will pass from the dog 81 and said dog will become flexed against the periphery of the plate 61 advancing toward it in rear of the recess the doghad just occupied and which has advanced in a direction from the dog (Fig. 6). Upon the plate 61 completing its predetermined movement the dog 81 will enter the succeeding recess 63 then brought opposite to the dog (Fig. 'i) and again lock the plate 61 against movement with the plate 64 e r ept after plate 6 L has returned to fial position and another coin has been its 1 inserted into the machine. \Vhen the plate 6 t is moved without a coin having been introduced. into the machine, the cam-bar 83 will move against the dog 81' but on such movements the dog will simply pass from and return into the same recess 63, since at that time there is no movement of the plate 61 to carry the recess from the dog or to present a portion of its pci'phery to the dog. The dog 81 has a depe, ng member 84, as shown in Fig. 18, and this member is in the path of the cam-bar 83 and is acted upon thereby to displace the dog outwardly from the recesses of the plate 61. lhe dog 81 limits the advance movements of the rotary frame 33 and prevents said frame from having reverse movements with the oscillatory plate 6d.
A plate or shelf 99 may be secured to the far upper edge of. the chute 30 and extend in advance thereof to a suliicient extent to serve as a support for or to aid in supporting the plate 64 when the same is turned its full strolreby means of the handle 27, as shown in Fi 7.
Among the advantages of my invention I may call attention to the simplicity anddurable nature of the mechanical parts of the machine, to the fact that during the operation of the machine the one handle'Q/Z, with a coin in position, operates the plate 6% and rotates, by step-by-step movements always in the same direction, the rotary goods-holding frame .33 c and plate 61, said frame 33 and plate 61 moving as one integral part, and to the fact that the sold pieces of gum are not finally discharged under the pressure of any part acting against them but at a time when theplate 6& has returned to its normal posi tion and the mechanism'of the machine is at rest, the sold piece inerelyfalling by gravity Whentlre support (plate 6%) slides from below said piece, which is then stationary, and leaves'its opening 68 between said piece and the open topof the chute 30. The machine from which the drawings were made has a capacity for holding four hundred pieces of one cent gum. Other advantages of the invention will be apparent from the detailed description alread-ygiven and it is believed further explanation is unnecessary.
