T ([ZZ wii-0m if may co ncern Be it known that l'. Janas H. MGELLAN. citizen of the Dominion of Canada. residing at Vancouver. in the Province of British Columbia. Canada, have invented certain new and useful l'mprovements in Soft-Drink- Vending Machines, of which the following is a specification.
This invention relates to a machine for vending liquids, such as softdrinks. the liquid being measured to and served in a paper cup or tumbler.
'The invention comprises a measnring cylinder with a piston movable in it. which cylinder receives a 'charge of the liquid the machine is designed to dispense from a reservoir within the machine and normallv maintains itready for delivery into a paper cup for presentation to the vendee.
The paper c-ups are nestcd within a magazine from which onel is withdrawn coincident with the charging of the measuring cylinder.
The several Operations involved in this delivery are performed by a handled lever` outside the casing of the machine. which handled lever is opcratively connected to the mechanism within the casing by the deposit of a coin of the required size in a slot provided.
The downward movement of the external handled lever from its normal upward position effects the expression of the contents from the measuring cylinder into the cup which has previously been withdrawn from the magazine and placed beneath the cylinder. lt also moves the filled cup from beneath the measuring cylinder into position beneath the aperture through which the cup is delivered for presentation to the vendee. The same downward movement places a spring or series of Springs within the machine under tension, which tension restores the external Operating handle tots upward position. delivers the charged cup to the vendee` recharges the measuring cylinder and releases a cup from the magazine and places it in position beneath the measuring cylinder ready for filling for the next purchaser;
The means by which these several operations are performed is fully set forth in the following specification, reference being made to the drawings by which it is accompanied. in which:
lfig. lis a Vertical section through the casing on the line 1-1 in 2,. showing the internal mechanism in elevation` the operating handled lever being shown in dot and dash lines.
Fig. 2 is a plan of the same with the upper part of the casing removed.
Fig. 3 is a detail of the means by which the external Operating handle is connected to the Operating shaft within the machine by the presentation of a coin, the mechanism being shown in the normal position.
Fig. 4 is a similar view showing the mechanism in the position where the coin is released after the required movement of the internal mechanism is effected.
Fig. 5 is an elevation of Fig. 3 taken in the direction of the arrow 5.
Fig. 6 is an enlarged detail showing the cup release from the magazine in section.
Figs. 7 and 8 show the cup release plates of one side at the two extremes of their movement. i
Fig. .9 is a cross section on the line 9-9 in Fig. 8. showing the means by which the bottom cup of the nest in the magazine is withdrawn.
Fig. 10 is an end elevation showing the meansiby which the cup release plates are operated.
Fig. 11 is a detail sectional elevation of the mechanism by which the cup is moved forward from its position beneath the magazine cylinder to the position for presentation to the vendee. and
Fig. 12 is a plan of the same.
The frame to which the several parts of the mechanism are connected is represflnted by 2. and 3 represents the casing by which the same is enclosed. which casing is providcd with loeked means of access which are not described. as it forms no part of the invention.
In this frame 2 is rockably mounted a shaft 4 to which the several parts of ,the operative mechanism are connected or 'ecured One end of this shaft 4 (see Figs. 3. 4 and 5) projects through the side of the casing 3 and on the outwardly projecting end is rockably mounted the external handled lever 5 by which the mechanism is operated. the hub 6 of which lever passes through the casing 3. This handled lever 5 is retained on the end of the shaft 4 in any manner that will permit the handle to rock freely on the shaft without the shaft beinw accessible from outside the casing. Within this casing the hub 6 of the external lever 5 has a member 7 secured on it having a tongue 8 projecting from it, which tongue is normally held by a spring 12 against the stop 10 secured to the frame of the machine to project below the` lower end of a coin chute 11.
Within thecasinga lever 13 is secured on the shaft4 adjacent the inwardly projecting end of the hub 6 of the external handled lever 5. On this lever 13 is secured an ex,- tension 14 of the chute 11, which is normally held against the' stop 10 and in ali ment with the lower end of the chute lli y the main Operating spring 15 of the machine, (see Fig. 1), connected between the shorter end 16 of the .lever 13 and the base of the frame 2. The lower end of the chute extension 14 is slotted. (see Figs. 3 and 5) to 'permit passage of the tongue 8.
Thus, while no coin is in the machine, the external handle 5 may be freely moved without operating the shaft 4, but when a coin of suitable Size is passed into the chute 11, it will fall into the chute extension l14 and against the projection 9 on the member 7, and the coin will obstruct passage of the tongue 8 through the slot in the coin chute extension.14; and will thus form a driving connection between the external lever 5 and the shaft 4 in the direction of movement to operate the mechanism indicated by the arrow in Fg. 3. As the handled lever 5 moves upward under the tension of the spring 12, the internal Operating lever 13 with its ('oin chute extension 14 is retained'at the lower limit of its movement in a manner to be described, and the tongue 8, which moves with the lever 5 being withdrawn from contact with the coin in the chute extension 14,` the coin is free to fall into a removable receptacle 17 rovided, as soon as .the stop 9 clears the endp of the chute, as shown in Fig. 4.
A liquid measuring cylinder 18 is vertically supported in the frame 2, the lower end of which cylinder is formed with a delivery spout 19 closable with a valve 20 opening outward and held against its seat by a spring 21, the strength of which is sufficient to retain the contents in the cylinder until pressure is applied suflicient to overcome the sprin In this cylin er 18 is movable a piston 22 to which a rod 23 is, connected, which passes through the upper end cover 24 of the cylinder. Into the lower end of the cylinder 18 liquid is delivered from a reservoir 26, either by gravity or suction, through a pipe 25, a check valve 27 being in the connection of the pipe to the cylinder.
The piston rod- 23 is moved downward to exlpress the contents from the cylinder by a ever 28 pivoted at 29 to the frame 2, one end of which lever is connected by a link rod or rods 30 to the upper end of the piston rod 23, and the other end of the lever 28 is connected by a rod 31 to the shorter arm 16 of aus-1,982
the inside Operating lever 13 of the machine which is secured on the shaft 4.
The paper cups 33, which are formed with the usual flanged upper edge, are nested within a magazine 34 in which they may freely fall. The upper edge rim of the lower cup of those in the magazine rests onthe inner edges of two thin, flat plates 35 located one on each side of the cup. These plates rest on separating plates 37 which again rest on two plates 36 similar to 35. These plates 35 and 36 are retained together and arev endwise and laterally moved on pins 38 secured in the frame of the machine, which pins pass through angled slots 39 adjacent each end of each plate. The slots of the lower plates are oppositely angled to those of the upper plates, (see Figs. 7 and 8), so that as the plates are endwise moved forward o n the pins 38, the upper plates are constrained to recede from one another and the lower plates to approach one another, the movement being suflicient to withdraw the upperplates from the support atforded the upper flanged edge of the cup.
The plates 35, 36 on both sides of the cup are simultaneously moved forward by the forked end 40 of a lever 41 pivoted at 42 in brackets 43 secured to the frame of the machine, the operative connection vof which lever will be described later, and are normally held at the backward limit of their movement, with the u per plate 35 supporting the lower cup of t e magazine, as shown .in Fig. 6, by- Springs 44 between the ends 40 of the lever 41 which rojects through the plates, and pins secured in the frame '2' (see Fig. 1).
As the plates 35. 36 are moved from this normal position, the upper plates 35 are i withdrawn from support of the cu and allow the cups in the magazine to fal and the lower plates 36, having been simultaneously moved in, afford the' substitute support to the cups. As the plates 35, 36 return under the tension of the springs 44, the lower plates 36 are withdrawn releasing the lower cup, and the upper plates 35 are moved inward to su port those in the magazine.
To with raw the lower cup from the nest l in the magazine when the same is relieved from support, a small wire lever 45, 46. is pivotally mounted at 47 on the outer edge of each upper plate 35, opposite the position of that plates engagement with the cup. The inner end 45 of each lever is downwardly turned and passes through a transversely elongated aperture in each plate 35 adjacent the inner edge thereof to en the upper side of the flanged edge of the cup as it rests on the lower plate. Normally the inner end 45 of these levers is held slightly below the upper surface of the lower plate 36 by engagement with the dbwnwardly turned end 46 of the lever against the outer 2 Marma spring 48 secured to the back edge of the upper pla-te as the lower plate moves out- Ward.
The cup. 33, when released from the magazine, falls on two inclined guide wires 49 secured to the underside of that portion of the, frame which supports the magazine, which wires are parallel to one another at a distance apart slightly less than the smaller end of the cup. Down these guide wires 49 the cup falls and is diverted forward to a 'position immediately under the delivery spout 19 of the vmeasuring cylinder 18, at which position the cup is received and its fianged upper edge rests on two wires 50 bent to conform to the curvature of the cup flange. rll`hese wires 50 are pivotally mounted on a common pin' 51 and the after end of each Wire 50, beyond the pivot 51, is outwardly turned to the same side as its bend 50, and is upwardly turned as at 52 to enter a transverse slot 53 formed on the end of' a rod 54 slidably mounted to move endwise in bearings56 on a. member 57 which is itself endwise movable in guideways v58 parallel to the rod 54. w
The end of the rod 5d is downwardly turned to pass through an open ended slot 59 in the backward end of the slidable member 57 and below that member is angled toward theoriginal alignment of the rod 54, as at 55, for a purpose to be explained later.
The member 57 is endwise movable in slideways 58 to transfer the cup carried in 'the supports 50 from its position under the measuring cylinder 18 to a position, shown in dot and das'h lines in Figs. 1, 11 and 12, from which it can be lifted upward for presentation to' the vendee.
Endwise movement of the member 57 is etfected by the following means: lmmediatcly under the shorter end 16 of-the lever 13 is a bell crank lever 60, 61 which is pivotally v 'mouute-d at 62 in a member secured'to and projecting upward from the base 'of the frame 2. The shorter arm 61 of this lever is connected by a spring 63 to the end 16 of the lever 13 and the upper end of the arm of the bell crank lever is connected by a link 64 to a rod 65 which is secured across the backward end of the slidable member 57, so that as the-Operating lever 13 is moved down to the position indicated by the dot and dash lines in Fig. 1, by downward movement of the external'handle 5 in the manner previously described, tension is imposed on the spring 63, which tension tends to turn the bell crank lever on its pivot 62 and project the slidable member 57 with the cup 33 supported on'the members 50 forward to the position represented by the dot and dash lines.
To check this forward movement of the filled cup that it may move at a moderate Velocity, a rod 66 is secured to the after end of the member 57 and projects parallel therewith and its forward end passes into a tube 67 secured to the slideway 58. vAs the for- Ward end of this tube 67 is closed., the air within it forms an elastic check to movement of the member 57, the air leaking gradually past the fit of the rod 66 in the tube as thetension of the spring 63 exerts itself.
To ensure that the member 57 does not more forward until the liquid in the cylinrler 18 has been discharged into the cup 33, and .the cup lifting mecha-nism, to be described later, is clear of the cupls forward movement, the lever 61 is latched at lthe 'lower limit of its movement by a hook formed on the shorter arm of a bell crank lever 68 pivoted at 69 and released in a manuer to be described later.
rll`he filled cup is presented to the vendee through an aperture 71 in a horizontally disposed ledge or counter of the frame 2. This -aperture 71 is normally closed by a plate 72 in the manner descr1bed, moves down the lever 13 and with it the plate 72 to adjacent the bottom of the casing, leaving a clear space above the cup 75 immediately opposite the position of. a filled cup 33. To
retain this lever 13 in the downward position while the filled cup is being moved forward into the upward path of the plate 72, the shorter opposite end 16 of this lever is latched by ahook latch 7 6 pivoted at 7 7 to a member attached to the frame 2, the upper end of which hoolr member projects upward as at 78 to be engaged and the latch released by any suitable projection from the cup holding1 slide member 57. lin the drawing it is shown as engaged by the forwardly turned end 79 of the rod 65, by which connection is made to move that member. Thus, when the slidable member 57 is moved forward to transfer the filled cup from its normal position under the illing spout to a position. ready for presentation, as indicated by the dot and dash lines, the end 78 of the hooh latch 76 is engaged and that latch released, setting free ythe lever 13 to elevate the plate 72 under the tension of the spring 15, and checked by the synchronous movement of the piston 22 in the cylinder 18 while reeharging' the cylinder.
As the filled cup 33 stands in the path of the upward movement of the plate ,72, the filled cup is lifted in its receptacle 75 and is projected through the aperture 71 for the vendee.
The means vwas described by which the member 57 with the filled cup in the su ports 50. was projected forward into t e position indicated by dot and dash lines. That means was actuated by the tension of a stressed springwith provision to avoid precipitate movement. Forthat reason a separate means must be provided for returning the same after the supporting members 50 have been openedv to free them from the cup.
This means comprises a lever 80 be'nt` from wire to have a cam Outline somewhat as shown in Figs. 1 and 11. One end of this lever 80 is secured to the shaft 4 to move with it and the other end 81 is turned across under the plane of movement of the slidable member 57 which carries the cup supports 50. During the downward movement of the handled'lever 5 this lever 80 is moved upward to the position indicated by the dot and dash lines in Fig'. 11, with the end 81 adjacent the underside of 57 and the rear- Ward end of the slidewav 58 of that member. Later, when the slidable member 57 is moved forward under the influence of the spring` 63,' the tension on which was imposed'bv the samedownward movement, the
forwardly turned end of the rod 54 is moved up to the position indicated. When the shorter arm 16 of the lever 13 is released and under the influence of the spring 15, the lever 80 secured to the same shaft moves down with it. During the first part of the movement, the end 81 engages the forwardly directed end 55 of the rod 54 and moves that rod to the position indicated by the double dot and dash lines, in which movement the ends 52 of the cup supporting' members 50 are drawn together to open the' members 50 from engagement with the cup, as shown in Fig. 12. Thereafter the cam formed. outline of the lever`80 engages the rod secured in the slidable member 57 and moves that member back to itsnormal position with the centre of the members 50 under the cylinder 18, and at the latter end of this movement the upwardlyturned ends 52 of the cup holding members engage a transverse block 82 by which they are moved apart in' the slot 53 and close the 'members 50 to receive the next cup released from the magazine.
The release of a cup from the magazine,
as reviously described, must be coincident wit the completion of the backward movement of the slidable' member 57 in order that the cup supports 50 carried by that member may be in position when the Acup is released. i
The, lever 41, by which the cup, release from the magazine is operated, extends angularly backward and downward to a position adjacent the after end of the slidable member 57 at the backward limit of its movement, and freely pivoted in the end of this lever 41 is a short equal armed lever 53, the upper end of which is stopped against a projection adjacent the pivot and the other end 'of which is weighted that it may normally maintain an upright position against this stop with its -lower end projectingin the path of one of the bear- ,mg members 56 of the rod 54.
While th"e member 57 is moved forward to the position of presentation, 56 may pass freely under the member 83, as shown by the dot and dash lines in Fig. 1, but during .the return movement of the member 57 the member 56 engages the lower end of 83 and operates the lever 41 to effect release of a cup from the magazine in the manner described. The lever 41 is then restored to its normal position by the Springs 44. i
In describing' the means for forwardly moving the slidable member 57 a means was described for retaining the operative mechanism by which the movement was efected, while the cup 33 was filled from thel cylinder 18 and the presenting plate 72 was moved downward clear ofthe path of the cup carried by the member`57.
The bell crank 60, 61 by which the slidable member 57 is moved forward was shown as llatched by a small bell Crank 68 having a hook end to engage the shorter arm 61 of the Operating bell crank. The longer arm of the bell crank 68 has a rod 70 pin-connected to it, the upper end of which passes through an aperture in the produced end of the lever 28 by which the cylinder piston is operated, and the upper end of the rod is bent over or has a button end on it to be engaged by the end of the lever 28 adjacent the upper limit of that leverls movement,' and draws up the bell crank lever 68 to efl'ect release of the bell crank 60. 61 under the influence of its spring 63. This release being` operative by the mechanism which actuates 'the expression of the liquid from the cylinder, ensures that the expression terminates before the cup 33 is moved from under the spout to the position for presentation.
To ensure that a hasty or over-forcible pull on the handle lever 5 Will not subject the charging mechanism of the measuring cylinder to undue strain, the -connecting rod 31 between the shorter end 16 of the internal Operating lever 13 is not positively connected to the lever 28 by which the piston of the measuring` cylinder is moved, but is slidable through an aperture in the end of that lever, and a spring 32 is coiled on the rod 31 between the connection of that rod/130V- lever 5 will place the spring 32 under compression, which compression will exert itself later-to eflect the required movement of the a to transfer the filled cup from under the piston 22.
lA11 the movements of the machine are carefully regulated to be synchronous or timed in relation to the other movements dependent on them.
rl[`he entire operation of the machine may he enerally described as follows:
n deposit of a coin of the required size in the slot 11, 'connection is made in the manner described between the external handled lever 5 with the Operating shaft a in the machine and the various parts secured thereto. Downward movement of the lever 5, in the direction shown on Fig. 1, will draw downward the presentation plate 7 2 with its cup holding receptacle 7 5: Will express the eharged contents of the cylinder 18 through the elasticity of the spring 32, into the cup previously released from the ma azine and supported in position beneath: ill move the lever 80 to bring its end 81 into the position show in dot and dash lines in Fig. ll, Where it will, during the return movement, engage the downwardly turned end 55 and 'withdraw the supports 50 from the cup: Will impose the required tension on the Springs 15 and 63 to perform the other movements, and in the latter part of its movement will, efl'ect release of the bell crank lever 60, 61, to perform their service under the tension of the spring 63,'that is,
sition beneath charging cylinder' 18 to a the the aperture 711. and in the path of 'lrawn down plate 72.
rl`hereafter the handle 5 on being released will be carried up to its normal up er position hy the spring 12 independentof the op- 'eration of the internal mechanism .of the machine, the principal Operating lever 13 of 'which is latched at the downward limit of its movement., As explained the movement of the lever 28 which controls other movements will necessarily be slower under the action of the spring 32 owing to the resistance ofiered hy the' liquid bein expressed from the cylinder; but when t e lever 28 reaches the upper limit of its movement under the pressure of the spring 32, the bell cranlr lever 60, 61 is released and under the tension imposed on its sprin' V8.3 and checked I hy the air cushion in the tu e 67, the memher 57 ie moved slowly forward carrying the filled cup to the position ready for presentetion through the aperture 71. At the` conclusion of this movement the latch 76 1s released andthe lever 13 is free to move up under the action of the spring 15, lifting the lilled cup with it on .the plate 72. At the same time the rod 54k is drawn back by the end 81 of the lever 80 to release the filled cup from itslsupport on the members 50 and the member 57 and those supports 50 are withdrawn clear of the uplifting plate 72. Near the conclusion of this movement the after projection 56 carries with it the lower end of the lever 41, and operates the cup release mechanism to set free another cup from the magazine and deliverit into the supports 50 in position beneath the measuring cylinder 18.
While the lever 13 is moving up under the action of the spring 15, its movement is checked by the movement of the piston 22, recharging the measurin cylinder 18, the Operating mechanism of t e piston 22 being connected to the shorter arm 16 of 13.
When the lever 13 is latched at the down- Ward limit of its movement and the external handledlever 5, by which the lever 13 was carried down, moves toward its normal up- Ward position, it moves the tongue 8 od the coin in the chute extension 14 and the coin, which connects the two levers, falls into the cash receptacle.
l do not desire to be oonfined to the particular construction and manner of operation of the several parts of the machine, as set forth in this specification, or as illustrated in the drawings by which it is accompanied, as the same may require to be varied considerablyy to meet the requirements of manufacture: Further, the customary provision will require to be made for detecting and `rejecting an unsuitablecoin or for preventing the use of slugs.
