VENDING-MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 714,615, dated November 25, 1902.

Application filed March 3,1902. Serial No. 96.457. (No model.)

. To all whom, it may concern:

Be it known that I, EDWARD SHAW, a subject of the King of Great Britain and Ireland, residing at London, England, have invented Improvementsin Vending-Machines,of which the following is a specification.

This invention relates to improvements in vending-machines of the kind in which predetermined quantities of goods are delivered from bulk and in exchange for a proper coin, and pertains more particularly to that class having a common chute into which the articles of different classes are discharged, and

, inafter referred to.

more particularly to the construction shown and described.

Referring to the accompanying drawings, Figure 1 is a front elevation of my improved vending-machine. Fig. 2 is a rear View of the removable front portion of such machine. Fig. 3 shows, to a larger scale, a section on the line A A of Fig. 1. Fig. 4 is a section on the line B B of Fig. 3, illustrating a detail here- Fig. 5 is a section on the line C O of Fig. 2, showing in side elevation the coin chute and holder with adjacent parts. Fig. 6 shows in plan the parts represented in Fig. 5. Fig. 7 shows the parts represented in Fig. 5 in opposite side elevation thereto. Figs. 8, 9, 10, and 11 are cross-sectional views taken on the lines D D and E E of Fig. 7, F F of Fig. 5, and G G of Fig. 6, respectively. Fig. 12 is a section on the line H H of Fig. 3. Fig. 13 shows in plan the parts represented in Fig. 12. Fig. 14 is a plan of a detail to which reference is hereinafter made. Fig. 15 is an elevation of the weighing mechanism, showing an alternative arrangement for causing a variation of the center of gravity of the scalebeam. Fig. 16 shows the machine in front elevation with the removable front portion thereof removed. Fig. 17 is a diagrammatic view of the electric coin -operated switch, showing the circuit it controls. Fig. 18 shows the complete machine in side elevation. Figs. 19 andfZO are sectional detail views taken on the lines I I and J J, respectively, of Fig. 18. Figs. 21 to 26 are detail views to which reference is hereinafter made. Fig. 27 illustrates an alternative arrangement of mechanism whereby the revolution of the weighingbucket upon the completion of a weighing operation stops the goods delivery.

In a machine of the kind referred to and which is illustrated by way of example in the above-specified figures of the drawings there are a number of rotary compartments or drums each adapted to contain goods in bulk and mounted on an approximately horizontal tube or hollow axis 109, each drum being provided internally with buckets or scoops that pick up goods and drop them into a deliveryhopper leading into a common chute that conducts them to an automatic weighing device, and the actuation of the drums one at a time is efiected through coin-controlled mechanism, which actuating mechanism is put out of action by the tipping of the automatic weighing device.

.For the purpose of rendering the machine capable of delivering difierent weights of goods in exchange-for coins of difierent values the operation of the coin-holder of the I of greater value may cause an additional.

weight to rest on the scale-beam during the succeeding weighing operation. In the accompanying drawings one arrangement for this purpose is illustrated in which the machine is adapted to supply goods in exchange foreither of two coins of different diametersforexample, a halfpenny or a farthing. The coin-slot a, Fig. 1, leads into a short chute 17, Figs. 2, 5, 6, 7, and 10, the width of which is made greater above a certain depth than it is below-for instance, by forming at each side a ledge or shoulder c, Fig. 10. The farthing rests and slides within the narrow channel formed by and between the two ledges or shoulders c, and the halfpenny rests upon them and slides in the wider channel above them. The coinholder is formed as a disk d, having two eccentric peripheral grooves of different depths, the one, 6, adapted. to receive from the wider channel the hall-penny and the other, f, to receive from the narrow channel the farthing.

I The farthing-groove f is opposite the leverarm 9, rigidly connected to the short shaft h, geared at it to the transverse shaft m, carry ing the door n, Fig. '3, of the chute that conducts the goods to the weighing device and act uates the paper-delivery mechanism 0 and the clutch p g, which couples the external handle 4" to the drum-actuating means. The part clutch p on the outer end of the camclutch shafts is mounted so as toslide thereon and is pressed forward by a spring 75, Fig.

- 5, located between the clutch and a bearingtt is caused to oscillate.

each of the clutch members.

of the clutch.- shaft 8. For returning the transverse coin-operated shaft m to its normal position a curved leaf-spring 1; may be employed,one end beingsecured to afixed part to of the machine, the other end encircling a pin 00, fixed to the gear-wheel y, with which the pinion z on the transverse shaft m engages. The coin holders or grooves e and f are carried by the shaft 7", on which the operatingcrank r is mounted, and upon the rotation of said shaft the coin in holder will engage either the arm Z or g, and thus rotate the shaft 72. The outer end of said shaft carries a bevelgeark, ineshin g with the bevel-gear 75, carried by the shaft 'm, which operates the mechanism connected thereto. Carried by the shaft rm is asmall gear-wheel ,2, which meshes with the teeth carried by the disk y, whereby it The shaft m of the oscillating disk y carries a pinion 'm, which engages the circular groove member m and by means of which the clutch member q is moved upon the shaft 7" and made to engage the cooperatingmember mcarried by the shaft S, thereby coupling the two shafts together. The shaft S carries loose pinions 130, which engage the toothed periphery 131 of the cir- Y culargoods-receptacles.

to enter the cam-recess d and the clutch member 0, caused to engage. The cam-recesses d are located at different points upon the several disks 132, whereby the clutch members and their pinions which coact with the respective goods-receptacles will be thrown into operation according to the posi tion of the shaft K. 'The pointer 108 is connected to the shaft K. For instance, if the pointer is thrown to No. 2, as shown in Fig. 1, the coin-recess d of the disk 132, which controls the clutch members and pinion for operating No. 2 goods-receptacle, will be.

brought to a point opposite the adjacent end of its lever 133, thus causing the clutch members to engage. When the pointer 108 is turned to another index-number, the clutch members just operated and. all of the other clutches except the one to which the pointer is turnedwill be thrown out of operation. In Fig. 3 two of the clutch members and their cooperating mechanism are shown, and the clutch for goods-receptacle No. 2 is thrown into operation to correspondwith the position of the pointer in Fig. 1.

The halfpenny-groove e of the coin-holder d is opposite to a second lever 1, mounted side by side with the first lover you the same shaft h. This second lever 1 is loosely mount-- ed on its shaft, but has its boss formed with a slot 2, into which extends a pin 3, project-. ing from the shaft, the arrangement being such that on rotation of the coin-holder a halfpenny contained in the groove 6 therein will turn the lever 1 about the shaft it until the end of the said slot 2 comes in contact with the pin 3, when further movement of the lever 1 will carry with it the shaft h and cause the actuation of the parts connected therewith, but that upon the first-mentioned lever g and the shaft h being actuated by means of a farthing the pin 3, projecting from said lever-shaft h, will travel in the slot 2 of the secondly-mentioned lever 1, but will not actuate it.

To an arm 4 of the secondly-mentioned lever 1 is attached a wireor other flexible connection 5, which passes over suitably arranged guide-pulleyst and has secured to it at a point above the weight-arm 7 of the scalebeam an additional weight 8, arranged to be loweredso as to rest upon the said weight-arm upon the movement by the halfpenny of the loosely mounted lever 1. The additional weight 8 is caused to remain in its operative position during the succeeding weighing operation by the engagement of a spring-pawl with the loosely mounted lever 1. The spring-pawl (shown in plan to an enlarged scale in Fig. 14) may comprise an arm 16, mounted on a stud 17, fixed to the machinecasing, and having pivoted at its free end a spring pressed catch 18, adapted to engage the suitably-shaped end of the arm 4 of the halfpenny-lever 1. The arm 16 is held up against a stop 19 by a spring 20, coiled on the stud l7, and the arrangement is such that the catch 18 will yield and allow the arm 4 ofthe halfpenny-lever to pass it when the latter is pressed upwardly against it, but will become engaged with the projecting end of the arm 4 on the lever 1 during the reverse movement thereof and hold the said lever in its raised position until the curved leaf-spring o, that returns the entire mechanism to its original or normal state and which is more powerful than the spring 20 of the arm 16, is allowed to come into action. The effect of the additional weight 8 resting upon the arm 7 will be to cause a variation oft-he center of gravity of the scale-beam in such wise that the latter will not tip until a greater weight of goods has been delivered into the scale-pan.

Fig. shows an alternative arrangement, according to which the secondly-mentioned lever lis connected bya link 9 to one arm 10 of a bell-crank lever pivoted to a fixed part of the machine, the other arm 11 of which is connected by a link 12 to one arm 13 of a second bell-crank lever, also pivoted to a fixed part of the machine, whose other arm 14 has jointed to it a rod 15, that carries at its upper spring 23 and adapted to be operated by hand when the predetermined quantity of goods have been received in the receptacle by means of a knob or handle 24, fixed to one end of a spindle 25, forming the pivot of thebottom 22, and which spindle extends to the exterior of the machine. To prevent the delivery of the goods from the receptacle 21 before the proper quantity has been delivered thereto, the pivot-spindle 25 has fixed to it a tooth or ratchet-wheel 26, adapted to be engaged and held by a pawl 27, pivoted at 28 to the receptacle 21 and normallyheld out of engagement by a wire 29 or the like connecting it to an arm 30 on the coin-operated transverse shaft Upon the operation of the machine and the consequent partial rotation of the transverse shaft m the free end of the arm 30 descends, thus allowing the pawl 27 to become engaged with the tooth or ratchet-wheel 26 and remain so until the transverse shaft m is returned byits spring o to its normal posi tion.

To obviate goods getting caught between the closingdoor 'n of the trough or chute 31, which conducts them to the weighing device, and its seat 32, and thus preve ting it closing in an air-tight manner, a detent pivoted to a short spindle 34, carried by the front end of the chute 31, is adapted to engage an arm onthe door n, which is loosely mounted on the shaft m. When the shaft m is turned through the coin, a stop,consisting of a pin 36, fixed to the shaft, extending through a slot 37, formed in a pivot-lug on the door, carries the door at around. On the i return move: ment of the shaft m the detent 33holds back the door n until the pivoted bottom 22 of the delivery-receptacle 21 is opened, when by means of a forked arm 38on pivot-spindle 25 of its bottom engaging a pin 39, projecting laterally from one arm 40 of a lever pivoted at 41 to the delivery-receptacle 21, and whose other arm 42 is arranged in the path of a suitably-guided rod 43, connected to an arm 44 on the spindle 34, to which the detent 33 is fixed, the said detent 33 is disengaged from the projection 35 and the door 71. allowed to close under the influence of gravity, assisted, if required, by a spring or weight.

Below the delivery-receptacle 21 is a discharge-passage 45, leading to the exterior of the machine-casing, and within this passage is pivoted an open-bottomed slightly-conical paper-bag holder 46, which is normally held by a catch 47 in such position as to form a portion of the said discharge-passage. When the catch 47 is withdrawn, the bag-holder 46 is forced outwardly by a spring 48 into such a position that a paper bag, which may conveniently be of triangular shape and be delivered from the machine, can easily be fitted into the bag-holder 46 by the customer, the lowest point or corner of the bag then extending through the bottom thereof. When the bag is placed in the holder 46, the customer can push the holder back into its normal position, Fig. 3, where it will be retained by the before-mentioned catch 47, and in which position the goods upon leaving the deliveryreceptacle .21 will fall into the paper bag, which can then be withdrawn through the bottom of its holder by pulling the projecting point or corner of the bag. Between the pivoted bottom 22 of the goods-delivery receptacle 21 and the bag-holder 46 an inclined guard-plate 49,0r plates are fixed to prevent the delivery-receptacle being interfered with by hand. To release the catch 47 and allow the bag-holder to open, as above mentioned, the catch, which in the example is in the form of a vertically-sliding pin or bolt 47, pressed down by a spring 50" and having a beveled end, may be operated by a lever 51, one end being forked, so as to engage with suitable projections 52 on the catch, and the other end having a roller 53, located in the path of a spring-pressed pawl 54, pivoted to one arm 55 of a bell-crank lever, Whose other arm 56 is connected by a link 57 to an arm 58 on the coin -operated transverse shaft m, the arrangement being such that upon rotation of the transverse shaft m by a coin the pawl 54 strikes against the roller 53 and op-.

erates the catch-lever 51 so as to release its catch 47; but upon the return of the transverse shaft m to its normal position the pawl 54 yields and slides freely over the roller 53 of the catch-lever 51.

Loosely mounted upon the spindle 59 of the an endless chain 64, each link of which is formed with a slot 65, adapted to hold any coin which will effect the operation of the machine. The upper length of, the chain travels along the upper surface of a coinway 66. Simultaneously with the coin-produced IIO movement of the chain the previously-used coin is carried forward exactly a distance equal to the length of a link of the chain, and an unoccupied link is brought into a position at the end of a coin-chute 67, which receives the coins from the coin-holder d. The coins received from the said coin-holder rest on the coinway 66 and are carried forward in the chain-links. The tension of the. chain is maintained by suitable means. For instance, it may pass around a curved leaf-spring 68, near which is arranged a money-box 69, into which the coin falls at the desired time. In

. the front of the machine is a glass window 70, through which the weighing mechanism and other parts of the machine can be seen. The coin-chain 64 is arranged to travel just below this window, so that the coins as they travel to the money-box 69 can be seen, the length of chain being such that the last eight or ten coins inserted will always be exposed to view, so that if an improper coin has been inserted it can be seen. Within the machine maybe placed a notice (indicated at 72) ofiering a reward for information leading to the detection of any one fraudulently obtaining goods, and a lamp 73 may also be provided to illuminate the notice. The current for the lamp may be obtained from an accumulator 74, Fig. 16, the electric circuit being closed upon the insertion of a coin by means of an arm 75 on the transverse coin-operated shaft m, adapted upon the actuation of the shaft ure 79 being arranged behind to represent the organ-grinder, while the additional weight 8 may be in the form of a monkey, which will descend and rest upon the organ when the half-penny is placed in the slot and operates the mechanism. The parts of the rotatable drum 71 that will be visible through this window could be advantageously used for displaying advertisements.

The coin-chute 67, (see Fig. 8,) that delivers the coins to the coin-chain 64, may at the end nearest the coin-holder d be formed with a portion 80 of its bottom hinged and kept in position by a spring 81, so that should two coins be placed in the coin-slot of the machine in rapid succession and become pressed together in the mouth of the coin-chute its hinged bottom portion 80 will give and allow a coin to fall out of the chute Without damto be supplied to the drums. The paper-bag compartment 86 is controlled by a single lock, and this compartment does not give access to any other part of the machine, a partition or screen 87 being provided, as indicated in dotted lines in Fig. 2, so as to out off this compartment. The money box door 82 has a safety-lock, the bolt 88, Fig. 19, of which cannot be moved until a catch 89, actuated from the far end of the machine,is operated through a second safety-lock 90, that is a complex lock. The safety-lock bolt 88 is formed with a recess in which takes the toothed end of the catch 89, that is so weighted as to normally prevent the bolt 88 being moved.

A rod or bar 91, mounted in bearings 91, fixed to the casing 85, is at one end formed with an arm 92,that bears against the suitablyshaped top surface of the rear arm of the catch 89, and at the other end of the rod 91 is another arm 93, arranged in the path of the movable bolt of the lock 90. The bar 91 is provided .with a weighted arm 94, that normally tends to move the catch 89 so as to release the bolt 88, but is prevented from so doing by reason of its bolt bearing against the arm 93 (see Fig. 20) until the withdrawal of the said bolt. This insures that money cannot be removed unless the two locks are operated, and they cannot be operated simultaneously by one person. The long door 84, controlling access to the drums, can only be opened after a bolt consisting of two hinged portions 95 and 96 (operatedby means of a bell-crank lever 97, with handle 98 and link 99, from inside the money-box door) has been moved so as to release the hinged portions 95 96 from engagement with eyes 100 101, secured to the inside of the door. Thus an additional check is provided against tampering with the machine.

The goods-containing drums may each comprise a pair of dished metal plates having secured between their edges or rims a metal ring 102. Each of these rings may be stamped from a plate in one with the buckets or scoops 103, which are formed with recesses or depressions, Fig. 21, and afterward given a half-twist, so as to occupy the proper attitude for picking up the goods, (see Fig. 22,) the two dished plates and the metal ring 102 to form one drum being then arranged in proper relative positions, and by means of a lathe and suitable tools the edge or rim 104 of one dished metal plate, which for this purpose is made Wider than the edge or rim 105 of the other dished plate, is turned over the metal ring 102 and the edge or rim of the second dished plate,as shown in Figs. 23 and 24. The drum thus constructed has the teeth formed in its edge or rim by means of dies or punches in several successive or in one operation.

Connected to the receptacle end of the scale is a string 119, which has its opposite end connected to one end of an intermediatelypivoted lever 128. The other end of the lever is connected by a string 128 to the pawl 123. When the proper amount of goods is delivered to the receptacle and the scale has been depressed, the pawl 123 will engage the ratchet 124 and lock the goods-delivery mechanism and stop further supply of goods.

In the front of the machine is a window 106, through which can be seen samples of the goods to be sold, each kind being in a separate compartment provided with a'number or other index, a dial 107, having corresponding numbers or indexes, being arranged behind the pointer 108 of the clutch-cam shaft, which is so arranged that according to the number or index over which the pointer of the index rests that pinion-clutch will be engaged which will connect to the pinion-shaft the pinion of the drum containing goods of the kind displayed in the compartment bearing a corresponding number or index.

The inclined trough or chute 31, Fig. 3, within the hollow axis 109, on which the drums are mounted, may be perforated, so that as the goods roll down the trough they are sifted, and the hollow axis is at the rear end providedfwith a door 110, Fig. 18, whereby the accumulated dust and small particles that have passed through the trough or chute may be removed.

The chute may, as shown in Figs. 16, 25, and 26, be arranged to have afree end movement of, say, half an inch each time the main drum-operating pinion-shaft sis turned. On the back of the half-clutch p is a cam with one or more projections 111, which actuate through an arm 112 a rod 113, connected by an arm 114 and link 115 to one arm 116 of a bell-crank lever, whose other arm 117 is arranged to push back the chute 31 by means of a pin 118, projecting therefrom, and then to suddenly release it, so allowing it by rea son of its weight to jolt down. This insures that goods cannot permanently remain on the chute, but will be jerked down into the weighting device. In some cases the descent of the chute maybe assisted by a spring.

Fig. 27 illustrates an arrangement wherein instead of a cord 119, operated by the revolution of the weighing-bucket for bringing about the stoppage of the goods delivery, a light rigid connecting-rod 120 is employed,

said rod being connected to an arm 121 of a very delicate bell-crank lever, a horizontal arm 122 of which rests under the weight end 7 of the scale-beam. When the weight rises, the bell-crank turns, and the catch 123 engages the teeth 124, formed in the half-clutch pot the main pinion-shaft s, and the mechanism is thrown out of gear by the spring V, as heretofore described.

In some cases a musical box or the like may be geared to the cam-shaft s. Fig. 16 shows a musical box 125, that is driven by a cord or belt 126, that works in a groove formed on the periphery of the half-clutch p of the camshaft .9 and over a pulley secured to the driving-arbor of the musical box, so that each delivery of goods is accompanied by music.

The operation of my device is as follows:

A coin is first dropped into the slot a, and it passes down into the coin-holder e or f, whichever it may be, this depending upon the coin. The handle r being rotated carries with it the coin-holder, and said holder carrying the coin revolves, the coin engaging the arms carried by the shaft h and oscillating the the same. This shaft in turn oscillates the shaft in, which opens the door to the chute, locks the bottom to the receiving-receptacle, rotates the coin-receiving belt, completes the circuit for the electric lights, and also controls the bag-delivering mechanism. The shaft m carries a gear 2, meshing with the teeth carried by the disk y, thus oscillating the same, and said shaft upon which the said disk is mounted carrying a pinion meshing with the circular grooves upon the sleeve, whereby the clutch p is thrown in position and the shaft S started to rotate, said shaft carrying the pinions being provided with the friction-clutch and the means for throwing the desired pinion in operative engagement with the desired goods-receptacle, as heretofore more fully described. During this operation the goods are being discharged into the common chute and from thence to the scales, and when said scales go down the mechanism is thrown out of operative connection by the string 119 and the delivery of the goods stopped. The changing of the scales for different amounts of goods for the difierent coins has heretofore been fully described.
