22 Claims.

This invention relates to coin controlled mechanisms such as are commonly employed in vending machines.

The primary object of the present invention is to generally improve coin controlled mechacontrolled mechanism which will accurately distinguish true coins from spurious coins, and which will not respond to the latter regardless of whether ferrous or non-ferrous, solid or washershaped, cardboard, sheet metal, or over-size or under-size as to diameter or thickness.

A more particular object of my invention is to avoid using the coin as a load transmitting element, and to instead employ the same simply to trigger and indirectly make effective a separate and independent load transmitting mechanism. With this arrangement the mechanism may, on the one hand, be designed for severe loads, and, on the other hand, may treat and handle the coin in a relatively gentle manner, making the detection of spurious coins more sensitive. Still another object of my invention is to provide trigger mechanism which must not only be actuated by a coin of accurate dimension, but which must be operated in proper time relation to the parts of the associated, mechanism, so that delay or mis-timing in the release of the trigger mechanism will itself prevent operation.

Another object of my invention is to prevent actuation of the trigger mechanism by inserting a wire or pick through the coin slot; and with this object'in view I provide a trigger lock for preventing movement of the trigger, this trigger lock being released by movement of a proper coin in the mechanism toward the trigger. Still another object of my invention centers about the stroke completion means intended to prevent the coin or/ and coin carriage from being moved back after only partial operation. Such stroke completion means, if always effective, may result in the mechanism being left in intermediate position by an idler casually playing with the operating handle. In accordance with a further feature and object of my invention, the stroke completion means is made ineffective except upon deposit and movement of a coin in the mechanism.

The delivery mechanism associated with the coin controlled mechanism for actually delivering goods to the purchaser may be of a type movable for successive deliveries by simply shaking the entire box or casing of the apparatus. One object of my invention resides in the provision of mechanism, specificially in the form of a normally engaged holding pawl or detent for preventing movement of the delivery system except through 5 operation of the coin controlled mechanism. During a part of the operating cycle of the coin controlled mechanism the detent is of necessity released or disengaged. It may thus become possible for a person to deposit a proper coin in the mechanism and to operate the same to only that point where the detent is disengaged, and to thereupon shake the casing in an endeavor to obtain a series of deliveries instead of only one delivery for the single coin. A further object of my invention is to prevent this possibility, and to this end I provide an additional safety stop which moves into stop relation with the mechanism when the detent is disengaged.

To the accomplishment of the foregoing and 20.

such other objects as will hereinafter appear, my invention consists in the coin controlled mechanism and the elements thereof and their relation one to the other, as hereinafter are more particularly described in the specification and sought 5 to be defined in the claims.

Fig. 13 is a section taken in the plane of the line !3l3 in Fig. 12.

Referring to the drawings, one form of my invention is shown in Figs. 1 to 9, and a second 55 form in Figs. 10 to 13. The coin controlled mechanism as shown does not include the coin receptacle nor the vending or dispensing apparatus responsive to the coin mechanism, for these may be of conventional type. In both forms of the invention the coin mechanism includes a front plate or escutcheon I2 adapted to be exposed on the vending machine and carrying a coin slot 14 and an operating handle l6, best shown in Figs. 1 and 2 of the drawings. The coin mechanism terminates with a driven gear I8 located at the back of the coin mechanism and best shown in Figs. 2, 9 and 12 of the drawings. It will be understood that an appropriate part of the vending machine mechanism is suitably geared to the gear l8, so that rotation of gear i8 results in the delivery or release of the article being sold.

As is usual with these devices, a coin is deposited by the customer in coin slot l4, and the handle I6 is thereupon operated, and it is the function of the coin mechanism to produce movement of the gear l8 in response to movement of the operating handle l6 if a true coin of proper dimension has been deposited in the coin slot, but to prevent movement of gear l8 if no coin or a spurious coin is deposited in the coin slot.

Referring now to Figs. 1 through 6 of the drawings, the handle I6 is secured to a pinion 20 meshing with a rack 22 formed at the bottom of a longitudinally 'reciprocable coin carriage 24. The coin carriage is normally urged to the left, as viewed in Figs. 1 and 3, by a spring 25 ten sioned between the carriage at 28 and the stationary frame at 30. Spring 26 restores the coin carriage to initial position, thereby placing the coin seat or recess 32 on the carriage in alignment with coin slot [4. At the same time the operating handle 16 is, of course, raised to the starting pdsition shown in Fig. 1.

When a true coin of proper dimension is deposited in slot l4, it rests on the coin carriage in a manner shown by coin 34 in Figs. 3 and 4, and movement of handle l6 thereupon causes the coin carriage with the coin to move toward the right, as viewed in Fig. 3. In the course of its movement, and preferably near the beginning thereof, the top edge of coin 34 bears against a trigger 36 disposed in its path and causes the same toswing outwardly.

The trigger mechanism further includes a shaft 38 and a stop finger 4!], the stop finger 40 and the trigger 36 both being fixedly secured to shaft 38 for simultaneous movement, as shown in Fig, 4.

Referring now to Figs. 8 and 9, the lower end of stop finger 4!) bears against the arm d2 of a first pawl 44, the pawl 44 being pivoted at 46 on an oscillatable pawl plate 8. Pawl 44 is normally urged in a clockwise direction into engagement with a single toothed wheel 53 by a spring 52, but is restrained against movement by trigger finger 40. This in turn is normally drawn to stop position by a spring 54 tensioned between stop finger 49, at the point 55, and a screw 58 on the stationary frame of the coin mechanism, the stop position being determined by a fixed abutment 60.

The single toothed wheel 59 is mounted on an extension or hub 62 formed integrally with pinion 20, and is keyed to pinion 29 by a key indicated at 64 in Fig. 2. Pawl plate 48 is oscillatable on extension 52. It will thus be evident that upon movement of trigger 36 outwardly by coin 34, the stop finger 40 is moved out of the way of pawl arm 42, permitting pawl 44 to engage the tooth of wheel 58. The continued rotation of wheel 50 with pinion 20 causes a counter-clockwise rotation of pawl plate 48, as viewed in Figs. 8 and 9.

Pawl plate 48 in turn carries a driving pawl or second pawl 66 pivoted at 68 and cooperating with a ratchet 10, the pawl being urged into engagement with the ratchet by a spring 12. The ratchet "i5 is, in the present case, provided with four teeth, it being contemplated that the vending machine be operated in response to a quarter of a revolution of the main driven gear i8. Ratchet i6 is preferably formed integrally with gear I8, as is best shown in Fig. 2. Gear I8 is preferably further formed integrally with an additional ratchet wheel wi l, the teeth of ratchet 14 being faced opposite those of ratchet l0. Ratchet 14 functions as a holding ratchet and cooperates with a detent 16 best shown in Fig. 9, this detent preferably behig formed integrally with the stop finger 46. It will thus be evident that actuation of the trigger mechanism by the coin releases detent i5 to permit rotation of gear l8, and releases pawl 44 to produce the desired rotation of gear [8.

The rotation of gear I8 is produced and accompanied by an oscillation of pawl plate 48. This pawl plate is restored to initial position by a spring '48 anchored at one end by stationary screw 8i! and at its opposite end on pawl plate 63 by means of a pin 82. The initial position of the pawl plate is determined by an abutment or stop 8t formed on the frame of the coin mechanism.

During the continued movement of the operating handle I 6, the coin carriage 24 is, of course, moved further to the right, as viewed in Fig. 3. During this continued movement the coin passes over a coin ratchet pivoted at 92 and normally held in elevated position by a spring 94. This ratchet necessitates completion of the operating stroke of the handle, for otherwise the coin is restrained against return movement by the ratchet. When the operating stroke has been completed, the coin is moved past the end of coin ratchet 90 and is thereupon released and permitted to fall downwardly into an appropriate coin receptacle via sloping track or guide 96, the coin receptacle being, in the usual case, positioned to the right and below the coin mechanism, as viewed in Fig. 3.

As so far described, it has been assumed that the coin deposited in the coin mechanism is a true coin of proper dimension. Further features of the present mechanism may best be described I with reference to attempted misuse of the machine. If the coin is over-sized as to diameter or thickness, it will not pass through the coin slot [4, and consequently cannot be employed. If the coin is under-size as to diameter, it will simply pass beneath the trigger 35 without operating the trigger. If the coin is undersize as to thickness, it will recline rearwardly in the manner indicated by the slug I 00 shown in Fig. 7, for the coin is supported at its lower edge in the seat or recess 32 and is further supported by only the pin I62 the tip of which is accurately located to hold a coin of proper thickness in an erect position. It will be evident from inspection of 7, that the slug 16L- wiil not bear against the trigger 36 until the coin carriage 24 is moved to the right a distance indicated by the spacing at the top of the figure. This is to be contrasted with the case of a true coin which, in the position shown in Fig. 7, would already be in contact with the trigger 36. There consequently is a lag or delay in the movement of the trigger, and this delay is taken advantage of to prevent effective coupling between the operating handle I5 and the driven gear or end gear I8. Referring to Fig. 8, the relative spacing and location of the stop finger 40, the pawl 44, and the single tooth of driving wheel 50, are so determined that with a true coin the pawl 44 engages the tooth 50 with but little clearance. When the trigger release is delayed, the pawl 44 is freed just after passage of the notch or tooth in wheel 50, and the subsequent continued rotation of driving wheel 50 is ineffective to move pawl 44 or pawl plate 48. Consequently a coin under-size as to thickness, like a coin under-size as to diameter, does not succeed in coupling or clutching the operating handle I6 to the driven gear I8.

If a ferrous or magnetic slug is inserted in the machine, it is disposed of by a magnet I04, best shown in Figs. 3, 4 and 6. The magnet is U- shaped, and its open end is disposed over the coin. Its closed end I06 is pivotally mounted on the frame between bearings I08 and H0. The magnet is normally held downwardly upon a stationary rest M2, forming a part of the frame, by a spring I I4.

At the beginning of the operating stroke of the handle I6, the magnet I04 is elevated from the position shown in Fig. 3 to the position shown in Fig. 6, so that if the slug 34 is made of ferrous metal, it is drawn upwardly in the manner shown in Fig. 6. This releases the lower edge of the coin from the seat 32 on coin carriage 24, and continued movement of the coin carriage simply brushes the coin from the magnet. The upward movement of the magnet is obtained by mechanism best shown in Fig. 8. The single toothed wheel or driving ratchet 50 is cut away as shown at II6 to form a cam surface in which rests the cam follower portion H8 of a lever I20 pivoted at I22. The upper end of the lever is bent at right angles to form a finger I24 which passes through a slot I26 and lies beneath the magnet I04. The relation of the finger I24 to the magnet H34 will also be clear from inspection of Figs. 3 and 6. It will be manifest that the initial rotation of wheel 50 with the operating handle I6 elevates lever I 20 which in turn elevates the magnet I04.

If the slug inserted in the machine is provided with a hole in the center, as is the case with a washer or a token, the slug falls back over the supporting pin I02, as is clearly illustrated by the washer-like slug I30 in Fig. 7. In this position the upper edge of the slug is far below trigger 36 and is incapable of tripping the same.

If the slug inserted in the machine is flexible, as is the case with cardboard, it will bend or yield about the supporting pin I02, as is illustrated by the slug I32 in Fig. '7, and will overcome the resistance of trigger 36, if at all, too late to cause engagement of the pawl and single toothed ratchet.

Return movement of the coin is prevented not only by the coin ratchet 90 and trigger 36 but also by a catch or stop I34 best shown in Fig. 5. This catch is formed at one end of an arm I36 pivoted at I38 and urged to the normal position shown in Fig. 5 by a compression spring I40. The stop finger I34 passes through a slot I42 cut in the frame plate, and the location of the stop finger will be evident from an inspection of Figs. 3, 4, and 6.

To prevent damage to the coin mechanism by are held tightly together in the mating or nested 10 relation shown in Fig. 2, by a bolt I52 the head end of which bears against a ompression spring I54 housed within the hub of the handle. It will thus be evident that upon excessive resistance to rotation of the handle, the handle will move 5 outwardly against the resistance of spring I54, permitting the teeth or bumps 48 to ride out of the mating recesses on pinion 20.

.A modified form of my invention is shown in Figs. 10 through 13, and will next be described. 20

One important respect in which the second form of the invention differs from the first resides in the provision of means to lock the trigger against improper movement, as, for example, by

a ,wire or pick inserted through the coin slot 25 and manipulated in an effort to move the trigger. For this purpose I provide a trigger lock I00, best shown in Figs. 11 and 12, which is disposed directly in front of the depending arm 240 mounted on the bearing shaft 38 of trigger 35. lock I 50 forms an integral part of a lever I232 pivoted at I64 and normally urged inwardly to the position shown in Fig. 11 by a compression spring I66. The innermost part I58 of lever I52 passes through a slot H0 in the rear wall I'I2 of 35 the coin mechanism. This part of the apparatus is largely analogous to the coin stop I34 mentioned when describing the first form of the invention, but in the present case the part I68 is greatly elongated to be effective during nearly all of the stroke of the coin and is tapered to act as a coin follower along which the coin on the coin carriage wipes during its movement and by which the lever IE2 is moved outwardly against the resistance of spring I66. When coin follower I58 is moved outwardly by the coin to lie flush with Wall I12 of the mechanism, the trigger lock itt is moved out of the path of arm 24%, thus permitting the latter to be tripped by the coin when the coin reaches the trigger.

The present modification of the invention also differs from that first described in completely eliminating the coin ratchet. The latter, while simple and effective for most purposes, is apt to become clogged and troublesome in the event of 5 someone dropping a paper clip or the like into the coin slot. In the present form of the invention, as will be manifest from an inspection of Figs. 10 and 11, the coin carriage 224 terminates at the coin seat 232, and has no ratchet associated there- 60 with, so that objects dropped in the coin slot fall readily from the coin carriage down chute 95 into the coin receptacle. In fact, most undersized slugs and improper objects fall from the coin carriage immediately upon deposit Without any movement of the coin carriage and without necessitating the assistance of coin follower IE8 or/ and trigger I36.

In the present arrangement completion of the stroke of the coin carriage is insured by pawl and ratchet mechanism including a ratchet I14 (see Fig. 11) formed on the side of coin carriage 224 near the end thereof, and cooperating with a pawl or detent I'I6 movable through a slot I'IS in wall.

I72 under the influence of a relatively light com- 75 Trigger 30 pression spring I80,detent I16being pivoted at I82. While it is important to lock the coin carriage against return movement when a coin is placed therein, it is actually undesirable to thus lock the same when no coin has been placed therein, for otherwise an idle bystander may move the operating handle to an intermediate position and there leave the same, thus blocking insertion of a coin by a following purchaser attempting to use the mechanism. To avoid this difficulty I interconnect the trigger lock mechanism with the stroke completion mechanism; and, specifically, I extend the lever I82 rearwardly to form a stop finger I34 which normally bears against a stop pin I86 formed on detent I18 (see Figs. 11 and 12). As will be evident in Fig. 11, the detent I15 is normally held out of engagement with ratchet H4, making the stroke completion means normally ineffective. Upon insertion of a coin, however, movement of the coin carriage forces the coin follower I68 outwardly and thereby releases detent I16 for engagement with ratchet I'M, thus preventing return movement of the coin carriage until its stroke is completed, at which time the coin passes coin follower I68 which immediately moves inwardly and thus again disengages detent I175.

It has already been explained in connection With the first form of the invention that unintended movement of gear I8 is prevented by an appropriate holding pawl and ratchet mechanism, this mechanism being specifically exemplified by ratchet 14 and detent 10, the latter being formed integrally with lever or stop finger 38. The present embodiment of the invention is similarly provided with a lock wheel or ratchet 214 with which mates a holding pawl or detent 216, the latter preferably being formed integrally with lever 240 (see Fig. 12). In the present case the Wheel 2% differs slightly in providing a positive lock against movement in either direction, instead of merely locking gear I8 against movement in one direction. This precaution is desirable when the delivery mechanism geared to the coin mechanism is susceptible of being operated in either direction, as by violently shaking the casing of the vending machine.

With such a delivery mechanism it may become possible for a purchaser to insert a proper coin and to only partially operate the handle or lever until the detent 16 or 218 is released, and to thereupon violently shake the vending machine while holding the operating handle against movement, in an effort to cause successive or continued delivery by the delivery mechanism, all in response to the insertion of only a single coin.

To prevent this possibility I provide an additional safety stop for limiting the rotation of the gear I8 (or related mechanism), said safety stop preferably being effective when the detent is disengaged. Referring to Figs. l1, l2 and 13 of the drawings, the safety stop in the present instance takes the form of a reciprocable stop pin I96 movable toward and into stop relation with lugs or projections I92 formed on the inner face of gear I8. Four such stop lugs or projections I92 are provided because in the present case gear I8 is designed for quadrant movement for each operation. The stop pin I90 is normally urged away from gear I 8 by a compression spring I 94 housed within a bushing I95 forming a part of or cast integrally with the back plate I12 of the mechanism. Spring I94 bears at one end against an enlarged head I98 on the stop pin, which in turn carries a cam follower pin 20!) the upper end of which bears against a camming surface 202 formed on one side of the coin carriage near the It will be noted from inspection of Fig. 11 that 5 during the first part of the movement of the coin carriage, the safety stop pin I90 is forced into stop position, thus preventing completion of even a quarter turn of gear I8. It is during this part of the movement of the coin carriage that the hold- 10 ing detent 216 is disengaged in response to movement of the coin trigger 30. Near the end of the movement of the coin carriage, the cam track or surface 202 is cut away, as is clearly shown in Fig. 11, thus permitting the safety stop pin 15 I90 to move away from gear I8 so that the gear may complete the desired quarter turn in response to movement of the operating handle. It is important to note, however, that the arrangement of the parts is such that during this last fraction of movement of the coin carriage the trigger 36 has already been released and holding detent 216 has already been moved back against the periphery of wheel 214. During the continued movement of gear I8 the wheel 214 moves past 25 detent 216, and at the completion of a quarter turn the detent automatically moves into the approaching notch on wheel 214, thus anchoring gear l8 against the possibility of further movement. There is consequently no point at which 30 gear I8 is free for continuous movement, because the safety stop is not disengaged until the holding pawl or detent has already been freed for active engagement.

The present form of the invention also differs in the arrangement used for elevating the magnet I04. Referring to Figs. 10 and 11 of the drawings, the coin carriage 224 is provided on its upper side with a camming projection 204 which is generally triangular in outline and which is so disposed as to bear against a part of the magnet, specifically the cross bar or sleeve 206. It is evident that the initial movement of the coin carriage causes cam 204 to bear against sleeve 206 and to thereby elevate the magnet I04, thus unseating and discarding ferrous slugs. This magnet elevating mechanism may, of course, be employed in the first form of coin mechanism also, but is especially convenient in the present coin mechanism in order to avoid interference with the stroke completion means and safety stop means.

With respect to both forms of the invention I may briefly point out that the device 2| 0, pivoted on the rear wall of'the mechanism, is simply an empty stop which moves into the path of the coin carriage and prevents the coin carriage from returning to its'initial position should the vending machine be emptied of its wares. Incomplete return of the coin carriage prevents insertion of a coin. I may also mention, in passing, that the bearing 2I2, forming a part of the rear plate I12 of the mechanism, is simply intended to receive a shaft carrying a gear which meshes with gear I8 and which forms a part of the delivery mechanism to which the present coin controlled mechanism is connected in a particular instance. The connection of the delivery mechanism to gear I8, or to any appropriate driven element corresponding to gear I8, may, of course, be varied as desired, in accordance with the requirements of the particular vending machine in which the coin mechanism is employed.

It is believed that the mode of constructing and using, as well as the many advantages of my im- 5 2,015,351 proved coin mechanism, will be apparent from the foregoing detailed description thereof. With a true coin of proper dimension, the coin is not used as a direct driving element for the transmission of force, but rather is simply employed to trip trigger mechanism, which in turn controls the coupling of the operating handle to the driven gear. This coupling mechanism may be made rugged and capable of transmitting considerable force between the operating handle and the driven gear. The coin is itself subjected to no mutilation. Spurious coins are ineffective to operate the mechanism, and the mechanism is sensitive to slugs under-size as to thickness, as well as to slugs under-size as to diameter. Ferrous slugs, washers,'flexible slugs, and the like, are all rejected by the mechanism.

The use of a trigger facilitates the detection of slugs, and in the present mechanism a time factor is introduced, necessitating operation of the trigger at exactly the right instant. In fact, the mechanism may, if desired, be adjusted to such hairline sensitivity that even a slightly thin but otherwise proper coin will be ineffective to operate the mechanism, and. this degree of sensitivity should ordinarily be avoided. In addition to the necessity for operating the trigger at the right instant, the trigger may further be provided with a lock,making it impossible to operate the trigger by a wire or pick inserted through the coin slot, this trigger lock being released only upon movement of a coin along a coin follower. The mechanism may be provided with stroke completion means with or without using the coin for this purpose, and the stroke completion means is ineffective in the absence of a coin. The delivery mechanism may be provided with holding pawl or detent mechanism, and additionally provided with a safety stop operative when the detent is disengaged and insuring against any possibility of shaking or otherwise moving the delivery mechanism through more than a single delivery cycle upon deposit of one coin.

It will be apparent that While I have shown and described my improved coin controlled mechanism in preferred forms, many changes and modifications may be made in the structures disclosed, without departing from the spirit of the invention, defined in the following claims.
