Application April 15,

, 9 Claims.

This invention relates to electrically operated change-making, vending, computing, and control machines, wherein upon the insertion of coins of different denominations, coins are delivered from coin chutes containing coins of different denominations representing the difference between the amount of the inserted coins and an amount to which the machine is set or to which it is actuated.

A purpose of this invention is to provide a coinactuated control and change delivery mechanism wherein upon completion of the performance of certain functions an amount is established in the machine and change representing the difference between the amount established and the amount of coins inserted in the machine is mechanically discharged or delivered therefrom.

In the usual change-delivery and control machine (such as proposed in Mihalek Patent No. 2,491,900, dated December 20, 1949, with dispensing mechanism not shown), the amount of the function is established, and as a coin is inserted in the machine, the function is performed and the instrumentalities automatically operate to deliver the proper change. In some cases,

however, it is desired to first compute an amount after the desired coins are inserted and then deliver the proper change, and for this reason it is desirable to provide means for accumulating credit values representing the amount of the inserted coins until the performance of certain control functions is completed, and, during the completion of credit deducting functions, establish the amount and then deliver the correct change.

It is, therefore, among the objects of this invention to provide an improved coin-actuated control and change delivery mechanism; which ispused to receive coins of various denominations to establish a desired credit amount and provide control functions for any service function controlled mechanism (not shown) that is operative on a rate basis and performs a service, sale or like function; which may be actuated to return change amounting to the difference between the value of the deposited coin or coins and the value of the service control functions provided; which will, upon the deposit of coins therein, accumulate unit credits to the full value of the coins deposited; which will deduct unit credits from the accumulated credits in amounts equal in value to the value of the service control functions provided; which accumulates credit units by applying electrical impulses from a coin controlled impulse generator to the credit accumulating mechanism and utilizes electrical, impulses generated at a predetermined rate by a service controlled credit deducting impulse generator to deduct credit units corresponding in value to the value of service control functions rovided; which maintains the proper amount of change available 1947, Serial No. 741,492

- 2 for immediate delivery but will not deliver change prior to the completion and evaluation of the service control functions provided; which will return the entire value of the deposit if no credits are deducted; which will automatically terminate the service control functions provided in the etent the credits deducted become equal in value to the value of the credits established at the beginning of an operative cycle; which will automatically terminate one of the service control functions provided and then return to a zeroized -condition after any delivery of change in order to provide an accurate performance during the next operative cycle; which is simple and durable in and capable of a change delivering range from zero to several dollars in one cent variations.

Other objects and advantages will become apparent from a consideration of the following description and the appended claims in conjunction with the accompanying drawings wherein:

Figure 1 is a view showing a front elevation of the change delivery and control machine illustrating a machine of a typical design and showing the relative positions of the coin deposit slots for coins of different denominations, and with parts broken away showing the deposited coin chutes and the money box from which the deposited coins may be removed.

Figure 3 is a diagrammatic view illustrating a plurality of coin controlled impulse generators such as controlled by deposited nickels, dimes, quarters and half-dollars, with the electric integrally associated circuit therewith, wherein a number of credit accumulating electrical impulses are generated corresponding with the number of cents of the coins deposited.

' Figure 4 is a cross-section through one of the generators illustrated in Figure 3, showing the friction clutch elements through which the actuatingcam disc associated therewith is rotated and a stop pin by which the cam disc is held from rotation until a coin controlling the operation of 50 the generator is inserted in the associated coin deposit slot. c

Figure 5 is a detail taken on line 5-5 of Fi ure 4 showing a side view of the actuating cam disc with the shaft thereof shown in section.

Figure 6 is a diagrammatic 'view, illustrating a plurality of credit accumulating and credit de-' ducting and change carrying discs which are rotated in a credit accumulating direction through] credit accumulating means by impulses generated by the coin controlled impulse generators for construction, positive and accurate in operation of the credit accumulating and credit deducting and change carrying discs shown in Figure 6, showing in particular the disc for carrying nickels.

Figure 9 is a detail taken on line s-s of Figure 1 illustrating a combination of solenoids through which the credit accumulating and credit deducting and change. carrying disc I2! is rotated in the credit deducting direction through a ratchet wheel and shaft with each impulse generated by the service controlled credit deducting impulse generator.

Figure 11 is a detail showing a section, on line il--ii of Figure 8. through one of the credit accumulating and credit deducting and change carrying discs illustrating in particular a disc for carrying two coins, such as nickels, wherein one coin only may be positioned adjacent change delivery means at a time.

Figure 12 is a detail illustrating a section similar to that shown in Figure 11, showing one of the credit accumulating and credit deducting and change carrying discs coin receptacles in which a plurality of coins may be positioned adjacent change delivery means at a time.

Figure 13 is a detail showing a section through one of the credit accumulating and credit deducting and change carrying discs taken on line lI-il of Figure 8, the disc being shown as roa pin 3! similar to the one as illustrated in Figure 5, generating nve credit accumulating impulses to cause the penny change carrying disc I23 to be rotated in a credit accumulating direction for a complete rotation and thereby impart a partial rotation to nickel change carrying wheel I24 in credit accumulating direction so as to position a nickel in position adjacent the coin kicker i (Fig. 13) later to be described. Should the value of a service control function provided be, as an illustration, 3 cents, credit deducting impulses generated at a predetermined rate by the service controlled impulse generator contacts I", I and ill will cause the two above mentioned change carrying discs to be rotated in the credit deducting direction whereby the nickel change carrying disc I24 will remove the nickel formerly presented for delivery as change and the penny change carrying disc I23 will position two pennies adjacent the kicker I positioned or combined with this credit accumulating and credit deducting and change carrying disc, wherein two pennies in change may be delivered therefrom as will hereinafter appear.

In the design as illustrated in the drawings, the actuating cam discs l2 are mounted each on one of four separate shafts it, which are rotated continuously by a motor is (connected to any suitable electric power supply) through a train of gears 20 as illustrated in Figures 1 and 2, between rotatably amxed clutch elements 2i and 22 mounted on an associated shaft as shown for one combination thereof in Figure 4 and held in frictional contact with the disc by spring 23 pos tioned between collar 24 on the shaft and the back of one clutch element and holding the clutch elements and the disc against lock nut 25. The

' shafts are rotatably mounted in separate beartated ninety degrees from the position shown in Figure 8, illustrating the solenoid actuated change delivery kicker associated therewith.

Referring now to the drawings, wherein like reference characters indicate similar parts, the change delivery and control mechanism of this invention is illustrated as being incorporated in a casing II with a plurality of coin receiving slots in a plate II on the face of the casing. with a plurality of actuating cam discs l2 and credit accumulating and credit deducting and change carrying discs I! in the casing and with a change receiving tray II at the lower part of the front of the casing positioned to receive all coins that may be kicked or delivered from the change carrying discs It.

In the operation of the machine, a coin, such as a nickel. is inserted in the nickel slot II and the coin drops downward through one of the chutes ll, illustrated diagrammatically in Figure 3, until it arrives at a position between two electrical contacts l2 and I wherein it completes a circuit that causes an actuating cam disc l1, having five projections or lobes on the periphery thereof, to be released and rotated for one complete rotation by drive means later to be described. The rotation of cam i1 closes the normally open credit accumulating impulse genings 26 in upwardly extending element 21 of a base 2| and the outer ends of the shafts are held by separate screws 2! with conical shaped points 30 that extend into sockets ii in the ends of the shafts and are secured by separate lock nuts 32 as shown for one combination thereof in Figure 4. The actuating cam discs l2, therefore, are fricticnally coupled to their associated shafts which rotate continuously but the discs are normally held against rotation by stop pins 33 which extend into sockets 34, provided one adjacent and one in each cam disc. when a coin of the proper denomination is inserted in an associated coin deposit slot located in plate Ii, the stop pin 33 of the associated credit accumulating impulse generator is withdrawn from the socket 34 in the associated cam disc by an associated solenoid ll, such as illustrated in Figures 3 and 4, whereupon the associated actuating cam disc is released and is rotated by the turning shaft ll associated therewith, through clutch elements such as 2i and 22. The coin makes only a momentary connection between the contacts 42 and I2 energizing the solenoid 33 to withdraw the stop pin 32 from the socket 24. The circuit is broken as soon as the coin passes from between the contacts 42 and 42 and the stop pin is returned to holding position illustrated in Figure 4, by a spring I, to stop the disc vafter one revolution thereof. In the design shown in Figures 3 and 5. a disc I! is illustrated as having ten cam points similar to the cam of the distributor ofa motor vehicle, and each time one of these points It passes a contact pin 30 attached to one end of a contact arm 55, normally open contacts 58, ll and 40 as numbered in Figures 1, 3, 4 and '7 are crating contacts II, I and ll five times. through is alternately closed and opened, intermittently U wa completing circuits therethrough and generating ten credit accumulating electrical impulses as wires I8, 'II and I21 in Figure 3 are alsoshown in schematic form in Figure 7, electrically connected therewith.

As illustrated in Figure 3, the solenoids 88 by I which the stop pins 88 are actuated are included in a circuit wherein contacts 42 and 48 in D- posite sides of the coin chutes I8 are connected to a battery 44. The contact 42 is connected by a wire 45 to one terminal of the solenoid 35 with the other terminal of the solenoid connected by coin chutes to release the associated actuating cam discs for coins of different denominations. Therefore; when a nickel is deposited in the coin slot I5, it will fall down the chute I8 associated therewith and cause the cam disc I1 to be rotated by the associated drive means for one revolution, actuating the contacts therewith and generating five credit accumulating impulses; when a dime is deposited in the coin slot 58, it will fall down the chute I 8 associated therewith and cause the cam disc 3| to be rotated by the associated drive means for one revolution, actuating the contacts therewith and generating ten credit accumulating impulses; when a quarter is deposited in the coin slot 5|, it will fall down the chute I6 associated therewith and cause the cam disc 53 to be rotated by the associated drive means for one revolution, actuating the contacts therewith and generating twenty-five credit accumulating impulses, and when a half-dollar is deposited in the coin slot 52, it will fall down the chute I8 associated therewith and cause the cam disc 54 to be rotated by the associated drive means for one revolution, actuating the contacts therewith and generating fifty credit accumulating impulses. In Figure 4, one contact arm is shown as a spring arm projecting from an insulating block 58 and one each of contacts 48 and H are also shown as spring arms projecting from the block 88, these spring arm contacts are normally open until operated or actuated by an associated actuating cam disc.

The ratchet wheels 8 I, associated one each with each change carrying disc shaft 88 and that rotates each associated shaft and disc in a clockwise or credit accumulating direction, are actuated by pawls I88 on armatures I88, the armatures being pivotallyconnected to the pawls by pins H8 and pivotally mounted at the opposite ends on brackets by pins III. The armatures I88 are influenced by solenoids I I2, as shown for one combination thereof in Figure 10, that draw the armatures I88 upward when the solenoids II2 are energized by electrical credit accumulating impulses and during the times that the solenoids II2 are not energized the springs I2I force the armatures downward, and the springs I22 holding pawls I88 in engagement with ratchet wheels 8|, except when solenoids H3 are energized which is during the time of impulse genoration by contacts I81 and I88 .or 282 and 2". later to be described.

- The ratchet wheels I4, associated one each with each change carrying discs shaft 88 and that rotates each associated shaft and disc in a counter-clockwise or credit deducting direction, are actuated by pawls I8 on armatures II4, the armatures being pivotally connected to the pawls by pins I I 8 and pivotally mounted at the opposite ends on brackets II8 by pins III. The armatures I I4 are influenced by solenoids I I8, as shown for one combination thereof in Figure 9, that draw the armatures II4 upward when the solenoids II8 are energized by electrical credit deducting impulsesand during the times that the solenoids II8 are not energized the springs II8 force the armatures downward and the springs I28 holding pawls 18 in engagement with ratchet wheels I4. except when solenoids I2 are energized which is during the time of impulse generation by contacts and H, later to be described.

The credit accumulating and credit deducting and change carrying discs it are fixedly mounted, by any desired means, on the lower ends of vertically disposed shafts 88 above a horizontally disposed partition 88 in the casing I8, and the ratchet wheels 8| through which the shafts and discs are rotated in a clock-wise or credit accumulating direction, are positioned on the shafts 88, and afllxed thereto by any desired means, below the bearings 82, and below the ratchet wheels 8I are the ratchet wheels I4 that rotate the change carrying discs and their associated shafts, as they are also afllxed one to the other by any desired means, in a counter-clockwise or credit deducting direction. The number of teeth of each ratchet wheel corresponding with the number of divisions of the disc fixedly mounted on a shaft therewith and the teeth of the ratchet wheels are in proper alignment with said disc divisions. Vertically disposed coin chutes or tubes 88, angularly spaced one division counter-clockwise from coin kickers I48, as shown in Figure 8 for the nickel carrying disc I 24, extend upward from the upper surfaces of the discs and the upper surfaces of the discs are provided with coin carrying receptacles or recesses such as numbered 84, I28, I38, I3I, I82, I88 and I34 in three of the change carrying discs, said recesses or receptacles corresponding with the number and denominations of coins handled thereby. The depth and diameters of the recesses varying as necessary in order to deliver proper change if necessary, also, the number of the divisions in some of the discs varying for the same reason.

The outer surfaces of the discs I3 are provided with indentations 88, and rollers 88 on arms 81 that are pivotally mounted at points 88 and resiliently held by springs 88 against the outer surfaces of the discs and are positioned to register with the indentations 88 to releasably restrain the rotation of the discs in between the times of the step by step rotative movements or rotation of the discs. Each of the discs I8 has on its periphery one or more projections to close contacts to establish or complete circuits to be hereinafter described. The disc designated as I24 in Figure 8, for example, and designed to position forv delivery as change one nickel is also provided with the projections I88 and IN which actuate normally open contacts I82 'and I88 of switch I84 located adjacent the disc, and normally open contacts I88 and I88 of switch I81 also located adjacent this change carrying disc. The depth of the coin carrying recesses in the upper surfaces of the coin carrying discs determines the number of coins carried and positioned for delivery as change thereby. As a matter of information in Figures 6, 11, and 12, the depth of the coin carrying recesses or receptacles varying in the different discs. The disc I24, illustrated in Figures 6, 8, 11 and 13 provides means for carrying only one coin in each of the two recesses I23 and I30 as this disc will never need to position for delivery as change more that one nickel, whereas in the disc I23, the recess I3I carries one penny, the recess I32 carries two pennies, the recess I33 carries three pennies and the recess I34 carries four pennies. The dime carrying disc I2! is likewise provided with four recesses, three of which are indicated by the numeral 34, that increase in coin capacity similar to the penny carrying disc I23, also, the half-dollar carrying disc I2. is provided with recesses, not indicated by a numeral, that progressively increase in coin capacity, with respect to the change delivery kicker means I48 associated therewith and adjacent thereby at zero position, in the direction of credit accumulating movement of the disc.

At least one blank or zero reference division is necessary in all of the change carrying discs in order that the mechanism may be zeroized or operated so that no change is positioned for delivery and also m order that control means may be operated, later to be described.

In the schematic diagram illustrated in Figures 6 and 7, the contacts 55, 4| and 43 that are closed by the cam points of the actuating cam disc I2 are, as previously explained, connected with the wires III, II and I2! in Figure 3 and are shown in Figures 1 and 3 as adaptedto be actuated by any of the cam discs I2 which are rotated by the motor I 9 (connected to any suitable power supply) through drive gears as shown in Figure 2. When a coin of the proper denomination is deposited in the mechanism, the credit accumulating impulse generator associated therewith will start operating, as previously explained, upon closure of the normally open contacts 5!, H and 4'; the first contact to be engaged by contact ll will be contact H which will complete a circuit from the main current supply wire 33 through wire 32 to terminal 6|, from terminal II through coil 51 to terminal I, from terminal 35 through wires 36, 61, coil 33, wire ll, contact It, contact H, and, from the contact H the circuit extends through a wire II to a solenoid I2 positioned to actuate a pawl 13 to disengaging position with respect to the teeth of a ratchet wheel I4 mounted on an associated change carrying disc shaft. From the solenoid 12, the circuit extends through similar solenoids adjacent to the different change carrying discs, being connected through wires I5. 16. I1 and II. From the last of the solenoids 12 the circuit extends through wires 13 and 13 to a wire an and the wire extends to the wire 64 of the main current sup- P y. thereby disengaging all the pawls 13 from contact with the teeth of the ratchet wheels I4 to allow rotation of all the change carrying discs in a clock-wise direction when the solenoids II2 associated therewith are energized.

The relays 34 are provided with centrally disposed armatures "and electromagnets II are positioned on the opposite sides of the armatures from the electromagnets 33 so that alternative energization of the electromagnets or solenoids l3 and 33 causes the armatures to move to one side or the other to condition the associated circults for the rotative actuation of the change carrying discs I24, I25 and I26 in either a credit accumulating or a credit deducting direction. Therefore or furthermore, upon closing of the contacts H and 55, a circuit is completed through wire II, through wires II and 62 to one side of three electromagnets 83 each on one side of double acting magnetic relays 34 and from the other side of the electromagnets 83 the circuits are completed through wires and the wires 33 or II, through wire 80 to the wire 64, the wire II being connected to wire 63 through the closed contacts 4| and '55, wires III, 61, 66 and 62 and through the electromagnets or solenoid windings l3 and 51 in series circuit therewith. Thus, the three armatures 81 of the three similar relays 34 are in contact with the three contacts I and the associated circuits are conditioned for the rotative actuation of the change carrying discs I24, I25 and I26 in a credit accumulating direction. With the electromagnets 83 in the circuit with the credit accumulating impulse generating contacts the change carrying discs will be rotatively stepped in the credit accumulating direction by the electric impulses generated thereby through means as will hereinafter appear.

As previously explained herein, upon the rotation of the actuating cam disc I2, contacts H and are first closed. This operation causes all four of the pawls 13 to be disengaged from contact with the teeth of the four ratchet wheels I4, thus making it possible for the shafts 33 and their associated change carrying discs to be rotated in the clock-wise or credit accumulating direction. Also, closure of contacts H and 55 causes the three armatures 31 of the three relays 34 to contact the three contacts I 40, as previously described. Upon the closure of contacts 55, H and '40, the armature I09 which actuates the change carrying disc I23 in a clock-wise or credit accumulating direction, as illustrated in Figure 6, is actuated by a solenoid H2 and the solenoid is energized with each electric impulse generated by the coin controlled credit accumulating impulse generators, as shown in Figures 3, 6 and 7, to rotate the disc I23 a number of rotative steps corresponding to the value in cents of the deposited coins. As illustrated in Figures 3, 6 and 7 wherein the contact 40 is connected by a wire I2I to one terminal of a solenoid II2 associated with disc I22 and the opposite terminal of that solenoid is connected by a wire I28 to the wire III which is connected to the current supply wire 34. The current supply wire 63 is connected to the contact 40 through the now closed contact II, the wire II, relay coil 68, wires 61 and 66, relay coil 51 and wire 62. The circuit is thereby completed through that solenoid II2 associated with the change carrying disc I23 and actuates the associated credit accumulating ratchet wheel 3| through the pawl III! and armature I09 associated therewith, thereby rotating the associated shaft 39 and disc I23 clockwise through an angle of seventy-two degrees for each impulse generated by the credit accumulating impulse generators contacts 63, H and 40. As the contacts 55, H and 40 continue to generate a sufllcient number of impulses the disc I23 continues to be rotatively stepped in a clock-wise direction, a projection I 35 thereon moves seventy-two degrees with each rotative movement of the disc and after the disc has received four rotative movements the projection I35 is in position so that when the fifth rotative movement is accomplished, the projection III will have engaged normally open transfer contact I36 which engaged contact I31 and completed a circuit through the solenoid II2 of the ratchet wheel pawl combination associated with the nickel change carrying disc I24, causing the disc to have been rotatively moved ninety degrees in the credit accumulating direction. The contact I31 is connected to the main current supply wire 63 through one wire I38 and a circuit from the contact I36 goes through one wire I39 to one armature 81, which being held in contact with one contact I40 by one relay coil 83 as previously described, is in contact with one contact I40 and that contact I40 is connected by one wire I4I to one terminal of the solenoid I I2 associated with the nickel change carrying disc I24. The other terminal of the solenoid II2 associated with this disc I24 is connected by one wire I42 to the main current supply wire 64 through one of the wires 86 and wire 80. Every other rotative stepping movement of disc I24 will have caused one of the projections I or IOI thereon to have closed normally open transfer contacts I05 and I06 and this will have caused disc I25 to be rotatively stepped one step, by the similar solenoid H2 and electrical circuits associated therewith, and every fifth rotative stepping movement of disc I25 will have caused the projection thereon, similar to projection I35 on disc I23, to have closed normally open transfer contacts associated therewith, similar to contacts I06 and I05 of disc I24, and this will have caused disc I26 to be rotatively stepped one step by the similar solenoid H2 and electrical circuits associated therewith. This series of operations continues as the credit accumulating impulses are generated and presents for delivery as change coins equal in value to the value of the deposited sum.

The combinations and series of operations as hereinbefore described will rotate the credit accumulating and credit deducting and change carrying discs I3 in a clock-wise direction, wherein after four pennies are positioned for delivery as change, the next credit accumulating impulse is effectively transferred to the nickel carrying disc to position for delivery as change one nickel, and after nine cents are presented for delivery as change, the next impulse is effectively transferred to the dime carrying disc to position for delivery as change one dime, and after fortynine cents are positioned for delivery as change, the next impulse is effectively transferred to the half -dollar carrying disc to present a half-dollar in position for delivery as change. This sequence will continue until the sum of $2.50 has been deposited in the coin deposit slots. Each rotative stepping movement of the penny carrying disc carries it through an angle of seventy-two degrees as it is divided ito five divisions. Each rotative movement of the nickel .rrying disc carries it through an angle of ninety degrees as it is divided into four divisions. Each rotative stepping movement of the dime carrying disc carries it through an angle of seventy-two degrees as it is divided into five divisions. Each rotative stepping movement of the half-dollar carrying disc carries it through an angle of sixty degrees as it is divided into six divisions. All of the ratchet wheels, as previously described, having a number of teeth corresponding to the number of divisions of the change carrying disc associated on a shaft therewith.

Referring now to Figures 6 and '1, the control instrumentalities provided as well as those used in the mechanism are illustrated as relays 58, 69, I65 and204 with their armatures in the positions 10 assumed when the change carrying discs I3 are zeroized or are in rotative positions with a blank space of each disc adjacent the four coin kickers I46, as a circuit from wire 64 extends through wire I16, relay coil I15, wires I11, I18, I19 and I60 and all of the closed contacts similar to and such as I45 and I44 adjacent disc I23 as they are in a series circuit therewith and from contact I44 the circuit extends through wire I8I to wire 63, completing the circuit and causing relay coil I15 to hold the armatures I82, I94, 20I and I63 of relay 69 in the positions as shown. With armature I82 held open with respect to the associated contact I83, no credit deducting operation can occur as will hereinafter be described. With armature I94 heldclosed with respect tothe associated contact I95, a circuit is completed from wire 63 through wire 62, coil 51 (holding the armature 59 open with respect to the contact 60 of relay 58 to prevent the operation of change delivery means, later to be described), wires 66 and I98, now closed armature I94 and contact I95, wires I96 and I91, relay coil I12, wires I99, 200 and which is connected to wire 64 thereby completing a circuit through the coil I! relay I65 and holding the armature I66 of that relay in the position as shown so that any circuit in series with wire I61, armature I68, contact I13 and wire I66 will be subject to control thereby and also, any circuit connected through wire I10, contact I1I, armature I68 and Wire I61 would be subject to control thereby. With the armature 20I of relay 69 held open, as shown, with respect to the associated contact 202 the circuit from wire 63 through wire 201, now open armature 20I and contact 202, wire 208, now closed contact 205 and armature 203, wire 206, relay coil I69, wires 200 and 80 to wire 64 will be open, releasing the armature I68 of relay I65 from magnetic influence oi the relay coil I69 so that it will be under magnetic influence of relay coil I12, as shown. With the armature I63 of relay 69 held open, as shown, with respect to the associated contact I64 any circuit in series therewith through wires I6I and I62 will be subject to control thereby. The relay coil 66 in relay 69 is connected in series with the credit accumulatingimpulse generating contacts, as previously described, in order that all the armatures of relay 69 will be held in the positions shown during the time of credit accumulating impulse generation by the contacts 55, 4I and 40.

In the first cycle of operation of the mechanism, the credit accumulating impulses generated, corresponding in number to the value of the coin or coins deposited will cause the change carrying discs I3 to berotatively stepped in the credit accumulating direction and position for delivery as change a coin or coins equal in value to the value of the deposited sum, the credit accumulating impulses generated will also .cause relay coil 68 of relay 69 to hold the armatures of relay 69 in the positions shown in Figure 7 during the time of credit accumulating impulse generation. When any one or more of the four credit accumulating and change carrying discs I3 are not at zero position, that is, when any one or more than one of the change carrying discs are not presenting at least one zero reference division adjacent the coin kickers I46, the projection on the Periphery of said any one or more than one of the discs similar to or such as projection I35 of disc I23 and projections I00 or IOI of disc I24, will be moved away from engagement with any one or more than one of the four contact.

combinations similar to or such as contacts I44 and Ill adiacentdisc ill or contacts "I and Ill A adjacent disc III. This condition will open the circuit through the coil Ill of relay ll as follows, from wire ll through wire I'll, coil Ill, wire I'll to any one or more than one of the open contact combinations referred to above as they are connected in a series circuit through wires Il'l, Ill, I'll, Ill and Ill to the wire ll. Therefore, after the credit accumulating impulses cease flowing through the coil ll, which is connected in series with the credit accumulating impulse generators contacts ll, ll and ll to prevent the movement of the armatures Ill, Ill, Ill and Ill of the relay ll during the time of credit accumulating in the mechanism so that the control means provided will not be actuated at this time, the armatures Ill, Ill and Ill of the relay ll will be released from the magnetic influence of coils Ill and ll to allow them to return to normally elem positions with respect to their associated contacts ill, "I and Ill for armatures Ill, Ill and Ill and armature Ill will be allowed to return to normally. open position with respect to the contact Ill associated therewith, thereby opening the circuit from wire ll through wire ll, coil l1, wires ll and Ill, now open armature Ill and contact Ill, wires Ill and Ill, coil I'II, wires Ill, Ill and ll to wire ll thereby releasing armature Ill of relay Ill from magnetic influence of coil III to allow coil Ill the controlling influence, as will hereinafter appear.

After a credit has been established in the mechanism and the armatures of the relay ll have been released from magnetic influence of coils Ill and ll. as previously described, a circuit is open from wire ll through wire ll, coil ll (releasing the armature ll so that it can engage contact ll of the relay ll to allow operation of change delivery means if no credits ar being deducted, later to be described), wires ll and Ill to now open armature Ill and contact Ill, through wires Ill and Ill, coil Ill, wires Ill, lll and ll to wire ll thereby releasing the magnetic influence of relay coil ill on armature Ill, and, a circuit is completed from wire ll through wire I", armature Ill and contact Ill now closed, wire Ill, normally closed contact Ill and armature Ill, wire Ill, relay coil Ill, wires Ill and ll to wire ll, energizing relay coil Ill so that the armature Ill thereof will engage contact "I and provide a primary electrical control means for any service function controlled mechanism or device that is operative on a rate basis. As a provisional illustration, the wires Ill and I'll may be connected in an operating circuit of a long-distance dial-telephone system so that when the circuit is completed by actuation of the armature Ill to engagement with contact III the telephone service may be commenced. Electrical switching means such as wire I", armature Ill, contact I" and wire Ill are also providedtobeusedif desired.

In addition to the above described control means after the armatures of the relay ll have been released from the magnetic influence oi coils Ill and ll, as previously described, the wire Ill, contact Ill, armature Ill and wire Ill of relay ll can provide a closed circuit for control purposes that may be used to directly or indirectly commence the operation of the credit deducting function in the mechanism. As a provisional illustration, the motor Ill and cam afllxed to the shaft thereof shown in Figure 7 for the operation of normally open credit deducting impulse 12 similar in structure to contacts ll,'.li and ll, could be directly connected to any suitable power supply in the circuit of which wire Ill, contact Ill, armature Ill and wire Ill would control. These credit deducting impulses are produced at a predetermined rate corresponding to the value of the service provided by any service function controlled mechanism operative on a rate basis and under secondary control of the mechanism herein disclosed, and said credit deducting impulses also corresponding in value to the value 0! service control functions provided by the mechamism herein disclosed as will hereinafter appear.

Operation of any service function controlled mechanism operative on a rate basis, such as an amusement device, long distance telephone, or equivalent device, as previously describedherein, influencing or causing actuation of the motor Ill periodically closes normally open contacts Ill and Ill during the time the controlled service mechanism is in operation. thereby completing circuits to the solenoids ill of the ratchet sssemblies illustrated for one combination thereof in Figure 10, drawing the pawls Ill away from the ratchet wheels lI, and thereby disengaging the credit accumulating and change carrying discs Il from clockwise rotation. Operation of motor Ill is timed and controlled by the operation of the service function controlled mechanism so that it will cause the credit deducting impulse generating contacts Ill, Ill and Ill to generate a number of credit deducting impulses corresponding to the value of service provided. and relay ll does not operate betweencurrent impulses generated'by contacts Ill, Ill and Ill. The contact Ill .is connected by a wire Ill to a wire Ill which extends to one terminal of the solenoid I ll associated with disc in and the other terminal of this solenoid is connected through the similar solenoids III in series circuit therewith by wires III, III, Ill and Ill and the wire Ill is connected to the wire ll which extends to the main current supply wire ll through the wire ll. The'circuit is completed through the armature ill, the wires I'll, Ill and through the now closed contact Ill and armature Ill to the wire Ill which is connected to the other main supply wire ll through the wire ll, relay coil ll and wire ll. The disengaging solenoids Ill, therefore, hold the pawls Ill away from the ratchet wheels lI so that the change carrying discs Il are ready for rotative stepping in the credit deducting direction. The armature Ill is, as hereinbefore described, in contact with the contact Ill during this operation.

The contact Ill also completes a circuit through the wires Ill, Ill and a wire IIl through the solenoids ll which are connected to the wire III by wires Ill, and the opposite terminals of the solenoids ll are connected by wires III, III and Ill to the wire ll that carries the circuit to the main current supply wire ll. This operates the relays ll, wherein the armatures II are actuated to engage the contacts Ill. The contacts Ill of the relays ll are connected by wires III to the solenoids Ill which actuate the armatures I ll and pawls II to rotatively step the succeeding discs Ill, Ill and Ill in the counter-clockwise or credit deducting direction through shafts ll and ratchet wheels ll when the circuits prepared by closure of contacts Ill are subsequently completed by closure of contacts similar to or such as Ill and Ill or Ill and Ill by cam projections similar to or such as Ill and Ill or III generating contacts I", Ill and Ill, which are 1| or a preceding disc. The relays ll disposed be- 13 tween discs I23 and I24 and between discs I24 and I25 and between discs I25 and I26 are, therefore, similarly controlled and circuits are prepared by contacts I43 to energize the deducting solenoids II8 for a succeeding disc when a. circuit is completed by the closure of contacts similar to or such as contacts I85 and I86 by a cam projection of a preceding disc. The opposite terminals of the solenoids II8 associated with discs I24 and I25 are connected by wires 2I8 and 2I9 to the main current supply wire 54 through the wire 88, and the solenoid I I8 associated with disc I26 is connected by a wire 228 to the wire 19 through which it is connected to the wire 64 through the wire 88.

The circuit for solenoid II8 associated with disc I24 is completed, as will be noted in the diagram shown in Figure 6, through the armature 81, the

wire I39, the contacts I36 and I31, the wire I38 and the main current supply wire 63. The contacts I31 and I36 are closed by the cam projection I35 as the disc I23 is rotated.

The disc I23, which is rotatively stepped during the closure of contacts I81 and I89, upon their actuation by motor I88, as previously described, is rotated in the counter-clockwise or credit deducting direction by its associated shaft 89, ratchet wheel 14, pawl 13, armature H4 and solenoid H8, and the solenoid II8'with this disc I23 is, therefore, directly connected by a wire 224 to the contact I89 which engages the armature I81, the opposite terminal of this solenoid II8 being connected by the wire 225 to the wire 223 and from there through the wire 88 to the main supply wire 64. It will, therefore. be observed that during credit deducting, the credit deducting and change carrying discs I3 are rotated in the counter-clockwise direction to reduce the value of a coin or coins positioned for delivery as change, with the disc I23 moving one step through an angle of seventy-two degrees with each electrical credit deducting impulse generated and succeeding discs I24, I25 and I26 rotated counter-clockwise one step upon each closure of contacts similar to or such as I36 and I31 or I85 and I86 of a preceding disc, and if the operations are continued to use up the entire value of the deposit, the zero reference divisions of the discs or at least one zero reference division of each disc will be returned to positions adjacent the coin kickers I46, causing the relay 69 to operate and remove the electric power from armature I81 as armature I82 and contact I83 will now be open, terminating the credit deducting functions and the control functions provided by the mechanism.

The construction of one of the change carrying discs is illustrated in Figures 8, l1 and 13 and it will be noted that the upper surface of the disc extends under the coin tube 93 with the change carrying recess I29, in Figures 8 and 11, contiguous with the lower end of the coin tube 93. In the disc I24 illustrated in Figures 6, 8, 11 and 13, which may be designated as the nickel change carrying disc, two recesses I29 and I38 are provided in two opposite divisions upper surfaces as taken on line II--II Figure 8 and the two zero reference divisions or blank spaces are provided at the other two opposite divisions of this disc I24 as taken on line I3-I3 Figure 8. As either one of the recesses I29 or I38 arrives at a position under the coin supply tube 93, having nickel coins therein, one nickel will drop from the tube into the recess, and when the other recess is disposed directly under the coin supply tube another nickel will be received and carried by the change carrying disc I24. As the disc is rotated through an angle of ninety degrees from the position shown in Figure 8, one of the recesses will be aligned adjacent one change delivery kicker I46, as shown in Figure 13, which is normally held away from the disc by one spring I41 positioned under one head I48 thereof and which is actuated for kicking change from the disc I24'by one solenoid I49 when it is necessary to deliver one nickel in change as illustrated in Figure 13. Figure 12 is a detail showing a section through the coin carrying receptacle I32 of disc I23 wherein two pennies are carried. The discs I23, I25 and I26 are also provided with change delivery kicker means similar to the one associated with disc I24, and they are also provided with associated coin supply tubes 98. As hereinbefore described, as the change carrying discs I3 are rotated in the credit accumulating direction the value of the deposited coin or coins will be presented in position for delivery as change and as the change carrying and credit deducting discs I3 are rotated in the credit deducting direction the value of the coin or coins presented for delivery as change will be decreased.

In the event the change carrying discs I3 are not returned to zero positions, with one zero reference division or blankspace of each disc positioned adjacent the coin kickers I46, at the conclusion of a service operation or in the event no credit has been deducted after a credit has been established in the mechanism, a change delivery and zeroizing function is initiated by closure of manually operated change delivery switch I14. With the normally open service controlled credit deducting impulse generating contacts I81. I89 and I98 and also the normally open credit accumulating impulse generating contacts 55. 48 and 4| open, the circuit is broken through the solenoid 51 of relay 58 which releases the armature 59, whereby the armature 59 engages the contact 68 and the circuit is completed from the main current supply wire 63 through the wire 62, relay coil 51, now closed contact 68 and armature 59, wire I58 through the four solenoids I49 and from the solenoids through the wire I5I, now closed switch I14, solenoid I52 and wire I53 to the wire 88 which is connected to the other main current supply wire 64. Therefore, as the switch I14 is closed, under conditions as above stated, a circuit is completed through the four solenoids I49 and the four coin kickers I46 are actuated to kick coins from all coin carrying receptacles or recesses positioned in the paths of actuation of the elongated heads I54. Therefore, change representing the difference between the credit accumulated and the credit deducted will be delivered or change representing the credit accumulated will be delivered if no credit has been deducted. The brackets I55 and the openings I56 in the centers of the under sides of the change carrying discs are designed to allow the coins delivered as change to pass from the recesses of the discs down the coin chute I51 to the change receiving tray I4 on the front of the mechanism. The tray may be provided with a hinged cover I58 mounted on the front I59 of the casing through a hinge I68.

The relay 58 is a slow-release type, so the. as long as a current or impulses flow through the windings of the solenoid 51 the armature 59 will be held away from the contact 68 in order to prevent the circuit being completed to the solenoids I of the coin kickers adiacent all the discs I! when the switch ill is closed. This is necessary to prevent operation of the change delivery means during the times that either the credit accumulating or the credit deducting functions are taking place, and also to prevent operation of the change delivery means during the time that the discs ii are positioned at zero or with a blank space of each disc positioned adjacent the change kickers I46, as a current will be flowing through solenoid 51, as previously described, at this time.

Closure of switch I14 completes the circuit through solenoid I52 and draws the armature 228 of relay 204, whereby it contacts the contact 221 and closes a circuit through the solenoid "2 of relay I65. The contact 221 is connected by wire 228 to the main supply wire 62 and the armature 226 is connected by wire 22! to the wire I" which is connected to one terminal of the solenoid I12 and the other terminal of this solenoid is connected by the wires i" and 200 to the wire 80 which is connected to the main current supply wire 64. At the same time, the solenoid "2 causes opening of the armature 202 and contact 205, whereby the circuit to the solenoid I" is broken as one end of solenoid I" is connected through wire 206 to armature 203. This operation terminates the control functions provided by armature I68, of relay I68, and the associated contact I'll.

Shortly after the change delivery means are operated the armature is of relay 58 will again break the circuit through contact II, as coil II is in series with the change delivery circuit, in order that the change delivery kickers I" will be withdrawn from the discs I! by the associated springs I" so that the discs can be aeroized or rotated counter-clockwise to refill the emptied coin carrying recesses and return a zero reference division or blank space of each disc to positions adjacent the kickers I46, and to operate the control functions provided by the mechanism to the positions as shown in Figures 6 and 7, as previously described.

Energizing the soleoid I52 by closure of switch I'll also draws the armature I93 into contact with contact 230 closing a circuit from now closed armature I82 and contact I" through wires Ill and I92, now closed armature I and contact 220, solenoid I 9| wire 22l, armature 232 which is intermittently operated by a cam driven by motor 233 to intermittently contact contacts Ill and 234 to generate the zeroizing credit deducting impulses. From the contacts 225 and 224 the circuits extend through wires 23! and 22' to contacts 242 and 24! which are now closed with armatures 242 and 2" and from there the circuits are connected in parallel to contacts Ill and Ill through wires 23! and 231. The relay 2 is also a slow-release type, and, therefore the armatures 226, I92, 240 and 242-and contacts 221, 22., 2 and 242 will remain in closed positions and armature 203 and contact 2.5 will remain in open position as long as current impulses flow through the solenoid m, and the reroizing impulses will continue to flow through this solenoid until all of the change carrying discs I! are returned to zero positions with a zero reference division or blank space of each disc positioned adjacent the coin kickers H6. The continuously running motor 228 is connected by wires 2 and 245 to any suitable source of electric current. when the change carrying discs II are returned to zero positions the relay ts will be operated, as previously described, wherein the armature I82 and contact 1| a coin or coins which will be received by the i I'll will be opened thereby breaking the circuit to armature 232. This will cause de-energization of relay 2, wherein armatures I, 2 and 242 and contacts 2", 2H and 2" will open and remain open, breaking the circuits from armature 222 and contacts 23! and 224 until another zeroizlng cycle is in progress. Also, armature 220 and contact 221 will open, allowing now closed armature I94 and contact I" of relay 6. control over solenoid "2 of relay I65, as armature 2.] and contact 202 of relay 6! will now be open the now closed armature 203 and contact 205 of relay 2 will have no control over solenoid I" of relay I", therefore, the armature I68 will be held in the position as shown in Figure 7 until another controlcycle is provided.

The elements may be used in combination with equipment or may be incorporated in a machine, or may be provided in a simple unitary casing, such as shown in Figures 1 and 2, and the casing may be of any Practical size, shape or design. In the design shown, the casing is provided with a front door 2 attached by a hinge 241 to the upper end of the casing and held by a lock 2 at the front. The door provides access to the coin tubes 93 and associated parts. The plate ll having the coin deposit slots therein is positioned at one side of the casing, wherein the coin chutes I extend downward in a compartment 2 in one slde'of the casing, and a money box or drawer 250 provided with a lock if desired is located in the lower section of the compartment 2 and positioned to receive all coins deposited in the coin deposit slots after they have dropped through the chutes it and theassociated contacts 42 and 42.

The control and change delivery mechanism of this invention is used to collect the charges, deliver the change if necessary and provide control functions for any equipment operative on a rate basis that serves a sales, service or like purpose. The instrumentalities are caused to operate by an electrical impulse or series of electrical impulses that are sentor set up by pairs of contacts positioned in opposite sides of the coin chutes, wherein separate coin chutes are provided for coins of different denominations, such as nickels, dimes, quarters and half-dollars. and with the chute of each coin deposit slot provided with contact points and with the contact points connected through a circuit to release an associated actuating cam disc for one revolution thereof, with the disc having a number of cam projections thereon corresponding with the number of cents of the deposited coin. a number of electrical impulses corresponding with the number of cents of the deposited coin will be generated as the disc makes one complete revolution. Each impulse generated is equivalent to one cent accumulated in the credit accumulating cycle of operation.

As the credit accumulating impulses are used to rotatively step the change carrying and selector discs of the mechanism, the discs I! are rotated to store the total number of cents wherein the credits accumulated may be deducted or spent with the equipment in combination with which the mechanism may be used. The credit deducting function is accomplished by electrical contacts generating impulses of electrical current, one for each cent deducted, to rotatively step the change carrying discs I! so as to deduct credits for so much service, sale or like value and position for delivery as change if necessary 17 person inserting the coin or coins in the coin deposit slots of the mechanism and associated equipment which may be used in combination therewith.

Brief statement of operation In order to carry the device through a brief illustrative cycle of operation, let it be assumed that the device is connected to a service instrument, such as a long distance system telephone, charging and thereby deducting credits at a constant or a varying rate for time used. Let it be further assumed that coins to the value of $2.50 are deposited and include one nickel, two dimes, one quarter and four half-dollars deposited in the order named.

Any suitable means may be incorporated with the mechanism, such as a sheet of printed instructions for operation, to limit the total number of coins deposited during an operative cycle and to insure that the coins are deposited one at a time in succession.

Now let it be assumed that the credits deducted for the telephone service rendered is $1.32 and that change amounting to $1.18 is delivered or returned.

The first coin deposited being the nickel deposited in the nickel slot will close the circuit through contacts 42 and 43 in the nickel chute and energize the solenoid 35 to withdraw the stop pin 33 from the five lobed nickel registering cam I1. After momentarily closing the contacts 42 and 43 the nickel passes through the chute to the coin drawer 250 and the cam I1 makes one complete revolution whereupon the stop pin 33 re-enters the socket 34 in the cam and holds the cam against further rotational movement. When the two dimes are successively deposited in the dime slot the ten lobed cam 31 will be given one complete revolution for each dime in the same manner. When the quarter is deposited, the cam 53 having twenty five lobes, will be given one complete revolution, and when the four half dollars are successively deposited the cam 54, having fifty lobes or projections, will be given one complete revolution for each one of the four half dollars deposited.

When the cam disc I1 makes a complete revolution it closes the switch contacts 40, M and 55 five times in rapid succession. Closing of contacts 4| and 55 energizes the solenoids 12 of all of the credit deducting solenoid assemblies, moving the pawls 13 away from the ratchet wheels 14, thereby freeing the discs to rotate in a clockwise or credit accumulating direction. Closing of the contacts 55 and H also energizes the electromagnets' 83 of the three magnetic relays 34, moving the armatures 81 of these relays into engagement with the associated contacts I40 so that the circuits of the credit accumulating solenoids I I2 will-be conditioned for successive credit accumulating rotation of the three discs I24, I25, and I26 as the credit accumulating capacity of each preceding disc is used up. The circuits through the armatures 81 being successively closed by rotation of the change carrying discs to successively close the associated switches such as the pair of transfer contacts I36 and I31 associated with the penny carrying disc I23 or such as the pair of contacts I05 and I06 associated with disc I24.

When the discs I23, I24, I25, and I26 are all in their zero position with a blank space of each disc adjacent the kickers I46, all of the switches corresponding to the contacts I44I45 operatedby the disc I23 are closed, energizing electromagnet I15 of relay 69 to maintain the control switch I63--I64 open, the switch I94-I95 closed and the switch 20I--202 open to maintain armature I68 controlling the outside circuits through wires I66, I61 and I19 in its position as shown contacting contact point I13. All of the disc operated switches similar to transfer switch I36I31 operated by the penny carrying disc will be open and only the credit accumulating solenoid driving the penny carrying disc can be energized.

Closing of the contacts 55 and 49 by the cam disc I1 applies current impulses to the solenoid II2 associated with the first or penny credit accumulating disc I23 to impart five rotational steps of 72 degrees each to this disc. The disc I23 successively moves groups of one, two, three and four pennies to position adj acent the change delivery kicker I46 and upon the fifth movement closes the contacts I36 and I31 so that the fifth current impulse effects the operation of the two solenoids II2 respectively actuating the disc I23 and the disc I24. This moves the penny disc I23 to present its zero reference division to the associated change delivery kicker and open the associated switch contacts I36-I31, and moves the nickle disc I24 to present one nickel to its associated change delivery kicker.

A credit of five cents has now been established and may be withdrawn either as change or service or partly in service, and partly in change.

Closing of the contacts 40 and 4| with the contact 55 also energizes the electromagnet 51 of the relay 58 moving the armature 59 away from the contact 60 to open the normally closed relay switch and simultaneously energizes electromagnet 68 of relay 69 moving armature I62 away from contact I83 to open this normally closed switch of relay 69. Relays 58 and 69 being both slow release relays, the above mentioned switches will remain open during a complete revolution of any one of the cam discs I1, 31, 53 and 54.

Opening of the switch in relay 58 places all of the solenoids I49 operating the change delivery kickers or plungers I46 out of circuit so that these kickers cannot be moved to interfere with rotation of the credit accumulating discs or to deliver change while the credit for a deposited coin is being established in the mechanism.

Opening of the switch including armature I82 and contact I63 in relay 69 interrupts the circuit to the credit deducting mechanism including the contacts I81, I89 and I90 operated by the motor I89 and to the zeroizing mechanism including the contacts 232, 234 and 235 operated by the motor 233, so that no credit deducting or zeroizing operation on the credit accumulating discs can take place during the credit accumulating operation incident to the deposit of a coin in the mechanism.

When rotation of the cam "disc I1 terminates, the above described relay switches close and the switches of the relays 94 open. We now have in the mechanism an accumulated credit of five cents and a nickel is held by the disc I24 in position for delivery as change by the associated kicker upon manual closure of the switch I14.

Next, a dime is deposited and the ten lobed cam disc 31 will be given one complete rotation generating ten current impulses through the conductor I21 to the solenoid H2. The penny disc will make ten more steps. At the conclusion of the first five additional steps of the penny disc the contacts I36 and I31 will again have been closed l9 imparting the fifth impulse to the nickel disc moving this disc one step and to the dime disc through the nickel disc operated switch moving the dime disc one step to present one dime for delivery as change, the nickel disc operated switch now being open.

As the credit accumulating solenoid is further pulsed the penny disc continues its step by step rotation and at the tenth impulse of the dime controlled ten lobe cam 81 the penny disc again closes its associated switch I88-I81 so that the tenth impulse moving the penny discs zero reference division to zero position is transfered to the nickel disc moving the nickel disc one step to present a nickel for change.

Insertion of the next dime imparts ten more steps to the penny disc. two more to the nickel disc, and one more to the dime disc, establishing a credit of twenty-five cents and presenting two dimes and a nickel for discharge as change.

Insertion of the quarter imparts twenty-five additional steps to the penny disc, five more to the nickel disc, and three more to the dime disc. The third additional step of the dime disc completes a total of five steps and closes the associated transfer switch so that the last impulse generated by the twenty-five lobed cam 88 is trans-' ferred to the half-dollar carrying disc I28, imparting one step to this disc and positioning a half dollar for delivery as change.

The penny, nickel anddime discs zero referimpulses corresponding in number to the cents value of service provided.

Closing of contacts I81 and I88 energizes all of the solenoids III of the credit accumulating solenoid assemblies for freeing the credit accumulating discs to rotate in a counter-clockwise or credit deducting direction and through wires 2I82I5 completes a circuit through relay coils 88 to close contacts ll881, thus preparing cir cuits to be subsequently completed by closure of contacts similar to or such as I88I81 or IDS-I08.

Contact I81 is connected to relay 88 through contacts I82 and I88 to maintain contacts 58 and 88 open so that change cannot be withdrawn during the period of service operation.

ence divisions are now returned to positions adv jacent the kickers opening the associated transfer switches and a credit of fifty cents will now have been established.

Deposit of the first half-dollar will impart fifty additional steps to the penny disc leaving it at blank or zero position, ten additional steps to the nickel disc leaving it in blank or zero position, five additional steps to the dime disc returning it to blank or zero position, and one additional step to the half-dollar carrying disc and will move this disc one step to present two half-dollars for discharge. A credit of one dollar is now established and two half-dollars are presented in position for delivery as change. v

Deposit of the three more half-dollars will act to advance the half-dollar carrying disc one step for each half-dollar deposited so that a final credit of $2.50 is established and five half-dollars are positioned for return as change.

Assumin now that, instead of pressing the button switch I14 to return the change, the depositor utilizes the $1.32 worth of service mentioned above. Since only coins valued at five units or multiples of five units can be inserted,,when the final credit has been established, all of the switches corresponding to the switch including the contacts I and I85 associated with the penny disc I23 will be closed except the corresponding switch associated with the half-dollar carrying disc I26. Electromagnet I15 will be de-energized and contacts 55, 48 and 4| will remain open, thus de-energizing the electromagnet 68 causing switch I82--I83 to close. switch His-I84 to close, completing the outside circuit through wires IGI and I82 and switch 20I282 to close and switch I84I 85 to open, de-energizing electromagnet I12 and energizin electromagnet I88 to swing armature I88 into engagement with contact "I and efiectuate the second outside circuit.

The outside device is now in operation and controlling the motor I88 so that it periodically closes the contact armature I81 with the contacts I88 and I88 to establish credit deducting electric Normally closed contacts I82 and I88 will remain closed since electromagnet 88 is de-energized by opening of the contacts 58, 48 and ll. Electromagnet I18 is also tie-ener i ed at this time.

Closing of contacts I81 and I88 during the credit deducting operation will close a circuit through coil II8 to step the penny disc counterclockwise. closing upon the first step thereof contacts I88I81, thus completing a circuit through wire I88 and contacts 81- 488 to the stepping magnet II8 of the nickel disc I24. to step the latter counterclockwise, thus closing its associated contacts I88I88 to complete a circuit to the stepping magnet II8 of dime disc I25, which will similarly close contacts to complete a circuit to the stepping magnet II8 of the half-dollar carrying disc I28. The first impulse caused by closing contacts I81 and I88 will, therefore, effectively go to the penny. the nickel, the dime and the half-dollar carrying discs deducting solenoids, moving the half-dollar disc back one step to present four half-dollars, the dime disc back one step to present four dimes, the nickel disc back one step to present a nickel and the penny disc back one step to present four pennies in position I for delivery as change and opening the associated transfer contacts.

The next impulse will move only the penny disc and when the penny disc has stepped five times it will have returned to zero position. During the sixth step of the credit deducting operation the penny disc I28 will again close transfer contacts I 38-431 and the nickel disc will be moved back one step deducting a nickel. The next five steps of the penny disc will bring up a nickel and remove a dime. This continues until forty-nine cents have been deducted and another impulse is then efi'ectively transferred to the half-dollar disc deducting fifty cents.

When the deduction of $1.32 has been completed. the coins positioned for delivery as change will be two half-dollars, one dime, one nickel and three pennies.

After the credit deducting impulses cease due to opening of the circuit through wire I88 by any suitable means, such as normally open service .controlled credit deducting impulse generating When the switch I14 closedit also energizes an electromagnet I52 which closes four pair of normally open contacts I88288, 248-2, 282-248 and 228-421, and it also opens one pair of normally closed contacts 28828I.

3i spear/1o With the closure of contacts 226-221, electromagnet I12 is energized to cause the Outside circuit normally maintained by armature I68 and contact I1I to be disconnected as the electromagnet I69 is now deenergized due to opening of contacts 203-485.

i Closing contacts 242-443, 240-24I and I93- 230 puts into operation a zeroizing mechanism presently to be described and energizes a holding electromagnet I9I which keeps these contacts closed until the zeroizing operation is completed even though the button switch I14 is released.

Shortly after the change is delivered relay coil 51 will open the circuit through armature 59 and contact 60, by actuation thereof, to allow the withdrawal of the coin kickers so that the change carrying discs can be zeroized or rotated to present a zero reference division or blank space of each disc adjacent the change delivery kickers. The credit accumulating and credit deducting and change carrying discs will not now be in their blank or zeroized positions and it is neces" sary to automatically return them to their blank positions or to zeroize the mechanism in order that the correct credits will be established and I the correct change delivered upon the next operation of the mechanism.

For this purpose a continuously operating zeroizing motor 233 with a cam on the shaft thereof is provided and periodically moves a contact 232 into engagement with two contacts 234 and 235, which are similar in structure and function to contacts I81, I89 and I90.

The contact 232 is connected through normally open contacts 230 and I93 and the normally closed contacts I82 and I83 to one side of the power supply. When the button switch I14 is closed, energizing electromagnet I52, contacts 242-243, 240--24 I, I93-230 and 226-421 are closed, as explained above, and are held closed by the holding electromagnet I9I energized by the closing of the contacts I93230, 240-24I, 242--243 and 232-234, 235. Contact 232 is now impulsing the deducting solenoids II8, electromagnet I9I being a slow release type.

Contact 234 is now connected to conductor 224 leading from the credit deducting contact I89 and contact 235 is connected to the conduc tor 2I0 leading from the credit deducting contact I90.

Operation of motor 233 will thus continue the step by step reverse movement of the credit accumulating and credit deducting and change carrying discs until all of the discs have been returned to the previously described zero positions.

When this occurs, all of the contact pairs corresponding to the pair of contacts I44 and I45 operated by disc I23 will be closed. These contact airs are connected in series with electromagnet I15 and when all are closed this electromagnet is energized, opening contacts I82 and ing of contacts 203205. If the entire deposit were usedup the discs I23, I24, I25 and I26 would return to their blank or zero positions immediately energizing electr. magnet I15, discontinuing both outside circuits. The discs being in blank position, no change can be delivered and, the switch I82I83 being held open, the zeroizing mechanism cannot operate.

The mechanism is now zeroized and ready to go through another cycle of operation similar to the one described hereinbefore.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
