Krysiak, 92 Harral Ave., Bridgeport, Conn. Filed Feb. 10, 1959, Ser. No. 792,363 6 Claims. (Cl. 1941-99) This invention relates to a coin selector for telephones, dispensing machines, and similar devices, and has for an object to provide a simple and effective device which will separate good coins of the denominations of ten cents, five cents and twenty-iive cents from spurious or bad coins, or Aso-called slugs.

It is also an object to provide a device of this character which will distinguish ybetween a-nd separate these coins of different sizes and values and discharge them through separate exits from the device for operating control of different coin-.controlled apparatus.

Another object is to provide a device which will separate the diierent sizes and values of coins from all kinds of spurious or bad coins, s'uch, for example, as coins of baser metals such as lead or brass, or coi-ns containing iron or magnetic material, as well as discs of light metal or paper or like material, and will direct them into diferent chutes or similar passages for directing good coins to a coin-controlled mechanism, such, for example, as a telephone or article dispensing device, and tol direct the spurious coins or so-called slugs to a separate container or to eject them from the machine.

Another object is to provide a construction of this character in which the good coins of the three diiferent sizes and values are separated from each other and the spurious coins or' so-called slugs by rolling action only of the coins along runways past various selecting devices.

Still another object is to provide a device of this character capable of separating the three coins of diierent sizes and values from each other and from spurious coins or slugs, which is devoid of bouncing anvils and pivoted deflectors or similar coin separating devices, so that the coins have a rolling motion only and the forward motion of the coins is controlled in the runways so that the velocity of the coins as they pass selecting devices along the various runways will attain a speed in accordance with that required for proper selec-tion.

Still another object is to provide a device of this character which is of very simple construction and will occupy a minimum of space, so that it can be manufactured at relatively low cost and will not require a large space in the machine in which it is employed.

A still further object is to provide a device of this character in which there is no mechanism to be operated or shifted as a coin is inserted in the device to thus provide resistance to insertion of the coin, but the inlet opening is a free opening or passage permitting the coins to pass freely into the machine.

Still another object is to provide a device for separatin-g these diierent values and sizes of coins from each other and from the spurious coins in which at no time is a coin or slug retained in the separator, requiring that it be later ejected or removed, but each passes directly through and is ejected from the device.

With the foregoing and other object-s in view, I have devised the construction illustrated in the accompanying drawings forming a part of this specification. It is, however, to be understood the invention is not limited to the specific details of construction and arrangement shown, but may embody various chan-ges and modifications within the scope of the invention.

In these drawings:

FIG. l is a front elevation of the device;

FIG. 2 is an edge view looking toward the left of FIG. l;

FIG. 3 is a vertical section substantially on line 3--3 of FIG. l;

FIG. 4 is a bottom edge view;

FIG. 5 is a detail longitudinal section;

FIG. 6 is a vertical section through the separating passage for dimes or ten-cent pieces, the plane of the section being substantially on the line 6-6 of FIG. 3;

FIG. 7 is a similar section through the selecting passageway for five-cent pieces, the plane of the section being substantially on the line 7-7 of FIG. 3;

FIG. 8 is an edge View thereof looking from the right of FIG. 7;

FIG. 9 is a section through the passage for twentyfive-cent pieces, the plane of the section being substantially on line 9--9 of FIG. 3, and

FIG. l0 is an edge view looking from the right of FIG. 9.

The device shown in the drawings is designed to separate the three diierent sizes and values of coins comprising a ten-cent piece or so-ca-lled dime, a iivecent piece or so-called nickel, and Ia twenty-tive-cent piece or so-called quarter, from each other and from spurious coins or slugs of the same sizes or diameters. This device will separate legitimate coins of the three sizes or values from various spurious coins of the same sizes made of other metals or alloys, such for example as copper, brass, lead, aluminum and so forth, or even paper discs, the spurious coins being generally called slugs. The coin selector is illustrated by itself, but it will be understood it may be mounted in any suitable location in any machine or device to be controlled, such, for example, as a dispensing mechanism Ifor various arti-y cles, which machine is not shown, telephones or other coin-controlled devices, the good coins of diiferent sizes and values being conducted or directed by any suit-able means (not shown) to the respective mechanisms to be controlled or released, and the bad or spurious coins or slugs being kept from the controlled mechanism or devices and directed to any suitable container or ejecting means (also not shown).

The device illustrated comprises an upright main or intermediate plate 1 having three openings 2, 3 and 4 therethrough, which openings are of diiferent sizes, as shown in FIGS. 1 and 5, to accommodate the three coins of different diameters, ten-cent, tive-cent and twenty-livecent pieces, and these three openings are arranged in succession, as shown in FIGS. 'l and 5, from -a coin inlet opening 5 at the top and one edge of the machine. This opening 5 may be flared as shown to facilitate insertion of the coins and may be formed in a flat tubular member 5a embracing the top edges of plates 1 and 6. A front plate 6 is secured to the forward side of the main plate 1 and spaced therefrom to provide a passage trom the inlet opening S to the openings 2, 3 and 4. 'The for-ward plate 6 is spaced from the main plate 1 by suitable separating means 7a and 8a forming runways 7 and 8 for coins inserted in the opening 5, the separator 8a being an inclined bar forming a runway 8 for rolling coins in the passage between the plates 1 and 6, and at the lower edges of the openings 2, 3 and 4, which may be called coin selector openings. The runway 7 is the top edge of separator 7a between the plates 1 and 6. The runway 7 is above and forwardly of the runway y8 and located di-rectly under the inlet opening 5 and above this runway, and -spaced somewhat from its `discharge end is a light spring 9 located in the coin passage between the inlet opening 5 and the coin selector openings 2, 3 and 4. This light spring is an arcuately curved leaf spring having its concave side facing the inlet opening 5 and spa-ced a distance from the runway 7 so that all coins or slugs running off the inc-lined runway 7 toward the runway 8 will deflect this spring backwardly, as indicated by the dotted line position 9a. Light weight slugs, such as aluminum or aluminum alloy discs or paper discs, as indicated by the circles 10 of alternate dot-and-dash lines, will be deected `by this spring into a reject passage 11 formed on the front side of the plate 1 by an extension of the plate 6, which reject passage leads to a reject chute 12 formed with the plate 1 on the front side thereof by a flanged plate 13 which has its opposite edges bent inwardly forming spaced anges 14, which spaces this plate from the plate 1 to form the reject chute. This spring may be adjustably mounted on one side of the plate 1 by a small plate 9b having an elongated slot 9c with a securing screw 9d. This permits locating of the spring in the best position for most effective action.

Also located at the free or inner end of the runway 7 is a xed permanent magnet 15 which is so located that if the lspurious coins 10 contain magnetic material they will be deected to the left as viewed in FIG. l, as they pass over this magnet and therefore will also be deflected into the reject passage and chute 11 and 12. These will keep all the light weight slugs and slugs containing magnetic material out of the selector passages for the legitimate coins and the slugs or spurious coins of heavier materials or metals, and thus prevent clogging of the legitimate coin passageways by the light weight or magnetic slugs. The magnet 15 may be mounted in the passageway between the inlet opening 5 and the coin select openings 2, 3 and 4 by any suitable means. In the arrangement shown it is located in an opening 16 in the plate 6 and extends across the passageway between this plate and the plate 1, and is removably retained in this position by a small metal plate 17 secured by the screw 18.

The three openings 2, 3 and 4 in the plate 1 are shown in FIGS. 1 and 5, located in succession or one after the other at one side of the inclined runway 8. They are of a size to permit the passage of the three different sizes of legitimate coins, as shown by the dotted lines, `in FIGS. 1 and 5, a ten-cent piece or dime being indicated at 19 passing through the opening 2, a live-cent piece or nickel being indicated at 20 passing through the opening 3, and a tWenty-ve-cent piece or quarter 21 passing through the opening 4. It will be seen that the opening 2 is the smallest opening, the opening 3 of intermediate size, and opening 4 the largest, and they are arranged in a line or in succession, with the smallest opening 2 nearest the inlet opening 5. Therefore all coins rolling down the runway 8 go at least as far as the smallest opening 2. If the coin is a ten-cent piece or a slug of the same diameter as the ten-cent piece, it will pass through this opening 2, but if it is of a larger diameter it cannot pass through the opening 2 but must roll on to one of the succeeding openings 3 or 4. If it is the diameter of a live-cent piece or nickel it will pass through the opening 3, but if it is of the diameter of a twenty-ve-cent piece it cannot pass through either of the openings 2 or 3, but must pass on to the largest opening 4, which will permit `it to pass. Means is provided at the various openings to assist and direct the coins and slugs through the various openings 2, 3 and 4 Corresponding to the different diameters. In the construction shown, the plates 1 and 6 are tipped or inclined backwardly, as shown in FIGS. 2 and 3, so that the coins rolling down the runway 8 are inclined Xbackwardly, with their upper edges resting on the surface of the plate 1. Thus as they reach the various openings 2, 3 and 4 they will automatically tip into the openings of the proper size with their forward edges engaging the forward edges 2a, 3a and 4a of the respective openings, which, with the rearward inclination of the coins will act to deect them through the respective openings. The first opening 2 is of a size too small to permit passage of the larger coins, ve-cent and twenty-five-cent pieces, and the second opening 3 is too small to permit passage of the larger twenty-ve-cent pieces. Therefore the veand twenty-tive-cent pieces rolling down the runway 8 must pass the opening 2 and the twenty-tive-cent pieces must pass the opening 3. The two runways 7 and 8 are inclined at the proper angle or pitch so that the coins rolling down the runway 8 will have the proper speed to pass into and through the proper openings and will not have suflicient speed to pass them.

Means is provided on the opposite side of the main plate 1 forming a passage from each opening 2, 3 and 4 for the coins passing through these openings to lead them to outlet openings for legitimate coins and reject openings for spurious coins, each passage leading to both a legitimate and a reject passage outlet. In each of these passages there is provided means for permitting the coins to roll through the passage and also means for separating legitimate rolling coins from the spu rious coins or slugs of the same diameters and leading the good coins to the proper outlet opening and the slugs to the reject opening. These respective passages are shown in FIGS. 6, 7 and 9, the passage in FIG. 6 being for coins and slugs of the diameter of a ten-cent piece; the passage of FIG. 7 being for passage of coins and slugs of the diameter of a five-cent piece, and the passage of FIG. 9 being for coins and slugs of the diameter of a twenty-ve-cent piece.

Referring tirst to FIG. 6, the ten-cent piece 19 passing through the opening 2 drops into a passage 22 formed at the rear side of the plate 1 by a third plate 23. Separating members 24 and 25 are located between the plates 1 and 23 to provide for the passage. As a coin the diameter of a ten-cent piece passes through the opening 2 it drops into the passage 22 onto an inclined upper edge 26 of the spacing element 24 which provides a runway for the coin. Legitimate ten'cent pieces are indicated by the full line circles 19, while slugs or spurious coins of the same diameter are indicated by dotand-dash circles 28. As these coins roll down the runway 26 the drop through a continuation 22a of the passage 22 onto an inclined runway 29 on the top edge of the spacing element 25, during which the direction of movement of the rolling coins is reversed and their speed retarded in preparation for passing the poles 30 of a permanent magnet located in openings in the plates `1 and 23 on opposite sides of this passage and as shown in FIG. 6, just oft the free end of the runway 29. If the coin is a legitimate ten-cent piece, as it has a high content of silver it is highly conductive for the magnetic field between the two poles of the magnets, generating sucient induced electric current in the coin so that its motion is retarded and the coin will drop substantially straight downward from the end of the runway 29, as indicated by the full line circles in FIG. 6, and will pass out the legitimate exit opening 31. Spurious coins or slugs, having less electrical conductivity, will not be retarded suciently to pass out the opening 31, but as indicated by the broken dot-and-dash circles, will pass farther to the right and out the reject opening 32. There are also provided in the passage between the plates 1 and 23 and above the openings 31 and 32 adjustable deectors 33 and 34 to assist in keeping the legitimate coins or slugs separated as they drop through the passage and to direct them to respective outlet openings 31 and 32. These deectors are formed as lateral extensions of plates 35 and 36 adjustably secured on the outside of the plate v1 by suitable screws 37 in elongated slots 38 with the lateral extension extending through openings 39 and `40 in the plate, whereby the deflectors 33 and 34 may be adjusted to the proper positions for effectively detlecting the coins and slugs to their respective outlets 31 and 32. There may also be a detlector and separator 29 between openings 31 and 32 provided with inclined sides to help dire'ct the coins and slugs to the openings.

The passage 41 for the five-cent pieces 20 and slugs of the same diameter is formed between the plate 23 and a fourth plate 42, there being spacing elements 43 and 44 between these plates to separate them to provide the passage and also to provide rolling and guide means for the coins passing through the passage. As the five-cent piece or slug of the diameter of a five-cent piece passes through the opening 3 a lateral ange 45 in alignment with the bottom edge of the opening 3 directs it into the passage 411, where it drops onto an inclined runway 46 on the top edge of the separator 43, along which it runs to a downwardly extending portion 41a of the passage onto the inclined top edge 47 of the separator 44, which provides a further extension 41b for the passage between this edge 47 and the lower edge 43a of the separator 43. Located on the opposite sides of this passage at the exit from the portion l4lb are the poles `48 of permanent magnets 49 located in openings in the plates 23 and 42 on opposite sides of the passage. As the five-cent pieces are made of an alloy which is a poorer conductor of electricity than the alloys of the spurious coin, these iive-cent pieces 20 indicated by full line circles in FIG. 7 will pass freely between the poles of the magnet to a legitimate outlet opening 51, while spurious coins 52 of better conductivity, indicated by the dot-and-dash line circles, will be retarded and directed to the reject opening 53. To help separate the legitimate and the spurious coins, an adjustable detlector 54 as well as a triangular shaped deector 55, may be provided in the passage between the outlets 51 and 53 and sufficiently above them to direct the spurious coins to their respective outlets.

The passage 56 for the twenty-iive-cent pieces 21 and spurious coins or" the same diameter leading from the opening 4 is provided by a fth and back plate 57, which is separated from the plate 42 to provide this passage by separating elements 58 and 59 and also by laterally extending iianges 60 and 61, which extend across the passage at the Outer edges thereof. As the twenty-iive-cent pieces or spurious coins pass through the opening 4 they are directed by a laterally inclined flange 62 into the passage 56, this flange being located in alignment with the bottom edge of the opening 4 and passing over the edges of the plates 23 and '42. As these coins pass into the passagetS they drop onto the upper edge 63 of the spacing element 58 down which they roll to a vertical connecting portion 56a of the passage onto the inclined top edge 64 of the spacer 59. This spacer forms a reverse extension 46b of the passage 56 between this edge 64 and the lower edge 58a of the spacing element 58. At the outlet of this extension of the passage and on opposite sides of the passage are the poles 65 of permanent magnets 49 and 49a located in holes in the plates 57 and 42. As the coins leave the extension 56b of the passage at the free end of the inclined runway 64 they pass between the two poles 65, and as the twenty-tive-cent pieces 21, indicated by the full line circles, are made of an alloy containing a large amount of silver they have sufficient electrical conductivity so that as they pass through the magnetic eld between the poles suicient current is induced in these coins so that they are retarded and drop through the legitimate coin outlet 67, while spurious coins or slugs 68, indicated by the dot-and-dash line circles, of the same diameter of alloys or other metals of less conductivity, as they pass between the poles are not retarded sufciently to pass through the outlet 67 but pass to and through the reject outlet 69. To further assist in separating the good from the bad coins an adjustable deector 70 may be provided in the passage 56 above and between the openings 67 and 69, together with an inclined spacing element 71 below this deflector. This deector may be a laterally extending end of the plate 72, adjustably secured on the back of the plate 67 by the screw 73, with the detlecting end 74) passing through an opening 74 in the plate. This permits setting of the deiiector 70 at the proper location for proper directing of .the legitimate and spurious coins to the outlet openings 67 and 69.

The magnets 49 and 49a providing the various pole pieces 30, 48 and 65 may be mounted on the outsides of the plates 1 and V57, as shown in FIG. 3, and'held there by any suitable means, such, for example, as sheet metal casings 75 secured to the plates by the end extensions 76 and screws 77. The various plates 16, 23, 42 and 57 may be secured together by any suitable means, such, for example, as the screws or bolts 78 and 79, which may also be used to secure the various separating elements between the plates in` proper positions to provide the various passageways for the rolling coins.

It will be seen from the above that this device provides a simple and eifective means for separating a plurality of legitimate coins of different values and diameters, such as the ten-cent, tive-cent and twenty-tive-cent pieces from each other and also from spurious coins or slugs of similar diameters, and will direct the legitimate coins to separate legi 'mate outlets from which they may be conducted by suitable means to various mechanisms which may be controlled by the separate coins, and that also the spurious coins or slugs, whether of heavy or light metal or light, nonmetallic material, as well as heavier slugs of base metals, or any magnetic material, are readily identied and directed to proper reject outlets so that they may be kept from the mechanisms to be controlled by the legitimate coins. Although the device illustrated has been shown as providing means for separating coins of three values and diameters, it will be understood the same mechanism and arrangement may be provided for separating the coins and slugs of two diameters and values. Thus it may be used for separating tenand ve-cent pieces, for tenand twenty-tive-cent pieces, or the veand twentytive-cent pieces, if it is desired to use the device with mechanisms responsive to the controls of these coinsonly,
