4 Claims. (Cl..194--100) This invention relates to a coin selector for separating good coins from spurious or bad coins, or so-called slugs, and has for an object to provide a simple and effective device which will effectively separate good coins from all. kinds ofspuriousor bad coins, such as coins of baser metals, such, for example, as lead or brass, or coins containing iron, or even discs of paper or like material, and direct them into different chutes for either directing the good coins to a mechanism, such as a dispensing device to be controlled, and to direct the so-called slugs tcli1 a separate container or to eject them from the mac me.

Another object is to provide a device of this character in' which there is no reliance placed on bouncing of the coins to effect separation, but they all roll smoothly through the device.

A further object is to provide a device of this character which is very simple in 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 with which it is applied.

With the foregoing and other objects 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 changes and modifications within the scope of the invention.

Referring first to the form of the device in Figs. 1 to 6, this device is shown as. desiged. for separating the five-cent coin, or so-called nickel, from various spurious coins made of other metals or alloys, as for example, copper, brass, lead, aluminum, and so forth, or even paper discs, these latter coins being generally called slugs. The coin selector for use in such an arrangement is shown, and it is to be understood it may be mounted in any suitable location in a machine to be controlled, such, for example, as a dispensing machine for various articles, which machine is not shown, the good coins being conducted or directed by any suitable means (not shown) to the mechanism to be controlled or released, and the bad coins or slugs being kept from the dispensing machine and directed to any suitable container (also not shown).

The device illustrated comprises a forward plate or main plate 10 and a rear plate 11 mounted on the rear side of the plate 10 and separated from it by separating members 12 and 13 forming coin chutes or passage-ways 14 and 15 between the plates. The upper edge of the plate 10 is provided with an car 16 rolled into a hinge loop for a hinge pin 17 on which is mounted by similar hinge loops 18 a swinging plate or gate 19, which is adapted to have limited outward movement at its lower edge away from the plate 10, and this edge is bent inwardly to form an inclined flange 20 forming the bot tom of a coin runway. This plate has an upward extension 21 at the forward or right hand edge of plate 10, which extension is inclined backwardly and upwardly from an upward extension 22 of the plate 10, and on the rear side of this plate is a lever 23 pivoted to the plate at 24 and connected by a lug 26 to a spring which at its other end is connected to a bracket arm 27 mounted on the upper edge of extension 21. This spring normally tends to shift the lever 23 upwardly and hold it in the position of Figs. 1, 2 and 6 The extensions 21 and 22 are spaced so as to provile a coin entrance chute 28, and mounted on the extension 22 and extend ing forwardly from this plate is a pin 29, and a similar pin is located below it on the lever 23. When the lever is in its normal upper position the pins 29 and 30 are spaced a distance less than the diameter of the coin for which the device is designed, in this case the nickel, or five-cent piece, indicated in dotted lines at 31, Fig. 1'. Also these pins 29 and 30 are located behind a coin entrance slot 32 in a wall 33 of the casing or housing of the machine in which the device is mounted and to be used, this slot being the coin slot through which the customer will insert the coin. Therefore, the entrance to the chute 28 which is back of the pins 29 and 30 is in alignment with this slot 32 and any coin inserted in the slot 32 and forced between the pins 29 and 30 will drop down this chute or coin passage 28, as indicated by the dotted coin disc 31a, and will land on the bottom wall or flange 20 of the hinge plate 19. This wall 20 is inclined downwardly and rearwardly to the left as viewed in Fig. l, and terminates at the point 20a at one end of the wall 34 bent forwardly or outwardly from the wall 10, as shown in Fig. 5, and forming the entrance to the coin passage 14, the rear upright edge wall of the plate 19 being bent inwardly toward the plate 10 forming a stop wall 35, so that a coin rolling down the wall 20 will be stopped by the wall 35 and be deflected laterally by the wall 34 into the coin passageway 14, as indicated by the dotted circle 31b of Fig. 1. This coin will then pass down the top of the separator 13, which is inclined downwardly toward the right as viewed in Fig. 1, through the passage 14 and drop into the passage 15, as indicated at 31c, and will run along the top 12a of the :eparating plate 12, this being inclined downwardly to- Ward the left as viewed in Fig. 1, and will pass between the poles 36 of a strong permanent horseshoe magnet 37. The poles 36 of this magnet are located on the opposite sides of the passage between the plates 10 and 11, and as shown in Figs. 1 and 2 are located in openings 38 in these plates, but with their forward faces spaced backwardly slightly from the inner faces of the plates, so a coin passing through the space between the plates will not come in direct contact with these poles. These poles, as shown in Fig. 1, are located at the outlet of the passage 15 just beyond the upright inner edge 12b of the separating plate 12, so that any coin passing from the passage 15 will pass between the poles 36 of the magnet, and through the strong magnetic field between these poles. If it is a nickel five-cent piece, due to the high electrical resistance of the metal of which this coin is made, very little current will be generated or induced in the coin as it passes between these pole pieces, and therefore it would be only slightly retarded and its momentum will carry it beyond these pole pieces, as indicated by the dotted circle 31d, and it will pass out the outlet slot 39 at the left of a dividing or stop wall 40 between the lower edges of the plates and 11. If the material of the coin, instead of being the nickel alloy, is of brass, copper, or some other metal or alloy having greater electrical conductivity, as it passes between the poles 36 sufficient electrical currents will be induced in it to retard the movement of this spurious coin or slug, and instead of passing through and out the slot 39 it will be retarded and drop substantially straight downwardly from the magnet pole pieces, as indicated by the dash and double dot circle 41, and will drop out the slot 42 at the right of the division wall 40. It will, of course, be understood that suitable chutes or guideways (not shown) will be provided to direct these coins to diiferent locations or containers, the good coins passing from the slot 39 to the machine or mechanism to be controlled, while the bad coins or slugs from the slot 42 are thrown out or directed to a suitable container, thesepassages or cllliutes not being shown in the drawings, to simplify t em.

It will be understood from the above that should a slug containing iron or other magnetic material be inserted through the slot 32 and take the path indicated to the magnetic poles 36, it would be caught and held by these poles and would clog the machine unless some means were provided to eject it from its position between the magnetic poles. However, in this device, to obviate clogging of the device, means is provided for arresting such magnetic coins and ejecting them before they reach the magnetic poles 36. This comprises a small permanent magnet 43 secured by any suitable means, such as the clamp 44, on the outer side of the plate 19 immediately above the lower inturned wall 20 of this plate, so that as the coin rolls down this wall 20, if it contains iron or similar magnetic material it will be arrested and held by this magnet as indicated by the dot-and-dash circle 45 in Fig. l and by the coin shown in full lines in Fig. 4. Between the free ends or poles of this magnet the plate 19 is provided with a slot 46 into which projects the top horizontal wall 47 of a bracket 48 mounted at 49 on the wall of a plate 50 secured to the outer wall of the plate 10 by any suitable means, such as the lugs 51, the edges of this plate being bent inwardly to form flanges 52 and engaging the face of the plate 10 to space the plate 50 from the plate 10 r and form a discharge chute 53 between the plate 50 and the plate 10, and having a discharge slot 54 at the lower edge of this plate. The upper end of this chute or passage 53 is lengthened and lies immediately below the horizontal wall 20 of the hinge plate 19. The lower edge of this plate 19 may swing outwardly away from the plate 10 to carry the wall 20 away from its position above the entrance to the chute 53, as indicated in Fig. 4, the plate 19 being normally held in its inner position or the dotted line position of Fig. 4, by a spring plate 55. The inner edge of the wall or finger 47 is spaced from the wall 10 a sufficient distance to permit the coin to pass between them, but if a coin should be caught and held by the magnet 43 between these elements, as shown at 45 in Fig. 4, when the plate 19 is swung outwardly to the full line position of this figure the wall or finger 47 will prevent the coin from moving with it, and as the magnet is carried with the plate 19 the member 47 will separate the coin from the magnet, and as soon as it is freed by the wall 20 it will drop downwardly into the chute 53 and pass out the discharge slot 54 from which it may be conducted to a separate container or any location desired. This lower portion of the plate 19 is swung outwardly to free the coin held by the magnet 43 by insertion of a coin in the entrance slot 32, as indicated at 31, Fig. 1. Thus, when such a coin is inserted it will have to pass between the pins 29 and 30. However, as these pins are normally spaced less than the diameter of the coin, the lower pin which is mounted on the lever 23 will force this lever downwardly as shown in Fig. 4. This action will tension the spring 25 and by pulling downwardly on the arm 27 will swing the lower end of the plate 19 outwardly to the full line position of Fig. 4 and free the coin 45.

Also provided at one side of the passage 28 above the wall 20 is a very light, flat spring 56. This is of sufiicient tension to stop and hold a very light disc, such, for example, as a paper disc, and prevent its passing down through passages 14 and 15, and although it is of sufficient strength to arrest such a light disc rolling down the wall 20, it is not sufiicient to hold the weight of the disc after this wall 20 has been swung outwardly, as indicated in Fig. 4, so that when this is swung out by the insertion of the next coin in the slot 32, the disc held by the spring 56 will be released and drop down the chute 53 and will be discharged the same as would be a magnetic coin.

Briefly, then, the operation is: When a coin is inserted in the slot 32 the operator must force it inwardly between the pins 29 and 30. This action will swing the lower portion of the plate or gate 19 outwardly and shift its lower wall 20 outwardly from its position over the chute 53. However, before the coin drops down wardly in passage 28 to the position of this wall 20, the plate 19 will again have been swung back to its normal position by the spring 55, as soon as the pin 30 is released by the coin. If it is a legitimate coin, in this case, the nickel five-cent piece, it will roll down the wall 20 and be deflected by the wall 34 into the passage 14, as indicated by the dotted circle 31b. It will then roll downwardly to the right on the inclined top edge of the separating plate 13 and drop off the edge of this plate to the position 31c onto the top edge 12a of the separating plate 12. It will then pass in the opposite direction along this edge 12a through the passage 15 and between the poles 36 of the magnet 37, and being a legitimate nickel coin, there will be very little electric current generated in it as it passes through the magnetic field under its momentum, and it will not be retarded sufiiciently to prevent its passing beyond the dividing stop or wall 40, as indicated by the dotted circle 31d, and out the slot 39. Should, however, the coin be a magnetic coin, or that is, one containing iron, it will operate the wall or gate 19, the same as the other coin, but in rolling down the wall 20 in front of the magnet 43 it will be caught and held by this magnet, as indicated by the dot-dash circle 45 in Fig. 1. This will prevent its passing down through to the poles 36 of the magnet 37 and being held there to clog the machine. When the next coin is inserted through the slot 32, it will force the pin 30 downwardly to swing the plate 19 outwardly. This will free the coin 45 held by the magnet 43 because it will be prevented by the wall 47 from moving outwardly with the wall 19 and the magnet 43, and this coin 45 will drop down the chute 53 as shown at 45a and be discharged through the slot 54. The plate 19 will, however, be swung backwardly to its normal position before the last inserted coin reaches the wall 20, and therefore this coin will roll down the wall 20 toward the passage 14. If this coin is a legitimate coin it will pass on through as previously described. If it is another magnetic coin or slug it will be caught and held by the magnet 43, the same as the preceding slug. If it is a light paper disc it will be caught by the spring 56 and held in the same position as indicated by the circle 45 until another coin or slug is inserted through the slot 32, when it will be released and discharged through the chute 53, the same as was the magnetic slug.

In the modification of Figs. 7 to 13, the principle of operation is exactly the same, but the device has been slightly modified to separate the silver ten-cent piece or dime from other coins or slugs. In this case, as the silver of the legitimate ten-cent piece is a high conductor of electricity, and is a better conductor than the spurious coins made of such material as copper, brass and so forth, greater currents will be induced in the good coin or the ten-cent silver piece as it passes through the magnetic field between the poles of the strong magnet, and so will be retarded and drop straight downwardly, while the spurious coins or slugs having less current generated in them will be less retarded and will pass on through be tween the poles of the magnet and so can be readily separated from the silver pieces. The device shown comprises the main plate 57 corresponding to the plate 10 of the first form and the rear plate 58 separated from it corresponding to the plate 11 of the first form, the separating plates being indicated at 59 and 60, and therefore form coin chutes or passages 61 and 62. The top edges of the plates are inclined, as indicated in Fig. 7, so that the COlIlS roll down them and pass through as indicated by the arrows. On the forward side of the plate 57 is another plate63 with its edgesbentbackwardly to. form flanges 64 to (engage the plate 57,.tl1usspacing the plate 63 from the; plate 57 to form a dis'harge. chute 65 leading to a d scharge. slot 66. Thiscorresponds to the discharge chute 53'of the firstzform, and its upper end 65a is located beneath the;lower edge of. a swinging plate or gate 67 corresponding'to the plate 19 of the first form. This plate 18 hinged'to the plate 57 at 68,: and at its lower edge is provided'withan inturned flange or wall 69 corresponding to the wall 20 of the first. form, extending inwardly toward the plate 57 and. normally positioned above the entrance to the chute 65, as indicated .in full lines in Fig. 1.0and: dottedlines in Fig. 11, and the plate 58 is normally held: in this position by the spring 70 secured to the back plate 58. at 71. This plate 67 carries a permanent magnet 72 mounted .on any suitable means, as the clamp 73, this magnet corresponding to the magnet 43, of the first form, andis located a short distance above the wall 69. The plate 67 is provided with an elongated opening 74yadjacent this magnet in which is normally located the lower wall 75 of a. sheet metal bracket 76 secured to the rear wall 58 at 71. This is a stationary wall or finger which clears the coin or slug held by the magnet 72 to separate it from the magnet when the plate 67 is swung outwardly-and corresponds to the released finger or wall 47 of the first form. Opposite this wall and on the wall 57 is mounted a very light spring 77 corresponding to spring 56: of the first form to stop and retain veryv light Weight discs, such, for example, as paper discs and the like. The main and strong magnet is indicated, at- 78 and has its poles 79 located in openings in the plates 57 and 58 just beyond the lower end of the inclined wall 69 of the passage 62, as indicated in Fig. 7, the passage between the end. of this separator 60 and the opposite end wall 57a being separated at its lower edge by a dividing wall. 80 dividing: this passage into two discharge slots 81: and 82.v

Plate 67 is provided with an upward extension 83 on which there is a bracket arm 84 through which passes a rod 85 connected toa lug 86 on a lever 87 pivoted to the plates 57 and 58 at 8,8, and aspring 89 on this rod tends to force the lever 87 upwardly. This corresponds to the lever 23 and associated parts of the first form. Carried; by the plate 57 is a pin 99 infront of the coin entrance passage 91 between. the plates 57 and 7 an belowthispin is another pin 92 carried by the lever 87. Thesepins correspond to the pins 29 and 30 of the first form and have the same. function. They are placed behind the coin entrance slot 93 in the housing or casing 94of the machine in. which the device 18 applied and. are spaced a less distance than the diameter of theco ins, a good coin, such, as a ten-centsilver piece being indicated by the dotted circle 95, partially inserted through this slot to engage the pins 90 and 92.

The principle of operation is the same as the first form,

but as indicated, as this device is to separate a coin of difierent size and material, that is, a silver ten-cent piece, from spurious coins or so-called slugs, it is arrangedsomewhat diflterently, as described. Briefly, the operation is: When a good coin or silver ten-cent piece indicated by the dotted circle 95 is inserted, it will force the pin 92 downward, which will force the lever 87 downwardly and compress the spring 89, this spring acting through the arm 84 will swing the lower edge of the plate or gate 67 outwardly, carrying with it the lower wall 69. However, immediately the coin 95 passes the pin 92, the plate is released and the wall 69 is swung backwardly to its normal position over the chute 65 while a coin as indicated at 95a is passing down the passage 91. This coin rolls down the wall 69 as it is inclined downwardly toward the rear, and this wall terminates at 69a in front of an opening 57a in the plate 57, the lower edge of which opening is bent outwardly under the plate 67, as indicated at 57b. As the coin runs off the end of the wall 69 t is deflected by this wall 57b through the opening 57a into the passageway 61 and drops onto the top edge 59 of the separator, as indicated by the dotted circle 95b, Fig. 7. The coin then rolls down this inclined wall 59 and drops off its inner edge onto the inclined wall 69, as indicated at 950. It then rolls in the opposite direction down the inclined wall 60, as indicated by the arrow, and passes through the strong magnetic field between the poles 79 of the magnet 78. If it is a legitimate coin, in this case the silver ten-cent piece, suflicient electric current will be induced in the coin to cause it to be retarded by the magnetic field and itwill drop downwardly as indicated by the dotted circled and will pass out the discharge slot 81 from which it may be carried by any suitable funnel or passage to any point desired, such as the release mechanism of the machine to be controlled. However, if it is a copper or other so-called slug, of greater electrical resistance. than the silver ten-cent piece, insuflicient current will be induced in it as it passes through the magnetic field between the magnet poles 79, and instead of being retarded so as to pass out the slot 81, its momentum will carry it beyond the dividing wall 80, as indicated by the dash-and-double-dot circle 96, and will pass out. the discharge slot 82, where it may be led or conducted to a suitable container. If the coin happens to be a magnetic slug or one containing iron, as it rolls down the wall 69 it will be stopped and retained by the magnet 72, as indicated by the dot-and-dash circle 97. Then when the next coin is inserted pin 92 will be forced downwardly, swinging these walls 67 and 69 outwardly to the full line position of Fig. 7, as previously described. This will carry with it the magnet 72, but on account of the stationary wall 75, the coin cannot follow the magnet but will be released from it, and as soon as the wall 69 passes from under the coin it will drop into the chute 65 and will be discharged through the discharge slot 66, as indicated by dot-and-dash circle 97a. If the slug happens to be a=very light disc, such as a paper disc, it will be caught and retained by thespring 77, as it rolls down the wall 69. On the insertion of a succeeding coin, the wall 69 will be swung outwardly, releasing this disc so that it will drop, into the passage 65 and be discharged at 66 the same as a magnetic slug. It will thus be seen that this device operates the same way as the first form.

In each form an oblong coin or slug will not roll down the wall 20 or 69, but will be retained by this wall and held so that it will be released on insertion of the next coin by outward movement of the wall 20 or 69, and will be discharged through the passage 53 or. 65, the same as the magnetic coin. Light spring 56 or 77 also helps to. hold such an oblong coin against rolling. If the slug is a sufliciently heavy disc so as not 'to be retained by the light spring, it would be thrown out at the lower end of the device, the same as other slugs. It will be seen from the arrangement of coin passages that there are no. anvils or bouncing action of the coins used for separating. them, but they all roll smoothly through the device. The inclined. bottom walls of the various runways are inclined at the proper angle to give the proper movement and momentum of the coin, although they are not confined to any specific angle but are designed according to the lengths of. the paths involved. ,They are usually inclined at an angle of about 30, or somewhat less. The very light springs 56 and 77, while providing sufficient pressure to hold a very light disc, such as a paper disc, will not prevent the heavier or metal coins from rolling freely through. By arranging the runways and various coin passages as described and shown, the size of the unit is greatly reduced and the construction is also greatly simplified. It can be assembled as a unit separate from the machine in which it is used and then mounted as a unit in this machine.
