9 Claims.

This invention relates to coin operated devices particularly of the type arranged to receive coins of diierent denominations and has for an object the provision of improved means for discriminating between slugs and genuine coins in accordance with their electrical conductivity.

It has been previously proposed in slug rejection to employ a downwardly inclined coin runway terminating in a gap defined in part by a wall separating a reject chute from a collect chute and to provide a powerful magnet adjacent the runway of sufficient strength to retard the speeds of a genuine coin and a slug oi diierent electrical conductivities by such relative amounts that the slug will be directed into the reject chute and the genuine coin into the acceptance chute. In applying this principle of slug rejection to separate runways individual to United States live-cent, ten-cent and twenty-nve-cent coins it is necessary to provide special arrangements for each runway not only due to the different relative weights and sizes of the coins but also because the usual five-cent slug if of a higher electrical conductivity than the standard live-cent coin, while the usual slug encountered in runways for silver coins has an electrical conductivity lower than the corresponding silver coin. Hence, in arranging the entrances to the accept and reject chutes consideration needs to be given to the fact that a five-cent coin will have a greater exit velocity than the undesired five-cent slug, while for the ten-cent and twenty-iive-cent runways are genuine coin will have a lower exit velocity than the type of slug usually encountered.

In accordance with this invention a coin chute for receiving coins of different denominations is provided with a common coin entrance comprising a downwardly inclined coin runway having adjacent thereto a strong magnet for retarding the speed of coins or slugs in accordance with their electrical conductivities. Adjacent the lower end of the downwardly inclined runway is a movable chute section which in one position provides a properly arranged acceptance chute and reject chute for coins and slugs of one denomination discharged from the stationary runway, while in a second position provides a properly arranged acceptance chute and reject chute for coins and 'slugs of a different denomination. Suitable means are also provided for adjusting the movable chute section into the proper position for the denomination of each coin deposited. For eX- ample, the coin entrance slot may comprise a movable wall which in order that a coin may be fully inserted in the slot must be moved a distance determined by the diameter of the inserted coin. The movable wall is suitably coupled to the movable coin chute section in such a manner that when a vecent coin is deposited the movable chute section will occupy the appropriate position for discriminating between standard vecent coins and slugs, while when occupying another position will discriminate between coins and slugs of a diiierent denomination such as a United States ten-cent coin or twenty-ve-cent coin.

Fig. 1 is a View of a telephone coin collector of the general type disclosed in the O. F. Forsberg United States Patent 1,043,219 modified to include the coin chute assembly of this invention within the upper housing I5. A ve-cent, ten-cent or twenty-ve-cent coin may be inserted in slot Il in the top wall of housing |53, whereby the coin will enter the coin chute assembly i8 to actuate a suitable sound signal before being discharged into a coin hopper I9 where the coins are held in suspense for subsequent collection or refund under the control of a suitable coin relay 2t.

The present invention is primarily concerned with the rejection of live-cent, ten-cent and twenty-nve-cent size slugs having an electrical conductivity substantially diierent from the standard coins and the coin chute assembly I8 is provided with means for rejecting slugs of the type described.

The upper portion of the chute assembly I8 comprises two spaced plates, a front plate 23 and a rear plate 24, having near their upper rightliand corner a coin entrance slot 25 defined by a stationary roller 26 and a movable roller 21. Slot 25 registers with slot |1 in the upper housing and is adapted to receive either a five-cent, ten-cent or twenty-ve-cent coin. As shown in Figs. 10, 11 and 12, any coin passing between rollers 26, 21 drops vertically onto a downwardly inclined ledge 28 down which the coin rolls to be projected between the poles of two permanent magnets 28, 30 in order that the projected speed of each coin or slug may be retarded an amount determined by its electrical conductivity. The deposited coin then falls between partitions in a movable coin chute section 3| where the different trajectories of a genuine coin and a corresponding slug enable the slug to be rejected and the genuine coin to pass into the acceptance channel.

The movable coin chute section 3| as shown in Fig. 6 comprises four spaced plates 34, 35, 36 and 31 slidably mounted on two horizontal pins 38, 30 which in turn are suitably supported by brackets 48, 4|. When a ten-cent coin is deposited movable section 3| should be moved to a position shown in Figs. 10 or 13, whereby the ten-cent coin or slug after traversing the magnetic eld of magnets 20 and 30 falls between walls 38, 35, the space between these walls being divided by a partition 44 into an `acceptance channel 45 and a rejection channel 46. When a ve-cent coin is deposited movable section 3| should be moved to the position of Fig. 11 or 14 whereby a five-cent coin or slug after-traversing the magnetic field of magnets 29 and 30 falls between walls 35 and 36, the space between these walls being divided by a partition 41 into a reject channel 48 and a collect channel 49. When a twenty-five-cent coin is deposited, movable section 3| should be moved to occupy the position of Fig. 12 or 15, whereby a twenty-fivecent coin or slug after traversing the magnetic field falls between walls 36 and 31, the space between these walls being divided by a partition 50 into an acceptance channel 5| and a reject channel 52.

Below the movable section 3| the coin chute assembly comprises three spaced plates, 53, 54 and 55. Plates 53 and 54 are aligned with upper stationary plates 23, 24, as shown in Figs. 13 to l5. The space between plates 53 and 54, as shown in Figs. 10 and 11, comprises a common channel for genuine five-cent coins and ten-cent coins. When movable section 3| occupies the position of Fig. 10 or 13, a genuine ten-cent coin drops through acceptance channel 45 to strike the upper edge of bell 55 and then after rolling down ledge 51 and having its direction reversed by guide wall 58 strikes the lower edge of bell 55 to be discharged through exit opening 59 into coin hopper I9. A genuine ve-cent coin when movable section 3| lies in the position of Fig. 1l or 14, drops through acceptance channel 49 to follow guide wall 58 between plates 53, 54 to strike the lower edge of bell 56 for discharge into coin hopper i9 through exit opening 59. A genuine twenty-iive-cent coin when section 3| is in its position of Fig. 12 or 15 drops into acceptance channel and by means of deector vane 66 is directed into an acceptance channel lying between plates 54 and 55 deiined by guide walls 60,

6|, 62 and 83 (Fig. 12) to strike gong 64 before being discharged through exit opening into coin hopper I9.

The manner in which the slugs are rejected will now be described. Assuming movable section 3| is in its position of Fig. 10 or 13, the portion of the space between plates 53 and 54 directly beneath reject chute 46 is closed to the entrance of a slug because of the presence of sloping ledge 10, the upper end of which is substantially a continuation of partition 44 of Fig. 10, while end wall 1| between plates 53, 54 is a substantial continuation of end wall 12 in movable sectiqn 3|. Plates 34 and 35 are cut away in the region above ledge 10 to provide a reject opening 13 through which a ten-cent slug will be rejected as shown for the ten-cent slug 14 in Fig. 13. Similarly if We assume movable section 3| to occupy the position of Fig. l1 or 14 with movable plates 35, 36 aligned with lower plates 53, 54, a ve-cent slug entering reject channel 48 will be guided by end wall 16 to strike ledge 10 for rejection through reject opening 13, as shown for the five-cent slug 11 in Fig. 14. Similarly, if movable wall 36 is aligned with lower stationary wall 53, a twenty-ve-cent slug on entering reject chute 52 will be guided by sloping end wall 18 and dei'lecting vane 19 into reject opening 13 for rejection, as shown for the twenty-five-cent slug in Fig. 15.

Next will be described the manner in which movable section 3| is set in a position determined by the diameter of the deposited coin. The coin insertion slot 25 has a length between stationary roller 26 and shiftable roller 21 which is smaller than the diameter of the smallest coin to be deposited, whereby roller 21 for coin insertion will be moved laterally a distance determined by the diameter of each deposited coin. Roller 21 is rotatively mounted on a bar 84 which is slidably mounted on stationary plate 24 by means of two stationary pins 85, 86 working in slots 81, 88 in bar 84. Bar 84 is biased to a normal position dened by the engagement of roller 21 against ledges 90, 9| of the coin slot 25 (Fig. 5) whereby the normal distance between rollers 26 and 21 is less than the diameter of a tencent coin, A bracket 92 serves as the pivoting support for a vertical rotatable pin 93 to which is fixed a cam carrying member 94. The upper arm of member 94 carries a pin 96 to which is fastened one end of a biasing spring 89, whereby arm 95 engages a cam 91 on slidable bar 84 to bias bar 84 to its above-described normal position with roller 21 engaging stops 90, 9|. It follows from this arrangement that when a vecent, ten-cent or twenty-ve-cent coin is deposited to cause the movement of bar 84 cam 91 acts against arm 95 to rotate vertical member 94 an angular amount proportional to the coin diameter.

Rotatable member 94 also carries two cams, 91 and 99, which control the slidable chute section 3|. Chute section 3| is biased to the position of Fig. 3 by means of two springs, |00 and l0 which tend to force spaced shoulders |20, I2| of movable section 3l against stationary portions |22, |23 of the chute assembly, as shown in Fig. 6. On that side opposite to springs |00 and l0|, chute section 3| carries a plate |02 bearing on its upper edge a series of three notches |03, |04 and |05. Mounted above plate |02 and supported by stationary bracket |05 is a hollow tube |01 containing a plunger |08 which by means of a spring |09 is biased to engage the upper edge of plate 10.2 vand enter any one of the thre'e notches .|03, |04 or |05. It may be noted, however, that when lplunger |08 is freed from notched plate |02 in a manner to be subsequently described, the action of springs and |0| on chute section 3| in urging shoulders |20, |2| against stops |22, |23 aligns chute section 3| in such a position that plunger |08 upon reengaging notched plate |02 will enter notch |03. The cam 98 is carriedby a bracket l|09 which is pivoted about a horizontal pin ||0 suitably supported by the cam carrier 94. Suitable stops hold bracket |09 in its position of Fig. 2 although bracket |09 is capable of counter-clockwise movement, as viewed in Fig. 5. Plunger |08 has a pin projecting through a slot in tube |01 for engagement by cam 98 whereby 'when cam carrier 94 is rotated counter-clockwise, as viewed in Fig. 5 the pin will ride up `the sloping surface of cam 98 to temporarily disengage plunger |08 from notched plate |02 until with the continuation of the counter-clockwise movement, the pin drops off the end ||9 of cam 98 and again permits plunger |08 to engage notched plate |02. On the return movement of carrier 94 in a clockwise direction, as viewed in Fig. 5, pin engages the under surface of cam 98, thereby lifting cam 98 upwardly about its pivot ||0 to permit cam 98 to be restored to its normal'position of Fig. 5.

After cam 98 has elevated plunger |08 in response tothe insertion of a certain coin, cam arm 99 yat the lower end of member 94 is adapted to engage wall 31 of movable chute section 3| to move section 3| against the action of springs |00 and |0| a distance proportional to the coin diameter so that when pin drops ofi the upper level `of cam 98 to permit plunger |08 to reengage notched plate |02, plunger |00 will be directed into that one of notches |03 to |05 which corresponds to the position to which plate |02 has been advanced by movement imparted thereto by cam arm 99. The maximum movement of cam carrier 94 in a clockwise direction, as viewed in Fig. 5, is limited by leaf spring ||4 which is adapted to be engaged by cam arm 99.

Before describing the manner in which movable section 3| is set in accordance with the vdiameter of a deposited coin, it is to be pointed out that the notches in the edge of plate |02 are so arranged that when plunger |08 lies in notch |03, the movable section 3| is held in a position which aligns the dime acceptance channel 45 and the dime reject channel 48 with the upper coin channel 28; when plunger |08 lies in notch |04, movable section 3| is held in a position which aligns the nickel acceptance channel 49 and the nickel reject channel 48 with the upper coin channel 28; and when plunger |08 lies in notch |05, section 3| is held in a position which aligns the twenty-rive-cent reject channel 52 and the twenty-ve-cent acceptance channel 5| with the stationary coin channel 28.

If now we assume that a dime is deposited in slot |1 by the employment of sufficient force to the coin to move roller 21 away from stationary roller 26 a distance equal to the coin diameter, it follows from the above description that the resulting lateral movement of bar 84 will cause shoulder 91 to engage arm 95 and rotate member 94 a distance sufficient to have pin i|| ride up cam 98 to temporarily release notched plate |02 from plunger |08 and permit movable section 3| to be restored from any previously advanced v,setting toits normal position of Fig. 13 under the action yof biasing springs |00, 0|. The maximum movement of .cam arm :99 when a dime is deposited vis su'fcient to cause only a .limited movement of sectionv 3| from its normal position, that is, insufficient to move plate |02 far enough to have notch |04 aligned with `plunger |08 so that when pin l'|| drops off the end ||9 of cam 98 the lower end of plunger |08 strikes plate |02 in notchv |03. When the dime has passed between rollers 26, 21, bar 84 and rotatable member 94 are restored to normal by means of biasing spring 89 and the resulting rotation of arm 99 away from engagement with section 3| permits springs |00, |0| to hold chute section 3| in the position defined by the engagement of plunger |98 with notch |03 whereby chute section 3| is maintained in a .position with the dime acceptance channel 45 and the dirne reject channel 46 properly aligned to receive the deposited dime or dime-size slug. If the deposited coin is a genuine ten-cent piece, the coin rolls dow-n ledge 28 and by means of permanent magnets 29, 30 its speed is retarted sufriciently to cause the coin to enter acceptance channel 45, strike the upper edge of bell 56 and then roll down channel 58 to strike the lower edge of bell 56 and pass out through the exit opening 59. In Fig. l0, the path of a genuine ten-cent coin is indicated by the broken lines |25-|20.

If a ten-cent size slug is deposited having a resistivity substantially greater than the resistivity of a silver coin such a slug upon entering the field of permanent magnets 29 and 30 will have its speed retarded less than the .silver coin whereby the slug will pass to the right of partition 44 to enter the 'reject channel 40 along the path indicated vby the broken line |21 and be rejected 'through opening`13 in the manner shown for 4slug 14 Tin Fig. 13.

If a standard five-cent coin is deposited in slot |1, bar 84 by means of the coin insertion will cause the rotation of cam carrier 94 on amount suicient to cause cam 98 to disengage plunger |08 from rthe edge of plate |02 and to cause cam arm 99 to move movable section 3| to a position aligning notch |04 with plunger |08, whereby when the pin rides off the `end ||9 of cam 98 the released plunger |08 will engage notched plate |02 in notch |04 whereby vthe nickel acceptance channel 49 vand the nickel reject channel 48 are aligned with the upper chute section 28. If the deposited coin is a standard ve-cent coin, the coin upon entering the field of magnets 29 and 30 will .have its speed retarded only to a slight degree whereby the coin passes t0 the right of partition 41 to enter acceptance channel 49 and pass downwardly through the channel defined by end wall 58 to strike the lower edge of bell 56 and pass out .of the chute through eXit opening 59. The

path of a genuine five-cent coin is indicated in.

Fig. 11 by the broken line |28. If a nickel-size slug is deposited having a resistivity substantially less than a vstandard five-cent coin, the slug upon entering the field of permanent magnets 29 and 30 will have its speed retarded considerablv more than a standard five-cent coin, whereby the slug will Apass to the left of partition 41 to enter reject channel 48 and be rejected through opening 13 in the manner shown for slug 11 in Fig. 14. The path lof a nickel-size slug is indicated in Fig. ll by thebroken line |29.

If a twenty-i'ive-cent coin is deposited in slot |1 bar 84 will be moved thereby to rotate cam carrier 94 a distance sufficient to cause cam 98 to disengagev plunger |08 from notched plate |02 and cause cam arm 99 to actuate movable chute section 3| to an advanced position wherein `notch |05 is aligned with plunger |08 so that when pin drops oi the end ||9 of cam 98 the lower end of plunger |98 will enter notch |05 to hold chute section Si in a position aligning the quarter acceptance channel and the quarter reject channel 52 with the upper stationary runway 28. If the deposited coin is a genuine twenty-live-cent piece the coin upon entering the magnetic ield of permanent magnets 29 and 3D will have its speed retarded sufficiently to direct the coin to the left of partition E0 to enter acceptance channel 5| and pass between endwalls 6B, 62 to strike gong 64 and then pass down between end walls 6|, 63 for discharge through exit opening 65. The path taken by a genuine twenty-ve-cent coin is indicated in Fig. 12 by the broken line |30. On the other hand, if the deposited coin is a twenty-fivecent size slug having a resistivity considerably greater than the resistivity of a silver coin, the slug upon entering'the field of permanent magnets 29 and 30 will have its speed retarded much less than the speed of the corresponding silver coin whereby the slug will be directedvto the right of partition 50 to enter the reject channel 52 for rejection through opening 13 in the manner shown for slug 8! in Fig. l5. The path taken by a twenty-ve-cent slug is shown in Fig. 12 by the broken line |3|.
