Definitions
- the usual collector contains a multiple coin chute for receiving coins of various denominations and for guiding the coins first to a suitable sound signal and then to a coin hopper where they are temporarily held for subsequent collection or refund.
- This invention is primarily concerned with the rejection from the chute of slugs whose electrical resistance is substantially different from that of a standard coin.
- theinvention is illustrated as applied to the rejection from the nickel runway of slugs of'lower electrical resistance than a standard nickel, and to the rejection from the twenty-five -cent runway of slugs of higher electrical resistance than a standard quarter.
- the chute assembly contains a chamber into which nickels and quarters are laterally projected in opposite directions after traversing the field of a separate eddy-current magnet for controlling their speed of projection in accordance with their electrical resistance.
- the bottom portion of this chamber contains two coin outlets, one leading to a reject channel and the other leading to an acceptance channel, with the first outlet adjacent'the point where the nickel enters the chamber and with the second outlet adjacent the point where the quarter enters the chamber.
- the speed of projection of astandard nickel is preferably such that the coin leaps over the first outlet and into the second outlet while the speedof a quarter is retarded sufliciently by its eddy-current magnet to divert the quarter into the second outlet.
- Such an arrangement diverts standard quarters and nickels' into the same channel wherein they 'must be separated to enable adeposited quarter to strike a different sound signal from a deposited nickel.
- One of the Walls of this acceptance channel preferably contains an elongated opening so related to the channel that a deposited nickel will fall therethrough into a nickel channel leading to the nickel signaling device While a d'epositedquarter being of greater diameter will continue on past this opening to engage the quarter signaling device.

depending uponconditions occurring after deposit. The usual collector contains a multiple coin chute for receiving coins of various denominations and for guiding the coins first to a suitable sound signal and then to a coin hopper where they are temporarily held for subsequent collection or refund.
This invention is primarily concerned with the rejection from the chute of slugs whose electrical resistance is substantially different from that of a standard coin. In the specific embodiment disclosed in the attached drawings theinvention is illustrated as applied to the rejection from the nickel runway of slugs of'lower electrical resistance than a standard nickel, and to the rejection from the twenty-five -cent runway of slugs of higher electrical resistance than a standard quarter. In order to obtain this result the chute assembly contains a chamber into which nickels and quarters are laterally projected in opposite directions after traversing the field of a separate eddy-current magnet for controlling their speed of projection in accordance with their electrical resistance. The bottom portion of this chamber contains two coin outlets, one leading to a reject channel and the other leading to an acceptance channel, with the first outlet adjacent'the point where the nickel enters the chamber and with the second outlet adjacent the point where the quarter enters the chamber. The speed of projection ofastandard nickel is preferably such that the coin leaps over the first outlet and into the second outlet while the speedof a quarter is retarded sufliciently by its eddy-current magnet to divert the quarter into the second outlet. With such an adjustment of the strength of the two eddy-current magnets relative to the two outlets it will be apparent that a nickel slug of substantially lower electrical resistance than a standard nickel will be retarded sufficiently'more than the standard coin to cause the slug to be diverted into the first outlet while'a twenty-fivecent slug of higher electrical resistance than a standard quarter will have sufficiently greater speed than the standard coin to leap over the second outlet and into the first outlet.
Such an arrangement diverts standard quarters and nickels' into the same channel wherein they 'must be separated to enable adeposited quarter to strike a different sound signal from a deposited nickel. One of the Walls of this acceptance channel preferably contains an elongated opening so related to the channel that a deposited nickel will fall therethrough into a nickel channel leading to the nickel signaling device While a d'epositedquarter being of greater diameter will continue on past this opening to engage the quarter signaling device.

For illustrative purposes the telephone coin collector shown in Fig. 1 may be assumed to" be of substantially thesame general type of prepay telephone coin collector as shown in the O. F. Forsberg U. S. Patent 1,043,219 in which a legitimate coin such as a nickel, dime or quarter after deposit in a coin gauge ll mounted on top of the upper housing 12 is selectively directed into the proper channel of a laterally inclined coin chute assembly 3 for actuating a sound signal before reaching a coin hopper M where the deposited coin is held in suspense for subsequent collection or refund depending upon conditions occurring after deposit. v
The present invention is primarily concerned with the rejection of non-standard slugs from the coin chute where their-rejection is secured by means of eddy-current magnets which are used to discriminate against slugs having an electrical resistance substantially different from that of a standard coin. The eddy-current magnets used for this purpose are generally of such strength as to hold. in the chute any slug of magnetic material which enters the fields of. these magnets so that it is desirable to provide means for'preventing'magnetic slugs from reaching the coin' channel sections adjacent the eddy-current magnets.
In order to conserve space within the upper housing |2 it is preferable to make the magnetic slug rejector a part of the multiple coin gauge I mounted on top of the housing I2. One form the magnetic slug rejector may take is disclosed in my copending application Serial No. 363,237, filed October 29, 1940, and is also shown in Figs. 2 and 3 of the present drawings. A sectional view of the coin gauge H is shown in Fig. 3 where the sectional view may be assumed to be taken at the center of either the nickel, dime or quarter openings in the coin gauge shown in the front View of the gauge of Fig. 2.
tional view along the center of the nickel opening in the coin gauge H. Behind the rear wall I5 of the nickel coin slot is a chamber containing a pivoted member l6 mounted for rotation about a pin l1 and carrying a U-shaped permanent magnet l8. When a magnetic slug is deposited in the coin slot the mutual attraction between the slug and the magnet will attract the magnet I8 towards the slug until the magnet is stopped in its forward movement by wall l5 and this ad- Vance of the magnet causes a lateral arm I!) on member |6 to move forward from its normal position of Fig. 3 to an advanced position blocking the bottom opening of the coin runway so that arm l9 acts as a barrier to the entrance of the magnetic slug into the coin chute I3, and hence the magnetic slug will have to be manually removed, from the coin gauge before a legitimate coin may be deposited. It further may be assumed that gauge II has a similar pivoted magnet of the above description for each of the nickel, dime and quarter coin slots so as to provide a barrier against the entrance into the housing of any slug containing magnetic material.
The coin chute assembly, a rear view of which is shown in Fig. 4 and an end view of which is shown in Fig. 9, comprises a cover plate 25, a dime channel plate 26, a combined nickel and quarter channel plate 21 and a nickel channel plate 28. The dime channel plate 26 is shown in Fig. 5 with the cover plate removed; the nickel and quarter channel plate 21 is shown in Fig. 6 with plates 25 and 26 removed; and the nickel channel plate 28 is shown in Fig. '1 with plates 25 and 26 removed, while still retaining a portion of plate 21.
Near the upper portion of the chute assembly are four eddy-current magnets, magnets 3|) and 3| being for the nickel runway and magnets 32 and 33 being for the dime and quarter runways. The magnet 30 is suitably mounted on plate 21 at a point above the upper end of the nickel plate 28 with the magnet passing into apertures 34, to enable the pole faces of the magnet to lie flush with the front face of plate 21. The other nickel eddy-current magnet 3| is suitably mounted on cover plate 25 and the magnet passes into apertures 36, 31 in the dime plate 26 to have its pole faces flush with, the rear face of plate 26 as viewed in Fig. 8. The dime and. quarter eddycurrent magnet 32 is suitably mounted on plate 21 with its pole faces resting against the rear face of plate 21 as shown in Fig. 8. In Fig. 6 it may be assumed that the dotted rectangles 38, 39 represent the two ends of magnet 32. The other dime and quarter eddy-current magnet 33 is suitably mounted on the cover plate 25 with the pole faces of the magnet flush with the outer face of cover plate 25 as shown in Fig. 8. The
For illustrative purposes it may be assumed that Fig. 3 is a secby the standard relative positions of the two eddy-current magnets for the dime and quarter runways are, therefore, indicated by the rectangles 38, 39 of Fig. 6 or rectangles 40, 4| of Fig. 5, while the relative positions of the eddy-current magnets for the nickel runway are indicated by the apertures '34, 35 of Fig. 6.
F The complete dime runway is shown in Fig. 5
where a deposited dime after leaving the coin gauge l drops into a coin channel between cover plate 25 and the dime plate 26 to follow a path indicated generally by arrows 42, 43 and 44 to strike the upper and lower edges of bell 45 before dropping into the coin hopper l4. A deposited dime in rolling down the longitudinally inclined ledge 46 passes between the eddy-current magnets 32, 33 near the lower end of this ledge; and the strength of magnets 32, 33 is preferably such as to slow up the speed of the deposited dime so that its projected velocity upon leaving the lower end of ledge 46 is insufficient to enable the coin to leap over the dividing point 41 so that the dime drops downwardly between dividing point 41 and ledge 46 to follow the legitimate coin channel defined by guide rails 48, 49 wheredime follows the path indicated by arrows 43, 44. On the other hand, a deposited ten-cent slug of substantially higher electrical resistance than a standard dime will not be appreciably slowed up when passing through the fields of magnets 32, 33 but will be projected with sufiicient velocity to leap over dividing point 41 and be directed out of the chute assembly by falling through opening 5|! in plate 26 and opening 5| in plate 21. In the rejection of such a slug the lower edge of the slug rides on tabs 41 and 52, and ledge 53 to reach the reject opening 56.
The combined nickeland quarter channel plate 21 is disclosed in Fig. 6. A deposited nickel after passing through coin gauge drops between plates 26, 21 to follow a coin channel indicated by arrows 54, 55, after which the bottom edge of the coin rolls down the longitudinally inclined coin track 56 of plate 21. Plate 21 above track 56 has an elongated opening 58 which serves to divert a nickel into a separate nickel runway lying between plate 26 of Fig. '1 and the rear face of plate 21 of Fig. 6. As the bottom edge of a nickel rolls down track 56 the upper edge of the nickel drops through opening 58 and is supported by plate 28 as shown by nickel 60 in Fig. 11. When the bottom edge of the nickel reaches the lower end 51, the nickel passes completely into the nickel channel between plates 21, 28 to follow the path indicated by arrow 6|, Fig. '1, to strike the lower edge of bell 45 after which the coin drops into hopper l4. It will be understood, however, that a standard quarter, being of larger diameter than a nickel, will not enter opening 58. It will also be noted that plate 28 has the usual underdiameter reject opening 59 for rejecting from the chute assembly any slug of smaller diameter than a nickel.
It will be noted that in the upper portion of the nickel runway-a deposited nickel rolls down along a longitudinally inclined ledge to pass between the poles of eddy-current magnets 30, 3| and to be projected from the lower end of ledge 65 with suflicient speed to pass to the right of the dividing point 52 as indicated by arrow 55 to follow the legitimate coin channel previously described. On the other hand, a nickel slug having a substantially lower electrical resistance than a standard nickel in traversing the field of mama-so eddy-current magnets '38, 31 will .be retarded to a greater .extent than .a standard coin and hence will be .unable to leap over the dividing 'point 52 but will be deflected to the left'to follow a path indicated by arrow 61 of Fig. 6 whereby Such a slug is rejected through said wall opening A deposited quarter after dropping through the coin gauge U will enter a coin channel between plates 26 and 21 and will roll down a longitudinally inclned ledge 68 for projection through the fields of the eddy-current magnets 32, 33. Since a silver coin has a relatively high electrical conductivity it follows that the deposited quarter will be substantially retarded upon entering the fields of the eddy-current magnets 32, 33 and the fields of these magnets are preferably of such strength that the quarter will have insuflicient speed of trajectory to leap over dividing point 52 but instead will follow the path indicated generally by arrows 69, 10 and 55. Astandard quarter, being of a greater diameter than a nickel, will not be diverted through the nickel opening 58 but will continue past opening 58 to strike the quarter gong signal 18 and then follow the path indicated by arrow H for discharge into the coin hopper l4.
On the other hand, if a quarter slug of substantially higher electrical resistance than a legitimate quarter is deposited in the quarter runway, such a slug will not be retarded to any substantial extentby eddy-current magnets '32, 33 but will be projected from ledge 68 with sufficient lateral velocity to leap over dividing point 52 for rejection through opening 5| as indicated by arrow 12 of Fig. 6.
As a summary of the foregoing description of Figs. 6 and '7, a genuine nickel will be projected from ledge .65 with suffic'ient velocity to pass into the acceptance channel lying between dividing point 52 and ledge '13 while a standard quarter upon leaving ledge 68 will be retarded sufficiently to cause the coin to be diverted into the same acceptance channel between dividing point 52 and ledge 13; a nickel slug of lower electrical resistance than a standard nickel will be diverted into the reject channel lying between dividing point 52 and the lower end of ledge 65 where ledge 14 prevents the rejected slug from entering the section of the acceptance channel containing opening 58; and a quarter slug of higher electrical resistance than a standard quarter will leap across the acceptance channel into said reject channel and out through opening 5|.
The dividing points 41 and 52 will now be described in further detail. As shown in, Fig. 4, the cover plate 25 has an enlarged aperture 15 to permit the mounting on the dime channel plate 26 of two metal strips 1B, 11, each strip being held in an adjusted position by screws such as screw 18, which pass through elongated apertures in the strips. Strip 16 has a lug 52 (see Fig. 10) which projects laterally across the space between cover plate and the dime channel plate 26 and across the space between the dime plate 26 and the nickel-quarter plate 21 .to abut against the inner face of plate 21 to serve as shown on Fig. 6 as a dividing point between the reject channel leading to opening 5| and the 1 acceptance channel including the coin track 58. Similarly, strip 11 has 2, lug 41 which projects laterally across the space between the cover plate 25 and the dime plate 26 to serve as a dividing point between the reject channel leading to opening and the acceptance channel indicated by arrows 43, 44 on Fig. 5.
As shown :on 6, the coin supporting ledge 58 cbnstitutes a part of a separate member :88 mounted on plate'f z2l by a screw 8| which passes through a slot 82 "in member 80.
In adjusting the device for maximum discrimination against dime slugs having a somewhat higher electrical resistance than a standard dime, lug 4! should be adjusted to such a position that a standard dime will just fail to pass over lug 41 into the reject channelleading to opening 58. crimination against slugs having a somewhat lower electrical resistance than a standard nickel, metal strips 16 should. be adjusted to such a position that a standard nickel coin will just be able to pass over lug 52 into the acceptance channel 52'|3; and with lug 52 in this optimum position for the acceptance of nickel coins the ledge 68 should be adjusted to such a posi- It will be undertsood that this invention is capable of other embodiments commensurate with the scope of the appended claims.
