In telephone coincollectorsof the prepay type itlisnecessary that a, depositedcoin be held tem.- porarily, in suspense and. subsequently collected` or refunded, depending upon whether ,orjnot the desired' 'connectionL isr obtained. The apparatus` provide'dibythe presentinv'ention for performing.-

these functions has exceptional performance characteristics as will' be explained hereinafter..

`In a preferred' embodiment; of the invention a deposited coin isdirected into a coin hopper having a pivoted;l coin trap which is positively held; in,r coin supporting position by a latch controlled by a single coil electromagnet. The energizing circuit for the electromagnet is adapted to` be establishedr after the closure of electrical ycontacts controlled by av coin trigger actuated byv the deposited coin prior to reaching thek coin trap. e f

Below th'e coin trap are two coin channels, one leading to a cash box and the other leading to a refund'opening in the outer wall of the-.collector I holding latch for the coin trap and the releasedl trap discharges the coins into the refund channelor the collect channel depending upon tliel selective position of the coin vane due to-'the lreac tion between its permanent magnet and the specied pole-piece of the electromagnet. In the preferred embodiment the actuated armature not only releases the trap from its holding latch but K also strikes an extension of the trap topositively move the trap to coin discharging position. Both the refund channel and the collect channel preferably contain a lever actuated by the released l coin for opening the energizing circuit for the electromagnet whereupon all actuated parts of the mechanism are restored to normal.

The coin collecting and refunding mechanism just described has a number of outstanding features among which may be mentioned the selireleasing feature by which the device is restored to normal as soon as the deposited coin has been disposed of, making unnecessary any, release requirements on the relay structure; the independence of relay operating current on the coin;

load; the positive action of th'e coin trap under latch in locking the trap :in coin supporting position; and improved, protection afforded agains fraudulentv tampering;

As shown in Fig. 1 the type of coin collector in which this invention may be employed resembles in general theprepay coin collector disclosed in the US'S. patent to O. F. Forsberg` 1,043,219, issued November 5, 1 912. The upper housing I5 has a coin gauge I6 for receiving coins of various denominations and for directing them through individual coin channelsv in the multiple coin chute `I'I where they may be tested as to genuineness, and the spurious coins discarded. All genuine coins upon leaving the -coin chute I1 are directed into the mouth of a coin hopper I8 where they are temporarily held upon a coin trap I9 for subsequent collection or refund depending upon whether the desiredtelephone connection is secured; f l

'I'he coin hopper and relay mechanisms for disposing I'of the deposited coin or coins are disclosed in Figs. 3 to 11. Projecting into the mouth of the coin hopperis a pivotedcoin trigger 20 for actuation by the first deposited coin for clos-` ingin a manner subsequently described, the electrical contacts C; which are in series with the winding of a single coil electromagnet ZI. Below the coin trigger is a coin trap I9 for temporarily supporting the Ideposited coins. Trap I9 is pivotedl externallyof the hopper by means of av horizontal pin 22 and the external end of th'e trap carries a laterally arranged pin 28. This trap I9 is biased to its normal horizontal position by a coiled spring 2'I which has one end fastened to stationary tab 35 and the other end engaging pin 29 (Fig. 10) to hold the trap I9 against the top edge 31 of a slot in the hopper side wall. Trap I9 is locked in coin supporting position by means of a latch member 23 pivoted at its lower end at the point 24 while its upper end has a hook 2,5 engaging that portion of the horizontal pin 29 extending laterally from that end of the trap I9 remote from the coin hopper. Stationary pin 24 also carries a coiled spring 29 (Figs. 3 and 4) having one end fixed to the adjacent hopper side -wall with its other end pressing against one face of latch member 23 to bias member 23 to a position engaging pin 28 (Fig. 3). v y

Below the coin trap I9 is a coin vane 29 pivoted along the horizontal axis 39 and normally held in a substantially vertical position by a biasing spring 3| the lower end of which is fastened to the hopper wall at the point 32. As shown more clearly in the enlarged view of Fig. 4--A, vane 29 is made of sheet metal folded back on itself and located between the two portions of the vane near that edge of the vane adjacent the electromagnet 2| is an elongated permanent magnet 33 normally held in a Vertical position. The folded portion of the coin vane contains a slot 95 to permit the free end of biasing spring 3I to lie between the two portions of the vane. As shown particularly in Figs. 4 and 8 the coin hopper below the coin trap I9 is branched into a collect channel defined by walls 34, 35 and a refund channel dened by walls 38, 39; and it r will be noted from these figures that the opening into the refund channel 38, 39 is normally closed by the coin vane 29.

The rear wall 49 of the branched portion of the coin hopper has a laterally extending slot t0 receive a. horizontally disposed plate 43, one portion 4I of which closes the refund channel 38, 39 and another portion 42 of which closes the collect channel 34, 35. Plate 43 is pivoted externally of the hopper along the axis 44 `and has a suitable counterweight 87 external to the hopper for biasing plate 43 to a normally horizontal position. It will be apparent that any coin discharged from coin trap I9 will strike plate portion 4I or plate portion 42 and thereby deflect the plate downwardly whereby the discharged coin is free to continue on down the collect channel or refund channel as the case may be. This actuation of plate 43 by any coin discharged from trap I9 serves to open the en- .fw

ergizing circuit for electromagnet 2| as will be described hereinafter.

The solenoidal winding 2| of the electromagnet has a magnetic core fastened by kscrew 45 to the top 48 of a three-sided cover 49 of magi.

netic material which substantially surrounds the winding on all sides except the side adjacent the coin hopper. This cover which forms a part of the magnetic return path is suitably supported by three spaced ears 46, 59, 5I (Figs. 8 s:

and 19) projecting from the adjacent coin hopper. The armature for the electromagnet comprises a plate 52 having downwardly projecting flanges 53, 54 which are apertured to receive the pivoting pin 55 for the armature, the pin 55 being suitably supported by portions 58 and 59 of cover 49,

Armature flange 54 extends laterally beyond the cover 49 and then upwardly to form a substantially vertical arm 50 for performing several desired functions when the armature is attracted by the electromagnet. The said armature'is biased to its non-operated position by a spring 6I which extends between a lower portion of cover 49 and a lug 62 forming a part of flange 53 remote from the pivoting axis of the armature. The relay cover 49 at its bottom edge has a horizontally disposed tab 'I8 acting as a stop to denne the released position of the armature since one portion of flange 53 normally rests on tab 'I8 as shown in Fig. 3.

The core of the electromagnet has an angular pole-piece extension 63 (Fig. 5) terminating in a horizontal portion 64 lying against side wall 65 of the coin hopper adjacent the upper end of bar magnet 33 but laterally offset therefrom as shown in Fig. 4. Therefore, whenever the electromagnet is energized the polarity of pole-piece E4 will determine whether or not the upper end of bar magnet 33 is attracted or repelled. For one direction of current flow through the winding of electromagnet 2l, pole-piece 64 and the upper end of bar magnet 33 will be of the same polarity and the bar magnet will be repelled tend'- ing to move vane 29 in a counter-clockwise direction as viewed in Fig. 4 to cause the upper end of vane 29 to be forced against the shoulder 66 formed in a wall of the coin hopper. For current iiowing through the electromagnet in the opposite direction bar magnet 33 will be attracted so that vane 29 will be moved to the broken line position 29 of Fig. 11. The reaction between bar magnet 33 and pole-piece 64, therefore, serves to bias vane 29 to a position determined by the polarity of the voltage applied to the single coil electromagnet 2I and this biasing insuresthe desired collection or refunding of the deposited coin as will be described hereinafter.

Mounted on the cover plate 49 but insulated therefrom are two sets of electrical spring contacts C1 and C2. Spring contacts C1 are normally biased to open position. Associated with spring contacts C1 is a biasing spring 68 which is adapted to close contacts C1 but is normally restrained from so doing by spring end ,69 resting against shoulder 'I0 of the coin trigger 29 as shown in Fig. 3. However, when the coin trigger is actuated bya deposited coin the said shoulder 'I0 is moved upwardly out of the path of spring end 69 and hence spring 58 is permitted thereby to close contacts C1 as shown in Fig. 7; and spring end 69 now occupies (Fig. 7) a position beneath shoulder 'I0 to temporarily prevent coin trigger 29 from being restored to normal by its counterweight 19.

Contacts C2 are also biased to open position and the associated spring member 'II is biased for movement away from contacts C2 but spring II is normally held in contact closing position by spring extension 'I3 resting against an insulating stud 'I2 (Fig. 3) carried on the armature extension 65. The actuation of armature 52 serves to remove stud 'I2 from the path of biasing spring 'II but the end 'I4 of the spring thereupon strikes a cam surface 'I5 on plate 43, in which new position spring It still maintains contacts C2 closed. However, whenever plate 43 is tilted downwardly by the passage of a coin discharged from trap I9, cam "i9 is moved upwardly as shown in Fig. l0 to enable spring 'II to move far enough away from contacts C2 to permit them to open.

As shown in Fig. 2 the two sets of contacts C1 and C2 are connected in series with each other between ground and the winding of the single coil electromagnet 2I, so that both sets of contacts must be'closed to establishan energizing circuit for the electromagnet and the opening of either pair'of contacts will cause the electromagnet yto be' deenergized.

Armature extension 6D has a laterally extending lug 80 which upon armature attraction contacts with an intermediate portion of latch member 23 to release pin 28 from hook 25 whereby the coin trap I9 is free to drop downwardly to coin discharging position providing the coin load-'is suiicient to overcome the restoring spring 21 for the coin trap. However, positive coin dumping' is assured after the release of latch 23 since 'pin28 is subsequently positively moved upwardly by described below.

' The vertical armature 'extensionGIl at its upper end also carries a stud 11v which performs no function when the armature is in normal position but when the armature is attracted Afor movement about its pivot 55, stud 11 isswung in an arcuate path which brings the stud to -bear agaista bowed portion 18 of fthe left spring member of contacts C1 to force the pair of vspring contacts to the right as shown in Fig. whereby contacts C1 which were closed by the ractuation of Vthe `coin trigger are still -maintained closed but the spring pile-up (comprising spring contacts C1) in its new position removes spring 'end 69 from vbeneath trigger shoulder 1`II to permit the triggerto restore to 4normal due to its counterwight 19 so that the subsequent release of armature 52 will again cause contacts l'C1 to be opened because shoulder 10 would now be interposed in thep'ath of spring end 69.

The manner in which the above-described apparatus operates to collect-or refund a deposited coin will now be described in detail. In the vfol` lowing description it will be assumed that the telephone line 85 of Fig.`2 which is connected to the coin collector of Fig. 1 is a calling line and extends to a central office containing apparatus for connecting this calling line to a desired or called line. Y

Assuming it is desired to make a local call from the telephone coin collector disclosed in the above gui'es, a rive-cent piece is deposited infcoi'n gauge I6 and the coin after sucoessfullymeetihg certain tests as to genuineness while traversing coin chute I1 will drop into coin hopper I8' and come to rest on coin trap I9 since the'trap is positively held in` coin supporting position by latch-member 23 (Fig. 8). Before reaching coin trap I9 the coin strikes coin trigger 20 'whose normal position is shown in Fig. 3 and thecoin trigger in ybeing actuated toits lowerinos't posi# tion of Fig. '1 releases biasing springv 58 to close contacts C1. Since the other set of contactsC are normally closed the coin operated closure o f contacts C1 serves to connect one terminalof vthe electromagnet winding 2I to ground throughboth sets of contacts in series as shown`infFig.2 'so that one side off the telephone -11ne is g'runded through said winding.- Apparatus at the central ofce isthereupon prepared in the usual manner to extend the calling line tothe desired called line as determined by pulses transmitted by a calling dial 84. If the desired connection is obtained means at the central oflice are operated to apply battery to line 85 vof such polarity that the-depositedcoin is collected. In the present instance l it hasbeen assumed that channel 34, leads to the usual cash compartment inthe lower housingy B'I and hence to insure collection the appliedV voltage should be of that polarity which causes rpole-piece 64 to repel bar magnet 33, biasing vane 29 against shoulder 66, in which position the said vane closes the opening to the refund channel 38,39 vand lies out ofthe path taken by coin trap I9* in reaching its coin discharging position. This biasing of vane 29 takes place im- -r'nediately upon the application of collect current andbefore'armature 52 has been moved'an appreciable distance from its non-operated position. The position of armature 52 with the elec tromagnet deenergized is vshown in Figs. 3, 4 and 6. f In Fig.` 8 there has beena substantial' upwardA movement of the armature while the said' armature is shown in its fully attracted position in Figs. 9 and 10, thev armature movement taking place aboutits axis 55 in a counter-clockwise direction as viewed in Fig. 8.

l Several mechanical operationsare produced by the movement oftheV armature 52 to its attracted position. `I .Yug 12 at thelower end of armature extension 6 0 is moved out of the path of spring end 13 but contacts Cz are still held closed since spring 1I is still restrained because spring end k 14 'now restsagainst cam 16 which is a part of pivoted plate 43. Lug. 80' fastenedto an intermediate portion oarm 60 strikes latch member 23 vto release trap I9 well before the armature movement has been completed. After lug 89 has freed pin 28 from latch 23 the continued movement of arm 6I) brings cam surface 82 into contact withpin 28 so that pin 28 on entering 21. 'With the trap I9 moved from its horizontal position of Fig. 8 to its discharge position of Fig. 9.any coins on the trap will fall `directly on pivoted plate `portion 42 and tilt the said plate to its lowermostposition 42' of Fig. 10 whereby tl'iercoin freelyA passes down `collect channel 34, 35 to the cash box located in the lower housing 86 of the collector (Fig. 1). y trap I9 have passed beyond plate portion 42 the said plate portion tends to return yto its normal horizontal position under the action of its counterweight 81 but is temporarily restrained from so doing since spring end 'I4 now lies against the upper curved surface 88 on the lower edge otcam 'I6 whereby spring end 'I4 holds plate portion 42 tilted slightly downwardly, say, in its upper position of Fig. l0.`

However, the tilting of plateportion 42 frees spring 1I of the restraining action of cam 16, thereby enabling the contacts C2' to be opened to deenergize electromagnet 2 I. With the circuit so interrupted the holding force of the magnetic system is limited to Yresidual forces andv iseasily overcome b-y the restoring force supplied by the biasing spring 6I. The armature 52 is, therefore, restored to vnormalvby its biasing spring 5I to remove* arm 69' from engagement with spring 18, latch member 23 and` pin 28. Contacts C1 After all coins `from Y are `thereuponopened since'ishoulder 'l0 of the coinltrigger 20 is now in .position `to prevent the biasing spring 68 from closing contacts C1. Spring 2l is now free to restore trap I9 to `its horizontal position of Fig. 8 whereupon it again is locked in coin :supporting `position by latch member 23 since biasing spring -25 is now effective to move hook over pin V'28 as shown inFigs. '7 and 8. The movement of arm 4Iii! back to its normal position also brings stud 'l2 again into engagement with spring portion 73 to force the spring pile-up comprising spring contacts C2 to the right as viewed in Fig. V10 so that the spring pile-up is brought into its normalcondition of Fig. 3 with contacts .C2 closed.

The above description has assumed that itis desired to collect the coin or coins on the .trap

I9. If, however, Vit is desired to refundthe. depos.

ited coin the refund battery current applied at the central cnice will be of the opposite polarity to that assumed above whereby there will be mutual attraction instead of repulsion between bar magnet 33 and pole-piece 64, the attractive force being sufficient to move vane 29 from its normal position of Fig. 4 to its broken line position of Fig. 11 against the restoring force exerted 4by spring 3|. As shown in Fig. `11 this movement of vane 29 to a point adjacent polepiece 64 brings the upper end of the vane well withinlthe downward path of trap E9 and trap I9 under the positive action of arm 60 drives vane 2S .to the full line position of Fig. 11 whereby the coins on trap I 9 will be deflected into refund channel 38, 39 which as in the'usual collector directs the coin down into the lower housing to a pocket adjacent a refund opening in the front wall of the housing. Except for the different position taken by vane 29 the operation of all moving parts upon the application of refund current is the same as that `previously described for the .application of collect current. In this connection it will be noted that plate portion 4l in the refund channel is integral with plate por tion 42 in the collect channel and hence the refunded coin in striking plate portion 4I to tilt A lect current orrefundcurrent, it is desirable that d armaturev extension 6l) perform its functions in the following sequence: (l) releases latch 23; (2) positively forces trap I8 to coin discharging position; and (3) permits the trigger 2D to be restoredto normal. Tlns sequence lprecludes the possibility that the collect or refund current might be applied for such a short time interval that the trigger 20 .might `be reset to open the circuitof the relay without dumping the coins on the coin trap, whereby the deposited coin would remain on the trap until the next coin is deposited and the collect or refund current applied for a longer time interval. In the present invention the coin trigger 20 cannot be reset to open the 'circuit of the relay until after the trap has been moved to coin discharging position; and the application of collect or refund current for a time interval too short .to .discharge any coin on trap 1.9 will Akeep trigger 23 in actuated position with coin .collection or .refund still under control of the remote central oilce without the vnecessity of depositing -an additional coin.

In the `above construction itis assumed that the coin hopper AI3, as shown in Fig. 4, is suitably inounted on an-apparatus tray `t?! of thecoin collector, this tray having anopeningfg leading to the `refund channel in the lower housing and an opening 9| leading to -the cash box. It has previously been described that the electromagnet 2| isisupported from the coin hopper instead of being supported on the apparatus tray as in the construction `of the above-mentioned Forsberg patent.

- The `force and load characteristics of one particular embodiment of the disclosed magnetic system may -be described as follows: The system was so designed that for a current of .O45 ampere through the coil of the electromagnet the forces were sucient to overcome the load which initially consists of the weight of the armature 52, armature extension 60, the tension of restoring spring 6| and whatever friction is involved. As the air-gap shortens with the upward movement of `the armature the operating forces increase rapidly and at a point just before the latch 23 is engaged by arm a `force of 240 grams is available resisted by a load of about grams. The load then increases abruptly to about 150 grams due to the latch spring 26 and friction and a short time later decreases to about grams when the latch releases. When the coin trap pin 28 is engaged by arm 60 the load again increases to about grams, but by this time the operating force has increased to 275 grams. Thereafter the load increases to its final value of 210 grams and the operating force increases to 850 grams. These excesses of armature forces over loads at the lgiven positions of the armature are of such magnitude that positive operation is insured even under the adverse .conditions occasionally encountered in the field. After the current has been interrupted the residual holding forces lare very low and are easily'overcome by the restoring spring system which comprises the major portion of the 210-gram load.

It may be noted from the above description that the self-releasing feature of the magnetic system due to the coin operated opening of contact C2 by means of which the device is restored to `its initial condition as soon as the coins have been properly disposed of, makes absolutely unnecessary any release requirement for the relay. The operating current is alsoindependent of the coin load since the coin load is not picked lup'by the armature until near the completion of its stroke. The positive action of the coin trap IS! under the lightest coin load is also an important feature of this invention. Other advantageous features are the positive return of the trap I9 to normal; the positive action of the latch '23 in locking the trap incoin supporting position thus eliminating the possibility of premature operation as coins are dropped on the trap; the sequence of events by which the resetting of coin trigger 20 is not possible until the coins have been disposed of; and the inherent protection afforded against fraudulent tampering.

1With respect to the llast-mentioned feature of protection against fraudulent tampering Vit will generally be preferable that the winding of the electromagnet be so connected that the talking battery current will tend to bias vane `29 .in the same direction as produced by the application of collect current so that any fraudulentattempt to effect premature operation-will result in the collection of the coins on the trap.
