distance service, it is desirable to insure that before service may be obtained through such station the proper coin or coins shall be deposited and collected therein. It is further desirable that the collections made for local service shall be segregated from the collections made for long distance service and that the collection of coins shall occur at the time service is rendered.

In our copending application, Serial No. 503,- 952, filed December 22, 1930, we have disclosed an automatic pay telephone station in which local and long distance collections were accomplished at the time the service was rendered by employing relays within the pay telephone stae tion structure to segregate the coins collected and to insure holding the coins in abeyance until the desired service was rendered. 7

Another object of the invention is to provide a. pay telephone station in which coins, when deposited, will be refunded to the depositor if the desired service cannot be obtained, and which, if the desired service is obtained, will permit operation of the telephone for only that service for which the coins were initially deposited.

Another object of our invention is to provide a pay telephone station in which both local and long distance collections may be obtained in a positive manner, and in which the internal construction of the pay telephone station to accomplish these results may be simplified. I

Other objects of our invention will be apparent from a study of the following specification, read in connection with the accompanying drawings, wherein Figure l is a front elevational view of a pay telephone station constructed in accordance wit our invention;

Referring to the drawings, we have illustrated w ken. alon in Fig. l a pay telephone station comprising a box-like housing 1 to which is attached'a front cover 2 in d a at on e of the ho sing and arranged to be held in closed position by means of a locl; 4. The cover Qhas mounted ther on he talkin is n n andt l phonc so.- l tins ppara s indic t d r sn c v n a transmitter 5, a receiverii secured'upon the hoolg l, and a dial selecting device 8 of the usual con struction employed in automatic telephone sta tions.

R f r in particularly, to F 2. t will. e o served that upon the inside of the cover 2 are mounted the usual transformer a, employed in connection With telephone an o the rinsing apparatu :0. t W111 al o b ved hat the hop}; 1 is pivoted as at H (see Fig. 3), in such manner that the inner arm 12 of the hook pro: jects inwardly of the cover 2, to engage and oper-, ate the usual hook switch mechanism [3.

The housing l is illustrated as being provided with coin. col ect n and refundin appa tus nelud n enera l a c n guide 4 u per p rti n of whi t nds upwa dly and outwardly of the housin and is pr d d'on' ts i cnt face with a p u ality o ir ula openin s 5,. l5 and ea h of th p oper diamete t accommodate a pa t cular will pr s n i a p rtion of the ll c s or s r e by the t lep one stat on,- For e amp the 011 111 9 5 may be o mproper diameter to just receive a 25 piece or quarter of a dolla t e ir ula ope i constitu i g a sa pr ve t n he inser io f a coi of g eater diameter; the circular opening it may be adaot o ill beadapted to receive niokels or pi The coin guide [4 is illustrated as being provid municates with the opening l5; the slot |9 oommunicates with the opening I 6; and the slot 20 communicates with the opening By referring, particularly, to Figure 2, it will be observed that the coin guide |4 terminates immediately above a transfer basket 2| pivoted to a suitable frame 22 which may be formed of a casting either constituting a part of the coin guide M or separate therefrom. The transfer basket is illustrated as constituting an elongated bar extending transversely of the lower end of the guide 54 and is provided with a slot extending therethrough aligned with each of the slots i8, i9 and 29 in the guide I4. That is, the basket 2| is provided with a slot 24 which extends vertically in alignment with the slot I8 through which the 25 coins pass. The slot 25 is aligned with the slot 59, while the slot 26 is aligned with the 5 slot 29.

The basket 2i is illustrated as being provided upon one of its ends with a pin or trunnion 21 which extends th ough a suitable opening in the casting or frame 22 so that it forms therewith a trunnion bearing permitting movement of the transfer basket about a horizontal axis. The opposite end of the transfer basket 2| is pivotally secured to the frame 22 as by means of an adjustable set screw which extends through a portion of the frame 22 in alignment with the pin 2?. Thus the transfer basket 2| is arranged to move upon its horizontal pivots from a rearward position to a forward position.

In the rearward position, as is illustrated in Figure 6, the transfer basket 21 is aligned with a coinrefund chute 29 which extends laterally, as is shown in Fig. 2, across that portion of the transfer basket 2| which includes the slots 24 and 25. This refund chute 29 extends laterally and downwardly of the housing to terminate in a coin refund chamber 39, the lower end of which is provided with a flanged plate 3| constituting a guide through which coins may be projected toward the front of the housing and into the coin receptacle 32 so that such coin may be removed with a 25 chute 35, a 10 or dime chute 31, and

a nickelvor 5c collection chute 38, all three chutes constituting a coin maze of the character now employed in pay telephone stations for the collection of the respective denomination coins.

The transfer basket 2| is arranged to move to its forward or rearward position as follows: a rod 39 is illustrated as being journalled to the frame 22 within the housing I, as by means of a bushing through which the rod 39 is adapted to slide forwardly and backwardly relative to the housing The forward end of the rod 39 is provided with a head 4| adapted to be engaged by one end of a lever 42 pivoted as at 43 to the front cover 2 of the housing i so as to be engaged and moved inwardly of the cover by the extend- .1 end i2 of the receiver hook I when the receiverfi is on the hook. The amount of movement permitted the lever 42 may be regulated by means of a set screw 44 threaded into the lever 42, the head of which is adapted to be engaged by the end I! of the hook 1.

Extending upwardly and rearwardly from the rod 39 is a second rod 45, rigidly attached to the rod 39 and having its inward end 45 receivable in a slot 41 in the front face of the transfer basket 2|. Hence when the receiver is located on its hook, the pin 45 will insure the basket 2| being in its rearward position, while when the receiver is lifted from the hook the forward movement of the pin or rod 45 will permit the transfer basket to swing forwardly to its forward position.

Hence with the receiver on the hook any coins which might be deposited in either the dime chute or the quarter chute will pass immediately to the return chute and be refunded to the depositor.

Extending horizontally across the rear of the refund chute 29 and the local collection chute 94 is a bar or rod 48 which is illustrated as being supported for rotary movement in a tube 49 suspended as by means of clamps or brackets secured to the rear of the coin refund chute 29.

By referring, particularly, to Figure 4. it will be observed that the right hand end 5| of the bar 48 is turned downwardly in a position to engage the inner end of the rod 39 so that whenever the rod 39 is pressed inwardly (as by reason of the receiver 5 being upon its hook I) the end 5| of the rod 48 will be pressed rearwardly.

Immediately behind the local collection chute 34, a pin 52 is rigidly secured to the rod 48, the upper end 53 of the pin 52 being bent forwardly as is indicated in Fig. 5 to project between the lower end of the nickel chute 20 in the coin guide M and the slot 26 in the transfer basket 2! so that at all times when the receiver is on its hook the pin 52 will obstruct the passage of a coin through the transfer basket 2|. The purpose of this construction is that should a person inadvertently deposit a nickel in the 5 slot before lifting the receiver from the hook. the coin would not be immediately returned to him nor would it be collected, but it would be held in abeyance until the receiver was lifted from the hook, whereupon it would pass into the local collection chute to effectively connect the telephone station for the local service.

By referring again to Figure 2, it will be observed that the right hand end of the transfer basket 2| is normally prevented from swinging to its forward position by reason of the engagement of a pin 54 with the forward edge of the basket 2|. The pin 54 is illustrated as being slidably mounted upon the frame 22, the right hand end of the pin 54 being engaged by a lever 55 pivoted upon a projection 55 which bears against the frame 22. The pin 54 is normally held in its projected position by means of a spring 51 secured upon a screw 58. The opposite end of the lever 55 is illustrated as being normally in contact with a rotatable shaft 59 which constitutes the shaft of a switch operating lever 60. (See Fig. 9).

Referring again particularly to Fig. it will be observed that the local collection chute 34 has a slot 6! cut through one of its sides, through which projects one end of the lever 50, into the path of a coin (represented by dotted lines -62), descending through the local collection chute 34. The lever 69 is rigidly secured to its shaft 59 so that movement of the lever is accompanied by a corresponding rotation of its shaft 59. The other end of the lever is provided with an insulating bushing 63 so positioned as to engage and operate the contacts ofa switch 54 arranged as is hereinafter described to renderthe tele-. phone station operative when actuated; v,

The function of the pin 54 and the switch operating lever 55 is particularly adapted to the operation of our telephone station for completing calls for local service wherein the person desiring to use the phone is required to deposit a 5 coin before such service is permitted. It is desirable in such service that no effective cone nection be obtained until the deposit of the coin and that in the event of completing the call the coin should-be collected while if the call cannot becompleted, either because the called station does not answer or is busy, or because the line is out of order, the coin should be returned to the depositor.

7 By referring, particularly, to Figs. 4 and 5, it will be observed that in addition to the obstruct-v ing effect of pin 53 to the passage of a 5 coin, the collection chute 34 is provided with twoadditional obstructions, the first comprising a pin 55 projecting through an opening 55 in the rear wall of the chute 34, while the second comprises a pin 6'! projecting through an opening 58 in the front wall of the chute 34.

The pin 55 is employed to arrest a coin passing through the local collection chute 34 until such time as the call is either completed or until it is definitely ascertained that the call cannot be completed. 1

The pin 55 is illustrated as being secured to a lever 59 pivoted at one of its ends upon a pivot pin '10 for movement about the pivot from a position illustrated in Figure 5, in which the pin 55 is in chute-obstructing position, to a rearward position in which the pin 55 is removed from the chute.

The upper end of the lever 69 is illustrated as passing immediately behind the rod 48 in a position to be engaged by a depending pin '1! secured to the rod 43 and movable .therewith. Hence, whenever the rod 48 isrotated to its rearward position, as when the receiveris on its hook, the pin II will move the lever 69 to its rearward position and thus remove the pin 55 from the local collection chute.

' The lower pin 61 is illustrated as being supported upon a strap 12 which extends around the chute 34 and is rigidly secured to a lever 13 also pivoted upon the pivot 15 and having its upper end '54 bent forwardly and inwardly to en-' gage the forward side of lever 59 so that whenever the lower end of the lever i3 is moved forwardly the lever 55 will be moved rearwardly, thus removing both. of the pins 55 and 51 from the chute 34.

The lever 13 is illustrated as being normally biased to its rearward position, as by means of a tension spring '15, while this lever is moved to its forward position by means of a rod 15 connected to and forming a part of an armature H of a polarized relay 18, which relay is of the type commonly employed in pay station telephones to be operated by reverse current flowing through the telephone line when a call has been answered. The armature I1. is illustrated as being pivot-ed at 19 so that energization of the relay 18 will cause a downward movement of the armature 11, a right hand movement of the rod 16 es viewed in Figures 3 and 5.

By referring, particularly, to Figures 3 and 5, it will be observed that the local collection chute 34 is provided with a refund opening'or slot V a in the side wall thereof, this slot. extending ime mediately adjacent. and somewhat above the level of the pin 61 8011311311? a coin descending through the chute 34 striking upon the fpinfi'l,

will be deflected sideways through the slot 88 a and into the refund chamber 35 to be passed to the refund receptacle 32. J r

The remaining. apparatus disclosed and the operation of that herein described, will best be understood with reference to assumed-operationof the telephone system.

Assuming the telephone station to be in nore mal condition, that is, with the receiver uponits hook I and with current on the,- line ready for completing the callsfor service; a person desire ing to use the telephone may do so by lifting the receiver 6 from its hook and thereafter depositing a coin in the 5 or nickel opening ll in the coin guide l4. I

It is assumed that the switch 54 is so connected in the line circuit of the telephone system that unless this switch is actuated from its normal position, as is illustrated in Figures 3, 4 and 5., the telephone will be ineffective to complete a call. This type of connection is commonly employed in telephone structures at the present time, and will be understood by those skilledin the art. In our copending application, Serial Number 508,952, hereinbefore referred to, one method of permitting calls to be completed only after the deposit of the coin, was illustrated.

Upon lifting the receiver from the hook I the inner end l2 of the hook was removed outof effective engagement with the lever 42, thus permitting the rod 39 to move forwardly and thereby permitting the rod 48 to be rotated to such position as to remove the pin 53 from the path of the coin descending through the chute 25.

It will be observed, however, that at this-time the transfer basket 2! will be in its rearward position, even though the pin 45 has been withdrawn. The transfer basket 2! is held in the rearward position by means of the engagement of the lock or latch pin 54 engaging the forward 7 side of the transfer basket 2|. Thus the transfer basket aligns the opening 26 therethrough with the upper end of the local collection chute 34. The coin descending into the local collection chute 34 passes downwardly as is indicated at 52 and strikes the inner end of the lever 60, rotating this lever to perform two functions, first, to open the contacts of the switch 64, and, second, to rotate the shaft 59 to depress the lever 55.

The opening of the contacts to the-switch 64 renders the telephone station active to complete a call, for example, as by means of the connec-. tions illustrated in our copending application, Serial Number 503,952, rendering the dial-8 effective to select a called station when the switch contacts 64 are opened. The operation of the lever 55 withdraws the latch pin 54 from the transfer basket M and permits this basket to fall to its forward position under the influence of gravity. It will also be observed that as the rod 48 was rotated to its forward position, the depending pin ll therethrough was moved forwardly to permit the lever 69 to also move forwardly under the influence of spring 69a to 'po sition the pin 55 in an obstructing position in the local collection chute 34 so that after the coin 52 has passed the lever 60 it descends andis held upon the pin 65. The patron may then dial the desired number of the station to which he wishes connection.

If the selected stationdoes not answer, the

patron may restore the receiver 6 to its hook I and the coin 62 will be immediately refunded. This result is accomplished by reason of the fact that when the receiver 6 is restored to its hook I, the inner end of the receiver hook will move the rod 39 to its rearward position, thus rotating the rod 48 to its rearward position so that the pin thereon engages and moves the lever 69 to such position as to remove the pin 65 from obstructing position in the chute 34 and the coin 62 will thereafter fall downwardly in the chute 34. During all of this operation the pin 61 mounted upon the lever 13 stands in its inward or obstructing position in the slot 34 so that as the coin released by the pin 65 descends until it strikes upon the pin 61 it is deflected through the slot 80 into the refund chamber 30 and thus will pass to the refund receptacle 32.

However, assuming that the called station answers, such response will supply current to the telephone station of proper polarity to operate the reverse current relay 18. The operation of reverse current rely 18 will draw its armature I1 downwardly, moving its pin or rod 16 forwardly to engage and move the lever I3 to its forward position, thus-removing the pin 61 from the local collection chute 34. It will be observed that the upper end 14 of the lever 13 engages the lever 69 so that when the lever 13 is moved forwardly the lever 69 is moved rearwardly to remove the pin 65 from obstructing position in the chute 34. Thus, as soon as the called station answers, the coin 62, which up to this time had been held upon the pin 65, will be released and will pass downwardly in the chute 34 past the pin 61 and will thus be passed through an opening 8| formed in the partition shelf 82, the opening 8| being aligned with the lower end of the chute 34. Immediately beneath the shelf 82 is a coin collecting receptacle 83 having an opening 84 therein aligned with the opening 8| sothat the coin passes to the interior of the collection receptacle 83.

It will be observed that collection of the coin takes place only if the desired connection is obtained, while the coin is refunded if, for any reason, such connection is not obtainable.

. It will be observed that the left hand end of the rod 48 (see Fig. 4), is provided with a pin or wire 85 bent into such configuration that when the rod 48 is in its rearward position, as when the receiver 6 is upon its hook I, the Wire 85 will be moved into engagement with the coin actuated lever 60 and positively move the same to its normal position, as is illustrated in Figures 3, 4 and 5, ready for a subsequent operation of the telephone station.

It will thus be observed that allcalls'for local service require the deposit of the coin before connection can be obtained, and that all such coins are directed into the local collection chute 34-to becollected or refunded, depending upon whether or not the service is obtained.

' It will also be observed that in the event that the person using. the station should inadvertently deposit coins in the dime or quarter openings l6 and 5, the fact that the transfer basket 2| is retained in its rearward position will cause these coins to pass immediately to the refund chute 29 to be immediately refunded, thus, even though the station is used improperly, the patrons erroneously deposited coin will be returned. Also, as hereinbefore stated, shouldthe patron deposit the coin in the 5 chute prior to lifting the receiver, such coin would not be collected but would be held in abeyance by the pin 53until the receiver is lifted and will then pass to the local collection chute 34 to bring about the desired connection for local service.

Our telephone station is also adapted for the completion of long distance calls and for collecting the necessary toll for such calls, such collection being made through the coin maze comprising chutes 36, 31 and 38.

As hereinbefore stated, the entrance openings of the chutes 36, 31 and 38 are so located as to be aligned with the openings 24, 25 and 26 in the transfer basket 2|, when the transfer basket 2| is 'in its forward position. Therefore, upon initiating a long distance call, the patron will be required to deposit a coin in order to obtain connection to the long distance operator.

As is usually the practice, the coin required is the lowest denomination coin for which the station is adapted, namely, the nickel or 5 coin. Thus the patron desiring a long distance call will lift the receiver 6 and deposit a coin in the opening H, as for making the local call. The coin so deposited will pass downwardly to operate the coin actuated lever 68, actuating the switch 84 to render the station effective to call the long distance operator, the coin coming to rest upon the pin 65 where it will be held in abeyance until the long distance operator responds.

The long distance operator, upon being notified of the desired station to be called, may then either advise the patron to hold the line or to hang up the receiver until the connection is obtained. If advised to hang up the receiver, the initial coin employed to obtain the connection with the long distance operator, will be immediately refunded as soon as the receiver is restored. This operation has previously been described as being accomplished by the rotation of the rod 48 when the receiver is placed upon its hook 1, since the movement of the rod 48 will engage the pin H with the lever 69 and remove the obstructing pin 65 from the local collection chute in which the coin has been held in abeyance; It will be observed that the response of the long distance operator will not actuate the reverse current relay 18 since it is the usual practice to employ such connections as will permit the long distance operator to obtain connection with the calling station without reversing the line current thereto; On the other hand, if the long distance operator informs the patron to hold the line, the 5 coin employed initially to obtain the connection with the long distance operator will be held in abeyance by the pin 65 until the completion of the long distance call.

Assuming that the patron was informed to hold the line, the long distance operator, upon obtaining the connection desired, will notify the patron of the amount of the toll necessary for the call, which may be deposited as required in the openings l5, |6'and H in the usual manner. However, the deposit of the initial coin'required to obtain connection with the long distance operator actuated the coin actuated lever 66 to remove the latch pin 54 from the transfer basket 2|, permitting this basket to fall into its forward position so that upon the subsequent deposit of coins for the long distance toll, these coins will pass immediately into the respective chutes 36, 31 and 38, constituting the coin maze. The chutes 36, 31 and 38 may be provided with the usual signal bell 86 and 81, respectively, so that an audible signal is produced to inform the long distance'operator that the desired toll has been provided deposited. The chutes36, 31 and 38, herein illustrated, are identicalwith those in common use in telephone systems at the present time, and further description thereof is not deemed necessary.

When the call has been completed and the patron restores the receiver to the hook I, such restoration will immediately refund the initial nickel which was employed to obtain connection with the long distance operator, this operation being identical with that previously described in connection with the restoration of the receiver on the hook when the local call was not obtainable.

On the other hand, if the patron has been informed to restore the receiver 6 to its hook I to await further response on the part of the long distance operator, the long distance operator, when the connection has been obtained, will call back the station. In doing so, the operator will place reverse current upon the line so as to operate reverse current relay 18. The operation of reverse current relay 18 at this time will remove the pins 65 and 6'! from the local collection chute 34 but the coin which had been initially deposited therein will have already been refunded so that this operation produces no undesirable effect.

However, it will be observed that the upper end '54 of the lever 13 has attached thereto a wire 88 which extends immediately below the coin actuated lever 60 sothat upon operation of thereverse current relay 18 this wire 88 will move the coin actuated lever 60 exactly as though a coin had operated it. In other words, the operation of the reverse current relay #8, by the long distance' operator, will open switch contacts 61 and will also remove the latch pin 54 from the transfer basket 2|, allowing the transfer basket to move to its forward position ready for the collection of long distance toll. Hence the patron, upon being informed of the toll charges, may deposit the necessary coins in openings I5, Iii-and H, which coins will immediately pass to the long distance collection chutes 36, 31 and 38, whence they will pass immediately through a second opening 89- in the partition shelf 82 and thence into the collection receptacle 83.

If desired, the collection receptacle may be with a partition 90 to segregate local collections passing through the slot .81 from long distance collections passing through the slot 89 so that an accurate accounting for either long distance or local collection-s may be readily made.

. .Thus it will be observed that in the obtaining of long distance calls immediate collection of the toll is obtainable, thus avoiding any possibility of erroneous refund of long'distance collections.

From the foregoing, itwill be apparent that we have provided a pay telephone station in which a single housing is employed tor the purpose of collecting either local-toll or long distance toll, and in which collections are dependent upon obtaining the desired service, while .refunds are made immediately upon the failure to obtain the desired connection. Moreover, coins erroneously deposited will be immediately refunded.
