Y UNITED STATES PATENT OFFICE Tron or DELAWARE 1 V raysra'mon' Application meanareh s,

Th present invention relates in general to inultiwcoin paystation devices designed for usein conjunction with and as a partof the substation equipment of a subscribersline in an automatic telephone system. More specifically, the invention is concerned with the provision of a unitary multhcom paystation device in which the deposit of acoin need not he made until the subscriber called responds, or, in the caseof a toll connection,

untilthetoH operator has obtained a desired x party and requested the calling subscriber to necessary to pay for where many toll calls are initiated, it is quite advantageous to provide means wherehy coins can also he collected to pay for such connections. Thisneed has heretofore been met, after a fashiolnhy increasing thesize of the base upon which the pa-ystation shown in theMadsen patentwas formerly mounted,

and mounting thereon sucha paystation together H ll a multifcom recelvjlng box containing only coin aetuatedlsignal devices, such, for instance, as those usedinthe paystation apparatus disclosedin the Forsber r \Vithsuch an arrangement localcalls are extended as formerly; i. e., by the deposit of acoinin the single slot device upon the response of the called subscriber. It a toll call is set up. the operator. instructs the subscriber. to deposit the required coinorcoins in the multi-eoin device and supervises the deposit of the coins by listening to the coin actuated signals asis done in supervising the deposit of coins in a pay station such as shown inthe previously mentionedForsberg and Long patents.

Since in the present invention no coincollect or refund operations are necessary, alla-pparatus of this character is omitted, but the downwardly projectingextem sion, of thearmature of the polarized magnet, formerly used for these operations, is

used instead for controlling the operation of an additional set of contactsprings similar to those actuated bythe polarized magnet disclosed in the Madsen patent.

The invention is disclosed in two sheets of "drawings, comprising Figs. 1 to .5, inclusive. a: Fig. l is a front vew of the device, in eleva tion; Fig.2 diagrammaticallyillustrates the circuits andapparatus; Fig. 3 is a frontview, in elevation of the electro-magnetic part of the mechanism 'in normalposit'ion; Fig. 4; is

a rear View of Fig. 3 in elevation with cer tain parts omitted forsake of clearness and with the various parts shown in operated position; while Fig. 5 is a View of a portion of Fig. has seen from the left. It also shows a section of a portion of an associated coin chute. i

Referring now to Figs. 2-5, inclusive, a detailed description will be givenof the polarized magnet and its associated parts, after ing arm 12, shown in Figs. 2 and 3 and an arm 12 shown in Figs. 2, 4 and 5, to which is secured an extension 11 pivotally support- I ing a spring actuating arm 13.

The free end of arm 13 1s supported bya small bracket 18 secured to a doubl'earm lever 26, which is also pivotally secured to upwardly extending portionsof the previously mentioned plate 23. The lever 26 functions in substantially the same manner I as does the lever 113 of the Forsberg patent previously referred to. The arm 27 of the lever 26 is moved into the position in which it is shown in Figs. 3 and 5 by the bushing on extension 12' of the armature plate 12. And although a tension spring 32 tends to movethe arm 27 and close contact springs 29, upon movement of the armature 11 to its reverse position, the

movement of arm 27 is prevented by the coin trip lever 30. The deposit of acoin in the coin chute, however, will cause the lever30 to momentarily swingout of the path of movement of arm 31 and permit the tension spring 32 to rotate the lever 26 to cause its arm 27 .to close contact springs 29.

The actuation of the-armature 11 to'its'alternate position causes the springs 19 to be closed by armature extension 12; causes the arm 11 to move the spring actuating arm 13 to the right, as viewed in Figs. 2 and 3 and with it the tension of spring 33into the position in which it is shown in Fig. '4. The movement of the spring 33 away from the bushing on spring 16 permits the tension of spring 16 to become effective to bring this spring and the associated springs 14 and 15 into contact with each-other. When a deposited coin actuates lever 30 and. causes the lever 26 to be rotated in the manner previously mentioned, not only are the contacts 29 closed, but also the free end of lever 13 is slightly elevated by rotation of the bracket lever 26 sufficiently to causethe bracket 18 to move the arm 13 clear of the top of spring 33. Spring 33, therefore, again becomes effective to overcome the tension of spring 16.

This results in the springs 14, 15 and 16 again being separated.

I If now the armature is restored to itsinitial position, as shown in Figs. 1, 2, 3 and 5,

the bushing on extension 12' of the armature plate 12 will rotate the lever 26 clockwise; the

arm 27 will again force the tension spring away from contact springs 29, permitting them to open the short circuit around winding 24; lever 18 will be again lowered permitting arm 13 to again drop behind spring 33; and the arm 27 will be elevated sufficiently to permit coin actuated arm 30 to restore, by gravity, to its normal position.

In view of the foregoing description and of the disclosures in the patents hereinbefore referred to, it is believed that the invention can be most readily made clear by describing its mode of operation in a typical installation. I v g Referring now to Fig.2, it will be assumed that the subscriber at substation A desires to set up aconnection to some other local subscriber .of the system. Upon the removal of thereceiver 20.:at substation A, a circuit is closed, over which current from the exchange battery (which is normally bridged across the- line conductors 1 and 2, in series with the line relay associated with the calling line) flows as follows from the-exchange over line conductor 1 on the right of the consprings 8, impulse springs 7 of the calling dei vice CD,transmitter 9, primary winding of induction coil 22to line conductor 2, and thence to the exchange. As a result of the closure of this circuit the calling line conductors 1 and'2'are extended to the line relay of an idle selector or connector switch, depending upon the capacity of the 1 system. The removal of the receiver also closes the receiver circuit, which is a local circuit including the switch hook 2 1, the receiver 20, transmitter 9,'impulse springs 7, springs 8, the winding 24 of the polarized relay, the condenser 6, and the secondary winding of the induction coil 22.

Although the winding 24 of the polarized magnet is'included in the above-described circuits, this magnet is not energized at this time due to the normal current flow being in the wrong direction.

' The calling subscriber may now proceed to manipulate the dial of his calling device CD in accordance with the digits of the number "of the substation desired, whereby the automatic switches used in extending the connection are operated in any well known man-' ner to complete the desired connection. During the operation of the calling device the shuntsprings '10 are closed to short circuit the receiver and transmitter. This is the usual provision made to reduce the resistance andimpedance of the line circuit during the transmission of impulses, and to preventnoises in the receiver during the dialling operation. 4

' When the called subscriber responds to the thelsreceiver 20. The shortcircuiting of the call, thevback-bridgerelay of the connector usedin seizing the called line responds and reverses the line conductors 1 and 12 as regards their battery connections. Current now flows over thexline circuit :and: through the winding 24 0i the polarized malgnetinthe rent in winding 24 of vthe polarized magnet 1 causes it "to rotate its armature 'in a clockwise direction, that is, toward the core of: coil 24. When the armature is attracted in this direction it carries the arm 13 to therig-ht,

permitting the springs 14, 15, and 16 to come into engagement. The armature itself,

16'short circuits the transmitter 9, and connectsthe resistance 17 in a shunt circuit across transmitter makes 1 it impossible for the calling subscriber to talk to the called subscriber through the medium thereof, whilethe resist- -ance 17 prevents 'thesubscriber using the re- :ceiver as a transmitter, but does notprevent '1 the callinghubscriber from hearing the to again separate. "place a direct short circuit around the Windcalled subscriber answer. p U When the calling "subscriber hears the -called subscriber answer, he depositsa coin in the coin chute. The Weightof the coin strikinglever 3O causes thislever to release the' arm 27 of lever 26, which, under thetension ofspring 32 now closes springs 29 and raises arm 13 abovethe top of the tension spring 33, thereby allowingsprings 14:,1'5 and 16 Springs 29 in closing ing 245 so as to exclude it from the talking circuit. The separatingof the 'sprifngs, .14,

is-and 16 leaves the talking circuit for the calling substation innorrnal condition, and

the two subscribers ihay converse oven the circuit s represented bythe heavily drawn lines.

After the conversation is completed, the.

calling and called subscribers replace their receivers.

It will be recalled that'when the called subscriber responded the operation of armature 11 of the polarized relay resulted inthe" 610- coins as sure of springs 19. The closure of these springs completed a circuit extending from "line conductor 1 at the of condenser 6, throughsprings 19, winding 25 of thefpolarized magnet, the impulsesprings transductioncoi122 tothe line conductor 2. This circuit is for restoring the paystation appara- ,tus, to normal, and it is not effective ,while p the receiver is oil the hook at thestaticnjAras winding 25 is short circuited by a cit-cut extending from the lower terminal of winding 25, through thespringslQ- and: 29, and the closed switch hook springs 8, back to the upper terminal of winding .25. i v a When the calling subscriber. replaces his receiver, this short circuit is removed at switchhook springs =8, leaving the winding 25 in bridge of the line conductors l and 2. reversed direction. This'reversal of theicur- If the called subscriber has not as yetreplaced his receiver, upon the switchehook, nothing further happens at the exchange, as

"the current flow is still in the direction appropriate for rotating armature 11 clockwise. However, as soon as the called subscribers receiver is replaced upon theswitch hook the direction of currentflow over conductors l 311(12 and through the winding 25 is restored 'movement oflever 26 to its initial position permits lever 30 to restore by gravity to its initial position, to again lock, the lever 26 independent of thearmature 11 and to permit the lever 13 to again drop back of the tension spring 33. The openingof springs 19 interrupts the bridge formerly extended across line conductors 1 and 2-and including the winding 25, permitting the central ex 1 change apparatus to restore tonormal in the usual and well known manner. 1 Vwien the subscriber at substation A desires to make a toll call the connection is set up in the some manner as for alocal call, butthe switches which extend a connection to an operatordo not reverse the direction of current flow to the calling line, consequently the polarized apparatus is not operated and the calling subscriber is therefore not required .to 1 deposit a coin to converse with the toll operator.

Since the paystation device is equipped with openings for receiving difierent sized coins and with signalling devicesfactuated bythe deposit of coins, the toll operator at any time she desires may request that the calling subscriber deposit the appropriate cointo pay forthe connection, the operator being informed of "the amount deposited by theusual laudible signals produced by the they passonidown into the collection boxr" i 1 What is claimed is: i
