YianefrsfrEarlier SYSTEM. l

yTo all whomw may concerti/.Q V 'Be it known that L'EDGAR CLARK, a citizen of the United States,`residingv at Richmond 'HilL in the county of'Queens, State of New York, have invented certain new and useful Improvementsin Registering Systems, of which the `following is a' full, clear, concise, and exact 1description.

This invention relates to automatic telephone exchangesystems, and moreparti ulaily to Ysystems .employing .automatic switches, in which such switches 'are controlled by means of a sender located at a central oilice. Y

Itis' the object'of this invention to pro vide an improved .means for transferring .registrations from one register Eto another. A featureof. the; invention is the use of a plurality of'multiple contact relays arranged on a coordinate basis. These relays are energized under the control of a primary registering device'and are utilized in transferring a registration from such primary. registering device tolsoine other 'registering device.

V'in systems of the typeshown inlatent No. 1,395,977, issuedNoveinber 1, 1921, to F. A. Stearn'and'F. iJvfScudder, a 'set of registers is positioned under the control of anV impulse sending device in accordance with the position 'assumed by a :multiposition switch, termed in such application atranslator switch. n

1t is more particularly the object of'this invention to'eliininate the necessity' of using an impulse generating device'to position a set of registers under the control of primary registering devices.

it is a further obJect ofthe invention to provide a system in which `a transfer of registration may be accomplished ata very high rate of speed.

An 'additional is an arrangementsuch that all parts rof the registration are transferred simultaneously.

ri. further feature ris an arrangement 'whereby 'the senders of the exchange are divided into groups, there being a set of transfer relays common to Aeach `:group ofl senders. interference between the send:

ers' ofany one vgroup 'is prevented by i'niils' of au alie weer switch.

,)tlier features of the 'inntion result er s which'a connection 'maybe extended to a feature of the inventionV from". the 'arrangement of the: circuits'wh'ich Acontrol the lsetting of the registers and will "be xclearly, apparent from the' detailed description which follows. Thev invention has been shown applied to a full automatic system of the7 type lshown .in the above men- 'tionedfPatent No.'1,395,977.

l s The invention is, however, obviously capableof a Vwide lrange"of-usage, andiis therefore' not to'be limited to 'thespecific embodimentl shown.

Ageneral 'description of the isystem will first bei given 'in order 'that the detailed description which follows' may be `more 'readily understood. l s s The jgeneral operation Vf the system is substantially similar to that described in the abovementioned "patent to F., A.' Stearn "'airdurvF. "JJScudder, No. 1,395,977; Whein the calling subscribe-r removes his receiver from the switc'hhoo-k, *a line swit'ch'is ,i put into o'pe'rationfi to selecta' trunk lleading to lan idle district selector. The seizureof such trunk 'puts into operationafsenderlselector "whichn`l associates "an idle Ysender with the Selected' trunk ciifcuit.` EachV sender is"pro 4vided "wi'th' a yl'ilurality ofA v ste-fp^by:'step j primary registering devices. These 'registering "devices 'may of any desired char- 'acta but me preferably' er 'the type shown 'and described 11,1 "raient No. 1,4725e65, fis

sued October 30, 1923, to O. F. Forsberg and R. M. De Vignier. A progression controlling switch is utilized to direct the successive series of impulses to the proper registering devices. Assuming that the system is to serve a` large exchange area, it may well be that live hundred oflices will have to be served. Byv utilizing the first three registers to record the office designation, one thousand oitlice combinations may be obtai-ned. In the present disclosure it will be assumed that each of the first three registers has only eight effective registering positions, thus providing for a total capacity of five hundred and twelve offices.

All of the senders of the exchanges are divided into groups. A set of multi-contact relays is associated with each group of senders, as is an allotter switch. The multicontact relays may be of any desired mechanical construction, but are preferably of the type shown and described in an application, Serial No. 482,106, filed July 2, 1921, in the name of O. F. Forsberg.

It will be assumed that in order to obtain connection to a desired office, the calling subscriber' must dial three times. rlhree primary step-by-step registering devices are therefore provided to receive these series of impulses. The register which receives the first series of impulses will be hereinafter referred to asV the A register, the register which receives the second series of impulses will be referred to as the B register, and the register which receives the third series of impulses will be referred to as the C register. Associated with the C register of each sender are eight multifcontact relays. Each of these relays is provided with Gat contacts. It will be assumed that the C register has eight effective positions. A different one of the multi-contact relays just referred to will be actuated in each of the effective positions of the C register.

Eight multi-contact relays are associated with each B register. These multi-contact relays each have eight contacts, thus providing 641 outlets. A different one of these eight relays is operated in each effective position of the B register. It will thus be obvious that by suitably coordinating the A, B and C registers and their associated relays, potential supplied to the wiper ofthe A register may be directed to any one of 512 outlets. A choice of eight outlets is provided at the A register. These eight outlets are multipled to the common cross wires of the eight relays associated with the B register. In accordance with which one of the relays associated With the B register is energized, any one of 64 outlets may be supplied With potential. These 64 outlets are multipled to the eight relays associated with the C register, and, in accordance with which .one of these relays is energized potential may be supplied to any one of 512 out-lets.

There is associated with each group of senders, a multi-contact relay organization comprising 512 relays, each having twenty contacts. After the primary step-by-step registers have been positioned, potential is supplied to the desired outlet selected by the primary registers of the sender under the control of an allotter which prevents interference between senders of the same group. One of the 512 control relays is thereupon energized and places the proper combination of potentials on the cross wires of the. transfer relay frame.

There is provided for each sender a relay having twenty contacts. Each of these relays controls contacts which cooperate with common multiple cross wires which have been provided with a suitable combination of potentials under the control of the registers. Upon the energization of the multi-contact relay which is individual to a particular sender, the desired combination of potentials is placed on nineteen conductors extending to the register relays of l? ig. 3, which are individual to the corresponding sender. These relays, upon energization, are locked up and then utilized to control the selective operations of the switches which establish the connection in a well known manner.

Summing up, the organization is such that by means of a set of primary registering devices comprising A, B and (l registers and their cooperating relays, one of 512 relays which are common to the senders of a group is energized under the control of an allotter. The particular one oi' 512 relays energized places potential on the particular ones of the cross `wires which will accomplish the energization of the desired ones of the register relays of Fig. 3. After the registration is placed on the common cross wires of the transfer relay structure, the registration is directed to the register' relays of the particular sender then allotted by means of a relay individual to such sender. It is obvious that by combinations of the nineteen register relays of Fig. 3, more than 512 office designations may be recorded so that it will not be necessary to use all possible combinations of the register relays. lt is also obvious that by changing the combination of potentials controlled by any one of the 512 relays w iich function in connection with the transfer frame that the change in routing thus accomplished will be automatically effective on all the senders of a group. lf the terminals of the corresponding register relays of all groups are multipled and brought to a distributing frame, it is obvious that a change of routing may be accomplished by simply changing connections at such distributing frame and that such change will then be effective on all the send- Cil Way of common Vcross coi'ii'iections' which is incident to the usego'tl satrzi'ns'lator switch is thus retained inftlie present system. It is believed that the operation ofthe system 'receiver fromthe lswitc'hhook, causing the operatioiiiot the lineLsWi-tch 2-t`o connect the substation line to a trunk leading on to an idle district'selector. AThe seizure fof such trunk causes theoperation of a sender selector, generally indicated at which causes an idlesenderfto be-associated with the trunk' v'circuit which has been Itaken for use. The operation of the line switch 2 and the sender selector 3 are' Well known, and yit is believed that their operationwi'll vbefunderstood Without ti'iitl'i'e'r description. The previouslymentioned Patent, No. 1,395,977, shows suitable circuits for accomplishing this operation;-

Test relay loris energized and opens the'circuit of'step'ping magnet 17, thusbringing the allotterA to rest. The continued' deen'- ergization ot steppinginagnet 17 allows' slow release `magnet 1S to deenergize and complete a circuitfrom ground, through its armature and back contact,` right-hand armature and frontcontact of relay16, allotter brush 20 and itsfsecond Contact, conductor 21, Winding of relay 22, to .grounded battery. Relay 22 is energized, and lat'its lefthand 'armature-completes a circuit to cause the energization ot Vrelay 13,' which locks Ito ground rat C register brush 14.

It Will Y be Leiass'uinedthat i i the A registeris in position 3, the B register in position 2, and the C register in position 2. The energization of relay 22, therefore, coii'ipletes a circuit from grounded battery, winding ot relay 23, outer right-hand armature and 'front contact ot relay 22, A register brush 2li, and its third Contact, conductor 25, and thence to the grid wire 26 ot' the relay structure associated with the B register. fit the same time, a circuit is completed 'from grounded battery, winding ot' relay 23, middle right-hand armature and 'trent contact of relay 22, B register brush 2T and its second contact, conductor 23, winding oi" relay magnet 29, to ground. Magnet 29 is energized and extends battery supply trom grid wire 26 to conductor 30. lt is to be understood that there are eight grid wires common to the eight relays corresponding to relay 29. For the salte ol simplifying the disclosure, they have not all been shown.

The energization ot relay 22 also ceinpletes a circuit trom grounded battery, winding of relay 23, inner right-hand armature and front contact ot' relay 22, C register brush 3l and its second contact, conductor 32, winding ot relay magnet 33, to ground. Relay 33 is energized and connects its armatures to the common grid wires which are associated with the A register relays. 1t is to be understood that there are 64 of these common grid. wires, a portion only of these wires being` shown to avoid needless extension ol the drawing-f1. The energization ot' relay 33 extends conductor 30 to conductor by way of grid wire 36. The battery potential supplied to conductor 35 causes the energization of relay magnet 37, which is energized, and supplies battery potential to desired ones ot the cross wires which constitute the grid ot the transfer relay structure. lt is obvious that the relay magnet 37 has been selected out ot the 512 similar magnets as a result ot the coordination ot' the A, B and C registers and their associated multi-contact relays. lt is also obvious that no other relays corresponding to 37 can be energized at this time since` they can only be energized under the control of a relay corresponding to relay 22. Since relay 22 is energized undei the control ot an allotter, it is obvious that even though the senders which are indicated by the dotted rectangles to the lett oi Figs. l and 2 have their registers positioned, snch positioning is without eiect on the transter structure since the allotter can assign only one sender at a time. 1t is to be observed that the circuits just described, which were completed through the winding ot relay 23, cause the energization of this relay. rEhe energization of this relay causes the energization oi relay magnet 38 over an obvious circuit. Relay 38 is the magnet individual to the sender under allotment and the energization of this relay causes the registration set up on. the grid wires to be transferred to the register relays of Fig. 3.

1t is believed that the method of transferring the registration to the register relays ot Fig. 3 will readily be understood. rl`he energization et' relay magnet 37 places battery potential on the common grid wires 39, e0, all, 42', 43, lil and l5. and tl e energization of relay magnet 38, which is individual to the particular sender under allotment, causes this battery potential to be supplied to conductors 4-6, 47, 48, yl-), 50,51. and 52, respectively. 1t is to be understood that each ot the conductors numl ed from 46 to 52, inclusive, is permanently connected to the right-hand winding et one of the register relays of Fig. 3. 'lliere are as many 01"' these conductors as there are register relays in F ig. 3. All of the conductors have not been shown in order to avoid needless duplication. The actual connection from the conductors to the relays is not shown. since it is believed that the arrangement oi this part of the system may readily be imderstood without showing the actual conductors. The conductors have been shown as terminating in the cable 53 which is tanned out tothe various rows of relays atl

points

54, 55, 56, 57 and 53. Nineteen register relays have been shown in l? ig. 3 and it will therefore be assumed that lt? conductors extend to the contacts of inagnct 33 and that these 19 contacts are selectively supplied with potential by means of the ll grid wires corresponding to wires 39 to 45, inclusive, which are in turn selectively supplied with potential in accordance with which one ot the magnets corresponding to magnet 3?' which is energized. By selectively' supplying potential to the set ot 19 conductors oif which conductors 46 to 52 are a part, the 19 register relays ot' Fig. 3 are selectively energized by means of a circuit from battery to ground through their right-hand windings. These relays upon energization locl; up through their' right-hand windings. The locking battery supply is not shown, but it is supplied in the same manner as itis supplied in the previously mentioned Patent No. 1,395,977. l; should be observed that 'he register relays of F ig. 3 correspond exactly and bear the same numerical designation as the register rela-ys of Fig. l0 of the patent `instV mentioned. The contro-lling leads by means ot which these relays cont-rol the selective operations oit the district; and oltice switches and also by means of which they control the determination of the class of call, are identical with those shown in the above patent. 1t is therefore believed that no further description is needed as tov the method in which these register relays control counting relays to govern the switches indicated in Fig. l, since a complete descrption of anv identioalioperatong occurs*` in thepatent.v Y

While this registration is vheingz-transferred yto -thevrelays-or`-Fig 3, the calling. subscriber has been! send-ing `lin `series of imf pulses in; accordance WithA the numerical designation of the Wanted line. Thesefim-r pulses arereceived on registers as described.y in the mentioned Patent No. 1,395,977 and-K are later utilized to control incoming and inal :selector switches or else to `control a cally indicator at the operators-postiom Since this part of .the operation of vthezsys-VV temi -isin everyv Way similar to that .shown and :deseriloed in suolipatent,` it is believed that description of this part of ythe opera.- tion isv unnecessary in-tlie.present applica-v4 tion.

It should-beobservedlthat the energiza:

tiony of relay magnetlSS: selectivelywsupplies The allotter savitch,l Iadvances :itsfW-ipers one v step, thus causing the release of relays 22 and 12.-.` The circuit oit-relay 22 is;,opened. by the movement. .of yallotter:hrush 20. The release of vrelay y22, 'causes thefdeenergization oi relay 23 which allow-s relaymagnetvl to4` he deenergized. Deenergi-zationot lrela-y 22 also causes the release of relaymagnets 29- and' 38. as Well as relay; magnet 37,

It should be .xnoted that relay' 22. upon feuergi'zation causes 1 the energization of relay 13 which locked upto .ground at an ott' 'non mal contact served-by C register lloiaislrll.

The energization of -relay.13iholdsopen theoriginal yenergizing circuit vof relay 12 to prevent thereenergiz ationy or continued fen ergization of Vrelayl?, and thus `prevents the` allotter from allotti1igthesame sender.

After the sender has advanced ioneistep, it remains in this positionr until .some other sender is .to loe allotted.` If there has .heenA a sender Waiting lallotment-the energization of the relay correspondings to ,relayff 12Vat.
