" i f PRINTING-TELEGRAPH SYSTEM.

. Application led -December Taall whom t may;concerti# 4Be it'known that I, PAUL RAINEY, a citizen of the vUnite States, residing 'at Glen Ridge, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Printing- Telegraph Systems, of which thefollowing is a full, clear, c`ncis`e,l'and exact description. p

Thls invention relates to printing tele graph systems, and particularly to switchmg lmechanism whereby the operation of systems `in whichu'a plurality of sets of printing' telegraph Iapparatus located at one stationLA .may be facilitated.

f .An object'ofthe..invention is to provide in a printing telegraph system having a t .ated independently of the correspondingv .plurality .offset-sof printing telegraph api l paratus vlocated at one station, switching means whereliyjtlie transmitting and receiving mechanismsoi -each set may be opermechanisms of the other set.

- Another object is the provision in ,a vsys-S.

tem of 'the above character of vswitching means whereby the'transmittlngA mechanlsm oflone'set and-the recelvlng mechanism of the other set may beoperated.

Another object lis to provide in a print- :.ingtelegraph system having a plurality of sets of printing telegraph apparatus located A at one station, switching means wherebyv the recorder of one set may be operatedin conjunction witl the other set.

It is customary practice in ofiices provided with printing telegraph apparatus to have spare or duplicate sets to insure continued service of the system, should one of the sets fail.. Each setis equippedv with transmitting and receiving distributors` automatic or keyboard transmitters, and rev ceiving printers, all ofwhich are mounted on separate tables which accoinmodatebut a single operator at a time, and conse-A quently do not permitl lthe simultaneous observance of the operation of the transmitti'ng and receiving mechanisms by sepa'- rate operators. To obvia-teisuch'conditions, the present invention provides, in a printing telegraph system comprising two operating tables, each equipped with complete transmitting and receiving mechanisms located at the statica and. connected by a line con,-

1 the receiving distributor ofv so, 1'921.. serial No. 525,957.

` ductor vlequipped for duplex operation, switching mea-ns whereby the'equipment `of each table 'may be operated in various combinations. Forfexample, the transmitter and transmitting distributor of one set and the receiving mechanism and receiving distributor of the other set may be operated together, the receiving printer individual -to i onetable may' under different conditions bev controlledby the receiving distributor of theother table, or the equipment'of cachot the tables may be operated independently. Infthe drawing, there is shown a -lineconductorf provided #for d upleX .service extending to a distant station where apparatus similar to that shown in the drawing is located. .Attached to the line G--are distributors connect the transmitting mechanism with the line,- while the latter conneet the recording mechanism thereto. The

distributors 7 and 9 toget-her With their A, While the'other distributors'S and 10 form a second set B, each of 'which may be operated separately, tributor of one set tributor' of another ing I printer operated, printerof eitherset maybe i'operated in conjunction Withthe receiving distributor of the other set.. l

and the receiving discurrent control means 11 which, in the pre! ferred form of thein'vention is a tape transmitter, though. obviously, a 'keyboard transtransmitting 'distributors 7 andl 8 and re-f ceiving distributors 9 and 10. The former associated mechanisms form a complete set s" the transmitting disset with. its correspond` or the receiving The transmitting apparatus comprises i mitter may -be'su'bstituted in its place. The

transmitter 11 includesafseries of contacts 12, 13, 14, 15 iandl which are arranged to be selectively actuated -by selectively operated inembe rs controlled by perfor-'ations in the transmitting tape (not shown). `In or beadder that the transmitting tape may vanced to bring the next succeeding groupv of perforations in alinement with the contact's`j12 to 16 inclusive, an electroniagnet :17 is arranged to be operated upon' each revolution of the vbrush arm. of the transmitting distributor 7 for accomplishing this'v result, as will be more 4clearly described hereinafter. -Associa-ted with the contacts 12 to 16 inlusive,is a. plural'ty of signal stor-` ing relays 18., `19. 20, 2l and 22 which are -the local segments 52, 53 and54.

provided for storing the inipul'ses in accordance with the operation of the selected contacts. Each Iof these relays has two windings, one of which serves to initially energize the relay while the other serves to inaintain'the relay energized after their contacts have been closed. Each relay is also provided with two armatures, one forA extending circuits tothe segments of the transmitting distributor 7 .and theA other serving to'coniplete locking circuits there- The recording mechanism 23 provides a series of selectingniagnets 24, 25, 26, 27 and 28 which have the'Lr windings connected with the various segments forming a part of the outerringof tlie`receiving distributor 9. Thus, the windings of these magnets will be successivelyconnected-'uponthe release of the brush arm 29 due to the energization of the release magnet 34 lby the front contact of relay 3l,- tlie Aenergization of which is under the control of line relay 7 0 connected to the line 'conductor 6. The `line `relay 70 is operatedin accordance with th'e` reception of signals transmitted from the distant station and responds to control the operation of the local relay 31 whereby the selecting magnets willbe'ene'rgi'zed in accordance with the impulses received for .recording'the desired character. A, conductor 32 which is shown extending from a contact on switch 33 may be connected with a printing ,magnet for effecting the printing of a character as determined by the operation of the selecting magnets.

The transmitting distributor comprises ya s brush aim 35 which is frictionally mounted on a constantly revolving shaft 37 as'is well known to those skilled in the art. Tlie-A arm 35 is held against i'otationby means of a' release latch under the .control ,ofla release magnet a7.- Secured to .the brush arm 35 is a pair ofbrushes 38 and39. The latter of these brushes connects the continuous ring 40 with the segineiitsftl, 42,43, ett, 45 and 46 to which the'upper armatures of the storing relays 18 to 22 inclusive, are connected, while the former bridges the continuous ring with In order that the storing relays will not be operated for storing impulses until the.

distributor arm 3 5 has completed its cycle, a relay 56 isprovided which is adapted to be energized upon the energizatio'n of any one ofthe storing relays 18v to -22-inclus`ive.A Relay 56, upon being energized, opens at its contacts, the initial energizing circuit of the storing-relays which iscompleted' through the selecting contacts of the tape transmitter previously referred to; Upon thc'passageof the brush 38 over the segment 54:, a circuit is completed including the winding of relay' 57 with a source of battery. Relay 57 in operating-opens at its contacts, the energizing circuit of relay 56 as well as the locking circuit of the storing relays. Thus, after' this relay is operatedand released, the stor- 'ing ,relays 18y to 22 inclusive, may then be actuated for storing impul s in. accordance 7U to incoming impulses whchis connected in '#75' i,

circuit withthe line conductor' andwhich v controls through its contacts, the energizing circuit. of the local relays 31 and 71 individual to the receiving 'distributors 9 and 10 respectively. Thisv line relay is of the 80 polarized type and is arranged so that its armature remains in the position setuntil 1 the reception of an impulse which reverses the position of its armature. The front and back contacts of the local relay..31 are connected witlijsegmeiit 58 ofthe receiving dis-` tributor l9 and the windingof the release.

magnet 34 respectively.. :The energization .of[4 'i l I 'the release magnet 34 is, however, controlled which, when .the brush arm is at rest, bridges the local segments 73 and 74. From this, y "-1 bythe brush 72 mountedfontlie.brush arm -29 9 relay 31, while the eiiergizationioffthe select- J ving magnets is controlled tlirouglrthe. front contact` thereof. Thus, if the front contact of this relay is closed at the time thel brush 72 is passing over asegment 75 to which the selecting magnet 28 of the printer 23 iscon'` nected, this selecting magnet vwill be-energized forcflecting the operation of the-se?v lecting mechanism,controlled thereby. This circuit'extends fromv battery through the left-hand Contact of the key 30, front contact of thelocal relay 31, segment 58 of the reiceiving distributor 9, brush 72, segment 75,' switch member 7 6 forming a part of the switch 33, contact 77 and the winding of the-selecting magnet 28` to ground.

The equipment individual to the distrib, utoi's 8 and l0 is similar in every respect. to that just described. Therefore, further dcscii'ption of this apparatus is considered unnecessary here. A

'But inasmuch as relay 56 at this time is energized, the stor- CII ing relays connected with the actuated contacts Will not be' energized. Brush'38 in passing ofi .of segment 52 opens-the energizing circ-uit of relay 36 which is thereupon deenergized and opens the energizing cir-. cuit of the release magnet for restoring the release latchto normal position for `engaging the `arm'85 after it has completed one Acycle.

tinuous ring of the'transinitting distributor `7, brush 39, segment 41,l upper aimature and alternate contact of tliestoring relay 18 to ground. The pole-changing re f lay 66 is thereupon energized 'for reversing the position of its armature and applying battery to theliiie conductor 6, the polarity 'of which is such as to reverse the position of the armature 'of the line relay 70, located at the .distant station, or to the position'v sliownfin -theydrawing y l At the .distant station, the line relay 70, inresponding to this impulse, completes the energizing circuit for the local relay 31- Which thereupon closes its front contact` and connects battery with the segment 58 of the receiving distributor9 so that upon the passage ofthe brush 72 over the segment 75,

to reverse the position o'tits armature 'sothat the local relay 31 remains deenergized. Thus, upon the. passage of the brush 7 2 over the segments to which the selecting magnets '26.aiid 27.1 otthe recorder 23 are connected,

these magnets will not be energized owing to the position of thearmature of the local relay 31.,` However, when the brush 39v engagesseginent 44, the energizing circuit for the pole-changing relay 66 will again be completed for causing the transmission of an impulse of a polarity oppositeto that 57 to ground.

Apreriously tinnsiii'itted.V The operation of the system lat the distant station idelntical with that previously described in connection with the selection of the selecting magnet 28. TheV same is true when the brush 39 passes overf'the segment 45. The selecting magnets at the distant station corresponding with the. storing relays will, of course, be

operated in the saine manner as previously describedin connection with that of the selecting magnet 28. l V

Just before the brusharm 35 is arrested by the vlatch under the control of the release magnet 47,-seginent 54 is bridged 'with the o ring l5() by .the brush 38, thereby complet- 38, segment 54 and the Winding 'of the relay opensat its left-hand'contact, the energizin'g lcircuit for relay 56 which is thereupon ing an energizing circuit for relay 57 eX- tending from battery through ring 50, brush This Arelay 571m energizing'- deeiiergized for again establishing the initial y energizing circuit for the storing relays 18 n to '22j inclusive.

as shown in the drawing thereby causing the energization of the receiving relay at the distant station for likewise completing an energizing circuit for the local relay 3,1. so

'that the release magnet,` 34 'will helpdeenergized -ust before the` arm' 29 of the vdistributor 9 as completed its cycle otrotation.

Thus,' since the release magnet 3.4 is'now" deenergized, the brush arin'29 Will beA ar- I rested dueto its engagement with the relese latch controlled by the release magnet 34.

In this manner, impulses received on the distributor 10 may be transferred and recorded on the' recorder 23 individual to the set B. It is,

thus, seen' that an operator may be stationed to observe the, operation of the ltransmitter and printer -without interfering with the.
