To dZLwhm rt in may concern: Be it known that I, J OHNC. BARCLAY, a citizen of the United'States, residing at New York,

1 in the county of New York and State of New York, have invented certain new and useful Improvements in Prin'ting- 'lelegraphs; and .i do hereby declare the following to be a full,

clear, and exact description of thef'same, such .as will enable othersskillcd-il'i the art to which IO it'appertains to make and use the same. I

My invention relates to printingtelegraphs,

and embodies certain improvements over the system set forth in n' ylat ent No. 758,732,

, dated May 3, 19041 in the present system, as

that ofmyjsaidf mtent, I employ'for the transmission oi, tl 1e messages success ons of currentpulses, which are the sam'e n number for'allthe characters, but vary in length, andthese pulses are usually, but not necessarily,

alternately of oppositedirections. For transmitting the charactersof theEnglishalphabet I employ six pulses for each message or character, whichenables me to operateatwill any one of the thirty-two rnagn-ets, thus permit- .ting the transmission of all the lettcrsof the al phabet and leaving a margin for transmission of punctuatiom'n' arksand for the operation 'ofspacing, carriage-return, shift, and paperfeed mechanism; The particular magnet corresponding to each message transm tted s-selected by the action ofprii-naryand secondary selecting-relays, a sunflower, and a separator relay,as-hcreinai ter described. 7 Myinvention consists in closing the circuit through coi'itact-points of the selectingrelays to theprinting-magnet selected throughacontact of the sunflower itself, in delaying com- 'pletion of the restoring-circuit during the operation otthe carriage-return mechanism .40

until the'carriagehas returned to its starting point, in improved means for operating the spacing mechanism without the operation of the selecting-relays, in improved shift mechanism, and, generally, in the features of invention hereinafter set forth, T and particularly pointed out in the claims.

' The objects of my invention'ar'eto improve and simplify printing telegraphsystems and apparatus and to render same more certain and rapid in their'operation,

plctc retit'rn of the carriage to its starting and to-impro've thc'shift mechanism.

1 will now proceed to describe my'inven'tion with reference to the accompanying drawing, which shows diagrammatically one embodiment of myinve'ntion comprising circuitsand apparatus for operating the mechanism of an electric printer or type-Writer. I do not illusv trate the said printer or type writer itself,-as I am not limited to. the use of any particular machine of that character, but may use any of several'such machines which are well known.

Referringjnowtothe drawing, signals incoming over the line-wire 5 actuate a Inain= line relay 4, which is the primary actuating element of'my printingrtelegraphand is the only'elemenjt of such telegraph in the ,mainline circuit. This main-line -relay may of course be difl erentially wound to 'p'ermitof positiorrto improve thespacin g mechanism,-

duplex or quadru plex operation the sameas an ordinary main line teleQ'raph-'- relay. The main-line signals for operating this relay 4: maybe produced by a hand-key orby a key board-transmitter or byany other suitable means. This particular line-relay 44 shown is of the polar type, being arranged to be actuated by changes of direction of current in the line-circuit; but obviously it may be a neutral relay instead, arranged to be operated by rise and fall of the line-current. Main-line relay 4 controls two local circuits 6 and 7, connected to opposing contact-points of the main-line relay, both of which circuits pass'through.

coils of a neutral relay 8, termed the sepa- -rator-relay, through opposing coils of a magnet/9 operating escapement mechanism of the sunflower, hereinafter described, and'through asynchionizer-magnet 28 to ground at 10. A battery 11 or other suitable source of electrical energy is connected to ground-and to the armature ofmain-line relay 4. One or the other of circuits 6 and 7 'is' completed through battery 11, according as the, saidarmature of relay-4 is in contact with therig-ht- 9 hand or left-handcontact of said relay. The

main-line relay 4 is very rapid. inaction and.

operates for each pulse produced in, the main line, whether short or long. The separatorto insure. comi relay is more sluggish in action and completes oo tooth.

the circuit which it controls only when a long i that none of these circuits through the magpulse is sent over the line. relay, however, it completes its circuit each time there is a long pulse, whether it be positive or negative. The circuit controlled by separator-relay 8 passes from ground at13, through, battery 14, the armature of separator-relay 8, and conductor to a plate 16 of the sunflower, to which the first five contact:

points 17, 18, 19, 20, and 21 of that sunflower are electrically connected. This sunflower is of the type described in the patent to Bankingham, No. 544,347, dated August 18, 1895, and con'sists of contact-points 17, 18,19, 20, 21, and 22, adapted to be actuated successively by teeth of aratchet-wheel 23 during movement of said wheel through the space of one Said ratchet-wheel is mounted upon a shaft 24, upon which is also mounted an escapement-wheel 25, having three times the number of teeth of ratchet-wheel 23 and controlled in its movement by the escapement-' v 9, through which circuits 6 and 7 pass, beingoppositely wound, alternate pulses in thesecircuits will cause the vibration of the escapement-anchor 26, and six such pulses, permittingrotation of escapement-wheel 25 through the space of three teeth, will advance ratchetwheel 23-through the space of one'tooth, causing contact-points 17 to 22 to complete their respective contacts successively and complet- Being a neutral ing one cycle operation of the sunflower. The

shaft24 of the sunfloweris driven by any suitable device, such as a spring-motor or friction drive,which will permit intermittent motion of said shaft. Magnet 28 beneath the sunflower is a synehronizer-magnet operating an armature-lever 29, having a hook adapted to engage the teeth of ratchet-wheel 23. The' function of this synchronizer is fully described in the patent to Buckingham, No. 544,347, and need not be further described here, since its description is not necessary for the understanding of the operation of the apparatus. Indeed, if automatic correction-of the operation of the apparatus for loss of synchronism between the receiver and transmitter is not desired this synchronizer may be omitted.

It was stated above that the metal frame 16, carrying contact-points 17 to 21, is connected by conductor 15, passing through contacts of separator-relay 8, with battery 14 and thence to ground. These contact-points 17 to 21, in-

clusive, which may be termed ele'ctor-con tacts, when operated by the movement of ratchetwheel 23 complete circuits successively from the contact-points of separatorrelay 8 through conductors 30 to 34, respectively, leading to the magnets of polar selecting- relays 35, 36, 37 38, and 39, respectively, and thence through a common return-conductor 4 ,-round at 41; but it will be seen nets of the polar selecting-relays will be closed unless at the instant when any one of those circuits is closed through the sunflower the transmission of a long pulse through the line has caused separator-relay 8 to complete the circuit through battery 14 to ground at 13. Polar selecting-relays to 39, inclusive, control circuits of secondary selecting- relays 42, 43, 44, 45, and 46, respectively, the contactpoints of which are connected in tandem in the order named, the five series of contactpoints forming an arithmetical progression. In my said former application each secondary selecting-relay has but one movable contactpiece, there being therefore two relays in series 43, four relays in series 44, eight relays in sqies 45, and sixteen relays inseries 46. In mypresent system 1 illustrate the employment of an alternative and equivalent construction'xinvolving the mounting of a plurality of contact-points on the relay-armatures, so

that there is but one relay 43, one relay 44, two relays 45, and four relays 46, each of the. relays 44, 45, and 46 having four contactpoints. It of course will be practicable to mount a greater number of contact-points upon the armatures, and thereby to red uce the number of relays and 46. The electrical ctfect however, is the same, whether each contact-point is operated by an' independent magnet or whether a plurality of contactpoints of the same series are grouped together for operation by a single magnet. The primary selecting-relays 35 to 39, inclusive, each controls a circuit of a corresponding secondaryselecting relay or relays. ling-circuits of these secondaryselecting-relays 42 to 46, inclusive, are normally'broken; but the armatures of. the several primary selecting-relays are connected by amultiple-current lead 49 to a battery 50 and to ground, and when themagnet of any one polar selecting-relay is energized by a current passing through the sunflower and its armature is deflected said The control polar selecting-relay completes the circuit relays to their normal positions, breaking the circuits of thesecondary selectingrelays 42 to 46, inclusive. ranged to be completed by a restoring-relay 53 after circuit is completed through the sixth contact-piece 22 of the sunflower, as hereinafter described. 1

Referring now to the secondary selecting- This restoring-circuit 52 is arwin - relays areconnected in tandem'as follows: Re-

It will be seen that by means of the various secondary selecting-relays 42 to 46,, inelusive, any one of the various magnets'60- maybe selected at will-for the comriletion This giZed-upon the closing of the sixth sunflowercontact f.2.

circuit 54 was'elosed by a separate relay -operated by a circuit passing tl'iroug'l'i the sixth sunflower-contact, to a multiple branchof which circuit was connected the restoringrelay 53, the said relay controlling circuit 54 being arranged to operate more rapidly than said restoring-relay, so that circuit 54 is com- .pleted through whichever magnet has been selected before the armatures of the secondary selecting-relays are returned to normal as a result of the completion of the restoringcireuit 52. Instead of employing a separate relay for completing the circuit 54 i now complete said clrcuit-tln-ough the sixth co'ntact-point of the sunflower, thereliy obtaining a greater margin ot'tinie for the opera.-

the stop'67, but arranged to he moved mechanically out of contact with such stop 67 when thecarrlage68' (shown diagrammatically only in the drawing) has i'eturned eompletely to its starting-point.

This spacingrelay 71 is connected in multiple with restoring-relay in a circuit-closed by the completion of the sixth sunflower-contact, and like relay 53 relay 71. is somewhat sluggish, so much so that upon the transmission of a message consisting only of dots it permits the circuit of magnet l) to remain closed long enough for the operation of the spacing mechanism, but nevertheless breaks said circuit of magnet 70 after the: transmission of any signal which causes the operation of one or more of the secondary selecting-relays before through the operation of the restoring-relay 53 the armatures of said secondary selecting-relays can have reached their back-stops.

S/Ifflf nwc/mnism.---This mechanism may be either a carriage-shift or type-shift, as preferred.- In the drawing 1 have indicated diagrammatically a typeshift; but it will be understood that I do not limit myself thereto. This shift mechanism 73 comprises a magnet 74, ;n'ranged to be energized upon the transmission of a suitable corresponding selective signal and when energized to attract its armature 75, thereby operating the shift mechanism. ln'the drawinglhave indicated diagrammatically a type-wheel 76, arranged to be shifted by this movement of the armature. The shift mechanism is held in its shifted position by a detent-lever 7", controlled by a magnet 78, which magnet is located in a multiple branch 79 of the spacing-circuit 69, which branch, however, does not pass through contact 72 of the shift mechanism. By this ar rangementl am able to use the ordinary spacing-signal for releasing the shift mechanism and permitting it to returnto nonmal condi tion. When the shift-mechanism is in normal position, detent-lever 77 is operated in unison with the spacing mechanism of magnet 70 each time a spacing-signal is set, but operates idly; but when the shift mechanism has been oper-. ated and is held locked by the detent 77 the releasing the spacing mechanism and permitting it to return to normal position.

1 bye/' feed. -For operating paper feed mechanism I employ a magnet 80 in 'one of the circuits controlled by the selecting-relays, which circuit, like the circuit of the magnet 60, will be completed when the corresponding message is transmitted. No particular paper feed mechanism isillustrated, and any mechanism suitable for the purpose may be employed. v i

In the above arrangement of circuits and apparatus I have employed the spacing-circuit for operating the shift-release; but it will be obvious that I may use any other circuit instead. I prefer, however, to employ the spacing-circuit for releasing the shift mechanism, since this spacing-circuit operates especially rapidly.

The following will serve as an illustration of how any-one of the various magnets may .be selected at will. Suppose that the particular magnet to be selected is one the signal for selecting which'is as follows: Upon the sending of the first dash the armature of line-relay 4 will be deflected to the right, thus causing sunflower-contact 17 to close, and since the dash continues long enough for separator-relay 8 to operate a circuit will be completed from ground at 13, through battery 14, selector-contact 17, and primary selecting-relay 35, to ground at 4:1: Relay 35 being thus operated will complete the circuit through the secondary selecting-relay 42, moving the armature thereof to the position opposite that shown in the drawing. The next succeeding signal being a dot, line-relay. 4: and the sunflower escapement mechanism will be operated; but separator-relay 8 will not operate sufliciently to close a circuit through the second primary selecting-relay 36. The third signal being a dash, a circuit will be completed through primary selectingrelay 37; which in turn will close a circuit through the magnet of relay 4 t, moving the armature of said relay to the position opposite that shown in the drawing. The fourth signal being also a dash, primary selectingrelay 38 will be operated and will close the circuit through secondary selecting-relays 45, moving the armatures of said relays to the position opposite that shown in the drawin The next succeeding signal being a dot, primary selecting-relay 39 and secondary selecting-relays 46 will not be operated. By. the operation of the various secondary selecting-relays connection has been established from conductor 54 through the armature of relay 42 to conductor 59, thence through one of the contacts of said relay to conduptor 81, thence through one of the contacts of relay 44 to condoctor 89, thence through one of the contacts oi? the r1ght=hand relay 4:5 to conductor 83, and thence through one of the contacts ofthe third relay a6 to a conductor 8% and to one printing rnagnets, marked 60*, which is the particular magnet tobe selected. Upon the sending of the sixth signal, which is a'da'sh,

a circuit will he closed from ground at 56., through battery 55, sunflower-contact 22 and,

vire a, and through the conductors 59181 82 '83 eaand magnet 60?,t0' ground. Atthe'sarne- I time a. circuit will be completed from sun:

flower-contact 22 through the restoring-relay 53,,and still another eir'euit 'will be completed from. sunflower contact 221'- through spacing cut-out relay 71. These two relays, however,

' operate more sluggishly than do the printingniagnets, -and hence will not operate to restore the selecting-rcla v'sand cut out the spacingrelay until afterthemechanism'controlled by magnet is'operated. It willbe obvious that by var ations in the number and arrangeinent of the dots and dashes of. the message transmitted any desired magnet of series '60- may be selected and a circuit completedtherethrough;

It will be obvious t-hat-in'y invention is. sus-- ce pt'ible or many variations. and modifications without departing from the'principles herein set forth, and I do notlimit myself to the details of construction and arrangexncnt-of-thej parts herein illustrated and described. What I olai1n.is.--.
