Unto stares rarest @FFECE CHARLES K. JONES, OF KANSAS CITY, MISSOURI.

PRINTING-TELEGRAPH.

To all whom it may concern:

Be it known that I, CHARLES K. JONES, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Printing- Telegraphs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to printing-telegraphs; and it consists in a novel arrangement of circuit-forming relays, selectingrelays and associated devices whereby by the operation of a single main-line circuitcontrolling the selective action of the said relays any one of a plurality of type-bars or printing devices may be actuated at will and other actuations be accomplished for vari ous operating purposes.

My invention consists of apparatus whereby automatic protection is provided to the receiving instrument against destruction by a powerful electric energy such as is necessarily used in an instrumentof this character and thereby making it possible to operate my invention in small private oliices and in places of ordinary business for the receipt of private telegraphic correspond ence, stock or market quotations, bulletins press despatches, etc; of apparatus whereby the instrument may be adjusted to correspond with the speed of the transmitter; of apparatus whereby a plurality of sets of printing or operating-magnets are available for any purpose desired, so that one set may be used for the small letters, figures and punctuation-marks and operating purposes and another set for the capital letters, figures, punctuation-marks and operating purposes and another set for italic letters and other purposes; and generally my invention consists in the novel features hereinafter set forth, and particularly pointed out in the claims.

The objects of my invention are to improve and simplify printing-telegraph sys tems and apparatus, to simplify and improve the operation of printers employing Specification of Letters Patent.

Application filed September 14, 1909.

Serial No. 517,742.

type-bars or similar printing-devices for the several characters; to provide apparatus whereby the ordinary dot and dashcode of telegraphy may be received and translated into printed characters or be used for any other purposes desired; to provide a receiving printing instrument adapted for operation by any type of transmitter ranging from the slowest to the highest speed instrum-ent.

I have illustrated three sets of printing and operating-magnets which are controlled by what will be cesignated as circuitmaking relays and it will be obvious from a further understanding of the method of operation that these sets may be increased or diminished as may be desired by following out the same method illustrated and I claim the privilege of so doing,

I will now proceed to describe my invention with reference to the accompanying drawings, in which one embodimentof the invention is illustrated and will then point out the novel features in claims.

In the said drawings, Figure 1 is a diagram showing an ordinary hand-manipulated telegraph-key for a transmitter and the various relays, type-bar magnets, operating-magnets, and circuits of the corresponding receiving instrument or printer. Fig. 2, illustrates one form of type-bar mechanism adapted to be actuated by typebar magnets. Fig. 3, is a view in side elevation of one of the selecting-relays. Fig. '-ii-., is a horizontal sectional view on the line .1jh of Fig. 3.

In this system I employ for the transmission of the messages current pulses, but said pulses vary in length, the short pulses representing dots and the long pulses representing dashes, and these pulses are usually, but not necessarily, alternately of opposite directions. For transmitting the characters of the English alphabet I may employ from one to siX dots or dashes, or combinations of dots and dashes. This number of dots and dashes would give ample operating-magnets, which would be sixty-four magnets, permitting the transmission of the alphabet, numerals, punctuation-marks and for the operation of spacing, carriage-return and shift mechanism, such as are used on various well v known electrical-type-writers and leaving a margin for any other purposes that may be desired. For transmitting a less number of characters than are contained in the alphabet I may employ a fewer number of dots and dashes and for transmitting a greater number of characters than are provided for herein 1 may employ more than six dots or dashes or combinations of dots and dashes.

In the accompanying drawings 1 have illustrated apparatus for receiving and printing adapted for operation by a code consisting oil a maximum number of tour dots or tour dashes or combinations of this number of dots and dashes, this being done for the purpose of obviating an unnecessary lengthy description, as it is clearly obvious that the system may be ext-ended to any limit desired by following out the same method herein pursued.

Referring now to the drawings and at first to Fig. 1, the said figure shows an ordinary telegraph-hand-manipulated key for a transmitter, said type of transmitter being chosen for illustration on account of its simplicity as compared with the Wheatstone transmitter or other types of complicated transmitters, for be it understood that the receiving apparatus illustrated herein is adapted for operation by any type of transmitter, all that is necessary being that the main-line relay be connected to the receiving instrument as illustrated, viz. through the opposing-contacts and having the armature connected to one pole of a battery and the other pole of said battery connected to ground, so that the pulses received by the main-line relay will be relayed to the receiver, and I claim the privilege of so operating, the transmitter being no part of my invention, but simply used in the illustration for the purpose of explaining more fully the operation of the receiver or printer; the operation of the transmitter will be described more fully hereinafter; and a receiving instrument comprising a main-line relay 1, and a plurality of relays hereinafter described. The receiving instrument and transmitter are connected by a line-wire 2. At the transmitting end this line-wire passes through contacts of an ordinary pole-changer 3, forming a part of the transmitter and operated by a local circuit controlled by contacts of the transmitter. At the receiving end the line-wire 2, passes through main-line relay 1, which in the instance shown is a polar relay, to ground. Main-line relay 1, controls two local circuits 4 and 5, connected to opposing contactpoints of the main-line relay. A battery 6, or other suitable source of electric energy is connected to ground and to the armature of main-line relay 1. One or the other of circuits 4c and 5 is completed through battery 6 according as the said armature of relay 1, is in contact with the right-hand or left-hand contacts of said relay, however this is not true until the first pulse actuates the armature of main-line relay 1 into the abnormal position, this being for the purpose of opening a circuit between battery (5 and the instrument intervening between one complete operation of a characteristic signal and the beginning of the succeeding characteristic signal. Circuit 5 is formed by the first operation of main-line relay 1, which operates relay 24 (designated as entrance-relay) into the abnormal position and relay 24: remains in such position until relay 22 is operated which operation completes a circuit passing through the restoring-coils of relay 2 1 and thus restoring it to normal position; the operation of relay 22 also completes the print-circuit which will be explained herein after. A condenser 8, is connected across the contact-points of the relay 1, to reduce sparking.

Referring now to the transmitter, the same as shown in the drawings, consists of an ordinary hand-manipulated telegraph-key 9, adapted for engagement with contact 10, which is connected to magnet 3 of the polechanger, thence to battery 11 by conductor, and by conductor from battery 11 returning to key 9; key 9 is held normally in one position by spring 1 1-. Magnet 3 controls the spring-held armature of an ordinary polechanger, which pole-changer in its operation places alternately on the line-circuit sources of electric energy or batteries 12 and 13 of opposite polarity, thereby producing in the line-conductor 2, current pulses of opposite polarity.

The function of the entrance-relay 2 1-, is to protect the parts from injury resulting from a prolonged energization from battery 6, intervening between characteristic signals.

On account of a thorough description be ing made explaining the operation of the instrument in a number of characteristic signals which follow, a brief description of the instrument will here sul'lice: The receiving instrument consists of a number of polar relays having restoring-coils and a number of neutral relays said polar and neutral relays being designated as circuittorming relays; a group of polar relays having restoring-coils being desi nated as circuit-making relays and number of neutral relays being designated as selecting-relays. The receiving instrument as illustrated is in the normal or open-circuit position with no electric current into its parts in perceptible activity except to the mainline relay 1 from battery 12. There are four selecting-relays corresponding to the maximum number of pulses composing the code herein used and these relays are not operated except by the long or dash pulses. For purposes of description the selectingrelays will be designated as in clusters on account of said relays of the second, third and fourth clusters having a plurality of contact-points with spring-plates for engagement therewith as illustrated in Figs. 3 and at. The relay of the first cluster is an ordinary neutral relay having two contactpoints, the relay of the second cluster has four contact-points and four spring-plates for engagement therewith, the relay of the third cluster has eight contact-points and eight spring-plates for engagement therewith. and the relay of the fourth cluster has sixteen contact-points and sixteen springplates for engagement therewith. The contact-points of the selecting-relays are connected one to another as follows: One of the contact-points of the relay of the first cluster is connected by conductors to each contact-point of two of the contact-points of the relay of the second cluster, the other contact-point of the relay of the first cluster is connected by conductors similarly with the remaining two contact-points of the relay of the second cluster, the four spring plates of the relay of the second cluster are connected by conductors in a similar manner to the contact-points of the relay of the third cluster, and in like manner the re maining clusters are connected one to another, the relay of the fourth cluster having therefore sixteen contact-points connected by conductors to the preceding cluster, and sixteen spring-plates remaining are connected by conductors to their respective printing or operating-magnets of a set which is designated as set 25 the other terminals of said magnets are connected to amultiple lead 103, thence by wire 10-1, through the armature of circuit-making relay 29, wire 106, through armature of circuitmaking relay 28 and to ground at 108. Three of the spring-plates of the relay of the last cluster are connected in circuits passing through the coils of their respective circuit-making relays 28, 29, 30 and 31, and to ground, the object of which being to control the

sets

25, 26 and 27. The printing and operating-magnets in set 26 are connected by conductors to their respective spring-plates of the-relay of the last cluster and the other terminals of said magnets are connected to a multiple lead 123, to contactpoint of circuit-making relay 30, the armature of relay 30 connected by conductor 124 to a contact of relay 28,the armature of circuit-making relay 28 is connected to wire 107 leading to ground at 108. The printing and operating magnets of set 27 are connected in a similar manner to their respective spring-plates of the relay of the last cluster and the other terminals of said magnets are connected to a multiple lead 132 and thence to a contact-point of circuit-making relay 31, the armature of relay 31 is connected to ground at 133. Two printing or operating-magnets only are shown in each of the sets 26 and 27, but it will be understood that there are circuits available for operating thirteen of such magnets in each of said sets and the claims will there= fore be drawn accordingly.

It will be noted that the circuits available for operation by the selecting-relays are in geometrical progression. The printing and operating-magnets in set 25 are illustrated as being normally in circuit with contacts of said selecting-relays of the last cluster and if it be desired to cut out of circuit set 25 and to cut into circuit set 26, it will be necessary to operate the characteristic signal controlling the operation of circuit-making relay 28, which will consummate the purpose by opening one multiple lead and making another multiple lead good to ground through circuits controlled by the circuitmaking relays; if it be desired to cut outof circuit the set 26 and to cut into circuit the set 27, it will be necessary to operate the characteristic signal controlling the operation of circuit-making relays 29, 30 and 31, which relays are connected in electrical series for simultaneous operation and the desire is consummated by opening one multiple lead while another multiple lead is made good to ground; to restore the sets totheir normal position it is necessary to operate the characteristic signal controlling the operation of the circuit-making relays 28, 29, 30 and 31, which relays are connected in electrical series for-simultaneous operation and the purpose is accomplished by opening two multiple leads while the multiple lead of set 25 is made good to ground.

The magnets comprising the

sets

25, 26 and 27, may be termed type-bar and operating-magnets or printing and operating-magnets, though as hereinafter shown, certain of these magnets may operate shift mechanism, space mechanism, carriage-returning mechanism, or the like.

Each selecting-relay is connected in a circuit controlled by a corresponding circuitforming relay and each such circuit is adapted for operation successively, by the dash or long pulses. For convenience of description we will designate the four circuit-forming relays which control the four selecting-ree lays as the dash-relay, or dash-relays.

There are two sets of neutral relays comprising the circui t-forming relays, which sets comprise relays adapted for operation successively, the last relay in each set being operated only by the dashes or long pulses. A switch 57, in one set, and switch 77, in the other set are adapted for engagement with the contacts 143 and 144.- and 143 and 14. 1 respectively, for the purpose of cutting out of circuit one or more of the relays in said sets, thereby adapting the receiving instrument to a faster speed. Should a slower speed than is herein illustrated be desired then it will be necessary to increase the numher of the relays comprising said sets, and I claim the privilege of so doing. The two sets of neutral relays are controlled by the main-line relay, one set being controlled by one contact and the other set being controlled by the other contact; one set enibracing relay 17, is for completing the circuits controlling the operation of the dash relays 109, 110, 111 and 63 and the lastnamed relays control the selecting-relays as previously stated; the other set of neutral circuit-forming relays is for the purpose of completing the print-circuit and the restoration-circuit, relays 22 and 23, designated as the print-relay and the restoring-relay, when operated accomplishing this purpose. It will therefore be obvious that a print and restoration may be el'lected with the second, fourth, sixth or eighth pulse operated the requirement being that the transmitter remain in the normal position long enough for the relays 18 to 23 inclusive to be operated successively.

Two printing or operating-magnets may be controlled by two pulses operated by the main-line relay said magnets being in set- 25; two magnets in set 26 and two of said magnets in set 27 may be controlled by two pulses operated by the main-line relay, but as previously explained the multiple leads controlling the circuits of the sets must be changed by the operation of the circuit-making relays before the magnets in sets 26 and 27 can be operated; similarly, two others of said magnets may be controlled by the oper ation of tour pulses by the main-line relay; a total of sixteen selecting-circuits are available for operation in set 25 by the operation of the code 01 two to eight pulses by the main-line relay. The dash-completing relay 17, is operated by a long pulse or dash operated by the main-line relay in the first, third, fitth and seventh pulses. The restoration leaves the various relays in position for the first pulse operated by the main-line relay 1, beginning a characteristic signal; it the first pulse be a dot or short pulse the polar relays of the circuit-forming relays are not operated, but it the first pulse be a dash then relay 17 is operated thus completing a circuit which passes through the armature of relay 39 via conductor to a plate contact on the armature of relay 40, but said plate is insulated from said armature, thence to contact of relay 10, thence through the coils of the first dash-relay 109, and to ground and thus operating said dash-relay; the operation of the dash-relay 109 completes a circuit through. the contacts of relay 109 thus operating the selecting-relay of the first cluster and the relay 109 and the said selecting-relay will remain in such position until the restoration takes place; the second pulse if a short pulse will not operate the extreme relays 22 and 23 but will operate polar relays -39 and 4:0 in a circuit passing through the coils of said relays and to ground and thereby severing a circuit by the operation of relay 10 through which relay 109 was operated, and also forming a circuit through the armature of relay 40 and its lower contact for the operation of relay 43 by the third pulse, and the operation of relay 39 forming a circuit through its other contact whereby the third pulse may operate the second dash-relay 110, it perchance there be a dash occurring in the third pulse; the third pulse operated will operate polar relay 4:3, in a circuit via conductor 41, through the armature of polar relay 10 and its lower contact, through the coils of relay 43 and to ground, and thus forming a circuit through the contacts of relay 13 for the operation of the fourth pulse; if the third pulse be a dash then relay 17 is operated thereby completing a circuit from wire 60, through the armature of polar relay 39 and its lower contact, thence by conductor through the contact and through the plate on the armature of relay 46, but said plate is insulated from said armature, thence by conductor through the coils of the second dash-relay 110, and to ground, and thus operating the second dash-relay, which second dash-relay will in turn complete a circuit through its contact which will operate the selecting-relay of the second cluster; the fourth pulse will operate relays 4L6 and 47, by a circuit passing through the armature of relay 43 and its lower contact and through the coils of relays 16 and 47, to ground, thus severing the circuit through which the second dash-relay 110 was operated, the circuit being opened by the armature of relay 46 leaving the upper contact, the change of position of the arinature of relay 416 also torming a circuit for the operation of relay 50 by the fifth pulse, the operation of relay 47 forming a circuit through its contacts for the operation of relay 111, the third dash relay, by the fifth pulse; the operation of the fifth pulse will operate polar relay 50 in a circuit via wires 41 and tS through the armature of relay 46 and through the coils of relay 50 to ground, thus forming a circuit through the contacts of relay 50 for the operation of the sixth pulse; it the fifth pulse be a dash then relay 17 is operated thus completing a circuit via conductor 60, through the contacts and armature of relay 17, through the upper contact and the plate on the armature of relay 54, said plate insulated from said armature, through the coils of relay 111, the third dash-relay, and to ground, thus operating the third dash relay, which in turn will operate the selecting-relay in the third cluster; the sixth pulse operates polar relays 5 1 and 55 in a circuit via wire 38, through the armature and up per contact of relay 51, through the armature and lower contact of relay 50, and through the coils of relays 54 and 55 and to ground, thus severing the circuit through which the third dash was effected said opening occurring when the armature of relay 54 leaves its upper contact, and when said armature makes its lower contact, a circuit is formed for the operation of relay 51 by the seventh pulse, the operation of relay 55 forms a circuit for the operation of the fourth dash-relay if there be one occurring in the seventh pulse; the seventh pulse operates relay 51 in a circuit passing through the armature of relay 54 and through the coils of relay 51 and to ground, thus severing through the contacts of relay 51, the circuit which operated the relays 54 and 55 in the sixth pulse and efiecting a saving in operating current; if the seventh pulse be a dash then relay 17 is operated and a completing circuit is operated from ground 7, through battery 6 through armature of relay 1, wire 4, through the armatures of relays 15, 16 and 17 to wire 60, it will be understood from what has previously been stated that the relays 15, 16 and 17 are operated successively thus forming a circuit through their contacts to wire 60, from wire 60 to Wire 61, through the armature of relay 55, wire 62 and through the coils of the fourth dash-relay 63 to ground, thus operating relay 63, which in turn completes a circuit through its contacts which operates the fourth cluster relay in a circuit from ground 64, through multiple lead 66, through the armature and contact of relay 63, wire 67, through the coils of relay 68 and to ground at 69; if all the four pulses operated be dashes then all the polar relays comprising the circuit-forming relays will now be in the abnormal position; the eighth and final pulse comprising the code of operation will energize the magnets of polar relays 39, 40, 46 and 47, but there will be no actuation of the armatures of said relays for the reason that these armatures are already in the abnormal position, and said energization will continue until the entrancerelay is operated which will break the connection to battery 6 and deenergization will follow; the eighth pulse will operate the neutral relay set comprising relays 18 to 23, inclusive, and the operation of the final. relays 22 and 23, which operation occurs successively, will cause a print to ensue or cause the energization of an operating-magnet from a circuit starting from round at 89, through the coils of entrance relays 24, thereby restoring entrance-relay 24 to normal position, wire 90, through battery 91, through the contacts of relay 22, wire 92, through the armature of the selecting-relay of the first cluster and through the contacts of said relay and through the contacts of others of the selecting-relays to the selected printing or operating-magnet, through multiple lead 103, wire 104, through armature of circuit-making relay 29 L0 Wire 10%, through armature of circuit-making relay 28 and to ground, thus energizing said selected printing or operating-magnet; the operation of relay 23 which follows very quickly the operation of relay 22, completes a circuit through the restoring-coils of all the polar relays except the entrance relay and the parts are restored to normal position.

The operation of this apparatus is as follows: supposing, for example, that the message to be transmitted consists of three dots followed by a dash; the transmitter 9 is depressed or closed so that it makes contact with 10, and then said transmitter is released so that it will be carried back to the normal position by spring 14; this will energize magnet 3, and the pole-changer actuated so that battery 13 is placed to the line and circuit 4 will be completed to relay 15. The first operation being a dot or short pulse, the armature of the main-line relay 1, does not remain in contact with circuit 4 long enough for the operation of relays 16 and 17 to take place; another circuit 32 is connected to circuit 4 passing through an adjustable resistance 33 thence through the coils of polar relay 24, the entrance-relay, to ground, thus effecting a circuit whereby the main-line relay 1, may cause operations of the various parts when its armature is returned to the normal position after the first pulse; when the armature or" main-line relay 1 is actuated to the normal position a circuit is made as follows: wire 5, armature of polar relay 24, wire 34, relay 18 to ground; as the relay 1 will not remain in the normal position long the remainder of the relays 19, 20, 21, etc. embracing the neutral relay set will not be operated; a branch circuit 35 is connected with wire 34 which leads to the armature or relay 18; another branch circuit is connected to wire 35, it being conductor 36, thence to wire 38, through the coils of

polar relays

39 and 40 to ground, thus actuating the armatures of

relays

39 and 40 to the abnormal position and they will remain so until all the parts are restored to normal position. The next operation being a dot, the transmitter is operated the same as with the first dot and the main-line relay 1 is operated into the abnormal position and the result will be the same as described in the first dot but there will be no further actuation of the entrance-relay 24 until the parts are restored to normal; an additional circuit will now be operated as follows: connected with wire 4 is a branch wire 41, leading to the armature of polar relay 40, thence to wire 42 and through the coils of polar relay .43 to ground, thus actuating the armature of polar relay 43 into the abnormal position.

The second dot being completed the armature of main-line relay 1 is actuated into the normal position and the following circuits are made: relay 18, is operated as in the previous operation and in addition thereto a circuit is made from wire 81 to wire 35, wire 36, wire 38, wire 1%, armature of polar relay 18 to wire 15, through the coils of polar relays d6 and 17 to ground, thus op erating relays 16 and 47 into the abnormal position.

The third dot calls for the same operation of the transmitter as the previous dots and the operations on the parts will be the same as the previous ones, except that the circuit will now run from wire a to wire 4:1, wire 18, through armature of relay 16, wire 49, through the coils of relay 50 and to ground, thus operating relay 50. The third dot being completed the armature of the main-line relay 1, is operated into the normal position with the following result: in addition to the operation of relay 18, the circuit goes from wire 341 to wire 85, to wire 36, wire 88, armature of relay 51, wire 52, armature of relay 50, wire 58, through the coils of relays 54s and 55 to ground, thus operating relays 51 and The next transmission being a dash, the transmitter is held in contact with 10, for a longer period than for the dot and the following operations result: relay 15 is operated thus causing another circuit to be made from wire a, through the armature of relay 15 to wire 56, switch 57, wire 58, magnet of relay 16 and to ground, the energization of the magnets of relays 15 and 16 resulting in the actuations of their respective armatures, from wire 58 through the armature of relay 16 to wire 59, thence to magnet of relay 1'? and to ground, thus energizing the magnet of relay 17 and causing its armature to actuate, this actuation causing another circuit to be made from wire 59 through the armature of relay 17 to wire 60, thence to wire 61, armature of relay 55 to wire 62, through the coils of relay 63 to ground, thus causing the operation of relay 63; another circuit is now made fro-m ground 6-1 through battery 65, wire 66, through armature of relay 63, wire 67, magnet of relay 68 and to ground at 69, thus actuating the armature of relay 68, there to remain until the parts are restored to normal; the operation of relay 68 reverses the positions of spring-contacts 70 and 71, connection being now broken between 70 and 72 and connection being made between 71 and 73. Another circuit makes follows:

wire 4 to wire 41-1, wire 74: through the armature of relay 541, to wire (5, through the coils of relay 51 and to ground, thus actuating the armature of relay 51.

The dash being now completed the armature of main line relay 1, is actuated into the normal position and the following circuits ensue: wire 5, through armature of relay 24, wire 34:, through magnet 18 to ground, thus operating relay 18, which makes a circuit from wire 3st, through the armature of relay 18, to wire 76, switch 77, wire 7 8, through magnet of relay 19, and to ground; the armature of relay 19 is actuated and make another circuit from wire 78, branch wire 79, through the armature of relay 19 to wire and through the magnet of relay 20 and to ground, this ope "ates relay 20 and makes circuit from wire 80, branch 81, through the armature of relay 20 to wire 82, through the magnets of relays 21 and 22 and to ground, thus operating the relays 21 and The operation of relay 22, makes the following circuit: from ground at 89, through the coils of relay 2 1 (the entiancerelay), to wire 90, through battery 91, through. the armature of relay 22, wire 92, through the armature of relay 93, conductor 941 to springcontact 95, wire 96 to spring-contact 97, wire 98, wire 99, spring-contact 100, wire 101, through type-bar magnet 102 to wire 108, wire 10st, through armature of relay 29 to wire 106, through armature of circuit-n'iaking relay 28 to wire 10'? and to ground at 108, thus restoring the entrance-relay 24: to normal position and effecting an energization of the type-bar magnet 102, and the corresponding type-bar is operated.

Immediately following the print, the parts are restored to normal in the following manner: when relay 21 is operated another circuit is made from wire 82 to wire 88, through the armature of relay 21 to wire through magnet of relay 23 and to ground, thus operating relay and the operation of relay 23 completes a restoring-circuit from ground 85, through battery 86, through armature of relay 28 to wire 87, thence through the restoring-coils of polar relays 39, 10. 16, it, 54:, 13, 50, 51, 109, 110, 111, and (as: and to ground at 88. The operation of polar relays 109, 110, 111 and 63 to the normal position breaks the circuits controlling relays 93, 112, 1.13 and 68 and their respective springs actuate their armatures to the normal position. It will he understood however, that in the operation just described only one of these relays were operated, it being relay 68.

It will be seen that by following out the method previously described, a circuit may be completed through any one of the various type-bar magnets 25 at will, and through any one of the corresponding magnets in sets 26 and 27 after the proper operations are made with the circuit-making relays as explained.

I will now describe the operation of the circuits controlling the sets of printing and operating-magnets: if the set- 26 is desired to be cut into circuit with the selecting-relays, four dashes will be requir d to effect the purpose and the relays 93, 112, 113 and 68 will be operated and a circuit will be made as follows with the completion of the said four dashes, similarly as described in the energization of type-bar magnet 102: from ground 89, through the coils of entrance-relay 24:, wire 90, battery 91, through armature of relay 22, to wire 92, through the armature of relay 93, wire 94, wire lltt, spring-contact 115, wire 116, spring-contact 117, wire 118, spring-contact 119, through the magnet of circuit-making relay 28 and to ground, thus operating relay 28. If the same operations are now effected which resulted in the energization of the typebar magnet 102, in the set 25, as previously described, the circuit will be as follows: from springcontact 100, wire 101, wire 126, typebar magnet 125, wire 123, armature of relay 30 (circuit-making relay), wire 12%, armature of circuit-making relay 28, wire 107 and to ground at 108, thus energizing the typebar magnet 125, in set 26, which magnet corresponds with the type-bar magnet 102 in set To cut into circuit the third set 27, with the selecting-relays, three dashes are necessary to effect the pro-per operations of circuit-making relays 29, 30 and 31 and when said operations are accomplished the follow ing circuit will be made: from ground at 89, through the coils of entrance-relay 24, wire 90, through battery 91, armature of relay 22, wire 92, armature of selecting-relay 93, wire 94, wire 1'14, spring-contact 115, wire 116, spring-contact 117, wire 118, wire 128, spring-contact 127, through the coils of the circuitmaking relays 29, 30 and 31, to ground at 165, resulting in the operation of the three last-named relays, which will make a circuit as follows, when it is desired to energize the type-bar magnet 131, in set 27, said type-bar magnet corresponding to the type-bar magnets 102 and 125 in sets 25 and 26, and assuming that the circuit has been operated similarly as previously described in the energization of type-bar magnet 102, so that spring-contact 100, is operated into engagement with wire 99: from spring-contact 100, wire 101, wire 126, wire 130, type-bar magnet 131, wire 132, armature of circuitmaking relay 31 and to ground at 133, thus energizing type-bar magnet 131. To restore the

sets

25, 26 and 27 to normal, it will be necessary that the proper combination of operations be effected, similarly as previously described, which will result in the spring-contact 13 1 being brought into en gagement with wire 135, which will result in the operation of the circuit-making relays 28, 29, 30 and 31, which relays are connected in electrical series for simultaneous operation, via wires 160,161,162,163, and 164 and to ground at 165. The armatures of all the polar relays tend to remain in contact with whatever contact-pomt they are 111 contact at the time. These relays are provided with a second or restoring-circuit for returning their armatures to the normal position.

In Fig. I have shown mechanism for operating type-bars by electromagnets, the parts-there shown being an ordinary typewriter roll or platen 138, type-bars 139, connected by links 140, to armature-levers 1411, adapted to be operated by the printingmagnets 142; but it will be understood that I do not limit myself to any particular printing mechanism and that the mechanism of any of the well-known electrical typewriters maybe used. Further, it will be understood that certain of the magnets 1&2, may operate shift, spacing, and carriagereturn mechanism such as are commonly used in electrical type-writers, such magnets acting directly or as relays to complete the circuit of other magnets.

In Figs. 3 and 41. I have shown a relay for operating a plurality of oppositely-opposed spring-contact connections, adapted'to be operated by polar relays 110, 111 and 63, but it will be understood that I do not limit myself to this particular type of springcontact connection as such parts may be made in various ways. Referring to the parts, 68 is an armature-lever pivoted on support 146. said support having a base 147; adjustable screws 150 and 150 are carried by

supports

146 and 148, to limit the travel of the armature 68. Screws 150 and 150 are adapted to carry wires 99 and 99. Another support 149, carries two sets of oppositely-opposed spring-plates, adapted for alternate engagement with screws 150 and 150.

Screws

151 and 151 are for holding wires 101 and 101. A spring 157 holds the armature 68 normally in one position and magnet 68 is adapted when energized to actuate the said armature into the abnor mal position. Armature 68 is provided with insulation on its free end and oscillates between the screws 150 and 150 and being placed between the spring-

plates

100 and 100, said plates are brought into engagement with the screws 150 and 150 alternately, thus making a plurality of connections by the actuation of one armature.

It will be obvious that my invention is susceptible of many variations and modifications without departing from the principles herein set forth, and I do not limit myself to the details of construction and ar rangements of the parts herein illustrated and described.

The principal reason for transmitting messages by current pulses of alternatelyopposite direction is that polar instruments work better on a long line than do neutral instruments. Then preferred, the mainline relay of the receiver may be a neutral relay, and in such case the transmitter need not be so constructed as to reverse current polarity. Fig. l

It will be understood that the main-line relay of the receiver may be connected in series with the receiving relay of a duplex or quadruplex, thus enabling my receiver to operate in connection with such systems.
