telegraphic messages and seeks to provide a simple and effective arrangement which will operate with rapidity and certainty. K

The invention consists in the features of construction, combinations and arrangements of parts hereinafter set forth, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

In' the drawings:. Figure 1 is a front elevation of the 7 improved telegraphic printing apparatus. Fig. 2 is a plan view thereof. .Fig. 2 is a horizontal' section of Fig. 2 is a view in elevation of the printing hammer l magnet: Figs. 3 and 4 are detail sections-on lines 33 and 44 respectively of Fig. 1 illustrating the shifter mechanism for rotating the type wheel. Figs; '5, 5 and 5 are detail sections of parts taken on lines 5 5, aa and b-b respectively of Fig. .1. Fig. 6 is a front elevation of a modified form of the invention. Fig. 6 is a detail view of parts shown in Fig. 6. Fig. 7 is a diagram of the operating circuits for the form shown in Fig. Fig. 8 is a diagram of the operating circuits for the form shown in Fig. 6, and of the controlling electric selecting means.

The apparatus may be mounted upon any suitable frame, In the form shown, the frame comprises an I upright plate a, having a suitable base section or foot a. At the upper part of the frame are arranged apair of'uprights a offset in front of the frame plate, as shown Pivot screws b adjustably threaded through the uprights a? engage the cone-shaped ends of a horizontal shalt b which carries the type-carrier or wheel A.

core-piece 19 of soft metal. Each core 19 is arranged to slide within a tube 20 of brass or other suitable nonmagnetic material which extends through the spools of the solenoids and projects below the same to a consid- .erable extent;

wound that when energized the cores l jalllgthe racks 21 and 22 are drawn downwardly, and by properly energizingone or the other of said solenoids, the typewheel may be rotated in one or the other direction. Each solenoid core 19 (see Figs) rests upon the head of-stop-plunger 27, arranged within the tube or cylindel 20. The stem of the stop-plunger 27 extends through a cap 28 upon the end of the tube 20, and a spring 29 coiled about the stem eiftcnds between cap 7 28 and the head of the stop-plunger to yieldingly hold the latter in position. The position of the sto'pplun-' ger 27 and the tension of the spring 29 may be properly adjusted by rncans of the cap 28 and a thumb-nut 30, which are adjust-ably threaded upon the ends respectively of the tube 20 and the stem of the plunger. Thumb-nut 30 is ofcourse held into engagement with the cap-piece 28 by the spring 29. A lock-nut or stopmember 31, having a rounded lower end isthrcaded upon the extreme lower end of the stop-plunger stem, as shown. By this arrangement of yielding stop-plungers, which areheld against movement in one direction, butyield in opposite directions, the type wheel and rotating shifters therefor, may be held in central position, but are free to be actuated to rotate the type Wheel in opposite directions from normal against the resistance of one or the other of said stop-plungers. Moreover, the stop-plungers may .beladjusted to socurely', yet yieldingly'hold the type wheel in central position so that all back lash or lost play between the connected parts is taken up.

The rotating of the type wheel in each direction is variably arrested in one direction by a set of stop-arms G, 0 C and G, and-in the other direction by a set of stop-arms D D and D, which, in the form shown, are arranged respectively beneath the solenoids B, B and shiftable into the path of novcment of the stopmembers 31 upon the ends of the stop-plungers 27, to

i variably limit the movement of the corresponding shifters operated by the solenoids.

The separate sets of stop-arms and the operating de -wices'therefor, arc-alike except that they are oppositely arranged beneath the separate solenoids as shown.

65 circuits of the solenoids B and B.

Each set is arranged upon a suitable support 32, se- 1 contacts extends between the corresponding set of stopcured to the front face of the frame platelO. A pair of roelt-shafts 33 and 34 (see Figs. 3, 4 and 5) are journaled between forwardly extending lugs or brackets 35 5 upon the supports 32, and the stop-arms O, C are socured to the inner ends of the shafts, while the stoparms C C are secured to the inner ends of sleeves 36,

3 7 loosely mounted on the shafts but held against longitudinal-movement thereon by collars 38.

The stop-arms are oppositely arranged, that is to say, stop-arms C and 0 on shaft 33and sleeve 36, respectively, are normally held in front of the path of move ment of the abutment 31, with which they cooperate to arrest the movement of the corresponding shifter,

while the stop-arms C and Con shaft 34 and sleeve 37 lie inside of the path of abutment 20. Operating electro magnets E and E are arranged;upon the support. 32 above the shafts 33 and 34 and their armatures are carried upon arms d and d secured respec- J tively to and extending upwardly from the outer ends of the shaft 33 and the sleeve 36. Electro magnets E and E are arranged below the shaftsand their correspending armatures are mounted upon downwardly projecting arms d and d secured respectively to the outer ends of the shaft 34 and sleeve 37.-

The stop-arms are similarlyconstructed and each corresponds toupper and lower sections 39 and 39. The lower sections 39 have hub portions 40 secured to the corresponding operating shaft or sleeve, while the upper sections 39 of each arm has a laterally projecting stop-lug 41 at its upper end. The upper and lower sections are adjustably connected together by pin-and-slot connection 42, and screws 43 connected to cars 44 upon the upper section and threaded through cars 45 upon the lower section, serve to properly position'the stop-- lug 41 at the outer end of 'the stop-arm. The hubs of theseveral stop-arms are provided with downwardly extending ,lugs 46, between which .extend tension springs 47.

By selectively controlling the energizing circuits of the electro magnets E, E E and E the outer stoparms-'() and C may be shifted inwardly and the stoparms (3 and C shifted outwardly against the tension of springs 47, to bring the corresponding. stop-lugs 41 at their upper ends into the path of movement of the shifter operated by the solenoid B. The stop-lugs 41 are located at different distances below the ends of the shifter so as to variably arrest the rotation of the type wheel. i

The stops D, D D and Dand their operating magnets F, F F and F are similar in construction and arrangement and cooperate with the shifter operated by the solenoid 'B to variably limit the rotation of the type wheel in the opposite direction. -By the arrangement of the solenoids B and B, the corresponding,

\ shifters and sets of stops, the type wheel may be rotated in-opposite directions from normal to select any one of the longitudinal row of type thereon.

The energizing circuits of the solenoids'B and B are preferably controlled, each by the corresponding sets of stops or the operating circuits therefor For this purpose, pairs of normally open spring-contacts 48 and 49, mounted upon but insulated from lugs 50 on the supports 32 areinterposed respectively in the energizing Each pair of springtate the type wheel todcsired position.

arms so that when any one of them is shifted, the circuit through the corresponding solenoid is also closed. The contacts 48 and 49are provided with insulating strips 48 and 49 against which the stop-arms strike.

It is therefore only necessary to selectively control the.

energizing circuits of the stop-actuating magnets to ro- The lateral shift of the type carrier or wheel is effect.- ed in the form shown in Fig. 1 by a pair of electro magnets or solenoids G, G, arranged horizontally and in line as shown, and secured at their inner ends to a U- shaped piece 51 which, in turn is mounted upon an upright projection or lug 52 at the upper edge of the frame plate a. Lug 52 is offset toward the front and solenoids G, G are as shown, arranged in front of the racks and pinions by which the type wheel is rotated.

The solenoids G, G are alike and each comprises a spool 53, surrounded by a rectangle 54 of soft iron. A core-piece 55 common to both solenoids, is arranged to slide within theinner ends of a pair of cylinders or tubes 56 of brass or other suitable non-magnetic materialarrangodwithin the solenoid spools, as shown and projecting beyond the outer ends thereof. A shifter-arm 57 fixed to the central portion of the core 55 and pro-. jecting rearwardly and upwardly therefrom, has a slotted or forked end engaging a grooved collar 58 on the type wheel. By energizing one or the other of the solenoids G or G, the type wheel may be shifted laterally in opposite directions from normal.

The type wheel and the lateral shifter therefor, are

yieldingly held in central position between a pair of spring-held stops 59 (see Fig. 2), similar in all respects to the stop-plungers 27. These stops or stop-plungers 59, are arranged within, the tubes 56, engage the opposite ends of the shifting core 55, and are yieldingly held in position to center the type wheel in lateral direction by springs 60, coiled about they stems of the stop-plungers and extending between the heads thereof and the eap-pieces 61 threaded over the ends'of the tubes 56. Thumb-nuts 62 adjustably threaded upon the stems of the stop-plungers, engage the cap-pieces 61, limit the inward movement'of the plungersand hold them in normal position. By adjusting the-cap-pieces 61 and nuts 62, the positions of the stop-plungers 59 are pronerly adjusted to securely hold the type wheel in centralposition and take up all lost play or back lash between the parts.

The extent of lateral shift of the type wheel is limited .in one direction by the set of stops H, H and in'the opposite direction by the set of stops .T, J, the stops being arranged to'engage abutments 63 adjustably threaded uponthe projecting endsof the stem of the stop-plungers 59. Both sets of stops and the controlling devices I therefor, are similar in construction and mounted upon supporting plates 64, which are fixed to the upper, front portion of the frame plate a. Stop H is fixed to the support 64, but stop H is in the form of a shiftable arm. The latter is provided with a laterally projecting stop-lug 65 on'its end normally out of the pathof the adjacent abutment 63,.but arranged to shift into position between the abutment and the stop H, Stoparm H is mounted upon a rock-shaft 66,.journaled between a pair of brackets or lugs 66 on the support 64, and provided with ,a laterally projecting arm 65 to mounted upon but insulated .plate 64 in the path of movement of the stop-arm H,

which the armature of the operating magnet K is secured. Magnet-K is mounted as shown uponthe support 64.

A pair of normally open sp ng contacts 67 are so as to be shifted to closed position when the electro magnet K is energized. These contacts are interposed in the energizing circuit of the adjacent solenoid G,

whihserves to shift the type laterally.

The stops. J,- J

sitely arranged to variably arrest the lateral shift of the type wheel in the other direction. Stop-arm J is arranged to engage and close a pairof normally open spring-contacts 68 interposed in the energizing circuit The contacts'67 and 68 are provided with insulating pieces 69- against which 'the of the solenoid G.

stoparms H and J strike.

.By closing the energizing circuit of one or the other v of the solenoidsG or G, the type wheel may be shifted laterall mesa, ergized, either the stop H or J is operated, the circuit through the adjacent solenoid G or G is closed and the type wheel is shifted laterally as before in one or the other direction, but is arrested by the engagement of.

one of the abu'tments 63 with the stop-lug 65 upon .eithei" one of the stop-arms H or J. By this means, the type wheel may be quickly shifted endwise in opposite directions from normal audits shift is variably arrested by the stops to bring any one of the-lateral rows of type upon the wheel to-printing position.

At the'tdp of the' fiaine plate a is arranged a horizon-;

tal platform or top plate 70, which extends rearwards,

' as shown in Fig. 3. An upright portion 71, at the extrcmerear of the platform 70, carries the printing ham mer. M and the operating magnet N therefor. The

printinghammei M is upon the arm of a bell crank 72, arranged. to swing in a horizontal plan upon a pivot- 73., which is carried upon' a horizontal support 74,

V projecting forwardly from the upright 71.

The actuating magnetN is preferably in the form of a solenoid and is carried by horizontally arranged U-shaped support fixed to the outer end of the up right 71 andforwardly projecting therefrom. w This. solenoid co'mprisesa spool 75.sur.-.undedlby arectam gular piece 76 of soft iron and provided with a shifting core-piece 77. The inner end of the core-piece or 50 shifter'77 is provided with a fixed collar 78 and a.

loose collar 79, between which extends the'forked end of the short arm of the bell crank" 72. Collar 79 is yieldingly held in position by a coiled spring 80 which extends betweenv the collar and a nut '81 adjustably threaded upon the end of-thezshifter 77. A lock nutor stop-member 82, having a rounded outer end is threaded upon the extreme end of the shifter 77 and holds nut 81 in adjusted positionfyrl stop screw 83 isadjustably threaded through a stud 84,

projecting forwardly from the upright 71 and. is

1 ranged in the path of the stop-member 82.

when the solenoid N is energized, the core-piece or shifter 77 is actuated to move the hammer M toward the type wheel A. The stop-member 82 upoii the 65 shifter is arranged to engage the stop-screw 83, before mm the supporting v and the operating magnet L for thestop-arm'J, are similarly constructed but are oppoin enebr'the other direction until arrested by H or J. If either of the magnets K or L is enthe hammer. strikes the wheel. The hammer is however, not arrested but the spring-held collar 79 permits it to continue its movement under the' influence of the momentum acquireduntil the blow upon the ,type at the printing point is struck to effect theimpression thereof upon the paper. The blow is thereby rendered sharp and quick. 7 Each of the'shifters of the solenoids B, B, which rotate the type wheel, is also'arranged to close the energiz'ing circuit of the'solenoid N whichoperate's the printing hammer. For this purpose, a pair of normally open spring-contacts 85 (see Fig pl) are mounted upon. an arm 86, but are insulated therefrom as shown. Arm 86 is pivoted to the lug 50 on the supporting plate 32. A spring 87 extending between the end of. the arm 86 and the plate 32 holds the free ends of the contacts into engagement with the stop-member 31 on the lower end of the shifter of the solenoid B and above the set of stops C, C and C. Whenever anyone of the latter and the shifter of solenoid are operated, the conta efs 85 and arm' 86 are swung about the pivot of the arm until arrested by the engagement of the free ends of the contacts with the selected stop. The contacts are then brought into engagement to close theenergizing'circiiit of the solenoid N and to operate the printing hammer M. 'lhefrodends of the contacts 85 are provided with insulating strips 88 with which the stop-members 31 on the shifter of solenoid Bv and the stop-lugs 41 of the arms C, G etc. engage. I

A pair of contacts 89 similar in construction and arrangement are interposed in the circuit of solenoid- .'N and cooperate iii a similar manner with the shifter of solenoid B and the set of stops D", D, D and D. A pair of normally closed spring-contacts 90 (see Figs. 2 and 2") are mounted upon but insulated from the rectangular piece 76 of the solenoid N. A bell crank 91 is pivotally connected toa bracket 92 upon the outer end of rectangular piece 76. One end of the bell crank is forked and extends between a pair of collars'93, adjustably threaded upon the outer end of the shifting mire-piece 77, and its opposite end is arranged to engage one of the spring-contacts 90, and break the engagement thereof, wheriever the solenoid is energized.

(ontact-springs 90 are interposed in the energizing 11o circuit leading to the operating magnets and solenoids,

so that as soon as theimpression of the selected ty'pe is made, the circuit is broken and the several magnets and solenoids are denergized to permit the return of the shifted parts to normal position. The type wheel is quicklyreturned to normal by the springfactuated stop-plungers 27 and 59'.

i The paper upon which the messages-are recorded is carried in the rear of the type wheel A, and intermediate the same and the printing hammer M, upona carriage 0 (indicated in dotted lines in Fig. it) arranged to slide transversely upon'the plat-form 70.. -,The papera carriage may be of any suitable construction, and any suitable meansmay be employed for shifting the same laterally or in' letter-space direction'.step-by-step' at printing hammer actuating each operation of the printing mechanism. So too, the

paper carriage may be provided with any suitable form of paper feed mechanism to properly fonn' the spaces between the lines oi printed matter.

It will be obsenved that the mechanism for rotating 186 the. pathof the snm-nn-mla-r 63', and moves contacts 68. A circuit is then closed from battery by power wire 9th conductor 97, contacts (i8, conductor '98 and branch 2 through the solenoid G, and back to and laterally shifting the type wheel, is entirely in front of the wheel and in front of the supporting platform 70, and that the printing hanuner is mounted above. the path of movement of the carriage upon the upright 7i at the rear of the platform. Ample space is thus provided for the laterally shift-able paper carriage. Moreover, the paper I (see Fig. 3) is held in v rtical position at the rear of thetype wheel and in front of the horizontally arranged printing hammer, so that the message may be (amveniently read as soon as it is recorded by any one in front of the machine.

I A diagram of the operating circuits is illustrated in Fig. 7, The several operating magnets and solenoids derive current from a local battery 94 and are connect ed on one side thereto by a. series of branches and a common return conductor 95, indicatethby heavy lines in .the diagrmn.- The operating magnets and solenoids in Fig. 8 and-will be hereinafter described.

A power wire or conductor 96 leadsffrom the local baiteiy 94 to'the electric selector means and back tln'ough'mie of the branches and one of .the magnetsor solenoids in accordance with the operationof the sclec tor means. The normally closed spring-coniacis90 are.

interposed .in the g-o nluctor 96 as shown. The circuit is first closedtln'ough one of branches 2,-3-or 4, lcadin respectively to'the solenoids (if, magnet l,, magn t K and solenoid G. if the circuit is closed directly by branch .I into the solenoid (i. thetype-wheel is shifted to theleft until arrested by the engagement of the stopmember 615, with the stop J. lly closing thecircuitf through branch 2,-and magnet I, stop I is shifted into into engagement.

battery through tin-return conductor 95'; 'lhetypewheel is then shifted to the left but is arrested by the engagement of the stop-inemlwr with the stopJ, which is then in front. of the stop .l. -'lhe circuit through eonductoi-2. thus not only controls the operation of'stop magnet all. but also controls the operation of the shifter in a similar mannen'tho typev magnet or solenoid fl, wheel may be shifted to different. extents to the right. or-unt ii the stop-nn-mher 63 engages either the stop 11 or the sto l I, by closing thocircu it through the branch I, or branch 4 to engage the magnet K or-thqsolenoid GP When magnet K is operated to shift stop H into the path of the stopanembero3,contacts G7 are brought into engagement and a circuit may be traced from batair by conductors 9th 99, and Hit) to (ohm-1.467, thence by conductor 'IOl to solenoid (1 and back to battery by return wire 5. in this way, the type-wheel may be shifted one or two steps to the right or left, to bring any one of thefour rows of type thereon in line ivith the printing poinnand to bring any oneof four letters in the longit niinalrow of typebeneath the printing lntmnna' to the printing point. If one of the four type in this row is desired, the hannner M is operated direct-i y after the sideshift of the Wheel, by closing the circuit through the branch 15 and solenoid N,- to effect the impression of the selected type upon paper. If one of the type to be brought to the printing point is in one of the other longitudinal rows, the type, wheel must be rotated after the side shift, by closing the energizing circuit through one of the branches b.'6, 7, 8, 9, l0, 1], l2 and through one of the stop-actuating magnets E, F E, E, F, F-,'F or F which are respectively connected to the several branches on one side and to the re urn conductor 95 upon the other Branches 5, 6, 7, audit also control solenoid B, since whenever one oi the set of magnets F, F F and F" is energized, one of the stops D, D'-, D or D is shifted into the path of the stopmember 3i. to arrest the movement of the shifter actuated by solenoid 13, the shifted stop also movescontact 49 into engagement and closes the energizing circuit of'solenoid B as follows, from battely by power wire 96, conductor 10l,contact's 49, conductor 102,

through the coil of solenoid B and back to battery by relurnieondu(rt-01:95. So that the type wheel is rotated in one direction and variably arrested to bring the selected type to theprinting point. In a similar manner magnets I 15", If) and E operate to shift any one of the set of stops (3, C or G into the path of the corresponding stop-member 31 to limit the movement of the shifter of solenoid B and shift contacts 48 into engaigement to close the circuit through solenoid B, as follows;---from power wire 96, conductors 99 and 103, contacts -48, conductor 104 to the coil of solenoid 13 and bachto the battery by return conductor 95. By

this means, the type wheels may be? variably rotated in the oppositedirection.

fly combining the lateral and rotary movement of 'the type wheel, any character thereon may be brought to the printing point; When solenoid B is energized contacts 89 are brought into engagement and a. current may be traced from power wire 96, by conductors 105, contacts 89, conductor 1 06 and branch conductor 15 to the coil of sele oid N and back to battery by return 1 mnductor 95, so that the printing hammer M is shifted toeffectthein'iprcssionoftheselected type. Similarly} the shifter of solenoid -ll moves contacts 85 into engagement-to close the printinghammercircuit as follows:- from power wire So, by coininclors 99 and 107 to contacts 85, conductor 108 and branch conductoi 13 thronghthe coil of solenoidN as before. In this form.

the type wheel may be shifted laterally to the right, or

left. one or two steps, to bringany one of four transverse rows of type in line with the printing hanuner, and retated 'inone or the other direction, one. two, three or four steps to bring any one of eight longitudinal rows of type to the printing point, 'fhelongitmlinal row of t e in line with the-hammer ma. also be utilized 'so 7 that the type wheel may be ,provided with thirty-six characters in all. Tho-number of stops for variably arresting the rotation and lateral shift of the type wheel, may of course be varied as desiredfsb that more or less characters may be employed. Whenever the printing hammer solenoid N is energized, contacts 90 are disena 'aqed bv the. shift of hell crank 72 and the )(IWtT circuit is broken atthis point so that all parts may quick-l y return to normal position and are ready to record the sin-(routing character. I

In theform shown in Fig'. 6, the ,type wheel N is similarly mounted upon a' shaft 1) at the upper portion of the frameplate a, and is arranged to rotate with the shaft and shift laterally thereon. The rotation of the type wheel in opposite directions is effected by a horizpntal shifter arm-109, carried upon a pivot 110 at the upper end of a standard 111. Standard 111 is mounted as shown, upon a horizontal supporting plate 112 fixed to the upright frame plate A. A toothed segment 113 is mounted upon a short rock shaft 114 carried between the upright a and a; second upright 11 upon the frame. Segment 113 meshes with the teeth of a pinion 115 upon the typewheel shaft b and is connected by a sides of the standard 111' and the armatures of these magnets are fixed to the shifter 109 on opposite sides;

of its 'pivot. By'energizing one or the other of said magnets, the type wheel maybe rotated in one or the other direction. The type wheel A is held in normal central position by a pair of stop-plungers 117, arranged within vertical guide cylinders or tubes 118 mounted upon the support 112. The stems of the stop-plungers extend through plugs 119 adjustablythreaded into the upperends of the tubes 118, and also extend loosely through slots in the shifter-arm 109. Stop nuts 120 are adjustably threaded upon the upper ends of the stems of the stop-plungers and engage the upper edge of, the shifter-arm. Lock-nuts 121 hold the stop-nuts 120 in place. The stop-plungers, shifter-arm and typewheel are yieldingly' held in place against bottom plugs 119 in cylinders 118 by springs 122, coiled about the stems of the stop-plungers 117 and extending between'the headsthereof and the plugs 119. By ad.

justing the latter, springs 122 may be placed under proper ten'sion.- By properly adjusting the stop-nuts 120, all loose playlor back lash between the parts may'b'e taken up and tho shifter-arm 109 and typewheel A accurately held in central position. The sets of stops C, C", l and C and the stops D, D'-', D and D for variably limiting the extent of rotation of the type wheel in either direction, are entirely similar in construction and mode of operation to those employedupon the form shown in Fig. 1, and are. arranged on opposite sides of the projecting endof the shifter arm 10.) to limit its movement in either direction. The contacts 48, arranged to be closed by anyone of the stops-Q, O, C or (1* are interposed in the circuit of magnet li and contacts 49 controlled by the stops D,

I), 1) and D are interposed in the circuit of magnet 13. In this form however, additional stationary stops and D" are fixed to the supports 32, respectively, below and aboye the sets of movable stops and by clos-' in g the energi zing'circuits by either .niagnet B or magnet 15, independently of the shiftable stops, the arm 109 may be moved in one or the other directioninto ongagement with one or the other,of the stationary stops C or D 1 The pairs of contacts 85 and $9, for closing the printing hammer circuit, are held by the springs 87,

a into engagement with the end of the shifterarm 109,

so that this circuit is closed whenever the arm 'is moved in oither'direction.

The printing hamnier, operating means therefor and paper-carrying means in rear of the type wheel (not shown in Fig. ,6) is entirely similar in construction and arrangement to that'already described. In this form.

the type wheel maybe rotated in one or the other direction, one, two, three, four or five steps, and since the row of type inline with the printing hammer may be utilized, the type wheel. may be provided with eleven longitudinal rows of typ'e. The type wheel in this form, is shifted laterally in one direction only. Shifter 55and solenoid G for moving the type wheel laterally toward the left, are entirely similar in construction and arrangement to that previously described, except that the type wheel and shifter are held against movement toward the right from hormal position by a stop-screw 122 adjustably threaded through a lug 123 on the bracket 51. Stops J, J for limiting the shift ofthe type wheel to .the left are similar to those previously described.

An additional. movable stop-arm J 2 is provided, having its stop lug in advance of that on thestop-arm J. This stop-arm is secured to a shaft 66 journaled in lugs 66 and 67 and extending through a slot in the stop-arm J. The armature of a magnet L is fixed to an arm 68 on the shaft 66 so that the stop J 2 is shifted into the'path of the stop-member 63 when magnet L is energized. Stop-arms J and J 2 are arranged to close the energizing circuit of the solenoid G by shifting the contacts 08 into engagement in the manner previously described. By this means, the type wheel may be shifted to the left, one, twoor three steps, and as the' transverse row of type in line with the printing hammer may be utilized, the type wheel may have four transverse rows of type as shown. As there are eleven longitudinal .rows, forty-four characters may be employed, any one of which may be broughtto the printing point by properly combining the lateral and rotary mi'ivements of the type wheel.

A diagram of the operating circuits is illustrated in Fig. 8. As before, the current is derivcd'from a local battery 94 to which the several operating solenoids and magnets are connected on one side by the branched return conductor 95 indicated by heavy lines. On the other side, the several solenoids and magnets are connected to a set of branches, (numbered 2 to 15 inclusive) which are controlled by suitable electric selectivemeans. A power wire 96 leads from the battery to the solenoid G is closed, the type wheel is shifted to the left until stop-n1ember 63 engages the fixed stop J and the fourth transverse row of type is brought to the printing point. If the circuit is closed through branch 3 or 4'and magnet L or L, either one of the stops J and J is shifted into the path of stop-member 03. At the same time contacts (58 are brought into engagement and the circuit through the solenoid G is closed, as previously described, from power wire 90, by \conductor 07, contacts (38 conductor 98.and branch conductor 2, and the type wheel is shifted to the left tobring either the second or third'transverse row of type in line with the printing hammer. After the side shift of the type wheel, it is rotated to bring the desired type to the printing point by closing the energizing circu it through one of ten of the branches, number 5 to 14 inclusive. The branch circuits numbered 5 to 12 as before, are arranged to selectively operate the sets of stops D, D D and D and the set of stops E, E", n and E which, when or four steps to bring the selected type to the printing point. Branches 13 and 1.4 are arranged to close the circuit directly through the type wheel rotating mag nets B and B (without first actuating any oithe movable. stops) so that the wheel may be rotated in one or the other direction five. steps until arrested by the engagement of the shifter-arm 109 with one or the other of the fixed stops C or D". As before, the shifter mechanism for rotating the type wheel cooperates, when actu ated, with the contacts 85 or 89 to close the hammer operating circuit through the solenoid N. One of the type on wheel A lies at the printing point, and to effect the im r ssion of the type, the circuit is closed through branch 15 and directly through the hammer-actuating solenoid N. If the type to be selected lies in the longitudinal row in line with the hammer, the wheel is first shifted laterally to bring the same .to the printing point and the circuit is then closed directly through branch 15 and solenoid N to operate the printing hammer without rotating the type wheel. If the character is in the transverse row of type in line with the printing point, the wheel is rotated to the proper extent, with-' out first shifting the same endwise and the hammer actuating circuit is automatically closed as before by the shifter 109. The other characters must be brought to the printing point by continuing the laterally and retary movements. Thus one character may be printed without shifting the type wheel at all, thirteen by variably shifting the wheel with one movement only and the remainder of the forty-four characters by combining the two variable movements in different directions. The variable shifts moreover, are not step-by-step but the type wheel is quickly moved.by a single throw in one and the other direction. Moreover, no time is lost in restoring the parts to normal position, since as soon as the printing hammer is actuated the contacts 90 are disengaged to open the circuit through the several oper-' ating magnets and all shifted parts are instantly returned to normal position by their restoring springs. The type Wheel may thus be operated with great rapidity and certainty to record the succeeding characters of the message.

Various means may be employed to selectively control the flow of current through the several br-ahch con ductors 1 to 15 inclusive. The selective means in turn is controlled by the line circuit over which the mes sages are transmitted, the various characters being represented by variably modifying the circuit impulses over the line in keeping with a suitable code.

In Fig. 7 is illustrated one arrangement of electric selector means which may be employed. In this arrangement, the line circuit. 125 extendsfrom the transmitting station, through a set of relays 126, at the receiving station, and then to ground. These relays respond differently to the varied line impulses, for example, to strong positive and negative and weak positive and negative impulses respectively, as indicated.

The armatures of the first aud second relays which re spond to the strong impulses are connected to battery 94 by a conductor 127, and the armatures of the third and fourth relays are connected to the back contacts of the first and second relays by conductors 128. A set of conductors 130 are connected to the front contacts of the several relays and are selectively connected to the battery or other source of power by the operation of the relays 126 in response to varied line impulses. The set of conductors 130 are connected to a set of transfer switches 131, to the back contacts of which a set of branch conductors 132 are connected, so that the couductors 1.30 are normallyconnected at this point at the branches 132. A relay 133 having oppositely wound coils orcoil sections, is arranged to actuate the transfer switches 131, at the end of the first line impulse to shift. the connection of the conductors 130 from the branch conductors 132 to a set of conductors 134, which are connected to the first contacts of the switches .131. In each of the branch conductors 132 is arranged a relay .135, and each relay is arranged to actuate a switcharm 136 and a second locking switclearm 137. I In this arrangement of selecting means, each character is represented by three modified lineimpnlses. At the first line impulse, the circuit may be traced from battery 94, by conductor ]27 to the armature of one of the line relays 126 (operated in accordance with the character of the line impulse) to one of the conductors 130, and one of the branches 132 and the corresponding relay 135, thence by a conductor 138 and a conductor 139 (common to all of the relays 135) through one of the coils of transfer switch relay 133 and back to battery by return wire 95. Oneof the switches 137 then actuated, closes a circuit from battery wire 96. conductors 140, 141, switch 137. conductor 142, through the coil of the magnet 1335. which has been energized and bya common conductor 143 through the. opposite coil of transfer.

switch relay 133 and back by return wire 95. The shifted switches 136 and 137 are thus locked .in shifted position after the first .lineimpulse has ceased The. circuit is closed. through the oppositely wound coils of transfer switch relay 133 beforc it can operate, and as the coils balance each other. the swift (hes 131. are not moved until the essation of the first line impulse opens the circuit through the branch coinluctor 132 and one of the coils of the relay 1.33. Switches 131 are then shifted to change the connection of the eonductors 130 from the bran hes 132 to the set of condur'tors 13-1, and the transfer switches, together with the selected switches me and 137 are lot-lied in shifted position. J

The set of switches 131i. selectively control the branch circuits 1,2. 21 and -1 leading to the operating path of the printing nn-chanism. The selected switch 136. closes a circuit from battery wire 96. conductors HO and 141. selected switch 136 and one of the branches 1. 2. 3 or 4 1o effeet the side shift of the type wheel. The form of printing apparatus shown in Figs. 6 and 7 does not utilize branch- 1. controlledbythe first relay .135. so hat if the wheel is not to be shifted laterally, the first line impulse selects this relay and merely serves to operate the transfer switches 131.

The set of conductors 121-1 lead to a seconds-e1 of transfer switches 1 14 to the back contacts of which a set of branch condncton 116 are conne ted. v.\ relay 116 I conductors 5 to inclusive, which lead to the operat switch 153.

' ing switch 131, conductor 134 and switch. 144, to one of having oppositely wound coils or coil sections, is ar- 1 ranged to shift the switches 144 at the cessation of the second line impulse to change the connections of the conductors 134 from branch conductors 145 to the branches 147 (three in nuinber) which are connected to the front contacts of the transfer switches 143. In each of the branch conductors 1.45 is arranged a magnet 148, each controlling a set of switches. The first n1ag net 148 is arranged to operate the set of switches 149, and the second, third and fourth magnets respectively operate the sets of switches 150, 151, and 152. There are three switches as shown in each of these sets and they control the flow of current throngh the branch ing parts for effecting the rotation of the type wheel and the independent operation of the printing hammer. Each magnet is also arranged to operate a locking At the second line impulse, the local operating cir cuit is closed as follows: from battery 94 by conductor 127, to the armature of one of the line relays 126, thence by one of the conductors 130, the correspondt'he branch conductors 145, through the coil of the corand B- responding magnet 148, conductor 154 and common conductor 155 through one of the coils of transfer switch relay 146, and by return conductor 96 to battery. One of the sets of switc ies 149, 150, 151 or 152 corresponding to the selected magnet 1.48 is then shifted and locked in shifted position by the operation ofthecorresponding locking switch 153. The latter closes a circuit as follows: from battery 'wire 96 by commonconductor 157, conductor 158, the selected locking switch 153, conductor 159 through the coil ofthe selected magnet 148, by conductor 160, and common conductor 161 through the opposite coil of transfer switch relay and back to battery as before by conductor 95. The opposite coils of transfer switch relay Htiare thus both energized, and, as they balance each other, the relay is not actuated until the cessation'of the secbnd line impulse At this time, the circuit through one of the coils of relay 146 is opened and transfer switches 144 are actuated to shift the connection of the conductors 134, from the set of branches 145 to the set of branches 147. I The locking, circuit controlled by the shifted locking switch 153 is held however, in closed condition through the selected magnet 1.48 and through one of the coils of relay 146, so that one of the sets'of switches 149, 150, 151 and 152, and the set of transfer switches 144 are shifted and locked in shifted position by thesecond line impulse of the signal.

Each one of the three branch conductors 147 is connected as shown to one of the three switches in each, of thesets 149, 150, 151 and 152. As stated, each character is represented by three line impulses. At the third line impulse, the local circuit is closed as follows: from battery 9 by conductor 127, the armature of one of the line relays l2ti,'one. of the conductors 130, through the corresponding switch 131, conductor 134 and switch 144 to'one vof the branch conductors 147, thence to one of the switches in that. sep'l 49, 150, 151 or 152, which have been previously selected andshifted by the second line impulse, and

thenee to one oi the branches 5 to 15 inclusive, and

through the operating Viously described.

As above stated, branches 5 to 12 inclusive, .control the stop-actuating magnets-which effect the variable rotation of the type wheel. Branches 13 and 14 directly control the type wheel rotating magnets B without iirst operating the one of the stop magnets. If it is not necessary to rotate the wheel to bring the desired type to the printing point, the circuit is directly closed through branch 15 and hammer actuating magnet N. g

The controlling circuit through the selecting means parts of the machine, as preas well as through the printing apparatus, is broken as soon as the printing hammer is actuated to disengage the contacts 90 in battery wire 96, and all parts are immediately returned to normal position, and are ready to receive the succeeding signal and record the character corresponding thereto. This same selector" means could be employed to control the operation through the set of branches which govern the operation of the printing mechanism diagrammatically illustrated in Fig; I. The controlling branch conductors are correspondingly numbered in Figs. 7 and S.

The particular electric selector means set forth forms no part of the present invention, and other arrangements. may be employed for selectively control-'- ling the flow of current through the set of conductors leading to the operating parts of the printing mechanism. i

It is obvious that numerous changes may be,made in the details of structure and arrangomentof parts without departure from the essentials of the invention. For example, the type-wheel or carrier may be segmental in form, if desired.
