1 0 an w/wm it may conccm Be itknown that I, Gnorcn S. CONGER, a citizen of the United States, residing at New York city, New York, have invented certain new and useful Improvements in Printinglelegraph Receivers, of which the following is a clear, full, and exact description.

This invention relates to a printing-telegraph receiving apparatus which is adapted to receive electrical messages and present the same upon a printed page, and is of the general character as shown in the patent to Landfear #765,978, dated July 26, 1904. As is usual in such machines, my apparatus is arranged to be controlled by a transmitting circuit and comprises the several fcatureS of neans for holding a sheet of paper, I a rotatable type-wheel, and means for moving said type-wheel and paper sheet transversely of one another for letter-spacing, together with means for feeding the paper longitiulinally of said type-Wheel for linespacing.

.lviore particularly the present improvement consists in providing an individual source of power for actuating each one of the above-named mechanisms ofthe apparatus and in having each oneof said actuators under the immediate control of the transmitting circuit for positively operating their respective mechanisms, whereby all of the operating parts of the machine are made quiclny responsive to themessages sent. By this arrangement, a suitable construction of which will be described at length in the following specification, I have provided a printing telegraph receiver which will operate at a much higher rate of speed and with far greater accuracy in' presenting messages, than the machines at present in My invention consists further in several improved details of construction as will be hereinafter described, as well as the general combination of parts making up the com-- plete machine, and I am aware that many modifications and equivalent arrangements may be employed without departing from the full scope of my invention.

In the drawings which show the preferred embodiment of my invention, Figure 1 is a front elevation of the entire machine; Fig. 2 is a sectional plan of the same through line of Fig. 1; Fig. 3 is it R ft-hand end view of the machine; at is a right-hand end view; Fig. 5' is a transverse section along line '55 of Fig. 1 looking in the direction of the, arrow; Fig. 6 is a transverse section. along line 6-6 of Fig. 1 lookng in the direction of the arrow; Fig. 7 1s a sectional detail of the type-Wheel; Figs. 8 and 8 are further sectional details of said type-wheel through line 88 and 8*-8 re spectively of Fig. 7; Fig. 9 is a detail of the feeding rack; Fig. 10 is a sectional detail of one end of the type-Wheel shaft showing tension means thereon; Fig. 11 is a sectional detail of the circuit-closer for the winding circuit; Fig. 12 is an end view of said circuit-closer; Fig. 18 is a detail of the paper-feeding pawl mechanism; Fig. 1 is a detail perspective of the type-wheel guard; Fig.7'15 is a diagrammatic view of the electromagnetic actuators for the dit- E's-rent parts of the machine, together with the energizing circuits therefor; and Fig. 16 is a detail section through line 16- 16 of Fig. 10 showing a contour of the torsion spring for the type-wheel shaft.

Referring more particularly to the draw ings, the frame of the receiving instrument consists of the base 1 and end plates 2 and 3. Mounted in suitable hearings in the upper portion of the end plates is the typew heel shaft 4 carrying a type-wheel 5 keyed thereto for rotation therewith but slidably mounted on said shaft as shownv so as to be moved transversely back and forth along the same. -The type-wheel 5 is preferably of the usual construction having fixed to its periphery the characters to be printed, and the particular manner preferred by me for mounting this type-Wheel 5on its shaft 4 sov as to be freely slidalole thereon and yet preserve a definite and fixed printing point for each one of its characters is shown in Figs. 7, 8 and 8 Referring to said figures it will be seen that the type wheel has adjacent to its hub 22 a separate collar or follower 24 connected to said hub 22 by a coil spring 2-6 tending to rotatesaid type-wheel and collar in opposite directions relative to said shaft 1. The typewheel in'its, keyed connection to the shaft v whereh i it also has a. free play on the shaft -1l-. Since the type-wheel huh is connected to the follower 24 by coil spring 26, it will be obvious that the separable parts are thus held against the opposite sides of their re Sportive slots .23 and so as to maintain a fixed relation to the shaft eland yet permit of an easy sliding movement thereon, due to the wide slots.

The type-wheclshaft i is provided with the usual escapenlent mechanism at one end thereof for controlling its rotation, shown more particularly in Figs. 1 and Jr. This escapeinent mechanismcomprises an escape wheel 7 fixed to the shaft and released step hr step by the double hooked arm 8. which Forms the armature of polarized magnets N. In the present embodiment these polarized magnets are operated in the usual, manner by the transmitting circuit 96 as shown in Fig. 15, which transmitting circuit may have an alternating current passing therethrough whose numheroi' alternate impulsestor fixing the ty iewheel shaft in dili'crcnt positions is contr lled by a transmitter (not shown}. The means for sending alternate impulses through said transmittingcircuit is indicated diapu'anuuatically in Fig. 15 hr the circuit changer 9S).

Tg/pearlrrrd almffi actuating 1iwc'/mriiam.- The means for creating a constant tension on the t vpc wheel shaft 4 tending to rotate the same consist of a. coiled spring (3 (see Figs. 1 and 1%)). connected at one end to the shaft 4 through escape pinion 7. and

at its other end to a pinion 57 loosely mounted on said shaft 4, as shown in Fig.

10 The torsion spring; (3 is kept in a wound mndition tending at all times to rotate the shaft l by means of a large spur gear 58 (sec lfigs. 1 and t) engaging with the pinion 57, said gear heing intermittently driven in the same direction by a pawlrarrier 32 loosely mounted on shaft 60 and having a pawl (31 for engaging a ratcl'ict wlieel 59 connected to said spur gear 58. A s 'iring 6? tends to keep the pawl (31 in engagement with said. ratchet 5E), and the pawl-carrier llit is oscillated h means of an arm (it fixed to shaft 65, said shaft also havingiixcd thereon an armature (it; which is attracted hy the magnet Z which r'orins the source of power or the electromagnetic actuator for the type-Wheel aha l't winding mechanism (see Fig. 2). A spring 6? moves the arm i'al for withdrawing thy-armature ill, and a stop (38 is provided to limit said increment. lfrlpring detent il prevents retrogri'ulc rotation of spur gear 58.

The elcctroouagnetic actuator Z is, energlaed intern)il'tently by a circuit 101:), 10%, al'uiwn dlap rainiuatically in Fig. '15. An intermittent circuit-chisel" 100 for closingthis winding circuit with the necessary frequency is mounted on one end of the typewheel shaft 4:, as shown in Fig. Said cir cuit cioser comprises the conducting portion 101 and an insulating hralte 102, upon which

bear brushes

101, 102, respectively, connected in said circuit 103. The winding circuit receives its current from any suitable source, such as battery B shown in ll ig. 153, and it will. be clear that at each rotation of the type-wheel shaft 4 the circuit is closed by the circuit-closer 100 to energize magnet Z and consequently wind up spring 6. The arrangement is such that the spring wound up at each rotation of the Slll'lft at least as much as it loses by said rotation, so that the tension upon the same is substantially constant, although prcferal'ily the hat-- tery B should he of such strength as to be ineffectual for operating the armature (56 when said spring is wound tigl'it. The coils ofthc'torsion spring (3 surrounding shaft 4 are angular as shown in Fig. 16, instead of lacing circular, so that said spring when heing wound by its pinion 5?, will not hucldo and cramp. The oils are preferably shown as having been wound on av square arhor, although thei might equally he wound on a live-shied, six-sided or smewsided arhor, the essential requirement heinothat they should not he circular. l have found that such a torsion spring may he used without the necessity of an outer covering shield for keeping it in place, for with angular coils as'thus shown the sprinp willdistriluite its tension throughout its length without hurkling.

Lettcrepar ing mar/main:. I or spacing: letters in each horizontal line upon the printed page I prefer to more the typewheel transversely of the shoot of [)flIIOXJfiIH'l. for this purpose I mount a type-wheel car-- rier 27 slidahly upon an angular shaft 538 as shown in Fig. 5. This type-wheel carrier isq n'ovided with. forltedarms 31 and 323 (a .n Fig. 1) engaging grooved huh portions: and 34 at each side of the typeovhecl 53, as shown in Figs. 1 and 7. The sides oil." the forked arms 3]. and 32 are cut awa as; shown 1n Fig. 5, so as not to rest against the hub of the typenvhecl 5, thus avoii'ling an trict1on to prevent its free rotation, and the typewheel carrier is further supported h'v a horizontal extension 25) running withiii a grooved rack 30 as shown in Fla: 51. This construction provides a two-point. slidahlc bearlngfor said type-wheel carrier to prevent any tendency of the same to rest against the type-wheel and check its free rotation. Upwardly extending arms are also. provided on the type-wheel carrier 27, and mounted in the ends of these arms is the usual ink-roller 36 adapted to bear against the type-wheel 5. l ivotally mounted at 40 upon a lower-extension 39' of the type-wheel I A l is attracted.- by magnets Y which form the source of power or electro-magnetic actuator for operating the letter-spacing; mechanism. The springlll is provided to return the lever 44 after eachattraction; and a throw-oft dog is provided to disengage the pawl 43 from rack 42 after each forward movement to allow said rack to return under the forceof a spring 56 connected thereto as shown in Fig. 2. An abutment 112 is also provided to limit the rearward movement of said lever 44. It will be ob vions that at each forward movement of the feed rack 42 the type-wheel carrier 2'! iscarried a step along its support. by the engagement of one of its pawls, such as 38; with the rack 42, and is maintained in it's for- Ward position by the engagement of the other pawl 37 with the stationary rack 41.

Springs 73 and 72asshown in Fig. l'tend to keep the respective pawls 37 and 38' in engagement with the feed racks. In order to prevent any overthrow of'the type-Wheel carrier 2'? .under the forward impulse of said feed rack 42 a checking device is provided as shown more clearly in Figs. 1 and 9.

This checking device preferably consists of a toothed bar 79 supported on side arms 93 fixed to a rocking shaft 93, which shaft is oscillated for operating the type -wheel return mechanism, as will. be hereinafter described. The outside. pawl 38 of the type wheel carrier is provided with a lateral extension 88 wllich, when said pawl rides upwardly over the teeth o f'the. stationary rack 11, is thrown behind one of the teeth 7 9 on the checkingbar it, as shown in Fig. L. The teeth 79" "of the chec lcing bar are located slightly forward of corresponding teeth on rack 41 and act to check the forward advance of the pawl 38 but permit it to drop into the notch of the next succeeding tooth on rack 4;2. Thus it will be seen that with the oscillation of lever 44 by-tl1eenergiza tion of magnet Y thefeed racks movezthe.

typewheel' carrier and. type-wheel step by step transversely along their supports to the right of the machine, and by positively checking any overthrow, the type -Wheel prints acurately andwith even spacing bes. A. return arm. 69 impelled P Fl tends to returnthe carrier at -5 to the left side of the machine. The :whcel is provided with a guard 36' (as shown in 11%) mounted on-the carrier 2? (asshown in Fig.- 5), which cover the type-Wheel adjacent its print 9. The armature 46 of said lever oscillate arms 52.

spring such as 52 ing point, and hasa transverse slot 57 for exposing the character to be printed, In order to prevent smearing of the printed characters on th paper as the typewheel and guard is moved transversely thereof, the slot 57 of said guard is cutaway at each end at 5'8 and 59 as shown in Fig. 14, where by no part of the guard comes in contact oscillatingshaft 51 (see Figs. 2, 5 and 6), said shaft 51 having a foot extend ing outwardly therefrom and adapted to be engaged and oscillated by a cam whcel' l9 rotatably mounted in the frame. The cam wheel 49 is provided with teeth adapted to be engaged by a pawl l8 carried on the nioving feed rack 42, (see F By this construction it is seen that every time the feed rack is returned by spring 56, the can; Wheel 49 is given a partial rotation and acts to depress foot 50 and consequently and platen against the paper for printing. This operation takes place preferably by the return movement of the leedrack 42, whereby thetype-wheel is completely at rest ready for printing, havlug been moved to its new position by the forward movement of the feed rack l2. A may be provided to keep tlIQ'fOOt 50 in engagement with the cam wheel 49, and'an adjustable stop 54: fixed at 55 may also be provided to limit the throw of foot 50 under the action of said cam Wheel. l

The circuit for energizing the magnet Y and consequently operating the letterspacing mechanism and the printing mecl1anisin.tl1rough. armature 46 is shown diagrannnatically at 97 and 98 in Fig; This letter-spacing and printing circuit is connected to the battery B asshown. and is closed by an armature 99 attracted by relay magnet S in the transmitting circuit 96.-

for printin the alternations cease and a I currentin one direction continues through sa1d relay magnet S thereby energizing the same and closing the, relay circuit 97 and I It \vill'thus be seen that the relay=circuit 9.7 and 98 operating the magnet Y is promptly closed after the type-wheel has been fixed in position.

Extending forwardly from a shaft 93 mounted in the side plates and 3 of the machine are urine 9% earrving at their outer ends the transversely-extending blade 95. llearwm'dly extending from said shrilt 1: 3 is an'arm 9O inwing a slot 91 engaging ll. pin 92 onthe oper ating lever 83. The blade 95 is located he neath theprojeeting pin 4.0 of the pawl 38, whereby when the blade 95 is raised the pawl is uithdmwn from engagoment with raoh +2. The pawl 37 has a lateral. projootion 37 as shown in l iggs. l and 5, extending over the top of pawl whereby when pawl is raised it rzirries with it pawl. 37 and thus releases hoth pawls from the ranks 'll. andlii to allow the return of the ty'peovheel carrier 27 under the force of its returil arm 69. This time evident that by eiurh OSClllflwtion ofthe arm 83 the paper 11-; fed forward for a new line and simultaneous!y the typewheel Cll'l'lilgti is released from the rarhsi 4 1. and 4-2 and restored to its initiiil'position relntive to said paper sheet. lrloreover, when the shaft is rocked to release the pools of the tyliifiwllt t l carriage from the racks 41 and 4-52 the toothed oheehin bar 79 is also raised to withdrz or its teeth completely from i the path of movement of said extension 38% closed when desired throngh-the proper op{- H5 eration of the transmitting circuit by the f0llowing mechanism:Referring to Figs. 1 and 3. an arm 10f fixed to the armature {l6 one tends laterally through the side plate 3 of the machine and engages with a lever 105 pivoted at 105" on the plnte 3. The lever 105 supports at its outer end a, vertically extending support 106, which is made of two parts telescopically, conneeted so as to yield in its lengthwise direction. Support 106 is a guided in its vertical movement by slot 105 and pin 106" and carries pivoted to its 1lp' per end and insulated therefrom a contact 101 connected to one branch of the oircuit 109. The contact 107 may have a small spring for yieldingly keeping it in extended pcsitionuponthe end of support 106. ,The

type-wheelshaft 4 extends through they side plate 3'and carries at its outer end disk/l insnlated'"therfrorn.- The disk 4 carries on its periphery saf. projecting contact pin 108 i'vl'iich is iii-electrical connection with the other branch 109 of said energizingcircuit. It understood thatthe lever 105 andcontact 107 is vibrated vertically at each energization of magnet Y when a character is printed, and ordinarily the contact 108. is'

not in line with contact 107 v'lor meeting the same in its IIPNViLIdJnOVBnIBHt and closing circuit 109, 110w Contact pin 108 is located onjdisk 4: at a point in its periphery corremechanism.

- vided with a spiral groove 1'2 and pivotally mounted upon the frame adjacent said The present apparatus may be supplied with thesynchronizing device of the well known character shown in Fig. 1, in which one end of the type-wheel shaft d is progroove isa lateral swinging lever 13 having a pin l3 normally in engagement with the piral groove "12. During the rotation of the shaft t the lever 13 by the engagement of is connected in the transmitting circuit for pin 13 with the spiral groove is adapted I to swing laterally across the machine until a shoulder 13" of'the same comes in contact with the pin let ofqtlie type-wheel shaft 4,

whereupon said typeqvh'eel shaft is held" from further rotation. The'lateral travel of swinging lever 13 along groove 12 is sufficient to allow the type-wheel shaft 4 to rotate at least two full revolutions before shoulder 13?" comes in contact with the pin 14% for stopping said shafts. This allows the type-whcelj; to present any one of its characters to the printing point without danger ,h'ig'tlie' shaft d being automatically stoppedl. During the operation of the machine thissynchronizing lever 13 is disengagged froign groove 12 each actuation of magnet Y and is provided with spring (not shown) a for returning it to the left side i of the machine. The swinging lever 13 is W i n: a

' nigmary-elleferring to "diagrannnatic Fig. 15, the several operations of my ing apparatus may he briefly summarize'd as followsz It isunderst0o'd that a transmitter of any usual type (not shown) sending alternate impulses. of current through the circuit 96, the number of said impulses depending upon the character on c nnected to the armature 105 off magnet Y.

the type-wheel which it is desired to print,

whereby the'polarized escapement mocha;

nism positions the type-wheel'in its printing position. The last of the alternate im- J pulses which fixes the tYPGrWhGBl. in its position continues through the circuit 96 in direct linefor a suflicient length of time to energize the relay magnet S, closing the relay circuit 97 and 98, energizing magnet Y Iptor operating the letter-spacing and printmg mechanism as above described. When the operator at the transmitter reaches the end of a line he presses a key for positioning the type-wheel to bring

contacts

108 and 107 in line,

thecircuit

109 and 110 being then closed by causing the printing magnet Y to attract its armatureelti The actuator Z or" the winding mechanism is energized by its

circuit

103 and, 104" independently of r the other circuits by the contact closer on the type-Wheel'shaft.

I It will thus. be plain that there is provid ed in the present apparatus a separate and individual actuator for the letter-spacing mechanism, line-spacing mechanism and the type-wheel shaft tension mechanism, and that each one of these actuators is energized by an individual relay circuit under the control 1 of the transmitting circuit 95,

whereby each relay circuit be quickly responsive to the operation of said transmittingcircuit for positively operating its respective actuator andcorresponding mechanism.
