tures 30', etc. and serve as a means for adiusting the tension of the springs 3l. etc. Seven electro-magnets, (30', (302. (30, (u, no,

00, and 007, are mounted on the permanent magnets etc., respectively, and are associated each with one of the pi'iiitiiig pen armatures 30', ete., respectively. i' 'lhe windings of the magnets controllingr the pens 20 and 202, are shown placed in series with each other and connected to the line conductor -tl and ground, while the windings of the magnets controlling pens 20 and 204 are placed in series with eachother and connected to the other line conductor 40 and ground. The windings of the magnets controlling auxiliary pens 20, 20, and 207, are bridged on the windings controlling primary pens 20', 203, and 202, respectively as shown in Fi". 1. The polarizing magnets 50, 50"', and 507. polarizing auxiliary pens 20, 20, and Q07, and theirrespectiveelectro-magnets, may be stronger in their magnetism than the polarizing magnets polarizing pri- I'nary pens 20', 202, 2t". and 20, or the helices of the elmrtroinagnets may have variant numbers of turns to effect an equi 'alent ultimate operation. 'lhe windings of each pair of the magnets and 002, 603 and 00. are arranged so that a-eurrent impulse of one polarity and intensity over one line conductor and the ground will release one pen of that pair of pens in the particular line by neutralizing in the'core ot' its electromagnet that magnetism induced by its permanent magnet and allow it to be propelled by its spring to make an imprint of its particular type face upon the recta-ding tape 5G. while. the other pen of the pair` will he held to its controlling magnet whose normal magnetism will be strengthened by the liic current.

llowever simultaneously with the current through the magnets ot the primary pen a current has .passed also through the magnets of one or two ol' the auxiliary pens, and il the, current intensity ofthe impulses sent over one of the line conductors and ground should be of a value sullicicnt to overcome the attraction of polarizing magnets 50"', 50 or 50T, not only will one, olI the pens ol' a particulai' pair as 20' and Z0: be released to imprint its type face, but also the pen controlled by the bridged electi'o-magnet as 20"" or 207 and polarized by the intensity ol' mag netism ot' the magnet 50 or 507` will he iinprinted siniultaneouslv with the pen ol' the pair 20 and 202. 'lhus it will be seen that by sending a positive impulse of a current 'intensity `within predetermined limits over line 40 through magnets controlling pens 204, 20, and 20, that pen 20" may beim- ,taneously.

printed alone, that by sending aY negative impulse ofthe saine intensitvover the saine line. pen 20" may be imprinted alone and that by sending a negative iniplilse ot' relatively greater current intensity over the same line pens 20 and 20 may be imprinted simul- In like manner, b v sending iinplLlses of predetermined polarity and intensity over 'line l1, peus 2U or 202 may be' selectively imprinted and pens 20 and 20 or 202 and 207 may be simultaneously iniprinted, asiindicated above, while in each case the pen or pens in a particlilar line not imprinted by impulses over the line, will be iuore strongly attracted by their controlling magnets, while the actuated pen or pens are being imprinted. In the circuit diagram Fig. 1, it may ap| l,ar that the` equilibrium of current values may he disturbed by the ,fact l that the coil 20* has no companion or auxilia ry coil. i conductors and b v reason of length they will in practice have high resistances,,hundreds of ohms, whereas the magnets 2 0 to 207 are coiuparatively very low, preferably less thany ten ohms. so that the currents over 40 are substantially the same as over -tl for the same applied potential. Magnets 203 and 20 then get the sanieenrrent values and curi'eiit conditions t s magnets 20 and 2 0?. The magnet 20 is not subject to quantitativadiscriniination. The circuit connections of the three magnets, 20, 204, and 20` fluter se is immaterial whether series, multiple, ete., so long as all participate in currents received over the line conductor 40. the turns of each and the permanent field 'strength of each heini,r so adjusted that a greater current iiitensity is required to operate the peil inag-V iiet 20 than is required to operate the pen of magnet 20. 'l`he saine is true of pens 20', 20"', 20"' and 20T and the line conductor 4l, the inal and critical adjustments being that pens 20 and :Z07 rquire greater operating ,A i

currents than pens 20' and 202.

An anvil 57 is placed opposite the printf ing tace ot' the pens. 'lhe recording tape 56` bez; upon lthe surface ot the anvil and is.

drawn laterally l'roin the roll of tape 58, before the printing faces ofthe pens by means ot' rollers 5U. 'l`lie receiver illustrated isar,

ranged for electro-chemical printing and af,

battery 54 is connected to the pens and the anvil for that piu-pose.

'l'he transmitting device. togetherv with iis associated circuits, shown in Fig. 5 and comprises a drum 7l of metalor insulating mai'fi'ial, carryin,\ centrally ou .its cireuiiiicrence a row of pins 7l -and driven by belt l'rom any source ol power. drinn 70 bears upon drum 71 and is driven thereby. A cen,1

'l`he conductors 40 andJfl are line izo tral row of apertures 'i0'.in drinn T0 permit ot' the iuvaginatioi'i ot' the pinsil. An iinpulse alternator li' comprising aserles of. iiisziiated contacts l5', 1752, 15, 1.51, and 4 is connected through a relatively 55 grounded generators n mounted rigidly 'ipon the frame ci the transmitter and-provided with a. contact maker 16 rotated simultaneously -with the dr in T1 and at a fixed relative rate ot rotation by means ot spur gears "TQ and i6@ thus always maintaining a definite relation between the position ot the contact maker 1G with respect to the contacts l', 152, 1,53, 154, and and the drum Tl ior anj,7 instantaneous position ot the drum Tl. lrushes #3, 7 & 8 are rigidli7 mounted upon the trame ot the transmitter' and are insulated therefrom and from each other. As will be explained subsequently a definite distance is at all tiines maintained between the brushes and the rollers 7G 3: Tl. A pair of flexible brushes 9, l0 are mounted in a brush holder carried `by the frame o'l the tran'smitter'and are adapted to make contact with and between the brush 6 and brushes? and 8 respectively. rhe contracts and 153 ci' the alternator li are connected to the negative terminal of the generator 2 While contacts l5`2 and 15 are connected to the positive terminal or" similar generator' The generators have their remaining terminals connected together and grounded at l. Contact of impulse alternator l? is connected to brush 6. Brush 9 is high resistance il with line conductor 40, While brush l0 is connected throughs. relatively high resistance l2 Whose value is the same as resistancc il, with line conductor ell. Brush 'Y is connected through a conductor i3 ot' substantially Zero resistance -with conductor 4G, and brush 8 is connected through conductor 14 of equal resistance with conductor 18j 'to line conductor all.

The wiper of alternator 1T is adapted to malte contact between the insulated contacts 15 and i, l5L and i, 153 and etc., thus placing potential impulses ot predetermined polarity upon brush 6. A tape el is adapted to be passed from a roll ct such tape 4:42,

between the brushes f) and l@ andthe brushes f3. T and 8 and betu'cci'i the rollers T0 and 7l. The* friction of the tape and rollers is adapted to cause the longitudinal movement oi the tape between the brushes, and a series of cent al perforations sie in the tape are adapted to register .with and oe engaged by the pins in the drum T1, thus serving at all times to maintain predetermined register between the tape and the surface of thel drum "Tl, during thelcngitudinal movement ot' the tape through `the transmitter. The transmitting tape, through tl1erein, permits contact ot brush f) with brush G or with both brushes 6 and '7; similarly brush l0 may malte Contact with brush G or with bothbrushes G and S; thus either line conductor maj7 be connected through resistance with the impulse alternator 17 vand through the impulse alternator with or 3, or either line circumference included perforations gitudinally of the tapealternator and through thrY impulse alter' nator with grounded gene ators '12 or' 3. rl`liese contacts through the. transmitting tape are selective in tivo functions-First, in selecting the proper contact tween the brushes andI` second, in selecting the prope instant with reference to contacts viousljT or to be made subseqieni-ly. A time relation exists between the speed ot' the transmitting` tape and the speed oi the Wiper lf3 of impulse alternator l?, which permits ot the selection ot the propcrpolarity of the impulse. A time relation also exists bet-Ween the speed ot the transmitting tape,l impulse alternator and recording tape, that the printed components `ot the characters may beproperly spaced and further that the characters may be correctlyspaced from' ach other on thel recording tape.

'lhc'recording tape as well as the transmitting tape is moved longitudinallv in well known manner. l prefer, however, to employv small e'ecric motor driving rollt ei-s, as indicated at 5f) and at 'Y0-Tl in the figures i ich serve to pull the tape at unit'orm and proper speed through the respeztive devices. l

Control of the printing pens 20 to by pert'orations in the tape li isas follows: The periCA rations in the tape i? 2 .i confined to tour longitudinal rows 3 l l', 2 and i, of Fig. Q. The rouy of central pertorations in the tape are, as has been said, spaced to admit the pins on the drum 7l, the spacing ot'the pins being in such relation with the speed of the drum 7l and Wiper 16 of alternator ll' as to alloriof Wiper 16 making contact successivelyv hetween any two contacts as l5" and i and passing to the' middle portion of a third contact 'While the drum Ti is rotated a distance equal `to that defined by that portion of it between any two pins 7-. Further the number of the pins on the drum is such and their relation to the viper is so coordinated that when any pin is in a Vertical .position the viper is malring contact between-contact'and a contact #inflected-to the positiv terminal ot' thev CVnerator. The brushes 6, Y and 8 are disposed a distance away from the axis of rotation of ther drum 7 l such that `when the tape is placed '1n position to transmit a message the contact line between the brushes when any pin or drum 7l is in .fertical position will fall on one ofthe central periorations in the tape. Thus by properlY spacing lonand transversely the perforations between any two central perforations si, positive and negative in*- pulses, oty Variant intensities may be selectivelj,7 sent over either line through its assomade pretvnsitivs may hv svnt siinultaiivously ov'vr liotli lillvS.

It will be observed that each elemental line when imprinted merely abuts a preis toi-med without allowing any' portion oi3 one. imprint to overlapor register Vith another. Then too every letter or numeral is printed without any useless appendage, thus greatly increasing the clearness of thei'ecorded message. This gain when taken in connection with a transmitting tape of only tour `rows of pertorations results in producing a device ot great commercial utility.

Further it will be noted that as l am enabled in mydevice to simultaneouslyT irprint tivo pens or more with but a single inpulse of one polarity, that the number or'.' impulses for a given message will be small as compared with the number of pen operations required resulting in a slower commutation of currents inthe line for a given speed or" transmission as measured in numbero words per unit of time.

lll/'bile l have illustrated my device in connection with tivo direct current generators as a source of supply, it is obvious that I may utilize any other well lznown source of supply. Further it is obvious that while l have shown a particular design 'of transmitting and receiving devices, many modiications may be made therein without departing from the spirit or narrowing the scope of my invention.
