TO ALL WHOM IT MAY CONCERN:`

-Be it known that I, ROBERT KIRK BOYIQE, of the city, county, and State of New York, have invented a new description thereof, whchlwill enable tlise skil ed in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to a newr telegraphic-printing apparatus, which is so arranged, lthat it will adapt itself te every variation ofthe weather, and that `will utilize the whole power ofthe current' The invention consists, first, in a new arrangement of connecting the horse-shoemagnet with .the electro magnets.4 l v I I In my new apparatus four electromagnets are employed, apair being arranged on each side ofthe horse- The two electro-magnets oneuch side arearranged one above the other. Two horse-shoe magnets areirmly'secured toan oscillating-horizontal bar, in such a'manner that each end of each horse-shoe is between the two opposite electro-magnets.

By means of this arrangement the through current, -which is generally obtaincfhis avoided, and the horseshoe magnet willmore easily change its position', when the polarity of the electro-magnet is reversed;

The invention also 4consists in the application of two springs, of which one is arranged on eachl side ofV the horse-shoe magnets, so as to be forced 'back by the magnet, when the same is attracted to .one side, and to aid in repelling it to the other side, when the current is changed. l l

By means of these springs the motion of the horse-shoe magnet can be regulated, in case the electro-magnets on one'side should be stronger than those'onthe other side. l i f y' Y By setting the spririwhicli' is on the same side with the stronger coil, by means of a 'set-screw, closer-'to the horseshoe, thus strengthening it, and by weakening the spring on. the weaker coil, the horse-shoe will be repelledwith the additional force-of the stronger spring, when attracted by the weaker electro-magnet?- The inventin consists, third, in a new method of connecting the horse-shoe magnet with. the Vlocal magnet,

This connection consists of two wires, which reach from the coil of -the local magnet tojits lcattery, and thence to a slotted standard, in which the horse-shoe oseillates, andto a sleevein which th'e'horseshoe-is held, respectively, the saidsleeve being held between the two arms of the aforesaid standard. i

As soon as,'by the actionupon' the keys, 4the m'otion of the armature -is-arrested, t he sleeve will'be' brought in contact with the standard, andthe circuit between the two wires of the local rmagnet will be established, so that the same will draw down its armature. l l 'l The invention, vfonrthly, consists in connecting the local magriet with a forked lever, acting'as an escapement to .a toothed whe'cl, which has a tendency to revolve, but is detained by the aforesaid lever.

As soonas theI armature ofthe local magnet is drawn down, the wheel will be released, and willrcvolve until it is'stopped by another forked lever connected with the type-wheel, as 4will hereinafter be' more fully described. y

By such a mot-ion ofthe wheel; the same will, by m'eans of pins, act uporra lever, which draws a clutch into the Ateeth of a stationary `tlisk, the number of teeth on the same corresponding with thennmber of letters on the type-wheel. I f l f 'l l j Thetype-whel is mounted on an'airle, which carries an arm that strikes against the'aforesaidclutch, when the same catches into one-ot` the teeth of the aforesaid stationary'clisk, and which thus stops the motion of the axle, to which it is attachedand consequently also the motion of*the'type-wheel.V The type-wheel is thus brought to a stop and-ready for printing. I A

'BLEU The invention alsosconsists impartingto thou-axle, to which the type-wheelis attached, motion from sloot s, turning upon a stationary agile, which is a continuation of the aforesaid type-wheel axle.

V'.lfo the 'slccvc'is ivoted anelhow-cam which strikesafaiust a in en the type-wheel and thereb revolves p 7 o p .l y

f the same as 'the sleeve isrevolvcd.

'Botas soon ase ,he type-wheel isstopped in Vth'c aforesaid rnaniner, the cani will'not be able to movie it any more,l and will, as it is attached' i'ofthe 'revolving sleeve', .beu forced against the `pin on the type-wheel, and will thereby be turned aroundlitspivot-pin, so that its other arm will strike against a pin on another sliding sleeve, which, as ift is thusmoved, acts upon a'lever projecting from 'an oscillatngshaft.

As the latter shaft is turned itwill press a cushion which is attached toit against the type-wheel', and will thereby imp rcssthe required letter upon the paper, which isbetweenti'ic cushion and the type-wheel. i

The invcntion'iilsio consists inconnec'ting with the oscillating axle,v'\vhi`ch carries the printing-cushion, the forked' escapement-lever, which arrests the motion of thetoothed wheel, that has been released by the action of the local magnet, as above described.

' When, by the stopping ofthe-typc-wheel, the .said-'forked lever ismovcd, it acts to again release the toothed wheel, so that it may be locked by the lever which is connected with the local magnet.

A spring acts to draw the printing-cushion and all the parts connected with the. oscillating axle to which it is attochcd'into the original position again.

The paper to be printed is fed between two. drums," which are'movcd by the intermittent rotary motion oi` the toothed wheel that is connected withthelocal magnet.

While the aforesaid toothed' wheel'rwas turned, when released from the fork that is connected with the printing-cushion, it acted upon the lever which cai-ries ythe clutch,-itting into the toothed disk, so las to draw theclutelr eut,`and thereby allow the' typewhcel and its axle to revolve'again.

The invention also consists in the device for connecting'th'eaforesaid apparatus withthe armature of the mainniaghcts.

The oscillating armature operates an oscillating escapement, which acts upon a toothed wheel, mounted on 'aslcevc that is fitted up'on the type-whcelvaxle.

lThe little toothed wheel has half as many teeth asv there are types, and its sleeve isconhected with the sliding clutch which locks into the toothed disk. i

As the toothed wheel is released lby theoscillations of its'levcr, and movedv by theaction of aspring, the clutch-arm will move 4'ith each move of thc toothed wheel, opposite to another tooth of the toothed disk, and

when the oscillations of the escapeme'nt are stopped, the clutchv will beopposite that tooth into which itis to vbe-loeked bythe actionot` the local mognet.

When the'arm on thetypefwheel shaft strikes the olutcln-th-c requiredtypc et' the wheel' will stand oppas site theprintin'g-cushion;

The correctness of the operation is evident, as each motion of the armature makes one corresponding motion Vof they toothedeseapoment-whecl and one motion of the clutch-arm, which nieves `opposite the toothed disk, the

disk having as iuiany recesses as there are types.'

Each recess 4represents one type, and that one into which the clutchearm is locked will be the representative' of that type,"which will be brought opposite to the printing-cushion.'

The inventionl consists also in the device for winding up the spring, which moves the escaperuent-wheel'.

The outer end of this spring is attached to an annular r'atchebivhcel, w'hichis held on tbc side of a stationaryl rin'gpand which is con'ncctcd'with a suitable pavrl.l it On the samesleeve to whichV the escaperuent-whcel and theinner `end of the spring are attached, is also attached an'inclincdicam', upon thel edge of which straddlcs'e. forked lever, pivoted to an erin that projects fromthe type-wheel shaft. i i p A' i; i

As the shaftl revolves, the fork is moved on the oa'm,`and if the spring is unwonnd, it will be wound-,up

again by an arm projecting from the fork, which arm only strikes a block on lthe spring when it moves over thotportion ot' the edge of the com which is nearest to the annular ratchet-wheel. "The type-wheel is inked by means of a brush, which is mounted on i angles to thc type-'wheel shaft.l i `i i i i i i ,i v A suitable-device is `obtained to' arrest the type-wheel ata stop, beforerbeginnirig a` sentence.

Foce-platos, bo, are secured to the ends ot" each electro-magnet, as 'shown in gs. 1 and 7.

'lhe four face-plates on that pair of electrorriognets which' is cn onefside of' the horse-shoes, are opposite the poles of the borse-shoes, and those on the other pair lare also opposite the poles.

Thus it wiil'be' seen' that when 'the appnrntns is sett in operation, the dingonnllybpposite electro-mignotte will respectively ottrnct and repel'thehorsefshocs, and thitifns the polarity of tbe electro-magnets is reversed, the action upoiffthe horseshoes will vberejfersctl', and thnt ths en oscillating motionis "imported to the letter.

It willbeseen thntfb'y this lr'rnngeuit", tbnd combination 'oi` 'tl1emagnets, only one pole of ench horse-shoe shcllbe attracted by only'onepoleof thesnrneelectroningnen-nnd thnt there will vthus be two distinct eiectrof mmfgts to :st-tinct'one horseishoe, and vtwgo'to repel the saine. t Inall other devicesjnowfin'nsg'both poles of the horsesboefor other permanent "magnet, are attracted to the seine side the el'ectro-jin'agnet. l

Thereby a; lnzrgnetic circntis'erentekl-whichpievents thefree action 'of the electric current, as the perina- Uenl? ignei'bripot be relefse'ilwith' the required rapidity. Y i

`By .my uppnr'tus'nosuchcircnit is obtained, :incl the action o f the permanent magnet will consequently bo more certain nntlrre'linble ,then it' is with ony'orclinnry orotherappnretus.

ToLhe supports@ c,-b'y whic'h the electromagnets `nre lielcl, are, attached springs ol d', which are, by'inlenns; of screws, ef. regulated so. esv to press igafinstithe' sicles'of the horseshoemgnetwith greater or less force, es) y i s rd i .Thunfone pairofthe electrovingnets lshould be' stronger thnnt'beipnironthe opposit'c'sidoof the horse-- and to stain when attrcted the stronger electronagnets v ,But even if the electro-magnets@ the twositles oftn'ehorse-shoes.nre'alie, these lsprings will bc ci' greet i service, as those on onev side willv yieldwhen the' horse-sboeis 4:tttrectec bythe electro-magnet towers'them, while they will, when the current is changed 1nd the horse-shoe. nttrectedtoe opposite side, accelerate, the

By means ot' the screws e, the springs can be merle strong or wenk,' ais'm proprlyndjusted the horse-shoe rngnet will move in the 4c entre'ol' the whole force." t

The mngneticcombinntion is thus molde permanent for all kinds of weather nnddegrees of current... To one o f the horseels'hoes isattecherl sil-insulated sleeve,f, which oscillntes with thc horse-shobbtween two arms'proj'ecting from a. pilleng, as is clearly shown in iig. I' f I The pillar, as well as the sleevef, is connected, by means of wires, with a battery, and with n local mogmotion-of the borseshoewith the rebound.- t

aybe desire,.nr1l' when they are net, F, asris indicated iny fig. 1. As long as the borse-shoe oscillntes, the contact between the sleeve and pillnr-arms will be ofltoo short duration 'to establish a. circuit between the 'two wires, but when the motion of the horse-shoe oenses, 'by the action upon the keys C, the sleeve will rest agelinst one arm of the piller, or against on adjustable stop'nrrangef in the same, and n connection `between theltwo wires of the local mnhgne't will thus be estnblishetl'whenevez the osoill'ntions of the horse-shoe magnet cease. I i

- The armature F ot' the local niagnetis'drawn down upon itscoils only when n connection between its two wires iV established, d nringth'e rest of the horse-shoe magnet.

Armature F of `the local magnet is secured to en armf/z, which projects frorn an oscillating horizontal shaft, G, said shaft having a. cran'lr towhich a. strong spring, t', isnttached, which has tbetendency to raisefthe armature F of the'local magnet as sooniis the connection between its wires is interrupted.

' An arm, j, which projects from Vthe a'xle G, acts ns nu escnpenlcnt for a. toothed wheel, H, whichie mounfilecl on an upright axle,'as shown,`and which has n constnnt tendency to revolve in the direction of the arrow ll, figs. 1 und 4, itA being connected with a. revolving belt, c. ns shown. l

the surface of the friction-wheel Hnre set n. number of upright pins, Z Z, asis clenf'rly 'shown in the drawings. i is an oscillating lever, pivoted ncortlie middle to the platform A, ondconnccted at one end with a. sleeve, m, which slides nnd/ tuorns on a. horizontal slinft, J, ns shown in tig.v 1.

From this sleeve m projects radially an arn,11 having e bent-out arm at its outer end. The arm n is in front of an annular disk, L, which has slots cut into its rini, as shown in g. 2, the num'- ber of such slots or recesses being equal to that of the keys C. l

The leverI has an arm, '0, which is connectediwitb e. springdo, that'tenrls' to draw the slee-ve m towards the disk L, so as t-o lock thc'projecting arm of the bar n into a recess' of the disk L.

"'iiily'ulicn the back end of the lever I is held b y one of the pins Z of thewheel H, as in fig. 1, will the` bor u be held ont ot' the disk L, as in lig. 1, butn as soon 4s, by the stopping of the horse-shoe magnets, the` lolnlilnialgnetisfdiawndown', so as to raise the es capemen t the wheel H will be turned by its-belt or cord, sind` will thereby release the lever I, which will be acted upon by the 'spring,p, so that the bar n will be locked into the disk, as shown in g. 4.

The wheel H, when it is thus released by theaction of the vlocal magnet, will not turn' far', as it will soon be stopped by another escapement-lever, M, attached to and swinging on an upright axle, as shown in fig. 4, inwhich also .the manner of stopping' the wheel H by this lever M isarep'resentecl.'

Theqcennectiens ofthe lever M will bel hereinafter described.

I The horse-shoe magnets E E are, by means of suitable-levers, q, er directly, connected with an oscillating escapement-lever, r, which engages a toothed wheel, s, that has half as many teeth as there are keys C.

The wheel s .is mounted o n a sleeve, t, which is tirranged around the shaft J, as is more fully shown in iig. 3.l

The sleeve t carries a disk, u, which is set in an inclined position upon the sleeve, as vshown iniig. 3, and a forked bar, c, pivoted to an arm, w, that projects from the axle J, straddles the edge of'the camu, as shown in fig. 2.

' pin, e', has been attached to the sleeve t.

i The sleeve t receives its motion from a hair-spring, c, of which the inner end is attached to the sleeve, while the outer end-isV attached to an annular ratchet-wheel, y, which is fastened on a stationary disk,'z, that is secured to the platform,-as shown in fig. 2, the wheel y being free to turn around its axis in one direction, and a pawl, a', preventing rotation in the opposite direction, as shown.' Y Atthe junction of the spring z with the ratchet-wheely, projects fromthe face ofthe latter ra blocker pin, lb,`wl1ich can be reachedby the end of an arm, c', which projects from the fork n, as shown in figs. l and 2, when the said fork is on that portion ofthe edge ofthe cani u which is n earestto the ratchet-wheel As the shaft J is, by devices to be hereinafter described, revolved with great velocity,'it is evident that the fork v, which is pivoted to an arm, projecting from the shaft J, willbe carried around the disk et, which is rotated but slowly by the escapement-motion of the Awheel s. Y A

Whenever the end of thespring :c will be unwoimd, or nearly so, the bar c will reach the block b', and will turn the ratchet-wheel y, so as to wind the spring partly lnp again, and thus thespring will/be constantly automatically Wound up as it is being unwound. i -l o l Y The cam u is not so much inclined as to allowgtheba'rc to be locked for toolonga time .withfthe pin t, so

that the spring cannot be overwoundfbut still, to prevent any possible overwiuding ofthe sprin g,a projecting When the :spring Ais quite`v wound ulnthey ratchet-wheel y is then prevented. v Y

pin b strikes against the pin cv', and vthe further turning of the The sleeves m and t are connected by means of a pin,f,whichlis. attached to one of them, and Ets through a hole in the other.

Thesleeve t can only turn onthe shaft J, but the sleeve fm, can also slide on the same. v l

By moans of ,tho rotation which is, by ythe action of the spring a: 'and 'by the motion of theescepemen't-lever r, imparted to the wheel s, and consequently also to sleeve t, andV by means of the constant connection between thc sleeves `t and m, the latter isvalso rotated, and with'itlits bar n.. l

D uring each move ofthe sleeve t, which is occasioned by its temporary release from one ofthe 4pins ofthe escapement r, the end of the bar will be moved from one recess te theother 'of the'di'sk L, and during a complete revolution of the sleeve t, the b ar ln pwill also have made .one complete revolution, and'will stand opposite to the recess inthe disk L from which it started; v. I 7 'f l From the shaft J projects an arm, N, with hook-shaped outerend.'

This arm, when the bar n'. is out of the disk L, fits over the end of thbar n, and allows the latter to f 'revolve freely, being itself n ot detained,'as indicated in iig. 3. But as Boones, by `the action ofthe local mag net, as before described, the end ofthe arm'n is thrown into one of the recesses of the disk L, the said bar n 'willbave been moved into the Vtrack ofthe arm N the endet' which will strike against the-end of the arma.

Thus, by the locking of the ba'r n into the disk-L, the furtherrevolutieu of the sleeves 'm andi is stopped,

but also that of the shaft J, 4cwingto the'arm n and -N vcoming in contact with each other while one of them is and m', and ofthe axle J, is stopped.

firmly locked. 4 v Thus, as the horse-shoe magnet ceases to move, by the action upon Vthe keys, the rotation of. the'sleeves t Between every twosu'ch stoppageathe bar n moves across an equal number of recesses o f the disk L as the horse-shoe has made oscillations; andthe number `ef the latter were equal to the number vof keys between the two'last-touched keys. v v v I I j."

The shaft J carries the type-wheel O, on the'periphery of which therequired types-are arrangnfedl The numberof types is' equal to that of recesses in the disk L, and equal to the nnlniberh'of keys and4 double the number `of teeth o'n the .wheel s. v v

Freni one face of the type-wheel O projectpins, g-, one opposite to ev/ofy type, as shicivhn'indigs.l llA and 4. The shaft J receives its rotary motion by means lof a4cam, lP, which strikes againstpa `pin, IL', that projects.

from the face ofthe type-wheel, as shown. l I L lThecaurP is pivoted to a pin thatprojeets yradially from a shaft, R, which shaft is a continuation of thc shaft J, but notpart of the same, as shown, l I.

I e uspringjr, m', which is attached to an arm projecting from thepin S, has the tendency tosc hold the pin that'the arm T pressesthe sleeve. z" towards the type-wheel, sothat the ping" will press against au arm, n", that projects from the cam Rand will thereby turn the saidA cam'rinto ithe position shown in fig.1, which is such that thezcam will thereby stand against the pin It', so jas torevolve the type-Wheel. At the same time,- the arm willfbe withdrawn from the edge of the type-wheel, as shown in iig. l, and the arm M will rest upon the faoe ofthewheel H, so as to hold a pinyl, between its forked arms without detaining it, as shown, so that the wheel H may revolve if released bythe eseapementj. As scones, by the action of the arms fn. and N, thefurther revolution `of the type-wheel shaft J is stopped, the sanft R will continue to revolve, and the cam l will then be brought withfsueh force against the then stationary pin 7L that the power of ,the spring vit/will be overcome,

handliche-cam will be turned, so that its arm n. will forse the sleeve z" back, by means of the piu j. v

By this motion of the sleeve, the end of the arm T will be moved baolc too,'and thereby-,the arm TJ will he 4.nfifovecl-against the edgeof the type-\.vheel, bringing its Wedge Z between twoof thefpin/s-gf on the same.4

4"By the-same motion of the arm T will the arm M be moved, .to release a pin,':Z,-whieh was brought against one ofitsends-by the rot-ation ofthe wheel H while the same 'was beingrreleased from the' oscapementj.

To the pin Sis also pivoted an arm, V, which carries a cushion in one face, and which, when the pin S is turned bythe stopping of the typeert-heel, is, by means of 'a strong spring,vo, which is firmly secured to a pin projecting from the arm U,pressediagainst the edge of the type-wheel. e

y The paper to be printed fed between corrugated,rollers,pp,, which are set in'motion by the intermittenty rotation ofthe `wheel H, on the axle of wnicha gear-wheehr, is mounted, which meshes into a pinion on one of the rollers 22', as shown. v f I I The-paperrests uponV the wedge Z', and isby the same held at the proper height.

,1 y By ltheaforesaid rotation of the cushion-armi?, the paper is pressed by the said arm against that type on .theevvlieelwhich is'ofpposite tothe cushion, andwthus receives the required imprint.

Torecapitulate the operation of the machine, it should be borne in mind that the oscillations of the horseshoemagnet between every action of the keys C are equal in number to the number of keys that are between the two "last-touched keys.

`Lehigh.titty vr-While the borse-shoe osciliates, the arm n traverses an equal number of recesses on the ldisk L as there aremovesmade by the horse-shoe, and when V'the horse-shoe stops the arm stops also, and is locked into that distant from the same as there have been oscillations-made by the horse-shoe. Y

Then-the arm N- arrests the motion of the type-wheel shaft, and locks the Asame in a positionwhich brings the `required `type in front of the printin,1g-cushion.` ,1" i v v i Therelative positionof the type-wheel is, (as it is stopped by the arm n, the motion of'whichiis regulateth) such, thatthe'same number of types will be 'distant between the type last printedand that, to be printed, as there areikeys between theftwe keys last touched. l Y Y l Whep thefrictionavheel H is by the action of the' local magnetzreleased, itturns and releases thelever the spring@ moved so as to lock the bar n intothe disk .T .1'

The furthbr revolution of the wheel H is stopped by the forked arm M, one of the ends of which receives a pin, Z, asshown' in g. 2.

While, then, the type-wheel is stopped in the manner described, and the paper is being printed, the arm Mjis moved in themanner set foi-th, and releases its pin Z, so that the wheel H may be turned until'it is again arrested by the lever j. v

By this turn-oi` the wheel H, the lever I is again moved so as to release the arm n from the disk 11n/thus allowing the further revolution of the type-wheel shaft, and the paper is at the same time also fed further ahead to take the printed portion of the type-wheel, and thus, by this slight motion of the arm M, the lwhole apparatus is again set for'further operation. l,

As soon as the type-ivheel shaft Tis again free to revolve, the cam P'will assume the original position, and will revolve the shaftas theV sleeve a" will be moved Yby `the arm T towards the type-wheel, so as to bring the cam P against the side of the pin L, as shown in iig. 1.

W representsfa lever, pivoted to the platform A, and provided with a suitable handle, so that its end can be moved into a certain recess of the disk L, to arrest the type-wheel at the stop, when al sentence is to begin.

X represents an hiking-brush.

The same is mounted o n a horizontal shaft, which stands at right angles to thc type-wheel shaft.L

The brush will `be revolved by the typewheel, and, by supplying the brush with a small .quantity ot' ink, the same' will be rapidly spread al1 overr the brush, owing to the rapidity with which it revolves, and will keep one of; therecesses -which is' as far from the recesses Ainto which it was locked before, or rather as many recesses the types uniformly blacked, besides keeping the letters free from gumming up.

Tlie wedge l', on tho arm4 U, serves', besides being a. support for the paper, as a means to prevent the type wheelfrom turning back during the printing pperation.
