Application iilecl November 17, 1890. Serial No. 371,662. (No model.) Patented in Switzerland April 20, 1800, No. 2,078, and in Germany May 6,1890, No. 57,812.

To @ZZ whom/,it may-concern,.-

Be it known that 1, OznsLAW RYMTOWTT- PRINcn,1nanutacturer, of Geneva, in Switzeriland, have invented certain 'new and useful Improvements in rIype-Writers, (for which Letters Patent have been gran ted me in Switzerland, dated April 20, 1890, No. 2,078, and in Germany, dated May G, 1890, No. 57,812,) of which thc following' is a specification.

Themain object-f. the invention is toallow officials and other `governmental officers to exchange cipher-writings which are absolutely undecipherable to all except those who possess the key of the writing and a machine similar to that Withwhich Vthe cryptogram has been Written. These cipher-writof iso-small diinen'sioi'isthat'theyl may very easily be dissmnclel.hyfhsf- .-vlio are commissioned withthelr transmission. The said cipher-writer prints the letters upon a very thin and narrow paper ribbon, which may be pasted upon a sheet of paper by the receiver of the writing, it' desired. The machine is so small in size (about three and a halt inches in diameter and an inch and a half in height) that it may easily be put, with a suitable inclosi n g case, into-.ones pocket, and, nevertheings have, moreover, the advantageo't'dbeing y,

'lesaall yits,parte....are...constructed with such lsolidity andl precision that its good Working is insured, evenif used by unskilled people.. The machine may be further provided with' mechanism for, rolling up` the paper ribbon' into avery small compass for -transmission.

A is the base ot' the machipc.

C O are two pillars fixed ,to'the base A,and to which is hinged the ring D, which sets down upon a third pillar E, having a spring catch- F, by means of which said ring isheld upon the pillar E. Said' catch may be moved to allow said ring to loe` lifted like a cover when it is desired to look at one ot' the inner parts of the'machine,

The lettered ring D supports a lower xed thereto and beneath hunk-the' lower portion of WhichisadjuSted l bridge-piece Gaand a plate h', screwed.. to the under face of the hub h, prevents .theraising andremoval of the disk l-I out, of vthe bridge-piece G.- The bridge-piece G isprovided with suitable openingsto allow for the movement of the mechanism described below. The disk H, bearing the types which are J, screwed beneath and to said disk H, sfnl,` ther; provided with an internal range of teethsuitable recess of the bridge-piece G, and havinclusive, arey shown-on an enlarged s'c'alcf" bridge-piece G, screwed 'or soldered the same, and which- I bridge-piece G Qltriesa Vmovable"1i1g or disk Y. ALI bearing'the type-ring. The disk H has a '9 engraved 1n a type-ung arm K, sliding' in a Y ing a small. roller-at itsextre'mity to'engage 'the intervals between the teeth of the range l each time the said arm is pressed'outwardljlr by the enlarged portion m of the hand stem or key M, Figs. 2 and 5, againstwhi-ch it is constantly pressed by a spring L.- The purpose of this disposition is to render the disk H. temporarily immovable while letter is printed or iinpressed'on 'the paper ribbon.

' oted the rollers which guidethepaper ribbon upon whichthe'ilh'pression is inadein print' The -hub h of the disk H being movable in the bridge-piece G, the disk H may be turned n any ldirectionV when said arin K is at rest. he revolving of, the disk H is caused by means cfa square-part of the hand-stem M, which engages into the ring N, screwed to the Iupper end of the hub h of the disk ILand into which it may be depressed axially from the position shown in Fig. 1.tofthat`shown in Fig. 2. It one turns: the hand-stein M, the disk H and typering J are also revolved. The said stern M maybe withdrawn when the machine is not in use and when the machine is to be put in ones pocket. As showt-1. in Fig. 9, said stein containsa screw-driven fn, intended to be used after removal from the stem M to unscrew and disconnect the parts when the machine is to be unmounted. Around the hub '7L there is placed a toothed wheel b and a hand or pointer 0,' which are connected and are free tdt-urn together, r*nd said pointer is intended to de'ternneeas' it' will be shown below,'the letter or figure upon the ring-shaped iudieatortor dial D, Fig. 5, which will be printed, according to the position of the disk Il when the stem M is depressed.

The hand or pointer O is combined with a 'mechanism which will be described farther on and which is especially intended to produce the cipher-writing.

The base-plate A is provided with three Vertical walls QJ., Q2, and QS, to which are piving, and the levers R, S, and T are pivoted to these walls. the cross-headed end of the hammer-lever U, and the movement of the lever R causes the advancing of said paper ribbon after each printing, as hereinafterpnore fully described. The platen-lever S is at one end depressed by the liaxnmer-leverU when the stein Mis forced down and at its other end is raisedwith. the paper ribbon' V against @slower-surface of the types u'pen'thering .lottielaise Il," llhe lever T is intended to produce the advancing of the inking-ribbon, which passes between the paper ribbon and the types, aahereinafter described. These three levers are acted upon by suitable Vsprings. '172, s, and t. The hammerlever Uispivoted at u to the base-,plate A and is acted upon by the lower end of the stem M each time the latter is pressed into thema-v chine. By such depression thealinost simultaneous movement of the levers R, S, and T by the lever U is accomplished. The paper ribbon V is lifted against the types by means of the platen-levers and the impression `vis given. The pawl rI' at the end of the lever R isv raised, so as to engage and turn the toothed wheel w one tooth, when the stem M is released and the lever It, is raised by its spring r2. The toothed Wheel w' turns the roller W, which is preferablycovered with i lidia-rubber,

These levers are acted upon by A einem drum Y or a holding-case which contains' a quantity of paper ribbon for writing the paper ribbon V passes beneath a rollerZ and' over the head-,piece offthe'l'ever S and over the roller YV and then betweenthe latter and the roller X, which it 'surrounds nearly entirely, and from which it leaves the machine, as shown in Fig. 2. Said paper ribbon case or drum Y is fixed to a sliding arm y, which moves in a su itable slot in the base-plate A.

When the machine is not used, one may turn over or lay down the drum or case Y by hand and retract or move the same in between the base-plate A and the top of the machine, as-sliown in Figs. 1, 3,14, and l5. When one wishes t'o write with the Vinachinejlihe sliding arm y is pulled outward and the drum Y raised upward, as shown in Fig. 2f A suitable` spring-pawl ys, engaging notches in the sliding arm y, maintains the latter in either of these two positions. The drum or caseY,

holding the paper ribbon, is connected to al down or stood'upright, and the parts move together either while being pushed or re tracted within the machine or v'when-pulled out for use. I prefer to have thespring-pawl y2 engage a'notch of thesliding arm 'y to heid the parts when distended or drawn out, because when retracted they are held by fric 'tiener'.asnitable inclusive rase...

Fig. 2 shows a vertical section of the peculiar form of the base of the walls Q2 Q8, supporting the rollers W, X, and Z, whichforin a channel for the paper ribbon to follow 'the path described above and shown in Fig.` 2 under the roller Z, and then over between and' around the rollers W' and X.

-a spring 5, nsecured to the bracket-arm' 30, and

is raised at the end opposite to .the lever 'l and depressed with the said lever, whereby the pawl am acts upon the ratchet al? of the drum A2 through the spring ai, causing the pawl to take up a tooth of the ratchet-arm and the drum to be rotated by the upward movement' of the lever T, operating the le# ver A".

"The machineis, moreover, provided with a cryptographic'al disposition, by means of whichthe hand or pointer O may be displaced from time to time with regardto the types of vthe disk Il, either on the left or on theright, when the machine is printing. The medirse...-

` vided with a notched collar at its upper end,

ism which effects this function is. more -par' ticularly shown in Figsnl, 2, 6,7, 8,"and S.

The hub h of the disk H is notched or proand the cylindrical box H has aoentral opening that ts upon s'aid hub, and the ring N tits upon the top of the hub h over the box Hf, and screws 40 pass down through the ring N into the hub to hold the box in place. A second cylihdrical box H2 is connected with the box H by the small screws h2,

Fig. 6 shows by an-inverted plan, and Fie. 7 by a plan view, the mechanism of the boxes -H and H2, and Figs. 18, 19, and 2O 'show the same mechanism more perfectly.

As will be understood from 'the above description, if one places them-find.; @pgp-i :er upon a letter or igure of the ring D and depresses' the stem M as far as it will go into the'maohine the bolt or slider K is pressed 'iu'to'theteeth I of -the disk H, which is there-- by Aarrested, and the'lever U. is operated and, as depressed, operates the lever S to throw the paper ribbon V against the type of the ring H, the inking-rbbon beiuginterpos'ed between the type and the paper, Aas 'in other type-writers. The above-mentioned-Y-hand or pointer .which is free to turuabout the hub,

of the disk H, is fixed to a gear-wheel b,aud I provide a shallow pinion a and a deep pinion' a', which arepivoted t'o aswiug-bridge or Arocker k, Figs/6, 18, and 19, and either one or the other of saidpinions is brought into gear with the wheel b. The rocker lo is pivoted to the plate of the box B2, and it is con nected to an arm or lever k; having a pin-la2 at its *outer end, and which pin k2 projects through aslotin the plate of the box I :l,and said pin.

is grasped and moved to swi'lug'the rocker 7c soas to bringeither the pinion a or pinion a -into mesh-with the gelrgliltee-ai-?. c letters R and L are cngravedat the end of the slot to indicate if the lever K is placed for right orleft hand motion of the wheel b.' The deep pinion a is constantly engaged with the pinion a and wheel c.4 In one position of the lever-arm 7c' the wheels and pinions c, a', a, and b are in gear, and movement is communicated in the order named, and in the other position of the lever 7c the wheels, and pinions c, a',

Aand b are in gear and the pinion d runs free.

Thewheel c, which is pivoted between theboxes Il and H2, is double, Fig. 8, having above the teeth which are. in gearwith the pinion a a narrower range of ratchet-teeth', acted upon by a pawl g, fixed to a lever O', which lever is pivoted-'at o', Fig. 7, to the box or case H2, and is ,acted upon by a spring o2.

On thelotherhandhe wheel .cis-combined with a toothed wheel d, provided with a notched cylindrical rimior skirt d', the latter surrounding ,and-interruptedly covering or straddling the ratchet-teeth of' c that are the pawl and the ratchet-wheel prevents the pawl g engagingwith the ratchet-teeth of c.

. The notches or openings are'niade so as .to

open up or uncover sometimes one and son1etimes two or more of the ratchet-teeth of the wheel c. The ratchet-Wheel d is acted upon by a second pawl g', which is also pivoted to the lever O', and the lever O carries an arm e., having at its end aroller e', which is pressed toward the cen-ter of the machine by the aforesaidspring o.l The toothed wheel d and its rim or skirt d are connected to or formed with the arbor on which they turn, and the wheel 'c and its ratchet are loose upon the same arbor. Above the box-top H', upon thearbor of lthe wheel d, is a pointer d2, and beneath its sweep a numbered dial is engraved upon the box-top.

The stem M is provided with a projection m2,which acts like a wedge and passes through asuitable groeven (see Fig. 1l) of the ring N. Said projection 'm2 repulses or presses back the roller e and arm e each time the stem M is depressed, as shown in Fig. 2, and thereby causes a backward oscillation of the lever O and a consequentmovement of the parts connected therewith. When the stein is lifted again, the lever O' is moved back into its normal position by the action of the spring o2. Each oscillation of the lever 0 causes the ratchet-wheel CZ to be turned one tooth, and the notched rim or mantle ci', making part of' d, is consequently correspondingly moved ,every oscillation of the lever O'-that is to say, 4with every depression of the stem M, which is simultaneous with each. printing of I OQ a letter or iigure.- lThe pawl g is also moved 'each oscillation of the lever 0', and it sometimes acts'upon a tooth of the ratchet c through the notches or openings in the rim or skirt 61'; but it sometimes bears against or rides over upon a face-part of the rim or skirt d". In the first case it causes the wheel -c to be turned one tooth and'acts upon the pinion a or a', and causesthewheel b, and also the pointer 0, to be turned one tooth to the left or to the right, according tc the position L- or R of the pin K2 andthe pinion a or a that is in gear with the wheel b. ,In the sec- Irv ond case the ratchet d turns alone and the y pointerO is not displaced with regard to the disk H. The displacingof the pointer 0 with regard to the disk H is therefore determined by the ont-cuts or openings. of the 4rim or skirt d', which might becalled the. irregulator, and which may be Varied at will, provided those machines which are to correspond with one another (the machine oi. the senderand that of the receiver of cipher-Writings) disk H, except when operated, as described, .by the pawl g, wheel c, and pinion d or a.

. haveone and the same irregulators. A spring rse The key of a cryptographical communica tion written with one of these machines conj sists in the knowledge of the position into which the pointer O, thorpin Kaud. '.he irregulator dis to be placed'at the printing of the first letter or figure in'recopying the cryptogram into clear writing. To facilitate this,

lthe boxes or cases I-I and Hareiprovided around their periphery with a double scale (see Figs. 4 and`10)having as many divisions as there are types in the machine. Those divisions are marked R and L and are numbered from .left to right in one circle (the Rcircle)'and from right to left in the other or L circle. The number of divisions in these peripheral scales agree with the number of div'isions int'likeuengraved dial-beneath the pointer d2, and lthe key of the machine is a were written.

number of each scale or dial and the R or L (right orleft) position at which the ciphers The operation'ho the machine in writing the cryptogram is substantially as follows:

YAn official, for instance, desiring totsend va cryptogram sets the pin 702 toL,the 'hand or instrument-thusset the pointerO to 10 upon theperipheral scale L, 'and sets the pointer d2 to 10 upon the circular dial,wh en the key will 10. th the ciaitvrite`s=^o`ut a cryptogram, the first' word of which,for illustration, is Paris, and in so doing brings the pointer successively to the letters-of this word on the disk Il andvde'presses the hand xstem'M, operating the mechanism, to give the impression upon the paper ribbon.--v The word Paris is not-impressed on the ribbon, but

Vthe cryptogram C L I-I D 3 is impressed,

which is eminently unintelligible. This is sent with the key toits 'destination,and the receiver, who has a similar machine ,to the sender, sets hisinstrument upon thekey l0 andthe receiver, knowing the key and setting his similar machine atrial-5R15nadie-ig the characters sent, will pri-nt oit` ifl\lew`York. Thus a message of any length can bo written to form the cryptogram. During the writing out of a message by the successive depressions of the hand-stem and the operations effected thereby, -the pointer d2 is moved a point for each depression of the hand-stem M by the movement of the lever O', pawl g', and wheel d. This movement also operates the pawl g, and' the skirt orv rim d' moves with the wheel d beneath the edge of the pawl g,

atintervals covering up the upper and smaller row of teeth of the wheel c and at intervals uncovering them for the'pawl .g to fall upon, engage, and operate said tooth with cach movement of the lever 0 and in un'ison with the wheel d until the skirt d again comes beneath the pawl g and lifts the same, away from said teeth. The'pawl g will then move idly over the face of the skirt until the next opening therein comes beneath the pawl.

The movement by the paw-l g of the teeth of the wheel c operates and shifts thepoint'er 0,

one letter for each tooth, in one direction,

through the intervention of the Wheels aand b and in the other direction by the wheels a' and b', `and the wheels a and a', being of equal size, will cause a like degree of movement in the pointer O. It will thus be seen that while writing out a cryptogram the pointer O will thus be irregularly and progressively shitt- -in readable characters the same irregular andprogressi've shifting of the pointer O takes place in a corresponding manner, but

eti-as the-writing otl the message proceeds,

in the opposite direction, so that. the properletters arefprinted by following out the char- I acter of the cryptofegram.`

The above-described machine may pleted, as shown inwlifigsf.'10.. and""13,"by meansrof theaddition of a second series or range of types J', placed concentrically to the first one an'd intended to render the cipher.- writing of the machine still more undecipherl able. The lever S being'placed as indicated in Eig. 10, if one depresses the stem. IVI, as above specified, the lever will press the paper ribbon against the two types, one of the series J and one of the'series J. The text thus produced will contain for each letter of-the cipher-writing a second letter or iigure, the

purpose ot 4which is merely to render the cryptogram still more undecipherable. Ac-

jcording to the'convention between the sender and receiver of, the cryptogram, the deciphering will 'take place byllirst canceling either each first or each second letter or figure ofthe cryptogram, Iaccording as those letters forming the very text have been printed with the types J or with the types 'J'. i The word Paris will be written either, for in- IIO stance, P IA A K R U I T S W, and willlbo deciphercd in canceling the second and each alternate letter P i A l-R El I T S W; or it may be written I PK A U R T41 vV S,and 'will be deciphered by canceling the first and eachA alternate letter il P il. A U R l l vll S. If one combines now this latter system of cryptography with the above-described one, which is quite the same for the machines with double range of types as for those with only one range of types, one obtains a cryptograph which offers the utmost degree ot' undecipherability; The indicator or ring dial -D must of course be double when the niachine comprises a double range of types; but in view et having only one range of letters or figures shown at a `time upon saidring-dial those letters and figures a re engraved or 6 A to be easily turned by the linger. ,0

paiiitedupon a ring-slider l, placed under- "reatli a ring' P, provided with suitable'openings in which appear theltteifs and figures ofthe ring-slider PT" According to the position into which the latter is placed by means of the pin or bolt p, the openings of P will' show either the letters or iigiires corresponding to the types Jer the'letters or iigiires corresponding to the types J. The ring J js provided witlia circulaiprojection bearing npon a. corresponding recess of Jthe disk Il', and the riiigJ is provided with a circular projection bearing upon a corresponding recess ofthev ring J. It appears, therefore, that the ring ,J is free to be turned with regard to the disk Il and that J is free to be turned with regard to the ring J. As shown in Figs. l0 and 11, those rings J and J are provided with holes or, recesses ji and js, corresponding tothe types, and to the disk I-I there are affixed two 'springs-j and j', provided with suitable projections, which engage into the holes or recesses lgijs. The ringsoi T ai.; J may be displaced at will with regard to each other and with regard tothe disk H; but thesprings y and 3 allow of lmaintaining the same into a determinated position with regard to said disk.` In View of having at will either only the ty es ofthe ring J or only those of the ring J' printed the support or bearing of the paperrollers and of the levers R, S, and T may be displacedby hand upon the base A, so as to assume either of 'the three positions shown in Figs l2, 10, and 13. vIn the first one,

theinnmner S presses the paper ribbon only against the types of the ring J, in the second one the haininer S presses the paper ribbon against the types of both rings J and J ata time, and in'the third the hammer S presses the paper ribbon only against the types of theA ring J When both types are printed together, the paper ribbon iniist be advanced twice as inncli as when only one .type is printed. With that end in View the leverR is provided with a projection r', upon which the hammer-lever 'l ,L 'bes in the ."1' iddle p0- sition of the paper-bearer, Fig; lo, and this causes the pawl fr to turn the ratcliet-wheelw two teeth at a time, while it is only turned one tooth when the hammer Ustrikes in front ot or' behind the projection o".

The machine, as shown in Figs. 10, 14, and 15, is provided with a small reeling device located in the base A and intended to easily wind up in the form of a very small' roll the' printed cipher message. A kniirled 'wheel .fr is located in the base A and projects slightly beyond the circumference of the latter, so as Said wheel w carries e scar-wheel .that acisnporiapiaf,I

ion e', tl'e'sl'otted stem z2 of which pinion projects out of the upper face of the base A. It o ne end of the paper ribbon 4upon ,which the cipher is printed is placed into the slot of the stem .e2 and it' the knurled wheel u: is then rotated, the paper ribbon will be rapidly wdnnd up on the said stem z2 into a very small commanner to its destination.
