TYPE·WRITINQ MACHINE .. 

SPECIFICATION forming part of Letters Patent No.. 470,871, dated March 151 1892. 

Application filed November 17, 1890. Serial No. 371,662, <No modelJ Patented in Switzerland April 291 18901 No. 21078, and in 

Germany llay 61 1890, No. 571812. 

To all whom it may cQncern: . 

Be it known that I, CZESLAW RYMTOWTTPRINOE, manufacturer, of Geneva; in Switzerland, have invented certain. new and useful 

5 Improvements in Type- Writers, (for which 

Letters Patent have been granted me in Switzerland, dated April 29, 1890, No. 2,018, and in 

Germany, dated May G, 1890, No. 57,812,} of 

which the following is a specification. ro The main object of the invention is to allow officials and other governmental officers 

to excl1ange cipher-writings which are absolutely undecipherable to all except t.hose who 

possess the "key" of the writing and a mars chine similar to that with which the crypto~ 

gram has been written. These cipher-writings have, moreover, the advantage of being 

of so small dimensions that they may very 

easily be dis:sembled by those who are com-

:ro missioned with their 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, if desired. The machine is so 

25 small in size (about three and a half inches 

in diameter and an inch and a half in height) 

that it may easily be pnt, with a suitable inclosing case, into one's pocket, and, nevertheless, all its parts are constructed with such 

30 solidity and precision that its good working 

is insured, even if used by unskilled people. 

The machine may be further .provided with 

mechanism for rolling up the paper ribbon 

into a very small compas,s for transmission.

partial plan, of the mechanism for controlling 

the cipher-writing of the machine; and Fig. 21 65 

is an elevation of the paper-ribbon holder at 

the section-line y y, l?ig. 15. Figs. 14 to 21, 

inclusive, are shown on an enlarged scale. 

A is the base of the machine. 

C C are two pillars fixed to the base A, and 70 

to wh.ich is hinged the ring D, which sets 

down upo!l a third pillar E, having a springcatch F, by means of which said ring is held 

upon the pillar E. Said catch may be moved 

to allow said ring to be lifted like a cover 75 

when it is desired to look at one of the inner 

parts of the machine. 

The lettered ring D supports a lower fixed 

case or bridge-piece G, screwed or soldered 

thereto and beneath the .same, and which So 

bridge-piece G carries a movable ring or disk 

H hearing the type-ring. The disk H has a 

hub h, the lower portion of which is adjusted 

into a central hole of the bridge-piece G, and 

a plate h', screwed to the under face of the 85 

hub h, prevents the raising- and removal of 

the disk H out of the bridge-piece G. The 

bridge-piece G is provided with suitable openings to allow for the movement of the mechanism described below. The disk H, bearing 90 

the types which are engraved in a type-ring · J, screwed beneath and to said diskH, is further provided with an internal range of teeth 

I, in which engages an arm K, sliding in~ a 

suitable recess of the bridge· piece G, and hav- 95 

ing a small roller at its extremity to engage 

the intervals between the teeth of the range 

[ each Ume the said ai:m is pressed outwardly 

by the enlarged portion m' of the hand stem 

or key M, F'igs. 2 and 5, against which it is loo 

constantly pressed ·by a SJ;!ring L. The purpose of this disposition is to render the disk

II temporarily immovable while a letter is 

printed. or impressed on· the paper ribbon. 

The hub h of the disk II being movable in 

the bridge-piece G, the disk II maybe turned 

5 in anv direction when said arm K is at rest. 

The revolving of the disk II is caused by 

means of a square part of the hand-stem M, 

which engages into the ring N, screwed to 

the upper end of the hub hof the disk II,:ind 

ro into which it may be depressed axially from 

the position shown in E'ig. 1 to that shown in 

Fig. 2. lf one turns the hand-stem l\f, the 

disk II and type-ring J are also revolved. 

The said stem M may be withdrawn when the 

15 machine is not in use and when the machine 

is to be put in one's pocket. As shown in 

Fig. !:l, said stem contains a screw-drive1· n, 

intended to be used after removal from the 

stem M to unsc1·ew and disconnect the parts 20 when the machine is to be unmounted. 

Around the hub h ti-ere is placed a toothed 

wheel l> and a hand or pointer O, which are 

connected and are free to tnrn together, and 

said pointer is intended to determine, as it 

25 will be shown below, the letter or fignre npon 

the ring-shaped indicator or dial D, Fig. 5, 

which will be printed, acc0t·ding to the position of the disk II when the stem J\I is depressed. 

30 'l'he hand or pointer 0 is combined with a mechanism which will be described farther on and w·hich is especially intended to produce the cipher-writing. 

'fhe base-plate A is provided 'vith three 

35 verticnl wnlls Q', Q2,and Q3

, to which at·e pivoted the i;ollers which guide the paper ribbon 

upon which the impression is made in printing, and the l<:vers R, S, and 1' are pivoted to 

these walls. These levers are acted upon by 

40 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 hereinafter more fully described. 

The platen-lever S is at one cud depressed hy 

45 the ham mer-lever TT when the stem}\[ is forced 

down and at its other end is raised with the 

paper ribbon V against the lower Rurface of 

the types upon the ring J of the disk II. The 

lever 1' is intended to produce the advancing 

50 of the inking-ribbon, which passes between 

the papei: ribbon and the types, as hereinafter 

described. These threeleversareacted upon 

by suitable springs 7·2, s, and f. Tho ham 111orlever U is pivoterl at tt to tho ha;-;c-plate A 

55 and is acted upon hy the lower end of the stem 

:M each time the latter is pressed into th<.' machine. liy such depression the almost simultaneous movement of the leverR R, S, and T 

by the lever U is accomplished. The paper 

60 ribbon V is lifted against the types by means 

of the platen-lever S and the impression is 

given. The pawl r at the end of the lever R 

is raised, so as to engage and turn the tooth eel 

wheel w one tooth, when tlie ·stem J\I is re65 leased and the lever R is raised by its spring 

r 2• The toothed wheel u• turns the roller \V, 

which }s preferahlycovered with in1lia-rnhlwr. 

and which presses the,paper ag:iinst the roller 

X, so that the paper ribbon V advances a 

given distance after each printing. From the 70 

drum Y or a holding-case which contains a 

quantity of paper ribbon for writing the paper ribbon V passes beneat,h a roller Z and 

ove1· the head-piece of the leiver S r.nd over the 

roller \V and then between the latter aml the i :i 

roller X, which it surrounds nearly entit·ely, 

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 suitable slot in the base-plate A. So 

vVhen the machine is not used, one may turn 

ove1· or lay down the d rn m or case Y by hand 

and retract 01· move the same in between 

the base-plate A and the top of the macl1ine, 

aR shown in li'igs. 1, ;J, 14, and 15 .. When one 85 

wishes to write with the machine, the sliding arm y is pulled outward and the drum )' 

raised upward, as shown in Fig. 2. A suitable spring-pawl y\ engaging notches in the 

sliding arm y, maintains the latter in either 90 

of these two positions. The drum or case Y, 

holding tlie paper ribbon, is connected to a 

support y 2

, and the sliding arm y has connected to it a post y', and this support is pivoted to said post, so that the drum can he laid 95 

clown or stood upright, and the parts move 

together either while being pushed or retractecl within the machine or whei1 pulled 

out for use. I prefer to have the spring-pawl

The clrnm A2 is connected with a ratch0twhecl a 12,acted upon bytheahove-mentioncd r15 

lever T. The le,-er T is so placc!l that it 

comes beneath the inner end of click-lever Ax. 

Each time the lever T is dept't:.'ssed by tlw 

hammer-lever If the lever Ax is opcratrnl hy 

a spring 5, secured to the bracket-arm 30, a111l 120 

is raised at the end opposite to the lcve1· 'I'

sists in the knowledge of the position into 

which the/ointer O, the pin Ka, and the irregulator is to be placed at the printing of 

the first letter or figure in recopying the crypS togram into clear writing. To facilitate this,· 

the boxes or. cases H' and II2 are provided 

around their periphery with a double scale 

(see Figs. 4 and 10) having as many divisions 

as there are types in the machine. Those di- 10 visions are marked "R" and" L" and are 

numbered from left to right in one circle (the 

"R" circle) and from right to left in the other 

or "L"circle. The number of divisions in these 

peripheral scales agree with the number of di15 visions in the engraved dial beneath the 

pointer aJ, and the key of the machine is a 

numberof each scale or dial and the"R" or"L" 

(right or left) position at which the ciphers 

were written. 

?o The operation of the machine in writing 

the cryptogram is substantially as follows: 

An official, for instance, desiring to send a 

cryptogram sets the pin k2 to "L," the hand or 

pointer 0 to "10" upon the peripheral scale L, 2 5 and sets the pointer d2 to ''10" upon the circular 

dial; when the key will be"lOL 10." With the 

instrument thus set the official writes out a 

cryptogram, the first word of which, for illustration, is "Paris," and in so doing brings 

30 the pointer successively to the letters of this 

word on the disk II and depresses the handstem M, operating the mechanism, to give the 

impression upon the paper ribbon. The word. 

"Paris" is not impressed on the ribbon, but 

35 th!) cryptogram" C L H D 3" is impressed, 

which is eminently unintelligible. This is 

sent with the key to its destination, and the 

receiver, who has a similar machine to the 

·sender, sets his instrument upon the key "10 

40 R 10," the 1mme in numbers, but the opposite 

in position to the key on which these characters were madL. With the instrument thas 

set the receiver uses the characters "CL HD 3" 

received, and the word ''-Paris" is written out 

45 on the paper. Thus, for instance, the sender 

may use the key "5 L 15" and print a message, 

beginning with "New York" with the characters "K Q Y U \-V E B," and send the same, 

and the receiveF, knowing the kP.y and setting 

50 his similar machine at" 5R15" and using the 

characters sent, will print off "New York." 

Thus a message of any length can be written 

to form the cryptogram. During the writing 

out of a message by the successive depres55 sions of the hand -stem and the operations 

effected thereby, the pointer 1l2 is moved a 

point for each depression of the hand-stem 

l\'1 bv the movement of the lever O', pawl g', 

and .wheel d. This movement also operates 

60 the pawl g, and the skirt or rim cl' moves with 

the wheel d beneath the edge of the pawl g, 

at intervals 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, 

55 engage, and operate said teeth with each 

movement of the lever O' an<l in unison with 

the wheel d nn1il the skirt <7' again comes beneath the pawl g and lifts the same away 

from said teeth. The pawl g will thcen move 

idly over the face of. the skirt until the next 70 

opening therein comes beneath the pawl. 

The movement by the pawl g of the teeth of 

the wheel c operates and shifts the pointer.O, 

one letter for each tooth, in one direction 

through the intervention of the wheels a and 75 

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 0. It will thus be seen that while 

writfog out a cryptogram the pointer 0 will 8o 

thus be irregularly and progressively shifted as the writing of the' message proceeds, 

the pointer getting progressively farther away 

from the type representing the letter indicated by the pointer 0 upon the lettered ring 8.; 

D. Now, when the corresponding machine 

is set to the key to write off the cryptogram 

in readable characters the same irregular 

and progressive shifting of the pointer 0 

takes place in a corresponding manner, but 90 

in the opposite direction, so that the proper 

letters are printed by following out the character of the cryptogram. 

,.'.)The above-described machine may be completed, as shown in Figs. 10 and 13, by -95 

mear.s of the addition of a second series or 

rang-e of types J', placed concentrically to the 

first one and intended to render the cipherwriting of the machine still more undecipherable. The.lever S being placed as indicated 100 

in Fig. 10, if one depresses the stem M, 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 105 

cipher-writing a second letter or figure, the 

purpose of which is merely to render the 

cryptogram still more undecipherable. Ac-· 

cording to the convention between the sender 

and receiver of the cryptogram, the decipher- 110 

ing will take place by first canceling either 

each first or each second lett~r or figure of 

the cryptogram, according as those letters 

forming the very text have been· printed 

with the. types J or with the types -''· 1'he 11 s 

word "Paris" will be written either, for instance, "P I A K R U I T S W," and will be 

deciphered in canceling the second and each 

alternate letter P 1 AK R \J" I~ SW; or it 

may be written "I P K A U R T I 'V S," and 120 

will be deciphered by canceling the first and 

each alternate letter i P K A tr R ~ I W: S. 

If one combines now this latter system of 

cryptography with the above-described one, 

which is quite the same for the machines 125 

with double range of types as for those with 

only one range of types, one obtains a cryptograph which offers the utmost degree of undecipherability. The indicator or ring dial 

D must of course be double when the ma- 130 

chine comprises a double range of types; bnt 

in view of having only one range of letters or 

fignrcs shown at a time npon said ring-dial

painted upon a ring-slider P', placed un'derneath a ring P, provided with suitable open- in~ in which appear the letters and figures 

of the ring-slider P'. According to the posi5 tion into which the l&tter is placed by means 

of the pin or bolt p, the openings of P will 

show either the letters or figures corresponding to the types J or the letters or figures corresponding to the types J'. The ring J is pro- 10 vided with a circular projection bearing npon 

a corresponding recess of the disk II, and the 

ring J' is provided with a circular projection 

bearing upon a correspondin~ recess of the 

ring J. It appears, therefore, that the ring 

15 J is free to be turned with regard to the disk 

H and that J' is free to be turned with regard 

to the ring J. As !'hown in. Figs. 10 and 

11, those rings J and J' are provided with 

holes or recessesj2 andj3, C'orresponding to the 20 types, and to the disk II there are affixed two 

springs j and .i', provided with suitable projectioni;i, which engage into the holes or recessesj2 j3. The rings of types .T and J' may 

be displaced at will with regard to each other 

25 and with regard to the disk II; but the springs 

j andj' allow of maintaining the same into a 

determinated position with regard to said disk. 

In view of having at will either only the types 

of the ring J or only those of the ring J' 

30 printed the support or bearing of the paperrollers and of the levers R, S, and T may be 

displaced by hand upon the base A, so as to 

assume either of the three positions shown 

in Figs. 12, 10, and 13. In the first one, 

35 the hammer S presses the paper ribbon only 

against the types of the ring J, in the second 

one the hammer S presses the paper ribbon 

against the types of both rings J and .T' at a 

time, and in the third the hammer S presses 

40 the paper ribbon only against the types of the 

ring J'. When both types ai:e printed together, the paper ribbon must be advanced 

twice as much as when only one type is 

printed. With that end in view the lever R 

45 is provided with a projection r', upon which 

the hammer-lever U strikes in the middle position of the paper- bearer, Fig. JO, and this 

causes the pawl r to turn the ratchet-wheel w 

two teeth at a time, while it is only turned . 50 one tooth when the hammerU strikes in front 

of or behind the projection r'. 

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 

55 wind up in the form of a Yery small roll the 

printed cipher message. A knurled wheel x is. located in the base A and projects slightly 

beyond the circumference of the latter, so as 

to be easily turned by the finger. Saicl wheel 

60 x carries a gear-wheel z, tlrnt acts upon a pinion?', the slotted stem z2 of which pinion projects out of the upper face of .the base A. If 

one end of the paper ribbon upon which the 

cipher is printed is placed into the slot of the 

65 stem z2 and if the knurled wheel x is then rotated, the paper ribbon will be rapidly wound 

up on the said stem z2 into a very small compass and it is easily withdrawn, and in this 

small compass transported in any desired 

manner to its destination. 70
