A is the base of the machine into which may be inserted a hectographic paste B
of kind whatever, intended to multiply at will the writings printed with the
machine in cause, the inking-ribbon of the same being provided with a suitable
hectographical or autographical ink. CC are two pillars fixed to the base A and
o which is hinged the ring D which bears moreover upon a third pillar E having
spring-clasp F by means of which said ring is held upon the pillar E; in opening

page_text: said clasp one may allow said ring to be lifted like a cover when it is wanted to
look at one of the inner parts of the machine.
The ring D bears a lower fixed case G, in which is placed a movable ring-
piece I bearing the types. The case G is provided with suitable openings to
allow the movement of the mechanism described below.
The disc H, bearing the types J as already stated, is further provided with a
horizontal teethrange I in which gears a bolt K having a small roller at its
extremity in view of insuring its engaging into the intervals of the teeth of L, each
time the said bolt is pressed outwardly by the projection m of the handstem M
(Fig. 2 and 5) against which it is constantly pressed by a spring L.
The purpose of this disposition is to render the disc H temporarily immorable
whilst a letter is printed. The nave h of the disc H being movable in the case G,
the disc H may be turned in any direction when said bolt K is at rest. A ring hi
prevents the lifting of the disc H out of its place. The revolving of the disc H is
caused by means of a square part of the handstem M which engages into the
ring N fixed to the nave of the disc H, and into which it may be depressed
axially from the position shown in Fig. 1 to that shown in Fig. 2. If one turns
the handstem M the disc EI is also revolved. The said stem M inay be withdrawn
in view of having the machine suitable to be put in one's pocket. As shown in
Fig. 9 said stem contains a turn-screw intended to be used when the machine is
to be unmounted. On the nave h there is placed a hand or pointer O which is free
to turn, and which is intended to determine, as it will be shown below, the letter or
figure of the ringshaped indicator or dial D, (Fig. 5) which will be printed accord-
ing to the position of the disc H, when the stem M is depressed.
The hand or pointer O is combined with a mechanism which will be described
below, and which is especially intended to produce the cypher-writing.
But, in
view of having the printing or writing mechanism readily understood we will
for a moment, suppose said hand or pointer O fixed to the disc H.
The base-plate A is provided with three vertical walls Q', Q" and Q to which
are pivoted the rollers which guide the paper-ribbon upon which one is printing
and the levers R, S and T. The lever R is acted upon by the hammer-lever
and intended to cause the advancing of said paper-ribbon after each printing.
The hammer-lever S, the one end of which is depressed by the hammer-lever U
when the stem M is depressed, presses with its other end the paper-ribbon V
against the lower surface of the types J of the ring H and the lever T is intended
to produce the advancing of the inking-ribbon which passes between the paper-
ribbon and the types. Those three levers, acted upon by suitable springs, are all
acted upon by the hammer-lever U which is pivoted in to the base-plate A
and acted upon by the stem M each time the latter is pressed to bottom into
the machine. By fulfilling such depression one causes at a time the lifting of the
paper-ribbon against the types J by means of the lever S and one raises the
click to lever R so as to cause the wheel to turn of one tooth when one
abandons the stem M, the lever R being raised by its spring. The wheel w drives
the roller W which is recovered with india-rubber and which presses the paper
against the roller X, so that the paper-ribbon V advances, after each printing, of a
predeterminated length. Said paper-ribbon is wound around a small pulley or
drum Y fixed to a slider y which slides in a suitable slot of the base A. When the
machine is not used one may lay down the pulley Y and lodge the same as
shown in Fig. 1 between the base-plate A and the top of the machine. When one
wishes to write with the machine the slider y is thrown outward and the pulley Y
raised upward as shown in Fig. 2. A. suitable spring, gearing into suitable notches
of the slider y maintains the latter in the one or in the other of those two positions.
From the pulley or drun Y, which bears a sufficient reserve of paper-ribbon for
writing a great deal of letters, the paper-ribbon V passes beneath a roller Z and
over the head-piece of the lever S and over the roller W and then between the
latter and the roller X which it surrounds nearly entirely and from which it leaves
the machine as shown in Fig. 2. This figure shows moreover a vertical section of

page_text: the peculiar form of the basis of the support of the rollers W, X and Z, which
form is intended to force the paperribbon to follow the way described above, as
shown in Fig. 2, when one engages its end first under the roller Z and then between
the rollers W and X.
As it will be understood from the above description, if one places the band or
pointer O upon a letter or figure of the indicator D, for instance upon the Figure 7
and if one depresses then the stem M to bottom into the machiue, one causes first
the bolt or slider K to be pressed into the teeth range of the ring H, which is
thereby made motionless, and one causes moreover the lever S to throw the paper-
ribbon against the type 7 of the ring H, the inking-ribbon being interposed
between the type and the paper like in other typewriters. Said inking-roller is
supported by two drums A' and A" the one of which is combined with a ratchet-
wheel, acted upon by the above mentioned lever T. The machine is moreover
provided with a cryptographical disposition, by means of which the hand or
pointer D may be displaced from time to time with regard to the types
of the ring H, either on the left or on the right when the machine is printing.
The mechanism which realizes this function is more peculiarly shown in the
Fig. 1, 2, 6, 7, 8 and 8. To the nave of the disc or ring H is affixed by means of
a ring N, a cylindrical box H' upon which is fixed a second cylindrical box H" by
means of screws h'. The Fig. 6 is a view from below and Fig. 7 a top-view of the
box H, and the Fig. 11 shows a top-view of the box H'.
The above-mentioned hand or pointer O which is free to turn about the nave h
of the disc H, is fixed to a gear-wheel b into which alternately gears either a
pinion a or a pinion a' which are pivoted to a swing-bridge or rocker k (Fig. 6).
The pinion a being constantly in gear with a wheel c, one will cause the wheel b
to be turned with regard to H, either on the left or on the right in turning the
wheel e, according as the pinion has been put directly into gear with 6 or as the
rotation is transmitted from c to 6 by means of both pinions a' and a
This con-
nection and disconnection will be operated by means of a lever k having a pin "
which projects out of a seginental slot of the case or box H (Fig. 7 & 11).
letters R and L, which are engraved at the ends of said slot, indicate if the lever k
is placed for right or left motion of the wheel b.
The
The wheel c, which is pivoted between the boxes Hand H", is double (Fig. 8)
having, beyond the teethrange which is in gear with the pinion a¹ a range
of ratchet-teeth acted upon by a click a fixed to a lever Of which is pivoted
at o' to the box or case H" and acted upon by a spring o". On the other
hand, the wheel c is combined with a wheel d, provided with a cylindrical rim d',
the latter recovering like a mantle the ratchet-teeth of c, is provided with irregular
openings or out-cuts and is intended to momentarily prevent the gear of click g
with the ratchet-teeth of c. Those out-cuts or openings are made so as to discover
sometimes one sometimes two or more of those ratchet-teeth of wheel c.
ratchet-wheel d is acted upon by a second ratchet which is also pivoted to
the lever O and the latter bears a support e with roller el which is pressed
toward the center of the machine by a spring o". The stem M. is provided with a
projection m playing like a wedge and passing through a suitable out-cut n¹ of
the ring N. Said projection repulses the roller and support e cach time
the stem M is depressed, as shown in Fig. 2 and causes thereby a backward-
oscillation of the lever O¹.
The
When the stem is lifted again the lever O¹ falls back into its first place,
under the action of the spring o". Each oscillation of the lever 0 causes the
ratchet-wheel d to be turned of one tooth and the rim or mantle making part
of d is consequently displaced at every oscillation of lever 01, that is to say: at
every depression of the stem M which happens at each printing of a letter or
figure. The click is also acted upon by each oscillation of the lever O₁ and
it sometimes acts upon a ratchet-tooth of c but sometimes abuts against a full
part of the rim or mantle d¹; in the first case it causes the wheel c to be turned
of one tooth which acts upon the pinion a or a¹ and causes the wheel b

page_text: E
"
consequently and the pointer O to be turned of one tooth on the left or on the right,
according to the position: "L or "R" in which one had placed the pin ".
In the second case the ratchet & turns alone and the pointer O is not displaced with
regard to H. The displacing of the pointer O with regard to the type-ring. or
disc E is therefore determinated by the out-cuts or openings of the rim or mantle.d²,
which might be called the "irregulator" and which may be varied at will provided
those machines which are to correspond with one another (the machine of tho
sender and that of the receiver of cypher-writings) have one and the same
irregulator."
The key of a cryptographical communication written with such a machine having
a determinated "irregulator" consists in the knowledge of the position into which
the pointer O, the pin and the "irregulator" d' is to be placed at the printing
of the first letter or figure in recopying the cryptogramme into clear writing. To
facilitate this the boxes or cases H and H" are provided with a double scale
having as many divisions as there are types in the machine. Those divisions are
numbered from left to right in the one and from right to left in the other case or
box. If, for instance, the key is: 25 L 30 one will have to place the lever k¹or
pin upon "L" and the pointer O upon the division 25 on the left of zero.
The figure 30 of the key gives the position of the "irregulator" d'. One places
the hand, fixed to the axis of which projects out of the top-plate of the
box H, upon the division 30 of the small dial or circular scale surrounding said
projection of the axis d.
In recopying then the cryptogramme received one will automatically write into
clear writing the original text which the sender has written with a corresponding
machine and with the key: 25 R 30.
The above described machine may be completed as shown in the Fig. 10 and 13
by means of the addition of a second series or range of types J' placed concentrically
to the first one.
·
The system of cryptography is quite the same for the machines with double range
of types as for those with only one range of types, one obtains a cryptography which
offers the utmost degree of undecypherability. The indicator or ring-dial D must
of course be double when the machine comprises a double range of types; but in
view of having only one range of letters or figures shown at a time upon said ring-
dial those letters and figures are engraved or painted upon a ring-slider P₁ placed
underneath a ring P provided with suitable openings in which appear the letters
and figures of the ring-slider P. 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 figures corresponding to the types Jor the letters or figures
corresponding to the types . The rings of types J and J' may be displaced
at will with regard to each other and with regard to the disc M but
the springs and allow to maintain the same into a determinated position
with regard to said disc. In view of having at will either only the types
of the ring J or only those of the ring J printed, the support or bearing of the
paper-rollers and of the levers R, S and T may be displaced upon the basc A. so as
to assume either of the three positions shown in the Fig. 12, 10 & 13. In the first
one 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 Jat a time and in the third the hammer S presses the paper-ribbon
only against the types of the ring J'. When both types are printed together the
paper-ribbon must be advanced (displaced) twice as much as when only one type is
printed. To that effect the lever is provided with a projection upon which
strikes the hammer-lever U in the middle position of the paper-bearer (Fig. 10)
and this causes the click to turn the ratchet-wheel w of two teeth at a time whilst
it is only turned of one tooth when the hammer U strikes in front of or behind the
projection +1.
;
The machine shown in Fig. 12 is further provided with a small reel located in
the base A and intended to easily wind up in form of a very small roller, the

page_text: C
writing printed with the machine. A whirled wheel is located in the base A and
projects slightly on the circumference of the latter so as to be easily turned by the
finger. Said wheel bears a. gear-wheel y arting upon a pinion z the slotted
stem z of which projects out of the upper face of the base A. If one engages the
extremity of the paper-ribbon upon which one has written (or printed) into the slot
of the stem 2' and if one turns then the whirled wheel, the paper-ribbon will be
rapidly wound up on the said stem z' from where it is easily withdrawn.
In the communications (cryptograms) written by means of the above described
machine one may replace the white spaces separating every two words from one
another by a letter, figure, or accent which will be indicated in the key but which,
in the cypher-writing, will be represented by varying types so as to still increase
its undecypherability.

COMPLETE SPECIFICATION.
Improvements in Type-writers, particularly applicable for Writing
in and Translating Cypher or Codes.
1, CZESLAW RYMTOWTT-PRINCE, Manufacturer, of 1 Rue Necker, Geneva,
Switzerland, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement :-
#
The main object of the invention is to allow to officers to exchange cypher-
writings which are absolutely undecypherable to all those who do not at a time
possess the key" of the writing and a machine similar to that with which the
cryptogram has been written. These cypher writings have moreover the advantage
of being of so small dimensions that they may very easily be dissembled by those
who are commissioned with their transmission.
The said cypher-writer prints the letters upon a very thin paper-ribbon which
may be pasted upon a sheet of paper by the receiver, of the writing, if desired.
The machine is of so small a volume (about 34 inch in diameter and 1 inch in
height) that it may easily be put into one's pocket, and nevertheless all its parts
are constructed with such a solidity and precision that its good working is insured,
even if used by unskilled people.
The machine is further provided with a disposition allowing to multiply at will
the communication printed with the machine, thus allowing to send the same to
more than one person without printing it more than once, and further with a
mechanism allowing to roll up to a very small roller the paper-ribbon which is to
be sent off.
In the drawings accompanying the Provisional Specification
Figure 1 is a vertical section of the machine at rest.
Figure 2 is a similar section of the machine at the very moment when a letter or
type is printed.
Figure 3 is a plan view of the machine in which the whole upper part, except the
rollers, bearing the inking-ribbon, has been cut away.
Figure 4 is a front view of the machine and Figure 5 a plan view with partial
section.
The Figures 6, 7, 8, 8 and 9 show details of the same machine.
Figure 10 is a section and Figure 11 a plan view of the same machine provided
with a double range of types.
The Figures 12 and 13 show detached parts of the machine shown in the
Figures 10 and 11.
In all the figures the same letters refer to the same pieces.
A is the base of the machine into which may be inserted a hectographic paste B
of any kind whatever; intended to multiply at will the writings printed with the

page_text: machine in cause, the inking-ribbon of the same being provided with a suitable
hectographical or autographical ink. CC are two pillars fixed to the base A and
to which is hinged the ring D which bears morcover upon a third pillar E having a
spring-clasp F by means of which said ring is held upon the pillar E; in opening
said clasp one may allow said ring to be lifted like a cover when it is wanted to
look at one of the inner parts of the machine.
The ring D bears a lower fixed case G, in which is placed a movable ring-
piece H bearing the types. The case G is provided with suitable openings to allow
the movement of the mechanism described below.
The disc H, bearing the types J ns already stated, is further provided with a
horizontal teeth range 1 in which gears a bolt K having a small roller at its
extremity in view of insuring its engaging into the intervals of the teeth of I, each
time the said bolt is pressed outwardly by the projection of the hand stem M
(Figures 2 and 5) against which it is constantly pressed by a spring L. The
purpose of this disposition is to render the disc H temporarily immovable whilst a
letter is printed. The nave h of the disc H being inovable in the case & the
disc H may be turned in any direction when said bolt K is at rest. A ring h¹
prevents the lifting of the disc H out of its place. The revolving of the disc H is
caused by means of a square part of the handstem M which engages into the
ring N fixed to the nave of the disc H, and into which it may be depressed
If one
axially from the position shown in Figure 1 to that shown in Figure 2.
turns the handstem M the disc H is also revolved. The said stem M may be
withdrawn in view of having the machine suitable to be put in one's pocket.
As shown in Figure 9 said stem contains a turn-screw n intended to be used
when the machine is to be unmounted. On the nave h there is placed a hand or
pointer which is free to turn and which is intended to determine, as it will be
shown below, the letter or figure of the ring shaped indicator or dial D (Figure 5)
which will be printed according to the position of the disc H, when the stem M is
depressed.
The hand or pointer O is combined with a mechanism which will be
described below, and which is especially intended to produce the cypher-writing.
But in view of having the printing- or writing-mechanisin readily understood
we will for a moment, suppose said hand or pointer O fixed to the disc H.
The base-plate A is provided with three vertical walls Q, Q" and Q to which
are pivoted the rollers which guide the paper-ribbon upon which one is
and the levers R, S and T. The lever R is acted upon by the hammer-lever
and intended to cause the advancing of said paper-ribbon after each printing.
The hammer-lever S, the one end of which is depressed by the hammer-lever Ű
when the stem M is depressed, presses with its other end the paper-ribbon V
against the lever surface of the types J of the ring H and the lever T is intended
to produce the advancing of the inking-ribbon which passes between the paper-
ribbon and the types. Those three levers, acted upon by suitable springs, are all
acted upon by the hammer lever U which is pivoted in to the base-plate A
and acted upon by the stem M. each time the latter is pressed to bottom into the
machine. By fulfilling such depression one causes at a time the lifting of the
paper-ribbon against the types J by means of the lever S and one raises
the click of lever R so as to cause the wheel w to turn of one tooth when one
abandons the stem M, the lever R being raised by its spring. The wheel w drives
the roller W which is covered with india rubber and which presses the paper
against the roller X, so that the paper-ribbon V advances, after each printing of a
predetermined length. Said paper-ribbon is wound around a small pulley or
drum Y fixed to a slider y which slides in a suitable slot of the base A.
When the machine is not used one may lay down the pulley Y and lodge the
same as shown in Figure 1 between the base plate A and the top of the machine.
When one wishes to write with the machine the slider y is thrown outward and the
pulley raised upward as shown in Figure 2. A suitable spring gearing into suitable
notches of the slider y maintains the latter in the one or in the other of those two

page_text: positions. From the pulley or drum Y, which bears a sufficient reserve of paper-
ribbon for writing a great deal of letters, the paper-ribbon V passes beneath a
roller Z and over the head-piece of the lever S and over the roller W and then
between the latter and the roller X which it surrounds nearly entirely and from
which it leaves the machine as shown in Figure 2. This figure shows moreover a
vertical section of the peculiar form of the basis of the support of the rollers W, X
and Z, which form is intended to force the paper-ribbon to follow the way
described above, and shown in Figure 2, when one engages its end first under the
roller Z and then between the rollers W and X.
As it will be understood from the above description, if one places the hand or
pointer O upon a letter or figure of the indicator D, for instance upon the Figure 7
and if one depresses then the stem M to bottom into the machine, one causes first
the bolt or slider to be pressed into the teeth range of the ring H which is
thereby made motionless, and one causes moreover the lever S to throw the paper-
ribbon against the type 7 of the ring H, the inking-ribbon being interposed
between the type and the paper like in other type writers. Said inking-ribbon is
supported by two drums A and A" the one of which is combined with a ratchet-
wheel, acted upon by the above mentioned lever T. The machine is moreover
provided with a cryptographical disposition, by means of which the hand or
pointer O may be displaced from time to time with regard to the types of the
ring H, either on the left or on the right when the machine is printing. The
mechanism which realizes this function is more peculiarly shown in the Figures 1,
2, 6, 7, 8 and 84. To the nave of the disc or ring H is affixed by means of a
ring N, a cylindrical box H¹ upon which is fixed a second cylindrical box H" by
means of screws . The Figure 6 is a view from below and Figure 7 a top view
of the box H, and the Figure 11 shows a top view of the box H³.
The above mentioned hand or pointer O which is free to turn about the nave h
of the disc H, is fixed to a gear wheel into which alternately gears cither a
pinion a or a pinion a¹ which are pivoted to a swing-bridge or rocker k (Figure 6).
The pinion a being constantly in gear with a wheel c, one will cause the wheel b
to be turned with regard to H, either on the left or on the right in turning the
wheel c, according as the pinion has been put directly into gear with or as the
rotation is transmitted from c to b by means of both pinions a¹ and a.
This con-
nection and disconnection will be operated by means of a lever & having a pin
which projects out of a segmental slot of the case or box H¹ (Figures 7 and 11).
The letters R and L which are engraved at the ends of said slot indicate if the
lever K is placed for right or left motion of the wheel b.
The wheel c which is pivotted between the boxes H' and H, is double
(Figure 8) having, beyond the teeth range which is in gear with the pinion a¹, a
range of ratchet teeth acted upon by a click g fixed to a lever O¹ which is pivoted
at 0¹ to the box or case H" and acted upon by a spring O". On the other hand,
the wheel c is combined with a wheel i, provided with a cylindrical rim, the
latter recovering like a mantle the ratchet teeth of c, is provided with irregular
openings or out cuts and is intended to momentarily prevent the gear of click y
with the ratchet teeth of c. Those out cuts or openings are made so as to discover
sometimes one sometimes two or more of those ratchet teeth of wheel r. The
ratchet wheel dis acted upon by a second ratchet g' which is also pivotted to the
lever O' and the latter bears a support e with roller e which is pressed toward the
centre of the machine by a spring O". The stem M is provided with a pro-
jection m playing like a wedge and passing through a suitable out-cut" of the
ring N. Said projection m" repulses the roller and support e each time the
stem M is depressed, as shown in Figure 2 and causes thereby a backward
oscillation of the lever O'.
When the stem is lifted again the lever O' falls back into its first place, under
the action of the spring O". Each oscillation of the lever O' causes the ratchet
wheel d to be turned of one tooth and the rim or mantle making part of d is
consequently displaced at every oscillation of lever O', that is to say, at every

page_text: "

C
depression of the stem M which happens at each printing of a letter or figure.
The click y is ako acted upon by each oscillation of the lever 0¹ and it sometimes
acts upon a ratchet tooth of c but sometimes abuts against a full part of the rim or
mantle d'; in the first case it causes the wheel c to be turned of one tooth which
acts upon the pinion a or a¹ and causes the wheel & consequently and the pointer O
to be turned of one tooth on the left or on the right, according to the position;
"L or "R" in which one had placed the pin " In the second case the
ratchet d turns alone and the pointer O is not displaced with regard to H. The
displacing of the pointer with regard to the type-ring or disc H is therefore
determinated by the out-ents or openings of the rim or mantle which might be
called the "irregulator" and which may be varied at will provided those machines
which are to correspond with one another (the inachine of the sender and that of
the receiver of cypher-writings) have one and the same "irregulator."
The key of a cryptographical communication written with such a machine
having a determinated "irregulator" consists in the knowledge of the position into
which the pointer O, the pin K' and the "irregulater" is to be placed at the
printing of the first letter or figure in recopying the cryptogramme into clear
writing. To facilitate this the boxes or cases Hand H are provided with
double scale having as many divisions as there are types in the machine. Those
divisions are numbered from left to right in the one and from right to left in the
other case or box. If for instance, the key is: 25 L 30 one will have to place the
lever or pin upon "L" and the pointer O upon the division 25 on the left of

projection of the axis d.

In recopying then the cryptogramme received one will automatically write into
clear writing the original text which the sender has written with a corresponding
machine and with the key 25 R 30.
The above described machine may be completed as shown in the Figures 10
and 13 by means of the addition of a second serie or range of types
concentrically to the first one.
JY placed
The system of cryptography is quite the same for the machines with double
range of types as for those with only one range of types, one obtains a
cryptography which offers the utmost degree of undecypherability. The indicator
or ring-dial D must of course be double when the machine comprises a double
range of types; but in view of having only one range of letters or figures shewn at
a time upon said ring-dial those letters and figures are engraved or painted upon a
ring-slider P¹ placed underneath a ring P provided with suitable openings in which
appear the letters and figures of the ring-slider P¹. According to the position into
which the latter is placed, by means of the pin or bolt p the openings of P will
shew either the letters or figures corresponding to the types J or the letters or
figures corresponding to the types J'. The rings of types J and J' may be
displaced at will with regard to each other and with regard to the disc H but the
springs and j' allow to maintain the same into a determinated position with
regard to said disc. In view of having at will either only the types of the ring J
or only those of the ring J' printed, the support or bearing of the paper rollers and
of the levers R, S and T may be displaced upon the base A. so as to assume either
of the three positions shewn in the Figures 12, 10 and 13. In the first one 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 J at a time and in the third the hammer S presses the paper-ribbon
only against the types of the ring J. When both types are printed together the
paper-ribbon must be advanced (displaced) twice as much as when only one type is
printed. To that effect the lever R is provided with a projection upon which
strikes the hammer-lever U in the middle position of the paper-bearer (Figure 10)
and this causes the click to turn the ratchet wheel w of two teeth at a time whilst

page_text: it is only turned of one tooth when the hammer U strikes in front of or behind the
projection r².
The machine shewn in Figure 12 is further provided with a small reel located in
the base A. and intended to easily wind up in form of a very small roller, the
writing printed with the machine. A whirled wheel is located in the base A and
projects slightly on the circumference of the latter so as to be easily turned by the
finger. Said wheel bears a gear-wheel y acting upon a pinion z the slotted
stein z¹ of which projects out of the upper face of the base A. If one engages the
extremity of the paper-ribbon upon which one has written (or printed) into the slot
of the stem z¹ and if one turns then the whirled wheel z, the paper-ribbon will be
rapidly wound up on the said stem 2¹ from where it is easily withdrawn.
In the communications (cryptograms) written by means of the above described
machine one may replace the white spaces separating every two words from one
another by a letter, figure, or accent which will be indicated in the key but which,
in the cypher-writing, will be represented by varying types so as to still increase
its undecypherability.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The pulley bearing the paper-ribbon upon which the machine is printing.
2. The slider y bearing the pulley Y.
3. The combination of the rollers W, X and Z with the base plate formed as
shewn in Figure 2, in view of guiding the paper-ribbon.
