I, FERDINAND VON EULENFELD, of 3, Schiffbauerdamm, Berlin, in the
German Empire, Merchant, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a type-writer which is somewhat in the form of a pencil
and which is adapted to be carried in the pocket.
My improved type-writer has a tubular casing having arranged within it an
endless band upon which the letters or characters are formed, the said band
(hereinafter referred to as the type-band) being carried upon suitable rollers inside
the said tubular casing, a spring roller also being provided for the purpose of
maintaining the type-band taut. A second tube, which I term the thruster, slides
telescopically upon the casing, the said thruster being connected with the type-
band through a suitable slot in such a manner that the movement of the thruster
upon the tubular casing causes the movement of the band to bring the required
letter opposite the open lower end of the casing in such a position that when
the casing is pressed upon the paper the said lowermost letter will be printed
thereon.
.
The outside of the casing has marked upon it the letters or characters
corresponding with those upon the type-band and upon the thruster is a rod
carrying a catch adapted to engage with notches formed in the casing opposite to
the said letters whereby when the said catch is in engagement with one or the other
of the notches the thruster will be prevented from moving relatively with the casing
whilst the apparatus is being pressed upon the paper to print. The said rod is
provided near the upper end of the telescopic tube with a thumb-piece which serves
for holding the rod so that its catch is in engagement with one of the said notches;
a spring serves to normally hold the catch out of engagement with the notches.
A spring is also arranged inside the thruster in such a manner as to normally hold
the apparatus extended..
The apparatus is provided at the lower end with spring-feet which normally hold
the type away from the paper whilst the type-band is being shifted. The movement
of the apparatus after each letter is printed may be effected by hand or serrated
travelling wheels are arranged in conjunction with the said feet, which travelling
wheels are acted upon by spring-pawls in such a manner that as the apparatus is
depressed to print a letter the said travelling wheels will be rotated to move the
apparatus the required distance.
The inking of the type-band is effected by means of two inking rollers carried
by springs and arranged in small boxes on the sides of the casing in contact with
the band so that as the band is moved the type thereon will be inked.
To enable the apparatus to be readily packed the feet are made detachable and a
cap is provided for closing the lower end of the case.
The catch herein before referred to is provided with a slot adapted when the
thruster is pressed right down over the casing to engage with a small lug upon
the latter.

page_text: An Improved Type-writer.
I, FERDINAND VON EULENFELD, of 3, Schiff bauerdamm, Berlin, in the
German Empire, Merchant, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention relates to a type-writer which is somewhat in the form of a pencil
and which is adapted to be carried in the pocket.
My improved type-writer has a tubular casing having arranged within it a band,
hereinafter referred to as an endless baud, upon which the letters or characters are
formed, the said band (hereinafter referred to as the type-band) being carried upon
suitable rollers inside the said tubular casing. A second tube, which I term the
thruster, slides telescopically upon the casing, the said thruster being connected
with the type-band through a suitable slot in such a manner that the movement
of the thruster upon the tubular casing causes the movement of the band to
bring the required letter opposite the open lower end of the casing in such a
position that when the casing is pressed upon the paper the said lowermost letter
will be printed thereon.
The outside of the casing has marked upon it the letters or characters corre-
sponding with those upon the type-band and upon the thruster are rods each
carrying a catch adapted to engage with notches formed in the casing opposite to
the said letters whereby when the said catch is in engagement with one or the other
of the notches the thruster will be prevented from moving relatively with the
casing whilst the apparatus is being pressed upon the paper to print. The said
rods are provided near the upper end of the telescopic tube with thumb-pieces
which serve for holding the rods so that one of the catches is in engagement with
one of the said notches; springs serve to normally hold the catches out of engage-
ment with the notches. A spring is also arranged inside the thruster in such a
manner as to normally hold the apparatus extended.
The apparatus is provided at the lower end with spring-feet which normally hold
the type away from the paper whilst the type-band is being shifted. The
movement of the apparatus after each letter is printed may be effected by hand:
or travelling wheels are arranged in conjunction with the said feet, which travelling
wheels are acted upon by spring-pawls in such a manner that as the thruster is
allowed to rise after a letter has been printed the said travelling wheels will be
rotated to move the apparatus the required distance.
Instead of observing the characters marked upon the tubular casing I may
employ a device which I call the indicator by which the letter or character at
the bottom of the type-writer in a position to be printed is pointed out on a dial
by a pointer.
The inking of the type-band is effected by means of two iuking rollers carried by
springs and arranged in small boxes on the sides of the casing in contact with the
band so that as the band is moved the type thereon will be inked.
To enable the apparatus to be readily packed a cap is provided for closing the
lower end of the case.
The catch herein before referred to is provided with a pin adapted when the
thruster is pressed right down over the casing to engage with a small slot in
the latter.
To enable my, invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :--

inside the tubular casing a. dis the outer tube or thruster which slides
telescopically on the casing a and which is connected with the type-band & through-
a slote by means of a pin f. a is the portion of the casing upon which are
inscribed the characters which the apparatus is capable of writing the said
characters being arranged in four vertical rows as shewn in Figure 7. In the said'
figures only a few of the characters are shewn in each row.
9, go, and ho are the rod's pivotted on the outside of the casing & the rods g
and being solid and passing through the rods 9° and 1° respectively which are
hollow as shewn in Figures 1 and 2. The said rods g, 9º, h and hº are provided at
their upper ends with the thumb-pieces i, j, k,l respectively whilst the lower ends
are respectively provided with the catches m, n, o, p- adapted to engage with the
notches q, q formed in the casing a when the thumb-pieces i, j, k, l'are depressed.
The catches m, n, o, p are of different lengths so that when the thruster d' is
depressed they will each move over a row of characters, the thumb-pieces being
inscribed with the first and last characters of the row over which their respective
catches move.
The said catches are also pointed at their outer ends so that when
any one of them is opposite a character the tooth of the catch will be opposite a
notch 9 corresponding with a type on the type-hand 6 similar to such character.
r; rare springs arranged upon the thumb-piece- and serving to normally hold
the catches out of engagement with the notches q; 9.
In my Provisional Specification 1 referred to the use of a single rod but I
preferably use the arrangement above described which does not require such an
accurate regulation of the movement of the thruster and by which
to classify the characters.
am enabled'
⚫s is the spring arranged in the interior of the thruster d' so as to normally Hold
the apparatus extended and t, t are the spring feet adapted to hold the type away
from the paper when the type-band is to be shifted to bring another type into
position. These spring feet t, t are connected together by pins u, u which pass
through vertical slots u', u' in the plates v, v carrying the roller cº of the type-
band; a spring w bearing at the top against a stop w' fixed to the casing a and at

page_text: the bottom against the upper pin u keeps these spring feet normally extended.
The spring feet are provided at their lower ends with travelling wheels of gutta-
percha or other suitable substance or with serrated wheels a, adapted to effect
the forward movement of the apparatus by the upward movement of the thruster d
after each letter is printed, by means of the ratchet wheels-y, y fixed to the inner
side of the wheels, and the spring-pawls, engaging with the said ratchet
wheels. ** are detent pawls engaging with the ratchet wheels y, y.
al, are the inking rollers carried in the boxes b', on the casing a and held
against the type-band by springs c¹, c¹.
º, 2º are tables for supporting the type-band under the pressure of the inking
rollers a¹, a¹ the said tables being carried by plates supported upon the upper pin u.
z is an additional guide roller for the band b carried by the plates supporting the
tables º, 2º.
To enable the apparatus to be readily packed the tooth of the catch o is notched
as shewn in Figure 8 so as to enable it to be engaged with a slot d¹ in the casing a
when the tube d is moved down thereby preventing the said tube from being
extended by the springs, and the lower end of the apparatus can be closed by the
cap illustrated by Figures 5 and 6.
The apparatus is employed as follows:-The spring feet t, t are placed on the
paper and the thruster is pressed down until the proper catch is opposite the
character it is desired to print. The thumb-piece corresponding to the catch is
then depressed thereby locking the catch in the slot 7 corresponding to the
character to be printed. The downward movement of the thruster has brought
the desired character on the type-band at the bottom point of the same and on
further pressing down the thruster the tubular casing and type-band are carried
with the same thereby printing the character on the paper. The thruster is now
allowed to rise and the apparatus is carried forward on the paper by means of the
travelling wheels which are actuated in the manner hereinbefore described and
the apparatus is in a position for printing another character.
Figures 10 and 11 shew the device which I call the indicator adapted for
shewing at a glance when the type which it is desired to print on the paper is in
the correct position at the bottom of the apparatus for being printed. This device
consists of a light frame e' to which is pivotted a pointer fl adapted to move over
the face or dial e° of the indicator fitted in. the frame e¹ and on which are
inscribed the characters to be printed. The frame is attached to the type-writer
apparatus by means of two rods g', g¹ which pass into eyes ', h¹ on the casing a
of the type-writer. Motion is imparted to the pointer by means of a train of
gear wheels oue of which wheels is attached to a pulley around which the cord
passes while the other wheel is attached to a worm gearing with a worm wheel
upon the pointer arbor and of an endless cord j' which cord passes round pulleys
and carries a plate having a hole engaging with a pin on the thruster d
thereby partaking of the motion of the latter. It will be obvious therefore that
by suitably arranging the letters or characters on the indicator or dial the
pointer would point to the letter which is in a position to be printed upon the
paper.
The indicator is preferably so constructed that it can be folded compactly
together the dial eº being first disengaged and folded along the dotted lines so
as to take up a small compass.
Figures 12, 13 and 14 shew an arrangement which I advantageously use to cause
the type-writer to move forward in a straight line. It consists of a curved spring
provided with an eye or socket m' which can be inserted over the ends of either
of two projections n' on the spring feet t, t of the type-writer as shewn in
Figures 13 and 14 and having wheels or rollers o¹, o' at its extremities. These
two wheels in conjunction with the two wheels x, x attached to the spring
feet t, t cause the type-writer to move forward in a straight line.
Figures 15 and 16 shew another arrangement for effecting the same result which
arrangement consists of a rule p' of light material, such as aluminium, one edge

page_text: of which is bent up at right angles as shewn, and of a guide y¹ provided with a
socket for attachment to one of the projections n' and with hooks r¹ adapted to..
slide on the turned up edge of the rule pl.
Figures 17 and 18 shew another arrangement for obtaining the same result.
It consists of a flat plate s¹ (two of which are used) provided with sockets m' for
attachment to the projections the said plate having a straight lower edge
adapted to bear upon the paper being written upon.
Figure 19 shews a slotted plate of aluminium or other suitable light material
adapted to be used in conjunction with the arrangement shewn in Figures 17
and 18. The slots t', are of such a width that the guides ',, Figure 17,
when fitted to the projections n' on the spring feet of the type-writing apparatus
can just fit into them, whereby the type-writer when operated is guided in a
straight line and equal spacing of the lines is obtained.
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. In a type-writer a tubular casing within which a band is arranged upon
rollers and upon which the letters or characters are formed, a second tube or
thruster sliding telescopically on the tubular casing. and connected to the band
through a slot in the said casing whereby the band partakes of the movement
of the thruster over the casing and means whereby the movement of the thruster
can be stopped at any desired point so that a particular character may be printed
on the paper, substantially as described.
2. In a type-writer of the kind described in Claim 1 providing the tubular
casing with slots and with characters opposite the slots and pivotting to the
thruster rods carrying spring catches at their lower ends and thumb-pieces at their
upper ends, the said catches being adapted to take into the slots in the tubular
casing when the said thumb-pieces are depressed whereby the movement of the
thruster on the tubular casing is arrested at any desired point, the said tubular
casing being provided with spring feet to keep the type band normally out of
contact with the paper, substantially as described.
3. The combination with a type-writer of the kind described in Claim 1 of a
dial on which are inscribed the characters to be printed corresponding to the
characters on the type-band and of a pointer adapted to move over the dial and
so arranged that it moves with the type-band and points to that character on the
dial which is in a position to be printed by the type-writer, substantially as
described.
4. The combination with a type-writer of the kind described in Claim 1 of the
devices for guiding the same hereinbefore described and illustrated in Figures 12
to 19 of the drawings.
5. The manufacture and use of the improved type-writer consisting of the parts
constructed and combined substantially as hereinbefore described and illustrated in
the accompanying drawings and operating as and for the purpose set forth.
