Improvements in Inking Apparatus for Typewriting Machines.
I, ANGELO BEYERLEN, of 10, Eugenstrasse, Stuttgart, Wurtemberg, in the
Empire of Germany, Civil Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
The present invention relates to an improvement in "interchangeable
auxiliary" inking apparatus for type writing machines and has for its object
to enable a ribbon of great length, for example, from 12 to 15 metres to be used
and to enable either the ribbon together with the spools or the whole auxiliary
inking apparatus to be fixed on the machine or removed therefrom at any time.
With the auxiliary inking apparatus hitherto in use with typewriting
machines there existed the drawback that generally only a short piece of inking
ribbon could be used. The ribbon itself was stretched by a spring fixed in the
spool. This prevented the use of ribbons made from paper, which is however
possible by means of the present improved arrangement, because with this new
method the paper ribbon does not require to be stretched and in consequence
is not liable to be torn.
With this new "interchangeable" auxiliary inking apparatus the following
novel aims are therefore fulfilled:-
(1) The new auxiliary inking apparatus can be fixed to any typewriting
machine, provided with hard type and can be applied without prejudice to the
inking apparatus already attached to the machine in question. As an example
the invention will be described as applied to a Yost machine;
(2) The new auxiliary inking apparatus can be fixed to or removed from the
machine at any time according to requirement;
(3) The auxiliary inking apparatus permits of the instantaneous insertion of
spools with ribbons of any desired colour and consequently admits of a quick
change of the colour, as well as allowing of the inking material of the inking
apparatus found originally in the machine being exchanged for that of the new
auxiliary inking apparatus, which is especially valuable for the hektograph
and lithography;
(4) In connection with machines having inking pads and automatically inked
type, it permits of the use at the same time of both kinds of inking, namely,
the one by means of the inking pad and the one by means of a paper or textile
ribbon; thus by using similar ink in both, a continuous automatic renewing
of the ink of the ribbon may be accomplished, as the type taking ink from the
pad delivers such ink to the ribbon at the same place at which the ribbon
delivers ink to the paper and so the ribbon is continually and evenly inked,
whereby a highly distributed use or wear of the ink body is attained.
(5) By the joint use of the ink ribbon and the ink pads an advantage is also
obtained in that with the type moistened with ink the ribbon does not wear
out, but is kept always flexible, so that the frequent filling of the type with
fibrous material from the ribbon is avoided as well as the tiresome frequent
cleaning of the type.

page_text: In the accompanying drawings, the new auxiliary inking apparatus is repre-
sented in Figures 1 and 2 attached to a Yost type writing machine. Figures 3,
4 and 5 represent in section the two spools f and h upon which the inking
ribbon is wound and unwound and the mounting or insertion arrangement of
the one spool. Figure 6 finally shows the guiding piece for the ink ribbon i.
The ink ribbon i is guided over the two spools f and h arranged to left and
right on the frame m, which spools are simply mounted on small conical sleeves d
and p. The spool his fixed upon the conical sleeve on an axle o which is
mounted loosely revoluble in the eye or bearing g of a bracket arm n which is
fastened to the frame m so as to be easily removed. The spool has wound
upon it a complete inking ribbon about 12 to 15 metres in length. The ribbon
during the writing is wound from the right spool h on to the left spool f in such
a manner that by the intermittent or step by step movement of the carriage
during the writing the ribbon is shifted or wound to a small extent at each step.
Upon the bearing b for the axle c of the spool f a cord pulley g is loosely.
revolubly mounted, and in a recess in the side of said pulley, a watch spring t is
located which is fastened by one end to the bearing b of the spool axle c and
by the other end to the pulley g. The draw cord r fastened to the pulley g is
hung upon the same hook of the carriage to which the drawcord of the carriage
return spring of the machine is connected.
When the carriage is drawn towards the right, the cord r of the pulley is
wound off the pulley thus turning the latter and stretching the spring t within
the same, without the inking band being moved forward, during which move-
ment in order to hold the spool f firmly, a brake spring or a ratchet wheel and
pawl can be used.
Upon the forward (left) movement of the carriage during the writing, the
cord pulley g is turned back by said spring, the cord is again wound up and by
means of a spring pawl s which is fixed on the pulley and which engages in
a ratchet wheel e fixed to the axle c of the ribbon spool f, this ratchet wheel and
the axle c are rotated and therewith also the conical sleeve d which is fixed on
said axle and on which the spool f is placed in such manner that the spool is
rotated and the ribbon is wound up thereon.
As the diameter of the pulley is greater than that of the cores of the ribbon-
spools, the amount of the ribbon i which is wound up equals in length only a
small part of the length of the carriage movement, so that the ribbon i is well
utilised.
When the whole ribbon is wound from off the right spool h and on to the left
spool f, the spools f and h are simply exchanged left and right, and the ribbon i
moves anew through the machine.
The advantage of using a long ribbon which has to sustain no stretching
consists in that a great number of lines may be written without having to
reverse or change the ink ribbon and also that in place of a textile ribbon a
paper ribbon may be used, and instead of winding the same on a left hand spool
it may be moved forward by a pulley mounted on the bearing of the spool and
fitting on the axle c with a spring action.
C
A thin paper ribbon upon one side of which is laid an easily applied ink
medium permits of a much sharper impression than a textile ribbon. When
the paper ribbon, which will be found extremely cheap to produce, is used up,
it is simply thrown away and replaced by a new one.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
An interchangeable auxiliary inking apparatus for type writing machines
which can be used as well as or in place of the ordinary inking apparatus of a
typewriting machine, characterised by the inking ribbon which is guided over
the printing type being fastened with its ends on two spools which are moved

page_text: by a loosely mounted cord pulley, the cord of which is connected with the car-
riage of the machine in such a way that the backward movement of the carriage
only turns the said pulley and stretches a spring located in the pulley, whilst,
on the contrary, during the writing movement the pulley is rotated in a reverse
direction and a pawl carried by it engages in a ratchet wheel fastened upon the
axle of the winding up spool, so that this spool is only turned a little, that is to
say the inking ribbon is moved to an extent equal to only a part of that of the
carriage movement, in such manner that by the time the long ribbon has been
completely wound from one spool to the other, a great number of lines will have
been written, and moreover as the ribbon is not stretched, a paper ribbon can
be used in place of a textile ribbon, by which means sharper writing is obtained
substantially as herein before described.
