I, CHARLES DENTON ABEL of No. 28 Southampton Buildings, Chancery Lane, in
the County of Middlesex, Consulting Engineer and Patent Agent do hereby declare
the nature of this invention to be as follows:-
"
In the Specification No. 7143 of 1885 I described a method and apparatus for
marking on the travelling paper strip of a Morse Inker" instead of the usual dots
and dashes, thin and thick transverse lines which occupy less length of paper than the
corresponding dots and dashes, and are more distinct to the eye, the thick line
representing the dash being very different in appearance from the thin line representing
the dot.
The present invention relates to a novel construction of apparatus for producing
such marks in a simple and efficient manner. For this purpose there is attached to
the arm of the armature lever which is worked by the electro magnet of the instrument
a small tube in which the ink or colouring liquid rises by capillary attraction from an
ink trough into which the lower end of the tube dips-on the top of the tube is mounted
a small roller having its axis transverse to the paper strip and on each side of the tube
are strips of leather or other suitable material by preference of a yielding nature which
bearing lightly against the underside of the roller serve to wipe from it superfluous
ink. Immediately above the tube, the paper strip is caused to pass round a guide
preferably of such a form as to present a very small surface of the paper to the ink
roller. As the paper strip travels past this guide the small ink roller below it is from
time to time moved up by the armature lever so as to bear against the under face of
the paper, and is thus caused to make a partial revolution at the same time marking on

page_text: the paper a line transverse to the paper strip which line has a height equal to the
length of the ink roller, and a breadth greater or less according as the armature lever
keeps the ink roller in contact with the paper for a greater or less time. When the time
of contact is very short, the mark made is a very thin line representing a dot, when the
time is greater, a thick line is produced representing a dash. The combinations and
successions of these thin and thick lines correspond with those of the dots and dashes
employed for the Morse or similar codes used in telegraphy. Instead of a capillary
tube, a wick may be used for feeding the roller. By the use of a disc or very narrow
roller, the ordinary dots and dashes may be made on the travelling strip of paper. A
capillary tube such as above described may be used for producing ink marks on the
paper strip without the intervention of a roller or disc.

page_text: I, CHARLES DENTON ABEL of No. 28 Southampton Buildings, Chancery Lane in
the County of Middlesex, Consulting Engineer and Patent Agent do hereby declare
the nature of this Invention and what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
In the Specification No. 7143 of 1885 1 described a method and apparatus for
marking on the travelling paper strip of a "Morse Inker" instead of the usual dots
and dashes, thin and thick transverse lines which occupy less length of paper than the
corresponding dofs and dashes, and are more distinct to the eye, the thick line
representing the dash being very different in appearance from the thin line representing
the dot. The present invention relates to a novel construction of apparatus for
producing such marks in a simple and efficient manner as I will describe referring to
the accompanying drawings. Fig. 1 represents a vertical soction, Fig. 2 a plan and
fig. 3 a part end view of a "Morse Inker" constructed according to this Invention.
To the arms of the armature lever s, worked by the electro magnet of the
instrument is attached a small tube b (shewn to an enlarged scale in transverse and
longitudinal section and in plan at Figs. 4, 5 and 6) extending down into a trough d
containing ink or other colouring liquid which rises in the tube by capillary attraction.
This tube is of rectangular form in section and has mounted on its top a small roller a
having its axis transverse to the paper strip, and on each side of the tube are strips c
of leather or other suitable material by preference of a yielding nature, which bearing
lightly against the under side of the roller serve to wipe from it superfluous ink.
Immediately above the tube and roller the strip of paper m is caused to pass round a
guide of such a form as to present a very small surface of the paper to the ink
roller a.
As the paper strip m travels past this guide, the small ink roller a below it
is from time to time moved up by the armature lever s so as to bear against the under
face of the paper and is thus caused to make a partial revolution at the same time
marking on the paper a line transverse to the paper strip which line has a height equal
to the length of the ink roller, and a breadth greater or less according as the armature
lever keeps the ink roller in contact with the paper for a greater or less time.
When the time of contact is very short the mark made is a very thin line representing
a dot, when the time is greater a thick line is produced representing a dash. The
combinations and successions of these thin and thick lines correspond with those of
the dots and dashes employed for the Morse or similar codes used in telegraphy.
The roller a may be supplied with ink by a wick instead of by a capillary tube.

page_text: The capillary tube may be used in connection with a disc or very narrow roller and
the ordinary dots and dashes may be made on the travelling strip of paper. Thick
and thin lines such as are described in the specification above referred to might be
made on a travelling strip of paper, by means of a capillary tube of rectangular section
without the intervention of a roller, but as in practice such tubes are apt to become
clogged at the top no claim is made to this arrangement.
Having now particularly described and ascertained the nature of the said Invention
and in what manner the same is to be performed I declare that what I claim is :-
In combination with the armature lever of Morse Inker apparatus a capillary tube
or wick dipping in an ink trough and surmounted by a marking roller, substantially
as and for the purpose herein set forth.
