Apparatus for Telegraphic
Purposes.
1, FRANK JACOB, of 12 Queen Anne's Gate, Westminster, in the County of
Middlesex, Electrical Engineer, do hereby declare the nature of this invention to
be as follows:-
:-
גי
In the Specification to Patent No. 9326 of 1886 granted to C. D. Abel was
described a construction of "
morse inker for marking the paper strip with thick
and thin transverse lines instead of dots, and dashes, wherein a marking roller of
very small diameter and of a length equal to that of the transverse lines to be
produced, was supplied with ink from the inking trough by a capillary tube or
wick and was brought against the paper strip by the armature lever on which it
was mounted.
According to my present invention, in place of supplying the said roller with
ink in the manner above described, I arrange it so as to rest on the periphery
of a disc whose breadth or thickness is about equal to the length of the roller,
and which is supplied with ink from the inking trough either by directly dipping
into the same, or, by preference, by coming in contact with a piece of felt or
other capillary or porous material dipping into the ink. The said inking disc has
its axis mounted on the armature lever and has a continuous rotary motion
imparted to it by the clockwork of the instrument, whereby it is made to convey
the ink to the marking roller and at the same time to cause this to revolve by
its frictional contact therewith. By this means the surface of the marking roller
is supplied very uniformly with ink and a freshly inked part thereof is always
presented to the paper strip, thus insuring the perfect marking of the latter.
The marking roller may either be carried by a spring arin fixed to the armature
lever or it may be carried by an arm pivotted to the casing of the instrument
and acted on by a spring so as to keep the marking roller in contact with the disc,
as it is moved up and down by the motion of the latter, or it may be arranged in any
other..suitable manner for carrying out the above purpose.

page_text: The capillary inking pad or surface may also be arranged in various ways, thus it
may he attached to an arm on the armature lever, or it may be carried by a fixed
spring that keeps it in contact with the inking disc.
The inking disc is by preference formed with a finely grooved periphery for
effectually taking up the ink and imparting it to the marking roller.

Improvements in "Morse Inker" Apparatus for Telegraphic
Purposes.
"I, FRANK JACOB of 12 Queen Anne's Gate Westminster in the County of
Middlesex, Electrical Engineer 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 :-
In the Specification to Patent No. 9326 of 1886 granted to C. D. Abel was
described a construction of "Morse Inker" for, marking the paper strip with thick
and thin transverse lines instead of dots and dashes, wherein a marking roller of very
small diameter and of a length equal to that of the transverse lines to be produced
was supplied with ink from the inking trough by a capillary tube or wick and was
brought against the paper strip by the armature lever on which it was mounted.
According to my present invention, instead of supplying the said roller with ink
in the manner above described; I arrange it so as to rest on the periphery of a disc
whose breadth or thickness is about equal to the length of the roller; and which is
supplied with ink from the inking trough, either by directly dipping into the same,
or by preference by coming in contact with a piece of felt or other capillary or
porous material dipping into the ink. The said inking disc has its axis mounted on
the armature lever and has a continuous rotary motion imparted to it by the clock-
work of the instrument; whereby it is made to convey the ink to the marking roller
and at the same time to cause this to revolve by its frictional contact therewith. By
this means the surface of the marking roller is supplied very uniformly with ink and
a freshly inked part thereof is always presented to the paper strip, thus ensuring the
perfect marking of the latter.
The marking roller may either be carried by a spring arm fixed to the armature
lever or it may be carried by an arm pivotted to the casing of the instrument and

page_text: acted on by a spring so as to keep the marking roller in contact with the disc, as it is
moved up and down by the motion of the latter; or it may be arranged in any other
suitable manner for carrying out the above purpose.
The capillary inking pad or surface may also be arranged in various ways, thus it
may be attached to an arm on the armature lever or it may be carried by a fixed
spring arm that keeps it in contact with the inking disc. The inking disc is by
preference formed with a finely grooved periphery for effectually taking up the ink
and imparting it to the marking roller.
The accompanying drawings illustrate two constructions of inking apparatus
according to my invention; one of these is shewn in Fig. 1 which is an clevation
and Fig. 2 which is a plan. The other, or modified construction, is shewn in
elevation by Fig. 3 and in plan by Fig. 4. In both sets of figures similar letters
are employed to indicate corresponding parts.
A is the inking trough containing
the ink or pigment in which is partly immersed the capillary or porous pad G.
This is pressed against the inking disc F, which is kept continuously revolving
during the action of the instrument, its axis being for that
to the clockwork. The periphery of the disc F is preferably grooved as shown,
purpose connected
the better to hold the pigment delivered to it by the pad G, which, in the one
construction shewn in Figs. 1 and 2, is stationary being pressed against the disc F
by an adjustable spring; in the other construction, shewn in Figs. 3 and 4, the
pad G is attached by an elastic arm to the armature lever B on which in
both constructions the disc F is mounted. E is the marking roller mounted on
an arm which in Figs. 1 and 2 works on a stationary pivot e and is urged by a
spring pressing the roller E on the periphery of the disc F.
In Figs. 3 and 4 the roller E is carried on an elastic arm from the armature
lever B. The strip of paper on which the marks are made travels round a pin
or roller of small diameter D, so that, when the armature lever B rises, the inked
roller Eis pressed against the bend of the paper making thereon a narrow mark
equivalent to a dot when the lover B is raised for a short time, and making a
broader mark equivalent to a dash when the lever B is raised for a longer time.
In Fig. the spring pressure on the pad G is adjusted by one of the screws
that hold the spring; in Fig. 3 the spring of the arms that carry the roller E
and the pad G is adjusted by turning more or less the pins from which they
project and fixing them by set screws.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is,
In telegraphic morse inker apparatus for making thin and thick marks in
substitution for the usual dots and dashes, the combination of the rotating disc F
mounted on the armature lover and the marking roller E arranged and operating
substantially as described.
