Year: 1873

page_text: LETTERS PATENT to Geminiano Zanni, of Compton Road, Highbury,
in the County of Middlesex, Gentleman, for the Invention of
"IMPROVEMENTS IN MAGNETO-ELECTRIC MORSE INK PRINTING TELEGRAPHIC
APPARATUS."
PROVISIONAL SPECIFICATION left by the said Geminiano Zanni at the
Office of the Commissioners of Patents, with his Petition, on the
30th June 1873.
I, GEMINIANO ZANNI, of Compton Road, Highbury, in the County of
Middlesex, Gentleman, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN MAGNETO-ELECTRIC MORSE INK PRINTING
TELEGRAPHIC APPARATUS," to be as follows:-
This Invention has for its object improvements in magneto-electric
Morse ink printing telegraphic apparatus arranged in accordance with
"Zanni's system," having inking apparatus applied thereto. For this
purpose a compound magnet is arranged with a revolving armature, the

page_text: f
speed of which is regulated according to my Invention by means of a
governor, which is actuated by means of a toothed wheel and pinion, or
a compensating rotating fly may be substituted for the governor.
I will now describe. the apparatus for printing a continuous strip of
paper in accordance with my improvements.
The armature receives motion in the following manner :-A pinion on
the axis of the armature takes into a wheel on the lower end of a short
axis supported by a bracket. The pinion on the short axis takes into a
toothed wheel on another axis, the upper end of which carries a pinion,
which takes into a toothed wheel on a spring or clockwork barrel, which
by means of bevil pinions is connected with a winding-up handle for
giving motion through the train of wheels previously described to the
armature, as is well understood. By pushing in a sliding rod the clock-
work mechanism is stopped, and by drawing it out it is started; a rod is
arranged for opening the keeper in sending or receiving a message.
The printing mechanism consists of an electro-magnet, an armaturo
lever, which carries a pressing roller or bar to press the strip of paper
up against an inking disc, to which the ink is conducted by an endless
chain from an ink reservoir or vessel, adjusting screws being arranged to
control the movement of the armature lever. The strip of paper is fed
forward, and the inking apparatus is actuated in the following manner :—
The paper
ris conducted from a reel under a roller, thence over a pressing
roller or bar, and between feed rollers. A pinion on an axis drives a
toothed wheel on a spring barrel. A pinion on the first named axis takes
into and drives a toothed wheel upon another axis, upon which is fixed
the toothed wheel, which takes into and drives a toothed wheel on the
axis of one of the feed rollers. The toothed wheel last referred to takes
into and drives a toothed wheel fixed on the axis of the inking disc.
Another toothed wheel takes into and drives a pinion on the axis of an
endless chain wheel so as to raise the ink from a vessel containing ink
and transfer it to. the inking disc in accordance with my Invention.
According to another arrangement of inking apparatus for printing
telegraphic messages in accordance with my Invention the ink is con-
tained in a revolving perforated cylinder, which is covered with cloth or
felt, and the ink is transferred to a revolving pen or marker, which
consists of two concave discs forming a chamber for holding a small
quantity of ink at the point, where it acts to print marks on the paper

page_text: when the paper is pressed against it by the armature lever. Motion is
communicated to the parts in like manner to that previously described.
In another arrangement of inking apparatus the ink is transmitted
from the ink reservoir by a disc (which rotates therein) to the disc,
against which the paper is pressed to be printed in accordance with my
Invention by the action of the armature lever from time to time as
required.
In another arrangement the ink is raised from the ink reservoir by
means of an endless band or chain and transmitted dircct to the paper to
be printed according to my Invention by being pressed against it from
time to time by the armature lever.
.

cause the same to be filed in the Great Scal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Geminiano Zanni, do hereby declare
'the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention has for its object improvements in magneto-electric
Morse ink printing telegraphic apparatus arranged in accordance with
"Zanni's system," having inking apparatus applied thereto.
Figure 1 of the Drawings hereunto annexed shows a vertical section
of magneto-electric apparatus arranged with inking and printing
mechanism arranged in accordance with my Invention, and Figure 2 is
a horizontal section of the same.
As the nature of magneto-electric apparatus of this description is well
understood, it will not be necessary for me to give a minute description
thereof, except so far as relates to my present improvements. a is a
compound magnet arranged with a revolving armaturo b, the speed of
which is regulated according to my Invention by means of a governor c,
which is actuated by means of the toothed wheel and pinion c¹, as
shown in the Drawings, or a compensating rotating fly may be substituted
.for the governor c.
I will now describe the apparatus for printing a continuous strip of
paper in accordance with my improvements.
The armature receives motion in the following manner:-A pinion
d on the axis of the armature takes into and drives the wheel e on the
. lower end of the short axis e¹ supported by the bracket e². The pinion
es on the short axis e¹ takes into the toothed wheel on the axis f¹, the
upper end of which carries the pinion f³, which takes into the toothed
wheel g on the spring or clockwork barrel, which, by means of the bevil
pinions and ¹ is connected with the winding up handle h² for giving
motion through the train of wheels previously described to the arma-
ture b, as is well understood. By pushing in the sliding rod i the clock-
work mechanism is stopped, and by drawing it out it is started, a rod is
arranged for opening the keeper in sending or receiving a message.

page_text: The printing mechanism shown in Figure 1 consists of an electro-
magnet m, an armature lever m³, which carries the pressing roller or
bar m² to press the strip of paper up against the inking disc m³, to which
the ink is conducted by the endless chain m* from the ink reservoir or
vessel m; m³, mo, are adjusting screws arranged to control the movement
of the armature lever m². The strip of paper is fed forward, and the
inking apparatus is actuated in the following manner :-n is a reel, from
which the paper is conducted under the roller n', thence upwards over
the pressing roller or bar m², and between the feed rollers n³, n³, as shown.
o is a pinion on the axis p, which is driven by the toothed wheel g on
the spring barrel. The pinion p¹ on the axis p takes into and drives
the toothed wheel q¹ upon the axis q, upon which is fixed the toothed
wheel q², which takes into and drives the toothed wheel 2* on the axis of
one of the feed rollers n³. The toothed wheel n' takes into and drives
the toothed wheel m* fixed on the axis of the inking disc m³, and the
toothed wheel m* takes into and drives a pinion on the axis of the endless
chain wheel m³, so as to raise the ink from the vessel m³ containing ink
and transfer it to the inking disc m³ in accordance with my Invention.
Figure 3 shows another arrangement of inking apparatus for printing
telegraphic messages in accordance with my Invention, the parts which
correspond to those previously described being marked with similar
letters of reference. In this arrangement the ink is contained in tho
revolving perforated cylinder », which is covered with cloth or felt, and
the ink is transferred to the revolving disc or marker s, which acts to
print marks on the paper when the paper is pressed against it by the
armature lever m², motion being communicated to the parts as previously
-described and shown by the train of wheels.
Figure 3 shows a revolving pen or marker s, which consists of two
concave discs forming a chamber for holding a small quantity of ink at
the point where it acts to print marks on the paper when the paper is
pressed against it by the armature lever m², thus dispensing with the
cylinder in the arrangement previously described.
In the arrangement of inking apparatus shown at Figure 4 the ink is
transmitted from the ink reservoir by the disc (which rotates therein)
to the disc 8, against which the paper is pressed to be printed, in accord-
ance with my Invention, by the action of the armature lever m¹ from
time to time as required. .

page_text: In the arrangement shown at Figure 5 the ink is raised from the ink
reservoir by means of an endless band or chain m, and transmitted
direct to the paper to be printed, according to my Invention, by being
pressed against it from time to time by the armature lever m', as clearly
shown in the Drawings.
In the arrangement shown at Figure 6 the ink is contained in a small
inverted bottle m³ secured by a felt stopper, which allows the ink to flow
gradually on to the revolving printing disc 8, against which the strip of
paper is pressed as required to be printed, as previously described.
Figure 7 shows an arrangement of inking apparatus similar to that
shown at Figure 4, the inking disc s in this arrangement being carried
by the armature m³, the inking discs being supplied with ink either
from the disc or direct from the ink reservoir m³, the disc in that
case being dispensed with; the strip of paper in this case is introduced
and delivered in the same direction as shown, being driven by similar
mechanism to that previously described.
Having thus described the nature of my Invention, and the manner
of performing or carrying the same into practice, I would have' it
understood that I do not intend to confine myself to the exact details
hercin-before described so long as the broad principle of my Invention
is retained, but what I claim is, the application of inking and printing
apparatus to magneto-electric telegraphic apparatus, substantially in the
manner herein-before described and shown in the Drawings hereunto
annexed.
In witness whereof, I, the said Geminiano Zanni, have hereunto set
my hand and scal, this Twenty-ninth day of December, in
the year of our Lord One thousand eight hundred and seventy-
