I, OTTO ROMANZE of 109 Farringdon Road in the County of Middlesex, Telegraph
Instrument Maker do hereby declare the nature of my Invention to be as follows:-
The object of my Invention is to provide a simple and efficient apparatus for electrio
type printing. The transmitting and receiving instruments are according to my
Invention so relatively arranged as to ensure the correct printing of the messages by
providing arrangements by which the true working or movement of the apparatus and
correct printing are insured.
The transmitting instrument consists of a circular series of make and break contacts
by contact with which during rotation an arm operated by any suitable motor
constantly breaks and completes a circuit so as to transmit to the receiving instrument
electrical impulses due to the making and breaking of the contact by the arm. The
axis of this arm is provided with an escapement wheel regulated by a pallet to act as
a regulator to ensure the proper make and break of the arm and the true position over
the insulated and conducting portions of the circular track when a letter or sign is
being printed as hereinafter described. The electrical impulses for operating the
printing devices are transmitted from the transmitting instrument by incans of contact
mmakers or keys of the ordinary kind so situated that their operation will cause the
rotating arm to be arrested. The receiving instrument has two electro magnets or
solenoids the armature or core of the one actuating by means of an arrangement of
double pawls a ratchet wheel fixed on an axis upon which is carried a wheel or disc on
the side of which. are formed or fixed the types from which the printing is effected.
The said pawls are so arranged that the ratchet wheel is moved to the extent of one
tooth by the forward movement of the aforesaid armature or core of what I will call
the first coil and to a similar extent by the backward movement of the said armature
or core which may be effected by a spring. The movements of the type are by the
arrangement of the transmitting and receiving instruments as described governed so
as to be perfectly synchronous and bring with certainty at each movement a type in
proper position for printing.
The axis of the type wheel is encircled by an electro magnet or coil so that the said
axis constitutes the armature or core of the said magnet or coil which I will call the

page_text: second coil. The first coil has the circuit from the circular track of the transmitter
passed round it and the second coil has the circuit from the keys of the transmitter
passed round it. In proximity to the type wheel are guides for the strip upon which
the printing of the message is effected the said strip being passed over a plate with
an opening in it which only admits of the printing of the one type which is opposite
the opening when the printing movement is given to the printing wheel. The strip is
moved along the width for one type at each printing movement of the type wheel by
means of a pawl carried by the type wheel or its axis operating a ratchet wheel on
the axis of the feed roller of the strip.
When the machine is in operation the travel of the arm over the circular track of
the transmitting instrument sends electrical impulses around the first magnet coil and
so the type wheel is moved round the width of a type for each make and break the
escapenient wheel and pallet ensuring true movement. When a key is operated to
print a type the revolving arm is stopped thereby over either an insulated or a
conducting portion of the track and the rotation of the type wheel is discontinued
and the current passing round the second coil caused the type wheel to move length-
wise to its axis to print upon the portion of the strip presented to it by the movement
of the feed roller as before described. The type wheel I prefer to arrange horizontally
and to sustain a part of its weight by a spring arrangement.

Instrument Maker 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:-
The object of my Invention is to provide a simple and efficient apparatus for electric
type printing The transmitting and receiving instruments are according to my
Invention so relatively arranged as to insure the correct printing of the messages by
providing arrangements by which the true working or movement of the apparatus and
correct printing are insured I will describe my Invention with reference to the
accompanying drawings whereon Figure 1 is a plan of the transmitting instrument
Figure 2 is a vertical section of the same Figure 3 is a plan of underside of the same
and Figures 4 and 5 are enlarged details of parts of the same as hereinafter described
Figures 6 and 7 are respectively a plan of top side and an elevation of the receiving
instrument-Figure 8 is a plan of underside of the same Figures 9. 10. 11 and 12 are
enlarged details of a device for ensuring the true relative working of the transmitting
and receiving instruments Figures 13 and 14 are respectively an elevation and a plan
of the mechanism for actuating the type wheel of the receiving instrument step by
step to present each letter or sign successively over the place where printing is effected
and Figures 15 16 and 17 are enlarged details of the mechanism for giving the proper
feed to the strip upon which the message is printed Figure 18 is a diagram of the
circuits as hereinafter explained.
The transmitting instrument consists of a circular series of make and break contact
pieces a a projecting from the central plate A by contact with which pieces during
rotation an arm B operated by any suitable motor constantly breaks and completes a
circuit so as to transmit to the receiving instrument electrical impulses due to the
making and breaking of the contact by the arm-The axis of this arm may be provided
with an escapement wheel regulated by a pallet to act as a regulator to ensure the
proper make and break of the arm and the true position over the insulated and
conducting portions of the circular track when a letter or sign is being printed as
hereinafter discribed.
The plate A is mounted upon a disc C of wood or other suitable material and is
supported by pillars c from the base C² the space between the disc C and the base C
ccommodating the notor of the arm B which is shewn as consisting of a spring
barrel D transmitting motion through the train of wheels or clockwork dd to the
axis of the arm.B-The motor' may be provided with the ordinary flyer for
controlling the motion of the gear as in ordinary clockwork.
The arm B is provided with a spring contact piece 62 and it is connected to the line
eading to the receiving instrument there being a battery in any suitable position on
he line so that as the arm B revolves and makes and breaks contact as it passes over
he pieces a electrical impulses are set along the line wire and around Electro
agnets E on the receiving instrument to operate the type wheel F of that instrument

page_text: letter by letter or sign by sign as the arm B alternately makes and breaks contact
at a a the movement of the type wheel being such that as the arm B, passes by a
letter or sign on the circular series of keys G of the transmitting instrument a circular
letter or sign on the type wheel of the receiving instrument is brought into position
to print. Electrical impulses for operating the printing wheel to print the letter or
sign so presented are transmitted from the transmitting instrument by means of the
contact makers or keys G which may be of the ordinary kind and they are so situated
that their operation will cause the rotating arm B to be arrested for, and during
printing. This is effected by means of a second arm El fixed to the axis band
revolving with it. This arm H is in the path of the stems of the keys G when
depressed so that the said arm H is arrested by the stem of whichever of the keys is
depressed.
This will be clearly understood from Figures 4 and 5, Figure 4 shewing a key in
its normal position when no printing motion is being transmitted to the receiver
whilst Figure 5 shews a key depressed and arresting the arm H. I is a sliding
insulated stop which can be moved inwards to arrest the arm H to stop the motion of
the revolving arms Band H. Each stem of the keys G when depressed makes
Electriccontact with the arm H so that an Electric impulse is sent along the line 13
Fig. 18 and around Electro magnets K on the receiving instrument to effect the
printing as hereinafter described.
เ
gare springs, for returning the keys to their normal position. The Electro-magnet
or solenoid or set of Electro magnets or solenoids, E, has an armature, f, (or core,) for
actuating the type-wheel to move it in unison with the arms B and H of the trans-
mitting mechanism. This is effected by means of an arrangement of double pawls /
and ratchet wheel 2 fixed on an axis upon which is carried the wheel or disc F on the
side of which are formed or fixed the types from which the printing is effected. The
types may be engraved or otherwise formed or fixed to the wheel or disc for instance
they may be india rubber types such as are used with ordinary india rubber stamps.
The pawls are so arranged that the ratchet wheel is moved to the extent of one
half tooth by the forward movement of the aforesaid armature f (or core) of what I
will call the "first coil" and to a similar extent by the backward movement of the
said armature or core which may be effected by a spring as at 13. The movements of
the type wheel are by the arrangement of the transmitting and receiving instruments
as described governed so as to be perfectly synchronous with the movement and
making and breaking of contact by the arm B so as to bring with certainty at each
movement a type in proper position for printing. On the same axis as that on which
the type wheel F and ratchet wheel are fixed is a detent wheel the detents *
which engage therewith being carried by the opposite arms of the pawls (sec
figures 13 and 14). The axis n of the type wheel F passes through a collar or
sleeve n² which is encircled by an electro magnet or coil or passes between the coils of
a set of coils (K) so that the said axis can be pulled down by a current passing through
the coils and attracting the armaturen of the said magnet or coil (which I will call the
"second coil") the said armature being fixed to the said sleeve ². It will be understood
that the axis of the type wheel revolves in the sleeve. In proximity to the type wheel F
are guides p for the strip q upon which the printing of the message is effected,
the said strip being passed over a plate which is only of a width admitting
of the printing of the one type which is opposite thereto when the printing
movement is given to the printing wheel F. The strip q is moved along
the width for one type at each return motion after the printing movement of
the type wheel by means of a pawls Fig. 16 carried by the type wheel or the
sleeve and operating a ratchet wheel t on the axis t2 on which is a toothed wheel t³
gearing with another wheel on the axis of the feed roller u of the strip q. When
the machine is in operation the travel of the arm B over the circular track of the
transmitting instrument sends electrical impulses around the first magnet coils E and
so the type wheel F is moved round the width of a type for each make and for each
break, the escapement wheel and pallet when used insuring true movement.
key is operated to print a type the revolving arm H is stopped thereby over either an
When a

page_text: insulated or a conducting portion (a) of the track and the rotations of the arms of the
transmitter and of the type wheel of the receiver are discontinued and the current
passing round the second coils K causes the type wheel to move lengthwise to its axis
to print upon the portion of the strip 7 presented to it by the movement of the feed
roller u as before described. The type wheel F I prefer to arrange horizontally and
to sustain a part of its weight by a spring n' which returns the type wheel F to its
normal position. In order to insure the proper starting of the instrument it is
preferred to use therewith a snail or spiral groove on the type wheel with a stop
at the length of the groove being such that the type wheel can revolve completely a
certain number of times (say twice) and then the stop 2 will come against the pin w
on the arm which pin engages (when the type wheel is not depressed) in the said
groove as shown in Figure 9.
When the type wheel F is depressed the pin will be clear of the groove as shewn
in Figure 12 and the spring we will tend to bring the said pin w into such a position
that it is in the starting point or inner most part of the groove. The inner part of the
snail groove is in direct line with this starting point and the zero mark on the type
wheel F is over the printing plate when the pin is in this starting part of the
groove so that if when commencing a message the zero key of the transmitier be
depressed the depressing of the type wheel resulting therefrom will cause the pin w to
be brought by its spring always into the starting point of the groove and thus the
transmitting and receiving instruments will work synchronously as the printing
wheel will then have the zero mark over the printing plate. I have shewn in
diagram at Figure 18 the courses of the currents by which the shifting of the type
wheel and the printing action are obtained. X is the battery having one pole
connected to earth by the wire 1 the other pole leading by the wire 2 to the binding
screw 3 and thence by the wire 4 to the inner end of the arm B and thence when the
outer end of the arm makes contact with the projections a by the wire 5 to the
binding screw and by the wire 7 to the binding screw 8 of the receiving instrument
thence through the coils E which cause the intermittent rotation and shifting type by
type of the type wheel and thence to earth by the binding screw 9 and wire 10.
This current is shown by the full lines. The other circuit in so far as it does not
form part also of the first circuit is shown by the dotted lines. It passes from the
battery X by the wires 2 and arm B and through the other arm H (when it makes
contact with the one of the stems of the keys G which is depressed) and thence
passes by the plate J, connects the key stems electrically and by the wire 11. binding
screws 12 and by the wire 13 binding screw 14 and wire 15 to the coils K which
cause the movement of the printing wheel to print and thence by the wire 16 binding
screw 9 and wire 10 to earth.
