PROVISIONAL SPECIFICATION.
Improvements in Printing Telegraphs.
I, FREDERICK HERBERT WILLIAM HIGGINS, of 17 & 18 Cornhill, in the City of
London, Electrician, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object Improvements in Printing. Telegraphs.
There are now two well known types of telegraphic printers one in which the
printing is performed upon a paper tape and the other in which the printing is
executed in column. A series of machines of either type can be combined on one
circuit with a suitable transmitter and then all the machines on the circuit work
in unison.
Heretofore however the instruments have not been so constructed as to admit of
receivers of both types being worked together on the same circuit.
The column printing instrument which I employ is the single wire form of the
apparatus described in my Patent No. 2128 in the year 1887 in which the spacing
between lines is effected by a movement of the printing lever made at a time when
the type wheel is in a prearranged position. With this receiver I use its appropriate
transmitter.
The tape receiver to be worked on the same circuit is so constructed that the
type wheel is not traversed laterally with respect to the paper and in order that'
the spacing between lines in the column printer shall not interfere with the regularity
of the printing in the tape instrument means are provided for arresting the printing
lever when the paper is being shifted in the column machine; preferably I provide
in the latter a radial pin on the type axis facing the impression lever at the fresh line
position and abutting upon a stop piece on the printing lever in such a manner that
upon the occurrence of a fresh line in the column instrument, the printing lever in the
tape instrument is prevented from moving so that in the tape machine there will be
no spacing between the last letter printed on the end of the line and the next to be
printed at the beginning of the new line unless so determined by the operator pressing
the ordinary spacing key in addition to the fresh line key.

COMPLETE SPECIFICATION.
Improvements in Printing Telegraphs.
I, FREDERICK HERBERT WILLIAM HIGGINS, of 17 & 18 Cornhill in the City of
London, Electrician, 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 :—
This Invention has for its object Improvements in Printing Telegraphs.
There are now two well known types of telegraphic printers one in which the
printing is performed upon a paper tape and the other in which the printing is
executed in column. A series of machines of either type can be combined on one
circuit with a suitable transmitter and then all the machines on the circuit work
in unison.
Heretofore however the instruments have not been so constructed as to admit of
receivers of both types being worked together on the same circuit.
According to my Invention I combine in one circuit column printing instruments
and tape printing instruments to be worked by the same transmitter and I so arrange
that when the paper and type wheel in the column printer move to commence a new
[Price 8d.1

page_text: line the printing lever of the tape printing instrument is locked or rendered
inoperative so that no printing takes place and the paper is not moved.
The combined tape and column printing apparatus which I prefer are 1° The Single
Wire form of my column printing apparatus described in my Patent No. 2128 in the
year 1887 and the Single Wheel form of the printing receiving instrument described
in my Patent No. 668 of 1886 in combination with the Transmitting Apparatus
described in No. 12215 of 1884.
The column printing receiver and the transmitting apparatus are without modifica-
tion in this combination but the printing instrument described in Patent No. 668 of
1886 is altered in the manner shewn by the annexed drawings to admit of its working
correctly in the same circuit as a column printing receiver.
Figure 1 is a side elevation and Figure 2 an end elevation.
The type wheel axis A, carries a radial pin B bent at right angles at its end. This
pin when the blank space separating words is used is opposite a pin C projecting
from the printing lever E which allows the latter to move to advance the paper as
usual but without permitting the impression pad to touch the type wheel.
When the pin B is brought to a position shown by the dotted lines which precedes
its previously mentioned position by one tooth of the escapement the longer pin D
prevents the movement of the printing lever at the time when the spacing between
the lines is taking place in the column printing receiver.
A modification is shown in Figure 3. Here the pin D is replaced by a spring I
which the pin B on the type wheel axis touches as it comes round. The spring I and
the axis A are connected by wires F and G with the two ends of the printing
magnet H. Thus if a printing current comes to the magnet when B and I are in
contact it passes by the wires F and G in place of traversing the magnet coils and
the printing armature consequently is not attracted.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is-
:-
The combination on one circuit of a transmitter, one or more column printing
receiving instruments, and one or more tape printing receiving instruments: the latter
so arranged substantially as described that when the type wheel and paper of the
column printer move to commence a new line, the printing lever of the tape printing
receiving instrument is locked or rendered inoperative so that printing does not take
place and the paper is not moved..
