page_text: PROVISIONAL SPECIFICATION left by. William Edward Newton at
the Office of the Commissioners of Patents, with his Petition, on
the 26th March 1872.-A communication from abroad by Georg
Schneider, of Vienna, in the Empire of Austria.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN TELEGRAPHIC
APPARATUS," to be as follows:-
い
The first part of this Invention relates to an arrangement of
mechanism whereby the ordinary Morse signals for telegraphic purposes
are cut or perforated through strips of paper, which are afterwards
placed in the telegraphic apparatus for transmitting the electric signals.
To this end the strips of blank paper to be operated upon are drawn
by a pair of nipping rollers at a regulated uniform speed over the face
of a stud fixed in the framework of the machine. Beneath this stud is
mounted a cutter wheel, which is driven by any suitable mechanism
and is carried on the end of a shaft mounted upon a pair of arms pro-
jecting from one side of a rocking shaft. Another arm projecting from
the opposite side of this rocking shaft carries the keeper of an electro-

page_text: magnet. When a current of electricity (of a longer or shorter duration)
is passed by means of a "Morse key" through the apparatus the keeper
will be drawn down and kept down for a corresponding length of
time, and the cutter wheel which is kept in constant rotation will be
forced up against the travelling strip of paper and will thereby cut a
perforation through it of more or less length according to the length
of time the keeper is drawn down.
The second part of the Invention relates to an arrangement of
telegraphic apparatus whereby the Morse signals thus perforated upon
the strips of paper can be transmitted to or received from a distant
station, and printed upon strips of paper in the usual manner, but with
much greater rapidity and accuracy than heretofore. This improved
transmitting instrument is based upon the principle of automatically
interrupting or breaking the current of electricity as it passes through
the instrument. This is effected by means of the perforated strip of
paper above mentioned, which being a non-conductor of electricity will
when interposed between any two points or parts of the instrument
arranged for the purpose stop the current of electricity, but when any
hole or perforation in the paper comes opposite these points metallic
contact will take place and the electric current will pass until again
interrupted by the interposition of the paper. If then one of the
perforated strips of paper above mentioned be drawn, or forced through
the transmitting instrument at an uniform speed, and in so doing be
made to pass under contact points arranged for the purpose, it will
be evident that when one of the perforations in the paper comes under
the contact points a signal of more or less duration will be made, and
as the Morse alphabet is composed of a combination of dots. . and
dashes which may be perforated in a strip of paper as aforesaid,
it follows that any combination of signals constituting a message can
be rapidly transmitted by merely passing the perforated strip of paper
through the machine, no particular skill on the part of the attendant
being required for the purpose.
