An Invention Which Promises tn Meas
urabIy RevOluti"nize Biography.
From the PhiladelOhia Record.
An invention that promises to measure
bly, revolutionize telegraphy has lately
been perfected in this city, and is now on
private exhibition at SO. 327 Walnut
street. In effect the new system is simply
an application of electricity to ype-writ-
ing, and the practical operation of the
invention is to instantaneously reproduce
at one end of a telegraph line letters
printed upon typewriter at the other
end. The most marvellous thing about
the contrivance is the fact that single
ordinary telegraphic wire conveys the
electric current and operates the receiv-
ing machine. In appearance the sending
machine is very much like an Or
binary typewriter. The instrument
shown yesterday had ~ beys-the letters
of the alphabet, the numerals and a few
punctuation marks. The receiving in
stfument was located in the same room,
and the visitor was enabled to see thar
upon the sheet Of paper held ~ it every
letter or ST struck by the sending ap-
pa aus Was instantly shown.
There was much to admire in the in
genius devices b, which the TWO machines
were made to beat as one. but it is not
alone as model Of fine workmanship that
tn invention surprised all who saw it.
The difficult thing for all to understand
was how single current gave the opera
tor absolute command over Ike which
formed more than forty characters, and
which might Just as well nave been
hundred miles away as in the same room.
The mystery was exclaimed by Mr.. H..
LinVille. who manipulated the machine.
Dropping technicalitjes and without go
ing INTO m mute details his explanation
amounted 10 til 8: Pressure upon any
key caused a certain number of magnetic
impu Ses t. pass through the line. The
number of these impulses fer tor each
letter, and they bring correspond ng let
tprs on the tYpe-wheel of the receiving in
strument into sucn position as to ISark
the impression on piece Of paper. Inc
machines worked admirably yesterday.
One of the gentlemen connected with the
new enterprise sa d:
"The distinctive advantages claimed
By this system 0ter all other telegrapuic,
telephone and type-WTlting instruments
are in its simple and inexpensive con-
stTuctiOn and the ease OF operating il.
Any person who can read can transmit
and receive messages through it as cor
recily as could the most experienced *.
pert using the Morse instrument. IL II as
rapid as 1t is accurate, and all messages
by it being autOm aticaly printed, boih at
the point of transmission and that of re-
ceptiOn, they can be received with safety
and reliability in the absence as. we'll as
in the presence Of the recipient. The re-
cording OF messages at both points pre-
cludes all questions of errors in transmits
sion. II cannot be read by sound. and is
consequently the only method for pre-
serving privacy in electrical communica-
cation. 1t is at once a stock indicator,
telephone and type-writing telegraph"
The inventor was MIR. G. orge NJ. Hath
away, but Mr.. Linville has done much to
make the cOntrlvance practical.
