tons.
At the very beginning il upset what has
always been considered a law of physics.
1t has always been thought that when
a piece OF metal was magnetized the en-
tire structure became a polarized Hlasne-.
Herr Poulsen discovered and demonstrat-
ed the fact that steel wire viii receive
impressions by means of an electro mag
net in minute portions OF its composition.
establishing a permanent record that may
be reproduced at any time.
Probably the widest and earliest use
to which the telegraphone viii be put
in the business world is in the direction Of
correspondence. The business man may
dictate his letters into the transmitter
at his desk according to his conyen-
ience-quickly and continuously or at
odd times as his duties interrupt his
work. When he desires to correct errors
or alter words or sentences he can do 50
by simply touching a switch and erasing-
any portion of the record and making
any alteration he chooses. This is impos-
sibie when using the phonograph His
typewriter may sit in another room and
write the letters. which the telegr2phoRe
will repeat to her rapidly or slowly or in
portions as she may desire. the speed be-
ing entirely under her control
This form of the machine will be hailed
with joy by the wives of business men,
who have long felt thhe need OF some
machine that would widen the space
between the chairs of the boss" and
the typewriter with peachblow complex
ion and sun-kissed hair
A more detailed description of the work
ings of the teIegraphone is as follows:
The apparatus consists OF a drum Of
brass about III inches in length by 5Is
inches in diameter. On this drum (which
can be turned by motor, by o'clock
work or by hand is wound 90 turns of
steel piano wire A tiny magnet, mounted
on a SHAFT, travels from right to left
across the drum in contract with the
wire. When the magnet reaches the end
OF the drum it can be almost instantly
run back to the beginning side again.
This recording electromagnetic is con-
nected with an ordinary telephone trans
mitted.
When the transmitter is spoken into
it acts as a tap upon the battery and
causes currents of varying strength to
pass through the wire wound on the
drum electro-ma gnet AS the steel wire
wound on the drum passes in front of
the magnet varying magnetic field mag
DetiZes transversely the steel wire and
the Lines of force are permanently re-
corded therein.
After the steel spiral has been filled,
making a record of from one hundred to
oneh undred and twenty words, the tiny
magnet is returned to the point where
the record first started and a receiving
telephone is attached. The cylinder
again revolves. and as the magnetized
steel wire passes before the poles of the
electro-ma gnet is forms a species of mag
neto-electric generator. giving out ccur-
rents of electricity of strength and di-
rection corresponding to the magnetiza-
ton of the steel wire. which correspond
ingly affect the receiving telephone, and
reproduce the sounds and words original
ly spoken with absolute fidelity.
Here are some principal commercial
uses to WHICH it is proposed to apply
the telegraphone:
Dictation machine for letters and docu-
fnent work.
Musical records similar to those of
the photograph.
Stock and market news distribution.
Newspaper news distribution.
Telephone connection for recording teIe-
phone messages in the absence of the
subscriber.
Telephone relay for repeating telephone
messages from one point to another, so
that telephone communication can be
had over distances hitherto impossible.
Railroad telegraphone for despatching
trains.
II the telegraphone succeeds in acting
as a satisfactory telephonicc repeater, or
relay. IL will enable us to carry on con-
versations by phone between New York
and San Francisco and other points out
side of the present range of the instru-
ment
Some time ago one of the telephone
companies publicly offered reward Of
100000 for thoroughly satisfactory
telephone repeater.
The leading scientists and electricians
regard Herr Poulson's invention as
marvel both in the way of ingenuity and
as a commercial proposition.
SO the day may not be very far away
when the mails will be full OF the little
discs bearing messages OF business. af-
lection, secrecy and friendly gossip Mag !
netism may develop into a power as far !
superior to electricity as that lively ener-
gy is 10 steam.
