TRANSMIT SIGHT APPARATUS.
Telautophote Will Bring Distant
Points to View.

Points to View.
In ;redulous minds will probably be
exercised over an announcement OF
the invention of an instrument,
known as the telautophote, which is
apparently designed to bring all re-
mote parts of the earth into closer
touch by rendering distant and per-
haps now invisible objects to view.
The new mechanism. by electrical
aid. it is said. would cradle New
Yor'"er telephoning his wife in Chi
cago, to return home to study her
expressions during the conversation.

fight or q Denver convention some
day as visible from the Flatiron
Building as a Fifth Avenue stage.
present, however. the telauto-
photo will serve only as an attach
ment to the telephone, and its inyen-
tor. Mr.. Sidney Rothschild, Of No.
AT Eighth Avenue, New York, states
that in this connection 1t will give
complete satisfaction.
After two years of arduous work,
spending hours every night at work
on his invention, Mr.. Rothschild, who
is but twenty-siX years old, proved
his invention a theoretical success.
He sent it to Washington, where it
was approved and patented. and he
Is now working with models. to DEM
onstrate the practicability Of the de-
vice.
While DR.. Art. UT Korn. Of Mum
chen. succeeded by the transmission
OF a Photographic record. In convey
ing distant likeness to view, 1T
was not an instantaneous process like
that of the telautophote.
fr. Rothschild claims that his tel
ephone method Of transmission Is
much simpler than the negative post
ing method employed by DR.. korn.
It is founded upon the we'll known
truth that when selenium is struck
by fight It's electoral resistance
changes in relation to the amount of
light which shines upon 1t.
The instruments employed In the
sending and receipt Of the electrical
influence are of wonderfully simple
workmanship.
The transmitting consists of
selenium coated cell. upon which any
Image may be focused by camera
leEs through a transverse slot In
travelling steel belt. The belt
moves perpendicularly across the
face of the cell, which Is made up of
alternate copper and mica plates. In
sulated from each other. but con-
nected along the edges at one side
by a selenium coating. The inten-
sity of the light reflected upon the
cell will vary as the slot, travelling
across the cell, exposes the coating
to the lights and shades Of the i'm
age.
The main cell is controlled by what
Is called light control selenium cell,
moving in proportion so much faster
than the main cell that every point
on the surface of the main cell IS
covered. The controlling cell thus
trans. .orms every point of light into
an electrical impulse and sends 1t
by wire to a distant receiving sta
ton.
At the receiving rtation is a belt,
with perpendicular slots, rotating so
that pulley with horizontal slots
passing it causes points of light to
appear as one slot meets another. The
llsh+ comes from a vacuum tube with
il the belt, anG it varies In accord
wit the intensity o. the electrical
current from the sending station.

study Of electricity, building motors.
