Pictures By Wire.

Cleveland, O., June 24.-A series of
long distance experiments and exbi-
billions of the electric photographing
process have recently taken place over
the wires of the Western Union Tele-
graph Company, the last occurring
within the past few days between
Cleveland and St Louis, when a num-
ber of well known people of this city
were present.
Among the pictures received during
the test were those OF Rear Admiral
Schley, General Manager Melville E.
Stone, OF the Associated Press, and j.
e. Barclay, electrician of the Western
Division of the Western Union Tele-
graph Company,
Telegraph electricians and others
who were present at this test are a
unit In expressing their belief that the
machines will do all that is claimed
for them 1t may be added that print
ed or written matter can be transmit
ted and reproduced much more rapid
ly than pictures, thouhg only few
moents are consumed in transmit, ing
cabinet size picture.
In transmitting picture 1t is first
stereotyped on flexible metal plate.
The outlines of the picture are exposed
while the remainder of the surface of
the plate is covered with a noncon-
ductive paint. The plate is then placed
around cylinder, and the machine
which is operated by an electric motor,
is started. The arm bearing the
tracer has its base upon very finely
threaded rod, and gradually moves to
the left until the entire picutre has
been covered by the tracer
Both sending and receiving ma
hines are governed by simple syn
chronizing arrangement, so that both
machines are regulated in their speed
automatically and must run exactly
together. The tracer at the sending
point controls the current on the wire
and closes the circuit whenever it
comes in contact with the exposed
lines of the picture.
At the receiving end the apparatus
is similar to that at the transmitting
point; the projecting arm over the
cylinder, hiwever, is provided with
stylus controlled by an ordinary tele-
graph sounder. Around the cylinder
are wrapped several sheets of paper,
with carbon copying sheets between
them
The sounder bearing the stylus
closes down on the cylinder and copy
ing paper, recording the most minute
lines in the original picture as the
tracer at he sending point passes over
them. In transmitting written or
printed matter the process is the same
as above mentioned, except that the
copy is either written or copied on a
flexible brass or metal plate, the cir
cult being broken whenever the tracer
strikes the ink, which is nonconduc-
tive. In this case the receiving is re-
versed, so that it records on the paper
the opening instead of the closing of
,-.e circuit. The synchronizing ar
rangement is most ingenious, and is
arranged so that, no matter how
many receiving machines there may
be cut in along the line it is not neces-
sary to have an operator or attendant
to care for them. The operator at the
poin can easily correct
or regulate the speed OF all.
1t is claimed that by using an en-
larged cylinder a half or even full
newspaper page or matrice form can
be placed in transmitting machine,
operated, say in New York or Chicago,
and all produced simultaneously in
practically all of the leading cities OF
the country within a very few minutes.
