Belief That They Can Be
Sent Any Distance.
HAVE BEEN MADE
And T%elegraphers and Electricians
Are a Unit i n Saying That the
Machines Are a SucceSs--HOW the
Work is Done.

Cleveland, June ga series of long
distance experiments and exhibitions
have recently taken place over the wires
of the Western Union Telegraph com
pany, the last occurring within the past
few days between Cleveland and st.
Louis. when a number of w~ell-known peo-
pie of this city were present.
Among the pictures received during this
test were those of Rear Admiral Schley,
General Manager Melville f.. Stone, of
the Associated Press, and J. c. Barclay,
electrician of the western division of the
Western Union Telegraph
Telegraph electricians and others who
were present at this test are a unit in eX-
pressing their belief that the machines
viii do all that is claimed for them. 1t
may be added that printed or written
matter can be transmitted and reproduce
ed much more rapidly than pictures,
though only a few moments are consum-
ed in transmitting a cabinet size picture.
In transmitting a picture it is first
stereotyped on a flexible metal plate. The
outlines of he picture are exposed while
the remainder of the surface Of the plate
IS covered with a nOn~COnductive paint
The plate is then placed around a cylin-
der, and the machine. which is operated
by an electric motor, is started. The arm
cSoiAiS IL Tracer HAS us DdSG upon d
very finely threaded rod. and gradually
moves to the left until the entire picture
has been covered by the tracer. Both
sending and receiving machine are gov
erned by a simple synchronizing arrange
mont. so that both machines are regu-
lated in their speed automatically and
lnust run exactly together. The tracer at
the sending point controls the current on
the wire and closes the circuit whenever
1t 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,
however, is provided with a stylus con-
trolled by an ordinary telegraph sound
er. Around the cylinder is wrapped sew
elal sheets of paper, with carbon copying
sheets between them. The sounder-bear-
ing stylus closes dowr IN III" cylinder
and copying paper, recording the most
minute lines in the original picture as the
tracer at the sending point passes over
them.
In transmitting written or printed mat
ter the process is the same as above not
ed, eXcepS that the c0ry is either written
or copied on a flexible brass or metal
plate, the circuit being broken wherever
the tracer strikes the ink, which is nom
conductive. III this case the receiving in
strun ent is reversed. SO that it records or
the paper the opening instead of the clos
in = of the circuit. The synchronizing ar
rangement is the most ingenious II is
arranged SO that no matter how MANY
receiving machines there may be cut in
along the line it is not necessary to have
an operator or attendant to care for them.
The operator at the transmitting point
can easily correct or regulate the speed
of all.
1t is claimed that by using an enlarged
cylinder a half or even a full newspaper
page or matrice form can be placed in a
transmitting machine, operated. say in
New York or Chicago and reproduced
simultaneously in practically al of the
leading cities of the country within a
| very few minutes.
