tire four inches wide. Two sprocket
chains run horizontally while third
operates perpendicularly, running over

the front wheel, and a four-inch
srrocket, fastening to shaft directly
over it. The machine weighs $50

dnce the weight to about $50 pounds.
A French periodical describes tel
escrptor," recently constructed by the
Societe Industrielle des Telephones.
The machine is a typewriter furnished
with electric contacts under each key,
that instantaneous currents may be
sent into a line when each is depressed.
A pOlarized electro-magnet Is actuated
by these currents controlling the es-
capement of a clockwork arrangement.
On the axis of this clockwork a brush
sweeps over a fixed current distributor,
with tWenty-eight contracts and a
type wheel, on whose circumference
letters and signals are engraved in re-
lief. On a movable drum In front
Of the type wheel passes a paper band
for receiving an impression. When
two people possess a telescriptor, the
calling operator presses down two
levers. the other operator only one.

both under the eyes of the operator
and receiver of the message. At the
end Of the communication, signal is
given, the first operator raises his sec
ond lever, while the other depresses
his and the receiving instrument has
become a transmitter, and the trans
hitting machine a receiver. The de-
vice can be worked as telegraph If

about 100 words per minute. When
necessary to send orders involving
precise terms, and in many branches
of indu try the telescriptor is said to
surpass the telephone in usefulness.
