NEW INVENTIONS IN TELEGRAPHING.
A SPEED OF FROM EIGHT To FIFTEEN THOUSAND WORDS
ATTI


PER HOUR ATTAINED.
very valuable invention in telegraphng has
been perfected by DR.. Bradley, of New York, for
which, with other Inventions all tending to the still
further development of this great science, give
description, promising, however, that the first in
strument referred to is a partial infringement of
the Morse patent. Whether in view of the great
speed which has been attained in the transmission
of messages by means of this instrument it will be
accepted by the owners of the Morse patent
mains to be seen.
Bradley's improved telegraph apparatus embraces
all the elements of the Morse instrument, together
with ingenious and simple devices for transmitting
and recording with great rapidty by means Of type
and composing sticks, operators who read by sound
having nothing new to learn in practising their
usual mode with this new instrument. Messages,
when prepared for transmission, can be communi-
Gated and legbly recorded at the rate of from eight
to twelve thousand words per hour. On short
circuit fifteen thousand have been attained. From
one thousand to two thousand five hundred is good
work on either the Morse the printing instru
ments in use, which shows large gain in favor
of that of which we are writing.
The preparation OF the messages is performed by
setting them up in type, and when thus set the
types and composing sticks containing them are
passed through the instrument, where they meet
with such appliances as cause the opening and
closing of the circuit in such order as to produce
the record at the receiving office in the most regu-
lar and mechanically accurate manner. The record
is made sheets of paper with ink, in regular
manuscript.
The inventor has also conceived and constructed
a machine for making the type, by which he pro-
duces in finished state from five to ten thousand
in an hour, each type having teeth on one edge,
either short or broad, to represent the dots and
lines of the common telegraph letters, with the
Roman letters stamped on the 'front.' thus enabling
any one to set and distribute them, even should he
not be familiar with the telegraph letters. The
record is made with ink, in zgzag lines, producing
complete fac simile of the types as they are set
in the composing sticks.
DR.. Bradley proposes to furnish fonts of type at
cheap rates to business and famili's, who can
set up their dispatches, take them to the tee-
graph Office where they will be passed through the
instrument and recorded at the place of destination
in such clear and legible characters that any one
can read them after having given little attention
to the telegraph alphabet BY these means any
two correspondents will be able to communicate
with the greatest secrecy by simply changing the
denomination of the types and forming cipher of
their own 1t may be well to state that the record
ing instrument can be constructed with four cyin-
ders on which three copies be taken, stopping
only one at time, and changing the paper IN such
alternations that the transmitting apparatus need
