Mr. F. C. Creed, of
—308—
The system has been in steady commercial use for
about three years between London and Edinburgh, and
a circuit is now being equipped with Murray apparatus
between London and Dublin. For about eighteen months
it has been working between Hamburg and Berlin.
An installation has been set up between St. Petersburg
and Moscow. An installation of the apparatus for
Calcutta-Bombay (1,200 miles) is now approaching com-
pletion and arrangements are being made for a staff of
Murray experts to go out to India to instal the system.
A set is nearly finished for working between Vienna and
Prague, and arrangements are also being made for
manufacturing Murray apparatus to equip several other
circuits.
It may be mentioned that Mr. Murray has been engaged
by the British Post Office for a term of years to invent and
develop some new printing telegraphs to suit special con-
ditions. Mr. Murray points out that this engagement
is in accordance with a tendency that has become very
marked of recent years.
Creed’s Telegraphic System.
Lenzie, in Scotland, has also invented, and is now perfecting
a series of three machines having similar objects, and
from an account of the system in a Glasgow paper we learn
that, although other inventors have produced instruments
which aim at results somewhat similar to those achieved
by Mr. Creed’s Perforator, Receiver and Printer, yet they
labour under this disadvantage, that they deal with a
perforating alphabet entirely different from the Morse
which is used in the Telegraph service of the United
Kingdom. Mr. Creed has endeavoured to adapt his
machines to the Morse alphabet, and has succeeded in
doing so. . j j •
After many years of labour, Mr. Creed succeeded in
producing the perforator, which is now being tested in
London. It is operated by means of an ordinary type-
writer keyboard. When the lettered keys are touched
they perforate a corresponding Morse letter on the paper
tape. The speed with which this is accomplished is about
the same as that attained in ordinary typewriting, and
as this is double the average speed of ordinary punching,
the new perforator can perform the work of two punchers.
The tape perforated after the new fashion may be put
into the Wheatstone transmitter at the London end of
the wire and received at the other end in the manner at
