Year: 1865

page_text: LETTERS PATENT to Louis John Crossley, of Halifax, in the County of
York, Carpet Manufacturer, for the Invention of "IMPROVEMENTS IN
ELECTRIC TELEGRAPHIC APPARATUS."-A communication from abroad by
Louis Brequet, of Paris, France.
Sealed the 2nd February 1866, and dated the 7th August 1865.
PROVISIONAL SPECIFICATION left by the said Louis John Crossley at
the Office of the Commissioners of Patents, with his Petition, on the 7th
August 1865.
I, LOUIS JOHN CROSSLEY, of Halifax, in the County of York, Carpet Manu-
facturer, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN ELECTRIC TELEGRAPHIC APPARATUS," a communication to me from abroad by
Louis Brequet, of Paris, France, to be as follows:-
This Invention consists in combining in one instrument the bell, the receiver,
and the transmitter parts of electric telegraphic apparatus, and in constructing
and arranging those parts so that when the bell is placed in circuit any current
traversing the line will ring it, and when the bell is thrown out of circuit the
receiver will be placed in circuit, and also in position for the clerk to receive
the message. The apparatus is in two parts, hinged together in the form of a
box or folding case; the bell is fixed outside upon the lid or top part, the
receiver within the same part, and the transmitter in the bottom part. When

page_text: the apparatus is closed the bell is in circuit, but when open is thrown out and
the receiver is placed in circuit. The transmitter is also placed in circuit
when the apparatus is in this position.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Louis John Crossley in the Great Seal Patent Office on the
7th February 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Louis
JOHN CROSSLEY, of Halifax, in the County of York, Carpet Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of August, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Louis John Crossley, Her special licence that I, the said Louis John
Crossley; my executors, administrators, and assigns, or such others as I, the said
Louis John Crossley, my executors, administrators, and assigns, should at any
tine agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
ELECTRIC TELEGRAPHIC APPARATUS," a communication to me from abroad by Louis
Brequet, of Paris, France, upon the condition (amongst others) that I, the said
Louis John Crossley, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Louis John Crossley, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement (that is to say) :-
:-
This Invention consists in combining in one instrument the three several
parts of the alphabetical electric telegraphic apparatus known as the bell;
the receiver, and the transmitter, and in constructing and arranging those
parts so that when the instrument is closed any current entering from the line

page_text: wire will ring the bell, and when opened the bell will be thrown out of circuit.
and the receiver placed in circuit, and also in a position for the clerk to receive
the message. The apparatus is in two parts, hinged together in the form of a
box or folding case; the bell is fixed upon the top part covered by a lid, the
receiver is fixed within the same part, and the transmitter in the bottom part.
When the apparatus is closed the bell is in circuit, but when open it is thrown
out, and both the receiver and transmitter are placed in circuit. This is
effected by means of a stud fixed on the receiver, which, when the apparatus
is closed, is in contact with and depresses a spring fixed on the transmitter
communicating with the line wire. When the apparatus is open the stud is
removed out of contact with the spring, which is then at liberty to rise and
come into contact with another stud which is in communication by a wire
with the receiver. Thus, when the apparatus is closed, the current is com-
municated to the bell to call attention, and when opened it is transferred from
the bell to the receiver. By this Invention the several parts of an ordinary.
telegraphic apparatus are combined in one compact portable instrument or
machine.
In witness whereof, I, the said Louis John Crossley, have hereunto set
my hand and seal, this Fifth day of February, One thousand eight
hundred and sixty-six.
LOUIS J. CROSSLEY. (L.S.)
