IMPROVEMENTS IN METALLIC STANDARDS OR POSTS FOR ELECTRIC TELEGRAPHS AND SIGNAL MASTS
Year: 1868

page_text: LETTERS PATENT to Samuel Sharrock, of Liverpool, in the County of
Lancaster, Engineer, for the Invention of "IMPROVEMENTS IN METALLIC
STANDARDS OR POSTS FOR ELECTRIC TELEGRAPHS AND SIGNAL MASTS."
Sealed the 15th January 1869, and dated the 4th September 1868.
PROVISIONAL SPECIFICATION left by the said Samuel Sharrock at
the Office of the Commissioners of Patents, with his Petition, on
the 4th September 1868.
I, SAMUEL SHARROCK, of Liverpool, in the County of Lancaster,
Engineer, do hereby declare the nature of the said Invention for "Ix-
PROVEMENTS IN METALLIC STANDARDS OR POSTS FOR ELECTRIC TELEGRAPHS AND
SIGNAL MASTS," to be as follows:-
This Invention consists of improvements in metallic standards or posts
for electric telegraphs and signal masts, and consists in constructing them
substantially as herein shewn and described. In the case of the electric
telegraph posts they are intended for carrying the wires over wide rivers
or other places where a considerable space and height is necessary, and

page_text: in the case of signal masts or standards they are intended for erection on
land for signalling for war or other purposes. The central upright I
make of iron or steel in convenient lengths, all fitted together and of
the tubular form, the lengths being attached by means of flanges, which
only require bolting or rivetting together so as to give a minimum
amount of trouble in putting them together, and by means of the rudest
labour at the place of erection. In the case of telegraph masts, as well
as the signal masts where considerable height is required, I truss or brace
the central uprights by means of iron or steel truss rods, which are
tightened and adjusted by means of stretching screws. I also brace the
standards or masts from the upper end to screw moorings by means of
iron or steel rods or wire rope and stretching screws.
Drawing No. 1 shews a signal standard, and Drawing No. 2 shews an
electric telegraph standard made according to my Invention; they can
be readily erected without staging by means of a pair of shear legs after
the sockets have been fixed in the ground and the masts of standards
have been secured together when lying on the ground. I provide an
iron or steel ladder in the case of lofty standards for ascending to the top
to fix the insulators or wires.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Sharrock in the Great Seal Patent Office
on the 3rd March 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
SHARROCK, of Liverpool, in the County of Lancaster, Engineer, send
.greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of September, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Samuel Sharrock, Her special licence
that I, the said Samuel Sharrock, my executors, administrators, and
assigns, or such others as I, the said Samuel Sharrock, my executors,
administrators, and assigns, should at any time 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
METALLIC STANDARDS OR POSTS FOR ELECTRIC TELEGRAPHS AND SIGNAL MASTS,'
upon the condition (amongst others) that I, the said Samuel Sharrock,
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 immc-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Samuel Sharrock, 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 thereof, that is to say :-
This Invention consists of improvements in metallic standards or posts
for electric telegraphs and signal masts, and consists in constructing them
substantially as herein shown and described. In the case of the electric
telegraph posts they are intended for carrying the wires over wide rivers
or other places where a considerable span and height is necessary, and
in the case of signal masts or standards they are intended for erection on
land for signalling for war or other purposes. The central upright I
make of iron or steel in convenient lengths, all fitted together and of
the tubular form, the lengths being attached by means of flanges, which
only require bolting or rivetting together so as to give a minimum
amount of trouble in putting them together and by means of the rudest
labour at the place of erection. In the case of telegraph masts, as well
as the signal masts where considerable height is required, I truss or brace
the central uprights by means of iron or steel truss rods, which are
tightened and adjusted by means of stretching screws. I also brace the
standards or masts from the upper end to screw moorings by means of
iron or steel rods or wire rope and stretching screws.
Drawing No. 1 shows a signal standard and Drawing No. 2 shows an
clectric telegraph standard made according to my Invention; they can
be readily crected without staging by means of a pair of shear legs after
the sockets have been fixed in the ground, and the masts or standards
have been secured together when lying on the ground. I provide an

page_text: iron or steel ladder in the case of lofty standards for ascending to the top
to fix the insulators or wires.
In witness whereof, I, the said. Samuel Sharrock, have hereunto set
my hand and seal, this First day of March, in the year of our
Lord One thousand eight hundred and sixty-nine.
SAMUEL SHARROCK. (L.s.)
