Year: 1856

page_text: LETTERS PATENT to John Hamilton, junior, of Liverpool, for the Inven-
tion of "IMPROVEMENTS IN THE POSTS OR UPRIGHTS EMPLOYED IN CON-
STRUCTING ELECTRIC TELEGRAPHS."
Sealed the 18th April 1856, and dated the 16th January 1856..
PROVISIONAL SPECIFICATION left by the said John Hamilton at the
Office of the Commissioners of Patents, with his Petition, on the 16th
January 1856.
I, JOHN HAMILTON, jun'; of Liverpool, do hereby declare the nature of
the Invention for "IMPROVEMENTS IN THE POSTS OR UPRIGHTS EMPLOYED IN
CONSTRUCTING ELECTRIC TELEGRAPHS" to be as follows:—
This Invention consists of improvements in the posts or uprights employed
in constructing electric telegraphs, for which purpose each post or upright is
constructed as follows:-A cast-iron plate or foot is formed with an upright
tubular socket; such socket is at its lower parts made with openings, so that
the earth may fall through and fill in the interior of such socket. The
upper part of the post or upright is made of a tube of wrought iron, by pre-
ference coated with zinc, and its lower end enters the socket, and is fixed
thereto by rivets, or otherwise. The socket rises to some inches above the
earth. The top of the post is covered in with a cap, to throw off the rain from
the post, and a transverse bar or bars of wood is or are fixed to the upper part
of the post or upright to receive the wires.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HAMILTON, junior, of Liverpool, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of January, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Hamilton, Her special licence that I, the said John
Hamilton, my executors, administrators, and assigns, or such others as I,
the said John Hamilton, 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 "IMPROVE-
MENTS IN THE POSTS OR UPRIGHTS EMPLOYED IN CONSTRUCTING ELECTRIC TELE-
GRAPHS," upon the condition (amongst others) that I, the said John Hamilton,
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 John Hamilton, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and. ascertained in and by the following
statement thereof, that is to say :-
This Invention consists of improvements in the posts or uprights employed
in constructing electric telegraphs, for which purpose each post or upright is
constructed as follows:-A cast-iron plate or foot is formed with an upright
tubular socket; such socket is at its lower parts made with openings, so that
the earth may fall through and fill in the interior of such socket. The upper
part of the post or upright is made of a tube of wrought iron, by preference
coated with zinc, and its lower end enters the socket, and is fixed thereto by
rivets, or otherwise. The socket rises to some inches above the earth. The
top of the post is covered in with a cap, to throw off the rain from the post,

page_text: and a transverse bar or bars of wood is or are fixed to the upper part of the
post or upright to receive the wires.
Having thus stated the nature of my said Invention, I will proceed to
describe more fully the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shows an electric telegraph post, constructed of tubular wrought
iron, and fixed according to my Invention. Figure 2 shows the lower portion
of the post, which is formed with holes through it, in order that the earth may
fall through and aid in the fixing of the post and parts. In Figure 2 it will be
seen that the foot is made by the passage of the parts A, A, through the lower
part of the tubular post to form the feet; or in place of such parts A, A, a cast-
iron plate or foot may be formed in a suitable manner for having the tubular
perforated post fixed thereto; or, if preferred, such foot may be cast with a
tubular socket, suitable for receiving and having fixed thereto the tubular post;
or the foot may be cast so as to receive the hollow upright thereon, and so that
it may be fixed by a hoop, or otherwise. The arms for suspending the tele-
graph wires may be of wood, and fixed in any suitable manner; the Drawing
shows the arms to be of metal, such as have been lately invented. Figures 3,
4, and 5 show arms of metal suitable for being fixed to the upper part of the
post, as is shewn at Figure 1; but in place of such arms, others of wood may
be used.
I, however, recommend iron arms, particularly those shown at
Figures 4 and 5, as the ends of the metal arms form metal caps for covering
the glass or earthenware insulating instruments.
Having thus described the nature of my said Invention, and the manner of
performing the same, I would have it understood that what I claim is, the
manufacture of electric telegraph wrought-iron tubular posts, as herein
described.
In witness whereof, I, the said John Hamilton, have hereunto set my
hand and seal, this Twenty-second day of April, in the year of our
Lord One thousand eight hundred and fifty-six.
