IM- PROVED CARRIAGE POLES."
Year: 1874

page_text: LETTERS PATENT to James Colverd, of 4, Trinity Buildings, Great
Tower Street, in the City of London, for the Invention of "IM-
PROVED CARRIAGE POLES."
PROVISIONAL SPECIFICATION left by the said James Colverd at
the Office of the Commissioners of Patonts, with his Petition, on
the 21st December 1874.
I, JAMES COLVERD, of 4, Trinity Buildings, Great Tower Street, in
the City of London, do hereby declare the nature of the said Invention
for "IMPROVED CARRIAGE POLES," to be as follows :—
I construct the head of the carriage pole in three pieces, the two
outer or side pieces being of steel, iron, or other suitable material, to
which I attach the pole pieces. The back ends of each side piece are
rounded and fitted with a pin which is received in a socket sunk for that
purpose in the pole to keep the side pieces in their places. I affix iron
plates to the top and bottom of the central piece, the pole hook being

page_text: attached to one of these plates. These plates and the side pieces are
made with a raised collar, as near as practicable to the pole hook, in
which three or four threads of a screw are cut to receive a sliding collar
having corresponding threads cut in the inside and one or more raised
studs on the outside to facilitate its removal. On unscrewing the collar
and sliding it below the junction of the side pieces with the lower part
of the pole, the heads of both horses are simultaneously released by the
side pieces, to which are attached the pole pieces, coming away. I
place a small stud on the pole below the side pieces to prevent the
collar slipping down the pole. The remaining parts of the pole I make
in the ordinary manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Colverd in the Great Seal Patent Office on
the 21st June 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
COLVERD, of 4, Trinity Buildings, Great Tower Street, in the City of
London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patont, bearing date the Twenty-first day of December, in the
year of our Lord One thousand eight hundred and seventy-four, in
the thirty-eighth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said James Colverd, Her special
license that I, the said James Colverd, my executors, administrators,
and assigns, or such others as I, the said James Colverd, 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 "IMPROVED CARRIAGE
POLES," upon the condition (amongst others) that I, the said James
Colverd, 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

page_text: 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 James Colverd, do hereby declaro
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 :-
I construct the head of the carriage pole in three pieces, the two
outer or side pieces being of steel, iron, or other suitable material, to
which I attach the pole pieces. The back end of each side piece is
rounded and fitted with a pin which is received in a socket sunk for that
purpose in the pole to keep the side pieces in their places. I affix metal
plates to the top and bottom of the central piece, the pole hook being
attached to one of these plates. These plates and the side pieces are
made with a raised collar, as near as practicable to the pole hook, on
which three or four threads of a screw are cut to receive a sliding collar
having corresponding threads cut in the inside and one or more raised
studs on the outside to facilitate its removal. On unscrewing the
collar and sliding it below the junction of the side pieces with the lower
part of the pole the heads of both horses are simultaneously released by
the side pieces (to which are attached the pole pieces) coming away. I
place a small stud on the pole below the side pieces to prevent the collar
sliping down the pole. The remaining parts of the pole I make in the
ordinary manner.
In order to prevent the collar working round out of position I drill a
hole through the upper side thereof, provided with a screw thread, and
insert therein a stud or thumbscrew, which thus secures the collar in
one position; or I attach a spring to the upper part of the pole, over
which, on being pressed down, such metal collar slides when the spring
rises, and thus secures the collar in a fixed position; and when desired
to release the horses' heads, it is only necessary to press down the spring
and force back such metal collar to the bottom of the pole, when the
side pieces at once fall away and thus free the horses.

page_text: Having now described the nature of my said Invention and the
manner of performing the same, I wish it to be understood that I claim,
the improvements in carriage poles, substantially in the manner and by
the means herein-before set forth and described.
In witness whereof, I, the said James Colverd, have hereunto set
my hand and seal, this Twenty-first day of June, in the year of
our Lord One thousand eight hundred and seventy-five.
JAMES COLVERD. (L.S.)
