IMPROVEMENTS IN THE CON- STRUCTION AND MANUFACTURE OF WHEELS FOR VEHICLES
Year: 1870

page_text: LETTERS PATENT to John Howard Kidd, of Bangor Iscoyd, in the
County of Flint, for the Invention of." IMPROVEMENTS IN THE CON-
STRUCTION AND MANUFACTURE OF WHEELS FOR VEHICLES,"
PROVISIONAL SPECIFICATION left by. the said John Howard Kidd
at the Office of the Commissioners of Patents, with his Petition, on
tlie 27th January 1870.
I, JOHN HOWARD KIDD, of Bangor Iscoyd, in the County of Flint,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE CONSTRUCTION AND MANUFACTURE OF WHEELS FOR VEHICLES," to be as
follows:
.i
The object of my Invention is to form wheels of metal having tyres
of india-rubber, and consists in making the wheels by casting the boss,
spokes, and rim all in one picce (either solid or hollow) and then
applying the india-rubber tyre, and making it firmly adhere by the
vulcanizing process. I prefer to use for the wheels cast iron, or cast
iron afterwards made malleable by annealing.

page_text: In casting the wheel I form an axle box in the boss or nave by coring
it or by casting it upon a chill. In either case I arrange to have the
boxes and axles so correct as to be interchangeable.
Sometimes I form the spokes of the wheel of wrought iron, hollow
or solid, and lay them in the sand or mould to run the rim and boss to
them. In all cases I finish the wheels by coating them with vulcanized
india-rubber tyres.
I sometimes cast the axle boxes separate and secure them in the
naves by wedges of wood, or I place india-rubber between the axle box
and the nave, which may be vulcanized in position, and further secure 1
the axle box in the nave by flanges and bolts or other suitable means if
required.
SPECIFICATION filed in pursuance of the conditions of the Letters Patent,
and of an Order of the Lord Chancellor, by the said John Howard
Kidd in the Great Seal Patent Office on the 26th August 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HOWARD KIDD, of Bangor Iscoyd, in the County of Flint, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of January, in the
year of our Lord One thousand eight hundred and seventy, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Howard Kidd, Her special
license that I, the said John Howard Kidd, my executors, adminis-
trators, and assigns, or such others as I, the said John Howard Kidd,
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 THE CONSTRUCTION AND MANUFACTURE OF WHEELS FOR
VEHICLES," upon the condition (amongst others) that I, the said John
Howard Kidd, by an instrument in writing under my hand and soal,
should particularly describe and ascertain the nature of the said In-
vention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Scal Patent Office within seven

page_text: calendar months next and immediately after the date of the said Letters
Patent.
'NOW KNOW YE, that I, the said John Howard Kidd, do hereby
declare the nature of my 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 :―
The object of my Invention is to form wheels of metal having tyres
of india-rubber, and consists in making the wheels by casting the boss,
spokes, and rim all in one piece (either solid or hollow), and then
applying the india-rubber tyre, and making it firmly adhere by the
vulcanizing process. I prefer to use for the wheels cast iron, or cast
iron afterwards made malleable by annealing.
In casting the wheel I form an axle box in the boss or nave by coring
it accordingly or by casting it upon a chill; in cither case I arrange to
have the boxes and axles so correct as to be interchangeable.
Sometimes I form the spokes of the wheel of wrought iron, hollow or
solid, and lay them in the sand or mould to run the rim and boss to
them. In all cases I finish the wheels by coating them with vulcanized
india-rubber tyres.
I sometimes cast the axle boxes separate, and secure them in the
naves by wedges of wood, or I place india-rubber between the axle box
and the nave, which may be vulcanized in position, and further secure
the axle box in the nave by flanges and bolts or other suitable means
if required.
My improved wheels may be used for all ordinary vehicles, but are
particularly adapted for omnibusses, Bath chairs, velocipedos, and
perambulators.
In witness whereof, I, the said John Howard Kidd, have hereunto
set iny hand and seal, this Twenty-second day of August, in
the year of our Lord One thousand eight hundred and seventy.
