IMPROVEMENTS IN THE CONSTRUCTION OF WHEELS FOR CARRIAGES AND OTHER VEHICLES."
Year: 1875

page_text: LETTERS PATENT to Stephen Thomas Osmond, of Ramsbury, in the
County of Wilts, Agricultural Engineer, for the Invention of
"IMPROVEMENTS IN THE CONSTRUCTION OF WHEELS FOR CARRIAGES AND
OTHER VEHICLES."
PROVISIONAL SPECIFICATION left by the said Stephen Thomas
Osmond at the Office of the Commissioners of Patents, with his
Petition, on the 25th June 1875.
I, STEPHEN THOMAS OSMOND, of Ramsbury, in the County of Wilts,
Agricultural Engineer, do hereby declare the 'nature of the said
Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF WHEELS FOR CARRIAGES
AND OTHER VEHICLES," to be as follows:-
This Invention consists in certain improvements in the construction
of wheels for carriages and other vehicles, the naves or stocks being
formed of cast iron and the other parts of wrought iron.

page_text: The nave or stock is formed of three or in some cases more separate
parts, and essentially consists of the main body, the back of which is
furnished with a flange for securing and holding the spokes, and a loose
box or bush which is provided with flanges thereon, and passed through
the nave or stock and fastened therein by means of screw bolts which
pass through the flanges on the box or bush and fix the same to the
back of the flange by which the spokes are held.
The back portion of the body of the nave or stock is formed with
dovetailed slots therein for the reception of the ends of the spokes,
which are bevelled so as to coincide with the dovetailed slots in which 1
they are inserted.
The felloes which constitute the ring of the wheel are constructed of
channelled iron, the several sections forming the ring being connected
and secured to each other by any suitable means, a plain iron or steel
tyre being fixed on the exterior of the ring.
The spokes have one end thereof bevelled, as before mentioned, such
ends being inserted in the dovetailed slots in the nave or stock, in which
they are tightly held by the means above described, and the opposite
ends thereof are respectively divided and bent in reverse directions and
fitted into the channel in the interior of the ring.
Wheels constructed as herein-before described possess the important
features of strength and simplicity, and economy of manufacture.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Stephen Thomas Osmond in the Great Seal Patent
Office on the 23rd December 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, STEPHEN
THOMAS OSMOND, of Ramsbury, in the County of Wilts, Agricultural
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of June, in the year of a
our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,

page_text: give and grant unto the said Stephen Thomas Osmond, Her special
licence, that I, the said Stephen Thomas Osmond, my executors, admini-
strators, and assigns, or such others as I, the said Stephen Thomas Osmond,
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 OF WHEELS FOR CARRIAGES. AND
OTHER VEHICLES,” upon the condition (amongst others) that I, the
said Stephen Thomas Osmond, 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 Stephen Thomas Osmond, 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,. reference being häd to the
Drawings hereunto annexed, and to the figures and lefters marked
thereon, that is to say :—
"
My said Invention consists in certain improvements in the con-
5 struction of, wheels for carriages and other vehicles, the naves or stocks
of such wheels being formed of cast iron and the other parts thereof of
wrought iron.
The nave or stock is formed of three or in some cases more separate
parts, and essentially consists of the main body, the back of which is
Ofurnished with a flange for securing and holding the spokes, and a loose
box or bush, which is provided with flanges thereon and passed through
the nave or stock and fastened or secured therein by means of screw
bolts which pass through the flanges on the box or bush, or by means of
other suitable contrivances so as to fix the box or bush to the flanges by
which the spokes are held.
The back portion of the body of the nave or stock is formed with
6 dovetailed slots therein for the reception of the ends of the snakes.

page_text: •
Figure 9 is a section of a channelled iron felloe or ring, in the hollows
of which the spokes are fitted.
It may, however, be mentioned that the position of the channelled
iron may be reversed and the outward portion of the felloes themselves
be constructed of a hollow form, the tyre being fixed and bolted or
secured to or on the edge of the same.
Having thus described and ascertained the nature of my said In-
vention, and the manner in which it is to be performed, I would observe
in conclusion that what I consider novel and original, and therefore
claim as constituting the Invention secured to me by the said herein-
before in part recited Letters Patent is, the combination and arrangement
of parts and mechanism in the construction of wheels for carriages and
other vehicles, substantially as herein-before set forth and described, or
any mere modifications thereof.
In witness whereof, I, the said Stephen, Thomas Osmond, have
hereunto set my hand and seal, this 21st day of December,
One thousand eight hundred and seventy-five."
