IMPROVEMENTS IN WHEELS FOR COMMON ROAD VEHICLES
Year: 1874

page_text: LETTERS PATENT to Alfred Diss, of West Bergholt, in the County of
Essex, Builder and Contractor, for the Invention of "IMPROVEMENTS
IN WHEELS FOR COMMON ROAD VEHICLES."
Sealed the 14th August 1874, and dated the 17th June 1874.
PROVISIONAL SPECIFICATION left by the said Alfred Diss at the
Office of the Commissioners of Patents, with his Petition, on the
17th June 1874.
I, ALFRED DISS, of West Bergholt, in the County of Essex, Builder
and Contractor, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN WHEELS FOR COMMON ROAD VEHICLES," to be as follows:-
This Invention has for its object the strengthening and protecting
from injury of whicels of common road vehicles, and consists essentially
in protecting the outer face of the fellocs and tyre by the application to.
the outer surface of the felloe of a wrought-iron or malleable metal or
steel guard ring, which is bolted, screwed, or otherwise attached to the
outer face or side of the felloe. This guard ring should by preference

page_text: be of a cross section, curved on the outer side, and flat on its inner face
so as to fit closely against the side of the felloe, and present no abrupt
projection on its outer face. By the application of such a guard ring to
a wheel its strength will be obviously increased, and as the ring itself
receives all the friction due to the contact of the wheel with kerbs or
other stones or posts in the road the life of the wheel is considerably
prolonged at a trifling expense.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Diss in the Great Seal Patent Office on
the 14th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
DISS, of West Bergholt, in the County of Essex, Builder and Contractor,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of June, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Alfred Diss, Her special
license that I, the said Alfred Diss, my executors, administrators,
and assigns, or such others as I, the said Alfred Diss, 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 WHEELS FOR COMMON ROAD VEHICLES," upon the condition (amongst
others) that I, the said Alfred Diss, 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.

page_text: NOW KNOW YE, that I, the said Alfred Diss, 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, reference being had to the accompanying
Drawings, and to the letters and figures marked thereon, that is to
say :—
My said Invention has for its object the strengthening and protecting
from injury of wheels of common road vehicles, and consists essentially
in protecting the outer face of the felloes and tyre by the application to
the outer side or face of the felloe of a wrought iron or malleable metal
or steel guard ring, which is bolted, screwed, or otherwise attached to
the outer side of the felloe. This guard ring should by preference be of
a cross section curved on the outer side and flat on its inner face so as to
fit closely against the side of the felloe, and present no abrupt projection
on its outer face. By the application of such a guard ring to a wheel
its strength will be obviously increased, the several parts of the rim
being securely braced or tied together, and as the guard ring itself
receives all the lateral friction due to the contact of the wheel with kerbs
or other stones or posts in the road the life of the wheel is considerably
prolonged at a trifling expense.
And in order that my said Invention may be fully understood I shall
now proceed more particularly to describe the same, and for that purpose
shall refer to the several Figures on the explanatory Sheet of Drawings
hereunto annexed, the same letters of reference indicating corresponding
parts in all the Figures.
Figure 1 of my Drawings represents a side elevation of a wheel with
my "wheel guard" applied thereto; Figure 2 is a corresponding vertical
section of the same; Figure 3 is a sectional detail showing the felloc
and guard full size; and Figure 4 represents sections of guards (full
size) for various sizes of wheels.
a represents the nave; b, b, the spokes; c, the felloe; and d, the tyro
of an ordinary wooden wheel. To the outer side or face of the felloc I
secure in any convenient or suitable manner my "wheel guard" e,
which consists simply of a ring of steel, wrought iron, or malleable cast
iron, by preference of the section shown in Figure 4, so that when
secured with its flat side or face against the outer side of the felloe, as
shown clearly in Figure 3, there will be no angular projecting parts.

"
The mode which I prefer to adopt for securing these "wheel guards
to the felloes consists in passing bolts f (Figure 3) having conical heads g
through countersunk or conical bolt holes in the guard e, and through
bolt holes in the felloe, the heads of the bolts fitting snugly inside the
said bolt holes in the guard, and being flush with the outer covered
surface thereof, as shown in Figure 3, so as to present no projecting
obstruction. On the inner side of the felloe a metal washer h (more or
less bevelled or cut away, according to the angle of the back face of the
felloe) is slipped over the end of each bolt,, which is then tightened up by
the nut i. '
It is obvious that these "wheel guards" may be made of various
sections, and may be secured to the outer faces of the wheel felloe in
various ways, and therefore I do not confine or restrict myself to the
peculiar sections shown in Figure 4, nor to the particular mode of
securing or attaching the guards shown in Figure 3.
-
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that what I consider
to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent is,―
First. The construction and use of wheels for common road vehicles,
wherein the felloes are protected and strengthened by the application
thereto of a "wheel guard," substantially in the manner and for the
purpose herein-before described and illustrated by the Drawings hereunto
annexed.
Second. The application to existing wheels for common road vehicles
of "wheel guards," substantially as and for the purpose herein-before
described and illustrated by the Drawings hereunto annexed.
In witness whereof; I, the said Alfred Diss, have hereunto set my
hand and seal, this Twelfth day of December, in the year of
our Lord One thousand eight hundred and seventy-four.
