page_text: LETTERS PATENT to Louis Sterne, of Great Queen Street, in the City
of Westminster, Engineer, for the Invention of "IMPROVEMENTS IN
THE MEANS OF SECURING ELASTIC TYRES TO WHEELS."
THE MEANS OF SECURING ELASTIC TYRES TO WHEELS."
Sealed the 22nd November 1870, and dated the 1st October 1870.
PROVISIONAL SPECIFICATION left by the said Louis Sterne at the
Office of the Commissioners of Patents, with his Petition, on the
1st October 1870.
I, LOUIS STERNE, of Great Queen Street, in the City of Westminster,
Engineer, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN THE MEANS OF SECURING ELASTIC TYRES TO WHEELS," to be as
follows:-
The main object of my Invention is to provide simple and efficient
means of securing elastic tyres to wheels; and my Invention consists in
the employment of wrought iron or other metal staples or bolts which
are free to slide or move inwards when the portions of the tyre to which
they are fitted yield under the pressure of the weight of the carriage.
When I make use of staples the two sides of the staple are carried down

page_text: the two sides of the elastic tyre and of the metal rim of the wheel,
which is recessed to receive them, or is provided with lugs to receive
them, and they are fastened by a transverse bolt or pin. When I make
use of bolts I provide them with a broad head or plate preferably of the
width of the tyre, and carrying them radially through the tyre and
through the felloe of the wheel, and I secure their inner ends by nuts or
otherwise.
My Invention applies to elastic tyres whether made of complete bands
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Louis Sterne, in the Great Seal Patent Office on the
31st March 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LOUIS
STERNE, of Great Queen Street, in the City of Westminister, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of October, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Louis Sterne, Her special licence,
that I, the said Louis Sterne, my executors, administrators, and assigns,
or such others as I, the said Louis Sterne, 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 MEANS OF
SECURING ELASTIC TYRES TO WHEELS," upon the condition (amongst others)
that I, the said Louis Sterne, 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 Louis Sterne, 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 thereof, reference being had to the accompanying
Drawings, that is to say :--
The main object of my Invention is to provide simple and efficient
means of securing elastic tyres to wheels; and my Invention consists
in the employment of wrought iron or other metal staples or bolts
which are free to slide or move inwards when the portions of the tyre
to which they are fitted yield under the pressure of the weight of the
carriage. When I make use of staples the two sides of the staple
are carried down the two sides of the elastic tyre and of the metal rim
of the wheel, which is recessed to receive them, and is provided with
lugs or guides to receive them, and they are fastened by transverse bolts
or pins.
In the accompanying Sheet of Drawings Figure 1 is a side elevation,
Figure 2 a front elevation, and Figure 3 a transverse section of a wheel
provided with an elastic tyre, which is secured by means of sliding
staples, as herein-before described.
a, a, is the rim of the wheel, and b, b, is the elastic tyre, which is by
preference made in segments, but it may be a band or ring made in one
piece; c, c, are the sliding staples, the two sides of which are as before
stated carried down the two sides of the elastic tyre b and of the rim a,
which latter is formed with guides d, d, to receive them; e, e, are
transverse bolts or pins connecting the two sides of each staple c near
their inner ends.
These bolts pass through radial slots f,f, formed in the sides of the
rim a, the slots give sufficient play to the bolts to allow the staples to
slide inwards.
When I make use of sliding bolts instead of staples I provide them
with broad heads or plates, as seen in section in Figure 4, and in plan in
Figure 5 g, g, being the bolts and h, h, the broad heads, which are
preferably of the width of the tyre b, and I carry the bolts radially
through the tyre and through the rim or felloe a of the wheel, and
secure their inner ends by nuts i or otherwise. To prevent the heads h, h,
of the bolts slewing round the bolts may be made square or of other
equivalent form in section, their inner ends being round to receive the

page_text: nuts; the apertures for the bolts in the elastic tyre and in. the metal.rim
would also be made of square or equivalent form..
When the elastic tyres are constructed of segmental rubber blocks
chemically united to metal plates, as described in the Specification of
my Patent of 1st March 1870, No. 599,. the means herein-before described
may be employed as an additional security in case the said blocks should
become loose..
In witness whereof I, the said. Louis Sterne; have hereunto set my
hand and seal, this First day of March One thousand eight
hundred and seventy-one..
