Year: 1870

page_text: LETTERS PATENT to Henry Kinsey, of the Robin Hood Works,
Nottingham, for the Invention of "IMPROVEMENTS IN WHEELS FOR
CARRIAGES, VEHICLES, AND LOCOMOTIVE APPARATUS, AND IN WHEELS AND
PULLEYS FOR DRIVING MACHINERY."
Scaled the 1st November 1870, and dated the 4th May 1870.
PROVISIONAL SPECIFICATION left by the said Henry Kinsey at the
Office of the Commissioners of Patents, with his Petition, on the
4th May 1870.
I, HENRY KINSEY, of the Robin Hood Works, Nottingham, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN WHEELS
FOR CARRIAGES, VEHICLES, AND LOCOMOTIVE APPARATUS, and IN WHEELS AND.
PULLEYS FOR DRIVING MACHINERY," to be as follows:-
This Invention has firstly for its object to construct a wheel with an
clastic tyre, to enable it to pass over soft ground without sinking to the
same extent as it would if the wheel were formed with a solid tyre, as is

page_text: for the most part usual, and also to give to the tyre an increased hold
on the ground when the wheel is to be used as a driving wheel. For
this purpose I employ a wheel with a solid tyre or circumference,
around which I apply a number of springs, each composed of a strip
of steel bent round into a ring or tube, and by preference I cause the
ends of the strip forming each spring to overlap one another, thus,
The several springs around the tyre are placed around its periphery in
contact with one another, and to hold the springs against the tyre I
embrace them with an outer tyre of spring stecl, or this outer tyre
might be of other flexible material, such as india-rubber or india-rubber
and canvas combined, or the whole of the outer tyre might be made
up of links or shoes jointed together. In order to keep the springs from
slipping off the rigid tyre of the wheel, I provide this tyre with flanges
to come one on either side of the springs, and to retain the flexible or
jointed tyre I introduce into some of the outer angles or hollows
between the adjacent springs pieces with flanges upon them, both to
come on each side of the flexible tyre, and also on each side of the
springs.
In some cases also when a vulcanized india-rubber tyre is placed around
the springs, the inner circumference of such tyre may be formed with
projections upon it to fit between the hollows or angles between the
adjacent springs; such elastic tyre might also be surrounded by an outer
tyre of spring steel, or by shoes of hard material. In some cases also I
surround a rigid wheel with a deep elastic tyre of vulcanized india-rubber,
having holes formed in it, into which springs, by preference such as above
described, are, inserted, and around the exterior of such elastic tyre a
thin elastic tyre of spring steel may be placed; or the elastic tyre of vul-
canized india-rubber may have other holes or perforations formed through
it, and through these pins may be passed to carry shoes or bearing plates
ranged around the exterior circumference of the tyre.
The inner circumference of clastic tyres of vulcanized india-rubber I
also in some cases form with projections upon them to fit into corresponding
hollows in the circumference of the solid tyre, and when such tyres are
formed with holes in them to receive springs, as above explained, I by
preference form such projections of a circular form, concentric with the
holes in which the springs are received.

Pulleys or wheels for driving straps and for friction gearing may
similarly be provided with flexible tyres supported by springs, as herein-
before described.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Kinsey in the Great Seal Patent Office
on the 4th November 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
KINSEY, of the Robin Hood Works, Nottingham, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of May, 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 Henry Kinsey, Her special licence that I, the
said Henry Kinsey, my executors, administrators, and assigns, or such
others as I, the said Henry Kinsey, 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 CARRIAGES,
VEHICLES, AND LOCOMOTIVE APPARATUS, AND IN WHEELS AND PULLEYS FOR
DRIVING MACHINERY," upon the condition (amongst others) that I, the
said Henry Kinsey, 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 Henry Kinsey, 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 tho
following statement thereof, that is to say :—.

page_text: This Invention has, firstly, for its object to construct a wheel with
an elastic tyre to enable it to pass over soft ground without sinking to
the same extent as it would if the wheel were formed with a solid tyre,
as is for the most part usual, and also to give to the tyre an increased
hold on the ground when the wheel is to be used as a driving wheel.
For this purpose I employ a wheel with a solid tyre or circumference,
around which I apply a number of springs, each composed of a strip of
steel bent round into a ring or tube, and by preference I cause the ends
of the strip forming each spring to overlap one another thus ☐ The
several springs around the tyre are placed around its periphery in
contact with one another, and to hold the springs against the tyre I
embrace them with an outer tyre of spring steel, or this outer tyre might
be of other flexible material, such as india-rubber, or india-rubber and
canvas combined, or the whole of the outer tyre might be made up of
links or shoes jointed together. In order to keep the springs from
slipping off the rigid tyre of the wheel I provide this tyre with flanges to
come one on either side of the springs, and to retain the flexible or jointed
tyre I in some cases introduce into some of the outer angles or
hollows between the adjacent springs pieces with flanges upon them,
both to come on each side of the flexible tyre, and also on each side of
the springs.
In some cases also when a vulcanized india-rubber tyre is placed
around the springs the inner circumference of such tyre may be formed
with projections upon it to fit between the hollows or angles between
the adjacent springs; such clastic tyre might also be surrounded by an
outer tyre of spring steel or by shoes of hard material.
At Figure 1 of the Drawings annexed I have shown a side view, partly
in section, of a wheel having a number of tubes of spring metal placed
around its circumference, and embraced by a tyre of vulcanized india-
rubber, which has projections to fit into spaces between the springs as
above described. a is the circumference of the solid portion of the
wheel formed with recesses for the tubular springs 6 to lie in ; c is a
tyre of vulcanized india-rubber, with projections c¹ upon its inner
circumference to fit into spaces between the adjacent springs b; d is a
tyre of thin spring steel surrounding the exterior of the vulcanized
india-rubber tyre; e, e, arc side flanges for retaining the springs b in

page_text: position. These flanges may be fixed in any suitable manner to the solid
part of the wheel.
In some case also I surround a rigid wheel with a deep elastic tyre of
vulcanized india-rubber, having holes formed in it into which springs,
by preference such as above described, arc inserted, and around the
exterior of such elastic tyre a thin elastic tyre of spring steel may be
placed, or the elastic tyre of vulcanized india-rubber may have other
holes or perforations formed through it, and through these pins may be
passed to carry shoes or bearing plates ranged around the exterior
circumference of the tyre.
The inner circumference of elastic tyres of vulcanized india-rubber I
also in some cases form with projections upon them to fit into corre-
sponding hollows in the circumference of the solid tyre, and when
such tyres are formed with holes in them to receive springs as above
explained, I by preference form such projections of a circular form
concentric with the holes in which the springs are received.
Pulleys or wheels for driving straps and for friction gearing may
similarly be provided with flexible tyres supported by springs as herein-
before described. For this purpose I prefer to place the tubes of spring
metal around the circumference of the pulley or wheel, and to embrace
the springs with a flexible steel tyre, and to connect the spring tubes
and the tyre when they meet together with rivets.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that what I claim
as my improvements in wheels for carriages, vehicles, and locomotive
apparatus, and in wheels and pulleys for driving machinery is,-
1. Placing round the circumference of a rigid wheel a number of
tubes of spring metal, and embracing such tubes with a flexible tyre,
substantially as herein described.
2. Placing around the circumference of a rigid wheel a number of
tubes of spring metal, and embracing such tubes with a tyre of vulcanized
india-rubber, having projections on its inner circumference to fit into
spaces between the tubes substantially as herein described.
3. Placing around the circumference of a rigid wheel a deep tyre of
vulcanized india-rubber with holes formed transversely through it, into
which tubes of spring metal arc inserted.

page_text: 4. Forming projections on the inner circumference of vulcanized india-
rubber tyres to fit into corresponding recesses in the periphery of a solid
wheel.
In witness whereof, L, the said Henry Kinsey, have hereunto set
my hand and seal, this Fourth day of November, in the year of 5
our Lord One thousand eight hundred and seventy.
