I, HARRIETTE KEARSLEY, of 32 Ladbroke Grove Road, Notting Hill, in the
County of Middlesex, do hereby declare the nature of my said invention to be as
follows:-
Whereas rubber tyres, as now fitted to velocipedes and other vehicles are subject to
rapid wear, and incapable of sustaining, for any length of time, the rough usage
arising from travelling on macadamised and other uneven roads. The friction arising
from the contact of rubber tyres with such roads also necessitates a great waste of
propelling power and draught. Also the class of rubber used is of a very hard nature
and therefore deficient in elasticity.
-
Now the object of my invention is to remedy such defects by fitting a protective
plate or plates outside the rubber tyre, to sustain the wheel upon a shorter base: to
prevent rapid wear and deterioration of the rubber tyre, and to reduce the power
required to draw or propel the wheels over rough and uneven roads. Moreover, with
my improvements a superior and more elastic kind of rubber may be used or any
other elastic substance.
The plate or plates forming the shield to the outside of the rubber, may be formed
from hoops turned in a lathe, the sectional form of which hoop or hoops corresponds
with that of the rubber tyre. Or the rings may be cast in metal or rolled in bars of
steel, iron, or other suitable material by means of an arrangement of rollers formed to
suit the particular kind of hoop required and of channel or other suitable form, and
welded or otherwise formed into hoops; or such hoops may be built or formed of
several pieces or parts rivetted together.

page_text: The methods of attaching the plate or plates or shields to the tyres may be varied
according to the construction and weight, of the wheel and the purpose to which the
wheel is to be applied and may be effected by means of lugs, flanges, or otherwise;'
the essence of my invention being to provide a metallic medium to enclose the rubber
tyre, and shield the same from contact with the road.
The inside of the shield may be of a dove tail form or may be provided. with a
flange or with projections barbed or wedge shape.
The shield may be of channel iron with projections rivetted to the sides or the
sides may be roughed or corrugated the projections may be of any suitable number
and of any shape.

page_text: I, HARRIETTE KEARSLEY of 32 Ladbroke Grove Road Notting Hill London in the
County of Middlesex, 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:-
Whereas rubber tyres, as now fitted to Velocipedes and other Vehicles are subject
to rapid wear and incapable of sustaining, for any length of time, the rough usage
arising from travelling on macadamised and other uneven roads.
The friction arising from the contact of rubber tyres with such roads also necessi-
tates a great waste of propelling power and draught. Also the class of rubber used
is necessarily of a very hard nature and therefore deficient in elasticity.
Now the object of my invention is to remedy such defects by fitting a protective
hoop or hoops outside of rubber tyre made of similar grooved bars with inside
projections as granted to Robert Kearsley by letters patent Sep. 11. 1883 No. 4352
but with the additional thickness of a tyre bar added to the part which comes in
contact with the road thereby preventing the rapid wear and deterioration of rubber
tyre and to reduce the power required to draw or propel the wheels over rough and
uneven roads. Moreover with my improvements a superior and more elastic kind of
rubber may be used which is more effective in stopping the noise & vibration and
gives additional ease.
The hoop or hoops forming the shield or outside tyre for the rubber may be formed
from hoops turned in lathe the sectional form of which hoop or hoops correspond
with that of the rubber tyre, or the hoops may be cast in metal, or rolled in bars of
steel or Iron and welded into hoops. Or weldless hoops may be rolled in Metal the
bars can be produced by the process of rolling described in letters patent Feby. 8.
1884. No. 2960. or any arrangement of Rolls formed to suit the particular kind of
hoop required and of channel or other suitable form and welded or otherwise formed
into hoops, or such hoops may be built or formed of several pieces or parts rivetted
together.
The inside of the protecting Shield may be of a dovetail form or vertical sides or
any shape that may be required or may be provided with a flange, or with barbed or
wedge shaped projections. When the protecting Shield is formed channel iron or
steel as herein before mentioned it is provided with projections upon or in the sides,
or the sides may be roughed or corrugated or the projections may be of any suitable
number and shape or the projections or ribs may be formed on a plate or plates or
may be attached by any suitable means to the inner sides of the grooves or the sides
may be pierced from the outside with pins, screws or rivetts or springs may be fixed
inside of the grooves or other projections may be formed thereon or therein the

page_text: essence of my invention being to provide a Metallic medium to inclose the rubber tyre
and shield the same from contact with the road and also to prevent the rubber tyre
from moving in the groove on the principal and manner herebefore described.
I do not confine myself to india rubber for tyres as other elastic substances may be
used, and the word india rubber, or rubber tyres, in this specification is intended to
include such other substances. Those tyres are applicable to wheels without the usual
wood felloes by securing them to the wood spokes.
And in order that my said Invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a section shewing one method of carrying out my invention a is the tyre
secured to the wood or other felloes of the wheel and shrunk on in the usual manner
b is the India rubber tyre placed in the tyre a. The tyre c made of any suitable metal
is fixed upon the outside of india rubber tyre and may be formed in one entire piece
or I prefer it in two halves, or it may be in more parts. The hoop d is formed in one
piece by welding or otherwise and shrunk on to the tyre c.
Fig. 2 shows another form in which the section of the tyre c is formed in one piece
instead of that shewn in Fig. 1.
Fig. 3 shews another form with vertical sides.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is
1. The application and use of metallic tyres fitted to and operating as shields to
protect the rubber tyres from wearing and moving in the groove substantially as and
for the purposes herein before described and illustrated on the drawings.
2. The general arrangements and combination of parts together constituting my
improvements in tyres for wheels of velocipedes and other Vehicles, substantially as
hereinbefore described and illustrated on the drawings.
