I, JOHN UTBER BURT of No. 23 Swinton Street, Kings Cross, in the County of
Middlesex Coach Builder, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the tyres of wooden wheels such as are used for
carriages and other vehicles, the object which I have in view being to provide for
fixing the tyre securely on the wheel without screws, rivets or other fastenings,
without weakening or damaging the felloes and with protection to the felloes
against damage from kerbs or other lateral obstructions. For this purpose, in
forming the tyre I use a bar of iron or steel which has at one edge of it a light
flange or projecting lip. I bend this bar and weld it in the usual way to form a
complete ring, and I turn the circumference of the felloes preferably with a slight
slope inwards, that is to say with the diameter next the vehicle a little less than
that farthest from the vehicle. I heat the tyre so as to expand it and lay it on a
flat surface; I then drop the wheel into the heated tyre, which I cool while gently
tapping it with a hammer. The tyre shrinking binds itself firmly on the wheel, its
flange preventing it from shifting in the one direction and the slight conical form of
the felloes preventing it from shifting in the other direction.

An Improvement in Tyres for Wheels of Carriages and other
Vehicles.
I, JOHN UTBER BURT of No. 23 Swinton. Street, Kings Cross in the County of
Middlesex, Coach Builder, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention relates to the tyres of wooden wheels such as are used for carriages
and other vehicles, the object which I have in view being to provide for fixing
the tyre securely on the wheel without screws, rivets or other fastenings, without
weakening or damaging the felloes and with protection to the felloes against
damage from kerbs or other lateral obstructions.
•
For this purpose in forming the tyre I use a bar of iron or steel which has at
one edge of it a light flange or projecting lip. I bend this bar and weld it in the
usual way to form a complete ring, and I turn the circumference of the felloes
preferably with a slight slope inwards, that is to say with the diameter next the
vehicle a little less than that farthest from the vehicle. I heat the tyre so as to
expand it and lay it on a flat surface; I then drop the wheel into the heated tyre
which I cool while gently tapping it with a hammer The tyre shrinking binds
itself firmly on the wheel, its flange preventing it from shifting in the one direction
and the slight conical form of the felloes preventing it from shifting in the other
direction.
The accompanying drawing shews the section of a felloe and tyre constructed
according to my invention.
The tyre A is made with an inwardly projecting lip or flange A¹ and its diameter
at A is slightly smaller than at A³, the felloe B being turned with a slight slope to
correspond. On heating the tyre it expands sufficiently to allow the felloe to enter
through A2 so that when the tyre is shrunk on, it is held securely on the one side
by the flange A¹ and on the other side by the tapering form of the felloe..
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
A tyre having on its one edge an inwardly projecting flange or lip and having
its inner surface formed of slightly smaller diameter at the edge opposite the flange
than at the edge next the flange, substantially as and for the purpose set forth.
