PROVISIONAL SPECIFICATION.
Improvements in the Construction of Tires for Wheels and in the
Method of Fixing them thereto.
.
I WILLIAM AUSTIN COLCLOUGH, Coach Builder of 23, Duke Street Dublin do hereby
declare the nature of the said invention for "IMPROVEMENTS IN THE CONSTRUCTION OF
TIRES FOR WHEELS, AND IN THE METHOD OF FIXING THEM THERETO to be as follows:-
I construct my improved tires in a plano-concave form or section the concave face
or surface being next the periphery or rim of the wheel, which I make of a convexity
proportionate to the concavity of the tire, so that one shall fit the other.
The tire being made sufficiently hot is placed whilst in this state round the wheel,
and in cooling it shrinks tightly round the wheel and becomes thoroughly and
permanently fixed thereto; by this means the use of rivets, drilling, or dowelling of
the felloes is avoided, which tend to weaken, or split them, whilst at the same time
their shifting is guarded against.

COMPLETE SPECIFICATION.
Improvements in the Construction of Tires for Wheels and in the
Method of Fixing them thereto.
I WILLIAM AUSTIN COLCLOUGH, Coach Builder of 23 Duke Street Dublin do
bereby declare the nature of the said invention for "IMPROVEMENTS IN THE CON-
STRUCTION OF TIRES FOR WHEELS, AND IN THE METHOD OF FIXING THEM THERETO,
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
I construct my improved tires in a plano-concave form or section, the concave face
or surface being next the periphery or rim of the wheel, which I make of a convoxity
proportionate to the concavity of the tire, so that one shall fit the other.
The tire being made sufficiently hot, is placed whilst in this state round the wheel,
and in cooling, it shrinks tightly round the wheel, and becomes thoroughly and
permanently fixed thereto.
By this method no rivets are required, consequently the tire requires no drilling,
nor are dowels in the felloes necessary, the tires cannot shift, or come off, moreover,
it will have a decided tendency to prevent the felloes splitting, or their joints shifting.
Fig. 1 of the accompanying drawings is an elevation showing part of a wheel with
my improved concave tire applied thereto. Fig. 2 being a section of the spoke felloe
and tire, and Fig. 3 representing a section of the tire.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I claim
The construction of tires of wheels with a concave inner face, to closely fit the
convex surface of the periphery of the wheel.
.
I claim also the method of fixing the said tires to the wheels, by first expanding
[Price 6d1

traction or shrinking on the wheel when cold rendering them perfectly and permanently
fixed and secure, without the aid of rivets or drilling, and so avoiding weakening the
tires.
