PROVISIONAL SPECIFICATION.
Improvements in the Construction of Tyres of Wheels for Bicycles,
Tricycles, and other Road Vehicles.
I, DAVID MARSH SKINNER of 49 Church Street, Bolton in the County of
Lancaster, Ironmonger, do hereby declare the nature of my said invention to be as
follows:-
My invention consists in constructing the tyres of wheels for bicycles, tricycles,
and other road vehicles in a novel and unique manner, and is designed to supersede
or improve the construction of pneumatic or other inflated tyres at present in
vogue. It is well known that inflated tyres are liable to become damaged and cut
when travelling over rough roads, consequently are uncertain in their action, which
is a source of great annoyance and trouble, often resulting in the cycle or vehicle
having to be wheeled or carried home or elsewhere for repairs. My invention is
intended to entirely dispense with these defects, which I accomplish by enclosing
or otherwise covering the india-rubber or other inflating tube with a tube or
casing of copper, steel, or other pliable or suitable metal, with the ends so con-
structed that they fit or lock together when the india-rubber or other tube is
inflated to its full extent. The casing can be of such a size as to cover or lap
over the inflating tube sufficiently to prevent the same coming in contact with the
road. The ends of the metallic tube or casing can be secured together mechanically
or otherwise. After the metallic tube or casing has been placed over or on the
inflating tube they are enclosed or covered with canvas; the latter having an india-
rubber facing on the outer surface bearing on the road, to protect the canvas
and prevent absorbtion of liquid when travelling on wet or damp roads or other
places.

I, DAVID MARSH SKINNER of 49 Church Street, Bolton in the County of

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
My invention consists in constructing the tyres of wheels for bicycles, tricycles,

or otherwise. After the metallic tube or casing has been placed over or on
the inflating tube they are enclosed or covered with canvas; the latter having
an india-rubber facing on the outer surface bearing on the road to protect the
canvas and prevent absorbtion of liquid when travelling on wet or damp roads or
other places.
Fig. 1 is a sectional elevation of a wheel for bicycles, tricycles, and other road
vehicles with a pneumatic tyre enclosed or encased on my improved principle.
Fig. 2 is an enlarged section through line A B in Fig. 1.
Fig. 3 is an enlarged section through joint when a metallic tube or casing is
employed.
Fig. 4 is a sectional plan of locking joint as in Fig. 3.
Fig. 5 is a part sectional elevation through line CD in Fig. 4, and
Fig. 6 is a sectional plan of joint of casing or covering without locking joint.
E is the centre of the wheel; G the spokes; H the rim, and I the inflatable
tube. To prevent the inflatable tube I being cut or damaged when travelling over
rough roads I enclose the same in the tube or casing K composed of either copper,
steel, or other pliable or suitable metal or material, such as celluloid, xylonite, or
other substance or material of a gelatine nature that will resist nails, tacks, and
other sharp instruments met with on roads when travelling. The tube K is pro-
vided on its inner periphery with the over-lapping joint L to allow of the same
giving and taking according to the diameter the inflatable tube I may assume when
expanded by pressure. The tube K may be composed of one or more sections or
segments to form the circle; each joint being secured as shown in Figs. 3, 4, and 5.
Each joint is formed by providing one end of the tube K or a section or segment
thereof with the slots M and P. In the latter slot fits the pin or projection N on
the end coupling with the same. The piu or projection N is secured to the tube K
by rivetting or other means. The slot M is angular in form, and to place the
pin N in the slot P in the position shown in Fig. 4 the tube K has to be slightly
twisted to admit of the pin N being passed through the slot M to the longitudinal
slot P. The latter is made sufficiently long to allow of the pin N sliding to and
fro according to the action of the tube K when travelling, or according to the
increasing or decreasing diameter of the inflatable tube I when under pressure. If
desired the joint, or joints, can be formed without the slots M and P and the pin N,
which I effect by passing the end of one into the end of the other as shown in
Fig. 6, the over-lap being sufficiently long to allow for expansion and contraction
of the varying diameters of the inflatable tube. After the tube K has been placed
round the inflatable tube I the former is enclosed or covered with the canvas R,
the latter being secured by cement or otherwise. To protect the outer surface of
the canvas R, bearing on the road, from damp or wet roads and from absorbing
liquid it is provided with the facing of india-rubber T as shown in Figs. 1 and 2 ;
the same being secured by cement or other means.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. Enclosing an inflatable tyre in a tube of metal or other pliable material
with the internal periphery provided with an over-lapping joint, substantially as
described.
2. In an inflatable tyre enclosed in a tube of metal or other pliable material
with the internal periphery provided with an overlapping joint, the use of the
slots M and P and the pin N for the purpose specified, substantially as described.
