PROVISIONAL SPECIFICATION.
Improvements in Inflated Tyres for the Wheels of Velocipedes and
other Carriages.
I, WILLIAM HILLMAN, of Stoke Green, Coventry, in the County of Warwick,
Managing Director of Works, do hereby declare the nature of this invention to be
as follows:-
This invention has for its object the improvement of inflated tyres for velocipedes
and other carriages to render them easier to attach to, and detach from, the felloe
of the wheel, and also to cheapen their cost.
In carrying out my invention, I take a tube of rubber or other similar material
of sufficient length to encircle the wheel to be tyred, and fix in any convenient
position on the inner side, a small screwed injection socket or nozzle, which is in the
form of a hollow screw with large diameter but thin head, and having a loose
washer and nut, by means of which and a little cement a perfect joint can be made
in the tube. On the screwed shank of the socket or nozzle I attach a short length
of flexible tube, which is preferably projected through the felloe of the wheel.
Instead of the valve which is generally used to prevent the escape of the air or gas
which has been injected, I attach to the injection tube, a screw clamp, having a
loose pressure piece in the end of its screw; the loose piece is preferably D shaped,
and after the tyre has been inflated, the screw has simply to be turned a few times
to prevent any escape of the air or gas. After jointing up the tube in the form of
a ring and partially inflating it, I place it in the felloe, which may be of the usual
semicircular or grooved shape, and I then bind it round the entire circumference in
a spiral form with strip leather or strip india rubber, webbing, or other suitable
material, but preferably of leather or compounded non-stretching india rubber,
as these latter materials prevent lateral slipping when the tyres are used on
bicvcles.
When the tyres are made for use on very rough or stony roads, I prefer to bind
them spirally before putting them into the felloe as well as afterwards. Without
limiting the expansion of the rubber tube by some means, the necessary compression
of the air or gas cannot be obtained, and by my improved method of spiral binding,
it can be done by any unskilled person and cheaper than by the present known
means.

Improvements in Inflated Tyres for the Wheels of Velocipedes and
other Carriages.
I, WILLIAM HILLMAN, of Stoke Green, Coventry, in the County of Warwick,
Managing Director of Works, 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 :-
This invention has for its object the improvement of inflated tyres for velocipedes
and other carriages to render them easier to attach to and detach from the felloe of
the wheel and also to cheapen their cost.
In carrying out my invention I take a tube of india rubber of sufficient length

page_text: Figure 1 18 a cross section of a wheel telloe fitted with an inflated tyre having my
improvements applied thereto.
Figure 2 is a longitudinal section, and Figure 3 is a side elevation of the
same, and
Figure 4 is a plan of the screw clamp separately.
a is the felloe of the wheel, b is an india rubber tube, which is of sufficient length
to encircle the wheel to be tyred, and which is connected at the ends in any con-
venient or well known manner. I fix in any convenient position in such tube at the
inner side of the tyre, a small screwed injection nozzle or socket, which is in the
form of a hollow screw c, with a thin head c' of large dimensions, having a loose
washer and nut c³ by means of which and a little cement, a perfect joint can be
made in the tube.
In placing this injection socket or nozzle in position, a hole is first made in the
tube b, the screw c is pushed through the same from the inside of the tube, the
washer is then placed over the screw c on the outside of the tube, and the nut
is screwed down, so as to bind the said parts firmly together with part of the tube b
between the head c' and the washer c².
I also form the head c¹ and loose washer c² of shape to fit closely the inside of the
tyre. On the screwed shank c of the socket or nozzle, I attach a short length of
flexible tube d, which is passed through a hole in the felloe a of the wheel, and the
nut c³ is caused to occupy such hole, so as to avoid as much as possible any distortion
of the tube b by the nozzle fittings.
Instead of the valve which is generally used to prevent the escape of the air or
gas which is injected into the tube b, I attach to the tube d, a screw clamp e having
a loose pressure piece e¹ loosely rivetted to the end of a screw e³, and somewhat
of D form. The screw 2 works in a thread formed in the flat portion of the clampe,
and after the tyre has been inflated, the screw e³ has simply to be turned a few times
to prevent any escape of the air or gas.
In the example represented in the drawing, after jointing up the tube b in the
form of a ring and partially inflating it, I bind it round the entire circumference in

page_text: a spiral form with a coating f of strip leather, strip india rubber webbing, or other
suitable material, but preferably strong webbing or canvas. I then put it into the
felloe and I again bind it and the felloe in a spiral form around the entire circum-
ference with a coating g of strip leather, strip india-rubber webbing, or other suitable
material.
Without limiting the expansion of the rubber tube 6 by some means,
the necessary
compression of the air or gas cannot be obtained, and by binding it spirally according
to my invention, it can be done by any unskilled person and cheaper than by the
present known means.
If desired the inner spiral binding ƒ may be dispensed with, it will be understood
that cement will be applied between the spiral bindings or coatings f. g. and the
parts with which they come in contact.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is―
1. An inflated wheel tyre consisting of an inner india rubber tube, a spiral
binding or coating around the same, and another spiral binding or coating around
the latter and the felloe, substantially as herein shown and described.
2. An inflated wheel tyre consisting of an inner india rubber tube and a spiral
binding or coating around the same and the felloe, substantially as herein shown
and described.
3. An inflated tyre constructed as referred to in Claims 1 and 2 and provided
with an inflation socket or nozzle constructed and fixed thereto as herein described.
4. The combination with inflated tyres, of an injection socket or nozzle con-
structed and fixed thereto as described, an india rubber tube on such socket or
nozzle, and a screw clamp on such tube, substantially as herein shown and described
and for the purpose stated.
5. The improvements in inflated tyres for the wheels of velocipedes and other
carriages substantially as herein shown and described.
