Improvements in and relating to Tyres.
We EDMOND GARNIER of 2 Mill Street Conduit Street in the County of
Middlesex Cycle Manufacturer, and, THOMAS BURGESS of 12 Fouberts Place
Regent Street in the County of Middlesex, Surgeon Dentist, do hereby declare
the nature of this invention to be as follows:-
Our invention consists of improvements in and relating to tyres. The tyres are
made in two sections, an upper and lower. The upper section fixes in the rim and
is secured by cement or other means. The rim and upper section are shaped, so
that when in combination they form a chamber. The top of the sides of the lower
section rest against the lower part of the rim turned from the sides of the upper
section. The centre of this lower section is raised and shaped to receive when
under pressure a projecting piece from the upper section, when these two parts are
in contact, a chamber to the right and left is formed. The lower section is secured
to the rim by a canvas band, lacing, or other means.

COMPLETE SPECIFICATION.
Improvements in and relating to Tyres.
We, EDMOND GARNIER of 2 Mill Street, Conduit Street, in the County of
Middlesex Cycle Manufacturer, and THOMAS BURGESS of 12 Foubert's Place
Regent Street in the County of Middlesex Surgeon Dentist 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 :-
Our invention consists in improvements in and relating to tyres. The tyres are
made in four parts or sections viz. an upper and a lower and two intermediate. The
upper intermediate section fixes into the rim by being sprung in. The rim and the
said upper section are shaped so that, when in combination, they form an air
chamber. The underside of the said intermediate section is also shaped or hollowed.
The central portion of the upper side of the lower intermediate section is raised and
shaped to coincide with the said hollow in the upper section. When these two
parts or sections are brought into contact a chamber to the right and left is formed.
The said lower intermediate section is fixed to the lower section or outer cover
which is shaped, the combination of these two sections form another or fourth
chamber. The whole arrangement constitutes a complete tyre by being secured
together by a canvas band, lacing or other means.
In order that our said invention may be more readily understood and carried
into effect we will proceed to describe the same by the accompanying drawings.
A. Fig. 1 is a transverse section of the rim which may be either hollow or solid.
B. Fig. 2 is the upper section which is sprung in and held in position in the rim
by its own elasticity and without the application of any adhesive substance, as
shewn in position by the dotted lines on Fig. 1.
C. Fig. 3 is the ring which is adapted and attached by cementing glueing or
other means to the outer cover D Fig. 4, and as shewn in position by dotted lines
on Fig. 4.
D. Fig. 4 is the said outer cover or lowermost section which is fastened to the
rim A by a canvas band G or by cementing glueing lacing or other means after the
[Price 8d.1

page_text: ring or lower intermediate section C. Fig. 3 takes its place or position in the lower
hollow E of B. Fig. 2.
Fig. 5 is a transverse section of the complete tyre when the respective parts are
brought together in the positions intended."
F. F. F. F. are hollow spaces or chambers between the respective component
parts of the tyre giving the whole construction greater elasticity.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what.we
claim is :-
1. A tyre made in four parts or sections.
2. A tyre of which one portion is a specially constructed and shaped rim into
which is sprung an upper section or portion held in place or position by its own
elasticity, against which presses a lower section or portion attached to the lower-
most section or outer cover and acting as a spring-the whole being secured to the
rim and forming together a complete tyre as before described.
3. That by the particular arrangement and combination of the several parts
certain air chambers or spaces are formed.
4. The whole combination as before described whilst having all the advantages
of a pneumatic tyre has not its disadvantages.
