Improvements in Protecting Covers, chiefly designed for Pneumatic
Tyres.
I, FRÉDÉRIC CASASSA, of 10 Rue Jacquart, Pantin (Seine), in the Republic of
France, Rubber Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved protecting cover designed particularly for
covering the pneumatic tyres of velocipedes and other vehicles.
This improved protecting cover consists in principle of a protecting tube constituted
by very thin and very flexible strips of steel interwoven either by mechanical means
or by hand, this protecting tube being furnished upon its internal and external faces
with a double covering of rubber and cloth; the tube thus obtained is then beaten out
to the required form so as to present a double thickness.
In order that my invention may be properly understood I have shown the principle
of the same in the accompanying drawing, by way of example only, the said drawing
representing the thicknesses of the several constitutive parts to an enlarged scale.
Figure 1 shows an elevation of a portion of the metallic protector.
Figure 2 is a transverse section.
Figure 3 is a transverse section showing the constitution of the protecting cover
before the enchasing of the same.
Figure 4 is a transverse section of the protecting cover after the enchasing of the
same.
In these several figures the same letters of reference designate the same parts.
The improved protecting cover consists in principle of a protecting tube a consti-
tuted by a certain number of very thin and very flexible metallic strips interwoven
either by mechanical means or by hand so as to form a cylindrical tube; these strips
are preferably of steel, but I may employ any other metal or any other suitable
material.
The tube a is protected upon its internal and external faces by a covering b of
rubber or any other agglutinant material covered in turn by an envelope c of cloth.
This double covering has for its object to maintain the protector a in the form
which is afterwards given to it by beating out and to protect it against oxidation.
In order to construct this protecting cover I commence by placing upon a mandril
the interior cloth tube c which is covered with a rubber tube b; upon this double
covering thus constituted I form the protector a and cover the latter with a layer b of
rubber which is then covered with a cloth tube c.
The cylindrical tube thus constituted (Figure 3) is then beaten out to the required
form so as to present a semicircular section (Figure 4), the two thicknesses of the

page_text: tube being applied one against the other and thus presenting a double security against
puncture.
The two extremities of this protecting cover are then united with each other so as to
constitute a closed ring, this mode of union may be effected in any suitable manner
either by sewing, or by hooks so as to facilitate the mounting and dismounting.
The protecting cover thus constituted is applied to the air chamber between the
latter and the cover of the pneumatic tyre and will protect it against punctures by
nails, against tearing by sharp articles which may be encountered on the roads;
moreover it opposes the bursting of the air chamber whether produced by an excess of
pressure during the inflation or by an increase in volume due to the elevation of
temperature.
The protecting cover, by reason of its special constitution, may receive any other
application.
It may serve to protect against perforations, and to prevent bursting, of receptacles
of elastic or unelastic material containing air or gas under pressure.
It may also be applied to the manufacture of cuirasses designed to protect persons
against bullets or any arm.
It will be understood that I may apply several thicknesses of metallic protectors
of rubber and cloth so as to increase the strength of my system of protecting cover,
and I may modify the details of construction according to the several applications.

COMPLETE SPECIFICATION.
Improvements in Protecting Covers, chiefly designed for Pneumatic
Tyres.
I, FREDERIC CASASSA, of 10 Rue Jacquart, Pantin (Seine), in the Republic of
France, Rubber Manufacturer, 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 an improved protecting cover designed particularly for
covering the pneumatic tyres of velocipedes and other vehicles.
This improved protecting cover consists in principle of a protecting tube constituted
by very thin and very flexible strips of steel interwoven either by mechanical means
or by hand, this protecting tube being furnished upon its internal and external faces
with a double covering of rubber and cloth; the tube thus obtained is then beaten out
to the required form so as to present a double thickness.
In order that my invention may be properly understood I have shown the principle
of the same by way of example in the drawing left with my Provisional Specification,
the said drawing representing the thicknesses of the several constitutive parts to an
enlarged scale.
Figure 1 shows an elevation of a portion of the metallic protector.
Figure 2 is a transverse section.
Figure 3 is a transverse section showing the constitution of the protecting cover
before the beating out of the same.
Figure 4 is a transverse section of the protecting cover after the enchasing of the
same.
In these several figures the same letters of reference designate the same parts.
The improved protecting cover consists in principle of a protecting tube a consti-
tuted by a certain number of very thin and very flexible metallic strips interwoven

page_text: either by mechanical means or by hand so as to form a cylindrical tube; these strips
are preferably of steel, but I may employ any other metal or any other suitable
material.
This tube a is protected upon its internal and external faces by a covering b of
rubber or any other agglutinant material covered in turn by an envelope c of cloth.
This double covering has for its object to maintain the protector a in the form
which is afterwards given to it by beating out, and to protect it against oxidation.
In order to construct this protecting cover I commence by placing upon a mandril

tube being applied one against the other and thus presenting a double security against
puncture.
The two extremities of this protecting cover are then united with each other so as

either by sewing, or by hooks so as to facilitate the mounting and dismounting.
The protecting cover thus constituted is applied to the air chamber between the

moreover it opposes the bursting of the air chamber whether produced by an excess

It may serve to protect against perforations, and to prevent bursting, of receptacles
of elastic or unelastic material containing air or gas under pressure.
It may also be applied to the manufacture of cuirasses designed to protect persons

It will be understood that I may apply several thicknesses of metallic protectors of
rubber and cloth so as to increase the strength of my system of protecting cover, and
I may modify the details of construction according to the several applications.
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 1
claim is :-
First. The protecting cover constituted in principle by a metallic protector formed
by the interweaving of a certain number of flexible and very thin strips, this protector
being protected upon its two faces by a double cover of rubber and cloth.
Second. The improved protecting cover constituted in principle by a metallic
protector formed of a certain number of flexible and very thin strips interwoven in
the form of a tube, this protector protected on its two faces by a double covering of
rubber and cloth being then heaten out to the desired form so as to present a double
thickness substantially as herein before described with reference to the drawing and for
the purposes specified.
