PROVISIONAL SPECIFICATION.
A Covering or Sheath intended for the Protection of the Pneumatic
Tyres of Velocipedes.
I, CHARLES KLEINERMANN, of 45 Rue du Pot d'or, Liège, in the Kingdom of
Belgium, Student, do hereby declare the nature of this invention to be as follows:-
This invention relates to a covering or sheath intended for the protection of the
pneumatic tyres of velocipedes. The frequent damages suffered by the india rubber
pneumatic tyres of velocipedes of all kinds render these latter apparatuses very
unsafe and in fact but little practical. An encounter with any object somewhat
sharp or pointed puts the pneumatic tyre and consequently the velocipede out of
order and unfit for use.
The object of this invention is to remedy this serious defect by providing the
pneumatic tyre with a protective covering or sheath.
Referring to the accompanying drawing-
Figure is part of a wheel provided with my covering and represented partly in
side elevation and partly in section;
Figure 2 is a view of the internal periphery of the wheel provided with the
covering or sheath ;
Figure 3 is a section at A. B, Fig. 1:
Figure 4 exterior view of the covering or sheath spread out, and
Figure 5 a section through the sheath at C, D, Fig. 4.
The sheath or covering, Figs. 4 and 5, is composed of one, or preferably of two
strips or bands, a and b, of well scoured leather, of different breadths and the
thicknesses of which may also vary. The ends of each of these strips are joined
together so as to form endless bands which, superposed and united by sewing, by
riveting, by glucing or in any suitable manner present an equal diameter, preferably
slightly less than the greatest diameter of the pneumatic tyre.
The inner band is preferably made of thicker leather than the outer band a;
its width is much less than that of this latter and it is such that it corresponds
approximately to the crushing or flattening of the pneumatic tyre under the weight
of the rider.
The inner band will preferably have its two longitudinal edges (turned towards
the outer band a) cut to a bevel, Fig. 5. The joining of the two bands a and b by
sewing is done so that the stitches do not pass through the thickness of the outer
band a.
This outer band a is of such breadth that it may partially or totally surround
the pneumatic tyre c, that is to say the felloe of the wheel of the velocipede,
Figs. 1 and 2. In order that the sheath or covering thus constructed may, as far
as possible, fit upon the felloe of the wheel without. folds or creases, there are made
along the two sides of the outer band cuts or notches d, of a triangular shape and
of sufficient breadth the top of these triangles d may terminate in a circular notch
or groove, Figs. 1, 2 and 4. The two longitudinal sides of the sheath or covering
are united or brought towards each other preferably on the inner periphery of the
wheel, Figs. 1, 2 and 3, by means of one or of two laces or small cords i passed
alternately into hooks o (such as are used in boots and shoes) fixed along the sides
of the sheath instead of hooks eyelet holes or any other fastening arrangement
may be used.
Whatever may be the method and the point of junction or bringing
together of the lateral sides of the sheath or covering, its double thickness of
leather must always form the outer periphery of the wheel.
To place the sheath or covering on the pneumatic tyre, the air is let out of the
tyre, the sheath is placed on the wheel without lacing, a little air is then pumped

page_text: into the pneumatic tyre so that the sheath is kept in place by contact therewith.
Then the sheath is fixed as aforesaid by the aid of the laces, then the necessary
quantity of air is compressed into the tyre so that the sheath is well stretched on
the wheel..

A Covering or Sheath intended for the Protection of the Pneumatic
Tyres of Velocipedes..
I CHARLES KLEINERMANN of 45 Rue du Pot d'or, Liège, in the Kingdom of
Belgium, Student, 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 relates to a covering or sheath intended for the protection of the
pneumatic tyres of velocipedes. The frequent damages suffered by the india
ŕubber pneumatic tyres of velocipedes of all kinds render these latter apparatuses
very unsafe and in fact but little practical. An encounter with any object somewhat
sharp or pointed puts the pneumatic tyre and consequently the velocipede out of
order and unfit for use.
The object of this invention is to remedy this serious defect by providing the
pneumatic tyre with a protective covering or sheath.
Referring to the drawing left with the Provisional Specification: T
Figure is part of a wheel provided with my covering and represented partly in
side view and partly in sections;
Figure 2 is a view of the internal periphery of the wheel provided with the
covering or sheath;
sheath spread out, and
D Figure 4.
Figure 3 is a section at A. B, Figure 1;
Figure 4 exterior view of the covering or
Figure 5 a section through the sheath at
The sheath or covering. Figures 4 and 5, is composed of one, or preferably of
two strips or bands, a and b, of well scoured leather of different breadths and the
thicknesses of which may also vary. The ends of each of these strips are joined
together so as to form endless bands which superposed and, united by sewing, by
riveting, by glueing or in any suitable manner present an equal diameter, preferably
slightly less than the greatest diameter of the pneumatic tyre.
The inner band b is preferably made of thicker leather than the outer band a;
its width is much less than that of this latter and it is such that it corresponds
approximately to the crushing or flattening of the pneumatic. tyre under the weight
of the rider. The inner band will preferably have its two longitudinal edges
(turned towards the outer band a) cut to a bevel, Figure 5. The joining of the
two bands a and b by sewing is done so that the stitches do not pass, through the
thickness of the outer band a.
The outer band, a is of such breadth that it may partially or totally surround the
pneumatic tyre c, that is to say the felloe of the wheel of the velocipede Figures 1.
and 2.
In order that the sheath or covering thus constructed may, as far as
possible, fit upon the felloe. of the wheel, without folds or, creases, there are made
along the two sides of the outer band cuts or notches d, of a triangular shape and of
sufficient breadth; the top of these triangles d' may terminate with a circular notch
or groove, Figures 1, 2 and .4. The two longitudinal sides of the sheath or
covering are united or brought towards each other preferably on the inner periphery
of the wheel, Figures 1, 2 and 3, by means of one or of two laces or small cords;
passed alternately into hooks o (such as are used in boots and shoes) fixed along

page_text: the sides of the sheath instead of hooks, eyelet-holes or any other fastening
arrangement may be used. Whatever may be the method and the point of junction
or bringing together of the lateral sides of the sheath or covering, its double.
thickness of leather must always form the outer periphery of the wheel.
To place the sheath or covering on the pneumatic tyre, the air is let out of the
tyre, the sheath is placed on the wheel without lacing, a little air is then pumped
into the pneumatic tyre so that the sheath is kept in place by contact therewith.
When the sheath is fixed as aforesaid, by the aid of the laces then the necessary
quantity of air is compressed into the tyre so that the sheath is well stretched on.
the wheel.
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 :-
:-
A protective covering or sheath for the india rubber and other tyres of velocipedes,.
composed of one or of several endless strips or bands of leather of such breadth that
the outer band totally or partially envelopes the pneumatic tyre, while (when using
several superposed bands) the inner band is only of a breadth corresponding
approximately to the crushing or flattening of the tyre under the weight of the
velocipedist, the outer band being provided on its lateral sides with triangular cuts
sufficiently broad and deep to permit its application on the pneumatic tyre without
foldings and, further, with hooks which permits bringing together or reuniting the.
lateral sides by the aid of laces.
