Improvements in Elastic Tyres for Velocipedes and other
Vehicles.
I, THÉODORE STERNÉ, of 20 Rue St. Lazare, Paris, in the Republic of France,
Engineer, 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 :--
The invention relates to that class of tyre for which I obtained Letters Patent
No. 24,091 dated May 16, 1893, the object of the present invention being to render
the tyre more resilient and to facilitate the manufacture of the same.
The invention is illustrated in the accompanying drawings, in which :-
Fig. 1 is a plan of part of a strip or width of notched sheet metal or other
suitable material such as I employ in the construction of my improved tyre.
Fig. 2 is a section of a tyre made from the width or strip of sheet metal or other
suitable material shown at Fig. 1 attached to a rim.
Fig. 3 is another form of tyre capable of being made in the same manner.
Fig. 4 is an inside view of the tyre shown at Fig. 3 separately, and
Fig. 5 is a side view of the same.
In carrying my invention into effect I take a sheet of any suitable material
sufficiently wide to roll into the form of tyre I wish to construct, and I cut out
notches of any desired shape along both edges, leaving tongues a and a running
surface a'. This strip or width of sheet metal or other material may be rolled or
formed thicker at that part, a', which is to form the running surface of the tyre.
This strip or width of sheet metal or other material is then rolled or formed into
the shape shown at Fig. 2, or into the shape shown in Fig. 3, and in some cases
I may rivet, braze, solder, or otherwise connect the overlapping edges, after
which the tyre is bent into a circle and the ends connected in any convenient
manner.
The portions of metal or other material removed from the blanks shown in Fig. 1
enable the tyre more readily to be bent into a circular form, whilst leaving a good
continuous running surface a¹.
The tyre above described will preferably be provided with a covering c of any
suitable material, such as india-rubber or leather, to protect the tyre and to
prevent the entry of dust, mud, stones, or other matter which would not be
desirable. If desired the covering c may be made thicker on the running
surface.
A tyre as above described may be used in lieu of the inner or air tube in some
forms of pneumatic tyres now in use and thus obviate the necessity of inflating the
same.
The tyre may be connected to the rim b by means of a wire or cord d as shown
in the drawings, or in other convenient manner.
The covering may be cemented to the tyre, or it may be attached thereto, or to
the rim, in any convenient manner; or the tyre may be attached to the rim by
means of the outer cover.
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. A tyre for velocipedes and other vehicles made from a strip, width or blank

page_text: of sheet metal or other material having portions of the same removed along its
edges, substantially as herein shown and described.
2. A tyre for velocipedes and other vehicles made from a strip, width or blank
of sheet metal or other material rolled or formed to such a section that the running
surface is thicker than the edges thereof and having portions of the material
removed along its edges, substantially as herein shown and described.
3. A tyre for velocipedes and other vehicles made from a strip, width or blank
of sheet metal or other material of thicker section on the running surface than
at the edges and having portions of the metal removed along its edges and
provided with a covering of any suitable material, substantially as herein
described.
4. In tyres for velocipedes and other vehicles, the use of a tyre substantially as
herein shown and described in lieu of the inner or air tube now employed in the
interior of some forms of pneumatic tyres.
Dated this on day or
ADTI 1897.
