PROVISIONAL SPECIFICATION.
Improvements in and relating to Means for Securing Elastic Tyres
in Place.
1, CARL BENZ of Mannheim in the Grand-Duchy of Baden, German Empire,
Manufacturer do hereby declare the nature of this invention to be as follows:→
This invention refers to wheels of that kind, in which the rigid tyre connecting
the felloes is furnished with an elastic covering, or special elastic tyre respectively,
consisting of india rubber or the like. My improvements in wheels of said kind
relate to the means for securing said elastic covering or tyre in place; and my
invention proper consists in providing the said elastic tyre at its inner surface or
side with a hard inlay adapted to receive fastening-screws.
I have represented one mode of construction in the accompanying drawing, in
which
Figure 1 is a side-view of a part of a wheel having its outer or elastic tyre
fastened according to my invention, and
Figure 2 is a section through the two tyres drawn on a larger scale.
The elastic outer tyre A consists of india-rubber, and is at its inuer surface
furnished with the hard inlay or inlays a, that may consist of any material
allowing of being provided with screw-threaded holes, and may be in the shape of
single or separate pieces forming each a sort of female screw, or of ledges or bar
curved according to the curvature of the rigid -inner tyre B.
The latter may be of any desired or suitable construction; I prefer to use tyres
with flanges or projections (such as 6 b) bent against each other so as to grasp the
inner portion of the elastic tyre A between them.
Said tyre A is fixed in place by drawing screws c from below the tyre B up into
the inlays a; said screws may, as a matter of course, themselves be secured in place
by any suitable means.

I, CARL BENZ, of Mannheim in the Grand-Duchy of Baden, German Empire,
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:-
This invention refers to wheels of that kind, in which the rigid tyre connecting
the felloes is furnished with an elastic covering or special elastic tyre respectively,
consisting of india rubber or the like. My improvements in wheels of said kind
relate to the means for securing said elastic covering or tyre in place; and my
[Price 81

page_text: invention proper consists in providing the said elastic tyre at its inner surface or
side with a hard inlay adapted to receive fastening-screws.
I have represented one mode of construction in the drawing sent in with
Provisional Application, in which:
Figure 1 is a side-view of a part of a wheel having its outer or elastic tyre
fastened according to my invention, and
Figure 2 is a section through the two tyres drawn on a larger scale.
The elastic outer tyre A consists of india-rubber, and is at its inner surface
furnished with the hard inlay or inlays a, that may consist of any material
allowing of being provided with screw-threaded holes, and may be in the shape of
single or separate pieces forming each a sort of female screw, or of ledges or bars
curved according to the curvature of the rigid inner tyre B.
The latter may be of any desired or suitable construction; I prefer to use tyres
with flanges or projections (such as bb) bent against each other so as to grasp the
inner portion of the elastic tyre A between them.
Said tyre A is fixed in place by drawing screws c from below the tyre B up into
the inlays a; said screws may, as a matter of course, themselves be secured in
place by any suitable means.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a wheel, the combination with the rigid tyre of the same, of an elastic
tyre having at its inner surface a hard inlay or inlays adapted to receive means for
fastening said elastic tyre to said rigid one, substantially as described.
2. In a wheel, the combination with the rigid tyre of the same, of an elastic
tyre having at its inner surface a hard inlay or inlays adapted to receive screws for
fastening said elastic tyre to said rigid one; said screws being passed into said
inlay or inlays from below the said rigid tyre, substantially as described.
3. In a wheel, the combination with a rigid flat tyre B having inwardly bent
flanges b, of a correspondingly shaped elastic tyre A having at its inner surface a
hard inlay or inlays a adapted to receive screws c for fastening said elastic tyre to
said rigid one; said screws being passed into said inlay or inlays from below the
said rigid tyre, substantially as described.
