COMPLETE SPECIFICATION.
Improvements in Elastic Tyres for Vehicle Wheels.
We A. HUTCHINSON & Co. of 1 Rue d'Hauteville, Paris, in the Republic of
France, India Rubber Manufacturers, 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 relates to an improvement in elastic tyres for vehicle wheels, and
it consists essentially of an improved method of securing and fixing the tyre to
the wheel rim.
In order that our invention may be fully understood we will particularly describe
it making reference to the accompanying drawing, in which
Figure 1 is a broken view in side elevation and Figure 2 is a view in cross
section on line "x
k """ Figure 1 of our improved tyre.
Figures 3 & 4 are similar views of a modification thereof and
Figure 5 is a view in cross section of another form our invention may assume.
Throughout the views similar parts are marked with like letters of reference.
A denotes the rim or felloe of the wheel to which the elastic tyre D is fixed by
means of clamping rings B, B, secured to the sides of the rim or felloe A by
means of screws or bolts C, C, etc.
The outer edges of the rings B, B, are bent inwards as shown by Figures 2, 4
and 5 so that they overhang towards the centre of the rim or felloe, and clamp
between them the elastic tyre D which is preferably made of rubber but may also
be made of any other suitable flexible material either in combination with, or
without rubber. The base of the elastic tyre is preferably made of harder
material than the top part as shown by Figure 5 in which the base of the rubber
tyre is made of hard rubber or vulcanite. The clamping rings B, B, are preferably
let into the sides of the rim or felloe A so that they lie flush therewith and they
may each have a small flange "b" as shown by Figure 5.
As a modification the rim or felloe A may be fitted with a metal tyre E on
which the elastic tyre D rests as shown by Figures 3 and 4, the said metal tyre
being fixed to the rim or felloe A by screws or bolts F, F, etc. in the ordinary
manner.
We wish it to be particularly understood that we do not limit ourselves to the
precise details of construction hereinbefore described and illustrated by the
accompanying drawing but that we hold ourselves at liberty to make such changes
and alterations as fairly fall within the spirit and scope of our invention.
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. The improvements in elastic tyres for vehicle wheels, as hereinbefore
described and illustrated by the accompanying drawing.

page_text: 2. In a vehicle wheel, the combination with the rim or felloe A, of the two
clamping rings B, B, of the screws or bolts C, C, etc., and of the elastic tyre D,
all combined, arranged and operating, as and for the purpose set forth.
3. In a vehicle wheel, the combination of the rim or felloe A, of the two clamping
rings B, B, of the screws or bolts C, C, etc., of the elastic tyre D, of the metallic
tyre E, and of the screws or bolts F, F, etc., all combined, arranged and operating
as and for the purpose set forth.
