An Improved Protector Tyre for Pneumatio and other Elastic
Wheel Tyres.
I, FRIEDRICH HERMANN FISCHER, of Cölln on the Elbe, Germany, House
Proprietor, 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 tyre which is designed mainly for the protection of
the pneumatic tyres of cycles but which may also be applied to other hollow, and
also to solid india rubber or other elastic wheel tyres. The object of the invention
is to protect the main elastic wheel tyre from sharp stones or other objects lying
upon the road.
In the accompanying drawing which illustrates the invention,
Fig. 1 is a perspective cross sectional view of a portion of a pneumatic tyre with
the protector tyre of this invention applied thereto.
Figs. 2 and 3 are cross sectional views of a pneumatic tyre shewing other forms
of the protector tyre applied thereto.
s is the protector tyre made with a completely closed surface and so wide and so
curved in cross section that it embraces the main elastic tyre approximately
to the extent of one-third of its circumference so as to be capable of protecting
said main tyre from sharp objects met with in travelling upon the road. The
protector tyre is preferably made of spring sheet steel but other sheet metal or
other suitable material may be employed which is capable of affording sufficient
resistance to wear and injury.
The protector tyres is attached to the main tyre r by placing it round the latter'
when in the uninflated state and then operating the inflation, but in the case of
hollow india rubber so-called cushion tyres, or of solid india rubber tyres the
attachment of the protector tyre is effected by simply forcing or springing it
thereon. The edges of the protector tyre are curved outwards or somewhat bent
round away from the main tyre in order that this may not be cut into when the
cycle is being ridden. The protector tyre may also be provided with ribs to
prevent slipping on paved or uneven roads and its cross sectional form may be so
varied as to be suitable for application to different forms of tyres as they come
into commercial use at different times, different forins forms being shewn in the
different figures of the drawing. fis the felloe of the wheel.
It will be obvious that by means of a tyre protector of the kind described, the
covering r of the air tuber may be made of a lighter and cheaper material, as a
great durability of the same is not of so much importance as is the case without
the protector.
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 protector tyres having a completely closed surface, for attachment to pneu-
matic and other hollow and also to solid india rubber or other elastic wheel tyres.
