I ALFRED PARR, of 130 Neate Street, Camberwell, in the County of London,
Labourer, 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 that class of pneumatic tyres, the outer coverings of
which are fastened to the rims by means of wires passing through pockets or the
like in the edges of the said outer coverings, and has for its object to prevent the
tyre coming off the rim of the wheel immediately the air bag collapses on account
of a puncture or from other cause.
According to this invention I employ two wires, running round each side of the
tyre, between layers of canvas.
The ends of one of the wires on each side are
bent, and have studs attached to them. The wires cross each other and the studs
fit into key-hole slots in the rims. The other wire on each side is left without its
ends being connected.
And in order that my invention may be clearly understood I will proceed to
describe the same with reference to the drawing accompanying this Specification,
in which
Fig. 1 shews a sectional elevation of a portion of a pneumatic tyre, made
according to my invention-attached to the rim :
Fig. 2 is an elevation of a portion of the rim and tyre, shewing the wires out of
position, and the outer covering partly removed in order to reach the air bag.
Fig. 3 shews the position the wires would assume when connected to the rim.
The same letters of reference are employed to denote the same parts in all the
views.
a shews the rim, b key-hole slots, c outer covering d wires, provided with studs e,
f the free or additional wires, g is the air bag.
The method of fixing the tyre to the rim is as follows. The wires d, in the
edges of the outer covering c being threaded through the pockets to contain them
in the ordinary way, the ends are crossed as shewn at Fig. 3, and the studs e are
passed through the key hole slots 6 in the rim a. The additional wires are also

page_text: threaded through pockets at the edges of the outer covering, but the ends of the
wires are not connected. The edges of the outer covering are then pushed down
under the rim in the ordinary way and the tyre inflated.
Access can be obtained to the air bag when required by deflating the tyre if
necessary, slipping the studs b from the holes e and drawing back the outer
-covering so that the air bag may be reached.
It will be observed that if the air bag collapses, by reason of a puncture or
from any other cause, the additional wire f will have the effect of holding the
tyre temporarily upon the rim a, and preventing the same from flying off, should
the studs e slip out of the key hole slots e.
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. The improvements in pneumatic tyres, substantially as and for the purposes
set forth.
2. In pneumatic tyres, such as those described, the additional wires for the
purpose set forth.
3. In pneumatic tyres, such as those described, the combination of the wires d,
studs e, key hole slots 6 and additional wires ƒ, all substantially as and for the
purposes set forth.
