An Improved Shielding Device for Preventing Puncture in Pneumatic
Tyres and the like.
I, RICHARD BROGDEN BAINES, of 2, Elizabeth Street, Liverpool, in the County of
Lancaster, Estate Agent, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object a circular shield having approximately a semi-
circular cross section and formed of rolled steel to be placed over the pneumatic
tyre covering the same. In order to enable this shield to run without skidding
on the road about three-eights of an inch on each side of the centre line I place
projecting rib, the three-quarter inch in space or thereabouts between being the
centre of the tread of the wheel.

An Improved Shielding Device for Preventing Puncture in Pneumatic
Tyres and the like.
I, RICHARD BROGDEN BAINES, of 2, Elizabeth Street, Liverpool, in the County of
Lancaster, Estate Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
1
This invention has for its object an improved shielding device for preventing
puncture in pneumatic tyres and the like.
It will be understood from the following description, reference being had to
the accompanying drawing, in which,
Figure 1 shows a segment of my shielding device that goes round the outside
periphery of the tyre;
Figure 2, a cross section of same.
It comprises a circumferential shield A having approximately a semicircular
cross section and formed of rolled steel, to be placed over the tread of the pneu-
matic tyre circumferentially so as to cover and protect the same. In order to
enable this shield to run without skidding on the road, about three-eighths of an
inch on each side of the centre line I place projecting ribs B, a three-quarters of
an inch space between being the centre of the tread of the wheel.

page_text: To apply this shield to pneumatic tyres, all that is necessary is to place it round
the outside periphery of the tyre, then inflate the latter and the shield will be held
in place by the inflation so that it will not come off. An appliance of this kind will
be found to be a very useful auxiliary for pneumatic tyres, as it will prevent pune-
ture from thorns and other sharp articles met with on the surface of the road, and
can be applied to any pneumatic tyre.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
1. A shielding device for preventing puncture in pneumatic tyres and the like,
comprising a circumferential shield adapted to be placed round the outside periphery
of the tyre so as to cover and protect the same, substantially as described.
2. A shielding device for preventing punctures in pneumatic tyres and the
like, comprising a circumferential shield adapted to go round the outside periphery
of the tyre, and having projecting ribs B on each side of the centre line, substan-
tially as and for the purpose described.
