PROVISIONAL SPECIFICATION.
Improvements in or relating to Pneumatic Tyres.
I, SYDNEY LEE, of 9 Furnival Street, in the County of Middlesex, Managing
Director of The Puncture-proof Pneumatic Tyre Co. Ltd., do hereby declare the
nature of this invention to be as follows:-
This invention relates to pneumatic tyres and devices for preventing puncturing
and slipping and may be carried out as follows:
In the case of a puncture proof band to prevent puncture of the air-tube I make
a cover of canvas or other suitable material preferably impregnated with rubber or
having a glazed surface to prevent friction, having at its edges elastic threads,
cords or enlargements. This cover may be conveniently placed outside the air-tube
and between it and the ordinary outer tyre cover; it may have the puncture proof
band attached to it or it may itself be the puncture proof band. The prevention
of puncture may be obtained by any suitable means such for example as the
Williams wool and resin bands, the Parkin & Wright steel plate bands or
continuous plate bands or the like. The above described cover is placed upon the
air tube its elastic edges being capable of being slipped over and between the edges
of the rim of the wheel and then drawing the cover down on to the rim and
preventing it from slipping out of place, the tyre cover proper, which may be of
any well-known description say a cover with wire hoops in the edges protecting the
puncture proof device and retaining it upon the rim.
When this invention is to be used for non-slipping purposes it may be placed
outside the tyre cover proper, say of the description above mentioned, the elastic
edges being pushed down between the rim and the edges of the tyre cover proper
so that the elastic beads lie inside the wires of the cover and are thus prevented
I may
from drawing out when the tyre is inflated. For non-slipping purposes
provide this cover with suitable means to prevent the tyre from slipping on the
road. By this means it will be seen that puncture proof bands or non-slipping
covers instead of being solutioned to the cover as usual may be easily attached to
or detached from pneumatic tyres by the rider himself.

I, SYDNEY LEE, of 9 Furnival Street, in the County of Middlesex, Managing
Director of The Puncture-proof Pneumatic Tyre Company Limited, 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 pneumatic tyres and devices for preventing puncturing

page_text: and slipping and will be best understood by reference to the accompanying
drawings in which
Figures 1 and 2 are views showing a portion of one form of tyre constructed
according to my present invention, Figure 1 being a perspective view representing
the tyre as partly open, ready to receive the air-tube which is not shown in this
figure, and Figure 2 a perspective view of the tyre as complete, and
Figures 3, 4 and 5 are views showing the employment of special forms of
puncture-proof bands in accordance with my invention.
Figure 3 is a transverse section showing the employment of one form of puncture-
proof band.
Figure 4a perspective view showing the employment of another form of
puncture-proof band, and
Figure 5 a transverse section showing the employment of a continuous metal
band.
Figure 6 is a transverse section showing the application of my invention for non-
slipping purposes.
Like letters indicate like parts throughout the drawings.
Hitherto puncture-proof bands have been made of sufficient width only to protect
the tread portion of the air-tube A about as shown in Figure 5, but by this
invention make a cover B of canvas or other suitable material preferably
impregnated with rubber or having a glazed surface to prevent friction and having
at its edges elastic threads or cords B', which almost completely surrounds the
air-tube. This cover is the puncture-proof band and may be conveniently
placed outside the air-tube A, and between it and the ordinary outer tyre-
cover C.
The prevention of puncture may be obtained by any suitable and well-known
means, such for example, as illustrated in Figure 3, a wool or wool and resin
band D, Lee's overlapping metal plate band E, as shown in Figure 4, or a
continuous metal or equivalent band F, as indicated in Figure 5, the devices D E
and F, being applied or secured to or incorporated in the cover B by any of the
means hitherto adopted for the purpose.
The puncture-proof cover B B' is placed upon the air-tube A, its elastic edges B¹
being slipped over and between the edges G₁ of the wheel rim G, and then drawing
the cover B down on to the rim G and preventing it from slipping out of place, thus
protecting the air-tube not only from puncture but from frictional contact with the
outer cover which often wears out the air-tube. The tyre cover C may be of any
well-known description, say as represented in the drawings, a cover with wire-
hoops C¹ in the edges; but the method of fastening the tyre-cover to the rim does
not form part of the present invention.
When the before-described band B B' as indicated in Figure 6, is to be used for
non-slipping purposes, it may be placed outside the tyre-cover C, and if the cover
be constructed with wire hoops C¹ as before described the elastic edges B¹ will be
pushed between the rim G and the wired edges of C, so that the elastic beads lie
inside the wires C¹ of the cover C and are thus prevented from drawing out when
the tyre is inflated. For non-slipping purposes I may provide the cover or
band B B¹ with any suitable means to prevent the tyre from slipping
on the road.
By this means it will be seen that puncture-proof bands or non-slipping covers
instead of being solutioned to the cover C as usual may be easily attached to or
detached from pneumatic tyres by the rider.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is ;-
1. Retaining the puncture-proof band of a pneumatic tyre in position by elastic
threads or cords at its edges.
2. Retaining the non-slipping band or combined non-slipping and puncture-proof
band of a pneumatic tyre in position by elastic threads or cords at its edges.

page_text: 3. The combination with a puncture-proof or non-slipping band or a combined
puncture-proof and non-slipping band for a pneumatic tyre of elastic threads or
cords at its edges.
4. In a pneumatic tyre the combination with an air-tube or with an air-tube and
cover of a puncture-proof or non-slipping band or a combined puncture-proof and
non-slipping band having elastic threads or cords at its edges.
5. In a pneumatic tyre the combination with an air-tube and cover of a non-
slipping band having elastic threads or cords at its edges overlapping the edges of
the cover and fixed by them substantially as described and illustrated in Figure 6
of the accompanying drawings.
6. The combination with an overlapping metal plate puncture-proof band such
as E B for a pneumatic tyre of elastic threads or cords such as B¹ at its edges
substantially as described and illustrated in Figure 4 of the accompanying
drawings.
