PROVISIONAL SPECIFICATION.
Improvements in Wheel Tyres for Velocipedes and other Vehicles.
ROBERT ABRAM LEE, 203 Shaftesbury Avenue London W.C. Engineer do
hereby declare the nature of this invention to be as follows:-
My invention consists of a puncture proof covering for the air tube (or bladder)
in pneumatic tyres also of a metallic air tight non return valve for retaining the
air in pneumatic tyres.
In a rubber tyre I place strips of whalebone (either in the process of manu-
facture) or cemented or secured by fastenings on to the inside of the tyre. The
whalebone may be in strips overlapping or edge to edge, and placed either
longitudinally, transversely or at an angle to the direction of the tyre.
The whalebone may be either moulded into the tyre or fixed to the inner side of
it, or used as a separate layer between the tyre and the bladder, or it may be fixed
to the tyre itself, and the tyre may be used with or without a canvas lining.
Or I make the complete tyre with the whalebone moulded into it, or fixed to its
inner side and I inflate this tyre & so dispense with the separate bladder.
I also use as a cheap substitute for whalebone, what is known as artificial
whalebone (prepared horn) for all the foregoing purposes.
Owing to the rigidity that can be imparted to the tyre by the whalebone or horn
when desired, I can use a very low compression of air.
The air valve I make a plain slide valve inside a case (which is fixed in the
usual manner to the bladder) it has a spring to keep it on to its seating, the
pressure of air in the bladder also keeps it on to its seat, the movement, to open or
shut the valve, is actuated thro' a hole in the seating by a screw or rack & pinion
or a lever.
When the whalebone or horn is used thin in substance, I form it into
corrugations, or I plat several strands together to form a covering for the
bladder.

ROBERT ABRAM LEE 203 Shaftesbury Avenue London, W.C. Engineer, 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 :-
My invention consists of a puncture proof covering for the air tube in pneumatic
tyres also of a metallic air tight non return valve for retaining the air in pneumatic
tyres.
In a rubber tyre-technically known as a cover-I place strips of whalebone,
either in the process of manufacture, or cemented or secured by fastenings on to
the inside of the tyre or cover. The whalebone may be of any required thickness
and width or it may be in strips either overlapping or edge to edge & placed either
longitudinally transversely or at an angle to the direction of the tyres circum-
ference. The whalebone may be either moulded into the tyre or fixed to the inner
27

page_text: side of it or used as a separate layer between the tyre and the bladder itself and
the tyre may be with or without a canvas lining.
Or I make the complete tyre with the whalebone moulded into it or fixed to its
inner side and I inflate this tyre and so dispense with the separate bladder or
air tube.
I also use as a cheap substitute for whalebone what is known as artificial
whalebone (prepared horn) for all the foregoing purposes.
In
Owing to the rigidity that can be imparted to the tyre by the whalebone or
horn, when desired, I can use a very low compression of air in the tyre.
carrying out my invention I fix one or more strips side by side and when using
artificial whalebone in short pieces I fasten them together by rivets or clip pieces.
When the whalebone or horn is placed transversly to the circumference of the
wheel I place the strips with the edges overlapping like a Venetian blind and in
order to keep each one of the strips in its place I shape the ends of these semi-
circular and cement the strips on to canvas or leather this is wrapped over the
whalebone and the edges closely sewn along, and between the rounded ends of the
whalebone to hold the pieces in position, the protector when in the tyre is held in
its place by solutioning it on the canvas of the cover. Whether the strips are
placed with their length in the direction of the circumference of the tyre or
transversly to it I arrange them so that all the joints are covered & no space left
into which a pin or other sharp object might go.
The air valve described in the
Provisional Specification I do not claim as forming part of this invention.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what 1
claim is
1st. Protecting the air tube of a pneumatic tyre by strips of whalebone or
artificial whalebone placed between the cover and the air tube and made of such
size that the part of the air tube liable to puncture is covered by the whalebone or
artificial whalebone protector.
2nd. Protecting the air tube of a pneumatic tyre by strips of whalebone placed
either longitudinally or transversly to the circumference of the tyre.
3rd. The general combination substantially as described forming a complete
protecting covering for the part of the air tube liable to be punctured.
