A Pneumatic Bicycle Inner Tube Cover.
WILLIAM HENRY HALL 39 Hercules Road Lambeth London Harness Maker-
do hereby declare the nature of this invention to be as follows:―
Cut a strip of leather the width required for the inner tube make some holes.
along the edge fasten another strip of leather underneath then sew the ends
together then lace it on the inner tube put it on the wheel and pump the air-
into it.
WILLIAM HENRY HALL 39 Hercules Road Lambeth London Harness Maker
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:―
I will endeavour to explain my invention in the most simple manner I possibly
can, viz. most people know that the football in use at the present time is an india
rubber ball inflated with air inside a ball or covering of leather, the object being
to protect the rubber ball from injury through being put to such rough use, so it is
with the pneumatic bicycle tyre with the exception that the inflated rubber tube is
protected with a covering of the same class of material, which does not answer.
Now my invention is to do away with the indiarubber cover and replace it with
one of leather which will afford a protection of tremendous strength to the inflated
tube inside. Now any harness maker, or saddler, of ordinary skill can prepare this
cover in the following manuer. Cut a straight strip of leather of equal substance
throughout the width to be according to the size of the inner tube when inflated
which you would measure round like measuring round your wrist the edges to come
close together. Now take a tape or string and measure the circumference of the
tube outside, letting the ends of the measure meet together, now you have the
length required cut the ends perfectly straight across now make some small holes
about in. apart and in. in from the edge right along both sides of the leather the
holes to be exactly opposite to each other now cut another strip of leather say
2 in. wide and the same length as the first strip and feather edge it on both edges
with the knife then make a straight line along the cover gin. from the edge and
sew or fasten your narrow strip along the whole length when you have done this
take your ends and sew or fasten them together. Now get a lace long enough to
lace the edges together all round, get your inner tube, not inflated, place it along
the inside of the cover and lace it on, securely fastening the ends, now place it

page_text: on the wheel with the lace in the hollow of the rim and inflate with the air
pump and the leather cover will inflate on to the inner tube.
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 application of leather as a cover for the pneumatic tubes of bicycle
and other carriage wheels in order to resist the injurious effects of sharp flints
nails and other substances.
_ 2. The application_of_leather-as-a-cover-as-aforesaid-in-order-to-prevent-such-
wheels from slipping on the roads.
3. The novelty of the means whereby the leather cover is affixed to the rims-
of bicycle and other carriage wheels.
