PROVISIONAL SPECIFICATION.
An Improvement in or relating to a Protector for the Air Tube of a
Pneumatic Tyre.
WILLIAM HENRY BRASSINGTON 35 Cable Street Manchester Manufacturer
do hereby declare the nature of this invention to be as follows:-
To effect my improvement I place between the air tube and the outer rubber
casing a prepared skin covering of horse, cow, pig, calf, goat, deer, buffalo, or any
other skin, suitable for the purpose the skins being so prepared as to resist a
puncture from any sharp instrument it may come in contact with. I also claim the
making of a complete tube if so required.

COMPLETE SPECIFICATION.
An Improvement in or relating to a Protector for the Air Tube of a
Pneumatic Tyre.
1, WILLIAM HENRY BRASSINGTON, of 35 Cable Street Manchester, Manufacturer,
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:-
The improvement relates to a protector for the air tube of a pneumatic tyre, and
has for object to prevent such air tube being punctured or burst by contact with
any sharp instrument or object.
To accomplish this, and to effect my improvement, I provide a strip or strips of
skin of horse, cow, pig, calf, goat, deer, buffalo, or any other suitably prepared
skin, (such not being tanned as ordinary leather), to form the required protective
covering.
This skin is treated or cured, in manner well understood, so as to cause it to
possess a larger amount of toughness than is possessed by ordinarily tanned leather,
which enables it to very effectively resist puncture from any sharp instrument or
object coming in contact therewith.
I place this strip or covering of skin, so prepared, between the air tube, and the
outer casing or outside covering of the tyre, but all round such air tube, or so as to
completely cover or protect the same, by preference as an intermediary casing or
tube, so that, in case such outer casing or covering is pierced, the penetrating object
is prevented from coming in contact with the air tube behind or within the protective
skin aforesaid, and accidental deflation from puncture, as well as bursting, may
thereby be avoided.
Variations in the methods of treating or curing the skin, which are such as are
ordinarily understood, may be made, and likewise such toughened skin may be
applied to the tyre in any convenient manner, as for instance it may be composed of
one strip, of the length necessary to enclose the complete air tube, or it may be
composed of several shorter strips, each enclosing a portion of the length of the air
tube; also the hide protector may either be constructed in tubular form round the
air tube, by means of cementing, lacing, or otherwise, prior to attachment to the rim
of the wheel, or it may be arranged to simply enfold the air tube, or completely
cover or protect the part thereof not protected by the rim of the wheel, and be held
Do

clips, laces, or other means of attachment, but always in such manner that the inner
air tube is entirely protected by this covering shield or tube of prepared hide or
skin; and other variations in detail may be made, without departing from the
peculiar character of the invention.
I am aware that a longitudinal strip or strips of various and similar substances
have been employed for the protection of pneumatic cycle tubes, which were laid
longitudinally between the tube and the outer casing; but such are for the most
part imperfect in their action, and I do not desire to claim such arrangements,
whether composed of the particular substance herein described or of other
substances.
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 Į
claim is :-
:-
A protector for the air tube of a pneumatic tyre, composed of cured or toughened
skin, formed all round such air tube, or completely covering the portion unprotected
by the rim of the wheel, and placed between such air tube and the outer casing of
the tyre, in manner substantially as herein set forth.
Dated this 24th day of August 1893..
