page_text: I, LOUIS Cox of 23, Cannon Street Birmingham in the County of Warwick Outfitter
do hereby declare the nature of this invention to be as follows:-
In carrying out my Invention I use an inner inflatable tube constructed in the usual'
manner.
I use an outer cover constructed of leather, the strips of leather to form the outer
cover are cut of a width suitable to encircle the inner tube and are cut crosswise
of the skin that is from flank to flank not from head to tail. Two or more strips are
joined end to end to make the strip of sufficient length to fit the rim. The leather.
may or may not be lined with canvas, the canvas may be cut upon the bias or
straight.
:
The edges of the outer cover may be sewn together to form a complete outer tube or
the edges may be cemented. together with a strip of leather or canvas, or the edges
may be laced or hooked or otherwise suitably fastened together.
The leather may be treated with Ammonia, and with suitable oils, fats, soaps,
Alums, and the like to make the leather more pliable more wet resisting and more
puncture resisting.
The rim may be of any convenient section preferably concave.
I find that with a leather outer cover cut in the manner I have described I am
able to utilize the natural arrangement of the fibres of the leather so that the effect
of inflating the inner tube when encircled by its leather cover is to cause the leather
tubular ring to greatly contract in its circumferential length.. I find that the con-
traction of the leather produced in the manner aforesaid is sufficient to firmly secure
the Tyre to the rim without the necessity for any other fastening.

I Louis Cox of 23 Cannon Street Birmingham in the County of Warwick outfitter
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 object is to provide a pneumatic tyre which can be attached to the rim by the
contractile action of the cover.
For this purpose I construct the cover of leather cut crosswise of the skin, that is,
from flank to flank, not from head to tail. Two or more strips can be joined end to

page_text: end to form a strip of sufficient length to fit the rim. The leather may if desired be
lined with canvas cut on the bias or straight. The edges of this outer cover can be
hooked sewn or otherwise detachably or non-detachably secured together so as to
enclose the inner tube.which is of any ordinary form. I prefer that method of fasten-
ing together the cover which will least interfere with its contractile action such as
hooks on one edge of the cover and eyes on the other edge of the cover but I do not
desire to limit myself to any particular mode of fastening provided that the contractile
action of the leather is capable of operating.
In order to make the leather as pliable, tough, puncture proof and wet resisting as
possible it may be treated with ammonia, and with suitable oils, fats, soaps, alums
and the like in manner well understood.
My tyre can be fitted to almost any of the known forms of rim. The size of the
tyre is preferably such that when inflated it can be sprung into the rim but in any
event it must not be so large that the contractile action of the cover will not
securely fix it to the rim when the inner tube is inflated. As the inner tube is inflated
the cross sectional area of both cover and inner tube increases whilst the peripheral
length of the leather cover decreases thereby causing the tyre to grip the rim so
firmly that no other attachment is necessary.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
A pneumatic Tyre in which the leather cover enclosing an inner tube is
attached to the rim by the contractile action of the outer leather cover the whole
being combined and arranged substantially as described.
