Road, Woolwich, aforesaid, and W. T. HENLEY'S TELEGRAPH WORKS
COMPANY LIMITED, of 27 Martin's Lane, Cannon Street, London E.C. India-
rubber and Guttapercha Manufacturers, do hereby declare the nature of this
invention to be as follows :—
Our invention relates to pneumatic tyres for bicycles and other vehicles and it
has for its object to provide an attachinent which while permitting of the tyre
being readily applied to the wheel and removed therefrom will nevertheless avoid
all liability of the tyre becoming accidentally detached from the wheel even when
deflated and prevent what is known as "creeping" of the tyre which is at present
so apt to occur owing to the looseness of the connection between the cover and the
air tube and of the tyre with the rim of the wheel.
A further object of our invention is to protect the air tube from perforation.
In tyres as at present made the air tube and its cover are two separate pieces
which when applied to the rim are so far independent of one another as to
permit of the cover slipping on the air tube. This we avoid by making the air
tube and its cover practically one piece, the cover to this end being provided
with a lateral extension or fly portion which extends the whole length of the cover
and serves for the attachment of the air tube which is cemented to the cover so
that the two portions are integral.
In
The combined air tube and cover are secured to the rim by wires which extend
around each edge of the cover and through openings in the rim to the rear side of
the latter where they are made fast. The rim near one edge is provided with
two openings placed circumferentially about (say) one inch apart, of a size to
permit of the ready passage of the ends of the wire and united by a slot which
serves to enable one end of the wire when passed through to the back of the
rim to be drawn on for the purpose of tightening the cover on the rim.
line with these openings and near to one of them, a pin is fixed to the inside of
the rim. That end of the wire which points from the openings towards the pin,
is passed through the opening farthest from the latter, to which it is secured either
by being looped over it or passed through a hole in the pin, in which case the end
of the wire may be screw threaded and provided with a nut to draw the wire
tightly through the hole. The wire now lies across the opening which is next to
the pin. Through this opening the other end of the wire is passed, and hooked
over the over lying portion.
Each edge of the tyre is similarly attached but the attachments preferably
occupy diametrically opposite positions on the rim.
Protection against perforation is obtained by providing the air tube with a strip
of leather which may be left loose or cemented to the inner surface of the cover
and replaces the usual india rubber lining. The strip is preferably made somewhat.
thicker along its centre where the risk of damage is greatest.

We, JAMES HENRY ALBERT WOODS, Artisan, of 26, Albert Road, Woolwich,
in the County of Kent, and EDWARD THOMAS WOODS, Artisan, of 24, Albert
Road, Woolwich aforesaid, and W. T. HENLEY'S TELEGRAPH WORKS
COMPANY, LIMITED, of 27, Martin's Lane, Cannon Street. London, E.C. India-
rubber and Guttapercha Manufacturers, 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:-
Our invention relates to pneumatic tyres for bicycles and other vehicles, and it
has for its object to enable the tyre to be readily applied and removed without the
possibility of the tyre, even when deflated, becoining accidentally detached from
the wheel, a further object being to prevent "creeping" of the tyre upon the wheel
and to protect the air tube from perforation.
Instead of making the air tube and its cover entirely separate, as usual, the
cover is provided with an extension or fly portion along the whole of one edge to
which the air tube is cemented so that the two,-air tube and cover,-are
practically one, the combined air tube and cover being secured to the rim by wires
applied to the cover and secured to the rim in the manner hereafter described
with reference to the accompanying drawings forming part of this Specification,
wherein
Figure 1 shews in cross-section and perspective the inflated tyre, as applied to
the rim.
Figure 2 shews the tyre deflated and removed from the rim.
Figure 3 shews on a larger scale the mode of fastening the wires to the rim.
A is the air tube made in the ordinary way and B the protective cover.
Instead
of the two being separate as usual, the air tube is solutioned to the fly portion b of
rubber which extends beyond the canvas lining ', of the cover so that the air tube
and cover are for all practical purposes one and when applied to the wheel, their
relative position cannot become altered by the "creeping" of the one on the other.
For the purpose of securing the combined air tube and cover to, and of preventing
their creeping upon, the wheel rin, wire cords C are enclosed in sheaths formed by
the inwardly turned and cemented edges of the canvas lining 61, of the cover, the
one wire cord being situated just within the fly portion 6 by which the cover and
tube are united and the other at the opposite edge of the cover. These wires are
secured to the rim preferably at diametrically opposite points of the circumference
of the wheel rim, the means of attachment being alike for both and consisting of a
hook e brazed to one end of the wire cord, which is hooked into an oblong hole or
slot d in the rim, and of a tag e brazed to the other end of the cord which is passed
through the same hole or slot d and enables the cord to be drawn tight around the
rim in the hollow of which it lics, as shewn, the tag being secured by one or other
of a series of holes in the tag being engaged upon a stud g fixed to the rim and
provided with a nut or head to retain the tag in engagement therewith. Instead
of the hook and tag being passed through the same slot, the hook might be
engaged in a hole separate from the slot, through which the tag is passed, and
instead of the tag being hitched on to a stud, it might consist of a screw threaded
rod and be passed through a hole in the stud g and provided with a nut by
which to draw the wire tight.
In order to protect the tyre against perforation, a soft leather lining strip D is
cemented to the canvas lining of the cover.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A pneumatic tyre whereof the inflatable air tube or chamber and the cover
are permanently united, substantially as and for the purpose specified.
2. The herein described means of securing to the wheel rim the cover portion of
a combined air tube and cover, consisting of wire cords embedded in the cover and
having hook and tag fastening devices adapted to be passed through and engaged
with the wheel rim, substantially as specified.
