PROVISIONAL SPECIFICATION.
A Method of Securing Wires for the Attachment of Pneumatic
Tyres.
WILLIAM HENRY CRESSWELL Woodley Bank Woodley Cheshire Engineer
do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide a method of securing wires for the
attachment of pneumatic tyres.
For this purpose I provide a wire (such as is generally used in the construction
of pneumatic tyre covers) the ends of which overlap and are turned out at right
angles and may pass through holes in the sides of the rim-thus one wire resting
on top of the other and though the ends of the wire remain in the rim when the
tyre is deflated I may further secure them by means of nuts or fastenings and may
not pass them through the rim but allow them to remain within the cover of
the tyre.
This
I may also attach a small band, or sheath around the wire at that portion where
it laps so that the ends of the wire being passed through and held in position are
thus prevented from increasing the circumference of the edge of the cover.
band or sheath may be brazed on one portion of the wire, or may be loose and
covering both overlapping parts. I may also use 'flat bands of steel or other
material in lieu of wires.

A Method of Securing Wires for the Attachment of Pneumatic
Tyres.
I, WILLIAM HENRY CRESSWELL, of Woodley Bank, Woodley, Cheshire,
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 relates to a method of securing wires for the attachment of
pneumatic tyres to the wheel rims of cycles and other vehicles.
In carrying my invention into effect I employ two wires embedded one in each
edge of the outer covering of the pneumatic tyre. The ends of each wire are
bent at a right angle and lie in a sheath and are passed through holes in the
wheel rim, and may or may not be further secured by means of nuts or other
fastenings.
And in order that my invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 is a side elevation of a short portion of a cycle wheel rim, pneumatic
tube and outer covering. Fig. 2 is a transverse section taken on the line A A,
Fig. 1, and Fig. 3 is a plan of Fig. 1, partly in section; these views show an outer
ΓΙ

page_text: covering attached to a wheel rim by wires which are secured according to my
invention and Figs. 4, 5 and 6 are detailed views of parts of the same.
In the drawings,-a represents the wheel rim which is preferably of the shape
shown in the sectional view, Fig. 2, b is the pneumatic tube and c the outer
covering or envelope for the tube. In each edge of the cover c is embedded a
wire d the ends of which overlap as shown clearly in Figs. 3, 4, 5 and 6 and are
passed through a metal sheath e which is also embedded in the edge of the cover.
Each end of the wire projects about half an inch beyond the sheath where it is
bent over at about a right angle and then passed through a hole made in the rim
whereby the ends of the wire are secured together and the cover c is firmly
attached to the rim a.
If thought desirable for further security the ends of the wires can be threaded
and a nut screwed upon each to lock the ends of the wires on to the rim as shown
clearly in the drawings.
As an alternative one end of the wire can be bent at a right angle and threaded
as before described and the bent portion passed through a hole in a narrow strip
of metal and the other straight end of the wire bent over the plate up to the hole.
The edges of the metal strip can then be turned over to form a sheath and brazed
on to the unbent end of the wire. The edge of the cover with the sheath in
position can then be laid on the rim through a hole in which the bent threaded end
of the wire is passed and then secured by a nut f screwed upon it.
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. In a pneumatic tyre, an outer covering having a wire embedded in each edge,
the ends of the wires being bent and passed through a sheath and through holes
in the wheel rim and secured by nuts or otherwise substantially as and for the
purposes herein set forth.
2. In a pneumatic tyre, a metal sheath substantially as herein set forth for
connecting together the ends of the wires embedded in the edges of the outer
covering.
