PROVISIONAL SPECIFICATION.
Improvements in the Attachment of Pneumatic Tyres to their Rims.
We, JOHN SAMUEL SMITH, of 244, Borough High Street, Southwark, and
CHRISTOPHER JOHN TATE, and GEORGE EDWARD TATE, both of 13, Linton
Street, Islington, all in the County of London, Engineers, do hereby declare the
nature of this invention to be as follows:-
Our invention relates to improvements in the attachment of pneumatic tyres to
their rims.
In carrying out our invention we form upon or attach to the jacket or outer
covering of the tyre at or near the edges thereof a series of loops or pockets of a
width designed to enter between the spokes of the wheel.
Through these loops or pockets we introduce wire preferably in short lengths in
such a manner as to engage with the spokes of the wheel or with eyes or hooks or
with abutments upon the rim.
In practice we find it advantageous to make the jacket or covering of sufficient
width that when applied to the rim the edges will slightly overlap the loops or
pockets upon one edge of the said jacket or covering at one side of the rim passing
between the spokes towards the other side of the rim and vice versa the wires being
then passed through the loop or pockets.

COMPLETE SPECIFICATION.
Improvements in the Attachment of Pneumatic Tyres to their Rims.
We, JOHN SAMUEL SMITH, of 244, Borough High Street, Southwark,
CHRISTOPHER JOHN TATE, and GEORGE EDWARD TATE, both of 13, Linton
Street, Islington, all in the County of London, Engineers, 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 improvements in the attachment of pneumatic tyres to
their rims.
In carrying out our invention we form upon or attach to the jacket or outer
covering of the tyre at or near the edges thereof a series of loops or pockets of a
width designed to enter between the spokes of the wheel.
Through these loops or pockets we introduce wire, preferably in short lengths,
in such a manner as to engage with the spokes of the wheel. It will be seen that
by employing the engaging wires as described a very efficient mode of fastening is
obtained and the rim is not in any way weakened by the use of studs fixed in it or
by making perforations in it for fastenings.
The jacket or covering is inade of sufficient width for the edges of the flaps to
overlap when it is applied to the rim, the loops or pockets upon one edge of the said
jacket or covering at one side of the rim passing between the spokes towards the
other side of the rim and vice versa, the wires being passed through the loops or
pockets on each side of the spokes.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is an elevation of a portion of a wheel having the tyre secured thereto
in accordance with our invention; and,

page_text: igure is a plan of the same, part of the jacket of OC COYering being
back:
Figure 3 is a section drawn to an enlarged scale on the line 3-3, Figure 1;
and,
Figure 4 is a view similar to Figure 3 but shewing the edges of the jacket
disconnected:
Figure 5 is a view shewing how the cover is removed to enable the air-chamber
to be withdrawn.
a is the rim of the wheel, and b, bare the spokes. c is the jacket or outer
covering of the tyre, and d is the air-chamber.
e, e are the loops or pockets formed upon the edges of the said jacket c, the said loops
or pockets being of a width designed to enter between the spokes, as shewn in
Figures 1 and 2. f,f are the wires by means of which the tyres are secured, the
said wires, as shewn, being made of a length to pass over four spokes, but it is
obvious that the length of the wires may be varied to suit the spacing of the
spokes.
In applying the tyre one edge thereof, say the left hand edge as shewn in
Figure 3, is drawn over the rim and between the spokes and then wires are passed
through the pockets on the right hand side of the said spokes; the right hand edge
of the jacket is then pulled over the other edge of the same and secured by wires
on the left hand side of the spokes. In practice we prefer that each wire should
have at one end a loop by means of which it can be manipulated and that when the
wires are applied the other end thereof should just enter the pocket of the adjacent
wire.
In order to withdraw the air-chamber or a portion thereof in case it is punctured,
one or more of the wires immediately adjacent to the air-chamber to be withdrawn
is or are removed and then the covering can be pulled back, as shewn in Figure 5.
9, 9 are bracing flaps secured to the inside of the cover and designed to prevent
the tyre from bulging immediately adjacent to the rim. These flaps however, form
the subject matter of an application No. 23116 dated December 15th 1892 and
therefore no claim is made to them in this application.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
:-
1. A jacket or cover for a pneumatic tyre having the edges divided into a series
of attachment flaps furnished with loops or pockets through which wires are passed
for the attachment of the jacket to the rim of the wheel, each edge of the cover
being separately secured with its own set of wires which engage with the spokes
of the wheel and one series of flaps overlapping the other, substantially as
described.
2. The combination of rim, air-tube, and jacket with its loops and wires, each
edge of the jacket being separately secured with its own set of wires, substantially
as described.
