PROVISIONAL SPECIFICATION.
Improvements in and relating to Pneumatic Tyres.
We, KATE WILTON Cox, of 38, Carlyle Road, Edgbaston, Birmingham, and
GEORGE WARNER, of 50, Whateley Road, Handsworth, Birmingham, Manager, do
hereby declare the nature of this invention to be as follows:-
The object of our present invention is to improve the means of attachment of
pneumatic tyres to the rims of wheels and the fastening together of the edges of
the cover in such a manner that the inner tube can be readily accessible for any
purpose.
The cover which is of canvas or other suitable material completely encircles
the inner tube. The outside of the cover consists of india rubber or other suit-
able substance. The overlapping edges of the said cover preferably contain in
one or both sides strips of leather or other material to strengthen same. At
suitable distances apart circumferentially in one of the overlapping edges are
provided oblong eyeletted holes, and corresponding to these holes upon the other
overlapping edge are the fastenings formed thus.
Strips of metal of convenient length are enclosed circumferentially in the edge
of the cover, these strips or lengths carry movable stud fastenings, preferably two
studs on each length and pivotally attached to the strips by loosely connecting
the stems to same, at similar distances apart circumferentially as are the oblong
holes on the opposite edge, these studs which have narrow heads in the one
direction protrude through the material of the tyre cover, and the said heads
are undercut to form flanged catches, thus when the two edges of the cover are
overlapped the heads are passed through the oblong holes and the studs turned
crossways on their centres so that the flanged heads catch upon and grip the sides
of the oblong eyeletted holes in their narrow part, thus a secure fastening is
provided which however can be easily unfastened when the tyre is deflated.

Improvements in and relating to Pneumatic Tyres.
We, KATE WILTON Cox, of 38; Carlyle Road, Edgbaston, Birmingham, and
GEORGE WARNER, of 50, Whateley Road, Handsworth, Birmingham, Manager, 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
Di Q77

page_text: statement, reference being had to the drawings accompanying this specification
and to the figures and letters shewn thereon.
Similar letters of reference denote similar parts on the several figures.
The object of our present invention is to improve the means of attachment of
pneumatic tyres to the rims of wheels and also to provide an efficient fastening
for fastening together the edges of the cover in such a manner that the inner air
tube can be readily accessible for any purpose. Figure 1, represents in part
perspective the cover with our improved method of fastening in connection with
same. Figure 2, represents a cross sectional view. Figure 3, represents another
cross sectional view. Figure 4, represents a view of the underside of the tyre
cover shewing same closed with the fastenings in their normal position when locked.
Figure 5, represents in side view the fastenings with their back plate. Figures 6
and 7, represent plans of same.
We construct the cover A, of the tyre of canvas or other suitable material which
completely encircles the inner tube or air chamber B but is not itself a complete
tube being divided circumferentially where it rests within the rim. The outside
of the cover A is covered with india rubber A¹ or other suitable wear resisting
substance so as to form the tread portion of the tyre. The overlapping edges of
the said cover A preferably contain in one or both sides strips of leather a, a',
or other material to strengthen same which is cemented sewn or otherwise attached
or the strip of leather secured thereto on one edge of the cover and the strip of
leather secured to the other edge of the cover, may slightly overlap one another.
The inner tube B is placed within the cover A and the edges of the cover A are
secured in the following manner.
At suitable distances apart circumferentially in one of the overlapping edges
the cover is perforated with oblong holes C which are eyeletted and corresponding
to these holes on the other overlapping edge are the metal fastenings D which
are formed thus. The fastenings employed are of a special construction and con-
sist of strips or back plates of metal of convenient length and width which are
enclosed circumferentially in the edge of the cover these strips or back plates 1)
carry movable or revolving stud fastenings D at corresponding distances apart
circumferentially relative to the position of the oblong eyeletted holes Cupon the
opposite side a, of the cover. There are preferably two studs on each metal strip
attached by pivotally connecting the shouldered stems to the metal strip or back 1
with a metal disc or washer in each case, such as by loosely riveting through
same, the said revolving studs D have narrow heads in the one direction and
protrude through the material of the cover A upon the side a¹. The said heads
are undercut to form flanged catches, thus when the two edges of the cover are
brought together and overlapped the oblong holes Care passed over the heads of
the fastenings D and the said studs are turned crossways on their centres so that
the flanged heads catch upon and grip the sides of the oblong eyeletted holes in
their narrow part, and thus a secure fastening is provided which however can
be easily unfastened when the tyre is deflated by turning the revolving studs so
that they can slip through the eyeletted holes.
A tyre so constructed will on inflation be securely fixed to the rim without
the use of cement or other methods of fastening.
The arrangement of fastening herein described and illustrated can be modified
as occasion may require without materially departing from the principle of our
invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is;-
.
Firstly. A pneumatic tyre for cycles and other vehicles consisting of a cover of
canvas or other suitable material, a ring or two rings of leather firmly secured to
one or both edges of the cover, the edges of the cover or the edges of one or both
of the leather rings overlapping. Oblong eyeletted holes cut circumferentially

page_text: in the one overlapping edge of the cover, turning or revolving stud fastenings
upon the corresponding overlapping edge of the cover for engaging the oblong
eyeletted holes, for securing the two edges of the cover together; an inner
inflatable tube and a suitable tread, all combined and operating together substan-
tially as herein before described and illustrated.
Secondly. In a pneumatic tyre for cycles and other vehicles, the use for the
purpose of securing the two overlapping edges of the cover together and the tyre
to the rim of a fastening consisting of oblong eyeletted holes made to engage
with turning or revolving studs upon a back plate such as hereinbefore described
and illustrated in Figures 1 to 7 of the drawings.
Dated this 4th day of April 1900.
