PROVISIONAL SPECIFICATION.
Improved Means for Securing Elastic Tyres to the Rims of Wheels.
I, JOHN BOYD DUNLOP, of Talbot House Blackrock Dublin Ireland Veterinary
Surgeon, do hereby declare the nature of this invention to be as follows:-
My invention relates to means for securing elastic tyres to the rims of wheels.
Various methods have been heretofore described of securing elastic tyres to the
rims of vehicles by means of wires or bands which are passed through or over
some portion of the tyre and round the rim of the wheel. The chief object of my
present invention is to so provide that the ends of such wires or bands may be
secured to the rim and detached therefrom more readily than heretofore.
According to my invention I braze or otherwise secure to the rim split or slotted
rings or tubes. One or both ends of the binding wires or bands are screw-threaded
and are furnished with nuts. The said binding wires or bands being in position
in or upon the elastic tyre, their screw-threaded ends with the nuts screwed thereon
are passed through the slits or slots so that the said wires or bands lie in the rims
or tubes. The nuts are then screwed up against the ends of the split or slotted
rings or tubes the wires or bands being thereby drawn tightly round the rim.
I prefer to make one face of each of the nuts convex and the corresponding end
of the split ring or tube against which the said nuts are screwed, concave, so that
they may take suitable bearing thereon.
When it is desirable to pass the screw-threaded ends of the wires of bands to
the outside or to the side of the rim nearest the hub I form a slot in the rim
corresponding with that in the ring or tube. When one end only of each of the
binding screws or bands is screw-threaded and furnished with a nut 1 secure the
other end of each wire or band by means of a hook or a eye formed on said end of
wires or bands, and a suitable button or hook on the eye of the rim.
By my invention the binding wires or bands can be very firmly secured to the
rim, and also loosened and removed from the same much more easily and expe-
ditiously than has heretofore been possible.

COMPLETE SPECIFICATION.
Improved Means for Securing Elastic Tyres to the Rims of Wheels.
I, JOHN BOYD DUNLOP, of Talbot House, Dublin, Ireland, Veterinary Surgeon,
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 means for securing elastic tyres to the rims of wheels.
Various methods have been heretofore described of securing elastic tyres to the
rims of vehicles by means of wires or bands which are passed through or over
some portion of the tyre and round the rim of the wheel. The chief object of my
present invention to so provide that the ends of such wires or bands may be
secured to the rim and detached therefrom more readily than heretofore.
According to my invention I braze or otherwise secure to the rim split or slotted
rings or tubes. One or both ends of the binding wires or bands are screw-threaded
and are furnished with nuts. The said binding wires or bands being in position
in or upon the elastic tyre, their screw-threaded ends with the nuts screwed thereon
'

or tubes.
The nuts are then screwed up against the ends of the split or slotted
rings or tubes the wires or bands being thereby drawn tightly round the rim.
In the accompanying drawings, I have shown how my invention may be
conveniently carried into practice.
Figure 1 is a side view of part of the rim of a wheel and tyre provided with my
invention.
Figure 2 is a section on the line a, a, Figure 1.
Figure 3 is a section on the line y, y, Figure 2.
A is the rim of the wheel, B, B are the tubes secured thereto by any suitable
means said tubes being split or slotted as shewn at B¹. C, C are the binding wires
which hold the tyre in place on the rim. The wires are screw-threaded at the
ends and are furnished with nuts C screwed thereon so that the said uuts abut
against the end of the tube. If desirable the tubes may take the form of rings,
that is to say they may be made short axially in comparison with their diameter.
I prefer to make one face of each of the nuts convex, and the corresponding end
of the split ring or tube against which the said nuts are screwed, concave, so that
they may take suitable bearing thereon. When it is desirable to pass the screw-
threaded ends of the wires or bands to the outside, or to the side of the rim nearest
the hub I form a slot in the rim corresponding with that in the ring or tube. When
one end only of each of the binding wires or bands is screw-threaded and furnished
with a nut I secure the other end of each wire or band by means of a hook or
eye formed on said end of wires or bands, and a suitable button or hook or
eye on the rim.
By my invention the binding wires or bands can be very firmly secured to the
rim, and also loosened and removed from the same much
more easily and
expeditiously than has heretofore been possible.
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. Securing an elastic tyre to the rim of a wheel by means of wires or cores passing
through the edges of the tyre, in combination with split or slotted tubes or rings
secured to the rim, in which tubes or rings the wires or cores are inserted and then
tightened substantially as, and for the purpose, specified.
2. A velocipede wheel having a rim to which split or slotted tubes or rings are
secured, substantially as described with reference to the accompanying drawings,
for the purpose specified.
