COMPLETE SI DUIT TOATIVA,
Improvements in and connected with Pneumatic Tyres and Rims
therefor.
1, JAMES HAROLD BARRY of 4 Cadogan Terrace Victoria Park in the County
of Middlesex 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 consists of improvements in and connected with pneumatic tyres
and rims therefor.
To carry this into effect I make my tyres of a material which from its elastic
properties will give the greatest amount of resiliency with strength and lightness,
which is an elastic webbing or netting or loose woven cloth of a fine mesh,
composed of horse hair and linen, or hemp, or other like fibre in combination or
separate. The horsehair and linen or other like fibre may be arranged in alternate
threads, or 1 may make the horsehair in one direction and the fibre in the
other, crossing each other and forming a kind of netting similar to muslin or fine
fish netting, so that when rubber, gum gutta or other clastic material is
incorporated therewith, or solutioned or vulcanised thereto, or rolled with it under
pressure it will enter into and unite through the pores and practically form one
cloth.
I may for some purposes make my cloth of greater thickness by pressing the
loose woven cloth or netting between two thin sheets of rubber, the same entering
into and uniting through the pores of the netting, or when more than usual strength
is required I may make several thicknesses of this cloth.
It has been found that the tendency of the rims for pneumatic tyres as at
present constructed is to cause more or less of the air contained in the same
to be cushioned against them, thus losing an amount of its speed giving
properties. I propose to obviate this by arranging my rims so that the inner
periphery of the tyres shall never come into contact with them thus giving all the
air full play.
I carry this into effect by suspending my tyres between two side rims or
rings to which the spokes are attached, or I may connect these side pieces or
rings, by arches or bridges forming a skeleton or deep rim.
I sometimes use a flexible band connecting the two side pieces and against which
the tyre is held. I secure the tyre to my side pieces or rims which may take
different forms by means of buttons, revolving pins wiring or other convenient
arrangement or I may in the event of using a single tyre solution the same into the
Hexible band.
In some cases I use a continuous cover completely encircling the inner tube,
being first fastened at one side to the side rim and continued around the inner tube
to the opposite side rim, and secured and fixed thereto by means of a ridge of
rubber or other material made on and around it, or by studs made in or with
the said cover fixing into slots or holes in the side rim, or by wires or other
devices, it is then continued around the inner tube, to the first mentioned fixed
part and secured thereto by similar devices, thus making a complete cover for the
inner tube.
To enable my invention to be more particularly understood aud carried into
effect I will proceed to describe the same with reference to the accompanying
drawings in which Fig. 1, Fig. 2, Fig. 3, Fig. 4 Sheet 2, and Fig. 2 and 3 Sheet I
are sections of the tyres, side rims and flexible bands.

K. Fig. Sheet 1 and Figs. 2, 3 and 5 Sheet 2 is a fastening for the tyre to the
side rim which for the split cover E Fig. Sheet I may be arranged to

Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I wish it understood
that reserve the right to use these tyres with other forms of rims, and these
rims may be adapted to other tyres but what I desire to secure by Letters
Patent is ·
1. A pneumatic tyre constructed of an elastic webbing, or netting or loose
woven cloth of a fine mesh, composed of horschair and linen, or hemp, or other
like fibre in combination or separate, the horsehair and linen or other like fibre
being arranged in alternate threads, or the horse-hair in one direction and the fibre
in the other, crossing and forming a netting and incorporated with rubber, guin
gutta or other elastic material.
2. A pneumatic tyre the cover of which is arranged and secured to its side rims
us set forth in the foregoing Specification and as at Figure 1, Sheet 1 of the
drawings.
3. A tyre the rim of which is formed of side rings or pieces, carrying between
them a flexible band forming part of the cover for the tyre, the said side
rings or pieces being coupled together by crossed and vertical spokes.
4. Tyres the rims of which are so arranged that they only come in contact
at or near their sides the spokes being carried to bridges or arches connecting
them.
5. Tyres and rims made and applied as before described and set forth in the
foregoing Specification and accompanying drawings.
