PROVISIONAL SPECIFICATION.
Improvements in and relating to Pneumatic Tyres.
I, WILLIAM HOWARD of 108 Charing Cross Road in the County of London,
Boot Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The chief object of this invention is to facilitate the repairing of pneumatic
Tyres, by making and attaching the covering so that it may be easily detached
from the rim and opened at any desired point in order to obtain access to the
air bag.
According to this invention, for cycle wheels I form the cover preferably of a
number of pieces of canvas, (cut all exactly alike) for example, of such a shape
that when they are fastened together they shall form an endless band capable
of enclosing the air bag entirely (forming the covering) as hereafter described.
All round each of the edges of the said endless band I form or attach loops or
pockets at such distances apart that the loops or pockets on one edge shall go in
between those on the other edge, in order that a cord may be passed through the
whole of the loops or pockets so as to lace the two edges together and form a flat
surface where the lacing comes. I propose to have a flap of leather or other
suitable material, fixed near one of the edges of the aforesaid endless band so
as to cover the air bag completely when the cover is laced on.
When the Tyre as above constructed, is placed on a hollow rim, for example,
and inflated it will become firmly attached thereto.
For heavy vehicles, I propose to fix the Tyre between two rims and have the
cover made of leather cut in the manner before described and made into an
endless band, so as to envelope the air bag, but having the edges laced together
(in the manner afore aid) on the outside of the ring formed by the band, instead
of on the inside as aforesaid. I provide bolts passing through the rim to keep
the cover in position, also a band round the. inside of the cover at the bottom,
opposite to the opening and the two ends of such band overlap and are fastened
together by the inflating valve.
The pockets or loops aforesaid are formed on two separate strips of leather
which are sewn on to the edges of the endless band so that the extra thickness
holds the Tyre on to the aforesaid outer rim.

page_text: manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
The chief object of this invention is to facilitate the repairing of pneumatic
tyres, by making and attaching the covering so that it may easily be detached
from the rim and opened at any desired point in order to obtain access to the
air bag.
According to this invention, for cycle wheels I form the cover preferably of a
number of pieces of canvas, (cut all exactly alike) for example, of such a shape
that when they are fastened together they shall form an endless band capable
of enclosing the air bag entirely (forming the covering) as hereafter described.
All round each of the edges of the said endless band I form or attach loops or
pockets at such distances apart that the loops or pockets on one edge shall go in
between those on the other edge, in order that a cord may be passed through the
whole of the loops or pockets so as to lace the two edges together and form a flat
surface where the lacing comes. I propose to have a flap of leather or other
suitable material, fixed near one of the edges of the aforesaid endless band so
as to cover the air bag completely when the cover is laced on.
When the tyre as above constructed is placed on a hollow rim for example,
and inflated it will become firmly attached thereto.
For heavy vehicles I propose to have the tyre fixed between two rims and have the
cover made of leather cut in the manner before described and made into an
endless band, so as to envelope the air bag, but having the edges laced together
(in the manner aforesaid) on the outside of the ring formed by the band, instead
of on the inside as aforesaid. I provide bolts passing through the rim to keep
the cover in position, also a band round the inside of the cover at the bottom,
opposite to the opening and the two ends of said band overlap and are fastened
together by the inflating valve.
The pockets or loops aforesaid are formed on two separate strips of leather
which are sewed on to the edges of the endless band so that the extra thickness
holds the tyre on to the aforesaid outer rim.
And in order that my said invention may be better understood I will now
proceed to describe the same with reference to the drawings accompanying this
specification in which Figs. 1 to 5 inclusive shew details of my invention
applicable for tyres for heavy vehicles. Fig. 1 is a plan of a portion of a tyre
with the outer steel rim removed. Fig. 2 shews the shape of the pieces of leather
which I employ for forming the covering of the tyre. Fig. 3 the shape of the
pieces constituting the lining of the said cover. Fig. 4 a section of the complete
tyre. Fig. 5 an elevation of a portion of a complete tyre. Figs 6 and 7 shew
details of my improved tyre for velocipedes and other very light vehicles. Fig. 6
shews a section of the strip forming the outer covering, and Fig. 7 a section of
the complete tyre.
The same letters denote the same parts in all the views.
a shews the outer covering, the air chamber, e c¹ the rims. The construction
of the tyre shewn at Figs. 1 to 5 is as follows:-
The outer covering which I prefer to form of leather (a) is formed of a number
of strips a stamped out into the shape shewn at Fig. 2, sewn, rivetted or other
wise connected together. A lining d formed of a number of strips of leather d¹
of the shape shewn at Fig. 3, suitably joined together, is fitted in the outer
covering a. The thickness of each leather strip d' is reduced at the edges so that
a amooth surface is produced inside. This lining acts as a further protection to
the air bag and serves to prevent the outer covering from stretching on account
of the pressure of air in the tyre. A strip of leather e provided with loops or
pockets f, is suitably attached to one edge of the covering a outside and extending
all round the tyre.
A similar strip e' is attached to the other edge, this strip has also loops
or pockets f¹. Fig. 1 shews how the loops or pockets f f¹ engage with one
another so that a cord g may be passed through the said loops or pockets in order

page_text: to draw the edges of the outer covering tightly together. A steel rim c¹ is fitted
over these leather strips e e¹ and is held in place by the thickness of these latter
and by a few bolts as shewn at Fig. 5. Bolts secure the tyre to the inner
rim (see Fig. 4), and bolts h (see Fig. 5), may be employed to further secure
the rim c to the tyre. k in Fig. 4 shews a strip of leather extending round the
tyre where the latter is in contact with the rim c. By making the covering a
of pieces stamped of the shape shewn at a¹ on the drawings I am enabled to
form an entire ring completely covering the tyre.
At Figs. 6 and 7 (which shew my tyre constructed for velocipedes and other
very light vehicles) the loops or pockets f f are shewn attached to the under
side of the outer covering a and when the cord g is inserted, and the tyre inflated
it will be firmly held on to the rim c owing to the thickness forming the pockets
er loops.
Although I have described the outer covering and the lining as made of
leather (which I prefer) I may make these of any other suitable material.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. In pneumatic tyres for vehicles, the employment of a covering composed of
a number of pieces formed as shewn at a¹ on the accompanying drawings all
substantially as and for the purpose set forth.
2. In pneumatic tyres, the employment of a lining to the outer covering
composed of a number of pieces as shewn at d' on the accompanying drawings
substantially as and for the purposes set forth.
