PROVISIONAL SPECIFICATION.
Improvements in Pneumatic Tyres for Motor Carriages and Heavy
Vehicles.
I, WILLIAM HOWARD, of 13, Theobald's Road, in the County of London, Boot
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to pneumatic tyres for motor-carriages and heavy vehicles
and has for its chief object means for securing the tyre to the rim of the wheel.
According to this invention I cover the air bag with a covering built up of
pieces of leather, preferably of the shape shewn on the drawing accompanying
this specification. The said cover is secured by sewing or lacing to
its edges a strip of leather and canvas or other suitable material provided with
lugs or flaps as hereafter described. The strip I make as follows:
I take a strip of leather and in this I cut a number of longitudinal slots (I
have found eight to answer well) and through each of these slots I pass two
pieces of leather (forming the lugs aforesaid). I turn and stick down the inner
ends of these pieces, on to the under side of the leather strip aforesaid. I then
cement a strip of canvas or other suitable material over the said turned-down
ends of the leather pieces and the underside of the leather strip.
I further cover the tyre made as above with a covering of leather between two
layers of canvas. This cover is built up of a number of pieces so as to form a
ring to fit over the tyre, the edges of this cover may be secured by means of a
band or strip of canvas cemented over the edges of the last mentioned covering.
The whole is then suitably enclosed in an ordinary outer rubber covering.
For securing the tyre to the rim of wheel. I have slots in such rim corres-
ponding to the aforesaid lugs, these latter enter into said slots and are held
therein by bolts. Or in the case of divided or double wheels the said lugs could
be bolted in between the two sections of the wheel.

Improvements in Pneumatie Tyres for Motor Carriages and Heavy
Vehicles.
I, WILLIAM HOWARD, of 13. Theobald's Road, in the County of London, Boot
Manufacturer, 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:-
This invention relates to pneumatic tyres for motor carriages and heavy vehicles
and has for its chief obiect means for securing the tyre to the rim of the wheel.

page_text: According to this invention I cover the air bag with a covering built up of
pieces of leather, preferably of the shape shewn on the drawing accompanying
the Provisional Specification. The said cover is secured by sewing or lacing to
its edges a strip of leather and canvas or other suitable material provided with
lugs or flaps as hereafter described. The strip I make as follows:-
I take a strip of leather and in this I cut a number of longitudinal slots (I
have found eight to answer well) and through each of these slots I pass two
pieces of leather (forming the lugs aforesaid), I turn and stick down the inner.
ends of these pieces, on to the under side of the leather strip aforesaid. I then
cement a strip of canvas or other suitable material over the said turned-down
ends of the leather pieces and the underside of the leather strip.
I further cover the tyre made as above with a covering of leather between two
lavers of canvas. This is built up of a number of pieces so as to form a
ring to fit over the tyre, the edges of this cover may be secured by means of a
band or strip of canvas cemented over the edges of the last mentioned covering.
The whole is then suitably enclosed in an ordinary outer rubber covering.
For securing the tyre to the rim of the wheel, I have slots in such rim corres-
ponding to the aforesaid lugs, these latter enter into the said slots and are held
therein by bolts. Or in the case of divided or double wheels the said lugs could
be bolted in between the two sections of the wheel.
And in order that my said invention may be better understood I will now
proceed to describe the same with reference to the drawing accompanying this
specification, in which Fig. 1 shews a section of tyre and rim made in two
sections, Fig. 2 is an elevation of a small portion of said tyre, Fig. 3 shews a
section of a modification of said tyre applied to an ordinary rim, Fig. 4 is a
detached view hereinafter referred to.
The same letters denote the same parts in all the views.
a shews the outer covering, b the air chamber, the rim. The air tube b is
surrounded and protected by a leather cover, this cover is formed of a number
of pieces of the shape shewn at Fig. 4. The edges of these pieces are turned
slightly outwards, as shown at r, Figs. 1 and 3, so that the stitching which is
through these edges shall not form ridges upon the inner surface of the cover d¹.
The inner surface is consequently left perfectly smooth. The main seam of this
cover is at the top or outer side, as shown at r Figs. 1 and 3.
m shews strips
of leather forming tongues (placed at suitable intervals round the tyre) attached
to the leather cover at the top z, and passing round the said cover until they
meet at the bottom, or inside (a Fig. 1) where they are clamped between two
sections and of a wheel made in two parts, as shewn at Fig. 1. shews one
of the bolts employed for holding these two sections together. This leather
cover is enveloped in an outer rubber cover a which may be of the usual form.
The ends of the strips m pass between the edges of the outer cover.
In the modification shewn at Fig. 3. in which view for sake of clearness, the
outer cover is not shewn, the wheel is of the ordinary form-not in two sections
and the attachment is effected by means of screws or bolts passing through
the leather cover, strips m, cover and rime of the wheel, nuts being
screwed down on the projecting ends of the bolts p.
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
1. In pneumatic tyres, the employment of a covering composed of a number
of pieces, substantially as and for the purpose set forth.
2. In pneumatic tyres for motor cars and other heavy vehicles, the employ-
ment of tongues such as those shewn at in on the accompanying drawing for the
purpose set forth.

page_text: 3. Pneumatic tyres, constructed as shewn at Fig. 3 on the accompanying
drawings.
4. Pneumatic tyres composed of au air tube, surrounded by a leather cover d'
composed of a number of strips of the shape shewn at Fig. 4, (the edges of such
strips being turned slightly outwards, so that when stitched together they shall
not form ridges upon the inner surface of the cover d¹) provided with leather
strips m forming tongues, the said tongues being clamped between the divided
portions of the rim c.
