Improvements in and connected with Pneumatic Tyres.
I, FREDERICK LEACH, of the Angaston Hotel, Angaston, in the Province of South
Australia, Hotelkeeper, do hereby declare the nature of this invention to be as
follows:
This invention is designed to overcome the difficulties in the use of pneumatic
tyres arising from their liability to puncture.
It consists in the employment of a specially constructed sectional jointed metal
cover or band and is used either externally or internally in relation to the ordinary
cover.
The form of the sections and the manner in which they are connected together
gives the metal cover or band or play both sidewise and lengthwise and in such a
manner that the danger of cutting the rubber is entirely obviated.
My metal band or cover is formed of a sufficient number of thin plates or sections
of steel aluminium or other suitable metal or alloy.
Each plate or section is before being curved to the shape of the tyre approximately
square but preferably a little elongated. One end instead of being straight across
is provided with a bell headed tongue and near the other end of the plate is provided
a hole to receive the tongue of the next plate.
The tongue and the hole may be of various shapes but those which I prefer are
a tongue having a bell shaped or a circular head with a contracted bar connecting
it to the plate and a square hole whose sides are parallel with the sides of the plate.
The plate tongue and hole form the complete section and all the plates are the same.
The diameter of the head of the tongue is such that it can be inserted through the
diagonal diameter of the square hole and when turned into its straight position will
form a secure fastening whilst the joint as described will allow play both sidewise
and lengthwise.
The flat plates or sections after having been stamped or formed of the shape as
above described are then curved transversely to the form of the inflated tyre the
plates being of such size that when curved they fit a little more than half round the
tyre.
A sufficient number of plates or sections thus formed are by means of the tongue
and hole laced or joined together to form a covering for the pneumatic tyre of the
size desired. The tyre having been partially inflated my cover is then placed around
it and on the inflation being completed will fit neatly and tightly around the tube.
In the case of tyres having an inner tube and outer cover like the Dunlop "
my covering may be advantageously placed between the inner tube and the outer
cover or it may be placed entirely outside the usual cover.
When my cover is placed outside in order to prevent any slipping the plates are
roughened by corrugations or indentations as may be required.

I, FREDERICK LEACH, of the Angaston Hotel, Angaston, in the Province of South
Australia, Hotelkeeper, 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 is designed to overcome the difficulties in the use of pneumatic
tyres arising from their liability to puncture.
It consists in the employment of a specially constructed sectional jointed flexible
metal band which may be used either externally or internally in relation to the
ordinary cover.
The form of the sections and the manner in which they are connected together
gives the metal band an amount of play both sidewise and lengthwise and in such
a manner that the danger of cutting the rubber is entirely obviated.
My metal band is formed of a sufficient number of thin plates or sections of steel,
aluminium, or other suitable metal or alloy.
Each plate or section is before being curved to the shape of the tyre approximately
square but preferably a little elongated. One end instead of being straight across
is provided with a square-headed or bell-headed tongue and near the other end of
the plate is provided a hole to receive the tongue of the next plate.
In order that my invention may be clearly understood I will describe the same
with reference to the accompanying drawings, in which-
Figure 1 shows one of the flat plates or sections.
Figure 2 shows several joined together before being curved.
Figure 3 shows several joined together and curved as in use.
Figure 4 shows a portion of my metal band enclosed in a casing of flexible
material.
The metal plates or sections A are stamped of the shape shown in Fig. 1.
The tongue A consists of a square or a bell-shaped head with a contracted bar
connecting it to the plate and the hole A3 is square with its sides parallel with the
sides of the plate.
The greatest diagonal or diameter of the head of the tongue is such that it can be
inserted through the diagonal diameter of the square hole, and when turned into
its straight position a secure fastening will be effected whilst the joint as described
will allow play both sidewise and lengthwise.
'
The flat plates or sections after having been stamped or formed of the shape as
above described may be curved transversely to the form of the inflated tyre, the
plates being of such size that when curved they fit preferably a little more than
half round the tyre.
A sufficient number of plates or sections thus formed are by means of the tongue
and hole joined together to form a band for the pneumatic tyre of the size desired.
Should it be desired, the metal band may be enclosed within a casing of flexible
fabric. In this case I cut two strips of the casing fabric somewhat wider than
the plates and place them one of each side of the connected plates, the overlapping
edges being then connected by a suitable solution, such as glue, or by other means,
as shown in Fig. 4.
To apply my invention to a single tube tyre, the tyre is partially inflated and my
band is then placed around it and on the inflation being completed I fasten an
ordinary rubber slip over the band with solution.
In the case of tyres having an inner tube and outer cover, like the "Dunlop,"
my band may be advantageously placed between the inner tube and the outer
cover,

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is:-
1. The hereindescribed sectional jointed metal band preferably of steel formed of
a number of thin plates or sections each having a tongue and a hole the tongue of
one fitting into the hole of the next section thus forming a band flexible both
sidewise and lengthwise, as and for the purpose set forth.
2. A band for pneumatic tyres formed of metallic plates or sections, each plate
having a tongue consisting of a square or bell-shaped head with a contracted bar
connecting it to the plate, and a square hole, the sides of which are parallel with
the sides of the plate, as herein described and for the purpose set forth.
Dated this 14th day of February 1898.
