PROVISIONAL SPECIFICATION.
Improvements relating to Pneumatic Tyres.
I, WILLIAM FLETCHER, of Medical Hall, Bath Street, Ilkeston, Derby,
Wholesale Druggist, Wine, Spirit and Ale Merchant, and Mineral Water
Manufacturer and Bottler, do hereby declare the nature of this invention to be as
follows:-
My present invention has for its object to provide means whereby the inner air
(or inflation) tube of a pneumatic tyre of a cycle or other wheeled vehicle, is:
effectually safeguarded against punctures, and so as to ensure that when travelling
over rough or uneven surfaces, even though the outer covering in contact with the
ground should become pierced, it will be impossible for the obstructing object
(whether a piece of glass, jagged metal or other substance or material), to pierce
or puncture the inner inflated air tube.
Now in accordance with my invention I place between the inner inflated tube-
and the outer covering of the tyre a protective band or hoop, composed of any
convenient number of segments of sheet aluminium (preferably) steel, or other
suitable metal or material.
These segments are joined together by overlapping their ends and placing around
same india rubber or like bands. A suitable cushioning may if desired be placed.
between each overlapping portion of the segments.
By constructing the protective band or hoop in the foregoing manner, the speed'
of the tyre is not deteriorated, as the protective band will expand with the inner
air tube during the process of inflation, thus allowing the tyre to be inflated to its..
fullest extent.

in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-

puncture the inner inflated air tube.
Now in accordance with my invention I place between the inner inflated tube
and the outer covering of the tyre, a protective band or hoop, composed of any
convenient number of segments of sheet aluminium (preferably), steel or other
suitable metal or material.
These segments are joined together by overlapping same, and placing around
same, within suitable slots, formed at their ends, india rubber or like bands.
And in order that my invention may the better be understood I have appended
the accompanying sheet of drawings in which
Figure 1 represents a plan view of a portion of my protective band showing the
segments joined together at their outer ends.
Figure 2 is a detached plan of one of the segments employed when constructing
the band as shown in Figure 1.
Figure 3 is a similar view to Figure 1 showing the segments joined together at
their top and bottom ends; and,
Figure 4 is a similar view to Figure 2 of one of the segments employed when
constructing the band as shown in Figure 3.
Referring to the drawings a is the segments employed, which, as herein before
stated may be composed of any suitable metal or material, and provided with slots
such as b, into which latter are inserted india rubber or like bands c for securely
holding the segments a together, when same are placed overlapping, either in the
formation as shown Figure 1 or as shown in Figure 3 of the accompanying sheet
of drawings.
A suitable cushioning may if desired be placed between each overlapping portion
of-the-segments.
By constructing the protecting band or hoop in the foregoing manner, the speed
of the tyre is not deteriorated as the protective band will expand with the inner
air tube during the process of inflation, thus allowing the tyre to be inflated to its
fullest extent.
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 :-
In rendering pneumatic tyres puncture proof the employment of the protective
band or hoop, substantially as herein described and shown in the accompanying
sheet of drawings.
