Commercial Agent, both of the Village of Fairport, in the County of Monroe and
State of New York, United States of America, 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 improvement relates to pneumatic tires for bicycles and other vehicles, and
consists of a flexible band or tube provided with a series of overlapping plates.
arranged as hereinafter described and claimed.
In the drawings-
Figure 1, is a cross section of the pneumatic tire and the rim of the wheel,
showing the improvement.
Fig. 2, is a plan view of a portion of the metallic surface which is interposed
between the tube and outer covering, the same being shown in this figure as spread
out in a flat form.
Fig. 3 is a vertical section showing one of the metallic plates attached to the
supporting lining.
Fig. 4 is a side elevation of one of the clamps.
This improvement is applicable to bicycle wheels and all wheels of a similar
nature that are provided with pneumatic tires.
The object is to prevent puncturing of the tire in running over stones and other
sharp projections.
A indicates the rim of the wheel and B the pneumatic tire, which, in themselves,
are of ordinary form and construction.
C is the metallic surface, in which a series of small metallic plates a, a, are laid
so as to overlap on all sides, making a continuous surface, and secured by rivets b, b,
to an under lining c. This is laid over the tread portion of the tire, as shown in
Fig. 1, and is then covered by the ordinary outer covering d. Each of these plates.
yields under action and has free motion, and the tire retains its usual elasticity.
The plates may be made of any suitable metal, but aluminium is preferable owing
to its extreme lightness. The lining c is not indispensable, as the metallic covering
can be attached to the inner side of the outer covering d, and it may be attached
by other means than riveting. The plates are arranged in parallel rows as shown
in Fig. 2, the first layer being on the middle line of the tire and the other rows on
either side of same. The plates are also attached in their center, by which free
action is attained.
F is a clamp for holding the outer covering d in contact with the rim of the
wheel. It is in the form of a circular flange to fit the rim, and is attached thereto
by screws g, g.
The edges of the outer covering d are fitted between the clamp
and the rim, and the clamp is then tightened by turning up the screws.
The clamp
is preferably made in sections or segments, by which means, when repairs are
required, a portion only of the outer covering may be laid open to make the repairs
at any particular point.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is-
1. In a pneumatic tire, a flexible band or tube having a series of overlapping
plates on the medial line of said band or tube, and other series of plates arranged

page_text: 2. A flexible band or tube having a series of overlapping plates arranged in
parallel rows, each plate being centrally and separately secured to the band or tube,
as and for the purpose specified.
