Improvements in Pneumatic Tires and in Means for Securing the
same to the Rims of Wheels.
A communication from abroad by HIPPOLYTE JOSEPH LA FORCE, of Toronto, in
the Dominion of Canada, Shoemaker.
I, REGINALD WILLIAM JAMES of 1, Queen Victoria Street, in the City of
London, Civil Engineer, 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 :-
The invention relates to improvements on what are commonly known as
pneumatic tires. Such a tire consists of an inflated rubber tube fitted around the
felloe of the wheel, and the object of my present invention is to provide simple
means for connecting it to the felloe in such a manner that in the event of the
tire being damaged it can be easily detached, repaired and replaced on the felloe
in a very short period and without any special skill being required, and it consists,
essentially, of two strips attached to the outer canvas cover fitted into a properly
formed recess made around the periphery of the felloe, substantially as hereinafter
more particularly explained.
Figure 1, is a perspective sectional view of a felloe provided with my improved
tire.
In the drawings, A, is a rubber tube covered as usual with canvas.
B, is the outer canvas covering, to each edge of which is attached a strip, C,
made of rubber or other suitable material.
On each side of the felloe, D, a lip, a, is shaped to form a recess into which the
strip, C, will fit. The other edges of the strips butt against each other, as shown in the
drawing and serve to retain the outer edges of the strips C in the recesses formed for
them in the felloe D.
Before the tube A, is inflated, it is placed on the felloe and the canvas cover, B,
shaped around it. The strips, C, are inserted in the recess in the felloe D. When
the tube, A, is inflated, the cover, B, will naturally expand, forcing the outer edge
of the strips, C, under the lips, a, which thereby secure the inflated tire to its
felloe. It will of course be understood that the canvas cover, B, has a rubber
covering, E, securely cemented to it, the edges of the said covering extending over
the lips a. As these lips are nicely rounded off, the rubber or canvas coming
into contact with them. will not in any way be injured. From this description, it
will be seen that my improved tire can be readily removed and replaced, should
it be necessary to repair the said tire.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I would have it understood
that I make no general claim to the use of recesses in the felloe into which projections

page_text: from the cover or attached to the cover are made to fit but my claim is limited to cases in
which the special construction is used which is shown in the drawings in which the inner
edges of the strips butt against each other and thus serve to retain the outer edges in the
recesses in the felloe formed to receive them. But subject to the above disclaiming note
I declare that what I claim is :-
1. In combination with a rubber tire, a covering provided with a strip attached
to the edges of the said covering and fitted into a recess formed in the felloe of the
wheel, substantially as and for the purpose specified.
2. In combination with a rubber tire, a cover B, having a strip, C, fixed to each
edge thereof to fit under the lips, a, formed around the felloe, D, substantially as
and for the purpose specified.
