EBENEZER BUCHANAN STEEL, Tea Merchant, 13, Crichton Street, Dundee,
N.B., do hereby declare the nature of this invention to be as follows:-
This invention has for its purpose improvements in the pneumatic tyres of
bicycles, tricycles, autocars and other vehicles.
The principle of the invention is the dividing of the inner tube of pneumatic
tyres into seperate cells, or the outer tube may be filled with seperate detached
air cells in the form of balls or otherwise.
In the first mentioned method of applying the principle of my invention with
the pneumatic tyre tube divided into separate cells, each cell would have a valve,
either in the form of a flap or otherwise to allow of inflation of the cell and to
prevent the air leaving the cells again.
In the second mentioned method of filling the pneumatic tyre with separate
or detached air cells they may be in the form of hollow balls, or may be hollow
cylindrical or other form, each provided with a valve in the form of a flap or
otherwise, so that while the outer cover is being inflated the balls or other form of
cells would be also filled with compressed air. By the automatic closing of the
valve in each cell the air would be confined in these balls or other form of cells,
and would support the outer cover if it should be damaged by puncture or other-
wise, so that no repairs would be necessary for some time, or till reaching the end
of the journey..
These seperate balls or cells of whatever form may be smooth on surface, or
may have points, knobs, ribs, or grooves, or other arrangement for allowing the
air to pass along the tube.
Cushions may be placed between these seperate air cells for supporting the
parts of the walls of the outer cover between the balls or cells after the air has
escaped from the tube in the case of a puncture or other injury to the tyre.
These cushions may have ribs, grooves, knobs, or other corrugations on surface
to allow the compressed air to pass along the tube, and also to have a surface
suitable for supporting the parts of the outer tube that are between the air balls
or other form of cells.
Another application of the principle of my invention is to construct a tyre in
which only the separate balls or cells of whatever form, have compressed air, and
the outer tube or cover entirely supported by these cells and cushions without
inflating the outer tube or cover.
In order to facilitate the building of the pneumatic wheel, nets or bags could
be used to hold each ball or cell, with a simple attachment at opposite points for
joining together with the cushions between them, or otherwise so as to make up
a continuous length of balls and cushions like a rope for easier insertion into the
outer tube or cover.

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 has for its purpose improvements in the pneumatic tyres of
bicycles, tricycles, cars and other vehicles.
The principle of the invention is the dividing of the inner tube of pneumatic
tyres into separate cells, or the outer tube may be fitted with separate detached
air cells in the form of balls or otherwise, as shewn in the accompanying sheet of
drawings. In the first mentioned method of applying the principle of my inven-
tion with the pneumatic tyre tube divided into separate cells, each cell would have
a valve, either in the form of a flap or otherwise to allow of the inflation of the
cell and to prevent the air leaving the cell again.
In the second method of filling the pneumatic tyre with separate or detached
air cells, they may be in the form of hollow balls, or may be hollow cylindrical
or other form, each provided with a valve in-the form of a flap or otherwise, so
that while the outer cover is being inflated the balls or other form of cells would
be also filled with compressed air. By the automatic closing of the valve in each
cell, the air would be confined in these balls or other form of cells, and would
support the outer cover if it should be damaged by puncture or otherwise, so that
no repairs would be necessary for some time, or till reaching the end of the
journey.
These separate balls or cells of whatever form, may be smooth on surface, or
may have points, knobs, ribs, or grooves, or other arrangement for allowing the
air to pass along the tube.
Cushions may be placed between these separate air cells for supporting the parts
of the walls of the outer tube between the balls or cells after the air has escaped
from the tube in the case of a puncture or other injury to the tyre.
These
cushions may have ribs, grooves, knobs or other corrugations on surface to allow
compressed air to pass along the tube, and also to have a surface suitable for
supporting the parts of the outer tube that are between the air balls or other form
of cells.
Another application of the principle of my invention is to construct a tyre in
which only the separate balls or cells of whatever form, have compressed air, and
the outer tube or cover entirely supported by these cells and cushions without
inflating the outer tube or cover.
In order to facilitate the building of the pneumatic tyre, nets or bags could be
used to hold each ball or cell with a simple attachment at opposite points for
joining together with the cushions between them, or otherwise, so as to make up
a continuous length of balls and cushions like a rope for easier insertion into the
outer tube or cover.
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:
1st. The dividing of the pneumatic tube of tyres of wheels for bicycles and other
vehicles into cells, each cell provided with a valve to retain the compressed air
and to support the outer tube after it has been damaged by puncture or otherwise.
2nd. The filling of the pneumatic tube of tyres of wheels for bicycles and other

page_text: vehicles with detached cells in the form of balls or otherwise, and each provided
with a valve to retain the compressed air for supporting the outer tube after it
has been damaged by puncture or otherwise. Cushions to fill up the spaces
between these cells may or may not be used of any suitable device.
3rd. The filling of the pneumatic tube of tyres of wheels for bicycles and other
vehicles with separate cells in the form of balls or otherwise, filled with compressed
air, each with or without a valve, and these having cushions between them to form
with the cells the only support for the outer tube. The outer tube not being
inflated.
