COMPLETE SPECIFICATION
Improvements in and relating to Pneumatic Tyres.
We, HERMAN ANTHONY FONTEINE, Harness Maker, of 10, Mary Street, Auburn,
in the County of Cayuga, and THOMAS SCHENCK KELLET, Insurance Bioker, of
87, Fourth Street, Troy, in the County of Reusselaer, both in the 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 ascei-
tained in and by the following statement
-
This invention consists of a tyre adapted particularly to bicycle wheels and
characterized by a rim having a number of pneumatic bulbs projecting outward
therefiom and serving as the tread of the tyre, the bulbs being in communication
with each other so that they may be inflated and deflated simultaneously
This specification is the disclosure of one form of my invention, while the claims
define the actual scope of the invention
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding paits
in all the views,
Figure 1 is a side elevation of the invention,
Figure 2 is a fragmentary longitudinal section of the tyre, and
Figure 3 is an irregular section on the line 3-3 of Figure 2.
The tyre consists in a metallic rim 4, to which the spokes 5 of the wheel are
attached The rim 4 18 provided at its outer surface with a series of annular
mbs 6 exteriorly threaded and respectively receiving the clamping rings 7 which
have inwardly projected or contracted portions at their outer edges serving to
hold the beads 8 that are formed at the base edges of the approximately semi-
spherical bulbs 9. By these means the bulbs 9 are respectively heimetically con-
nected with the ribs 6 The bulbs 9 are constructed in any desired manner, of
flexible material. The 11m 4 18 provided with a series of equidistant arc-shaped
enlargements 10 leading between the contiguous bulbs 9, and provided with
passages 11 which establish communication between the interiors of the bulbs
By these means the bulbs are all placed in communication with each other
nipple 12 18 in direct communication with one of the bulbs 9, and consequently
with the other bulbs through the medium of the passages 11 By means of this
nipple the tyre may be inflated and deflated
A
It will be seen that a continuous an passage is provided throughout the tyre,
thereby allowing the air to pass out gradually in case of the bursting of one of
the bulbs 9, enabling the rider to dismount before any accident resulting from
the bursting of the bulb could occur
It will also be seen that the bulbs 9 are independently removable, so that if one
of them should be punctured it can be removed and fitted with an interior skin
or film of fabric after which it can be replaced and the series of bulbs be again
inflated, when the internal pressure of compressed air will force the skin or film
against the inner walls of the punctured bulb and close the puncture.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same 18 to be performed, we declare that what we
claim 18.
1 A vehicle tyre having a 11m, a series of expausible bulbs, means for unde-
pendently securing the bulbs to the rim, and a series of passages formed in the
rim and connecting the bulbs with each other, one of said bulbs being in com-
munication with a nipple, whereby all the bulbs may be inflated, substantially as
described.
2 A vehicle tyre having a rim provided with a series of ridges or enlargements
each having a passage extending through it, and a series of inflated bulbs inde-
pendently secured to the said rum, the passages in the said ridges or enlargements
respectively connecting with adjacent bulbs, whereby the bulbs are all placed in
communication with each other, substantially as set forth
3 A vehicle tyre having a rim provided on its outer face with a series of annular
ribs, a clamping band screwing over each annular rib, and a series of inflatable
bulbs provided at their base edges with beads arranged to be held between the
respective ribs and clamping bands, substantially as specified
4. A vehicle tyre having a rum provided on its outer face with a series of annular
ribs exteriorly threaded, expansible bulbs provided at their base edges with beads,
clamping nings adapted to screw on the said annular 11bs and having inwardly
projected or contracted portions at their outer edges serving to hold the beads
against the said annular ribs, the said bulbs being in communication with each
other, substantially as set forth
5 A vehicle tyre provided with a im, a series of expansible bulbs, means for
securing said bulbs on the outer surface of the rim, the said rim being provided
on its inner face with a series of equidistant arc-shaped enlargements leading
between the contiguous bulbs, and each having a passage forming a communica-
tion between the interior of contiguous bulbs, respectively, substantially as
described
