Improvements in Elastic Tyres for the Wheels of Cycles and other
Vehicles.
I, WILLIAM CHARLES HUGHES, of Brewster House, Mortimer Road, Kingsland,
London, N.E., Manufacturing Optician, 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 :-
My invention relates to improvements in elastic tyres for the wheels of bicycles,
tricycles, motor-cars, and other manual and mechanically propelled vehicles, and has
for its object to construct a tyre possessing the same elasticity, flexibility, and
resiliency as that of a pneumatic tyre, without the necessity of inflation, and the
consequent inconveniences arising from punctures of the tube or chamber or chambers
so inflated.
I attain the object and purpose of my invention by constructing of suitably
vulcanized rubber, or rubber composition, or other resilient material, an elastic tyre
having any desired number of suitably disposed internal longitudinal endless hollow
passages, channels or chambers, each separated from its neighbour or neighbours by
a thickness or substance of material, commensurate with the desired resiliency of the
tyre, governed by a consideration of the weight of the vehicle it is to carry, the
extent of vulcanization and other surroundings and conditions, and for the purposes
of my invention, and with due regard to the said conditions, the said passages
channels, or chambers, may be of any shape or configuration or combination of shapes
or contours which in practice may be found most suitable for the purposes the tyre
is intended to fulfil, and with this in view, the several sections shewn in the sheet of
drawings hereunto appended are intended to make clear the principle of my
invention, and are merely examples of some of the many forms, shapes, or
configurations the said passages may assume, and the many ways in which such
passages may be disposed about the cross sectional area of the tyre.
Referring to the accompanying drawings
Fig. 1 is a longitudinal central section of a tyre according to my invention, while
Fig. 2 is a cross section of the same and the wheel rim upon which it is mounted.
Figs. 3, 4, 5 and 6 are enlarged cross sectional views of such a tyre, illustrating
some of the many and various shapes the said passages or channels may take, and
the positions of same within the substance of the tyre.
In carrying my invention into effect I mould or otherwise produce from rubber,
rubber composition or other resilient material a tyre A, preferably circular or
thereabouts in cross section, or slightly widened or extended upon that surface
intended to be the tread of the wheel, as shewn by full outline at a Figs. 1, and 2,
and by dotted outline in Figs. 3, 4 and 5, and within the said tyre I provide, during
its manufacture, any number of longitudinal passages or channels B, which may be
suitably disposed all over the cross sectional area of the tyre, as shewn in the first
five views, or only half or partly over the said area as suggested by Fig. 6, and I
may form the said passages or channels perfectly circular in cross section as at
Figs. 1, 2, and 6, or of hexagonal, octagonal or otherwise polygonal in shape as at
Fig. 3, or of diamond shape as at Fig. 4, or any desired combination of such or other
shapes as suggested by Fig. 5.
