PROVISIONAL SPECIFICATION.
A New or Improved Tyre for Cycles.
I, WILLIAM HENDERSON, of 23 Drury Street, Dublin, Ireland, Machinist, do
hereby declare the nature of this invention to be as follows:-
This invention has reference to a new or improved tyre of durable and efficient
construction for the purpose of obviating the inconvenience of vibration and
slipping.
My inproved tyre is composed of a solid casting of india-rubber consisting of
two bands an outer and inner one-both being connected by a continuous series
of bridges, or curved pieces, springing from the inner to the outer band-each
bridge forming its point or apex on the inner surface of the outer band.
Midway between these two bands, and also between the outer curve of each
bridge is introduced a web of the same thickness on its upper edge as the complete
tyre, and tapering to a fine thinness towards the base of each bridge.
As thus constructed the tyre may be applied to the rim of the ordinary wheel in
the usual manner.
It is obvious that a double band tyre of this nature will present a kind of open
framework, and will be found to afford considerable elasticity owing to the yielding
or springy character of the bridges, or curved supports occupying the annular space
between the two bands..

COMPLETE SPECIFICATION.
A New or Improved Tyre for Cycles.
I, WILLIAM HENDERSON, of 23 Drury Street, Dublin, Ireland, Machinist, 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 reference to a new or improved tyre of durable and efficient
construction for the purpose of obviating the inconvenience of vibration and
slipping.
My improved tyre may be composed of one or more solid castings of india-rubber,
or other suitable material, consisting of two concentric rings or bands--an outer
and inner one-both being connected by a continuous series of bridges, or curved
pieces, springing from the inner to the outer ring or band—each bridge forming its
point or apex on the inner surface of the outer ring or band; or this arrangement
may be reversed if found more convenient in practice, i.e. the bridges may spring
from the outer towards the inner band.
Between these two concentric rings or bands, and also between the outer curve
of each bridge is introduced a web or band or other connection tapering to a fine
thinness towards the base of each bridge.
As thus constructed the tyre may be applied to the rim of the ordinary wheel in
the usual manner.
It is obvious that a double ring or band tyre of this nature will present a kind of
open framework or series of perforations, and will be found to afford considerable
elasticity owing to the yielding or springy character of the bridges or curved
supports occupying the annular space between the two rings or bands

page_text: In order that my said invention may be more readily understood and carried into
practice, I will describe the drawings attached hereunto :-
Fig. 1, represents an elevation of an ordinary bicycle wheel, with my improved
tyre attached thereto; and
Fig. 2, an enlarged transverse section of web connection on line x Fig. 1.
a, a, are the outer and inner concentric rings or bands; and b, the bridges or
curved pieces, the whole being composed of one solid casting of india-rubber or
other suitable material as already described; or if found more convenient either in
the process of manufacture, or in the practical working of the invention, the
concentric rings or bands may be separate and joined together by the bridges or
curved supports, or they may be connected by a series of perforations formed by
rings, ovals, diamonds, or squares of india-rubber or other suitable material--the
principle of the invention being always constant; that is, a tyre of india-rubber or
other suitable material, composed of one solid casting, or several separate castings,
and formed of a suitable transverse thickness, and a certain depth in its vertical
plane so as to admit of the centre along its length being transversely perforated
by any of the means just described.
The bridges or curved pieces may be connected by a web c, (Fig. 2) or by a
strap or band, or other suitable connection-the object being to strengthen and
impart additional elasticity to the tyre.
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 :-
First. The use and application of a tyre for cycle wheels composed of a band of
india-rubber or other suitable material of one solid casting as herein described and
illustrated, or cast in several parts and afterwards built up as herein described, in
the manner substantially as specified and set forth.
Second. The use and application of a tyre for cycle wheels, composed of a band
of india-rubber or other suitable material, and perforated along its entire length
by a series of bridges as herein specified, or otherwise perforated by any suitably
shaped openings, the object being to impart lightness, strength, and elasticity to the
tyre, as in the manner herein substantially described and set forth.
