I, CHARLES COLLINS of Berkswell Coventry in the County of Warwick do
hereby declare the nature of my said invention to be as follows:-
My invention has for its object improvements in tyres for wheels which are
intended to supersede or be a substitute for pneumatic tyres, that is to say by this
invention a certain amount of flexibility and resiliency is obtained without the
fear of the consequences of puncture to which pneumatic tyres are liable.
new tyre is composed of a coil or spiral of metal such as steel and of either
round wire or of a flat or thin section. A coil of such metal is made and is then
embedded in india rubber or canvas or other textile material and rubber so that
when the tyre is made up the spiral forms a part of the substance of the tyre.
Such a length of spiral made up in a tyre is formed into the necessary diameter
for the wheel and sprung into the required position where it is permanently held.
I may however simply cover the coil of metal with a rubber tyre internally lined
with canvas or textile material and this covering may only have the rubber coating
on the tread side. Such tyres may be made to suit any wheel.

I, CHARLES COLLINS, of Berkswell, Coventry, in the County of Warwick, do
hereby declare the nature of my said 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 has for its object improvements, in tyres for wheels which are
intended to supersede or be a substitute for pneumatic tyres, that is to say by this
invention a certain amount of flexibility and resiliency is obtained without the

on the tread side. Such tyres may be made to suit any wheel.
In order that my invention may be more clearly understood and easily. carried
into practical effect I have appended hereunto a double sized sheet of drawings
upon which I have illustrated examples of my improved tyre.
Figure 1 is a cross sectional perspective view of a portion of my tyre secured to
the rim R.
Figure 2 is a similar view to Figure I shewing the inner rubber tube in which
fin spring Sis embedded..
Figure 3 is a cross sectional perspective view of a portion of my tyre with a part
of the side broken away.
Figure 4 is a similar view to Figure 2 shewing a round instead of a flat spring.
In carrying my invention into practice I take the flat coiled or spiral spring S
which is first covered with cotton or other equivalent material st and then embedded
or moulded in the rubber tube A as clearly shewn at Figure 3. This tube with
its spring is then inserted into the rubber tube B. which is preferably lined with
canvas, 6 and the portion which forms the tread of. the tyre may be made thicker
as shewn, thus forming the complete tyre which may be sprung into the rim R
and held permanently by cement or other means.
At Figure 4 I have shewn a round spring S2 instead of a flat one enbedded or
moulded in the rubber tube A which is afterwards inserted in the outer tube B as
herein before described.
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:
CLAIMS.
First: The improvements in tyres for wheels consisting essentially of a round
or flat helical or coiled spring moulded with or embedded in a rubber tube such
as A and inserted in an outer tube such as B in the manner and for the purpose
substantially as herein before described and as shown upon the accompanying sheet
of drawings.
1.
Second-Forming tyres for velocipede and other vehicle wheels by moulding or
embedding a round or flat coiled or spiral spring which has been previously
covered with cotton or equivalent material in a rubber tube which tube is after-
wards enclosed in an outer rubber or rubber and canvas tube in the manner
substantially as hereinbefore described and as shown upon the accompanying sheet
of drawings.
