We, WALTER SWAIN of 177 Belmont Road, Land Agent, and WILLIAM
PHILIPSON of Holland Street Iron Works, Engineer, both of Astley Bridge near
Bolton in the County of Lancaster, do hereby declare the nature of our said
invention to be as follows:-
:-
This invention relates to improvements in the construction of tyres of wheels for
bicycles, tricycles, and other road vehicles in a novel and unique manner and is
designed to remove the defects at present existing in pneumatic and other tyres
inflated by means of air, gas, or liquids under pressure. It is well known that
inflated tyres are liable to become damaged and cut when travelling over rough
roads, consequently are uncertain in their action, which is a source of great
aunoyance and trouble. Our invention is intended to remove this defect and make.
them more certain in their action. This we accomplish by enclosing the inflated
portion of the tyre with a steel or other metallic tape of suitable width to facilitate
wrapping in a spiral form and to allow of the same giving and taking under all
conditions. In forming the spiral tape round the inflated portion of the tyre each
layer overlaps the other, and after the entire ring has been covered the ends are
secured in any convenient manner. If desired the inflated portion of the tyre may
be bound longitudinally with a steel or other metallic tape before the spiral one is
placed thereon, thereby making the inflated portion of the tyre impervious to sharp
instruments, tacks, nails, and other analogous articles or substances met with on
roads when travelling. In lieu of the spiral tape we may employ a pliable metallic
cover composed of steel or other metallic strips or tapes with overlapping and butt
joints; the latter being placed either inside or outside the iron portion of the tyre.
The butt joints can be covered with metallic plates in any convenient manner.
After the inflated portion of the tyre has been encased in our improved manner and
secured thereon the whole is encased in canvas or other suitable material or
substance.

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 relates to improvements in the construction of tyres of wheels for

suitable width to facilitate wrapping in a spiral form and to allow of the same
giving and taking under all. conditions. In forming the spiral tape round the
inflated portion of the tyre each layer overlaps the other, and after the entire ring
has been covered the ends are secured in any convenient manner. If desired the
inflated portion of the tyre may be bound longitudinally with a steel or other
metallic tape before the spiral one is placed thereon, thereby making the inflated
portion of the tyre impervious to sharp instruments, tacks, nails, and other
analogous articles or substances met with on roads when travelling. In lieu of the
spiral tape we may employ a pliable metallic cover composed of steel or other
metallic strips or tapes with overlapping and butt-joints; the latter being placed
either inside or outside the iron portion of the tyre. The butt-joints can be
covered with metallic plates in any convenient manner. After the inflated portion
of the tyre has been encased in our improved manner and secured thereon the
whole is encased in canvas or other suitable material or substance.

inflatable tyre encased with the pliable metallic cover shown in Fig. 9.
F is the rim of the wheel; H, H, are portions of some of the spokes, and I is the
india-rubber or other tube inflatable by air, gas, or liquids. We carry our
invention into effect in the following manner :-The india-rubber or other tube I is
first inflated, then covered with the canvas, flannel, leather, or other suitable
substance K, which may be secured thereon by cement, stitching, india-rubber or
other solution. Over the canvas or other substance K is wrapped in a spiral form
the steel or other metallic tape L. After the tube I has been wrapped with the
steel or metallic tape L the joints of same are covered in a spiral form by the steel
or metallic tape M as shown in Fig. 1, thus causing each layer to overlap the other.
Before wrapping the canvas K with the steel or other metallic tape L it may be
coated with cement, india-rubber, or other solution to allow of the said tape being
thoroughly bedded. After the india-rubber or other tube I has been encased in
the metallic tapes L and M, the latter are covered by one or more layers of canvas
or other material N. If desired the metallic tape L may be provided with the
projections to ensure of the tape M maintaining its position thereon. After the
entire ring or tube I has been covered by the tapes L and M the ends are secured
together by means of a clip, soldering, rivets, or other suitable material, or in any
other convenient manner. If desired this invention may also be carried out as
follows: The canvas K is in the form of a tube which we place on a mandrel, and
then coat the outside with solution after which it is wrapped in a spiral form with
steel or other metallic tape L. Over this layer of tape we place a layer of linen
or other suitable material and coat with solution and wrap again with another layer
of steel or other metallic tape M, and cover the whole with linen or canvas. After
the mandrel has been withdrawn the tube K is ready to receive the inflatable
tube I.
In another modification of our invention we employ only one metallic tape as

page_text: shown in Fig. 5. In this arrangement the steel or metallic tape L is wrapped
spirally round the inflated tube I in such a manner that each half overlaps the
other, thus making a metallic casing of double strength with one layer or band of
metallic tape.
In lieu of the spiral tape or tapes we may employ a pliable metallic cover to
encase the inflated tube I. In this arrangement to the canvas K are secured, by
cement, india-rubber or other solution, the steel or other metallic strips or tapes
with over-lapping and butt-joints as shown in Figs. 9, 10, and 11. The steel or
other metallic strips or tapes are cut into lengths sufficiently long to encircle the
inflated tube I, and are disposed on the canvas K so as to allow of the joints being
covered with the over-lapping steel or other metallic strips or tapes S. After the
metallic cover has been constructed in this manner it is bent round the inflated
tube I until the ends W and X meet as shown in Fig. 12; the butt-joint T being
covered with the metallic plate Y secured in any convenient manner. This metallic
cover may be covered with one or more layers of canvas or other material to
protect the same.
To further increase the efficiency of our invention the india-rubber or other
inflatable tube I after being encased in canvas may be bound longitudinally on the
tread or outer periphery with the steel or other metallic tape P before being
wrapped spirally as shown in Figs. 7 and 8, thereby making the inflated tube I
doubly secure and impervious to sharp instruments, tacks, nails, and other analogous
articles or substances met with on roads when travelling. The steel or other
metallic tape P can be of any desired width and placed upon the tread portion.
bearing on the road.
In each modification of our invention the steel or other metallic tape or tapes
may be silver-plated, coppered, tinned, or coated with anti-corrosive or other paint,
cement, or other substance or liquid that will protect the same from damp and
prevent deterioration by corrosion.
An important feature of this invention is that the steel or other metallic tape or
tapes will give and take under all conditions of working, at the same time
maintaining a resilient action.
After the inflatable tyre has been constructed in the form hereinbefore set forth
it is sprung on the rim F of the wheel and secured and covered in the ordinary
manner.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
1. Wrapping or enclosing an inflatable tyre with steel or other metallic tape or
tapes in a spiral form to break joints, for the purpose specified.
2. In an inflatable tyre the use of a pliable cover composed of steel or other
metallic strips or tapes arranged to break joints, for the purpose specified.
3. In an inflatable tyre wrapped or enclosed with steel or other metallic tape or
tapes in a spiral form or by a pliable metallic cover composed of steel or other
metallic strips or tapes the use of a steel or other metallic tape placed under same
and bound round the outer periphery of the inflated tyre or tube for the purpose
specified.
4. The general arrangements, constructions, and combinations of parts composing
our improved means for enclosing or protecting inflatable tyres for bicycles,
tricycles, and other road vehicles, such as, carriages, and the like, as herein before:
described and as illustrated in the annexed drawings.
