PROVISIONAL SPECIFICATION.
Improved Tyre for the Wheels of Carts, Carriages, Cycles, and other
Vehicles.
I, ARCHIBALD BINNIE ALLAN of 32 Moray Place, Strathbungo, Glasgow, in
the County of Renfrew, North Britain, Civil Engineer, do hereby declare the
nature of this invention to be as follows :—
This invention relates to an improved tyre for deadening the noise of the wheels
of carts, carriages, cycles and other vehicles and for rendering their travel more
smooth.
My invention consists of encircling the wheels with ropes or bands of iron, steel
or other metal wires or rods, twisted, spun, plaited or woven together. Or the
wire may be simply wound round the wheel in one or more windings.
The ropes, bands or wire windings above mentioned may be applied to the wheels
either as forming the tyre or as an adjunct of the tyre.

COMPLETE SPECIFICATION.
Improved Tyre for the Wheels of Carts, Carriages, Cycles, and other
Vehicles.
I, ARCHIBALD BINNIE ALLAN of 32, Moray Place, Strathbungo, Glasgow, in
the County of Lanark, (formerly in the County of Renfrew), North Britain, Civil
Engineer, 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 relates to an improved tyre for the wheels of carts, carriages,
cycles, and other vehicles and has for its object to deaden the noise of the wheels
of carts, carriages, cycles, and other vehicles and to render their travel more
smooth.
My invention consists in forming the tyre of the wheel, or in fitting it with,
ropes, bands, or other fabrications of wires, rods, ribbons, or filaments of iron,
steel, or other metal twisted, spun, plaited, woven, or otherwise.combined
together.
The method of fabrication will be modified to suit the weight of the vehicle, the
load it carries, the speed at which it travels, and the purpose for which it is used.
Where great smoothness and quietness is required the fabrication of the wires or
filaments will be such as will best develope their resilence, a cellular or tubular
construction will in many cases be found most suitable and when it is adopted the
accumulation of snow, inud, or dirt may be avoided by filling the voids with cork
or other light non-resisting or elastic material.
When the form of the fabrication adopted is such as will make the combination
of wires or filaments sufficiently pliable the fabric may be wound round. the tyre
either transversely or longitudinally: and when the fabric is too rigid to admit of
this being done then it may be constructed either as a whole or in sections with a
curvature to suit the wheel.
But in order that my said invention may be more readily understood and easily
carried into effect I will proceed to describe a few examples of the application of
the same with reference to the accompanying drawings.

page_text: Figures 1, 2 and 3 are respectively, side view, edge view, and cross section of a
light wheel constructed according to my present invention.
Figures 4, 5 and 6 are part similar views of an ordinary wooden wheel with my
improvements attached.
And Figures 7, 8, and 9 are part similar views of a modification of same.
Referring to Figures 1, 2, and 3 of the drawings which illustrate a light wheel
suitable for a cycle or other light vehicle, I form the fabric of wires A as the tyre
of the wheel which is of tubular construction, though not continuously so as the
two approximate selvages are turned out to form two flanges a which are inserted
between two flanged or angled rings B of thin sheet metal to which they
are fastened by rivets or bolts c which also pass through eyes in the ends of the
spokes C of the wheel.
The wire tyre is preferably woven together in one piece though it may be joined
by lacing the two ends together with wire as at a and afterwards soldering the
joint or the two ends of the tyre may be brazed or otherwise connected to each
other; the said wires after being woven are preferably galvanized. Experience
will demonstrate what gauge of wire will best suit each type of vehicle but it may
be found most satisfactory to use thin wire and to strengthen the tube with internal
staying. A form of staying is shown on the drawings this consists of a wire D
passing from side to side of the tube in a zig-zag course and soldered to the wire
cloth forming the tubular tyre. The action of the said staying prevents the
collapse of the tube due to its sides bulging from the vertical pressure of the load.
It will probably prove advantageous to attach a narrow strip or band of wire
cloth E to the tyre around its circumference, which can be renewed from time to
time as it is worn out thus saving the wear and tear of the tyre. When the mesh
of the tyre is small, snow, mud and such like may be excluded by dipping the tyre
in thick varnish or lacquer.
A construction somewhat similar to the foregoing may be effected by winding a
single wire spirally around a cylindrical rod after which the tube of wound wire is
removed from the rod and curved to the required circle and the two ends suitably
united together. The tyre thus formed may be stretched and so put on to the
wheel the felloe of which being hollowed to receive it. The spring of the wire
would probably suffice to keep this tyre in its place but if not it may be fastened
in various ways. There is an objection to single wire constructions inasmuch as
fracture at any one point undoes the whole, so that this particular form of wire
tyre may with advantage, after it is put on, be laced longitudinally with wire
preferably soldered to it at all points of contact. Or if desired the said wire tyre
may be attached to the felloe with wires which would prevent a single fracture
causing the tyre to become undone.
In applying my invention to an ordinary wooden wheel I form the iron tyre F of
the wheel with a groove or recess into which the one end of a strip of wire cloth A
is fastened with a flat headed screw nail or otherwise. The strip or band of wire
cloth A is then with a slight strain regularly passed round and round the wheel
until the wire cloth or tyre A stands about half an inch or as much more as may
be necessary or beneficial above the iron tyre F. Each layer of cloth is tied at
frequent intervals to the layer below it with short pieces of wire the ends of which
are brought up, twisted together, and soldered down. As in the case last described
the wear and tear of the tyre may be prevented by providing the wire tyre A with
a single strip or band of wire cloth E.
As a modification of the foregoing, I may as shown in Figures 7, 8 and 9 fit the
wire tyre A to an ordinary wheel as at present in use without altering or preparing
the wheel specially. In this case I form the tyre A of wire cloth having an
internal tube G formed in it, the two folds of cloth are laced together with wire
where they touch as at g and the selvages or flaps are curved back so as to lie
against the sides of the wooden felloe H to which they are secured by means of
flat metal rings J and screw nails. The metal rings J should be broad enough to
cover the iron tyre and so support the wire tyre A and prevent it bulging. In

page_text: this case the tyre A may also be provided with a strip or band of wire cloth E
fixed to its bearing part. This particular form of tyre may be formed in short
sections and laced together at the joinings by wire.
In cases where the wire fabric tyre A does not actually form part of the wheel
there will probably be a little friction between the iron tyre F and the wire tyre A
and to prevent the wearing of the wires next the iron tyre I may interpose between
the said tyres a strip or band of canvas or other suitable material dipped in tar
or oil.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
In cart, carriage, cycle, and other vehicle wheels, the employment of tyres of
ropes, bands, or other fabrications of wires and the like, substantially as and for
the purposes hereinbefore described and shown in the accompanying drawings.
