PROVISIONAL SPECIFICATION.
Improvements in or relating to Elastic Tyres for Cycles and
other Vehicles.
1 JOHN GREEN No. 2 Waterloo Road S. Wolverhampton, Surgeon &c., do hereby
declare the nature of this invention to be as follows:-
Preferably a wheel with a flat rim & slightly raised margins on which blocks of
wood, rubber, cork, or any substance capable of bearing the weight are placed
equidistant all round; upon these blocks a band "or several small bands of metal
or rings of piano wire" is placed tightly, to keep the blocks in position & bear
the weight, which will impinge from another superimposed band & blocks.
second layer of blocks is placed equidistant on the first band in the interspaces above
the first blocks, and upon the second layer of blocks another similar band or bands
is stretched tightly, on this second band is placed a rubber band which will come
in contact with the ground, & protect the 2nd band; from this rubber band, side
flaps are prolonged to the rim of wheel to incase the tire & protect from weather.
The band or bands should be metallic, or woven fabric, e. canvas, webbing,
"faced with rubber" or leather, catgut & vulcanized fibre, or a combination of these
materials.
The spaces between the second layer of blocks may have small rubber blocks to
preserve contour of tyre.
COMPLETE SPECIFICATION.
Improvements in or relating to Elastic Tyres for Cycles and
other Vehicles.
I, JOHN GREEN Surgeon &c. 2 Waterloo Road S. Wolverhampton 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:-
Preferably a wheel with a flat rim and slightly raised margins, on which blocks or
supports of wood, rubber and corrugated steel strips, as illustrated on Plate 3, or any
other substance capable of bearing the weight to be carried, are placed, equidistant
round the rim.
As shewn in Plate 1, the supports may vary in diameter for the various tiers.
Upon these supports, which are slotted, a band. or bands, of narrow spring steel are
placed in the slot or slots, tightly: the proper tension is obtained by the length or

page_text: lengths of band or bands and the number of supports placed between the band
or bands, and the rim.
The rings or bands may be made of other materials, as woven fabrics, canvas,
webbing or leather, cat-gut and vulcanized fibre, or these substances may be used
in conjunction with the steel bands or steel wires.
The ends of steel bands or rings may be rivetted, welded or brazed together.
The first band or series of bands being secured, a second hand or series of bands,
a little larger than the first, is used, and supports of wood or other substances
placed between the first and second bands or series of bands, for the support of the
fatter, equidistant apart, in the interspaces above the first layer of supports and this
process may be repeated ad libitum, which gives more elasticity and is pursued to
three tiers as shewn on Plate 1. The steel band or bands being of increased diameter
to allow of the necessary supports being placed beneath them and upon the second
band or series of bands."
Upon the outer band or bands, whether the second or third tier, a belt of leather
or rubber is placed, to come in contact with the ground, protecting the bands and
giving smoothness when running. Beneath the leather or rubber, canvas or other
suitable material is used, and prolonged round rim of wheel, and secured in
place by lacing or cement. This covering encases the tyre and excludes wet
and dirt.
The leather may be stitched and cemented to the canvas, and the rubber
vulcanized or cemented to it. In this way the canvas, or the leather and rubber can
be secured to the band or bands by steel wires, and thus keep the tyre and outer
covering in proper position. The supports are bored longitudinally just large
enough to allow of steel wires to be passed through then, in opposite directions,
and inade tight; the ends of the wires are secured to a spoke or passed through a
hole in the rim and twisted round a stay.
The object of these wires is to keep the wood supports in position, but in the
case of the corrugated steel strip support, it is secured in position by steel wire
passed transversely round the steel band or bands and support, at points of contact
and twisted securely. The corrugated strip support is made continuous, in circular
form, of the necessary diameter to fit in position, the ends being brazed or rivetted
together, and spring into position upon rim or upon band or bands.
Having now described some of the materials and their uses in constructing the said
tyre I will now proceed to illustrate the same as depicted in the various drawings, to
make the invention more clearly understood.
Plate 1, Figure 1, is a plan of the tyre with the outer covering removed, shewing
three narrow steel bands and their supports. The dotted lines represent the wires
passing through supports. A, is rim of wheel. B, wires having passed through
supports, retaining supports in position. C, steel bands. D, supports.

supports.

apports to band or bands.
The figures below represent Figures 1 and 2, in situ.
Plate 4, shews outer coverings of tyres applicable to tyres shewn upon Plates 1 and 2.
Having now particularly described, and ascertained the nature of my said
nvention, and in what manner the same is to be performed, I declare that
what I claim, is.
1. Improvements in or relating to elastic tyres for cycles and other vehicles.
2. The use of one or more narrow bands placed parallel to each other, and
several tiers, superimposed, as shewn on Plate 1, with suitable materials,
substantially as described, Plate 1.
3. The use of one broad band, on which one tier or more is superimposed, with
suitable materials, substantially as described, Plate 2.
4. The use of corrugated steel strips, in lieu of the wood supports and other
substances for carrying the steel band or bands, substantially as described,
Plate 3.
5. Materials arranged for use in producing elastic tyres for cycles and other
vehicles, substantially as described, and shewn according to different modifications, by
the drawings herewith.
