PROVISIONAL SPECIFICATION.
Improvements in Wheels for Velocipedes and other Vehicles.
I. THOMAS WILSON ROBERTSON of 88 Alfred Terrace, Mountpottinger Road,
Belfast, in the County of Down, Ireland, Engineer do hereby declare the nature
of this invention to be as follows:-
My invention relates to improvements in wheels for velocipedes and other vehicles,
whereby perfectly noiseless running, and the absence of vibration is attained without
the use of india-rubber or other solid resilient substance or material.
In carrying my invention into effect, I employ a woven tube of wire which may
or may not be covered with cloth, rubber, or other suitable material, and attach the
same to the rim of the wheel to which it is adapted by any of the well-known
methods, thus forming a strong, light, and elastic tyre. I may vary this arrangement
by employing a half tube of woven wire, the edges of which are attached to the rim
of the wheel in such a manner as to present a convex surface in cross section which
is equally elastic and non-vibratory as the arrangement of the complete woven tubular
tyre first described.

COMPLETE SPECIFICATION.
Improvements in Wheels for Velocipedes and other Vehicles.
I, THOMAS WILSON ROBERTSON of 88 Alfred Terrace, Mountpottinger Road
Belfast, in the County of Down, Ireland, 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 :-
My invention relates to improvements in wheels for velocipedes and other vehicles
and by its application perfectly noiseless running is ensured and the absence of vibration
is attained without the use of india rubber or other solid resilient substance or
material.
For the purpose of affording a clear description of my invention I have appended
the accompanying sheet of drawings and have used throughout similar letters to
indicate corresponding parts.
Fig. 1 is a side elevation of part of the rim of a velocipede wheel fitted with my
elastic woven wire tubular tyre which forms the salient feature of my invention.
Fig. 2 is an enlarged sectional view of same, shewing the method adopted by me, in
certain cases, of enclosing or covering the aforesaid tyre with a non-metallic substance.
Fig. 3 is a side elevation of part of a velocipede wheel similar to Fig. 1, the difference
being that in this case I make use of a semi-tubular elastic spring tyre as shewn by
Fig. which is an enlarged sectional view of Fig. 3.
In carrying out my invention I employ a woven tube A Figs. 1 and 2 made of
elastic wire, preferably steel, and woven in such a manner as to be continuous for
the whole of the length required, and by interweaving or otherwise joining the
ends of said tube a perfect annular elastic tube is formed, which I place within the
concave rim of a velocipede wheel and attach it thereto by any of the well known
methods in use for that purpose. The conformation of said tube corresponding to
the concavity of the rim a perfect seat is formed for about half the diameter of the
tube as shewn by Figs. 1 and 2. I may where desirable cover the said tube A with
cloth, india rubber or other suitable material B before fixing upon the wheel, so that

page_text: when in position upon the rim it would appear in cross section as illustrated
by Fig. 2. Or I may prepare the woven elastic wire in such a manner as to be semi-
tubular in cross section as shewn by the sectional view Fig. 4 and attach it by means
of metallic stitches to the rim D of the wheel as shewn by Figs. 3 and 4, suitable
holes having been previously made in the rim D for that purpose.
Or I may
weave the said semi-tubular elastic tyre A directly upon the rim of the wheel through
the before mentioned holes and I may cover the exposed surface of the semi tube
with the same material as adopted in the case previously explained and illustrated
by Fig. 2, in either of the methods cited the tyre presents the same convex wearing
surface when in position upon the wheel, and equally elastic and non-vibratory, and
equally applicable to wooden as metallic rimmed wheels.
I wish it understood that I may make use of either a tubular or semi-tubular
elastic woven wire tyre either covered or not as desired without departing from the
principle of my invention, and that although I have chosen to describe my invention
in connection with velocipede wheels, it is obvious that it is equally well adapted
.for use upon carriages and other light vehicles having wheels with concave rims.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
First In an improved wheel for velocipedes and other vehicles the construction
and use of an elastic woven wire tubular tyre A substantially as and for the purposes
herein set forth and shown by Figs. 1 and 2 in the accompanying drawings.
Second In an improved wheel for velocipedes and other vehicles the construction
and use of an elastic woven wire semi-tubular tyre A, woven into suitable holes in,
or fastened by metallic stitches C to, the rim D of the wheel substantially as berein
described and shewn by Figs. 3 and 4 in the accompanying drawings.
Third In an improved tyre for wheels of velocipedes and other vehicles the
construction and use of an elastic tyre A as set out in the two previous claims, covered
with india rubber or other suitable material B substantially as herein shewn and
described, reference being had to the accompanying drawings.
