PROVISIONAL SPECIFICATION.
Improvements in Rims and Elastic Tyres for Wheels.
I, GEORGE HENRY NEDDERMAN of 6 Tudor Street, Werneth Hall Road,
Oldham, in the County of Lancashire, Mechanic, do hereby declare the nature of
this invention to be as follows:-
Referring to the accompanying drawing which represents a section of the rim
and tyre made by a plane passing through the axis of the wheel, A is the rim of
metal or other strong material turned over at the edges so as to hook over the
projecting parts of the tyre B as shown. B is to be made of a suitable material,
preferably india rubber, which may be lined either on the exterior, or on the interior
as at C, or which may have insertions of a material such as canvas, leather, or a
harder kind of rubber to secure it against internal pressure of air, and for
strengthening purposes. I should if required place stitches through the tyre B
below and parallel to the edges of the rim A, or make the projections on B of a
harder material than the remaining part and fix them on, by sewing cementing or
otherwise.
By this arrangement I propose to attach the tyre B firmly to the rim A when
D an air tube in the interior is inflated by means of a suitable valve, and thus to
obtain a large amount of tyre area for cushioning purposes, whilst providing at the
same time for easy access to the interior when the air has escaped, or has been
allowed to escape from D.
Dated this 18th day of March 1891.
COMPLETE SPECIFICATION (AMENDED).
Improvements in Rims and Elastic Tyres for Wheels.
I, GEORGE HENRY NEDDERMAN of 6, Tudor Street, Werneth Hall Road,
Oldham, in the County of Lancashire, Mechanic, 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 :-
Referring to the accompanying drawing, which represents a section of the rim
and tyre made by a plane passing through the axis of the wheel, A is the rim of
metal or other strong material, turned over at the edges so as to hook over the
projecting parts of the tyre B as shown. B is to be made of a suitable material,
preferably india-rubber, which may be lined, either on the exterior or on the interior
as at C, or which may have insertions of a material such as canvas, leather, or a harder
kind of rubber to secure it against internal pressure of air and for strengthening
purposes. I should if required place stitches through the tyre B below and parallel
to the edges of the rim A, or make the projections on B of a harder material than
the remaining part and fix them on by sewing, cementing or otherwise.
[Prins Rd I
By this

page_text: arrangement I propose to attach the tyre B firmly to the rim A when an air tube D,
in the interior, is inflated by means of a suitable valve. Furthermore, I propose to
seenre the edges of B (assuming C in the drawing to form a portion of B)-down
against the rim by laying over them a band, wire or cord E which passes-round,
and then through the rim, an aperture or apertures being suitably placed for the
purpose of passing one or both ends to the outside. E-may then be pulled tight
and seenred by tying one end into a knot, or otherwise making it thicker so as to
prevent it from slipping through the aperture in the rim, and (a)-securing the other
end by laying it against the rim and then cramping-it-down by pressing a small
plate against it, the plate, which may be grooved to fit against the band, cord or
wire, having a hole through which a screw, fixed to the rim, passes, and being held
down by means of a nut, (b) by forming the end into a loop and securing it to a
hook or pin-fixed on the rim, (c) by folding the end round two hooks or pins fixed
on the rim and tying if a flexible band or cord be used; or the two ends may be
both-secured by cramping as described with reference to one end, or by tying, or in
any other convenient way. One of the edges of B may be turned over or turned
over at intervals and fastened so as to form a loop-in-section by which means E-is
kept in position.
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
4. The method, as described, of hooking the rim to the tyre so that A and B
form together a kind of tube capable of resisting the internal pressure produced by
the air when D is inflated.
2. The method of holding down the edges of B-against the rim, as described, by
means of the band, wire or cord E, so that B is not easily removed from the rim
when the wheel is in use, even when the internal pressure is removed.
