Improvements in or relating to Pneumatic Tyres
Year: 1898

page_text: Improvements in or relating to Pneumatic Tyres,
JOHN HENRY PRICE, of 164, Corporation Street, Birmingham, Agent, do hereby
declare the nature of this invention to be as follows:-
My invention relates to certain improvements in constructing and attaching
a pneumatic tyre to the wheel rim.
One part of my invention refers to that form of pneumatic tyre in which the
cover is held on to the rim by the air within the tube pressing down upon and
contracting flat metal bands with overlapping ends which lie within or are attached
to the edges of the cover and are adapted to lay flat upon the bed of the rim.
My improvements consists in providing such metal bands with spring or elastic
connections in one or more places so that such bands may more easily be stretched
over the edges of the rim and also spring down to and grip the bed of the rim
by virtue of the said springs. The air pressure afterwards binding the whole
firmly to the rim.
Another part of my invention consists in forming a spring base for a tyre by
constructing either upon one or both edges of a cover, bands of wire or fabric or
springs and other suitable material which shall be elastic lengthwise but rigid
and non-compressible sideways, such bands forming the elastic base of the tyre
which springs on to and grips the rim and is afterwards acted upon by the air
pressure to securely lock the tyre upon the rim.
Such elastic bands may be placed within the base of a tubular tyre for the
purposes of attachment.

JOHN HENRY PRICE, 164, Corporation Street, Birmingham, Gentleman, 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 certain improvements in constructing & attaching a
pneumatic tyre to the wheel rim.
One part of my invention refers to that form of pneumatic tyre in which the
cover is held on to the rim by the air within the tube pressing down upon &
contracting flat metal bands with overlapping ends which lie within or are attached
to the edges of the cover & are adapted to lie flat upon the bed of the rim.

to the rim.
Another part of my invention consists in forming a spring base for a tyre by
constructing either upon one or both edges of a cover bands of wire and fabric
or springs & other suitable material which shall be elastic lengthwise but rigid &

springs on to & grips the rim & is afterwards acted upon by the air pressure to
securely lock the tyre upon the rim.
Such elastic bands may be placed within the base of a tubular tyre for the
purposes of attachment.
Fig. 1 shows one method of making a spring band for use as hereinbefore
described. The ends a & a¹ of the different segments of the band are turned
back & arranged between these ends is a flat wire spring, B, which resists the
drawing together of the ends & makes the band as a whole elastic.
Fig. 2, shows another modification in which an elastic loop or spring, B attached
at a al gives a similar elastic band.
Fig. 3, shows a modification in which the metal bands a¹, a² & a³ are in seg-
ments and around them I place an elastic cord or band which tends to contract
the metal segmental band.
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:
-
1. The formation of elastic metal bands as and for the purposes hereinbefore
described.
2. The improved method of attaching tyres to their rims by means of elastic
bands as hereinbefore described & illustrated with reference to Figs. 1, 2, & 3.
