Improvements in connexion with Pneumatic Tyres.
WILLIAM LIGGINS and PERCY WILLIAM LIGGINS Manufacturers 12 & 13:
White Friar's Lane Coventry, in the County of Warwick. We do hereby declare"
the nature of this invention to be as follows:-
The object of this invention is to make a detachable band for the inside of the
rim of the wheel or felloe 'to protect the air tube from the heads of the spokes in
the wheel, we make the band of a woven tubular fabric in cotton. or other material,
and we use part elastic attached to the tubular web fabric, and we attach this to ai
small metal part with a hole in the centre for the valve to go through, for the
purpose of inflating the air tube, by this means the band can be put on without any
trouble as the elastic will expand, and make it adjustable, it therefore saves very
much time and the web fabric being tubular makes it extra thick and makes a
good protection to the air tube from friction on the heads of the spokes in the
wheel.

Improvements in connexion with Pneumatic Tyres.
We, WILLIAM LIGGINS, and PERCY WILLIAM LIGGINS, of 12 White Friar's
Lane, Coventry, Manufacturers, 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 bands adapted to be placed in the inside or bed of the.
rims of wheels fitted with pneumatic tyres. Such bands are employed to protect.
the air-tubes of pneumatic tyres from injurious contact with the spoke heads or
nipples which project above the bed or inside surface of the rim. The object of
our invention is to facilitate the attachment and detachment of such bands and in
some cases to increase the protective powers of such bands, as compared with other
bands at present in general use.
Our invention consists essentially in introducing an elastic portion into the band,
so that it may be readily sprung onto or off from the rim, and in forming in the
elastic portion of the band an aperture for the stem of the valve or duct, to pass
through.
And in order that our invention may be properly understood and readily carried
into effect we will describe the same with reference to the accompanying sheet of
illustrative drawings but we do not confine ourselves to the precise details
shown therein as these may be modified without exceeding the scope of our
invention.
Figure is a plan view showing part of a band constructed according to our
invention.

page_text: Figure II is a similar view showing a modification.
Like numerals refer to like parts in both figures.
According to one method (Figure 1) of carrying out our invention we make the
band 2 preferably of a woven tubular fabric of cotton or other suitable material
and say three or four inches shorter than the circumference of the bed of the rim.
We press or otherwise make a small plate 3 with a central hole 4 and two
transverse slots 5, 5 one at each end. The hole 4 is adapted to receive the stem of
the valve or duct and the slots 5, 5 are adapted to receive loops 6, 6 of elastic
material. The plate 3 may be of brass or other suitable metal or material and it
may be "set" transversely to correspond to the formation of the rim. The ends of
the loops 6, 6 are stitched or otherwise suitably secured to the ends of the band 2
and are of such a length that when the band is slipped on to the rim it will be so
stretched as to maintain its position over the spoke heads under all ordinary
circumstances. The width of the band when in position may be about ", as
usual.
According to the modification shown in Figure II, we form the aperture 4 in the
elastic material itself by using narrow strips 6, 6 which are adapted to lie side by
side except in so far as they may be separated by the stem of the valve or duct 7.
The two strips 6, 6, may be formed of one piece looped at one end but so beld by
the stitching which unites the elastic to the band that they, the said strips, assume
their proper relative positions.
It will be obvious that the elastic strips 6, 6 whether employed with or without
the plate 3, may be similarly applied to the ordinary single or solid bands in general
use, though their protective powers are less in proportion to their comparative
thinness.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is,―
1. Constructing a band of the kind herein referred to with an elastic portion, so
that it may be readily sprung onto or off from the rim, such elastic portion being
also formed with an aperture for the stem of the valve or duct to pass through,
substantially as herein set forth.
2. The improved band for protecting the air-tubes of pneumatic tyres provided
with an elastic portion such as 6, 6 and an aperture in such elastic portion
such as 4, substantially as herein described and illustrated by Figure 1 of the
accompanying drawings.
3. The improved band for protecting the air-tubes of pneumatic tyres provided
with an elastic portion such as 6, 6, and an aperture in such elastic portion
such as 4, substantially as herein described and illustrated by Figure II of the
accompanying drawings.
