THOMAS LIGHTBOURN, of 12, Union Street, Blackburn, Painter, THOMAS PREST,
of 389, Whalley New Road, Blackburn, Grocer's Assistant, and MARY PREST,

do hereby declare the nature of this invention to be as follows:-
The object of our invention is to do away with all puncturing in which we
employ cork made in one or more pieces to fit on rim with two loose ends so as
to do away with the inner tube. Then we employ single canvas with two loose
ends and solution down by each side about half an inch so that we can place
two full wires projecting out at each ends to put through a small hole in centre
of rim or we can fix four halfs to put through two holes one at the top and the
other at the bottom. After we fit on at a stretch an india rubber cover with two
or more holes and small pieces of canvas solutioned round each hole to let the
We
wire pass through the hole or holes in centre of rim at the top or bottom.
have also small nuts and bolts fitted through the rim near holes in which we
can fix on the wires to prevent the tyre coming off.
In performing our invention we employ cork made in one or more pieces with
two loose ends to fit on rim. Then we use a canvas cover with two loose ends
solutioned down by each side about half an inch to put one wire through each
side with projecting ends, or we put two half wires down each side of canvas to
fasten through two holes in rim one at the top and another at the bottom. After
we place an india rubber cover on at a stretch with either two holes in so as to
pass the four ends of the two full wires, or four holes with two at the top and
two at the bottom to pass the half wires through on the same principle we solu-
tion round small piece of canvas on every hole in rubber cover so as to prevent
it from tearing. The rim has either two holes at the top and bottom or at one
place only for the wires to pass through and small nuts and bolts fitted near each to
fasten wires.
How To FrT ON RIM.
In the first place we take the cork and then we put the canvas round which
can either be solutioned to the cork or not and pull at each wire until quite
tight. After we put on at a stretch the rubber cover and pass the wires through
the holes in rubber cover then we solution the rubber round the back side of
canvas, or we can stretch ruber round and solution each side together. We then
take hold of each loose ends of cork and canvas and pulling the rubber stretching
allows it to fit on rim. Then we pull the wires tightly and fasten to small nuts

the rim and fasten the wires after so preventing it from working loose.

Improvements in Elastic Tyres for the Wheels of Cycles and other
Vehicles.
We, JAMES PREST, of 389, Whalley New Road, Blackburn, Clerk, WILLIAM
THOMAS LIGHTBOURN, of 12, Union Street, Blackburn, Painter, THOMAS PREST,
of 389, Whalley New Road, Blackburn, Grocer's Assistant, and MARY PREST,
of 389, Whalley New Road, Blackburn, Spinster, all in the County of Lancaster,
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 improvements in elastic tyres for cycles and other
vehicles, the object being to obviate all liability of puncturing by employing
an inner tyre or core of cork instead of an inner tube filled with air as in the
pneumatic tyre. The invention consists in the method of and means employed for
fixing the elastic tyre and its covering in position on the rim of the wheel.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying draw-
ings, in which:
-
Fig. 1 is an elevation, partly in section, of one of the improved tyres.
Fig. 2 is a cross section of the elastic core and its covering.
Fig. 3 is a cross section of the improved tyre shewing the means of securing
the cover.
According to this invention we employ a core or inner tyre of cork 1 made in
one, two, or more pieces, segments, or lengths, placed on the rim 2 with their
ends abutting against one another (see Fig. 1). The cork core or tyre 1 is held
in position on the rim 2 by means of a covering of rubber 3 and canvas 4 about
semi-circular in cross section (see Figs. 2 and 3). To each edge of the outer
rubber covering 3 there is secured by the canvas 4 which is cemented to the
inner face of the rubber 3, a wire or wires 5 extending the length of the covering,
and the ends of these wires 5 are passed through holes 6 in the rim 2 and
tightened and then secured by means of nuts or solder so that the whole is
securely held in position. In order to get the rubber outer covering 3 into
position over the cork inner tyre 1 the former is slightly stretched and when
in position it contracts and is further tightened by the wires 5 of which two or
more may be employed.
The canvas 4 is cemented to the inner face of the rubber covering 3 and over
the whole of its surface but not in one continuous length or the rubber could
not be stretched so as to get it into position over the cork core 1, but one, two
or more strips of canvas 4 are employed so that the rubber covering 3 may be
stretched between the ends of each strip 4, and when stretched and contracted
into position the whole is secured by the wires 5.
One wire 5 may be used for each edge of the covering 3-4, or two or more
on each side (see Fig. 1).

page_text: If the ends of the wires 5 are bent over and along the rim 2 and soldered,
a neat and secure appearance and finish is given, but the tyre cannot so readily
be removed as when nuts are employed.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is:
-
(1) The improved elastic tyre as herein described and substantially as illus-
trated by the annexed drawings.
(2) The method of and means employed for securing the elastic inner tyre or
core to the rim of the wheel as herein described and substantially as illustrated
by the annexed drawings.
