Date of Application, 12th Dec., 1896
I, JOHN CLOUGH, of 4, Rose Bank, Manningham, in the County of York,
Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in pneumatic tires for cycles and other
light road vehicles.
For this purpose I make the edges of the tire or outer cover to overlap each
other against the rim or felloe of the wheel. Around the inner face of the edge
of the tire next to the rim I form a ridge or bead and I form a similar ridge or
bead around the other edge of the tire on the face next to the other ridge or
bead. These ridges or beads are preferably a suitable distance from the edges
of the tire and when the tire is in use they are placed one over the other and their
meeting faces are of such a form that when the tire is inflated the two ridges or
beads engage each other and hold the over lapping edges together.
Instead of continuous ridges or beads any suitable form of inter-locking
projections may be formed around the two edges of the tire.
The rim or felloe may be flat across or be crescent shaped, or of other curved cross
section. And the edge of the tire next to the rim may be secured to it in any
convenient manner.
The tire may be used either with or without an inner tube. In the latter case the
over-lapping edges and engaging ridges or their equivalent are faced with or
formed of a suitable substance for forming an air tight joint.

I, JOHN CLOUGH, of 4, Rose Bank, Manningham, in the County of York,
Manager, 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 pneumatic tyres for cycles and other
light road vehicles, and its object is to provide a tire which may be readily opened
to give access to the interior and which is held closed quite independent of the
rim or felloe.
For this purpose I make the edges of the tire or outer cover to overlap each other

page_text: against the rim or felloe of the wheel. Around the inner face of the edge of the
tire next to the rim I form a ridge or bead and I form a similar
ridge or bead around the other edge of the tire on the face next to the
outer ridge, or bead. These ridges or beads are preferably a suitable, distance
from the edges of the tire and when the tire is, in use they are placed one over
the other and their meeting faces are of such a form that when the tire is inflated
the two ridges or beads engage each other and holl the overlapping edges together.
Instead of continuous ridges or beads any suitable form of inter-locking
projections may be formed around the two edges of the tire.
The tire may be used either with or without an inner tube. In the latter case
the over-lapping edges and engaging ridges or their equivalent are faced with
or formed of a suitable substance for forming an air tight joint.
To more fully describe my. invention reference is made to the accompanying
sheet of drawings forming a part of this specification, in which similar letters of
reference indicate corresponding parts in each of the figures.
Figure 1, represents a cross section of a tire and rim made in accordance with
my improvements and provided with an inner air tube.
Figure 2, is a similar view with the outer cover open and the inner tube removed.
Figure 3, is a similar view to Figure 1 showing a tire that can be used without
an inner tube.
The outer cover A is cemented or secured to the rim B in any suitable way and
an overhanging bead C is formed round the edge of the part secured to the rim.
A similar overhanging bead D is secured round the other or loose edge of the
cover and this edge is sufficiently large in diameter that it can be passed over
the bead C when the tire is deflated but assumes the position shown with the over-
hanging faces of the beads hooked within or interlocked with each other when
the inner tube E is inflated. The beads C and D are vulcanized or hardened
sufficiently to retain their relative position when closed quite independent of any
support afforded by the rim.
When an inner tube E is not used a circumferential flap F of soft or pliable
rubber is formed round the loose edge of the tire and the inside face H of the tire
is made smooth and soft so as to adapt it to make an air-tight joint with the face
of the flap next to it.
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 means herein shown for connecting the opening edges of pneumatic tires
independent of the rim or felloe."
2. The improvements in pneumatic tires herein shown and described and
illustrated in the accompanying drawings.
