PROVISIONAL SPECIFICATION.
Improved Method of Fixing Pneumatic Tyres to Wheels.
CHARLES JAMES PARRY, 186, Warner Road, Walthamstow, Essex, Artist, do
hereby declare the nature of this invention to be as follows:-
My invention relates to an improved method of attaching and detaching the covers
of pneumatic tyres to & from the wheels of cycles & other vehicles. An inner
tube which contains the air, pumped into same by means of a valve in the usual way,
lies round the rim of the wheel, & is held in position by means of a cover composed
of canvas or other suitable material, called a "jacket," the outer side of which is
covered with rubber in the ordinary way attached to samo by solution or vulcanising
& the like. In both sides of the "jacket" are inserted wires, the wire on either
side being fitted by passing it once or oftener round the inside of the edge of the
"jacket," called the "pocket" & either hooking one end through the canvas or
other material which can be strengthened where pierced by button holing, eyelets,
or any suitable method, or by forming the end or other parts of the wire into loops
which can be rivetted or stitched to the cauvas or other material, or by attaching
hooks or plates to the wire, either at the end or elsewhere, the same being hooked
or rivetted to the canvas, or by means of tape or any suitable method.
The other end of the wire is made to emerge from the pocket & to extend for
some distance on the outside of the "jacket." On or near this end of the wire is
fixed a kind of shovel or metal plate, which is shaped to fit into the groove in the
inside of the edge of the rim, & is placed between the edge of the "jacket" &
the rim, after having been pulled tight, being held in position by the wire enclosed
in the "pocket" pressing thereon when the tyre is inflated.
To detach or open this cover the tyre is pressed back over either of the shovels
which is thus released & the portion of wire which is outside being pushed into the
pocket," the edge of the "jacket" on that side becomes enlarged & is readily
lifted over the edge of the rim.

of Essex, Artist, do hereby declare the nature of this invention and in what manner

page_text: the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
-
My invention relates to an improved method of attaching & detaching the covers
of pneumatic tyres to & from the wheels of cycles & other vehicles.
An inner tube which contains the air pumped into same by means of a valve
in the usual way, lies round the rim of the wheel & is held in position by means of
a cover composed of canvas or other suitable material, called a "jacket," the outer
side of which is covered with rubber in the ordinary way, attached to same by
solution or vulcanising & the like.
In both sides of the "jacket" are inserted wires, the wire on either side being
fitted by passing it once or oftener round the inside of the edge of the "jacket
called the pocket," & either hooking one end through the canvas or other material
which can be strengthened where pierced by buttonholing, eyelets, or any suitable
method, or by forming the end or other parts of the wire into loops which can be
rivetted or stitched to the canvas or other material, or by attaching hooks or plates
to the wire either at the end or elsewhere, the same being hooked or rivetted to the
canvas, or by means of tape or any suitable method of attachment.
The other end of the wire is made to emerge from the "pocket" & to extend
for some distance on the outside of the "jacket" A Figs. 2 & 3.
On or near this end of the wire is fixed a kind of shovel or metal plate B
Figs. 1, 2, 3, which is shaped to fit into the groove in the inside of the edge of the
rim, & is placed between the edge of the "jacket" or cover & the rim, after having
been pulled tight, being held in position by the wire (enclosed in the "pocket")
pressing thereon when the tyre is inflated Fig. 1.
The shape of the plate or shovel can be varied to fit any kind of rim required or
the wire itself may be bent into the required form for the same purpose.
"
To detach or open this cover the tyre is pressed back over either of the "shovels
which is thus released & the outside end or portion of the wire carrying the "shovel,”
springs up A Fig. 2, & the same being pushed into the "pocket," the edge of the
cover becomes enlarged & rises above the rim, when it can be readily lifted off,
Fig. 3.
"
It is obvious that I may vary the arrangement of my wires, for instance I may
cause both ends of the wire to emerge from the " pocket & proceed along the
outside of same for some distance in opposite directions, each portion carrying a
shovel," or being bent into the necessary shape, so that it can be placed between
the edge of the cover & the rim, & thus held firmly in position when the tyre is
inflated.

Having now particularly described & ascertained the nature of my said
invention, & in what manner the same is to be performed, 1 declare that what I
claim is:-
1st. In pneumatic tyres made substantially as hereinbefore described.
2nd. In pneumatic tyres wires which are attached at one end or other part to the
cover itself, substantially as herein before described.
3rd. In pneumatic tyres wires one or both ends or other parts of which (carrying
plates or being themselves bent into the desired shape) are placed between the edge
of the cover & the rim, thus becoming immoveable when the tyre is inflated, sub-
stantially as herein before described.
