PROVISIONAL SPECIFICATION..
An Instrument to Facilitate the Removal of the Covers of Inflated
Tyres.
We, WILLIAM BEARD LAKE, of New Street Works, Braintree, in the County
of Essex, Engineer, and JAMES BRADBURY, Junior, of Ashgrove House, Tudor
Road, Ashley Road, Bristol, in the County of Gloucester, Cycle Manufacturer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to an instrument to facilitate the removal of the covers of
inflated tyres.
Inflated tyres for velocipedes, and such, for example, as that class known as the
"Dunlop" are held in place in the rim or felloe of the wheel and protected by
means of a cover which constitutes a wearing or running surface and this cover is
removeably secured to the rim or felloe of the wheel by means of a wire ring at
each edge thereof.
In order to remove the cover when access is desired to the tyre or inflated tube,
it is necessary to lift the wire rings out of their seats and over the edge of the rim
or felloe, and this operation, in the absence of a special tool, is a difficult and
troublesome one.
Now the object of the present invention is to provide a simple and inexpensive
instrument, adapted to be carried in the pocket or satchel, by the aid of which the
wire rings may be quickly removed from the rim or felloe without difficulty or
injury.
For this purpose, a handle is formed by bending a suitably shaped strip of metal
into a flat loop, the strip of metal forming the scales or sides of the handle and
between the free or meeting ends of the loop or scales is pivotally mounted, at
about the centre of its length, a curved blade which is thus adapted to partially
fold within the handle when the instrument is out of use.
The curved blade is formed of a strip of metal shaped longitudinally to a suitable
radius so that its sides follow the required curve and one edge of this blade is
turned up at a right or other suitable angle and in a direction away from the axis
of the curve of the blade.
When it is desired to remove the cover of a tyre of the character hereinbefore
referred to, the contained air is allowed to escape from the tyre, one of the wire
rings of the cover is then brought at the desired part, as near the edge of the felloe
as possible and the blade of the instrument, which is turned upon its pivot at right
angles to the handle, is inserted between the said ring of the cover and the felloe,
the handle of the instrument is now pressed downward towards the centre of the
wheel and the wire ring forming the edge of the cover is readily levered over the
side of the felloe.

We, WILLIAM BEARD LAKE, of New Street Works, Braintree, in the County
of Essex, Engineer, and JAMES BRADBURY, Junior, of Ashgrove House, Tudor
Road, Ashley Road, Bristol, in the County of Gloucester, Cycle Manufacturer, 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 an instrument to facilitate the removal of the covers of
inflated tyres.
Inflated tyres for velocipedes and such for example as that class known as the
"Dunlop" are held in place in the rim or felloe of the wheel and protected by
means of a cover which constitutes a wearing or running surface and this cover is
removably secured to the rim or felloe of the wheel by means of a wire ring at each
edge thereof.
In order to remove the cover when access is desired to the tyre or inflated tube,
it is necessary to lift the wire rings out of their seats and over the edge of the rim
or felloe, and this operation, in the absence of a special tool, is a difficult and
troublesome one.
Now, the object of the present invention is to provide a simple and inexpensive
instrument, adapted to be carried in the pocket or satchel, by the aid of which the
wire rings may be quickly removed from the rim or felloe without difficulty or
injury.
And in order that our invention may be thoroughly understood, we now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a front elevation of the instrument.
Fig. 2, is a side view.
For this purpose, a handle is formed by bending a suitably shaped strip of metal
into a flat loop, the strip of metal forming the scales or sides of the handle a and
between the free or meeting ends of the loop or scales is pivotally mounted, at
about the centre of its length, a curved blade 6 which is thus adapted to partially
fold within the handle when the instrument is out of use.
The curved blade b is formed of a strip of metal shaped longitudinally to a
suitable radius so that its sides follow the required curve and one edge c of this
blade 6 is turned up at a right or other suitable angle and in a direction away from
the axis of the curve of the blade.
When it is desired to remove the cover of a tyre of the character hereinbefore
referred to, the contained air is allowed to escape from the tyre, one of the wire
rings of the cover is then brought, at the desired part, as near the edge of the
felloe as possible and the blade 6 of the instrument, which is turned upon its
pivot d at right angles to the handle, is inserted between the said ring of the cover
and the felloe.
The handle of the instrument is now pressed downward towards the centre of the
wheel and the wire ring forming the edge of the cover is readily levered over the
side of the felloe.
The handle may be made in the shape of a spanner or any other well known
tool.

page_text: 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. In an instrument to facilitate the removal of the covers of inflated tyres from
the rims of wheels, the combination of the handle a and curved blade 6 with the
curved edge c, and the pivot d to work or connect the handle to the curved blade,
substantially as herein described and according to the accompanying drawing.
2. An instrument for the removal of the covers of inflated tyres from the rims
of wheels, constructed as herein before described and for the purpose specified.
