PROVISIONAL SPECIFICATION.
Improvements in Instruments for Removing the Covers of
Pneumatic Tyres.
We, ALFRED BLACKWELL, of Icknield Street, in the City of Birmingham,
Cycle Manufacturer, and GEORGE EMBREY BAILEY of 161 Devonshire Street,
Birmingham aforesaid, Press-tool Maker, do hereby declare the nature of this
invention to be as follows
1
This invention has relation to pneumatic tyre strippers, and has for its object, a
blunt instrument, incapable of injuring the air tube or sack on the stripping or
removal of the cover from the rim.
Now ordinary tyre strippers are apt to injure the inner tube should they come in.
contact with it.
According to our invention, the instrument consists of a stem or handle part,
terminated at the fore part by a spherical or bulbous end, that is to say, the end
fore part is made spherical or bulbous ended, with a shoulder, neck or contraction
under the head.
In using the instrument, pass the bulbous end under an edge of the cover, then
run the neck along the flange of the rim with the head as a guide, when the cover
edge will be rolled from off the rim, by the progressive motion and pressure of the
head against the edge of the cover.
The head if necessary may be made to rotate or swivel, that is, the fore part of
the instrument is made into a pivot, and upon it the spherical head turns.
The other end of the instrument may be made into the form of a screw-driver
or any other useful tool as may be required.

Improvements in Instruments for Removing the Covers of
Pneumatic Tyres.
We, ALFRED BLACKWELL, of Icknield Street, in the City of Birmingham,.
Cycle Manufacturer, and GEORGE EMBREY BAILEY of 161 Devonshire Street,
Birmingham aforesaid, Press-tool Maker, 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 has relation to pneumatic tyre strippers, and has for its object a
blunt instrument, incapable of injuring the air tube or sack on the stripping or
removal of the cover from the rim.
Now ordinary tyre strippers are apt to injure the inuer tube should they come
in contact with it.

fore part is made spherical or bulbous with a shoulder, neck or contraction under
the head.
In using the instrument, pass the bulbous end under an edge of the cover, then
run the neck along the flange of the rim with the head as a guide, when the cover
edge will be rolled from off the rim, by the progressive motion and pressure of the
head against the edge of the cover.
The head if necessary may be made to rotate or swivel, that is, the fore part of
the instrument is made into a pivot, and upon it the spherical head turns.
The other end of the instrument may be made into the form of a screw-driver or
any other useful tool as may be required.
Figure 1 of the accompanying drawings represents our new or improved
instrument in use.
Figure 2 is a front elevation of the said stripper and Figure 3 is an edge view
of it.
Figure 4 is a topside plan of the said stripper.
Figure 5 represents front and side elevations of a stripper with the stem end
formed into a screw-driver.
In Figures 1 to 4, a is the spherical or bulbous end of the instrument which has
a neck a¹ and a stem or handle part a².
In Figure 5, a is the bulbous head or spherical end, a' the neck, and a³ the body
or handle, which is formed into a screw driver end at a³.
Figure 6 represents the stripper instrument fitted with a swivelling or rotatory.
bulbous head.
Figure 7 is an elevation of the same whilst Figure 8 is a topside plan thereof
and Figure 9 shows the part separately.
In Figures 6 to 9, a is a rotatory bulbous head, swivelling upon a pivot end at,
and against the shoulder a³, of the fore end of the stem or handle a'. When this
form of stripper is in use, the head is run under the selvage edge of the cover
which is removed with considerably less friction than when a solid head is
employed.
As a modification, the instrument may have a bulbous head at each end, either
of the same or of dissimilar sizes.
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 :-
First. A tyre stripper or instrument for removing the covers of pneumatic tyres,
consisting of a handle part with a bulbous end or a head end, substantially as
described and set forth.
Secondly. A tyre stripper or instrument for removing the covers of pneumatic
tyres, consisting of a handle part with a rotatory or swivelling bulbous or head
end, substantially as described and set forth.
