Improved Protective Cover for Pneumatic Wheel Tyres.
I, CHARLES DENTON ABEL of No. 28 Southampton Buildings, in the County
of London, Consulting Engineer and Chartered Patent Agent, do hereby declare
the nature of this invention to be as follows:-
In the Specification to the application for a Patent dated 26th April 1895
No. 8316, was described a construction of protective cover for pneumatic_wheel
tyres, in which such cover was secured round the tyre by forming the one edge of
the cover with a single or double hook while the other edge was made with two
lappets that received the book or hooks of the other edge between them and; in
engaging therewith, held the cover securely when the tyre was inflated.
The present invention relates to an improved construction of such hooked
connection, which is applicable for pneumatic tyres of all kinds, whether for
velocipede wheels or wheels of other vehicles.
According to this improvement both edges of the covering are made double, or
with two lappets of different lengths; each such lappet being formed with a hook
that hooks into a hook on one of the lappets on the opposite side, thus affording a
double fastening, the several hooks being so arranged that, when hooked together,
the pairs lie more or less side by side, and thus do not increase the thickness of the
joint beyond that due to one of the hooks.
The fastening is shown on the accompanying drawing.
Fig. 1 shews a cross, section of the finished pneumatic tyre a with the rim 6 of
a wheel;
Fig. 2 a part plan of the covering c opened out;
Fig. 3 shews the edge view of the covering.
Each side of the covering is formed with two lappots.cc of unequal length,
cach of which is provided with a hook shaped fillet c c. The hooks of the
long lappets.c engage, when laid round the tyre, with the 'hooks o' of the shorter
Jappets c², as shown at Fig. 1. The middle hooks can overlap each other
slightly with their pointed' ende. The thickness of the fastening will then be about
equal to the thickness of the books at their thickest parts, and thus a tolerably
uniform bearing surface is formed on the enclosing caoutchouc ring d.
The one pair of hooks, in particular the longer part thereof, covers over the
other pair of hooks completely, and serves for securing the same in the closed
position. Any separation of this hooked fastening, when in use, is thus entirely
prevented. The other outside pair of books is held together by the caoutchouc
covering and the rim of the wheel.
The hooks are formed of a triangular stripe of caoutchouc or other suitable
material which is enclosed on all sides by the material of the cover. The
lappets o¹ c² may either be formed in one piece with the cover, or one or both of
each pair may be made separate and secured to the cover.
The attachment of the cover to the pneumatic tyre is effected in the known
manner, the latter being first only moderately inflated, after which the tyre is

page_text: fitted round it and the hooked lappets are hooked together. The caoutchouc
ring d is then applied, and the complete tyre thus formed is then fitted on the rim
of the wheel, and the pneumatic tyre is completely inflated.
Protective covers of the above described construction can be applied to wheels
of all descriptions having pneumatic tyres, such as velocipede, carriage, cab,
omnibus wheels &c.

COMPLETE SPECIFICATION.
Improved Protective Cover for Pneumatic Wheel Tyres.
1, CHARLES DENTON ABEL, of No. 28 Southampton Buildings, in the County
of London, Consulting Engineer and Chartered Patent Agent, 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 :-
In the Specification to the application for a Patent dated 26th April 1895
No. 8316, was described a construction of protective cover for pneumatic wheel
tyres, in which such cover was secured round the tyre by forming the one edge of
the cover with a single or double hook while the other edge was made with two
lappels that received the hook or hooks of the other edge between them and, in
engaging therewith, held the cover securely when the tyre was inflated.
The present invention relates to an improved construction of such hooked
connection, which is applicable for pneumatic tyres of all kinds, whether for
velocipede wheels or wheels of other vehicles.
According to this improvement both edges of the covering are made double, or
with two lappels of different lengths, each such lappel being formed with a hook
that hooks into a book on one of the lappels on the opposite side, thus affording
a double fastening, the several hooks being so arranged that, when hooked together,
the pairs lie more or less side by side, and thus do not increase the thickness of the
joint beyond that due to one of tho hooks.
On the drawing accompanying my Provisional Specification
Fig. 1 shews a cross section of the finished pneumatic tyre a with the rim 6 of a
wheel;
Fig. 2 a part plan of the covoring c opened out;
Fig. 3 shews the edge view of the covering.
Each side of the covering is formed with two lappels c¹³ of unequal length,
each of which is provided with a hook-shaped fillet c. The hooks c³ of the
long lappels engage, when laid round the tyre, with the hooks c of the shorter
lappels, as shewn at Fig. 1. The middle books ce can overlap each other
slightly with their pointed ends. The thickness of the fastening will then be
about equal to the thickness of the hooks at their thickest parts and thus a
tolerably uniform bearing surface is formed on the enclosing caoutchouc ring d.
The one pair of hooks, in particular the longer part thereof, covers over the
other pair of hooks completely, and serves for securing the same in the closed
position. Any separation of this hooked fastening when in use, is thus entirely
prevented. The other outside pair of hooks is held together by the caoutchouc
covering and the rim of the wheel.
The books are formed of a triangular stripe of caoutchouc or other suitable
material which is enclosed on all sides by the material of the cover. The
lappels.cc may either be formed in one piece with the cover, or one or both of
.each pair may be made separate and secured to the cover.
The attachment of the cover to the pneumatic tyre is effected in the known

page_text: manner, the latter being first only moderately inflated, after which the tyre is
fitted round it and the hooked lappels are hooked together. The caoutchouc
ring d is then applied, and the complete tyre thus formed is then fitted on the rim
of the wheel, and the pneumatic tyre is completely inflated.
Protective covers of the above described construction can be applied to wheels
of all descriptions having pneumatic tyres, such as velocipede, carriage, cab,
omnibus wheels &c.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A protective cover for pneumatic wheel tyres provided with two pairs of lappels.
of unequal length, such lappels being provided with hooks, and so arranged that
for securing the cover round the pneumatic tyre, the hook of a long lappel is made
to engage with the hook of a short lappel, substantially as described.
