PROVISIONAL SPECIFICATION.
Improvements in the Construction of Bicycle and other Pneumatic
Tyres for the Prevention of Puncturing of the Air Tubes.
ARTHUR CHARLES FAULKNER, of Velmead Cottage, Fleet, Hants, Assistant Overseer,
and ALFRED IVAR SMITH, of Broad St., Fleet, Hants, Assistant Overseer, do hereby
declare the nature of this invention to be as follows:-
We provide a shield in the form of a band of aluminium or other metal or other
suitable material of a flat or curved section and extending around the whole circum-
ference of the tyre. This band may be continuous or preferably may not be joined
and one end allowed to lap over the other so that the band may expand and increase
in diameter as the air tube is inflated.
The band may be placed between the outer casing and the airtube independently
or it may be incorporated with casing itself. In either case the interposition of the
band will have the effect of preventing the puncture of the air tube.
We provide at the point where one end of the band overlaps the other a suitable
means of preventing the air tube being cut or punctured by the end itself of the band,
and we also provide for a similar protection all around the edges of the band on each
side.
Dated this 21st day of July 1898.

Improvements in the Construction of Bicycle and other Pneumatic
Tyres for the Prevention of Puncturing of the Air Tubes.
ARTHUR CHARLES FAULKNER, Assistant Overseer, Velmead Cottage, Fleet, Hants,
and ALFRED IVAR SMITH, Assistant Overseer, of "Westacres," Fleet, Hants, late of
Broad Street, Fleet, Hants, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
We provide a shield in the form of a band of aluminium or other suitable material
or combination of materials of either a flat or curved section, preferably of a curved
section and extending completely around the circumference of the tyre between the
outer cover and the air-tube.
This band or shield may be continuous or not; that is, the ends may be joined so

page_text: as to form a complete hoop; or the ends may be left free, and in this case the one
end of the band or shield will overlap the other lengthwise. This band or shield may
be placed between the outer cover and the airtube independently of either, or it may
be affixed to the inside of the outer cover or to the outer circumference of the air tube
itself, so that the interposition of the band or shield will prevent the puncturing or
damage of the airtube. The band or shield may be constructed of rolled or other-
wise worked aluminium or other suitable metal; and in this case, where the band or
shield is continuous in the form of a hoop we provide a suitable means of protecting
the edges of the metal by canvas or other suitable material to prevent the edges
cutting or damaging the airtube when inflated; and in the case where the
band or shield is made with free and overlapping ends, we provide for the pro-
tection of the edges of the ends in a similar manner at the same time allowing for
the expansion of the band or shield in diameter, through the ends being free, as the
airtube is inflated or, we make the band or shield of some suitable pliable material
such as canvas; to which, around the whole of the circumference are affixed short
pieces of aluminium or other suitable metal or material of a flat or curved section,
preferably curved; each piece being fixed to the pliable material at or near one of its
ends; the other end being left free; or the pieces may be fixed at or near the middle,
both ends being left free; the length of each piece being such that it overlaps the
end of the next piece on the band and this succession of pieces being continued all
around the band of pliable material forms a continuous and flexible shield to protect
the airtube from injury; the airtube, when inflated, being protected from the metal
edges of the pieces by the pliable canvas or other material to which the pieces are
affixed.
This composite band or shield may be continuous, that is, with the ends joined ;
or the ends may be free. It will thus be seen that as the airtube expands through
inflation it will press the band or shield against the inside face of the outer cover,
and there will be a complete shield or band of protecting aluminium or other metal
or combination of metal and pliant material between the inside of the outer cover
and the airtube.
This composite band or shield may be placed between the airtube and the outer
cover independently or may be fixed to either the air tube or outer cover.
In the drawings Fig. 1 is a side and end view of the solid or continuous band.
Fig. 2 is the side and end view of the band non-continuous and with overlapping ends.
Fig. 3 is a section of the band and airtube and outer case, in which A is the outer
cover, B the metal band D D the strips of canvas or other protecting material for
protecting the edges. E E two of the rivets fastening this material to the band
and C is the airtube. Fig. 4 shows the method of protecting the overlapping ends of
the band and here A is the outer cover, B the band and D¹ a piece of canvas or other
material rivetted or fastened to the end of the band B in a similar manner to that
shown on Fig. 3 with which it is combined. Figs. 5 & 6 are longitudinal and cross
sections of the composite band or shield in which A is the outer cover B B the metal
portions of band in short overlapping lengths, C the airtube, F the pliable material,
E the rivets for fastening the metal to the pliable material.
Fig. 7 shows a different method of overlapping the short metal pieces. The same
letters of reference apply to Figs. 5, 6, & 7. It must be understood that the
dimensions of the various parts as shown in the drawings may be varied or altered as
may be convenient, as well as the particular details of fastenings, or overlapping of
the metal sections.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
In pneumatic tyres
1. The interposition of a band or shield of protective material between the airtube

page_text: 2. The construction of the band or shield of solid rolled or worked aluminium or
other suitable metal with protected edges and ends as hereinbefore described.
3. The construction of the composite band or shield of pieces of aluminium or other
metal in combination with the pliable material as hereinbefore described.
