PROVISIONAL SPECIFICATION.
Improvements in or relating to Pneumatic Tyres, and Valves for
Use therewith.
We ISAAC SHULMAN and LOUIS KRIEGER both of 35 Fournier Street,
Spitalfields, E. Boot Maker and Tailor respectively do hereby declare the nature
of this invention to be as follows:-
The object of this invention is to construct an inflated tyre having two or more
air spaces so that in the event of the cover of the outer space being punctured the.
inner or second air space will cause the division between the spaces to be held
against the inside of the punctured cover and also a valve so constructed that
either of the air spaces may be inflated independently of the other, the valve
being provided with two or more apertures as required, a rotating disc having an
aperture to which the nozzle of the pump is connected being employed, said
aperture being placed opposite the opening leading to the space to be inflated,
being secured in the desired position by means of a clamping screw or the like.
The outer cover or case of the tyre is secured to the rim at its edges by means of
a clamping ring or circular strip of suitable cross section which holds the wire
which runs round the edges of the cover, between the rim and said ring or circular
strip.
The division in the case of a two air space tyre is formed of a circular strip of
suitable material which is secured to the inside of the cover or case at or near its
edges so as to form an air tight joint by means of cement or the like. The
clamping ring or circular strip is secured in place by means of bolts passing
through apertures in the rim and which form airtight joints with said bolts, and
cam nuts or other convenient and well known means, said cam nuts being connected
together by means of chains or the like so that by operating one of the cam nuts
the others will also be operated and will actuate the ring or circular strip thus
releasing or securing the cover or case in position.

COMPLETE SPECIFICATION.
Improvements in or relating to Pneumatic Tyres, and Valves for
Use therewith.
We, ISAAC SHULMAN and LOUIS KRIEGER both of 35 Fournier Street,
Spitalfields E. Boot Maker and Tailor respectively, 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:—
The object of this invention is to construct an inflated tyre having two or more

page_text: air spaces so that in the event of the cover of the outer space being punctured the
inner or second air space will cause the division between the spaces to be held
against the inside of the punctured cover and also a valve so constructed that
either of the air spaces may be inflated independently of the other, the valve being
provided with two or more apertures as required a rotating disc having an aperture
to which the nozzle of the pump is connected, said aperture being placed opposite
the opening leading to the space to be inflated, being secured in the desired
position by means of a clamping screw or the like.
The outer cover or case of the tyre is secured to the rim at its edges by means
of a clamping ring or circular strip of suitable cross section which holds the wire
which runs round the edges of the cover between the rim and said ring or circular
strip. The division in the case of a two air space tyre is formed of a semicircular
strip of suitable material which is secured to the inside of the cover or case at or
near its edges so as to form an air tight joint by means of cement or the like. The
clamping ring or circular strip is secured in place by means of bolts passing
through apertures in the rim and which form air tight joints with said hofts, and
cam nuts or other convenient and well-known means, said cam nuts being connected
together by means of chains or the like so that by operating one of the cam nuts
the others will be operated and will actuate the ring or circular strip thus releasing
or securing the cover or case in position.
Referring to the annexed drawings
Figures 1, 2, 3, are cross sections of my tyre..
Figures 4, 5, 6, 7, 8, 9, 10 are cross sections of the rims and locking arrange-
ments for securing the tyre in position in the rim.

In Figure 1a is a piece of suitable material such as india rubber which is
secured to the outer cover or tube b at c and turns round the wire d which secures
the outer cover or tube bin the rim e. f is an elastic band which encircles the
piece a and prevents same from coming iuto contact with the outer cover or tube b
until required.
In Figure 2 the piece a is secured to the outer cover or tube at g, g.
In Figure 3 the piece a is employed as before but is encircled by a flat band fi
instead of a round one. In the event of the outer cover or tube being punctured
the piece a may be inflated by means of a valve to be described hereafter and
shewn in Fig. 12. The parts i are stamped or formed as shewn of various cross
sections & are pivotally secured upon the pin or stud ; which is in turn carried by
the rim e. The pieces i are of an oval or elliptical outline and may have ribbed
or corrugated parts at k (Fig. 5). The edges of the outer cover or tube are
secured between the rim & pieces i at or about the. position 1. The parts i are
connected together by means of chains or connecting bars so that by operating
one piece the others will also be operated. One or more of the pins or studs
may project through the rim being attached in that case to the piece so that the
same may be rotated from the outside of the rim by means of the pin or stud, the
junction of same with the ring being made air tight by any well-known or convenient
arrangement.
Referring to Fig. 11, the wire for securing the outer cover or casing to the tyre
is shaped as shewn, the ends being bent round as shewn after passing through the
edges of the outer cover or casing and thus being a continuous wire connection.
Referring to Fig. 12, the casing is secured in the rim e by means of the nuts m.
nare the valves which are controlled by the springs n. q is a rotating disc
carrying the tube p which is connected to the pump by rotating the disc q, the
tube p will communicate with either of the valves n, r being a setscrew for securing
or locking the disc g in the desired position. w is a tube which communicates
with the space between the outer cover b and piece a, v being the aperture
which communicates with the space upon the other side of the piece a. t is a cap
for covering the pivoted disc q, being secured by the chain n' to the valve body l

outlets, thus facilitating the passage of the air to the tyre. s is the pivot upon
which the disc q rotates.

4 are projections formed upon the ends of the tubes or apertures 2 and 3 and
which engage in corresponding indentations in the disc q so as to ensure a tight
joint. If desired washers may be employed to render the joint between the
disc q and ends of apertures 2 and 3 airtight.
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 combination a piece of material attached to the inside of the outer cover
or casing and forming a division in the air tube, being encircled by a flexible
band for preventing the said piece from coming into contact with the inner
surface of the air tube until required.
2. In combination; a rim in combination with stamped up plates having corru-
gated or ridged surfaces, said pieces being pivoted upon studs or pins carried in
the rim, said stamped up plates securing the outer cover or casing in the rim.
3. In valves for inflating tyres a valve having two channels in which valves
controlled by springs are carried; a rotating disc having an aperture which may
be brought opposite either channel as required, said rotating disc being secured
in the desired position by a set screw.
Substantially as described.
