1 ERNEST WILLIAM BEECH of 11 The Pavement, Wanstead, Essex, Builder
do hereby declare the nature of this invention to be as follows:-
This invention has for object certain improvements connected with cycle and
like tyres.
For the purpose of my said invention I employ a combination of pneumatic
tubes, spheres or their equivalents and a cover in which inner wings form a partition
to separate the tube and the spheres in different chambers or compartments. The
cover can be secured by inflating it into contact with the rim which may be lipped
or otherwise prepared for the lodgment of the inflated edges or spring steel rings
can be employed for gripping the edges of the cover the actual fixture being
effected by the inflation if so desired.
I purpose fitting the spheres (hollow or solid) in the chamber or chambers next
the tread of the cover and the tube between the partition wings and the rim.

I, ERNEST WILLIAM BEECH, of 11 The Pavement, Wanstead, Essex, Builder,
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 for object, certain improvements connected with cycle and
like tyres.
For the purpose of my invention and as represented in the annexed drawings,
1 employ a combination of pneumatic tube A spheres B, or their equivalents
within a cover C in which inner wings or flaps D, D, form a circumferential
partition to separate the tube A and the spheres B in different chambers or
compartments.
The cover C can be secured by inflating it into contact with the rim E which
may be lipped or otherwise prepared for the ledgment of the inflated edges F, or
spring steel rings G can be employed for gripping the edges of the cover C, the
actual fixture being effected by the inflation, if so desired.
I purpose fitting the spheres (hollow or solid) in the chamber or chambers next
the tread H of the cover and the tube A between the partition wings D, D, and
the rim E.
Figure 1 represents a section of my cover C with the flaps D, D, Figures 2, 3

page_text: and 4 hollow and solid spheres to fit within the tread portion, as at Figure 5, where
the flaps D, D, are shown as overlaps and against which when the tube A is
inflated a pressure is exerted on the flaps to fix them in their respective places, the
edges C, C, of the cover being forced into contact with the rim E, or if the tyre
be as shown at Figure 5, the edges C', C', of the cover C can be laced for insertion
into a rim and an independent ordinary cover be placed over C and the fixture
be by the inflation of .A as with an ordinary pneumatic tyre.
Figure 6 represents a method by which the inflation of the tube A can drive the
plain edges C of the cover C into a recess or channel F of the rim E, no other
fastening being necessary.
Figure 7 is a part longitudinal section of the tyre shown at Figure 5 with the
spheres B but these appliances may be of other shape such as I show at
Figure 8.
Figure 9 shows sufficient of a tyre in which the coiled or other spring wire G
can bear upon the edges C', C', of the cover in hollows or channels of the rim E,
the bite being as in the former case due to the inflation of the tube A..
This spring may be of band shape, as at Figure 10, which also shows the flaps
in partition form as part of the cover, said partition having a slit through which
the spheres can be passed and then be pushed round to fill the chamber.
Figures 11 and 12 show other forms of independent tyres to that shown or
suggested as a separate tyre at Figure 5.
At Figure 11, the outer shell I is of wire gauze or the like as a protection
from punctures, this can be placed in a rim and be covered by an ordinary cover,
the inflation of the tube A being sufficient to fix and retain the tyre in place.
Figure 12 shows a cover laced on the spheres instead of on the inflatable tube,
as at Figure 5. In this case, the spheres can be inserted or removed by unlacing
the cover C at any part but by the plan shown at Figure 5 the tube A can be
removed before the spheres.
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 :-
As a pneumatic tyre, the combination of spheres, or their equivalent, and
inflatable tube in a cover having flaps or a partition, as and in the manner shown
on the annexed drawings for the purpose described.
