PROVISIONAL SPECIFICATION.
Improvements in and relating to Pneumatic Tyres for Cycles and
other Vehicles.
I, JAMES SOUTTER MARTIN, of 40 Victoria Road, Dundee, in the County of
Forfar, Scotland, Cycle Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in pneumatic tyres for cycles and other
vehicles, the object being to provide means for obtaining access to the inner
inflatable air tube or to the inside of its cover.
In carrying out my invention according to one modification I employ two con-
tinuous bands or hoops-such bands or hoops consisting of either solid rings or of
bands coupled together to form rings these hoops lying loosely in the rim. The
tyre cover is provided at each edge with a series of hooks whose purpose is to
engage with the adjacent hoop. When the inner tube is inflated the cover, acting
on the bands by means of these hooks, in a radial direction, places them in tension.
Sometimes I may fix the hooks to the wires and cause them to engage with eye-
lets in the edges of the cover. In some cases I may only employ one band or hoop
and cause all the hooks in the edges to engage with it, or conversely. Again I
may have the band or bands and the edges of the covers provided with hooks and
cause these to engage with each other when fastening on the cover.
In other cases I may have eyelets in the cover and double hooks lying within
the rim or fixed to the band or I may have hooks in the cover instead of the
eyelets.
Instead of wires I may employ a canvas band provided with eyelets for the pur-
pose of allowing the hooks in the edges of the cover to engage with them, or
conversely. The hooks may be of any width and placed quite closely together.
It is obvious that bands and hooks may be so modified as to secure the cover
in its place in other ways than those I have indicated.

COMPLETE SPECIFICATION.
Improvements in and relating to Pneumatic Tyres for Cycles and
other Vehicles.
I, JAMES SOUTTER MARTIN, of 40 Victoria Road, Dundee, in the County of
Forfar, Scotland, Cycle Engineer, 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 relates to improvements in pneumatic tyres for cycles and other

page_text: vehicles, the object being to provide means for obtaining access to the inner
inflatable air tube or to the inside of the cover.
And in order that my said invention and the manner of perforniing or carrying
the same into effect or practice may be properly understood, I have hereunto
appended an explanatory sheet of drawings in which the same reference numerals
are used to indicate corresponding parts in all the figures where shown, that is to
say:
Figure 1 is a cross section of a tyre and rim showing how the cover is held in
position by means of hooks.
.
Figure 2 is a part side elevation of same. showing how the hooks may be
attached to the cover.
Figure 3 is a cross-section of a tyre and rim showing, another modification and
Figure 4 is its respective elevation.
Figures 5 to 10 show other modifications in the methods of attaching or
securing the covers.
In carrying out my invention according to one modification which is illustrated
by Figures 1 and 2 I employ two continuous bands or hoops 11-such bands or
hoops consisting of either solid rings or of bands coupled together to form rings
these hoops lying loosely in the rim. The tyre cover 12 is provided at each
edge with a series of hooks 13 whose purpose is to engage with the adjacent
hoop 11. When the inner tube 14 is inflated the cover 12, acting on the
bands 11, by means of these hooks, in a radial direction, places them in tension.
Sometimes as illustrated by Figures 3 and 4-I may fix the hooks 13. to the
wires 11 and cause them to engage with eyelets 15 in the edges of the cover 12.
In some cases I may only employ one band or hoop 16 and cause all the hooks
in the edges to engage with it or conversely. Again I may have the band or bands
and the edges of the covers provided with hooks and cause these to engage with
each other when fastening on the cover.
In other cases I may have eyelets in the cover and double hooks lying within
the rim or fixed to the band, or I may have hooks in the cover instead, of the
eyelets.
Instead of wires I may employ a canvas band provided with eyelets for the pur-
pose of allowing the hooks in the edges of the cover to engage with them, or
conversely. The hooks may be of any width and placed quite closely together.
These various modifications are illustrated by Figures 5 to 10 in which Figure 5
shows a series of double hooks 13 held in position by a single hoop 16, eyelets 15
in the cover engaging with such hooks.
Figure 6 shows a somewhat similar modification to that illustrated by Figure 5
except that the series of double eyelets 15 are attached to the rim by a hoop 16,
hooks 13 on the edges of the cover engaging with them.
Figure 7 illustrates an arrangement in which double hooks 17 engage with
hooks 13 on the edges of the cover.
Figure S shows how the hooks to which the cover is attached may be threaded
on to the hoop 16.
Figure 9 shows a canvas or other band 16 with the hooks 13 attached thereto,
eyelets in the cover 12 engaging with them.
Figure 10 shows a canvas or other band 16 provided with pockets at its edges
in which are wires or hoops 11. The hooks 13 on the cover 12 engage with these
wires, holes being made in the canvas to allow their points to pass through.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In pneumatic tyres, the mode of securing the cover to the bands within the
rim as described with reference to Figures 1 and 2 of the drawings.
2. In pneumatic tyres, the modification as herein before described with refer-
ence to Figures 3 and 4 of the drawings.

page_text: 3. In pneumatic tyres, the modification hereinbefore described with reference
to Figure 5 of the drawings.
4. In pneumatic tyres, the modification hereinbefore described with reference
to Figure 6 of the drawings.
5. In pneumatic tyres, the modification herein before described with reference
to Figure 7 of the drawings.
6. In pneumatic tyres, the modification herein before described with reference
to Figure 8 of the drawings.
7. In pneumatic tyres, the modification herein before described with reference
to Figure 9 of the drawings.
8. In pneumatic tyres, the modification herein before described with referenco
to Figure 10 of the drawings.
