PROVISIONAL SPECIFICATION.
Improvements in and relating to Detachable Pneumatie Tyres for
Cycles, Motor Cars, and other Road Vehicles.
I, SUSANNAH RUTH STONE, 16, Bath Row, Birmingham, in the County of
Warwick, do hereby declare the nature of this invention, to be as follows:-
This invention consists firstly in employing two detachable concavo-convex
shaped bands of metal having a groove formed on their outer edges, the afore-
said bands being made with unjoined ends forming a broken circle, on the ends
of which are sliding flanges fitting into each other so that the bands can be
reduced in their circumference to fit any size of wheel.
These bands are placed and lie in the circumferential recessed bed of the rim
or felloe of the wheel or as a substitute I may use a rim with grooves formed
on its outer edges. Upon or near to the edges of the outer tyre cover suitable
button shaped metallic connections or their equivalents are fixed at given dis-
tances apart to engage with the aforesaid metallic bands.
When the button shaped metallic attachments are connected to the metal
bands and the tyre inflated a practically complete tube is provided.
By these improved arrangements the tyres can be fitted to any configuration
of rim and are securely attached thereto, at the same time can be readily detached
when deflated.

improvements in and relating to Detachable Pneumatic Tyres for
Cycles, Motor Cars, and other Road Vehicles.
I, SUSANNAH RUTH STONE, of No. 16, Bath Row, Birmingham, in the County
of Warwick, 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 consists firstly in employing two detachable concavo-convex
shaped bands of metal having a groove formed on their outer edges the afore-
said bands being made with unjoined ends forming a broken circle, on the ends
of which are sliding flanges fitting into each other so that the aforesaid bands can
be reduced in circumference to fit any size of wheel.

page_text: These bands are placed and lie in the circumfrential recessed bed of the rim
or felloe of the wheel or as a substitute I may use a rim with grooves formed
on its outer edges.
Upon or near to the edges of the outer tyre cover suitable button shaped
metallic connections or their equivalents are fixed at given distances apart to
engage with the aforesaid metallic bands.
When the button shaped metallic attachments are connected to the metal
bands and the tyre inflated a practically complete tube is provided.
By these improved arrangements the tyres can be fitted to any configuration
of rim and are securely attached thereto, at the same time can be readily detached
when deflated.
I may preferably use button shaped metallic connections having cylindrical
trumpet shaped hollow stems or shanks which pass completely through the
rubber and canvas of the outer tyre the cylindrical trumpet shaped ends of the
metallic connections coming next to the inner tube or air chamber, in such case
I find upon inflating the inner tube it is driven into the cylindrical trumpet
shaped ends of the metallic connections in such a manner as to hold the tyre
more firmly on the rim also the inflated tube is kept more steady within the
outer cover, by these means the friction on the inflated tube is much reduced.
Referring to the accompanying drawings Figure 1 represents a detachable
cancavo-convex metallic grooved band with sliding flanges.
Figure 2 represents a section and elevation of a portion of a tyre cover shewing
the position of button shaped attachments.
Figure 3 represents a button shaped metallic connection with cylindrical
shank.
Figure 4 represents a transverse section of a tyre and rim made according to my
invention a a the concavo-convex metallic bands-fixed in position in the rim
B B button shaped metallic connections C rim D inner tube E outer tubular
tyre cover.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:
.
The combination of a grooved rim or felloe of wheel fitted with two concavo-
convex bands of metal with grooved edges and sliding ends and a tubular tyre
cover of canvas and india rubber the edges of which are unthickened and are
extensible and fitted, with button shaped metallic attachments with cylindrical
trumpet shaped hollow shanks and an internal inflatable tube as arranged and
substantially described and shewn in drawings.
Dated this 23rd day of January 1899.
