PROVISIONAL SPECIFICATION
Improvements in Means for Attaching Pneumatic Tyres or Cases
therefor to the Rims of Wheels.
We, TномAS WILLIAM TUPPER, of 116 Falcon Road, Clapham Junction,
in the County of London, Engineer, and THE ENGLISH CYCLE AND TYRE COMPANY
LIMITED of South Street Wandsworth London Manufacturers do hereby declare
the nature of this invention to be as follows:
This invention relates to improvements in means for attaching pneumatic tyres
or cases therefor to the rims of wheels, and especial objects of my invention
are (1) to obviate the necessity of making the edges of the cases unstretchable
by means of wires or equivalent means and (2) to fix the edges of said cases in the
manner substantially as hereinafter described whereby said edges will be gripped
even when the tyre is deflated.
In carrying out our invention and describing my invention with reference to
a case for a tyre, we make or form the edges of said case with a beading or en-
largement, and I provide a band-say of metal-within the groove of the ordinary
rim the said band being capable of being tightened up against the rim by means
of, say, right and left hand screws which connect the ends of said band, the
arrangement being such that if the enlarged or beaded edges of the case be
slipped or inserted between the rim and the band referred to and said band be
tightened up, the edges of the case will be firmly gripped.
For the purpose of enabling the right and left hand screw to be turned when the
edges of the case have been placed in position, we prefer to form said screw with
an enlargement which may be readily turned through an aperture in the rim of
the wheel, which aperture may be closed up when the case or tyre has been fixed.
We do not confine ourselves to any particular material of which the band may
be made and we prefer that the edges of the case be made of material sufficiently
elastic to enable said edges to be stretched over the edges of the rim.

Improvements in Means for Attaching Pneumatic Tyres or Cases
therefor to the Rims of Wheels.
We THOMAS WILLIAM TUPPER of 116 Falcon Road Clapham Junction
London, Engineer, and TIE ENGLISHI CYCLE AND TYRE COMPANY LIMITED of
South Street Wandsworth London, Manufacturers, 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 means for attaching pneumatic tyres
or cases therefor to the rims of wheels, and especial objects of this invention
are (1) to obviate the necessity of making the edges of the cases unstretchable
by means of wires or equivalent means and (2) to fix the edges of said cases in the
manner substantially as hereinafter described whereby said edges will be gripped
even when the tyre is deflated.
In order that this invention may be readily understood reference is made to
the accompanying drawing wherein like letters of reference indicate corresponding
parts throughout the several figures and in which
Fig. 1. shows our invention in sectional view as applied in attaching a tyre
case.
Fig. 2. shows our invention in side elevation, and
Fig. 3. is a perspective underside view thereof.
In carrying this invention into practice and describing said invention with
reference to a tyre case we make or form said case A at its edges with a beading
or enlargement a and we provide a band B say of metal within the groove of an
ordinary rim C the said band B being capable of being tightened up by means of,
say, right and left hand screws D which screw into lugs d with which the ends
of the band B are provided the arrangement being such that if the screws be
turned in one direction the band B will be "opened" and its diameter thereby
increased to enable the beading a of the case A to be slipped or inserted between
the rim C and the band B as shown in Fig. 1. The screws are then turned in the
opposite direction and the diameter of the band B is thereby decreased until
the edges a are gripped between the band B and the rim C as will be readily under-
stood by reference to Fig. 1.
For the purpose of "screwing up" the band B we provide the screws D with a
boss E which is formed with apertures e and the rim C of the wheel is formed
with an aperture c so that the boss E may be turned-say by means of a pin
or " tommy "from the spoke side of the rim.
We wish it to be understood that we do not confine ourselves to any particular
means for operating the right and left hand screws D nor do we confine ourselves
to the employment of particular means for tightening up the band B. Further,
the beading a may be made of cord, rubber, gut, coiled spring wire or any other
material sufficiently elastic to permit such edges or beading a being stretched over
the edges of the rim C. The band B may be made of metal or other suitable
material and such band may if desired be grooved, beaded, flat, corrugated, concave
or convex and the edges of said band may be turned upward so as to lie more snugly
against the edges of the case A and thereby be less likely to cut the material
of said case.
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:-
A pneumatic tyre held in the rim of the wheel by a band such as Radented

page_text: to be loosened or opened to permit the insertion of the elastic and beaded or enlarged
edges of said tyre or case said band B being also adapted to be tightened up so as
to grip said edges against the rim of the wheel all for the purposes and sub-
stantially as set forth.
