PROVISIONAL SPECIFICATION.
Improvements in Velocipedes and Light Road Vehicles.
I CHARLES STEPHENSON of 82 Middle Street South, Driffield, in the County
of York, Cycle Agent, do hereby declare the nature of this invention to be as
follows:-
There are many methods of and means for securing pneumatic tyres to the wheels
of road vehicles several of these being by the use of endless wires or bands and my
invention is intended to provide a rim of peculiar shape or form adapted to receive
endless wires or bands of metal for the purpose of securing the outer cover of a
pneumatic tyre thereto.
In carrying out my invention I provide a metallic rim of a peculiar section and
form, said rim being semicircular or nearly so in outline and having a sunk flat
bearing surface with a flange at either side throughout the greater part of its
circumference or periphery, but having on one side for a short distance, say about
one sixth of its circumference, a sunk triangular (or equivalent) groove or hollow
extending downwardly, the base of said triangle forming part of and coincident
with the bearing surface and capable of receiving a shield or filling-in piece after
the tyre cover is in position.
I secure in any well known manner to each side or edge of the outer cover an
endless wire or band of circumference or length to fit accurately when in position
round the bearing surface of the rim.
To secure the tyre I place a portion of the edge of said tyre with its endless wire
over and into the triangular hollow or groove on the one side of the rim and then
pass the rest of the wire over the bottom or opposite part of rim when the wire may
be lifted and passed on to the centre of the periphery and pushed up against the
flange. The other side or edge and its wire is then placed in the groove and
similarly treated. The shield or filling-in piece may then be inserted and, if
desired, secured by means of a bolt or catch at one end and a bevelled edge at the
other or other similarly effective means, and the inner air tube (which will previously
have been placed in position) inflated and when said inflation is completed the edges
of the outer cover with their controlling wires will be forced against the outer
flanges and the tyre firmly secured to the rim.

manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:—
There are many methods of and means for securing pneumatic tyres to the wheels

page_text: of velocipedes and other road vehicles amongst others by means of endless wires or
bands and my present invention consists mainly of a rim of peculiar shape or
section in one part of such rim adapting it to receive endless wires or bands for the
purpose of securing the outer cover of a pneumatic tyre thereto.
In describing my invention I shall refer to the accompanying sheet of drawings
and to the figures and reference letters thereon
Figure 1. is a section of main portion of the rim.
Figure 2. a section of the minor portion thereof hereafter described.
Figure 3. is the same with the shield or removable filling in piece in position.
Figure 4. a section of shield or filling in piece or block.
Figure 5. shews the tyre deflated with one portion of the length of endless wire
in recess either immediately before removal or during the act of getting it upon the
rim over the flange thereof.
Figure 6. is a similar view but shewing the wire after same has been lifted over
flange or rim and pushed towards centre so as to allow of the filling in block being
inserted immediately before inflation of tyre.
Figure 7. shews tyre fully inflated and endless wires tightly pressed against
flanges of rim thereby securing said tyre.
In carrying out my invention I provide a metallic rim preferably of section
shewn in Figure 1. and being semicircular or nearly so in its lower portion A and
having a flat bearing or upper portion B with side flanges such as C. C¹ and this
form or section continues throughout the greater portion of the circumference or
periphery of the rim but I form on one side of said rim and in or through a small
portion of the periphery say one sixth thereof a sunken groove or hollow D which
may be triangular or nearly so in section and as shewn by Figure 2. the base of
said triangle forming part of and being coincident with the bearing surface B.
This hollow D is capable of receiving a short filling in piece or block Figure 4
after the wire has been passed over the flange of the rim and before inflation.
1 secure in any well known manner to each side or edge of the outer cover E. of
the air tube F. Figs. 5. 6. 7. an endless wire or band G. G¹ of circumference or
length to fit accurately when in position round the bearing surface or periphery B
of the rim.
To secure the tyre to the rim I place a portion of one edge of the outer cover
with its endless wire over and into the triangular recess D. the remaining portion
of the edge and wire may then be easily passed over the opposite part of the flange
and the whole may then be pushed across the bearing surface B and close up to
opposite flange C. Fig. 5. the air tube F may now be passed over the flange by
reason of its elasticity and placed in position as shewn Figs. 5. 6. 7. the opposite
edge of cover E with its wire is then taken in hand and part of its length placed
in the hollow as shewn by G Figure 5. and after the remaining portion has been
passed over opposite part of flange it is pushed towards the centre as shewn in
Figure 6 so permitting of the filling in piece or block Figure 4. being put into
position as in Figures 3. and 7. The tyre is now ready for inflation and when
fully charged the wires G. G¹ are pressed tightly against the flanges C. C¹
Figure 7. and the tyre held securely in position.
The filling in piece or block may be fastened by means of a bolt or catch or in
any desirable manner and I do not bind myself to the shape of either the recess or
hollow D. or that of the filling in piece or block.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1
1. For securing (or enabling to be secured) the endless wires or bands attaching
pneumatic tyres to the rims of road vehicles a rim having in a portion of its
periphery a sunken hollow such as D. and flanges such as C. C¹ in combination
with a filling in piece or block such as shewn by Figure 4. substantially as and for
the purposes described and with reference to the accompanying drawings.

page_text: 2. The method of and means for securing pneumatic tyres to the rims of road
vehicles substantially as herein before described and as illustrated by the accom-
panying drawings.
