Improvements in and connected with the Rims and Tyres of
Wheels for Cycles and other Vehicles.
I, REUBEN ('ORSHAM, of 69 Skinner Street, Bishopsgate, in the City of
London, Copying Machine Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in and connected with the rims and tyres
of wheels in which pneumatic or inflatable tyres are employed, and its chief object
is to provide means for retaining the pneumatic tube and its outer cover in or on
the rim of the wheel.
I make the rim of any suitable cross section such as concave, flat or convex for
example, and the surface against which the tyre is held or pressed may be smooth,
or more or less rough or irregular. Around the periphery of the rim, at or near
each edge thereof, I sometimes form a groove or channel, or a ridge or shoulder of
any suitable shape. These grooves, channels, ridges or shoulders may be provided
with eyes or be otherwise adapted to receive buttons, hooks, or other fastenings
attached to the tyre. The above mentioned roughness or irregularity of the
surface of the rim may be made in the material of the rim itself, or it may be
made in a separate piece of material secured to the rim.
I make the inner inflatable tube of the tyre in the usual way; but I make the
outer cover so that when its two free edges are brought together it assumes a form
corresponding more or less, at its inner circumference, to the section of the rim
with which it comes in contact.
For a concave rim the edges of the cover are so shaped and brought together as
to form a cover of more or less circular section, adapted to fit into the concavity
of the rim. For a flat rim the edges of the cover are flattened and brought
together so as to form a cover of more or less D shape, the straight part of the D
hearing against the outer periphery of the flat rim. For a convex rim the edges
of the cover are shaped to a reverse curve, and when brought together fit against
the convex curve of the rim.
At each edge of the cover I form or attach any desired number of transverse
strips forming tabs, tongues, or latchets, sufficiently long to reach from each edge
of the cover to the opposite edge of the rim when the tyre is in position and
inflated. These tabs, tongues or latchets may be made of any desired width,
and are placed on the edges of the cover at suitable distances apart, so that those
ou one edge of the cover fall into the spaces between those on the other edge of
the cover. The ends of these tabs, tongues, or latchets may be provided with any
suitable devices such as bolts, buttons, catches, clips or hooks by means of which
they can be secured to the edges of the rim, or in or to the grooves, channels,
ridges or shoulders formed thereon.
The parts of the cover which come into contact with the rim may be smooth, or
they may be made rough or irregular to prevent them from slipping on the
rim, and the irregularities or projections on them may be adapted to act as suckers
to retain the tyre on the rim.
I sometimes employ bands of indiarubber, or tape with or without indiarubber

page_text: inserted therein, which I pass round the cover and rim and fasten by hooks and
eyes, or other suitable devices in order to hold the cover and rim together during
the process of inflating the tyre. Or, I may employ spring clips passing round
the back of the rim and clasping the cover in any suitable way for the same
purpose.
The tyre is secured to the rim in the following way :-The inflatable tube is
laid in the cover, and the two edges of the latter are brought together, the tabs,
tongues, or latchets are laid in the spaces left for them on the opposite sides of the
cover. The inner tube is then slightly inflated, and the whole tyre is placed in
position in or on the rim, with the inflating valve passed through the hole in the
same, and the tyre is temporarily held in place, if necessary, by the hands or
spring clips above mentioned. The ends of the tabs, tongues, or latchets of the
cover are then connected to the edges of the rim by the fastenings attached to
them, the inflation is completed, and the temporary holding bands or clips
removed.
The ends of the tabs, tongues, or latchets may be provided with short tubes or other
thickening parts adapted to take a bearing against a shoulder, or some other suitably
formed part of the tin when the tyre is inflated, so as to retain the latter securely
in place. When hooks are employed for fastening the tabs, tongues, or latchets to
the rim they may be arranged to engage with the edges of the rim or with eyes or
shoulders formed therein or thereon. Spring buttons may also be employed for
fixing the tabs, tongues, or latchets to the rim, these may be made to engage with
the rim by pressing them into grooves, channels or holes formed therein, or bolts
may be passed through the tabs, tongues, or latchets and through the rim, or
through shoulders thereon, and be secured by nuts or otherwise.
The cover may also be secured to a rim having ridges or shoulders on it, by
means of spring clutches which clasp the said ridges or shoulders, and hold the
cover in place.
The cover may also be secured to the rim directly by means of buttons, clasps,
books or other suitable devices without the intervention of the tabs, tongues
or latchets.

Improvements in and connected with the Rims and Tyres of
Wheels for Cycles and other Vehicles.
I, REUBEN CORSHAM, late of 69 Skinner Street, Bishopsgate, in the City of
London, at present of 28 Kingsland Road, Shoreditch, London, Copying Machine
Manufacturer, do hereby declare the nature of this invention, and in what manner
the same is to be perforined, to be particularly described and ascertained in and by
the following statement :-
This invention relates to improvements in and connected with the rims and tyres
of wheels in which pneumatic or inflatable tyres are employed, and its chief
object is to provide means for retaining the pneumatic tube and its outer cover in
or on the rim of the wheel.
And in order that the said invention may be fully understood I will proceed to
describe the same with the aid of the accompanying sheet of drawings.
I make the rim of the wheel of any suitable cross section such as concave, flat,

page_text: or convex for ex umple, and with or without grooves or chaunels, or ridges or
shoulders of any suitable shape. These concave, Hat or convex rims, or the
grooves, chanuels, ridges or shoulders in or on them may be provided with eyes
or be otherwise adapted to receive buttons, hooks, or other tastenings for the
attachment of the tyre to the rim in the manner to be hereinafter described.
In Figures 1, 2 and 3 of the drawings the rims A are shown of concave, flat
and convex section respectively without grooves, channels, ridges or shoulders.
In Figures 4, 5, and 6, the rims A are shown of concave, flat and convex section
respectively with grooves or channels B formed therem.
In Figures 7, 8 and 9, the rims A are shown of concave, flat and convex section
respectively with ridges or shoulders C formed thereon.
I make the inner inflatable tube D of the tyre in the usual way; but
I preferably make the outer cover E so that when its two free edges are brought
together it assumes a form corresponding more or less, at its inner circumference,
to the section of the rim with which it comes in contact.
For a concave rim the edges of the cover are so shaped and brought together
as to form a cover of more or less circular section adapted to fit into the concavity
of the rim, as shown in Figures 1, 4 and 7. For a flat rim the edges of the cover
are flattened and brought together so as to form a cover of more or less D shape,
the straight part of the D bearing against the outer periphery of the flat rim, as
shown in Figures 2, 5 and 8. For a convex rim the edges of the cover are shaped to a
reverse curve, and when brought together fit against the convex curve of the rim,
as shown in Figures 3, 6 and 9.
At each edge of the cover I form or attach auy desired number of transverse
strips forming tabs, tongues or latchets F, (see Figure 10) sufficiently long to
reach from each edge of the cover to the opposite edge of the rim when the tyre
is in position and inflated. These tabs, tongues or latchets may be made of any
desired width and of any suitable material, and are placed on the edges of the
cover at suitable distances apart, so that those on one edge of the cover fall into
the spaces between those on the other edge of the cover. The ends of these tabs,
tongues, or latchets are provided with suitable devices such as hooks G
(Figures 1, 2, 3, 7, 8, and 9) buttons H (Figures 4, 5 and 6) bolts and nuts I
(Figure 11), or clips J (Figure 12), by means of which they can be secured to the
edges of the rim, or to the channels, ridges or shoulders formed therein or thereon,
as shown in the said figures.
The tyre is secured to the rim in the following way :-
The inflatable tube D is laid in the cover E, and the two edges E' E of the
latter are brought together, the tabs, tongues, or latchets F are laid in the spaces
left for them in the opposite edges of the cover E, as shown in Figure 10, which
is a view of part of a cover showing the inner circumference. The inner tube D
is then slightly inflated, and the whole tyre is placed in position in or on the
rim A, with the inflating valve passed through the hole in the latter in the usual
way. The ends of the tabs, tongues, or latchets F of the cover E are then
connected to the edges of the rim by the fastenings attached to them, as illustrated
in Figures 1, 2 and 3; to the grooves or channels B as illustrated in
Figures 4, 5 and 6; or to the ridges or shoulders C as illustrated in Figures 7,
8, 9 and 12 and the inflation of the tube D is then completed. The inflation
of the tube D tends to cause the cover E to expand laterally; but this expansion
is resisted by the hooks, buttons or other fastenings on the ends of the tabs,
tongues, or latchets F, which fastenings are engaged with the edges, grooves,
channels, ridges, shoulders or other parts, as the case may be, of the rim; and the
consequence is that the said fastenings are drawn into close contact with such
parts, and the tyre is thereby firmly secured to the rim.
The nature of the fastenings for connecting the tabs, tongues, or latchets to the
rim may be varied according to the shape of the latter, and the character of
the provision made thereon for the reception of the fastenings. When hooks are
employed they may be arranged to engage with the edges of the rim as shown in

page_text: Figures 1, 2 and 3 or with notches, holes, grooves, channels, ridges, shoulders or
other parts formed therein or thereon. Spring buttons similar to those used on
gloves may also be employed to engage in the grooves, channels, holes or other
suitable parts of the rim. In some cases the tabs, tongues or latchets may be
secured to the rim A by means of nuts and bolts I passing through both as
illustrated in Figure 11, or by means of spring clutches or clips made to grasp the
ridges or shoulders, as shown in Figure 12.
In Figure 1 of the drawings the section of the cover is drawn as if taken on
the line X-X of Figure 10, whilst in Figures 2, 3. 4, 5, 6, 7, 8, 9, 11 and 12 the
section of the cover is drawn as if taken on the line X-Y of Figure 10.
Similar letters of reference relate to like parts in all the figures of the
drawings.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. The method or means of securing the tyres to the rims of the wheels of
cycles and other vehicles, which consists in providing each edge of the outer cover
with a series of tabs, tongues or latchets adapted to pass across and to be secured
at the opposite edges of the rim, substantially as described.
Second. An outer cover for the tyre of a wheel for a cycle or other vehicle
provided with a series of tabs, tongues or latchets at each edge, the said tabs,
tongues or latchets at one edge being arranged opposite the spaces between the
tabs, tongues or latchets at the other edge and provided with suitable fastenings
whereby they can be attached to the rim, substantially as described.
Third. A rim for the wheel of a cycle or other carriage provided with grooves,
channels, ridges, shoulders, holes, notches or other parts adapted to receive the
fastenings of a series of tabs, tongues, or latchets connected with the outer cover
of the tyre for the purpose of securing the tyre to the rim, substantially as
described.
