Improvements in or connected with Inflated or Paeumatic Tyres for
the Wheels of Road Vehicles.
I, WILLIAM EDWARDS of "The Lindens," Cosbycote Avenue, Herne Hill, in
the County of London, Cyclist, do hereby declare the nature of this invention to be
as follows:-
The object of my invention is to so construct, arrange and combine the parts
composing inflated or pneumatic tyres and means for their attachment to the
wheels of road vehicles. as hereafter described, whereby I am enabled to fit or
adapt such tyres to road wheels having an ordinary or usual wood or other felloe
and plain iron rim, without alteration of such wheels, and in such manner that
should the inflated or pneumatic tyre become damaged for example, it can be
removed from the wheel with great facility and without the necessity of skilled
assistance or special tools, and when so removed the wheel may be run and used on
the road, in the ordinary way, and also when fitted with the inflated tyre, the latter
is prevented coming in contact at its outer sides with curb stones or the like by
the arrangement or construction of the tyre fixings.
According to my invention I attach to each side of the wood or other felloe of
the wheel to be fitted, a metal ring, fixed by screws, rivets, bolts or the like ;
this ring is of such section as to form a channel, opening towards the periphery of
the wheel, the ring forming a wall on the outer side while the felloe forms the
opposing wall, the section of the ring then takes inwards and fits against the felloe
to which it is affixed as aforesaid. The part of the ring forming the outer wall of
the channel is bent at its upper edge towards the wheel felloe, whereby the peri-
pheral opening of the channel is somewhat contracted and the interior of the outer
wall is inclined away from the felloe. The peripheral edges of the rings are
arranged to come below or even with the usual flat metal tyre of the road wheel,
and thus a wheel fitted with the rings may be run on the road without inconve-
nience, when the pneumatic tyre is removed therefrom. In some cases the rings
may be made in segments and fixed as aforesaid to the felloe. At one part (or
parts if preferred) I divide each ring by making a small length of same removable
say for example three inches in length although I do not limit myself to this
dimension, and this movable section may be retained in position by bolts taking
through slots in the movable part whereby upon the bolts being loosened the part
may be slidden from position ; in some cases to facilitate ready removal and
replacement the movable part may be hinged or may be retained by keyhole
slots and fixed bolts, or by slots and bolts with turnable heads, or arranged
to slide in guides or by other suitable means this part may be readily
detachable.
The tyre proper is composed of the usual parts, as an air tube and outer cover,
and the outer cover is fitted with wires in its outer edges; the wired edges are
passed into the ring channels, and the movable section having been previously
detached, the two ends of the wires are drawn together at that part and connected
by any usual or convenient means and the movable section is then replaced in
position and the tyre inflated. The inflation causes the tyre cover to be drawn
tightly against the inwardly inclined edges of the rings to make a watertight joint

page_text: and canvas flaps or cushions in the interior of the outer cover may be fitted to
come between the edges of the iron rim of the road wheel and the inner air
chamber.
The metal rings are formed so that their outer lateral surfaces come beyond
the sides of the pneumatic tyre (when inflated) and do not allow the said tyre
to be brought into contact with curbstones or the like. The outer surface of the
rings need not necessarily follow the contour of the inner formation of the
channel.
By my invention, among other advantages, I am enabled to fit a pneumatic
tyre to a road wheel as now in common use with carriages, hansom cabs and
other vehicles, in a more ready and convenient manner than heretofore, and
without alteration to the wheels and also enable such tyres to be readily
detachable.
CUMI UMID SI MUITIUATION.
Improvements in or connected with Inflated or Pneumatic Tyres for
the Wheels of Road Vehicles.
I, WILLIAM EDWARDS of "The Lindens" Cosbycote Avenue, Herne Hill, in
the County of London, Cyclist, 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 :—
The object of my invention is to so construct, arrange and combine the parts
composing inflated or pneumatic tyres and means for their attachment to the
wheels of road vehicles as hereafter described, whereby I am enabled to fit or
adapt such tyres to road wheels having an ordinary or usual wood or other felloe
and plain iron rim, without alteration of such wheels, and in such manner that
should the inflated or pneumatic tyre become damaged for example, it can be
removed from the wheel with great facility and without the necessity of skilled
assistance or special tools, and when so removed the wheel may be run and
used on the road in the ordinary way, and also when fitted with the inflated
tyre, the latter is prevented from coming in contact at its outer sides with
kerb stones or the like by the arrangement or construction of the tyre
fixings.
In order that my invention may be readily understood I will describe same by
reference to the accompanying drawing, whereon at
Figure 1 is shown in sectional perspective view a part of a pneumatic tyre and
wheel felloe arranged and combined according to my invention,
Figure 2 being a side elevation of a wheel, drawn to a smaller scale, and so
fitted, and
Figures 3 to 9 inclusive are detail views of parts hereafter referred to.
Similar letters of reference indicate like parts in the several figures.
According to my invention I attach to each side of the wood or other felloe A.
Figure 1 of the wheel to be fitted, a metal ring B fixed by screws C, rivets, bolts,
or the like this ring B is of such section as to form a channel, opening towards
the periphery of the wheel, the ring forming a wall on the outer side while the
felloe A forms the opposing wall, the section of the ring then takes inwards and
fits against the felloe to which it is affixed as aforesaid. The part of the ring B
forming the outer wall of the channel may, if desired, be bent at its upper edge
towards the wheel felloe somewhat as shown by the sectional view Figure 3
whereby the peripheral opening B' of the channet somewhat contracted and the,

page_text: interior of the outer wall is inclined away from the felloe. The peripheral edges
of the rings B are arranged to come below the tread of the usual flat metal tyre D
of the road wheel, and thus a wheel fitted with the rings may be run on the road
without inconvenience when the pneumatic tyre is removed therefrom. In some
cases it is convenient to make the rings B in segments and fixed as aforesaid to the
felloe A. At one part (or parts if preferred) I divide each ring B to make a
suitable length such as B of same removable say for example as shown at Figure 2
although I do not limit myself to this dimension; and this movable section B² may
be retained in position by bolts or screws C as shown. If desired the bolts may
pass through slots B' in the movable part say as shown at Figure 4 whereby
upon the bolts being loosened the part B₂ may be slidden from position; in
some cases to facilitate ready removal and replacement, the movable part B* may
be hinged as shown at Figure 5 or may be retained by keyhole slots B³ as at
Figure 6 and fixed bolts, or by slots and bolts with turnable heads as at
Figure 7, or by other suitable means this part B may be made readily
detachable.
The tyre proper is composed of the usual parts, as an air tube E Figure 1 and
outer cover F, and the said outer cover F is fitted with wires G in its outer edges;
the wired edges of the outer cover F are passed into the ring channels on the
outside of the wheel felloe, and the movable section B having been previously
detached, the two ends of the wires G are drawn together at that part and
connected by any usual or convenient means, such as by the ends of the wires G
being screw threaded to take into a screwed sleeve H as shown at Figure 8, or the
ends of the wires may be joined by terminal hooks H as shown at Figure 9, or the
ends may be brazed, or otherwise the wires may consist of endless rings, when
the tyre is applied to the wheel by the removal of a section B' as at Figure 2
which latter is replaced after the wired edges of the outer cover F have been
adjusted into position in the channels; the air tube E is placed within the hollow
of the outer cover before the latter is adjusted and secured within the channels
and the inner tube may then be inflated by means of the valve or valves as
nsual. The inflation causes the tyre cover to be drawn tightly against the edges
of the rings B to make a watertight joint and canvas flaps or cushions in the
interior of the outer cover may be fitted if desired, or found necessary, to come
between the edges of the iron rim D of the road wheel and the inner air
chamber E.
The metal rings B are or may be formed so that their outer lateral surfaces come
beyond the sides of the pneumatic tyre (when inflated) and do not allow the said
tyre to be brought into contact with kerbstones or the like say as shown at Figure 3
and the outer surface of the rings need not necessarily follow the contour of the
inner formation of the channel.
By my invention, among other advantages, I am enabled to fit a pneumatic
tyre to a road wheel as now in common use with carriages, hansom cabs and
other vehicles, in a more ready and convenient manner than heretofore, and
without alteration to the wheels and also enable such tyres to be readily
detachable.
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 as my improvements in or connected with inflated or pneumatic tyres for the
wheels of road vehicles is as follows:-
1. The combination with an ordinary wheel felloe and its metal rim, of metal
rings attached on each side of the felloe to form channels, their peripheral edges
located below the metal rim, and a segment of each ring made removable, an inner
air tube, an enclosing outer cover with retaining wires to be located outside the
felloe and inserted and secured in the channels upon the displacement of the
removable segment, and the latter refixed, all substantially as and for the purposes
herein before described.

page_text: 2. The combination with the ordinary wheel felloe and its metal rim, the air
chamber E, and the elastic cover F having the joined or endless wires G G applied
on each external side surface of the wheel felloe; of rings forming channels arranged
below the metal rim and fixed to the wheel felloe on each side, to retain the wires
in position, and removable segments whereby the wires may be adjusted and
detached into or from the channels all substantially as set forth.
3. The combination with an ordinary wheel felloe and its metal rim, of the
metal rings made in sections or otherwise, and applied to each side of the wheel
felloe to form channels whose peripheral edges come below the metal rim of the
wheel substantially as described and shown by Figures 1 and 3 in combination
with a removable or displacable segment, constructed and arranged substantially
as described with special reference to Figures 2, 4, 5, 6 and 7 of the accompanying
drawings.
