Improvements in or pertaining to the Tyres and the Felloes of the
Wheels of Road Carriages.
I GEORGE WATERS TARVER of The Glen Glen Eldon Road Streatham in
the County of Surrey Engineer do hereby declare the nature of this invention
to be as follows:-
The object of my invention is so to construct and fit the tyres and the
felloes of the wheels of road carriages of all descriptions whether broughams
landaus cabs coaches or such like vehicles or velocipedes that the tyres can
easily and quickly be secured in position while the great evil that is experienced
in those carriages that have pneumatic and collapsible tyres in that if the tyre
collapses the wheel cannot be used until the tyre has been repaired or renewed
and restored will be entirely obviated.
To carry out this object the felloe of the wheel may be made in any customary
manner and style whether solid or hollow and of any suitable material whe: her
metal or wood or otherwise and the outer periphery of this felloe is flat in
transverse section. On each of the lateral sides of this felloe is or may be formed
or thereto is or may be fitted a gutter created by any suitable separate or other
devices the outer lip or edge of which gutter is about on a level with the outer
periphery of the felloe and these gutters may extend all round the wheel and i
each gutter can be placed and secured a long bar or plate or tube or similar
appliance so formed and constructed that while the one longitudinal part thereof
fills the gutter the other stands so far thereout and projects so far beyond the outer
periphery of the felloe as to constitute and form a Hauge to and for such felloe on
each side. Instead of using a gutter wherein to place. and secure the flange these
flanges may be secured directly to the felloe by transverse bolts and nuts or the
like which bolts would pass through the felloe and the flange on each side. The
flange may be formed in one length or may be divided into two or more lengths in
either case the ends when such flange is placed in position round the wheel being if
desired secured together in any usual or other manner. One flange also on one side
of the felloe may be a fixture while only the other is removable.
On and round the outer periphery of the felloe between the two flanges is placed
a long block or core which may be nearly as broad as the felloe and is so thick or
stands so far off the felloe that its outer periphery is about on a level with the outer
edges of the flanges and this block or core may be endless in which case it can be
slipped on and round the felloe when one or both of the flanges has or have been
removed or the ends thereof can be connected together when it has been placed
in position round the wheel in any suitable manner and by any usual devices.
This block or core may be made wholly of metal or it may even be of wood
in several sections or it may consist of a metal or other shoe provided with a
face of india rubber or the like with a canvas or other backing if desirable
and whatever material or materials may be used in the construction of this
block or core it may be solid or hollow or longitudinally duplicated as may be
preferred. When the face of this block is made of india rubber or the like
mounted in a shoe it may if desired be formed and made in a manner and of
a shape similar to the ordinary solid or hollow compressible or noiseless tyre
and may project so far beyond the outer edges of the flanges as may be
dosized

page_text: To adapt to and use with this felloe so constructed and fitted a pneumatic
tyre the ordinary pneumatic tube can be placed round and outside of the felloe
and of the block or core thereupon and any suitable india rubber or other cover
for this tube or tyre may be placed over the tube. The lateral edges of this
tyre enter between the central block or core and the flanges on both sides and
these edges of the tyre may be fitted with endless or other wires or may be
enlarged or may be otherwise so fitted in any usual or other manner that they
will be securely clasped or retained between the central block or core and the
flanges to increase which security it is very convenient to bend the outer edges
of the flanges inwardly towards each other and also to form the block or core
broader at the level corresponding to that of the outer edges of the flanges
than at its base on the outer periphery of the felloe of the wheel whereby in
transverse section two enlarged recesses will be created between the central
block or core and the flanges on both sides wherein the enlarged edges of the
tyre will be retained. The edges of the tyre can also be securely clasped
between the central block or core and the flanges when as aforesaid transverse
bolts are used to secure these flanges by tightening the nuts or the like on such
bolts or otherwise.
This pneumatic tyre therefore very obviously can be placed on and round
this wheel in the ordinary manner and when the flanges are secured in position
the lateral edges of the cover will be securely held and the tyre will be properly
retained in its proper position. But when this tyre through accident mis-adventure
or otherwise collapses it can easily be removed and when the flange or flauges
has or have been replaced the wheel can still be used as the central block or
core can and will act as a tyre being kept in position and it may be assisted
in such action by the flanges.

J, GEORGE WATERS TARVER of The Glen Gleneldon Road Streatham in the
County of Surrey Engineer 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 so to construct and fit the tyres and the felloes of
the wheels of road carriages of all descriptions whether broughams landaus cabs
coaches or suchlike vehicles or velocipedes that the tyres can easily and quickly be
secured in position while the great evil that is experienced in those carriages that
have pneumatic and collapsible tyres in that if the tyre collapses the wheel cannot
be properly used until the tyre has been repaired or renewed and restored will be
entirely obviated.
To carry out this object the felloe of the wheel may be made in any customary
manner and style whether solid or hollow and of any suitable material whether
,metal or wood or otherwise and the outer periphery of this felloe is flat in transverse
section. On each of the lateral sides of this felloe is or may be fitted a flange
projecting above the level of the outer periphery of the felloe and these flanges
may be secured directly to the felloe by transverse bolts and nuts or the like which
bolts would pass through the felloe and the flange on each side.
The flange may be formed in one length or may be divided into two or more"
lengths. On and round the outer periphery of the felloe between the two-flanges

page_text: is placed a long block or core which may be nearly as broad as the felloe or of any
suitable breadth as may be convenient and which is so thick or stands so far or so
much off the felloe that its outer periphery is about on a level with but preferably
extends beyond the outer edges of the flanges and this block or core may be endless
in which case it can be fitted on and round the felloe when one or both of the
flanges has or have been removed or the ends thereof can be connected together
when it has been placed in position round the wheel in any suitable manner and by
any usual devices. This block or core may be wholly of metal in several sections
or it may consist of a metal or other shoe provided with a face of india rubber, or
the like it may be solid or hollow or longitudinally duplicated as may be preferred
and may project so far beyond the outer edges of the flanges as may be desired and
this block or core may be so fitted as to prevent its lateral or other movement on
the outer periphery of the felloe if desired.
To adapt and use with this felloe so constructed and fitted a pneumatic tyre the
ordinary pneumatic tube can be placed round and outside of the felloe and of the
block or core thereupon and any suitable india rubber or other cover for this tube
or that is to say any tyre may be placed over the tube.
The lateral edges of this tyre enter between the central block or core and the
Hanges on both sides and these edges of the tyre may be fitted with endless or other
wires or may be enlarged or may be otherwise fitted in any usual or other manner
so that they can be securely clasped or retained between the central block or core
and the flanges.
My invention will be fully understood by further describing same with reference
to the accompanying drawings whereon
Fig. 1 is a transverse section showing a felloe adapted for vehicles such as cabs
coaches and the like fitted with an ordinary pneumatic tyre the lateral edges of the
protective cover of which tyre are fitted with endless wires or are by any other
suitable means rendered non-extensible.
Fig. 2 is a transverse section showing modified form of felloe illustrated in
Fig. 1.
Fig. 3 is a transverse section of felloe constructed eutirely of metal with rubber
core.
Fig. 4 is a side elevation of a felloe and tyre showing method of removing a tyre
the lateral edges of which are non-extensible.
Fig. 5 is a transverse section of a felloe showing flanges adapted for use with tyre
the lateral edges of which are enlarged and may be extensible.
Referring to Figures 1. & 2. A is the wooden rim or felloe of the wheel which may
B. B. arc
if desired be fitted with an ordinary metal tyre A' as shown in Fig. 1.
the side flanges between which and the core C. are shown the inextensible edges F. F.
of the protective cover E.
In Fig. 2 the core C. is shown of less breadth than the felloe and consists of a
metal shoe with india rubber filling.
In Fig. 3 is shown a section of a felloc suitable for light vehicles. The core C.
being of rubber in a metal shoe C¹ the flanges B. B. being formed of L section
are secured to the core by the bolts G. G. passing through slots in the flanges H. H.
which allow of lateral adjustability of the flanges and enable them to be closed on
the edges of the protective cover F. F. or on the core C. when the pneumatic tyre
has been removed.
In Fig. 4 is shown a convenient method of removing from or attaching to the
felloe a pneumatic tyre baving a protective cover with inextensible edges. After
the removal of one or more of retaining bolts B' the segment B₁ may be drawn
aside the remaining bolt B³ acting as an axis.
The tyre is by this means allowed to assume a position excentric to the felloe
and is easily removed therefrom.
In Fig. 5 is shown a section of felloe adapted for use with a pneumatic tyre the
lateral edges of the protective cover of which are fitted with thickened edges which
may be extensible. In this case the core C. may be fitted round the felloe-in-such

page_text: a manner as to be capable of lateral movement thereon and this core is preferably
broader at or about the level corresponding to that of the outer edges of the
flanges which outer edges are preferably bent inwardly towards each other.
The flanges B. B. may be secured to the felloe by transverse bolts passing through
both flanges and the felloe or the flanges may be secured to the felloe separately
by bolts or the like.
To adapt and use with this felloe a pneumatic tyre having thickened edges the
bolts or the like are slackened and the thickened edges of the protective cover F. F.
are placed round the felloe between the core and the flanges the bolts are then
tightened and the tyre is firmly attached to the felloe.
Similar letters of reference refer to like parts in all figures.
In most cases it is convenient to fit a ring or strip of rubber or it may be of
metal or any suitable material between the flanges and the core when the pneumatic
tyre has been removed from the felloe particularly when the core is capable of
lateral movement thereon as these rings or strips will tend to keep the core equi-
distant between the two flanges.
It is also convenient to insert a strip of canvas or rubber or other suitable
material and shape between the core and the pneumatic tube to prevent friction aud
damage to the latter.
It is obvious that when this pneumatic tyre is damaged through accident or
otherwise collapses it can easily be removed and when the flanges or sections of
same have been replaced or resecured the wheel can still be used as the central
block or core can and will act as a tyre.
I am aware that removable rings or flauges in sections or otherwise to retain a
protective cover in position are not broadly new.
I am also aware that it is not new to fit a block or core between fixed flanges for
a similar object.
I am not however aware that two removable or adjustable side flanges employed
in combination with a block or core and a protecting cover of a pneumatic tyre
have been proposed as herein described and whereby the pneumatic tyre may be
removed and leave a wheel suitable for road travelling.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I claim
as my improvements in or pertaining to the tyres and the felloes of the wheels of
road carriages is :—
The combination with a protective cover of a pneumatic tyre the lateral edges of
which may be extensible or inextensible such as the covers E E. of a felloe such
as the felloe A. having a projecting detachable or adjustable flange such as the
flanges B. on each of the lateral sides of such felloe and a block or core such as the
core C. round the outer periphery of such felloe between the flanges whereby
the removal of the pneumatic tyre renders the wheel capable of travelling on the
block or core substantially as set forth.
