Improvements in Attaching Elastic Tyres to the Wheels of Cabs and
other Wheel Carriages.
We, JABEZ LONES and EDWARD HOLDEN, trading as Lones, Vernon and Holden,
of Sandwell Iron and Axle Works, Smethwick, in the County of Stafford, Manu-
facturers, do hereby declare the nature of this invention to be as follows:-
When the elastic tyres of cabs and other wheel carriages are attached to the
felly of the wheel great inconvenience arises when, under the influence of oblique
pressure the elastic tyre becomes detached from the trough shaped wheel rim by
which it was held. In order to replace the elastic tyre the wheel or vehicle and
tyre have to be taken to a coach builder or yard" where the tyre can be replaced
by a skilled workman.

Our invention consist in attaching elastic tyres to the wheels of cabs and other
vehicles in the manner hereinafter described, whereby a detached elastic tyre can
be readily replaced by the driver of the vehicle without the removal of the wheel,
and by the mere use of a spanner.
On the wooden felly of the wheel we fix in the usual way the ordinary iron tyre
on which in the finished wheel, the base of the elastic tyre bears. On each side
of the wooden felly we place a flat metallic ring the edges of which are turned
inwards. The said rings are attached to the felly by screw pins and nuts the
said pins passing through holes or lying in cross grooves, in the felly. The inner
turned in edges of the metallic rims engage in grooves in the opposite sides of
the felly. The parts are put together in the following manner.
The elastic tyre
being stretched and put on the metallic tyre, the metallic rings are placed on
each side of the felly, the outer turned in edges of said rings engaging in the
grooves or neck of the elastic tyre and fixing it in position, the inner edges of the
rings engaging in grooves in the sides of the felly. The screw pins are passed
through holes in the rings and through the holes, or in the cross grooves in the
wooden felly and screw nuts being screwed on to the screwed ends of the screw
pins the whole of the part are bound firmly together. By the greater or less
tightening of the screw pins and nuts any required pressure can be put on the
nech of the elastic tyre which is thereby held more securely than by the ordinary
construction.
In case of accidental detachment of the elastic tyre, the driver has only to relax
the screw nuts by means of a spanner so as to permit of the partial separation
of the rings when the elastic tyre can be replaced and refixed by the tightening
of the screw nuts.
The inner turned in edges of the rings and the grooves in the wooden felly in
which they engage may be dispensed with but we prefer to employ them as they
relieve the screw pins of pressure. One of the metallic rims may be made in one
piece with the ordinary iron tyre.
In a modification of our invention we make the metallic rim or tyre of the

page_text: wheel of a trough shaped figure and we make the elastic tyre with flanges at its
base, the said flanged base having a breadth equal to that of the trough in the
metallic rim or tyre. At opposite points in the vertical sides of the troughed
shaped metallic tyre slits are made.
The india rubber or elastic tyre is secured in position in the trough of the
metallic tyre by wireing in the following manner. Wire from a reel or bobbin is
wound several times round each of the flanges of the elastic tyre the ends being
fastened by being passed through the slits herein before referred to and twisted
together on the underside of the metallic tyre.

Improvements in Attaching Elastic Tyres to the Wheels of Cabs and
other Wheel Carriages.
We, JABEZ LONES and EDWARD HOLDEN, trading as Lones, Vernon and Holden,
of Sandwell Iron and Axle Works, Smethwick, in the County of Stafford, Manu-
facturers, do hereby declare the nature of our invention and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement: -
When the elastic tyres of cabs and other wheel carriages are attached to the
felly of the wheel, great inconvenience arises when, under the influence of oblique
pressure, the elastic tyre becomes detached from the trough shaped wheel rim by
which it was held. In order to replace the elastic tyre the wheel or vehicle and
tyre have to be taken to a coach builder or "yard" where the tyre can be replaced
by a skilled workman.
Our invention consists in attaching elastic tyres to the wheels of cabs and other
vehicles in the manner hereinafter described, whereby a detached elastic tyre can
be readily replaced by the driver of the vehicle without the removal of the wheel
and by the mere use of a spanner.
On the wooden felly of the wheel we fix in the usual way the ordinary iron tyre
on which, in the finished wheel the base of the elastic tyre bears. On each side
of the wooden felly we place a metallic ring the edges of which are turned
inwards. The said rings are attached to the felly by screw pins and nuts, or
screw pins only the said pins passing through holes, or lying in cross grooves, in
the felly. The inner turned in edges of the metallic rings engage in grooves in
the opposite sides of the felly. The parts are put together in the following
manner. The elastic tyre being stretched and put on the metallic tyre, the
metallic rings are placed on each side of the felly, the outer turned in edges of
said rings engaging in the grooves or neck of the elastic tyre and fixing it in
position, the inner edges of the rings engaging in grooves in the sides of the felly.
The screw pins are passed through holes in the rings and through the holes or in
the cross grooves in the wooden felly and screw nuts being screwed on to the
screwed ends of the screw pins, the whole of the parts are bound firmly together.
By the greater or less tightening of the screw pins and nuts any desired pressure
can be put on the neck of the elastic tyre which is thereby held more securely
than by the ordinary construction.
In case of accidental detachment of the elastic tyre the driver has only to relax
the screw nuts by means of a spanner so as to permit of the partial separation

page_text: of the rings, when the elastic tyre can be replaced and refixed by the tightening
of the screw nuts or screw pins."
Figure 1 of the accompanying drawing represents a portion of the periphery of
the wheel in elevation, and Figure 2 represents a cross section of the same on the
dotted line, a Figure 1, before the screw nuts of the fixing pins are screwed
home; and Figure 3 is a similar view to Figure 2 after the said screw nuts are
screwed home. Figure 4 is a slightly modified construction and arrangement of
the parts represented in Figures 1, 2 and 3.
The same letters of reference indicate the same parts in the several figures of
the drawing.
a is the wooden felly of the wheel which is provided with a metallic rim b
resembling the metallic tyre of an ordinary carriage wheel on which metallic rim
the india rubber or elastic tyre c seats itself. The said elastic tyre c is preserved
in position by the two lever like gripping rings d, d situated one on each side of
the wooden felly a and elastic tyre c. The said rings d, d have turned in
flanges d, d on their inner edges and a thickening or rib, d² taking in the
grooves in opposite sides of the elastic tyre c constituting the neck of the said
tyre. Annular grooves e, e are made in the opposite sides of the wooden felly a
for the reception of the flanges d¹, d¹ which flanges d, virtually constitute the
fulcrums of the lever like rings d, d. The gripping of the elastic tyre c is effected
by cross screw pins or bolts f, f and screw nuts g, g equidistantly arranged on the
wheel, which pins or bolts on being tightened cause the outer ribbed edges of the
gripping rings d d to approach each other (as will be best understood by reference
to Figures 2 and 3) and thereby grip with any desired force the india rubber or
elastic tyre c.
The lever like gripping rings d, d may be made in one piece or in two or more
pieces.
It will be understood that if, when in use, the tyre c under the influence of
oblique pressure becomes detached the outer edges ², of the rings d, d may
be opened out to such an extent (by the unscrewing of the screw nuts g, g of the
screw pins or bolts f, f) as to permit the easy replacement of the tyre, or the
introduction of a new tyre, the screw nuts g, g of the screw pins or bolts being
again screwed home for the securing of the replaced or new tyre on the wheel.
By providing the rings d, d with turned in flanges d', engaging in grooves e, e
in the sides of the felly of the wheel the screw bolts f, f are relieved of all pressure
and strain.
In the modified arrangement Figure 4, which is specially applicable to the
wheels of light broughams, and other light vehicles the screw nuts gare dispensed
with, screwed holes being made in one of the rings for the screw pins f to engage
with, and countersunk holes in the other for the heads of the screw pins f to
take in. By this arrangement there is an absence of projecting parts on the two
sides of the wheel. In Figure 4 the screw pins f are represented as occupying
crossing grooves in the periphery of the wooden felly instead of passing through
holes therein as is represented in Figures 1, 2 and 3.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that we claim
as our invention of "Improvements in attaching elastic tyres to the wheels of
cabs and other wheel carriages":
-:
First The combination with the metallic rimmed wooden felly of the wheel
of an elastic tyre, of a pair of lever like rings for gripping and holding the elastic
tyre in position on the wheel, the said lever like rings having inner flanged edges
taking in grooves in the wooden felly and also having outer thickened or ribbed
edges for engaging with the neck of the elastic tyre and cross screw pins and screw
nuts substantially as and for the purpose herein before described and illustrated in
the accompanying drawing.
Secondly; The modified construction and arrangement of parts represented in

page_text: Figure 4 of the accompanying drawing by which screw nuts are dispensed with,
screw pins alone being employed, the heads of which screw pins take in counter-
sunk holes in one metallic ring and the screwed ends in screwed holes in the
other metallic ring substantially as hereinbefore described and illustrated.
