Improvements in Wheels for Vehicles.
We, ROBERT RINTOUL SYMON, of 20, Abchurch Lane, in the City of London,
Gentleman, and HENRY ALONZO HOUSE, Junr., of East Cowes, in the Isle of Wight,
Engineer, do hereby declare the nature of this invention to be as follows:
The improvements which form the subject of the present invention are more
especially applicable to motor-car wheels, but wheels constructed in accordance
with this invention may also be used for other vehicles.
The hub of the wheel is preferably formed of a metal casting with sockets or
recesses to receive the inner ends of the spokes which are preferably of wood and
fitted at their outer ends with separate metal sockets or ferrules.
An inner
metal tyre is shrunk direct on to the wheel thus partly formed, the inner side
of such tyre bearing on the outer end of each of the sockets or ferrules which
may be flanged to receive, the same, and the two may be further held together
by means of rivets or otherwise. It will thus be seen that each spoke bears at
its inner end on the metal hub and at its outer end on the inner circumference
of the inner tyre. This inner tyre may be provided with lips or flanges pro-
jecting circumferentially outwards and serving to keep in place the wooden
felloes which are fitted to the said inner tyre. The outer circumferential surface
of the felloes is enclosed in an outer metallic tyre which may be shrunk on in
the ordinary way, or may be in any convenient number of separate segments
with spaces between, and held in place by rivets passing through the said outer
tyre, the felloes, and the inner tyre.
Instead of employing wooden felloes as above described, we sometimes sur-
round the outer circumference of the inner tyre with blocks of indiarubber or
other like resilient material, held in place by an outer metal tyre formed of
separate trough-like segments so shaped and fitted that they enclose the said
indiarubber blocks, holding the same more or less loosely to the inner tyre, and
at the same time allow the said blocks to form a resilient cushion between the
inner and outer metal tyres. The outer tyre segments and the indiarubber
blocks are held more or less loosely in place by inwardly projecting flanges on
the sides of the said trough-like segments, which flanges take under the edges
of the inner tyre, and to enable these trough-like segments to be placed in
position their sides may be sprung or bent open sufficiently for the flanges thereon
to pass the inner tyre, and afterwards sprung or bent inwards again. Or a gap
may be made in one portion of one side of the inner tyre, so as to enable the
flanges on one side of each of the segments of the outer tyre to pass into place.
The segments may thus be threaded into position, one after the other, and the
beforementioned gap may be filled up by a keeper-piece when the whole of the
said segments are in position.
Or the flanges of the trough-like segments may in some cases project outwardly
and the whole of them be kept in position by a flanged keeper-ring on each side
thehool

page_text: The adjacent edges of the outer circumferential portions of the trough-like
segments are preferably so shaped by halving together for example that the load
on the wheel is transferred from one such segment to another in as continuous
and regular a manner as possible.
The indiarubber or other resilient blocks are so shaped as to allow the same
to be compressed and also to prevent any rattle or jar of the metallic parts
whether the said blocks are under compression or not.

Improvements in Wheels for Vehicles.
We, MARTHA ANN SYMON, of 14, Park Street, Park Lane, London, Widow,
and ERNEST CASSEL, K.C.M.G., of 48, Grosvenor Square, London, Gentleman,
Executors of Robert Rintoul Symon, Deceased, late of 20, Abchurch Lane, in
the City of London, and HENRY ALONZO HOUSE, Junior, of East Cowes, in the
Isle of Wight, Engineer, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:
The improvements which form the subject of the present invention are more
especially applicable to motor-car wheels, but wheels constructed in accordance
with this invention may also be used for other vehicles.
In the accompanying drawings, Figure 1 is a side elevation, partly in section,
of so much of a wooden-felloed wheel as is necessary to illustrate this invention,
Figure 2 is a transverse section of Figure 1 and Figure 3 is a similar section
illustrating a modification in the tyre portion of the wheel. Figure 4 is a side
view of a portion of a wheel with indiarubber or other suitable resilient material
interposed between the inner and outer tyres as hereinafter more fully described,
Figures 5 and 6 are sections on lines A A and B B respectively of Figure 4,
Figure 7 is a plan view of Figure 4, Figure 8 illustrates the shape of the india-
rubber or other resilient material before referred to, and Figures 9, 10, 11,
12 and 13 illustrate modifications in the tyre portion of the wheel. Similar
letters of reference relate to like parts in each of the figures of the drawings.
The hub of the wheel is preferably formed of a metal casting a (Figures 1 and 2)
which may be hollow as shewn so as to form an oil reservoir w from which oil
may be conducted to the journal through holes. The hub is also provided with
sockets or recesses to receive the inner ends of the spokes which are preferably
of wood and adapted to bear against one another as shewn in Figure 1. c is, a
cover plate or cap secured to the metal hub casting by bolts d passing through
the spokes at their joints as shewn in Figures 1 and 2. The spokes bare furnished
at their outer ends with separate metal sockets or ferrules e, and an inner metal
tyre f is shrunk direct on to the wheel thus partly formed, the inner side of such
tyre bearing as shewn on the other end of each of the sockets or ferrules e which
may be flanged to receive the same, and the two may be further held together, by
means of rivets.g or otherwise. It will thus be seen that each spoke 6 bears at
its inner end on its two adjacent spokes and on the metal hub a, and at, its
outer end on the socket e which bears on the inner circumference of the inner

page_text: tyre for they may bear direct upon the said inner circumference of the tyre f.
This inner tyre may be provided with lips or flanges projecting circumferentially
outwards as shewn at h and serving to keep in place the wooden felloes i which
are fitted to the said inner tyrė f. The outer circumferential surface of the
felloes is enclosed in an outer metallic tyre ; which may be shrunk on in the
ordinary way, or may be in any convenient number of separate segments' with
spaces between, and held in place by rivets passing through the said outer tyre j,
the felloes i, and the inner tyre f, as at k for example. In some cases the lips
or flangesh on the inner tyre f may be dispensed with as shewn in Figure 3.
Instead of employing wooden felloes as in Figures 1, 2 and 3 the outer circum-
ference of the inner tyre f may be surrounded with blocks of indiaŕubber or
other like resilient material i (Figures 4 to 13) held in place by an outer metal
tyre formed of separate trough-like segments j so shaped and fitted that they
enclose the indiarubber blocks i holding them more or less loosely to the inner
tyre and allow the said blocks to form a resilient cushion between the inner
and outer metal tyres f and j. The outer tyre segments ; and the indiarubber
blocks are held more or less loosely in place by the inwardly projecting lips or
flanges m on the sides of the trough-like segments which flanges m take under
the edges of the inner tyre f as shewn in Figures 5, 6 and 7.
Or instead of the lips or flanges m, studs or projections may be formed on the
inner surface of one side of each of the trough-like segments as shewn at n in
Figures 10 and 11, the other side of such segment being provided with a lip or
flangem as shewn in the same figures.
In order to enable the segments j to be placed in position their sides may be
sprung or bent open sufficiently for the lips or flanges m to pass the inner tyref,
and afterwards sprung or bent inwards again, as indicated at the right hand side
of Figure 5 for example.
Or a gap be made in one portion of one side of the inner tyre f, (see
Figures 4, 6 and 7) so as to enable the lips or flanges m on one side of each of the
segments j to pass'into place. The segments ; may thus be threaded into position,
one after the other, and the beforementioned gap may be filled up, after the whole
of the segments j are in position, by a keeper-piece o bolted to a bracket p
rivetted to the inner tyre f..
Or the lips or flanges of the segments may in-some cases project outwardly
as shewn at q in Figure 9, and the whole of them be kept in position by a flanged
keeper-ring on each side of the wheel.
The adjacent edges of the circumferential portions of the trough-like segments j
may be so shaped by halving together; as shewn at s in Figure 4 for example,
that the load on the wheel is transferred from one such segment to another in
as continuous and regular a manner as possible.
The indiarubber or other resilient blocks i are so shaped as to allow the same
to be compressed and also to prevent any rattle or jar of the metallic parts
whether the said blocks are under compression or not. Such a shape is indicated
in Figure 8, but same may be modified or varied as desired.
Projections u (Figures 10 and 11) are sometimes provided on the inner surface
of each of the trough-like segments ; coincident with and entering more or
less into the holes t in the indiarubber or other resilient cushion in order to
more or less preserve the relative positions of the segments round the circum-
ference of the wheel. Or in some cases stop-pieces v may be rivetted to the inner
tyre f as shewn in Figures 12 and 13 which are respectively sectional elevation
and transverse section of the tyre portion of a wheel. These stop-pieces v come
between the trough-like segments ; which latter are furnished with lugs or
ears w carrying pins on which are threaded tubes or sleeves y of indiarubber
or other suitable material which tubes or sleeves bear against the stop-pieces v
and tend to neutralize any jar or noise caused by the movement of the seg-
ments j, and also preserve the relative positions of the said segments round the
circumference of the wheel.

page_text: Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is: -
First. The improvements in motor-car and other wheels which consist in
mounting the spokes. 6 so that the sides of their inner ends bear against one
another and are encased in a recess formed in the metal hub a, furnishing their
outer ends with sockets or ferrules e adapted to receive an inner tyre f, and
providing a cushion j of more or less resilient material i between the said inner
tyre f and the outer tyre or tread. j, substantially as described with reference to
the drawings.
Second. In motor-car and other wheels the combination of an inner tyre f
and an outer tyre j with more or less resilient material i between the two, the
whole arranged and operating substantially as described with reference to the
drawings.
Third. In motor-car and other wheels the combination of an inner tyre f, an
outer tyre consisting of separate trough-like segments ; and a cushion i of
indiarubber or other suitable resilient material, arranged and operating sub-
stantially as described with reference to the drawings.
Fourth. In motor-car and other wheels the means for movably attaching the
segments to the wheel substantially as described with reference to Figures 4,
6 and 7 of the drawings.
Fifth. In motor-car and other wheels the means for movably attaching the
segments to the wheel substantially as described with reference to Figure 9
of the drawings.
Sixth. In motor-car and other wheels the means for movably attaching the
segments to the wheel, substantially as described with reference to Figures 10
and 11 of the drawings.
Seventh. In motor-car and other wheels the means for movably attaching the
trough-like segments ; to the wheel, which consist in bending or springing the
sides of such segments open, placing them in position, and then bending or
closing them into their normal shape, substantially as described with reference to
Figure 5 of the drawings.
Eighth. In motor-car and other wheels the means for preserving the relative
positions of the segments j round the circumference of the wheel, substantially
as described with reference to Figures 10, 11, 12 and 13 of the drawings.
