I, GEORGE LAMB SCOTT, of 18, Nelson Street, Manchester, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:
My said invention relates to improvements in wheels for vehicles and the object
of my invention to construct a wheel so as to cut off vibration, shock and jar
and destroy the continuity of such vibration.
In constructing a wheel in accordance with my invention I dispense with the
usual wooden felloe and I provide a metallic rim of trough section which carries
a rubber tyre preferably rounded on its outer periphery. The rubber tyre pro-

improved wheel rolls upon the road the projecting rubber tyre comes first into
noiseless contact with the ground and under the weight of the vehicle the rubber
collapses and thus acts as a cushion to gradually and noiselessly bring the metallic
tyre into contact with the ground.
In the manufacture of my improved wheel the spokes are provided at their
outer ends with suitable metallic sockets. These sockets are cast with holes, or
are bored out, for the reception of the spokes, and are also formed with extended
outer ends to form a bearing for the rim.
Upon the extended bearing surfaces of the sockets I place a layer of rubber or
other resilient or sound deadening material and I then shrink or suitably com-
press round the spoke sockets the metallic rim of trough section, the strength
of which will vary according to the class of vehicle for which the wheel is
intended.
The metallic rim is then secured to the extended surface of the sockets by
means of bolts rivets or other suitable fastenings. The metallic rim is provided
with a rubber tyre which may be rounded on its outer periphery and which

securely fixed in position upon the spoke sockets I cut the metallic rim trans-
versely at the centre of each spoke, or alternate spoke or at any spoke, so as to
destroy the continuity of the rim.
The rubber tyre is also cut into segments of any desired length.
The metallic rim is entirely cut through to the spoke sockets and bolted in
segments to the sockets. Thus the jar and vibration are cut off and cannot be
communicated to the neighbouring segments. The rubber tyre may be in seg-
ments of the same length as the segments of the rim and the joints of each
segment may be in the same line or they may break joint. I may however only
partially cut through the thickness of the rim so that the base of rim is con-
tinuous, the partial cuts being placed either over each socket or alternate sockets
or in any portion of the rim. The spokes are preferably oval in cross section
and the ends may pass partially, or it might be completely through the sockets
and bed against the underside of the rubber placed upon the extended socket
ends.

page_text: I do not confine myself to the arrangement of rim as described as instead of
cutting the metallic rim, and rubber tyre, the rim and tyre may be left uncut
and continuous so long as the rubber tyre projects slightly beyond the metallic
rim and thus acts as a cushion to collapse, and gradually bring the metallic rim
noiselessly and without shock to bear upon the ground.
A wheel rim such as I have described, besides the advantage of being noiseless,
is of great strength and possesses wear resisting properties to a high degree.
Any suitable hub may be used in conjunction with my improved rim although
I prefer to use a hub such as is described in the Specification of my Letters
Patent No. 27617 of 1896.
Improvements in Wheels for Vehicles,
I, GEORGE LAMB SCOTT, of 18, Nelson Street, Manchester, in the County of
Lancaster, 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 and accompanying drawings:-
My said invention relates to improvements in wheels for vehicles and the object
of my invention is to construct a wheel so as to cut off vibration, shock and jar
and destroy the continuity of such vibration.
In constructing a wheel in accordance with my invention the usual wooden
felloe is dispensed with and I provide a metallic rim of trough section which
carries a rubber tyre which may, or may not, be rounded on its outer periphery.
The rubber tyre projects slightly beyond the extenal periphery of the metallic
rim. When the improved wheel rolls upon the road the projecting rubber tyre
comes first into noiseless contact with the ground, and, under the weight of the
vehicle, the rubber collapses and thus acts as a cushion to deaden the impact and
gradually and noiselessly bring the metallic tyre into contact with the ground.
The accompanying sheet of drawings clearly illustrates my invention.
Fig. 1 is a side elevation of a wheel constructed in accordance with my
invention.
Fig. 2 is an edge view of same.
Fig. 3 is a cross sectional view of the rim and tyre on an enlarged scale.
Fig. 4 is a portion of wheel rim showing a modified form of my invention.
In manufacturing my improved wheel I use a suitable form of hub and pro-
vide the spokes a at their outer ends with metallic sockets b.
These sockets are cast with holes, or are bored out, for the reception of the
spokes a, and are also formed with extended outer ends to provide a bearing for
the rim.
Upon the extended bearing surfaces of the sockets I place a layer of rubber c
or other resilient or sound deadening material and I then shrink or suitably
compress round the spoke sockets the metallic rim d of undercut trough section,
the strength of which will vary according to the class of vehicle for which the
wheel is intended.
The metallic rim is then secured to the extended surface of the sockets by means
of bolts, rivets or other suitable fastenings e. The metallic rim is provided with
a rubber tyre f which may or may not be rounded on its outer periphery and which

page_text: projects slightly beyond the periphery of the metallic rim as shown more clearly
in the cross sectional view Fig. 3. When the rim d is securely fixed in position
upon the spoke sockets I may cut the metallic rim transversely at the centre of
each spoke, as shown in the upper half of Fig. 1, or alternate spoke as shown
in the lower half of Fig. 1, or at any spoke, so as to destroy the continuity of
the rim.
The rubber tyre f is also cut into segments of any desired length.
The metallic rim is entirely cut through to the spoke sockets and bolted in
segments to the sockets as shown in the upper half of Fig. 1. Thus the jar
and vibration are cut off and cannot be communicated to the neighbouring seg-
ments. The rubber tyre f may be in segments of the same length as the segments
of the rim.
The joints of each segment may be in the same line as the segments of the
rim as shown in the lower portion of Fig. 1 or they may break joint as illus-
trated in the upper part of Fig. 1. I may however only partially cut through
the thickness of rim d so that the base of the rim is continuous, the partial cuts
being placed either over each socket or alternate sockets or in any portion of
the rim. The partial cutting of the rim d is shown in the lower half of Fig. 1.
The spokes a are preferably oval in cross section and the ends may pass partially,
or it might be, completely through the sockets 6 and bed against the underside
of the rubber e placed upon the extended socket ends.
This alternative method is indicated in dotted lines in Fig. 3.
I do not confine myself to the arrangement of rim as described as instead of
cutting the metallic rim d and rubber tyre f the rim and tyre may be left
uncut and continuous as shown in Fig. 4, so long as the rubber tyre f projects
slightly beyond the nietallic rim d and thus acts as a cushion to collapse, and
gradually bring the metallic rim noiselessly and without shock to bear upon
the ground.
A wheel rim such as I have described, besides the advantage of being noiseless,
is of great strength and possesses wear resisting properties to a high degree.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is: -
1) In wheels for vehicles a metallic rim of trough section secured to spoke
sockets, said rim having its continuity interrupted by transverse cuts, and pro-
vided with an interrupted rubber tyre projecting slightly beyond the periphery
of the rim so as to first come into contact with the ground and act as a cushion
to deaden the impact and gradually and noiselessly bring the metallic tyre into
contact with the road substantially as described.
2) In wheels for vehicles a metallic rim of trough section secured to spoke
sockets, the said rim being continuous and provided with a continuous rubber
tyre projecting slightly beyond the periphery of the rim so as to first come into
contact with the ground and act as a cushion to deaden the impact and gradually
and noiselessly. bring the metallic tyre into contact with the road substantially
as described.
