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 to be as
follows:-
My said invention relates to wheels for vehicles of the type described in the
Specification of Letters Patent No. 24331 of 1898.
The object of my invention principally is to construct a wheel so as to destroy
vibration shock and jar.
In carrying my invention into effect I employ the usual or ordinary wheel
with wooden felloe or rim and around the outer periphery of the felloe I place
a layer or thickness of rubber or other sound deadening or resilient material.
Upon this layer of rubber I shrink, compress, bolt or otherwise secure a metallic
rim of trough or channel section, which metallic rim carries a tyre of rubber
or other resilient material.
The rubber tyre is preferably slightly rounded on its outer periphery and
projects to a slight extent beyond the metallic rim. When the wheel rolls upon
the road the weight brought to bear upon it causes the rubber tyre, which first
comes into contact with the ground, to collapse and thus bring the metallic rim
noiselessly and without shock or jar to the ground. The wheel thus combines
the noiselessness of a rubber tyred wheel with the wear resisting properties of a
metallic tyred wheel.
The metallic rim may be continuous or cut in segments or the rim may be
partially cut through in any convenient number of places with the object of
cutting off vibration or jar and destroying its continuity. The rubber tyre may
also be continuous or in sections.
The rubber insertion between the wood felloe or wood rim and the metallic
rim may if desired be dispensed with.

page_text: what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement and accompanying drawings:-
My said invention relates to wheels for vehicles of the type described in the
Specification of Letters Patent No. 24331 of 1898.
The object of my invention principally is to construct a wheel so as to destroy
vibration, shock and jar and to apply the principle disclosed in my said former
patent to wheels with wooden felloes of ordinary construction.
The accompanying sheet of drawings clearly illustrates my invention.
In the said drawings.
Fig. 1 shows in cross section a wheel tyre constructed in accordance with my
invention.
Fig. 2 is a portion of the wheel tyre in plan view.
Fig. 3 is a front view of a portion of the improved wheel tyre.
In carrying my invention into effect I employ the usual or ordinary wheel
with wooden felloe or rim a and around the outer periphery of the felloe I place
a layer or thickness of rubber b or other sound deadening or resilient material.
Upon this layer of rubber I shrink, compress, bolt or otherwise secure a steel or
other metallic rim c of trough or channel section, which metallic rim carries a
tyre d of rubber or other resilient material.
The rubber tyre is preferably slightly rounded on its outer periphery and
projects to a slight extent beyond the metallic rim c. When the wheel rolls
upon the road the weight brought to bear upon it causes the rubber tyre d which
first comes into contact with the ground, to collapse and thus bring the metallic
rim c noiselessly and without shock or jar to the ground the rubber tyre & pro-
jecting sufficiently only to effect this object.
The wheel thus combines the noiselessness of a rubber tyred wheel with
the wear resisting properties of a metallic tyred wheel.
The wheel runs both on the rubber tyre and metallic rim which thus mutually
protect each other, the steel rim protecting the rubber whilst the rubber by its
cushioning action destroys the destructive impact of the metal rim upon the
road.
For
In wheels for a light vehicle such as a hansom cab I find that a projection of
about three eights of an inch of rubber beyond the metal tyre is suitable.
a heavier vehicle such as an omnibus the projection of rubber would exceed
this, the projection of rubber found suitable being nine sixteenths of an inch.
I do not confine myself however to these proportions as they would necessarily
vary according to the resiliency of the rubber employed and the weight of the
vehicle.
The metallic rim c and rubber tyre may be continuous as shown in Fig. 3
or the rubber tyre d may be cut in segments, and the rim be partially cut
through transversely in any convenient number of places with the object of
cutting off vibration or jar and destroying its continuity, as shown in Fig. 4.
The rubber tyre d is channelled at the edges as shown clearly in the
sectional view Fig. 1, so that the edges of the rubber are prevented from being
cut by road metal, loose stones or the like, or by the metal rim when it gets
burred over by continual impact with the road.
The rubber insertion between the wood felloe or wood rim and the metallic rim
may if desired be dispensed with.
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:
In wheels for vehicles the combination with the wooden felloe a of a metallic
rim of trough section, continuous or partially cut through transversely with
or without the rubber insertion b, and of a rubber tyre d continuous or in seg-
ments projecting sufficiently above the metallic rim so as to collapse on contact

without shock and jar upon the ground substantially as described and illustrated.
