Improvements in Wheels for Velocipedes and other Vehicles.
We, GEORGE WASHINGTON SMILEY of 26 Coventry Street London, in the
County of London, Merchant, and FOREST WILLIAM DUNLAP, of 41 Eccles Road
Clapham 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 :-
Our invention relates to improvements in wheels for velocipedes and other
vehicles and it has for object mainly to overcome or lessen vibration without
weakening the frame, or rendering the machine liable to derangement through
puncture as are machines with ordinary pneumatic tyres.
It consists essentially in supporting the tyre which may be of solid rubber or any
suitable material, provided on its inner surface with a series of projections or studs,
upon auxiliary moveable spokes, which at any convenient distance between the rim
and the centre or axis bear upon a pneumatic or other elastic cushion carried by a
flange extending outwards from the hub, or by a frame attached thereto, such
spokes passing through suitable perforations in the rim which is carried in the
ordinary way by fixed spokes attached to the hub.
In the accompanying sheet of drawings, on which
Figure represents a vertical section of a wheel constructed according to our
invention, and
Figure 2, a transverse section of the same.
A represents the hub, which for convenience of attachment of the parts
subsequently to be described is preferably made in two parts secured together by
B is the rim of felloe
means of the bolt or axis a, or in any suitable manner.
carried by the fixed spokes C, C. D, D, are the auxiliary or movable spokes passing
through the holes E E, in the rim, and furnished at their inner ends with
flanges F F, and at their outer ends with the flanges G, G, formed so as to embrace
the rubber or other tyre H, (the studs or projections fitting in between the
meeting edges of the flanges G) and of a width to work within the rim B; or we
may make the outer flanges in one continuous length. The flanges F, F, are
arranged around the pneumatic or other elastic cushion I, which is carried by the
flange K, K, attached rigidly to the arms L, L, projecting from the hub.
operation the upward pressure upon the tyre H, is communicated through the
auxiliary moveable spokes D, to the pneumatic or elastic cushion I.
In
Our pneumatic or elastic cushion may be provided with a number of projections i,
on its outer surface corresponding in number and width to the openings between the
inner flanges F upon the auxiliary spokes D, for the purpose of securing the same
in position. The flange K, K, may be made either in one or in several sections,
and the flange K, so constructed as to serve as a guide for the cushion I, as well as
for the flanges F, F; or the flanges F, F, may serve as a guide for the cushion and
the flange or flanges K, K.
Instead of the arms L, L, we may use a continuous solid or perforated disc or we
may place the cushion at any convenient distance from the centre or axis, and
support it from the fixed spokes, but for the sake of the elasticity which arises from
increased length, we prefer to bring it as near the rim as is possible without exposing
it to the risk of puncture from obstacles on the road.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-

.
linda another whooled serriace or vehicle, the use of a series of

page_text: movable spokes auxiliary to the spokes which support the rim, and having flanges
at either end substantially as described.
2. In wheels for velocipedes or other wheeled carriages or vehicles, the use of a
rim or felloe having perforations to permit the passage of movable spokes
substantially as described.
3. A pneumatic or other elastic cushion or series of cushions, arranged at any
convenient distance around the axis of a wheel, in combination with movable
auxiliary spokes substantially as described.
4. A pneumatic or other elastic cushion arranged at any suitable distance around
the axis of a wheel, and provided with a series of projections on its outer surface
substantially as and for the purpose described and shewn on accompanying
drawings.
5. In wheels for velocipedes or other wheeled carriages or vehicles, the use of an
india rubber tyre having a series of projections or studs upon its inner face
substantially as and for the purpose described and shewn on accompanying
drawing.
6 Wheels for velocipedes or other wheeled carriages or vehicles, constructed
and arranged substantially as described and illustrated in Figures, 1 and 2, of the
accompanying drawing.
Dated this Nineteenth day of June 1893.
