PROVISIONAL SPECIFICATION.
Improvements in Wheels for Common Road Vehicles.
I GODFREY JOBSON of Grange Court, Ealing in the County of Middlesex,
Ironfounder do hereby declare the nature of this invention to be as follows:
--
The object of the invention is to so construct wheels of common road vehicles as
to prevent the conveyance of the effects of concussion from the parts of the wheel
in contact with the road to the other parts of the wheel and vehicle and to prolong
the effective life of the wheel by obviating destructive strains.
In carrying out my invention I employ an axis which may be of substantially
usual construction-having flanged collars coned ends, pinned collars and pins.
Upon this cone end (referring to one end of such an axle) is mounted a
correspondingly bored steel bush, having inwardly of its external diameter an
annular flange, next a larger diameter and two lesser diameters, each extending one
beyond the other towards the outer face of the wheel. On the larger diameter is
mounted a cast iron, or other suitable annular part shaped somewhat like a crowned
wheel the spaces between the teeth, so to speak, each forming three sides of a
socket for a spoke which may be of tubular metal. On the next adjoining diameter
is mounted a tapered cone annular part, upon which tapered ends of the spokes
butt and are pressed outwards in the tightening up of the parts. On the next
diameter is mounted a loose collar which when clamped up against the open sides of
the spoke sockets closes the spokes thereinto and forces their ends up the inclined
faces of tapered cone annulus. Against this loose collar presses a collar or circular
plate formed with a screw thread which engages a thread formed on this outward
and smallest diameter of the steel bushing, and behind this again is screwed up the
cap of the wheel.
Each spoke at its outer end is formed with a cup shaped or recessed end, which
receives an india rubber or elastic pad and this pad rests in another cup shaped
opening or other recess in the rim of the wheel, on which rim may be mounted a
metallic tyre.
Or according to a modification the tyres may each be formed with a cupped or
recessed end to receive one side of an india rubber or like pad, the other side of
which is bedded in a like recess in an intermediate part or knuckle which again at
its outer side receives another india rubber or elastic pad into its recessed extremity
and this second elastic pad is partly received into a like cupped recess in the felloe
or rim of the wheel, on which may be mounted an ordinary tyre.
By these means an easy motion is secured to the inward parts of the wheel and
5 to the vehicle, a certain but well controlled amount of elastic play is allowed
to the tyre parts of the wheel and wrenching strains on the hub are avoided.
I do not confine myself to the form of axle construction or to the parts adjacent
thereto.

I GODFREY JOBSON, of Grange Court, Ealing, in the County of Middlesex,
Ironfounder, 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 :-
The object of the invention is to so construct wheels of common road vehicles as
to prevent the conveyance of the effects of concussion from the parts of the wheel
in contact with the road to the other parts of the wheel and vehicle and to prolong
the effective life of the wheel by obviating destructive strains.
In carrying out my invention I employ an axis which may be of substantially
usual construction having flanged collars, coned ends, pinned collars and pins.
Upon this coned end (referring to one end of such an axle) is mounted a
correspondingly bored steel bush, having inwardly of its external diameter an
annular flange, next a larger diameter and two lesser diameters, each extending one
beyond the other towards the outer face of the wheel.
to
On the larger diameter is mounted a cast iron, or other suitable annular part
shaped somewhat like a crown wheel the spaces between the teeth, so
speak, each forming three sides of a socket for a spoke which may be of tubular
metal.
.
On the next adjoining diameter is mounted a tapered cone annular part; upon
which tapered ends of the spokes butt and are pressed outwards in the tightening
up of the parts.
On the next diameter is mounted a loose collar which when clamped up against
the open sides of the spoke sockets closes the spokes thereinto and forces their
ends up the inclined faces of tapered cone annulus.
Against this loose collar presses a collar or circular plate forined with a screw
thread which engages a thread formed on this outward and smallest diameter of
the steel bushing, and behind this again is screwed up the cap of the wheel.
Each spoke at its outer end is formed with a cupped or recessed end which
end receives an india-rubber or equivalent elastic pad and each such pad rests in
another cupped or recessed part formed on or in the rim of the wheel and on this
rim may be mounted a metallic or other tyre. Within or more or less adjacent
to the hub of the wheel each spoke is formed with a pair of cupped or recessed
parts interposed between which is another india rubber, pneumatic or equivalent
elastic pad, thereby an intermediate part or knuckle ended joint is formed between
the hub end and the rim end of each spoke.
The spokes are formed hollow and fixed securely in the hub section of each of
the spokes is the butt end of a tapered stiffener rod or internal spoke which passes
down through the hollow intermediate part spoke into the rim portion so as to
control the lateral flexure of the spokes, but allowing a limited play in that direction
as well as a radial play of the part spokes as the rubber pads are compressed
between hub and rim.
To avoid concussive contact between the taper end of the stiffener and
the rim recess in which that end lies either may be covered or lined as with
leather.

This axle box has a solid collar or head h' to it.
Next to this head is mounted on the external diameter of axle box a cast iron or
other suitable annular part shaped somewhat like a crown wheel i.
Next to this comes the expander conej which has as many sides as there are
spokes. The taper ends of the spokes d butt against the cone and are pressed
outwards in the tightening up of the parts.

the outer face of the rubber f; it is brazed or otherwise fastened into the rim a and
also forms thereby a stay, or connection between the two sides of the rim to
stiffen it.
It also has a rectangular space in its centre which allows the inner spoke d free
play vertically through there being more or less play allowed in the vertical plane
of the wheel, but it is confined laterally much more closely so as to prevent the rim
of wheel being displaced by undue side strains.
I do not confine myself to the employment of two rubber pads to each spoke as
such number with their corresponding cup recesses may be varied.
By these means an easy motion is secured to the inward parts of the wheel and
to the vehicle, a certain but well controlled amount of elastic play is allowed to
the spoke parts relatively to the rim or felloe parts of the wheel and wrenching
strains on hub are avoided.
In constructing wheels according to my invention I do not confine myself to the
45 form of axle construction or to the parts adjacent thereto.
