PROVISIONAL SPECIFICATION.
Improvements in the Construction of Railway and other Wheels.
I, FRANS HJALMAR RUNDQUIST WANNER, of Liljeholmen Stockholm, Sweden,
Works Manager do hereby declare the nature of this invention to be as
follows:-
:
My invention relates to the construction of railway and other wheels of iron or
steel and especially to the intermediate part of the wheel viz. the part which
unites the hub and the rim, and whereby the wheel obtains great strength and a
certain amount of elasticity.
This intermediate part of the wheel being constructed with two sets of spokes
of T or other suitable section placed with the base line of section at right angles
to the centre line of axle in two conical dish shaped or otherwise formed surfaces,
have one set or half number of spokes in the one surface and the other set of spokes
every alternate one in the other surface. These spokes are united or continued
into each other by circular lines which do not cut the periphery of the nave but
rather run tangentially thereto, the body of all the spokes starting from the middle
height of the rim, butevery alternate one of them proceeding towards a point
at or near one end of the nave and the other alternate ones proceeding to a point
at or near the opposite end of the nave. Or in another form the one set of spokes
starts from a point a little to one side of the middle height of the rim and the
other set or alternate spokes from a point a little to the other side of the middle
height of the rim. These two sets of spokes with the apertures between them form
the intermediate part of the wheel.

COMPLETE SPECIFICATION.
Improvements in the Construction of Railway and other Wheels.
I, FRANS HJALMAR RUNDQUIST WANNER of Liljeholmen Stockholm, Sweden,
Works Manager 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 :—
My invention relates to the construction of railway and other wheels of iron and
steel for the purpose of ensuring great strength or non-liability to fracture and a
certain amount of elasticity in the parts between the nave and the rim.
The intermediate part of the wheel being constructed with two sets of spokes
of Tor other suitable section placed with the base line of section at right angles
to the centre line of axle in two conical dish shaped or otherwise formed surfaces
have one set or half number in the one surface and the other set of spokes every
alternate one, in the other surface, and these spokes are united or continued into
each other by circular lines or curves which do not cut the periphery of the nave
but rather run tangentially thereto presenting no sharp corners conducive to
fracture, but large curve lines for the purpose stated.
In another form the two sets
of spokes are separate.
Figure 1 of the accompanying drawings is a perspective view of a railway
carriage wheel of my invention.
Figure 2 a section of rim and tyre on line a ₺ Figure 1.

page_text: Figure 3 a longitudinal section shewing the two sets of spokes and Figure 4 a
cross section through both.
Between the rim B and the nave A there are two sets of spokes namely C¹ and C
which start alternately from a rib C on the inner side of the rim B and proceed,
every alternate one C¹ in a more or less, slanting, straight or curved direction to a
point at or near one end of the nave A, and the other alternate ones C" proceeding
to a point at or near the opposite end of the nave. It will be observed that the
spokes in each set at the nave united by large easy curves, and that the spokes of
one set are similarly united with the spokes in the other set, thus great strength is
combined with some elasticity.
Figure 5 is a perspective view and Figure 6 a longitudinal section of another
form of wheel wherein one set of spokes C starts from a point a little to one side.
of the middle of height of rim B, and the other set of alternately placed spokes C¹¹
from a point a little to the other side of the middle of height of rim, the two sets
being separate.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
Firstly. In wheels of the character named uniting the nave and the rim by two
sets of spokes which are united to each other by large or easy curves substantially
as described, whereby great strength is obtained together with a certain amount of
elasticity.
Secondly. The improved construction of wheel described with reference to
Figures 1 to 4.
Thirdly. The improved construction of wheel described with reference to
Figures 5 and 6.
