PROVISIONAL SPECIFICATION.
Improvements in Wheels.
I, JAMES CLEMINSON of Dashwood House, 9 New Broad Street, in the City of
London & County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to a new & improved method of constructing, railway,
tramway, or other wheels, whereby great lateral stability combined with elasticity &
direct resistance to torsional strains are obtained.
According to one method the nave which may be either cast or wrought of any
suitable metal, is formed with one or more spokes or radial arms and also with a
groove on each of its sides or faces.
The tyre is rolled with a ridge or rib or ridges or ribs on the inside and bas
a groove formed on each side of the said ridge or rib, recesses are also formed in
this rib or ridge into which the spokes or arms fit.
Discs or plates are provided with a hole through the centre of each & with lips or
flanges formed on their outer and inner sides, these discs or plates are bulged or
formed with one or more depressions which occur between the arms of the nave.
When the wheel is built up the nave is within the tyre, the ends of the spokes or
arms fitting into the recesses formed in the beforementioned inside rib or ridge of
the tyre, and the discs are placed on each side of the nave. The flanges on the
inside of the discs fitting into the grooves in the nave & tyre; the whole being
held together by bolts or rivets passed through the discs at the depressions between
the spokes or arms of the nave, through the discs and nave, and also through the
discs & tyre.
If required the bolts through the depressions in the discs may be omitted, as also
the grooves in the nave or tyre or those in both nave & tyre.
One or both of the flanges on the discs may also be omitted.
COMPLETE SPECIFICATION.
Improvements in Wheels.
I, JAMES. CLEMINSON, of Dashwood House, 9 New Broad Street in the City of
London and County of Middlesex, Civil 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 :-
This invention relates to a new and improved method of constructing railway,
tramway, or other wheels, whereby great lateral stability combined with elasticity and
direct resistance to torsional strains are obtained.
"
The nave
A" which may be either cast or forged of any suitable metal, is formed
with one or more spokes or radial arins "B" and also with a groove on each of its
sides or faces as shown at "C."
The tyre is rolled with a ridge or rib or ridges or ribs "D" on the inside and has
a groove formed on each side of the ridge or rib for the reception of the flanged
edges "J" of the discs as shown at "E."
Recesses are also formed in this ridge or rib into which the spokes or arms "B"
fit, as shewn at G.
The discs or plates "H" are provided with a hole through the centre of each and
with lips or flanges "J" formed on their sides; these discs or plates "H" are bulged

page_text: or formed with one or more depressions "K" which occur between the arms or
spokes "B" of the nave.
When the wheel is built up, the nave "A" is placed within the tyre and the ends
of the spokes or arms
" B" fit into the recesses "G" and the discs "H" are placed
on each side of the nave "A," the flanges "J" fitting into the grooves "E" and "C"
the whole being held together by bolts or rivets passing through the discs at the
depressions between the spokes or arms of the nave, as shown at M and by bolts or
rivets passing through the discs as shown at "L" and "O."
It is evident that the bolts or rivets may if desired be passed through the discs and
nave and through the discs and tyre.
If required the bolts through the depressions in the discs at "M" may be omitted
as also the grooves "C" in the nave, or "E" in tyre or those in both nave and tyre.
One or both of the flanges "J" on the discs may also be omitted if desired.
Fig. 1. is a part elevation.
Fig. 2. shows sections through the bulges in discs on one side, and through dises
between bulges on the other side.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what
I claim is,
1st. In a wheel the combination of the nave and spokes with the discs and tyre
substantially as herein described and shown on the drawings.
2nd. The general arrangement of parts and method of construction as herein
described and shown on the drawings.
