PROVISIONAL SPECIFICATION left by the said Walter Eyre at the Office
of the Commissioners of Patents on the 20th February 1883.
WALTER EYRE of 167 Ellesmere Road, Sheffield, in the County of York, Manager
"IMPROVEMENTS IN THE CONSTRUCTION OF RAILWAY AND OTHER WHEELS AND IN
THE MODE OF FIXING SUCH WHEELS ON THEIR AXLES
C
My Invention has for its object the construction of wheels from a plate of
wrought steel or iron, thereby rendering them more durable and less liable to
break than when cast as usual; also an improved mode of fixing such wheels upon
their axles.
In order to carry out my improved method I take a piece of iron or steel plate
of such size as may be required and place it either while hot or cold between tools
in a steam hammer, bydraulic press or other suitable machine, and press it into the
required form suitable for a wheel or the centre of a wheel upon which may be
fixed a tyre. The forms of such wrought plates may be varied according to the
form of wheel required, and they may be used as central portions of wheels either
singly or in pairs fastened together with rivets or bolts with a tyro fixed over
them or with a strengthening plate riveted or bolted to the flange of the pressed
or hammered plate.
When the wheel is brought into the required form, I fasten it to the axle in the
manner hereinafter described.
The axle is turned or forged to the shape of a bar having two collars near each
end; holes are drilled through these collars and the wheel or central part thereof
has corresponding holes drilled in it. The said collar and central part of the wheel
are then brought together and fastened by rivets or bolts. These wheels can be
made for either inside or outside, bearings or be made to revolve upon the axle by
fitting a bush to the centre of the wheel.

My Invention has for its object the construction of wheels from a plate of
wrought steel or iron thereby rendering them more durable and less liable to break
than when cast as usual, also an improved mode of fixing such wheels upon their
axles
In order to carry out my improved method I take a piece of iron or steel plate
of such size as may be required and place it either while hot or cold between tools
in a steam hammer hydraulic press or other suitable machine and press it into the
required form suitable for a wheel or the centre of a wheel upon which may be
fixed a tyre. The forms of such wrought plates may be varied according to the 1
form of wheel required and they may be used as central portions of wheels either
singly or in pairs fastened together with rivets or bolts with a tyre fixed over
them or with a strengthening plate rivetted or bolted to the flange of the pressed
or hammered plate.
When the wheel is brought into the required form I fasten it to the axle in the
manner hereinafter described.
The axle is turned or forged to the shape of a bar having two collars near each
end; holes are drilled through these collars and the wheel or central part thereof
has corresponding holes drilled in it. The said collar and central part of the wheel
are then brought together and fastened by rivets or bolts. These wheels can be
made for either inside or outside bearings or be made to revolve upon the axle by
fitting a bush to the centre of the wheel.
Having thus stated the nature of the said invention I will proceed to describe
more particularly in what manner the same is to be performed by the aid of the
accompanying drawings in which are represented different forms of wheels
constructed in the manner above referred to.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a piece of iron or steel plate which having been placed in
either a hot or a cold state between suitable tools in a steam hammer hydraulic
press or other machine has been forged or pressed into the form required, Fig. 2
represents another form of wheel or centre of a wheel upon which may be fixed
a tyre. Fig 3 shews two centre pieces fastened together with bolts or rivets and
adapted to have the tyre fixed over them-At Fig. 4 is shewn an axle forged or
turned into the form required in order that the wheel or centre of a wheel may be
fastened to it for which purpose holes are drilled through the collars a a of the
axle and corresponding holes are formed in the wheel or centre piece thereof and
the parts are brought together and fastened with rivets or bolts as shown in
Figures 7 and 8.
These wheels and axles can be made for either inside or outside bearings. Or
the wheel may be made to revolve upon the axle by fitting a bush or centre piece b
to the centre of the wheel as shewn in Figures 5 and 6. The wheel may be fitted
with a strengthening plate c as shown in Fig: 6.
If the bush b were placed as in Fig: 5 and applied to such form of wheel the
wear being unequal would have a tendency to make the hole in the bush larger at
1

page_text: one end than at the other end. In order to obviate this tendency it is preferable
to use a wheel of the form shewn in Fig: 8 in which the web of the wheel being
thrown centrally over the tread will cause the wear of the bush to be equal
throughout.
Having thus described the nature of the said Invention and in what manner the
same is to be performed I hereby declare that what I claim as of the said
Invention is
First: The construction of wheels from plates of wrought steel or iron substan-
tially in the manner described instead of casting them as usual.
And Secondly-The fixing of such wheels on their axles substantially in the
manner described.
In witness whereof I the said Walter Eyre have hereunto set my hand and seal

and eighty three
