IMPROVEMENTS IN THE CONSTRUCTION OF RAILWAY AND OTHER WHEELS
Year: 1884

page_text: I WALTER EYRE of 167, Ellesmere Road, Sheffield in the County of York
Manager do hereby declare the nature of iny said Invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF RAILWAY AND OTHER WHEELS" to be as follows:-
My invention relates to the construction of wheels for use on railways or for
colliery, tram and other vehicles, and has for its object the production of a forged
weldless wheel in which the boss forms part of the wheel itself and is forged at the
same time with the wheel, as an improvement upon the invention described in the
specification of a patent granted to me and bearing date 20th February 1883
No 937, in which the boss was fastened to the central part of the wheel after the
wheel was forged.
Under my present invention, I take a piece of steel or iron of such size as may
be required and forge-it into the form of a flat disc with a boss on cach side of the
plate, and afterwards form it into the shape required with dies that may be used
either with a hammer or a press.
The said disc may be made of various thicknesses and of an uneven thickness
so that a wheel may be made from it thicker or stronger in one part than another
if required.
By this means the wheel may be either formed complete for use or so as to
constitute the centre part of a wheel on which a tyre is afterwards fixed in the
manner described in the specification above referred to or in any other suitable
manner;

I, WALTER EYRE of 167 Ellesmere Road Sheffield in the County of York
Manager do hereby declare the nature of my said Invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF RAILWAY AND OTHER WHEELS" and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement:-
Mý Invention relates to the construction of wheels for use on railways or for
colliery tram and other vehicles and has for its object the production of a forged
weldless wheel in which the boss forms part of the wheel itself and is forged at the
same time with the wheel as an improvement upon the Invention described in the
Specification of a Patent granted to me and bearing date 20th February 1883
No 937, in which the boss was fastened to the central part of the wheel after the
wheel was forged.
Under my present Invention I take a piece of steel or iron of such size as may
be required and forge it into the form of a flat disc with a boss on each side of the
plate and afterwards form it into the shape required with dies that may be used
either with a hammer or a press.
The said disc may be made of various thicknesses and of an uneven thickness
so that a wheel may be made from it thicker or stronger in one part than another
if required.
By this means the wheel may be either formed complete for use or so as to
constitute the centre part of a wheel on which a tyre is afterwards fixed in the
manner described in the Specification above referred to or in any other suitable
manner.
In order that my Invention may be fully understood I will proceed to describe it
more particularly by the aid of the accompanying drawings in which are repre-
sented the parts of apparatus above referred to.

page_text: The above mentioned forms may either be used as entire wheels as shown in
Fig: 3 or as centres of wheels upon which tyres are fixed as for example in the
manner shown in Fig: 6 the tyre D being fixed upon the central part E.
The dies employed would usually be made in two parts F and G as shewn in
Figures 4 and 5 but they may be composed of more parts if necessary.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is
First: The production of a forged weldless wheel in which the boss forms part
of the wheel itself, by means of suitable swage tools or dies substantially as
described.
And secondly: The production of a forged and weldless centre part of a wheel
and boss by means of suitable swage tools or dies substantially as described.
Dated this seventh day of February 1885.
WALTER EYRE.
