Improvements in Railway and other Wheels and their Mode of
Manufacture.

BARRY TILFOURD STANTON 20 Tivoli Road Crouch End N. Engineer, do hereby
declare the nature of this invention to be as follows: -
Our invention relates more particularly to what are known as Disc Wheels as
generally used upon Railways and Tramways, but it may be applied for making
pulleys and other similar articles.
The improvement consists in the thickening and strengthening of the rim or
periphery of the Wheel Centre and the means we employ to form it readily into
the required shape.
There are various ways of carrying our invention out, but we will proceed to
describe some of them as applied to the manufacture of a Railway Disc Wheel.
In tue manufacture of these wheels we take one or more circular Plates or Discs
of Iron or Steel or other suitable material, the said Discs being approximately of
the same thickness at the edge as at the centre, and in order to form a rim or
periphery on the Disc upon which the Tyre of the Wheel can be fastened, we
place the discs when properly heated, in a powerful hydraulic or other press and
turn over or flange the edge of the Disc through a proper die, and without
removing the Disc from the press and while it is still hot, we press the flanged
edge into another die upon the same or another machine, and set up or form the
flange into the desired shape, making the rim of greater thickness than the
original Disc itself where required.
Instead of flanging the Disc in the way set forth before forming the rim, it
can be flanged by any other suitable method, the flange being subsequently shaped
to form the rim as described.
Or instead of the flange being thickened up and shaped without removing the
Disc from the press, we can remove it and reheat it and form the rim by a subse-
quent operation.
The same press that we use to flange the Disc and shape the rim can be also
employed to give the centre of the Disc any desired form whether corrugated,
dished or plain, or any other suitable pattern, and it can also punch out the centre
hole in the Disc to admit the boss or nave, and all these operations may be done
simultaneously.
In another modification instead of flanging the Disc in the first instance and
thickening up and forming the rim afterwards, we reverse the process and thicken
up the Disc first and then flange and shape it.
In the case of wheels made from a single plate or Disc, the rim would be
formed upon both sides of the plate or disc, and in the case of wheels made from
two plates the rim could be made upon one or both sides of the plate.

page_text: We form the boss or nave in the centre of plates or discs in the usual manner
whether welded, pressed upon the plates while they are cold, or cast, or in the case
of wheels made from two plates we can make the boss in the manner described in
our previous Patents viz. Ños. 14722 of 1891 and No. 18402 of 1895.

BARRY TILFOURD STANTON 20 Tivoli Road, Crouch End, London, N. 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:-
Our invention relates more particularly to what are known as Disc Wheels as
generally used upon Railways and Tramways but it may be used for making
Pulleys and other similar articles.
The improvement consists in the thickening and strengthening of the rim or
periphery of the wheel centre for giving additional support to the Tyre.
There are various ways of carrying our invention out, but we will proceed to
describe some of them as applied to the manufacture of a Railway Disc Wheel,
with reference to the following Drawings.
In the manufacture of these wheels we take one or more circular plates or Dises
of Iron or Steel or other suitable material the said discs being of approximately
uniform thickness all over. In order to form the rim or periphery on the circular
plate or disc upon which the tyre of the wheel is to be fastened, we place the
plate or disc when properly heated in a powerful Hydraulic or other press fitted
with suitable dies & turn over the edge of the plate as shown at "a" Fig. 1 we
then place the plate with the thickened edge in a press provided with suitable
dies and form the thickened flange as shown at "6" Fig. 2.
Instead of thickening the plate or disc in the way described before forming the
flange it can be thickened by any other suitable method the flange being subse-
quently shaped to form the thickened rim as described.
The same press that we use to flange the disc can also be employed to give the
centre of the disc any desired form either plain ribbed dished or corrugated or
any other suitable pattern & it can also punch out or remove the centre hole
required in the disc to admit of the fixing of the boss or nave & all these opera-
tions may be done simultaneously.
In another modification we first flange the disc as shewn at c Fig. 3 and then
thicken up the flange in a suitable die as shewn at b. Fig. 2.
In the case of wheels made with a single plate or disc the rim would be formed
on both sides of the plate as shewn at e Fig. 4 and in the case of wheels made
with two plates the rim could be made upon one side only of the plates as shewn
at "Fig. 5 or upon both sides of the plates as shewn at "9" Fig. 6.
We form the box or nave in the centre of the plates or discs in the usual
manner whether welded, pressed upon the plates while they are cold, or cast, or

page_text: in the case of wheels made with two plates we can make the boss in the manner
described in our previous Patents viz. No. 14722 of 1891 and No. 18402 of 1895
as shewn at d Fig. 5.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. A wheel centre made from two (or more) plates or discs with thickened rims
for the purpose of giving additional support to the tyre substantially as described.
2. A Railway or Tramway Disc Wheel made from two plates having thickened
rims in combination with a boss or nave formed in the centre of the said plates,
by the employment of a ring or lining as shewn in Fig. 5 & 6 and as fully
described in our Patents Nos. 14722 of 1891 and 18402 of 1895.
