Year: 1879

page_text: LETTERS PATENT to George Dyson Owen and Robert Dyson, of the Firm of
Owen & Dyson, of the Rother Iron Works, The Ickles, Rotherham, in the
County of York, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE
OF RAILWAY AND OTHER WHEELS."
Sealed the 12th August 1879, and dated the 15th February 1879,
..
PROVISIONAL SPECIFICATION left by the said George Dyson Owen and
Robert Dyson at the Office of the Commissioners of Patents on the 15th
February 1879.
GEORGE DYSON OWEN and ROBERT DYSON, of the Firm of Owen & Dyson, of
the Rother Iron Works, The Ickles, Rotherham, in the County of York. "IMPROVE-
MENTS IN THE MANUFACTURE OF RAILWAY AND OTHER WHEELS."
This Invention has reference to the manufacture of railway, tramway, and other
similar wheels.
In making spoke wheels for railways and tramways according to this Invention,
we take spokes preferably tapering in thickness from the centre of the width, with
beads rolled or forged on as usual, and having bent them into the required shape we
place a sufficient number in a belt or ring, and placing them in a furnace or fire the
heads of the spokes are heated to a welding heat. The nave is formed from one
piece of plain iron, which is also heated to a welding heat, placed with the spokes in
dies securely held together, and being operated on by a sufficient force, the piece of
iron is driven into the space which forms the nave, and is welded to the ends of the
spokes.
•
Another plan we adopt is to take spokes with perfectly plain ends and bend them
in the usual manner, and having placed a sufficient number in a belt or ring, with
a plate on the under side, or other contrivance to facilitate carrying the spokes, we
heat the spoke ends to a welding heat and proceed as before.
Wheels with single spokes we proceed with in the same manner, making the
nave from one piece of plain iron, and the spoke ends being made either plain or
with heads,

page_text: In disc wheels the nave is also formed from one solid piece of plain iron heated
to a welding heat. The plate which forms the disc may be heated to a welding
heat, so as to be welded to the nave, or it may be left cold, so that the nave embraces
it firmly. The plate and piece of iron are placed in dies, and operated on as in
spoke wheels.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said George Dyson Owen and Robert Dyson in the Great Seal Patent
Office on the 15th August 1879.
GEORGE DYSON OWEN and ROBERT DYSON, of the Firm of Owen & Dyson, of
the Rother Iron Works, The Ickles, Rotherham, in the County of York, "IMPROVE-
MENTS IN THE MANUFACTURE OF RAILWAY AND OTHER WHEELS."
This Invention has reference to the manufacture of railway, tramway, and other
similar wheels.
In making spoke wheels for railways and tramways according to this Invention,
we take spokes preferably tapering in thickness from the centre of the width, with
heads rolled or forged on as usual, as shown in Figures 1 and 2 of the annexed
Drawings, and having bent them into the required shape A, A, Figure 4, we place
a sufficient number in a belt or ring B, Figure 4, and placing them in a furnace or
fire, the heads of the spokes are heated to a welding heat.
The nave is formed from one piece of plain iron Ď, Figure 6, which is also heated
to a welding heat, placed with the spokes in dies securely held together, and being
operated on by a sufficient force the piece of iron D is driven into the space which
forms the nave, and is welded to the ends of the spokes.
Another plan we adopt is to take spokes with perfectly plain ends (Figure 3), and
bend them in the usual manner, and having placed a sufficient number (E, E,
Figure 5) in a belt or ring, with a plate G (Figure 5) on the underside, or other
contrivance; to facilitate carrying the spokes we heat the spoke ends to a welding
heat and proceed as before.
Figures 9 and 10 show front view and section of wheel after having been made
by either of the foregoing plans.
Wheels with single spokes we proceed with in the same manner, making the nave
from one piece of plain iron, and the spoke ends being made either plain, Figure 12,
or with heads, Figure 11.
Figures 13 and 14 show the completed wheel made on either of these systems.
In disc wheels we proceed in the same manner, the nave being formed from one
piece of plain iron, which is heated to a welding heat; the part of the disc at the
nave is also heated, and both are welded together in dies as before.
Figure 15 shows a disc wheel when welded on this plan, and having a tire placed
upon it to complete the wheel. -

page_text: Figures 18 and 19 show a disc wheel made upon another plan; the disc in this
case is not heated. The plain piece of iron only is heated to a welding heat, and
both are placed in dies, and the piece of plain iron is forced into the die, so that the
disc is embraced and held firmly.
Having now described the nature of our said Invention, and in what manner the
same is to be performed, we declare that we claim,―
First. The production of the naves of wrought iron spoked railway wheels from
one piece of plain iron, as described and shown in the Drawings.
Secondly. The production_of_the_naves of wrought-iron-disc-railway-wheels-from-
one piece of plain iron, as described and shown in the Drawings, the discs either
being heated or not heated.
In witness whereof, we, the said George Dyson Owen and Robert Dyson, have
hereunto set our hands and seals, this Twelfth day of August, One thousand
eight hundred and seventy nine.
