the County of Durham Steel Founders, "IMPROVEMENTS IN THE METHOD OF AND
APPARATUS FOR CONVERTING CAST IRON INTO, STEEL, OR STEELY IRON
•
"
The object of our Invention is to convert Iron castings into steel or steely iron
castings, by a simple method and inexpensive apparatus without using ore, ashes or
any other materials to mix with the castings whilst they are being converted.
For this purpose an oven is constructed containing a chamber of a number of
chambers, which shall be so arranged, that the flame can only pass around the
outside of the said chamber or chambers.
We place the castings which are made of cast iron into the chambers the ends of
which are afterwards sealed up.
The furnace under the oven is then ignited, and the castings kept at a certain
heat for a suitable length of time whereby they are converted into steel or "steely
iron."

JOSEPH BOND and HENRY JOSHUA WHITELEY of Tow Law near Darlington, in
the County of Durhain Steel Founders "IMPROVEMENTS IN THE METHOD OF AND
APPARATUS FOR CONVERTING CAST IRON INTO STEEL OR STEELY IRON"
The object of our Invention is to convert cast iron castings into steel or "steely
iron" castings, by a simple method and inexpensive apparatus, without using ore,
ashes or any other materials to mix with the castings whilst they are being
converted. For this purpose an oven is constructed, containing a chamber or a
number of chambers, which shall be so arranged that the flame can only pass
around the outside of the said chamber or chambers.
In order that our Invention may be better understood we herein give reference
to the accompanying sheet of Drawings wherein Fig 1 is a longitudinal section of
the form and construction of apparatus we employ. Fig. 2 is end elevation, Fig 3
plan and Fig 4 cross section of same. A is an oven or furnace which may bo
constructed in several forms for receiving a series of tubes or chambers B with
Covers C thereon.
"
Openings D and flues E' for distributing the flames and heated gases are
arranged as thought most convenient, and F is a chimney for carrying away the
smoke and spent gases. The castings to be converted into steel or "steely iron
are placed into the tubes B after which the upper ends are sealed. by covers: C.
The fire is then ignited, the heat of which is regulated, so as to keep the tubes at a
suitable temperature for a certain length of time, by which means the castings are
converted into steel or steely iron. G are similar tubes or chambers to B, but of
larger diameter for the purpose of holding larger castings than what could be
placed into the chambers B.
It will be observed, that we have not stated what temperature it is necessary to
keep the oven, nor the length of time the castings are to be kept in the chamber B,
because those are matters which will vary according to the size of castings under
operation and to the varying construction of furnace, and arrangement of flues.
Having now shewn and described our Invention and the manner in which the
same is to be performed and carried into practice, we would have it. understood
that we do not confine ourselves to the exact details herein illustrated and
explained as they may be varied without departing from the main features
thereof; for instance the size and form of oven may be varied, the same may also
be said of the tubes or chambers B, therefore what we claim is-
The method of and apparatus for converting cast iron castings into steel or
"steely iron "in manner substantially as herein shewn and described.
In witness whereof we the said Joseph Bond and Henry Joshun Whiteley
have hereunto set our hands and seals this third day of April in the year
of our Lord, one thousand, eight hundred and eighty three.
