Scotland Limited of Glasgow, in the County of Lanark North Britain for
an Invention of "IMPROVEMENTS IN APPARATUS FOR CONVEYING STEEL INGOTS
IN A HEATED STATE."
PROVISIONAL SPECIFICATION left by the said James Riley at the Office
of the Commissioners of Patents on the 10th August 1882.
JAMES RILEY, General Manager to the Steel Company of Scotland Limited, of
Glasgow, in the County of Lanark North Britain, "IMPROVEMENTS IN APPARATUS
FOR CONVEYING STEEL INGOTS IN A HEATED STATE
"
This Invention has for its object to provide for the conveyance of steel ingots
from the neighborhood of the furnaces in which the steel is made and where the
ingots are cast to the rolling or other machinery which in some kinds of steel works
is necessarily at some distance from the furnaces.
In carrying out the Invention non-conducting casings or vehicles are employed
each formed with one or more compartments for as many ingots; and after the
ingots are cast and have become sufficiently set they are separated from their
moulds and placed in the non-conducting casings or vehicles. In one modification
a specially constructed carriage on wheels is employed, being made with a frame
work of iron or other suitable material and lined with firebrick, firestone, asbestos,
or other suitable refractory material. Or instead of being lined with refractory
material the partitions of the compartments and the sides may consist of double
shells or casings of iron with asbestos or other suitable refractory material packed
in between the shells. The carriage may be formed with all the sides fixed or one
or more movable, and may be provided with a cover having a non-conducting lining
or made of a suitable non-conducting material. Or the carriage may consist
simply of a platform on wheels; and a hood may be provided for covering the
ingot or ingots during transit such hood being lined with or made principally of
non-conducting material.
In some cases as for example when one or two ingots have to be conveyed or a

an overhead traveller.
Provision may be made for heating the interiors of the casings or vehicles before
the ingots are placed in them, so that the ingots may not become too much cooled
when in them; and such heating will be conveniently secured where the furnaces
are heated by gas by arranging ducts pipes or passages with ports and valves in
such manner that the combustible gas may be led into the casing or vehicles to be
ignited therein; or hot previously ignited gases from the furnaces may be led into
them. Provision may be made for maintaining the heat in this way in the
neighborhood of the rolling or other machinery.
With the herein before described arrangements considerable economy and
advantage will arise in rolling or otherwise manufacturing the steel as the
maintenance of the heat will greatly facilitate the operations.

JAMES RILEY, General Manager to the Steel Company of Scotland, Limited, of
Glasgow, in the County of Lanark, North Britain, "IMPROVEMENTS IN APPARATUS
FOR CONVEYING STEEL INGOTS IN A HEATED STATE
"
My said Invention has for its object to provide in an improved manner for the
conveyance of steel ingots from the neighborhood of the furnaces in which the
steel is made, and where the ingots are cast, to the rolling or other machinery,
which in some kinds of steel works is necessarily at some distance from the
furnaces.
In carrying out my Invention non-conducting casings or vehicles of improved
kinds are employed, each formed with one or more compartments for as many
ingots; and after the ingots are cast and have become sufficiently set they are
separated from their moulds and placed in the non-conducting casings or vehicles.
In one modification a specially constructed carriage on wheels is employed, being
made with a framework of iron or steel, and with sides and partitions consisting
of double shells or casings of iron or steel, with ground coke, slag wool, asbestos or
other suitable non-conducting material packed in between the shells. The carriage
may be formed with all the sides fixed or one or more movable, and may be
provided with a cover having a non-conducting lining or made wholly or partly of
a suitable non-conducting material, or there may be a separate cover for each
compartment. Or the carriage may consist simply of a platform on wheels; and a
hood may be provided for covering the ingot or ingots during transit such hood
being by preference made with two iron or steel shells having a non-conducting
material packed in between them.
In some cases, as for example when one or two ingots have to be conveyed or a
number of small ones, my improved casings may be arranged to be moved by a
crane or an overhead traveller.
Provision may be made for heating the interiors of the casings or vehicles before
the ingots are placed in them, so that the ingots may not become too much cooled
when in them. Provision may also be made for maintaining the heat in the
casings, in the neighborhood of the rolling or other machinery.
And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings to
be hereinafter referred to and representing examples of my improved casings.
Figure, 1, on the accompanying sheet of drawings is a vertical section of one of
my improved casings as arranged for a single ingot and for conveying it by means
of a crane or overhead traveller from the neighborhood of the furnaces to that of
the rolling mills or other machinery. Figures 2, and 3, are side and end elevations
both partly in vertical section of an arrangement of ingot casings on wheels the
casings being permanently fixed on the platform of the carriage and being formed
with separate compartments for several ingots and having provision for heating the
compartments before introducing the ingots or for inaintaining the heat whilst the
ingots are in the compartments. Figures, 4 and 5, are side and end elevations,
the former being partly in vertical section, of a modification in which the carriage
is made with a platform on which the ingots are set on end, whilst for enclosing
each ingot there is provided a movable cover or inverted casing which is placed
over it or removed by means of a crane or other suitable hoisting apparatus. In

page_text: these drawings the same reference numerals are used to mark the same or like
parts wherever they are repeated.
The casing shown in figure, 1, is a double shelled structure made with iron or
steel plates connected by a framework of angle iron, the space, 6, between the
shells being packed with ground coke or other suitable non-conducting material.
The interior of the casing is made sufficiently large to receive the steel ingot, 7,
and so as to have a little space between the ingot and the sides, and a cover, 8, is
provided which is made double and with the space between the inner and outer
plates packed with ground coke or other suitable non-conducting material.
Chains, 9, are attached to the casing to facilitate its being moved by a crane or
overhead traveller from one part of the works to another.
The apparatus shown in figures 2, and 3, consists of a vehicle or structure
mounted on wheels, 10, and made with compartments for ten separate ingots, 7.
The bottom and sides and dividing partitions are constructed with double shells or
plates fixed to angle-iron framework and having the spaces, 6, between the shells
or plates packed with ground coke or other suitable non-conducting material. The
compartments are constructed so that the ingots, 7, can be placed on end in them,
and a cover, 11, is provided for each compartment the covers being in this example
of peculiar construction. Provision is made for heating the compartments by
means of combustible gas, and for this purpose there is formed at one end of the
vehicle a chamber, 12, lined with firebrick and fitted with a burner inlet, 13, for
gas and air. The gas enters by a side branch, 14, between which and a fixed gas
supply pipe, a temporary connecting pipe is inserted when required. The air
enters through the outer end of the burner, there being a fixed end plate and a
movable plate, 15, both formed with holes, and the quantity of air being regulated
by adjusting the movable plate to cover more or less of the holes in the fixed
plate. The chamber, 12, forms a combustion space and the top of it communicates
with the covers, 11, which are made hollow and lined with firebrick and which
are formed with passages through from one to the other, and also each with an
opening to admit the ignited gas into each compartment. From the compartments
the gas passes off by ports at the bottom, these ports being in communication
with lateral passages, 16, which may be put temporarily in communication with
flues leading to a chimney when the casings are being heated. Any one of the
covers, 11, can be replaced with a cover made without an opening into the
compartment but with a passage through it if required.
In the arrangement shown in figures, 4, and 5, the carriage is made with a plain
platform, 17, formed with two plates separated by a space, 6, which is packed
with ground coke or other suitable non-conducting material: The ingots, 7, are
set on end on this platform, 17, and are then enclosed by covers or inverted
casings, 18, of which in figure, 4, one is shown in section a second in elevation
and a third also in elevation but as partly raised. Each cover or casing, 18, is
constructed like the casing shown in figure, J, but is inverted and has fitted to its
closed end a ring bolt for the attachment of a hoisting chain.
With my hereinbefore described arrangements considerable economy and
advantage arises in rolling or otherwise manufacturing the steel as the maintenance
of the heat and the consequent rendering of the heat more uniform throughout the
ingot will greatly facilitate the operations.
Since the hereinbefore in part recited Letters Patent were applied for, I have
learned that it was previously proposed to employ for the same purposes as those
of my Invention, portable casings consisting of single shells or metal frames lined
with firebrick and therefore I do not now claim such casings as included in my
Invention notwithstanding the mention of them in my Provisional Specification
relative hereto.
Having particularly described my said Invention and the manner of performing
the same I have to state that I do not restrict myself to the precise details herein
described or delineated but that what I believe to be novel and original and claim

page_text: as the Invention secured to me by and in terms of the hereinbefore in part recited
Letters Patent is :-
1. Apparatus for conveying steel ingots in a heated state and consisting of double
metal shells having the spaces between the shells packed with ground coke or
other suitable non-conducting material, substantially as hereinbefore described.
2. Apparatus on wheels or otherwise arranged for conveying steel ingots in a
heated state in which provision is made for heating the compartments in which the
ingots are placed by means of combustible gas, substantially in the manner herein-
before described.
3. Apparatus for conveying steel ingots in a heated state consisting of a platform
on wheels combined with covers or movable inverted casings the said platform and
covers being constructed with non-conducting materials substantially as herein before
described.
In Witness whereof I, the said James Riley, have hereunto set my hand
and seal this eighth day of February in the year of our Lord One thousand
eight hundred and eighty-three,
Witness,
