PROVISIONAL SPECIFICATION.
Improvements in the Arrangement and Construction of Foundries
for the Casting of Steel.
I, ROBERT ABBOTT HADFIELD, of Parkhead House, Sheffield, in the County of
York, Steel Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My improvements are intended to facilitate the operations involved in casting
steel by such an arrangement and construction of the foundry as shall economise
the labour of handling the moulds and molten metal, the time taken up in
the operations, and the space occupied by the requisite buildings and plant.
In foundries as heretofore operated the operations of forming the moulds and
casting the metal are attended with inconveniences resulting from the limited
access to the drying stove, to which both the moulders and the men occupied in
the actual casting of the metal have recourse; the moulders for the purpose of
feeding in the moulds to be dried and the casters for the purpose of obtaining the
moulds when ready for use.
According to my invention I obtain a novel arrangement of the foundry in
which the mould shop is separated from the casting shop and a drying stove,
or; as the case may be, a range of drying stoves; is interposed between them.
In order to fit the drying stove to occupy this position I provide a form of
stove having doors at both back and front, these doors opening into the casting
shop and the mould shop respectively. The stoves are provided with suitable
railways extending entirely through them, so that the bogies carrying the moulds
can be run in from the mould shop and run out into the casting shop without
leaving the rails and without change of the direction of their travel and without
establishing any free communication between the mould shop and the casting
shop.
In this way I am able to secure many important advantages tending to
accomplish the results above stated. Thus I avoid the crowding and tendency to
confusion and danger commonly experienced when the moulding and the casting
operations are both carried on in one shop and am able to secure improved ventila-
tion of the moulding shop. I am able also to arrange the appliances in each
shop with exclusive regard to the work carried on in that department of the
foundry and thus to secure the highest efficiency in respect both of space occupied
and machinery employed with a corresponding economy of labour and in a manner
to facilitate regular and systematic working.

for the Casting of Steel.
I, ROBERT ABBOTT HADFIELD, of Parkhead House, Sheffield, in the County of
York, Steel Manufacturer, 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: —
My improvements are intended to facilitate the operations involved in casting
steel by such an arrangement and construction of the foundry as shall economise
the labour of handling the moulds and molten metal,, the time taken up in
the operations, and the space occupied by the requisite buildings and plant.
In foundries as heretofore operated the operations of forming the moulds and
casting the metal are attended with inconveniences resulting from limited access
to the drying stove, to which both the moulders and the men occupied in the
actual casting of the metal have recourse; the moulders for the purpose of feeding
in the moulds to be dried and the other men for the purpose of obtaining the
moulds when dried and ready for use.
According to my invention I obtain a novel arrangement of foundry in
which the mould shop is separated from the casting shop and a drying stove,
or; as the case may be, a range of drying stoves, is interposed between them.
In order to fit the drying stove to occupy this position I provide a form of
stove having doors at both back and front, these doors opening into the casting
shop and the mould shop respectively. The stoves are provided with suitable
railways extending entirely through them so that the trolleys carrying the moulds
can be run in from the mould shop and run out into the casting shop without
leaving the rails and without change of the direction of their travel and without
establishing any free communication between the mould shop and the casting
shop.
Referring to the accompanying illustrative drawings,
Fig. 1 shows in sectional elevation and,
Fig. 2 in sectional plan, an improved foundry arrangement according to my
invention.
a, a is the moulding shop, separated from the casting shop 6 by a drying stove c,
or, as the case may be, a range of drying stoves, which is constructed with doors d
and e respectively at the front and at the back of the stove or range of stoves.
The door or doors d opens or open into the moulding shop a and the door or
doors e opens or open into the casting shop b. f, is a railway extending entirely
through the stove (see Fig. 2) and g is a trolley adapted to carry the moulds and
to run on the railway f.
h and represent travelling cranes by which, or equivalent appliances, the
moulds can be placed on and removed from the trolleys g.
In a foundry arranged and constructed as described I am able to secure many
important advantages tending to accomplish the results hereinabove stated.
As in the moulding shop a there is not any molten metal, the moulders are
enabled to do their work uninterruptedly and without danger, the mould is
placed on the trolley g, the door is opened, the trolley is wheeled into the
stove c, then the door is closed; when the mould is sufficiently dry, the door e is
opened, the trolley g with the dried mould on it is wheeled out of the stove c into
the casting shop 6 and there the mould is removed from the trolley, and is
suitably prepared (as well understood) and the casting is effected. Thus I avoid
the crowding and tendency to confusion and danger commonly experienced when

page_text: the moulding and the casting operations are both carried on in one shop, and
am able to secure improved ventilation of the moulding shop. I am able also to
arrange the appliances in each shop with exclusive regard to the work carried on in
that department of the foundry and thus to secure the highest efficiency in respect
both of space occupied and machinery employed with a corresponding economy of
labour and in a manner to facilitate regular and systematic working.
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:
1. A foundry for casting steel, wherein the mould shop is separated from the
casting shop and a drying stove or a range of drying stoves is interposed between
them, provided with a door or doors at the front of the stove or range of stoves
leading from the casting shop into the stove or stoves and with another door or
other doors at the back of the stove or range of stoves leading into the casting
shop, the construction arrangement and mode of working being such that
the operations of moulding drying the moulds, and casting are kept separate
and can be conducted in regular and consecutive order substantially as described
for the purpose specified.
2. In the casting of steel the use in manner set forth of appliances constructed
combined and arranged in a foundry as hereinabove described with reference to
the accompanying illustrative drawing, for the purpose specified.
