Separately or Together in a Puddling Furnace.
I, JOB GILLIGAN of Brighton Villas, Abertillery, in the county of Monmouth, Forge
Manager, do hereby declare the nature of this invention to be as follows:-
My invention for improvements in the working up of scrap iron and steel, either
separately, or together, in a puddling furnace has for its principal object to work up
the scrapiron and steel sheared from plates prepared for the manufacture of tin and terne
plates, but is also equally applicable for working up any other scrap iron or steel;
and consists, in balling up the said scrap iron or steel in the molten metal in the
puddling furnace before the metal is on the full boil.
In carrying out my invention I employ any ordinary single or double puddling
furnace, charged with metal, and when the said charge is melted I introduce the scrap
iron or steel to be balled either, loose or in bundles into the furnace where it is heated
and balled up in the usual manner; the balls are then placed in the most convenient
part of the furnace while the puddler works up the metal. During the whole time
that the metal is being worked the scrap balls are moved about the bed of the furnace
until a sufficient quantity of the puddled iron has adhered to them, and each scrap
ball has become encased with the puddled iron; the balls are then ready for the
hammer or squeezer as the case may be.
As scrap iron or steel readily unites in any proportion with puddled iron, any
quality of metal may be used in this process according to the quality of the finished
material required.
It will also be seen that the scraps are thrown in and balled up without any loss in
yield to the metal in the furnace, owing to the metal in the puddling furnace being
coated with liquid cinder.
One or more scrap balls may be worked in each heat of puddled iron.
The quantity of fettling required is greatly reduced by this process, also, the tap
cinder from the puddling furnace is very much reduced in quantity and improved in
quality.

I, JOB GILLIGAN of Brighton Villas, Abertillery, in the county of Monmouth, Forge
Manager, 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 invention for Improvements in the working up of scrap iron and steel either
separately or together in a puddling furnace, has for its object to reduce the time and
labour required in the puddling process, and is more especially designed for the working
up of scrap iron and steel sheared from plates prepared for the manufacture of tin and
terne plates, but is also equally applicable for working up any other scrap iron or steel;
and consists in balling up the said scrap iron or steel in the molten metal in the
puddling furnace before the metal is on the full boil.
In carrying out my invention I employ any single or double puddling furnace
charged with metal, and when the said charge is melted, I introduce the scrap iron or
steel to be balled, either loose or in bundles into the furnace where it is heated and
balled up in the usual manner; the balls are then placed in the most convenient part
of the furnace while the puddler works up the metal. During the whole time that the
metal is being worked the scrap balls are moved about the bed of the furnace until a
sufficient quantity of the puddled iron has adhered to them, and each scrap ball has
become encased with the puddled iron; the balls are then ready for the hammer or
squeezer as the case may be.
As scrap iron or steel readily unites in any proportion with puddled iron, any
quality of metal may be used in this process according to the quality of the finished
material required.
It will also be seen that the scraps are thrown in and balled up without any loss in
yield to the metal in the furnace, owing to the metal in the puddling furnace being
coated with liquid cinder.
One or more scrap balls may be worked in each heat of puddled iron.
The quantity of fettling required is greatly reduced by this process, also the tap
cinder from the puddling furnace is very much reduced in quantity and improved in
quality.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
The method of working up scrap iron and steel, consisting in balling up the
scrap iron or steel or mixture of iron and steel in molten metal in a puddling
furnace before the metal is on the boil substantially as described.
