IMPROVEMENTS IN THE MANUFACTURE OF BAR IRON
Year: 1885

page_text: PROVISIONAL SPECIFICATION.
I JOB GILLIGAN of 20 Castle Street, Abertillery near Newport in the County
of Monmouth, Forge Manager do hereby declare the nature of my invention for
IMPROVEMENTS IN THE MANUFACTURE OF BAR IRON to be as follows:-
These improvements relate to the production of Bar Iron from which it is
intended to manufacture Tin and Terne plates or for other purposes requiring a
similar quality of iron, and consist in taking a slab direct from the hammer while
hot and reducing its sectional area in a suitable pair of rolls before it is taken to
the ball furnace, thus a larger surface area is exposed to the action of the heat
in the ball furnace, whereby the purity and softness of the iron obtained is
augmented.
In carrying out this invention puddled or other iron of suitable quality is
hammered into a slab of any convenient shape, it is then removed from the
hammer while hot and passed through rolls until it is reduced to the required
sectional area. It is then taken (either hot or cold as may be most convenient)
to a ball furnace where it is heated and afterwards passed through rolls and
reduced to a finished bar ready for the mills.
The reduced slabs may be worked either singly or cut through the middle and
doubled in a ball furnace according to the quality of iron required.

same is to be performed to be particularly described and ascertained in and by
the following statement:-

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
In the manufacture of Bar Iron for Tin and Terne plates, and for other purposes
requiring a similar quality of Iron. Taking a slab direct from the hammer while
hot and reducing its sectional area in a suitable pair of rolls before it is taken to
the ball furnace, thus presenting a larger surface to the action of the heat in the
ball furnace whereby the purity and softness of the iron obtained is augmented.
