IMPROVEMENTS IN MACHINERY FOR PUDDLING IRON AND STEEL IRON
Year: 1864

page_text: LETTERS PATENT to James Eastwood, of Litchurch, near Derby, in the
County of Derby, Engineer, for the Invention of. "IMPROVEMENTS IN
MACHINERY FOR PUDDLING IRON AND STEEL IRON."
PROVISIONAL SPECIFICATION left by the said James Eastwood at the
Office of the Commissioners of Patents, with his Petition, on the
27th May 1864.
I, JAMES EASTWOOD, of Litchurch, near Derby, in the County of Derby,
Engineer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY FOR PUDDLING IRON AND STEEL IRON," to be as follows:-
My Invention consists in the arrangements of machinery hereafter described.
Over an ordinary pudling furnace I place a shaft, on which there is a crank
connected by a connecting rod to the short end of a bent lever, the other or
long end of the lever hangs down in front of the furnace for the puddling
rabble to be attached to it; this lever has its fulcrum in an arm projecting
upwards and outwards over the front of the furnace; the bottom of this arm
rests in a socket to allow it to turn from side to side, which turning is effected
by being connected by a rod to a pin carried in a worm wheel, which revolves
on a fixed stud, and is set in motion by a worm upon the shaft before named.
The whole is secured together on a bracket or bed plate with the necessary.
pedestals, and is supported on the furnace in an ordinary way.

page_text: The action of the machine is as follows:-Motion being given to the shaft
the crank through the connecting rod works the lever, and the rabble being
attached is drawn to and fro, or from back to front of the furnace, and thus
stirs the molten metal, and is made to traverse from the flue bridge to the
fire bridge of the furnace by means of the worm on the shaft turning the
wheel; the pin carried by the wheel being connected to the arm turns the
arm to the side next the flue bridge, and back to the side next to the fire
bridge on every turn of the worn wheel.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Eastwood in the Great Seal Patent Office on the 26th-
November 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
EASTWOOD, of Litchurch, near Derby, in the County of Derby, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of May, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said James Eastwood, Her special licence that I, the said James
Eastwood, my executors, administrators, and assigns, or such others as I, the
said James Eastwood, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN MACHINERY FOR PUDDLING IRON AND STEEL IRON," upon the condition
(amongst others) that I, the said James Eastwood, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said James Eastwood, do hereby declaro
the nature of my said Invention, and in what manner the same is to be per-
formned, to be particularly described and ascertained in and by the following

page_text: statement thereof, reference being had to the Drawing hereunto annexed, that
is to say:-
My Invention consists in the arrangements of machinery herein-after
described. Over an ordinary puddling furnace I place a shaft, on which there
is a crank connected by a connecting rod to the short end of a bent lever, the
other or long end of the lever hangs down in front of the furnace for the
puddling rabble to be attached to it; this lever bas its fulerum in an arm
projecting upwards and outwards over the front of the furnace; the bottom of
this arm rests in a socket to allow it to turn from side to side, which turning
is effected by being connected by a rod to a pin carried in a worm wheel
which revolves on a fixed stud, and is set in motion by a worm upon the shaft
before named; 'the whole is secured together on a bracket or bed plate
with the necessary pedestals, and is supported on the furnace in an ordinary
way.
The accompanying Drawing represents a puddling machine constructed
according to my Invention.
A is a bed plate or bracket supported on the furnace, and carrying
bearings B, B, for a shaft C; the shaft C has keyed on to it a crank D con-
nected by a connecting rod E to the short arm of a bent lever F, the other or
longer arm of this lever hangs down, as shewn, in front of the furnace for the
puddling rabble G to be attached to it; the lever F has its fulcrum in an
arm H projecting upwards and outwards over the front of the furnace; the
bottom of the arm H rests in a socket in the bed plate A to allow it to turn
from side to side; the turning of the arm H is effected by its being connected
by a rod I to a pin J carried on a worm wheel K, with an uneven number of
teeth; the wheel K revolves on a fixed stud M, and is set in motion by a
worm N on the shaft C; the machine is driven by a chain or band O passing
over a pulley P on the shaft C, it is put into and out of gear as required by a
hand lever Q and clutch R. Or instead of chain or band the machine may be
driven by toothed gear. The action is as follows:-Motion being given to the
shaft C, the crank D through the connecting rod E works the lever F, to
which the rabble G is attached; the rabble is thus drawn to and fro or from
back to front of the furnace; it is also made to traverse from one jamb
to the other by the worm N turning the wheel K connected by the rod I to
the arm H; every turn of the wheel K, owing to the uneven number of teeth,
alters the position of the arm H, and the rabble is each time sent in a different
direction or over a different part of the furnace bottom, whereby every part of
the furnace bottom is in turn worked over.
And having now described the nature of my said Invention, and in what

page_text: manner the same is to be performed, I declare that I claim, arranging.
machinery for puddling iron and steel iron substantially as herein-before
described and illustrated in the accompanying Drawing.
In witness whereof, I, the said James Eastwood, have hereunto set
my hand and seal, this Twenty-third day of November, One thousand
_ eight hundred and sixty-four.
JAMES EASTWOOD. (L.S.)
