Richards at the Office of the Commissioners of Patents, with their
Petition, on the 13th May 1859.
We, JOSEPH FELIX ALLENDER, of Brierley Hill, in the County of Stafford,
Manager of Works, and JOB RICHARDS, the younger, of Brierley Hill aforesaid,
Manager of Works, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN FURNACES FOR PUDDLING IRON," to be as follows:-
Our Invention consists in giving the puddling furnace, or that part of the
furnace in which the puddling is effected, an oscillatory motion or a rotatory
motion, or a semi-rotatory or rolling motion. The said motion of the furnace,
combined with the motion of the puddling tool or tools, effectually and
economically puddles the fused cast iron in the said furnace.
When we carry our Invention into effect by giving an oscillatory motion to
the furnace, we construct the said furnace as follows:-The said furnace is so
shaped that one portion is vertical, and the other portion horizontal. The
vertical part of the furnace carries the fire-place or fire-places, and the hori-
zontal part forms the bed upon which the iron is puddled. The said vertical
limb of the furnace turns upon a horizontal axis, and that end of the horizontal
limb of the furnace furthest from the vertical limb is suspended by a chain to.
a crank or face plate, by the rotation of which crank or face plate an oscillatory
motion is given to the furnace, the said furnace having motion in a vertical
plane upon the before-mentioned horizontal axis. By the joint motion of the
furnace and puddling tools, the cast iron in the furnace is agitated and
effectually puddled.

page_text: Instead of a crank or face plate for giving to the furnace the oscillatory
motion described, any other convenient mechanism may be used.
Instead of making the furnace single, the said furnace may be made double,
or other convenient number of furnaces may be combined together and turn
upon the same axis. When we combine two or more furnaces together, we
prefer so to arrange them that the heat from one furnace shall pass to the second,
and from the second to the third, and so on, as it may suit best. When we
carry our Invention into effect by giving a rotatory or semi-rotatory motion to
the furnace, we prefer to construct the furnace as follows:-We give that part
of the furnace in which the puddling is effected somewhat of a spiral figure.
Oue limb of the furnace turns in bearings made in the fire-place, from which
the furnace derives its heat, and the other limb of the furnace turns in bearings
made in the culvet or stack of the furnace. By giving a rotatory or semi-
rotatory motion to the spiral part of the furnace, the fused cast iron therein is
agitated, and the puddling of the said iron facilitated.
We sometimes modify the last described furnace by giving to that part of
the furnace in which the iron is puddled a cylindrical figure, and inclining it to
about an angle of forty-five degrees. The said furnace turns in bearings made
in the fire-place and stack, as already explained with reference to the last
described furnace.
Although we prefer giving motion to the puddling furnace by the methods
described, yet other methods of giving it motion may be resorted to with the
same or nearly the same effect.
