of the Commissioners of Patents, with his Petition, on the 15th February
1859.
FREDERICK WALTERS, of Sheffield, in the County of Yorkshire, do hereby
declare the nature of the said Invention for "THE APPLICATION OF THE WASTE
HEAT FROM PUDDLING FURNACES," to be as follows:-
By reference to the annexed Drawings, it will be seen Plan 1 represents a
common puddling furnace with a converting furnace attached, which it is pro-
posed to be work'd from the waste heat of the puddling furnace.. No. 1 on
the Plan is the fire; No. 2, the bed for puddling; No. 3, chimney for
puddling furnace for taking away the heat when not wanted through the con-
verting furnace; No. 4, openings for cleaning away waste dross or ashes;
No. 5, damper of fire-bricks for regulating the draughts or shutting off entirely
the heat from the converting furnace, or shutting off the heat from chimney
No. 8, so as to cause the same to pass through the converting furnace; No. 6,
flues connected with the puddling furnace, to convey the heat from the pud-
dling furnace under and around the converting pots, and made to terminate
at No. 7 chimney; No. 8 is the ordinary converting pot, and fixed over flue
No. 6, with fire-brick arches under, as shown in section A, B, to protect the
pots from the direct action of the blast.
Plan 2 represents a common puddling furnace, as in Plan 1, with a
melting furnace attached, No. 1 to No. 4, as described on Plan 1. Nos. 5,
dampers of fire-bricks, made for regulating the draughts or shutting off

page_text: entirely the heat from the melting furnace; No. 6 flue from puddling furnace
to supply heat to the pots No. 7. No. 7 are the common steel melting pots
fixed in a common steel melting furnace. No. 6 flue is made to communicate
with the back of steel furnace and supply additional heat, which is to pass
through the fire and terminate in flue No. 8.
Plan 1 represents a single converting pot, but it is proposed to add any
number of pots, or attach more than one puddling furnace, or to make the pots
of any dimensions, or to fix them in any position to suit the size of the
puddling furnace or. the power of waste heat, so that there can be two
puddling furnaces or more to one pot, or one puddling furnace to two pots or
more, as the case may be.
Plan 2 represents two furnaces for melting steel, each furnace containing
two pots, but it is proposed to add any number of furnaces in one line, or a
double line, or to attach more than one puddling furnace to the steel furnaces;
the heat from the puddling furnaces is to pass through the fire of the melting
furnace, above the bars, and so work round the pots, and add considerably to
the heat of the furnace and save a large amount of fuel. It will be seen by
the above descriptions and accompanying Plans that it is intended to protect
the application of the waste heat from puddling furnaces, or any other furnaces
of a similar description, (given under any other name) for heating, converting,
or melting furnaces, gas retorts, boilers, or any furnaces requiring less heat
than a puddling furnace.
