Improvements in Apparatus or Plant for Preventing Loss in the
Smelting of Ores, Metals, or Compounds of Zinc or other Oxidizable
Metallic Substances, and Ores or Wastes of them.
FERRAR FENTON and ROBERT JACKSON PARTRIDGE of Batley and Grasmere
respectively Stockbroker and Financeer, in the Counties of York and Westmoreland
respectively, do hereby declare the nature of this invention to be as follows:-
The Apparatus or Plant is as delineated in the accompying drawing. As the
Protoxides or Oxides or Sulphates or Chlorates of the Metals are formed in the
furnaces of any kind deemed suitable for the Vaporization thereof they will pass into
Chamber and flue B. From thence into Pipe C. Then into a fan upon S, the said
fan being enclosed in any usual or convenient cover. The Flue B being kept
partially filled with water as indicated by the dotted water line upon the drawing to
supply steam or aqueous vapor to intermix with the passing metallic fumes or gases in
their progress to the fan upon S. A jet of water is also kept continually pouring into
the fan at S and the fan by its rapid revolutions converting the said jet of water into
spray and steam by the aid of the heated gases passing through it effects by mechanical
and chemical action a combination of the water with the metallic vapors or gases in
the form of paste or viscous substance to a considerable extent and drives the whole
forwards through tube D into the condensing well X. Any portion of the metallic
vapors or gases not combined or condensed in or by the action at the fan upon S is by
the current of air created by the said fan driven onwards through pipe P into a second
condensing well XI. The pipe P is made to dip into the water in this well so as to
cause a further deposition of the metallic fumes vapors or gases into a fixed form by
chemical and mechanical union with the water or its components. Consequently the
water in this well should always be kept to its proper level-to prevent the loss of
vapors. Any vapors fames or gases failing to be so arrested in a substantive form
at this point are conducted from X I into tube T and thence into fau
upon stand 2 §.

page_text: Here this fan 2 fed with a similar jet of water to that described above at. fan 1 effects
a second mixing of vapors and water spray or steam and drives on the compounds
formed thereby through pipe W into the basin N. Any vapors of metals.not absorbed
by Fan 2 are drawn by Fan 3 placed upon stand S 2, through the tube V which tube
is carried round the two wells X and XI. Here a third admixture with water spray
or steam or all three takes place as above described. By this last operation all metallic
fumes vapors or gases are completely exhausted from their carrying Media or nearly
so and are driven through the two tubes W W into the well N. Any part of vapors
or compounds of them which may fall back into tube V can be drawn out at the tap 8
into the basin U.
FERRAR FENTON & ROBERT JACKSON PARTRIDGE of Batley and Grasmere
respectively Stockbroker and Financier in the Counties of York & Westmoreland
respectively do hereby declare the nature of this invention and in what manner the
sanie is to be performed, to be particularly described and ascertained in and by the
following statement:-
The apparatus or plant is as delineated on the drawings with provisional specifi-
cation. As the protoxides or oxides or sulphates or chlorates of the metals are formed
in the furnaces of any kind deemed suitable for the vaporization thereof they will
pass into chamber and Hue B from thence into pipe C. Then into a fan upon S
the said fan being enclosed in any usual or convenient cover. The flue B being
kept partially filled with water as indicated by the dotted water line upon the
drawing to supply steam' or aqueous vapor to intermix with the passing metallic
fumes or gases in their progress to the fan upon S. A jet of water is also kept
continually pouring into the fan at S and the fan by its rapid revolutions converting
the said jet of water into spray and steam by the aid of the heated gases passing
through it effects by mechanical and chemical action a combination of the water with

page_text: the metallic vapors or gases in the form of paste or viscous substance to a considerable
extent and drives the whole forwards through tube D into the condensing well X.
Any portion of the metallic vapors or gases not combined or condensed in or by
the action at the fan upon S is by the current of air created by the said fan
driven onwards through pipe P into a second condensing well XI. The pipe P is
made to dip into the water in the well so as to cause a further deposition of the
metallic fumes vapors or gases into a fixed form by chemical and mechanical union
with the water or its components; consequently the water in this well should always
be kept to its proper level to prevent the loss of vapors. Any vapors fumes or gases
failing to be so arrested in a substantive form at this point are conducted by XI
into tube and thence into fan 2 upon stand 2 S. Here this fan 2 fed with a
similar jet of water to that described above at fan 1 effects a second mixing of
the metalic vapors with water and spray or steam of water and drives on the compounds
formed thereby through pipe V which pipe V is carried round the two tanks XI
& X to the fan 3 which is placed also upon stand S 2 and are impelled into and
through the pipe W into the well N.
By this last operation all the metalic fumes vapors or gases are completely exhausted
from their carrying media or nearly so. The pipe W D is an outlet to releive the
tube V from the metalic mud or Protoxide which would otherwise collect in
pipe V and choke the Fan-which said pipe W D deposits the Protoxide into the
well N.
Any portion of the Protoxide or metalic mud which may lodge at the bottom of
the incline of the tube V where it passes round the tank X can also be drawn out at
tap or vent 8 into the basin U.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim as our invention is
The condensation of the vapors or gaseous compounds of zinc or other vaporizable
metals by the aid of water spray and steam intermixed with atmospheric air
and driven onward by means of fans or dashers through and into enclosed or
confined vessels or stills or pipes or all combined so as to recover the metallic
elements in the said vapors or gaseous compounds in a solid form, for their
subsequent conversion into maleable or fusible metals. The plant which we use for
the purpose being that described in this specification and in certain drawings referred
to herein and lodged in the Royal Patent Office.
The metallic vapors being recovered as protoxides or oxides in the form of paste.
