PROVISIONAL SPECIFICATION left by the said August Frederick William
Partz at the Office of the Commissioners of Patents, with his Petition,
on the 10th February 1857.
I, AUGUST FREDERICK WILLIAM PARTZ, of the City and State of New
York, in the United States of America, do hereby declare the nature of the
said Invention for "AN IMPROVED METHOD OF EVAPORATING FLUIDS, CONDENSING
AND ABSORBING VAPORS, GASES. AND FUMES, ARRESTING AND PRECIPITATING
FLOCULENT, METALLIC, OR OTHER PARTICLES, AND TRANSFERRING HEAT FROM AIR
OR STEAM TO FLUIDS AND PULVERULENT SUBSTANCES," to be as follows:-
The said Invention consists in making use of discs of interlaced wire,
perforated or solid plates of metal, fibrous substances, or other equivalent
materials, which are either by a rotary or reciprocating motion alternately
immersed in and withdrawn from a fluid, a film of which adhering to them
they successively present to a current of air or steam of any required' tem-
[Price 8d"

page_text: perature for the purpose of evaporation, or to vapors, gases, fumes, floculent,
metallic, or other particles, etc., for their condensation, absorption, or pre-
cipilation, or which perforated discs, or plates, or fibrous substances, are
permanently immersed in a fluid, and a current of air, steam, vapors, gases,
or fumes, is forced through them, whereby said current is broken and diffused,
and said gaseous bodies are brought intimately into contact with the fluid, for
the respective purposes hereafter set forth; or which perforated discs or
plates, etc. are by a rotary or reciprocating motion, alternately immersed in
and withdrawn from a fluid or pulverulent mass, for transferring to the
latter the heat which they take up from a current of hot air or steam
that is directed upon them while withdrawn from said fluid or pulverulent
nass.
It will be perceived, that by this method fluids may be brought effectively
into contact with air or steam for the purpose of evaporation, or with vapors,
gases, fumes, or floculent, metallic, and other particles for their respective
condensation, absorption, or precipitation, by means of an extensive develope-
nent of the liquid surface within, a comparatively small compass, and
otherwise as above specified, and also fluids and pulverulent substances may
be heated indirectly by means of a current of hot air or steam and a trans-
ferring medium.
This method and apparatus for evaporating fluids, and condensing, ab-
sorbing, and precipitating vapors, gases, fumes, floculent, metallic, or other
particles, etc. are to be applied to any purposes in the arts for which they may
be available.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed

page_text: said August Frederick William Partz, 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 "AN IMPROVED METHOD OF EVAPORATING FLUIDS, CONDENSING
AND ABSORBING VAPORS. GASES. AND FUMES. ARRESTING AND PRECIPITATING
FLOCULENT. METALLIC. OR OTHER PARTICLES. AND TRANSFERRING HEAT FROM
AIR OR STEAM TO FLUIDS AND PULVERULENT SUBSTANCES," upon the condition
(amongst others) that I, the said August Frederick William Fartz, by an
instrument in writing under my hand and seal, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same
was to be performed, 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.
1
NOW KNOW YE, that I, the said August Frederick Willian Partz, do
hereby declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto annexed
and to the letters and figures marked thereon (that is to say):-
1
Fig. 1 is a vertical longitudinal section; and Fig. 2 is a vertical cross
section of the apparatus which is principally adapted to the above purposes.
The said Invention consists in making use of discs of woven wire, per-
forated plates of metal, fibrous substances, or other equivalent material, which
are either by a rotary or reciprocating motion, alternately immersed in and
withdrawn from a fluid, a film of which adhering to them they successively
present to a current of air or steam of any required temperature for the
purpose of evaporation, or to vapors and gases for their condensation or
absorption, or for the precipitation of metallic or other particles mixed
therewith and floating therein; or which perforated discs, or plates or fibrous
substances are permanently immersed in a fluid, and a current of vapors or
gases is forced through them, whereby said current is broken and diffused,
and said vapors or gases are brought intimately into contact with the fluid,
for the respective purposes set forth; or which perforated disks or plates,
&c, are, by a rotary or reciprocating motion, alternately immersed in
and withdrawn from a fluid or pulverulent mass, for tranferring to the
latter the heat which they take up from a current of hot air or steam
that is directed upon them while withdrawn from said fluid or pulverulent
mass."

In the Drawing a is a vessel made of sheet iron or any other suitable
material; through this vessel a shaft 6 passes, which is supported in journals
c, c, and driven at the desired speed by power applied to the pulley d, or
otherwise, in any convenient manner; e, e, e, are disks of woven wire, per-
forated metal, fibrous substances, or other equivalent material, attached to
the said shaft by means of interposed circular blocks of wood f,f,f, and heads
and rods g,g; h is a semicylindrical hood, which encloses the upper halves
of the discs e, e, e, nearly in contact with their peripheries.
The operation is as follows:-The vessel a being filled with the liquid to
be evaporated, or the absorbing liquid, to about the height shewn, the discs
e, e, e, elevate and suspend by their revolution, a film of the liquid which
adheres to them, and present the same to the vapors or gases that are led
into the hood by means of the pipe , or in any other suitable manner;
thus, evaporation, condensation, absorption, and precipitation are respectively
promoted.
If the vessel, a contains a solution to be evaporated, as cane juice, brine,
etc., a current of dry or heated air is forced through the apparatus by means
of a blast generator, or otherwise, and having penetrated said perforated disks
and become saturated with the vapors of the solution, escapes through the
trunk or pipe k. As the bulk of the liquid diminishes by evaporation, it
should be supplied from a reservoir, and thus be kept nearly at its original
elevation. In the condensation of steam from low pressure engines, the
vessel a which contains the condensing water, should be tightly closed, and
the trunk or pipe made to. communicate with an air pump, such as is
generally employed for the exhaustion of the air associated with the steam.
If the apparatus be.used as a mere water heater in connection with high-
. pressure engines, the trunk or pipe k serves for the escape of the surplus
steam. In the adaptation of this apparatus to the various purposes above
specified, additional fixtures for the introduction or discharge of the vapors or
gases, or for the supply and removal of the evaporating or absorbing liquids,
or for the collection and separation of sediments may be required, which it is
unnecessary here to specify, as any person skilled in the arts will know,
without special advice,how to attach such fixtures in order to accomplish said
objects. Instead of discs, screw-formed plates or wings of perforated metal,
&c. may be substituted with the same effects.
It will be perceived that by this method an extensive liquid film will be
continuously developed within a comparatively small space, and vapors or
gases be conveniently and effectually brought into contact with said film, for
the purpose either of saturating solutions by evaporation, or of condensing

page_text: steam, or of transferring heat from gases to fluids, or of uniting gases with
fluids in various chemical manufactures, or of arresting and precipitating the
products of imperfect combustion, metallic, or other particles, suspended in
air and gases, etc. The temperature of a pulverulent mass contained in the
vessel a may be elevated for drying or other purposes, by a current of heated
air, or a flame being led into the apparatus, and the caloric taken up by the
perforated discs transferred to said mass.
This method and apparatus for evaporating liquids, and also of condensing
and absorbing vapors and gases, arresting and precipitating metallic or other
particles mixed therewith and floating therein, and transferring heat from air
or steam to fluids and pulverulent substances are to be applied to any
purposes in the arts for which they may be available.
What I claim as my Invention, and desire to secure by Letters Patent is,
the method herein described of evaporating liquids, and also of condensing
and absorbing vapors and gases, arresting and precipitating metallic or other
particles mixed therewith and floating therein, and transferring heat from air
or steam to fluids and pulverulent substances by the use of perforated disks,
plates, or sheets, substantially in the manner specified.
In witness whereof, I, the said August Frederick William Partz, have
hereunto set my hand and seal, this Seventh day of July, in the year
of our Lord One thousand eight hundred and fifty-seven.
