page_text: LETTERS PATENT to Baldwin Fulford Weatherdon, of 77, Chancery Lane,
in the County of Middlesex, Civil Engineer and Patent Agent, for the
Invention of ". IMPROVEMENTS: IN APPARATUS FOR PREVENTING INCRUSTA-
TION IN STEAM BOILERS."-A communication from abroad by Joseph Toth.
PROVISIONAL SPECIFICATION left by the said Baldwin Fulford
Weatherdon at the Office of the Commissioners of Patents, with his
Petition, on the 27th June 1866.
1, BALDWIN FULFORD WEATHERDON, of 77, Chancery Lane, in the County of
Middlesex, Civil Engineer and Patent Agent, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN APPARATUS FOR PREVENTING INCRUSTA-
TION IN STEAM BOILERS," (a communication from abroad by Joseph Toth, of
Kecskemés, in the County of Pesth, Hungary, in the Empire of Austria,) to
be as follows (that is to say) :-
The Invention has reference to improvements in apparatus for depriving
the feed water of boilers of the feculent or foreign matters contained therein,
and thereby preventing incrustation or deposit, maintaining thereby greater
economy of fuel and uniformity of surface heat within the boiler than at
present, and consists of an upright cylindrical vessel 18 feet high by 6 feet in
diameter, divided horizontally in two compartments, the upper one filled with

page_text: feed water to the depth of twelve feet, whilst the lower one, in connection
with a series of copper tubes passing vertically through the said water, is
charged with steam, by which the said water is caused to boil and pass off in
its heated state through the medium of open or closed gutters or pipes (direct
to the boiler tank), depositing in its passage through the said gutters the
sulphates, carbonates, and other salts of lime, magnesia, mud, or other solids,
or incrustating sediment or furs; the flow or supply of water to the apparatus
being maintained through the medium of a pump from a well or other source,
and supplied as above in a pure state to the boiler.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Baldwin Fulford Weatherdon in the Great Seal Patent
Office on the 22nd December 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BALDWIN
FULFORD WEATHERDON, of 77, Chancery Lane, in the County of Middlesex,
Civil Engineer and Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of June, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Baldwin Fulford Weatherdon, Her special licence that I, the said
Baldwin Fulford Weatherdon, my executors, administrators, and assigns,
or such others as I, the said Baldwin Fulford Weatherdon, 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 "IMPROVEMENTS IN APPARATUS FOR PREVENTING
INCRUSTATION IN STEAM BOILERS," being a communication from abroad, upon the
condition (amongst others) that I, the said Baldwin Fulford Weatherdon, my
executors or administrators, 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 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.
NOW KNOW YE, that I, the said Baldwin Fulford Weatherdon, do hereby
.declare the nature of my said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by the
following statement, and the Drawings therein referred to (that is to
say):
This Invention has reference to improvements in apparatus for depriving the
feed water of boilers from all feculent or foreign matters contained therein, by
which incrustation or deposit is prevented from forming within the said.boilers,
whereby greater economy of fuel and uniformity of surface heat is maintained
than at present, and consists in the employment of an upright cylindrical
vessel eighteen feet high by six feet in diameter, divided horizontally in two
compartments, the upper one furnished with vertical copper tubes surround
with water to the depth of twelve feet, whilst the lower one supplied with
steam from the waste pipe causes the said water to boil and pass off in
its heated state through the medium of a tube into a trough composed of
intervening gutters, depositing on its passage through the same the carbonates,
sulphates, or other salts of lime, magnesia, mud, or other solids, incrustating
sediments or furs, and finally passing direct to the boiler tank; the flow or
supply of water to the apparatus being maintained through the medium of a
pump from a well or other source, and delivered by the above-mentioned
process in a pure state to the boiler.
But in order that my said Invention may be more fully understood and readily
carried into effect I now proceed to describe the same by the aid of the
accompanying Drawing, reference being had to the letters and figures
thereon marked (that is to say):
Fig. 1 represents a front view of the cylindrical boiler employed in my
purifying apparatus; Fig. 2, a vertical section thereof; Fig. 3, top or plan
view with part of the upper portiou removed so as to shew the internal tubular
arrangement; and Fig. 4 a perspective view of the apparatus complete
shewing its mode of working in connection with steam machinery. In each
Figure the same letters of reference denote similar corresponding parts.
A, A, sheet-iron cylinder; B, B, funnel top or dome of same for the
escape of steam; C, C, steam chamber formed in the lower part of the said
cylinder; D, steam pipe; E, E, boiler or upper division of the said cylinder
filled with water; F, F, G, G, copper tubes through which the steam passes
in the direction of the arrows for communicating heat to the water; H and H¹,
upper and lower diaphragms containing said tubes; I, I, outlet from which
the boiling water passes to the purifier; J, J, filtering apparatus composed of
a combination of gutters resting on a wooden base, through which the boiling
water from the tubular cylinder A is caused to flow and deposit its sediment
or otherwise within the cellular gutters, as represented in Fig, 4; K, K,

page_text: cover for enclosing the upper portion of the said filtering apparatus as required;
L, L, pipe for conveying the said filtered or purified water to the boiler tank
M, M; N, N, the purified water for feeding the boiler; O, O, pump for
supplying the said cylinder with water; P, P, engine for giving motion to the
same; Q, Q, well from which the water is drawn; R, R, injector for sup-
plying the steam boiler S, S.
In conclusion to the foregoing description I would here briefly note that
one or more of the said cylinders may be employed in connection with the
above system, and that the said cellular gutters may be lengthened or other-
wise, and constructed or composed of any suitable material as may be found
necessary.
And I would further note that by the above process the purified water may be
employed as aforesaid, without involving any cleansing of the boiler through
incrustation or otherwise.
Having now fully described and ascertained the nature of this my said
Invention, and the manner in which the same is to be performed and carried
into effect, I would have it clearly understood that I do not intend to confine
myself to the precise details herein-before described, as the same may be
otherwise varied without departing from the general principle of this my said
Invention, nor do I claim as new and of my said Invention the exclusive use
of the several parts, combinations, and processes herein-before described,
except when the same are employed in and for the purposes of my said
Invention, which I hereby declare to consist in depriving water of its feculent
or other impurities through the medium and employment of the above-
mentioned process, in the manner and for the purposes herein-before set forth
and described.
In witness whereof, I, the said Baldwin Fulford Weatherdon, havo
hereunto set my hand and seal, this Twenty-second day of December,
in the year of our Lord One thousand eight hundred and sixty-
six.
