page_text: LETTERS PATENT to Louis Emile Constant Martin, of No. 32, Albion
Street, Hyde Park, in the County of Middesex, for the Invention
of "IMPROVEMENTS IN APPARATUS FOR SUPPLYING WATER TO STEAM
BOILERS
Sealed the 5th July 1864, and dated the 12th January 1864.
PROVISIONAL SPECIFICATION left by the said Louis Emile Constan
Martin at the Office of the Commissioners of Patents, with his
Petition, on the 12th January 1864.
I, LOUIS EMILE CONSTANT MARTIN, of No. 32, Albion Street, Hyde Park,
in the County of Middlesex, do hereby declare the nature of the Invention
for "IMPROVEMENTS IN APPARATUS FOR SUPPLYING WATER TO STEAM BOILERS,"
to be as follows:-
This Invention has for its object improvements in apparatus for supplying
water to steam boilers. For these purposes the water which is to be supplied
to a steam boiler is caused first to pass in a highly divided state in the form
of rain or numerous small streams into a vessel, wherein are placed perforated
shelves either in horizontal or inclined positions. Superheated steam at the
pressure of the steam in the boiler is caused continually to enter at the lower
part of this vessel so as to meet and mix with the descending drops or streams
of water, by which the water will be highly heated and some part thereof
evaporated, whilst the impurities which would incrust and settle on the boiler,
if the witer be supplied directly to the boiler, will settle on the shelves. The

page_text: perforated shelves are arranged so as to admit of their being removed from
the vessel in order that the matters deposited thereon may be removed. The
steam generated by the superheated steam passes from the upper part of the
vessel by a steam pipe into the steam chest of the boiler, and any impurities
which might otherwise be carried over by the steam are arrested by means of
finely perforated partitions across the steam pipe. The heated and purified
water which descends to the bottom of the vessel passes into the boiler by a
water pipe which descends to near the bottom of the boiler, and in which
water pipe is inserted a filter. The superheated steam may be derived from
any source so long as it is introduced at a pressure commensurate with that
in the boiler, but it is preferred that the superheated steam should be derived
from the boiler by means of a steam pipe from the boiler being connected
with a suitable superheating apparatus (either heated by the same fire as
the boiler or otherwise) and the vessel above described.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Louis Emile Constant Martin in the Great Seal
Patent Office on the 7th July 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LOVIS
EMILE CONSTANT MARTIN, of No. 32, Albion Street, Hyde Park, in the
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of January, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Louis Emile Constant Martin, Her special licence
that I, the said Louis Emile Constant Martin, my executors, adminis-
trators, and assigns, or such others as I, the said Louis Emile Constant
Martin, 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 SUPPLYING WATER TO STEAM BOILERS," upon the condition
(amongst others) that I, the said Louis Emile Constant Martin, 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

page_text: 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 Louis Emile Constant Martin, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say:
This Invention has for its object improvements in apparatus for supplying
water to steam boilers. For these purposes the water which is to be sup-
plied to a steam boiler is caused first to pass in a highly divided state in the
form of rain or numerous small streams into a vessel, wherein are placed
perforated shelves, either in horizontal or inclined positions. Superheated
steam at the pressure of the steam in the boiler is caused continually to enter
at the lower part of this vessel, so as to meet and mix with the descending
drops or streams of water, by which the water will be highly heated, and some
part thereof evaporated, whilst the impurities which would incrust and settle
on the boiler, if the water he supplied directly to the boiler, will settle on the
shelves. The perforated shelves are arranged so as to admit of their being
removed from the vessel in order that the matters deposited thereon may be
removed. The steam generated by the superheated steam passes from the upper
part of the vessel by a steam pipe into the steam chest of the boiler, and any
impurities which might otherwise be carried over by the steam are arrested by
means of finely perforated partitions across the steam pipe. The heated and
purified water which descends to the bottom of the vessel passes into the boiler
by a water pipe, which descends to near the bottom of the boiler,and in which
water pipe is inserted a filter. The superheated steam may be derived from
any source so long as it is introduced at a pressure commensurate with that
in the boiler, but it is preferred that the superheated steam should be derived
from the boiler by means of a steam pipe from the boiler being connected
with a suitable superheating apparatus (either heated by the same fire as the
boiler or otherwise) and the vessel above described.
Having thus stated the nature of my Invention, I will proceed more fully
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side view of apparatus suitably arranged and combined
for carrying out my Invention; Figure 2 shows a vertical section thereof;
Figure 3 shows part of a plan thereof; and Figure 4 shows a horizontal

page_text: section thereof. In each of these Figures the same letters are used to indicate
the same parts.
A, A, is a vessel into which the water to be purified is received; the water
is introduced by the pipe B into the pipe C, across which are perforated
partitions C and C" of perforated metal. The water passes into the upper
part of the vessel A, and is divided into numerous streams by the perforated
diaphragın or plate C. The streams of water descend on to the horizontal
perforated tray D, and thence on to the inclined perforated shelves or
trays D', and thence through the perforated partition E at the bottom of the
vessel A, where the superheated steam is introduced by the pipe E. The
water which descends to the bottom of the vessel A is conveyed away by the
pipe F to a suitable receiver, from which it is pumped to the steam boiler.
The steam generated by the superheated steam passes away through the
perforated plate H, and is conveyed by the pipe G to the steam boiler at K.
In the arrangement shown in the Drawings it will be understood that the
pipes E receives steam from a superheating apparatus supplied from the
steam boiler, to which the steam generated in the vessel A is conducted by
the pipe G. It is preferred that the superheating apparatus should be heated
by the waste heat passing from the steam boiler furnace or furnaces as is
well understood when superheating steam in its passage from a steam boiler
to an engine. The perforated shelves or trays are arranged in a cylinder, and
are combined by a bolt which is passed through the series. This bolt has an
eye at the upper end by which the whole system can be raised out of the
vessel A to be cleansed. The supply of water to the vessel A will be regulated
by a cock or valve in such manner as not to produce injurious condensation
of the superheated steam, and according to the requirement of the steam
boiler to which the vessel A is applied. It will be evident that the vessel A
will at all times be supplied with superheated steam at a pressure of the
steain in the steam boiler, with which it is combined, and to which the steam
generated in the vessel A is conducted. The water passing off from the
vessel A by the pipe F' will be pure or in a comparatively pure state by reason
of its having deposited its salts or impurities on the shelves or trays D'. The
purifying apparatus may be used in any convenient position, and when
necessary a screw or other propeller or pump may be employed to insure
the requisite supply of superheated steam thereto.
Although it is preferred that the purifying apparatus should be supplied
with superheated steam from the steam boiler, to which it is applied, and to
which the steam generated in the vessel A is conducted, this is not essential,
as the superheated steam employed may be generated in another steam boiler

page_text: and be conducted through a superheating apparatus, and thence to the
vessel A to act therein on the water supplied thereto; and if the steam so
used is not generated at a pressure suitable to supply the vessel A with
superheated steam, at the requisite pressure, a pump or propeller may be
used to keep up the circulation and compress the steam, and to cause it to
pass into the vessel A, so as to maintain the requisite pressure therein.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I make no claim to
any of the mechanical parts separately; but what I claim is the combined
arrangements of apparatus herein described for supplying steam boilers
with purified water.
In witness whereof, I, the said Louis Emile Constant Martin, have
hereunto set my hand and seal. the Sixth day of July, in the year
of our Lord One thousand eight hundred and sixty-four.
EMILE MARTIN. (L.s.)
