Improvements in Apparatus for Heating and Purifying Feed Water
for Steam Boilers.
We THE MONITOR WATER PURIFIER COMPANY of 928 F Street North West
Washington District of Columbia United States of America Manufacturers and
CHARLES HENRY SNYDER of the same place Steam Engineer do hereby
declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
The said invention relates to improvements in that class of apparatus for heating
and purifying the water feed to boilers, in which the exhaust steam from an
engine is utilized as the heating agent and all oil and grease is separated from the
steam before it comes in contact with the water to be heated.
In the accompanying drawing:
Fig. 1, is an elevation, partly in section, of the improved apparatus complete.
Fig. 2, is a vertical section of the oil and grease separator.
Fig. 3, is an end view of one of the plates of the said separator.
Fig. 4, is a detail plan view of the valve for controlling the feed water inlet.
Fig. 5, is a detail plan view of the plate which rests above the filtering material
and serves to retain the same in position, and:
Fig. 6, is a plan view of the sectional foraminated plate on which the filtering
material rests.
a,
and
Referring by letter to said drawing:-A, indicates the casing of the improved
apparatus. This casing is formed of any suitable material capable of withstanding
steam pressure, and at its lower end is arranged the filtered water chamber which
is provided with a water glass b, designed to indicate the height of the filtered
water, and a drain pipe c, having a cock d, and is designed to be connected by a
pipe e, with a boiler. Above this chamber a, placed upon suitable supports, is the
foraminated diaphragm f, which is designed to support the filtering material
is made in two sections h, as shown in Fig. 6, so as to permit of it being readily
removed through the opening normally covered by the door i, when the filter is to
be cleaned. The filtering material which may be any substance suitable to the
purpose, is as stated, placed on the diaphragm, and it is retained in position and
prevented from rising with the water by the suitably supported plate or diaphragmį,
which is preferably perforated in the manner better shown in Fig. 5, so as to permit
free passage of the water to the filtering material.
k, indicates a pan which is supported upon lugs or other suitable supports l, at
about the proportional distance illustrated above the plate j. This pan k, is
provided with a plurality of openings m, surrounded by walls n, which are almost
as high as the side walls p, of the pan and it is also provided with a central
opening 7, surrounded by a wall r, quite as high as the said walls p. By virtue of
this construction of pan, it will be readily seen that pockets o, are formed for the
reception of sediment, and that when water is fed into the pan, it will pass in a thin
film over the walls n, and r, and down through the openings m, q, while the sediment
and foreign matter in said water will settle to the bottom of the pockets s.
All
k¹, indicates a plurality of pans which are placed one above the other above the
pan k, and are similar to said pan k, except that they are provided with legs t.
of these pans k, k³, are removably placed in position, and it will therefore be seen
that when the cap plate n, of the casing is disconnected, said pans may be readily

removed so as to permit of them being easily cleansed. v, indicates the feed water
inlet pipe which communicates with the interior of the casing A, above the
pansk, k', as shown in Fig. 1. This pipe v, is provided with a valve w, which has
a stem, and to this stem is connected an army, which in turn is connected to a
lever fulcrumed at a'; the parts being so arranged that when said lever is raised,
the valve will be closed and the supply of water cut off. The lever z, is connected
by a rod b, with a float c', arranged in a cylinder d', and as said cylinder is
it will be seen
connected by a pipe or pipes e', with the filtered water chamber a,
that when the filtered water rises to a certain height, the valve m, will be closed
through the medium of the mechanism described and the feed of water to the filter
will be stopped until a portion of the water is drawn from the chamber a, when the
float c', will move downwardly and the valve w, will again be opened. In this way,
the feed of water to the filter is regulated and the filter is therefore given more
time and is better enabled to purify the water before it is fed to the boiler.
In order to heat and boil the water, we contemplate utilizing the exhaust steam
from an engine. This steam is ordinarily impregnated with grease and oil, and in
order to free the steam of the same, we provide the oil and grease separator B,
which has its opposite sides connected by pipes C, D, with an engine and the filter
casing A, respectively, and is provided with a glass E, to indicate the amount of oil
or grease collected in the separator, and with a drain-pipe F, having a cock G.
Said separator has the pipes C, D, entering its opposite sides as stated, and between
said pipes are arranged the foraminated plates H, which are designed to permit the
steam to pass from pipe C, to pipe D, and yet catch or gather the oil and grease
and permit the same to drip into the bottom of the separator. Said plates are
removably placed in the separator B, so that they can be removed and cleaned
when necessary, and in order to present a greater surface to the steam so as to
enable them to better gather the oil and grease, they are corrugated as better shown
in Figures 2, and 3. It will also be perceived that by reason of the plates H, being
corrugated, channels are formed which guide the collected oil directly to the
bottom of the casing and prevent it from spreading over the plates and interfering
with the operation thereof.
The pipe D, enters the casing A, above the filtering material, as shown, and it
will therefore be seen that the steam and water will be thoroughly commingled in
the space above the filtering material and in the pans k, k, and in consequence the
water will not only be heated, which is obviously desirable, but will be boiled which
is also desirable, since it facilitates the separation of foreign matter from the water.
The exhaust steam after passing through the water and commingling therewith,
passes out of the casing A, through the pipe T, as shown in Fig. 1.
When the improved apparatus is employed, it will be observed that the water
will be fed to the boiler in a purified and heated state, and it will therefore be seen
that it is necessary to consume but a comparatively small amount of fuel to generate
steam and that no incrustations will form on the boiler and therefore the boiler will
last much longer and will be much more efficient than a boiler into which water is
1ed direct from a source of supply.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
The water heating and purifying apparatus described, comprising the filter having
the casing and a filtered water chamber at its bottom, a pan arranged above
the water chamber and having openings in its bottom surrounded by walls of less
hight than its side wall, a body of filtering material arranged between the pan and
filtered water chamber, a discharge pipe connected with said chamber, a water
induction pipe communicating with the interior of the casing above the pan, a
discharge pipe for steam communicating with the casing above the pan, a valve
arranged in the water induction pipe, the lever, connected with said valve, the
cylinder d', connected with the filtered water chamber, a float arranged in said

page_text: cylinder and carried by a rod connected to the lever, and the oil separator having
the casing provided with an opening in one side for connection with a source of
steam supply, and a discharge opening in its opposite side connected by a pipe with
the filter casing at a point between the filtering material and the pau, and the
plurality of foraminated plates disposed within the casing between the openings
thereof and provided with a series of vertical corrugations, substantially as
specified.
