Year: 1889

page_text: Date of Application, 23rd July, 1889-Accepted, 23rd July, 1890
I, JOHN DENNIS SULLIVAN of 314 Laurel Street, in the City of New Orleans, and
State of Louisiana, one of the United States of America, Mining Engineer, do hereby
declare the nature of my invention for IMPROVEMENT IN A FEED WATER HEATER,
CLEANER AND MINERAL SEPARATOR, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to an improvement in a feed water heater, cleaner, and
mineral separator, in which a filter placed within the boiler is made to filter the
water and separate the mineral, and the objects of my improvements are to provide
device whereby water may be filtered within the boiler. I attain these objects by
the mechanism illustrated in the accompanying drawings, in which-
Figure 1 is a side view partly in section.
Figure 2 is a front end view of boilers.
Figure 3a top view of perforated plate or filter.
Figure 4 is a top view of water trough, showing partitions and mineral
chambers.
Similar letters referring to similar parts throughout the several views:
In constructing my invention 1 form a U shape (in cross section) filtering compart-
ment say, one half the length of a boiler. Within this filtering compartment I place
two perforated plates which form upper and lower filtering plates. Between these
perforated plates i place coke, or other filtering material. I then construct a trough
as shown in figure 4, with partitions as shown by T, also mineral chambers constituting
depositing chambers or pockets (as shown by S) in the bottom of the trough R. When
the space between my perforated plates within filtering compartments bave been filled
with filtering material I then place my trough and filter within boiler by introducing
same through the man hole of boiler, and which is held in position by means of
stirrup J, at the end of the boiler I introduce my feed water pipe G, and carry same
forward within boiler until it comes in close proximity to blow off pipe M, which is
in a vertical position within boiler A, the feod water pipe is carried into my filtering
compartment or chamber, until it extends say one half the length of the filter
chamber B, running parallel with a perforated pipe 1, which is within chamber B,
said perforated pipe being attached to blow off pipe M.
C, shows coke within filtering compartment. D, is perforated plate. G. is a manifold
pipe which comes from feed pump. H. being branch pipes. L. is an end view of
cleaner or filter. . N. shows portion of flue of boiler. O, are holts or nuts on stirrups J.
K, is a water line within boiler. P and Q show position of perforated plates in cleaner
or filter chamber B. R, is an extension trough leading feed water back to mud
drum leg, showing deposit chambers S, & partitions T, which cause the water to tako
a sinuous course down the trough to the point of discharge U. The blow off pipe
has valves, and connections to discharge outside. Each branch pipe H, has stop
valves and check valves as shown.
In practice I admit water through feed pipe G which is carried midway within
cleaner or filter B, the feed water being confined within B, flows upwards through
coke or other filtering material, and percolates through perforated plate Q, and
after being cleaned or filtered is carried into feed water trough R, and as it flows
through said trough comes in contact with partitions, and should there be any
mineral left in water, said mineral is deposited in chambers S, and water flows into
boiler at the point of discharge U. The perforated pipe I, (shown in Fig. 1.) extends
ay nine feet, the entire length of cleaner or filter, and under lower perforated plate,
and all mud or sediment deposited under said plate is carried off by means of blow

page_text: off pipe F as water is partially evaporated as it passes through trough R, and the
water being filtered within the boiler, the deposit of sediment in the mud drum,
(if any) is small in comparison to the old method.
Having now particularly described and ascertained the nature of my said
invention, declare that what I claim as new and desire to secure by letters
patent is―
1-A feed water heater cleaner and purifier such as described, the combination of
a boiler with a filter placed therein, and the filtration of the water within the boiler,
said filtering chamber being adjusted within the boiler by means of stirrups for the
purpose set forth.
2-A feed water heater, cleaner and purifier such as described the combination of
a boiler with a filter placed therein, the filtration of the water within the boiler by
means of a filtering chamber placed therein the perforated pipe running under
filtering plate and connecting with blow off pipe F, for the purpose set forth.
3-A feed water heater, and purifier such as described, the combination of a boiler
with a filter placed therein, the filtration of the water within the boiler by means of
a filtering chamber placed therein, the feed water pipe leading under filtering
plate and connecting with perforated pipe attached to blow off pipe for the purposo
set forth.
4-A feed water heater, and purifier such as described, the combination of a boiler
with a filter placed therein, the filtration of the water within the boiler by means
of a filtering chamber placed therein, the feed water leading a sinuous course back to
mud-leg for the purpose set forth.
5-A feed water heater and purifier such as described, the combination of a boiler
with a filter placed therein, the filtration of the water within the boiler by means of
a filtering chamber placed therein, the water trough with partitions and mineral
chambers therein, for the purpose set forth.
