PROVISIONAL SPECIFICATION.
I, JACOB STRUBEN a citizen of the United States, residing at the City of
Kalamazoo, State of Michigan, United States of America, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
:-
My invention relates to improvements in internal feed-water heaters and purifiers
for use in steam boilers.
It has long been known that when water is first heated in a boiler is the time.
when the lime and other incrusting material are deposited. It is necessary,
however, that the water be thorougbly heated to secure a complete deposit.
Numerous devices have been produced for accomplishing this desired result, which.
have been more or less successful. In all of these after the deposit has been made
it has been necessary to clean the parts inside the boiler, and so far as is known to
me no means has ever been provided for making that deposit complete before the
water comes in contact with the tubes and more or less of the deposit has been
distributed over the entire interior of the boiler.
The objects of my invention are therefore, first, to provide an internal feed-water
heater and purifier for boilers which can be easily removed from the boiler to be
cleaned; second, to provide an internal feed water heater and purifier in which the
water shall be thoroughly heated and all incrusting material deposited before it
passes to the boiler below, and other objects appearing definitely in the detailed
description.
I accomplish these objects of my invention by the devices and means described in
the following specification.-
Within the boiler and resting upon the boiler tubes, are two little bases of cast
iron. On these is supported my improved feed-water heater and purifier, which is
made up of two sections. One of the sections has a receptacle toward one end.
A delivery pipe extends down to near the bottom of this receptacle. An over-
flow spout, projects out from near the top of the same into the remaining portion
of the section, which is formed like a trough, with dividing-partitions extending
alternately from opposite sides to form a long continuous passage. A spout is at
the opposite end of the passage leading into the other section, which is of similar
construction. Short partitions extend between the partitions, and reach nearly to
the top of the water level between the partitions, and serve to retard the flow of
water and secure a precipitation of all incrusting materials within it. At intervals
the manhole of the boiler is opened and the sections are withdrawn from the boiler
and the incrusting material removed. All of the coarser material will be found
deposited in the troughs of the sections above described.

page_text: The device will work without the partitions but will be better with them. It
could of course be made of one section where the boilers are small. Where the
boilers are very large, it will be necessary to make the same of more than two
sections. In that case the receptacle should be a separate part. It should then
project down to the boiler tubes to heat the water as rapidly as possible. The
bases are not an absolute necessity, but serve to hold as purifier-sections above the
tubes in the steam. In use it will be found that most of the water will be
evaporated from the purifier and heater before it reaches the end of the tortuous
passage or troughs and that very little of it will flow out at the depressions. This
secures complete precipitation of the incrusting material. In use it will be found
this device practically relieves all back pressure of the pump. The device is also
of great advantage when water accidentally becomes low in the boiler, because it
will allow it to enter on the purifier and become gradually heated before it strikes
the superheated portions of the boiler. This it will be readily understood avoids
much of the danger of explosions.
Having thus described iny improved feed water heater and purifier, I desire to
state that from my above description it will be noted that it is capable of great
variation in its details without departing from my invention.

I, JACOB, STRUBEN, a citizen of the United States, residing at the City of
Kalamazoo, State of Michigan, United States of America, Manufacturer, 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:
.
My invention relates to improvements in internal feed-water heaters and purifiers
for use in steam boilers.
It has long been known that when water is first heated in a boiler is the time
when the lime and other incrusting material are deposited.
It is necessary,
however, that the water be thoroughly heated to secure a complete deposit.
Numerous devices have been produced for accomplishing this desired result, which
have been more or less successful. In all of these after the deposit has been made,
it has been necessary to clean the parts inside the boiler, and so far as is known to
me no means has ever been provided for making that deposit complete before the
water comes in contact with the tubes and more or less of the deposit has been
distributed over the entire interior of the boiler.
The objects of my invention are therefore, first, to provide an internal feed-water
heater and purifier for boilers which can be easily removed from the boiler to be
cleaned; second, to provide an internal feed water heater and purifier in which
the water shall be thoroughly heated and all incrusting material deposited before
it passes to the boiler below, and other objects appearing definitely in the detailed
description.
I accomplish these objects of my invention by the devices and means described
in the following specification and illustrated in the accompanying drawings, in
which,
Figure 1 is a side elevation of a horizontal boiler containing one of my improved
internal feed-water heaters and purifiers, portions being broken away to show
details of construction and the relative position of parts;

page_text: Figure 2 is an enlarged detail perspective view of my improved internall
feed-water heater and purifier shown resting upon the tubes of the boiler;
Figure 3 is a detail view of a slight modification.
Similar letters of reference refer to similar parts throughout the several views.
Referring to the lettered parts of the drawing, A represents the boiler, A' the-
boiler tubes within, A" the manhole. Within the boiler and resting upon the
tubes A' are two little bases H H of cast iron. On these is supported my improved
feed-water heater and purifier, which is made up of two sections B and B. The
section B has a receptacle C toward one end. The delivery pipe D extends down:
to near the bottom of this receptacle C. An overflow spout C projects out from
near the top of the same into the remaining portion of the section, which is formed.
like a trough, with dividing partitions extending alternately from opposite sides to
form a long continuous passage. A spout F is at the opposite end of the passage
leading into the section B' which is of similar construction. Short partitions E" En
extend between the partitions E' and reach nearly to the top of the water level.
between the partitions, and serve to retard the flow of water and secure a.
precipitation of all incrusting materials within it. At intervals the manhole of the
boiler is opened and the sections B B are withdrawn from the boiler and the
incrusting material removed. All of the coarser material will be found deposite·1.
in the troughs of the sections above described.
The device will work without the partitions E", but will be better with them..
Where the
It could of course be made of one section where the boilers are small.
boilers are very large, it will be necessary to make the same of more than two-
sections. In that case the receptacle C should be a separate part as indicated in
Figure 3. It should then project down to the boiler tubes to heat the water as
rapidly as possible. The bases H are not an absolute necessity, but serve to hold
as purifier-sections above the tubes in the steam. In use it will be found that most.
of the water will be evaporated from the purifier and heater before it reaches th>
end of the tortuous passage or troughs and that very little of it will flow out
at the depressions F. This secures complete precipitation of the incrusting
material. In use it will be found this device practically relieves all back
pressure of the pump. The device is also of great advantage when water acci-
dentally becomes low in the boiler, because it will allow it to enter on the purifier
and become gradually heated before it strikes the superheated portions of the
boiler. This it will be readily understood avoids much of the danger of
explosions.
Having thus described my improved feed water heater and purifier, I desire to
state that from my above description it will be noted that it is capable of great
variation in its details without departing from my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In an internal feed-water heater, the combination of the bases H H to rest
upon the tubes of the boiler; the sections or trays B B', formed into a long.
continuous trough by the partitions E' E'; sub-partitions E" E" extending between
the partitions E to retard the passage of the water through the troughs ;.
a receptacle C to form a connection therewith with a delivery pipe from toward
the top thereof and a supply pipe D, leading down toward the bottom of the
receptacle, all co-acting substantially as described for the purpose specified.
.
2. In an internal feed water heater, the combination of the sections B B₁ formed.
into a long continuous trough by the partitions E E¹; subpartitions E" E",
extending between the partitions E', to retard the passage of the water through
the troughs; a receptacle C, to form a connection therewith with a delivery
pipe from toward the top thereof and a supply pipe D, leading down toward the
bottom of the receptacle all coacting substantially as described for the purpose
specified.

page_text: 3. An internal feed-water beater consisting of a box like casing with alternate
partitions extending from opposite sides nearly across the same to form a tortuous
trough like passage, subpartitions between the alternate partitions of lesser height
to retard the passage of the water in combination with a supply pipe delivering the
feed-water into one end of the same to allow it to pass through the passage to
become thoroughly heated as specified.
4. In an internal feed-water heater, the combination of a receptacle; a supply
pipe leading toward the bottom of the receptacle; an overflow-passage from the
receptacle and a casing with a tortuous passage into which the receptacle delivers
the water, coacting as specified.
