page_text: I, THOMAS JUDSON WHITNEY, 45, North Second Street, of the City of Phila-
delphia, County of Philadelphia, and State of Pennsylvania, U.S.A., Manufac-
turer, do hereby declare the nature of this invention to be as follows:-
My invention relates to a steam boiler feeder, wherein I employ an auxilliary
boiler and use an exterior auxilliary or supplemental casing, which surrounds
the interior boiler or heater and keeps the contents thereof constantly heated to
the requisite degree, said internal boiler being heated by means of exhaust
steam within said casing, and provision being made by means of pipes and a
suitable valve or valves for regulating the circulation between the main and
supplemental boiler or heater.
It also consists of an improved construction of supplemental boiler and its
adjuncts, as well as of novel details of construction which will now be set forth.
In the drawings, Figure 1 represents a side elevation of a steam boiler feeder
embodying my invention, the auxilliary or supplemental boiler being shown in
section. Figure 2 represents a front view of my improved form of valve.
Figure 3 represents a view of the lower part of the valve body. Figure 4

the disk valve. Figure 6 side view of the stem for operating the disk valve.
Figure 7 horizontal section of a modified form of valve, and Figure 8 side view
of valve and lever.
Referring to the drawings herein, 1 represents a main steam boiler and 2
supplemental boiler or feed water heater, located above said main boiler, said
supplemental boiler consisting of an outer shell or casing 3 within which is
connected with the feed water heater 4, it being noticed that the latter is pre-
ferably located therein so that the forward end of the heater is near the lower
side of the outer casing, and the rear end near the upper side of the adjacent
portion or shell of the casing 3. wherein a chamber or receptacle 5 is formed
entirely around the heater 4 for the reception of a body of hot water, as will
be hereinafter explained. The object of thus disposing the heater 4 is to pro-
vide a positive and efficient means for draining the heater and inducing the
flow of water therefrom, and the elevation of the rear end of the heater also
gives an additional height or head for the water. F indicates a steam inlet pipe
which leads into the upper portion of the space between the heater 4 and the
casing 3, whereby exhaust steam may be conducted thereinto, said steam leaving
the casing through the pipe G and being conducted to any desired point.
D designates an inlet pipe for the feed water, the same entering the casing 6
through the passage 7 and chamber S, and passing, when the valve is in the
proper position, through the port 9 of the rotating slide or disk valve 10 into
After the
the chamber 11 and pipe E to the upper portion of the heater 4.
heater is filled to the desired extent the disk-valve is turned in the direction

page_text: of the arrow 13 so that the port 9 of the valve 10 forms a communication
between the chambers 11 and 14, whereupon it will be seen that the water which
has in the meantime been heated to a high degree in the heater 4, flows from
the lower portion of said heater through the pipe B into the chamber 15 of the
valve and thence through the port 16 of the valve 10 into the chamber 17 and
pipe C, into the lower portion of the main steam boiler 1. The steam contained
in the upper portion of the main steam boiler 1, flows therefrom through the
pipe A, chamber 14, port 9 and chamber 11, into the pipe E and thence to the
heater 4.
It will be observed that the head of the outer shell 3, has a flanged head 18,
to which is secured the shell of the heater 4; and in the head 19 of this inner
shell is attached the pipes for feeding and discharging the same. I do not, how-
ever, confine myself to this particular manner of making these shells.
The special manner of constructing the valve, as shown in Figs. 2, 3, and 4,
represents only one of the various forms used by me in carrying out my inven- .
tion in a practical form. In this instance I form the valve-body of two parts,
the base portion 20 having five chambers, 8, 11, 14, 15, and 17, respectively,
with a radial pipe connection communicating with each chamber. The upper
portion 21 is crowned to provide a chamber within which is placed a disk
valve 10, having two oppositely disposed concentrically formed chambers, or
ports 9, 16, on the under side, and midway between these ports, on the upper
side of the disk, are notched ribs 22. The upper end of a stem 23 passes
through a suitable packing box in the crowned part 21 of the valve, and a
lever 24 is attached thereto, and is bent downwardly to the flat portion of the
valve body, and then extended out on a plane with the valve disk and pro-
vided with a handle. A lug 25 projects down past the flat body of the valve
casing, and suitable stops 26 are formed on the casing to limit the movement
of the lever 24. The stem 23 has at its lower end cross arms 27, which rest in
the notched ribs 22, when in position, so that when the stem is turned the disk
turns therewith.
In Fig. I show a plug-valve arrangement which substantially does the work
as well as the other form of valve just described, but I find it is a more difficult
valve to keep in repair, and I merely show this view to illustrate the manner of
construction.
It will be apparent from the foregoing that the water in the heater 4 will
always be in a heated condition by reason of the shell being in contact with
the exhaust steam contained in the chamber 3, and by securing the heater
within its casing in the manner specified, a body of hot water is retained
adjacent to the sides and end of the heater 4, which also assists in heating the
latter.
When the disk valve is so turned that the disk port 9 forms communication
between the chambers 11 and 14, and the port 16, with the chambers 15, 17,
the water in the lower portion of the heater passes by gravity to the main steam
boiler through the pipe B, valve 6 and pipe C to the steam boiler 1, this move-
ment being continued until the main steam boiler has received the requisite
amount of water. It will be observed that when the lever 24 is turned to a
vertical position, so that it is located at the star, Fig. 2, all the ports are closed.
It is well known that the deposit or sediment in water if allowed to enter a
steam boiler and come directly in contact with the fire surfaces is converted into
what is generally known as scale, this action taking place particularly when
the water is heated to a high temperature, but by my present improvement the
feed water is conducted from the heater 4, a few inches from the bottom thereof,
and since the steam pressure in the boiler is the same as in the main boiler, the
deposits or sediment in the water are precipitated and remain in the heater in
a granulated form, and are easily blown out by steam pressure, and not allowed
to enter the main steam boiler, as the blow-off cock H communicates with the
interior of the heater as shown at 26. By thus keeping the main boiler clean

page_text: and free from scale and sediment the safety and durability thereof are greatly
increased. A suitable blow-off cock X is also provided in the head 18 for the
outer casing.

I, THOMAS JUDSON WHITNEY, of 45, North 2d Street, City and County of
Philadelphia, State of Pennsylvania, U.S.A., 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 a steam boiler feeder, wherein I employ an auxilliary
boiler and use an exterior auxilliary or supplemental casing, which surrounds
the internal boiler or heater, and keeps the contents thereof constantly heated to
the requisite degree, said internal boiler being heated by means of exhaust
steam within said casing, and provision being made by means of pipes and a
suitable valve or valves for regulating the circulation between the main and
supplemental boiler or heater. It also consists of an improved construction of
supplemental boiler and its adjuncts. It further consists of novel details of
construction, all as will be hereinafter fully set forth and particularly pointed
out in the claims.
Referring to the drawings accompanying my Provisional Specification,
Figure 1 represents a side elevation of a steam boiler feeder embodying my
invention, the auxilliary or supplemental boiler being shown in section. Figure 2
represents a front view of my improved form of valve. Figure 3 represents a
view of the lower part of the valve body. Figure 4 cross section of valve
through line of Fig. 3. Figure top view of the disk valve. Figure 6 side
view of the stem for operating the disk valve. Figure 7 horizontal section of
a modified form of valve; and Figure 8 side view of valve and lever.
1 represents a main boiler and 2 supplemental or feed water heater, located
above said main boiler consisting of an outer shell, or casing 3, within which
is contained the feed water heater 4, it being noticed that the latter is prefer-
ably located therein so that the forward end of the heater is near the lower side
of the outer casing, and the rear end near the upper side of the adjacent portion
of the shell or casing 3, wherein a chamber or receptacle 5 is formed entirely
around the heater 4 for the reception of a body of hot water, as will be
explained. The object of thus disposing of the heater 4 is to provide a posi-
tive and efficient means for draining the heater and inducing the flow of water
therefrom, and the elevation of the rear end of the heater also gives an addi-
tional height or head for the water. Findicates a steam inlet pipe which leads
into the upper portion of the space between the heater 4 and the casing 3
whereby exhaust steam may be conducted thereinto, said steam leaving the
casing through pipe G and being conducted to any desired point.
After
1) designates an inlet pipe for the feed water, the same entering the valve
casing through passage 7, and chamber 8, and passing, when the valve is in
the proper position, through the port 9 of the rotating slide or disk valve 10
into the chamber 11 and pipe E to the upper portion of the heater 4.
the heater 4 is filled to the desired extent the disk valve 10 is turned in the
direction of the arrow 13 so that the port 9 of the valve 10 forms a communi-
cation between the chambers 11 and 14, whereupon it will be seen that the

page_text: water which has in the mean time been heated to a high degree in the heater 4
flows from the lower portion of the said heater through the pipe B into the
chamber 15 of the valve and thence through the port 16 of the valve 10 into the
chamber 17 and pipe C, into the lower portion of the main steam boiler 1, and
steam flows therefrom through the pipe A, chamber 14, port 9 and chamber 11
into the pipe E and thence to the heater 4.
It will be observed that the head of the outer shell 3 has a flanged head 18,
to which is secured the shell of the heater 4; and in the head 19 of this inner
shell is attached the pipes for feeding and discharging the same.
The special manner of constructing the valve, as shown in Figs. 2, 3 and 4,
represents only one of the various forms used by me. In this instance I form
the valve body of two parts, the base portion 20 having five chambers 8, 11, 14,
15 and 17 respectively, with a radial pipe connection communicating with each
chamber. The upper portion 21 is crowned to provide a chamber within which
is placed a disk valve 10, having two oppositely disposed, concentrically-formed
chambers, or ports 9, 16, on the under side, and midway between these ports, on
the upper side of the disk are notched ribs 22. The upper end of a stem 23
passes through a suitable packing box in the crowned part of the valve, and a
lever 24 is attached thereto and is bent downwardly as the flat portion of the
valve body, and then extended out on a plane with the valve disk and provided
with a handle. A lug 25 projects down past the flat body of the valve casing,
and suitable stops 26 are formed on the casing to limit the movement of the
lever 24. The stem 23 has at its lower end cross arms 27, which rest in the
notched rib 22, when in position, so that when the stem is turned the disk turns
therewith.
In Fig. 7 I show a plug valve arrangement which substantially does the work
as well as the other form of valve, but it is a more difficult valve to keep in
order.
It will be apparent that the water in the heater 4 will always be in a heated
condition by reason of the shell being in contact with the exhaust steam con-
tained in the chamber 3, and by securing the heater within its casing in the
manner specified a body of hot water is retained adjacent to the sides and end
of the heater 4, which also assists in heating the latter.
When the disk valve is so turned that the port 9 forms communication
between the chambers 11 14, and the port 16 with the chambers 15 17, the water
in the lower portion of the heater passes by gravity to the main steam boiler
through the pipe B, valve 6 and pipe C to the steam boiler 1, this movement
being continued until the main steam boiler has received the requisite amount
of water. When the lever 24 is turned to a vertical position, so that it is
located at the star, Fig. 2, all the ports are closed.
It is well known that the deposit or sediment in water if allowed to enter a
steam boiler and come directly in contact with the fire surface is converted into
what is generally known as scale, this action especially taking place when the
water is heated to a high temperature, but by my improvement herein the feed
water is conducted rom the heater 4, a few inches from the bottom thereof, and
since the steam pressure is the same as that in the main boiler, the deposits
or sediment in the water are precipitated and remain in the heater in a granu-
lated form, and are easily blown out by steam pressure, and not allowed to enter
the main steam boiler, as the blow-off cock H communicates with the interior
of the heater as shown at 26. By thus keeping the main boiler clean and free
from scale and sediment, the safety and durability thereof are greatly increased.
A suitable blow-off cock X is also provided in the head 18 for the outer casing.
