1, STEPHEN WOOD UNDERHILL, a citizen of the United States, residing at
Croton-on-Hudson, in the County of Westchester, and State of New York,
United States of America, Farmer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to heat conservers and accumulators designed for use in
the escape flue or pipe of a heat generator, and the object thereof is to provide a
device for this purpose which is adapted to be placed in the flue or pipe of a stove,
furnace or other heat generator, and which is provided with a plurality of vertical
passages or spaces, through which the escaping products of combustion pass, said
device being also provided with means by which said passages or spaces may be
cleaned when desired, a further object being to provide a device of this class which
is designed to be placed in a casing which is larger than the flue or pipe, and which
is so constructed and arranged that the heat will be stored or accumulated therein,
and between the same, and the heat generator or stove or furnace, the construction
of the device being such that the smoke and other gaseous products of combustion
will pass freely therethrough, while the heat will be stored or accumulated therein,
or in that part of the flue or pipe between the device and the stove or furnace and
also within said stove or furnace. The invention is fully disclosed. in the following
specification. A section of an escape pipe or flue for the products of combustion
is preferably enlarged centrally thereof, and placed therein, are a plurality of
transverse horizontal bars, which are arranged at a predetermined distance apart,
and which are separated by spaces which are a little greater in width than said
bars. I also provide a shaft which passes transversely through the flue or casing
and centrally thereof, said shaft being arranged directly over the rods or bars
which are adapted to pass through the spaces between the rods or bars and by
turning the shaft from side to side by means of the handle, at one end thereof, the
rods or bars which are secured to the shaft will be caused to pass through the.
spaces between the rods or bars and thus said spaces and said rods or bars will be
kept clean of all deposits in the form of carbon or other substances. And in form
I
the flue or pipe or casing, is preferably rectangular in cross section or
employ a casing of this form, which is set into the flue or pipe, and said flue or
pipe is provided with a plurality of cross bars, which are preferably in the form of
vertical plates which may be of any desired width, and I also provide a cleaner
which consists of a cross head which is provided with a plurality of pins or rods,
which fit between the bars or plates and which are free to slide between said bars
or plates and the cross head is provided centrally with a shaft or rod which
extends through the flue pipe or casing and is provided with a handle and by
operating said cross head or moving it back and forth, over the rods or bars the
spaces between said rods or bars will be thoroughly cleaned as will be readily
understood. I employ a similar casing which is rectangular in form, and which is
adapted to be placed in the escape pipe or flue, and in the opposite sides thereof,
I form transverse oblong openings and in this form of construction I provide a
conserver which consists of a transverse head having rods or bars connected
therewith, any desired number of which may be employed, and said rods or bars
are adapted to be passed through the openings and the cross head is provided with
may

formed are vertical pins or rods which pass between the rods or bars, and in this
form of construction, two or more of these sliding or movable conservers or
accumulators are employed, and the arrangement is such that the rods or bars of
one are arranged directly over those of the other, and by means of this construction
the passage through the casing or through the pipe or flue is divided, and it will be
apparent that a great number of these sliding regulators may be employed, and
the construction may be duplicated in the same manner and in each of these forms
of construction the casing or that part of the pipe or flue, in which the conserver
and accumulator are placed, is preferably much larger than the rest of said flue or
pipe, and the object of this construction is to retard the passage of the heat through
the flue or pipe and to conserve the same and retain it in or below the casing in
which the conserver is placed. My improved device for storing and accumulating
heat, or that form thereof, is intended to be closed at all times, when the heating
apparatus, with which it is connected is in full operation, and only open for the
purpose of allowing a perfectly free escape of gases, of combustion, when the fire
is started, and when the fire is well established, it is again closed and the
arrangement thereof is such that when fully closed there will be sufficient space
therethrough, to allow of the escape of the smoke and gases, without interfering
with the necessary amount of combustion within the heater or other apparatus.

Improvements in Heat Storing Apparatus.
I, STEPHEN WOOD UNDERHILL, residing at No. 299 Church Street, Pough
keepsie, in the County of Dutchess, and State of New York, United States
of America, late of Croton-on-Hudson, Westchester, New York, Farmer, 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 :-
This invention relates to heat conservers and accumulators designed for use in
the escape flue or pipe of a heat generator, and the object thereof, is to provide a
device for this purpose which is adapted to be placed in the flue or pipe of a stove,
furnace or other Leat generator, and which is provided with a plurality of vertical
passages or spaces, through which the escaping products of combustion pass, said
device being also provided with means by which said. passages or spaces may be
cleaned when desired, a further object being to provide a device of this class
which, is designed to be placed in the casing which is larger than the flue or pipe,
and which is so constructed and arranged, that the heat will be stored or
accumulated therein, and between the same, and the heat generator, or stove or
furnace, the construction of the device being such that the smoke and other
gaseous products of combustion will pass freely therethrough, while the heat will
be stored or accumulated therein, or in that part of the flue or pipe between the
device, and the stove or furnace, and also within said stove or furnace.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which :-
Fig. 1, is a sectional side view of a section of the pipe or flue provided with my
improved heat conserver or accumulator.
Fig. 2, a section of that part of the casing or flue in which the accumulator is
mounted on the line 2, 2 of Fig. 1.

Fig. 4, a transverse vertical section thereof, on the line 4, 4;
Fig. 5, a plan view of another modification, and,
Fig. 6, a section on the line 6, 6.
In the drawing forming part of this specification reference being made to Figs. 1
and 2, I have shown at 7, a section of an escape pipe or flue for the products of
combustion, and said section is preferably enlarged centrally thereof, and placed.
therein, are a plurality of transverse horizontal bars 8, which are arranged at a,
predetermined distance apart, and which are separated by spaces 9, which are a little
greater in width than said bars 8..
I also provide a shaft 10, which passes transversely through the flue or casing 7,
and centrally thereof, said shaft being arranged directly over the rols or bars 8,
and being provided at each side with similar rods or birs il, which are adapted
to pass through the spaces 9, between the rods or bars 8, and by taraing the
shaft 10, from side to side, by means of the handle 12, at one end thereof;
the rods or bars 11, which are securel to the shaft 10, will be caused to pass
through the spaces 9, between the rods or bars 8 and thus said spaces and said
rods or bars will be kept clean of all deposits in the form of carbon or other
substance.
In Figs. 3 and 4, I have shown a modification of this construction, and in this
form the flue pipe or casing 7, is preferably rectangular in cross section or I may
employ a casing of this form, which is set into the flue or pipe, and said flu or
pipe is provided with a plurality of cross bars 8, which are preferably in the form
of vertical plates, which may be of any desired width, and I also provide a cleaner
which consists of a cross head 14, which is provided with a plurality of pins or
rods 15 which fits between the bars or plates 8 and which are free to slide between
said bars or plates and the cross head 14 is provided centrally with a shaft or
rod 16 which extends through the flue pipe or casing 7 and is provided with a
handle 17, and by operating said cross head or moving it back and forth, over the
rods or bars 8, the spaces between said rods or bars will be thoroughly cleaned
as will be readily understood.
In the construction shown in Figs. 5 and 6, I employ a similar casing 7, which
is rectangular in form and which is adapted to be placed in the escape pipe or flue
and in the opposite sides thereof, I form transverse oblong openings 18, and in this
form of construction I provide a conserver which consists of a transverse head 19,
having rods er bars 20, connected therewith any desired number of which inay be
employed, and said rods or hars are adapted to be passed through the opening 18,
and the cross head 19 is provided with a handle 21 and mounted in the casing 7, or
the side thereof, in which the opening 18 is formed are vertical pins or rods 22,
which pass between the rods or bars 20, of the conserver, and in order to clean
said rods or bars, it is only necessary to pull out the cross head 18, aud with the
rods or bars 20, and in this form of construction, two or more of these sliding or
movable conservers or accumulators are employed, and the arrangement is such,
that the rods or bars 20, of one are arranged directly over those of the other, and.
by means of this construction the passage through the casing 7, or through the pipa
is divided as shown in Fig. 5 and it will be apparent that a greater number of
these sliding regulators may be employed, and the construction shown in Figs. 3
and 4, may be duplicated in the same manner as shown in Figs. 5 and 6, and in
each of these forms of construction, the casing 7, or that part of the pipe or flue
in which the conserver and accumulator are placed, is preferably much larger
than the rest of said flue or pipe, and the object of this construction is to retard
the passage of the heat through the flue or pipe, and to conserve the same and
retain it in or below the casing in which the conserver is placed.
My improved device for storing and accumulating heat or that form thereof,
shown in Figs. 1 and 2, and 5 and 6, is intended to be closed at all times, when the
heating apparatus with which it is connected is in full operation, and ouly open for
the purpose of allowing a perfectly free escape of the gases of combustion

page_text: when the fire is started, and when the fire is well establishel, it is again
closed, and the arrangement thereof, is such that when fully closed there will
be sufficient space therethrough, to allow of the escape of the smoke anal gases,
without interfering with the necessary amount of combustion within the heater or
other apparatus..
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. The herein described heat accumulator and conserver, which is adapted to be
connected with the escape pipe or flue of a heat generator, said device being
constructed as herein described and as shown in the drawing.
2. An escape pipe or flue for a furnace or other heat generator, providel with a
heat accumulator and storer, which is placed therein, and which is provided with
a plurality of vertical passages or spaces, through which products of combustion
pass, and with means for cleaning said passages or spaces, said device being designed
to allow of the free passage of the smoke, and the gaseous products of combustion,
and to accumulate and store the heat therein, and between the same and the
heat generator, substantially as shown and described.
3. An escape pipe or flue for a furnace or other heat generator, provided with a
heat accumulator, and storer, which is placed therein, and which is provided with
a plurality of vertical passages or spaces, through which the products of combustion
pass, and with means for cleaning said passages or spaces, said device being designed
to allow of the free passages of the smoke, and the gaseous products of combustion,
and to accumulate and store the heat therein, and between the same and the heat
generator, and the pipe or flue where said device is placed, being larger than the
other portions thereof, substantially as shown and described.
4. A heat generator and storer for the escape flue or pipe of a heat generator,
which consists of a plurality of transverse bars between which are formed spaces, of
predetermined width, and a shaft mounted transversely of said shaft and provided at
its opposite sides with parallel rods or bars, which are adapted to pass through said
spaces, between said parallel stationary rods or bars, when the shaft is turned,
substantially as shown and described.
