Improvements in Regulators for Hot Water Heating Apparatus.
WILLIAM GEIPEL and FREDERICK MONTAGUE. TOWNSHEND LANGE, of 68, Victoria
Street, Westminster, Engineers, do hereby declare the nature of this invention
to be as follows:-
This invention has reference to improvements in methods of automatically
egulating heating apparatus, such as is used for the heating of buildings etc.
by hot water, and has for object an improved and more reliable means of
maintaining an approximately constant temperature of the hot water, and a
reduction in the attention required by the fire, and an improved means of auto-
matically operating the dampers.
One method of carrying out our improvement consists of an arrangement of
two tubes made of metal having different coefficients of expansion fixed at one
end and free to move at the other so as to impart motion to a cord which operates
the usual door for admitting air either to the underside or top side of the fire
according as an increment or an arrest of the heating is required.
One tube 18 preferably of 11on, the other of brass, and in order to obtain the
maximum motion for the least difference of temperature, we arrange these two
tubes as the two sides of an 180scles triangle At the apex of the triangle 18
placed the connection for joining the two tubes together. The inlet and outlet
are at the fixed ends of the tubes, while either tube may be made the inlet oi
outlet, one being connected to the flow pipe or top of the boiler, the other being
connected to the return pipe or bottom of the boiler. There is thus a constant
circulation of water through the tubes, while the temperature thereof 18 raised
or lowered according to the temperatures of the water in the boiler When the
temperature rises the brass tube expands more than the non tube, thus impart-
ng motion to the apex of the triangle In order to multiply this motion there
18 a lever provided the short end being attached to oi pressing against the apex
the long end having attached to it a rod or cord for transmitting the motion to
the draught regulator or dampei
The point at which the draught regulator or damper closes or opens is adjusted
by the length of the above mentioned 1od or cord, and a convenient method of
adjusting this may be provided
In place of the rod or cord we may use a chain or flexible wire or any other
suitable means of transmitting the motion of the apex, and pulleys or cranks or
other means may be used for guiding the said rod or cord.
Generally we prefer to adjust the apparatus so that the admission of air to
the urderneath side of the fire is closed at about 200 degrees Fahrenheit to allow
a small margin before the boiling point 18 reached
We provide an automatic an cock or valve at the highest point of the tubes
to remove the au and ensure a full flow of water through them.
In another arrangement we make use of two 1ods of metals having different
coefficients of expansion fixed at one end and free to move at the other, the two
rods forming the two sides of an 180scles triangle. The said 1ods are enclosed

o otherwise so that the heat of the water is transmitted to the 1ods. The said
1ods at the apex of the triangle are connected to a rod which passes to the outside
of the case through a stufhing box The motion of this 1od is transmitted to
the dampers through levers or cords as already described, while part of the 5
levers may be enclosed in the said box or case it desed, though preferably the
whole of the motion increasing gear is placed outside of the box

WILLIAM GEIPEL, and FREDERICK MONTAGUE TOWNSHEND LANGE, Parliament
Mansions, in the City of Westminster, late of 68, Victoria Street, Westminster,
Electical and Mechanical Engineois, trading as Geipel and Lange, 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.-
1-
This invention has reference to improvements in the methods of automatically
1egulating heating apparatus, such as is used for the heating of buildings &c by
hot water, and has foi object an improved and more reliable means of maintaining
an approximately constant temperature of the hot water and a reduction in the
attention requned by the fire, and an improved means of automatically regulating
the dampers
For the purpose of describing the invention, we refer to the accompanying
diawings in which
Fig 1, is a front view showing the apparatus connected to a hot-water boiler,
and Fig. 2 18 a side view of the same Fig 318 a view showing the apparatus
fixed inside the shell of the boiler, and Fig 4 is a view showing the apparatus
fixed in a separate box
Our improvements as shown in Figs. 1 & 2 consist of an arrangement of two
tubes "A" and "B" Fig. 2 made of metals having different coefficients of
expansion, fixed at one end and free to move at the other so as to impart motion
to a cord C" Fig. 1 & 2 operating the damper D' Fig. 2 which iegulates
the quantity of an passing to the underside oi topside of the boiler, according
as an increment or an anest of the air is required.

"
The tube "A 18 preferably of biass and the tube "B" of uon, and in order
to obtain the maximum motion for the least difference of temperature, we airange
these two tubes as the two sides of an 180celes triangle as shown in Fig. 2
At the apex of the tangle is placed the connection for joining the two tubes
together as shown at "E" in Fig 2.
The inlet and outlet are at the fixed end of the tubes, while either tube may
be made the inlet or outlet, one being connected to the flow pipe
"F" Fig. 1
or to the top of the boiler, the other being connected to the return pipe "G"
Fig 1 & 2 o to the bottom of the boiler. There is thus a constant cuculation
of water through the tubes, while the temperature thereof 18 1aised or lowered
according to the temperature of the water in the boiler When the temperature
rises the biass tube "A" Fig. 2 expands more than the iron tube "B
imparting motion to the apex of the tangle.
thus

page_text: In order to multiply this motion, there is provided a lever "H" Fig. 1 & 2
the short end being attached to or pressing against the apex, the long end having
attached to it a 1od or cord "C" Fig. 1 & 2 for transmitting the motion to the
regulator on damper "10" Fig. 2.
The an regulator or damper may be of any of the well known kinds which
ale at present used for such purpose. The an regulator we prefer to use is that
known as the slotted cylinder type and the damper if used may be of the ordinary
swivel or hinged type and there may be one damper for closing
the an supply to the under side of the hie and another for letting the air in to
the top side of the fire, both of which may be worked by one thermostat of the
kind herein referred to.
The point at which the au regulator or damper closes or opens 18 adjusted by
the length of the above mentioned 1od or cord, a convenient method of adjusting
being thus provided In place of the rod or cold, we may use a chain, flexible
wire or any other suitable means of transmitting the motion of the apex, and
pulleys or cranks may be used for guiding the said 1od or cord.
Generally we prefer to adjust the apparatus so that the admission of air to
the undeneath side of the file is closed at about 200 Fahrenheit to allow a small
margin before the boiling point is reached.
It is not necessary in all cases that the damper "D" should let air into the
top side of the fine for in some cases we use the damper "D" simply to regulate
the quantity of air passing to the under side of the file
We provide in some cases a counter weight or spring, or a combination or
number of either to balance the level, and these may be also used in adjusting
the apparatus but are not essential.
We provide an automatic an cock J" Fig. 1 at the highest point of the
tubes to remove the air and ensure a full flow of water through them.
Another auangement of our invention is shown in Fig 3. In this we use the
same isosceles triangle "A" and "B" as before, but instead of the water cuculat-
ing through the tubes the latter are immersed in the water inside the boileı M,
and may either cousist of tubes 01 1ods At the base "L" of the triangle the
tubes or 1ods are hxed to the shell of the boiler, the apex of the tuangle is fiee
to move as heretofore explained, while the motion thereof 18 transmitted to the
lever "H" by a rod "0" which passes through the stuffing box "P."
A similar aangement to the last 18 shown in Fig. 4, but in this case the
triangle instead of being fixed inside the boiler 18 fixed inside of a box "N"
through which the hot water is made to pass on its way to and from the boiler
We do not bind ourselves to the particular methods of arranging the triangular
system of tubes or 1ods, there are other obvious ways of applying the motion
thereof to regulate the draught of hot water boilers and so to effect the purpose
herein set forth.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim 18:-
(1) The arrangement for automatically regulating heating apparatus sub-
stantially as herein set forth & described."
(2) In hot-water heating apparatus the combination of a thermostatic regulator
consisting of two tubes of metal through which the hot water is made to flow,
the said tubes having a different coefficient of expansion forming the two sides
of an 180sceles triangle being fixed at one end which is the base, and free to move
at the other end which is the apex of the triangle, an arrangement for trans-
mitting the said motion and an an regulator or damper foi regulating the heating
of the fine or water substantially as herein described
(3) In hot water heating apparatus the combination of a thermostatic regulato
consisting of two rods or tubes of metal placed in the boiler or in a vessel com-
municating with the boiler through which the hot water flows, the said two rods

page_text: or tubes having different coefficients of expansion and forming the two sides of
an isosceles triangle being fixed at one end which is the base of the triangle, and
free to move at the other end which is the apex of the tangle, an aliangement
for transmitting the said motion and an au regulator or damper for iegulating
the heat of the fire and water substantially as herein described
(4) In hot water heating apparatus the thermostatic regulator consisting of
two tubes or rods of metal, each having a different coefficient of expansion, the
said tubes or 1ods forming the two sides of an isosceles triangle being fixed
at one end which is the base, and fire to move at the other end which is the apex,
the said tubes 01 1ods being in contact with the hot water and having a movement
substantially as and for the purpose herein described
