attributes jointly convey adequate heat from a coal or coke fire or from the flame
of a lamp or stove in such manner that such heat may be optionally applied under
suitable conditions to the domestic hot water supply or to other purposes as desired
and whereas it is sometimes desirable that much heat be available for heating
water for use as hot water for various domestic purposes and at other times a much
less amount of heat is so required and indeed when a sufficient quantity of hot
water for pending requirements is already available in the hot water supply reser-
voir then for a period of time shorter or longer no heat whatever is wanted to be
applied to such purpose, and whereas in order to have a great amount of heat avail-
able for such purpose when required it is necessary to provide means for generating
such amount then when the time comes when little or no heat is required for the
specific purpose mentioned it frequently occurs that a great amount of heat is
wasted because of its not being readily divertible under suitable conditions to other
useful purposes although many such useful purposes might be acceptably served
by a ready means of diverting such heat otherwise wasted. I have devised and
invented the following arrangement, that is to say:-
My invention consists of a combination arrangement by which heat from the
same source or sources is optionally applied to the heating of water by coils in hot
water supply reservoirs, one or more, or is partly mainly or wholly diverted to
other purposes such as warming rooms or chambers, conservatories or greenhouses,
or other purposes which it may be desired to apply such heat to serve from time.
to time. Coils of tubing or tubes being so laid in contact with fire or flame as
to absorb and to impart to water within such coils or tubes such greatest amount
of heat as may be found to be practically available in each individual case from
these the apparatus is established in such manner that such heat or heat power
may be directed as above indicated. Valves stopcocks or other instruments and
fittings are to be laid in such manner as to direct as desired the heated water or
steam or heat power to serve either jointly or severally such required purposes as
the apparatus may be reasonably expected to fulfil. A regulator or governor valve
is connected with the apparatus in order that the degree of heat and pressure may
be to a sufficient extent under regulation and control. This regulator is intended
to be readily adjusted to any pressure as desired from zero, that is to say, from a
condition to add practically nothing to the ordinary atmospheric pressure, to about
one hundred pounds to the square inch as ordinarily set up, but in such cases

page_text: where the apparatus is constructed of materials of sufficient strength for very high
pressures then such higher pressure and corresponding heat absorbing and heat
imparting power as may be desired may be arranged for in such regulator.
Herewith is drawing showing in simple form the main features of the arrange-
ment forming the subject of this application as they may frequently be set up in
combination with ordinary arrangements.
In such drawing the following letters indicate respectively the following parts
operating as now set forth, namely:-
A. Feed cistern to apparatus.
B. Feed pipe. O. Check valve in such pipe to obviate back flow being set up
under high pressure.
C. Coil boiler of any suitable make readily absorbing heat in quantity, such
heat being water carried by way of pipe F to coil D, thereby being imparted to
water in hot water supply reservoir E. It is an essential feature in this arrange-
ment that the flow of heated water through pipe F may be directed as required
either partly or wholly through coil D, or several coils as D, or may be partly or
wholly diverted to other uses and for this purpose valves or stop-cocks as K* & L* are
introduced into the system of circulation in such manner that each and any one
or more may be partly or wholly closed as required to attain the desired purpose.
In any case the return to boiler is ultimately by way of pipe G as shown. In this
return coils as shown at H or other means may be introduced to enable water heat
to be applied to desired purposes. The extension of this return pipe is shown at I
to be arranged as an expansion or exhaust pipe in which is laid a regulator or
governor valve J. This regulator is adapted to the purpose of freely allowing the
circulating hot water or steam to pass to the feed cistern as shown when and only
when the desired heat pressure in the apparatus shall have been fully attained
and it is to be capable of being readily adjusted to varying pressures as desired
from time to time. In the regulator here shown this is effected by removable
weights W, pressing down to the desired extent a valve piece closing vent X until
the pressure to which such weights stand adjusted has been attained.
P&Q respectively indicate cold supply to hot water supply reservoir and hot
water supply from the same as ordinarily set up.

Improvements in Arrangements for Heating Water and Heating
generally for Domestic Purposes and Purposes allied thereto
under Regulated Pressure.
I, ARTEMAS YATES, Grasmere Cottage, Palatine Road, Northenden, in the County
of Chester, Commercial Clerk and Builder, 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: —
Whereas no present means so readily quickly and safely speaking of these
attributes jointly convey adequate heat from a coal or coke fire or from the flame
of a lamp or stove in such manner that such heat may be optionally applied under 4
suitable conditions to the domestic hot water supply or to other purposes as desired
and whereas it is sometimes desirable that much heat be available for heating
water for use as hot water for various domestic purposes and at other times a much
less amount of heat is so required and indeed when a sufficient quantity of hot

page_text: water for pending requirements is already available in the hot water supply reser-
voir then for a period of time shorter or longer no heat whatever is wanted to be
applied to such purpose and whereas in order to have a great amount of heat avail-
able for such purpose when required it is necessary to provide means for generating
such amount then when the time comes when little or no heat is required for the
specific purpose mentioned it frequently occurs that a great amount of heat is
wasted because of its not being readily divertible under suitable conditions to other
useful purposes although many such useful purposes might be acceptably served
by a ready means of diverting such heat otherwise wasted I have devised aud
invented the following apparatus. That is to say: -My invention consists of a
combination arrangement by which heat from the same source or sources is option-
ally applied to the heating of water preferably by coils in hot water supply reser-
voirs one or more or is partly mainly or wholly diverted to other purposes such as
warming rooms or chambers conservatories or greenhouses other purposes which
it may be desired to apply such heat to serve from time to time and which the
apparatus may be reasonably expected to fulfil.

Coils of tubing or tubes being so laid in contact with fire or flame as to absorb
and to impart to water within such coils or tubes such greatest amount of heat as
may be found to be practically available in each individual case, from these the
apparatus is established in such manner that such heat may be directed as above
indicated.
No particular shape or arrangement of coil boiler is essential to go with this
arrangement of apparatus but the coil boiler forming the subject of appli-
cation for Patent No. 3359 dated 9 Febry. 1897 is specially suitable as being
capable of absorbing a great amount of heat and also capable of standing con-
siderable internal pressure.
;
In Fig. 1 of drawings hereunto attached is shown such an arrangement of the
apparatus as may be most frequently and most advantageously set up in order to
attain the objects of this invention in any and every neighbourhood whatever the
character of the water supply may be and especially is this arrangement of the
apparatus forming the subject of this invention highly suitable where the water
supply is of a character likely to cause incrustation. In such drawing the follow-
ing letters indicate respectively the following parts operating as now set forth,
namely:
A Boiler coils.
B Pipe of iron or other suitable metal forming flow pipe in circulation with
necessary branches and unions.
At the top of this pipe is placed the regulator or governor valve hereinafter more
particularly referred to.
C Coil of copper or other suitable metal heating water in cylinder "E" (or other
hot water supply reservoir). It is an essential feature in this arrangement that
the flow of hot water through pipe "B" may be directed as required either partly
or wholly through coil "C" or several coils as "C" or may be partly or wholly
diverted to other uses and for this purpose valves or stop cocks as X" are intro-
duced into the system of circulation in such manner that each and any one or
more may be partly or wholly closed as required.
"
In any case the return to boiler is ultimately by way of pipe "D" as shown.
In this return coils or radiators as shown at "F" or other appliances are to be
introduced to enable water heat to be applied to desired purposes and in required
forms as steam or otherwise.
G is regulator or governor valve. Such instrument of any suitable material and
form may be chosen from the many various instruments readily purchasable or
may be easily constructed so as to adequately fulfil its purpose. The regulator of
whatever description is adapted to serve its purpose if it be such that it will freely
allow the circulating hot water or steam to pass to the feed cistern when and only
when the desired heat pressure in the apparatus shall have been fully attained,
and that it be capable of being readily adjusted to varying pressures as circum-

page_text: stances require, that is to say, circumstances varying from day to day or from
time to time as well as circumstances of a fixed or lasting character.
I Expansion pipe from cylinder.
J Cistern to feed pipe H supplying cylinder.
K Cistern to fed pipe L supplying coil circulation. This cistern is supplied
from cistern J by pipe in which is laid check valve M allowing water to pass
from J to K but not from K to J.
N Check valve to prevent back flow to cistern being set up under high pressure.
In many cases and especially in all cases where there is likelihood of the arrange.
ment being much used as a purely heating apparatus, that is when access to the
coils heating water in the hot water supply reservoir is likely to be cut off for
lengthy occasions it is intended that instead of this check valve simply allowing
water to pass by its own natural tendency there should be a small injector of any
suitable pattern introduced to pass water into the circulating pipes. Otherwise
there might be too much tendency to steam in the pipes with lack of water sufficient
to promote adequate circulation. Or, it may be easily arranged to have the
alternative use as desired of a check valye as shown or the injector as now men-
tioned by simply carrying up the pipe in which the check valve is laid to a suitable
position for the injector to be fixed and placing a stop valve for steam to pass to
the injector when it is required to work and shut off such action as occasion arises.
With regard to the arrangement of the apparatus as shown in Fig. 1 it is to be
understood that in order to obtain a high degree of safety in times of intense frost
it would be well to have no extra pressure beyond the ordinary atmospheric press-
ure in the circulation through the coils in the cylinder. It is advisable therefore
under such circumstances to stop the supply from cistern "K" to coil circulation
and to turn on the supply from cistern "()" shown in the drawing by dotted lines,
this latter supply being kept closed under ordinary circumstances to avoid over-
flow from the operation of the higher level of cistern "K." This cistern "O" is
thus an emergency supply and may be attended to by hand when ordinary supply
pipes are frozen. This emergency supply is under a much lower head than the
supply to cylinder and of course its use involves the temporary sacrifice of all
benefit that may usually be enjoyed from circulation for heating purposes on a
higher level but in order that such benefit may be again available without unneces-
sary loss of time it is well to have a connection as at "P" available when required
to allow heat to pass to cistern K" and so open up any frost bound pipes in
proximity thereto. The supply pipe from cistern J" to cylinder being laid in
contiguity with pipe "B" which passes through cistern "K" it is to be expected
that such supply pipe will generally remain open and free from frost or at any
rate will have become so by the time the water in cylinder may be approaching
boiling point and therefore a fair degree of safety may be expected of the apparatus
even without resort to the provision of cistern "O" as above mentioned insomuch
as the coil supply from cistern "K" is itself under a somewhat lower head than
the cylinder supply from cistern "J" though the difference is in this case only
very slight being in fact only so much as is due to the operation of the check
valve "M." The expediency of providing a cistern in a similar position to "O"
to be available when required is therefore very evident as it affords much greater
security that in case of frost bound pipes the water in the coil circulation will
steam off at a lower temperature than is required to generate steam in the cylinder
and create risk of explosion or other misadventure.

A less expensive but also less advantageous form or arrangement of the apparatus
forming the subject of this invention is shown at Fig. 2 on second sheet of draw-
ings. This is not at all to be recommended where there is the least tendency in
the water supply to cause incrustation and moreover in seasons of intense frost is
not so safe as the arrangement shown in Fig. 1, which is greatly to be preferred.
In this alternative arrangement similar letters so far as they are present denote
similar parts as in Fig. 1. It will be readily seen that the absence of a coil in
the cylinder makes a considerable difference in the detail working of the apparatus;

page_text: for instance the necessity of a separate feed or supply cistern to coils is obviated.
Also with access to the cylinder open the apparatus is subject only to the usual
atmospheric pressure plus the head of water, as is common, but when such access
is cut off by stop-cocks "R" and "S" the purely heating apparatus which the
arrangement then becomes may be subjected to greater pressure according to the
weight on the regulator or governor valve which is of course adjustable as may be
desired from time to time.
The remarks with regard to the introduction of an injector into the circulation
as above mentioned relative to Fig. 1 are also to a great extent applicable to the
arrangement shown in Fig. 2 when this is intended to work much as a heating
apparatus, but while it is at most only preferable in the arrangement shown in
Fig. 1 to have a direct supply by way of pipe "L" in which is laid check valve
at "N" it becomes imperative to have such supply independent of the injector in
the arrangement shown in Fig. 2 because in this arrangement it will frequently
happen that water will be drawn off for use necessitating a flow to replace the
same without such pressure being attained as would be necessary to pass the
regulator or governor valve and so set in action the injector which should of course
be so attached as to be operated by steam escaping along the vent pipe "Q
whereas in the arrangement shown in Fig. 1 there would in most cases practically
be no loss of water from the circulation except in the form of steam passing by
way of vent pipe "Q" and this of course would naturally set in action the injector
and so replace itself. Wherever this apparatus in any form as to detail arrange-
ments may be set up for the purpose of being applied as required to the heating
of a conservatory or like appurtenance to a house the floor of such appurtenance
being at a much lower level than the position available for the coils in contact with
fire or coil boiler it may be found to be highly desirable to lay the pipes carrying
the hot water circulation for the purpose of heating such appurtenance at as low
a level as may be found to be compatible with adequate circulation and it is hoped
that in practice this invention will be found to be of great incidental advantage in
this respect and in order to the maintenance of adequate circulation with such
lowest level of above mentioned pipes as may be by any means practicable it might
be well to reap the fullest advantage readily afforded by this apparatus as shown
in drawings herewith by increasing as much as conveniently possible the density
of the return water column throughout the whole or nearly the whole of its length.
This can be done as regards Fig. 1 for instance by fixing the turn or channel from
the upward flow to the downward return above the level of the supply cistern "J"
instead of below as shown in the drawing. This change in the position of such
turn will make it practicable to lay the downward return to pass through the said
cistern "J" in the form of a short coil thus cooling the return water column so
as to materially increase the density thereof and so admit of a deeper dip in such
return below the level of the boiler position than would otherwise be practicable
without greatly affecting the circulation power to rise from such dip back to the
boiler level. Of course in such adaptation cistern "K" would more conveniently
in most cases be otherwise supplied than from cistern "J." This modification
cannot well be shown by dotted lines or otherwise on drawing herewith but may

as X in both sheets of drawings will be readily understood and forms an important
feature in the arrangement though this particular disposal of them as to detail
arrangements is no part of the invention neither is it claimed that the introduction
of such is of itself the subject of this application for a patent nor is the com-
bination of a coil boiler of any form together with such stop valves and the like
in the circulation in a general way the subject of this application it being well
known that coil boilers and stop-cocks or valves have been long in use both
separately and jointly and it is not intended that this invention shall be taken as
being fixed solely with the particular disposition of details or parts as shown in
drawings herewith as many various modifications of the same may be readily
devised without departing from the general features of the invention which in the

page_text: main consists of a combination arrangement of the elements as hereinafter set
forth for the objects and advantages stated herein without further enumerating
others which may be found to incidentally arise. It is also to be understood that
element (a) as hereinafter mentioned is not to be taken as in any case meaning-such
boiler as may be used for the primary purpose of generating steam for engine or
other like mechanical power, it being well known that in many cases steam has
been diverted from such boilers to the purpose of warming workshops and factories
and I lay no claim to such invention which cannot be held to be contemplated in
the preamble hereunto which is intended only to apply to heat emanating from a
domestic hot water supply boiler and the beneficial utilisation of such heat by
diversion from the hot water supply to other purposes as required instead of being
so commonly wasted as at present.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is: -
(1) A combination arrangement for the purpose herein set forth of
(a) Coils of tubing or tubes in contact with fire.
(b) Regulator or governor valve readily adjustable to various pressures. as
required.
(c) Valves or stop-cocks or similar instruments by whatsoever named called
applied for the purpose of wholly or in part preventing the hot water circulation
from entering the hot water supply reservoir in order that the heat or heat power
of such circulation may be to a greater extent utilised for the purpose of warming
a room or chamber, greenhouse or conservatory or other desired purpose.
(2) Any apparatus for optionally imparting under regulated pressure water heat
from coils or tubular boiler to water in a domestic hot water supply reservoir or
applying such heat to other purposes as herein set forth or indicated, arranged sub-
stantially the same as herein described.
