Domestic Use or for other analogous purposes.
We JAMES MARCROFT of 126 Platting Lane off Oldham Road Commission
Agent and CHARLES HEAP of Caldershaw Spotland Dyer and Fulling Miller
both in Rochdale and County of Lancaster do hereby declare the nature of this
invention to be as follows:-
This invention relates to an arrangement or apparatus for heating water for
domestic or other purposes principally for use in kitchen fire or other ranges for
beating the water for bath or set boilers to be used for washing purposes.
The object of our invention is to provide a simple and economical contrivance
for such purposes and which is capable of application to present fire ranges and
which we consider effective for the purposes herein set forth and of great use and
novel application, when applied to wash or set pans used in cottage houses.
The advantages of our apparatus are the economical form of construction,
minimising the risk of explosions as the water to be heated is distributed in a sinali
volume through the fire in the grate and there is a free and equal area of ingress
and egress or a free circulation of water through the apparatus and there is a ready
application of our invention to a variety of uses such as heating water for baths,
wash or set pans, or for warming purposes or for other analogous uses.
According to our present construction this invention consists of coiled metal
tubing of any suitable form but preferably of a grid iron form, having an inlet
and an outlet orifice the former connected with the ordinary water cistern or cold
water supply the latter to the ordinary hot water cistern or cylinder the diameters
of the inlet and outlet orifices of the coil are the same, the coiled tubing may
be situate against the ordinary fire brick back or may be embedded in a fire brick
plate or piece suitably recessed or moulded to receive the said coil so that when
in position the coil is level or flush with the face of the said plate or we may form
the grate of curved form in accordance with the form of fire grate as illustrated
in the Specification the subject of Letters Patent No. 4548 A.D. 1895 granted to
James Marcroft and one of the applicants herein in which latter case the heat of
the fire brick back may be reflected or thrown against the back of the bent coil
the above description of our invention applies only for purposes of heating water
for bath purposes.
According to our construction when applied for use in connection with an
ordinary kitchen side boiler or in connection with wash or set pans for cottage or
other use we connect both the inlet and the outlet orifices of the coil to the side of
the kitchen boiler so as to communicate with the interior thereof but so that one
orifice shall be at a different level to the other, that is, the inlet orifice is situate
at the lower part of the boiler the outlet orifice at the upper part thereof which
outlet may be immediately above or below the water level in the boiler in either
case as the cold water in the coil and passing from the boiler becomes heated
the hot water is ejected therefrom and so continues until the whole volume of water
attains a maximum temperature this arrangement applies to our apparatus fixed to

page_text: the ordinary side boiler only of a range, but when to be applied in connection with
a wash or set pan a connecting pipe may be attached at the lower and opposite
side of the kitchen boiler and conveniently connected with a set pan situate at any
suitable level with relation to the kitchen boiler and which may be situate in an
adjoining room or scullery which pipe or thoroughfare may be controlled by a
cock or tap allowing the hot water to pass from the kitchen boiler to the wash or
set pan when the hot water will obviously pass from one to the other maintaining
their respective levels according to the relative positions of one boiler with relation
to the other, thus hot water may be provided in the boilers simultaneously or the
connection may if desired be direct between the coil situate in the fire grate and
the set or other boiling pan which latter form of connection enables our arrange-
ment to be used in places where large quantities of hot water are to be used such
as in slaughter houses, restaurants for any of which above purposes hot water
may be quickly obtained and a further use of our invention may be for warming
purposes.

Improvements in and relating to Apparatus for Heating Water for
Domestic Use or for other analogous purposes.
We JAMES MARCROFT of 126 Platting Lane off Oldham Road Cominission
Agent and CHARLES HEAP of Caldershaw Spotland Dyer and Fulling Miller
both in Rochdale and County of Lancaster 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 an arrangement or apparatus for heating water for
domestic purposes principally for use in kitchen fire or other ranges for heating the
water for set pans or boilers to be used for washing purposes such as the washing
of clothes or wearing apparel.
The object of our invention is to provide a simple and economical contrivance
for such purposes and which is capable of application to present fire ranges, and
which we consider effective for the purposes herein described and of great use and
novel application when applied to wash pans or boilers used in cottage houses.
The advantages of our apparatus are the economical form of construction,
minimising the risk of explosions, as the water to be heated is distributed in a small
volume through the fire in the grate, there being a free and equal area of ingress
and egress or a free circulation of water through the apparatus.
Our invention admits of a ready application to a variety of uses such as heating
water for baths, wash boilers or for other analogous uses.
According to our present construction this invention consists of coiled metal
tubing of any suitable form, but preferably of a gridiron form, having an inlet
and an outlet orifice, the former connected with the ordinary water cistern or cold
water supply, the latter to the ordinary hot water cistern or cylinder the diameters
of the inlet and outlet orifices of the coil being the same or are equal.
The coiled tubing may be situate against the ordinary fire brick back or may be
embedded in a fire brick plate or piece suitably recessed or moulded to receive the
said coil, so that when in position the coil shall be level or flush with the face of
the said plate, or we may form the grate of curved form, in accordance with the
form of fire grate as illustrated in the drawings and described in the Specification

page_text: the subject of Letters Patent numbered 4548 A.D. 1895 granted to James Marcroft
and one of the applicants herein in which latter case the beat of the fire brick back
may be reflected against the back of the shaped coil, the above description of our
invention applies only for the purposes of hesting water for bath purposes.
According to our construction when applied for use in connection with an
ordinary kitchen side boiler or a wash boiler for cottage or other use, we connect
both the inlet and the outlet orifices of the coil to the side of the kitchen boiler so
as to communicate with the interior thereof but so that one orifice shall be at a
different level to the other, that is, the inlet oriñce is situate at the lower part of
the boiler, but the outlet orifice at the upper part thereof; which inlet may be
immediately below the water level in the boiler, in either case as the cold water in
the coil and passing from the boiler becomes heated, the hot water is ejected there-
from and so continues until the whole volume of water attains a maximum
temperature, this arrangement applies to our apparatus fixed to the ordinary side
boiler of a range, but when to be applied in connection with a wash boiler a
connecting pipe may be attached at the lower and opposite side of the kitchen
boiler and conveniently connected to a wash boiler situate at any suitable level
with relation to the kitchen boiler and which may be situate in any adjoining room
or scullery which pipe or thoroughfare may be controlled by a cock or tap, so as
to allow the hot water to pass from the kitchen boiler to the wash boiler, when the
hot water will obviously pass from one to the other maintaining their respective
levels according to the relative positions of the boilers, thus hot water may be
provided in the boilers simultaneously or the connection may if desired be direct
between the coil situate in the fire place and the wash boiler, which latter form of
connection enables our arrangement to be used in places where large quantities of
hot water are to be used such as in slaughter houses restaurants and by means
of which invention large quantities may be quickly heated.
The inlet and outlet orifices of the tubular piece or coil are also arranged to
communicate with a bot water cistern or cylinder and intercepting orifices arranged
to communicate with a wash boiler.
The orifices from the heating coil leading to the cylinder and to the wash boiler
respectively are controlled by the same three-way cocks or taps, whereby the water
may at will be allowed to circulate between the coil and the cylinder or between
the coil and the wash boiler or the water may flow from the cylinder to the pan
whereby hot water may be supplied for immediate use for clothes washing or other
purposes by the aid of or suitably operating the taps before named.
In order that a clear understanding of our invention may be had we have
hereunto annexed a sheet of drawings illustrating the application of our said.
invention in which like letters of reference throughout the various figures shewn
indicate like or similar parts.
Figure 1. represents an elevation of parts of a domestic fire range shewing the
application of our invention thereto and illustrating the connections thereof with a
hot water cylinder and a wash boiler.
Figure 2. represents a side view or elevation of the coil in section thro A. B.
Figure 1.
Figure 3. is a sectional view or elevation shewing the coil embedded within a
fire clay back or piece C.
Figure 4. is a modification of form of coil being the form referred to in the
Specification Number 4548 of A.D. 1895 bereinbefore referred to.
Figures 5. 6. and 7. are sectional elevations shewing the various positions of the
three-way taps when operated for the purposes hereinafter named.
According to our arrangement and hereinbefore referred to the construction
consists of a tubular heating piece or coil a. situate within the fire space b..in which
heat is by means of coal fuel employed for domestic heating purposes and which
coil terminates with a terminal a' at the underside of the cylinder c. and with a
terminal a' at the part d of the cylinder c.

page_text: At a convenient part or parts of the heating apparatus or coil terminals we
provide connecting pipes as a leading and connected with a wash or other boiler e
at which part or parts the orifices leading from the coil to the boiler and to the
cylinder respectively are controlled or governed by suitably arranged three-way
cocks or taps d. d', that is, ccmmunications between the heating apparatus and the
boiler or the cylinder may be effected by operating the taps d. and d or the tap d.
alone accordingly as it may be desired to place the coil in communication with the
boiler, in such event the taps are operated to the positions as shewn in Fig. 5. or
when it is desired to place the beating apparatus or coil in communication with the
cylinder c. then the taps are operated to the positions as shewn in Fig. 6. or when
it is desired to supply the boiler with water one of the taps, for example the tap d.
is operated to the position as shewn in Fig. 7, thus water from the cylinder may
circulate between the coil and the wash boiler, the coil and the cylinder or to flow
from the cylinder to the wash boiler.
In order to provide against the contamination of dirty water used in the boiler
during the operation of washing clothes and such water contained within the coil a.
with the water within the cylinder c. the tap d may be opened so as to admit water
from the cylinder to the coil but the tap d' must be operated so that a communica-
tion shall be opened between the coil and the boiler, the water from the cylinder
or level higher than the coil consequently forces out or expels the contents of the
coil through the pipe a³ into the boiler e. through the tap g when opened which
latter also passes off the contents of the boiler when required.
When the said dirty water has passed from the coil the taps d and d¹ may be
operated so as to allow of circulation between the cylinder and the coil.
We provide a perforated plate h. within the boiler e. to prevent articles within
the boiler obstructing the orifices i. i'.
The cylinder c. is situate in any convenient position relative to the boiler e.
which cylinder is an ordinary hot water cylinder supplied with water through the
pipe f. leading from a supply cistern provided with the usual accessories.
The boiler to be supplied with water and to be heated by our apparatus may be
situate in position as shewn i.e. fixed within the fire range or may be situate at any
other convenient part relative to the position of the heating apparatus or coil a,
such isolated position is indicated in the drawings herewith by dotted lines see
Fig. 1.
The position of the wash boiler may thus be in any position from the coil, may
be in a room adjoining that in which the fire range is situate in which case the pan
or wash boiler may be mounted or supported upon standards or supports obviating
in such a case the use or employment of a flue as would be the case for water
heating purposes by means of a furnace underneath the said pan as is now
the case.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. In combination a hollow or tubular coil a. having terminals controlled by
suitable taps d. d' which terminals communicate with a cylinder c. and a wash
boiler e. respectively, whereby water may be caused to circulate at will between the
coil and cylinder or the coil and wash boiler substantially as and for the purposes
herein fully set forth and described.
2. In combination the coil a. and the cylinder c. as and for the purposes herein
set forth.
3. In combination the coil a. and the boiler e. as and for the purposes herein set
forth.
4. In combination the cylinder c. and the wash boiler e. whereby through the
tap d. the said boiler may be readily supplied with heated water as herein set
forth.

page_text: 5. The coil a. provided with three way taps d. and d' and terminals as and for
the purposes herein set forth.
