PROVISIONAL SPECIFICATION left by the said Edward Evans at the
Office of the Commissioners of Patents, with his Petition, on the
18th June 1873.
I, EDWARD EVANS, of Seacombe, in the County of Chester, do hereby
declare the nature of the said Invention for "AN IMPROVED PORTABLE
APPARATUS FOR HEATING WATER AND OTHER LIQUIDS APPLICABLE FOR BATHS AND
OTHER PURPOSES," to be as follows:-
-
An apparatus constructed according to this Invention consists of.a.
length of small copper or other metal tube or piping, such tube being
coiled at the bottom in the form of a helix, and terminating at the top
in the form of a cylinder, which cylinder forms a funnel or chimney.
Outside of this coil there is fitted a cylindrical metal case forming a
reservoir of suitable size. -On the top of this case or reservoir there is a

page_text: cistern suitable to hold the quantity of water to supply the coil. From
the bottom of the cylinder a supply pipe passes down the centre of the
coil, and joins the coil pipe at the bottom of the helix. At the top of
the coil there is an overflow pipe, which opens into the before-mentioned
cylindrical case or reservoir round the coil. This pipe is fitted with a
draw-off cock or discharge pipe, which cock is so placed that when
open the water will overflow through it instead of into the cylindrical
case, and when shut the water overflows into the cylindrical case or
reservoir. The cylindrical case or reservoir is fitted with a draw-off cock
situated at the bottom thereof. The helical coil may be fitted with a
shield or guard of the same form, fitted outside the coil to retain the
heat. The heat is supplied by any suitable arrangement of gas jets or.
other heating medium, placed underneath the helical part of the coil.
The heat passes up the helical coil and through the funnel on the top
thereof, and plays on the under part of the supply cistern at the top of
the reservoir.
In using this apparatus, which is designated the "desideratum,"
water being placed in the supply cistern circulates through the coil,
becomes heated, and overflows into the reservoir, from whence it can be
drawn off for use..
In arranging the apparatus for supplying baths the supply of water
being allowed to flow into the supply cistern of the apparatus flows
through the coil, becomes heated, and is discharged into the bath
through the discharge cock and pipe at the top of the coil, the water in
passing through the coil becoming sufficiently heated for use.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Evans in the Great Seal Patent Office
on the 12th December 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
EVANS, of Seacombe, in the County of Chester, send greeting.

administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
PORTABLE APPARATUS FOR HEATING WATER AND OTHER LIQUIDS APPLICABLE FOR
BATHS AND OTHER PURPOSES," upon the condition (amongst others) that I,,
the said Edward Evans, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, .
should particularly describe and ascertain the nature of the said In-
vention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Evans, do hereby declare
the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and
by the following statement:-
•
An apparatus constructed according to this Invention consists of a
length of small copper or other metal tube or piping, such tube being..
coiled at the bottom in the form of a helix, and terminating at the top.
in the form of a cylinder, which cylinder forms. a funnel or chimney.
Outside of this coil there is fitted a cylindrical metal case, forming a.
reservoir of suitable size. On the top of this case or reservoir there is a
oistern suitable to hold the quantity of water to supply the coil. From
the bottom of the cylinder a supply pipe passes down the centre of the
coil, and joins the coil pipe at the bottom of the helix. At the top of
the coil there is an overflow pipe, which opens into the before-mentioned
cylindrical case or reservoir round the coil. This pipe is fitted with a.
draw-off cock or discharge pipe, which cock is so placed that when
open the water will overflow through it instead of into the cylindrical":
case, and when shut the water overflows into the cylindrical case or:
reservoir. The cylindrical case or reservoir is fitted with a draw-off cock
. situated at the bottom thereof. The helical coil may be fitted with a.
shield or guard of the same form fitted outside the coil to retain the
heat. The heat is supplied by any suitable arrangement of gas jets or

page_text: other heating medium, placed underneath the helical part of the coil.
The heat passes up the helical coil and through the funnel on the top
thereof, and plays on the under part of the supply cistern at the top of
the reservoir.
In using this apparatus, which is designated the desideratum, water
being placed or fed in the supply cistern circulates through the coil,
becomes heated, and overflows into the reservoir, from whence it can be
drawn off for use.
In arranging the apparatus for supplying baths the supply of water
being allowed to flow into the supply cistern of the apparatus flows
through the coil, becomes heated, and is discharged into the bath
through the discharge cock and pipe at the top of the coil, the water in
passing through the coil becoming sufficiently heated for use.
In some instances the coil may be made of several pieces, cach being
fed from the cistern and discharging into the reservoir..
.
In arranging this apparatus, especially for the supply of baths, it is
preferred to make the chimney casing or guard round the coil form the
inner shell of the reservoir, and to let the coil discharge into a cup or
gutter fixed round the top of the chimney, so that the water will run
down the heated sides of the casing or guard forming the chimney.
Above the casing or guard forming the chimney there is fixed a hood or
dome with a perforated casing, to throw down or reflect the heat given
off from the chimney.
When the apparatus is used for heating greenhouses or for obtaining
hot water for culinary and other purposes it is preferred that vertical
pipes should be substituted for the coil, so arranged that they lead from
the bottom of the reservoir to the cistern above, and from the cistern to
the top of the reservoir, so that circulation is insured.
The before-going being the nature and object of this my Invention,
I will now proceed to describe more in detail how the same may be
carried out into practical effect, and for that purpose I have hereunto
attached a Sheet of Drawings illustrative of my Invention as will enable
any practical person to carry the same into effect. Like letters and
figures in the various views denote similar parts, and correspond with
those in the following explanation :-
Figure 1 is a sectional elevation of an apparatus constructed according
to this Invention.

Figure 6 shows an arrangement for regulating the amount of gas
supplied to the atmospheric gas burner.
Figure 7 shows an arrangement of metal tube coiled in the form of a
helix.
Figure 8 shows an arrangement of metal tube coiled in the form of a
funnel, and one or more of which may be used over and with the coil
shown at Figure 7.
Figure 9 shows an outside clevation of an apparatus according to this
Invention arranged for supplying a bath.
a is a metal tube coiled in the form of a helix, and continuing and
terminating in the form of a chimney or funnel b; c is a cylindrical
metal case forming a reservoir; d is a cistern for holding water to supply
the coils; e is a supply pipe to the coil; f is an overflow pipe from the
coil discharging into the cylindrical reservoir c; g is a draw-off cock, so
placed that when open the water will run through it instead of through
the pipe f; h is a draw-off cock situated at the bottom of the reservoir c;
i and j, atmospheric gas burners; k, gas supply pipe; l, casing round.
coil for retaining the heat; m, perforated rose in cistern d for keeping
dirt out of the coil.
Referring to Figure 2 it will be seen that the coils a and b are made
in distinct parts, with distinct supplies and overflows e, e¹, and f, ƒ¹. It
will also be seen that the reservoir c is formed between the chimney
casing and guard and the outer shell of the apparatus. n is a cup
receiving the discharge from the pipe f; p is a hood or dome over the
coil for throwing the waste heat down; p¹ is a perforated casing
attached to the hood p; r is the overflow pipe from the cistern & and
the reservoir c, and may have a pipe at r¹ attached leading to the
bath.

page_text: Referring to Figure 3 it will be seen that vertical pipes a are sub-
stituted for the coil. These pipes lead from the reservoir c to the
cistern d; b are return pipes from the cistern d to the reservoir c; tand
u are provisions for coupling heating pipes to.

Referring to Figure 6 it will be seen that is a screwed wire used to;
regulate the supply of gas through the burner x.
Referring to Figure 9 it will be seen that C is the heater%3B D, the
bath; E, cold water supply; H, tap for drawing off hot water; I, over-
flow; K, hot water for bath; L, a hole in casing for lighting the gas;
M, gas supply and swinging lighter, which swings out through the hole L
for lighting purposes.
Upon reference it will be seen that cold water being supplied to the
cistern d flows through the coil or coils or vertical pipes a and b,
becomes heated, and is drawn or runs off from the cistern c as hot
water.
In using the apparatus for heating purposes the hot water flows
through the pipe t and returns through the pipe u.
Having now described the nature, object, and purposes of my In-
vention, and shown how the same may be carried into practical effect, I
wish it to be understood that I do not confine myself to the exact pro-
portions or dimensions of the apparatus as shown, as the same may be
considerably varied without departing from my Invention; but what I
claim as my Invention and secured to me by Letters Patent as
aforesaid is,-
Firstly. The improved portable apparatus for heating water and other
liquids, described in the before-going Specification and illustrated at
Figure 1 of the accompanying Drawings, substantially as set forth.
