page_text: 1, JOHN WILLIAM SIZER of 1 Burbur Road, Clapham Common London S.W.
Wood and Stone Carver, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is the rapid heating of a volume of water, and also
continuously heating a supply of cold water and maintaining the same at a regular
and uniform temperature.
In accordance with my Invention, I employ a tank or casing of galvanised iron or
other suitable material, in the lower portion of which is formed a flame hood, or fire
box into which I may place a gas jet or jets, or a lamp with multiple wicks arranged
to consume mineral oils, or other hydro carbons. From said flame hood or fire box 1
arrange a certain number of vertical flues, passing upward into the tank or casing
above referred to. Said flues are constructed of sheet copper, or other material known
to be a good conductor of heat. A horizontal flue is placed so as to connect the
vertical flues aforesaid; and, upon the upper surface of said horizontal flue, a ledge,
say half an inch in depth is arranged so as to maintain a layer of water upon the
upper plate of the horizontal flue, and thus prevent it from burning when the water
level in the containing tank or casing is below said upper plate.
Two short vertical flues serve to connect the horizontal flue above mentioned with a
second horizontal fluo arranged above the first, and opening centrally from this is
another short vertical flue communicating with a third horizontal flue, from which
the gases resulting from combustion may be led into the atmosphere through a
Alue suitably arranged to communicate with a chimney placed at the side, or through
the cover of the containing tank to casing before referred to.
An ordinary ball cock or valve is connected through the side of the tank or
casing with the water main, or other suitable supply; and an overflow pipe is
also arranged so as to prevent flooding by reason of any accident to the ball cock,
or valve.
At the lower part of the tank or casing above referred to, I provide an outlet,
the area of which is three, four, or more times greater than that of the inlet of

page_text: cold water from the ball valve or cock, and I arrange that said outlet shall be
provided with an internal pipe, or, that the outlet orifice shall be above the bottom
of said tank or casing in such a manner as to ensure that several inches of water
must remain when the flow from the outlet ceases.
The operation of heating the water is carried on continuously by reason of the great
heating surface presented by the vertical and horizontal flues, and also the retardation
of the velocity of the heated gases consequent upon the tortuous passage formed by
said flues toward the chimney, and the action of convection allows of the incoming
cold water to be heated to the temperature of the outgoing water when the apparatus
is working continuously.
The device or contrivance according to my Invention may be applied to baths, of
all kinds, sculleries, washouses, and in fact to any purpose where hot water is
required in a short time and for continuous use at a uniform temperature.
Datod this Fifth day of March 1888.

page_text: I, JOHN WILLIAM SIZER of 1 Burbur Road, Clapham Common, London, S.W.
Wood and Stone Carver, 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 :—
The object of my Invention is the rapid beating of a volume of water, and also
continuously heating a supply of cold water and maintaining the same at a regular
and uniform temperature.
In order that my Invention may be the better understood I have appended the
accompanying sheet of drawings in which Figure 1 is a sectional view of a cistern.
or water tank showing in elevation the applianco according to my Invention arranged
therein. Figure 2 is a detached sectional clevational view of the appliance according
to my Invention showing by the arrows the circulation of the heated air therethrough.
Figure 3 is a view of a numbor of flues devised for use when my improved appliance
is to be used with hydrocarbon lamps; and Figure 4 shows a fluo devised for use with
a gas burner.
In accordance with my Invention, I employ a tank or casing A of galvanised iron
or other suitable material, in the lower portion of which is formed a flaine hood, Firo
box or flue B Figure 4, into which is inserted a gas jet or jets; or, I may employ a
number of such flues, C Figures 1, 2 and 3 in combination with which are employed
an equivalent number of hydrocarbon or other lamps. From said flue B or flues C
1 arrange a number of flat vertical tubes or conduits D, connected with the upper
surface of a flat horizontal tube E, to the lower surfaco of which is or are also
connected the flue B or flues C (as the case may be) aforesaid. Upon the upper
surface of the horizontal tube E is arranged a ledge a of sufficient depth to allow of
the retention therein of a small quantity of water in order to prevent the joints from
being injuriously effected by the heating medium, when the level of the water falls
below the level of said ledge a.
•
Two vertical flues F, F serve to connect the horizontal tube E with a horizontal
tube G to which latter are connected the upper ends of the above described
vertical tubes D.. At a suitable distance above the horizontal tube G, and communi-
cating with the vertical tubes F, F, is arranged a horizontal tube H to the
centre of which is adapted a vertical flue b. Another horizontal tube I is arranged
above the last referred to horizontal tube H, also connected with the vertical
tubes F, F, and is provided with a central vortical conical fluc c into which extends
some distance the nozzle shaped flue b in the horizontal tube H above referred to, the
two flues b and c serving to carry off the gases or vapors, after giving up their heat in
their passage through the various tubes above described.
Surrounding the horizontal tube G and flush with the upper surface thereof is a
narrow ledge & devised with the object of retaining therein sufficient water to prevent
the connections of the vertical tubes D with the horizontal tube G from being
injuriously effected by the direct heat from the burners, as previously described in
reference to the connections with the lower tube E.

page_text: An ordinary ball cock or valve J for controlling the supply of water to the cistern
or tank A is provided in a suitable position at the upper part thereof, as also an
overflow pipo f, for the usual purpose of carrying off the water when rising above a
predetermined height in the cistern or tank, as also for allowing of the escape of the
steam. At the lower part of the cistern is or are arranged a tap or cock g or taps or
cocks, for discharging the heated water to fill baths, for culinary, for heating and like
purposes in which a constant supply of hot water is requisito and desirable. Said
outlet g-which is attached in such a position to the tank or cistern A as to allow of
three or four inches of water in the bottom thereof, is preferably of very much
greater aroa than that of the inlet tap at J which supplies the cold water to the cistern
or tank A.
The object of the difference in area of the inlet and outlet cocks being to
prevent the too rapid cooling of the hot water during the discharge thereof by
the introduction of cold water from the ball tap or cock Jabove referred to.
The operation of heating the water is carried on continuously by reason of the great
heating surface presented by the vertical and horizontal pipes, and also by the
retardation of the velocity of the heated gases. consequent upon the tortuous passage
formed by said pipes towards the outlet vertical conical flues b, c, the action of
convection allowing of the incoming cold water to be heated to the temperature of the
outgoing water when the apparatus is working continuously.
The device or contrivance above described according to my Invention is applicable
for all purposes in which a large and continuous supply of hot water is required,
such for instance, as amongst others, baths, laundries, lavatories hotels and
the like.
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:
The improved apparatus herein described for heating water continuously and in
large quantities, substantially as herein set forth and shown in the accompanying
drawings.
