page_text: I, THOMAS FLETCHER of Thynne Street Warrington in the County of Lancaster
Gas Engineer do hereby declare the nature of this invention to be as follows:-
This Invention relates to Gas Cooking Ranges and has for its object the more
effective utilization of the heat generated from the combustion of the gas by causing
the waste gases from the oven to heat or aid in heating water.
These Improvements consist in a novel combination adaptation or arrangement'
of a boiler or water heater to or with the gas cooking range.
The range with its oven and burners may be constructed in the usual or any
convenient manner. The boiler or water heater may be placed upon one side or at
the back of the range or upon the top of the oven. If it is placed at the top of the
oven it is arranged or fixed below the boiling burners in such a manner as to utilize
any heat that may be deflected downwards from those burners.
Within the boiler or water heater I construct a flue or tube or tubes connected
to the flue from the oven so that the waste gases from the oven pass through the
flue or tubes in the boiler and heat the water.
When a large supply of water is required or when it is desired to obtain it at a
bigher temperature, an auxiliary burner may be placed below, or in a suitable
position relatively to, the boiler or water heater in such a manner that the two
sources of heat do not interfere with each other,

page_text: I, THOMAS FLETCHER of Thynne Street Warrington in the County of Lancaster
Gas Engineer, 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 Gas cooking Ranges and has for its object the more
effective utilization of the beat generated from the combustion of the gas by
causing the waste gases from the oven or range to heat or aid in heating water.
These Improvements consist in a novel combination adapation or arrangement of
a boiler or water heater to or with the gas Cooking range.
'
And in order that this Invention may be more readily understood and carried
into practical effect I will now proceed to describe the same with reference to the
appended sheet of Drawings similar details or parts in the Figures thereon being
indicated by similar letters.
Figs. 1, 2, 3, and 4 represent in longitudinal and transverse section respectively
two examples of the arrangement which I prefer to adopt.
A is a water vessel, B its lid or cover, C a pipe or due through which the waste
heated gases from the range or oven are caused to pass. The pipe or flue C having
a large surface in contact with the water, the excess heat of the waste gases is to a
large extent transferred to the water. The inlet to the flue or pipe C may be con-
nected directly or by means of a connecting pipe to the outlet flue of the oven or
range and the outlet from C may be connected to a chimney or flue. In some
cases the openings shown in the figures as outlets may become inlets and the inlets
become outlets but I prefer the arrangement shown. The water vessel may in
most cases be placed with the greatest advantage side by side with the oven or
range and be supported at a convenient heigth by legs or supports. It may how-
ever be placed at the back or upon the top of the oven or range. If it is placed at
the top of an oven or range fitted with boiling burners it is arranged or fixed below
the boiling burners so as to utilize any heat that may be deflected downwards
from those burners.
When a large supply of hot water is required or when it is desired to obtain it
at a higher temperature, an auxiliary burner may be placed below, or in a suitable
position relatively to the boiler or water heater in such a manner that the two
sources of heat do not interfere with each other.
I am aware that water beaters having an internal flue have been employed for
heating water by means of the waste heat from industrial furnaces but I am not
aware that a water heater of the construction hereinbefore indicated has been
employed in combination with gas ranges or stoves,

page_text: 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) In combination with or as an addition to a gas cooking range, a water heater
having within the water space a tube or flue through which the waste heated gases
from the range may pass, substantially as and for the purpose herein before set
forth and described.
