COMPLETE SPECIFICATION.
Improvements in Kitchen Ranges, Cooking Stoves, Heating
Apparatus, and Appliances connected there with.
I, HEDLEY STANLEY MOORWOOD, of The. Harleston Iron Works, Harleston
Street, Sheffield in the County of York, Ironfounder, 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 :-
The object of my invention is to provide an improved construction and arrange-
ment of boiler for heating water which although applicable to ordinary kitchen.
ranges, cooking stoves and heating apparatus, is more particularly designed to be
used in combination with a close range or kitchener such as is known as a
Leamington range which can be used with either an open or close fire and is also
well adapted to be used with a kitchen range provided with a grate having rising
and falling bars such as is described in the Specification of a Patent granted to me,
dated 16th February 1887, and numbered 2418.
Hot water boilers of the class herein referred to are frequently made of a form
known as an ell or boot boiler, i.e. the vertical cross section of such a boiler
resembles in form the letter L, or a boot.
Boilers of this class are commonly made either in cast-iron, wrought or
malleable iron, steel or copper, and the surfaces of the plates are made perfectly
plain both on the inside and the outside of the boiler.
My improved construction consists in forming the plates of such a boiler which
are exposed to the fire with ribs or corrugations for the purpose of increasing the
heating surface and strengthening the boiler, such ribs or corrugations being so
formed that, when the boiler is in position, they run parallel with the direction of
the flame.
In some cases I provide the whole surface of the boiler with ribs or corrugations,
in other cases I only provide the ribs or corrugations over the surface exposed to
the flame and in other cases I only so provide a portion of the surface exposed to
the flame.
When I employ ribs I sometimes place them on the exterior surface of the
boiler only and in other cases on the inside of the boiler only, or sometimes I
place the ribs on both the inside and outside surfaces of the boiler, such ribs
acting as heat conductors, by means of which the water in such a boiler may be
more quickly heated and with a less consumption of fuel than is the case with
boilers constructed of plates with plain surfaces.
The ribs or corrugations herein referred to may be either cast, forged, stamped,
pressed, rolled or otherwise formed on the plates as may be most convenient
according to the material employed in their construction.
My invention is particularly applicable to the arrangement and setting of such a
boiler upside down as is described and illustrated in a Patent granted to me and
another, dated 15th July 1889, and numbered 11,325, as may be seen on reference
to the accompanying drawings in which

my improved boilers, set upside down such section being taken on the line A. B.
(vide Figs. 2 and 3).

portion of the range which comprises the fire place, the hot water boiler and the
waste flue, the hot plate being removed.

page_text: k. is a tube or tubes, which in some cases, may be placed to carry the heat from
the front to the back of the boiler, such tube or tubes being placed either above
or below the damper as circumstances may require. In some cases I employ what
is known as the Serve or ribbed tube for this purpose.

The arrows in full lines indicate the direction in which the flame and waste gases
are directed along the heating surfaces of the boiler as ordinarily at work;
arrows in dotted lines indicate the direction the flame and waste gases will take
when the damper, e, is closed, which will be in the direction of the line C. to D.
between the underside of the hot plate, d, and the upper surface of the boiler, b,
and it would be this portion of the boiler where the ribs, corrugations or heat
conductors could be dispensed with.
When a boiler is constructed with a tube or tubes, j, the heated currents will
pass either up or down such tubes according to the position of the damper, e, and
whether it be opened or closed.
When a tube or tubes, k, are employed the heated currents may be directed
through them or otherwise according to the arrangement and position of the
damper, e.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In kitchen ranges, cooking stoves and heating apparatus the application of
an ell or boot formed boiler for heating water, the plates of which are constructed
with ribs or corrugations for the purpose of increasing the heating surface and
strengthening the said boiler, in the manner and for the purposes substantially as
herein described and illustrated.
2. The application of an ell or boot formed boiler for heating water, as described
in Claim 1, to an improved fire grate or fire place in which the fire bars, fire-grate
or hearth may be raised or lowered as is described in the Specification of a Patent
granted to me, dated the 16th February, 1887, and numbered 2418.
3. In kitchen ranges, cooking stoves and heating apparatus the application of
an ell or boot formed boiler for heating water as described in Claim 1, in com-
bination with the arrangement and setting of such a boiler upside down as described
in the Specification of a Patent granted to me and another, dated 15th July 1889,
and numbered 11,325, in the manner and for the purposes substantially as herein
described and illustrated.
Dated this 30th day of December 1893.
