Date of Application, 5th May, 1899*
I, WALTER HUMBERSTONE, of Homestead, Crutchfield Road, Walton-on-Thames,
Surrey, Engineer, do hereby declare the nature of this invention to be as
follows:
This invention refers to boilers such as are used in kitchen ranges for heating
baths and like purposes.
These boilers usually present a flat surface to the fire and are furnished with
an arched flue beneath.
The object of my invention is to construct a boiler with a larger heating surface
exposed to the direct action of the fire, so that the water may be more rapidly
heated.
For this purpose I construct my improved boiler with a fluted or corrugated
surface either on the side towards the fire, or on the bottom where the flue passes
beneath, or on both.

For ordinary range use I form by preference one or more large flutes or corru-
gations on the front of the boiler, and in this way I largely increase the area
of the surface exposed to the fire's action. In order to cause a more rapid cir-
culation I partly enclose the concave side of these flutes inside the boiler by plates
which allow the water to enter beneath and pass out above when heated. These
plates are made removable for cleaning purposes and are fitted in some cases with
short pipes or sockets. The plates are kept in place by a cross bar sustained in
position by lugs on the boiler or in any other suitable way.
In this manner a rapid circulation of water inside the boiler is set up, and
thereby the deposit of lime is prevented or minimised. Moreover the heating of
the water is greatly hastened, and a considerable saving of coal is effected.

in and by the following statement:-
This invention refers to boilers such as are used in kitchen ranges for heating
baths and like purposes.
These boilers usually present a flat surface to the fire and are furnished with an
arched flue beneath.
The object of my invention is to construct a boiler with a larger heating surface
exposed to the direct action of the fire, so that the water may be more rapidly
heated.
For this purpose, I construct my improved boiler with a fluted or corrugated
surface, either on the side towards the fire, or on the bottom where the flue passes
beneath, or on both.
For ordinary range use I form by preference, one or more large flutes or
corrugations on the front of the boiler, and in this way; I largely increase the
area of the surface exposed to the action of the fire.
In order to cause a more rapid circulation, I partly enclose the concave side
of these flutes inside the boiler by plates which allow the water to enter beneath
and pass out above when heated. These plates are made removable for cleaning
purposes and are fitted in some cases with short pipes or sockets. The plates are
kept in place by a cross bar sustained in position by lugs on the boiler or in
any other suitable way.
In this manner a rapid circulation of water inside the boiler is set up, and
thereby the deposit of lime is prevented or minimised. Moreover the heating of
the water is greatly hastened, and a considerable saving of coal is effected.
I will now describe my invention with reference to the accompanying drawings,
in which,
Fig. 1 shews a perspective elevation of the boiler with the corrugations
arranged vertically.
Fig. 2 shews a horizontal cross section on the line 1-1 of Fig. 1, looking in the
direction of the arrows.
Fig. 3 shews a vertical section on the line 2-2 of Fig. 1, looking in the
direction of the arrows.
Fig. 4 shews a perspective elevation of the boiler with the corrugations
arranged horizontally.
Fig. 5, shews a vertical section on the line 3-3, of Fig. 4, looking in the
direction of the arrows.
Referring to Figs. 1, 2, and 3, a is the back part, and in Fig. 4, the upper
part, of the boiler, and b, b, are the corrugations in front, against which, the
fire impinges. c is a hand hole. The corrugations b, b, where they open into
the boiler, are each covered by a plate d, held tightly in position by a wedge
shaped locking bar e, the ends of which engage lugs e on the two sides of the
boiler. Each of the plates d, d, which are easily removable for cleaning, are
provided with orifices d², by which the water communicates with the corru-
gations, and ensures a rapid circulation.
Referring to Figs. 4 and 5, the construction of the boiler is similar to that
above described, but a vertical tube f is fixed in the orifice of the plates d
to facilitate circulation.
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. A boiler for heating water for baths and like purposes having projecting
flutes or corrugations exposed to the fire whereby a greater heating surface is
obtained, the recesses formed inside the boiler by said corrugations being partly
covered by movable plates which convert the corrugations into chambers to
facilitate the circulation of water, as herein described and set forth.

page_text: 2. In a boiler for heating water for baths and like purposes, the short tubes
fitted to the movable plates claimed in Claim 1, covering the open ends of the
corrugations the whole being designed to facilitate the circulation of the water,
as herein described and set forth.
