page_text: We, RICHARD HAIGHTON LIMITED, of Vulcan Works, Nelson, in the County
of Lancaster, Kitchen Range Manufacturers, and ALBERT HAIGIITON, of the same
place, Iron Founder, do hereby declare the nature of this invention to be as
follows:-
This invention relates to wash or set boilers, and consists in providing the
same with an exterior metal casing furnished with a fire grate and a partition or
partitions for forming the respective flues, thereby dispensing with the usual
brickwork.
The casing is preferably constructed of cast iron, and is circular in form. It
is formed with a suitable fire grate, fire space and front opening for the admission
of fuel, and a hinged door to cover the opening. The set boiler is placed in
the casing, and is provided with a flange, which rests upon the top. An annular
channel or air space is left between the sides of the set boiler and our improved
casing. One or more circular horizontal partition plates are fixed between the
walls of the casing and the set boiler, and at suitable distances apart and form
the respective flues, around which the flames and heated gases circulate previous
to passing to the chimney. Heated gases from the fire grate first pass to the
back and around the set boiler, then pass through an opening in the first partition
at the back, then traverse the space between this and the second partition to
another opening at the front thereof, through which they emerge and proceeding
along the second partition or flue, finally make their exit at the back to the
chimney.
Although the exterior casing may be cast in one solid piece, we prefer it to be
cast in three pieces jointed or bolted together by overlapping flanges. A top
cover provided with a hinged lid is secured by nuts to the casing, two of the
overlapping flanges being provided with slotted extension pieces, to which the
said cover may be bolted. Clothes and water are introduced into the boiler
through the hinged lid.
Our invention not only renders set boiler very compact and enables them to
be fixed without the usual brickwork, but also permits of only a sheet metal pipe
being used as a chimney in substitution of the ordinary brick chimney.
Access openings with sliding lids are made at the sides of the casing, and
opposite the partitions, so that by raising such lids, the flues may be readily
cleaned.
A steam branch pipe may be fitted to the top cover of the set boiler to conduct
away steam arising from the boiling water in the boiler, the said branch pipe
being connected to the chimney.
Where the set boiler is fitted to a kitchen range, side pieces may be adapted

appearance.

We, RICHARD HAIGHTON LIMITED, of Vulcan Works, Nelson, in the County
of Lancaster, Kitchen Range Manufacturers, and ALBERT HAIGHTON, of the same
place, Iron Founder, 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 wash or set boilers, and consists of an improved
construction of the same. We provide wash or set boilers with an exterior metal
casing furnished with a fire grate and a partition or partitions for forming the
respective flues, thereby dispensing with the usual brickwork.
The casing is preferably constructed of cast iron, and is circular in form.
It is formed with a suitable fire-grate, fire-space, and front opening for the
admission of fuel, and a hinged door to cover the opening. The set boiler is
placed in the casing, and is provided with a flange, which rests upon the top.
An annular channel or air-space is left between the sides of the set boiler and
our improved casing. One or more circular horizontal partition plates are fixed
between the walls of the casing and the set boiler, and at suitable distances apart,
and form the respective flues, around which the flames and heated gases circulate
previous to passing to the chimney. The heated gases from the fire-grate first
pass to the back and around the set boiler, then pass through an opening in
the first partition at the back, then traverse the space between this and the
second partition to another opening at the front thereof, through which they
emerge, and proceeding along the second partition or flue, finally make their
exit at the back to the chimney. Although the exterior casing may be cast in
one solid piece, we prefer it to be cast in three pieces, jointed or bolted together
by overlapping flanges. A top cover provided with a hinged lid is secured by
nuts to the casing, two of the overlapping flanges being provided with_slotted
extension pieces, to which the said cover may be bolted. Clothes and water
are introduced into the boiler through the hinged lid.
Our invention not only renders set boilers very compact, and enables them
to be fixed without the usual brickwork, but also permits of only a sheet metal
pipe being used as a chimney in substitution of the ordinary brick chimney.
Access openings with sliding lids are made at the sides of the casing, and
opposite the partitions, so that by raising such lids, the flues may be readily
cleaned.
A steam branch pipe may be fitted to the top cover of the set boiler to conduct
away steam arising from the boiling water in the boiler, the said branch pipe
being connected to the chimney.
Where the set boiler is fitted to a kitchen range, side pieces may be adapted
to be bolted to the set boiler and the range respectively to improve the appearance.
In the accompanying drawings, Fig. 1 is a sectional elevation of our improved
wash pan or set boiler, and Fig. 2 is a plan view of the exterior casing, shewing
its particular construction.

page_text: Referring to Fig. 1, A is the exterior casing, upon which rests by means of
the flange B, the set pan or wash boiler C. The exterior casing is furnished
with a hinged door D, and a fire-grate E, upon which the fuel is placed. The
partition plates F and G form flues to cause the products of combustion to pass
in a serpentine manner from the fire-grate below to the chimney H. The heated
gases first pass to the back of the boiler, then through the opening in the
partition plate F into the chamber or flue J formed by such plate, then forward
to the front of the boiler, whence they emerge through an opening as indicated
by the arrow, into the chamber or flue formed by the second partition plate G,
before finally making their exit to the chimney.
A suitable cover K is designed to fit and rest upon the top of the exterior
casing A, and provided with a lid L hinged to a plate M bolted to the said cover
as shewn. A sheet metal pipe H constitutes the chimney in place of the usual
brick chimney, and into this is led the small steam pipe N for the escape of
steam from the hot water in the boiler. For increased draught, and to prevent
choking of the pipe or chimney H, the casing is cast with hemispherical outlet P
bulging beyond the external body of the casing.
Access openings with sliding lids are provided at the sides of the casing, and
near the partitions, so that by raising the said lids, the flues formed by the
respective partitions may be readily cleaned.
An essential feature of our invention consists in constructing the exterior
casing A in two, three or more pieces to facilitate casting. This will be readily
understood by reference to plan view (Fig. 2), of such casing. In this view,
the exterior casing is shewn as being constructed in three pieces Q R and S
formed with overlapping flanges T U and V. Bolts W are passed through such
overlapping flanges, and are secured by nuts to brace the parts together. The
pieces and R are secured together below outlet P in the same way as they
are shewn bolted to the piece S. Slotted extension lugs X are cast with one
or more of the said pieces Q R and S, to which the external cover K may be
fixed by providing the same with corresponding lugs bored, so that the same may
be bolted to the said extension lugs.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
:-
1. The combination and arrangement of parts of exterior casing A, having
fitted into it set pan C, and constructed substantially as described and shewn
in the accompanying drawings.
2. Forming the exterior casing of set pans or boilers in two or more pieces
provided with overlapping flanges or otherwise constructed, so that the same
can be cast in pieces, and bolted or secured together, substantially as described
and shewn in the accompanying drawings.
