IMPROVE- MENTS CONNECTED WITH SET-PANS OR BOILERS
Year: 1884

page_text: I, DAVID HALMSHAW, of New Bond Street, Halifax, Yorkshire, Machine Maker
and Whitesmith, do hereby declare the nature of my invention for "IMPROVE-
MENTS CONNECTED WITH SET-PANS OR BOILERS," to be as follows:-
This Invention has reference to set pans or boilers employed for domestic
purposes, such as boiling clothes previous to washing, brewing, and other purposes,
the object of my Invention being to cheapen the fixing of same, also to make them
portable, and to heat the water therein by means of gas and air.
Hitherto such pans or boilers have been built or set in brick work, surrounded
by a flue, connected to a chimney, there has also been a fire grate underneath the
boiler in order to heat the water therein.
According to my Invention I mount such pans or boilers within a sheet iron or
other metal casing, a flange on the said boiler resting on the top of the metal
casing. The top of the pan is provided with a sheet iron or other metal lid or
cover, to which is attached a short pipe to convey away the steam. A pipe with
one or more jets of gas combined with air is carried underneath the boiler for
heating purposes, and as the boiler is suspended at the top, there is ample space all
around the outside thereof for the hented gases to impinge against the metal,
thereby rapidly heating the water, which can be kept at one uniform heat if
necessary, without any further attention, which could not be done when a fire is
used for heating.
"
By arranging and fixing set pans or boilers in the manner herein set forth, they
оссиру less room, besides no brick work is required as neither flues nor chimnies are
necessary, consequently the first cost is considerably reduced, and less wear and
tear follows. The pans are also portable and can be moved about from place to
place, which in some kitchens is a desirable thing to do.

I, DAVID HALMSHAW of New Bond Street, Halifax, Yorkshire, Machine Maker,
and Whitesmith, do hereby declare the nature of my invention for "IMPROVE-
MENTS CONNECTED WITH SET PANS OR BOILERS," and in what manner the same.is
to be performed, to be particularly described and ascertained in and by the
following statement:―
This Invention has reference to set pans or boilers employed for domestic and
other purposes, the object of my invention being to cheapen the fixing of same,
also to make then portable, and to heat the water therein by means of gas and air
combined.
•
Hitherto such pans or boilers have been built or set in brick-work surrounded by
a flue connected to a chimney; there has also been a fire grate underneath the
boiler in order to heat the water therein.
According to my Invention I mount such pans or boilers within a sheet iron or
other metal casing, a flange on the said boiler resting upon the top of the metal
casing. The top of the pan is provided with a sheet iron or other metal lid or
cover to which is attached a short pipe with outlet-end stopped up which receives
the steam and, condenses it. A pipe with one or more jets of gas combined with
air is carried underneath the boiler for heating purposes, and as the boiler is
suspended at the top, there is ample space all around the outside thereof for the
heated gases to impinge against the metal, thereby rapidly heating the water, which
can be kept at one uniform heat if necessary without any further attention, which
could not be done when a fire is used for heating.
In order that my Invention may be better understood I herein give reference to
the accompanying sheet of Drawings wherein Fig 1 is front elevation of casing
with pan inside, Fig 2 is sectional elevation of same and Fig 3 sectional plan.
A is a sheet metal casing in which is placed the metal pan B, the flange C formed
on its upper end resting upon the top of the said casing by which it is suspended,
leaving a space all around the outside of the pan, so as to obtain the full effect of
the heated gases.
D is a circular pipe having any suitable number of holes or gas jets therein, the
gas being supplied thereto by means of pipe E. As gas used for lighting purposes
is not suitable for heating purposes in consequence of the smoke emitted therefrom,.
and also because the heat thrown off is not sufficient I mix the said gas with
atmospheric air preferably in the manner shewn in section Fig 4, where D is the
circular pipe, and E the gas pipe. It will be seen that the end of the gas pipe
enters into an open ended T union marked F in both ends a and b of which union
atmospheric nir freely enters and mingles with the gas, such mixture passing
through the pipe D and out of the holes formed therein, by which means the gas
when lighted will throw off great heat and rapidly boil the water.
The top of the pan is covered by a lid G provided with a pipe H, and is employed
for receiving the steam which is condensed therein. Although I have shewn and
described only one gas supply pipo D, it will be understood that two or other
suitable number may be employed, and that although I have shown the end of the
pipe D as being circular in form, it may be square or of other suitable shape
according to the varying shapes and sizes of pans and boilers.

page_text: By arranging and fixing set pans, or boilers in the manner herein set forth, they
occupy less room, besides no brick work is required, as neither flues nor chimneys
are necessary, consequently the first cost is considerably reduced, and less wear and
tear follows. The pans are also portable and can be moved about from place to
place, which in some kitchens is a desirable thing to do.
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
Firstly The suspension of a set pan or boiler at its upper end, so as to leave a
space all around for the heated gases to impinge against in manner substantially as
set forth.
Secondly. The combination of a lid and condensing pipe when employed in
connection with a pan heated by gas in manner as described.
Thirdly. The means or method herein described and shewn in Fig. 4 for mixing
atmospheric air and gas for purposes aforesaid.
