I, BENJAMIN HAINSWORTH, of King Cross Street, Halifax, Yorkshire, Ventilating
Engineer, do hereby declare the nature of my invention for AN IMPROVED
MEANS OF CONDENSING THE STEAM ARISING FROM PORTABLE OR OTHER SET-PANS,

This invention has reference to certain means to be employed for condensing the
steam arising from portable or other set-pans, and my improvements consist in
making one or more apertures in the lid and in placing over such apertures certain
domes or deflectors for the steam to impinge against which will assist in condensing
and spreading the said steam. At a suitable distance above such deflectors I place
one or more vessels or straight or coiled pipes supplied with cold water so that as
the steam emerges from the deflectors it will impinge against such cold water
pipes and be condensed thereby. In connection with these cold water pipes there
are suitable inlet and outlet pipes, the latter of which is in connection with the
boiler and provided with a tap so that the water in such pipe can be let out into
the boiler.

In combination with such cold water pipes (or they may be used alone) I employ
certain cold air tubes for the steam to impinge against for condensation.

I, BENJAMIN HAINSWORTH of King Cross Street Halifax Yorkshire, Ventilating
Engineer, do hereby declare the nature of invention for "AN IMPROVED MEANS
and
OF CONDENSING THE STEAM ARISING FROM PORTABLE OR OTHER SET PANS
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 certain means to be employed for condensing the
steam arising from portable or other set pans, and my improvements consist in
making one or more apertures in the lid and in placing over such apertures certain
domes or deflectors for the steam to impinge against, which will assist in condensing
and spreading the said steam.
In combination with such domes I place one or more vessels or straight or
coiled pipes supplied with cold water, so that as the steam emerges from the
deflectors it will impinge against such cold water pipes and be condensed thereby.
In connection with these cold water pipes there are suitable inlet and outlet
pipes, the latter of which is in connection with the boiler and provided with a tap
so that the water in such pipe can be let out into the boiler.
In combination with such cold water pipes (or they may be used alone) I employ
certain cold air tubes for the steam to empinge against for condensation.
In order that my Invention may be better understood I herin make reference
to the accompanying sheet of drawings, wherein Figure 1 is front elevation, and
Figure 2 section of a portable boiler or set pan having my improvements applied
thereto, A is the outer shell of the boiler, and B the round pan heated by gas from
the burner C, and D is the outlet for the consumed gases all arranged in the
ordinary manner.
In the lid E are suitable apertures which are covered by a dome or cover Fin
which dome I place a vessel Ġ filled with cold water. H. are open ended pipes for
the circulation of cold air so that as the steam arises from the water in the pan it
will impinge against the cold water vessel G, and against the cold air pipes H, and
the steam will be condenced thereby.
When the water in the vessel gets warm the tap I may be opened, and the water
therein run into the pan, fresh cold water being supplied at the funnel J.
Instead of employing the cold water vessel G, I may employ a coiled pipe K as
shewn in Figures 3 and 4, the former of which is elevation, and the latter plan
view. It must be understood that the coiled pipe is not made into a complete
coil but at points a and b the pipe is made to return again, and this is done so
that the clothes to be boiled can be introduced and removed from the pan at the
door L

page_text: This coiled pipe is filled with cold water which condenses the steam as it comes
into contact with the said cold water pipe, and when the pipe geta warm the
water can be let off into the pan by opening the tap M. Fresh cold water is
introduced at the funnel N. By these means the steam is condensed, and the
kitchen where the washing is performed is kept cool, and free from steamy vapours.
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 as my invention is;
The means of condensing steam arising from set pans in manner substantially as
herein shown and described.
