Complete Specification Left, 19th Feb., 1900-Accepted, 24th Mar., 1900
I, JAMES DUFFY, of 21, Howard Street, Burnley, in the County of Lancaster,
Tin Plate Worker, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to wash or set boilers, of that class in which a
condenser is used for condensing the steam arising from the hot water in the
boiler.
At the top of the boiler I fix a short pipe, which leads into a chamber of copper
or other metal of suitable dimensions. To this chamber, I attach another pipe,
which conveys the condensed steam or water back to the boiler. instead of allow-
ing the condensed steam or water to return to the boiler through the same pipe
as it entered.
By this means, the steam condenses quicker in my condenser than in others
at present in use, and a circulation of steam and condensed water is permitted
through the condenser and back to the boiler.

I, JAMES DUFFY, of 21, Howard Street, Burnley, in the County of Lancaster,
Tin Plate Worker, 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 has reference to wash or set boilers of that class in which
condenser is used for condensing the steam arising from the hot water in the
boiler.
At the top of the boiler I fix a short pipe, which leads into a chamber of copper
or other metal of suitable dimensions. To this chamber, I attach another pipe,
which conveys the condensed steam or water back to the boiler, instead of allow-
ing the condensed steam or water to return to the boiler through the same pipe
as it entered.
By this means, the steam condenses quicker in my condenser than in others
at present in use, and a circulation of steam and condensed water is permitted
through the condenser and back to the boiler.

page_text: The accompanying drawing is a detached perspective view of a wash or set
boiler fitted with a condenser arranged according to my invention.
A is the back portion or fixed cover of the boiler, B the lid hinged thereto.
Leading from the cover A is the expanded or funnel shaped pipe C communi-
cating with the receiver or condensing chamber D by means of a short length of
pipe E. The condensed steam or water finds its way through the short tapering
pipe back to the boiler.
The expanded or funnel shaped pipe C enables the free admittance into con-
denser D of the steam generated in the boiler, which quickly condenses, and
returns back to the boiler. A continued circulation of the steam and a rapid
condensation thereof are thus kept up, which not only get rid of the unpleasant
emission of steam between the lid and sides of the boiler, but also greatly increase
the temperature of the water contained therein, whereby a less expenditure of
heat is required, thus economising gas or fuel, as the case may be.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is
In a wash or set boiler a condensing chamber such as D), having a funnel shaped
or other suitably formed inlet pipe for the admission of steam for condensation,
and an outlet pipe F for the return of condensed steam back to the boiler, sub-
stantially as described and illustrated.
