Improvements in Steam Generators.
I, EDWARD MAKIN Junior, of 40 New Brown Street, Manchester, in the County
of Lancaster, Manufacturer, do hereby declare the nature of this Invention
to be as follows:-
My invention relates to improvements in Lancashire, Cornish and similar types
of steam boilers in which an arrangement of cones or a similar appliance acting as
an aspirator is placed preferably behind the bridge in the furnace flue in order
to improve combustion."
My improvements consist principally in making the cones hollow or arranging
a water jacket around them or any equivalent device used as an aspirator and
supplying water preferably from the boiler or it may be from a separate source of
supply such as a pump or injector to this water space or jacket and delivering it
either as steam or water preferably back into the boiler or instead of supplying
water to the water space or jacket I may supply steam and use the apparatus as a
superheater.

I, EDWARD MAKIN Junior, of 40 New Brown Street, Manchester, in the County
of Lancaster, Manufacturer, 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:-
My invention relates to improvements in Lancashire, Cornish and similar types
of steam boilers in which an arrangement of cones or a similar appliance acting as
an aspirator is placed preferably behind the bridge in the furnace flue in order
to improve combustion."
My improvements consist principally in making the cones hollow or arranging
a water jacket around them or any equivalent device used as an aspirator and
supplying water preferably from the boiler or it may be from a separate source of
supply such as a pump or injector to this water space or jacket and delivering it
either as steam or water preferably back into the boiler or instead of supplying
water to the water space or jacket I may supply steam and use the apparatus as a
superheater.
The accompanying Drawing is a longitudinal section of a furnace flue or casing a

page_text: fitted with a series of hollow walled water or steam circulating cones 6 which are
supplied with water or steam through a feed pipe c and deliver it as steam or water
through a pipe d to the boiler e or elsewhere as desired.
The hollow walled circulating vessels 6 are preferably of the form shown, and
are treferably arranged as illustrated in the Drawing, with the large end of one
cone overlapping the small end of the preceding cone, thus leaving spaces between,
around the outsides, and through the cones for the passage of the heated gases
aspirated from the furnace.
The apparatus, arranged as shown or in an equivalent way, may be employed as
a water heater or steam generator or as a steam superheater.
It will be obvious that any number of the hollow walled circulating vessels may
be employed, and that the feed and delivery pipes instead of being connected to the
said vessels as shown may be otherwise connected and arranged.
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 :-
The arrangement use and application of any number of hollow walled water
or steam circulating vessels in a furnace flue or casing substantially as herein
described with reference to the accompanying Drawing for the purposes of water
heating or steam generating or steam superheating.
