page_text: LETTERS PATENT to Michael Joseph O'Riordan of the City of Cork for an
Invention of IMPROVEMENTS IN BOILERS OR APPARATUS FOR HEATING WATER,
COOKING OR OTHER PURPOSES.
PROVISIONAL SPECIFICATION left by the said Michael Joseph O'Riordan
at the Office of the Commissioners of Patents on the 11th September 1882.
MICHAEL JOSEPH O'RIORDAN of the City of Cork "IMPROVEMENTS IN BOILERS
OR APPARATUS FOR HEATING WATER, COOKING OR OTHER PURPOSES
"
The improved boiler or apparatus which forms the subject of my Invention is
composed of a vessel of enamelled iron, surrounded by an iron jacket, within which
steam is caused to circulate so as to boil, or heat, or cook the contents of the vessel.
Pipes for the admission and outlet of the steam are fitted to the jacket. A pipe
provided with a cock for drawing off the liquid contents of the vessel is connected.
with the lower part of the same and may pass through the steam jacket. Within
the vessel is a stirrer or agitator also of enamelled iron on a vertical shaft to
which rotary motion can be imparted when required by gearing working in suitable
supports above the vessel, and which may be disconnected at any time when not
required, as the apparatus may be used with or without it. The jacket has one or
more flanges, and may rest upon a suitable stand or support.
With apparatus constructed as above described the contents can be rapidly
boiled without the use of expensive tinned copper coils such as are now generally
employed in similar apparatus; and for cooking purposes the improved apparatus
can be substituted, where steam is available, for tinned copper or other vessels such
as are usually used on ranges, hot plates or fires.

MICHAEL JOSEPH O'RIORDAN of the City of Cork
"IMPROVEMENTS IN BOILERS
OR APPARATUS FOR HEATING WATER, COOKING OR OTHER PURPOSES,"
The improved boiler or apparatus which forms the subject of my invention is
composed of a vessel of enamelled iron or other suitable material surrounded by an
iron jacket, within which steam is caused to circulate so as to boil or heat or cook
the contents of the vessel. Pipes for the admission and outlet of the steam are
fitted to the jacket. A pipe provided with a cock for drawing off the liquid
contents of the vessel is connected with the lower part of the same and may pass
through the steam jacket. Within the vessel is a stirrer or agitator also of
enamelled iron on a vertical shaft to which rotary motion can be imparted when
required by gearing working in suitable supports above the vessel and which may
be disconnected at any time when not required as the apparatus may be used with
or without it. The jacket has a flange for a corresponding flange of the enamelled
iron vessel to rest upon and it may also be provided with a suitable stand or
support.
With apparatus constructed as above described the contents can be rapidly boiled
without the use of expensive tinned copper coils such as are now generally employed
in other apparatus; and for cooking purposes the improved apparatus can be
substituted, where steam is available, for tinned copper or other vessels such as are
usually used on ranges hot plates or fires.
Figure 1 of the annexed drawings is an elevation and Figure 2 a vertical section
of my improved boiler or apparatus. a is the enamelled iron vessel and b the iron
jacket surrounding the same. This jacket has a flange c at top upon which a
The two
corresponding flange d on the vessel a rests so as to support the same.
flanges may be secured together by screws or rivets as shewn. e is the inlet for
steam to the jacket and f the steam outlet. g is a pipe connected to the bottom of
the vessel a for drawing off the liquid contents of the same; this pipe is fitted with
a cock h. i is a stirrer or agitator of enamelled iron in the vessel a; it is carried
by a vertical shaft k to which rotary motion can be imparted when required by
gearing actuated by a handle m; this gearing can be disconnected when not
required. n is a stand or support for the apparatus but not connected or fastened
thereto.
Having now described the nature of my said invention and in what manner the
same is to be performed I declare that I claim :-
Constructing boilers or apparatus for heating water, cooking, or other purposes,
of an enamelled iron vessel or boiler surrounded by a jacket and heated by steam
substantially as hereinbefore described and represented in the annexed drawings.
In witness whereof I the said Michael Joseph O'Riordan have hereunto set
my hand and seal this seventh day of March One thousand eight hundred
and eighty three.
