PROVISIONAL SPECIFICATION.
Improvements in Steam Generators.
1, CHARLES HUELSER of the firm of Huelser & Co. of 142 Fleet Street, in the
City of London, Solicitors of Patents, do hereby declare the nature of this invention,
a communication to me from abroad by Henri Martin of Sotteville-les-Rouen, in the
Republic of France, Engineer, to be as follows:-
This invention relates to steam generators and has for its purpose to render the
placing out of work unnecessary, facilitate cleaning, afford increased safety and
considerable economy in fuel.
The improved steam generator essentially consists of six boilers each of which his
two manholes, a heating and feed boiler having two manholes with two tubes
serving respectively for the admission and discharge of the water and in its upper
part two pipes for feeding two cylindric chambers, each of which serves to supply
three of the six boilers referred to and is provided with a dome for the admission
of stean. Each dome has a manhole, tubes and pipes for compensating the steam
pressure, two pipes for the safety valves and two more for supplying the working
steam. Each three of the steam generators communicate with one of the said two
cylindric chambers through three steam conduits each of which consists of three
parts viz. one portion rivetted to the steam generator another rivetted to the
cylindric chamber and a central part in the shape of a cylinder of less than
50 millimetres in diameter. About 25 millimetres play is allowed between this
cylinder and the upper part of the conduit for cementing or packing by means of
iron rust cement or other suitab'e substance while the lower part of the cylinder
is widened to the inner diameter of and rivetted to the bottom part of the conduit,
said parts being united through their flanges by a bolt or bolts with anchoring
device.
The heating and feed boiler placed over the fore end of two furnaces, feeds the
cylindric chambers mentioned above through two pipes, thereby allowing the greater
part of sediment and impurities to be retained.
The heat and flames of the two furnaces, after playing about the bottom of the
boilers unite in the centre of a connecting chamber in which a brick partition is
provided on each side, are then divided and after passing the lateral conduits formed
by said partitions, re-unite in the flue.
It is evident that, the improved system favours a uniform distribution of heat and
efficacious evaporation while facilitating mounting dismounting and cleaning of the
boilers.

Improvements in Steam Generators.
I CHARLES HUELSER of the firm of Huelser & Co. of 142 Fleet Street in the City
of London, International Patent Agency, do hereby declare the nature of this inven-
tion, a communication to me from abroad by Henri Martin of Sotteville-les-Rouen,
in the Republic of France, Engineer, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
The object of this invention is a steam generator of comparatively simple construc-
tion excelling over other systems by increased safety considerable economy in
037

page_text: fuel and facility in repair and cleaning, while at the same time it need not be placed
out of work for any long period of time, when repairs are conducted.
Referring to the accompanying drawings Sheet I to V, in which like letters refer
to like or analogous parts throughout the different views,
Fig. 1 is a front view and partial section,
Fig. 2 a vertical section along line A B, Fig. 1, and
Fig. 3 a top view of the improved steam generator.
Figs. 4 and 5 represent details.
Fig. 6 is a front view and partial section.
Fig. 7 a vertical section along line C D Fig. 6.
Fig. 8 a top view of a modification.
Figs. 9 to 21 represent other modifications.
The improved steam generator consists of six or more boilers N each of which
has two man holes, a heating and feed boiler H provided with two man holes and
having two pipes, one for the admission and the other for the discharge of water.
This boiler has moreover at the top a pipe S for feeding a cylindric chamber M
which communicates through sleeves I with the rest of the boilers N. Or two
cylindric chambers M M', instead of one, are provided which communicate alternately
through sleeves I with boilers N. The chamber M, or chambers M and M², are
furnished at the top with a dome R or domes R and R' for the reception of steam.
Each dome has a man hole with pipes and tube for compensating the steam
pressure, two pipes for the safety valves and two more for the admission of steam.
The steam conduits or sleeves I consist each of three portions, one portion being
rivetted on the respective boiler, the other to the cylindric chambor, and a cylindric
internal piece 50 millimetres less in diameter. This cylindric piece is so shaped as
to leave about 25 millimetres play between the upper part of the conduit and the
respective portion of said cylindric body, said space serving to receive the packing;
the lower portion of the internal cylindric piece is widened and rivetted to the lower
portion of the sleeve. The two outer parts of the latter are so joined to each
other by means of flanges and bolts with anchoring device that in case one of the
boilers needs repair or is to be thrown out, it can be easily detached and replaced by
a reserve boiler.
The number and size of boilers and cylindric chambers depend upon the steam
power intended to be produced.
Each heating and feed boiler is placed above a furnace or furnaces and feeds the
respective chamber M which on its part feeds the rest of the boilers through the
conduits I.
The boilers being short, easily, accessible and numerous, they can be with facility
cleaned or repaired by several persons at the same time.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :
A steam generator as described, characterised by the application of a number of
dismountable boilers arranged side by side and communicating with a cylindric
chamber placed crosswise above said boilers or alternately with a number of such
chambers, substantially as set forth.
