I, JOHN GEORGE AULSEBROOK KITCHEN, of 44, Albert Road, Alexandra Park,
Manchester, in the County of Lancaster, Mechanician, do hereby declare the
nature of this invention to be as follows:-
My invention relates to instantaneous steam generators and consists in an
improved construction of the same.
The improved generator consists of a preferably cylindrical vessel of consider-
able thickness of wall formed with a number of circular ribs, which preferably
are thick at the root next to the cylinder and thinner at their periphery. These
ribs may be cast in one with the cylindrical vessel, or be driven on.
The objects
of these arrangements is to obtain a great body of heated metal for the generation
of the steam, and cheapness of construction. The generator with ribs is sur-
rounded by a casing touching the periphery of the ribs or nearly doing so, and
the ribs have holes formed through them or parts cut out for the hot gases from
the burner or furnace arranged underneath the generator in the casing to pass
through, the openings in the ribs being so arranged as to break up the current.
The gases issue from the casing at the top of the generator in any convenient
way.
The bore of the generator is small in diameter relatively to the ribs, and is
surmounted by a dome shaped cover from which the steam is taken to the engine.
The feed water is introduced through a pipe descending in the centre of the
generator to near the bottom of the bore, and the water and steam ascend through
the annular space between the feed pipe and the walls of the generator to the
steam dome.
Improved Instantaneous Steam Generator.
I, JOHN GEORGE AULSEBROOK KITCHEN, of Heathwaite, Windermere, in the
County of Lancaster, late of 44, Albert Road, Alexandra Park, Manchester, in
the County of Lancaster, Mechanician, do hereby declare the nature of this inven-
tion 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 instantaneous steam generators and consists in an

page_text: On the drawing appended hereunto a steam generator constructed according
to my invention is shewn by Figure 1 in vertical and by Figure 2 in horizontal
section.
The improved generator consists of a preferably cylindrical vessel a of con-
siderable thickness of wall formed with a number of circular ribs b, which pre-
ferably are thick at the root next to the cylinder and thinner at their periphery,
as shewn on the drawing. These ribs may be cast in one with the cylindrical
vessel, or be driven on. The object of these arrangements are to obtain a great
body of heated metal for the generation of steam, and cheapness of construction.
The generator a with ribs b is surrounded by a casing or flue tube c touching the
periphery of the ribs or nearly doing so, and the ribs have holes 6' formed through
them or parts 62 cut out for the hot gases from the burner or furnace arranged
underneath or in front of the generator to pass through, the openings in the ribs
being so arranged as to break up the current of the flame. The burner or
furnace is not shewn on the drawings and may be of any suitable kind or con-
struction and does not form part of this invention. The gases issue from the
casing at the top or end of the generator in any convenient way, for instance
through the funnel d.
The bore or internal diameter of the generator is small relatively to the
diameter of the ribs, and is surmounted by a dome shaped cover e bolted to the
generator, from which dome the steam is taken to the engine through the pipe f.
The feed water is introduced through a feed pipe h into a lug e cast on the
steam dome, to which the internal pipe g is screwed. This pipe has an outer
diameter only a little smaller than the bore of the generator and descends in the
bore to near its bottom, the water and steam ascending through the narrow
annular space between the feed pipe and the walls of the generator to the steam
dome. Being thus brought in a small volume into close contact with the heated
walls of the generator containing a large reserve of heat, the water is instan-
taneously converted into steam.
The generator may be used in combination with a larger steam boiler as an
auxiliary apparatus for rapidly raising steam on starting the boiler, and be in
that case arranged in one of the boiler flues.
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
1. The arrangement or construction of an instantaneous steam generator sub-
stantially as herein before described and illustrated by the drawings.
2. In an instantaneous steam generator the combination of an externally
heated ribbed vessel having a circular bore and a great thickness of wall and ribs
relatively to its bore, and of a feed pipe nearly filling the bore and descending
near to the bottom or closed end of the vessel, substantially as hereinbefore
described and illustrated by the drawings.
