WILLIAM LEWIN Engineer 58 Bucks Road Douglas Isle of Man do hereby declare
the nature of this invention to be as follows:-
My invention relates to improvements in steam boilers, and consists of a method of
preventing "priming" by the use of corrugated plates, fixed by convenient means,
inside the boiler, in the steam space immediately above the water level. These plates
to be so arranged, that the steam by passing through the spaces between them will
"strike" against plates, immediately above these spaces, and any water which the
steam may contain, will be precipitated back into the water, thus effectually preventing
the passing of water with the steam to the engines.
Figure 1 shews a half section, and front elevation of a marine boiler, with the
corrugated plates as described above, A. A' and A2 are shewn fixed to the bottom row
of longitudinal stays, and at a convenient distance above the intervening spaces
are fixed the plates B and B¹.
Figure 2 shews a half longitudinal section and elevation, shewing these plates
running the full length of the boiler.
This invention is applicable to all kinds of land and marine boilers, of similar
general construction.
Having now particularly described the nature of my invention, and the manner in
which it may be applied, I would observe in conclusion, that I claim as my invention
the use of corrugated plates, for the purpose of preventing priming in steam boilers
arranged generally in the manner hereinbefore described, and as shewn on the
accompanying drawing.

Improved Means for Preventing Priming in Steam Boilers.
I WILLIAM LEWIN Engineer Douglas Isle of Man do hereby declare the nature of
my invention for THE PREVENTION OF PRIMING IN STEAM BOILERS, 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 Steam boilers and consists of a method of
preventing priming by the use of corrugated plates fixed by convenient means, inside
the boilers in the steam space immediately above the water level, and these plates to
be so arranged, that the steam in passing through the spaces between them, will strike
against plates; placed immediately above these spaces, and any water which it may
contain, will be precipitated back into the water; thus effectually preventing the
passing of water with the steam to the engines.
Referring to the drawing Figure 1 shews a half section, and front elevation of a
marine boiler. The corrugated plates are shewn fixed to the bottom row of
longitudinal stays, and the sides of the boiler at A, A¹ and A³, and on the row of
stays above, and above the intervening spaces, are fixed plates B and B¹ Figure 2
shews a half longitudinal section, and elevation shewing the corrugated plates, running
the full length of boiler.
This invention is applicable, to all kinds of land, and marine boilers.
Having now particularly described the nature of my invention, and the manner in
which it may be applied I declare that what I claim as my invention, is
The use of corrugated plates for the purpose of preventing priming in steam
boilers arranged generally in the manner hereinbefore described, and shewn on
drawing filed with provisional Specification.
