I ADOLPH JULIUS LEHMANN of 12 Delamore Street Liverpool in the County
of Lancaster, Civil Engineer, do hereby declare the nature of this invention to be
as follows:-
The object is to construct or fit steam generators with appliances so mado and
disposed that circulation of wator is promoted and is made more nearly uniform
and general than heretofore.
The invention relates to horizontal flued steam generators in which there are two
or more combustion chambers, and consists essentially in enclosing the space or
spacos between such combustion chambers and in connecting the enclosure or
enclosures at or near the bottom by pipes tubes or suitable ways with those portions
of the generator which are occupied by the coolest water, the enclosure or enclosures
being made open above into the steam space of the generator.
To prevent priming I combine with the above appliances baffle plates disposed
above the openings leading to the steam space.
To further promote uniform and general circulation I combine with the above
improvements hoods or deflectors over or about the combustion chambers or flues
provided with ways passages tubes or openings substantially as above set forth.

DESCRIPTION OF THE DRAWINGS.
Figure 1. is a longitudinal section and figures 2. and 3. transverse soctions at
A. A. and B. B. of a horizontal flued steam generator having furnaces at oach ond
and a central combustion chambers fitted with my improvements, a. shell of generator,
b. horizontal flues, c. combustion chambers, d. enclosed space between combustion
chambers, e. pipes or tubes connecting the enclosed spacos to the portions of the
generator when the water is coolest, f. openings froin enclosures to steam space.
g. baffle plates over the openings f. h. deflectors or hoods over the flues having ways e.
and openings f., substantially as herein set forth.
It will be obvious that the construction and disposition of the enclosuros d. will vary
according to the number and location of the combustion chambers and flues. The
section fig. 2 shows how the closed spaces may be continued over the flues b.

page_text: Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed-I declare that what I claim is :-
:-
First. In horizontal flued Steam Generators having two or more combustion
chambers enclosing the space or spaces between such combustion chambers and
connecting the enclosure or enclosures to the steam or water spaces substantially
as in the manner and for the purpose set forth.
Second. Horizontal flued steam generators with an enclosed space or enclosed
spaces between combustion chambers constructed substantially in the manner and for
the purpose set forth.
Third. In horizontal flued steam generators having an enclosure or enclosures
as specified baffle plates disposed substantially in the manner and for the purpose set
forth.
Fourth. In horizontal flued steam generators having an enclosure or enclosures
with or without baffle platos as specified, hoods or deflectors, substantially in the
manner and for the purpose set forth.
