PROVISIONAL SPECIFICATION.
Improvements in Steam Generator Furnaces.
I, GILES HOLDING, Mechanic, 24 Ingleby Street Brownroyd Bradford Yorkshire,
do hereby declare the nature of my invention for IMPROVEMENTS IN STEAM GENERATOR
FURNACES to be as follows
-
The fuel is thrown on the firebars A, B, extending to a bridge D which spans the
fireplace, leaving a passage underneath to the latter portion of the fire-place. The
smoke arising from the fuel nearest the bridge D, is drawn under it, and becoming
heated by the incandescent fuel in the latter portion of the fire-place, produces
combustion, and passes up the air chamber c, c, behind the bridge D in a flame, the
heat of which causes combustion of the smoke passing over the bridge D towards
the flues.
Fig. 1 represents a longitudinal section Fig. 2 a sectional plan; and Fig. 3 a
transverse section. A are ordinary firebars B and C are bent metal bars, or they
may be straight, or inclined bars extending under the bridge D, which is composed
of fire-clay bricks, or metal, or other suitable material. E is a bridge to prevent the
fire being pushed into the flues. F, F, are fire-bricks placed at sides of fireplace
behind bridge D. g', g³, g³, g, are firebars with parts of surface inclined to form the
sides of the hollow portion of the fireplace, with air spaces as shown at e, e, e, e. The
centre bars B and C are supported under the bridge by a metal bar b, which is
secured by bolts, or pins and cotters to fixings d, d, which support the side bars, also
the bridge D, and the firebricks F, F.

COMPLETE SPECIFICATION.
Improvements in Steam Generator Furnaces.
GILES HOLDING 24 Ingleby Street, Brownroyd Bradford Yorkshire Mechanic do
hereby declare the nature of this invention and in what manner the same is to he
performed, to be particularly described and ascertained in and by the following
statement:-
In my improvements there are two combustions, viz. Low and high combustions.
The fuel is thrown on the firebars A, B, and B', extending to a bridge D, which
spans the fireplace leaving a passage underneath to the latter portion of the fireplace:
The smoke arising from the fuel nearest the bridge D, is drawn under it, and
becoming heated by the incandescent fuel in the latter portion of the fireplace,
produces the lower combustion, and passes up the air chamber C, behind the bridge D,
in a flame, the heat of which, causes combustion of the smoke arising from the front
of the furnace, which rises high and passes over bridge D, and is turned down by
arch E2, into the flame in the combustion chamber C, thus causing high combustion,
and passes into the tubes and flues in a massive flame.
:
The portion of the fireplace under bridge D, is made lower that there may be
sufficient amount of incandescent fuel to consume the smoke passing under the
bridge Also gives greater area for the heat arising from the combustion of the
smoke: Also the lower portion of the furnace as the advantage of the reduced area,
in the ash-place, where the force of air is weakest. Fig. 1 is a longitudinal section.
Fig. 2 sectional plan; and Fig. 3 a transverse section of furnace for generating
steam. A, and B, and B2, are ordinary firebars; B³, are bent, or may be straight
inclined metal bars, extending under bridge D, which is composed of fireclay bricks,
or metal, or other suitable material. E is a bridge to prevent the fire being

page_text: pushed into the flues; also turns the low combustion flame, to meet the smoke in
the higher part of furnace, and cause combustion. Arch E2, is composed of fireclay
bricks, or metal, or other suitable material. The bars at back end of furnace ; and
bridge D, are supported by metal plate G, which is built in bridge E'.
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 bridge D spanning furnace bars.
2. Arch E' around upper portion of furnace.
3. The inclined, or bent bars B³ as, and for, the purpose herein fully described and
illustrated.
