PROVISIONAL SPECIFICATION.
A Smoke Consuming Furnace.
I, SYLVESTER EGGENBERGER, of 10, Museum Ring, Budapest, in the Empire
of Austria Hungary, Manufacturer, do hereby declare the nature of this invention
to be as follows:
The object of this invention is a furnace for heating boilers and the like in which
a complete combustion of the gases smoke etc. takes place.
Reference being taken to the accompanying drawings
Fig. 1 is a longitudinal section of the furnace.
Fig. 2 is a cross section on line ab Fig. 1 and
Fig. 3 is a cross section on line ed Fig. 1.
.
The furnace A is partly covered by the fire bridge B and by the protecting vault C.
Between the fire bridge B and the vault C is left a suitably large space through
which the fire gases pass underneath the boiler Cand into the flues connected with
the chimney. In order to protect the fire bridge B and the protecting vault C
against burning and also to carry into the furnace, the air necessary for the com-
bustion of the gases, said fire bridge is provided with air channels and and said
vault with air channels d d'. Along the furnace and behind the fire bridge extends
a cross channel E which communicates with the channels b
The fuel arrives from the inlet F upon the inclined grate G and can be easily
raked up from outside.
The Hames arrive in the narrowed part A' where they are mixed with the
incoming air previously heated in the channels d d' and '. Behind the fire
bridge Bare arranged one or more channels starting from the furnace A, which
carry the flames in front of the space A' located above the fire bridge B.
In case any non burnt gases or smoke should pass through the narrow part A'
the former will be ignited and burnt by the flames escaping from the channel
9.
As the inlet F terminates underneath the vault C whereby more fuel would collect
in the centre where the arch is higher than there would at the two sides an iron
cross beam K is cemented in between the vault and the inlet F. This beam causes
an equal falling down of the fuel upon the grate G whilst the slide L on the inlet F
serves for regulating the quantity of fuel travelling down onto the grate.

COMPLETE SPECIFICATION.
A Smoke Consuming Furnace.
I, SYLVESTER EGGENBERGER, of 10, Muscum Ring, Budapest, in the Kingdom
of Hungary, Manufacturer, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
The object of this invention is a furnace for heating boilers and the like in which
complete combustion of the gases, smoke etc. takes place.
Reference being made to the drawings filed with my Provisional Specification
Fig. 1 is a longitudinal section of the furnace.
Fig. 2 is a cross section on line ab Fig. 1, and
Fig. 3 is a cross section on line cd Fig. 1.
The furnace A is partly covered by the fire bridge B and by the protecting

page_text: vault C. Between the fire bridge B and vault C is left a suitably large space
through which the fire gases pass underneath the boiler C₁ and into the flues con-
nected with the chimney. In order to protect the fire bridge B and the protecting
vault C against burning and also to carry into the furnace the air necessary for the
combustion of the gases, said fire bridge is provided with air channels band and
said vault with air channels d d. Along the furnace and behind the fire bridge
extends a cross channel E which communicates with the channels b.
The fuel arrives from the inlet upon the inclined grate G and can be easily
raked up from outside.
The flames arrive in the narrowed part A where they are mixed with the
incoming air previously heated in the channels d d and 6. Behind the fire
bridge B are arranged one or more channels starting from the furnace A which
carry the flames in front of the space A' located above the fire bridge B.
In case any nonburnt gases or smoke should pass through the narrow part A' the
former will be ignited and burnt by the flames escaping from the channel
J.
As the inlet F terminates underneath the vault C whereby more fuel would
collect in the centre where the arch is higher, than there would at the two sides an
iron cross beam K is cemented in between the vault and the inlet F. This beam
causes an equal falling down of the fuel upon the grate G whilst the slide L on the
inlet serves for regulating the quantity of fuel travelling down onto the grate.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is :-
A furnace in which the space A. is covered by the fire bridge B provided with
the air channels and by the protecting vault C provided with air channels d d'
so that a suitable space A' is left between the fire bridge and the vault C for
allowing the fire gases to pass through in which space the gases are mixed with the
preheated air from the channels and d d and are ignited and burnt during their
further progress by the flames escaping from the channels y, substantially as illus-
trated and described.
