PROVISIONAL SPECIFICATION.
A New or Improved Fire Box for Kitchen Ranges, Applicable also
for Vertical Steam Generators.
I, CHRISTOPH DELFS of Hamburg in the Empire of Germany 'mechanician, do
hereby declare the nature of this invention to be as follows:-
The object of this invention is a fire box for kitchen, ranges or vertical steam
generators which essentially consists of the fire chamber proper, the grating and tho
ash box, the whole being movably connected with the main body of the range or
steam generator in such a manner as to allow it to be raised or lowered according
to requirement by means of a crank or other suitable device provided outside the
apparatus. This arrangement serves to economize fuel and to admit of an easy and
rapid regulation of the heating effect.
The improved fire box is guided within the kitchen range or steam generator by
means of vertical guide rails and friction rollers or in any other suitable manner
and adapted to be secured in any desired position by aid of a convenient stop
device.

COMPLETE SPECIFICATION.
A New or Improved Fire Box for Kitchen Ranges, Applicable also
for Vertical Steam Generators.
I, CHRISTOPH DELFS, of Hamburg, in the Empire of Germany, mechanician, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to a new firing device more particularly for kitchen ranges,
but also applicable to vertical steam generators, and has for its purpose to effect a more
extensive utilization of the fuel than with similar devices hitherto known. This end
is attained in a very complete manner by making the fire grating vertically adjustable
relatively to the cooking plate or to the bottom of the cooking vessel or water reservoir
as the case may be.
Referring to the accompanying drawing,
Fig. 1 is a front view.
Fig. 2 a longitudinal section.
Fig. 3 a horizontal section, and
Fig. 4 a cross section of a kitchen range with the improved firing device applied
thereto.
On the sides of the fire door, two strong guide rails S are provided within the
range at the front side thereof. A frame, the sides of which are rigidly connected
with the fire box k, is vertically adjustable in said rails. The fire box is divided by
the plate p with grating finto two compartments, the fire chamber and ash box, which
latter is determined by the bottom u of the fire box. Around the grating, the fire
chamber is walled with fireproof bricks or other material, which however, in front, do
not exceed about two thirds of the height of the box.
To the bottom cross stay 9 of the framer is rigidly connected a toothed bar z
geared with a pinion g secured on a crank shaft w lodged in the front wall of the
range. A stop lever h, pressed by means of a spring e against a stop wheel t pro-
vided on the shaft w, secures the fire box in its position, which when correspondingly
Pies 27

page_text: changed, allows fuel to be introduced through the door a or the ash box to be drawn
out through the door b.
For the purpose of determining the fire box in its lowest position and securing the
the rack bar against lateral deviation, a peg' or tappet o is provided between the
guide rails s. The fire box moves in a space closed around, and only the fire chamber
proper communicates with the draught spaces of the range.
By the described arrangement, the fire-box is allowed to be adjusted to any desired
height, thus compelling the heating gases to act in a most efficacious manner. on the
cooking plate or on the bottom of the cooking vessel, whence they flow past the
frying oven B and boiler Wand pass through the pipe R into the flue.
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 I
claim is:
The application, in kitchen ranges, of a fire box & guided by means of a frame r
in rails and vertically adjustable by aid of crank shaft w; rack, pinion, stop-
lever and stop wheel t, substantially as and for the purpose set forth.
