Improvements in or relating to Means for Smoke-consuming in
Boiler and other Furnaces and Fire-places.
I CARL STAUSS of 30 Heidestrasse Berlin in the Empire of Germany Manu-
facturer 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 :-
The object of this invention is to provide for an increased supply of highly heated
air in such a way as to consume the smoke.
To this end the invention consists in an apparatus, the essential features of which
are hereinafter described and specifically pointed out in the claims
Reference being made to the accompanying drawing
Fig. 1 illustrates the apparatus as applied to the furnace of a boiler of the Cornish
type being a cross section thereof.
Fig. 2 is a longitudinal vertical section thereof on line u u Fig. 3, and
Fig. 3 is a longitudinal horizontal section on line ev of Fig. 2.
Fig. 4 illustrates one of the component parts of the apparatus in sectional views.
Fig. 5 is a modified design suitable for small grates also shown by means of two
sectional views.
It will be understood that the apparatus can be applied to any furnace or grate
for burning fuel. For a furnace of considerable size, the apparatus is constructed as
follows. An oblong hollow iron frame a of suitable length is constructed preferably
flanged outward below to receive and uphold an outer protecting covering of fire-
brick fand of a height sufficient that when it is placed upon the cross bars supporting
the firebars (certain of which are removed or omitted to provide space for the frame)
the upper edge is on a level or nearly so with the fuel in the furnace. Upon this
frame a are supported along its whole length as many plates as may be conveniently
placed thereon said plates being shaped as in Fig. 4 so that when placed vertically
across the frame a spaces are left between them wider at the centre and narrower
at the sides for passage of air rising through the frame a and outlet of said air
laterally to mingle with the flames of the furnaces. Each plate bis for this purpose
hollowed towards the centre at ¹ and for retaining the plate on the frame a it is
provided with the tongue fitting into the frame as shown in Fig. 1. The bottom
opening of the frame a is closed by a register or shutter device c of any convenient
construction by which the inlet of air into the frame a may be brought under control.
In Fig. 2 a sliding perforated plate is moved in connection with a fixed perforated
plate by means of hand lever and gear d for this purpose. In the furnace shown one
of these apparatus is located along the centre of the grate there being two doors to
the furnace.
Where one door only is used the apparatus may be arranged along one side or
similar apparatus may be placed on each side so that the same does not or do not
constitute an obstacle to the firing.
For convenience of cleaning and repairs the plates 6 are made separate and
separate from the frame a but it is obvious that if desired such may be all made in
one casting.
In small grates and furnaces it is not necessary to make this smoke consuming
furnace of such size and for such grates, the modification illustrated in Fig. 5 will
suffice the effect of which is the same namely to carry up a certain volume of air and
substantially to direct it after heating radially or horizontally over the fuel.
This device consists of a number of V shaped plates assembled together as shown
so that narrow openings are left them, in communication with a central space or
an air uptake. The plates are held together by rings g' and g² and rest upon a

page_text: cylindrical piece y performing the part of the frame a. This apparatus may be and
preferably is made in one piece.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. In a furnace, the combination with the fire grate of a frame located therein
constituting an air uptake open for admission of air below said grate and having
lateral outlets for said air located at a distance above the grate substantially as and
for the purpose set forth.
2. In a furnace the combination with the fire grate of a frame located therein
constituting an air uptake said frame having an adjustable register for controlling
the admission of air below said grate and having lateral outlets for said air located
at a distance above the grate substantially as and for the purpose set forth..
3. The combination with a grate of a frame therein and a series of plates located
in said frame said plates being assembled to have lateral spaces between them
whereby said plates and frame constitute an air uptake with horizontal delivery
substantially as and for the purpose set forth.
4. The construction or constructions of air feeding or directing apparatus for
consumption of smoke as herein described with reference to the drawings.
