Improvements in Gas Heating Apparatus.
I, LOUIS BROCK, of No. 19 Paul Strasse, Berlin N.W. in the Empire of
Germany, 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 :-
My invention relates to gas heating apparatus for use in furnaces or fire-places
of all kinds, including brick and lime kilns, ovens and the like.
The object of my invention is to provide for a preparatory heating of the air or
of the combustible gases, or both, admitted as fuel into a furnace or fire-place,
while being thus admitted, and the invention consists in the improved construction
and combination of parts more fully hereinafter described and shown in the
accompanying drawing, in which-
Figure 1 is a perspective view of a preferred construction of the improved
heating apparatus proper.
Figures 2 and 3 are a vertical section and a front elevation, respectively, showing
the improved apparatus in connection with a furnace or fire-place, the latter being
only partly shown in the drawing.
The improved heating apparatus consists, on the one hand, of a grate-like
support formed of a number of tubes a connected as shown in the drawing, and, on
the other hand, of a number of pieces of fire-brick or ore 6 loosely heaped up on
the said grate-like support, the tubes a being provided with discharge openings c,
as shown. Gas is admitted into the tubes of the support by a pipe such as d,
which may be connected, for the purpose, to any suitable source of gas supply.
The gas thus admitted escapes from the grate-like support by the apertures c, where
it is ignited and will cause the superimposed body of fire-brick or ore, as the case
may be, to become heated to incandescence.
Air may be caused to enter the fire-chamber through the body of incandescent
material, or gas may be admitted into the said fire-chamber by way of a pipe e
embedded in the incandescent material, or a mixture of air and gas may be admitted
in the manner described. By means of the arrangement shown such air or gas, or
mixture of air and gas, as the case may be, is subjected to a preparatory heating
on its way to the fire-box and before entering the latter. By this means a more
favorable heating effect is obtained than if the air or gas, or both, were admitted
in a cold state into the fire-place.
The heating apparatus above described is chiefly intended for being inserted
into the mouths of furnaces, ovens and kilns of every description in the manner
shown.
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. The combination, with a furnace or oven, of a grate-like tubular support
placed in the mouth of the furnace or oven and adapted to have a gas supply pipe
connected therewith, and provided with openings such as c, and a superimposed
body of loose fire-brick or ore, substantially as and for the purpose described.
2. The combination, with a furnace or oven, of a grate-like tubular support
placed in the mouth of the furnace or oven and adapted to have a gas supply pipe

of loose fire-brick or ore, and a gas supply pipe or pipes embedded therein,
substantially as and for the purpose described.
3. The grate-like support consisting of the pipes a with openings c.
