PROVISIONAL SPECIFICATION.
An Improved Blast Heating Chamber for Smiths' Forges and like
purposes.
I, JOHANN KLIMEK, of Mokrau, near Nicolai, in the Empire of Germany,
Master-smith, do hereby declare the nature of this invention to be as follows:-
An intermediate chamber is placed between the bellows and the tuyere of the
forge and one side of this chamber abuts on, or forms part of the wall of the fire
box, or hearth, so that the chamber becomes rapidly heated when the fire is
burning.
This chamber is divided by a slanting partition and the blast impinging on this
is spread over the heated inner surface of the chamber and this becomes very
hot before reaching the fire.
By this method a much quicker and hotter fire can be obtained than by using
a cold air blast.

An Improved Blast Heating Chamber for Smiths' Forges and like
purposes.
I, JOHANN KLIMEK, of Mokrau, near Nicolai, in the Empire of Germany,
Master-smith, 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 present invention consists of an air mixing chamber for use in connection
with smiths' fires, said chamber being bricked into the wall of the fire hole,
between it and the bellows' nozzle and serving to mix the cold air coming from
the bellows with the warm air in the chamber previous to its entrance into the
fire.
In order to render the present specification more easily intelligible reference is
had to the accompanying drawing in which:
Fig. 1 represents a vertical section through a smith's fire and
Fig. 2 shows a cross section of the chamber and indicates the partition b.
The chamber A is bricked into the wall of the fire, one end c of the same lying

page_text: directly in or against the fire. The said chamber is divided into two parts by a
partition wall or baffle plate 6 having an upper orifice o and having its diameter
slightly smaller than that of the chamber so as to leave a small opening o¹, all
round which is only interrupted by the metal left to support the plate 6 in the
chamber. At the lower interior end of the chamber the nozzle e is placed whilst
the nozzle of the bellows d enters the part a of the chamber.
By means of this arrangement, the cold air entering the fire will first impinge
against the baffle plate b and then flow into the side c of the chamber where it
will be mixed thoroughly with the heated air therein, which is warmed by its
proximity to the fire, the plate b spraying the air into the said part c of the
chamber from whence it passes to the fire in a heated condition through the
nozzle 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 combination of a chamber bricked into the wall of a forge fire, and
having its inner end in direct contact with the fire, a baffle plate within said
chamber a nozzle at the lower part of its interior wall, and a bellows having its
nozzle extending into the exterior wall towards the baffle plate, substantially as
described and set forth.
2. The combination of a chamber A bricked into the wall of a forge fire as
specified, a baffle plate b therein, having an upper opening and space approxi-
mately all round between its edges and the inner walls of the chamber, a nozzle e
at the lower part of the inner end of the chamber and a bellows having its
nozzle extending through the outer chamber wall in front of the baffle plate,
.substantially as described and set forth.
