COMPLETE SPECIFICATION.
Improved Stoking Apparatus for Furnaces.
I, JULIUS WEZEL, of 17, Dresdnerstrasse, Leipzig, in the Empire of Germany,
Manufacturer, 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 for improved stoking apparatus for furnaces relates to apparatus
by means of which a complete consumption of the fuel is effected, and the fire can
be stoked whilst air is entirely excluded. This effect is secured by the arrangement
of stoking irons, that are pushed through the valve or flap in front of the grate,
carried over the grate and never completely removed therefrom, in order that the
opening in the flap or valve may be kept constantly closed.
In the accompanying drawing:
Fig. 1 is a sectional elevation of part of a furnace fitted with the improved
stoking apparatus.
Fig. 2 a front view, and
Fig. 3 a sectional plan view in the direction of the stoking irons.
The stoking irons D D' are composed of pipes bent to form parallel arms or
legs. Any desired number of such pipes may be distributed over the width of the
grate, the bent parts being above the grate, the open ends lying outwards, and
a handle bar e being provided for taking hold of the said arms or legs.
The arms or legs of the stoking irons are put through the place where the fire
is shut off, for instance, as shown in the drawing, through the valve or flap B,
and supported by the flap and a rest or bearing C.
The two stoking irons are connected with one another and with the admission
and discharge pipes E of a supply conduit, by means of india-rubber tubes or
hose G1 G2 G3, or tubes made in any other manner but being similarly flexible.
A pipe (Fig. 1) can also be carried from the conduit, for the purpose of cooling
the heads of the fire bars and the fire-bar bearers.
The opening for the admission of air to the grate can be furnished with adjust-
ing wings t (see Fig. 1) or any other suitable regulating apparatus for the
entrance of the air, notwithstanding the stoking irons are in constant cohesion with
the grate.
In the state of rest, the stoking irons have the position of the iron D, see Fig. 3,
and are completely drawn back, nevertheless fuel is always lying on them.
If the fuel is to be stirred, the stoking irons are pushed through, as D¹ Fig. 1
and 3, this being effected alternately with the different irens, in order that the
fuel may be thoroughly stoked. In view of this, the stoking irons are joined with
one another and with the conduit junction points by means of movable connecting
parts.
The stoking tubes being formed as connected arms or legs, by means of bendings
effected in any desired shape, these arms or legs remaining in the fuel and being
alternately movable, the fuel is more regularly stirred than if the stoking irons
had to be first introduced, and, in the case of inclined grates, sinks much more
uniformly.

page_text: The labour of the stoker is considerably facilitated by this invention, as the irons
lie always ready in the fire, through which, he can, consequently, work a much
larger quantity of fuel.
This arrangement can be applied with advantage to furnaces of any construction.
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:
Arrangement, or apparatus for stoking the fuel in furnaces whilst shutting
off the air, the distinguishing feature of which is that stoking irons D D¹ are
put through, the place B where the fire is shut off, in front of the grate, and over
the width of the grate, these irons consisting of pipes bent to form parallel legs
or arms, the "bendings" lying constantly on the grate and the open ends on the
outside of the fire-place, and being held together by means of a handle bar, and
connected with one another and with the admission and discharge pipes of a supply
conduit, by means of flexible pipe connections G¹ G2 G3, in order that a suitable
cooling effect may be produced and the double arm pipes D D¹ moved to and fro
for stirring the fuel, independently of each other.
