PROVISIONAL SPECIFICATION.
Improvements in Boilers especially adapted for Engines used for
Agricultural Purposes.
I, DOMINIQUE GIBON, of Gilly, in the Kingdom of Belgium, Engine-builder,
do hereby declare the nature of this invention to be as follows:-
One of the drawbacks connected with the boilers of the class to which this
invention especially relates is that the water used for feeding them is muddy and
charged with great quantities of foreign matter and impurities calculated to injure
the boiler and interfere with the proper working of the engine. It is this defect
that the present invention is intended to remedy.
In boilers hitherto used the mud collects underneath the lower portion of the
furnace chamber and between it and the external wall of the boiler. The space
available at this part being very narrow, however, it frequently happens that the
wall of the boiler is burnt and thus rapidly becomes unfit for use.
In boilers of this description the furnace forms a rather bulky projection below
the body of the boiler. The object of this invention is to remove this projecting
part and to substitute for it at the lower portion of the boiler an incline extending
from end to end and adapted to receive the mud or other impurities which, owing
to the inclined position of the channel eventually collect underneath the furnace
at a point from which they can be readily discharged.
In a boiler constructed according to this invention an inclined metal sheet
separates the heating chamber from the lower external sheet of the boiler which
sheet together with the first named sheet form an inclined channel or water space
below the furnace.
The mud and other impurities after having collected in the upper portion of the
inclined channel slide down to the lower part where they accumulate and are
eventually discharged through a short tube or outlet.
Instead of one such outlet any desired number of them may be arranged along
the inclined channel or shoot so as to facilitate the evacuation and cleaning thereof;
The
and such outlets may if required be fitted with discharge or blow-off cocks.
advantages resulting from the arrangement described may be summed up as
follows
1. Facility of cleaning even while the engine is in motion ;
2. Diminution of repairs through the avoidance of damage by fire in the lower
part of the furnace due to an excessive agglomeration of mud ;
3. Saving of time through avoiding frequent repairs and
4. Increased cleanness and therefore better operation of the boiler and engine.

COMPLETE SPECIFICATION.
Improvements in Boilers especially adapted for Engines used for
Agricultural Purposes.
I, DOMINIQUE GIBON of Gilly, in the Kingdom of Belgium, Engine-builder,
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 water supplied to boilers employed in connection with portable engines or

page_text: other agricultural implements is generally muddy, dull in appearance and charged
with impurities. To avoid the inconveniences attending the use of such impure
water is the object of 'my invention. In boilers such as are generally used at
present the mud collects under the bottoms of the fire-place and boiler. This
space being very narrow the sheet-metal plates are rapidly damaged by the fire and
render the boiler at least 'temporarily unfit for use.
In boilers of this description a fire-place generally forms a somewhat considerable
projection beneath the main body of the boiler and it is the essential feature of
my invention to do away with this projection at the lower part of the boiler and
to impart to it an inclined shape from end to end, the object of such incline being
to collect the mud and other impurities which in consequence of the inclined shape
of the bottom will naturally collect underneath the fire-place from whence they can
be readily discharged through suitable orifices.
The invention will be best understood by reference to the accompanying drawings
in which
Figure 1 is a longitudinal section of a boiler embodying the novel arrangement
referred to and
Figure 2 is an end view of the boiler on the side on which the fire-place is
situated.
A is an inclined plate of sheet-metal separating the heat-chamber from the
external part of the boiler.
B is the inclined bottom of the boiler.
The mud and other impurities brought along with the feed-water first collected
at the upper part of the external incline of the boiler and then slide down this
incline to the lower part from whence they may be readily discharged through the
orifice C.
I do not limit my invention to the use of only one discharge orifice, as shown,
for a number of orifices of a similar or other construction may be arranged in
different points of the incline so as to facilitate the discharge and cleaning of the
boiler if necessary. To enable the boiler to be cleaned out even while in operation
such orifices C may be provided with discharge cocks D.
The advantages of my invention may therefore be summed up as follows:
1) Easy cleaning during the operation of the boiler;
2) Protection from damage from the combined action of the mud collected and
the flames so that the necessity of frequent repairs is avoided ;
3) Saving of time through avoiding repairs;
4) Increased cleanness of the boiler itself.
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
In boilers such as described the employment of an incline such as B extending
from one end of the boiler to the other and provided with one or more discharge
or cleaning orifices for the removal of mud and other impurities, during the
operation of the boiler substantially as described and illustrated in the accom-
panying drawings.
Dated this 30th day of September 1891.
