PROVISIONAL SPECIFICATION.
Improvements in the Setting and Heating of Retorts.
A communication from AUGUST KLÖNNE, of Dortmund, in the Empire of
Germany, and FREDERICK BREDEL, of Milwaukee, State of Wisconsin,
United States of America.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex
M.I.M.E., do hereby declare the nature of this invention to be as follows:-
This invention relates to the heating and setting of retorts. The invention
consists of:-
1st. An improved method of charging the fuel in the generator or fire box
from one side of the bench and doing the clinkering from the opposite side.
2nd. An improved method of supporting retorts which are set at an angle to the
horizontal line.
Wherever in this Specification reference is made to the front of the bench it all
times designates the side on which the discharging mouth-pieces lay. The opposite
side is called the back of the bench.
The generator or fire chamber is provided with a suitable grate partly or wholly
beneath the retort setting and filled with combustible material such as coke, coal or
other fuel for the purpose of heating the retorts. The fuel is supplied to the
furnace through a filling door at the front side of the retort bench. The clinkering
or stoking door lies on the opposite or back side of the retort bench. The object
of this improvement is to do away with excavation or an elevated stage or floor on
the discharging or front side of the retort bench, which would otherwise be necessary
in front of the bench, so as to provide for the clinkering and stoking of the fire and
discharging of the retorts.
It has been customary in setting inclined retorts to support them on blocks piers
tiles or other suitable structures of refractory material shaped to correspond with
the angle of inclination of the retorts which has not provided a substantial support
for the reason that the weight of the retorts will tend to drive the supporting walls
out of their vertical position and thereby give the retort a tendency to sag or bend
downward.
To obviate this the retort wherever it is supported by piers which are on both
sides exposed to the heat of the fire, are constructed with a circumferential ring or
offset made in one piece with and forming part of the retort and having a horizontal
supporting surface that is to say a surface which is horizontal when the retort is in
its inclined position thereby giving a substantial support and preventing all sliding
tendency and side pressure against supports.
Dated this 1st of June 1891.

page_text: my foreign correspondents, I declare that I am aware that it has been previously
proposed to form inclined retorts with snugs having horizontal supporting surfaces
& I lay no general claim to the arrangement for this purpose hereinbefore described,
but what I claim is :-
1. In a generator or fire box for the heating of retorts the combination with a
fuel charging door or opening such as C situated at one side of the generator of a
clinkering or stoking door or opening such as D situated at the opposite side of
the generator substantially as described and illustrated in the accompanying
drawings.
2. In the setting of inclined retorts the combination with one or more piers such
as V V of retorts provided with one or more circumferential rings having
horizontal supporting surfaces substantially as described and illustrated in the
accompanying drawings.
3. The combination and arrangement of parts constituting the complete retort
apparatus substantially as described and illustrated in the accompanying drawings.
Dated this 2nd day of March 1892.
