Coal, and other Bituminous Substances.
I, JAMES JONES of Dalmeny in the County of Linlithgow, North Britain Oil
Works Manager do hereby declare the nature of this invention to be as follows:-
This Invention relates to certain improvements in the construction of vertical retorts
for the destructive distillation of shale, coal, and other bituminous substances, and it
consists as follows:-
In benches of vertical retorts, the common practice is to set them in two rows with
their backs disposed towards each other, that is to say, towards the central part
of the setting, and the "snouts" or discharge mouths projecting outwards at the
bottom of each retort.
In retorts so constructed, hindrance to their efficient working is caused by the
clinker (or "dander" as it is sometimes called) collecting into a hard mass at
the back of the retort.
Under my improvements, the parts forming the backs of a pair of retorts, are
removed and the lower part of each pair thereof, is thus constituted into a chamber
common to the upper parts of the two retorts, or more strictly, which consists of the
two upper portions of a pair of retorts. In this mode of construction the parts upon
which the clinker or dander adheres, are got rid of, and I wish it to be understood
that my improvements may be applied both in the construction of new retorts, as well
as to the altering of existing retorts.
Doted this Thirty-first day of Anoust 1886.

I, JAMES JONES of Dalmetty in the County of Linlithgow, North Britain, Oil
Works Manager 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 certain improvements in the construction of vertical retorts
for the destructive distillation of shale, coal and other bituminous substances and it
consists as follows:-
In benches of vertical retorts, the common practice is to set them in two rows with
their backs disposed towards each other, that is to say, towards the central part of the
setting, and the "snouts" or discharge mouths projecting outwards at the bottom of
each retort.
In retorts so constructed, hindrance to their efficient working is caused by the
clinker (or "dander" as it is sometimes called) collecting into a hard mass at the back
of the retort.
Under my improvements, the parts forming the backs of a pair of Retorts are
removed and the lower part of each pair thereof, is thus constituted into a chamber
common to the two upper parts of the two retorts, or more strictly, which consists of the
two upper portions of a pair of retorts. In this mode of construction the parts upon
which the clinker or "dander" adheres, are got rid of, and I wish it to be understood
that my improvements may be applied both in the construction of new retorts as well
as to the altering of existing retorts.
In order that my Invention may be properly understood and readily carried into
effect, I will now proceed to describe the drawings hereunto annexed.
On the annexed sheets of drawings Figure 1, is a transverse section of the improved
retorts constructed in accordance with my Invention and Figure 2, is a section of the
same at right angles to Figure 1. In these Figures, the lower part of the retort
marked A, has no central division or back at the lower part as is usual in retorts of
this kind as hitherto constructed and consists therefore of an undivided chamber A;
common to the upper retorts or portions B, and C, respectively. The brick work D,
constituting the lower part of the chamber A, is constructed of fire brick or other
suitable material and is raised up to a central ridge for the requisite height as
there shewn.
By means of this arrangement there being no masonry or brick work between the
ridge marked E and the part marked F, the adhering of clinker or "dander" to
such brick work as hitherto used in such retorts is prevented and greater facilities
afforded for the drawing of the spent material from the retorts through the snouts or
mouth pieces G.

page_text: The other parts of the retorts shewn on the annexed drawings being common to the
class of retorts herein referred to and therefore constituting no part of my present
Invention need not be herein further described.
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 retorts for the distillation of shale, coal and other bituminous substances, the
constructing of such retorts with the lower chamber A, without a central division
and common to the two upper retorts or parts of retorts B, and C, substantially as
hereinbefore described and shewn upon the annexed sheet of drawings.
Dated this 4th day of May 1887.
