Improvements applicable to the Ascension Pipes of Gas Making
Retorts.
I, WILLIAM CLIMIE, of 9 McCroft Buildings, Lennoxtown, in the County of
Stirling, Engineer, do hereby declare the nature of this Invention to be as
follows:-
This Invention has for its object to provide means for preventing the carboniza-
tion, within the ascension pipes leading from retorts used in making gas from
coal, oil or the like, of the tarry matters which are carried off with the gas generated
in the retorts.
To that end I form water jackets around the ascension pipes by encasing these
pipes within pipes or jackets encircling or surrounding them and I circulate water
or other cooling fluid through said jackets whereby the tarry matters ascending
with the gas are liquefied and flow down the sides of the ascension pipes into
the retorts and are therein gasified or subjected to distillation.

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This Invention has for its object to provide means for preventing the carboniza-
tion, within the ascension pipes leading from retorts used in making gas from
coal, oil or the like, of the tarry matters which are carried off with the gas generated
in the retorts.
The Invention is illustrated by the accompanying drawings, Figure 1 being a
vertical elevation partly in section, and Figures 2 and 3 are plans of opposite
ends of the improved gas ascension pipe. Figure 4 is a vertical elevation partly
in section and Figure 5 a plan of a slightly modified form of gas ascension pipe
to which my improvements is applied.
In carrying out the Invention I form water jackets around the ascension pipes A.

page_text: by encasing these pipes within pipes or jackets B encircling or surroundling them
and I circulate water or other cooling fluid through said jackets B whereby the
tarry matters ascending with the gas are liquefied and flow down the sides of
the ascension pipes A into the retorts and are therein gasified or subjected to
distillation.
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 :-
An ascension pipe for gas making retorts constructed with a water jacket or
Jackets substantially as described.
