JOHN FREDERICK GUSTAV KROMSCHRÖDER, of Walthamstow, in the County of
Essex, Engineer. IMPROVEMENTS IN MEANS OR APPARATUS FOR CARBURETTING
AND PURIFYING COAL GAS."
The Invention has for its object improvements in means or apparatus for car-
buretting and purifying coal gas. For this purpose I lead the gas into a chamber pro-
vided with a circuitous passage filled with horsehair or other absorbent material,
and supplied with a carburetting fluid from a reservoir situated above such car-
buretting chamber by means of a bird-fountain arrangement, so as to maintain the
liquid in such chamber at a given level.
The gas after traversing through the circuitous channel of the carburetting
chamber is led into a flexible storing chamber, the cover of which is weighted with
capability of regulation to suit the pressure required to cause the gas and the car-
buretting vapour to become intimately combined.
The gas after being carburetted and purified is led from this flexible chamber to
the burners by a pipe opening into the lower part of such flexible chamber.

plan on the line 1, 1, of Figure 1; and Figure 4 is a sectional under side view on
the line 2, 2, of Figure 1, representing my improvements in means or apparatus for
carburetting and purifying coal gas.
a is an inlet tube by which I lead the gas into a chamber 6 provided with a
circuitous passage filled with horsehair or other absorbent material, and supplied
with a carburetting fluid from a reservoir c situated above such carburetting
chamber by means of a bird-fountain arrangement, consisting of a supply tube
and air tube e, by which means the carburetting chamber 6 will have the fluid
therein maintained at the level of the lower end of the tube e, as immediately upon
the lower end of such tube becoming uncovered by the fluid, gas will find its way
up such tube, and thereby cause the fluid to descend by the tube d until the lower
end of the tube e is again sealed, when the supply will cease until it is again
uncovered.
The gas after traversing through the circuitous channel of the carburetting
chamber b is led into a flexible storing chamber f, the cover fl of which may be
weighted as described in my Provisional Specification, or it may be acted upon by a
spring bearing against a cross bar g to suit the pressure required to cause the gas
and the carburetting vapour to become intimately combined. The cover fl of the
carburetting chamber is guided in its motion by looped guides f² working on
vertical rods or wires f³.

The gas after being carburetted and purified is led from this flexible chamber f
through the aperture in the top thereof into the surrounding chamber h, whence it
passes to the burners by the pipe i opening into the lower part of the chamber h.
A float j rests upon the liquid in the chamber c, and by its rod j₁ the height of the
liquid in such chamber can be seen by looking through the glass dome or cover h.
Having thus described the nature of my said Invention and the mode in which I
carry the same into effect, I would have it understood that what I claim is, the

page_text: peculiar combination and arrangement of means or apparatus for carburetting and
purifying coal gas, substantially as herein shown and described.
In witness whereof, I, the said John Frederick Gustav Kromschröder, have
hereunto set my hand and seal, this Twenty-second day of May, in the
year of our Lord One thousand eight hundred and seventy-eight.
