Improvements in Apparatus and Materials for Carburetting Air.
I, AUGUST KÖHLER, of Belle Alliancestrasse 64, Hamburg, Germany,
Technologist, 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 a construction of apparatus and selection and arrangement
of materials specially arranged therein for the purpose of carburetting air forced
through the apparatus and thereby producing a combustible gaseous fluid specially
adapted for illumination.
Fig. 1 of the accompanying drawings is a vertical section and Fig. 2 is a
sectional plan on the line X X of Fig. 1, of apparatus according to my invention.
A vessel A preferably of cylindrical form is made with a lower compartment
separated from the upper part by a horizontal partition B, and in this lower
compartment there is fixed a diaphragm C of wire gauze or finely perforated metal
sheet. The upper part of the vessel is divided into two compartments by a vertical
partition D and a horizontal partition E. A central pipe F extends down to
nearly the bottom; a laterally perforated pipe G extends through the partition B
and a laterally perforated pipe H extends through the partition E, a pipe K forms
the outlet at the top.
Both pipes G and H are closed at the top by screw caps, the spaces above the
partition B surrounding the pipes F G H are filled with porous or fibrous material
such as wood wool. The lowest compartment is charged with liquid which is a
mixture of 600 to 700 parts by weight of benzene with 1,200 to 1,400 parts of
petroleum such as boils at 120° C.
The pipe G is charged with 15 to 20 parts of camphor in granules and the
pipe H is charged with about the same quantity of naphthaline in granules. Air
forced by a pump or blower down, the pipe F bubbles through the liquid in the
lower compartment, ascends the pipe G passing through the camphor and issuing
by the lateral perforations into the fibrous material; thence it ascends the pipe H
through the naphthaline and the lateral perforations, and having thus become
carburetted passes by the pipe K to any suitable burner for heating or illuminating
purposes.
Fig. 3 is a diagram illustrating the general arrangement of the carburetting
apparatus and their connections AAA are carburetting vessels, L is a gas motor
engine working an air pump M by which air is forced through an elastic equalising
bag N to a main pipe P having branches to the several vessels A¹ A' A³. One of
these A' supplies the carburetted air through an equalizing bag O to the engine L,
the other vessels A2 A3 are shewn supplying several sets of burners.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. An air carburetting apparatus constructed and arranged substantially as
described with reference to the accompanying drawings.

page_text: 2. The use for carburetting air of mixed benzene and petroleum, of camphor and
of naphthaline through which substances the air is successively passed.
