Improvements in Apparatus for Carburetting or Enriching Gas.
I, WILFRED IRWIN, of Wilton Polygon, Cheetham Hill, Manchester, in the
County of Lancaster, Chemist, 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:-
_
This invention is designed with the object of providing a convenient carbu-
rettor for enriching gas for factory or household use by means of benzol or other
enriching liquid.
It consists essentially of a carburrettor constructed of two vessels or chambers
preferably one superimposed above the other the upper one forming a holder
for liquid benzol and the lower one divided into a number of compartments
by vertical partitions which are filled with shavings coke or other suitable
material and fitted with suitable connecting pipes by which the benzol passes
from the top chamber to the lower one and the gas is led to and from the lower
chamber.
It will be fully described with reference to the accompanying drawings in
which a convenient form of the apparatus is illustrated.
Fig. 1, front elevation.
Fig. 2, sectional elevation.
Fig. 3, plan.
Fig. 4, sectional plan of enriching vessel B.
The apparatus is constructed with an upper air tight vessel A of rectangular
cylindrical or other convenient shape to contain a supply or quantity of benzol
or other volatile enriching liquid, and a second or lower vessel B of corresponding
or other suitable shape placed immediately below the vessel A (as shown) or in
other convenient position so that the benzol or enriching liquid can flow into
it from the containing vessel A.
The two vessels A & B are connected by a pipe through which the benzol
flows provided with a valve or stop tap c.
The containing vessel A is provided with an inlet a with screw plug or other
cover and a gauge glass D. The interior of the lower of the enriching vessel B
is divided into a series of compartment E opening one into the other by a number
of vertical partitions F. In these compartments E strips of absorbent material
such as flannel are suspended or attached to the sides of the partitions or shavings
pieces of coke or other suitable materials may be placed therein capable of
absorbing the benzol or enriching liquid as it flows through the aforesaid com-
partments to increase the surface with which gas comes in contact.
The gas to be enriched is caused to enter the lower or enriching vessel B by
the pipe G and flows through the several compartments E and out through the
pipe H. The gas as it flows through the vessel B is thus brought into contact
with the liquid absorbed by the material in the compartments and takes up or
absorbing a certain quantity of the liquid therein.
In large installations the vessel B is supplied with a coil or pipe K placed
either internally or externally through which water at a temperature of about
ונס...

page_text: 50° to 60° F., may be run to maintain the enriching liquid in the vessel at an
approximately uniform temperature.
The tube or pipe C connecting the two chambers is fitted with a stop tap c.
The amount of the liquid that flows into the lower chamber regulates itself.
automatically to correspond with the amount of liquid absorbed by the gas on
the well known principle of a "hen-fountain."
The lower chamber B may be fitted with a run off tap b and a second tap 61
by which the amount of liquid in the chamber can be ascertained or regulated.
The gas pipes G & H leading to and from the carburettor are carried up above
the level of the upper vessel A to prevent the possibility of the benzol or enriching
liquid finding its way into the gas mains. The inlet gas pipe G is provided
with a stop ap g and a bye pass L with a stop tap so that the whole or any
given proportion of the gas may be passed through the carburettor or the gas
may be passed direct to the service pipes in the ordinary course.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. A carburettor for enriching gas constructed with two vessels or chambers
one above or placed at higher level than the other to hold benzol or other enrich-
ing liquid and the other divided into compartments by vertical partitions provided
strips of absorbent material or loose material capable of absorbing the enriching
liquid the two chambers being connected together by a supply pipe and the
bottom one fitted with inlet and outlet pipes for the gas substantially as described.
2. In a carburettor for enriching gas the combination with the enriching
vessel of a water coil or tube to maintain the liquid at an approximately uniform
temperature substantially as described.
3. Apparatus for carburetting or enriching gas having the several parts con-
structed and arranged in combination substantially as described.
