COMPLETE SPECIFICATION.
Improvements in Gas-enriching Apparatus.
I, GEORGE GALAGHER SCHROEDER, of 1344 G Street Washington, in the
District of Columbia, United States of America, Gentleman, 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:-
The invention relates to improvements in gas enrichers, the main objects being
to provide an apparatus of simple construction whereby the gas may be caused
to ascend through an oil sufficiently far to permit it to absorb enough of the oil to
give it the desired degree of illuminating power, and so construct and arrange
the parts of the apparatus that the amount of oil absorbed by the gas shall not
be subject to variation, but shall remain about constant, however much the amount
of oil in the receptacle or tank may vary.
A further object of the invention is to provide means whereby the apparatus
may be readily and quickly fed with the necessary amount of oil and purifiers, as
those in the tank are being used up or rendered inefficient or when the sponges
become dry. To these ends the invention consists in the novel construction and
combination of parts hereinafter described and claimed.
In the drawings accompanying and forming part of this specification
Figure 1 represents a perspective view, sectioned vertically and longitudinally,
of a carburetor embodying the invention.
Figure 2 represents a detail side view, partly in section, of the inlet pipe, float
and attachments.
Figure 3 represents a plan view of the parts shown in Figure 2.
Figure 4 represents a vertical sectional detail view of the oil feeding device,
hereinafter described.
Referring to the drawings by letter, A designates the box or case of the
apparatus, of rectangular shape and divided by the vertical, perforated partitions a, a¹
into three compartments or chambers B, B 1, B 2.
B designates the oil chamber into which the gas passes through the vertical
pipe b, the lower end of which is attached to and opens into the outer end of the
case A and chamber B at a suitable point at or near its center. This attachment
being made by a suitable coupling piece hereinafter more fully described. The
upper end of the pipe b is adapted for attachment to a pipe from any proper
source of gas supply and is provided with a valve b', to regulate the inward flow
of gas.
C designates the coupling piece referred to, the construction of which is plainly
shown in Figs. 2 and 3.
The said coupling piece comprises the vertical portion c, internally threaded to
receive the meeting externally threaded end of the pipe b, and an internal, horizontal
portion c¹ having, at its end, the hollow, cylindrical socket c³, to form a joint with
the adjacent end of the vertically swinging inlet pipe D.
The said end is enlarged and formed into a cylindrical, hollow head d and is
connected by a short tubular piece d' to the cylindrical socket 2, so that gas will
flow freely through the joint at whatever inclination the pipe D may stand.
The pipe D extends a suitable distance inward and has its inner end d² curved
downward and secured to the hemispherical deflecting plate E, into which it opens
near the top thereof; the said plate being notched around its edge at e, e, to
permit the gas to escape more readily thereunder, and to cause it to break up into
D27

page_text: globules or particles, so that it will come into more intimate contact with the oil
and consequently take up more thereof.
F is a float of any suitable form and light material, but preferably hollow and
globular and of sheet metal, provided on its top with a knob f, the purpose of
which is hereinafter explained.
G is a short vertical externally threaded nipple rising from the top of the
casing A at a proper point and H is a tubular cap, internally threaded at its lower
end to screw down on said nipple. Above the tubular cap H is a vertically
perforated or tubular enlargement I, provided with the transverse cut off cock i
and above the said enlargement is the funnel or hopper J provided with the
transverse removable screen or seive j, as shown in Fig. 4. The cap H,
enlargement I and hopper J are preferably made in one piece, as shown in
Figure 4.
K, Figs. 1 and 4, is a tube passing through the nipple G and having a flange k
surrounding its upper end and resting on the nipple to hold it from falling inward.
The tube K is perforated at suitable points k, k², and has its lower end closed by
a disk k², against which the knob f, of the float F is adapted to impinge.
L is a tube rising vertically from the top of the casing A communicating with
the purifying chamber B', and provided on its top with a suitable feeding funnel,
and below said funnel, with a stop cock or valve l¹.
By means of the funnel and tube L the sponges in the chamber may be kept
moist or saturated with any purifying liquid.
M is the outlet pipe for the gas after it has been enriched and purified. The
said pipe leads from the upper part of the compartment B 2 to any proper point
of storage or consumption and is controlled by the valve m, at a suitable point
near the apparatus.
This compartment provides a storage chamber for the enriched and purified gas
so that a free flow through the outlet pipe may be had, which would not be the
case if the mouth of said pipe impinged upon the sponge of the purifying
chamber.
In operation the oil is fed to the chamber B through the funnel J, passing
through the openings k', k', into said chamber. Now when the chamber has a
sufficient quantity of oil, the latter raises the float F, till the knob f presses up
the disk 2, so that the apertures k¹ are moved up into the nipple or sleeve G and
communication through them closed, thereby cutting off the feed from the funnel
or hopper J. When the level of the oil in the tank sinks the disk k² falls the said
apertures are uncovered and the automatic feed again begins.
By means of the hopper and pipe L a suitable heavy oil carrying a purifying
agent such as powdered alum may be fed to the sponge in the chamber B 1, so
that the sponge is at all times suitably moistened and at all times carries the
purifying agent in proper quantity to absorb or remove impurities such as coal tar
by a process like that of filtration.
I am aware that gas enrichers or carburetors having compartments separated
by perforated partitions have been used and such I do not desire to claim
broadly, but―
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. In a gas enricher the combination with the oil compartiment, of a vertically
swinging gas supply pipe entering said compartment, a deflecting plate and a
float secured to the free end of said pipe and an oil feeding valve communicating
with said compartment and located in the path of movement of the swinging gas
supply pipe, whereby the feed of oil is cut off when the compartment contains the
desired quantity, substantially as specified.
2. In a gas enricher, the combination with the casing divided by vertical
perforated partitions into an oil receiving chamber, an oil delivering chamber and

page_text: a purifying chanıber, situated between the oil receiving and delivering chamber,
of means for delivering a purifying agent to the purifying chamber, a vertically
swinging gas supply pipe entering the oil receiving chamber, and an oil feed valve
communicating with said chamber and located in the path of movement of the
swinging gas supply pipe, substantially as described for the purpose set forth.
3. In a gas enricher, the combination with the tank, the vertically swinging
tube therein, adapted to receive gas from any proper source of supply and the
concave depending plate, attached to a proper float and receiving gas near its
upper edge, from the upper end of said swinging tube, of the automatically closing
oil feeding device, essentially composed of a vertical nipple rising from the top
of the tank, at a proper point, the perforated tube, movable vertically in said
nipple, flanged around its upper end to prevent its falling through said nipple, and
having a closed lower end against which the top of the float impinges when the
tank has a sufficient quantity of oil, thereby stopping the inflow of oil through
the perforations in said tube by moving them upward against the inside of the
nipple, substantially as specified.
4. In a gas enricher, the combination with the receiving tank, the feed pipe
opening into the one end of the receiving tank, the movable gas pipe, free at its
inner end and pivoted at its outer end to a suitable coupling piece secured to the
inner surface of the outer end of the feed tank and having communication through
said coupling piece with the feed pipe and the float, substantially as described,
secured to the inner end of the movable gas pipe; of the oil feeding device
composed of the nipple G tube H, having a suitable stop cock and feeding funnel,
at its upper end, and the perforated tube provided with the flange k at its upper
end and disk 2 at its lower end; all constructed and arranged substantially as
shown and described for the purposes specified.
5. In a gas enricher, the combination with the casing, the gas delivery pipe
secured to the outside of the casing, the vertically swinging gas delivery pipe,
pivoted at its outer end, to a bracket secured to the inner side of the end of the
casing and communicating through said bracket with the outside delivery pipe and
the float attached to the inner free end of the swinging delivery pipe and composed
of the hollow sphere F and hemispherical deflecting plate E notched at e, e in its
edge, and opening near its connection with the sphere F into the gas delivery pipe,
of the automatic feed device consisting of the tube H and attached funnel and
stop cock, the tubular nipple secured within the tube H, and the perforated tubular
piece K provided with the upper and lower flanges k, k2 respectively, and with the
perforations k', k, substantially as specified.
