GAS-ENRICHER.

SPECIFICATION forming part of Letters Patent No. 557,086, dated March 24, 1896.

Application filed January l5, 1896. Serial No. 575 ,635. (No model.)

To @ZZ whom, t may concern:

Be it known that I, GEORGE G. SCHEOEDEE, a citizen of the United States, residing at Vashingtondn the District of Columbia, have invented certain new and useful Improvements in Gas-Enrichers and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

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 to so construct and arrange the parts of the apparatus that the amount of oil absorbed by the gas part of this specification, Figure l represents a perspective view, sectioned vertically and longitudinally, of a carburetor embodying the invention. Fig. 2 represents a detail side view, partly in section, of the inlet-pipe, iioat, and attachments. Fig. 3 represents a plan view of the parts shown in Fig. 2. Fig. 4f 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 c a. into the three compartments or chambers B, B and B2.

i B designates the oil-chamber into which the gas passes through the vertical pipe h, 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 anyproper source of gas-supply and is provided with a valve b to regulate the inward iiow 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 externallythreaded end of the pipe b and an internal horizontal portion d, having at lits end the hollow cylindrical socket c2 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 c2, so that gas will iiow 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 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 II is a tubular cap, internally threaded at its lower end to'screw down on said nipple. Above the tubular cap II is a vertically perforated or tubular en-Y largement I, provided with the transverse cutoff cock c', and above the said'enlargement is the funnel or hopper J, provided with the IOO transverse removable screen or sieve j, as shown in Fig. 4. The cap II, enlargement I and .hopper .I are preferably made in one piece, as shown in Fig. 4.

K, Figs. l and 4, is a tube passing through the nipple G and having a iange 7o surrounding its upper end and resting on the nipple to hold it from falling inward. The tube K is perforated at suitable points k t, and has its lower end closed by the disk k2, against which the knob f of the iioat 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 Z, and below said funnel with a stop cock or valve ZC By means of the funnel Z 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 B2 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 puriiied 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 purifyingchamber.

In operation the oil is fed to the chamber B through the funnel J, passing through the openings 7c 7:.' 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 7g2, so that the apertures 7s 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. Then the level of the oilin the tank sinks, the disk 7a2 falls, the said apertures are uncovered and the automatic feed again begins.

By means of the hopperl and pipe L asuitable heavy oil carrying a purifying agent, such as powdered alum, may be fed to the sponge in the chamber B', 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 p erforated partitions have been used, and such I do not desire to claim, broadly; but

Vhat I claim as new, and desire to secure by Letters Patent, is-

I. In a gas-enricher the combination with the oil-compartment, of a vertically-swinging gas-supply pipe entering said compartment, a delecting-plate and a float secured to the free end of said pipe, and an oil-feedingvalve 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 described.

2. In a gas-enricher, the combination with the casing divided by vert-ical, perforated partitions into an oil-receiving chamber, an oil-deliveringchamberand a purifying-chamber, situated between the oil receiving and delivering chambers, 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, iianged around its upper end to prevent its falling through said nipple, and having a closed lower end against which the top of the iioat impinges when the tank has a sufficient quantity of oil; thereby stopping the iniiow of oil through the perforations in said tube by moving them upward against the inside of the nipple, substantially as specified.

et. In a gas-enricher, the combination with the receiving-tank, the feed-pipe opening into 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 receiving-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 II having a suitable stop-cock and feeding-funnel, at its upper end, and the perforated tube provided with the iiange 7o at its upper end and disk 7a2 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-swing'- ing 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 delecting-plate E notched at c, e, in its edge,
