GAS-CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 366,664, dated July 19, 1887.

A pplicatiou tiled March Q4, 1F86, Serial No. 106,370.

To aZZ whom it may concern:

Y Be it known that I, W. Oscan Hicknr., of Cleveland,'in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in GaS-Carburetors; and I do hereby 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 pertains to make and use the same.

My invention relates to improvements in gas-carbi'uetors in which a novel arrangement of wicks is provided for gi ving alarge evaporatingsurface and for thoroughly commingling the gases passing into the carburetor with the vapors generated therein; also, a gas-drying apartment is provided with mechanism for packing or regulating the density of the drying material, to the end that the gases are de livercd to the burner in good condition, and that by varying the density of the drying material the pressure of the gas flowing to the burners is also varied at pleasure. The stop* valves for the induction gaspipe and the fillingpipe ot' the container are connected with their respective ports at right angles to each other, so that but one valve can remain open at a time, tothe end that gas is not forced out into the room during the filling of the apparatus,and after the filling the valve of the induction gas-pipe is not forgotten and left closed.

Nith these objects in view my invention consists in certain features of construction and in combinations of parts, hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis a side elevation in section ofmy improved apparatus. Fig. 2 is a cross-section on theline off/12x, Fig. l, looking upward. Fig. 3 is a plan View of the duplex valve.

A represents the container, that is usually made of cast-iron, with a removable cast-iron cover, A. Connected with the cover are the induction and eduction gas-pipes, respectively, B and C, and the fillingpipe D. Connected with the bodyl of the container, and part way down the side thereof, is the overflow-cock F. The pipe B has a valve, b, for stopping the flow of gas from the meter to the container while the latter is being filled. rIhe pipe D has a stopvalve, d, that is only opened for filling the container. These two valves, therefore, should (No model.)

never both be closed or both open at a time. The two valves are therefore set with their ports at right angles to cach other-,and are then coupled in any suitable manner-for instance, by a sleeve or connecting-rod, as shown in Fig. 3-vso that both valves are operated silnultaneously, the one being opened as' the other is closed. .3y this means the valve b is not inadvertently left open while the container is being filled, and therefore isavoided the escaping of gas into the room, also, after iilling,the valve l is not inadvertently left closed, in which latter ease there would be no pressure of gas at the burners.

' Inside the contai ner, and depending from the cover thereof, are the hollow sheetlnetal cylinders E and C. The former is of considerable length, reaching to near the bottom ofthe container. Coarse wire screens care arranged top and bottom crosswise of the cylinder, and are held thus separated by the brace-wires e. Ordinary candle-wicking is passed backward and forward through the meshes ofthe wire screen, the strands of the wicking running substantially parallel. In this manner a mass of wicking is formed that loosely fills the cylinder and extends from top to bottoni thereof.

The pipe B discharges through the cover inside of this cylinder E. The cylinder, near the upper end thereof, has openings E. The cylinder G is comparatively short, as shown, and has two series of perforations, g and g', arranged circumfcrentially and near the bottom end thereof. \Vieking is drawn through the lower hol es, g, and bot-h strands extend to near the bottoni ofthe container, where they are gathered and tied, by means of which the ends are prevented from tangling with each other, and also the wicking isv brought in a funnel shape. Above the holes r/ is a disk'of wire-gauze, gi, that extends across the oylinder. 'Ihis gauze is usually supported by two or three stronger wires arranged below the gauze and secured on either side of the cylinder. rlhe space above the gauze is filled, or nearly so, with layers of wicking, preferably wound spirally and placed layer above layer. On top of the wicking is a perforated head, II. This head fits loosely in the cylinder G, and is moved vertically, to give more or less pressnre upon the wicks, by a set-screw, H. The

IOC

` set-screw were in line with the axis of the head,

the two might possibly turn together; but thev turning of the head would be likely lo roll the wicking and displace it.

The eduction-pipe C, that with its branches leads to the burners, opens through the head A inside of the cylinder G. The container A` is partially filled with some one of the lighter products of hydrocarbon oil, usually gasoline-that is, up to the line of the cock F, that is left open during the iilling for the purpose of gaging the depth of the liquid within. The liquid in the container is carried up by capillary attraction of the wicks in the cylinder E, and is evaporated and commingled with the gas entering through the pipe from the meter, the united product passing out at the holes E. From thence its only means of escape is either through the holes g or through the intersticcs of the wicking below. v In either case it is further enriched by the va'porization about the wicking vsuspended from the cylinder G. From thence the gas passes up through t-he dryingchamber. If the layers of wicking in this chamber areleft in a loose condition, there is but Vlittle obstruction to the passage of the gas, which would have at the burners substantially the same pressure as at the meter. The only effect in such case would be that the wicking operates as a drier and retains any atomized particles until they are converted into vapor, so that the gas,'after passing this drying-chamber, is in good condition for burning. By compressing this wicking, and thereby of course increasing its density, the passage ofthe gas through it is much retarded, so that the pressure at the burners may be reduced as desired. The gas from the meter, after having been enriched in passing through the carburetor, requires very much less pressure at the burner, and by turning down the set-screw H this pressure of the gas at the burner may be regulated at pleasure. The4 illuminating qualities of ordinary lighting-gas may be thus enriched fromrforty to sixty per cent., and this, too, at a trifling cost. Besides, the brilliancy of the flame is materially increased. Also, by regulating the pressure as aforesaid, all blowing at the burners and irregularities of the ilames are prevented.

I am aware that it is old to provide a gascarburetor with one or more evaporatingchambers; also, that it is old to provide a carburetor with a drying-chamber having a brous packing and provided with a platen, whereby the flow of gas may be regulated as well as deprived to a certain extent of its moisture; and hence I make no claim, broadly, to such construction.

What I claim is 1. In a gascarburetor, the combination, with a container having an overflow-cock, and an evaporating-chamber and drying-chamber located within the container, the latter being in a vplane above the overtlow-cock,of a lid or cover having inlet and outlet pipes connected, respectively, with the evaporating and drying chambers, and an oil-inlet pipe, substantially as set forth.

2. The combination, with a gas carburetor having an overflow-cock, of a drying-chamber located therein in a plane above the overflowc.:ck, and having suitable drying material arranged therein, and a movable disk or platen inside the drying-chamber and above the drying material therein, for compressing the drying material, substantially las set forth.

3. The combination, with a lgas-carburetor having an ovcrHow-cock and a drying-charn ber located within said carburetor in a plane above the oil-overflow cock, of drying material arranged in the drying'chamber, said drying material consisting of wicking coiled ina spiral form,with two or more layers piled the one upon the other, and a platen or disk for compressing the drying material, substantially as set forth.

4. The combination,withagas-carburetor, of an oil-overiiow-cock secured in the side there of, two or more evaporatingchambers located within the carburetor and in open relation with each other, a gassupply pipe leading into the firstoftheevaporatiiig-chambers,and adryingchamber located in a plane above the oil-over iiow cock in open relation with the last of the evaporating-chambers, said drying-chamber' W. osc'an Hicken.
