To all whom it may concern.-

Be it known that I, MATTHEW STEEL, a subject 01 the Kin of Great Britian and Ireland, and a resident of Gosforth, in the county of Northumberland, England, have invented certain new and useful Improvements in Carbureting Apparatus, of which the following is a specification.

This invention relates to carbureting apparatus, and has for its object to provide asimple and efficient apparatus for carbureting air for lighting, heating, or other purposes.

Apparatus in accordance with this invention com rises a carbureter or vessel for containing ydrocarbon and having an inlet ada ted to deliver the air to be carbureted to t e interior of a hollow float or a chamber formed in one with or carried by a float, whence it issues through an outlet or a series of outlets below or about the surface of the hydrocarbon, means for varying the immersed depth of the outlet or outlets below the surface of the hydrocarbon, and hence the richness of the resultant carbureted air, as required, and means for maintaining any desired level of hydrocarbon wi thin the carbureter.

I will further describe my invention-with reference to the accompanying drawings, wherein Figure 1 is a sectional elevation, and Fig.2 a plan of same on the line Y Y.

vIn the drawings and in the following de-v scription like marks of reference indicate like parts.

.A carbureter made in accordance with this invention comprises a vessel a, suitably supplied with hydrocarbon and closed by a cover 0, provided with an inlet-pipe d and an outlet pipe or pipes e. The inlet-pipe (I de ends and is sealed by mercury or some ot er heavy liquid between a' air of concentric tubes 9, the inner of whic g, communicates wit a chamber 72., formed in one with or carried by a hollow or other suitable float 7'.

1) is a depending flange which forms around the float 1' an annular outlet from the chamber h. The lower. portion of the depending flange v is provided with rings or rows of graduated perforations to, through which the air from the chamber h can ass in addition to passing below the edge of t e flange. The perforations w are so arranged that increased pressure within the chamber increases the area of liquid upon which the air acts.

The supply of hydrocarbon to the carbug, of the concentric tubes reter is controlled by a float ac, arranged in a chamber or vessel y, communicating by a passage or opening 2 with the carbureter or vessel a, said float :0 being adapted to open a valve 2 when the level of the hydrocarbon within the carburetor a and chamber y has fallen to a predetermined height by means of a rod 3 and connection 4 to admit more hydrocarbon from the supply-pipe 5 toa cup 6, whence it is delivered to the carbureter a by a perforated pi e 7. The pipe 7 is preferably arranged spira fashion within the carbureter a, so that the hydrocarbon is evenly distributed within same, and the float a: is adjustable on the rod 3 by a nut 8 or otherwise conthe same can be varied as desired. The depth of the edge of the flange v and the perforations to below the hydrocarbon may be regulated by varying the quantity of mencury or other liquid between the flanges f bureting air for lighting, heatin or other purposes. When used in connectlon with an internal-combustion engine, the air to be carbureted will be induced through the inletpipe d by the suction-strokes of the engine. When used for carbureting air for lighting, heating, and similar urposes, the air to be carbureted may be in need or forced through the inlet-pipe d by a ump, blower, or the like and may be heated b a suitable heater before being admitted to t e inlet-pipe d. In

1 any case the operation is such that the air entering the inlet-pipe d flows down the inner,

ginto the chamber h at the end thereo whence it issues through the perforations w and below the edge of the depending flange 1;, depending below the surface of the hydrocarbon. The air then passes or bubbles up throu h the hydrocarbon, thereby becoming car ureted, and the resultant carbureted air is drawn off through the outlet or outlets e to the engine or for use directly it is made or stored in a suitable holder or holders for subsequent use, as required. It will now be observed that the float j, carrying the air-chamber h, rises and falls with the level of the hydrocarbon, and the outlet or outlets from the-chamber is or are thereby always reserved in fixed relation to the level of the ydrocarbon, and the air veniently, so that the level maintained by I issuing from said outlets always passes through a fixed head or depth of hydrocarbon and is thoroughly or evenly carbureted.

The surface of liquid between the inlet and the outlet or outlets of the chamber is considerably greater than the cross-sectional area of the inlet-pipe, and the cross-sectionalarea of the outlet or outlets is reater than the cross-sectionalarea oi the in et-pi-pe, thus the liquid can readily flow in and out of the outlet or outlets, and the air is not throttled, but is absorbed by the hydrocarbon and allowed to issue in the absorbed state and in bubbles, as distinguished from continuous streams.

In some cases the carbureted a r before passing to the outlet or outlets e may be caused to pass through a filter 12, composed of flannel or other suitable material 13, arranged between fine gauze 14 14 for absorbing any moisture in the carbureted air and float, a casing around said float forming a chamber, said concentric tubes forming a uid seal and telescopic connection between 1 the depending inletpipe" and said chamber, said casing being rovided with holes at different levels all be ow the normal level of the hydrocarbon, the total area of said holes increasing at each successive lower level.

The improved carbureting ap aratus comprising the combination of a vesse adapted to hold liquid hydrocarbon, concentric tubes through which the air to be carbureted passes to the hydrocarbon, an inletepi e depending between said concentric tu es, a

float, a oasingaround said float formin a chamber, said concentric tubes forminga iquid seal and telescopic connection between the depending inlet-pipe and said chamber, said casing bein rovided with holes at different levels all be ow the normal level of the hydrocarbon/the area of liquid in the chamber being greater than the cross-sectional area of said inlet-pipe.

In witness whereof I have hereunto si ned my name in the presence of two subscri ing witnesses.
