Beit known that l MAXMILJAN -srnnv a subject of the lnqni-or of Germany residing 1n the city, county, and State ci' New Yrk, have'invenled certain new and. useful lImprovements in Carburetcrs, oi' which the 'followiugis a' had to the `drawing accompanying ing part of the same.

vLon WEN- aiid form- My invention relates to apparatus for carparticularly cated by 1, and may buretlng air, and has for its chief object to provide a simple, compact, and inexpensive apparatus for carburcting air ior he at1ng and 1 l uminating purposes/for the operation of 15 explosion enginesv etc.

The outer casing of the apparatus is indi- The casing isprovidedwith a cover or closure war through the `2, preferably removable 'to afford access" to the interior ofthe apparatus, and making an air-tight fit with the casing. i Inside the casing, and near the wall of the same, is a circu-` lar series of carbureting cylinders or re retin cylinders 3. These discharge pipes or '|50 -nozz es may be openor closed at their bottoms, but are provided with lateral perfora- -tions or air outlets, as 7., in annular series around the pipes and increasing in size, from speciiication, reference bring.

The latter extends downward to al point plane of the first orfu permost row ol' apertures 7 in the -disc large pipes (i, and leads out through the cover 2 to the point ofutilization or to a age tank or holder, not shown. AThe central chamber 9 and the carbureting chambers' are `substantially filled with materialvhaving great liquid-absorbent power, as for example sponge, which is the best material of whic I am at the From t 1e `foregoing the operation o the (,arbureter will be readily understood.

The liquid being at the same heig it in the ipes themselves, the apertures below the first row are ressure necessary to carry lthe air through tllie ap only moderate, the liquid w11 not be forced out oi the pipes, but the air will escape through the uppermost row of erforations into the mass of sponge which), althQti h thoroughly wet with the liquid is not su merged therein. The air escaping fromthe outlet apertures in the ,dischar e pi es, is brought into intimate contact wit? and picks u 'lhis vapor-gearing air porous sides of the'cham a gage-glass 15 ers or.l cylin ers 3,

As the liquid held by the lSpongesI outer casing the vapor-laden air passes above the liquid level is evaporated, more I liquidl issupplied by capillary action, thus slowly lowering the liquid level llu'ntil the.

. second row of apertures is exposed. At the saine time, the uppermost'portion of the mass of spon es becomes less wet by reason i escaped only through the uppermost row of v vapor. 4Fiirt errnore, the tot therefore 'might notl But the second rowbeingnowopened, an be# ing as close to the liqi. `1 level as the iirst row.

of the fact t at the capillary action is not sufiicient to keep that part of the filling as Wet'as the part adjacent to the liquid level, as will be readily understood. Hence if air perforations it wou d not come in contact with as much liquid as it had formerly, Vand pick up as much va' bi'.

Was formerly, the air issuing from said second roviT of apertures passes through ,the requisite quantity of saturated sponge and therefore ,ac uires the desired uantity of fil massI of sponge to be traversed by the air from the second row is greater than that traversed by the air from the iist row, and the greater resistance thus encountered necessitate an increase of air pressure to insure an equal ain ount of air from said second row, if the openings of the latter were of the saine size as those in the first. ertures of the second. row are larger than those of the iirst, and consequently permit an equivalent quantity of air to issue, though its velocity may be less. Of course-some air escapes through the upper row, but a `less amount than through the other, because of the greater outlet capacity of the latter, as will be readily understoodl This o eration goes on as described, the liquid fal ving and uncovering the rows of apertures in succession, which aperture increases in size downward, so that as the resistance to thev air increases the outlet capacity of the escape -o enings also increases, thus insuringthat t e greater portion of the air discharge from the pipes 6 will pass through those portions of the masses of s onge which lie nearest to the liquid and `w ich are thus thoroughly saturated therewith. In time, as the-liquid falls, the upper portions of the sponge in the chambers may and usually does become quite dr but, Jfor the reasons just mentioned, t e air is nevertheless carbureted to thedesired degree by' the wet sponge near the av'e become satu-` by the air would.

But the ap-l liquid: This operation ees on continuou'sly solong as the supp y of air is maintained through the pipe 8 and any liquid hydrocarbon remains in t The sup ly of hydrocarbon may replenis ed from timelto time, as

Extending the outlet pipe 12 the mass of sponge in the' chamber 9 but terminatingabove the liquid level is also an important feature. of the invention.l mischance back-hiring should be caused in the pipe 12 and the flame run back into the lcai'bureter,-the flame will be extinguished by the mass of Wetsponge around the end of the pipe and will not be communicated to the of course be required.
