IMPROVEMENTIN cARBu|=aEr|aRs-v Specification forming part of Letters Patent No. l 68,797. dated October `11, 1875 application filed f i October 5, 1875.

To all whom it may concern l Be it known than, WILLIAM D. SNOW, 0f- Brooklyn, in the countyV of Kings and State of New York, have invented certain new and usefullmprovements in Carbureters, of which the following is a specification:

This invention relates to certain new and useful improvements in apparatus for carburetlng air or gas, its object being to provide a convenient and ready means for inserting the endanger the apparatus and surrounding objects.

My invention consists vin a cylindrical, po-V lygonal, or other shaped vessel, provided with inlet-pipes for filling in the carburetiugfluid and for the admission of air or gas, and an exit-pipe leading to the burners for the escape of the carbureted air or gas, and containing a vessel or basket of wiregauze or other suitable foraminous material, contracted or conically-shaped toward the bottom, and provided with a series of horizontal partitions of wire-gauze or equivalent foraminous material, the spaces between which are illed with a packing of sponge or other brous material, as hereinafter more fully set forth and described.

The drawing represents a vertical sectional view of my improved apparatus for carbureting gas orv air. The letter A represents an outer casing of metal or other suitable material, of a cylindrical, polygonal, or other suitable shape, and provided with the pipes B and C, the pipe B for the admission of air or gas to becarbureted, and the pipe O for the escape of the carbureted air or gas on its way to the burners. Said pipes are provided with stop-cocks b and c, to control the ow of the` ed with the uncarbureted air or gas to any desired extent, if too richly carbureted.' The letter E represents a basket or basket-shaped vessel of wire-gauze or other foraminous material, provided with a series of wire-gauze or other foraminous horizontal partitions, c. The lower part of said basket is contracted, as shown, so as to leave an annular clear space around the bottom of the vessel A, for the collection of the hydrocarbon fluid employed for carbureting the air or gas. The spaces between the partitions are filled or packed with any suitable fibrous material, preferably with cut sponge, to absorb the carburetingliquid, and present an extended surface of the same to the action of the air or gas to be carbureted.

The carbureting-vessel is provided at any convenient point with an aperture or pipe for filling in the hydrocarbon liquid, and a suitable outlet at or near the bottom for drawing oi' any residue, when desired.

The operation of my invention will be readiv ly understood from the foregoing description. The spaces in the basket are properly lled with the sponge or other fibrous material and the basket placed in the vessel A, which is securely closed. The vessel A is then charged lwith the hydrocarbon liquid, consisting, as

usual, of the lighter varieties of naphtha, or the volatile constituents of petroleum. Thiswill be absorbed or taken up by the capillary attraction of the sponge, which will expose an extended evaporating-surface to "the action of the air or gas which is let in through the pipe B, thoroughly carbureting the same. Any surplus hydrocarbon collects in the annular space around the bottom of the basket, and, as the absorbed hydrocarbon is carried'off from the sponge by the air or gas, the surplus hydrocarbon is carried up by the capillary attraction, thus insuring the effective operation of the machine until the hydrocarbon liquid is entirely exhausted.

As thus constructed, an extremely simple, effective, andsafe apparatus is produced, in which the packing can be readily and conveniently inserted and supported in such manner as to prevent the matting or settling oi' the same, which would interfere with the effective working of the machine.

principle 'of the Davy safety-lamp, Will effect' ually prevent any communication of re to the apparatus, and thus insure perfect safety in its use.

The carbureters, as thus constructed, can be lIill'ed and transported from place to place with perfect safety, asthe bulk of the hydrocarbon is absorbed by the sponge, and in case of carelessness in properly securing the openings of the same, or of accidental breaks, very little, if any, of the liquid can escape, to en danger surrounding objects. This, it Will be seen, is an important advantage in innumerable instances, When portable carbureters are required.

Having thus described my invention, what I claim, and desireto secure by Letters Patent, 1s-

In an apparatus for carbureting air or gas, the combination, with the carbureting-vessel A, of the foraminous or wire-gauze basket E, provided With horizontal foraminous partitions for supporting the packing, and narrowed toward the bottom, so as to leave an annular space for the hydrocarbon liquid, the upper part being of such size as to ill or nearly fill the gas-chamber of the vessel A and prevent the collection of explosive gases, substantially as described'.

In testimony that I claim the foregoing, I have hereunto set my hand in the presence of the subscribing Witnesses.

W. D, SNOW.
