Specification forming part of Letters Patent No. 27,470, dated Mmm 1a, issn; Reissue Namens, dated go, asse.

To all tcho'm it may concern.

Be it known that I, F. S. PEASE, of Buli'alo, in the county of Erie and State of New York, have invented a new and improved apparatus for impregnating gas, die., with the vapors of hydrocarbon liquids; and l do hereby declare that the following is a full, clear, and exact description of the saaie, refereuce'being had to the accompanying drawings, forming a part of this specification, in which- Figure l represents a. longitudinal vertical section of this invention.v Fig. 2 is a horizontal section ofthe same, the line mx, Fig. 1,indicating the plane of section.

Similar letters of referencein bothv views indicate corresponding parts.

To enable those skilled in the art to make and use my invention, Inwill proceed to,` de- Scribe its construction and operation.

A represents a vessel or box', of sheet metal, wood, or any other suitable material, and of considerable height, so as to give room fora number of shallow pans, B, which are secured in the interior of the boxat certain distances one above thefother. These pans are itted into the box in such a manner that' between the ends ofthe pans and the side walls of the box spaces a are leftalternately on one and on the other side of said box andigpans, as

l clearly shown in the drawings. Thesespaces are covered over\by strips b, of wire-gauze or of perforated sheet metal, which extend from.,

the ends of the pans in a slightly-inclined y walls ofthe box. l

The upper part-of the boxA communicates by means of a pipe, G, with-the gasome terand a pipe, -D, extends from the bottom ofsaid box into the condenser E, which consists f ltwo concentric tubes, c drone inside the other, as clearly shown in Fig. 1. The inner tube, c, is of cylindrical form from one end to the other, andthe upper part of the tube d forms also a cylinderfwhich surrounds the inner tube, leavinga passage, e, for the .of the tube dis conical,

so that the passage@ increases in width asit approaches the communicatin-g pipe D,and a disk, f, of wiregauze or of perforated sheet metal, is slipped over the tube c in such a manner that the passage e Vis completely stopped up a short distance above the communicating tube D, and that all the gashas to passthrengh the perforations i spread the gas as it gas. The bottom part' in sind disk. 'The conical part of the tubeis cut open, so as to give access to the interior of said tube for. the purprse of cleaning -the same. v

The upper end of the condenser E is furnished with a pipe, F, which conducts the gas to the burners. The pipes U and F are com nected by a pipe, Gr, which is closed by estopcock', g,

' the pipe G, close over its point of connection with the box A. When the latter cock is closed vand the cock g is opened the gas as it colnes-from the gasometer passes directly to the burners without making its circuitthrough the apparatus ,L the cock his opened, the gashas to passthrough the bor A and throu gh the condenser E before it reaches the burners.

"'"Anyhydroearbon'iiquidisintroducedthrough"r on the top of the box A, and a sucient quantity of liquid is poured in to make the several pans overow. The surplus liquid is removed from the bottom of the box by a faucet, j. When the gasventers the top of thel box it strikes directly on the surface ot' the liquid in the upper pan, and it 'is forced through the strip of Wiregauze or of perforated sheet metal at the end of this pan, whereby it isslightly arrested andcaused to he evenly spread out on the sheet b, passing an' openin g, t',

throughthe same and strikingupon the sur.

face of theliquid in the pan belowfin theforin ot an even stratum or' current of the same width as the perforated plate b, and so on throng-beach plate and over each pan until the gas arrives at the bottom of the box, from which it ,passes through the condenser to the burners. The perforated plates thus serve to-check and advances; preventing one portion from movingfaster than the other and causing the. *gas to manner. The' use of perforated tnbesland de vices to steadyv and spread the dow-of gas is Kwell known, and is not claimed broadlyas my invention The combination of the gas-supply pipe C with the top of the apparatus, so

that the gas shall enter at the upperpart and y be forced downward, as shown, causes the gas to pass along over the enti-re surface of the pans. Thepressureorsuctionbeingdownward,

the gas Hows close'along the surf-.ice of the pans, whereas if the flow were upwardn this and another stop-cock, h, is secured to but if the cock g is closed and.l

be delivered in a steady v' as it emanates from the box A directly -gas is obstructed, and-from whence said -deposit cannot be removedwithout considerable apparatus it is obvious that the gas would pass close up 4against'. thebottom of the pans, while at the end of each pan, immediately below the perfora`tr--"r plates, there would be a chamber, into which. the gas would ascend and almost wholly escape contact with the liquid in that portion of the pan beneath said chamber; but by causing the gas to flow downward, as set forth, the vapor pours from the surface of one pan directly down upon thenext below, and so on through the; sieves. vBy passing the gas box A throughthe .condenser E, before it reaches the dischargepipe, any sudden decrease in the temperature causes thev less volatile partsof the gas to condense and to form a deposit on thebottom of the condenser, from whence it can easily b'e removed whereas-if the gas passes from the tothe disch arge-pipe a sudden decrease of the temperature causes a deposit 'in saidF pipe, whereby the free passage of the trouble. i

paratus can be used for carburetiug air as well as gas.

Having thus fully described vmy invention, what I claim as new, and desire to secure by Letters Patent, is` o l. The combination of the box A, one or more pans B, for containing hydrocarbon liquid, the supply-pipe C, at ornear the top, the exit-pipeD, at or near thebottom, and thecou- March, 1867.
