IMPROVEMENT lN APPARATUS FOR CARBURETIN'G MR Ofi GASES" p i Specification forming part of Letters Patent No. 46,771, dated March 14, 1865; Reissue No. 3,124, dated september 15, 186e.

Tov all whom it mayeonoern: y

Bc it known that I, JOHN A. BnssE'rT, of Salem, in the county of Essex and State of Massachusetts, have invented a new and usei ful Improvement in Apparatus'for Carbureting Air'orA Gases; and I do hereby declare 'that the following is a full, clear, and exact descrlption'of the same, reference being had to the drawings accompanying this specification.

The nature of my invention consists in the arrangement and construction of a carburet` ing apparatus, by means of which the air to be carbureted is caused to come in contact with the hydrocarbon liquid in finely-divided streams, so that each particle of air may be brought into intimate contact with the hydrocarbon vapor; and in the .arrangement'of the carbureting-surfaces so that this operation is suc-y cessively repeated, each time .increasing the' surface, so that the air may be gradually charged with an increasing amount of vapor until it is saturated. l

It also consists in envelopingone or a seriesl It also consists in placing thecarbureting n apparatus in a gasholder tank, with a waterseal," independent of the hydrocarbon liquid. To enable others skilled in the art to make and use my invention, I -will proceed to describe the means'by which I have successfully carried it intoeifect. f'

In the drawing, Figure 1 is a sectional view, and Fig. 2 a plan, of the apparatus used.

Similar letters vof reference indicate like parts in both figures. .1 1 The" air to be impregnated with hydrocarbon vapor is, forced into the carbureter'by the l pump A, which consists of the dry meterused for .measuring gas, adapted to this purpose, and which may be actuated by any of the motors in use. From the pump A the air is forced, through the pipe B, into the carbureting-chamber G. A series of concentric daphragms or cylinders, D, madeof perforated tin or zinc plate;v or other suitable material, are arranged around the inlet-pipe B (the openingof which' is abovethe level of the' hydrocarbon liquid) at regulardistances apart.

These diaphragms are covered by a plate, E,

at the top, and attached to them, making a gas-tight joint at the top. These diaphragms are covered with a text-ile fabric, F, woven for this purpose, the filling of` which is made of large,- loose threads of, long fiber, having great capillary power. This fabric is stretched tight 'over the cylinders,.and ,the airpasses through them successively. 'The hydrocarbon lliquid G is maintained at a constant level in the chamber by means of a reservoir, H, which L is lled at the opening I, and which passes into the carbureter by meansV of the pipe J A stop-cock, K, is placed vin this pipe, and when the reservoir is to beflled this cock is shut. After it is full the cap I 'should be closed air-tight. The stop-cock K is then opened, in'and iill vthe c'arbureter up to 'and covering the opening, L, which communicates with a pipe reaching above the level of the liquid in the reservoir. When this opening is covered the supply will be stopped until, by the exhaustion of the liquid below the level of this opening, air is admitted to the reservoir, and it is again supplied, and thus a constant Alevel '-ismaintained.

I The'outer cylinder D of the series D is'not perforated, except near ,the bottom, wherethere is a ring of small openings, M, about a Aquarter of aninchbelow the level of the liquid; The airpasses through these openings below thelevelfof the liquid bubbling out into the chamber, thus compieting the-car bureting processu It then passes out at the outlet-pipe N to the burners.

i A constant pressure 1s maintained upon-the gas by the use of the holder O, which moves' in the -water seal P, and is guided by the frame R. f

The ris'e and fall of the holder are controlled by thcmercury-valve S, which-is attached, by

the lever and .cord T, to the rod on the top of and the hydrocarbon liquid will flow as holder. when th'hoider rises as highs is desired,the lever is raiscd, depressing the cap V, which throttles the supply of air until the holder is lowered by the use of the gas, when the lever drops, the valve opens, and thus a regular supply of air is .maintained in proportion to the amount used, and the holder is prevented from rising against the frame R, which would render. the light unsteady by varying the pressure, or the-lower edge would unseal, allowing an escape of gas.` e y The valve consists of an. annular'cup, U, filled with mercury., A cap, V, having the lower edge serrated, is inverted over the cup, and attached, by the rod, to lthe lever land cord. The arrows; showthe direction of fthe currents of air and gas. n

The object in viewin this invention is the regular, progressive, and uniform carburation of the air. It is entirely automatic in its action, the gas being made only as used.- As the air passes through the r'st of the series of cylinders it receives a very slight carburation. At the next cylinder the streams of air are again divided and strained.. This process is repeated, with a constantl'y-increasingsun *l face, until the air is thoroughly carbureted. It is obviousthat thespaces between the cyl inders may be entirelyllledsvvith a capillary material and .the same result attained.

tank, sovthat it may bev readily taken out for examination by removing the holder; and, by having a-separate sealfor the holder, a very small quantity of liquid is required when it is desirable to use glycem'ne, lor some other material not liable to freeze, when the apparatus is exposed to cold. l

Having thus described my invention, I shall' state my claim as follows: f 41. The general arrangement -and construction of the apparatus,consisting` of the several parts shown and 2.l The carburation of air or gases by the use of perforated plates or cylinders, .with the fibrousv material partially immersed in the hydrocarbon liquid, substantially in 4the manner as set forth andshown.

3. The automatic regulation of the air to be admitted to ythe holder and carbureter by means of a valve connected with, and open. ated by, the holder through the lever and cord, i

orv their equivalents ,when used forl this purpose, as shown and specied.

4.' .A carbureting device placed in the gaslholder tank, in the manner substantially as described.

5. A' carbiujeting device for enriching air or gases with the vapor of a volatile hydrocarbon, placed in a gas-holder tank, hay'ng a seal for the holder independent of the level of the hydrocarbon liquid y 6. The vcoinbinationof` a device for carbureting air or gases, using capillary materials, with the method of carbureting 'by forcing the airor gases through thehydroc'arbon.
