IMPROVEMENT IN GAS-CARBURETING MACHINES.

Spec'ication forming part of Letters Patent Nor.il58,802, dated January 19, 1875; application Iiled Y December 4, 1874.

' tion:

The object of my invention is to facilitate the carbureting of common illuminating coalgas by devices which, without surchargin g the gas, shall permit its perfect impregnation with the vapor of a rich liquid hydrocarbon contained in a simple receiver; to facilitate the lling of the receiver to the proper level without excess; and to collect and automatically discharge the moisture of condensation in the eduction-pipe leading from the carbureter.

My said invention consists in distributing the gaswithin the receiver of the carbureting apparatus by means of two or more annular supply-chambers, formed about the inner wall of the receiver, iu such manner as to prevent any clogging of the induction-openings by the pressure ofthe absorbent material placed in the receiver, and arranged one above the other at proper intervals, and connected with the gas-main or induction-pipe by branch pipes controlled by cocks, so that when the receiver is first charged the gas may be admitted from the uppermost distributing-chamber alone, until the hydrocarbon held by the absorbent material above said distributing-chamber has been fully taken up, whereupon the gas may be admitted from the next lower distributin g-ch amber, thus avoidin g the surcharging of the gas consequent upon its passage through too large a body of the saturated absorbent material, and yet at the same time retaining the advantages attending the use of a large receiver for such material. y

In the accompanying drawing, A is a strong receiver, properly constructed of metal or other material, to resist the highest pressure of gas to be used. B is a feed-aperture, closed by a suitable plug or cock. U is a waste cock, placed at or near the bottom of the receiver. D D are distributing-chambers, constructed each of a flaring imperforate flange, c, arranged and secured to project downward at the tube.

an angle from the inner wall or surface of the receiver A, and combined with a second lower perforated iiange, f. placed beneath it, to project upward from the surface of the receiver at a suitable angle to strike against the edge of said upper imperforate iiange, e, to which it may be united. Each chamber D Dl encircles the receiver, as illustrated in the drawing. G is the induction, and H the eduction, pipe of the apparatus, for supplying gas to, and delivering it from, the carbureter. The induction-pipe is connected with each of the distributing-chambers D D by means of branch pipes G G', each controlled by suitable cocks z' i. K is a bent tube, one end of which is secured to the lowermost point of the eductionpipe H of the apparatus, and its other end carried nearly to the level of the lirst and left open. This bent tube K is made of such length as that, when iilled with water, the weight ot' water in the outer open arm of the tube will suffice to resist the pressure of gas within the pipe H, while at the same time the Water collecting in the inner end or arm of the tube will, in seeking its level, escape and be discharged automatically from said open end ot' M is a small tube inserted through the top of the receiver A, and which extends downward therein to a point below the top of the lowermost distributing-chamber, D, of the carbureter. To preventsaid lower end from clogging, the tube may be so placed as that it shall terminate within this lowermost chamber, as illustrated in the drawing. The upper outer end of the vent-tube M is closed by a suitable cock or plug. v

In the operation of this my improved carbureter the receiver A is first filled with sawdust, or other equivalent absorbent, cellular, or tibrous material. The peculiar formation and arrangement of the annular distributing. chambers D D will prevent this absorbent filling from ndin g its way from the receiver into said chambers. The receiver is then sn pplied with gasoline or other equivalent rich and light hydrocarbon oil, which is t0 be poured into the receiver through the feed-v aperture B until all escape ot' air or gas for this purpose) ceases, indicating that the liquid has attained the level of the lower end ot' said tube. This automatic indication of the proper level of the liquid supplied to the carbureter permits it to be iilled Wholly in the dark With entire exactness, which is a great convenience "where the apparatus is placed in cellars and like situations, and obviates the dangerous necessity of using a light. The trap-tube K being now filled with water, the carbureter is ready for use. Gas is admitted first into the uppermost chamber, D, so that it shall pass only through the upper stratum or layer of saturated material; but so soo'n as it is no longer sufficiently enriched by its admission through this channel,the cock controlling the passage into the next lower chamber, D, is opened, and thereafterinto the nextlower one (it` there be more than two) as the supply of hydrocarbon is gradually taken up, thus insuring more entire uniformity in the operation of carburetin g the gas, from the time the receiver is charged until it is exhausted, than has heretofore been attained Without very complicated devices. The gas, entering either chamber D, escapes therefrom under pressure through the perforations in the lower ange, f, and is thus evenly distributed into the receiver to permeate the saturated material therein. Passing through this material, the gas becomes charged and enriched by the vapor of the hydrocarbon, and is conducted away through the eductionpipe H, as described. All excess of moisture in the gas, which may condense in the pipe H, Will tind its way into the tube K, and be automatically discharged from its open end, an escape ot' the gas through the same channel being prevented by the superior gravity of the fluid column in the outer arm of the tube.

I claim'as my invention- The receiver A, provided with annular distributing-chambers D D, arranged about the sides ofthe receiver at different levels, in combination with the branch pipes G G of the induction-pipe G, substantially as and for the purpose herein set forth.

THOS. J. MARTIN.
