Application filed March 7, 1910. 4Serial No. 547,709;

To all whom if. may concern:

Beit knovvn that I, EBENZER A. W.

'JrrrERii-:s, a citizen of the United States,

residing at llloicester, iii the county of'- lYorcester and Commonwealth of Massachusetts, have invented a new, and useful Im-g provenient in Conduits for Gas Fuel, .of ivliicli the following is a. specification, ac'

- companicd by drawings forming apart of 'vided with recesses the sain-e, in Which- F'gure 1 represents a central longitudinal `sect-ion. of a portion of a conduit vfor gas fuel embodying my invention. Fig. 2 is a transverse sectional vienT on line'9f-2, Fig. 1. Fig. 3 is a central longitudinal vienv showing a modified forni of construction. Fig. 4: is a detached sectional view of the 5 and 6 of the case, shown slightly separated. Fig. 5 is a top view of that part of the case shoivn at 6, Figs. Q and 4.

Similar reference characters refer to simi lar parts in the different figures.

The object of .my present -'nvention is to provide a conduit for gas fuel having means for the removal of soot, or other combustible material, which is liable to accumulate in the bottom of the conduit 'during the passage of gas fu'eltlierethrough, and I ac. complish this object by the construction and arrangement-s of parts as hereinafter de scribed and pointed out in the annexed claims.

Referring to the accompanying drawings, 1 denotes aconduit for gas fuel consisting, in the present instance, of acyliiidrical pipe suitably lined with brick, or similarniaterial, through which gas fuel is conducted 'in the direction of the arrow 2, Fig. 1. In-

serted Within Athe brick lining 3 'is a bcX or case, preferably ofA cast iron, inclosing a compressed air chamber 4. The box or case may be conveniently made, as shown in Figs. 1 and 2, in'ttvo parts and 6, said parts being slioirn opposing each other but slightly separated in Fig. et, and tlie'inner' ortion 6 being shoivn in top view iii Fig. The top side '7 of the part 6 is iverlapped by the top sideS of the part 5, but the upper surface of the overlapped side 7 is pro- 9 .extending entirely. across the side 7 and communicating with the interior air chamber 1. The outer ends i .of the recesses are Wider than the inner ends to be' expanded thin horizontal currents as they enterthe Ainterior of the con-- Specification of Letters Patent. vPeniged Sep-1;', 10, 1912i' duit.-A screw threaded-'opening is pro-l vided in .the outer side of the box to receive anv air pipe l0 4communicating with a common supp y a sourc of air supply under pressure. -The pipe. 1 1s preferabl 'extended theentire length of thel conduit -with branching air pipes communicating with' compressed-air boxes at frequent intervals in' the length of" the conduit.

A 'charge of compressed air is forced through the pipes l11 -and 10 into. t-lie 'air chamber 1' and nds. its escape through th'e recesses 9, as indicated by thea'rrows 12, 12, Fig. 1.

pipe 11, which is connected with livered through" the shallow recesses 9 in 5 thin sheets just Within the inner lining 3 o'f the conduitpart-ially loos'ens the accumulated mass of soot and furnishes a supply of oxygen which supports combustion and reduces the particlesof soot to a gaseous form. In Fig. 3 I 'have shown the 'conduit 1 having a similar. compressed lair box` 4 with supply pipes 10 and 11, but the box is inodified in the matter of its delivery recesses by having similar recesses 13, 14 for the discharge of compressed air from the box 4, the recesses 13 and'lt' opening in opposite directions, and causing t-he currentsof 'air to pass both in the direction of the arrow 15 and also i-n theopposite direction, as 'shown by the arrow4 1G, thereby increasing the area of combustion. It has heretofore been proposedto force' the soot forward with the moving gas ,in the conduit by means of amechanica'l 'agitation of the soot deposit ivhich sometimes results in a. mere change in the location of the deposit. By my improvement- I effect the combustion ofthe soot by a supply of oxygen tothe carboncontaiiied in the soot; t-he loosening of the soot facilitating the admixtiire of air and promoting the more cornfpleteconibiistion, reducing the solid parti'- eles of soot to a gaseous product which-is thenicarried forward byfthe current of gas flowing tlirougli'tlie conduit..

I claim,

1. The combination with a. conduit. for

gas fuel, of a shell heldin vthe wall ofthe conduit, having one of its'sides at an angle ivithrt'he axis of the conduit exposed and `provided With a narrow slit opening into-1141 the conduit in the plane of the inner surface of the Wall of the conduit, and means for supplying air under pressure to said shell.

2. The combination with a conduit for gas ueh of a shell, for compressed air in the Wall of the conduit-and having overlaping inner Walls with an intervening space 1n the plane of the inner surface of the conduit and communicating With,the interior.

of the shell, and means for supplying compressed air to said shell.

3; A conduit for gas fuel, comprising a pipe having a refractory lining, a metallic shell inclosing a chamber for compressed air contained Within said lining and having .overlapping innervv'alls provided with recesses between them, forming air passages from said air chamber to the interior of the conduit parallel with the inside of said u lining.

4. The combination with a conduit for gas fuel having a refractory Wall, of a metallic shell held Within said Wall and inclosing ,a

compressed air chamber, said shell having,

overlapping sides next the interior of said duit in a thin sheet adjacent to its inner surface. t

'Dated this third day of `March 1910.
