These which Letters Patent of the United States jaws are arc-shaped intermediate their eX have heretofore been granted to me. In tremities and extend to opposite sides of the United States Patent No. 568,956, issued to base of the burner and to the front thereof,"4

45 me October 6, 1896, for example, a channeled as shown, and are made to be closed against 95 base was shown in which the outer wall of the the openings or perforations of the outer wall outer vaporizing trough or channel was shown of the trough or to be opened away from said provided withaseries of perforations or open perforations at the Will of the operator. This ings therethrough below the foralninous Walls opening and closing of the jaws may be ef- 5o to admit air into said trough at the base of fected within the scope of Vmy invention by roo any suitable means. As shown, the base A is formed with a forwardly-projecting arm a7, which may loe united to the base in any suitable manner-as, for example, by bolts (z8-the outer end of said arm being preferably looped to form a guide portion, (indicated at a9,) and through which said guide portion is passed an operating-rod C2, made to reciprocate through the guide portion of said frame. On the inner end of the rod C2 is carried a slide C3, engaging both of the jaws C and C', the adjacent ends of said jaws being constructed with angular-shaped portions, (indicated at c2 and 03,) the construction and arrangement of the outer ends of said jaws and of said slide being such that when the slide is forcedvinward the jaws will be closed against the perforated outerwall of the channeled base A and so that when said slide is pulled outward said jaws will be opened or spread away from the said outer wall. To this end the slide may be formed with upwardly-projecting fingers, (indicated at c4and 05,) looped at their upper ends to embrace the upper edges ofthe adjacent. portions of said jaws. By so constructing the slide and the adjacent ends of' the jaws it will be apparent that the jaws will readily be opened and closed as said slide is reciprocated. The slide may be formed with a stop c6 to limit the inward movement. thereof, said stop also preferably engaging a perforated lip g of the base and effectually holding the jaws in closed position when the stop is engaged in said lip.

Above the walls of the channeled base having the channels 0l, and a are located foraminous walls, forming combustion-chambers D and D', the air-inlet a2 of the base opening into an inner air-chamber, (indicated at E,) while the air-inlet as opens into a corresponding air-chamber, (indicated at E.)

Upon the inner wall of the interior channel a. is located a foraminous wall F, which may be provided with a cap or topf, havingtherein a perforation f'. This wall is preferably kerfed and is provided on its interior with integral ribs f2. ThisY foraminou's wall F, it will be observed, is located between the combustion-chamber D and the air-chamber E and admits air therethrough into the combustion-chamber D. The outer wall of the combustion-chamber D is shown at G, and the in'- ner wall of the combustion chamber D' is shown at H.

J is a surrounding foraminous wall constituting the outer wall of the combustion-chamber D. These walls F, G, H, and J rest upon the upperedges of the walls forming the vaporizing troughs or channels of the base, as shown more particularlyin Fig. 2. Outside the surrounding Wall J is a drum K.

As shown in Figs. l, 2, and 8, the wall G is formed with an outwardly-projecting ange G/ at its upper end. Said wall is also formed with vertical integral ribs g on the outside thereof, and the flange G' is provided with a series of recesses (indicated at g) in its outer periphery. The wall H, as also shown in Figs. l, 2, and 7, is formed with an inwardly-projected flange H and with inwardly-projecting vertical ribs h, the ribs h at their upper ends fitted into the corresponding recesses g' in the iiange G. When the two walls are assembled, as indicated in Fig. l, t-heinner edge of the flange Hl is adjacent to the outer edge of the flange G. It will be apparent that as so constructed the walls about the air-chamber E and forming the adjacent fire-walls of the combustion-chambers D and D may each be separately removed from the base of the burner whenever it may be desired Without interfering with the companion wall, inasmuch as the ribs heXtend upward through the corresponding orifices g', so that either of said Walls may be removed and replaced independently of the other and without disturbing the other.

In Figs. 4:, 5, and 6 a modification in the construction of the walls about the air-chamber E is shown, the arrangement of the recesses and corresponding ribs being reversed. In this case the inner wall G is provided, as shown, with the outwardly-projecting flange G' and with 'outwardly-projecting ribs g. So, also, the outer wall H is formed with an inwardly-projecting fiange H; but in this modiication the inwardly-projecting flange H' is constructed with inwardly-opening recesses h', constructed to receive the corresponding vertical outwardly-projecting ribs g of the companion wall, said ribs g projecting upward ush with the upper-surface of the flange G and opening upward through the corre. sponding recesses h' in the flange H'.

In the construction shown in Figs. l,l 2, and 8 the liange G projects over the upper ends of the ribs g; but in this modified form of construction it is evident that either of the walls may be separately removed and replaced readily whenever desired without disturbing the companion wall.

The surrounding wall J (shown in detail in Fig. 9) is provided with an outwardly-pro` jectingange J and with vertical ribs j, said ange being perforated intermediate the upper ends of said ribs, as indicated at j. The flange J projects outwardly over the upper edge of the drum K.

The kerfs in the various foraminous walls are indicated at m. v

Where the perforations in the wall of the vaporizing-channel of the base are of a size to freely admit a sufficient amount of air to effect immediate combustion when the burner is first being lighted, said openings are found to admit too much air after the burner has become heated to secure good combustion. When the burner is in heated condition, it is obvious that the hydrocarbon admitted into the base of the feed-'pipe is quickly vaporized, either Within the adjacent end of the feed-pipe itself or upon its initial delivery into the base, and an excessive amount of air entering through the perforations in the channeled IOO IOS

IIO

base is found to hinder the free spread of the vapor throughout the vaporizingchannels,es pecially as the heat ofthe burner tends to draw in a current of air through said perforations. Under no fire, as when the burner is being lighted or heated, this diiculty is not met; but by my present invention this difficulty is effectually overcome.

What I claim as my invention is l. In a hydrocarbon-burner provided with a channeled base perforated on its periphery, jaws arranged to be opened and closed to open and close said perforations in the base.

2. In a hydrocarl'ion-burner provided with a channeled base perforated on its periphery, pivoted jaws arranged to open and close said perforations, and means to actuate said jaws.

3. In a hydrocarbon-burner, the combination with a channeled base perforated on its periphery, of jaws pivot-ally connect-ed with said base and extended about the periphery of the base, and means engaging the outer ends of said jaws to close and open said jaws to close and open said perforations.

4. In a hydrocarbon-burner, the combinaiou with a channeled base provided with perforations on its periphery, of jaws arranged to open and close said perforations, and a reci procatory slide engaging said jaws to actuate Mthe saine.

5. In a hydrocarbon-burner, provided with a base, two single separable foraminous walls above said base forming the opposite sides and top of an air-chamber, either one of said walls removable from the burner without disturbing the other.

6. In a hydrocarbon-burner, two adjacent foraminous walls, the one provided at its upper end with an outwardly-projecting ange, and the other provided at its upper extremity with an inner-projectingl iiange, one of said walls lprovided with vertical ribs and the fiange of the other of said walls with recesses to receive said ribs, and whereby one of said walls maybe removed from the burner without disturbing the companion wall.

7. In a hydrocarbon-bnrner, two adjacent foraminous walls, the inner wall formed with an outwardly-projecting flange at its upper end, and with vertical outwardly-projecting ribs, the outer wall formed with an inwardlyprojecting ange, and with inwardly-projecting vertical ribs, the ange of one of said walls formed with recesses to receive the ribs of the companion wall, and whereby either of combination therewith a surrounding drum,

said flan ge perforated intermediate the upper ends of said ribs, and resting upon the upper edge of said drum.

9. In a hydrocarbon-burner, two foraminous walls located adjacent the one to the other and forming a chamber therebetween, one of said walls provided with vertical ribs, and the other of said walls with a recessed flange at its upper end to receive the corresponding ribs, and whereby one of said walls may be removed from the burner Without disturbing the other.

10. In a hydrocarbon-burner, foraminous walls located adjacent the one to the other and forming a chamber therebetween, one of said walls constructed wit-h an inwardly-projecting ange at its upper end and with vertical ribs, the other of said walls constructed with vertical ribs, and an outwardly-projecting recessed auge at its upper end to receive the vertical ribs of the corresponding wall.

ll. In a hydrocarbon-burner, two separable foraminous walls forming an intermediate chamber, said walls at their upper ends provided with flanges projecting the one adjacent to the other whereby said intermediate chamber will be closed at its upper end when said walls are assembled, said Walls the one removable from the burner without disturbing the other.

In testimony whereof I sign this specification in the presence of two witnesses.
