VAPOR-BURN ER.

SPECIFICATION forming part of Reissued Letters Patent No. 11,024, dated August 20, 1889. v

Original No. 399,183, dated March 5, 1889. Application for reissue filed May 29, 1889. Serial No.312,667.

To all whom it may concern,.-

Be it. known that I, CHARLES H. CHILDS, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Vapor-Burners; and I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it pertains to make and use the same.

My .invention relates to improvements in vapor-burners in which the burn er-cap for heating has a serrated lower edge and sits on a -iiange of the comminglingchamber, the latter havinga series of radial grooves made to mismatch the serrations of the cap, to the end t-hat 'the jets of iiame issuing from the burner are thus madeirregular in cross-section and thereby present a greater surface to the action of the air, and. lbetter results accrue in consequence of such irregular flame-j ets.

My invention also relates to the details of construction hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is an elevation partly in section. Fig. 2 is a bottom plan. Fig. 3 isa top plan view of the primary commingling-chamber, and Fig. et is an elevation with parts in section.

A represents the stan d-pipe, that screws into a boss b', the latter being' integral with the primary commingling-chamber B. This commingling chamber has the ordinary cupshaped formation and is provided with depending eduction.-tubes C and D. Ribs c and d on the under surface connect the said tubes with the boss l1', with retorts c and CZ formed in the ribs to connect internally the upper end of the stand-pipe to the respective eduction-tubes C and D. The primary commingling-chamber has a laterally-projecting boss E, cored to form the secondary commingling chamber E', from which leads the tube F,which connects with the lighting burner. (Not shown.) The chamber B has a cup-shaped depression BV, and in a central hole made through the bottom wall of such depression is placed an induction-tube H, the latter be` ing provided with a drip-hole h, for supplying the lighting-cup G. Primary commingling-cl1amber B terminates in a broad laterally-projecting flange B2, the upper surface of the flange forming a seat for the burnercap I. This cap has a depending rim, the lower edge of which is serrated, as shown at t', While the iiange B2 has a series of radial grooves Z9, that mismatch with the seri-ations of the cap by reason of there being a greater number of the one than of the other. De pending wings I of the cap hold the latter in a central position on the flange B2. Valve-arm Cscrews into the lower end of the eductiontube C, such valve-arm having a duct c2, that leads to the jet-orifice c3, the latter being reg ulated by the needle-valve cwhile the duct is closed by a hand-valve C2. Valve-arm D screws into the lower end of the eduction-tube D, this arm having a duct cl2, leading to the jet-orifice d3, the latter being regulated by a needle-valve d4, with hand-valve D2 for closing the duct. Jet-orifice o3 discharges into the induction-tube H for supplying the primary or heating burner, and ,jet-orifice cl3 discharges into an induction-tube e'for supplying a lighting-burner. The tube e screws into a threaded hole in the bottom Wall of boss E, by means of which the tube can be raised or loweredto bring the bottom end thereof in such juxtaposition with jet-orifice d3 as will regulate the supply of air to give the best results at the lighting-burner. An internal upwardly-proj ecting flange e prevents any dripping through inductiomtube e in case of condensed vapor returning to the secondary commingling-chamber E.

The orifice Where tube Fis inserted is usually of considerable size for convenience in coring chamber E', a bushing e2 being employed to reduce the orifice to the size of the pipe F, thus leaving considerable space belowr the pipe at the bottom of chamber E for receiving the condensed vapors. Boss E, being 4integra-l wi th the primary generator, is kept intensely heated by the heating-burlyier, and any liquid in chamber E had from condensation of vapors in pipe F is quickly revaporized.

The tube F leads iirst laterally and then upward to bring the lighting-burner to the desired location, usually some feet above the top of the stove and so far to one side as to be entirely out of the way. As aforesaid, the needle-valves c and d are set to regulate the discharge of the respective jet-orifices, and may be changed a trifle from time to time, if necessary, by the aid of a wrench. These j et- IOO orifices, therefore, are not enlarged or injured by closing of these valves, and the operator in starting the stove has no nice adjustment of valve to make, but, on the contrary, can turn valves C2 and D2 wide open.

Through inadvertence frequently valve C2 is closed to extinguish the heating-burner, leaving valve D2`wide open, in consequence of which there is much waste of gasoline as soon as the generator cools down. To avoid this I mount disks C3 and D3 on the respective valvestems, these disks being made to overlap each other and abut each other when the valves are open or closed, disk C3 being placed outside, as shown in Figs. l and 2. Vith this arrangement valve D2 must-be closed before it is possible to close valve C2. By reason of grooves b and serrations t', arranged as aforesaid, the jets of iiame issuing from the heating-burner, instead of being round, are thin and irregular in cross-section,thus exposing a great surface of iiame to the air, and this is found to add considerably to the heating capacity of the burner.

rlhe heating-burner is operated substantially the same as ordinary burners. The gasoline, being first admitted through jetorifice c3, strikes burner-cap I, and, falling back into the cup B', is discharged from thence through the orifice h and inductiontube II into the lighting-cup below. After the heatiugburner is in full operation, by means of valve D2 vapor may be discharged to the lighting-burner whenever it is needed.

What I claim isl. The combination, with the comminglingchamber having a laterally-projecting flange and a series of radial grooves in the top surface of the flange, of a burner-caphaving a series of notches or serrations in its under side, said burner-cap being adapted to rest on the flange of the said commiugling-chamber, substantially as set forth.

2. rlhe combination, with a comminglingchamber having a laterally-projecting flange with a series of grooves on the surface of the iian ge, substantially as indicated, of a burnercap having a depending rim with a` serrated lower edge, said serrations being made to mismatch the grooves of the generator-flan ge, and wings connected with the burner-cap for engaging the inner wail of the primary comniingling-chamber to hold the cap centrally, substantially as set forth.

The combination, with primary and secondary induction-tubes, of valve-arms having ducts and j et-orifices, hand-valves for opening and closing the ducts, and stops mounted on the respective valve-stems, said stops overlapping and abutting each other, with the valves in open or closedy position, substantially as set forth.

4. In a vapor-burner, in combination, the secondary generator integral with a primary generator, an eduction-tube connected with the secondary generator, such tube having an uprightarni for illuminating purposes, and a depression or pocket of the secondary generator for receiving the condensed vapor from such eduction-tube and for holding the same until revaporized, substantially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses, this 18th day of May, 1889.

CHARLES II. CHILDS.
