STATES HUGH L. MGAVOY, OFVBALTIMORE, ASSIGNOR OF THREE-FOURTHS OF HIS RIGHT TO JAMES FRYER, OF BALTIMORE COUNTY, MARYLAND.

VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 231,075, dated August 10, 1880.

Application filed March 17, 1880. (No model.)

To all whom it may concern Be it known that I, HUGH L. MoAvoY, of the city of Baltimore and State of Maryland, have invented a new and useful Improvement in Vapor-Burners, of which the following is a a vertical section of all parts of the burner eX- cept the tube. Fig. 2 is a front view of the burner. Fig. 3 is a side or transverse view of I5 same. Fig. el is a top view. Fig. 5 isa vertical section of the burner-tube. Fig. 6 is a perspective of the adjustable sleeve for regulating the supply ot air. Fig. 7 is a cross-sec` tion through the dotted line in Fig. l. zo The letter A designates the oil-supply pipe; a, the passage leading to the needle-valve b. The casin g ofthe passage constitutes the heater a2, and is bored out by a tool entering at the points now shown closed by the screw-plugs c. d is the receptacle for the oil, which is burned at first to heatlup the parts to get it in condition to generate vapor.

` E designates a burner-tube holder, open at both ends, and F the burnertube, provided 3o with a flange, e, which rests on the top edge of the tube-holder and serves to support the burner, the tube of which depends withiuthe holder. The upper part of the burner-tube immediately below the flange e has an enlarge- 3 5 ment,f, which is adapted to iit snugly within the holder, and the lower end of this tube is likewise adapted, by means of an enlargement, j", to fit the tubeholder, and the exterior ot' the burner-tube betweenthe two enlargements 4o is so much smaller than the casing of the holder that an annular space, g, is formed therein. (See Fig. l.) An opening, h, is provided in the small part ofthe burner-tube communicating from the vapor-passage i, extending through it, and a screw, le, is provided, which enters the passage t' and serves t0 lessen its capacity for the tlow of vapor. The opening in the lower end of the burner-tube is tlaring or funnel-shaped, as shown at n, Fig. 5, 5o and is immediately over the needle-valve or vapor-exit b', so that the vapor issuing there. from enters the passage t' ot' the burner-tube and carries with it an amount ot' atmospheric air,as will be readily understood. The amount of air which is thus intermingled with the vapor may be lessened by means of the adjustable sleeve I, which tits and is adapted to slide on the lower part, a', of the heater. B y raising this sleeve the space ,separating the vapor-exit b and the flaring opening n, is partly closed, 6o

and thereby the supply of air which can enter the opening u is lessened. As the sleeve incloses that part ot' the heater below the vaporexit, it serves to protect said part from the cooling action ot' the air, and thereby prevents 65 condensation ot' the vapor in its passage through it.

A hole, p, is on each side ot' the casing ofthe burner-tube holder', (see Figs. l and 7,) and through these holes vapor may escape from the 7o annular chambery, to produce a jet which will play on the side of the heater a2. Each side of the holder is provided with a wing, q, curved backward toward the heater to partly surround a hole, p, and serves to shield the heating-jet. A slot, u, is formed in the shield,through which thejet or llame may be seen from the front side.

By this construction the heat to maintain the generation of the vapor is applied below the burner F, and as the llame issuing therefrom 8o does not come in contact with any heating device the light is in no way interfered with.

lt will be observed that the burner has a central slot, s, of depth suiiicient to permit the flame to issue laterally, and on each side of said slot is another slot, t, oi' much less depth. These side slots increase the density of the tiame at the upper and central part, the three slots producing a larger flame.

Having described my invention, I claim and 9o desire to secure by Letters Patent ot the United Statesl. In a vapor-burner, the combination ofthe burner-tube holder E and the detachable burner-tube provided with ailange, c, to rest on the top edge of the holder, and having just below the flange and at its lower end an enlargement, each of size to it snugly within the holder and form between the enlargements an annular space, g, as set forth. roo

2. In combination with the Vert-ical heaterease a?, the tubular burner-tube holder E, having holes p for ythe heating-jet, and the shielding-Wings q, attached to the holder and curved backward to partly surround the holes7 as set forth.

3. 1n a Vapor-burner, the combination of the holder-ease E, having holes l) for the heatingjet, and a burner-tube Within the ease arranged to lit snugly at its upper and lower ends and form an annular space, g, and having an openin g, h, communicate from the vapor-passage fe'- Within the tube to the space g, as set forth.
