GASEOUS-FUEL BURNER.

, SPECIFICATION forming part of Letters Patent No. 757,395, dated April 12, 1904. Application filed July 17, 1903. Serial No. 165,968. (No 11101161.)

. To all whom it may concern:

Be it known that I, OSCAR FALKENWALDE, residing at Baltimore city, in the State of Maryland, have invented certain new and useful Improvements in Gaseous-Fuel Burners, of which the following is a specification.

My present invention seeks to provide certain improvements in that type of gaseousfuel burners disclosed in my copending application allowed April 21, 1903, Serial N 0. 153,628, and it primarily seeks to providefor readily adapting the form of burner shown in my application referred to for burning crude oils in a manner to obtain a maximum'heat from a minimum amount of fuel by aconstant mixture of fuel vapor and superheated steam and water, and also to prevent carbonization of the fuel within the burner.

In its more complete nature my present in vention embodies means for feedingv crude oil to the mixing-valve. and superheating steam by passing the same through the hot zone of the burner and injecting the same in its dry condition into the mixing-valve, whereby to force the crude oil under pressure through the injector-valve in an uninterrupted flow and without danger of its depositing within the valve or burner; and in its still more subordinate features this invention consists in certain details of construction and peculiar arrangement of parts, especially with relation to the burner-body and its support, whereby a simple I and effective means is provided for interchangeably attaching a generatlng means in the hot zone of the burner utilized for vaporiz ing the refined oils to adapt the burner for use as an ordinary domestic or cold-oil burner and whereby the said refined-oil generator can be conveniently detached and replaced by a similarly-constructed generator designed as steam superheater for cooperating with any wellknown type of mixing-valve to which crude oil can befed in a cold state, all of which will be hereinafter fully explained, and specifically pointed out in the appended claims, reference being had to the accompanying drawings, in Which- Figure 1 is a perspective view of my improved gaseous-fuel borner, the same being arranged for burning crude oil. Fig. 2 is a longitudinal section thereof. Fig. 3 is a similar view showing the same arranged as kerosene-oil burner. Fig. 4 is a horizontal section thereof on the line 4: 4 of Fig. 3. Fig. 5 is a perspective view of the bottom casting hereinafter referred to.

In my present construction the burner comprises a horizontally-disposed body, preferably ofcircular shape, adapted to detachably seatupon the base-casting 2, presently again referred to, and the said body 1 has a longitudinally-extending conical bore or flue 10, which tapers from the entrant to the exit end of the body, as clearly shown in Figs. 2 and 4:.

Z) 6 designate a series of transverse flues, disposed radially with respect to the center of the body 1 and which bisects the conical bore 10, and 3 designates a series of air-inlets, which extend through the bottom of the body and communicate with the central bore 1 at a point where the fiues 6 Z) join" therewith.

bore 10, to provide for a thorough mixing of theoil and gas and for discharging the flame in radial and vertical directions.

At the front and rear ends the top of the burner-body 1 is cast with vertical extensions or bridge-pieces 1, each of which is provided with a seat produced by-a slot at, that connects with the lateral recess a, and the recess a in one of the bridge-pieces is extended in the opposite direction to that of the recessa of the opposite bridge-piece,- whereby when the generating-chamber G is fitted in place the same can be firmly locked from pulling up out of the end seats, and to securely hold the said member G from lateral motion in the recesses a clamp-bolts w are fitted through the bridgepieces to engage the said member G in a manner clearly shown in the drawings.

By providing the bridge-pieces 1 with seats, as shown, it is obvious the generator G can be conveniently mounted on the burner-body or removed therefrom, such means of attaching the generator being especially designed to permit of interchangeably attaching a second generator G. i

The generator G includes an elbow g", to which is connected an ejector or needle valve 5, which when the generator G is used discharges into the entrant end of the bore 10, and the said generator G also includes a T- coupling 8, provided with a detachable screwplug 8 in the top and a screw-tap at the bottom to receive a pipe-section 9, with which joins a union-coupling 12, having a threaded bore to receive the oil-feed pipe F and the screw-plug 12 in the bottom, as shown.

' In practice the members G, 9, 12, and 8 are filled with a suitable fluid-absorbing packing to screen the fluid and effect a thorough distribution thereof.

The parts so far described when cooperatively joined provide for burning keroseneoil, which is vaporized as it passes through the generator Gr by reason of the members 8, 9, and 12 being disposed in the heat zone at the rear end of the burner-body and the member Gr within the heat zone at the top of the burner, the flames through the openings 3 in the said burner discharging up out each side and over said member G when the burner is in operation.

The bottom casting 2 in my construction is substantially the same as is shown in my other application referred to, except that it is of a circular shape to conform to the shape of the burner-body 1 and which includes lugs 2 2", that project inwardly to form rests to support the body 1 and are located sufliciently above the base of the casting a to provide for the free circulation of air under the burner l for feeding into the air-inlets 3, and the lugs 2 are also elevated sufiiciently so as not to close oh the concentrically-disposed channels 2, that communicate at the rear end with the collecting-pocket 2", formed in the base, and at the front end with a similar pocket formed in the forwardly-extending portion f located under the ejector-valve 5. The bottom casting 2 in my present construction also has a central longitudinal V-shaped channel 2 that connects with the two end pockets 2 and f and whose side walls have air-openings 2 2", as shown.

For burning crude or asphaltum oils I provide a second generator G, adapted to be detachably fitted in the bridge-seats on the top of the burner in place of the generator G, and the said generator G comprises a pipe-section 9, having a union-coupling g at one end with which connects a pendent member g that extends down in the heat zone at the rear end of construction of the burner-body and the means for sustaining the oil and the steam Vaporizers G and G my generator can be conveniently utilized as an ordinary kerosene-oil burner or for burning crude oils for furnaces, boilers, &c., where intense forced heat is required, without changing any of the parts of the burner-body and its supportingbase. that is required to change from one use to another is to interchange the burners G and G.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
