HYDROCARBON-BURNERf SPECIFICATION forming part of Letters Patent No. 4 13,316, dated December 23, 1890.

Application filed March 6, 1890. Serial No. 342,909. (No model.)

T0 to whom it may concern:

Be it known that I, RODERICK T. DAVIES, a citizen of the United States, residing at Southiugton, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification. T

My invention relates to improvements in hydrocarbon-burners; and the objects of my improvement are simplicity of construction and general efficiency.

In the accompanying drawings, Figure 1 is a front elevation or end view of my burner. Fig. 2 is a section thereof on line 5c 00 of Fig. 1. Fig. 3 is a side elevation of detached parts, and Fig. 4c is a plan view of the platespreader.

A designates the outer pipe or cylinder, the mouth 5 of which is enlarged so as to flare outwardly. The other end is screw-threaded or otherwise provided with suitable means of connecting it with a conduit B for furnishing a blast-as, for instance, from some suitable blower apparatus. Said outer pipe or cylinder is also provided with abracketC or other suitable means by which to attach it in position within the furnace or other place for use. Said pipe is also provided with two holes for the reception of screws 6 6, Fig. 2, by which to attach the inner pipe or cylinder D. This pipe or cylinder on its exterior is of less diameter than the interior of the outercylinder or pipe A, and it is provided upon one side with projections or bosses 7 7, in which the threaded holes for the screws 6 6 are formed, the ends of said bosses rest-ing upon the interior of the outer cylinder, whereby the inner cylinder is held in position with an annular space around it. This inner cylinder has a con tracted middle portion 8, from which it is enlarged in each direction, and on reachingthe ends is still further enlarged, so that the inside of the pipe flares outwardly at each end. An oil-supply pipe 9 passes througha hole in the outer cylinder or pipe into the inner cylinder, the opening in said pipe communicating with the interior of the inner cylinder. This pipe 9 may be supplied with oil by any ordinary connection from any proper source of supply. The inner pipe or cylinder D is slotted lengthwise on both sides from its ef- 'zontal position, as shown.

fluent end 14 to a point a little beyond the oil-pipe 9. The slots are preferably a little below the center, so that their upper edges will be substantially in a plane passing through the axis of the cylinders. \Vithin these slots I secure the plate-spreader E, the side edges of which rest in said slots, and

preferably a shank 10 or narrow portion enters the bore of the inner cylinderand extends a little beyond the ends of said slots to assist in holding the plate-spreader in place.-

end with diverging grooves 12 and with per-.

forations 13 within said diverging grooves. The effluent end 14 of the inner cylinder or tube is also serrated.

The burner is intended to occupy a hori- The air or other blast coming through the conduit B passes through the annular space on the outside of the inner cylinder or pipe D and inside of the outer cylinder or pipe A, and at the same time passes through the inner cylinder or pipe D on both sides of'the plate-spreader. Meanwhile the oil is flowing in through the pipe 9 and falls upon the plate-spreader E, and under the blast is forced outwardly along the groove 11 and grooves 12, some of the oil passing through the perforations 13, so that the oil on reaching the serrated end of the spreader is thrown from the end of the teeth on both sides and spread in all directions. Such portion of the oil as may flow along the interior of the inner cylinder or pipe D will be thrown from the serrated edge let at the effluent end, andv thus properly spread. Meanwhile the air-blast on the outside of the inner cylinder or pipe D, especially at the lower part of said pipe, will prevent the oil from falling down before it reaches the flame. By contracting the middle portion of the inner cylinder the combined oil and air is contracted in volume and given an increased speed as it reaches said contracted portion and is permitted to spread out after it. passes said point.

My burner is simple in construction, is easily managed, and efficiently spreads the oil so as to give effective combustion.

I claim as my invention- 1. The combination of an outer cylinderor pipe, an inner cylinder or pipe arranged within said outer cylinder or pipe with a surrounding annular space, a horizontal platespreader extending longitudinally within said inner cylinder for the reception of the oil, and an oil-supply with efiiuent end arranged to discharge upon the upper horizontal face of said spreader, substantially as described, and for the purpose specified.

2. The combination of an outer cylinder or pipe, an inner cylinder or pipe arranged therein and having a contracted middle portion, a flaring bore at each end, and a platespreaderarranged within said inner cylinder or pipe, substantially as described, and for the purpose specified.

3. In a hydrocarbonburner, the platesprcader E, having a serrated edge at its outer end and the central and diverging grooves, substantially as described, and for the pur pose specified.

4. In a hydrocarbon burner, the platespreader E, having a serrated edge at its outer end, and the central and diverging grooves and perforationsltl,substantially asdescribed and for the purpose specified.

5. In a hydrocarbon -burner, the plate spreader E, having a serrated ed ge at its outer end with its teeth bent alternately in opposite directions, and the central and diverging grooves, substantially as described, and for the purpose specified.

(5. In a hydrocarbon-burner, the combination of a pipe or cylinder 1), having flaring mouth and serrated edge at its eflluent end, and a plate-spreader within said tube, said spreader being also provided with a serrated edge, substantially as described, and for the purpose specified.

7. In a hydrocarbon-burner, the combination of an outer cylinder, an inner cylinder having a side projection or boss on one side with a threaded perforation, the projection being equal to the desired space between the inner wall of the outer and outer wall of the inner cylinder, and a screw extending through the outer cylinder or pipe into said side projection or boss, whereby the inner and outer cylinders maybe held in positiomwith an annular space between them, by means of only a single screw, substantially as described, and for the purpose specified.
