SPECIFICATION forming part of Letters Patent No. 431,479, dated July 1, 1890.

Application filed February 28, 1889. SerialNo. 301,439. (No model.)

To @ZZ whom it may concern: Y i

Be it known that I, WILLIAM POWELL, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hydrocarbon-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 usethe same.

My invention relates to improvements in hydrocarbon-burners for crude oil, designed more especially for steam-generating purposes; and it consists in certain features of construction and in combination of parts hereinafter described, and pointed out in the claims. i

In the accompanying drawings, Figure lis an elevation. Fig. 2 is an elevation in section through the center of the burner. Fig.

3 is an enlarged plan of head e with fiutedv rod D in section.

A represents the easing, the form thereof being substantially a truncated cone open at top and bottom, the upper end thereof `daring out` ward, as shown. The cone has holes on the sides thereof for admitting the oil-supply pipe Gr and the steam-pipe F. B is an upright tube suspended centrally in the easing, this tube having lateral ears B', that are secured to lug a of the casing with ample stays between these two members A D.

Tube B has interal screw-thread I32 for receiving the lower and screw section of sleeve C. Below B2 tube B has a lateral screwthreaded arm for attaching the oil-pipe G. Above B2 a similar arm receives steam-pipe F. Sleeve C has an enlarged section C', that fits inside tube I3, to hold the sleeve centrally within the tube, this enlarged section having grooves or holes C2 for the passage of the steam. The sleeve next above the enlarged section terminates in an inverted-coneshaped head c, the upper end of this head being concave, as shown. The upper end of tube I3 is located a trifle below the upper end of the head e, and the upper face of head c is a triiie below the top of the casing. Head c is slightly larger in diameter than the internal diameter of tube I3, and when sleeve C is screwed down tight head c almost closes t-he end of tube B, but leaves an annular space between the head and tube, through which a thin annular sheet of steam escapes with great force, passing upward and flaring somewhat outward. In the bore of sleeve C operates with an easy fit a tluted rod D, the flutings thereof D serving as ducts for the free passage upward of the oil. The top portion of rod D is screw-threaded for deliector (l, with jam-nut d. The under side of deflector d has a flat surface corresponding in diameter with head c, and from thence upward delector (l curves outward, as shown at d2. The lower end of rod D has an enlarged dattened section D2, the same having a lateral slot D3 for receiving spindle E, the engaging section of the spindle being eccentric to the axis of the spindle, and by turning the latter rod D is elevated or depressed to separate detlector CZ from head c to give a free escape for the oil or to depress deiiector d to Iirni Contact with head o, as may be required.

Spindle E has an enlarged section E', constituting a bearing inside the oil-pipe, this enlarged section having grooves or holes e for the passage of the oil. Spindle E. passes out through a suitable stuffing-box located at the elbow of the oil-pipe, and the spindle is provided with ahand-wheel e', or with other appliance for turning the spindle on its axis.

Tube B at the bottom thereof is provided with a screw-threaded plug B3, by removing which rod D may be entered from below.

In operating the burner, with deliector d raised a trifle, a thin annular sheet of oil is projected laterally. rlhis sheet of oil is engaged, approximately at right angles th are with, bythe sheet of steam aforesaid, whereby the oil is atomized, the commingled oil and steam passing upward and at the same time being deiiected or liared outward by the overhanging section of dedeetor d. The force of the steam-jet draws a large amount of air upward inside the casing to support combustion, and the commingling vapors being ignited burn fiercely and dare out in a broad flame. This burner is designed more especially for steam-boilers, and in case of an old setting the burnerusually rests upon the gratebars, or in the absence of grates the burner is supported in like position by any suitable means that will leave the opening of the casing below unobstructed. In such position of lthe burner the flame directly impinges the boiler and envelopes the forward section of the boiler so far up as` the setting will admit, and from thence the flame is carried rear` ward by the draft, so that the entire heatingsurface of the boiler-shell is exposed thereto. In this respect this burner is a great improvement on burners that project a horiaontal flame, the latter variety requiring a Wall or other device for deecting the llame toward the boiler, by reason of which the forward section of the boiler is notimpinged by the ame.

Heretofore the one great difficulty in burning crude hydrocarbon oil has been to prevent the burner from clogging by reason of sediment in the oil. With my improved construction, by elevating head d by means of the eccentric the fiow of oil will usually wash out any sediment that has accumulated between the two parts c d, and if particles still adhere at the opening, by reversing the eccentric deiiector d may be brought to bear with such force as to crush such particles between the two heads, after which, by again elevating deflector d, the space will usually be cleared of all obstruction, all of which requires but a few moments of time.

What I claim is- 1. The combination, with a casing having an enlarged opening at its lower end and a smaller opening at its upper end, of a burner located within the casing with its upper end approximately in line with the upper end of said casing, the said burner consisting of au outer steam-chamber, an inner oil-pipe terminating in an outwardly-flaring head, and a 'defiector supported above and in close proximity to the flaring-head and the upper open end of the oil-pipe, the discharge-exit from the steam-chamber being below the discharge end of the oil-pipe, substantially as set forth.

2. The combination, with a casing open at both ends, the opening in the upper end being smaller in diameter than the opening in the lower end, of a burner consisting, essentially, of a steam-chamber, an oil-pipe located within said steam-chamber and provided on its outer surface with an outwardly-tapering head, the lat-ter being concave on its upper surface, the upper edge of head being slightly above the upper discharge end of the steamchamber, and a deflector located above and overlapping the discharge-outlets of the steam-chamber and oil-pipe, substantially as set forth.

3. The combination, with a conical casing open at both ends, of a burner located Within said casing and consisting of an oil-pipe provided on its outer surface at its upper end with an outwardly-tapering head, the latter being concave on its upper surface, a steamchamber surrounding the upper portion of the oil-pipe, with its open upper end slightly below the head of the oil-pipe, a deilector located above and extending beyond the discharge-opening in the steam-chamber and oilpipe, a rod located within the oil-pipe, and means for adjusting said deiiector, substantially as set forth.

In testimony whereof I sign this specification, in the presence of two Witnesses, this 29th day of December, 1888.
