To all whom it may concern.-

Be it known that I, WILLIAM H. THORNLEY, a citizen of the United States,residing at Reading, in the county of Berks arid State of Pennsylvania, have invented certain new and usefulV 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 appertains to make and use the same. v

My invention relates to hydrocarbon-burners; and it consists in the novel construction and arrangement of its parts, as hereinafter described and claimed.

The object of my invention is to provide a burner of simple and cheap construction adapted to burn a certain quantity of hydrocarbon and at the same time consume a larger proportion of the combustible elements of air, the burner being so constructed as to properly mix the hydrocarbon and the air and throw the arne in any direction desired. The burner is provided with a water jacket or chamber which constitutes a chill and prevents the burner from being injured by the intense heat created. A pipe is provided having a suitablesprayer which thoroughly breaks up the particles of hydrocarbon, a means being also provided whereby the sprayer may be adjusted lengthwise and rotated, and this governs the intensity and character of the flame. The sprayers are not limited to any particular shape and for special purposes sprayers of particular construction may be provided.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure 1 is a longitudinal section of my improved hydrocarbon-burner. Fig. 2 is a side elevation of one form of sprayer. Fig. 3 is an end elevation thereof. Fig. 11 is an end elevation of' another form of sprayer. Fig. 5 is a perspective view of the burner, showing it as attached to a furnace-wall. Fig. 6 is a vertical transverse section of the burner-head, taken on the line 6 6, Fig. 1. Fig. 7 is a transverse section of the burner-head, taken on the line 7 7, Fig. 1.

The burner -comprises two castings, providing a burner-body 1 and burner-head 2. The burner-body 1' is formed integral with a tubular or hollow horizontal arm 1a, with atubular or hollow inclined arm 1b, having a flange 1c and merged Into the inclined arm la, and with a globular chamber 1d, having a supportingiiange 1e and constituting an air reservoir.

The burner-head 2 is formed integral with a rectangular inner shell 2"', with a rectangular outer shell 2b, with a haring or funnel-shaped end 2"', closing a water jacket or chamber 2d between the shells 2 2b at their inner end, and with a supporting-ange 2e, surrounding the shells at their outer end and having ears or lugs 2f. The inner shell 2L provides a commingling-chamber 2g.

3 is ay plate secured to a furnace-wall by bolts 3a and nuts 3b.

The supporting-flange 1e of the burner-body 1 has a central openinglh, coinciding with the outer end of the commingling-c'hamber 2g.

11 is a washer located between the supporting-anges le, and 2e and 1J are bolts whereby the flanges are fastened together.

The burner is secured to the furnace-plate 3 by means of bolts 3c, extending through the ears or lugs 2f of the supporting-flange 2e of' the burner-head 2, fastened by nuts 3d.

4 is a collar having a flange 4, connected to the iange 1c of the inclined arm 1b by means or' bolts 1b and nuts t. and pendent arm 1b is located a washer 4d.

4e is an air-pipe leading from a blower or compressed-air reservoir and connected by the collar 4. with the' inclined arm 1b.

This in-.

Between the collar 4 clined arm 1b extends at an angle of about forty-iive degrees `to the axis of the horizontal arm 1 and provides an air-inlet to the latter.

5 is a plug having a central opening and an angular head 5a and screw-threaded into the outer end of the horizontal arm la. 6 is a hydrocarbon-pipel loosely mounted in this plug 5 and extending through the horizontal arm 1x, through the globular chamber 1d, and through the commingling-charnber 2g to a position adjacent to the flaring or funnel-shaped end 2c` of the inner shell 2c of the burner-head 2. Located on and near tothe outer end of this pipe 6 is an externally-screw-threaded turn- IOO collar 7, having a nut 7, whereby it may be rotated, and its inner end engaging internal screw-threads in the plug 5. The space between the inner end of the turn-collar 7 and the inner end of the plug 5 constitutes a stuffing-box 8, in which a suitable packing is located. At the outer end of the pipe 6 is located a tap 9, having a reduced part 9, provided with an internal screw-thread receiving the screw-threaded outer end of the pipe 6. The reduced part 9L of the tap 9 is provided with an annular groove 9b, receiving the inner ends of radial pins or studs 10h, whereby the tap is connected with an internally-screwthreaded adjustable sleeve 10, which in turn is connected with the outer end of the turn-collar 7. The sleeve 10 has a nut 10, providing means whereby it may be rotated.

9c is an inner pipe-section connected to the tap 9 at its inner end and swiveled by a coupling 9d at its'outer end to an outer pipe-section 9e. 9E 'is a plug closing the outer end of the outer pipe-section 9e. 11a is a valve connecting the hydrocarbon-supply pipe 11 with the outer pipe-section 9e. Thus it will be understood that as the tap is rotated the pipe 6 will be turned, but the turning of the tap 9 will not move the pipe 6 longitudinally. When the sleeve 10 is rotated, its internal screwthread engages the screw-threaded turn-collar 7 and moves along the latter and turns on instead of with the tap, so that the latter is caused to advance or recede with the sleeve 10, and consequently moves the pipe 6, which is secured to the tap 9 longitudinally in or out, according to the direction in which the sleeve 10 is rotated; but the pipe 6 is not turned except when the tap is rotated within and not with the sleeve 10. Thus by the manipulation of the tap 9 the pipe 6 is rotated, and by the manipulation of the sleeve 10 the pipe 6 is moved lengthwise at the same time or at different times, as circumstances may require.

The tap 9 may be connected with the supply-pipe 11 by any suitable means which will permit of the pipe 6 being rotated by the tap 9. The part of the water-jacket 2I within the supporting-flange 2e is provided with an inlet-orice 14 at the bottom thereof and an outlet-orifice 15 at the top thereof, the inlet 14 being located at the lowest point of the water-jacket and the outlet 15 at the highest point thereof. Thus cold water is introduced into the waterjacket 2(l in the supportingiange 2e at the lowest point at one sideand is taken 0E from the water-jacket 2d in the supporting-flange 2e at the highest point at the opposite side. 16 is the pipe which conducts the water into the water-jacket 2, and 17 is the pipe that conducts the water from the water-jacket 2d.

The extreme flared inner end 2c of the burner-head 2 forms the point at which combustion takes place.

The pipe 6 extends well into the commingling-chamber 211F of the inner shell 2 and is provided at its inner end with the radial outlets 18 for the hydrocarbon, the outlets 18 being located just in rear of a sprayer 19. As heretofore stated, the sprayer 19 may be of any desired shape. Itis, however, made preferably approximately frusto-conical and has formed on its periphery a number of grooves 20. The said grooves may extend straight, as shown in Figs. 2 and 3, or they may be spirally inclined, as shown in Figs. 1 and 4. The sprayer as shown in Fig. 4: is circular, and will therefore throw an approximately circular flame, while the sprayer as shown in Figs. 2 and 3 is approximately elliptical and is so manipulated as to throw a flame of greater intensity from two of its sides than from the other two of its sides. The burnerbody 1 is further provided with a steam-inlet 21, which, as shown in Figs. 1 and 5, is closed by a suitable plug 21.

The operation of the burner is as follows: By opening the valve 11a in the supply-pipe 11 the hydrocarbon enters into the pipe 6 and passes out of the said pipe 6 at the radial outlets 18. At the same time air under pressure is admitted into the horizontal arm 1 through the pendent arm 1b and into the globular chamber 1d, the said air passing along commingling-chamber 2g blows the hydrocarbon against the sides of the comminglingchamber 2g and against the sprayer 19. By applying a light at the inner end 2c of the burner-head 2 the commingling gas and air are ignited. The air as it is blown through the grooves 2O of the sprayer 19 is finely divided and mixed with the hydrocarbon. Then by adjusting the pipe 6 as above described the intensity and the character of the fiame may be governed. Should it be found necessary or desirable to introduce live steam with the air, a steam-pipe can be connected with the steam-inlet 21.

Having thus described my invention,'the following is what I claim as new therein and desire to secure by Letters Patent:

1. A hydrocarbon burner comprising a burner-body, a burner-head, ahollow plug secured in the outer end of the burner-body, a screw-threaded collar secured in the plug, an adjustable sleeve secured to the collar,V a hydrocarbon-pipe extending through the sleeve supported in the plug and extending through the burner-body and into the burner-head, a tap secured to the outer end of the hydrocarbon-pipe, and means whereby the tap is connected with the sleeve so as to rotate therein or to be adj usted therewith.
