HYDROCARBON-BURNER.

To all whom 'it mayv concern:

Be it known that we, JOHN H. T. MILLS w and VIEGIL H. MILLS, citizens of the United States, residing at Hubbard, in the county of Hill and State of Texas, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the follow- 4, ing is a specification.

This invention relates to oil burners and `more particularlyto that class ofburners in which a jet of steam or air is employed for atomizing the fuel at the burner tip.

The object of the invention is to provide a burner of simple and durable construction,

capable of producing a maximum amount of heat with a minimum consumption of fuel. A further object 1s to provide means for blowing out any foreign deposits that may `lodge in the steam or air outlet at the burner tip, without the necessity of shutt-ing down the burner or in any manner .interfering with the operation thereof.

A further object is to provide means where- V `by the fuel supply pipe may be quickly detached from the rear end of the burnerso as to permit the fuel conductor to be readily `removed from the burner and cleaned when necessary.

l A further `object is to provide a burner having a relatively large opening or clearance at the tip thereof to assist in ato-mizing the oil, the outer end of the oil conductor being beveled and preferably extended slightly beyond the cap of the steam or air outlet :to prevent the oil from coming in contact therewith.

A further object is to provide means for centering the oil conductor within the casing, and means for adjusting the cap of the steam or air pipewith respect to the bevel end of the oil conductor so as to produce a narrow steam outlet and also to prevent back pressure of the steam on the liquid fuel.

4.the appended claims.

' For a full understanding of the invention Specification of Letters Patent.

Patented Sept. 26, 1911.

Application filed November 26, 1910. Serial No. 594,317.

and the merits thereof, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a longitudinal sectional view of a hydro-carbon burner constructed in accordance with our invention; Fig. 2 is a side elevation of the same; Fig. 3 is a top plan view; Fig. 4 is a transverse sectional view taken on the line 4-4 of Fig. 1; Fig. 5 is a detail perspective view of the pivotcd frame and locking bail detached; Fig. 6 is a detail vertical sectional view illustrating a modified form of the invention.

Corresponding and like parts are referred to in the following description and indicated in all the views of the' drawings by the same reference characters.

The improved oil burner forming the subject matter of the present invention coinprises a tubular member or casing 5 prefer'- ably cylindrical in shape, as shown, and having its inner end threaded for engagement .with 'the correspondingly threaded end of a coupling 6, the latter being provided with lmeans for connection with a steam or air pipe, indicated at 7. Disposed within the casing 5, is an oil conductor 8 having its outer end inclined or beveled at 9 and its inner end extended within and detachably secured to a sleeve 10, the exterior walls .of

the conductor 8 being spaced from the casing to form an intermediate air or steam chamber 11 which communicates with the supply pipe 7 and through which fluid from the pipe 7 is conducted to the burner tip for the purpose of atomizing the fuel.

Threaded in one end of thecoupling 6, is a collar or bushing 12 having its outer end provided with a flange 13 spaced from la corresponding flange formed on the coupling 6 to produce an intermediate seating groove 14. Disposed at the rear end of the sleeve 10, is a casting l5 having its rear end closed and provided with a depression or socket 16 and its front end reduced to form a nipple 17 extending within the sleeve 10, the side walls of the casting being provided with an opening to which is connected in any suitable manner a supply pipe 18, through which oil is conducted to the burner tip. Seated in the groove 14, is a ring 19 having secured to or formed integral therewith a transverse bar 20 and provided at its opposite ends with laterally extending lugs 21 on which is pivotally mounted a rocking frame 22. Extending vertically from the upper endl ,of the frame 22, is an operating lever 23, while a lug 24 depends from the bottom of the frame for connection with one end of a coil spring 25, the other end of which is secured in any suitable manner to a pin 26 carried by the coupling 6.

Arranged at the burner tip, is a cap 27 having` oppositely disposed perforated lugs 28 to permit the passage of connecting rods `29, the rear ends of said rods being formed with eyes 30 adapted to engage suitable trunnions 31 secured to the side walls of the frame 22, said rods being retained in position on the trunnions by cotter pins or similar fastening devices 32. The outer ends of the rods 29 are threaded for engagement with clamping nuts 33, one of which bears against each side of the adjacent lug 28. The cap 27 is provided with an opening to accommodate the conductor 8, while the interior walls of the opening in the cap are undercut or beveled at 34 to correspond to the inclination or bevel 9 of the conductor, thus to permit the discharge of steam or air under pressure at the burner tip, as before stated.

It will here be noted that the outer end of the conductor 8 is preferably of the same diameter as the inner end thereof, thus to `produce a relatively large opening or clearance at the burner tip and assist in atomizing the oil. 1t will also be noted that the beveled end 9 of the conductor preferably projects slightly beyond the outer face of the cap 27 to prevent the oil from coming in contact therewith and also to prevent back pressure of the steam on the fuel. Suitable pins 35 are threaded in the casing 5 and bear against the conductor 8 for the purpose of centering said conductor within the casing and producing a steam or air passage of uniform width around the beveled end of the oil conductor. Thus it will be seen that by moving the operating lever 23 in the direction of the cap 27, the latter may be spaced from the adjacent end of the casing 5 so that the steam or air from the pipe 7 may be utilized for blowing out or cleaning the burner thus to remove any foreign particles that may find lodgment at the burner tip without shutting down the burner or in any manner interfering with the operation thereof.

Extending laterally from the opposite sides of the ring 19, are pins 36 on which is pivotally mounted a yoke or bail 37, the latter being provided at its free end with a threaded opening 38 in which is mounted for rotation a clamping screw 39. The free end of the clamping screw 39 is pointed and adapted to enter the depression 16 in the casting 15 so that by rotating the screw 39 in the bail until the pointed terminal of said screw engages the recess 16, the casting 15 will be clamped within the sleeve 10. A suitable gasket 4() is preferably interposed vbetween the flange on the bushing 12 and a stop flange 39 on the sleeve 10 to prevent leakage. 1t will also be seen that by releasing the clamping screw 39 and swinging 'the bail 37 upwardly in the direction of theV lever' 23, the casting 15 may be det-ached from the sleeve'lO and the latter, together with the conductor 8, removed from the By having the conductor 8 A similar result may be Attention is here called to the fact that :the bail 37 is pivotally mounted on the ring 19, so that the casting 15 and its associated ,parts may be detached from the burner and fthe conductor withdrawn from the casing without affecting the operating lever 23 or cap 27.

A clamping nut 41 is preferably threaded Ion the clamping screw 39 so as to lock the 'screw against rotation after the latter has ,been adjusted to clamp the casting 15 in yposition on the rear end of the burner.

The cap 27 is preferably formed with a rearwardly extending sleeve 42 which projects within the Huid chamber 11 and forms 'a guide for the cap when the latter is adjusted laterally with respect to the casing either to effect the cleaning or blowing out ,of the burner or to regulate the width of 'the steam passage at the burnertip.

In F ig. 6 of the drawings, there is illustrated a modified form of the invention in `which the inner end of the fuel conductor 8 is threaded on a gland or bushing 43, the

construction and operation of the device ybeing otherwise similar to that shown in Fig. 1 of the drawings.
