HYDROCARBON-BURNER.

Specification of Letters Patent.

' Patented Feb-.8, 1916.

Application filed March 5, 1912. Serial No; 681,680.

To all whom it may concern:

Be it known that I, JOHN PATON ROBERT- SON, a subject of the King of Great Britain,

having resided in the United States one year last past and having declared my intention of becoming a citizen thereof, now residing in the city and county of San Francisco,

State of California, have invented a new and useful Hydrocarbon-Burner, of which the following is a specification.

My invention relates to a novel construction of hydrocarbon burner which is adapted to be employed in conjunction with the lighter as well as the heavier grades of hydrocarbon and in connection with land, marine or any other kind of boiler furnaces and one of the principal objects of my invention is to devise a burner in conjunction with which novel means are employedfor regulating the strength or length of the flame and also to provide a novel burner tip and regulating device therefor which will produce a complete atomization of the oil.

With the above in view, my invention consists of a novel apparatus for burning light or heavy grades'of hydrocarbon or other oil, wherein the hydrocarbon preferably unmixed with air or other gases is preferably heated to the desired temperature, until it is discharged from the atomizer, novel means being provided for varying the length of the In carrying out my invention I do not desire to be limited to any particular degree of temperature to which I may heat the hydrocarbon, since I am aware that it is a common right to heat hydrocarbon to the desired degree by suitab e heating mechanism and to force the same under any desired pressure to a point of utilization.

To the above ends my invention consists of a novel construction of burner tip having a conical aperture with which is adapted to cooperate a novel construction of conical regulating valve, said valve having its forward portion guided and seated in a novel construction of disk having ports there-' through and tangential passages coacting with said ports and with said tip, the latter being preferably countersunk at its discharge end in order to insure proper combustion at the front of the furnace.

My invention further consists of a novel construction of burner tip in which a desired number of ports open at any desired angle into a valve controlled discharge pase sage. I

It further. consists of other novel features of construction, all as will be hereinafter. fully set forth. I

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me,-since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of WhlOh my invention consists can be variously arranged and organized and that my invention is notlimited to the precise arrangelnent and organization of these instrumentalities as herein shown and described.

F 1gure 1 represents a longitudinal sectional view of a hydrocarbon burner embodylng my invention. 'Fig. 2 represents a perspective view of the tip seen in Fig; 1 1n detachedposition: Fig. 8 represents-in detached position a plan view of the disk seenin Fig. 1. f 1

Similar numerals of reference indicatecorresponding parts in the figures.

Referrlngto the drawings, 1 designates a caslng having a chamber 2 therein, which latter communicates with any suitable source of supply for the heated hydrocarbon.

8 designates a packing nut secured preferably in threaded engagement with the easing 1 andhaving a chamber 4: forpacking or lubricating material, said packing nut 3 having a cap nut 5 secured thereto, which is provided withpacking; 6,the, valve stem 7 passing through said packing nut and being in threaded engagement therewith, as indicated'at 8, the exterior portion v9 of said valve stem carrying a handle or hand-wheel 10 thereon, which is secured thereon by the nut 11 and the pin 12 or other equivalent fastening devices.

13, designates calibrations or indicating .dataon the periphery of the hand-wheel 10, which are adapted to coact with the finger or pointer 14, whose free end terminates in proximity to said calibrations, whereby the amount of opening of the valve 15 can be at all times readily ascertained. A tube, 24, is secured at one end in the casing, l, and has the valve-stem extending axially through it. A body 28, is secured upon the other end of said tube and has an outwardly flaring chamber, 25. A disk, 17, has an axial bore,

16, in which the valve-stem is journaled, and a rearward extension, 18, and said disk covers the outwardly-flaring chamber 25. The front face of the disk is formed with an annular groove, 22, near its periphery, and ports, 19, are formed through the disk from said groove to the conical chamber 25. An annular recess, 21, is formed in the front face of the disk and surrounding its axial bore, and tangential grooves, 20, are formed in the front face of the disk, extending from the ports through the disk to the central recess. A burner tip, 26, has an annularflange, 27, and has its rear face bearing against the grooved and recessed front face of the disk, 17, and said tip has a conical axial seat, 28, for the conical valve 15 upon the valve-stem, which seat has an opening, 29, through the face of the tip. A coupling, 30, is internally screw-threaded to screw upon the externally threaded body 23 and has an inwardly projecting annular flange,

s31, engaging the annular flange upon the tip, so that the latter can be drawn against the disk and body, tightly securing the parts together.

When the parts are in assembled position, as will be seen from Fig. 1, it will be apparent that the valve rod or stem 7 has two bearings, one being the threaded bearing in the'nut3 while its forward bearing is in the opening 16 through the disk 17, theconical extremity 15 of the valve being located in the valve seat 28 wherefrom itwill be apparent that upon the rotation of the handle 10 the flow of the heated oil-through the pipe 24 and the orifice 29 can be regulated according to requirements, whereby the strength or length of the flame can be regulated or increased or diminished according to requirements. t will be apparent that by locating the threaded connection of the rod 7 in the position seen in Fig. 1, the same is removed as far as possible from the heat of the fire or flame and that there will be no liability of the same being injured thereby.

v By my novel arrangement of tip, disk, nut and-body portion for the sprayer or atoinizing device which constitutes the burner, the number of parts is reduced to a minimum and while my invention particularly relates to liquid fuel sprayers for burners in which the fuel is sprayed solely by the agency of pressure, I do not desire to be limited thereto in'every instance, since by my novel construction cold thick oil may be sprayed with the same efficiency as any of the lighter heated hydrocarbon products and I therefore do not desire to be limited in the use of my invention to any particular kind of hydrocarbon or boiler furnaces. By the employment of the finger or pointer in connection with the calibrations 13 the desired adjustment or position of the valve can be ascertained at all times.

It will now be apparent that l have do vised a novel and useful construction of a hydrocarbon burner which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

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

A liquid hydrocarbon burner, comprising I a tubular casing formed with an outwardly flaring chamber, a disk bearing upon the forward end of said casing and. having a rearward extension extending substantially through the flaring portion of said chamber, said disk having a central bore, a central annular recess in its outer face surrounding said bore, an annular groove near its periphery and ports through its bottom opening into said groove, a burner tip having an exterior flange at its inner end and seated with its inner face against said disk to cover said annular and tangential grooves and central recess, and provided with a conical central valve seat terminating in a diverging discharge port, a coupling adjustably connected with said casing and having an inwardly projecting flange engagin the flange of said tip, the discharge port of said tip being located outwardly of said coupling, and a conical valve siidable through said bore and cooperating with said conical central valve seat.
