KENNETH L. RILEY, OF LUDLOW, MASSACHUSETTS, ASSIGNOR TO RILE-EZONE BURNER AND MANUFACTURING COMPANY, OF LUDLOW, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

OIL BURNER.

To all whom t may concern:

Be it lrnown that I, KENNETH L. RILEY, a citizen of the United States, residing at Ludlow, in the county of Hampden, in the Commonwealth of Massachusetts, have invented certain new and useful Improvements in Oil Burners, of which the following is a specification.

lily invention consists in a new and useful improvement in oil burners and is designed to provide a vaporizing oil burner embodying a number of novel features to obviate certain disadvantages heretofore existing in burners of this type. One of the objects of this invention is to provide means whereby the heat absorbed by the material of the burner, and which in other oil burning devices of this type causes overheating and consequent internal ignition, may be utilized to pre-heat the air to be mixed with the vaporized eil. ln this way the surplus heat is taken from the material of the burner, allowing ruiming with a very high flame for long periods withoutoverheating, and at the same time, by mixing this superheated air with the oil vapor, a much more inflammable is produced, tending to economy in oil consumption. This object is attained by providing air passages in the body of the burner. forming integral parts thereof, especially passages through the outer walls of the burner, between the flame slots or holes, and generally any passage through the material of the burner through which air must pass to reach the vapor jet. Another object of this invention is to provide means in the vaporizer whereby carbon deposits are avoided, such as obstruct the vapor conduit and interfere with the operation of the device. This means comprises horizontal vaporizing tubes with slotted openings in their upper sides, a novel form of vapor screen, and a novel form of generator' tip.

lf have indicated in the details of construotion illustrated in the drawings filed herewith and hereinafter full described one speciic embodiment of my invention, but it .is to be distinctly understood that I do not consider my invention limited to said specitic embodiment but refer for its scope to the claims appended hereto.

Fig. 10 is a side elevation of a fragment of the side wall of the burner showing a modification of the flame openings.

Fig. 11 is a section on the line 11 11 of Fig. 10.

My improved burner comprises a casing 1 having side walls 2 in which are located 'llues 3 open at their lower ends t0 the atmosphere and connecting at their tops with air ducts el disposed above the walls v2 andvextending longitudinally of the casing 1, one on each side thereof. Transverse air ducts 5 connect the ducts 4 with the mixing chamber 6 above the distributing chamber 7 which is connected with the chamber 6 by the open'- ing 8. The mixing chamber 6 extends over only a portion of the distributing chamber 7 and has an end wall 9 in which is a centrally disposed orifice 10 through which the nozzle of the vaporizer is inserted into the mixing chamber 6, as presently described.

I provide in the walls 2 between the flu-es 3, and in the top 11 of the distributing chamber 7 flame slots 12. In the modication illustrated in Figs. 10 and 11, the flame openings are in the form of tubes 12a.

I provide a block 13 resting upon the top 11 and the tops of the air ducts 4, adjacent the orifice 10 in the wall 9 of the mixing chamber 6. Two vaporizing tubes 14; are mounted in this block 13 and the outer casing 15 of the burner and are so disposed as to be above the flame openings 12 in the top 11. ln each of these tubes 141 there is disposed a supply tube 16 having on its outer end a collar 17 abutting the outer end of the tube 14: and fastened thereto by a screw cap 18. A supply pipe 19 is connected with the tubes 16 to supply oil thereto. Each tube 16 is supplied on its upper side with a number' of slotted openings 20.

The block 13 is provided in its upper portion with a transverse passage 21 closed at its ends with screw caps 22. Each tube lei has in its top a slotted opening 23 affording communication between the tube 1li and the passage 21. The block 13 is also provided with a vertical bore 24 in comnuinication with the passage 21 and closed at its top by a screw cap 25. Positioned at the juncture ot' the passage 21 and the bore 211 is a removable thimble-shaped screen 26 so disw posed that the vapor passing through the passage 21 and the bore 24: must traverse twoy screen walls in its passage.

Mount-ed in the lower portion of the block 13 and extending into the mixing chamber 6 through the oritice 10 is the vapor tube 27 with which the bore 24 communicates. Upon the outer end of this tube 27 there is a stutling box 28 containing stui'ling 29. TWithin the outer end of the sutling box 28 there is threaded the valve stem casing 30 provided with slotted openings 31 and received through the end wall of the casing 1 and the wall 15 of the burner, and having its outer end closed by a cap 32 through which passes the valve stem 33 passing through the casing 30, stutting 29 and having its tip 34C in the reduced inner end of the vapor tube 27.

I provide a novel form of generator tip 35 screwed into the inner end of the vapor tube 27. The tip 35 is provided on its side adjacent the tube 27 with a transverse slit 36 communicating with an interior chamber 37. From this chamber 37, there is a circular vapor orifice 38 through which passes the vapor into the mixing chamber From the foregoing description of the parts of my device, its operation is 0bvious. Any suitable temporary heating agent is applied to the under side of the tubes 14 and the oil is permitted to flow through the pipe 19 and tubes 16. The heat causes the oil to vaporize and escape through the slotted openings 2O in the pipes 16. The vapor then passes from the tubes 1lithrough the slotted openings 23, and traverses the passage 21 and bore 24 to the vapor tube 27, passing through both the side and bottom walls of the screen 26. It is to be noted that by removing the caps 22 andthe cap both the passage 21 and the bor-e may be cleanech'and the screen removed and cleaned.

The i'low oi vapor from the tube 27 through the generator tip 35 into the mixing chamber 6 may be controlled by the valve stem 33 which is operable from outside of the burner. It is to be noted that the casing 30 screwed into the stutiing box 28 may be manipulated from outside of the burner and serves to compress the packing 29 to obviate leakage of the vapor from the tube 27. It is also to be noted that the openings 31 are provided in the casing 3() so that should any vapor penetrate through the packing 29 it would escape through these openings 31 into the burner and be consumed, thus preventing any leakage of the vapor to the atmosphere to cause a disagreeable odor.

rt is to be noted that the vapor from the ube 27 passesthrough the narrow slit 36 ot the tip 35 which extends across the full diameter ot the inner face ot the tip 35. rEhe width of this slit 36 is somewhat less than the diameter of the oriiice 38, thus tending to prevent the accumulation of any particles of carbon to clog the orifice 38 and impede the passage ot' the vapor therethrough.

rllhe vapor passing into the mixing chamber 6 commingles with the air supplied to the mixing chamber 6 through the tlues 3 and air ducts l and 5. The mixture of air and vapor passes through the opening 8 into the distributing chamber 7 whence the iniiamn i able mixture passes through the openings 12 and being ignited produces the iiames for the burner. The iaiames from the openings 12 in the top 11 serve to vaporize the oil in the tubes 14C.

lt is to be noted that the air supplied through the 'fines 3 tends to reduce the temperature ot' the walls 2 containing the iiues 3 and the air thus heated in its passage through the iiues 3 passes through the ducts 4 and 5 into the mixing chamber 6 at a high temperature thus creating a highly inflammable mixture with the oil vapor.

Having described my invention, what I claim is:

1. An oil burner having a mixing chamber, a distributing chamber, and flame openings trom said distributing chamber between the outer walls of ducts through which air is drawn to the mixing chamber.

2. In an oil burner, the combination of a casing; air Ltlues in the side walls ot' said casing; flame openings through the walls of said casing and between said air fines; a mixing chamber in said casing; and air ducts connecting said fines with said chamber.

3. An oil burner provided with a casing; iiues in the outer side walls ot said casing; flame openings in the walls between tiues; ain hanber; .longitudinal transverse passages connecting said fiues with said mixing chamber, and so arranged that air is drawn through said tlues and connecting passages into saidmixing chamber.

ln testimony whereof I atlix my signature.
