invention relates to oil stoves and more particularly to burners for Oll stoves.

It is a purpose of nyinvention to providea' new and improvedoil'vapor burner that is" provided with means for preventing flood;

ing of the same with oil, said means preterably compr sing a drain opening in said burner located at a low pointtherein, the

' floor or bottom of thechamber in the burner 7 other P ferablysloping continuously toward said drain opening.

It is afurther object ofmy inventionto provide means for igniting vapor passing from one of the groups of burner openings from the ignited vapor passing through angroup of burner openings; The burner openings mstoves of this character are ordinarily arranged in groups," said groups being spaced along the burner and be ng ordinarily 'difiicult to light one from the other, that is, the vapor orgas passing from one set of openings ordinarily'will not ignite the vapor or gas passing from the other set of openings A's ares'ult-it'i's frequent-ly necessary to ignite the'vapor Or gas passing from each set of openings'separately. In a stove in which thevapor that is used for fuel is generated by means of a fialne from the burner, it is frequently difiicult 'to light the vaporpassing from the groups of openings providing such a flame fo'rithe generator from the'otheropenings in the burner,

and itis a purposefofmy invention to provide meansfor accomplishing this. The ignition of the'gas or vapor passing from onegroup of openings in the burner from the gas or vapor passing from another group that has been previously ignited, is preferably accomplished by providing aslot in the burner extending from one set of openings to an adjoining set o f openings so i that the vapor passing out of the slot V-ill be ventionall such obvious changes and moditlie sc'ope of the claim.

"My improved stove comprises a casing 10 whichlis provided with suitable vent openings such as the .louvers 11 therein and ficationsof parts as would occur to-aperson;

skilled in this art and as would fall within:

which is provided with upwardlyextending sidef portions l2 and" a, back "wall portion 13. A burner 14 is suitahly'siipported ymeans of the casing" 1Q in :any desired manner, be-

lngprovided preferably with thefi'ange's l5 for supporting the same on the' casing. Said burner preferably comprises af hollow" body portio rthat has: aclo'sed rear wall16,

closed endi' w alls 1'7 and closed inclined hottoinf wall 18," the bottom *wall being in clined gradually fromjoneen'd walll? to the other end-wand? and incliningtrans versely-as shownat'19 toward the wall -por-. tio'nf20 whichis curved and which merges into) thejstraiglit wall portion'21 spacedfrom a partition 22 that extends from the i bottom walli1 8 to the'topwall23,the ex treme endportion of thepartitionf 22 being curved as indicated'at 24; A vapor chain her 25 and an air mixing chamber 26 are thus formed on the opposite sides of the partition-23. The top wall portion T23 of the burner between the wall 16, the partition 22 and a wall 27, is provided with a series of circularopenings 28 within which are seated the perforated disks 29 of refactory material said disks being provided with the closely spaced openings 30] therein communicating with the chamberv25. Theopenings 30 provide orifices for the passage of the vapor; out of the chamber 25 so thatrthe same may be ignitedand may heat the radiantvelements 3 1' located one over each of the "disks 29. Theinner face of the wall portion 23 "is provided with annular enlargements or ribs 32-surrounding each of the openings 28 to provide a larger bearing surface for the refractorydisks 28. The wall portion 27 is provided with similar openings 28' in which the-disks29" having the plurality of openings 30 therein are located, said disks being substantially "the same in construction as the disks 29. V

The body portion of the burner which is made of a casting, is preferably provided with. agtorwardly extending bracket member '33 which is hook like in form and which has a curved seat 34 for the tubular generator 35, the generator 35-being mounted at the opposite end thereof in an open ng 36 in the transversely extending wall portion 37, b

said generator opening into the ohamber 26. The generator is supplied with the oil or other liquid from which the combustible vapor is made, from a tank 38 which is provided with a valve 39 leading to the pipe 40 which connects with the generator 35, a

valve 41' being provided where said. pipe enters said generator tube. The pressure is applied to the liquid in the tank 38 in any desired .manner and any customary meansjfor this purpose may be employed.

- A hood 42 is provided extending from the top wall 23 toward the generator to thus direct theflame from the orifices 30 toward said vaporizer. The chamber 26 is provided with a side wall portion 43 which is connected with the :wall portion 37 and which is offset from the wall portion 21 to provide a relatively large air'inlet opening 44. The chamber 26 is further provided adjacent. the opening 44 with a bottom wall portion 45 which is. ofiset from the bottom wall portion 46 of the chamber 26 which in: elines downwardly toward the wall 37 from the transversely inclined portion 19 01 the bottom Wall 180i the chamber 25, the

. bottom wall 46 being slightly ofi'set adiae cent the inclined bottom wall 19 as will be clear from Fig. 5. Itwillalso be noted that the wall portion 29 extendsinwardly beyond the outer edge of the opening 44 a slight distance as indicated at 47.

1 Due to the depression of the bottom wall 46 below the bottom wall 18, a vertical wall portion .48 is provided extending downwardly from the walliportion 22 and said wall portion 48 is preferably provided with an internally threaded opening 49 which rechamber 25 or the chamber26, the same will not flood said chamber but will be drained ofii through the opening 49 into the tube 51 and thus to the receptacle 52. This is important as it prevents the filling of the chamber with liquid which would cause the stove otherwise to smoke. This is particularly important in connection with the radiant elements, as these arepart-icularly provided to avoid any odor or smoke, as any smoking of the burner due to liquid being burnt instead of vapor would tend to deposit smoke or carbon on the radiant elements, interfering with the proper action thereof. s

' lVhen the stove is put in operation the generating tube 35 is firstrheated by any suitable means ordinarily provided. "for this purpose to vaporize the oil or otherliquid producing a combustible vapor situated in the generator. The vapor thenpasses into the generatortube into the chamber 26 where it is mixed with air passing in through the opening 44. The vapor with air mixed with e the same then passes through the curved passage 57 leading into the chamber 25 and after reaching the chamber 25, passes out-through the openings 30- in the'disks 29 and 29. The vdisks provide groups ofopenings, the groupsbeing spaced from each other. To place the stoveiin operation-it has been necessary in devices otthis, character to light the gas passing through each disk 29 and each dick 29' separately to insure the lighting of all ofthe same, as the flame would not travel from one diskto the adjoining disk under ordinary circumstances and could not be relied'upon to do this. This difficulty has been increased due to the use of the radiant elements 31. I have accordingly'provided means for transferring the flame from one disk 29 to the next adjoining disk 29, comprising the slots 58, said slots extending through the-top wall 28 of the burner and communicating with the chamber; 25 so that the combustible vapor is passing through said slots-in close proximity to the flames above the disks 28, thus making it easy for the flame to travel iromone disk to another, thus insuring the substantially;instantaneous ignition of the entire burner at the same time. In order to make sure that the vapor passing from the disks 29 ,will. also be ignited, a slot 59 is provided that extends between a pair of the openings 28' adjacent a pair of said disks 29, and said slot 59 is connected with a slot 60 in the top wall 23 which, in turn, is connected with one of the slots 58. Thus the flame will travel from I A burner of the character described, ineluding a vapor chamber having an inclined bottom wall, a horizontally elongated mixing chamber, having an oppositely inclined 5 bottom wall, communicating at its shallow end with the deep end of the vapor chamber the top walls of the chambers extending in parallel planes, and, a drain conduit communicating with the deep end of the mixing chamber, the mixing chamber having an air intake port opening thereto between the points of communication of the mixing chamber with the vapor chamber and with the drain conduit.

In testimony whereof I affix mv signature.
