curved forni and are seated in the draft openings l5, best illustrate-d in Fig. l, with the inner edge of the tube resting on the ledge 17, the rear edge of the tube be ing provided with a lug or lip il), which.

engages beneath the floor of the unit l0,

or removing the bed plate units from the lire pot.. lt gives, furthermore, avery rigid closely fitting construction and preferably as at 20, the lower end of the tube 18 will; be flared downwardly to give an increased area and strenghen the construction against the strain on the lugs or .lips i9,

llhe said tubes i8 at their inner ends are of such formation as to nest with the other tubes, the end formation of the tubes in the present instance being shown as triangular,

since there are four tubes arranged at 90o from one another successively about the burner, but suoli design or formation of the tube ends may, of course, be varied to suit the needs of the particular assemblage of tubes. The inner ends oit the tubes are provided with -vvalls 2l which abut as shown. in Fig. Ll, so that while the nestedends of the y tubes deliver a substantially solid olumn of air, the draft currents coming through the tubes do not meet and comingle within the tubes or Within a central ohan'iber, as in sonie constructions now known to me, and the objectionable orosseurrents and baoldrafts due to any inequalities of currents Corning through the several tubes, are entirely eliminated. This results in a steady and uniform delivery of air from the nested. ends of the draft tubes.

The units lll, as stated, are of segmental forni, in the present disclosure, and when assembled provide an open center to reoeive an oil pan 22, the rim Hangs 22 of Wliieh engages over an .upwardly projecting ledge 23 extending from the. units l() so as to lool; the units together, The said, pan has at one side, an overflow pipe 24 which will prevent any flooding and overflow of the pan upon starting,- the burner, the said overflow pipe 24k delivering to any suitable receptacle or reservoir. Centrally of the pan 2i? is an open boss having in its top, a seat 26 to receive a perforated plate 27 which is preferably loosely mounted in: the seat 2li so that it may be readily' removed and having, as shown, perforations through which air may be fed to the burner or oil head,

The burner or oil head is preferably of the form shown and comprises a oonoavoconvex disk :2S having on its under .voneavo side a Central boss 2l), through n'hieh is a passage 30 which is threaded at its lower end and flares outwardly at its upper unthreaded end into the convex surface of the plate or t isla 2S. rlhe oil feed pipe 31 passes loosely through the disk 27 andiengages the threads l boss Q9 on the disk 28, the said feed pipe 3l; being secured and 'held in position in any suitable manner. ln order to maintain the oil distributing; disk or head 28 in proper relation to the dra-ft tubes, l preferably provioe a collar or sleeve 3l loosely surroun l- 'ing the oil feed pipe 3l, said collar 3l restingu at its lower end upon the plate 27 with itslupper end abutting and sustaining the lower endof the boss 29. These collars or sleeves 314 will be of proper length to maintain the oil distributor in its adjusted relationto the draft tube Vand Will support the plate 28 and the oil tube in position. i

By mounting the plate 27 loosely in the boss 25 with the oil tube 31 `traversing it loosely/,and by reason of the manner of assembling the the other elements as heretofore described, the matter of installing or taking down the burner is a simple one. The unit construction of bed plate; the separable oil pan with its associated distributor parts; and the knock-down nested draft tubes provide a burner which can be readily installed in furnaces or heating stoves, through the furnace or stove door Without the necessity of taking down or dismantling the furnace or stove proper and forthe` purposes of repair' and replacement, the present construetion. is a most convenient one.

ln order that the burner may be fitted to fire pots of varying sizes within reasonable limits, and to take care of any slight variations in the lire pot Wall, I may provide the units l0 wit/h adjustable plates 32 eonformingI to the obntour of the units, the plates in the present instance, conforming to the segmental sliape of the units. These plates 32 will be removably and adjustably secured by means of the slots 33 and the bolts 34 so that said plates may be extended or retracted Wi th resl'ieot to the circumference of the bed plate and the burner adjusted to varying'v sizes of pots. ln order to prevent any openings or ereviees appearing between the edges of the plates when they are expanded, l preferably lap the edges of the platos, as shown at 34, so that complete oirouznferential continuity of the' expansible plates is preserved, and no openings whiz-li would iu teri'ere with the up-draft through the lire pot are presented.

The action of the burner when assembled is in general, like the action of `burners of this type, with this important exreption, namely that the 11p-draft from below the grate, which stopped and dirooted by the rovering bed plate into and through the curved dratt tubes, is delivered by these draft tubes under the present construction, in a plurallli cgi
