Application May- 27,1949pSei-ial No. 95,747
This invention relates to certain new and useful improvements in oil burners and has referonce, more particularly stated, to. onewhich is admirably well designedand: suited for emcient performance when. used inia. tobacco .dryingand curing barn, as a general rule, in combination with necessary stack and flue means: and several other hurnersofj'the same construction. 1
A primary object: of the. invention is to-structurally, functionally and otherwise improve upon drying and curing. burners which have" been devised by others for the same purposes by providing a novel construction, which, even though relatively small in size as burners go, is actually a. heavy duty appliance in that it draws inmois tened air from moist tobacco and, as a result, develops a good flame with resultant eiTec-tive heating and rapid tobacco drying. l i
Another object of the. invention is to provide a structure which is susceptible of ready and economical manufacture and sale and is such in overall construction thatit makes for more expedient assembling and installation and, thereafter, provides for the making of ready repairs and replacements. i
More specifically, novelty has to do with the specific construction of the burner unitv on the one hand and the complemental housing on the other hand, said unitv being singly and collectively novel.
In carrying out my aims I provide a one-piece casting with supporting legs, a channel forming an oil ring and an outstanding flange with an outer marginal lip providing an oil overflow and drainage trough.
Then, too, novelty is predicated upon a simple readily attachable and detachable cone with adapting lugs which cone functions as an efficient flame spreader What is more, novelty has to do with a triple part housing characterized by an annular base which sits on the floor and which supports an attachable air intake plate which latter part, in turn, serves to support a irusto-conicalhood which constitutes an efiective flue insert or fitting. .v.
Other objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.
In the drawings:
Figure 1 is a perspective view of a. tobacco barn-type oil burner constructed in accordance with my inventive ideas.
Figure 2 is a perspectiv view of the oil burner per se.
2 Claims. (ct-158. 91)
Figure 3 is .a. vertical sectional view on the line 3-3 of Figure 1 locking in the direction of the arrows. U
The burner properis denoted by the numeral '5. and this supportsthe name spreader 6 and said parts '5 and 6, when assembled, are jacketedwithin the confines of the triple-part housing.
The burner 5 is a one-piece casting and is characterized by an oil ring which takes the form of a channel whose innerwall is denoted at l and outer wall at 8. Projectinghorlzontally and radiating from the outer wall and in a planewith thebottom of the channelis a circular flange 9 having a marginal upstandinglip i0 defining an oil overflow and drainage trough. The supporting feet or legs are denoted by the numeral H.
The oil deliverypipe or line (which attaches to an oil drum) is denoted at V2 and the drainage pipe or line I3 and the firstipipe I2 connects with .the oil ring and the Second pipe [3 with. the oil overflow trough as brought out in Figure 3. Pipe l3 attaches, at its opposite end, with an oilsump (not shown). The conical air deflector dis of a basal diameter about equal to the diameter of the air flow. passage ll of the oil ring and the base of said cone is spaced above the upper edge of the wall 1 by way oi lugs l5 which telescope into the ring defined by the flange I and also serve to frictionally hold the cone in place and at the same time provide the air circulating space as illustrated in Figure 3. 5 The housing is of three-part construction an characterized by a base or annulus I6 whichsis of the approximate diameter shown in Figured and which surrounds and is spaced from the lip iii. The upper edge portion of the base or annulus I6 is rabbeted to provide a ledge l1 and this serves to seat, the outer marginal edge or periphery oi the annular air inlet collar or plate [81 The air inlet holes in the plate are denoted by the numeral 19. The inner peripheral edge portion of the plate has an upstanding endless shoul- "deror bead 20 defininga ledge 2| which seats the base of the truncated cone or hood 22. The
tive tobacco curing results.
openings IS! on a plane approximately even with the upper open top of the oil ring. Consequently, we have a conical deflector at the axial center of the flue adapter 22, an oil ring (7 and 8) of an outside diameter less than the diameter of the base of the flue adapter 22 and a trough forming flange 9 of an outside diameter greater than the diameter of the adapter 22 and of considerably less diameter than the outside diameter of the plate I 8. Thus, the parts are precision made for correct mechanical coaction with one an other when assembled as shown in the drawings, particularly Figure 3. As previously stated, several of these burners are used in ordinary sized tobacco barns and they collectively take in the moistened air from the correspondingly moist tobacco and insure the development of a high sweeping flame, the production of eflicient heat and rapid drying and consequent curing of the suspended tobacco. There are many and varied styles and types of tobacco curing burners and for this reason I find it unnecessary to dwell upon how these burners function to bring about effec- I am concerned primarily with the structural details and their relationship and my claims are presented accordingly.
When installing, be sure to level burner in or der to maintain a balanced flame around same.
This can best be done by turning oil control burner to warm up before turning control valve to a, higher heat stage. Never light the burner while it is hot, let it cool until the bare hand can be held on burner.
To raise the heat properly open oil control valves gradually allowing two or three hours for heat to reach the desired stage, each time temperature can be raised in either side of barn by raising controls separately. Y
Changes in shape, size, materials and rearrangement of details and parts may be resorted to in actual practice, so long as they'do not depart from the spirit of the invention or the scope of the appended claims, as is well understood.
Having described the invention, What is claimed as new is:
1. In a portable tobacco barn oil burner of the class described, a unitary burner casting embodying an annular channel circumscribing and forming an endless oil ring, the inner wall of said channel defining an unobstructed circular air circulating space, said channel having means whereby a fuel oil delivery pipe may be attached to the bottom of said channel, a circular horizontal imperforate flange integral with and on a plane with said bottom and radiating from the outer wall of the channel and having an upstanding outer marginal lip combining with said flange in defining a relatively shallow oil overflow and draining trough, supporting legs integral with, underlying and depending from said flange, an air deflector cone, the base of the latter being of a diameter slightly greater than the aforementioned air space and having basal lugs telescoping and fitting frictionally in contact with the inner wall of said channel, and separate knockdown housing means for said burner embodying a truncated conical flue adapter lined up with theburner, said flue adapter being of a basal diameter larger than said channel and less than the diameter of said flange, support means spaced radially from and surrounding said oil ring and trough, said means being of a height which terminates on a plane with the upper open end of said channel, and a flat plate between said support means and flue adapter, said plate being disposed in a plane with the upper open top of said channel.
2. In a portable tobacco barn oil burner or" the class shown and described, an oil burner embodying a' one-piece casting, the latter including an annular channel forming an open-top oil ring, said channel having inner and outer vertical walls, a-circular horizontal flange integral with and radiating from the outer wall of said Channel and having an upstanding marginal lip and defining an oil overflow and draining trough, supporting legs attached to and depending from said flange,-an-inverted air deflector cone, the latter having-basal lugs telescoping and fitting frictionally in contact with the upper edge portion of the inner wall of said channel, the base of said cone being spaced above said upper edge, a flat annular plate disposed in a horizontal plane approximatelyeven with the plane of the upper open side of said channel and overlying said trough in vertically spaced parallelism and having its outer marginal edge projecting beyond the corresponding marginal edge of said trough and being provided with air circulating holes, means supporting the outer peripheral edge of said plate in the stated plane, the inner peripheral edge of said plate being in spaced concentric relation in respect to the outer Wall of said channel and the upper surface of said inner edge being provided with an upstanding circular rib spaced radially outward from said inner peripheral edge and coacting with the latter in defining a ledge, anda truncated conical flue adapter having its broad basal end resting on said ledge and held in place on the latter by way of the encircling upstanding rib, said adapter surrounding said deflector cone in spaced concentric relationship and having its truncated end extending to a position well above the apex of said cone.
