4 Claims. 1
1 This invention relates to a stove designed primarily for use in heating and supplying the heat to the flues or pipes of tobacco curing barns.
An important object 'of the invention is to provide a burner of the liquid or gaseous fuel burning type, wherein the draft to the burner is downward, meansbeing provided to regulate the down draft to insure a steady and even heat, resulting in the desired curing temperature, during the various stages of tobacco curing.-
With theforegoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
Referring to the drawing:
Figure 1 is a sectional view through a tobacco curing barn, illustrating stoves constructedin accordance with the invention, as mounted therein. t
Figure 2 is a side elevational view of one of the stoves, a portion of the housing of the stove having been broken away, illustrating the interior construction of the stove.
Figure 3 is a plan view of the stove.
Figure 4 is a vertical sectional view through the stove, the housing thereof having been removed.
Figure 5 is an end elevational view of the stove.
Referring to the drawings in detail, the reference character 5 indicates the conventional type of tobacco curing barn, in which the pipes or flues 6 extend, the pipes or flues 6 communicating with the chimney 4, through which the smoke and products of combustion may becarried off from the barn.
As clearly shown in Figure 1 of the drawings, the inner ends of the pipes or flues 6 support the stoves 1, which form the essence of the present invention. Each of these stoves includes a hollow body portion 8 comprising a cylindrical casing 9, within which the burner Ill is mounted, the burner comprising the overflow pan l I, which is formed with an upstanding flange I 2 that constitutes the generating well or chamber I3. This generating well or chamber I3 is closed by means of the cap 14, which is provided with a circular line of openings I5, constituting the burner openings through which the flames from the well or chamber l3 pass upwardly. Fuel oil is fed into the generating well or chamber l3 through the oil feed pipe l6, which leads from a suitable source of fuel supply, not shown. The overflow pan II is provided with legs I! that rest on the bottom of the burner casing and support the burner in proper relation with respect to the casing at all times.
The burner casing or hollow body portion is formed with an opening of a, diameter to accommodate the draft. tube l8, which is provided with bars l9, extending across the ends thereof, the bars I!) having openings to accommodate the supporting rod 2|]. The supporting rod 20 hasits lower end tapered, as clearly shown by Figure 4 of the drawings, whereit rests in a depression 2 I formed. inthe plate l4, securing-the rod in an upright position. The rod-2t is formed with a threaded portion on which the adjusting nuts 22 are mounted, the nuts 22 gripping the bar I9 at the upper end thereof, at opposite sides of the bar, so that by adjusting these nuts 22, the draft tube may be raised or lowered to regulate the amount of draft to the burner, thereby regulating the heat of the burner and temperature of the barn. For example, when the draft tube I8 is elevated, a greater quantity of air will be admitted to the burner increasing the heat of the burner. By lowering the draft tube the heat may be reduced. Air is supplied to the draft tube through the pipes 23 that extend through the side walls of the barn to direct air to the tubes of the burners.
The reference character 24 indicates the overflow pipe adapted to return excessive oil which may overflow into the overflow pan II to the source of fuel oil supply.
From the foregoing it will be seen that I have provided oil burners for tobacco curing barns, wherein the adjustment of the fuel oil passing to the burners may be regulated for complete control of the temperature within the tobacco barn, thereby insuring the proper temperature during the various stages of tobacco curing.
Having thus described the invention, what is claimed is:
1. In an oil burning stove for drying tobacco, in combination, a casing, a circular body portion mounted within the casing and disposed in a horizontal plane, an annular flange rising from the marginal edge of the body portion providing an overflow pan, an upstanding central annular flange having external threads, disposed within the body portion and rising above the first-mentioned flange in spaced relation therewith, a cap threaded on the central flange providing a central generating chamber, said cap having a circular line of burner openings, a fuel feed pipe extending into the generating chamber, a vertical draft tube extending through the top of the casing, said draft tube having open ends, mounted above the generator chamber in spaced relation therewith, bars extending across the ends of the draft tube, a supporting rod having its lower end resting on the cap, said rod" extending through openings in the bars, and means for adjustably securing the rod to the bars regulating the draft tube with respect to the combustion chamber. 1
2. In an oil burning stove for drying tobacco, in
combination, means defining a combustion chamber having outlets for products of combus tion and heated air and an aperture in its top to receive a vertically disposed down draft tube, a burner plate upon the bottom of said chamber directly beneath said aperture, a downdraft" tube disposed vertically and extending upwardly from a point adjacent the burner plate through said aperture in the top of the combustion chamber means, saidtube having cross pieces therein, and a support for said down draft tube comprising a member resting upon said burner 25 plate and adjustably connected toone of said cross pieces.
3. The combination set forth in claim 2 in" which said support comprises: an elongated verticall'y disposed spindle, said spindle engaging said cross-pieces and having threaded engagement withone of said. cross pieces.
4. In an oil burning stove for drying tobacco, in combination, means defining a combustion chamber having outlets for products of combustion and heated air and an aperture in its :top thereof and accessible from the exterior of said chamber, whereby the height of the lower end of the tube relative to said burner plate may be adjusted and the combustion rate regu- Iated.
