1 Claim. (Cl. 126-93) This invention relates to a liquified gas burning tobacco curer.

An object of the invention is to provide a tobacco curer of this character, which is easy to operate, safe to use and since only vapors are burnt at the curer, no liquid reaches the burner, thus making the burners instantly adjustable as to the heat produced. With anon-varying flame, higher temperatures are produced in the barn, making a more eflicient operation of curing the tobacco.

With the above and other objects and advan" tages in view, the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawings in which:

Figure 1 is a side elevational view of an embodiment of the invention;

Figure 2 is an end elevational view;

Figure 3 is a vertical sectional view on the line 3-4! of the Figure 1;

Figure 4 is a longitudinal sectional view of Figure 1;

Figure 5 is a cross-sectional view on the line 5--5 of Figure 4;

Figure 6 is a sectional view of the control valve in half open position and Figure 7 is a sectional view of the control valve in. full open position.

Referring more in detail to the drawings, the tobacco curer embodying the invention is designated generally by the reference numeral 50, and comprises the end pieces H and i2 respectively, which are bent in a substantially U-shaped form to provide oppositely disposed side flanges l3 and I3 on end ll, and I4 and it on end 52. The forward edges of flanges l3 and it are provided with outwardly extending right angular flanges l5 and I5 while the forward edge of flanges Hi and it are provided with similar flanges l5 and it. The upper and lower ends of the flanges E3 and I3 are provided with outwardly extending right angular flanges El and ii, while the upper and lower ends of flanges M and M are provided with similar flanges i3 and i8, and the upper and lower ends of the end pieces I! and 82 are provided with outwardly extending right angular flanges l9 and 59' re spectively.

The upper ends of the end pieces have secured thereto, on the inner sides of the flanges it and I3, and i l and it, by welding or the like, the side plates 28 and 2!! respectively, and these plates have longitudinal inwardly extending right angular flanges 2! and 2! respectively, while at the lower ends, the end pieces have the downwardly curved baffle plate or windshield 22 secured thereto by means of the upstanding flanges 23 and 23 respectively. Extending longitudinally of the bafiie plate 22, along the medial line thereof, is the elongated slot 2 to furnish air to the tubular burner 25 which is capped at each end by caps 26 and provided with a plurality of burner apertures 2i. The burner 25 is supported longitudinally of the curer by means of brackets 28 and 28 respectively, which are provided with end flanges 29 and 29' respectively, which are secured by welding or the like to the side flanges it and i3 and M and M.

Interpos'ed in the center of the burner 25 is a control valve 30 which is connected by a pipe 3! to a fuel supply, not shown. The valve 343 is provided with ports 32, 33 and 34 respectively, so that, as shown in Figure 6, port 33 will communicate with one-half of the burner 25, and with the supply pipe 3!, so that only one-half of the burner is in use. In Figure 7, with ports 32 and 3 S communicating with the burner, and port 33 with pipe 3!, the entire burner is in use. The reverse of Figure 6 is also apparent since if port 34 is in communication with pipe 3!, port 33 will be in communication with the opposite half of the burner 25.

A heat spreader 35, which is substantially formed and shaped as the conventional peaked roof, is provided with vertical depending arms 36, which are provided in pairs at each end of the curer so that they can be secured to the end pieces H and !2 by fasteners 3?, and the heat spreader can be made adjustable as desired by providing a plurality of openings to receive the fasteners 31!.

Secured to the inner surface of the heat spreader 35 is a substantially triangular shaped hafiie providing a partial de d air s ace 39 between the spreader and the bafile, which prevents the discoloration of the tobacco during the curing thereof. Longitudinal cutouts Mi along the longitudinal edges of the baffle provide the feet H whereby the baffle is secured by welding to the spreader 35 below the inturned upper flanged ends d2 of the arms 35. The cutouts intermediate of the feet ll form a slight air space which permits a slight circulation of air into the space 39. Thus there is enough air seeping into the space 39 to reduce the temperature of the heat spreader sufficiently to prevent an excess of heat directly over the heating unit. An excess temperature would cause a setting of 3 the green color in the tips of the tobacco leaves hanging over the unit before the curing process has progressed far enough for the tobacco to reach the desired color.

The curer is made of sheet metal throughout,

'which may be rust-proofed or galvanized, and

any number of these units may be used in the barn as desired.

There has thus been provided a tobacco curer which, it is believed, will accomplish the objects of the invention, and it is believed that from the foregoing description, the construction and operation of the invention will be apparent to those skilled in the art.

It is also to be understood that changes in the minor details of construction, arrangement and combination of parts may be resorted to,

provided they fall within the spirit of the in- 4 header, a three-way valve positioned in the center of the said burner header and having a fuel supply pipe extended therefrom, a baffle carried by the extended ends of the end walls spaced below the header and extended upwardly from a point below the header to the said extensions of the end wall, said baflie having a longitudinally disposed opening therein positioned below the header, 2. superimposed hood triangular shaped in cross section and having inclined side and end walls spaced above the upper end of the casing, depending arms positioned in the ends of the hood and extended downwardly into the casing supporting the hood above the casing, and an inner bafiie positioned midway of the height of the hood extended from wall to wall of the hood providing a partial dead air space within the hood.
