l Claim. (Cl. 34--19l .The present invention relates to new and useful improvements in means for curing tobacco and has 'for its primary object to provide, in a manner as hereinafter set forth, an apparatus of this vcharacter embodying anovel construction, combination and arrangement of parts through the medium of which a constant flow of fresh, Aheated airthroughthe tobacco may be had.
Other objects of the invention are to provide a tobacco curing apparatus of the character described which will be comparatively simple in construction, strong, durable, highly eicient and reliable in use, compact and which may be manufactured and installed at lowcost.
and advantages of the invention will become apparent from a study of the following ,specification, taken in connection with the accompanying drawings wherein. like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a View principally in vertical longitudinal section through an embodiment of the apparatus.
Figure 2 is a view in horizontal section, taken substantially on the line 2-2 of Fig. l.
Figure 3 is a cross sectional view, taken substantially on the line 3-3 o f Fig. 1.
Figure 4 is a cross sectional view, taken stantially on the line 4-4 of Fig. 2.
Figure 5 is a view in vertical section through the upper portion of the ventilator.
Figure 6 is a, .horizontal sectional view, taken substantially on the line 6-6 of Fig. 1.
Figure 'I is a view principally in side elevation, showing a modification. A
Referring now to the drawings in detail, it will be seen that the reference numeral I designates a tobacco barn of .suitable dimensions having a peak roof 2. Installed in-the barn I, preferably adjacent one end thereof, is a furnace or other suitable heater 3 which is provided with an oil subfor the burner 4, said blower being located on the outside of the barn I.'
Extendinghorizontally adjacent the floor of the barn I andconnected to the upper portion of the furnace 3 is a flue 6. Branches 1. are connected to the ue 6 and merge with an outlet 8 which passes through one of the walls of the barn I.
Enclosing the furnace 3 are spaced inner and outer -jackets 9 and I0, respectively.A Communieating with the outer jacket I0 is a fresh air inlet conduit II which, as illustratedto advantage in Fig. 1 of the drawings, communicateswith the All ofthe foregoing and still further objects v atmosphere through the end of the barn I which is remote from the furnace 3. The conduit II is .provided with an enlarged intake end portion I2 .having mounted therein a blower ,I 3.
Communicating with the inner jacket 9 is a dis- 5' charge or return conduit Il which extends horizontally below the conduit I I in parallelism therewith. Also, the conduit Ilextends above the flue 6 in parallelism therewith. Communicating with the conduit Il are branches I5 having upturned 10 free end portions I6 on which spreaders I'I arev mounted. .A damper I8 is provided inthe conduit. I4 adjacent theinner jacket 9. The reference numeral I9 designates a damper inthe conduit- II. At a pointl diametrically 'opposite the con-[15 duits II and I4, the inner jacket 9 communicates with the outer jacket I0 through an openi 20. .Any suitablemeans maybe provided to permit access to be had to the burner 44.
Mounted longitudinally beneath the roof 2 of the barn I is a. Ventilating conduit 2l having connected thereto oppositely inclined intake branches 22. 'I'he Ventilating conduit 2| is further provided, at an intermediate point, with an upstanding outlet 23 which. extends through the roof 2 and which is provided with a damper 24.
It is thought that the operation of the invention will be readilyapparent from a consideration of t he foregoing. The'tobacco to be cured is hung inthe usual manner at the desired elevation 30 above the floor of the barn I; With the burner 4 in Operation, fresh air from the atmosphere is blown throughI the conduit Il into the outer jacket I0 and'in this manner said air is preheated. 'I'his air then enters the inner'jacket 9 through the opening 20 where it is brought to the desired .temperature and from which it enters the conduit yll. 'I'his heated air is then distributed substantially evenly in the lower portion of the barn/I through the discharge branches I5. 40
'36 is a damperin branchesY I5 used in securing an even temperature in the barnA I. After being discharged from the branches I5 the heated airows upwardly through the tobacco into the Ventilating conduit'2l from which it is returned 45 to the atmosphere through the outlet 23. As the conduit II lis located immediately above the V conduit Il, the temperature ofthe incoming fresh air will be raised before it enters` the outer jacket- I0. Also, the conduit II functions as a guard to 50 prevent inammable matter from falling on the hot air conduit Il. The construction and ar- Y rangement' of the flue 6 andthe branches 'I there' of is such that the heat from the exhausting productsw of combustion from the furnace 3 will be 55" y tion in which a suitable burner is provided. AA
iiue 26 is connected to one end of the furnace 25. Mounted on the furnace 25 is an elongated casing 21 of suitable metal having mounted 1on-l gitudinally therein a horizontal partition 28 providing intake and discharge passages 29 and 90, respectively. The intake passage 29 is provided with an enlarged, longitudinally projecting intake end portion 30. The partition 29 is spaced from one of the end walls of the lcasing 21., as at ll. to permit the air to enter the discharge passage 3l from the intake passage 29. Extending horizontally in opposite directions from the discharge passage 39 are branches 32 having upturned free end portions 33 provided with spreaders 3l. A
blower 25 is provided in the enlarged intake end `llloi the passage 29.
In operation, fresh air from the atmosphere enters the passage 29 of the casing 2T through the enlarged intake end portion 29 of said passage 29 and is preheated, This air then iiows back through the passage I9 where it is brought to the desired temperature and from which it is discharged into the barn through the branches 23. In addition to curing tobacco, the apparatus may also be used for drying fruits and vegetables.
It is believed that the many advantages of a to. bacco curing apparatus constructed in accordance with the present invention will be readily understood and although preferred embodiments of the invention are as illustrated and described, it is to be understood that furthermodications and changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.
What is claimed is:-
In a drying chamber, a horizontally arranged inlet pipe having one end in communication with the atmosphere. heating means i'or heating the air leaving said pipe, an outlet pipe for the heated air paralleling the first pipe and located under the same, branch pipes leading from the outlet pipe and having their outer ends extending upwardly, dampers in the branch pipes for controlling the flow of heated air therethrough, hoods.
covering the upper ends of said upwardly extending portions of the branch pipes for distributing the heated air through the chamber, an outlet pipe leading from the top ci' the chamber, pipes extending along the top of the chamber and leading into the outlet pipe.
