(Cl. 34--19l .The present invention relates to new and useful atmosphere through the end of the barn I which improvements in means for curing tobacco and is remote from the furnace 3. The conduit II is has 'for its primary object to provide, in a man .provided with an enlarged intake end >portion I2 .having mounted therein a blower ,I 3. . ner as hereinafter set forth, an apparatus of this Communicating with the inner jacket 9 is a dis- 5' 5 vcharacter embodying anovel construction, com . bination and arrangement of parts through- the medium of which a constant flow of fresh, Aheated air‘throughthe tobacco may be had. ' Other objects of the invention are to provide a 10 tobacco curing apparatus of the character de scribed which will be comparatively simple in con charge or return conduit Il which extends hori zontally below the conduit I I in parallelism there with. Also, the conduit Ilextends above the flue ' 6 in parallelism therewith. Communicating with the conduit Il are braïnches ‘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 All ofthe foregoing and still »further objects v II. At a pointl diametrically 'oppo‘site the con-[15 duits II and I4, the inner jacket ‘9 communicates ‘and advantages of the invention will become ap with the outer jacket I0 through an openi 20. parent from a study of the following ,specifica tion, taken in connection with the accompanying .Any suitablemeans maybe provided to permit drawings wherein. like characters of reference des _ access to be had to the burner 44.

A ‘ ' 'I'he Ventilating conduit 2| is further pro ing outlet 23 which. extends through the roof 2 25 and which is provided with a damper 24’. It is thought that the operation of the inven tion 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 ~« Figure 5 is a view in vertical section through the upper portion of the ventilator. substantially on the line 6-6 of Fig. 1. 22. . vided, at >an intermediate point, with an upstand . 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 pre heated. 'I'his air then enters the inner'jacket - 9 through the opening 20 where it is brought to Referring now to the drawings in detail, it will the desired .temperature an‘d from which it en be seen that the reference numeral I designates a tobacco barn of .suitable dimensions having a ters the conduit yll. , 'I'his heated air is then dis v40 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 . burner or coal stokerl. _ - Extendinghorizontally adjacent the floor of the barn I and- connected to the upper portion of the ' furnace 3 is a flue 6. 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 A blower 5 is provided l. discharged from the branches I5 the heated ’air for the burner 4, said blower being located on 45 the outside of the barn I.' tributed substantially evenly in the lower portion Branches 1. are connected to ñows 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 50 through one of the walls of the barn I. > Enclosing the furnace 3 are spaced inner and ` prevent inñammable matter from falling on the hot air conduit Il.

It will thus be seen that an apparatus has been provided whereby a constant ñow oi' fresh. warm air through the suspended tobacco in the barn l will be had. - ' , In the modification shown in Fig. 'l of the draw ings, the reference numeral 25 designates an elon gated furnace oi’ brick or other suitable construc through the passage I9 where it is brought to the desired temperature and from which it is dis charged 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 un derstood and although preferred embodiments of the invention are as illustrated and described, it is to be understood that furthermodiñcations 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 and changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed. 15 casing 21 of suitable metal having mounted 1on-l 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 gitudinally therein a horizontal partition 28 pro viding 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 hori zontally in opposite directions from the discharge 25 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 en 80 ters 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 pipe and having their outer ends extending up wardly, dampers in the branch pipes for control ling the flow of heated air therethrough, hoods. covering the upper ends of said upwardly extend ing 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 lead ing into the outlet pipe. ‘HENRY C.
