thus be seen that an apparatus has been provided
whereby a constant ñow oi' fresh. warm air

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

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.
