PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Drying Fabrics or other Materials.
I, CARL ZACH, of Coesfeld, Westphalia, in the Empire of Germany, Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to a drying apparatus which is simple in construction and
of great capacity and is especially adapted for use in connection with dressing
machines but can also with advantage be used for other purposes.
In carrying out my invention I provide a closed chamber or casing made
preferably of wood. At the bottom inside the chamber are placed steam heating
tubes and at each end of the upper part are a number of rollers over which travels
a web or band. At the end of the box opposite to the entrance of the chain and
at the bottom of the chamber is an inlet pipe for fresh air.
Above the heating
tubes is a pipe for exhausting damp air from the apparatus. The lower half of
this pipe extends right across the box and midway of its length. Consequently the
fresh air is compelled to pass over the whole surface of the heating tubes before it
can reach the upper part of the chamber to act upon the fabrics or other materials
to be dried on the travelling web or band. The moisture with which the air is
saturated is deposited on the lower half of the widened pipe and escapes through
the exhaust.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Drying Fabrics or other Materials.
I, CARL ZACH, of Coesfeld, Westphalia, in the Empire of Germany, Manu-
facturer, do hereby declare the nature of this invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My invention relates to a drying apparatus which is simple in construction and
of great capacity and is especially adapted for use in connection with dressing
machines but can also, with advantage, be used for other purposes.
In the accompanying drawing,
Figure 1 is a longitudinal section; and,
Figure 2 is a transverse section of an apparatus for drying fabrics or other
materials, constructed according to my invention.
In carrying out my invention I provide a closed chamber or casing A made
preferably of wood. At the bottom, inside the chamber, are placed steam-heating
tubes B and at each end of the upper part are a number of rollers Dover which a
web or band E travels in the direction indicated by the arrows in Figure 1. At
the end of the chamber opposite to the entrance of the web or band and at the
bottom of the chamber is an inlet pipe C for fresh air. Above the heating-tubes
is a pipe F for exhausting damp air from the apparatus. The lower half of this,
pipe F extends right across the chamber, as shewn in Figure 2, and midway of its
length, as shewn in Figure 1. Consequently the fresh air coming from the pipe C
is compelled to pass over the whole surface of the heating-tubes before it can reach
the upper part of the chamber to act upon the fabrics or other materials to be
dried on the travelling web or band. The moisture with which the air is saturated

exhaust.
The air thus ascends at one end of the chamber A and when saturated descends
at the other end of the chamber onto the exhaust pip..
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A drying apparatus in which the lower half of a portion of the exhaust pipe
situated above the heating pipes extends the whole width of the apparatus and
midway of its length, so that the fresh air introduced underneath the said portion
of the exhaust pipe shall ascend at one end of the apparatus and when saturated
with moisture descend at the other end onto the said portion of the exhaust pipe
by which it is discharged from the apparatus, substantially as hereinbefore
described.
2. The improved apparatus for drying fabrics or other materials herein before
described and illustrated in the accompanying drawing.
