Improvements in or connected with Apparatus for Drying Grain,
Clothes, Fabrics, and other Articles or Produce.
I, VICTOR OBERMÜLLNER, of 36, Neubaugasse, Vienna, VII, in the Empire
of Austria, Chemist, at present residing at Lägendorf, Holstein, Germany, 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 :-
This invention relates to apparatus for drying clothes, grain, and other articles-
or produce, in which the articles to be dried are contained in or carried by conveyors
or travelling clothes horses or receptacles which are caused to pass through heated'.
conduits, flues, or other spaces.
It has been found in using apparatus of the description above specified that
the lubricant used upon the wheels or other running gear of the travelling
clothes horse or receptacles is liable to be quickly melted and evaporated by the
heat present in the drying conduit or flue. The smooth working of the apparatus
is thus interfered with and in some cases the forward motion of the clothes horse or
the receptacle may even be rendered altogether impossible, whereby the articles
conveyed by such receptacle or clothes horse are exposed to the danger of
becoming overheated or burnt. It has been proposed in order to overcome this
objection to provide the travelling receptacle or clothes horse with antifriction or.
ball bearings, but these means do not effect the object sought to be accomplished,
as their several parts are liable to become distorted by heat and rendered useless.
According to my invention the above mentioned defects in drying apparatus
are remedied by disposing the running gear of the travelling receptacles outside
of and at some distance away from the heated conduits, whereby the lubricant
used upon such parts is not detrimentally affected by the heat of the drying
conduit.
In the annexed drawings, Figure 1 shews a drying conduit provided with
improvements according to my invention; and Figure 2 represents a cross sectional
view of same.

With reference to the drawings, K designates the heated conduit or drying.
space, whose vaulted roof is supported by the girders and ties .. Disposed
within the side walls of the conduit are air ducts or passages r,
similar passages
being also provided in the roof of the conduit. The air which is subsequently used
to renew the air of the heated conduit K is first caused to pass through these
auxiliary ducts, whereby it becomes heated, and at the same time the walls and
roof of the conduit K are cooled and undue radiation of heat is prevented.
Baffling pieces n are provided in the ducts whereby the air passing through
them is more effectually heated.
Centrally disposed over the heated conduit K is the overhead railway i,
supported by brackets p from the girders s. Upon this railway the wheels k of
the carriage y are adapted to travel, and depending from the journal w of the
carriage is the frame m of the clothes horse or receptacle d, upon or in which
the goods to be dried are conveyed through the drying conduit K. The clothes
horse or receptacle d is pivotally connected with the lower ends of the frame, m,
so that the dried contents may be tipped therefrom when withdrawn from the
conduit.
To allow for the passage of the frame in, a slot or opening is provided in
the roof of the drying conduit; and so as to prevent the escape of the heating
gases through the opening, the frame m of each travelling receptacle is provided
with an inverted channel piece h, bolted to the frames m at a a, such channel piece h

page_text: being adapted to span the opening u and to dip into channels b, filled with liquid
or with sand, on each side of such opening. The channel pieces should be
extended at each end g, g', so as to form a joint with the pieces of the preceding
and succeeding receptacles d.
Baffle plates e and f are preferably attached to the receptacles d, so as to
cause the heated gases to more thoroughly permeate the contents of such
receptacles.

Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
1. In drying apparatus of the type above described, wherein clothes horses or
receptacles carrying the articles to be dried are caused to traverse a drying
conduit or space, the disposition of the running gear of such clothes horses or
receptacles outside of such drying conduit or space, in the manner and for the
purposes herein described and set forth with reference to the drawings hereto
annexed.
2. In drying apparatus of the type above described the disposition of air ducts
or spaces in the manner herein set forth and illustrated in the drawings hereto
annexed, whereby the heat radiating from such apparatus is absorbed by the air
passing through such ducts or spaces, for the purposes described.
3. In drying apparatus of the type above described, the arrangement and
combination of a slot or opening such as u and a cover such as h spanning such
opening and dipping into sand or liquid disposed on each side thereof, in the
manner and for the purposes herein described and set forth with reference to the
drawings hereto annexed.
Dated this 15th day of December 1892.
