PROVISIONAL SPECIFICATION.
Apparatus for Drying Sheets of Paper.
I, ADAM HOEHL of Dresden in the German Empire, Engineer do hereby declare
the nature of this invention to be as follows:-
This invention has reference to an apparatus for quickly and economically drying
sheets of paper. It consists of a number of frames on which the sheets of paper to
be dried are laid, which frames are fixed by studs on an endless chain driven by wheels
fixed horizontally one above another on a vertical shaft at the front end of the
apparatus. The line of travel of the endless chain is first obliquely upwards and
forwards, then nearly horizontal to the back end of the apparatus and round a chain
wheel or pulley loose on a second vertical shaft, thence somewhat inclined downwards
back again in a forward direction round a fixed chain wheel on the vertical driving
shaft at the front end of the apparatus, then again to the back end and round a second
loose chain wheel on the back vertical shaft and so on round a number of chain
wheels placed one above another on the two vertical shafts so that the chain moves
in a spiral like path downwards until the lowermost point of travel is reached when
the movement is again oblique upwards and forwards as before. The movement may
take place in the opposite direction.

COMPLETE SPECIFICATION.
Apparatus for Drying Sheets of Paper.
I, ADAM HOEHL of Dresden in the German Empire, Engineer, 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 has reference to an apparatus for quickly and economically drying
sheets of paper and like materials.
In the accompanying drawing Fig. 1 is a side elevation and Fig. 2 a plan of the
same.
The apparatus works with only one endless chain provided with studs or pins a.
The frames b on which are laid the sheets to be dried have holes or recesses in their
central part for taking on to the studs a on which they are placed to be carried along
by the endless chain. The frames are guided by and carried along rails c the motion
being communicated from pullies d. At A the endless chain travels obliquely upwards
passing over rollers e to the top back chain wheel round which it passes then
forward again to the front chain wheel round which it passes, then backwards to
the second back chain wheel f³, thence to f, f³, f until it reaches A whence it
again travels obliquely upwards and forwards as before. The movement may take
place in the opposite direction.
The sheets to be dried are laid on the frames at A travel along the aforesaid path
and arrive dry at a where they are taken off.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is:
An apparatus for drying sheets of paper in which the frames are carried through
the drying space on an endless chain which travels through the drying space over
horizontal chain wheels f in an upward or downward winding path, substantially
as described and shewn.
