I GEORGE DOWNING, Patent Agent of 8 Quality Court, Chancery Lane, London
in the County of Middlesex do hereby declare the nature of my Invention for
AN IMPROVED ARRANGEMENT OF THE DRIVING STRAP FOR THRASHING MACHINES,
a communication to me by Carl August Klinger of Altstadt, Stolpen in the German
Empire Machine Manufacturer to be as follows:-
My invention relates to an improved arrangement of the driving strap for
thrashing machines.
The six shafts of the thrashing machine are so arranged that a single strap
serves to transmit power and motion to the same.
A strap drum is affixed to the main driving shaft of the thrashing cylinder over
which said drum the driving strap is passed which said strap runs from thence
round the drum fixed to the crank shaft for the sifting device round the drum
fixed to the crank shaft for the sifting device, round the drum on the shaft to the
straw shaker, round the drum on the ventilator shaft and also around the drum
on the elevator shaft and from thence around a drum affixed to a suitable shaft
which said shaft can be adjusted according to the desired tension of the driving
strap.

I GEORGE DOWNING, Patent Agent of 8 Quality Court, Chancery Lane, London
in the County of Middlesex do hereby declare the nature of my Invention for
AN IMPROVED ARRANGEMENT OF THE DRIVING STRAP FOR THRASHING MACHINES,
a. communication to me by C. A. Klinger of Altstadt, Stolpen in the German
Empire 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 an improved arrangement of the driving strap for
thrashing machines.
The six shafts of the thrashing machine are so arranged that a single strap
serves to transmit power and motion to the same.
The accompanying Figure represents a side view of a thrashing machine with
my improvement applied to the same.
a is the strap or driving drum, b is the drum fixed to the shaft of the sifting
device; c is the drum fastened to the shaft of the straw shaker, d is the drum on
the ventilator shaft, e is the drum for driving the worm or other gearing for the
elevator.
f is an adjustable tension roller for giving the strap sufficient tension.
The strap drum a is affixed to the main driving shaft of the thrashing cylinder
over which said drum the driving strap is passed which said strap runs from thence
under or round the drum b fixed to the crank shaft for the sifting device, over or
round the drum c on the shaft to the straw shaker, under or round the drum d on
the ventilator shaft and also above or around the drum e on the elevator shaft and
from thence under or around a drum f affixed to a suitable shaft which said
shaft can be adjusted according to the desired tension of the driving strap.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim and desire to secure by Letters Patent is
A strap driving drum for thrashing machines consisting of a driving strap which
is put under tension by means of a suitable tension roller and passes successively
over below or around a series of drums for simultaneously driving the thrashing
drum, the sifter, straw shaker, ventilator and elevator substantially as described in
the foregoing specification and shown in the accompanying drawings.
