I, JAN HAUER, of Molitorov, near Könnern, Bohemia, in the Empire of Germany,
Engineer, do hereby declare the nature of my said invention to be as follows:-
The object of my invention is to increase the efficiency of machines for threshing
grain.
In carrying out my invention, I fit two rotary beaters at the end of the oscillating
straw carriers. These rotary beaters are mounted side by side, their axles being
parallel with each other. Each beater is formed of two parallel iron bars, suitably united
to the axles. Driving pullies are fitted to the axles whereby the beaters are driven;
the outside beater being driven at double the speed of that nearest to the oscillating
straw beaters. Both beaters run in the same direction, and receive the straw from
above, the heaters striking the straw upwards and carrying it away.
In this manner the layer of straw is drawn out and separated, and each sheave
is beaten thoroughly from below, so as to thresh it out thoroughly; the grains
falling down and being gathered, while the empty straw is thrown out by the outer
beater.

Improvements in Threshing Machines.
I, JAN HAUER, of Molitorov, near Könnern, Bohemia, in the Empire of Austria,
Engineer, do hereby declare the nature of my said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
The object of my invention is to increase the efficiency of machines for threshing
grain.
In carrying out my invention, I fix two or more rotary beaters at the end of the
oscillating straw carriers. These rotary beaters are mounted side by side, their
axles being parallel with each other. Each beater is formed of two parallel iron bars,
suitably united to the axles. Driving pullies are fitted to the axles whereby the
beaters are driven; the outside beater being driven at double the speed or there-
abouts of that nearest to the oscillating straw beaters. The beaters run in the same
direction, and receive the straw from above, the beaters striking the straw upwards
and carrying it away.
In this manner the layer of straw is drawn out and separated, and each sheave is
beaten thoroughly from below, so as to thresh it out thoroughly; the grains falling
down and being gathered while the empty straw is thrown out by the outer heater.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation, and Fig. 2 a plan, shewing the application of
to a threshing machine.
my
invention
a is the threshing machine, from the carriers of which the straw is carried to the
beaters bc. The beaters consist of iron bars b¹ c¹ fixed to axles de by radial bars fg.
The beaters are caused to revolve in the direction of the arrows.
The beaters are mounted close together, in such a manner as to form a continuation
of the oscillating straw carriers.
The axles de are mounted on light iron brackets & fitted to the upright frame k-
This frame carries the driving gear for actuating the beaters. The pulleys mn
fitted to the driving axlo o drive the pulleys pr by means of belts or driving bands.
The pulley runs at about double the speed of p both being driven in the direction
shown by the arrows.
The speed is usually arranged so that the beater p runs at 100 revolutions in a
minute, and at 200. But other velocities may be used.
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. In combination with threshing machines the method of effecting the thorough
threshing of the straw by means of two or more rotary beaters be placed close

page_text: together, and driven so as to throw the straw upwards, substantially as hereinbefore
described and shewn on the drawings.
2. In combination with threshing machines as aforesaid, the horizontal rotary
beaters or frames be forming a continuation of the oscillating straw-carriers, of
threshing machines, the first rotary beater receiving the straw from the carriers, and
throwing it to the second, the latter revolving at a higher speed than the first and so
on for more than two such beaters, substantially as hereinbefore before described and
shewn on the drawings.
3. In combination with existing threshing machines as aforesaid, the addition
thereto of rotary beaters as a continuation of the oscillating straw carriers, or the
combination of the same in the construction of new threshing machines, as an integral
part of the saine, with obvious modifications, substantially as and for the purposes
hereinbefore described and shewn on the drawings.
4. The general construction, combination, and arrangement of the several and
respective parts, together forming my improvements in threshing machines, sub-
stantially as herein before described and shewn on the drawings.
