An Improved Thrashing Machine.
I, HERMANN WAGENER of Baku, Kaukasus, Russia, Gentleman 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 thrashing machines and the manner in which I prefer to
carry my invention into effect is shewn in the accompanying drawings of which
Fig. 1 is a longitudinal and
Fig. 2 a cross section.
Fig. 3 is a detail.
The general outside appearance of a thrashing machine, according to my invention
is in almost every particular like the ordinary thrashing machines, the internal
mechanisms and also the manner in which I construct the frame-work being, how-
ever, in many points peculiar and novel thus constituting the subject matter of the
invention.
The frame-work consists in the main of the four beames T, T¹, T2 and T³, which
are disposed in such a manner that they form a figure reminding of a large roman W,
as will be distinctly seen in the drawings. This construction gives great rigidity with
comparative lightness.
The mechanical parts proper consist of the thrashing contrivance A and B, the
endless sieve E, worked by rollers C and D, the sieve-knockers F and F¹, affixed on
shafts G and G, respectively, the grain shoots 1, the grain sieves K, fan V, the
eccentrics on shaft L for shaking sieves K and the dust collecting board M.
The thrashing contrivances A and B consist of the thrashing roller A, provided
with several rows of pins, quite in the usual manner, and the thrashing bed B which
is in so far different from the usual thing as it is provided with pins only in part of
its length. The corn to be thrashed enters at a from the hopper Z, but from the
point a to the point the bed is quite smooth and there are pins only from the point
to c, such pins being of course disposed in the usual manner, relatively to the pins of
the roller A. My object in providing no pins in the first part of bed B is to cause
the corn to arrive at the point, where the pins commence, in a more evenly distributed
layer, the pins X acting as feeders. It need not be said that the roller A revolves
with very great speed in the usual manner of thrashing machines and from it all
necessary transmissions issue.
Fig. 3 is a ground plan of the thrashing bed B with pins y in part of its length.
The thrashed straw and grain on issuing from the thrasher A B, falls on the endless
sieve E, which travels in direction from left to right provided the thrasher, as in
drawing is to the left.
The said endless sieve consists of the sieve proper, which is generally thin perforated
metal, mounted either on leather straps or on ropes a as in drawing (Fig. 2) and pro-
vided at suitable intervals with cross-pieces r, which have the double object of keeping
the sieve straightened and of preventing the long straw from resting dead on the
sieve itself which would make the separation of grain and straw more difficult.
Affixed to shaft G and G₁ respectively are the roller-knockers F and F¹, the object
of which are to shake the sieve E by beating against its bottom in the manner
readily to be seen in the drawings.
While the straw passes over the sieve and out by H, falling into a van or other
receptacle, the corn drops through the meshes and on to the shoots I, whence it slides
through opening I¹ on to the cleansing sieves K, which are set into a shogging
motion by means of excenters on shaft L, quite in the usual manner of grain
purifying sieves, the winnowing fan V blowing dust and light particles on to the
dust collecting board M, whence it is removed in any convenient manner.

to the sieve E.
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 is
In thrashing machines:
1. The arrangement of a thrashing bed B, the latter half of which only is pro-.
vided with thrashing pins, the first half being smooth, substantially in the manner
as and for the purpose described and as shewn in the drawings.
2. A straw-shaker consisting essentially of an endless sieve, running on roller C
and D, and agitated by means of roller-knockers all substantially in the manner
as and for the purpose described and as shewn in the drawings.
