IMPROVEMENTS IN MACHINERY OR APPARATUS FOR THRASHING GRAIN OR SEED
Year: 1865

page_text: PROVISIONAL SPECIFICATION left by Moritz Meisel at the Office of
the Commissioners of Patents, with his Petition, on the 16th March
1865. A communication from abroad by Isidore Pintus, of Berlin, in
the Kingdom of Prussia.
I, MORITZ MEISEL, Civil Engineer, of 1, Gloucester Terrace, Old Brompton,.
in the County of Middlesex, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR THRASHING GRAIN OR
SEED," to be as follows:-
This Invention has for its object improvements in machinery or apparatus
for thrashing out grain or seed from the ear or pod, whereby the breaking up
of the straw or stalk is to a great extent avoided, and the operation of
thrashing out the grain or seed is more advantageously performed, the.
machinery or apparatus arranged and constructed according to this Invention
being very simple and inexpensive as compared with the machinery and
apparatus usually employed for this purpose. The arrangement of machinery
or apparatus which it is preferred to employ according to this Invention
consists of a flat wheel or disc mounted upon a vertical or horizontal axis
(by preference the latter); this wheel or disc is composed of a rim or ring
connected to the hub by flat iron or any other suitable bars, acting as beaters
or rubbing instruments, or being caused to revolve at a short distance from a
fixed or stationary rubbing surface, composed by preference of a series of
similar bars to those forming the surface of the revolving wheel or disc, or
made in any other way to correspond therewith. The stationary rubbing

page_text: surface is not parallel to that of the revolving disc, but forms a certain angle
with the latter, so that the distance between the two gradually decreases from
where the stalks are to be admitted to the machine towards the opposite
opening by which they leave it. Although that angle is to be constant, the
space between the revolving bars or beaters and the stationary rubbing surface
may be regulated by a screw, or other suitable mechanism to cause the axis
of the wheel or disc to slide to and fro in its bearings; or the stationary
rubbing surface may be capable of adjustment to move it nearer to or farther
from the revolving wheel or disc, to which motion is communicated by suitable
mechanism so as to impart a high velocity to the periphery of the wheel.
The operating parts of the machine are enclosed, and spaces are left open
to receive the material and conduct it away. In order to prevent the stalks
coming in contact with the shaft upon which the revolving wheel or disc is
mounted, the opening by which they are to be fed into the machine is stopped
or covered up before it reaches the shaft. In place of forming the surface
of the revolving wheel or disc before described with single bars or beaters
having the spaces between them left open, the latter may be closed in at the
back, thus forming the surface into channels or grooves, the stationary
rubbing surface being formed to correspond therewith.
I would state that I have before obtained Provisional Protection for the
Invention of a similar machine, (numbered 1718, dated 9th July 1864,) but
I wish it to be understood that I claim in this application important improve-
ments on the former, namely, form and position of the disc and beaters, as
well as the new form and application of the mantel within which the stalks
are moving, and the way in which the revolving shaft is protected, so as to
prevent getting entangled with straw or other matter.
