Improvements in Dressing and Cleaning Machines for Grain and
similar Materials.
I, FRANZ HOLTZHAUSEN, of Nossen, Kingdom of Saxony, in the Empire of
Germany, 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 consists of a rotating drum or rotating beaters arranged inside
a sieve or cover of a cylinder, which is mounted in such a manner that it can be
adjusted relative to the said drum or beaters.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a longitudinal section and Fig. 2 a cross section of a dressing
machine.
a
is
are
a shaft which is mounted in the bearings b, b. On the shaft a
discs c, c on which are positioned rails d which are furnished with brushes c¹.
In lieu of individual rails a closed drum may be used and in lieu of brushes,
in cleaning and scalping machines in particular, any other material may be used
such as emery, sand stone or the like.
Around the drum brush is arranged a sieve or cover d¹ which runs below on
two pulleys e, e, and on the side on pulleys f, f. The latter are arranged in such
a manner, that they can be adjusted horizontally so as to enable the adjustment
of the sieve or cover also in the same direction.
Through the adjustment of the sieve or cover, it is possible to alter the
distance of the drum from the sieve or cover d¹ in accordance with the material
to be treated, which may require more or less grip and as the brushes get worn.
In the drawing the adjustment of the pulleys f, f, is effected by loosely inserting
the wall g, so that the same may be tilted on its lower edge.
The adjustment of the wall' takes place by handles h guided on bolts i and
retained in position by nuts k, kl.
It will be evident that the said wall may also be fastened at its lower edge by
means of hinges and retained in position at the top in any other suitable manner
and that the pulleys f, f, may be employed adjustable on a fixed wall.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is-
1st. A dressing and cleaning machine with a drum or beaters which are
furnished with brushes, stone, emery or other material serving for dressing or
cleaning; the adjustment of the cover or cylinder rotating around the said drum
or beaters through the displacement of side supporting pulleys in a perpendicular
or nearly perpendicular direction, all substantially as set forth.
2nd. In the arrangement specified in the preceeding claim, the adjustment of
supporting pulleys ff, by tilting the wall carrying the said pulleys on its lower
edge, all substantially as set forth.
