Improvement in or relating to Threshing Machines.
I, FERDINAND KORB of Freienwalde on the Oder, in the Empire of Germany,.
Mechanical 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 :-
The present invention relates to threshing machines and consists in the arrange-
ment of an elevator which is supplied with the material falling down from the
shaking sieves or screens through a channel which is shaken together with the
aforesaid shaking sieves or screens.
This elevator now serves to convey the said material to a second channel
which opens into the winnowing machine and which is also constantly shaken to
and fro.
с
As shown in the accompanying drawings (in which Fig. 1 is a side view and
Fig. 2 an end view of a threshing machine having my present improvements
applied thereto) the elevator is constituted by a wheel a which is provided with a
number of vanes a' between its outer and its inner rims. This wheel is rotated.
or driven from the shaft d by means of a chain c which passes around the outer
rim or periphery of the said wheel a (which may be toothed or otherwise suitably
formed for this purpose) and also passes around a suitable driving wheel
During the rotation of the wheel a its vanes a' take up each a suitable quantity
of the material which is supplied through the channel or trough e and when
said vanes have risen to a suitable height they discharge said material on to the
channel or trough f. This latter is freely suspended in an almost horizontal
position by means of a suspension link g at one end and by means of the supports g
at the other end.
The channel f is shaken or vibrated by means of the lever mechanism h h¹ by
the action of an eccentric or cam mounted, on the main shaft of the inachine the
result of such shaking being to feed the material resting on the channel f gradually
towards the winnowing machine. The channel e is freely suspended with a certain
amount of inclination at one end and is jointed or pivoted at its other end to the
lowest shaking sieve i and is therefore compelled to partake of the to-and-fro
motion of the latter so that the material which falls down from the sieves and is
guided by the guides k k on to the chanuel e is gradually conveyed to the
elevator.
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:-
1. In threshing machines an elevator such as a a to which the material that
falls down from the shaking screens or sieves is supplied by a channel or trough e
which latter is caused to share the shaking motion of the said screens or sieves in
combination and acting in conjunction with a second channel or trough such as f
said elevator serving to feed or convey this material on to said second channel or
trough which is likewise rapidly shaken or vibrated and terminates or discharges
at the point where it is to be winnowed substantially in the manner and for the
purposes herein before described.
2. In threshing machines of the character claimed above-the combination
therewith of an elevator consisting of a wheel a which is provided with a number

page_text: of vanes a between its outer and its inner rim and which is driven by means of an
endless chain or equivalent such as c passing around the periphery or outer rim of
said wheel a substantially as and for the purposes hereinbefore described.
3. The improved arrangement and construction of threshing machines substan-
tially in the manner and for the purposes hereinbefore described and illustrated in
the drawings hereunto annexed.
