Improvement in Machines for Threshing Clover.
I, AMANDUS HAGEN Workmaster of Troisdorf in the Province of Rhineland and
Kingdom of Prussia do hereby declare the nature of this invention to be as
follows:-
The present invention relates to an improvement on the clover threshing
machines hitherto known in which a friction cone rotates in a conical case and
in which the clover is threshed out between the casings of these two parts of the
machine, which have their friction surfaces covered with an elastic material
(gutta percha).
The improvement consists in the conical case, furnished with a receiving funnel
being adjustable as regards height and in the friction cone rotating by means
of a toothed-ring, in which the driving wheel catches, turning loosely on a rigid
shaft.
Owing to the fact of the shaft not turning and all the rotating shafts and bear-
ings being placed under the friction cone a great drawback is removed viz. that
of the bearings at the bottom of the case becoming dirtied by the chaff and clover
seeds.
Fig. 1 of the accompanying drawing shews a view of the machine and Fig. 2
a section of it.
The apparatus consists with regards to its chief parts as in the other clover
threshing machines of two conical bells a and 1, which lie one upon the other
in such a manner that a space remains between the surfaces of the cases facing
each other.
These surfaces have, as is usual, a covering ss of strong elastic material to
enable them to seize the material, which arrives between them and cause it to
be rubbed together. The upper bell a stands firmly in the frame; the lower
bell a 1, on the contrary, turns loosely on a vertical shaft and possesses near to
the lower end in the inside a toothed ring f on which the wheel impelled by the
crank catches so that the bell al can be made to rotate.
The upper bell a, which for the purpose of feeding the material, is provided
with the receiving funnel b as already mentioned and can be always adjusted as
regards height according to the quantity of the material to be threshed.
To this end a cross-piece with an eye is arranged in the receiving funnel, by
means of which the bell is set on a square continuation of the shaft e.
The upper end of this continuation is furnished with a screw thread on which
a thumb-screw k is set. This catches under a cross-piece funnel b and raises
or lowers more or less the outside casing from its normal position, according as it
is turned round to the right or left on the screw-thread.
A still further advantage lies in the fact of the driving power being within the
bell a 1.
On the one hand the seeds are prevented thereby from being crushed by the
wheels and on the other hand as cannot fail to be the case with the machines

page_text: possibility of
hitherto known, which have a moveable vertical shaft, there is no
the bearings being dirtied by chaff and seeds falling into the lubricant.
Of course the machine can be worked by hand as well as by motor power.
When the funnel 6 is filled with clover the bell a 1 is made to rotate, as already
described; this causes the seed to come between the rotating friction surfaces and
it is gently rubbed by the very elastic covering of gutta percha, whereby the outer
husk but not the seeds themselves are crushed.
Chaff and seeds fall into a box placed slantwise and from here into vessels
sieves or other similar contrivances for separating the seeds from the husks.

I, AMANDUS HAGEN, Merchant of Troisdorf in the Province of Rhineland and
Kingdom of Prussia, 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 an improvement hitherto known on the clover
threshing machines in which a friction cone rotates in a conical case and
in which the clover is threshed out between the casings of these two parts of the
machine, which have their friction surfaces covered with an elastic material
(gutta percha).
The improvement consists in the conical case, furnished with a receiving funnel
being adjustable as regards height and in the friction cone rotating by means
of a toothed-ring, in which the driving wheel catches, turning loosely on a rigid
shaft.
Owing to the fact of the shaft not turning and all the rotating shafts and bear-
ings being placed under the friction cone a great drawback is removed viz., that
of the bearings at the bottom of the case becoming dirtied by the chaff and clover
seeds.
Fig. 1 of the drawing filed with the Provisional Specification shows a view of
the machine and Fig. 2 a section of it.
The apparatus consists with regards to its chief parts as in the other clover
threshing machines of two conical bells a and a 1, which lie one upon the other
in such a manner that a space remains between the surfaces of the cases facing
each other.
These surfaces have, as is usual, a covering ss1 of strong elastic material to
enable them to seize the material, which arrives between them and cause it to
be rubbed together. The upper bell a stands firmly in the frame; the lower
bell a 1, on the contrary, turns loosely on a vertical shaft c and possesses near to
the lower end in the inside a toothed ring f on which the wheel i impelled by the
crank catches so that the bell a 1 can be made to rotate.
The upper bell a, which for the purpose of feeding the material, is provided
with the receiving funnel b as already mentioned and can be always adjusted as
regards height according to the quantity of the material to be threshed.
To this end a cross-piece with an eye is arranged in the receiving funnel, by
means of which the bell is set on a square continuation of the shaft e.
The upper end of this continuation is furnished with a screw thread on which

page_text: a thumb-screw k is set. This catches under a cross-piece of the funnel b and raises
or lowers more or less the outside casing from its normal position, according as it
is turned round to the right or left on the screw-thread.
A still further advantage lies in the fact of the driving power being within the
bell a 1.
On the one hand the seeds are prevented thereby from being crushed by the
wheels and on the other hand as cannot fail to be the case with the machines
hitherto known, which have a moveable vertical shaft, there is no possibility of
the bearings being dirtied by chaff and seeds falling into the lubricant.
Of course the machine can be worked by hand as well by motor power.
When the funnel b is filled with clover the bell a 1 is made to rotate, as already
described; this causes the seed to come between the rotating friction surfaces and
it is gently rubbed by the very elastic covering of gutta percha, whereby the outer
husk but not the seeds themselves are crushed.
Chaff and seeds fall into a box placed slantwise and from here into vessels
sieves or other similar contrivances for separating the seeds from the husks.
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:-
An improvement in the clover rubbing machines hitherto used, which have two
friction cones placed one on the other, one of which rotates, distinguished by
(1) The arrangement of the conical case a on the square continuation of the
vertical shaft c by means of a cross-piece provided with an eye as well as of a
thumb-screw catching under cross-pieces of the receiving funnel, on a screw-
thread of the continuation of the shaft in such a manner that by the screwing
or unscrewing of the thumb-screw the case is adjustable as regards height.
(2) The arrangement of the friction cone al which turns loosely on the rigid
vertical shaft c and possesses at the lower end a circular rack f, in which the
driving wheel i, lying in a similar manner inside the bell, catches, for the purpose
of preventing the bearings coming into contact with the clover and also to prevent
the clogging of the former by the latter.
