Improvements in Thrashing-machines.
I, ANNA VON LOEPER, of 51, Paulstrasse, Rostock, Grand-Duchy of Mecklen-
burg, German Empire, Gentlewoman, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to a thrashing-machine by which not only all kinds of
grain but also all sorts of herbage for fodder may be thrashed in such a manner
that the remainder of the material thrushed-for instance straw-is in an
excellent condition and the grain is not hurt in the least. Just so the herbage
for fodder keeps its value as such, which could not be attained with the thrash-
ing-machines heretofore used. The improvements giving these results consist
of certain combinatious and arrangements of parts as are fully described herein-
after, and in order to make my invention more clear, I refer to the accompany-
ing drawings, in which similar letters denote similar parts throughout the several
views, and in which:-
-
Figure 1, is a front view of the machine, seen in the direction to the thrashing
device proper.
Figure 2, is a plan of the machine.
Figure 3, is a side view.
Figure 4, is a side view of the device for raising and lowering the thrashing
table.
Figures 5, 6, and 7, show some forms of construction of the transporting strap
for the material to be thrashed.
The construction is as follows:-
A base structure a, of suitable construction supports two pairs of bearings b,
that may be adjusted in a vertical direction. Each pair of these bearings support
in their turn a transporting roller c. The latter are preferably provided with
ribs or grooves upon and around their mantle surface, as shown in Figure 1,
ibe object of this arrangement being to secure the movement of the transporting
land which preferably consists of corrugated sheet metal, the corrugations of
which correspond to the ribs and grooves of the rollers.
Some forms of construction of transporting bands are shown in Figures 5-7.
The band 7, Figure 5, consists of sail cloth linen or the like, the upper surface
of this band being furnished with wooden bars e, of round or quadrangular
section whereas the lower surface is provided with similar bars, the section of
which corresponds to that of the grooves upon the rollers. In Figure 6, the
roller e, is replaced by two smooth pulleys d, over which run two straps d₁, of
corresponding breadth, which are connected with each other by a bast-mat d, or
the like. Figure 7, shows a similar arrangement as Figure 6. there being only
the difference that the straps da, are replaced by chain limbs d., over which also
a hand of a suitable material is spanned.
Reverting now to Figure 1, there are, of course, means for rotating the
rollers, although such means have not been shown. The band is conse-
quently moved in the same direction. The band serves for the reception of the

page_text: material to be thrashed; if this is grain the latter is so placed upon the band
that its halms lie cross wise to the direction of movement of the band, and
the ears are next to the thrashing device proper and slide over and upon a
thrashing table f, (Figure 3) when the rollers rotate.
The thrashing table is a straight plate with a roughened surface and is firmly
connected with the bearings b, as shown in Figure 1. In order to be able to
raise or lower the thrashing table, as is made necessary by the different kinds
of crops to be thrashed the machine is provided with a windlass h, consisting
materially of rotary gearing h₁, engaging with a rack i, which in its turn gears
with a lower cog-wheel i, so as to turn a shaft k, which rotates two other shafts k₁,
by the mediation of suitably located cog-wheels 1, 1. The axles k₁, carry cog-
wheels m, (Figure 4), which gear into racks m₁, (Figure 2) of the bearings b.
It is easily to be seen that according to the direction of movement of the
wheels h, the bearings b, will be raised and lowered, just the same taking place
also with the thrashing table because this is fixed to the bearings.
The thrashing device is constructed as follows:--The brackets, support a
shaft o, upon which may turn the lovers p, that are, at their longer front ends,
turned into a kind of hammers by being provided with layers of hard wood pr
The rear shorter end P, of the levers is actuated by projections, secured to a
shaft r.
Below the levers is a rubber cushions, (Figure 3), the object of which
is to render the blow produced by the falling hammers, elastic. Raising the
latter is produced by depressing the shorter ends of the levers by the projec-
tions 7, of the rotating shaft r. The latter are operated by pulleys &
The corn gained out of the grain is transported off the thrashing table by the
fresh grain fed into the machine, but auxiliary means may be arranged for this
purpose, for instance a strip of linen sliding along upon the thrushing table and
transporting the corn into the collecting sieve t, from whence they get into the
oscillating sieve for being freed from impurities. The holms of the thrashed
grain glide then down along upon rails, and during this time the corn that
remained in the grain falls also down into the receiver . The straw gels from
the rails u, upon the elevator for being at once transported away.
The hammers P₁, are located in two series, as shown in Figure 2, one hammer
of one series being located between two of the other series. There may, of
course, be more than two series. In either case the thrashing surface of each
hammer is equal to one half, one third, and so on, of the breadth of the thrashing
table, according to whether there are two, three or more, series of hammers.
It is a matter of course that to effectively thrash herbage for fodder only a
slight constructive change is requisite, viz.: arranging another shaft o, upon
which the hammers are arranged in such a manner that they are able to cover
the whole surface also of a broader thrashing table over which a band of sail
cloth, bast-mat or the like, glides. To prevent the corn from jumping away an
auxiliary wall consisting of a wooden frame and of a piece of linen covering
that frame may be used, the place of this wall being preferably the space over
and below the shaft o, so that the free movement of the hammers is not impeded.
The advantages derived from the afore-described machine consist in the straw,
the corn and the fodder herbage being in no way crushed or hurt, so that they
keep their full value. There is moreover no interruption of work by the straw
or the herbage winding, perhaps, around the drum, and finally the possibility of
an accident is, for the workmen, far less than with any other thrashing-machine.

I, ANNA VON LOEPER, of 51, Paulstrasse, Rostock, Grand-Duchy of Mecklen-
burg, German Empire, Gentlewoman, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:--
This invention relates to a thrashing-machine by which not only all kinds of
grain but also all sorts of herbage for fodder may be thrashed in such a manner
that the remainder of the material thrashed for instance straw-is in an
excellent condition and the grain is not hurt in the least. Just so the herbage
for fodder keeps its value as such, which could not be attained with the thrash-
ing-machines hereinbefore used. The improvements giving these results consist
of certain combinations and arrangements of parts as are fully described herein-
after, and in order to make my invention more clear, I refer to the drawings
left with my Provisional Specification in which similar letters denote similar
parts throughout the several views, and in which:-
Figure 1, is a front view of the machine, seen in the direction to the thrashing
device proper.
Figure 2, is a plan of the machine.
Figure 3, is a side view.
Figure 4, is a side view of the device for raising and lowering the thrashing
table.
Figures 5, 6, and 7, show some forms of construction of the transporting strap
for the material to be thrashed.
The construction is as follows:-
A base structure a, of suitable construction Eupports two pairs of bearings b,
that may be adjusted in a vertical direction. Each pair of these bearings support
in their turn a transporting roller c. The latter are preferably provided with
ribs or grooves upon and around their mantle surface, as shown in Figure 1,
the object of this arrangement being to secure the movement of the transporting
band which preferably consists of corrugated sheet metal, the corrugations of
which correspond to the ribs and grooves of the rollers.
Some forms of construction of transporting bands are shown in Figures 5—7.
The band Figure 5, consists of sail cloth linen or the like, the upper surface
of this band being furnished with wooden bars e, of round or quadrangular
section whereas the lower surface is provided with similar barsel, the section of
which corresponds to that of the grooves upon the roller. In Figure 6 the
roller c, is replaced by two smooth pulleys, over which run two straps ³, of
corresponding breadth, which are connected with each other by a bast-mat d', or
the like. Figure 7, shows a similar arrangement as Figure 6, there being only
the difference that the straps d, are replaced by chain limbs, over which also
a band d, of a suitable material is spanned
Reverting now to Figure 1, there are, of course, means for rotating the
rollers c, although such means have not been shown. The band is conse-
quently moved in the same direction. The band serves for the reception of the
material to be thrashed; if this is grain the latter is so pluced upon the band
that its halms lie cross wise to the direction of movement of the band, and
the ears are next to the thrashing device proper and slide over and upon a
thrashing table f, (Figure 3) when the rollers rotate.
The thrashing table is a straight plate with a roughened surface and is firmly
connected with the bearings b, as shown in Figure 1. In order to be able to

page_text: raise or lower the thrashing table, as is made necessary by the different kinds
of crops to be thrashed the machine is provided with a windlass h, consisting
materially of rotary gearing ', engaging with a rack i, which in its turn gears
with a lower cog-wheel it, so as to turn a shaft k, which rotates two other shafts k¹.
by the mediation of suitably located cog-wheels 1, 1. The axles k, carry cog-
wheels (Figure 4), which gear into racks m', (Figure 1) of the bearings b.
It is easily to be seen that according to the direction of movement of the
wheels 4, the bearings b, will be raised and lowered, just the same taking placo
also with the thrashing table because this is fixed to the bearings.
The thrashing device is constructed as follows:--The brackets, support a
shaft o, upon which may turn the lovers p, that are, at their longer front ends,
turned into a kind of hammers by being provided with layers of hard wood p³.
The rear shorter end, of the levers is actuated by projections q, secured to a
shaft r.
Below the levers is a rubber cushions, (Figure 3), the object of which
is to render the blow produced by the falling hammers, elastic.
Raising the
latter is produced by depressing the shorter ends of the levers by the projec-
tions q, of the rotating shaft r. The latter are operated by pulleys s¹.
The corn gained out of the grain is transported off the thrashing table by the
fresh grain fed into the machine, but auxiliary means may be arranged for this
purpose, for instance a strip of linen sliding along upon the thrashing table and
Transporting the corn into the collecting sieve f, from whence they get into the
oscillating sieve for being freed from impurities. The halms of the thrashed
grain glide then down along upon rails, and during this time the corn that
remained in the grain falls also down into the receiver. The straw gets from
the rails, upon the elevator for being at once transported away.
The hammers, are located in two series, as shown in Figure 2, one hammer
of one series being located between two of the other series There may, of
course, be more than two series. In either case the thrashing surface of each
hammer is equal to one half, one third, and so on, of the breadth of the thrashing
table, according to whether there are two, three or more, series of hammers.
It is a matter of course that to effectively thrash herbage for fodder only a
slight constructive change is requisite, riz.: arranging another shaft o, upon
which the hammers are arranged in such a manner that they are able to cover
the whole surface also of a broader thrashing table over which a bund of said
cloth, bast-mat or the like, glides. To prevent the corn from jumping away an
auxiliary wall consisting of a wooden frame and of a piece of linen covering
that frame may be used, the place of this wall being preferably the space over
and below the shaft o, so that the free movement of the bummers is not impeded.
The advantages derived from the afore-described machine consist in the straw,
the corn and the fodder herbage being in no way crushed or hurt, so that they
keep their full value. There is moreover no interruption of work by the straw
or the herbage winding, perhaps, around the drum, ond finally the possibility of
an accident is, for the workmen, far less than with any other thrashing-machine.
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:-
(1) In a thrashing-machine, the combination with a thrashing-table adapted
to be adjusted vertically, of hammers located so as to strike upon that lable, an
endless transporting-band, means for supporting the latter and for operating the
parts named, substantially as described.
(2) In a thrashing-machine, the combination with the thrashing-table adapted
to be adjusted vertically, of hammers located so as to strike upon that table, a

actuating the roller, substantially as described.
(3) In a thrashing-machine, the combination with a thrashing-table adapte.l

page_text: to be adjusted vertically, of hummers located so as to strike upon that table,

to be adjusted vertically, of hammers located so as to strike upon that table,
endless transporting band consisting of corrugated sheet-metal, rollers supporting
this band and having ribs and grooves corresponding to the corrugations of the
said hand, and means for moving the rollers, substantially as described.
(65) In a thrashing-machine the combination with a thrashing-table adapted
to be adjusted vertically, of hammers located so as to strike upon the table,
endless transporting band consisting of sail cloth or its equivalent, and bars
