PROVISIONAL SPECIFICATION.
Improvements in and connected with Corn-ear-conveyers for
Harvesting-machines.
I, FRIEDRICH CARL MEHRTENS, 19, Heim Strasse, of Berlin, Kingdom of
Prussia, Germany, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to an improved corn-ear-conveyer or lifter for corn-
harvesters and harvesting-machines in general and has for its object to effect a
more efficient construction of same.
The conveyor forming the subject of this invention, consists in general of a
spiral or screw, which is journaled or has its bearing in a kind of wedge-shaped
frame or casing located in the front of a machine or harvester, motion being
imparted to the said screw-conveyor from the driving wheel of the machine, or,
the said conveyor may of course be actuated or driven in any other suitable
manner.
The wedge-shaped casing or frame of the conveyor is propelled into the bending
corn-stalks, whereby the rotating screw or spiral conveyor projecting from the
before mentioned wedge-shaped frame causes the said stalks to come to lie against
the slanting edge of the said frame of the conveyor, and to be fed in an upright
position towards the knives of the machine.
I have illustrated my invention in the accompanying drawing, in which
similar letters denote similar parts, and in which;-
Figure 1 shows the general arrangement of a harvester with my improved
screw-conveyor attached, whilst
Figure 2 is a separate view of the said screw-conveyor, the front-wall of the
casing or frame of the same being omitted to render the chief parts more distinct.
The harvester represented in Figure 1 is of known construction, in which con-
nection may be mentioned, that my improved screw-conveyor may be used on a
harvester or mowing-machine of any description, the machine represented in
Figure 1 being, as hereinbefore indicated, simply drawn as an example, for the
purpose of more clearly showing my invention.
Proceeding to describe the drawing, I remark: The table c of the machine
is supported from the two driving wheels a and b and from the front of said
table the knives are actuated in known manner from the large driving-
wheel by suitable gearing.
Furthermore a number of rakes e are arranged to be actuated in such manner,
that the corn-stalks cut by the knives d are transported by the said rakes, so
that the said stalks come to lie at the rear of said rakes.
The especial form and arrangement of the wedge-shaped conveyor-casing f as
also the interior parts of same will be clear from the perspective view in Fig. 1,
and the sectional view in Figure 2, as also the position of the parts of the con-
veyor with regard to the general arrangement of the harvester.
Describing the conveyor more especially, I remark, Figure 2 shows, as indicated,
the outer casing f in section.

page_text: On the upper partly open slanting side of the said casing f, is the screw or
spiral proper journaled at h and i, so as to permit of the revolution of the same
in such manner, that the upper spirals of the conveyor proper project constantly
beyond the top edge of the said casing f.
The rotating or revolving movement is imparted to the conveyor or screw
proper g, in the example shown in Figure 2 by the employment of an especial
driving-wheel k, though it will be clear that I may, within the limits of my
invention, vary the construction of the driving gear of the conveyor, as also the
special arrangement of the parts, without departing from the principle of my
said invention.
In the said example of Figure 2 the said driving wheel k is arranged to revolve
upon an axle 1, located as shown in the frame or casing f of the conveyor,
said axle being provided or combined with a cog-wheel m. The said-cog-wheel m
will, as is clear, transmit the motion of the driving-wheel & by aid of a second
cog-wheel mounted upon a second shaft o, at the other end of the said shaft o
is a cog-wheel p, engaging with a similar cog-wheel q located at the upper end
of the shaft of the conveyor proper g.
The construction & arrangement of the parts will be clear without further
description.

Improvements in and connected with Corn-ear-conveyers for
Harvesting-machines.
I, FRIEDRICH CARL MEHRTENS, 19, Heim Strasse, of Berlin, Kingdom of
Prussia, 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 relates to an improved corn-ear-conveyor or lifter for corn
harvesters and harvesting-machines in general and has for its object to effect a
more efficient construction of same.
The conveyer forming the subject of this invention, consists in general of a
spiral or screw, which is journaled or has its bearing in a kind of wedge-shaped
frame or casing located in the front of a machine or harvester, motion being
imparted to the said screw-conveyer from the driving wheel of the machine, or,
the said conveyer may of course be actuated or driven in any other suitable
nanner.
The wedge-shaped casing or frame of the conveyer is propelled into the bending
corn-stalks, whereby the rotating screw or spiral conveyer projecting from the
before mentioned wedge-shaped frame causes the said stalks to come to lie against
the slanting edge of the said frame of the conveyer, and to be fed in an upright
position towards the knives of the machine.
I have illustrated my invention in the drawing filed with the Provisional
Specification, in which similar letters denote similar parts, and in which:
Fig. 1 shows the general arrangement of a harvester with my improved
screw-conveyer attached, whilst
Fig. 2 is a separate view of the said screw-conveyer, the front-wall of the
casing or frame of the same being omitted to render the chief parts more distinct.

page_text: The harvester represented in Fig. 1 is of known construction, in which con-
nection may be mentioned, that my improved screw-conveyer may be used on a
harvester or mowing-machine of any description, the machine represented in
Fig. 1 being, as herein before indicated, simply drawn as an example, for the
purpose of more clearly showing my invention.
Proceeding to describe the drawing, I remark: The table c of the machine
is supported from the two driving wheels a and b and from the front of said
table the knives d are actuated in known manner from the large driving-
wheel b by suitable gearing.
Furthermore a number of rakes are arranged to be actuated in such manner,
that the corn-stalks cut by the knives are transported by the said rakes, so
that the said stalks come to lie at the rear of said rakes.
The especial form and arrangement of the wedge-shaped conveyer-casing. fas
also the interior parts of same will be clear from the perspective view in Fig. 1,
and the sectional view in Fig. 2, as also the position of the parts of the con-
vever with regard to the general arrangement of the harvester.
Describing the conveyer more especially, I remark: Fig. 2 shows, as indicated,
the outer casing f in section.
On the upper partly open slanting side of the said casing f, is the screw or
spiral proper journaled at h and i, so as to permit of the revolution of the same
in such manner, that the upper spirals of the conveyer proper project constantly
beyond the top edge of the said casing f.
The rotating or revolving movement is imparted to the conveyer or screw
proper g, in the example shown in Fig. 2 by the employment of an especial
driving wheel k, though it will be clear that I may, within the limits of my
invention, vary the construction of the driving gear of the conveyer, as also the
special arrangement of the parts, without departing from the principle of my
said invention.
In the said example of Fig. 2 the said driving wheel k is arranged to revolve
upon the axle 1, located as shown in the frame or casing f of the conveyer,
said axle being provided or combined with a cog-wheel m. The said cog-wheel m
will, as is clear, transmit the motion of the driving-wheel by aid of a second
cog-wheel mounted upon a second shaft o, at the other end of the said shaft o
is a cog-wheel 7, engaging with a similar cog-wheel q located at the upper end
of the shaft of the conveyer proper .
The construction and arrangement of the parts will be clear without further
description.
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 corn-ear-conveyer for harvesting-machines the combination of an
harvester with a spiral suitably journaled within a casing and means to rotate
the said spiral for the purpose and substantially as described.
2. A corn-ear-conveyer for harvesting-machines substantially as described in
the accompanying specification and illustrated in the drawing.
