Improvements in Corn-feeders for Threshing Machines.
I, IWAN GOLWER, of 81, Romanowstrasse, Riga, in the Empire of Russia,
Machinery Expert, 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 has for its object a corn feeder for threshing machines by means
of which the corn is automatically and in one operation raised from the ground
on to the machine and introduced into the corn feed drum. In threshing
machines it would be easy to effect the introduction by means of an introducer
arranged longitudinally with the machine, but for the grain collecting device and
one end, and the straw ejecting device at
the steam engine at the
SO that only the
the other end, which stand in the way of this,
longitudinal side of the machine can be considered. In the apparatus herein-
after described the arrangement is such that the wheat or corn conveyed from
the ground on to the machine by means of an inclined endless band, or the like,
reaches a shaking device forming the actual feeder which alters the direction of
movement of the corn, and effects the correct introduction or insertion of the
same.
In the accompanying drawings,
Figure 1 is a plan view of the feeder;
Figure 2, a side view of the same;
Figure 3, a section on the line CD of Figure 1;
Figure 4, an end view of the feeder;
Figure 5, a section on the line A B of Figure 6;
Figures 6 shows the arrangement of the feeder from which it is evident how
the alteration of the direction of movement of the corn proceeds.
As shown in Figures 1 to 4, the feeder consists of an endless band or the like a
provided with conveying devices, which band is carried over rollers and 61
which are mounted in bearings c and c³, and of a corn shaker q over which the
upper end of the endless band projects, so that the corn conveyed by the latter
falls on the shaker. f is the opening to the drum which corresponding to the
mounting of the drum t lies at right angles to the longitudinal axis of the
machine.
The feeder shown in Figures 1 to 4 has downwardly inclined tracks w wo¹
arranged on both sides of the drum opening, which tracks are preferably provided
5 with an edge r. The endless band and the corn shaker may be operated in various
ways, for instance in the apparatus shown in Figures 1 to 4, the driving takes
place from a pulley by means of a belt which is carried over guide rollers 111
and a pulley. The latter is mounted on the shaft g. The shaking movement
of the corn shaker is produced by means of a cam wheel and a catch y y¹
0 bearing thereon, these catches acting on bars on which the corn shaker
suspended. The bars are pivotally mounted on cross bar e mounted in
bearings c. If then the corn be directly conveyed from the ground d¹ on to the

page_text: endless band a, this band will convey the corn upwards and throw it on the
inclined tracks wwwhich, in consequence of their inclination and turn, forward
the mass into the drum opening f altering the direction of movement crosswise,
as shown in Figure 1, the corn stalks being turned on their centres by the shaking
of the inclined track ww so as to progressively take up the positions 1, 2, 3, in
the last of which positions they fall through the opening f. In the modification
shown in Figures 5 and 6 a single inclined track w is shown mounted to one
side of the opening f on a rod 2 which is pivoted on a post u, the track w being
further supported by small rollers s. The rod is connected by a link el with
the pulley in such a way as to impart to the track the necessary shaking.
movement. In this arrangement the stalks instead of being turned on their
centres as shown in Figure 1, are turned on one of their ends so as to take up
the successive positions 1, 2, 3 as shown in Figure 6.
The driving may of course be effected by means of a crank gearing or by any
suitable arrangement and also the shape of the inclined track or guide surface
may be made in various ways. In the feeder shown in Figures 1 to 4, two end-
less bands a may of course be employed arranged one at each side of the machine.
In the case of the one-sided feeder shown in Figure 6, two such feeders must be
provided if it is desired to use two endless bands one on each side.
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. A feeder for corn or the like for threshing machines characterised by the
corn or the like, which is lifted on to the machine by means of an inclined end-
less band (w), being conveyed onto a guide surface (4) having a shaking motion,
the direction of the corn being altered in consequence of the shape of a surface
or track (w) and thrown through the insertion opening parallel to the axis of
the threshing drum, substantially as described.
2. A form of construction of the corn feeder hereinbefore described in which
the guide surface (7) is arranged in such a way on one or both sides of the
insertion opening that the corn when slipping down on the surface either turns
endwise or swerves on the centre substantially as described.
3. A form of construction of the corn feeder herein before described in which
the guide surfaces (w w¹) of the shaker (g) lie on both sides of the feed opening,
characterised by a feed band (a) being employed on each side of the threshing
machine, substantially as described.
