Improvements in Thrashing Machines.
1, THOMAS BEE, of Stamp End Works, Lincoln in the County of Lincoln, Principal
Foreman of Messrs. Clayton and Shuttleworth's Thrashing Machine Department do
hereby declare the nature of this invention to be as follows:-
.
This invention has for its object to simplify and cheapen the construction of
thrashing machines and likewise to render them more compact.
To this end the shogging board and shakers are combined and are actuated from
one shaft or set of cranks instead of from separate shafts and cranks as heretofore.
The shogging board has its bottom made of corrugated iron, or other material,
which affords channels having a smoother surface than wood, and enables the chaff to
fall with a less inclination of the surface than usual.
The shakers are fork teeth, by preference of wood, mounted in rows on shafts
carried on the shogging board. The shafts have each a slotted arm working over an
adjustable pin attached to the side of the machine for altering the throw of the forks
so that they may make a more or less oblique angle with the horizontal. Each shaft
with its arms is counter-weighted. When the shogging board is reciprocated, the
forks are set in vibration, which causes the straw to be tossed up while it is carried
forward by the blast from a fan working overhead, the grain and chaff falling down
through angular laths and inclined steps on to the shogging board bottom which
consists of corrugated iron or other suitable material as referred to above.
Thrashing machines according to this invention may be variously modified,
particularly as regards the agitator, without departure from the essential principles of
the invention.

COMPLETE SPECIFICATION.
Improvements in Thrashing Machines.
1, THOMAS BEE, of Stamp End Works, Lincoln, in the County of Lincoln, Principal
Foreman of Messrs. Clayton and Shuttleworth's Thrashing Machine Department, 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 to simplify and cheapen the construction of
thrashing machines having fork straw shakers and likewise to render such machines
more compact. To this end the shogging board and straw shakers are combined and
are actuated from one crank shaft instead of from separate crank shafts as heretofore.
The shogging board has its bottom made of material such as corrugated iron that will
afford channels having a smoother surface than wood, and will enable the chaff to fall
.with a less inclination of the surface than usual.
The shakers are fork teeth, by preference of wood, mounted in rows on shafts
carried on the shogging board. The shafts have each a slotted arm working over an
adjustable pin attached to the side of the machine and which can be set nearer to or
further from the fork shaft for altering the throw of the forks for the purpose of
giving a more or less violent agitation to the straw. Each arm is also adjustable on
its fork shaft, so as to give the forks a more or less oblique angle with the horizontal.

page_text: suakers are set in vibration, when
causes the straw to be tossed up while it is carried forward by the blast from a fan
working overhead, the grain and chaff falling down through angular laths and over
inclined steps on to the shogging board bottom which consists of corrugated iron or
other suitable material as referred to above.
Thrashing machines according to this invention may be variously modified, without
departure from the essential principles of this invention. For example although in
the accompanying drawings two cranks are shewn on the shaft for working the
shogging board and shakers in some cases one crank might suffice or more than two
might be used.
In the accompanying drawings,
Fig. 1 is a vertical section on the line C D Fig. 2.
Fig. 2 is a sectional plan; and
Fig. 3 is a cross section on the line A B Fig. 1 of so much of a thrashing machine
as is necessary to illustrate this invention.
Figs. 4 and 5 are respectively side and end elevations to a larger scale showing
details of adjustment.
1 is the shogging board having a bottom 2 made of corrugated metal such as iron
having the upper corrugated surface quite smooth so as to enable the chaff
to fall with a less inclination of the surface than usual. This shogging board is
carried by spring hangers 1 so that it can be caused to reciprocate longitudinally
between the side frames 3 of the thrashing machine; it is actuated from a shaft 4 by
two cranks 4ª and two connecting rods 4º. 5, 5 are shakers consisting of fork teeth
arranged in rows, the teeth in each row being carried by a cross bar or shaft 6, that
is mounted at its ends in the sides of the shogging board so as to be capable of partial
rotary motion and is provided with a counterweight 7. Each cross bar or shaft 6
extends through a slot 6ª in one of the side frames 3 and has fixed to it an arm &
formed with a slot 9 into which extends a pin 10. In the example each arm 8 is
formed with a hole and with a longitudinal slit and is clamped to the shaft 6 by
bolts 8 so that the arm can be adjusted in order to admit of adjustment as required.
Each pin 10 is adjustably attached to the side of the machine for the purpose of
altering the throw of the forks so as to give a more or less violent agitation to the
straw. 11, 11 are laths arranged a short distance apart and extending across the
shogging board from side to side, with their upper surfaces inclined to the horizontal.
12, 12 are plates with inclined steps, carried by the laths 11. 13 is a fan. With the
arrangement described, when the shogging board is reciprocated by the cranks 4" and
connecting rods 4b, the arms 8 will be rocked about the pins 10, and the shafts 6 and
forks 5 caused to vibrate from the positions shewn in full lines in Fig. 1 to those
shewn in dotted lines, and thus to toss or agitate the straw while it is carried forward
by the blast of air produced by the fan 13 as well understood. The grain and chaff
fall between the plates 12 and laths 11 on to the corrugated bottom 2 of the shogging
board and pass away in the usual manner.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a thrashing machine the combination of fork shakers with a shogging board
so that they can be worked by one crank or by a set of cranks on a single shaft
instead of by independent cranks.
"
2. In a thrashing machine having
a "fork shaker the use of an adjustable pin for
altering the throw of each set of fork teeth independently so as to give a more or less
violent agitation to the straw.
3. In a thrashing machine of the kind referred to, constructing the shogging board
with a smooth corrugated bottom, of material such as iron the grooves of which run
longitudinally for the purpose specified.

page_text: 4. In a thrashing machine, the combination and arrangement of parts hereinabove
described with reference to the drawings annexed.
