PROVISIONAL SPECIFICATION left by the said Charles Green at the Office
of the Commissioners of Patents on the 25th March 1882.
CHARLES GREEN of 51 Ripon Street in the city of Lincoln Machine Maker
AN IMPROVED METHOD OF MAKING BEATER BARS FOR THRASHING MACHINES
This invention relates to an improvement in the method of constructing the
beater.bars of thrashing machines.-As hitherto made the surface of, these bars has
been provided with diagonal corrugations leaning to the right or to the left, and
they have been placed round the drum alternately ie with one bar with corru-.
gations leading to the right and the other with corrugations leading to the left
being made thus alternately to provide for spiral action guiding the corn fed into
the drum all to one end. With such bars it is necessary to feed the corn over the
whole length of the drum which requires some skill and experience on the part of
the feeder. In my invention I make the corrugations incline both to the right
and left starting with a V shape in the centre of the length of the bar the point
of the V coming forward in the direction in which the drum travels. There are
two advantages in this
First I use only one beater or bar instead of two
Second The corn may all be fed on to the centre of the drum which is an
easier place on which, to put it, and the inclination of the corrugations divides it
automatically and spreads it equally over all the surfaces towards the ends.
Another point froin the employment of this bar, is, that the edge of it not only'
feeds on to the top of the iron or wooden bar to which it is attached, but also
reaches some distance say an inch down the front of the said part. This mode
of construction has two advantages It makes the attachment much more secure
and considerably increases the wearing surface

CHARLES GREEN of 51 Ripon Street in the City of Lincoln Machine Maker
AN IMPROVED METHOD OF MAKING BEATER BARS FOR THRASHING MACHINES
This Invention relates to an improvement in the method of constructing the
beater bars of Thrashing machines.
As hitherto made the surface of these bars has been provided with diagonal
corrugations leaning to the right or the left, and they have been placed round the
drum alternately i:e: with one bar with corrugations leading to the right and the
other with corrugations leading to the left, being made thus alternately to provide
for spiral action guiding the corn fed into the drum all to one end.
With such bars it is necessary to feed the corn over the whole length of the
drum which requires some skill and experience on the part of the feeder.
In my Invention I make the corrugations of each bar incline both to the right
and left starting with a V shape in the centre of the length of the bar, the point of
the coming forward in the direction in which the drum travels. There are two
advantages in this :-
.
First I use only one pattern beater or bar instead of two.
Second; The corn may all be fed onto the centre of the drum which is an easier
place on which to put it and the inclination of the corrugations divides it
automatically and spreads it equally over all the surfaces towards the ends.
Another point as an improvement in this bar is that the present edge of it not
only feeds on to the top of the iron or wooden bar to which it is attached but also
reaches some distance, say, half an inch down the front of the said part.
This latter mode of construction has two advantages :-It makes the attachment
much more secure and considerably increases the wearing surface.
The Invention is clearly shown on the accompanying drawings. Figure 1 is a
partial plan view showing the ribs A. A arranged to the right and to the left from
the centre B, the two centre ribs forming a V with its point looking in the
direction of the drum's rotation.
Figure 2 shows the bar C in section with the lip piece D set against the front of
the wooden (or it may be iron) batten or stretcher E for attachment to the drum F
as shown at Figure 3.
The under surface of each bar C may be flat or it may be hollowed out as in the
sectional view Figure 4.
I purpose fitting six of said bars C to the drum F as shown but any other
number may be fitted according to circumstances, each bar being arranged around
the drum that any one of them can be readily removed when desired.
Having now described the nature of my said Invention and in what manner
the same is to be performed I declare that I claim :-
The manufacture and employment of beater bars for Threshing machines
with the ribs arranged from the centre to the right and to the left as
described and substantially as shown in the annexed drawings.
Secondly, I claim-the edge piece or lip D, to set against the front of the
stretcher E as and for the purposes set forth.
In witness whereof I the said Charles Green have hereunto set my hand
and seal this Twenty second day of September in the year of our Lord one
thousand eight hundred and eighty two.
