I, WILLIAM BRENTON, of Polbathic, St. Germans, in the County of Cornwall,
Agricultural Engineer, do hereby declare the nature of this invention to be as
follows:-
-
My invention relates to machines for drilling seed and manure and especially
to machines for drilling seed and manure simultaneously, the object of my inven-
tion being to provide improved means for covering the manure prior to the sowing
of the seed or vice versa in order to prevent the manure from coming into direct
contact with the seed.
My improved device, which is arranged between the coulters, comprises two
discs either flat or dished mounted on axes inclined to each other in such a manner
that as the discs travel forward their back edges lift the soil and throw it into the
channel formed by the preceding drill coulter.
Although I have described my invention as applied to a drill for sowing manure
and seed simultaneously it is to be understood that it is also applicable to drills
for sowing seed or manure separately..

Improvements in or connected with Agricultural Drills.
I, WILLIAM BRENTON, of Polbathic, St. Germans, in the County of Cornwall,
Agricultural 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:
-
My invention relates to machines for drilling seed and manure and especially
to machines for drilling seed and manure simultaneously.
The object of my invention is to provide improved means for covering the
manure prior to the sowing of the seed or vice versa in order to prevent the
manure from coming into direct contact with the seed, and it comprises an
improved device, which is arranged between the coulters, and has two discs either
flat or dished mounted on axes inclined to each other.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing which represents in perspective view a
CD

page_text: drag bar of a drill provided with two coulters between which my improved
covering device is arranged.
In this figure a is the drag bar which is hinged or pivoted to the frame of the
machine, is the manure coulter, c is the seed coulter and d, d are the covering
discs which discs are mounted on axes at the two ends of the fork e which is
fixed to the drag bar a between the coulters b, c, the said axes being arranged at
an angle to one another so that the discs are wider apart on their leading edges
than at the rear edges. As shown the said discs are of concavo-convex shape the
concave sides being towards one another but if desired plain discs may be used.
It will be understood that as the apparatus travels forward the back edges of
the discs lift the soil between them and throw it into the channel formed by the
preceding drill coulter, the drill coulter which is arranged behind the discs
forming its own channel into which the seed is deposited.
Although I have described my invention as applied to a drill for sowing manure
and seed simultaneously it is to be understood that it is also applicable to drills
for sowing seed or manure separately in which case the covering device would be
arranged behind the coulter in conjunction with which it was used. Or, as is
obvious, it can be used for forming a ridge where ridges for agricultural purposes
are required.
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 covering or ridging device composed of two discs mounted in a suitable
standard and arranged at an angle to each other, substantially as, and for the
purposes, described.
2. In an agricultural drill the combination with manure and seed coulters of a
covering device arranged between the seed coulters, substantially as described and
illustrated in the accompanying drawing.
