Improvements in Broad-cast or similar Sowing Machines.
I, WILLIAM DAVIDSON of Mills of Clola, Mintlaw in the County of Aberdeen,
Miller, do hereby declare the nature of this invention to be as follows:-
This invention relates to machines for sowing grain on to land and it has for its
object to ensure even distribution of the grain.
The improved machine is formed with cross boxes and is carried by a framing
on running wheels after the fashion of a broad-cast sowing machine. The boxes
which are light and shallow and may be of approximately rectangular cross section
are supplied with the grain from a large hopper placed centrally so as to deliver
it to both. In each box is fitted an endless band formed with projecting boards
or buckets, the bands being carried around pulleys on vertical shafts and being
arranged to travel horizontally on edge over the bottom of the boxes. Along one
side of the bottom board of each box a series of holes or outlets is formed for the
discharge of the grain, the size of opening being regulated by shutter bars. The
bands are driven from the running wheels each of which is provided with a separate
running axle terminating at and supported by suitable bearings near the centre.of
the framing and each having a bevel wheel on its inner end gearing with a bevel
pinion on an upright shaft. The upper end of each upright shaft terminates in one
of the grain boxes and is fitted with a wheel or pulley over which the travelling
and distributing band passes.
In the operation of the machine the grain delivered from the central hopper is
carried to right and left along the bottom of the respective boxes by means of the
projections on the travelling bands, part of the grain falling through the delivery
holes. The surplus grain is carried round the ends of the boxes and brought back
along the other side towards the centre where it is delivered to an elevator which
raises it into the hopper, the elevator being operated from the running wheels.
The travelling bands may be replaced by rotating screws in which case the boxes
are made of trough shape to fit the screws.

1, WILLIAM DAVIDSON of Mills of Clola, Mintlaw, in the County of Aberdeen,
Miller, 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 machines for sowing grain on to land and it has for its
chiect to ensure oven distribution of the grain.

page_text: The invention is illustrated by the accompanying drawings, Figure 1 being a
plan and Figure 2 a vertical section in the direction of the axle of the sowing
machine.
The improved machine is formed with cross boxes A and is carried by a framing B
on running wheels C after the fashion of a broad-cast sowing machine. The boxes A
which are light and shallow and may be of approximately rectangular cross section
are supplied with the grain from a large hopper D placed centrally so as to deliver
it to both. In each box A is fitted an endless band E formed with projecting
boards or buckets F, the bands E being carried around pulleys G on vertical
shafts Hand being arranged to travel horizontally on edge over the bottom of the
boxes A. Along one side of the bottom board of each box a series of hales or
outlets H' is formed for the discharge of the grain, the size of opening being
regulated by shutter bars capable of movement in any ordinary manner.
bands E are driven from the running wheels C each of which is provided with a
separate running axle I terminating at and supported by suitable bearings J near
the centre of the framing B and each having a bevel wheel K on its inner end
gearing with a bevel pinion L on an upright shaft M. The upper end of each
upright shaft M terminates in one of the grain boxes A and is fitted with a wheel
or pulley N over which the travelling and distributing band E passes.
In the operation of the machine the grain delivered from the central hopper D
is carried to right and left along the bottom of the respective boxes A by means
of the projections F on the travelling bands E, part of the grain falling through
the delivery holes H. The surplus grain is carried round the ends of the boxes
and brought back along the other side towards the centre where it is delivered to
an elevator O which raises it into the hopper D, the elevator O being operated
from the running wheels C by a pinion P.
The travelling bands E may be replaced by rotating screws in which case the boxes
are made of trough shape to fit the screws.
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 :-
The improved broad cast or similar sowing machine constructed and arranged to
operate substantially as described.
