We, DANIEL BELCHER and RICHMOND AND CHANDLER LIMITED, of Southall
Street, Manchester, in the County of Lancaster, Agricultural Implement Manu-
facturers, do hereby declare the nature of this invention to be as follows:―
Our invention relates to improvements in seed drilling machines and consists
of an improved combination and arrangement of parts by which the operator
can at will cause the distribution of seed to instantly and entirely cease by
simply compressing or otherwise actuating a spring lever placed in a convenient
position on one handle of the drill.
To effect this the seed delivery spout is mounted on pivots or otherwise suitably
mounted so as to be capable of being swivelled or moved into and out of its
working position and it is normally held in its working position by the spring
lever so as to allow of the free passage down it of seed from the hopper. The
delivery spout is made of suitable form so that when the spring lever is actuated
the discharge aperture in the hopper or sced receptacle is entirely closed by the
spout and will remain closed until the spring lever is released when the spout
at once automatically resumes its working position in which it remains until -
the spring lever is again actuated.
The hopper or seed receptacle is provided with means such as the ordinary
regulating slide controlled by an adjusting screw for regulating the quantity of
seed sown.

Improvements in Seed Drilling Machines.
We, DANIEL BELCHER and RICHMOND AND CHANDLER LIMITED, of Southall
Street, Manchester, in the County of Lancaster, Agricultural Implement Manu-
facturers, 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:-

working position and it is normally held in its working position by the spring
lever so as to allow of the free passage down it of seed from the hopper.
delivery spout is made of suitable form so that when the spring lever is actuated
the discharge aperture in the hopper or seed receptacle is entirely closed by the
spout and will remain closed until the spring lever is released when the spout
at once automatically resumes its working position in which it remains until
the spring lever is again actuated.
The hopper or seed receptacle is provided with means such as the ordinary
regulating slide controlled by an adjusting screw for regulating the quantity of
seed sown.
In the accompanying two sheets of drawings
Fig. 1 is a side elevation, and Fig. 2 a longitudinal section, on an enlarged
scale, of our improved seed drilling machines.
The seed to be sown is placed in the seed box A and by means of the revolving
brush B (which brush is rotated from the main axle by suitable gearing, not
shown) is propelled through the aperture C in the seed box and the aperture C
in the adjusting slide 1) to the spout E through which it passes to the coulter F
and thence to the drill cut in the ground by the passage of the conlter. The
size of the aperture C may be regulated by hand by means of the adjusting
screw G so as to be adapted to the quantity and size of the seed to be sown, all
in the manner hitherto carried out by us in seed drilling machines of our
manufacture.
According to our improvements we pivot the spout E on a stud H in such a
manner that it can be moved at the will of the operator by means of a con-
necting rod I, spring lever J, and spring K, Fig. 1.
The object of these improvements is to enable the operator of the machine,
at will, to stop the flow of seed to the ground while the machine is moving and
the brush revolving, and for this purpose the spout E is provided with a plate L
which when brought in contact with the adjusting slide D entirely covers the
aperture C and so prevents the escape of seed from the seed box A.
When the operator presses the spring K by means of the spring lever J, the
spout E is caused to partly revolve on its pivot H thus bringing the flat side L
of the spout E into contact with the adjusting slide 1) and entirely covering
and closing the aperture C¹ and on releasing the spring lever J the spring Kй
causes the spout E to immediately resume its original position, i.e. to allow
the passage of the seed through the opening C into the spout E and thence
into the coulter F.
This method of controlling the distribution of seed is applicable to machines
propelled by hand, animal or mechanical power.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is;
-
The combination with the seed box or receptacle and an adjustable slide or
equivalent means for regulating the outflow of the seed, of the movable spout
and connections under the control of the operator for stopping the delivery of
the seed at will and without necessarily stopping the machine, all substantially
as herein set forth.
