Improvements in or connected with Apparatus for Automatically
Discharging Given Quantities of Seed from Kettles of Seed
Presses and other similar Plant.
I, HERBERT ALEXANDER, of Water Lane, Leeds, in the County of York,
Engineer, do hereby declare the nature of this invention (a communication to
me from abroad by Antoine Emile Kiderlen, of Amsterdam, Engineer),
to be as follows: -
The object of this invention is to construct apparatus whereby given quantities
of seed may be automatically discharged from kettles employed with seed presses
and other similar plant, the said automatic discharge being capable of being
opened or cut off by hand, and the seed being loosened before the commencement
of each series of discharges.
According to my invention, I employ the ordinary measuring box having cut
off slides at top and bottom which are connected to opposite ends of a rocking
arm pivotted on a bracket situated outside the measuring box. A rocking piece, which
may suitably be composed of two plates rivetted together a short distance apart, is
fulcrumed on the bracket, and projecting studs are provided on the said rocking
piece in such a manner that they come in contact with the alternate sides of the
rocking arm allowing an interval between each contact on the rocking piece
being rocked on its centre. The rocking piece is actuated from a crank or cranks
pin situated on the stirrer mechanism, to which it is connected by means of a
connecting rod, or other suitable reciprocation mechanism may be employed.
Where two or more measuring appliances are required to be actuated at the
same time the top and bottom slides are continued on the other measuring
chamber or chambers, thus enabling the same movements to be utilized for two or
more measuring appliances at the same time.
Separate slides are provided to each measuring chamber, so as to enable the feed
to be cut off from one or more chambers at a time at will, and on the end of
the said slides projecting fingers or teeth are provided for the purpose of loosening
the seed at the entrance to the said chambers, thus preventing a feed being choked
through having remained out of action for a short time.

I, HERBERT ALEXANDER, of Water Lane, Leeds, in the County of York,
Engineer, do hereby declare the nature of this invention (a communication to
me from abroad by Antoine Emile Kiderlen, of Amsterdam, Engineer),
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-

The object of this invention is to construct apparatus whereby given quantities
of seed may be automatically discharged from kettles employed with seed presses
and other similar plant, the said automatic discharge being capable of being
opened or cut off by hand, and the seed being loosened before the commencement
of each series of discharges.
In order that my invention may be clearly understood, I will proceed to describe
same with reference to the accompanying drawing, in which similar letters refer
to like parts in all the figures.
"
Figure 1 is a front elevation of a kettle fitted with apparatus constructed
according to this invention, and Figure 2 is a side view partly in section of the
same apparatus. Figure 3 is a plan of the apparatus with the kettle removed.
According to my. invention 1 employ measuring boxes A, having cut off
slides B and C.at top and bottom; the said slides being connected to opposite ends
of a rocking arm D which is pivotted on a shaft E carried on brackets F'.
G.is
a rocking piece which is carried loosely on the shaft E, and H are studs which
project from the sides of the rocking piece G in such a manner that they come
alternately in contact with a rocking arm J, on the rocking piece G being rocked
on its centre. The studs H are adjustably set in concentric slots H¹, in which
they may be set to the right or left for the purpose of extending. or reducing
their throw in either direction. K are, slides which enable one or both of the
chambers to be cut off from the kettle at will, and L are fingers which loosen the
material on the slides being moved thus keeping the entrances to the chambers
clear. The slides K are provided with levers M fulcrumed at N, thus enabling
the said slides to be actuated by hand at any required time. The rocking piece G
is actuated from a suitable crank or wheel (not shewn in the drawing), to which
it is connected by means of the connecting rod P.
When the apparatus is at work, the connecting rod P' actuates the rocking
piece G in such a manner as to cause the studs H to come alternately in contact
with the opposite ends of the rocking arm J, thus causing the shaft E to rock with
an interval of rest between each rocking movement. The rocking of the shaft E
rocks the rocking arm D, with the result that the slides B and C are
moved so as to open the inlet and close the outlet simultaneously, and then to
close the inlet and open the outlet simultaneously; and this action continues so long
as the apparatus is at work. Should it be desired to use one measuring box only,
the slide of the other measuring box is actuated, thus cutting, off the supply
from the kettle at entrance to the box.
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. The rocking piece G having studs H on same, in combination with the
rocking arm I substantially as and for the

page_text: 2. The rocking piece G having studs H on same, the latter being adjustable for
the purpose of adjusting the throw and the duration of the interval between the
throws of the slides B and C, in combination with a rocking lever actuating
slides B and C, substantially as and for the purposes set forth.
3. The combination of the measuring boxes A, slides B and C, rocking arm D,
shaft E, rocking piece G, studs H, rocking arm J, slides h, fingers L, levers M and
connecting rod P, substantially as and for the purposes set forth.
