Improv
Substances.
I WILLIAM BEILBY AVERY of 124 Digbeth, Birmingham, in the County of
Warwick, Machine Maker, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide a simple and compact machine for the
weighing of grain and other substances, and the invention consists in a novel arrange-
ment of parts whereby this object is effected.
To this end I secure above an opening in the floor, or in any other convenient
position, a rectangular frame of metal, which is provided with a bridge piece which
carries a suitably shaped hopper provided with an inclined shoot.
Supported by the frame is an arrangement of compound levers composed of
rectangular frames, between which the measuring vessel is supported in any con-
venient manner. Attached to an arm or projection of one of the levers is a weight,
the stem of which projects upwards, and actuates a gate carried by a rock lever
pivotted to the frame, and which serves to close the opening of the shoot when the
desired quantity of grain has been allowed to flow through into the measuring vessel.
The measuring vessel is divided into two parts by a central vertical partition, and is
provided at bottom with a pair of doors, which open inwards alternately, the opening
of the doors being effected automatically as the levers rise under the influence of the
contents of the measuring vessel.
By this means I am enabled to obtain a compact and simple apparatus for auto-
matically weighing grain and other materials, either into sacks or in bulk.

page_text: Improvements in Machinery for Weighing Grain and other
Substances.
I WILLIAM BEILBY AVERY of Digbeth, Birmingham in the County of Warwick,
Machine Maker, 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:-
The object of the present invention is to provide a simpic and compact machine for
automatically weighing grain and other substances and delivering the same either
into sacks or other packages or into bulk as may be thought desirable.
In the accompanying drawings I have shewn various views of my improved con-
struction of weighing machine.
Fig. 1 being a front elevation and
Fig. 2 a plan view the supply hopper being removed in order that it may not
obstruct the view of the parts beneath.
Fig. 3 is an elevation of the left hand side of Fig. 1 and
Fig. 4 is a similar view of the right hand side of Fig. 1.
The machine is shown as fitted above a rectangular opening in the floor of a
granary but it will be obvious that it may be readily adapted to other situations as
may be found desirable.
AA is a rectangular metal frame which is bolted or otherwise secured to the floor
and to this frame are bolted two vertical bridge frames B B one on either side, these
frames being connected together by a bridge or crosspiece CC, which carries a supply
hopper D and a spout or shute c for delivering the grain to the weighing apparatus
from the hopper.
EE is a rectangular box or receptacle for containing the grain to be weighed and
this box or receptacle is divided into two compartments by a transverse vertical
partition each compartment being provided with a balanced tilting bottom or door ee¹
supported on centres e²e. These tilting bottoms are severally connected on either
side of the box by means of link rods to rock levers ee mounted on opposite
ends of a rock shaft which extends across the box E E' and projects through either
side thereof. Secured upon the rock shaft e in the plane of the division plate or
partition is a leaf or flap e which serves to deflect the stream of corn from the shute c
into one or other of the compartments of the box E E' as will be hereinafter more
fully explained. FF are a pair of levers one on either side of the hox or re-
ceptacle E E which are connected together by cross bars ff so as to form a
rectangular frame. These levers are carried by and have their fulcra on knife edges
in the links pendent from the bridge C. The shorter arms of these levers are
provided with links into which take hooked brackets ** secured to the right
hand side of the box E E. The cross bar which connects the longer arms of the
levers F F is provided with a tail ƒ from the extremity of which is suspended by
means of a rod g the counterbalance weight G.

page_text: HH are a second pair of levers one on either side of the box E E¹ having their
fulera in the links which may be secured to the frame A or to the floor-These
levers H H are connected together at their opposite ends so as to form a rectangular
frame (like the levers FF) by cross bars and are also respectively connected to
the levers FF by means of the links 22. At the ends opposite to their fulera these
levers H H carry links h³ ³ into which take hooked brackets attached to the left
hand side of the receptacle E E.-The arrangement of levers F and H as described
forms a compound lever which surrounds and supports the box E E'. By this
arrangement of apparatus the parallel motion of the box is ensured and a simple and
compact weighing machine of great strength is produced.
The rod by which the weight G is suspended from the tail of the levers F is
extended upwards and is connected by a link or loop to a tail formed at one end of a
rocking frame I. This frame is mounted on a rock shaft I* which has its bearings in
the side frames B B and at its opposite end is provided with a curved shutter or gate į
which serves to close the mouth of the shute c of the hopper D.
In order to retain the tipping bottoms of the receptacle E E' in a closed position
during the filling operation I provide a locking device composed as follows:-
On the side of the receptacle E E' is fixed a plate J. This plate is provided with
two sockets which serve to carry a sliding bolt . The lower socket is prolonged
and turned down as shown in the drawings Fig. 1 to form a bracket in which is
pivotted a weighted lever one end of which is pivotted to the lower end of the
sliding bolt j.
The weighted end of the lever works or moves in a link frame or stirrup k
adjustably fixed on the underside of the rectangular frame A of the machine or in any
other convenient position.
The rock lever et on the end of the rock shaft e is fitted with a quadrant shaped
plate e having at each corner a notch into one or other of which the upper end of
the sliding holt j¹ takes alternately.
Now supposing the supply hopper D to be filled with grain and that a sufficient
quantity has passed out through the shute e to nearly fill the compartment E¹ of the
receptacle E E the parts will be in the position shewn in the drawings that is to say
the receptacle E E will have descended nearly to its lowest position the counter-
balance weight C will be raised and the shutter or gate i will have closed the shute c.
A small quantity of grain will however be allowed to trickle through a small opening c¹
on the underside of the shute or in the gate or shutter in order to make up the
required quantity of grain in the receptace E E-When this is effected the receptacle
will make a further movement downwards to its lowest position. As the receptacle
makes it final descent the weighted end of the lever will come in contact with the
bottom of the stirrup k and will withdraw the locking bolt from the notch in the
plate e. The tipping bottom of the full compartment will now be free to rock or
tip under the weight of the grain contained therein and will thereby discharge its
load. At the same time the lever e will be rocked on its shaft by the opening of the
door and will tilt over the leaf e' so as to direct the grain from the shute e into the
empty compartment of the receptacle which will then be filled and discharged in
the same manner. This operation will be continued, the compartments E and E¹
being alternately filled and emptied as long as the hopper D is supplied with grain.
It will be evident that if desired any suitable counting mechanism may be adapted
to the improved weighing machine and also that the various details of construction
may be more or less modified without departing from the object of my invention
which is obtain a compact apparatus for weighing grain and other substances.
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 :-
1st. The apparatus for weighing grain and other substances constructed, arranged
and operating substantially as herein shown and described.
2nd. In apparatus for weighing grain and other substances the combination of a
weighing receptacle with a compound lever as and for the purpose set forth.

page_text: 3rd. In apparatus for weighing grain and other substances in which the material to
be weighed is delivered from a shoot or spout connected with a hopper suitably
arranged in relation to the weighing mechanism the combination with a compound
lever carrying a weighing receptacle and a counterweight, of a lever, as I carrying a
gate or shutter i for closing the delivery shoot or spout substantially as herein shown
and described.
4th. In apparatus for weighing grain and other substances the combination with a
weighing receptacle containing two compartments which are alternately filled and
emptied of the means substantially as herein shown and described for alternately
locking an unlocking the movable bottoms of the compartments as and for the purpose
set forth.
