Improvements in Machinery for Weighing Grain and other Granular
Materials.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23 Southampton Buildings, in the
County of Middlesex, Patent Agent, do hereby declare the nature of this invention,
a communication to me from abroad by Etienne Rondony, Louis Rondony, and
Jean Rondony, all of 80 Cours Vitton, Lyons, in the Republic of France, to be
as follows:-
.
The apparatus constituting the object of the present application is intended for
the weighing of grain and other granular materials at the moment of placing them
in the sack; it is arranged in such manner that the delivery of the materials into
the sack is interrupted as soon as the desired weight is obtained and commences
again as soon as the sack has been changed, by simply operating a handle.
Sheet I of the accompanying drawings shows the application of the invention
with a simple steel yard.
Figures 1 and 2 are vertical sections and Figure 3 is a horizontal section.
The steel yard, which is of ordinary construction, is composed of a beam with
two arms H oscillating upon centres d, d, and supporting on one side, the sack
holder G, and on the other side, the weights hung upon the rod e.
This steel yard is enclosed, together with the other parts of the apparatus, in a
case A, and has on the exterior a graduated scale I, upon which is moved the
moveable weight f for the small sub-divisions, as shown in Figure 3.
The case A is suspended by loops and hooks a underneath the hopper B, which
contains the grain; this latter runs through the flexible tube C into the com-
partment D of the case, and passes into the passage E, whence it falls into the
sack F..
The entrance to the passage E can be closed by a shutter b hung upon a
quadrant keyed upon a transverse shaft K, which by means of two toothed
wheels h, h, receives motion from a second shaft L, which carries a handle M on
the outside of the case. Upon the shaft L is fixed a cam N provided with a
notch, limiting the movement of the shaft by bearing to the right or to the left
against a fixed stop n. The cam N has a tooth i which catches in an indent j
upon a pawl or stop lever O when the handle M is pressed down.
The longer arm of the steel yard H carries a pin j which passes through a ring p
fixed to a lever R centred at K; the lever R is connected by the rod S to an
arm P centred at 1; the connections are so made that a slight movement of the
steel yard produces a much greater movement of the extremity r of the arm P,
which bears upon an inclined plane m of the pawl or stop lever O.
The weight of the parts is so arranged that the extremity r has a tendency to
descend along the inclined plane.
The tooth which catches against the other side of the pawl or stop lever O, is
so shaped that it only holds when the extremity of the arm P, having remounted
the inclined plane m, holds the pawl or stop lever O against the cam N. This is
what takes place during the act of weighing, as shown in Figure 1, when the
weights hung upon the rod e, not yet being balanced by the weight in the sack, hold
the steel yard and the lever R down, and consequently the arm P at the top of its
course. In this position the shutter b is open and the grain runs into the sack.
As soon as the weight in the sack is sufficient, the longer arm of the steel yard
rises, as also the lever R, and the extremity r of the arm P descending the inclined
plane m, frees the pawl or stop lever O; the weight of the shutter & then acting

page_text: upon the inclined tooth i, presses back the pawl or stop lever and the shutter falls.
thus closing the passage for the grain, as seen in Figure 2.
At the end of this movement, an elastic arm T fixed to the shaft L presses upon
the lever R, which it has pressed down, so as to leave the steel yard free; the pin j
then playing freely in the ring p, the steel yard takes its position of equilibrium
and the weighing may be verified.
The sack can: hen be removed and replaced by an empty sack, the handle M is
then pressed down, which lifts the shutter and replaces all the parts in the position
shown in Figure 1.
In Sheet II of the drawings, Figures 4 and 5 shown an analogous arrangement
with a compound steel yard.
The weighing apparatus is composed of a beam H carrying the sack F by the
hook m and acting by the loop or connection U upon a second transverse beam V,
which carries cutside the case A the pan e for the weights.
The case A is hung by hooks and loops a before the hopper containing the grain.
This latter passes through C into the compartment D, the lower opening of which
leading to the sack, is closed by the swing shutter b carried by a lever g keyed
upon the transverse shaft L.
This shaft, provided on the exterior with a handle M, carries a cam N, which
acts as before described by means of the pawl or stop lever O and the arms or
levers R and P, which are connected together by the rod S.
The lever R is held down by the transverse beam V until the balance is obtained,
then it is allowed to rise and at the same time the extremity of the arm P rises
upon the inclined plane of the pawl or stop lever O and permits it to release the
cam N which allows the shutter to fall. By pushing down the handle M the
apparatus is put in condition to weigh another sack.
It should be understood that the invention is not confined to the exact arrange-
ments of apparatus above described, but that various modifications can be made
without departing from the peculiar character thereof.

COMPLETE SPECIFICATION.
Improvements in Machinery for Weighing Grain and other Granular
Materials.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23 Southampton Buildings, in the
County of Middlesex, Patent Agent, do hereby declare the nature of this inven-
tion, a communication to me by Etienne Rondony, Louis Rondony, and Jean
Rondony, all of 80 Cours Vitton, Lyons, in the Republic of France, and in what
manner the same is to be performed, to be particularly described and ascertained, in
and by the following statement, reference being had to the drawings accompanying
my Provisional Specification
;-
The apparatus constituting the object of the present application is intended for
the weighing of grain and other granular materials at the moment of placing them
in the sack; it is arranged in such manner that the delivery of the materials into
the sack is interrupted as soon as the desired weight is obtained, and commences
again as soon as the sack has been changed by simply operating a handle.
Sheet I shows the application of the invention with a simple steel yard.
Figures 1 and 2 are vertical sections and Figure 3 is a horizontal section.
The steel yard, which is of ordinary construction, is composed of a beam with
two arms H oscillating upon centres d, d, and supporting on one side the sack
holder G and on the other side the weights hung upon the rod e.
This steel yard is enclosed, together with the other parts of the apparatus, in a

page_text: case A, and has on the exterior a graduated scale I, upon which is moved the
moveable weight for the small sub-divisions, as shown in Figure 3.
The case A is suspended, by loops and hooks a, underneath the hopper B, which
contains the grain; this latter runs through the flexible tube C into the com-
partment D of the case, and passes into the passage E, whence it falls into the
sack F.
The entrance to the passage E can be closed by a shutter hung upon a
quadrant keyed upon a transverse shaft K, which, by means of two toothed
wheels h, h, receives motion from a second shaft L, which carries a handle M on
the outside of the case. Upon the shaft L is fixed a cam N provided with a
notch, limiting the movement of the shaft by bearing to the right or to the left
against a fixed stop n. The cam N has a tooth i which catches in an indent j
upon a pawl or stop lever O when the handle M is pressed down.
The longer arm of the steel yard H carries a pin J, which passes through a
ring p fixed to a lever R centred at K. The lever R is connected by the rod S
to an arm P centred at 1; the connections are so made that a slight movement of
the steel yard produces a much greater movement of the extremity r of the arm P,
which bears upon an inclined plane m of the pawl or stop lever O.
The weight of the parts is so arranged that the extremity has a tendency to
descend along the inclined plane.
The tooth, which catches against the pawl or stop lever O, is so shaped that it
only holds when the extremity of the arm P, having remounted the inclined
plane m, holds the pawl or stop lever O against the cam N. This is what takes
place during the act of weighing, as shown in Figure 1, when the weights hung
upon the rod e, not yet being balanced by the weight in the sack, hold the steel
yard and the lever R down, and consequently the arm P at the top of its course.
In this position the shutter b is open and the grain runs into the sack.
As soon as the weight in the sack is sufficient, the longer arm of the steel yard
rises, as also the lever R, and the extremity of the arm P descending the inclined
plane m, frees the pawl or stop lever O; the weight of the shutter b, then acting
upon the inclined tooth i, presses back the pawl or stop lever and the shutter falls,
thus closing the passage for the grain, as seen in Figure 2.
At the end of this movement, an elastic arm T fixed to the shaft L, presses upon
the lever R, which it has pressed down, so as to leave the steel yard free; the
pin J then playing freely in the ring p, the steel yard takes its position of
equilibrium and the weighting may be verified.
The sack can then be removed and replaced by an empty sack, the handle M is
then pressed down, which lifts the shutter and replaces all the parts in the position
shown in Figure 1.
In Sheet II of the drawings, Figures 4 and 5 show an analogous arrangement
with a compound steel yard.
The weighing apparatus is composed of a beam H carrying the sack F by the
hooks m, and acting by the loop or connection U upon a second transverse beam V,
which carries outside the case A, the pan or plate e for the graduated weights.
The case A is hung by hooks and loops a before the hopper containing the
grain. This latter passes through C into the compartment D, the lower opening
of which, leading to the sack, is closed by the swing shutter & carried by a lever g
keyed upon the transverse shaft L.
This shaft, provided on the exterior with a handle M, carries a cam N, which
acts as before described, by means of the pawl or stop lever and the arms or
levers R & P, which are connected together by the rod S.
The lever R is held down by the transverse beam V until the balance is obtained,
then it is allowed to rise, and at the same time the extremity r of the arm P rises
upon the inclined plane of the pawl or stop lever O and permits it to release the
cam N, which allows the shutter to fall. By pushing down the handle M, the
apparatus is put in condition to weigh another sack.

page_text: It should be understood that the invention is not confined to the exact arrange.
ments of apparatus above described, but that various modifications can be made
without departing from the peculiar character thereof.
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 combination of shutter b, cam N, pawl lever O, and levers R and P, the
lever P being held down by the weights which serve for the weighing, and, in rising
at the moment of equilibrium, determining the fall of the shutter, which stops the
entrance of grain into the sack.
2. The combination with the parts above mentioned, of the exterior handle M
which replaces everything in position for the next weighing.
