I, WILHELM HENNEBERG, of N° 15 Friederich Strasse, Gotha, in the German
Empire, Engineer, do hereby declare the nature of my invention for "APPARATUS
FOR REGULATING THE SUPPLY OF GRAIN OR OTHER GRANULAR OR PULVERULENT
MATERIAL TO MILLING AND OTHER MACHINERY to be, as follows:-
"
My invention relates to apparatus for the automatic regulation of the discharge
of grain or other granular or pulverulent material from the hoppers of milling
and other machinery in order to prevent the over-filling or running empty of the
hopper and the obstruction of the connecting spouts, in consequence of the supply
of material to the hopper not being perfectly uniform. For attaining this end,
I make use of the varying weight of the material in the hopper to effect the
automatic enlargement or diminution of the feeding opening.
The apparatus is composed, as the accompanying drawing shews, of two sheet
iron plates (A and B), the upper one, (A,) of which, is inclined about 45 degrees
and is fitted with two pivots supported at the points (a) these being in such &
position, that the plate forms a lever of unequal arms. The lower plate (B) hangs
on the upper one in hinges (b) and can swing between the fixed pins (c, d,) as well
as be lifted and lowered by the turning action of the upper plate. The movableness
of the lower plate may be diminished by increasing its weight or by acting upon it
by a spring. The more or less sensitive action of the upper plate may be regulated
by the spring (e) and its motion is limited by the screw (f) and by the pin (g).
An essential condition is, that the centre of the pivot (a) and the centre of the
hinge (b) shall be in one and the same horizontal line when the hopper is empty.
A cast iron frame consisting of two plates (C) and two connecting pieces (D and E)
supports the sheet iron plates which are fitted in between. By this arrangement
the apparatus is rendered capable of being applied to any existing hopper.
When the hopper is empty the lower plate touches the feeding roller (F) nearly,
so that on the material first entering, it is retained in the hopper. But when the
material rises to a certain height, the lower plate is moved away from the pin (c)
and the feeding begins (Position I). From the time when the lower plate touches
the pin (d) the feeding opening will be constant until the material rises in the
hopper to such a height that the upper plate begins to turn. This turning effects
a lifting of the lower plate and consequently an enlarging of the feeding opening
(Position II). This will increase until the material ceases to rise.

I, WILHELM HENNEBERG of 15 Friedrich Strasse, Gotha in the Empire of
Germany, Engineer, 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 :-
My invention relates to apparatus for the automatic regulation of the discharge
of grain or other granular or pulverulent material from the hoppers of milling and
other machinery in order to prevent the overfilling or running empty of the hopper
and the obstruction of the connecting spouts in consequence of the supply of
material to the hopper not being perfectly uniform. For attaining this end, I make
use of the varying weight of the material in the hopper to effect the automatic
enlargement or diminution of the feeding opening.
Referring to the drawings filed with my Provisional Specification, it will be seen
that the apparatus is composed of two sheet iron plates (A and B) the upper
one (A) of which is inclined about 45 degrees and is fitted with two pivots
supported at the points (a) these, being in such a position, that the plate forms a
lever of unequal arms. The lower plate (B) hangs on the upper one in hinges (b)
and can swing between the fixed pins (c, d) as well as be lifted and lowered by the
turning action of the upper plate. The moveableness of the lower plate may be
diminished by increasing its weight or by acting upon it by a spring. The more
or less sensitive action of the upper plate may be regulated by the spring (e) and
its motion is limited by the screws (f) and by the pin (g). An essential condition
is, that the centre of the pivot (a) and the centre of the hinge (b) shall be in one
and the same horizontal line when the hopper is empty. A cast iron frame
consisting of two plates (C) and two connecting pieces (D and E) supports the
sheet iron plates which are fitted in between. By this arrangement the apparatus
is rendered capable of being applied to any existing hopper.
When the hopper is empty, the lower plate touches the feeding roller (F) nearly,
so that on the material first entering, it is retained in the hopper. But when the
material rises to a certain height, the lower plate is moved away from the pin (c)
and the feeding begins (Position I). From the time when the lower plate touches
the pin (d) the feeding opening will be constant until the material rises in the
hopper to such a height that the upper plate begins to turn. This turning effects
a lifting of the lower plate and consequently an enlarging of the feeding opening
(Position II). This will increase until the material ceases to rise.
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, in respect of apparatus for regulating the supply of grain or other granular
or pulverulent material to milling and other machinery is:
The use in combination with a feed hopper, of two regulating plates connected
together by hinges, the upper plate being inclined at an angle of about 45° to the

page_text: horizontal when the hopper is empty, and capable of being moved upon a horizontal
axis. by the pressure of the grain to an extent limited by two stops, one of which
is adjustable, while the lower plate is slightly inclined to the vertical when the
hopper is empty and is capable of being moved laterally between two stops by the
pressure of the grain, such lower plate being raised or lowered by the movement
of the upper plate so as to automatically increase or decrease the discharge opening
of the hopper, substantially as herein described.
