PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Weighing Granular and other
Materials.
I, MICHAEL EDUARD REISERT, of the firm of Hennefer Maschinenfabrik at Hennef
on the Sieg, in the Empire of Germany, Engineer do hereby declare the nature of
this invention to be as follows:-
"My invention relates to that class of automatic weighing apparatus in which the
receptacle for receiving the material to be weighed empties itself by tilting and more
especially to the weighing apparatus as described in the specification of former
Letters Patent No. 7554 A.D. 1886 and the object of my said invention is to provide
means for reducing the vibrating (tilting) movement of the weighing receptacle to
the least possible degree and in consequence thereof to avoid shocks or other
disturbances of the working parts of the scale when tilting.
Heretofore the filling and emptying of such tilting receptacles in automatic scales
was effected through the same opening which requires for entire emptying a con-
siderable oscillating motion from the one extreme position of the receptacle to the
other. This however will cause shocks and sometimes other disturbances in the
working parts of the apparatus which can be advantageously avoided by diminishing
the angle of the oscillation to the smallest possible degree practicable.
To effect this my improved weighing receptacle is provided with separate openings
for the reception of the material to be weighed as for the emptying of the same and
the shape of the receptacle and its position in the scale is so arranged that, while
the material to be weighed enters into the upper part of the said openings the
bottom of the receptacle is in a horizontal or nearly horizontal position. The lower
opening permitting the emptying out of the material after the latter has reached
its proper weight is arranged next to the said bottom of the receptacle in a wall,
the lower edge of which forms the upper edge of this lower opening. This upper
edge is at such a vertical distance from the bottom of the receptacle and in the
horizontal direction so far apart from the outer edge of the same, that the material
during the supply period will in no case reach to the said horizontal edge of the
bottom of the receptacle, even if the inclination of the heaped up material outside
of the said opening and the wall aforesaid has attained its utmost limit.
Although the arragement of my improved receptacle as above described would fully
answer the purpose above mentioned I sometimes make use of a sort of flap bearing
against or near the outer edge of the horizontal bottom of my tilting receptacle in
order to prevent single particles of the granular material to be weighed from escaping
accidentally over the said outer edge of the bottom. This flap is however adapted in
such a manner that when the receptacle tilts for emptying it automatically opens until
it reaches a position perpendicular to its pivot and thus allowing the material to be
discharged without obstruction.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Weighing Granular and other
Materials.
I, MICHAEL EDUARD REISERT, of the firm of Hennefer Maschinenfabrik, at Hennef
on the Sieg, 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 that class of automatic weighing apparatus-in which the
receptacle for receiving the material to be weighed empties itself by tilting; and
more especially to the weighing apparatus as described in the specification of former
Letters Patent No. 7554 .A.D.. 1886; and the object of my said.invention is to
provide means for reducing the vibrating or tilting movement of the weighing
receptacle to the least possible degree and in consequences thereof to avoid shocks or
other disturbances of the working parts of the scale-when tilting.
Heretofore the filling and emptying of such tilting receptacles in automatic scales
has been effected through the same opening which requires for entire emptying, a
considerable oscillating motion from. the one..extreme position of the receptacle to the
other. This however will cause shocks and sometimes other disturbances in the
working parts of the apparatus which can be advantageously avoided by diminishing
the angle of the oscillation to the smallest possible degree.practicable.
In order to make my invention more clearly understood I will describe it with
reference to the accompanying drawings, in which
Figures 1, 2 and 3 are-side elevations of a weighing, apparatus: embodying my
invention; thermoving parts.in cache figure being in different positions to botter
illustrate the-operation of my invention.
..
A is the scale beam, B the receptacle. for receiving the material to be: weighed ;
C the weight. The material to be weighed enters through the whopper Daintol the
receptacle B; which, when exactly filled empties itself automatically: In the mean-
time the supply of material.is entirely stopped... The regulation of the supply from
the hopper and the operations of the weighing receptacle are: effected by such
mechanism which are well known and do not form the object of my present inventions
The angles of oscillation of my improved receptacle which will exceed very little only
the angle of the natural scope of the heaped-up: material, is determined by means
of the studs e e¹ hearing respectively against the suspension rod E in the extreme
positions of the receptacle.
My improved weighing receptacle B is provided with separate: openings 0/0 for:
ŕthe reception of the material to be weighed as for the emptying of the same, andathe
shape of the receptacle and its position. in the scale is soarranged that, whilenthe
material to be weighed enters through the upper opening 0 of the receptacle the bottom W
of the latter is in a horizontal or nearly horizontal position (Figures 1and 2). The
lower opening Opermitting the emptying out of the material after the latterthass
reached its proper-weight, is narranged next to the bottom of the receptacle in a
wall S, the lower edges of which forms the upper edge of this lower opening >01.
This upper edge s is at such a vertical distance. from the bottom. W of the receptacle
and in the horizontal direction so far apart from the outer edge W₁ of the same,
that the material' during its supply-period will in no case reach to the said horizontal
edge Weven if the inclination of the heaped up material outside of the opening and
the wall S has attained its utmost limit.
Although the arrangement of my improved receptacle as above described would
fully answer the purpose above mentioned, I sometimes make use of a sort of flap K
bearing by its dead weight against or near the outer edge W of the horizontal
bottom of my tilting receptacle, in order to prevent single particles of the granular
material to be weighed from escaping accidentally over the outer edge W1 of the
bottom. This flap K is however adapted in such a manner that when the receptacle B

page_text: tilts for emptying, it automatically opens (Figure 3) until it reaches a position
perpendicular to its pivot & and thus allowing the material to be discharged without
obstruction.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-.
First. In combination with an automatic weighing apparatus a tilting receptacle B,
provided with an upper opening O for entering and a separate lower opening Oi
for discharging the material and having its bottom W with overflow edge W
horizontally or nearly horizontally arranged when the material enters into the
receptacle, substantially as and for the purpose set forth.
Second. In an automatic weighing apparatus the combination of the weighing
receptacle B having openings and O₁ separated by the wall S with a flap K
pivoted at substantially as and for the purpose specified.
