Improvements in or relating to Apparatus for Automatically Weigh
ing Grain and Granulated or Powdered Substances.
I, RICHARD SIMON, of Zulla Road, Nottingham, in the County of Nottingham,
Engineer, do hereby declare the nature of my said invention to be as follows:-
This invention has for object the construction or arrangement of certain
appliances or apparatus by which after a sack or tilt pan is suspended from a band
ring, or the like, two valves can be opened, by hand, in a hopper or shoot, and
grain or other substances allowed to fall through, said band ring and sack or
pan being otherwise in equilibrium with a scale plate of a balance beam.
Above the band ring is another ring or plate resting on stops and guided by
the frame, and capable of being raised vertically by the determined weights put
upon the scale plate and engaging a clip or claw to hold one of the valves open,
the other being closable by a toggle joint lever due to its own weight when
released.

Improvements in or relating to Apparatus for Automatically Weigh
ing Grain and Granulated or Powdered Substances.
I, RICHARD SIMON, of Zulla Road, Nottingham, in the County of Nottingham,
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:-
This invention has for object, the construction or arrangement of certain appli-
ances or apparatus by which after a sack or tilt pan is suspended from a band ring,
or the like, two valves can be opened by hand in a hopper or shoot, and grain or
other substances allowed to fall through into the sack or pan, this being otherwise
in equilibrium with a scale plate of a balance beam.
Above the band ring is another ring or plate resting on stops and guided by
the frame, and capable of being raised vertically by the determined weights put
upon the scale plate and engaging a clip or claw to hold one of the valves open,
the other being closable by a toggle jointed lever due to its own weight when
released.
The invention will be clearly understood by reference to the annexed drawings,
Figure 1 side elevation, Figure 2 front elevation.

page_text: A is an equal armed beam having its knife edges all in one plane. B is the
weight scale carrying the standard weights C. D is the scale at the other end of
the beam, formed like a trunk to which the empty sack has to be attached by
means of the band or strap E and locking lever for securing the mouth of a sack
open with rapid action. F is the inlet from above for corn etc.
G, H, are shutters closing the inlet and K is the handle by which these shutters
are opened and held in that position by the steel nose I gearing into K, K.
L, L, weights resting on the beam until held by suitably placed studs marked
in the descent of the beam. M, small equalizing or compensating weights.
N, stay. P, stop. R, counter.
In practice, a labourer attaches an empty sack to the trunk D by means of the
band or belt E and then pulls the handle K to open the shutters and locks them
in that position (I into K K). The grain now flows from the inlet F direct into the
sack, and its weight, together with that of the weights L, L, causes a gradual
descent of the sack until, in about 7 seconds from the handle being pulled, the
beam has travelled far enough for the catch K K to release the nose I on the
outer shutter which nearly closes by its own weight. The grain continues to
enter but only through two dribble holes in the inner shutter until in another 7
seconds, and when the exact weight is in the sack the outer valve becomes com-
pletely released by the descent of the beam from a suitably arranged catch on the
trunk D which holds it open the further entrance of grain is entirely prevented
until the attendant, having removed the full sack and having attached another
empty one, has again pulled down the handle K.
it will be understood that an empty sack similar to those being filled is first
put on the scale B.
Each sack hangs in equilibrium when full, so that its accurate weight may be
seen at a glance.
Each time a sack is filled, the counter records one, so that miscounts cannot occur.
All wearing surfaces are of extra tool steel hardening.
To ensure accuracy, the machine in the usual manner of such is tested full and
empty by the inspector of weights and measures before stamping.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :--
The construction and arrangements of the parts constituting the machine as
represented on the annexed drawings.
