Improvements in Apparatus relating to the Filling and Weighing of
Sacks of Grain.
I, GEORGE INSKIPP, of 5, Bedford Row, London, Architect, 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 relates to improvements in apparatus for use in filling sacks
with malt, grain and the like, and has for its object to provide a means by which
such sacks may be supplied with the material in the exact quantity required.
In carrying out my invention a hopper is employed through which the malt or
grain passes to a sack or other container suitably arranged to stand upon a weigh-
ing device.
The hopper terminates with a funnel and the passage of grain through
this funnel is checked or closed by means of two gates placed horizontally and
sliding partly over each other when the passage is being closed. These gates slide
in grooves and the edges which over-lap are formed with a notch or notches at
the centre. When the gates are entirely drawn back the grain is free to flow un-
checked, rapidly filling the sack or container.
When the sack becomes nearly full and it necessary to check to a nicety the
balance of grain required to make the full complement of weight, the gates are
moved forward towards each other by means of a series of levers which operate
simultaneously through the agency of a handle. When the two gates overlap
only for a small distance, the notches form an opening of small size, which by
further operating the handle before mentioned, diminishes the opening until the
same is entirely closed and the grain supply shut off.
This device allows the sack to be operated very accurately as only a very small
stream of grain is supplied during the last few moments when the sack is nearly
full weight, and immediately the accurate weight is registered the operator closes
the gates and cuts off the supply.
In order that the invention may be more clearly understood, reference is had
to the accompanying sheet of drawings, in which Fig. 1 is a section of the lower
part of the hopper provided with my improved apparatus, Fig. 2 is a section at
right angles to Fig. 1, Fig. 3 is a plan of part of the apparatus, Fig. 4 is a similar
view showing the gates partly open, and Fig. 5 is a detail view.
A is the hopper, at the lower end of which is the square frame B forming part
of the framing of the hopper and the upper part of the passage leading froin it.
To the lower end of this frame the plate C is fixed, and to the plate the flanged
metal shute C¹ is bolted continuing the passage from the hopper. The plate and
metal frame are formed with the channels cand c¹, the former being wider than
the latter, so as to overlap it. The channel c¹ is formed by a rib inside the shute.
Within these channels the plates or gates D and D¹ are placed, the former fitting
into the upper channel and resting upon the top of the flange. The channels form
The
guides which ensure the gates working freely and overlapping each other.
gates are provided with the lugs d to which the levers E are attached through the
links e.
The levers E are operated by the lever F carried by the spindle f which

page_text: is provided with the handle f' at one side of the apparatus. The levers E and F are
connected by the links el and the parts are arranged so that on pulling the handle
in either direction, the gates are withdrawn or closed simultaneously. When
closed to extent shown in Fig. 4 the notches in each of the gates form a central
opening through which the grain passes in a small stream
Fig. 5 shows in detail view a catch for holding the gates in position, which
consists of a pin G, provided with the spiral spring g and carried by the bracket gl.
The lower end of the pin is rounded and projects into the depression d² in
one of the gates. The latter can thus be held in the position shown in Fig. 4
until the full quantity of malt has been supplied, a further movement of the handle
shutting off the supply completely..
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
-5.
(1) In an improved apparatus for supplying malt and other grain to sacks, the
combination with a suitable hopper or shute from bin or store of two sliding gates
fitted to the said shute notches in the said gates forming a contracted passage,
and levers for operating the same substantially as described and for the purposes
specified.
(2) In an improved apparatus for supplying malt and other grain to sacks, the
combination with a hopper, of a metal shute fixed to the lower end of the said
hopper, and two guides one wider than the other, of two gates fitted in the said
channels, notches in the said gates and levers connected to each gate withdrawing
and closing the same simultaneously, substantially as and for the purposes specified.
(3) In an improved apparatus for supplying malt and other grain to sacks, the
combination with a hopper, of a passage or opening at the lower end of the hopper,
a metal plate fixed to the wooden frame of the hopper, a flanged metal shute secured
to the plate, and guides in the plate and metal frame, of two sliding gates fitting
in the said channels, a notch in each gate forming a contracted passage, levers con-
nected to each gate, a handle operating the said levers, and a catch securing the
gates in position, substantially as described and shown in the accompanying
drawings, and for the purposes specified.
