PROVISIONAL SPECIFICATION.
Improvements in Machines for Delivering and Weighing Corn and
other Grain.
I, THOMAS STEVENS of the Ceres Iron Works, Kingston-on-Thames, in the
County of Surrey Engineer do hereby declare the nature of this invention to be as:
follows:-
The object of my invention is to provide machines which will supply grain from
a hopper to a weighing machine, and so continuously to weigh off sacks of corn or
seed. For this purpose and according to my invention I connect the hopper to the
weighing machine by a standard extending from the frame of the weighing
machine to the hopper, and preferably this standard is connected to the
weighing machine between the weighing platforms, by which means I combine in
one and the same machine a hopper and a weighing machine. The machine is
mounted on wheels and can be moved from place to place as may be required like.
an ordinary sack weighing machine.
There is provided a slide or valve regulated by trip gear which closes the valve
and cuts off the supply of grain immediately the correct weight is delivered to the
bag or box as the case may be.
Machines constructed according to my invention can be moved along under the-
shoots from the granary as may be required, with the utmost facility.
Dated this 23rd day of September 1891.

COMPLETE SPECIFICATION.
Improvements in Machines for Delivering and Weighing Corn and
other Grain.
I, Thomas STEVENS, of the Ceres Iron Works, Kingston-on-Thames, in the
County of Surrey 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 :-
The object of my invention is to provide machines which will supply grain
from a hopper to a weighing machine and so continuously to weigh off sacks
of corn, seed, or other grain. For this purpose and according to my invention I
connect the hopper to the weighing machine by a standard and connections
extending from the frame of the weighing machine to the hopper, and preferably
this standard is connected to the weighing machine between the weighing
platforms; by such means I combine in one and the same machine a hopper and a
weighing machine.
In the accompanying drawings I have shown by way of example a construction
of such a combined apparatus according to my invention, Figure 1 thereon being a.
sectional side elevation, Figure 2. a partial front elevation of the hopper, and
Figure 3 a vertical section through the closing mechanism of the hopper, drawn to
a somewhat larger scale than the previous figures, in all of which latter similar
letters of reference hereinafter quoted indicate like parts.
A is the hopper supported by standards B B from the frame of the weighing
machine, the mechanism of which latter may be of usual or convenient construction..
CC are the weighing platforms; the machine may be mounted on wheels, say such

page_text: as are shown at D, and can be moved from place to place as may be required like
an ordinary sack weighing machine. The hopper A is provided with a spout A¹
as at Figures 1 or 3, and the said hopper receives its supply of corn or malt from,
say, an upper floor or overhead shoot as indicated at E, Figure 1. F is a
guillotine slide for closing the spout A', F¹ being a knob or handle on the slide,
the shank of which is adapted to be grasped or held by a detent arm G swinging
from pin G¹.
HH are pillars from the grain weighing platform, and H¹ is the sack supporting
bar. J shows a sack in position being filled. Downward motion of the grain
weighing platform is communicated to the detent arm G by suitable connections so
that the latter is drawn towards the right hand and releases the slide F at the time
the said downward motion of the platform takes place, and I have found the
following connection to be suitable, as shown at Figure 2, where K is a cord or
chain connected at one end to the detent G, passing over pulley Kband fixed at
the other end to a rod K* carried by one of the pillars H, the said rod K' being
adjustable so as to enable the detent to be operated at any desired position of the
weighing platform.
The action is as follows: the slide F being open, the grain runs through the
spout A', and immediately the correct weight is in the sack J, the slide is
automatically released; the sack is then removed and the operation repeated.
Machines constructed according to my invention can be moved along under the
shoots from the granary as may be required, with the utmost facility.
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. In machines for weighing corn and other grain, the combination with a
weighing machine of a hopper and feed spout, the latter being automatically closed
by the descent of the grain weighing platform, whereby a sack placed upon the
platform may be filled up to a predetermined weight and the supply then
mechanically stopped, all substantially as herein described and illustrated with
reference to the accompanying drawings.
2. In machines for weighing corn and other grain, the combination_with_a
weighing platform C and a hopper, of a closing slide F and connections K K K²
to the aforesaid weighing platform, all substantially as herein shown and
described.
3. The general arrangement of machine for delivering and weighing corn and
other grain to sacks, all constructed, arranged, and acting substantially as herein
described with reference to the accompanying drawings.
Dated this 23rd day of June 1892.
