PROVISIONAL SPECIFICATION.
Improvements in Apparatus Suitable for Weighing, Mixing, and
Bagging Chaff and Grain.
I, PEIRSON TURNER, of 82, Mark Lane, in the City of London, Engineer, do
hereby declare the nature of this invention to be as follows:―
The apparatus forming the subject of this invention is more particularly applic-
able to serving out weighed sacks of forage in establishments where a large
number of horses are kept.
In such establishments the forage often consists of a mixture in definite propor-
tions of chaff and crushed grain such as maize and this mixture is served out to the
employées in sacks each containing the same weight.
The arrangements I adopt in such a case are as follows:-The crushed grain is
contained in a hopper beneath which is a receptacle carried by a weigh beam.
The mouth of the hopper is closed by a valve or pivotted flap connected to the
receptacle in such a manner that when the latter is in its highest position the mouth
is uncovered and when in its lowest position the mouth is covered. The bottom of
the receptable is formed of hinged doors operated as hereinafter described.
The chaff is delivered down a shoot in a continuous stream from the chaff cutting
machines. Beneath the shoot is a second receptacle also carried by a weigh beam
and having hinged doors at its bottom and also near its top. The doors of both
receptacles have brushes at their edges bridging over a gap between them, this
prevents shocks when the doors are suddenly closed and also prevents the forage
from holding them open by jamming between them. The doors have arms fixed
to them which are connected by links SO that the doors of each
pair open and close together and the doors of the second receptacle
are also so connected together that the top ones are closed when the bottom
ones are open and the top ones are open when the bottom are closed. The bottom
doors of both receptacles are operated simultaneously by a sliding bar which is
slotted to receive pins fixed to the arms. The sliding bar has fixed to it notched
plates which when in one position engage with spring bolts on the doors and hold
the latter closed but when in another position the bolts are opposite the notches
so that the doors can be opened. In consequence of the bar being slotted the first
portion of the motion in opening the doors only brings the notches opposite the
bolts whilst the latter portion of the motion pulls the doors open. In closing on
the other hand the first part of the motion carries the plates to the locked position
without moving the doors and the latter part closes the doors the spring bolts
giving way to pass the plates.
The sliding bar is operated by a vertical shaft carried in bearings fixed to the
side of the second receptacle. Fixed to this shaft are two arms or wipers. Parallel
to the shaft on the receptacle are two shafts in a line with each other and constantly
revolving in opposite directions in stationary bearings. Fixed to these shafts
are a pair of pin wheels and when the receptacle is in its highest or lowest position

page_text: the pins on one or other of these wheels come into contact with the wipers turn-
ing the shaft on the receptacle in one or other direction and operating the doors.
The action of this part of the apparatus is as follows:-Assuming both recep-
tacles to have emptied and to be rising from their lowest to their highest positions
then the ascent of the second receptacle brings the upper wiper on its shaft into
the path of the upper pin wheel closing the lower doors of both receptacles and
opening the upper doors of the second receptacle any chaff which has collected on
them falling into the receptacle. The ascent of the first receptacle opens the
valve in its hopper allowing the crushed corn to flow out into it. As soon as the
proper weight has been received the receptacle descends closing the valve and
then it remains in its lowest position. Meanwhile the second receptacle has been
more slowly filling with chaff and when the proper weight has been received the
receptacle descends bringing the lower wiper into the path of the pins of the lower
pin wheel opening the lower doors of both receptacles and closing the upper doors
of the second receptacle and so on.
The material from the receptacles is delivered into two shoots that from the
first being connected at the bottom to the other and being hinged so that its
inclination can be varied to regulate the flow whilst that from the second is pro-.
vided in addition to the usual rotary stirrers with internally projecting pins which
break up the stream of chaff making interstices to receive the crushed corn the
two materials being thus thoroughly and evenly mixed.
The mixture then passes to an inclined pivotted shoot which can be revolved
about a vertical axis so as to bring its lower end over one or other of a number
of holes arranged in a circle in a fixed table. Beneath the table are spouts form-
ing continuations of the holes and provided with the usual appliances for holding
the mouths of the sacks.

Improvements in Apparatus Suitable for Weighing, Mixing, and
Bagging Chaff and Grain.
I, PEIRSON TURNER, of 82, Mark Lane, in the City of London,. 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 apparatus forming the subject of this invention is more particularly applic-
able to serving out weighed sacks of forage in establishments where a large
number of horses are kept.
In such establishments the forage often consists of a mixture in definite propor-
tions of chaff and crushed grain such as maize and this mixture is served out to the
employées in sacks each containing the same weight.
The arrangements I adopt in such a case are shown in side elevation at Figure 1,
and in vertical section (on the line 2-2 Figure 1) in Figure 2. The crushed
grain is contained in a hopper a beneath which is a receptacle b carried by a weigh
beam c. The mouth of the hopper is closed by a valve or pivotted flap d connected
to the receptacle by the rod d in such a manner that when the latter is in its
highest position the mouth is uncovered and when in its lowest position the mouth
is covered. The bottom of the receptacle is formed of a hinged door e operated
as hereinafter described.
The chaff is delivered down a 'shoot f in a continuous stream from the chaff

page_text: cutting machines. Beneath the shoot is a second receptacle g also carried by a
weigh beam and having hinged doors jj at its bottom and also other doors k k
near its top. The doors of both receptacles have brushes at their edges bridging
over a gap between them, this prevents shocks when the doors are suddenly closed
and also prevents the forage from holding them open by jamming between them.
The doors have arms el fixed to them which are connected by links so that
the doors of each pair open and close together and the doors of the second recep-.
tacle are also so connected together by links that the top ones are closed when
the bottom ones are open and the top ones are open when the bottom are closed.
The bottom doors of both receptacles are operated simultaneously by sliding
bars m which are slotted to receive pins fixed to the arms. The sliding bars have
fixed to them notched plates m¹ shown in local inverted plan and elevation and
to a larger scale at Figures 3 which when in one position engage with spring bolts
on the doors and hold the latter closed but when in another position the bolts are
opposite the notches so that the doors can be opened. In consequence of the bars m
being slotted the first portion of the motion in opening the doors only brings the
notches opposite the bolts whilst the latter portion of the motion pulls the doors
open. In closing on the other hand the first part of the motion carries the plates
to the locked position without moving the doors and the latter part closes the doors
the spring bolts giving way to pass the plates.
The sliding bars m are operated by a vertical shaft o carried in bearings o¹ fixed
to the side of the second receptacle. Fixed to this shaft are two arms or wipers o².
Parallel to the shaft o on the receptacle are two shafts pp in a line with each
other and constantly revolving in opposite directions in stationary bearings p
Fixed to these shafts are a pair of pin wheels and when the receptacle is in
its highest or lowest position the pins on one or other of these wheels come into
contact with the wipers of turning the shaft o on the receptacle in one or other
direction and operating the doors.
The action of this part of the apparatus is as follows: Assuming both recep-
tacles to have emptied and to be rising from their lowest to their highest positions
then the ascent of the second receptacle g brings the upper wiper o² on its shaft o
into the path of the upper pin wheel 2 closing the lower doors of both receptacles
and opening the upper doors of the second receptacle any chaff which has collected
on them falling into the receptacle. The ascent of the first receptacle ỗ opens the
valve & in its hopper allowing the crushed corn to flow out into it. As soon as
the proper weight has been received the receptacle descends closing the valve d
and then it remains in its lowest position. Meanwhile the second receptacle g
has been more slowly filling with chaff and when the proper weight has been
received the receptacle descends bringing the lower wiper 2 into the path of the
pins of the lower pin wheel p² opening the lower doors e and j of both receptacles
and closing the upper doors of the second receptacle and so on.
The material from the receptacles is delivered into two shoots qr that from the
first being connected at the bottom to the other and being hinged so that its
inclination can be varied to regulate the flow whilst that from the second is pro-
vided with the usual rotary stirrers which break up the stream of chaff making
interstices to receive the crushed corn the two materials being thus thoroughly
and evenly mixed.
The mixture then passes to an inclined pivotted shoots which can be revolved
about a vertical axis so as to bring its lower end over one or other of a number of
holes arranged in a circle in a fixed table t. Beneath the table are spouts u form-
ing continuations of the holes and provided with the usual appliances for holding
the mouths of the sacks.
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. The combination of two receptacles on weigh beams, a door at the bottom of

page_text: one and means for cutting off the supply to it when it descends, doors at the top
and bottom of the other, and means whereby the descent of the second operates
all the doors.
2. The combination of the shaft on the second receptacle, the arms on it and the
two pin wheels revolving in opposite directions.
3. The combination of the notched plates m' and spring bolts on the doors.
4. The means for operating the doors substantially as described and illustrated
in the drawings.
5. Apparatus for weighing and simultaneously delivering two charges substan-
tially as described and illustrated in the drawings.
6. The combination of the pivotted shoot and perforated table.
7. Apparatus suitable for weighing mixing and bagging chaff and grain sub-
stantially as described and illustrated in the drawings.
