Year: 1884

page_text: We WILLIAM BROWN and HENRY MACDONNELL both of Stockton on Tees in the
County of Durham and THOMAS THOMPSON and RICHARD EMBLETON both of South
Stockton in the North Riding of York do hereby declare the nature of said
Invention for "IMPROVEMENTS IN APPARATUS FOR AUTOMATICALLY MEASURING
AND MIXING GRAIN OR OTHER MATERIALS to be as follows:-
"
An apparatus constructed according to our Invention consists of a casing which
is provided with a hopper the said casing forming the frame of the apparatus.
The internal construction is such that on grain or other material to be measured
being poured into the hopper or receiver it passes through the apparatus and
issues therefrom accurately measured in quantity. When required the apparatus
will also mix different qualities or kinds of grain or other materials in definite
proportions.
The hopper or receiver is provided with fixed or moveable division plates forming
several separate compartments or small hoppers of equal or different sizes into each
of which separate compartments or small hoppers may be poured a different
description of grain or other material. They are provided with moveable bottoms
or shutters constructed to slide in or out as required to admit prevent or control
the flow of the grain or other materials from the divisions or hoppers above to a
measure revolving below the said small hoppers in the shell or casing of the
machine. The sliding bottoms or shutters may be drawn in or out independently
and thus afford the great advantage of controlling the supply of grain or other
materials at any time without necessitating the stoppage of the machinery.
The revolving measurer is supported and caused to revolve by any suitable
means. It is provided with concentric plates or projections forming parallel
grooves or spaces corresponding to the openings leading from the compartments or
small hoppers above; and each said groove or space so formed is divided into
segunental sections forming separate receivers boxes or measures into which the
grain or other material is received as it falls from the divisions or small hoppers
above. The revolving measurer is so fitted into the shell or casing in which it
revolves as to leave no passage between the measurer and the shell or casing for
the grain or other materials to pass unless the measurer be made to revolve
although the passages leading from the divisions or small hoppers above be wide

page_text: open.
When the measurer is rotated the boxes or measures thereof continuously
present themselves opposite the openings from the compartments or small hoppers
above and are filled and then continuously discharge their contents to suitable
conveyers or apparatus used in mixing the particular materials operated upon. As
each division or small hopper with its sliding shutter or bottom corresponds to a
separate series of boxes or measures on the revolving measurer the construction of
our machine enables an accurate measure to be taken of the quantity of material
discharged from any particular compartment or small hopper independently of the
quantity of material discharged through the other divisions or small hoppers and
thus the proportionate quantity of each description of material or grain delivered
through the revolving measurer is as well known as the total quantity so operated
upon.
The grain as it falls from the measures may be caused to impinge against dash
slides and wings so that all the descriptions of grain or other materials are
thoroughly mixed when so desired.

We WILLIAM BROWN, HENRY MACDONNELL both of Stockton on Tees in the
County of Durham and THOMAS THOMPSON and RICHARD EMBLETON both of. South
Stockton in the North Riding of York do hereby declare the nature of said
invention for "IMPROVEMENTS IN APPARATUS FOR AUTOMATICALLY MEASURING
AND MIXING GRAIN OR OTHER MATERIALS" and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
An apparatus constructed according to our Invention consists of a casing which
is provided with a hopper or receiver, the said casing forming the frame of the
apparatus-The internal construction is such that on different descriptions of grain
or other material to be measured being poured into the hopper or receiver, they
pass through the apparatus and issue therefrom accurately and separately measured
in quantity When required the apparatus will also mix different qualities or kinds
of grain or other material in definite proportions.
And in order that our said Invention may be fully understood we will now
proceed particularly to describe the same and for that purpose shall refer to the
accompanying drawings in which like Figures of reference are employed to indicate
corresponding parts in all the Figures.
·
Figure 1 represents in plan and Figure 2 in vertical section taken on line X X of
Figure 1 a machine or apparatus constructed according to our Invention Figure 3
represents a front elevation of the apparatus and Figure 4 a transverse section
taken on the line Z. Z of Figure 3.
A hopper or receiver A is secured to or forms part of the casing B which
constitutes the frame of the apparatus and contains a revolving measurer C. fixed
on a spindle D capable of being rotated by any suitable means. In the lower part
of the casing B are provided when required dash boards or dash wings as at E for
mixing the different qualities or kinds of grain or other material as they are
discharged from the measurer C.
In order that the revolving measurer C. may accurately measure the grain or
other material supplied to it from the hopper receiver A we provide the said
measurer with concentric plates c¹ constructed so as to revolve with an accurate
fit in the circular part of the casing B in the manner shown in Figure 4. and to
form parallel grooves or troughs around the measurer C. as shown in Figure 2,.
between these concentric plates c¹ ribs or projections care provided; so that each
groove or trough is divided into a series of segmental sections forming boxes or
receivers as shown in Figure 4, the edges of the ribs or projections c² and of the
plates c¹ being concentric and so fitting the cylindrical surface of the casing B that
grain or other similar material cannot pass between the said edges and the casing.
The distance between every two consecutive ribs or projections c³ dividing the
parallel grooves or troughs of the revolving measurer into boxes must be pitched
to suit the extent of the cylindrical surface of the casing B so that the passage
between the revolving measurer C. and the casing B is closed in one direction
before it is opened in the other, and grain or other material can only pass through
the apparatus when the measurer C. revolves and successively presents its boxes or
receivers to the throats or passages leading from the hopper or receiver A, and
turns then down to discharge their contents into the lower part of the apparatus.
Between the hopper or receiver A and the revolving measurer C division
plates b¹ are provided fixed into or forming part of the casing B and corresponding
in position to the concentric plates c¹, their edges being curved to fit them, the
division plates b¹ divide the neck of the apparatus between the hopper or receiver A
and the revolving measurer C into throats or passages each throat or passage acting
as a feeder to a separate series of boxes or receivers on the revolving measurer C.
as shown in Figure 2-The flow of grain or other material through each throat or

page_text: passage is controlled by a door or shutter a³ each of which can be slidden in or
out independently of the other shutters or doors, so that the flow of grain or other
material through any particular throat or passage can be controlled at will without
affecting the flow through the remaining throats or passages, and the whole amount
of grain or other material passing through the apparatus can be increased or
reduced in definite proportions by opening or closing the said throats or passages
by means of the said doors or shutters-Consequently if several machines
constructed according to our Invention be used to supply one mill, each machine.
or apparatus may be used to measure a different description of grain and supply a
greater or less quantity as may be desired-When several descriptions of grain or
other material are supplied to one machine or apparatus to be accurately and
separately measured we divide the hopper or receiver A into compartments by
means of partition plates a¹ which may be fixed to or form part of the sides of the
hopper or receiver A or may be made to slide in or out in a manner similar to the
doors or shutters a² each partition plate a¹ sliding in or out independently of
the rest so that by drawing out one or more partition plates two or more
compartments can be thrown into one, the partition plates a¹ must-correspond in
position with the division plates 61 and concentric plates c¹ as shown in Figure 2
so that the compartments formed by them also correspond to the throats or
passages leading to the revolving measurer C, and to the separate series of boxes
or receivers to which they act as feeders-By supplying different descriptions of
grain or other materials to different compartments they are delivered to different
series of boxes or receivers of the measurer C. and are thus separately measured
In order to avoid the jamming or shearing effect produced by the ribs or
projections c suddenly presenting their edges to the corresponding edge of the
curved surface of the casing B the surface of this casing which does not face the
edges of the concentric plates c' is made to deviate from the circle in the manner
distinctly shown in Figure 4, the deviation being greater or less according to the
size of the grain or other material passing through the apparatus thus the deviation
would be greater for maise than for wheat-We also prefer to bevel the backs of
the ribs or projections c³ as shewn in Figure 4-The dash boards or dash wings E
may be fixed in suitable positions and converging towards each other at such angles
that the grain or other material as it is discharged from the revolving measurer C
impinges upon them and is thrown off so as to become intermixed as it is being
conveyed away from the lower part of the apparatus.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is:-
An apparatus for automatically measuring and mixing grain or other materials
consisting of a hopper or receiver (divided or not into separate compartments) in
communication with throats or channels capable of being regulated, and supplying
the grain or material to a rotary measurer, provided with boxes or receivers which
receive, measure, and discharge the grain or material (upon dash boards or wings
or not) the said apparatus being constructed or arranged substantially as described
with reference to the accompanying drawings.
