PROVISIONAL SPECIFICATION.
Improvements in or connected with Machinery for Drying or
Conditioning Grain.
We, JOSEPH BARRON, Corn Mill Engineer, and SAMUEL KITSON GREEN,
Corn Miller, both of Whitehall Road, Leeds, in the County of York, do hereby
declare the nature of this invention to be as follows:-
Much difficulty has been experienced with machinery for drying or conditioning
grain in regulating the outflow to suit an irregular feed of material to be treated.
It often happens that the material becomes choked in the perforated walls, when
it is liable to become baked; whilst at other times it passes too quickly through
the machine, leaving a portion of the porous walls empty, thereby causing a great
waste of heat and power.
The object of our invention is to construct machinery for drying or conditioning
grain, in such a manner that the flow of grain will be regulated through the machine,
even when the feed is irregular or intermittent.
At the upper part of the machine we pivot two boards or slopes to the sides of
the machine, in such a manner as to form a hopper, their free ends being at the base
of the said hopper, which is situated immediately above an inverted V entrance to
the two perforated walls of the machine. At the lower part of the machine a
division board extends across from side to side, and two flaps or doors similar to
those forming the hopper are hinged at the base of the walls, their free ends resting
against the said division board when they receive an upward pull.
To the inner faces of the hopper and outlet doors, suitable links are attached,
which latter are connected to a rod or rods passing up through the interior of the
machine, in such a manner that on the rod or rods being moved up or down, the
doors of the inlet hopper and those of the outlet are actuated simultaneously.
The vertical rod or rods is or are kept upward by means of springs situated
on a cross beam, or they may be held upward by weighted levers.
As the material is fed to the machine through the hopper its weight opens the
hopper doors in proportion to the amount of feed, and the movement of the said
hopper doors is immediately transmitted to the outlet doors by means of the rods,
which increase or reduce the outlet according to the amount of flow or weight of
material in the hopper, thereby regulating the passage of the material through the
machine in an even and efficient manner.
Instead of having the hopper and outlet doors connected directly to one another,
the outlet doors may have cross pieces attached on their inner sides forming a
crutch within the machine, on which crutch the rod from the hopper doors, or
cross bar at the base of the rod, comes into contact when the rod is moved by the
weight of grain. In this case the outlet doors may suitably be kept up by
adjustable weighted arms connected to the backs of same. By the above
arrangement the lower doors may be opened independently of the hopper doors
and thus the machine may be run empty when not required for use.

Conditioning Grain.
We, JOSEPH BARRON, Corn Mill Engineer, and SAMUEL KITSON GREEN,
Corn Miller, both of Whitehall Road, Leeds, in the County of York, 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 :-
Much difficulty has hitherto been experienced with machinery for drying or
conditioning grain, in regulating the outflow to suit an irregular feed of material
to be treated. It often happens that the material becomes choked in the perforated
walls, when it is liable to become overheated or baked; whilst at other times.it
passes too quickly through the machine, leaving a portion of the perforated walls
empty, thereby causing a great waste of heat and preventing the material being
properly dried.
The object of our invention is to construct machinery for drying or conditioning
grain, in such a manner that the flow of grain will be regulated through the
machine, even when the feed is irregular or intermittent.
In order that our invention may be clearly understood we will proceed to describe
same with reference to the accompanying drawings in which similar letters refer to
like parts in all the figures.
Figures 1 and 2, are respectively side and front elevations of so much of a
machine as is required to illustrate our invention, and Figures 3 and 4, are
respectively longitudinal side and front sections of same.
According to our invention we provide two slopes A, A, which are pivotted
at B, B, at the upper part of the machine, and the two slopes A, A, converge in
such a manner as to form a hopper for the reception of the grain. C, C, are two
perforated walls, the inner sides of which enclose the chamber D which is provided
with an inverted V shaped roof which diverts the feed from the hopper to the
interior of the two perforated walls: E, is a dividing board, and F, F, are outlet
doors which are fulcrumed at G, G, and the said doors are provided with upper
portions H, H, which receive a portion of the weight of the material in the machine.
J, J, are arms which are attached at one of their ends to the doors F, F, and the
free ends of the said arms, connect with a rod K running up through the centre of
the machine. The upper end of the rod K is connected to links L, L, which, are
attached at their opposite ends to the slopes A, A, forming the hopper. It will
thus be seen that the movement of the slopes A, A, regulates the position of the
doors F, F, at the outlet end of the machine. M is a spring which tends to lift
the rod K, the pressure of the spring M being borne by a cross beam. N, and the
pressure of the spring M, may be regulated by the adjusting screw P, situated at
the top of the rod K. R is a casing for preventing the grain from coming into
contact with the arms J and their working parts, and T are the side plates of the
machine.
As the material is fed into the hopper, the slopes A, A, of same are pressed apart
in proportion to the amount of the feed, and the movement of the said slopes is
immediately transmitted to the doors F, F, by means of the links L, rod K, and
arms J. Should the feed increase, the doors F, F, are opened in the required
proportion, and the said doors are closed to the required degree should the feed
diminish, thereby regulating the passage of the material through the machine in a
regular and efficient manner. The portions H of the doors F, receive a portion of
the weight of the material, thus balancing the said doors and allowing them to work
with ease.

page_text: 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 :-
1. In a machine for drying or conditioning grain, the slopes A, A, and doors F, F,
connected together substantially as described.
2. In a machine for drying and conditioning grain, the combination of the
slopes A, A, the links L, L, the rod K, the arms J, J, and doors F, F, substantially
as described and for the purposes set forth.
3. The general arrangement, construction, and combination of the various parts,
forming our invention for improvements in or connected with machinery for drying
or conditioning grain, substantially as set forth.
