Improvements in or connected with Steve Cut Offs for Grain
Cleaners and analogous purposes.
A communication by DAVID J. DAVIDSON, ABRAHAM S. MARTIN, and

and State of Michigan, United States of America.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object a sieve cut off for grain cleaners and analogous
purposes and it consists of the construction, combination and arrangement of devices
and appliances hereinafter specified.
In carrying out the invention, a screen frame is provided with any suitable
screen. Beneath the screen and spaced therefrom, à series of spouts or grain
conductors is provided, separated one from another and discharging into a cut off
box or trough under their lower ends. These spouts are preferably located on an
angle. A flooring may be located intermediate said spouts at their upper adjacent
edges.
It must be understood that the screen is to be agitated by any suitable
mechanism. The box may or may not be agitated. It may remain stationary or
it may be connected with the sieve frame by supporting arms, to be simultaneously
agitated therewith, or it may be agitated independently of the sieve as may be
desired.
The spouts, and intermediate flooring if employed may be of any desired form or
shape. It will be seen that when the screen is agitated its vibrations will cause the
grains, or other materials passed therethrough, to be discharged into the box.
This box is constructed with a series of orifices, preferably in its base, said orifices
being controlled by suitable valves or slides of any suitable construction. By this
construction it will be seen that when the grain or other material is discharged into
the box it may be cut off at any desired point by opening the corresponding valve
or slide. It will be seen that by means of the screen and the cut off of the
separating box, any desired separation of the grain can readily be made.
The cut-off or separating box may also, within the scope of this invention be
attached to any screen or separating machine for separating all kinds of grains,
seeds, flour and other articles where separating and grading are required.
So also the cut-off or separating box may be attached at any side of the screen
as may be desired. The box may be made of any length or width as may be
desired and may be provided with any required number of discharge openings and
cut-off valves or slides.

A communication by DAVID J. DAVIDSON, ABRAHAM S. MARTIN, and

and State of Michigan, United States of America.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil 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:-
This invention has for its object a sieve cut off for grain cleaners and analogous
purposes, and it consists of the construction, combination and arrangement of
devices and appliances hereinafter specified and claimed and illustrated in the
accompanying drawings, in which,
Figure 1 is a view in perspective illustrating the invention;
Figure 2 is a plan view of the same;
Figure 3 is a vertical cross section on the line 3-3 of Figure 2.
The invention is carried out as follows-
A indicates a screen frame provided with any suitable screen A. Beneath the
screen and spaced therefrom, a series of spouts or grain conductors a is provided,
separated one from another and discharging into a cut off box or trough B under
their lower ends. These spouts a are preferably located on an angle, as shown
more particularly in Figure 3. A flooring A may be located intermediate said
spouts a at their upper adjacent edges as shown.
It must be understood that the screen is to be agitated by any suitable
mechanism. The agitating mechanism not forming a feature of the present
invention is not shown herewith. The box B may or may not be agitated. It
may remain stationary or it may be connected with the sieve frame by supporting
arms as indicated by dotted lines in Figure 1 to be simultaneously agitated
therewith, or it may be agitated independently of the sieve as may be desired.
The spouts a and intermediate flooring if employed may be of any desired form or
shape. It will be seen that when the screen is agitated, its vibrations will cause
the grains, or other materials passed therethrough, to be discharged into the box B.
This box is constructed with a series of orifices 6, preferably in its base, said
orifices being controlled by suitable valves or slides of any suitable construction,
slides being shown in the drawings at . By this construction it will be seen that
when the grain or other material is discharged into the box B it may be cut off at
any desired point by opening the corresponding valve or slide. It will be seen
that by means of the screen and the cut off of the separating box, any desired
separation of the grain can readily be made.
The cut-off or separating box B may also within the scope of this invention be
attached to any screen or separating machine for separating all kinds of grains,
seeds, flour and other articles where separating and grading are required.
So also the cut-off or separating box may be attached at any side of the screen
as may be desired. The box may be made of any length or width as may be
desired and may be provided with any required number of discharge openings and
cut-off valves or slides.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is-
1. The combination with an agitable sieve, of a series of spouts or conveyors, a
cut off box into which said spouts or conveyors discharge, said box constructed with
a series of discharge orifices and provided with valves or slides to control said
orifices, substantially as set forth.
2. The combination with an agitable screen of a series of spouts or conveyors
located there beneath and agitable therewith, and a cut-off box into which said
spouts discharge, said box constructed with a series of discharge orifices and
provided with valves or slides to control said orifices, substantially as set forth.
3. The combination with an agitable sieve, of a series of spouts located there
beneath, an agitable cut-off box into which said spouts discharge, said box con-
structed with discharge openings and provided with valves or slides to control said
openings substantially as set forth.
4. The combination with a sieve or screen of a cut off box into which the
products passed through the screen are discharged, said box constructed with a
series of discharge openings and provided with a corresponding series of valves or
slides to control said openings, substantially as set forth.
5. The cut-off box herein described constructed with a series of discharge
orifices and provided with a corresponding series of valves or slides to control said
orifices, substantially as set forth.
6. The combination with a sieve or screen of a series of spouts or conveyors
located there beneath and agitable therewith, substantially as described.
