IMPROVEMENTS IN THRASHING MACHINES
Year: 1885

page_text: و"
I EDWIN FODEN of Sandbach in the County of Chester Engineer do hereby
declare the nature of my invention for “IMPROVEMENTS IN THRASHING MACHINES
to be as follows:-
My invention relates first to improvements in the dressing or finishing apparatus
for which Letters Patent No 4604 were granted to me dated 21st day of October
1881, and consists in the following improvements thereon.
1. Instead of putting the air inlets below the branch pipe I (as shown on the
drawings and described in the Specification of the Patent above referred to) I place
the said air inlets just below the delivery mouth of the scourer on one or more
sides, of the vertical pipe D.
2. In place of the light corn pocket or enlargement B¹ at the back of the machine
I provide a light corn pocket on the same side of the machine as the fan, and at
the outside of the drop box a vertical pipe D, and I provide the same with air
inlets to dress the light corn.
3. Instead of having dividing ribs or plates N, on the delivery mouth of the
scourer, I use a curved or flat mouth with the lip turned upwards to prevent the
light corn from being driven down by the force of the delivery from the scourer
and I also arrange this lip (or a hanging door on the other side of the drop box).
that the area of this part of the drop box may be increased or diminished to suit
the quantity of corn passing through the machine.

4. When the machine is required to dress smut wheat or damp corn I remove
the vanes or wings from the inside of the scourer and instead of having the branch,
pipe II place a worm inside the scourer to deliver the corn into the vertical"
pipe D.
The second part of my invention relates to improvements in the construction of
thrashing machines for which Letters Patent No 2985 were granted to me dated
23rd day of June 1882 and consists in substituting for the regulating slide H,
(shown on the drawings and described in the Specification of such Letters Patent)
inside the air passage of the riddle box, a spindle valve inside the said passage,
with a lever attached to the spindle outside the same, so as to be able to regulate
the first air dressing current from the outside whilst the machine is in motion.

I EDWIN FODEN of Sandbach in the County of Chester Engincer do hereby
declare the nature of my invention for "IMPROVEMENTS IN THRASHING MACHINES
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My Invention relates first to improvements in the dressing and finishing apparatus
(applied to thrashing machines) for which Letters Patent N° 4604 were granted to
me dated 21st day of October 1881, and consists in certain improvements thereon
herein after described.
The nature of these improvements and the manner in which the same are to be
performed or carried into practical effect will be readily understood on reference
to the accompanying drawings and the following explanation thereof.
Fig. 1. on the annexed drawing is a longitudinal section and Fig. 2 a trans-
verse section of so much of a thrashing machine as is necessary to illustrate my
invention.
In the first place instead of putting the air inlets below the branch pipe (indicated
by the letter I in the drawings and described in the Specification of the Letters
Patent above referred to) I place the said air inlets at a, a just below the delivery
mouth of the scourer on one or more sides of the vertical pipe (marked D; and
mentioned and referred to in the above named Specification) see Fig. 2 of the
drawings hereto annexed.
Secondly in place of the light corn pocket or enlargement B₁ at the back of the
machine I now provide a light corn pocket b, b on the same side of the machine
as the fan and at the outside of the drop box or vertical pipe D and I provide the
same with air inlets c, c and with outlets d, d for the light corn..
Thirdly-Instead of having dividing ribs or plates (marked N on the drawings
of my previous Patent) on the delivery mouth of the scourer I use a curved or flat
mouth with a sliding plate e, c, to prevent the light corn from being driven down
by the force of the delivery from the scourer, and I also arrange the slide'è, e or
a hanging door f, on the other side of the drop box D, (or both a slide and a door
as shown at Fig. 2) so that the area at this part of the drop box may be increased
or diminished to suit the quantity of corn passing through the machine.
"
Fourthly when the machine is required "smut wheat or damp corn I remove
the vanes or wings A, from the inside of the scourer and instead of having a branch
pipe (marked I on the drawings of my former Patent) I place a worm g, g inside
the scourer to deliver the corn direct into the vertical pipe or drop box D.
In the drawing at Fig. 2 the scourer is shown with the lower half wings or
vanes and the upper half with a worm.
The second part of my invention relates to improvements in the construction of
thrashing machines for which Letters Patent N° 2985 were granted to me dated
23rd day of June 1882 and consists in substituting for the regulating slide (marked H
on the drawings accompanying the Specification of such Letters Patent) inside the
air passage of the riddle box a spindle valve h, h (see Fig. 1.) with a lover i, ¿

page_text: attached to the spindle outside the same so as to be able to regulate the first air
dressing current from the outside whilst the machine is in motion.
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
First. In thrashing machines (of the construction herein before first mentioned)
the use or employment of air inlets just below the delivery mouth of the scourer
on one or both sides of the vertical pipe or drop box
Secondly. The uso in such thrashing machines of a light corn pocket on the
same side of the machine as the fan and on the outside of the vertical pipe or
drop box and provided with air inlets for dressing the light corn.
Thirdly. The use of a curved or flat adjustable slide below the delivery mouth
of the scourer either by itself or in connection with an adjustable hanging door or
flap on the other side of the vertical pipe or drop box.
Fourthly. The use of a worm in place of the vanes or wings on the shaft inside
the scourer when required to dress "smut wheat" or damp corn.
Fifthly. In thrashing machines (of the construction second above mentioned)
the use of a spindle valve inside the air passage of the riddle box with a lever
attached to the spindle outside the same so as to be able to regulate the first air
dressing current from the outside whilst the machine is in motion.
