Wo, JOHN ROBERT JEFFERIES Engineer & Ironfounder, Orwell Works, Ipswich
& JAMES KING Draughtsman, Orwell Works, Ipswich do hereby declare the nature of
this invention to be as follows:-
In thrashing machines fitted with an ordinary thrashing drum, we adapt an inclined
stepped straw shaker, which is formed as a part of and in one with the upper jog shoe,
to receive the straw &c. from the thrashing drum; and in combination therewith we
adapt a riddle to receive the straw &c. from the upper jog shoc, which riddle is carried
by and moves together with the lower jog shoe. We also direct a blast to the under-
side of this riddle, when required, for the purpose of slightly lifting the straw as it
passes over the riddle and out of the machine.
When it is required that the straw may be cut and bruised in these machines, we
employ a stepped straw shaker constructed as above described as part of the upper
jog shoe, and in combination therewith we apply chopping and bruising cylinders (one
or two) to receive the straw from the upper jog shoe, and a riddle formed as part of
the lower jog shoe to receive the cut and bruised straw from the cylinder or cylinders,
and to which riddle we apply a blast to the underside when required. In this com-
bination we sometimes apply a grated bottom or concave to the chopping and bruising
cylinder or cylinders, in which case what passes through the concaves is conducted to
the lower jog shoe. We arrange this combination so that the chopping and bruising
cylinders may be put out of action, when the straw is not to be cut and bruised, but
merely thrashed as usual.
In thrashing machines which are not fitted with the ordinary thrashing drum, we
arrange a chopping cylinder to receive the unthrashed corn and deliver on to a stepped
shaker and upper jog shoe such as before described, from which the straw passes into
the bruising cylinder, and thence on to the riddle which is part of the lower jog shoe,
having a blast directed below it, when required.
In this case also the bruising cylinder is sometimes fitted with a grating or concave
below it, and what passes through the same is directed to the lower jog shoe. By

page_text: placing the chopping cylinder and bruising cylinder in the positions above described
no countershaft is required but motion can be given direct from one to the other by a
long driving belt.
In this and in the preceding combination we sometimes apply a jointed check or
curtain falling on to the riddle which riddle is carried by and moves together with
the lower jog shoe for the purpose of preventing grain being thrown out by the
cylinders. We sometimes prefer to make the curtain in flexible material.

We, JOHN ROBERT JEFFERIES, Engineer & Ironfounder, Orwell Works, Ipswich,
and JAMES KING, Draughtsman, Orwell Works, Ipswich, 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 :-
In thrashing machines fitted with an ordinary thrashing drum, we adapt an inclined
stepped straw shaker, which is formed as a part of and in one with the upper jog shoe,
to receive the straw &c. from the thrashing drum and in combination therewith we
adapt a riddle to receive the straw &c. from the upper jog shoe which riddle is carried
by and moves together with the lower jog shoe. We also direct a blast to the under-
side of this riddle, when required, for the purpose of slightly lifting the straw as it
passes over the riddle and out of the machine.
When it is required that the straw may be cut and bruised in these machines, we
employ a stepped straw shaker constructed as above described as part of the upper
jog shoe, and in combination therewith we apply chopping and bruising cylinders (one
or two) to receive the straw from the upper jog shoc, and a riddle formed as part of
the lower jog shoc to receive the cut and bruised straw from the cylinder or cylinders,
and to which riddle we apply a blast to the underside when required. In this com-
bination we sometimes apply a grated bottom or concave to the chopping and bruising
cylinder or cylinders, in which case what passes through the concaves is conducted to
the lower jog shoe. We arrange this combination so that the chopping and bruising
cylinders may be put out of action, when the straw is not to be cut and bruised, but
merely thrashed as usual.
In thrashing machines which are not fitted with the ordinary thrashing drum, we
arrange a chopping cylinder to receive the unthrashed corn and deliver on to a stepped

page_text: shaker and upper jog shoe such as before described from which the straw passes into
the bruising cylinder, and thence on to the riddle which is part of the lower jog shoe,
having a blast directed below it, when required.
In this case also the bruising cylinder is sometimes fitted with a grating or concave
below it, and what passes through the same is directed to the lower jog shoe. By
placing the chopping cylinder and bruising cylinder in the positions above described
no countershaft is required but motion can be given direct from one to the other by a
long driving belt.
In this and in the preceding combination we sometimes apply a jointed check or
.curtain falling on to the riddle which riddle is carried by and moves together with the
lower jog shoo for the purpose of preventing grain being thrown out by the cylinders.
We sometimes prefer to make the curtain in flexible material.
In the drawings hereunto annexed we have shown thrashing machines constructed
as above described.
Figure 1 is a plan, Figure 2 a side elevation partly in section and Figure 3 an end
view also in section of a machine in which a stepped straw shaker forming part of
the upper jog shoe is used to convey the straw away from an ordinary thrashing
drum and deliver it on to a riddle which is carried by and moves with the lower jog
shoe.
A is the thrashing drum-B the inclined stepped straw shaker which is composed
of a series of parallel bars of wood fixed stepwise or of sheet metal bent stepwise
which may if desired be perforated in places to allow the corn to fall through on to
the tray underneath-the inclined step shaker is sometimes fitted with small spikes bb
to assist the travel of the straw-B' is a perforated sieve over which the straw travels
the corn falling through on to the tray C-these with the step shaker B form the
upper jog shoc. D is the riddle fixed to the lower jog shoe E to receive the straw as
it passes off from the end of the shaker B. The corn falling through riddle D is
conveyed back to the ordinary dressing screen as shown. Fis fan by which an air
blast can be directed to the underside of this riddle. The jog shoes C and E have a
reciprocating to and fro motion given to them by connecting rods passing to cranks
on a crank shaft in the ordinary way-these cranks and connecting rods are not shown
in the drawing.
Figure 4 is a plan. Figure 5 a side elevation mostly in section and Figure 6 an
end view also in section of a thrashing machine in which the stepped straw shaker
which forms part of the upper jog shoc conveys the straw to chopping and bruising
cylinders from which it is passed onwards to the riddle carried by the lower jog shoe.
A is the thrashing drumm of any ordinary construction. B the stepped straw shaker.
the tray under shaker and forming with it the upper jog shoe. G is a chopping
cylinder and H a bruising cylinder working with concaves G H which may be of
ordinary construction but which we prefer to form of gratings to afford an outlet for
any grain which may remain in the straw.
Hitherto chopping and bruising cylinders used in thrashing machines for chopping
and bruising straw brought to them by straw shakers from a thrashing machine have
not been formed with grated or openwork concaves because in machines of this kind
in which chopping and bruising cylinders have been used no facility was afforded for
conveying corn escaping through such concave back to the dressing shoe. Consequently
they were not used but in this case would be conveyed back by E to the dressing
screen of the lower shoe.
D is the riddle on to which the chopped and bruised straw passes from the bruising
cylinder F. E is the lower jog shoe which carries it and F a fan for delivering a
current of air to the underside of the riddle D. I is a casing into which the chopped
and bruised straw coming from the bruising cylinder rises and then drops on to the
riddle D. J is a curtain either jointed to the top of the mouth of the casing I or
formed of flexible fabric to prevent straw or grain being blown out without first
falling on to the riddle.
In the drawing we have shown two cylinders G H one a chopping and the other a

page_text: bruising cylinder but each cylinder may as is well understood be formed both to chop
and bruise the straw or a single cylinder for both chopping and bruising might be
used. When it is desired that the machine should be used for threshing out grain
without chopping and bruising the straw, then we construct the machine in such
manner that the casing above the cylinders G H and the casing I can readily be removed
and a prolongation added to the shaker B as shewn by dotted lines in Figure 5 so
that the straw passing off from its end may drop directly on to the riddle D.
Figure 7 is a plan. Figure 8 a side elevation mostly in section and Figure 9 an
end view also in section of a machine in which the unthrashed corn is first acted upon
by a chopping cylinder then conveyed away by the stepped shaker of the upper jog
shoe to a bruising cylinder and from this cylinder passes on to a riddle fixed to the
lower jog shoe.
G is the chopping cylinder, B the stepped shaker, the tray under shaker and
forming with it the upper jog shoe. Hthe bruising cylinder and D the riddle fixed
to the lower jog shoe E. F is the fan for delivering a current of air to the underside
of the riddle B. I is the casing into which the chopped and bruised straw rises
from the cylinder Hand J is the curtain at the mouth of this casing either turning
on hinges at the top or made flexible as desired. The machine might be constructed
without the bruising cylinder and so that the chopped straw is delivered directly on
to the riddle D or may be constructed as described with reference to Figures 4, 5 and 6
in such manner that the straw may be either bruised or not as desired.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In a thrashing machine the combination of the stepped straw shaker which is in
one with the upper jog shoe and a riddle which is carried by and moves together with
the lower jog shoe to receive the straw when it passes off from the end of the shaker
substantially as described.
2. In a thrashing machine the combination of the stepped straw shaker which is in
one with the upper jog shoe-the riddle carried by the lower jog shoe and the fan
delivering a current of air to the underside of this riddle substantially as described.
3. In a thrashing machine the combination of the thrashing drum, the stepped
straw shaker which is in one with the upper jog shoe, the chopping and bruising
cylinder or cylinders to which the straw is delivered by the shaker, and the riddle
which is carried by and moves with the lower jog shoe substantially as described.
4. In a thrashing machine the combination of the thrashing drum, the stepped
straw shaker which is in one with the upper jog shoe, the chopping and bruising
cylinder or cylinders, the riddle which is carried by and moves with the lower jog
shoe and the fan delivering a current of air to the underside of the riddle substantially
as described.
5. The arrangement of the machines substantially in the manner hereinbefore
described to permit of the straw being either subjected to the action of the chopping
and bruising cylinders or passed from the shaker direct to the riddle carried by the
lower jog slioe.
6. In a thrashing machine the combination of the chopping cylinder, the stepped
straw shaker fitted to the upper jog shoe, and the riddle carried by and moving with
the lower jog shoe.
7. In a thrashing machine the combination of the chopping cylinder, the stepped
straw shaker fitted to the upper jog shoe, and the riddle carried by and moving with
the lower jog shoe, and the fan delivering a current of air to the underside of the 5
riddle.
8. In a thrashing machine the combination of the chopping cylinder, the stepped
straw shaker fixed to the upper jog shoe, the bruising cylinder and the riddle carried
by and moving with the lower jog shoc substantially as described.
9. In a thrashing machine the combination of the chopping cylinder, the stepped

page_text: straw shaker fixed to the upper jog shoe the bruising cylinder and the riddle carried
by and moving with the lower jog shoc and the fan delivering a current of air to the
underside of the riddle substantially as described.
10. In thrashing machines in which thrashed straw is conveyed to chopping and
bruising cylinders forming the concaves of such cylinders of openwork gratings to
allow of grain dropping through and conducting such grain on to the dressing screen
of the lower shoe substantially as described.
11. In thrashing machines in which thrashed straw is conveyed to chopping and
bruising cylinders and in which the straw passes from such cylinders on to a riddle
carried by the lower shoe as hercin described the combination of the jointed check or
curtain with tho riddle to prevent corn escaping with the chopped straw.
