Complete Specification Accepted, 14th Dec., 1888
I JAMES MARSHALL of the firm of Marshall Sons & Co. Limited of Britannia Iron
Works, Gainsborough in the County of Lincoln Engineers do hereby declare the
nature of this Invention to be as follows:-
The object of this Invention is to provide means for catching any grain which may
pass over the ends of the shakers of thrashing machines and for returning it again
into the machine.
According to this Invention I provide a trough or box the upper part of which can
be lathed in the manner of an ordinary straw crate. In this box or trough belts with
cross laths travel over rollers the said laths travelling, upwards in contact with the
bottom of the box or trough. The said box or trough is situated at the end of the
shakers in such a position that when straw falls from the shakers any grain in it drops
into the box or trough and is carried up by the travelling belts and laths and is
delivered back into the machine preferably into the top of the upper dressing shoe.
The rollers carrying the belts can conveniently derive their motion from one of the
shaker crank shafts. In order that the device may be readily put in position either
for use or for travelling it may hang on a centre (which may be the spindle of the
upper belt carrying roller) and be suspended by carrying rods provided with hooks
and eyes or other means of attachment so that the box or trough can be supported
thereby in its lowered position or in its raised position and any parts which would
in the latter position foul any part of the machine can be hinged and be folded
back.

page_text: I, JAMES MARSHALL of the firm of Marshall Sons and Company Limited of
Brittania Iron Works, Gainsborough in the County of Lincoln 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 :-
The object of this Invention is to provide means for catching any grain which may
pass over the ends of the shakers of thrashing machines and for returning it again into
the machine.
The accompanying drawings will serve to clearly illustrate my invention Figures 1
and 2 being respectively a side view partly in section and a plan of so much of a
machine as is necessary to show the application of my invention thereto. Figures 3
and 4 are similar views of a modification as hereinafter described.
I provide a trough or box X the upper part (at a) of which can be lathed in the
manner of an ordinary straw crate. In this box or trough belts C with cross laths D
travel over rollers A and B the said laths D travelling upwards in contact with the
bottom of the box or trough X. The said box or trough X is situated at the end of
the shakers in such a position as shown that when straw falls from the shakers it
drops on to the laths at a and any grain in it drops into the box or trough X and is
carried up by the travelling laths B on the belts C and is delivered back into the
machine preferably into the top of the upper dressing shoe E-The rollers A and B
carrying the belts C can conveniently derive their motion from one of the shaker
crank shafts as shown at F. In order that the device may be readily put in position
either for use or for travelling it may hang on a centre (which may be the spindle
of the upper belt carrying roller as at g) and be suspended by carrying rods h h
provided with hooks and eyes or other means of attachment so that the box or
trough X can be supported thereby in its lowered position as shown in full lines or
in its raised position as shown in dotted lines and any parts which would in the latter
position foul any part of the machine can be hinged and be folded back-A con-
venient arrangement consists in making the rods in two lengths so that when the
box X is to be raised they are unhooked and the hook of the upper portion of the
rod is engaged with the ring J the hook of the lower part of the rod / being
engaged with the eye i when the apparatus is lowered for use.
In cases where straw elevators are employed we prefer the modification shown in
figures 3 and 4 the trough X being without the lathed cover and the trough bottom
under the upper portion of the belts consists of laths as at ². The grain falling
through the laths on to the trough bottom N is then taken up by the cross bars D
and delivered on to the upper dressing shoe E as before explained. The springs
marked Z we use as an agitator and belt tightener as the bars D pass over them they
are pressed down and as soon as the bars are clear of them they spring up and shake
the straw in its passage along the elevator.

page_text: Figures 5 and 6 are similar views of a modification wherein I use a series of
pegs P (preferably of iron) affixed to the bars D carried by the belts C and
projecting through the lather cover a the grain, chaff, and the like falling through
the laths on to the trough bottom being taken up by the pegs P and delivered on to
the upper dressing shoe E.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
First. In thrashing machines a box or trough for catching any grain which may
pass over the ends of the shakers and provided with means for returning the said
grain to the machine substantially as herein before described.
Second. The attachment for thrashing machines for catching any grain which may
pass over the ends of the shakers and returning the said grain again to the machine
the said attachment being provided with means for readily securing it in its raised or
lowered positions substantially as hereinbefore described and illustrated in the
accompanying drawings.
Third. The arrangement of grain saver and means for operating it as herein before
described and shown in Figures 1 and 2 of the accompanying drawings and also the
modification herein before described and shown in Figures 3 and 4 and 5 and 6 of the
accompanying drawings and as attached to thrashing machines alone or in conjunction
with straw elevators or other appliances of this nature.
Dated this 13th day of November 1888.
