Republic, Engineer.]
Improvements in Thrashing Machines.
We, EDWARD FOSTER SANDON, and DINELY FOWLER TONGE, both of the City of
Lincoln, Engineers, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to render ordinary thrashing machines more suitablo
for thrashing lucern or alfalfa, linseed and other small seeds.
For this purpose, a six beater drum is preferably employed and the thrashing
screen and concave are, at their back, preferably covered or stopped with sheet iron.
Under the caving riddle, and in the same shoe or hopper, is arranged an extra
riddle for the purpose of arresting the unthrashed pods or heads which pass through
the caving riddle; the seeds pass through the said extra riddle to the wind riddle and
any unthrashed pods or heads that may pass through with the seeds will be arrested
by the wind riddle and will be conducted to an elevator as hereinafter stated.
A spout or shoot is provided at the side of the shoe or hopper to carry away the
unthrashed pods or beads arrested by the extra riddle and another spout or shoot is
provided at or near the upper side of the wind riddle to carry away any unthrashed
pods or heads arrested by the last mentioned riddle. Both of the said spouts or shoots
lead into and conduct the unthrashed pods or heads into a special elevator preferably
of the kind known as a blast or chuck elevator. This elevator, which is furnished
with suitable change plates, so that it may itself assist in acting upon and breaking
the said pods or heads, collects everything arrested by the extra riddle and wind
riddle and elevates it to the top of the thrashing machine where it may be continuously
delivered into the drum for re-thrashing or allowed to accumulate in some convenient
place to be fed by hand into the drum at intervals.

COMPLETE SPECIFICATION.
Improvements in Thrashing Machines.
We, EDWARD FOSTER SANDON and DINELY FOWLER TONGE, both of the City of
Lincoln, Engineers, 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 render ordinary thrashing machines more suitable
for thrashing lucern or alfalfa, linseed and other small seeds.
For this purpose, a six beater drum is preferably employed and the thrashing screen
and concave are, at their back, preferably covered or stopped with sheet iron.
Under the caving riddle, and in the same shoe or hopper, is arranged an extra
riddle, for the purpose of arresting the unthrashed pods or heads which pass through
the caving riddle, the seeds pass through the said extra riddle to the wind riddle, and
any further unthrashed pods or heads that may pass through with the seeds will be
arrested by the wind riddle.
A spout or shoot is provided at the side of the shoe or hopper to carry away the

page_text: unthrashed pods or heads arrested by the extra riddle and another spout or shoot is
provided at or near the upper side of the wind riddle to carry away any unthrashed
pods or heads arrested by the last mentioned riddle. Both of the said spouts or shoots
lead into and conduct the unthrashed pods, or heads into an elevator preferably of the
kind known as a blast or chuck elevator. This elevator, which is furnished with
suitable change plates, so that it may itself assist in acting upon and breaking the said
pods or heads. collects everything arrested by the extra riddle and wind riddle and
elevates it to the top of the thrashing machine, where it may be continuously delivered
into the drum for rethrashing or be conveyed to the riddling apparatus.
And in order that the said invention may be more clearly understood and readily
carried into effect, we will proceed, aided by the accompanying drawings, more fully
to describe the same.

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. The general arrangement of parts constituting a thrashing machine, substantially
as herein shown and described.
2. In a thrashing machine an extra riddle interposed between the caving riddle and
the wind riddle, substantially as herein shown and described.
3. In a thrashing machine, the combination of a caving riddle, a wind riddle, an
extra riddle interposed between the two, a hopper and suitable shoots to convey the
intercepted matter to an elevator, substantially as herein shown and described.
4. In a thrashing machine the combination of a caving riddle, a wind riddle, an
extra riddle interposed between the two, a hopper, suitable shoots to convoy the
intercepted matter to an elevator and an elevator fitted with suitable change plates,
all in manner substantially as herein shown and described and for the purpose
stated.
