PROVISIONAL SPECIFICATION.
Improvements in the Elevating Apparatus of Portable Combined
Chaff Cutters.
I ROBERT MAYNARD, Whittlesford Works near Cambridge Engineer, Iron
and Brass Founder do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in the elevating apparatus of a combined
chaff cutter and has for its object to prevent the lumping of the chaff thus ensuring
the continuous and easy working of the machine.
As heretofore constructed such elevating apparatus has consisted of two endless
belts or chains furnished with cross bars or sweepers running over pullies at top
and bottom and working in a trough. As the chaff is cut it falls on to a riddle
which passes it through on to a false bottom whence it falls on to the lower end of
the elevator, and is then lifted by the action of the endless belts and sweepers and
fed into bags or other suitable receptacles. The disadvantage of this construction
of elevator is that the chaff is not cleared out sufficiently fast from the false bottom
but is allowed to accumulate there whence it falls into the bottom of the elevator in
lumps through which the endless belts and sweepers cannot cut their way and a
stoppage ensues.
To obviate these defects in .constructing the elevating apparatus of a combined
chaff cutter I place the lower end or entrance for the chaff on the same level as the
outlet of the false bottom while instead of the sweepers terminating at the bottom
of the trough as heretofore they are continued into such false bottom between it
and the riddle and as they work over the pullies or rollers or their equivalents they
by their action rake or sweep out the chaff thus preventing it from accumulating
and lumping. By this means the sweepers are kept running continuously and so
carry up the chaff and feed it into the bags or other receptacles provided
therefor.

Improvements in the Elevating Apparatus of Portable Combined
Chaff Cutters.
I, ROBERT MAYNARD, Whittlesford Works, near Cambridge, Engineer, Iron
and Brass Founder, 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 relates to improvements in the elevating apparatus of portable
combined chaff cutters, and has for its object to prevent the lumping of the chaff
thus ensuring the continuous and easy working of the machine.
As heretofore constructed such elevating apparatus has consisted of two endless
belts or chains, furnished with cross bars or sweepers running over pullies at top
and bottom, and working in a trough. As the chaff is cut it falls on to a riddle
which passes it through on to a false bottom, whence it falls on to the lower end of
the elevator, and is then lifted by the action of the endless belts and sweepers, and
fed into bags or other suitable receptacles. The disadvantage of this construction
of elevator is that the chaff is not cleared out sufficiently fast from the false bottom
.

in lumps through which the endless belts and sweepers cannot cut their way, and a
stoppage ensues.
To obviate these defects, in constructing the elevating apparatus of a combined
chaff cutter, I place the lower end or entrance for the chaff on the same level as
the outlet of the false bottom while instead of the sweepers terminating at the
bottom of the trough as heretofore, they are continued into such false bottom
between it and the riddle, a hole being cut in the riddle to allow the sweepers to
pass through, and which hole is boxed round to prevent the rough chaff falling
through. As the sweepers work over the pullies or rollers, or their equivalents,
they by their action rake or sweep out the chaff, thus preventing it from accumu-
lating and lumping. By this means the sweepers are kept running continuously,
and so carry up the chaff and feed it into the bags or other receptacles provided
therefor.
The accompanying drawing shews a view in side elevation of my improved
elevating apparatus as it appears when in use with a portable combined chaff cutter.
A are the knives of the machine cutting against the mouth piece B. As the chaff
is cut it falls on to the riddle C through which it passes and falls on to the false
bottom D. Thence it is swept out by the sweepers E and is by them carried up
the elevator F. The chaff enters the elevator at the point G while the sweepers
are guided into their proper course by the pullies H over which they work.
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.
In a portable combined chaff cutter an elevating apparatus having the entrance
for the chaff placed on the same level as the outlet of the false bottom, and the
sweepers continued into such false bottom between it and the riddle so that as they
work over the pullies or rollers they sweep out the chaff from the false bottom and
thus prevent it accumulating and lumping therein, all substantially as hereinbefore
described.
