PROVISIONAL SPECIFICATION.
Improvements in the Bagging Apparatus of Portable Combined
Chaff Cutting Engines.
I ROBERT MAYNARD of Whittlesford Works near Cambridge Engineer do
hereby declare the nature of this invention to be as follows:-
· This invention has for its object to prevent the choking in a chaff cutting engine
that now so frequently occurs owing to the lumping of long damp cut chaff."
This I effect by dispensing with the ordinary hopper and substituting therefor an
extension formed on the lower end of the bagging apparatus of a chaff cutting
engine which extension passes under the machine and catches the chaff as it falls
from the riddle. I then attach such bagging apparatus to the frame of the machine
by suitable lever arms which allow the apparatus to work freely up and down
while they prevent the before mentioned extension coming in contact either with
the ground or the bottom of the riddle..
By this improved construction of bagging apparatus the chaff falls direct on to
the endless sweepers working inside such apparatus and is carried on the top of
such sweepers, instead of the sweepers having to dig out the chaff from a hopper
and sweep it up under them as formerly, and consequently the long damp chaff
which is now found so troublesome, on account of its propensity to lump and choke
the machine can thus be easily and readily elevated.

COMPLETE SPECIFICATION.
Improvements in the Bagging Apparatus of Portable Combined
Chaff Cutting Engines.
I, ROBERT MAYNARD of Whittlesford Works near Cambridge, Engineer, 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 has for its object to prevent the choking that now so frequently
occurs in the bagging apparatus or elevator of a chaff cutting engine owing to the
lumping of long damp cut chaff.
This I effect by dispensing with the ordinary hopper now generally employed to
catch the chaff as it falls from the riddle, and substituting therefor an extension
formed on the lower end of the bagging apparatus, which extension passes under
the machine and catches the chaff as it falls from the riddle. I attach such bagging
apparatus to the frame of the machine by suitable lever arms which allow the
apparatus to work freely up and down while they prevent the before mentioned
extension coming in contact either with the ground or the bottom of the riddle.
By this improved construction of bagging apparatus the chaff falls direct on to the
endless sweepers working inside such bagging apparatus, and is carried on the
top of such sweepers instead of the sweepers having to dig out the chaff from a
hopper and sweep it up under them as formerly, and consequently the long damp
chatt which is now found so troublesome on account of its propensity to lump and
choke the machine, can thus be easily and readily elevated.
The accompanying drawing shews a portable combined chaff cutter in front
elevation fitted with my improved bagging apparatus, which is seen therein in side

page_text: elevation. a is the knife wheelttle-knizes on--which cut against the mouth 6. in the
ordinary way. As the chaff is cut it falls on to the riddle c. which sifts out the
imperfectly cut feed. The chaff after being so sifted falls into the false bottom or
conductor d which delivers the chaff at the outlet 4. on, to the extension e¹ and
sweepers which latter slide up the board or false bottom g and are driven by
a belt or otherwise in the direction of the arrows and so elevate and deposit the
chaff in bags at h.
The bagging apparatus or elevator is fitted with lever arms or rods ; which are
pivotted. to the frame of the machine and to the bagging apparatus, and are
preferably of unequal length, so that when such, bagging apparatus or elevator is
raised or lowered it is kept in, such a position that the extension formed thereon
neither comes in contact with the bottom of the riddle or with the ground. The
. position which the bagging apparatus of elevator assumes when raised is.indicated
in dotted outlines in the accompanying drawing.
"Having now particularly described and ascertained the nature, of the said
invention and in what manner the same is to be performed, I declare that what
I claim is,
Firstly. In combination with a portable combined chaff cutting engine a bagging
apparatus or elevator provided at its lower. end with a suitable extension on to
which the chaff falls as it is delivered from the riddle all substantially as herein-
before described and shewn.
Secondly. In a portable combined chaff cutting engine regulating the position of
the bagging apparatus or elevator by suitable lever arms or rods all substantially
as hereinbefore described and shewn.
Thirdly. In a portable combined chaff cutting engine the improved construction
and arrangement of bagging apparatus all substantially as hereinbefore described
and shewn.
