COMPLETE SPECIFICATION.
An Improvement in the Method of Beating, Caving, Sifting Cut Chaff
and the like, and Elevating the Cavings into the Feed Box to be
applied to Chaff Cutters.
I, SAMUEL TREWIN of No. 30 Queens Road, Watford, Herts, Corn and Coal
Merchant 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:
-
My invention consists of placing a reel or fan under the mouth of the cutter,
with a caseing underneath and at the back to guide the cut material into the reel
or fan which disseminates the chaff and forces it against a current of air produced
as shown in l'atent No. 8657, 1896. The cut material is thrown into a movable
platform which obtains its action from the riddle, being connected by a rod; the
platform feeds the chaff into the caver, the cavings are discharged by a side shute
into an elevator which conveys it again into the feed box; the chaff which passes
through the caver is carried by a shute or table to the extreme end of the sifter
thereby securing the maximum sifting surface.
And that my invention may be rightly understood I will describe the same by.
the accompanying drawings reference being made to the figures and letters
thereon.
Fig. 2 is a side elevation of the reel or fan, K, which is built into and extends
the width of the box described in my Patent No. 8657, 1896, the casing M. M at
the back and underneath the reel also extends the full width of the box, at N. a
movable platform hinged at O. and worked by a connecting rod P attached to
the riddle gives the required motion for feeding the cut material into the caver S.
Underneath the caver is placed a table which receives the chaff as it drops from
the caver and delivers it at t into sifter h. The cavings are disposed of by a spout
at the end of and by the side of the riddle at W. into an elevator which is encased
and driven by extending the crank shaft i Fig. 3.
Fig. 4 gives a side elevation of the elevator which carries the cavings back into
the feed box, it is supported by wrought iron brakets with an angle and slot as
shown at W. Fig. 4 and bolted to the side of the feed box; a bolt is fitted into the
slot with reel to carry the sides of the elevator and also acts as a guide and
tension to the elevator as it returns.
Fig. 5 shows the elevator as it passes up through the frame of the machine to
the feed box.
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 an improvement in the method of, beating, caving, sifting cut chaff and
the like, and elevating the cavings into the feed box to be applied to chaff cutters.
Firstly. By placing a rotary reel or fan as described at K Fig. 2 with
casing M. M. extending the width of the box described in my Patent No. 8657,

page_text: 1896, anu shown in the accompanying drawings at b. b. Fig. 3 the friction is
reduced to a minimum and the chaff or the like thoroughly disseminated.
Secondly. By carrying the chaff at the extreme end of the caver by a moving
platform O. Fig. 2 and by constructing a shute or table under the cave to receive
the chaff as it passes through the cave and delivers the same to the end of the
sifter described at t, Fig. 2. thereby securing the maximum riddling and sifting
surfaces.
Thirdly. By constructing an elevator as shown at Fig. 4 the cavings may be
returned to the feed box as they are produced and delivered by the caver, thus
saving the labour of attending and handling the same.
