PROVISIONAL SPECIFICATION.
An Improved Screening or Separating Machine for Potatoes,
Cinders, and the like.
I GEORGE HUNTER TYSON Farmer Billincoat Dalton in Farness Lancashire
do hereby declare the nature of this invention to be as follows :—
An inclined cylinder on which are placed moveable riddles or screens of different
sizes of mesh made of wire or iron, which are fixed outside or inside of cylinder by
bolts or screws. The cylinder has a centre shaft working in bearings at each end
on an inclined frame of wood or iron. The cylinder being turned by hand or other
power. The dirt, small potatoes &c. drop under cylinder into spouts or divisions,
the large potatoes &c. come out at the mouth of cylinder at the opposite end of the
separater from which it is turned. The potatoes &c. are fed into the cylinder from
a hopper with or without plates worked inside hopper by crank or eccentric from
centre shaft, & spiral spring or other device inside hopper. The separating cylinder
may also be fed from hopper by moveable mouthpiece worked by crank or eccentric
on centre shaft, or lever worked by hand or power. The separater may be used
for separating green & dried fruits, nuts, cockles ground bones, cinders, coal iron
ore & other purposes, by placing stronger riddles or screens out or inside
cylinder.

COMPLETE SPECIFICATION.
An Improved Screening or Separating Machine for Potatoes,
Cinders, and the like.
GEORGE HUNTER TYSON Farmer Billincoat Dalton-in-Furness 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 potatoes, cinders and the like are placed into the hopper A and pass over
and between the moveable plates B worked by an eccentric C they then fall into
the mouth piece D which is worked by lever E and then pass into the inclined
cylinder F. F. F. on which are fixed (either inside or outside) moveable riddles G 1.
G2. G 3. The potatoes and the like drop from the mouthpiece D into riddle G 1.
through which the dirt falls and move forward as the cylinder revolves into
riddle G. 2. through which the small potatoes fall into a spout thence on into
riddle G. 3. through which the seed potatoes fall into another spout and the large
or marketable potatoes pass, forward and out at the end of the inclined cylinder into
spout H where a bag can be fixed.
The plates B 1. are fixed by hinges to the sides of the inside of hopper A. and
rest with a nib or longer bar (of which the plates shewn in Fig. 1 and Fig. 2. are
composed) onto the bottom corners of plate B. 2. which is also fixed by hinges to
end of inside of hopper A. as shewn in Fig. 2. and has a nib or longer bar in centre
of plate B. 2. and resting on eccentric C. so that as the centre shaft is turned all
the three plates B 1. B 1. and B. 2. rise and fall at each half turn of the cylinder
when in motion thereby causing a shaking motion which prevents potatoes and the
like from lodging or choking as they fall onto mouthpiece D. when fed into
banner A

page_text: The moveable mouthpiece D is also composed of thin iron bars same as the
plates shewn in Fig. 1. and Fig. 2. which prevent so much soil and dirt being fed
into cylinder F. F. F.
The flanges K. are pieces of iron set on edge and fixed (by bolts or screws) in a
slanting direction longways inside of cylinder (as shewn in drawing Fig. 1) onto a
broad hoop of sheet iron which is part of cylinder so that as the cylinder F. F. F.,
revolves the flanges clear away the potatoes from the lip of the mouthpiece D. and
they pass onto the first riddle G. 1. As the inclined cylinder revolves the potatoes
work themselves forward and separate as they pass over the other 2 riddles G. 2.
and G. 3. and out at the end of the inclined cylinder F. F. F. into *pout H.
The riddles G 1. G 2. G. 3. are made of one, two or three ply wire woven
diagonally onto a wire or iron frame as shewn by Fig. 3. and then bent into two
half circles or one complete circles so as to fix either inside or outside of
cylinder F. F. F. by means of bolts or screws.
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―
1. Moveable plates made of wood or iron so fixed with hinges inside of hopper
that as the cylinder revolves the plates will rise and fall by means of an eccentric
fixed onto the main shaft that works the cylinder and thereby prevents potatoes
and the like from lodging or choking as they fall from the hopper onto the moveable
mouthpiece.
2. Flanges fixed inside of cylinder in a slanting direction by bolts or screws the
flanges so fixed in a slanting direction that they clear away the potatoes from the
lip of the moveable mouthpiece and work them forward onto the first or dirt riddle
and as the inclined cylinder revolves the potatoes separate as they pass over the
other riddles and out at the end of the inclined cylinder.
3. Removeable riddles made of one, two or three ply wire woven diagonally onto
wire or iron frames made and bent into two half circles or one complete circle so as
to fix to either inside or outside of inclined cylinder by means of bolts or screws.
