slidingly adjustable plates which can be slid backwards and forwards and when the
position desired is attained, they are there fixed by screws so as to suit the variable
nature and dimensions of the vegetables to be shelled.
The shelling drum f, g, is covered by a metal table t, resting on the two plates a, a¹
having a longitudinal opening k, to allow the peas to fall through one by one as fast
as they are dropped on the table t, where they are led and prepared for distribution
either by hand or mechanically. A wire gauze sheet b, is placed in rear to prevent
the peas being thrown and to compell them to drop into the receptacle c. The pods
are led and heaped up in the part x.

COMPLETE SPECIFICATION.
Improvements in Machines for Shelling Peas, Beans, or similar
Vegetables in the Pod, whilst in a Green State.
I ARTHUR CHARLES HENDERSON of 46 Southampton Buildings, Holborn in the
county of Middlesex, and 31 Lincoln Place Dublin, Patent Agent do hereby declare
the nature of the said invention for "IMPROVEMENTS IN MACHINES FOR SHELLING PEAS,
BEANS, OR SIMILAR VEGETABLES IN THE POD, WHILST IN A GREEN STATE" and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement, a communication to ine from abroad by Alexandre
Sezille Chemist of the city of Paris in the Republic of France :-
The object of this invention is to shell or decorticate such vegetables as peas, beans,
haricots, or others in the pod whilst in a green condition, without in any way injuring

page_text: the peas, beans, or other vegetables by pressure. Eight times the quantity can be
shelled by these machines, than can be done in the same time by hand, by the most
skilled person,
the peas being ejected at ore side of the machine, and the empty pods
at the other.
Fig. 1 of the accompanying drawings shows a machine of the description embodying
my invention, seen in side elevation. Fig. 2 is a vertical section of the same taken
transversely with the axis. Fig. 3 is a general plan. Fig. 4 is a part shown
in detail.
The frame consists of two sheets or plates of cast- or other iron a. a' connected by
three tie rods e. e¹ e², and furnished below with lugs, or ears a² a³, by which it is
united and fixed where most convenient.
The plates a. a' are at a certain height pierced with holes, and bear if necessary
cushions, or supports in which the horizontal axis d, of the cylinder f, revolves, the
periphery of which is furnished with a casing or jacket 9, of india rubber or other
suitable material, having longitudinal ribs or projections g¹, of suitable height, and
arranged at convenient distances apart.
The shaft d, on one or other of its ends which project beyond the plates a. a², may
be supplied with a crank handle M on either side according as it is turned by the
right or left hand.
The cylinder f, with its ribbed envelope g; at its rear is surrounded with a grating h,
of wire thread, forming a square mesh of 12 to 16 millimètres for shelling the peas.
This grating is within a frame h. h¹, at its sides, and supported above and below by
the traverses or bars m. m¹ n. n¹ resting and sliding in the inclined mortises of the
sides of the frame a. a¹. The bars m. m¹ n. n¹ are connected to india rubber or other
springs o. p. lodged in the mortises, these springs may be made to act either by expan-
sion or contraction, their object being to draw the grating against the cylinder or
drumf, with its ribbed elastic case g, and also allow it to separate therefrom in any
direction and distance necessary in the passage of the peas to be shelled, so as to
prevent any possibility of crushing them."
The minimum distance of the grating (the threads or wires of which may be
coated with india rubber) is determined by the abutting of the bars m. m³ n. n¹
against the plates q. q' vide Fig. 4, covering the slots or mortises in the plates a. a¹,
and sliding as required either backwards or forwards, so that they can be regulated
and fixed by screws r, in the desired position to suit the variable nature and dimen-
sions of the vegetables to be shelled.
The shelling cylinder or drum f. g. is covered with a metal table t, resting on the
two plates a. a¹ in which is a longitudinal opening k, to allow the peas in the shell
to fall through one by one, as fast as they are pushed from the table t, where they are
previously led and prepared for distribution either by hand or mechanically.
A wire gauze sheet 6, is placed in rear to prevent the peas being thrown, and to
force them to drop into the receptacle or drawer c.
The empty shells are led to, and heaped up in the part x.
The action of the machine is as follows:-The peas whilst in the pod are led, or
placed on the table t, by hand or mechanically as just observed, or by aid of a sieve or
some equivalent contrivance, they are methodically arranged side by side, so as to
allow them to fall in succession through the orifice k, which runs lengthways, and
parallel with the shelling cylinder, or dum f. which latter is animated with a rotary
motion by turning the handle M, then the peas which lodge between the sides 9. g¹
are pressed to the bottom of the longitudinal cavities of the elastic envelope g, by
means of the metallic threads of the grate h. This pressure which can be easily
regulated, has the effect of rolling and opening the pods, finally compelling the peas
to escape, and then fall into the drawer or receptacle c, whilst the empty pods do not
leave the grating h, till they have advanced further, to be heaped up at x. whence
they are easily removed.
The springs connected to the grating top and bottom may be of india rubber, metal,
or other suitable substance, or they may be replaced by counterweights, provided the
elastic action is sufficient to produce the desired effect viz: the shelling of the peas
1

page_text: in conjunction with the ribbed cylinder f. 9. at the same time allowing of the with-
drawing of the grating from the cylinder when a certain resistance occurs insufficient
however to crush the peas.
Motion is communicated to the cylinder f. g. either by hand as represented in the
drawings, by the foot, or by any convenient mechanical means; in like manner the
peas may be distributed and fed to the machine.
The pea sheller may be constructed or arranged so that one, two, or more pea pods
can be received along the ribs of the shelling cylinder according to the quantity of
peas required to be shelled.
The grating h, can be placed at the side, or below the cylinder, or in any convenient
position.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
1st. The combination (in a machine for shelling peas and so forth such as herein
described) of a cylinder or drum f with an elastic jacket g and ribs gl, in conjunction
with the concentric grating h, with variable sized mesh, the metal wire forming it
being either coated or not, with india rubber, or other elastic substance, the grating
being pressed or drawn against the periphery of the cylinder f, by aid of the
springs o. p. of metal or india rubber suitably disposed, the shelled peas passing
through the mesh of the grating in the manner and by the means herein set forth.
2nd. In a machine such as described, the arrangement of the distributer t, which
by hand or mechanically distributes the peas in the pod, one by one to the shelling
drum f, the grating h. with elastic pressure on the cylinder; the drawer c, which
receives the shelled peas, whilst the shells are ejected in any convenient direction.
3rd. The application of this machine either for shelling or decorticating peas,
French, or broad beans, coffee berries, cocoa pods and so forth.
4th. The application of india rubber to the cylinder f, for pressing on the grating h,
whose wires may or may not be coated with india rubber or some elastic substance.
5th. The right to arrange the machine vertically, horizontally or inclined, as well
as to work it by hand, mechanically or otherwise.
