the like from the Pods.
I, ROBERT KARGES of Brunswick in the Kingdom of Prussia & German Empire,
Inventor 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 machine forming the subject of the present application for Letters Patent
is devised for the removal of green peas and the like out of the pods by mechanical
means, and the separating of the same when shelled from the fragments of pods
and other rubbish with which they may be mixed, leaving them fit for consumption
or preservation.
The machine is designed to be driven by steam or other power, and is composed
of the following parts:
I. The rotary beater II A drum enveloping the rotary beater III A catching
arrangement, arranged so as to convey the freshly shelled peas and broken portions
of the pods into the separating or cleaning mechanism. IV The cleaning apparatus
laced below the shelling drum V. An outer cover enclosing the drum, the catching
arrangement and the separating mechanism.
Referring to the accompanying drawings, the rotary beater is arranged as
follows:- A shaft b rests on the two bearings a a. On this shaft are fixed two,
arms cc which bear two boards of soft wood d d fixed at a suitable angle. By
means of a pulley fixed on the end of the shaft b the same can be revolved at a
speed of from 500 to 600 revolutions per minute. II The drum. The framework
of the drum encasing the beaters, is formed of the two end rings ƒ f. Figs. 1. 2. and
3 fixed upon the shaft b within the bearings a a. Between the rings ff are fixed
at equal intervals rings g g g which however differ from the end rings in that they
have no spokes, but which have the same diameter as the end rings. This frame
is surrounded by a galvanised wire cage o of 1,4 millimetres wire gauze and of
suitable size of mesh The wire covering o is held by five rings h which are fixed;
over the wire cage o, the rings f f and rings gg. In the longitudinal direction
the wire cage is strengthened by five angle iron bars i placed at equal distances,
from each other.
All these parts are secured to each other by means of screws,
=

page_text: To the angle irons i are attached wooden laths 120 millimetres broad provided
with india rubber strips for the purpose of removing the peas and portions of pods
cast through the cover of the rotary beaters. The drum is closed by means of a
disc K Figure 3 through the centre of which runs the main shaft and by means of
a plate placed before the end ring f upon the shaft (Figure 3).
In the fixed plate K there is an opening into which the inlet funnel is secured.
The drum is set in motion by means of a belt passing over fin the same direction
as the shaft b and makes preferably 20 revolutions per minute.
III The catching mechanism. On the two interior broadsides of the iron cover
there is a rounded angle iron D affixed (Figure 1) which in its form corresponds to
the size and shape of the iron cover, and is prolonged to about of the space
vacant under the drum. In the middle of the cover, but at its front side viewed
longitudinally there is fixed in a similar manner a T iron bent into a circle and
which is secured by bolts to the adjacent cover. The two divisions formed on each
side of the T iron n and of the angle iron D D are filled up by two removable
curved plates.
If the rotary beaters and drum be now set in motion, and the pods to be shelled
passed into the drum through the funnel m, the pods are first attacked by the
beaters d d and projected around the wire cage in such a manner that they are
split open, and the peas escape therefrom and either pass directly through the wire
cage down to the separating mechanism, or are thrown against the outer envelope,
arrived at this point, the peas and any portions of pods or other rubbish which has
got mixed with them are stroked off by the india rubber shod boards already
described secured to the angle irons i, and conveyed to the separating mechanism,
whilst the empty shells fall out of the drum between the spokes of f f and the
plate 1.
IV The separating mechanism lies lengthwise under the drum at an inclination
within the metal cover e. It is worked by a crank arrangement forming the
driving mechanism, this arrangement consists of four smooth iron plates or
shovels E, F. G H which are provided with a connecting bolt J K L and M
(Figures 2 and 4) on each side. The shovels E F G H work on four slides N, O.
P. Q, which are secured lengthways in the interior of the metallic frame inclining
downwards. Under each shovel there is fixed a scraper R shod with india rubber,
for the purpose of removing the rubbish from the shovel beneath it.
The driving mechanism applied to the sifting mechanism rests on two sloping
barst placed below the metal cover which carry the bearings of two shafts ww
upon which shafts two cog wheels vv gearing into each other are placed. To each
end of the two shafts u u there is a crank S and T attached, these cranks by
means of draw bars X U and connecting rods Y and V are secured to the
bolts J K L which are attached to the shovels E F G. H which are thus set in
motion. 1. The shovel E sliding in guides N is actuated by means of crank S
draw bar X and bolt J.
2. The shovel F sliding in guide O is actuated by means of crank T bolt K and
connecting rod U,
3. The shovel G sliding in guide P is actuated by means of crank S, drawbar X
and bolt L
4. The shovel H sliding in guide Q is actuated by bolt M, connecting rod V and
crank T.
It is to be noted that the shovels E G move always upwards, whilst F. H are
moving downwards and vice versa. If now the shovels E G move upwards
and F H downwards, the pod fragments and refuse will be stroked off by the
india rubber strips which cause the removed refuse to fall onto the shovels F
and H.
Figure 4 shews one of the 4 plates of the propelling mechanism, which is
composed of the smooth iron plates E F G H (Figure 2) with their two pro-
jections qq (Figure 4) sliding in the grooves N O P Q. The plate is shewn in

page_text: Figure 4 broken off to save room, and is accompanied by a side view, in which
both the projections q and the guiding bars x are displayed in side view.
The removal of the pods lying on E is effected by the india rubber strip W
affixed to the lower edge of the cover, and the pods resting on G are removed by
the strip R attached to the underside of F. The peas themselves come out perfectly
clean sifted.
For the purpose of setting the sifting machinery in motion a driving pulley Z is
fixed to the shaft u. A machine such as is described can shell 100 kilos of pea
pods in 6 to 8 minutes.
V. The metal outer cover is composed of a sheet iron envelope covering the drum
of the catching. mechanism and the sifting apparatus, and is principally to retain
the peas thrown out with considerable force and to discharge them into the sifting
apparatus.
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 :-
1. For the shelling of green peas and the like an apparatus composed of
beaters c d d surrounded by a rotating sieve drum o arrangement, with or
without disc Z.
2. For the purpose of separating peas and the like from the fragments of pods,
which have passed through the sieve drum o, a series of plates or shovels actuated
by reciprocating crank mechanism in an inclined plane, up and down fixed grooves
or slides C, such for instance as the shovels marked E F G H with their bolts
and connections in combination with scraper bars R.
3. In apparatus for shelling peas and the like a catching device n fixed
concentrically about the metallic cover e and five scrapers i provided with an india
rubber strip fixed to the outside of the drum for the purpose of separating the
fragments of pea pods, which have passed through the drum to the sifting.
apparatus.
The whole substantially as described and shown in the accompanying drawings.
