I, WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A. of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool, in the County of Lancaster, and
323 High Holborn, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said invention for "IMPROVEMENTS IN COMBINED SHELLING AND
GRINDING MACHINES APPLICABLE FOR TREATING GRAIN AND THE LIKE" (a com-
munication from abroad by Messieurs Aebi and Muehlethaler, of Burgdorf in the
Republic of Switzerland, Engineers) to be as follows:-
This invention relates to a machine which is applicable for use as a combined
shelling and grinding machine.
The shelling apparatus consists of a series of shelling plates in order to obtain a
close fit; two of which are provided on their circumferences with flanges. The
shelling plates are covered on their shelling surfaces with rasping plates. One
plate is secured to the frame of the apparatus by means of screws. Opposite to
the shelling plates rotate the running plates, which are also covered on one side
with rasping plates. Creepers, cast in one piece with these running discs, are
disposed on the naves of the discs. The discs respectively the creepers are coupled
by means of clutches gearing together.
The grain to be shelled arrives through a funnel by means of a creeper between
the shelling plate and running plate, and thence over the exterior flange of the
running plate into the space between the same, whence it is conducted to a worm
by means of a spirally shaped rib on the back side of the running plate. From
here the grain arrives in the same way into the space between the second and third
sets of plates from which it falls into the discharging funnel. To regulate the
entrance of the grain to be shelled, the slide valves are disposed in such a way,
that they can be moved by means of the worm, worm-wheel and toothed wheel.
The inlet opening can thus be modified at will, and the entrance of the grain can
consequently also be regulated.
t
To move the separated hulls and impurities if any, out of the case of the running
discs, and to separate therefrom at the same time the shelled grain, exhausting
apparatus are disposed on the said case, which lead away the impurities. Only
the clean shelled grain falls therefore out of the discharging funnel of the shelling

page_text: apparatus without any admixture. The exhausting apparatus serves also to dry
the grain during the shelling operation which has been previously moistened. For
this purpose inlet-openings for air, which are covered with perforated plates, are
arranged in the case of the shelling apparatus. On the nave of the disc is placed
the regulating contrivance of the running discs. The running discs, which are
secured to the shaft are approached to or removed from the shelling plates by
displacing the same in the longitudinal sense by means of the regulating
contrivance.
The construction of the grinding apparatus is similar to that of the shelling
apparatus. The grinding plate and the running plate are provided with ribbed
steel rings. The regulation of the running disc is effected in the same manner as
in the shelling apparatus, by displacing in a longitudinal sense the shaft to which
the running plate is secured..
The entrance of the grain from the inlet funnel into the space between the
grinding plates is regulated in the same way as in the shelling apparatus by means
of outward adjustable sliding valves.
The grinding plates consist of rifled rings which may easily be exchanged and
sharpened when they have become blunt. The rings are sharpened on the planing
machine by means of a chisel.
The two apparatus, grinding and shelling apparatus have a common impelling
plate consisting of two halves which gear together in the same way as clutch
couplings. The clutches thus allow the shafts to be longitudinally displaced in
order to regulate the two apparatus.

I, WILLIAM PHILLIPS THOMPSON Fel. Inst. P.A. of the Agency for Foreign
Patent Solicitors 6, Lord Street Liverpool, in the County of Lancaster and
323 High Holborn in the County of Middlesex Civil Engineer do hereby declare
the nature of the said invention for "IMPROVEMENTS IN COMBINED SHELLING AND
GRINDING MACHINES APPLICABLE FOR TREATING GRAIN AND THE LIKE (n com-
munication from abroad by Messieurs Aebi and Muehlethaler of Burgdorf in
the Republic of Switzerland, Engineers) and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
•
"
The invention consists in certain improvements in machines for, shelling and
grinding corn, whereby the hulls may be readily removed and the grain rapidly
conducted between the hulling surfaces, and whereby the grinding faces may be

page_text: readily repaired, and whereby either the hulling or the grinding portion of the
apparatus may be adjusted without necessarily disconnecting it from the other and.
without the use of more than one driving belt.
The machine is represented in the Figures 1 to 6, sheet, I and II of the annexed
drawings in which Figure I (sheet I) shews & longitudinal section of the apparatus.
Figure 2. (sheet II) is a side view thereof.
Figures 3 and 4 are sections on the lines P P and P¹ P₁ respectively of the
Figure 1.
Figure 5 is a view of the disc of the grinding apparatus.
Figure 6 is the regulating contrivance of the shafts N N.
As shewn in Figure 1. sheet 1, the shelling and grinding apparatus are connected
together upon one frame or foundation. The shelling apparatus consists of the
shelling plates F H and H; the two latter plates H and H' are provided on their
circumferences with flanges forming circular chambers between the plates.
The shelling plates are covered on their surfaces with rasping-plates. E is the
inlet funnel of the shelling apparatus. The plate F is secured to part of the.
frame S' of the apparatus by means of screws.
Opposite to the shelling plates rotate the running discs G G¹ each covered on one
side with a rasping plate.. Spiral feeding screws or flanges are cast or otherwise
disposed on the hubs of the running discs G GG". The discs and spiral feeding
screws of the running discs catch like clutches together and are thus coupled
(Figure 1). The first disc G is secured to the shaft N by means of a through-
passing peg k, whilst the disc Q" is fixed by means of a screw p. The intermediate
disc G is maintained by the two exterior discs G and G" by means of the clutch-
coupling.
A funnel E formed by the frame contains the grain to be shelled which grain is
conducted by means of the screw S to the space between F and G and passes
thence over the periphery of G and H into the space between G and H whence it
is conducted to the screw S by means of the spirally shaped rib M on the back
of G. From here the grain passes in the same way into the space, between the
plates Hand G¹ and Hand G and then into the discharge. To regulate the
entrance of the grain to be shelled the slide valves xx (see Figures 1 and 5) are
used consisting of two guide plates disposed in such a way that they can be moved
vertically to and from each other by means of toothed pinion engaging with racks
on the plates. The inlet-opening to the plates H and G can thus be modified at
will and the entrance of the grain can consequently be regulated.
To move the separated hulls and impurities, if any, out of the case of the running
discs to separate therefrom at the same time the shelled grain, the air is exhausted
from the said case, which air carries with it the aforesaid impurities, that only the
clean shelled fruit may pass to the discharging funnel of the shelling apparatus
without any admixture. The exhausting of the air has at the same time the effect
of drying the grain during the shelling operation, for which purpose the air
openings in the case of the shelling apparatus are covered with perforated plates.
The running discs which are secured upon the shaft N are moved from and to the
shelling discs by moving the same longitudinally by means of the adjusting
contrivance.
The regulating contrivance is as follows; The nave J is threaded, and grooves
are cut into the threads. A ring v which has projections catching into the
grooves 1,., is placed on the nave. A socket D, provided with a hoop D¹ is screwed
upon the thread of J, so that the clutches f embrace the ring v, after having passed
through recesses arranged in the said ring v. By screwing the screws i, i, the
socket D is secured against loosening. The shaft N passes through the socket D,
and meets with a counter pressing screw P. The two parts N and P are secured
against any longitudinal movement by nuts and counternuts. If the shaft N is to
be moved in the longitudinal direction, the nuts on N and P. are loosened and the
longitudinal motion is effected; whereupon the position of N and P is fixed again
by screwing the nuts.

page_text: The construction of the grinding apparatus is somewhat similar to that of the
shelling apparatus. The grinding plate D and the running plate E are provided
with ribbed steel rings (Figure 5).
The regulation of the running disc E is effected by a similar contrivance as has
been described for the shelling apparatus by moving longitudinally the shaft N to
which the running plate is fixed.
The entrance of the grain from the inlet-funnel into the space between the
grinding plates is regulated in the same way as in the shelling apparatus by means
of adjustable sliding valves a¹. The grinding discs consist as shewn in Figure 5 of
ribbed rings, which may easily be exchanged and sharpened when they have
become blunt. The rings are sharpened on a planing machine by means of a chisel.
The two apparatus are simultaneously driven from a pulley which consists of two
parts L L gearing together like clutch couplings. The clutches thus allow a longi-
tudinal movement of the shafts in order to regulate the two apparatus.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed as communicated
to me by my foreign correspondents I declare that what I claim is :-
.
A combined shelling and grinding apparatus consisting of
1st. A shelling apparatus characterised by the arrangement of a series of plates
or discs F G, H G; H G, arranged side by side on the same shaft and covered on
the working surfaces witn rasping plates in combination with feeding screws S S
and spiral feeding ribs for conducting the grain from one pair of discs to the other,
the regulation of the running discs being effected by moving the common shaft N
longitudinally and the entrance of the grain being regulated by the sliding
valves xx.
2nd. A grinding apparatus consisting of grinding and running discs D and E
arranged upon a shaft, the surfaces of these discs being formed by concentrically
arranged ribbed steel rings, the entrance and regulation of the grain being effected
in the same way as in the above described shelling apparatus, substantially as set
forth.
