MACHINE FOR HULLING NUT MEATS FROM
'
THEIR SHELLS
'
Isadore J. Fisher, Dallas, Tex.
Application June 8, 1937,: serial'No. 147,103
6 Claims. ' (01. 146-8)
This invention relates to a machine for hulling
nut meats from the shells;
More speci?cally, the invention relates to a
machine for hulling the meats from the shells of
5 nuts, particularly pecans ‘which have been pre
viously cracked either by hand or by machine.
It is well known that the act of hulling the
meats from the shells of nuts and particularly
pecans, regardless of the care exercised in crack
10
ing the nuts, is monotonous, tiresome, and time
consuming when done-by hand which has hereto
fore been the usual practice.
A primary object of the present invention is
the provision of a machine capable of hulling the
15 meats from the shells ‘of a large quantity of
cracked nuts in a relatively short period of time.
A further object of the invention is the provi
sion of a machine embodying a plurality of beat
ers and means for feeding the cracked nuts by
Each of'the bolts 22 is threaded ‘
into the floor I6 and a relatively heavy coil‘spring
‘23 encircles'the bolt with its opposite ends engag
ing thefloor I6 and bar 2| for maintaining the
bar in engagement with the head of the bolt 22.
The bolts 22 may be replaced'by studs rigidly‘
fixed‘ in the floor I6 and having nuts onthe
nuts eifect substantially complete separation of
wood.
'
A still further object of the invention is the
25 provision of a machine as a means for separating
.
'
the meats from the shells of cracked nuts which
bar as is" more clearly indicated in Fig. 2..
Journalled in ‘the bearings 24 are the reduced
ends 25 of rollers 26 and 21 which, in keeping
with the varied spacing of‘ the bearings 24 on

I
With the above objects in view, as well as others
3 6 which will become obvious in the course of the
following disclosure, reference will be made to
the accompanying drawing, forming part of same,
and wherein '
‘
Figure l is a side elevational view of a machine
constructed in accordance with a preferred em
bodiment of my invention.v
Fig. 2 is a right end elevation of the machine
as illustrated in Fig. '1. >
'
Fig. 3 is a longitudinal section viewed from the
opposite side of the machine as illustrated in
Fig.
1.

'
'Fig. ‘4 is an enlarged view partially in section
and partially in elevation, disclosing the preferred
45 means for journalling the rollersembodied in the
machine.
Fig. 5 is an end elevation of ‘one of the rollers
on an enlarged scale.
-
Fig. 6 is a side elevation of one of the inserts
or beaters embodied in the machine.
Referring to the drawing by reference charac
ters, and wherein like characters designate like
parts, I0 designates a frame which may be of
any suitable materialand construction for sup
porting an inclined trough or chute I I.
'
The frame I0 as illustrated embodies a pair of
relatively long legs I2 for supporting the higher
end of the chute I I and a pair of relatively short
legs l3 for supporting the lower end of the chute
II, the frame further embodying a pair of later
is:
Secured to each of the bars 2I is‘ a 'pair of
bearings 24, the bearings on one of the bars being
closer each other thanthe bearings, on the other
is simple in construction, effective in operation,
and is capable of being manufactured and sold
at relatively low cost.

disposed a motor support I5. While the chute I I
is disclosed as being‘ supported on the legs. I2:
and I3 in a ?xed inclination, suitable means may
be provided for adjusting such inclination.
The chute I I embodies a floor I6, opposite sides
II of a suitable height, ends I8 and I9, and a
removable cover 20. Disposed within the chute
I I closely adjacent the sides I1 is a pair'of bars 2I
each of which is adjustably supported in verti
cally spaced relation to the floor I6 by bolts ‘22'
adjacent the ends thereof, as is more clearly illus-l
successive impacts of the heaters on the cracked
20 gravity to the heaters in succession whereby the
3'
ally spaced horizontal members I4 on which is
'
'
bars 2I,‘are inclined relatively to each other and
the ends I8 and I9 of chute I I, as is clearly indi
cated in Fig. 2.
‘
'
The reduced ends 25 of the rollers 26 and 21 >
at the adjacent or nearer ends thereof project
through‘the adjacent'side I1 and have ?xed 35
thereto grooved pulleys 28 and 29 which are oper
atively engaged by a V-belt 30 for transmitting
rotation of roller 21 to roller 26.
* -
'
'
Fixed to'extension 25 of roller 21 adjacent to
and ‘outwardly of pulley 29 is a grooved pulleyv
3|“ which is operatively engaged by a V-beltl32
which also operatively engages a grooved pulley
33 on an electric motor' 34 suitably secured» to
the support I5. The lower end I9 is provided
with discharge openings 35, and a suitable dis 355
charge trough ‘36 is provided which opens through
the side I'I above the lower end of roller 21. ,
'
As is clearly illustrated in Fig. 2, the roller 26
is inclined downwardly toward the belt drive while
roller 21 is inclined downwardly away from the 50
belt drive; This may be reversed, however, it
being sui?cient only that the rollers be inclined
whereby nuts fed into the upper end of the'chute
I I will travel by gravity toward the lower end'of
the chute along the successive rollers.
)
55
The roller 26 is provided adjacent its lower end
with a reduced portion 31 providing a nut exit
Opening and each of the rollers is provided with
diametrically disposed inserts or heaters 38 which
may be constructed of wood, leather, steel or any 60
