Improvements in Apparatus applicable for Grinding the Kernels of
Nuts or other Material.
A communication by JOSEPH LAMBERT, of Battle Creek, in the County of Calhoun
and the State of Michigan, United States of America.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester,
both in the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick, and 322, High Holborn, in the County of Middlesex, Civil Engineer,
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:-
This invention relates to a new mill for making nut butter, which is a pasty or
plastic substance made by grinding the kernels of nuts in various ways.
It is the object of the invention to provide a simple and efficient machine which
will reduce the kernels of nuts, such as peanuts or nuts of any description or
material of similar consistency, to an impalpable pulp. A further object in the
construction, is to provide improvements and features in the mill which shall
make it very speedy and efficient in its action.
The objects of this invention are accomplished by the devices and means
described in the specification. The invention is clearly defined and pointed out
in the claims. The structure is fully illustrated in the accompanying drawing,
in which:
Fig. 1 is a detail view, the casing and crank hanger being shown in vertical
longitudinal section.
Fig. 2 is a longitudinal sectional detail view of the casing alone.
Fig. 3 is a transverse detailed sectional elevation through the head, taken on a
line corresponding to line 3-3 of Fig. 1.
Fig. 4 is a detail longitudinal sectional view of a modification.
Fig. 5 is a sectional view similar to Fig. 2 of the modified casing.
In the drawing similar letters of reference refer to similar parts throughout
the several views.
Referring to the lettered parts of the drawing, A is the standard which supports
the machine provided with a suitable thumb screw H, to clamp to a suitable
table or bench, as G. A¹ is the barrel of the casing which is expanded into a
funnel shape towards the front at A". The interior of this shell is provided
with ribs e, extending longitudinally and spirally towards the front or dis-
charge end of the casing. The interior of the casing at the front or discharge end
is provided with a smooth rubbing surface. Within this casing is a grinder
head which is provided with coarse screw threads b, which fit sufficiently close
to the ribs within the casing to co-act therewith in forcing any material forward
within the same. This head is provided with a smooth conical portion C",
towards its outer end, fitting closely the smooth rubbing portion of the casing.

page_text: Little grooves a, are cut into this casing, having cutting edges to the rear side
to assist in cutting and crushing the material within. They are also placed
at an angle to the axis of the said head so that they serve to force any material
within, forward. These correspond with similar grooves in the smooth portion
of the casing at this point and serve to force the material through the same.
The rear end of the grinder head is provided with a journal C³, fitting a suitable
journal bearing in the casing and extending out to receive a crank F. The
crank F, is adjustable thereon, sliding on key d, and is adjustable to put tension
on the head by the thumb screw E.
In Figs. 4 and 5 modifications are shown in which the entire casing is a portion
of the surface of a cone, the structure of the shell fully appearing in Fig. 5.
While the main parts of the device are shown, made up practically of two
pieces, my correspondent desires to state that they might be made up of sections.
and other means be provided of operating the same, and that the grinder might
be actuated by other means than the crank. The casing is provided with a
hopper B, to receive the material to be operated on.
In operation, nut meats or any other material required to be reduced to butter
or pulp, is placed within the hopper B, the crank rotated, when the screw will
take the material up, crushing and breaking the same until it comes to the
small grooves a, when it will be further cut up and ground and forced out between
the smooth rubbing surfaces at the forward end of the grinder and casing, and be
discharged as a pulp or butter. In this connection, it may be remarked that the
notches a, are not absolutely necessary to the production of the butter, but by
placing them in the head, it is possible to operate the machine to produce butter
two or three times as fast as it would be otherwise. The rubbing surface is pre-
ferably conical on account of adjustment but would be operative in any form.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed as communicated to
me by my foreign correspondent, I declare that what I claim is:-
-
1. In a mill for grinding nuts or for similar purposes, the combination of a
casing with a hopper at its rear end, with internal grooves within the same
leading toward the forward end and provided on its interior with a smooth
rubbing surface; a grinder fitting within said casing, provided with a coarse
screw thread extending across the grooves of said casing and with its forward end
enlarged in conical form and provided with a smooth rubbing surface correspond-
ing to the rubbing surface of said casing; and means for rotating the grinder
within said casing, co-acting for the purpose specified.
2. In a mill for grinding nuts or for similar purposes, the combination of a
casing with a hopper at its rear end with internal grooves within the same
leading toward the forward end and the forward end provided on its interior
with a smooth rubbing surface; a grinder fitting within said casing provided
with a coarse screw thread extending across the grooves of said casing with its
forward end provided with a smooth rubbing surface corresponding to the rub-
bing surface of said casing: the means of rotating the grinder within said casing,
co-acting for the purpose specified.
3. The combination of a suitable casing A¹, having an enlarged projecting
funnel shape portion A", smooth at the front, which are provided with suitable
spiral grooves with a hopper B, to the rear thereof; and a grinder head C, with
an enlarged conical portion C", containing a spiral thread and notches a, and
adapted to fit the outer portion of the casing A", and the screw portion fitted
against the corresponding part of the casing; the said grinder having a journal C',
projecting through the casing on which is adjustably secured a crank F, for put-
ting tension upon the grinder and its casing.
4. The combination, in a grinding mill for grinding nuts or similar material,
of an outer casing containing spiral grooves with a smooth portion at the front
and with a hopper to feed the same at the rear, and a screw within the same,

page_text: having a smooth portion adapted to fit the smooth portion of the outer casing,
the said casing and grinder being provided with screw threads as aforesaid,
fitting against each other, and with additional angular notches to receive the
kernels and force them through the smooth portion, as specified.
5. In a machine of the class described, the combination of an outer casing with
ribs therein, with smooth rubbing surface to the front thereof; and a hopper at
the rear; a grinder head within the same with a coarse screw thread and extend-
ing forward into a smooth portion to fit corresponding portion of the casing; the
said grinder head being provided with grooves extending longitudinally, having
an angular portion at the back of each groove to serve as a cutter to crush material
within the grinder, for the purpose specified.
