A NEW OR IMPROVED MACHINE OR APPARATUS FOR DISINTEGRATING OR CRUSHING GRAIN AND SEEDS
Year: 1878

page_text: LETTERS PATENT to Joseph Addey Fawcett, of Wakefield, in the County of
York, Corn Miller, for the Invention of "A NEW OR IMPROVED MACHINE OR
APPARATUS FOR DISINTEGRATING OR CRUSHING GRAIN AND SEEDS."
Sealed the 12th July 1878, and dated the 15th January 1878.
PROVISIONAL SPECIFICATION left by the said Joseph Addey Fawcett at
the Office of the Commissioners of Patents on the 15th January 1878.
JOSEPH ADDEY FAWCETT, of Wakefield, in the County of York, Corn Miller. "A
NEW OR IMPROVED MACHINE OR APPARATUS FOR DISINTEGRATING OR CRUSHING
GRAIN AND SEEDS."
This Invention consists in the employment of a new or improved machine for the
purpose of crushing or bursting grains or seeds, and is intended to be used separately
and also in combination with or as a preparing machine for millstones, rollers,
centrifugal or other disintegraters or attrition mills.
The machine consists of one or more pairs of jaws, one jaw of each pair being
moveable by eccentric or other mechanical equivalent. The jaws may have simple
or graduated flutings or corrugations. If graduated the portions which receive the
grain or seed on its entrance are sharp or angular, but are softened down towards
the bottom into dull curves.
The distance between the jaws may be regulated by means of set screws so as to
render them applicable to grain and seeds of all sizes, and may be employed for
operating upon semolina or other component parts of grain. They may also have a
rubbing or grinding action imparted to them as well as the crushing or squeezing
motion, and may be composed either of metal, earthenware, glass, or other suitable
substance.

the said Joseph Addey Fawcett in the Great Seal Patent Office on the 15th

JOSEPH ADDEY FAWCETT, of Wakefield, in the County of York, Corn Miller. "A
NEW OR IMPROVED MACHINE OR APPARATUS FOR DISINTEGRATING OR CRUSHING
GRAIN AND SEEDS."
This Invention consists in the employment of a new or improved machine for the
purpose of crushing, bursting, or breaking up grains or seeds, and is intended to be
used separately, and also in combination with or as a preparing machine for mill-
stones, rollers, centrifugal or other disintegraters, or any other reducing mills.
The machine consists of one or more pairs of jaws, one jaw of each pair being
moveable by eccentric or other mechanical equivalent. The jaws may be plain, or
they may have simple or graduated flutings or corrugations;, if graduated, the
portions which receive the grain or seed on its entrance are sharp or angular, but
are softened down towards the bottom into dull curves.
The distance between the jaws may be regulated by means of set screws, so as to
render the machine applicable to grain and seeds of all sizes, and may be employed
for operating upon entire grains or upon component parts thereof. They may also
have a rubbing or grinding action imparted to them as well as the crushing or
squeezing motion, and may be composed either of metal, earthenware, glass, or other
suitable substance.

In order that my Invention may be more fully understood I herein give reference
to the accompanying Sheet of Drawings illustrative thereof.
Fig. 1 is a front elevation of my machine; and Fig. 2 is a sectional elevation of
same.
A is a bed or framework upon which are fixed two side plates B. By means of
grooves C these side plates hold in position a metal block D. E are metal jaws or
beaters, which are mounted on eccentrics F'formed on the shaft G, being steadied
at the lower edge by lugs a, which rest within grooves formed in the plates H. The
plates are capable of being moved nearer to or further from the block D by
means of screw J and wheel K, by which movement of the jaw is slightly altered,
and the distance between the jaws and the metal block when working can be
regulated by means of the supporting screw L, which raises or lowers the block in
the grooves C according as it is desired to increase or decrease the space.
Grain is fed to the machine by the hopper M, and as it gravitates betwixt the
moveable jaws E and the metal block or fixed jaws D it is subjected to a succession
of crushing and rubbing operations, the number of which will depend upon the
speed of the machine and the space or opening betwixt the jaws.
As herein-before stated the jaws may be either plain or they may be corrugated,
as in Fig. 3, which is a detail plan, view shewing one pair of faces corrugated and
the other plain.
-
The jaws E instead of being mounted on the eccentrics F may be hinged at either
top or bottom, and worked by eccentric or crank and connecting link, in which case
the action of the jaw will be simply percussive and not rubbing.
Having thus described the nature of my Invention I would have it understood
that I do not confine myself to the precise details, herein shewn with regard to the
form and construction of the machine, as the same may be varied without departing
from the principle thereof; but what I claim as my Invention and consider to be
new is, the construction and employment of machinery capable of operating upon
grain or seed by successive percussive or crushing and rubbing actions, or per-

page_text: cussive or crushing actions only, substantially as and for the purpose herein shewn
and described.
In witness whereof, I, the said Joseph Addey Fawcett, have hereunto set my
hand and seal, this Eleventh day of July, in the year of our Lord One
thousand eight hundred and seventy-eight.
JOSEPH ADDEY FAWCETT. (L.B.).
