PROVISIONAL SPECIFICATION left by the said James Henry Channing
Martin at the Office of the Commissioners of Patents on the 4th December
1883..
JAMES HENRY CHANNING MARTIN of "The Drive," Walthamstow in the County
of Essex IMPROVEMENTS IN MACHINERY FOR DECORTICATING OR SCOURING RICE,
WHEAT AND OTHER GRAIN AND SEEDS.
The Invention has for its object improvements in machinery for decorticating or
Scouring rice, wheat and other grain and seeds.
For this purpose I employ a stone or an emery drum revolving rapidly within
a case cylindrical therewith either perforate or not (when perforate such case is
caused to revolve on fixed ends) and set at an angle of preferably about 45 degrees
in a suitable frame.
The lower end of the case is provided with an outlet aperture and regulating
slide at or near the bottom of the circumference and in the upper end at or near
the crown is an inlet aperture large enough for sufficient grain to pass in to keep
the machine full. The advantages of the machine are as follows:-
A decorticating or scouring machine set obliquely or in an angular position but
having the output regulated by the outlet and kept full increases its capacity by
bringing the whole working surface into continual action and causes a considerable
friction of grain against grain and prevents the dashing about of the grain which
is so productive of breakage, waste in meal and unevenness of sample.
A decorticating or scouring machine of the character described by being set
obliquely or in an angular position causes the pressure of the grain to be more
uniform, the weight being borne by the drum and case proportionately, thus avoiding

page_text: the undue pressure at the bottom of either a vertical or horizontal machine working
full and having the output regulated by the outlet and thus reducing the breakage
of the grain.
The scouring action upon the grain is so uniform that rice may be only slightly
cleaned and yet a perfectly even sample produced or it may be cleaned to the
highest point.
For wheat this machine can be regulated to act as a smutter only or to clean
thoroughly and especially the ends of the grain, and produce the condition so
desirable for the comparatively new system of roller milling, the skin in the crease
being left thicker than any other portion and therefore more easily separated, the
power required for the break rollers being greatly reduced.
This machine takes very little power in proportion to the work done.

In the event of the case b being a fixture, the gearing. for giving motion thereto
will be dispensed with and the shaft a¹ will be driven as shown or by other suitable
means.
.
Having thus described the nature of my said invention and the mode in which
I carry the same into effect I would have it understood that what I claim in a
machine for decorticating or scouring rice wheat and other grain and seeds, is
First a drum a rapidly revolving within a case b concentric therewith and set
at an angle preferably of about 45 degrees, such case 6 being perforate or not and
either stationary or caused slowly to revolve on fixed ends b. b. provided with
inlet hole 6 hopper 6 outlet hole 63 and regulating slide 6 substantially as herein
shown and described and, for the purpose, stated, and
Second a machine for decorticating or scouring rice wheat and other grain and
seeds in which the drum and case are set at an angle and the machine is worked
full substantially as herein shown and described and for the purpose stated.
In witness whereof I the said James Henry Channing Martin have hereunto set
my hand and seal this Twenty eighth day of May in the year of our Lord One
thousand eight hundred and eighty four.
