tage, from time to time coming, growing, accruing, and arising by reason of
the said Invention, for and during the term of years therein mentioned,
to have, hold, exercise, and enjoy the said licence, powers, priviledges,
and advantages, therein-before granted or mentioned to be granted unto me,
the said William Winlaw, my executors, administrators, and assigns, for and
during and unto the full end and term of fourteen years from the date of the
said Letters Patent next and immediately ensuing, and fully to be compleat
and ended, according to the Statute in that case made and provided; in which
said Letters Patent there is contained a proviso obliging me, the said William
Winlaw, by an instrument under my hand and seal, to cause a particular
description of the nature of my said Invention, and in what manner the same
is to be performed, to be inrolled in His Majesty's High Court of Chancery
within one callander month next and immediately after the date of the said
Letters Patent, as in and by the same (relation being thereunto had) may
more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Winlaw, do hereby declare that the said Invention consists and is
performed in manner following, viz:-
The explanatory part of William Winlaw's Conical Spiral Mill for Seperating
the Grains of Corn from the Ends.-A, A, A, A, the frame, which contains the
conical mill and female fluted cone and nutt. B, the conical part which is cut
in that fluted manner, as represented in the Drawing, which, according to the
seale, is one inch and a quarter to a foot. The flute or channel, which performs
the operation of rubbing out the grain, is three quarters of an inch broad, and
of sufficient depth as not to bruise a grain of wheat; and the angle of the spiral
is the same as represented in the Drawing, and it will make no difference in
the operation if they are more or less spiral. C is the iron wheel fixed upon
the spindle, which passes through the inner nutt, and is fixed firmly into the
same; the diameter is seventeen inches, with fifty-one teeth. The pinion E,
which turns the wheel, is six inches diameter, and seventeen teeth, and is fixed
upon the axle, which the fly that is fixed upon by the cross bearing barrs with
wedges, to allow the wheel and pinion to be raised up occasionally, to admit
larger or smaller grain, and is regulated by the screw D, which passes through
the bridge or cross rail at the bottom of the nutt. F is the shoc, where the
ears of corn, after cut from the straw, is put, and feeds the mill; it is poised
upon two cords, and these are regulated by two round wood pins, which is
turned round occasionally to feed the mill faster or slower as occasion may
require. H, the fly upon the spindle, is in diameter three feet nine inches,

page_text: more or less will answer. G is the spreading part of the cone or hopper,
which receives the ears from the shoe and conveys them into the body of the
mill. I, the upright coggs which gives motion to the shoe F, and thereby
supplies the mill in the same manner as mills in common are supplied. The out-
ward cone and also the nutt are made of oak; the outward one is hooped in the
same manner as tubs or casks are in common, and made of staves in the samo
manner, being properly jointed and glued together; the inner one has a strong
plank at bottom, and the same at top, of unequal diameters, according as is
represented in the Drawing, and the staves are jointed and glued thereon, and
also nailed to the inward planks at top and bottom.
In witness whereof, I have hereunto set my hand and seal, the Twentieth
day of July, in the twenty-fifth year of the reign of our Sovereign
Lord George the Third, by the grace of God of Great Britain, France,
and Ireland King, Defender of the Faith, and so forth, and in the
year of our Lord One thousand seven hundred and eighty-five.
