page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
WELDON, of Litchfield, in the County of Stafford, Engineer, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-second day of December, in the Thirty-eighth year
of His reign, give grant unto me, the said James Weldon, His especial
licence that I, the said James Weldon, during the term of years therein
mentioned, should and lawfully might use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "A CERTAIN
MACHINE OR MILL POR BREAKING, GRINDING, AND PULVERIZING OF HATCHED OR
CHOPPED BARK FOR TANNING, AND FOR BREAKING, GRINDING, AND PULVERIZING
DIFFERENT KINDS OF WOOD AND OTHER HARD SUBSTANCES, FOR GRINDING APPLES,
AND WHICH MAY ALSO BE APPLIED TO VARIOUS OTHER USEFUL PURPOSES;" in
which said Letters Patent there is contained a proviso, obliging me, the said
James Weldon, by an instrument in writing under my hand and seal, to
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 calendar month after the date of the said
recited 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
James Weldon, do hereby declare that my said Invention is described as
follows, that is to say:-
To explain more fully the principles of my Invention as they may be
applied to a mill for breaking, grinding, and pulverizing batched or chopped

page_text: bark for tanning and other uses, for breaking, grinding,-and-pulverizing wood
and other hard substances, and for grinding of apples, I have annexed a
Drawing, which the following description is intended to elucidate -A is a
piece of timber, connected to the sides of the mill house to receive the upper
gudgeon of the shaft; B, an iron or metal plate in which the gudgeon is to
work; C, the upper gudgeon let into the body of the shaft, as shewn by the
dotted lines; D,. the shaft, which may be of an octangular or any other form;
E, the lever or shaft to which the power for working the mill is to be applied,
and which may be continued to the length necessary for obtaining sufficient
force; F, a cylindrical body, forming the internal part of the mill, which
may be composed of cast or wrought iron, or any other proper materials, and
may be solid or hollow, as shewn by the dotted lines on the Drawing; G, the
upper or breaking teeth, which may be extended higher as may be found
necessary for the different purposes for which the mill is intended; H, the
lower inner,ör grinding teeth'; 'I,'the hollow external cylinder, containing on
the inside the outer grinding teeth; this cylinder 'may be composed of the
same materials as the inner cylindrical body, and may be secured by strap
bolts or other proper fastenings' to the posts Q, Q, of the supporting frame.
K, the lower gudgeon, secured to the shaft, as the upper gudgeon; L, the
iron, brass, or other metallic step let solid into the upper cross rail R, for s
the purpose of preventing any lateral motion in the lower gudgeon'; M, the
regulating screw, passed through the nut N and lower rail R for raising "'or
lowering the internal part of the mill, for the purpose of obtaining a coarser
or finer operation. in the works; O; the hopper, affixed on the outer cylinder..
to receive the several articles that are to pass through the mill; "this 'hoppers
may be composed of wood or any other proper materials; "P, the 'hollow-
conical covering over the inner part of the mill, which may be of the same.
kind of materials as the hopper O. The frame for supporting the works
consists of posts Q Qlet into the ground' at four angular points, to which are
connected the lower rail R; and two upper rails R, crossing Feach other at
right angles. Between the posts are to be fitted, 'from' the underside of the
cylindrical body F to the floor, wire sifters, for the purpose of separating the
finer from the 'coarser parts of the articles passing through the mill.3
Having thus explained the principles of "my: Invention and the manner in
which they may be applied, "I observe, that "the materials inay be of various
qualities; sizes, and substances, capable of being applied to the fuses, strength,
and purposes for which they are intended, and that the sizes and strength of
the several parts of the machines for mills may be varied, according to the
nature and extent of the works to be performed; therefore are not subject to

page_text: any precise dimensions, form, or quality of materials, and may be worked
by a horse or horses, water mill or wind mills, steam engines, or by any
other proper power, and may be applied not only to the purposes before
mentioned, but likewise will be particularly useful for grinding of brill for
soap-boilers and others, clay for making bricks and tiles, and may also be
applied to many other serviceable purposes.
In witness whereof, I, the said James Weldon, have hereunto set my
hand and seal, this Twenty-fifth day of December, in the year of our
Lord One thousand seven hundred and ninety-seven.
AND BE IT REMEMBERED, that on the same Twenty-fifth day of
December, in the year above mentioned, the aforesaid James Weldon came
before our Lord the King in His Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained, in form above written.
And also the Specification aforesaid was stamped according to the tenor of
the Statute in that case made and provided.
Inrolled the Twenty-seventh day of December, in the year above written.
