and granted unto JOHN SORBY, the younger, of Sheffield, in the County
of York, Edge Tool Maker, his exors, adñors, and assigns, His special
licence, full power, sole privilege and authority, to make, use, exercise,
and vend, for the term of fourteen years, a certain Invention of "A
METHOD OF MAKING AN AUGER FOR THE USE OF SHIPWRIGHTS, MILLWRIGHTS,
CARPENTERS, AND OTHER ARTIPICERS, UPON A NEW AND IMPROVED CONSTRUCTION;"
in which said Letters Patent is contained a proviso that if the said John
Sorby should not particularly describe and ascertain the nature of his said
Invention, and in what manner the same is to be performed, by an in-
strument in writing under his hand and seal, and cause the same to be
inrolled in His said Majesty's High Court of Chancery within two calendar
months next and immediately after the date of the said Letters Patent,
that then the said Letters Patent, and all liberties and advantages thereby
granted, should utterly cease, determine, and become void, any thing therein-
before contained to the contrary in anywise notwithstanding, as, by reference
to the said Letters Patent, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Sorby, do hereby declare that my said Invention is described and
ascertained in and by the Drawings in the margin of these Presents, and in
manner following, that is to say :-
My Invention consists in the addition of a screw, formed at the nose or
extremity of the shell of the auger, to precede the entrance of the shell or
bit, and also in varying the shape of the nose of the auger, as described in
Figures 2, 3, and 4 of the said Drawings, and as follows:-
Fig. 1 represents an auger of the usual form. a, b, is the shell; c, d, a part
of the shank; e, e, is the nose or cutting part.
Fig. 2 represents an auger with one of my new-invented screws and noses.
f is the screw. g, g, h, h, is the nose or cutting part tapering from h to g.
Fig. 3 represents another auger with another of my new-invented screws
and noses. i is the screw, which is not a complete screw, the thread being
continued only a part of the way round, the other part being either round, flat
or hollow; g, g, h, h, is the cutting part.
Fig. 4 represents another auger with another of my new-invented screws
and noses. k is the screw; 1, 1, is the nose or cutting part; m, m, n, n, is the
shell or bit, that part of the bit m, m, being concave, and the part n, n,
convex. I do not confine myself to any exact length, shape, or strength, or.cut
of the thread of the screw, neither do I confine myself to any exact shape of
the nose or cutting, but shall vary them, the better to answer the purposes for
which they may be intended.

thousand eight hundred and sixteen.
