Year: 1827

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
FELTON, of Hinckley, in the County of Leicester, Machine Maker, send
greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Twenty-eighth day of June, in the eighth year of
His reign, did, for Himself, His heirs and successors, give and grant unto me,
the said John Felton, my exors, adñiors, and assigns, or such others as I, the
said John Felton, my exors, adññors, or assigns, should at any time agree
with, and no others, from time to time and at all times during the term of
years therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, and
also in all His said Majesty's Colonies and Plantations abroad, my Invention
of "A MACHINE FOR AN EXPEDITIOUS AND CORRECT MODE OF GIVING A FINE EDGE
TO KNIVES, RAZORS, SCISSORS, AND OTHER CUTTING INSTRUMENTS;" in which said
Letters Patent is contained a proviso obliging me, the said John Felton, by an
instrument in writing under my hand and seal, particularly to describe and
ascertain the nature of my said Invention, and in what manner the same is
to be performed, and to 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 recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Felton, do hereby declare the nature of my said Invention to consist
in a machine for sharpening various cutting instruments, and particularly
knives, by passing their edges backwards and forwards in an angle formed by
the intersection of two or more circular files or other suitable surface, in
manner herein-after explained; and in further compliance with the said pro-
viso, I, the said John Felton; do hereby describe the manner in which my
said Invention is to be performed, by the following description thereof,
reference being had to the Drawing annexed, and to the figures and letters
marked thereon, that is to say :-
DESCRIPTION OF THE DRAWING.
Figure 1 represents one of my said machines adapted for the sharpening of
table knives. A is the pedestal; B, B, two uprights; C, C, two steel cylin-
ders or rollers turned down or reduced at the parts marked r, and revolving
easily on axes at their ends, bearing in the uprights B, B. The larger parts
of the cylinders or rollers, and which are marked S, are grooved or grained in
a circular direction by means of an ordinary engraver's shader, and thus have
a surface given to them something like the sort of file which is generally
called a float. The dotted lines represent the position in which the knife or
other cutting instruments to be placed for the purpose of being sharpened,
and it only requires to be passed a few times to and fro in the position here
shewn to effect this purpose. Figure 2 is a plan of the said machine, shewing
the relative situation of the cylinders C, C, and the manner in which the
larger circles or circular vosses marked S intersect each other. Figure 3-is
a transverse section of the said machine.
.
Now whereas the cylinders may be made of steel or any other suitable metal
or hard material, and the surfaces of the circular vosses may be engraved or.
otherwise brought to a fine or rough state according to the delicacy of the
edge required, and the slit marked f in the Drawing may be varied in 'shape;"
the better to hold whatever form of instrument it may be required to sharpen.
But I claim as my Invention the machine herein-before described for the
purposes aforesaid; and such machine being, to the best 'of my knowledge and
belief, entirely new, and never before used within that part of His said Majesty's
United Kingdom of Great Britain and Ireland called England, his said
Dominion of Wales, or Town of Berwick-upon-Tweed, 'nor in any of His said
Majesty's Colonies or Plantation's abroad. I do hereby declare this to be my
Specification of the same, and that I do verilý believe this my said Specification
doth comply, in all respects, fully and without reserve or disguise, with the

page_text: proviso in the said herein-before in part recited Letters Patent contained;
wherefore I do hereby claim to maintain exclusive right and privilege to my
said Invention.
In witness whereof, I, the said John Felton, have hereunto set my hand
and seal, this Thirteenth day of July, in the year of our Lord One
thousand eight hundred and twenty-seven.
