Year: 1783

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, greeting.
WHEREAS His present most Excellent Majesty King George the Third,
by. His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Seventeenth day of December, in the twenty-fourth year of
His reign, did give and grant unto me, JONAS JONAS, late of White Bear
Court, White Chapel, in the County of Middlesex, but now of Little Mitre
Court, Duke Street, in the Parish of Saint James's, Duke Place, in the City
of London, Lead Pencil Maker, His especial licence, full power, sole privi-
ledge and authority, that I, the said Jonas Jonas, my executors, adminis-
trators, and assigns, and every of us, during the term of years therein expressed,
should and lawfully might use, exercise, and vend my "NEW-INVENTED SLIDING
LEAD PENCILS," within that part of the Kingdom of Great Britain called
England, the Dominion of Wales, and Town of Berwick-upon-Tweed, in
such manner as to me, my executors, administrators, and assigns, or any of us,
should in our discretion seem meet; in which said Letters Patent is con-
tained a proviso, that if I, the said Jonas Jonas, should not particularly describe
and ascertain the nature of my said Invention, and in what manner the same
is to be performed, by an instrument in writing under my hand and seal, and
cause the same to be inrolled in His Majesty's High Court of Chancery
within four kalendar months next and immediately after the date of the said
Letters Patent, that then the same Letters Patent, and all liberties and advan-
ages whatsoever thereby granted, should utterly cease, determine, and become
oid, as in and by the said Letters Patent more at large doth appear.

page_text: NOW KNOW YE, that I, the said Jonas Jonas, in pursuance of and in
compliance with the said proviso, and the purport and true intent and meaning
of the said Letters Patent, and of His Majesty's said most gracious intentions,
do, by this Instrument in writing under my hand and seal duly executed,
declare that my said New-invented Sliding Lead Pencils is described to be 5
made and performed in manner following (that is to say):-
First, the form and materials of my said new-invented sliding lead pencils
must, in the first place, be made on the old construction of common lead
pencils till fit for glueing.
Secondly, the sides of the bottom must be cut down to the depth proper for 1
the dovetail.
Thirdly, plough the depth of the top equal to the raised part of the bottom
and the breadth of the groove which is ploughed in, but observe that the top
must be narrower than the raised part of the bottom.
Fourthly, dovetail the groove in the top with a dovetail tool, and likewise
the raised part of the bottom, till it fits in the groove of the top which is
dovetailed.
Fifthly, take them asunder and cut about an inch of the raised part of the
bottom, at the end where there is no lead. Two holes must be drilled in the
raised part of the bottom; one hole must be an eighth part of an inch from
where the lead ends, the other hole must be drilled at the said end of the
raised part an eighth part of an inch from the said raised part which is so cut
away.
Sixthly, you must then plough a groove in the middle of the dovetail groove
in the top, to the size necessary for the top spring or pin.
Seventhly, a hole must be drilled through the sides of the top, at the end
where the ploughing stops in the groove in the dovetail groove.
Eighthly, make the pencil round.
Ninthly, the groove in which the spring or pin aforesaid is to slice must be
ploughed in the dovetail top, and must be made with a head and fixt in that
hole which is at the end of the raised part of the bottom.
Tenthly, when the top spring or pin is in, both parts must be made even,
and then a stop must be glued in the dovetail groove, the length of an inch,
which fills up the vacancy of the part cut away of the raised bottom.
Eleventhly, the wire must be put through the holes drilled at the sides of
the top, which prevents the spring or pin from sliding any further, and himlers
the pencil from coming asunder and from being out of repair, and by which
means when a point is cut to the part where lead is, the other part is a com
pleat case for preserving the point from breaking.

page_text: Twelfthly, drill a hole through the top and stopper, and put in a pin, and
make a notch close to it, and likewise a spring or pin must be put in the holo
drilled in the bottom where the lead ends; then a notch must be cut close to
the pin in top and bottom for the conveniency of sliding the parts backward
and forward. Next mark a six-inch rule on the top with rule makers' tools;
then polish it with a fish skin, and it is compleatly finished.
In witness whereof, I, the said Jonas Jonas, have hereunto set my
band and seal, this Fifteenth day of April, One thousand seven
