Year: 1809

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Jonn
DUFF, of Great Pulteney Street, in the County of Middlesex, Cutler, do send
greeting.
WHEREAS His most Excellent Majesty George the Third, by His Letters
Patent, bearing date at Westminster, the Fourteenth day of December now
last past, did give and grant unto me, the said John Duff, my executors,
administrators, and assigns, His special licence, full power, sole privilege and
authority, that I, the said John Duff, my executors, administrators, and assigns,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, an Invention communicated to
me, the said John Duff, by a foreigner, of. "SNUFFERS ON A NEW AND IMPROVED
CONSTRUCTION;" in which said Letters Patent there is contained a proviso,
obliging me, the said John Duff, under my hand and seal, to cause a particular
description of the nature of the 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 next and immediately 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
John Duff, do hereby declare that the said Invention is fully described by the
Drawings in the margin of these Presents, and the following description thereof,
that is to say-
Fig. 1 is a perspective view of the snuffers, with the top plate taken off to

page_text: shew the work within. a, a, is a scraper, turning on pivots, one in the socket b,
and the other underneath and perpendicular to it; c, a spring pressing thro'
an opening in the scraper, to force it rapidly back against the valve or hanging
door d, which has a prominent peg facing the scraper, by which it is pushed
as the door (c) of the snuffer closes, and raises the valve (d) to let the snuff
pass into the receiver (f); it shuts again by its own weight. The scraper
being of the same size as the valve or hanging door, aets as a second door to
the the receiver until drawn back by opening the snuffers, and then the valve
resumes its place. Fig. 2 represents a piece of iron, which acts as a lever to
draw the scraper forward and backward; its situation is shewn by the dotted
lines in Fig. 1. The crooked end of this lever is inserted in the hole a, Fig. 3,
which is a plan of the scraper. The other end has an oval hole in it, and is
held by a peg fixed in one of the shanks of the snuffers near to its left edge,
and, on account of the oval form of its aperture, draws forward the scraper on
opening the snuffers, and pushes it backwards as the snuffers close. The door
for emptying the receiver is at the end of the snuffers, and opens and shuts,
by pressing the point of the snuffers upwards or downwards. This door is
kept closed by an inside spring. The two semi-oyal cuts, the one plain, the
other with a few sharp edges on the point of the snuffers, are shewn only. as a
better means of removing splinters or thieves in the wick of the candles, and
which may or may not be added at discretion.
In witness whereof, the said John Duff hath hereunto set his hand
and seal, this Thirteenth day of January, in the year of our Lord One
